飞泛(Futaba)Futaba14SG R7 firmware更新说明书
February 2020—Firmware and FAA RID NPRMAs February greets us many have chosen to set theirhobby interests aside, or at least limit their participa-tion to inside for the past couple months. The winterbuild is a time-honored tradition in the northern cli-mates. In addition to getting new aircraft ready forwhen the weather warms and the winds calm it’s theperfect time to give our existing airframes a thoroughexamination for signs of wear, or potential failure. It’salso a good time to check to see if our transmitters, re-ceivers, or ESC’s may have pending firmware updates.The advantage of firmware updates is they often givenew capabilities for your existing hardware, or fix pre-viously unknown defects. However, sometimes as newfeatures are introduced or patched another featuremay be inadvertently broken by the update. The avail-ability of an update does not mean it’s necessary foryour use. As an example, when Futaba released up-date 7 for the Futaba14SG they inadvertently intro-duced a range check failure on startup. Futaba recent-ly introduced update 9 to fix the range check failure onstartup issue. Firmware updates tend to be an iterativeprocess with customers being the final test of function-Futaba Software DownloadFrSky Important Update for ACCST D16 FrSky Firmware Downloads Spektrum Firmware Updates Jeti Firmware Updates Graupner Updates Castlelink UpdatePersonal safety is not the only topic to discuss this month. The survival of our hobby is very much threatened by the recent FAA RID Notice of Pro-posed Rulemaking (NPRM). The FAA published their plan requiring broadcast from all aircraft weighing over 250 grams (0.55 pounds) on Dec 31. ality. FrSky recently released a new firmware for ALL of their D16 ACCST transmitters and receivers back to 2013 (OpenTX as well as FrOS). The firm-ware addresses a serious issue –if you’re in the Eu-ropean Union. The FCC (American) version of transmitters/receivers are not significantly affect-ed, especially if operated where the airwaves are not crowded with many 2.4ghz signals. One take-away from this is noting that when applying radio firmware updates be sure to note that you have downloaded FCC version and not EU. I recom-mend waiting on the FrSky ACCST updates for a couple months as this is a major update and there will inevitably be bugs. I’d rather do the updates one time since this transmitter update also requires that all receivers are updated.In summary; when checking over all the clevises, horns, pushrods, screws, motor mounts etc, don’t forget to check where you stand regarding what you can’t see –the firmware. Additionally, be judi-cious about applying a recently introduced firm-ware especially if it’s a major update. Finally, be sure you’re using the FCC radio firmware and not the EU version.Don’t be misled by the term “drone” in the NPRM. The FAA uses the term “drone” to apply to all Un-manned Aircraft Systems(UAS), this includes every-thing we fly at TCRCM field and may even include free flight and control line. This NPRM is open for public comment until March 2. The AMA, and EAA (Experimental Aircraft Association) as well as others petitioned in vain for an extension to the comment period. In response to the request for an extention FAA replied on January 28:“…the need for remote identification of UAS increas-ingly has become important as new public safety and national security concerns arise regarding the use of UAS. Accordingly, the FAA has determined that any extension of the comment period, and the subse-quent delays in promulgation of a final rule imple-menting remote identification of UAS, would not be consistent with the safety and security objectives of the proposed rule.Therefore, your request to extend the comment pe-riod for the Remote Identification of Unmaimed Air-craft Systems NPRM is denied. The comment period for the NPRM closes on Monday, March 2, 2020.”Once one dives into the 319 page NPRM in depth it details how the FAA is proposing to progressively annihilate the hobby. This NPRM proposes to make it illegal for a land owner to fly over their own land in the short term, and eventually eliminate model flying fields for home-built aircraft like we now fly. There are many many levels of concern. Grouping Line of Sight (LOS) modeling in with the