国外博士毕业论文范文精选3篇(全文)

国外博士毕业论文范文精选3篇博士的开题报告一般需要多少字?怎样写才比较规范呢?博士生开题报告的写法1、博士论文要有原创性知识;2、博士论文开题报告不是回答是什么的问题，而是回答为什么的问题;3、博士论文开题要确定用什么样的知识来回答提出的问题。

这些知识应该是多学科的知识(cross-discipinry inquiry)。

方法论包括两种：理论框架和技术性、技巧方法。

开题报告不能简单排列，只要做到同类项归类。

另外，文献索引要规范，譬如可以采纳按照拼音的顺序排列。

论文开题是语境、语汇、逻辑和方法的统一体，开题是寻找一个合适的语境，用合适的语汇，以合理的逻辑，并论证方法的合理性。

开题报告是一个过程，早点开始，不断去梳理。

开题之前是决策，是选择，很痛苦(如何寻找人生的另一半，很费心思);开题之后要硬着头皮坚持，总会发现精彩之处(找到了之后就好好过日子，会找到属于两个人的精彩的)。

开题中应注意的几个问题：(1)对开题性质的认识。

开题是一个重要环节，功能是制定研究计划。

开题报告是由博士生对博士论文研究报告的价值性和可行性的一个辩论文本。

(2)选题。

选题要有挑战性，理论性和可行性(fesible)。

题目是研究出来的，不是给定的。

问题有problem, question和issue三类。

(3)文献综述。

综述是指综合评述，是对知识的梳理。

综述文献不是做相关领域的文献，那些不能证明问题，而是on??，of??的文献。

另外，不能对文献有偏见，也不能出现很少有人研究，没人进行研究的语句。

4、开题报告的撰写时间至少需要一年。

开题报告格式与开题报告写作技巧开题报告是研究生毕业论文工作的重要环节，是指为阐述、审核和确定毕业论文题目而做的专题书面报告，它是研究生实施毕业论文课题研究的前瞻性计划和依据，是监督和保证论文质量的重要措施，同时也是训练研究生科研能力与学术作品撰写能力的有效的实践活动。

《ZG青年报》报道:复旦大学新闻学院20XX级研究生所做毕业论文开题报告，仅有不到1/3的博士研究生获一次性通过，而78位硕士研究生，10人没获通过，仅有19人获一次性通过。

