Selection is based on the follow criteria: For high EMIshielding requirements 100 or 80 OPI mesh is the desirable choice forsuperior shielding. If higher light transmission is desired, conductivecoatings are a suitable solution. Both mesh and conductive coatingoptions provide excellent clarity and maintain sharp image fi delity.Typical sheet resistances are 4 and 8 ohms/sq. 4 ohms/sq has higherEMI shielding than 8 ohms/sq (see shielding curve). Other sheetresistances (ohms/sq) are available upon request.20406080100120000,300303ShieldingEffectiveness(dB)Frequency (MHz)Shielding Effectiveness100 OPI Blackened Stainless Steel100 OPI Blackened Copper80 OPI Blackened Stainless Steel50 OPI Blackened Stainless Steel4 ohms/sq ConducƟve Film8 ohms/sq ConducƟve FilmIEEE 299 Open ReferenceCoating DesignOptimized for visible light (400-700 nm)Average Refl ection < 0.7%Clear Hardcoating CoatingClear hardcoating is an ideal choice when a clear scratch resistant window is desired.

USP40 781 比旋度
〈781〉 OPTICAL ROTATIONINTRODUCTIONMany pharmaceutical substances are optically active in the sense that they rotate an incident plane of polarized light so that the transmitted light emerges at a measurable angle to the plane of the incident light. This property is characteristic of some crystals and of many pharmaceutical liquids or solutions of solids. Where the property is possessed by a liquid or by a solute in solution, it is generally the result of the presence of one or more asymmetric centers, usually a carbon atom with four different substituents. The number of optical isomers is 2n , where n is the number of asymmetric centers. Polarimetry, the measurement of optical rotation, of a pharmaceutical article may be the only convenient means for distinguishing optically active isomers from each other and thus is an important criterion of identity and purity.许多药物具有光学活性,因为它们转动偏振光的入射面,使透射光以可测量的角度出现在入射光的平面上。

常用比喻词like,as, as if, as though等,补充:二、隐喻(metaphor)这种比喻不通过比喻词进行,而是直接将用事物当作乙事物来描写,甲乙两事物之间的联系和相似之处是暗含的。
补充:三、提喻(synecdoche)又称举隅法,主要特点是局部代表全体,或以全体喻指部分,或以抽象代具体,或以具体代抽象。
四、拟人(personification)这种修辞方法是把人类的特点、特性加于外界事物之上,使之人格化,以物拟人,以达到彼此交融,合二为一。
五、夸张(hyperbole)这是运用丰富的想象,过激的言词,渲染和装饰客观事物,以达到强调的效果.六、叠言(rhetorical repetition)这种修辞法是指在特定的语境中,将相同的结构,相同意义词组成句子重叠使用,以增强语气和力量。
七、借代(metonymy)是指两种不同事物并不相似,但又密不可分,因而常用其中一种事物名称代替另一种。
八、双关语(pun)是以一个词或词组,用巧妙的办法同时把互不关联的两种含义结合起来,以取得一种诙谐有趣的效果。
九、拟声(onomatcpocia)是摹仿自然界中非语言的声音,其发音和所描写的事物的声音很相似,使语言显得生动,富有表现力. 十、讽刺(irony)是指用含蓄的褒义词语来表示其反面的意义,从而达到使本义更加幽默,更加讽刺的效果.十一、通感(synesthesia)是指在某个感官所产生的感觉,转到另一个感官的心理感受。
十二、头韵法(alliteration)在文句中有两个以上连结在一起的词或词组,其开头的音节有同样的字母或声音,以增强语言的节奏感。

无线通信中的低功耗维特比译码器设计
无线通信中的低功耗维特比译码器设计朱坤顺;杨红官;樊晓华;乔树山【摘要】针对无线通信中低功耗维特比译码器设计结构复杂的问题,提出一种四级流水串并结合的(2,1,9)低功耗维特比译码器。
该译码器采用改进的加-比-选( ACS)单元,以降低硬件复杂度,在提高时钟运行速率的基础上减少运行功耗。
幸存路径存储单元采用改进的路径相消方法,减少译码器的输出延迟,提高译码效率。
性能分析结果表明,基于TSMC 0.18μm CMOS逻辑工艺,在1.62 V,125℃操作环境下,该译码器数据最大速度为50 MHz,自动布局布线后的译码器芯片面积约为0.212 mm2,功耗约为23.9 mW。
%Toward the complicated structure of low power implementation of the Viterbi decoder in wireless communication,a low power (2,1,9) Viterbi decoder with the structure of series and parallel combination in four-level pipeline is proposed in the paper. To increase working rate, with the consideration of the implementation hardware complexity,a modified Add-compare-select( ACS) unit is used to satisfy its low power decoding requirment. In order to increase the efficiency of decoding and decrease the latency of decoder,a method of path mutual eliminating is employed in the design. Implemented by TSMC 0. 18 μm standard CMOS technology under 1. 62 V and 125 ℃,and analysed with placement and route,the chip’ s highest speed is about 50 MHz,the area is 0. 212 mm2 ,and the power comsumption is 23. 9 mW.【期刊名称】《计算机工程》【年(卷),期】2014(000)010【总页数】4页(P114-117)【关键词】维特比译码器;低功耗;加-比-选;路径度量存储;路径相消;幸存路径【作者】朱坤顺;杨红官;樊晓华;乔树山【作者单位】湖南大学物理与微电子科学学院,长沙410082;湖南大学物理与微电子科学学院,长沙410082;中国科学院微电子研究所,北京100020;中国科学院微电子研究所,北京100020【正文语种】中文【中图分类】TH166在无线通信中,数据的传输过程总会受到各种噪声和电磁的干扰,使得接收到的信息有一些错误的传输。