regulations of Beyond Visual Line of sight BVLOS operations is a one size fits all solution that is inappropriate. Making it impossible to establish new flying fields, or even move an existing club flying field to a new location is well beyond what Congress mandated in the FAA reauthorization act of 2018. To assist with digesting the information about the NRPM, Jim Andersan has posted a page of infor-mation on the Club Website. There are also links to two summaries of the NPRM in the sources below.It’s seriously imperative that all interested reach out to the FAA and to all elected representatives. Even if your position is that you have no intention of follow-ing these rules then politely tell the FAA that they can expect noncompliance from otherwise law abid-ing citizens.Some would say that contacting FAA or representa-tive will make no difference. If that’s the case we’re no worse off and you did what you could. Your com-ments MAY make a difference in which case it’s time and energy well spent.Links to Contacts:• Dan Newhouse• Patty Murray• Maria Cantwell• White House• FAA RID NPRM Comment pageLinks to Information and resources.• Layman’s Guide to the NPRM for Remote ID• AMA summary of the RID NPRM• AMA Templates to use to assist in drafting your own response.• Our club website。

高通QMI协议
⾼通QMI协议QMI(Qualcomm MSM Interface,官⽅名称应该是Qualcomm Message Interface)是⾼通⽤来替代OneRPC/DM的协议,⽤来与modem通信。
QMI协议定义了多个服务: DMS(设备管理Device Management) 提供载⼊设备信息的功能 NAS(⽹络访问Network Access)提供欧冠你注册⽹络的动作 WDS(数据连接)PDS(GPS定位报告) UIM(管理User Identity Module) CTL(控制服务:⽤户发起其他服务请求前,必须先申请 ClientID, 这个ID就是由控制服务分配的, 这个服务永远在线)协议⾥的每个服务都定义了请求和响应(也叫做 Indication) 每个请求响应都有⼀个匹配的ID,这样⽤户可以⼀次发出多个请求。
并且响应也不必严格按照请求的顺序进⾏回应。
Indication作为主动提供的消息,要么发送给某个特定的客户端, 要么是⼴播消息(⼴播给所有使⽤这个服务的客户)。
通常情况下,⽤户需要通过⼀些请求/响应来打开indication协议中的每条消息都定义了⼀系列输⼊(在请求中才有输⼊)参数,或者输出(在响应或者indications中才有输出)参数。
这些参数,我们命名为TLVQMI协议可以通过Linux kernels (>= 3.4)来访问。

性侵幼女犯罪之成因及其防范
第30卷第6期2013年12月政法学刊JournalofPolticalScienceandLawVol畅30No畅6Dec畅2013性侵幼女犯罪之成因及其防范周 玲(广东警官学院公共课教研部,广东广州510232) 摘 要:近年来性侵幼女犯罪案件频发已经引令人瞩目,究其原因是多方面的,社会道德沦丧致使道德底线崩溃、传统文化的心理模铸、职业道德意识淡漠部分幼儿监管不到位、防性侵意识弱、不少施暴者应该说有着猎奇甚至是变态心理、家丑不可外扬思想作怪等等不一而足。
这就要求我们必须有针对性地采取防范措施,严惩犯罪犯罪嫌疑人,坚决杜绝类似事件的发生,保持高压的态势,在人们的心里筑起一道不可逾越的鸿沟,让胆敢以身试法之人得到应有的下场;细化和完善有关的法律法规,使不法分子无机可乘;加强职业道德建设,设置更高更合理的进人门槛和用人评价机制,注重从业人员道德品格的考核和评价;加强对于未成年孩子的安全意识的教育和引导。

近两年来,各大媒体上常有醒目的标题报道或评论有关性侵幼女行为,这类事件之所以令人关注和愤怒,自然除了是因为这些无辜的幼女年龄之小、受伤害程度之深以外,还有就是施暴着的身份特殊:小学校长、政府官员、中小学教师、幼儿园员工、乡村的老农、已经参加工作的大学生等等。
这些事件的发生令人发指,叫人痛心,值得深思,我们要高度重视,进一步加强制度建设和职业道德约束力,尤其是人性素养的提高是当务之急,进而要灭除这些丧尽天良的恶性事件的发生,纯净我们生活的环境,让孩子们生活在安全健康的环境里茁壮成长。
一、近年来性侵幼女案件频发性侵害是指加害者以权力、暴力、金钱或甜言蜜语,引诱胁迫他人与其发生性关系,并在性方面造成对受害人伤害的行为。

ACCA F5考前Tips:考试重点题型解析(上)
ACCA F5考前Tips:考试重点题型解析(上)读完这个东西只需要30分钟,但是做完这个东西拟定的任务需要7天。
但是,正好来得及~拿去!一包干到发燥的,点火就着的干货!Part oneGeneral causes of failure in F5 Exam做题顺序从考后的问询调查来看,相当一批学生一开始就选择攻克后面的大题: 手忙脚乱的先做完大题,发现只有20分钟来做前面的选择题了,因此闭上眼睛勾选,这基本等于自寻死路:不管难易,分值一样。
考试是现实而残酷的游戏,只会以成败论英雄。
要和我煮酒论英雄?我们考完试先!➤Tip: 请先完成SectionA, Section B的选择题, 这是性价比最高的两个部分.时间管理这个是通病,很多同学花时间在他们会做的题目上,跳过不会做的题目...另一位同学的留言: 通宵背了Advanced variance的公式,发现在选择题中用上了,兴奋得两眼放光,一个饿虎扑食,以难分难舍之势跟这个题浪了6分钟!交卷之前不放心,又花了3~4分钟重新验算的一遍!!哥!你对我是真爱,但是我只值2分!本来3.6分钟的事情你花了8分钟!你效率真高!➤Tip: 考前必须最少做10套真题,考前两天最少再做2套历史真题(严格控制时间)生僻考点本次出现了ROLLINGBUDGET的大题. 这个知识点属于常规低频考点(即:授课必讲,但出现在大题的概率不高, 最近一次是2012年12月的Designit Co). 虽然比较生僻,但是知识点覆盖极其常规,一定是Definition(What),Suitability (how), Advantage and Disadvantage (why).按照这个吃遍天下的套路,哪怕只是有模糊印象, 如果可以将这些印象和案例内容结合论述一下, 估计会有30%~40%的有效分。
但是我们一看到这种长得比较陌生的题,第一秒想到的居然不是知识,而是放弃!于是完全不下笔的童鞋很多!你不抓分,分不会从天上掉下来。

Any negligence can throw years of hard work down the drain, so aerospace engineers are obsessed with quality.
A scientist works in a remote control room at the China Academy of Space Technology on January 25.
“More than 10 years have breezed by in the blink of an eye,” she remarked while flipping through the photos taken at the front gate of CAST.
China’s Chang’e-4 lunar probe made the first ever soft-landing by a spacecraft on the far side of the moon on January 3, and the China National Space Administration dubbed the lunar probe mission a success on January 11.
Since the moon’s far side is also more pockmarked than the near side, rover Yutu-2 faces bigger challenges than its predecessor Yutu which landed in 2013. Wen, a key designer of Yutu-2, said the rover was improved significantly to prevent mechanical failure.