Global Positioning System Automatic V ehicle Location SystemBill J. Papatheofanis, Marvin L. Hasenack, Robert T. Teller,and Gerald F. RamseyAbstractLos Alamos National Laboratory (LANL) is a unique facility covering over 43 square miles. The Emergency Management and Response Office (EM&R) is required to respond, provide Incident Command(IC), and coordination for all Laboratory emergencies. This requires IC’s and support staffto respond to the actual scene of the incident. Since the IC is under numerous constraints and stress, the office wanted the capability of locating the EM&R vehicles on an electronic map. An automated vehicle location (AVL) system was required for the additional safety of the emergency response personal. The requirements for the AVL system include total automatic tracking and low cost. Mer carefkl consideration, it was determined that the most efficient and cost effective system would be based on packet radio technology as the transmission media. The location is determined by the Department of Defense Global Positioning System (GPS) communicate with each other. The first component was a GPS receiver which actually provides the location information, equipped with a digital hte- to communicate location information remotely. The second component is a modem that interfaces the GPS digital interface information to a radio. The third component is the radio itself which allows for the actual information transfer from the remote GPS receiver and modem. The fourth component is the software package that provides moving maps and displays the vehicle location on that map for the AVL application. This paper describes the steps taken in the integration of the equipment into the AVL package.1. IntroductionLos Alamos National Laboratory (LANL) is a unique facility covering over 43 square miles. The Emergency Management and Response (EWR) office has the overall responsibility for coping with and mitigating the effects of any emergency at LANL. The EM&R office supplies an Incident Command (IC) which responds to all laboratory emergencies. This requires the IC and support staff to respond to the actual scene of an incident. The EMBER office wanted the capability of locating their vehicles on an electronic map because of the lack of markings on facilities, unmarked secondary roads, unmarked trails, and the lack of marked terrain fames. This automated location system would provide the additional safety for the IC's in cases where something adverse happens to the responders. Many times the EM&R IC is required to respond to a scene at night or during adverse weather conditions. With the automatic location system the IC can be directed to the scene even if land features are not availabb. The vehicle can also be located if the responderis incapacitated for any reason. Position System (GPS). The satellite based GPS system provides information to special receivers which collect data from several satellites and are then processed by a built in navigational computer. The GPS receiver then displays its location to within 100 feet in a selectable coordinate system. In addition to providing x-y coordinates the receiver calculates altitude, speed, direction of travel, date and time.The simplest method of vehicle tracking using GPS would be to install a receiver in a vehicle, and using a two-way radio, transmit the displayed Coordinates to a dispatcher who can take the received coordinates and mandy plot them on a paper map. Today's technologyenables this process to be totally automated. This paper discusses how to put together a totally automated system using commercial off-theshelf equipment.The automatic vehicle location (AVL) system is based on the Department of Defense Global2. EM&R VehiclesEM&R has two response vehicles which are equipped with AVL. Figure 1 is a photo of the 1994 Chevrolet Suburban which is the primary response vehicle. Figure 2 is a photo of the 1994 Jeep Cherokee which is the back-up vehicle that provides field support for the primary vehicle. Both vehicles cany numerous radios and cellular telephone for communications with the Emergency Operations Center (EOC)and multi agencies which respond to emergencies at LANL. The vehicles also carry documentation on Laboratory information required for the IC’s to carry out their function.3. Vehicle AVL PackageThe vehicle AVL package consists of three components. The first is the GPS unit, the second is the modem, and the third is the radio. Zn this section we will describe each component, the required specifications, and which manufacture’s equipment was u sed (see Appendix 1 for addresses and phone numbers).A. The GPS unit used is a Trimble Scout Master which met all the foxlowing requirements:1. External Antenna - The GPS receiver requkes an outdde remote antenna to work properly when mounted inside a vehicle.2. External Power - The GPS receiver should have external power capabdity. This allows the unit to get power directly from the vehicle and also provides a way of controlling when the receiver is powered on and off.3. Serial Port - This allow the GPS receiver to communicate its position information with an external device via RS-232.4. NEMA 183 Protocol - The output of the GPS receiver’s serial port is programmable for various standard and proprietary protocols. NEMA 183 is the National Electrical Marine Associations 183 standard protocol which has become a standard in the GPS world. Most commercial mapping SaRWare recognizes the NEMA I83 protocol as well as do most radio modems.B. The radio modem used is a Kantronics WM1200 packet radio modem. Thismodem met all of the following requirements:1. Packet Radio Standard AX.25 Protocol - This protocol provides a standardtransmission method which is specifically written for radio networking and provides error correction.2. Radio Interface - This modem is specifically manufactured to be connected to a radio.3. GPS Ready - The wM1200 has built-in software specifically written tointerpret NEMA 183 sentences from a G PS receiver and then broadcast them over theradio.4. Unique Identification - Each modem has a unique programmable identifkation callsign. The call sign allows each vehicle to have a unique address.5. Programmable Reporting - The modem allows the user to program vehicle reporting intervals allowing the system optimization.C. The radio used was a Motorola Maxtrac 300. This radio was selected because of the following features:1. External programmable interface - The Motorola Maxtrac 300 radio has a 16 pin external programmable interface. This interface is programmable through the radios programming software which allows the user to program the functionality of each pin onthe 16 pin connector. This feature allows the modem to interface with the correct internal radio circuits to hction most efficiently. This also allows for all the wiring to beexternal to the radio: no wires hang out from the inside of the radio that could provide interference paths to the radio and the modem.2. Multiple encodeldecode capability - The Motorola Maxtrac 300 is capable of generating and detecting all standard coded squelch signaling. This allows the radio toprovide the necessary signaling to access the repeater. This also allows the same radio channel to be used for both data and voice without the two modes interfering with each other.4. RepeaterThe LANL system required a repeater for reliable coverage over the 43 square mile complex and additional areas outside the Laboratory. The repeater is required due to the propagation o f V ” F radio being limited to line of sight. As LANL, terrain varies fiom mountain top to canyon bottom, the repeater was located on top of Pajarito Mountain which overlooks most of the Laboratory. The repeater is a Motorola Quanta Repeater which is a standard repeater station. The standard voice repeater was chosen over a digital repeater to avoid the hidden station problem. Digital repeaters rely on store forward technology which allows the repeater to transmit and receive on a single fiequency. The digital repeater does not retransmit received signal simultaneously. It actually receives data, stores the data in a buffer, and then transmits the data from the buffer. The store forward repeater can hear all the stations on the network, but they cannot hear each other. The hidden station problem occurs when all the stations cannot hear each other, allowing multiple stations to try to transmit at the same time causiig interference.5. Base StationThe base station is located at the EOC and consists of four components. The first two are the same 85 in the vehicle paw: the radio and the modem. The third component is a computer which is capable of running the software to interpret the received data and display that data on a map. The computer for this installation is an IBM PC. The fourth component is the software itself. The software package that we have implemented on the system is from ERM. ERM software is specifically written to interpret NEMA 183 sentences anddisplay this hfbrmation an a moving map. The ERN sohare is very sophisticated and provides not only location information but is capable of displaying and recording multiple vehicle’s positions at the same time.6. Vehicle ConfigurationThe equipment was selected and initial tests were performed on the bench. When it was time to integrate the components into a vehicular package, the first attempt was under the premise that the vehicle users should have access to the GPS unit so that they know their position information as well as the same equipment peiforming the AVL bction. This did work for a short period of time, however, problems with the AVL started to OCCUT which were traced back to the GPS unit being set to erroneous parameters. Everyone that saw the GFS unit in the vehicle had to press all the buttons which placed the Unit in an unusable operating state. At that point, we decided that the system should operate autonoumsly and the equipment should be packaged in a “Black Box” without any user selectable options. Figure 3 is an assembleThe next issue was where to put the boxes in both of the vehicles so that they w ere protected from daily vehicle use. In the Suburban, the “Black BOX” was located underneath the pull out drawer that is in the cargo campartanent of the vehicle (see Figure 5). In the Jeep, the “Black Box” was mounted in the rear cargo compartment next to one of the other radios (see Figure 6).iagram of the “BIack Box”. Figure 4 is a photo of the inside of one of the actual boxes.The other problem that we encountered was where to mount the GPS antennas on the vehicles. The antennas that came with the GPS units were intended to be temporarily mounted using a built in magnetic base. The units also came with a mast mount which is great for mounting the antenna on a boat mast. The mast mount adapter mounted to the bottom of the antenna with four screws. The four screw mount was used to mount the antennas on top of the emergency fight bar on each vehicle. Figure 7 is a photo of the antenna mounted on one of the light bars.9. ConclusionThe system described in this paper is in operation today and is providing location information to LANL”s EM&R EOC. The two emergency vehicles have been in operation for two months and continue to operate without any problems. This project met all of the requirements for a low cost reliable AVL system.10.