电力线通信 (PLC) 利用现有电力线基础设施,为在许多工业应用引进智能监控和控制提供了经济高效的方法。
它让 PLC 成为用于智能电网应用(如智能抄表、照明控制、太阳能、插入式电动车以及家庭和楼宇中的供暖、空调和安全系统)的首选技术之一。
对这些应用实施低频窄带 PLC (LF NB PLC) 技术将提供最适合的带宽、功耗和成本要求。
在窄带域(频率高达 500kHz)运行可确保数据完整性,同时可将系统成本降到最低。
数据速率从 1.2kbps 到数百 kbps 不等,具体取决于现有标准。
开发高效 PLC 实施也会遇到困难。
电力线本身就具有噪声,因此需要强大架构才能确保数据可靠性。
此外,每种应用和工作环境都不同,需要开发人员针对各种因素优化设计。
由于协议标准和调制方案多种多样,开发人员需要灵活的开发平台,以简化设计、实现对环境条件的优化、遵守当地法规的同时可轻松调整以满足不断发展的标准。
电力线通信调制解调器系统的调制信号首先进入接收器级或有源带通滤波器,其中为滤波器选择的运算放大器应该提供低噪声、低谐波失真和低输入偏置(如 TI 的 OPA365 或 OPA353 中所示)。
使用可编程增益放大器 (PGA)(如 PGA112)调节接收信号时,可实现宽动态范围和优化信号处理。
它需要足够快速准确地连接至模数转换器的输入,以便正确转换为数字形式供处理。
这可通过 F28235 Delfino? 或F2802x/03x Piccolo? 微处理器(可升级 C2000? 32 位微处理器 (MCU) 系列的成员)的片上 12 位 ADC 来实现。

• Legal immigrants make up only 2.4% of recipients
(Georgia Department of Human Resources 2000)
• A significant amount of TANF funds is spent on transition-into-work programs, most of which immigrants do not use
The Original Proposition 187
• 1.6 million undocumented immigrants in California in 1994
• Pre-187, undocumented immigrants ineligible for welfare but could get emergency and pre-natal health services
(Health Policy Tracking Service 1998)
Undocumented Immigrants DO Pay Taxes
• Undocumented immigrants pay 46% as many taxes as natives, and receive only 38% of benefits (Cato Institute 1995) • Immigrants pay $70.3 billion a year in taxes and receive $42.9 billion in services (Urban Institute) • Undocumented immigrants are still subject to payroll deductions and income taxes, thus supporting Unemployment Insurance and Social Security even though they are ineligible for these services (Urban Institute 1990)
Theoretical Considerations
• Citizenship
• Migration theory
• Goals of democratic government
Historical Context
• California Proposition 187
• PRWORA: Personal Responsibilities and Work Opportunity Reconciliation Act
The Criteria are UNFAIR
• The welfare law of 1996 cut $24 billion in benefits to legal immigrants and refugees
(National Conference of State Legislatures, Immigrant Policy Project 2001)
Welfare Eligibility
Should undocumented immigrants be eligible for TANF assistance?
YES: Maria Conejero, a single undocumented immigrant mother with two children (one a citizen, one not a citizen) NO: Aaron Catrett, a working US citizen taxpayer
• Costs? Save $200 million, spend $100 million, lose $15 billion?

• Federal 5 year bars • End of SSI and Food Stamps for immigrants • Medicaid and TANF for immigrants? • Sponsors and deeming
Zimmermann & Tumlin. Patchwork Policies: State Assistance for Immigrants Under Welfare Reform /urlprint.cfm?ID=5985 April 1, 1999.
Welfare Reform (PRWORA)
• New Federalism: Devolution and state control • Undocumented immigrant exclusion • The pre/post divide
• Qualified and Unqualified immigrants
Proposition 781
Should Undocumented Immigrants Have Access to Public Assistance?
Perfectville, California Town Council Meeting Wednesday March 27, 2003 3:30pm
Undocumented Immigrants SHOULD be eligible for TANF
• In the best interests of the program • Undocumented immigrant do not use TANF as much as natives • Current criteria are unfair • Undocumented immigrants pay taxes • Not giving TANF to undocumented immigrants would contradict the Constitution
Denying Access DOES Contradict the Constitution
• Graham vs. Richardson • Mathews vs. Diaz • Other conflicts with US & state Constitutions (all from National Conference of State Legislatures, Immigrant Policy Project 2001)
Which Immigrants are Eligible for TANF?
• Illegal immigrants, family unity immigrants and temporary agricultural workers are NOT eligible for TANF (Health Policy Tracking Service 1998) • Lawful permanent residents, refugees, asylees, those granted parole for more than one year, those whose deportation has been withheld, conditional entrants before 1980, Cuban-Haitian entrants, and certain victims of domestic violence ARE eligible for TANF (Health Policy Tracking Service 1998)
Undocumented Immigrants SHOULD NOT be eligible for TANF
Immigrants Do NOT Use Services as Much as Natives
• Hispanics, which make up the largest percentage of immigrants, are only 1.3% of TANF recipients
(Georgia Department of Human Resources 2000)
The Agenda
• Background information
•Welfare eligibes
• SSI and Food Stamps • Final thoughts
• Questions to town members in attendance
Including Undocumented Immigrants IS in the Best Interests of the Program
• States get a $100 million/year bonus for reducing abortion & out-of-wedlock births, which are lower among undocumented immigrant families (US Department of Health & Human Services, Administration for Children & Families, 2003) • States must meet standard of 40% of TANF families working 30hr/week, while current rate is only 9%. Adding undocumented immigrants would boost this level. (National Conference of State Legislatures, Immigrant Policy Project 2001) • The goals of TANF are to ―promote job preparation, work, and marriage,‖ of which immigrants, even undocumented ones, have a higher level than natives of the same economic bracket