新课程标准下任务驱动教学模式在《小学班主任工作实务与技能训练》课堂教学中的应用
班主任工作技能训练系指“班级管理、对学生进行思想品德教育和组织指导学生进行课外活动等方面的技能训练”。
它是以教育学、心理学等学科的基本理论为指导,理论与实践相结合的教学实践活动。
班主任工作技能训练是当前小学教师职业技能训练的重要组成部分,掌握班主任工作技能是教师的必备条件之一。
因此,作为初等教育专业的师范生,加强班主任工作技能训练,是学校教学工作中不可缺少的内容。
在新课程改革的背景下,尽管许多师范院校已经开始重视对师范生进行班主任技能训练,但都普遍存在诸多问题,如培养目标定位不准确、技能训练形式单一等,致使师范生班主任技能普遍欠缺。
针对这类情况,有必要在基础教育新课程标准下展开对师范生的班主任技能训练体系与教学模式的研究,以期全面提高初教专业师范生的技能训练水平。
一、“任务驱动”教学模式的意义1.“任务驱动”教学模式的含义。
“任务驱动”是一种建立在建构主义学习理论基础上的教学法。
建构主义学习理论强调:学生的学习活动必须与任务或问题相结合,以探索问题来引导和维持学习者的学习兴趣和动机,创建真实的教学环境,让学生带着真实的任务学习,以使学生拥有学习的主动权。
“任务驱动教学模式”是在创新教育、素质教育的教育思想指导下,建立在建构主义学习理论基础上的,通过教师在教学过程中设置引导启发性的学习任务,激发学生学习的动机和兴趣,促进学生自主学习,自主探究,培养学习者自主解决问题的能力的一种稳定的教学结构的形式”。
2.“任务驱动”教学模式的实践意义。
①《小学班主任工作实务与技能训练》课程的特点。
本课程旨在培养我院学生必备的小学班主任从业专长,以掌握小学班主任工作实务为出发点,以班主任所应具备的知识为基础,注重小学班主任工作的技能方法和实践能力的培养与训练。
本课程还充分考虑到师范生应具备小学班主任的工作所需要的基本素养并明确对其进行职前培训的职责,降低小学班主任培养的经验性、盲目性和随意性,从而提升小学教师,特别是从事班主任工作的教师的培养质量,为班主任从业提供了基础性的要求,有利于学生职前与职后的一体化及可持续发展。

Research Progress of Application of Porous Polymer in Energy Storage
Research Progress of Application of Porous Polymer in Energy StorageFang Zhang, Yang YuUrban Construction Engineering Department, Huazhong University of Science and TechnologyWenhua College, 58thGuanshan 3Road, Wuhan, Hubei Province, China,430074fangchang8188@Keywords: Polymer, porous materials, energy storage, porous carbonAbstract: Nowadays, one of the research emphases in clean energy field is to apply porous polymer as energy storage media to capture and save abundant energy. Researches in this area focus on theoretical methods and syntheses of new materials. Researches on theoretical methods include investigations on mechanical strength, characteristic of heat and mass transfer, internal structure and hydrophilicity of materials using mathematical, physical and chemical methods. Syntheses of new materials include synthesis of porous carbon and porous metal organic frameworks materials and construction of battery structure use polymer organics as matrix.IntroductionUnder the circumstances of fossil energy shortage and global warming, research on clean energy is becoming more and more important. One of the most important topics is to find appropriate energy carrier and effective and doable methods to capture H 2, CH 4 and CO 2 in limited space. Nowadays, researches are focus on theoretical methods and syntheses of new materials. Polymer porous materials have been applied in fuel cell, solar cell, lithium ion battery and super capacitor to store energy. 1 Researches on theoretical methodsResearches on theoretical methods mainly include mechanical strength, characteristics of heat and mass transfer, internal flow field, channel structure, transfer characteristics of two-phase flow, hydrophilicity of materials and water swelling of electrode. These researches used methods such as simulation, mathematical modeling, geometric blur, particle element, and by means of techniques like neutron scattering, gas absorption, neutron radiography and electrochemical impedance spectrometry. Jiang, JW, et al. [1] summarized the function of molecular simulations in application research on nano-porous materials in energy area, and proved that molecular-level studies can bridge the gap between physical and engineering sciences. Thi X. T. Sayle et al. [2] simulated the mechanical deformation of meso-porous Li-−MnO 2 under stress using molecular dynamics simulation, and generated a full atomistic model of meso-porous β-MnO 2 to explain volume changes during charge/discharge cycles in rechargeable Li-ion battery materials. Hiroyasu Furukawa et al. [3] measured H 2, CH 4, and CO 2 isotherm of seven porous covalent organic frameworks (COFs). The results proved that material with the best performance rivaled the best metal-organic frameworks and other porous materials in their capacities. Linli He et al. [4] compared surface areas of four nano-porous carbons obtained by small-angle neutron scattering (SANS) and CO 2 and N 2 sorption, found that calculation data of pore size obtained from SANS were similar to results obtained from X-ray scattering to similar porous carbon materials. Yasutaka Nishida et al. [5] numerically studied a model of porous composite microstructures for solid oxide fuel cell anodes with three-dimensional particle element method, and found that the numerical results were in good agreement with the experimentally measured triple-phase boundary density. M. Maidhily et al. [6] used Electrochemical Impedance Spectroscopy to evaluate two different types of gas diffusion electrodes for polymer electrolyte membrane fuel cells (PEMFCs). It was observed that the two types of electrodes with double side gas diffusion layer (DSGDL) and single side gas diffusion layer (SSGDL) showeddifferent behavior with respect to operating conditions. The DSGDL is favorable for operating at higher temperature and relative humidity, while SSGDL is favorable under dry gas operation. Naiqing Zhang et al. [7] used the breath figures method, prepared honeycomb porous La0.6Sr0.4Co0.2 Fe0.8O3−δ –Gd0.2Ce0.8O2−δ (LSCF–GDC) composite cathodes with nontoxic and easily available water droplets as templates. The Scanning Electron Microscopy micrographs suggested that experimental conditions and concentration of polymer and LSCF–GDC powder affected the pore structure of the membranes. Energy capacity of porous carbon materials relates to the surface properties. Researches on surface area, internal surface structure and internal surface flow field of porous materials are also of great importance. Joshua S. Preston et al. [8]investigated gradual property change between the micro-porous layer and the macro-porous layer of bilayer diffusion media, and developed a mathematical model describing the effects of this gradual interfacial region. Yun Wang[9] investigated porous medium flow field of polymer electrolyte fuel cells, and proposed an approach of channel development for polymer electrolyte fuel cells (PEFCs), i.e., to fill porous media in the channel region, allowing a