ACCA-OBU怎么找导师？怎么写论文？

ACCA-OBU怎么找导师？怎么写论文？对于ACCA考试来说，每个ACCA考生有机会通过提交论文和商业分析报告获得ACCA-OBU海外学士学位。

也就是说，学习ACCA不但可以收获扎实的财会理论基础和思维，还能够收获海外学历，这也就意味着，如果你在大学的时候就学习ACCA，如果通过速度够快够顺利，那么可以在毕业时拿到国内国外双证双学位，还不太清楚ACCA-OBU是什么，戳：ACCA-OBU也并不是每个学生都有机会可以获得ACCA-OBU海外学历的，那么有哪些条件呢？你还不太清楚，戳：ACCA-OBU学位申请条件在成功申请后，很多同学就要开始头疼自己的论文了，国内的论文尚且都要改多次，更别说用英文写全文了，真的有的无从下手，那么你需要论文导师的指导来帮助你不如英文论文书写的第一关。

导师会如何指导ACCA-OBU海外学位论文呢？1.首先, 导师需要给学生讲解一下论文的选题,内容等,让学员对论文的要求有个基本介绍. 当然, information pack 里的内容介绍的已经很详细了，需要让学员仔细阅读information pack. 同时，要让学员对自己完成论文的进度做一个估算。