simultaneous transport of gaseous reactant, liquid, heat, and electron through the porous-media channel. On this basis, Yun Wang [10]analyzed the two-phase transport in the porous-media channel for PEFCs and found that the impact of capillary action can be neglected for the liquid transport along the channel.Catalyst and hydrophobicity of porous materials are important to electrodes performance, and water management is one of the most important factors for improving the performance in PEMFCs. The micro-porous layers in the membrane electrode assembly provide proper pores and paths for mass transport, thereby allowing for the control of the water balance. Minjeh Ahn et al. [11] studied the influence of hydrophilicity in micro-porous layer for PEMFCs. The result indicated that the hydrophilicity control in the micro-porous layers has a positive effect on the water management in PEMFCs. S. Pulloor Kuttanikkad et al. [12] simulated pore network to study water transport in a model gas diffusion layer of PEMFCs in relation with the change in hydrophobicity that might be due to aging or temperature effect. The system was found to be weakly dependent on the fraction of hydrophilic elements as long as this fraction was below the percolation threshold, whereas an increase in wettability above the percolation threshold diminished access of gas to the catalyst layer.2 Researches on syntheses of new materialsPolymer porous materials include porous carbon, porous metal organic frameworks (MOFs) materials and others have been widely used in energy storage area. Construction of batteries using different kinds of polymer organic materials as matrix is one of the research focuses.2.1 Porous carbon materialsIn energy industry, porous carbon materials are widely used to produce electrode and batteries with super capability to store energy, H2and CH4for the low price, long service life and stable performance. Characteristics of porous carbon materials are affected by both the carbon structure and property of the pores. Martin Oschatz et al.[13]obtained a hierarchical and highly porous carbide-derived carbon (CDC) by nano-casting of pre-ceramic precursors into cubic ordered silica and subsequent chlorination. Resulting CDC replica materials show high methane and n-butane capacity. In order to prove the feasibility of using porous carbon foam material in a proton exchange membrane fuel cell, Jin Kim et al. [14] constructed a single PEMFC with reticulated vitreous carbon foam. Compared with that of a conventional fuel cell, this cell produced comparative power density. Du He Yun et al. [15] obtained catalyst layer comprising of low loading of platinum nano-particles supported by a directly grown micro-porous carbon nano-tube (CNT) layer, and combined this catalyst layer on a proton exchange membrane fuel cell. Results showed that the cell performed well without exhibiting water-flooding.2.2 MOFs materialsPorous MOFs materials experienced great development in the last decades. Their chemically-tunable structures and functionality nano-space in skeleton played an important role in the storage of H2 and CH4, capture of CO2, gas separation, catalysis and fuel cell. Ma, TY et al. [16] combined a considerablenumber of organic functional groups into the metal phosphonate hybrid framework, and obtained meso-porous metal phosphonates. Small amount of organic additives and the pH value of the reaction solution have a large impact on the morphology and textural properties of the resultant hybrid meso-porous metal phosphonate solids. The materials have impressive performances in the fields of energy.2.3 polymer organic matrixConstruction of batteries using different kinds of polymer organic materials as matrix is one of the research focuses. Prabal Sapkota et al. [17] designed and manufactured a zinc air fuel cell of taper-end structure with a polyamide-base engineering plastic. The air cathode with multiple layers of MnO2 and CeO2 showed a remarkably stable electricity-generating performance even at high current density. Tienhoa Nguyen et al. [18] synthesized a highly porous polyimide film with tunable pore size, porosity and thickness, and then used this film as matrix to construct a Nafion-infiltrated composite membrane. This membrane demonstrated significantly improved performance. Lawrence Berkeley National Laboratory developed a new kind of compound material composed by nano-particles of Mg dispersed by methacrylate polymer as matrix [19]. Mg contained abundant vacancy which could deposit H2, and polymer matrix provided the best barrier property. This compound material did not need high temperature to absorb and release H2, and avoided metal oxidation, overcame the main technical obstacle of H2 storage. Sung Hyun Yuna et al. [20] reported a novel non-fluorinated composite polymer electrolyte membrane reinforced by an electrospun nano-fiber porous substrate having a symmetrically pore-filled structure. Water swelling of the membrane was significantly suppressed and the proton conductivities were improved, performances in a H2/O2 fuel cell were also greatly enhanced. A. Eguizábal et al. [21] developed a novel hybrid membrane based on polybenzimidazole and ETS-10 titanosilicate type materials functionalized with sulfonic groups, and this membrane had been used in high temperature proton exchange membrane fuel cells applications, consequentially, the conductivity values of the membrane were improved.3 ConclusionsAs the research progress of theoretical methods and syntheses of new materials, porous polymer like porous carbon materials, MOFs materials and polymer organic matrix, should get increasingly great attention and affirmation in energy storage field.References[1]Jiang JW, Babarao R, Hu ZQ, Molecular simulations for energy, environmental and pharmaceutical applications of nanoporous materials: from zeolites, etal-organic frameworks to protein crystals, Chemical Society Reviews. 40 (7) (2011) 3599-3612.[2]Thi X T Sayle, Phuti E.

前人针对安丘-莒县断裂的活动时代、古地震事件及几何结构进行了大量研究,但多集中于断裂出露区,对断裂隐伏区的研究相对较少。
文中利用野外地质调查、浅层地震勘探、钻孔联合地质剖面及古地震探槽等深、浅、表立体式多层次研究方法,重点开展安丘-莒县断裂新沂段的几何结构特征研究,分析其平面几何展布特征和深、浅、表构造关系,填补安丘-莒县断裂新沂段隐伏区活动特征的研究空白。
结果表明,安丘-莒县断裂新沂段自北向南可分为北马陵山—官庄段、官庄—唐店段和唐店—新店段3段;中段以双支的走滑兼正断活动为主,向南、北两端转变为单支的走滑兼逆冲;基岩顶垂直位移在中部最大,约为230m,向两侧逐渐变小,表现为螺旋状的枢纽运动。
安丘-莒县断裂新沂段的深、浅表呈现成因相同和几何结构协调的变形特征,在深部表现为单支,切穿白垩纪地层向上延伸,在浅表层沿基岩山与第四系软土层接触面向上破裂,在南马陵山和北马陵山处表现为单支,多处破裂至地表。
统计假设检验中原假设HO和备择假设H1的探讨
在统计学教学实践中,参数的假设检验占有独特、重要的地位。
在教学中,笔者发现大多数学生及统计工作者甚至个别青年教师假设检验的原理理解不到位,突出表现在对原假设与备择假设的设定上觉得无从下手,掌握不好,有时在判断结论上会出现截然相反的结论,这种情况的发生,使得在教学过程中引起混淆,甚至怀疑假设检验本身的正确性。
基于此,本人谈几点看法。
一、假设检验的基本思想及基本原理假设检验是事先对总体参数或分布形式作出某种假设,随后由所抽取的样本构成检验统计量,根据统计中的小概率原理,即“小概率事件在一次试验中几乎不可能发生的”。
依据样本信息,对于提出的假设作出判断:是接受,还是拒绝,这种基本思想是带有概率性质的“反证法”。
为了判断一个“结论”是否成立,先假设该“结论”成立,称此“结论”成立为原假设,记为H0,与之对立的“结论”,称为备择假设,记为H1,在原假设H0成立的前提下运用统计分析的方法进行推导和计算,如果得到一个不合理(小概率事件在一次试验中发生了)的现象,就有理由怀疑原假设H0的正确性,从而拒绝原假设H0。
反之,若没有出现上述这种不合理现象的发生,就没有理由拒绝原假设H0,即可以接受原假设H0。
由于样本的随机性,无论是拒绝H0,还是接受H0,我们都无法保证假设检验的结果绝对或者是完全的正确,也可能会出现错误判断,从而导致犯两类错误。
第Ⅰ类错误一般叫做“弃真”错误:如果原假设H0为真时,错误地拒绝了H0,那么就犯了弃真错误,记为P{拒绝H0|H0为真}=α,α为显著性水平。
第Ⅱ类错误一般叫做“取伪”错误:如果原假设H0不真时,错误地接受了H0,那么就犯了取伪错误,记为P{接受H0|H0不真}=β。
由于犯两类错误的概率不能同时控制变小,通常我们控制犯第Ⅰ类错误的概率,使它不超过a,这里所说的“显著性”是“显著性不合理”,是指只有当H0成立时,显著不合理的状态才拒绝H0,否则就要“接受”H0,这里的接受是指不拒绝H0,原因是由于没有获得充分的理由拒绝H0而勉强接受而已。
A2级压力容器制造证相关知识
A2级压力容器制造证相关知识
一、压力容器的定义:
平时我们所说的是固定式压力容器,要同时具备以下条件: (1)工作压力≥0.1MPa; (2)容积≥0.03m3并且内直径≥150mm; (3)盛装介质为气体、液化气体以及介质最高工作温度高 于或者等于其标准沸点的液体。
二、制造许可证的级别
A2级
拥有A2级即具备D级压力容器制造许可资格,压力 容器制造许可级别分为A、B、C、D四个级别。
三、制造许可证的品种范围
第Ⅲ类低、中压容器
1、压力容器按介质特性、设计压力和容积,分为Ⅰ、Ⅱ、Ⅲ类; 2、按设计压力分为低、中、高和超高压四个等级; 3、按用途分为反应、换热、分离和储存压力容器。

Fundamentals Level – Skills Module, Paper F5Performance Management December 2013 Answers 1(a)Incremental revenue Less VC Net profit/(loss)Further process?L(1,200 x 0·95 x $6·70)(1,200 x $0·5)$348Yes–(1,200 x $5·60) = $918x 0.95 =$(570)M(1,400 x 0·95 x $7·90)(1,400 x $0·70)$476Yes–(1,400 x $6·50) = $1,407x 0.95 = $(931)S(1,800 x 0·95 x $6·80)(1,800 x $0·80)$(720)No–(1,800 x $6·10) = $648x 0.95 =$(1,368)Process Co should further process L and M, since incremental revenue from further processing will exceed incremental costs.However, it should not further process S as incremental costs exceed incremental revenue in S’s case.Note:The above calculations could be done on a unit basis if preferred, still earning full marks.(b)The suggested transfer price being used is actual marginal cost. This means that whilst Division A would recover its variablecosts of producing products L and M, there is no profit margin built in and, therefore, unless Head Office intervenes and forces Division A to transfer L and M to Division B, Division A will not want to transfer these products. Also, Division A will not have the opportunity to recover any apportioned fixed costs since marginal cost does not include these. Not only would Division A not make any profit or recovery of apportioned fixed costs from the transfers using the suggested system, it would actually lower its overall profits if it were forced to transfer L and M for further processing rather than being allowed to sell them externally after the split-off point. Division A’s manager would feel extremely demotivated if he/she were to be made to transfer L and M for further processing, as it would make performance look poorer for the Division.All of the profit from both producing L and M and further processing them into LX and MX would be gained by Division B under the suggested system. If the criteria of return on investment (ROI) or residual income (RI) were then to be used to assess performance, as is usual for divisional performance assessment, Division B’s ROI/RI would be seen to have increased as a result of the further processing. Division B would then effectively be taking the credit for a large part of the work carried out by Division A. The manager of Division B would be unlikely to complain about this as it works in favour of his Division.Another point worth mentioning is that because actual cost would be used rather than standard cost, Division A would have little incentive to keep its variable costs down because it would pass all of its costs on to Division B. However, given that the suggested transfer price incorporates no profit for Division A, this point would hardly be arguable by Division B.If Division A were told to make the transfers to Division B, their autonomy would be taken away from them. This would be likely to have a detrimental effect on the motivation of managers since one of the primary purposes of creating a divisional structure is to grant autonomy.Note:Other points could be made too. A candidate would not be expected to make all of the above points in order to earn full marks.(c)Environmental management accountingInput/outflow analysisThis technique records material inflows and balances this with outflows on the basis that what comes in, must go out. So, if 100 kg of materials have been bought and only 80 kg of materials have been produced, for example, then the 20 kg difference must be accounted for in some way. It may be, for example, that 10% of it has been sold as scrap and 10% of it is waste. By accounting for outputs in this way, both in terms of physical quantities and, at the end of the process, in monetary terms too, businesses are forced to focus on environmental costs.Flow cost accountingThis technique uses not only material flows but also the organisational structure. It makes material flows transparent by looking at the physical quantities involved, their costs and their value. It divides the material flows into three categories: material, system and delivery, and disposal. The values and costs of each of these three flows are then calculated. The aim of flow cost accounting is to reduce the quantity of materials which, as well as having a positive effect on the environment, should have a positive effect on a business’s total costs in the long run.Activity-based costingABC allocates internal costs to cost centres and cost drivers on the basis of the activities which give rise to the costs. In an environmental accounting context, it distinguishes between environment-related costs, which can be attributed to joint cost centres, and environment-driven costs, which tend to be hidden in general overheads.Life cycle costingWithin the context of