2. 其次，充分利用学员跟导师的见面。

牛津布鲁斯大学要求导师在OBU的辅导中需要跟学生有3次见面，每次半小时。

但学员的水平各异，对于基础差的学员，我可能要辅导更多次，甚至10次。

方式也可以多样化，比如：电邮，电话，微信，聊天工具等。

每次的辅导过程都要充分利用，提前阅读好学员论文，要对学员的写作问题提出建议，但导师只是起到辅助的作用，导师不能代替学员写。

3.最后，要利用好presentation的时间。

根据要求，学员在第3次见面时需要给导师做个15分钟presentation. 导师要让学员充分准备这个，因为通过presentation,学员能自己意识到自己论文中的问题，并且可以利用这个机会，能跟导师进一步讨论论文的内容。

其次，让我们一起来看看国内同学在写ACCA-OBU海外学位申请过程的论文普遍出现的一些问题：对国外论文格式要求不了解多数同学都是第一次写英文论文，甚至第一次写论文，并不了解它的格式和要求。

Do not include the name of your school, advisor, or teammembers on this page.A New Type of Toll Plaza Based on Bionics-HoneycombSummaryIn this paper, we analyze the performance of commonly used toll plaza basedon our proposed mathematical model. A new improved toll plaza is proposed toreduce the cost, decrease the probability of collision at the merging point andincrease the throughput.The distribution of our proposed tollbooths resembles the honeycomb. At thecenter of each regular hexagonal honeycomb, there are two tollbooths, whichserve two separated vehicle streams. The vehicles in these two separated streamsare merged in advance before they continue their journey on the highway. Due tothe specific pattern of the new toll plaza, the total area can be reducedsignificantly. Meanwhile, the average wasted time caused by queuing can bediminished, which means that the throughput will be raised. Additionally, bysplitting the merging procedure into two stages, the possibility of accidentscan also be decreased.The main contributions of this paper are as follows:(1) The new designed cellular architecture can greatly reduce theconstruction area compared with traditional linear distributed toll gates.(2) We analyze the throughput of toll plazas by means of the queuingtheory. To verify our theory, we simulate the behavior of the large number ofvehicles passing the toll plaza with the help of PTV- VISSIM. Simulation resultsshow that the ideal cellular distributed toll booths have better resultscompared with traditional toll stations, especially when the traffic flow isheavy, the average travel time reduced by about 55% and the average delay timeof each lane is reduced by about 70%.(3) W e analyze the influence of the proportions of different types oftollbooths to our design. According to relevant documents, the impact of exact-change tollbooths is similar to manual tollbooths, so we only consider two kindsof tollbooths: human-staffed tollbooths and E-ZPass tollbooths. PTV-VISSIMsimulation results show that full ETC tollbooth is 8 times faster than full MTCtollbooth.(4) We simulate the performance of the cellular toll plaza under differenttraffic throughput. Simulation results show that the average transit timeremains at about 11 seconds under different throughputs from 0 to 2000 (Unit:veh / h ). We can infer that this model is not sensitive to traffic flowvariations and has strong robustness which is suitable for practicalFor office use only F1 F2 F3 F4Team Control Number 56731 Problem Chosen B For office use onlyT1 T2 T3 T4construction.(5)To further reduce the possibility of accident, we improve the cellulartollbooth concept model: make the transition zone more smooth and arrangedifferent kinds of tollbooths more equitable.(6)For self-driving vehicles, in the center of the toll plaza, we reservespecial E-ZPass tollbooths, which match the characteristics of autonomousvehicles: safer and faster.Electronic toll collection and autonomous vehicles are the trends of modern transportation, our new designed model can improve the performance of toll plazain the aspects of cost, throughput and accident prevention.一种基于仿生蜂窝的新型收费广场概要在本文中，我们基于我们提出的数学模型分析了常用收费广场的表现。