environmental accounting, life cycle costing is a technique which requires the full environmental consequences, and therefore costs, arising from production of a product to be taken account of across its whole life cycle,‘from cradle to grave’.Note:Only two techniques were required.2(a)Throughput accounting ratio = throughput return per factory hour/cost per factory hour.Cost per factory hourT otal factory costs/total available hours on bottleneck resource= $12,000,000/2,700 hours (12 x 5 x 50 x 90% hours)= $4,444·44Throughput return Large panels Small panels$$ Selling price12,6003,800Materials(4,300)(1,160)–––––––––––––Throughput per unit8,3002,640Hours per unit required on Machine M1·40·6Throughput return per hour$5,928·57$4,400Throughput accounting ratioThroughput return per factory hour/cost per factory hour:5,928·57/4,444·444,400/4,444·44= 1·33= 0·99 In any organisation, one would expect the throughput accounting ratio to be greater than 1. This means that the rate at which the organisation is generating cash from sales of this product is greater than the rate at which it is incurring costs. It follows on, then, that if the ratio is less than 1, changes need to be made quickly. Whilst the ratio for large panels is more than 1, it is just under 1 for small panels. However, if changes are made as suggested in (c) below, this could soon be rectified.(b)Optimum production planProduct No. of units Hours per unit Total hours T/P per hour Total T/PSmall panels 1,0000.6600$4,400$2,640,000(under contract)Large panels1,500(W.1) 1.42,100$5,928·57$12,449,997–––––––––––––––––––T otal2,700$15,089,997–––––––––––––––––––Less total factory costs($12,000,000)–––––––––––––Profit$3,089,997––––––––––––––––––––––––––W.1(2,700-600)/1.4(c)Increasing throughputGenerally speaking, throughput can be increased by increasing sales volumes or prices on the one hand, or by cutting costs on the other hand. In the case of S Co, it is not possible to increase sales prices as the company has guaranteed not to increase them for three years. From our answer to (b) above, we can see that S Co has unsatisfied demand for both small panels and large panels. There are customers out there who the company is unable to supply because of its restricted machine capacity. Therefore, it would be worthwhile for S Co to focus on increasing production volumes and thus sales volumes.In order to increase production volumes without making any additional capital expenditure, the company needs to focus on how it could increase the productivity of Machine M. We are told that there is plenty of spare capacity on Machines C andA. Some suggestions to increase Machine M’s capacity are as follows:–Machine M is currently only fully functional 90% of the time. This means that 300 hours of time are lost whilst the machine is being maintained or workers are not available to man it. If the maintenance work could be carried out outsidethe usual working day (i.e. either before 7 am or after 8 pm), some additional time could be freed up. This should bepossible given that we are told that the maintenance contractors work around the clock.–Workers could be trained to use more than one of the machines. This would then mean that, if some workers were absent, one of the other workers could step in and work on another machine in order to keep it running. Again, thiswould help to keep the lost 300 hours productive.–The most obvious machine time which is being lost is the one hour per day at lunchtime. This amounts to 250 lost production hours per year. These additional 250 hours could be used to produce an extra 178 large panels (250/1·4hours.) Large panels should be made first in preference to small panels since they generate a higher throughput permachine hour. If workers were trained to use all three machines then, if their lunchtimes were staggered, it may bepossible to keep machine M running for the whole working day. However, even after doing this, there would still be 590additional hours of time required on Machine M if the full market demand is going to be satisfied. Therefore, more timeneeds to be made available.–Finally then, in order to increase productive hours on M, the working hours of the factory would need to be increased.Either the working day could be made longer, given that workers must already be working shifts, or maybe the factorycould open for one extra day per week.3(a)Monthly costsMonth Cumulative Cumulative Cumulative Incremental Incremental Actual labournumber of average total number of total cost perbatches hours per hours batches hours month $batchJuly120020012002,400August (w.1)217635211521,824September4154·88619·522267·523,210·24October8136·2941,090·3524470·8325,649·60November (w.2)16124·41,990·368900·00810,800·096Working 1: Calculations for AugustCumulative average hours per batch: 200 x 0·88 = 176 hours.Cumulative total hours = 2 x 176 = 352 hours.Incremental number of batches = cumulative no. of 2 batches for August less cumulative number of 1 batch for July =1 batch.Incremental total hours = cumulative total hours of 352 for August –200 for July = 152 hours.Actual labour cost = incremental total hours of 152 x $12 per hour = $1,824.Working 2Time for 7th batch:Y = ax b= 200 x 7–0·1844245= 139·693 hours.T otal time for 7 batches = 139·693 x 7 = 977·851 hours.T otal time for 8 batches = 1,090·352 hours.Therefore 8th batch took 112·501 hours (1,090·352 –977·851)Time for batches 9–16 = 112·501 x 8 = 900·008 hours.Therefore cumulative average time for batches 1–16 = 1,090·352 + 900·008 = 1,990·36 hours.Cumulative average time for 16 batches = 1,990·36/16 = 124·4 hours per batch.Note:The labour costs for November could be arrived at quickly simply by taking the 112·501 hours for the 8th batch, multiplying it by 8 batches and applying this number to the $12 per hour labour cost. This quick calculation is totally sufficient to earn full marks.(b)Implications of end of learning periodThe learning period ended at the end of October. This means that from November onwards the time taken to produce each batch of microphones is constant. Therefore, in future, when Mic Co makes decisions about allocating its resources and costing the microphones, it should base these decisions on the time taken to produce the 8th batch. The resource allocations and cost data prepared for the last six months will have been inaccurate since they were based on a standard time per batch of 200 hours.Mic Co could try to improve its production process so that the learning period could be extended. It may be able to do this by increasing the level of staff training provided. Alternatively, it could try and motivate staff to work harder through payment of bonuses, although the quality of production needs to be maintained.(c)Involving senior staff at Mic Co in the budget setting processAdvantages–Since they are based on information from staff who are most familiar with the department, they are more likely to improve the accuracy of the budget. In Mic Co’s case, the selling price could have been set more accurately and salesmay have been higher if the production manager had been consulted.–Staff are more likely to be motivated to achieve any targets as it is ‘their’ budget and they therefore have a sense of ownership and commitment. The production manager at Mic Co seems resigned to the fact that he is not consulted onbudgetary matters.–Morale amongst staff is likely to improve as they feel that their experience and opinions are valued.–Knowledge from a spread of several levels of management is pooled.–Co-ordination is improved due to the number of departments involved in the budget setting process.Disadvantages–The whole budgeting process is more time consuming and therefore costly.–The budgeting process may have to be started earlier than a non-participative budget would need to start because of the length of time it takes to complete the process.–Managers may try to introduce budgetary slack, i.e. making the budget easy to achieve so that they receive any budget-based incentives.–Disagreements may occur between the staff involved, which may cause delays and dissatisfaction. In Mic Co’s case, however, the fact that the production manager was not consulted has led to disagreement after the event.–Can support ‘empire building’ by subordinates.4Ratio analysisDivision S Division CYear on year Year on year Increase in revenue44%9%Increase in material costs36%25%Increase in payroll costs70%15%Increase in property costs78%6%GPM in 201356%65%GPM in 201261%67%Increase in D & M costs38%18%Increase in admin costs6%0%NPM in 201311%21%NPM in 20129%22%Revenue per employee in 2013$102,224$104,917Revenue per employee in 2012$111,772$104,828Payroll cost per employee in 2013$27,000$21,000Payroll cost per employee in 2012$25,020$20,000T otal market size ($ revenue) in 2013 (w.1)$129·48m$80·12mT otal market size ($ revenue) in 2012 (w.1)$107·75m$77·61mWorking 1 for market sizeDivision S 2013: $38,845m/30% = $129·48m Division C 2013: $44,065m/55% = $80·12mDivision S 2012: $26,937/25% = $107·75m Division C 2012: $40,359m/52% = $77·61mNote:Percentages have been calculated to the nearest 1%.CommentaryGeneral overviewOverall, Division S has performed well in 2013, although it has not managed to meet its objective of becoming market leader despite its $2m advertising campaign. Since it has 30% of the market in 2013 and there are only two competitors holding 70% of the market between them, at least one of those competitors must hold 35% or more of the market.Revenue and market shareThis has increased by a huge 44% in the last year. This compares to an increase of only 9% in Division C. However, part of the reason that this has been achieved is because the changes in fire safety laws introduced by the government at the end of 2012 have caused the market for fire products and services to increase from $107·75m to $129·48m. Part of Division S’s success is therefore down to increased opportunity. However, Division S has also increased its market share by a further 5 percentage points compared to 2012. Division C has only managed a 3 percentage point increase in its market share, so this is a good result by Division S. One can assume that this is at least partly as a result of the advertising campaign carried out by Division S. However, this did cost a large amount, $2m, and it did not quite enable the Division to achieve its aim of becoming market leader.Materials costsThe increase in materials costs is 36%, compared to an increase in revenue of 44%. It is difficult to say whether this is good or bad since the increase in revenue includes revenue from services, for which no materials costs would be expected to arise. Further information is needed on the split of revenue between products and services.Payroll costs, revenue per employee and cost per employeePayroll costs have increased by a massive 70% and far more than Division C’s 15% increase. This is largely due to the fact that Division S’s employee numbers increased from 241 in 2012 to 380 in 2013. This is a really big increase in employee numbers and has been accompanied by a fall in revenue per employee from $111,772 in 2012 to $102,224 in 2013. It is possible that Division S over-recruited as it hoped to secure a greater level of business than it did through its advertising campaign. Division S’s payroll cost per employee also increased from $25,020 in 2012 to $27,000 in 2013. Presumably, this is because of the fact that there is high demand for staff skilled in this area and Division S has probably had to increase pay in order to attract the calibre of staff which it needs.Increase in property costsIn percentage terms, the biggest increase in costs which Division S has suffered is in relation to its property costs. They have increased by 78%, compared to Division C’s 6% increase. It would appear that this increase is due to the increased rent charged by Division S’s landlords on its business premises, which in turn has risen because of the increased tax charges. However, it is not possible to quantify this precisely without further information on rent increases.Gross profit marginThis has actually fallen from 61% to 56%. Division C has also seen a fall in its GPM, but only a 2 percentage point fall as opposed to Division S’s 5 percentage point fall. The reasons for Division S’s lower GPM are the higher material, payroll and property costs.Also, Division S did not try to pass on any of its increased costs to its customers in the form of higher prices.Distribution and marketing costsThese have increased by 38% compared to Division C’s 18%. However, when you take out the advertising costs in both years’figures and work out the cost increase without them ($8·522m –$7·102m/$7·102m), it leaves an increase of only 20%. This increase would be expected given the 20% increase in world fuel prices which occurred. Division S has to deliver to a wider geographical spread of customers than Division C, so it would be expected to feel the full brunt of fuel price increases.Administrative costsThese have increased by 6% compared to Division C’s less than 1% increase (0% when rounded down to the nearest percent).Further information is needed about the items included in these cost figures to explain why this increase has arisen.Net profit marginDespite challenging cost increases in all categories, Division S has still managed to increase its NPM from 9% to 11%. However, this is substantially lower than the NPM in Division C, which has fallen slightly but is still 21%, almost twice that in Division S.As we have seen, Division S’s GPM is lower than Division C’s anyway and, on top of that, Division C has not suffered a big increase in advertising costs like Division S; nor have administrative costs risen inexplicably.Head OfficeThere is no information given about Head Office. If the Calana Division is also the Head Office, there could be Head Office costs included in Calana’s figures, which would affect the comparisons being made. Further information is required here.5(a)Planning and operational variances(i)Material Price Planning Variance (MPPV) (Standard price –revised price) x actual quantitySheets($5 –$6) x 248,000 = $248,000 adversePillow cases($5 –$6) x 95,000 = $95,000 adverseT otal$343,000 adverse(ii)Material Price Operational Variance (MPOV)(Revised price –actual price) x actual quantity Sheets($6 –$5·80) x 248,000 = $49,600 favourablePillow cases($6 –$5·80) x 95,000 = $19,000 favourableT otal$68,600 favourable(iii)Material Usage Planning Variance (MUPV)(Standard quantity for actual production – revised quantityfor actual production) x standard priceRQ for each pillow case = 0·5 m x 1·1 = 0·55 mSheets(240,000 –240,000) x $5 = 0Pillow cases(90,000 – 99,000) x $5 = $45,000 adverseT otal$45,000 adverse(iv)Material Usage Operational Variance (MUOV)(Actual quantity – revised quantity for actual production) xstandard priceSheets(248,000 –240,000) x $5 = $40,000 adversePillow cases(95,000 – 99,000) x $5 = $20,000 favourableT otal$20,000 adverseNote:The MPPV could be calculated using the revised quantity rather than the actual quantity. Similarly, the MUOV could be calculated using the revised price rather than the standard price. Marks will be given where this alternative method is used instead. However, it should be used for both the MPPV and the MUOV, otherwise the figures cannot be reconciled back to the difference between actual spend and the budget for spend as flexed for actual production levels ($339,400 adverse).(b)Performance of the production managerIn total, there has been an overspend of $339,400, which looks poor. However, when the reasons for this are examined, together with the variances calculated in (a), it is apparent that the production manager cannot be held solely responsible for the overspend. In fact, he has had little control over the situation.Increase in cotton priceSince cotton is used to make bed sheets and the price of this rose in the world market by 20%, the production manager’s performance has to be looked at in light of this. Because of the increased market price, the adverse material price planning variance is very high, since the budgeted cost of $5 per m2was far below the actual market price of $6 per m2. The production manager cannot be held responsible for this since he does not set the standard costs. He can only be held responsible for any difference in price between the $6 market price and the $5·80 actual price paid. Since the $5·80 paid per m2is less than the market price of $6 per m2, the manager performed well, as shown by the favourable material price operating variance of $68,600.Increase in amount of cotton usedSince more cotton was used for actual production than budgeted, a total adverse material usage variance of $65,000 ($45,000 + $20,000) arose. However, of this, $45,000 (material usage planning variance) arose because of the request for a change in the design of the pillowcases by Bedco’s customer. This was not within the control of the production manager and his performance should not therefore be assessed on it. However, an adverse material usage operational variance of $20,000 also arose; the performance of the production manager is weak here. Most of the adverse operational variance actually related to the production of bed sheets rather than pillowcases. It is not clear why this arose but it is definitely poor. Bedco was also unable to produce all the pillowcases ordered by its customer in November as the order fell short by 10,000 units. If this was genuinely because of the late design change, however, it seems unfair to judge the production manager on this.Fundamentals Level – Skills Module, Paper F5Performance Management December 2013 Marking SchemeMarks1(a)Further processingL3M3S3Conclusion1–––10–––(b)IssuesPer valid point – maximum2–––Maximum5–––(c)Environmental accountingEach description – maximum3–––Maximum5–––Total marks20––––––2(a)Throughput accounting ratiosCost per factory hour2Throughput per unit for large panels1Throughput per unit for small panels1Throughput per hour for large panels1Throughput per hour for small panels1TAR for large panels0·5TAR for small panels0·5Discussion of TAR2–––9–––(b)Optimum production planOptimum number of large panels1Optimum number of small panels1T otal throughput1Less total factory costs1Profit1–––5–––(c)Increasing productivityEach suggestion 2–––Maximum6–––Total marks20––––––Marks 3(a)Monthly costsPer monthly cost: July–October1·5November3–––9–––(b)End of learning periodEach point discussed – maximum2–––Maximum4–––(c)Advantages and disadvantagesEach advantage1Each disadvantage 1–––Maximum7–––Total marks20––––––40·5 marks per calculation7 Per valid piece of further information –max 20·5 Per comment – maximum2–––Total marks20––––––5(a)Variance calculationsMPPV3MPOV3MUPV3MUOV3–––12–––(b)DiscussionEach valid point2–––Maximum8–––Total marks20––––––。