基于物联网的停车场诱导系统外文文献及翻译

Parking Guidance Control System Based on Internet of Things IntroductionRoad construction in the city is becoming better,the parking lots as the main transportin frastructure,the construction of the parking area can effectively alleviate the city traffic congestion,therefore,the state has increased the construction of parking,especially the construction of intelligent parking lots.Parking space detection system as an important part of intelligent parking yard construction,detection function of parking spaces is the basis of parking space detection system operation, and the parking information transmission is the key of improving the efficiency of parking detection system.Therefore,This paper puts forward the research on Parking space detection system based on Magneto-resistive sensor and ZigBee,in order to improve the utilization efficiency of parking spaces.It has important significance to the construction of intelligent parking lot.This paper on the parking spaces were identified and judged by parking space detection node with reluctance sensor as the main detection function.Building a very powerful ZigBee wireless sensor network,the parking information data is transferred from one node to another node,and by way of relay is transmitted to the coordinator. And by designing the host computer display platform,Parking lot management can real-time observe occupancy of parking spaces,the implementation of effective management and monitoring of moving vehicle.The main research contents in this paper are as follows:(1)Combined with the characteristic and working principle of the magneto-resistive sensor,based on detailed analysis between network architecture of ZigBee technology,the network device type and network topology structure,the whole structure design of parking detection system is proposed.(2)On the basis of analyzing hardware structure of parking space detection nodes,the coordinator and router,the main hardware circuit module is designed in detail,includes a sensor module,a microprocessor module,serial communication module,power management module,antenna and balun matching circuit,and to complete the PCB design of the hardware circuit node.(3)The design of I2C bus driver,extraction of magnetic signal sensor detection, the use of parking space detection algorithm to determine the current state of parking spaces;based on the analysis of ZigBee protocol stack,the software design of node;application of Visual Studio2010to design a upper computer software,to realize the parking information visualization.To help drivers to quickly find a spare parking,a parking guidance control system was proposed.The principle of ultrasonic ranging was used to detect the state of a parking space,and through the internet of things the parking detector transmits the real-time information to the controlcenter.The control center mainly is an industrial computer and is responsible for dealing with the real-time information and sending the control command by internet of things.The guidance signs at each crossroad receive the wireless commands and execute them,by which the guidance function is performed.The internet of things was realized by ZigBee star network,in which the control center is a coordinator and other parts are routers or terminal equipments.The simulation experiment results show that the parking guidance system works well,and has the value of application and promotion to some extent.With the social progress and the economic development in china,people’s living way is changing greatly and cars have become the necessary tools for more and more people,which results in cars increasing rapidly,especially in cities.This phenomenon usually causes parking overcrowded and even chaos that is great inconvenience to people's lives.So we need try to deal with the problem by high-tech means.With the development and application of the internet of things technology,it is gradually entering the field of smart parking system that functions more powerful and intelligent,and is providing a more comprehensive technology service for the car owners.So the intelligent parking meets the need of keeping abreast of the times and is the fruit of high-tech development.The intelligent parking system can not only reduce the phenomenon of parking difficultly and save the car owner’s parking time, but also can promote the standardization construction of transport facilities. Furthermore,it can be easily combined into a more powerful integrated system with other intelligent systems,which is suitable for a variety of comprehensive advantaged management.To establish a set of intelligent parking toll collection management and guidance system that makes parking service is safe,simple and accurate,and to control the constructing cost and operating cost to the appropriate extent is the current trend of a parking management.Improving the work efficiency and overcoming the shortcoming of the traditional manual management is the ideal model of the modern parking.System ComponentsThe system performs the function of parking guidance according to the real-time state information in the parking and the counter values of parking regions,which reduces the parking time and improves the parking efficiency.As Fig.1shown,the system consists of control center,ultrasonic parking detectors,parking guidance signs, display of parking information and counters for different parking areas.The ultrasonicparking detectors is the basic of the guidance system,which collect the real-time state information for the control center;the parking region counter is used to count the number within some parking region and the core device is infrared transmitter and receiver;the parking guidance sign is usually realized by led lights,which is responsible for guiding th direction;the display screen is used to display the real-time parking information and notice;the control center may be realized by a industrial computer and is responsible for the overall management.Internet of ThingsIn order to achieve the communication between the various parts of theguidance system in a wide range of space,the internet of things is taken which is realized by ZigBee technology that is a low-power personal area network based on IEEE802.15.4 standard protocol.According to the protocol,ZigBee is a short-range,low-power wireless communication technology,which is characterized by a short distance,low complexity,selforganizing,low-power,low-data-rate,and low-cost.So it is suitable for the field of automatic control and remote control that can be embedded in a variety of devices.The ZigBee is realized by ZigBee module designed with TI's ZigBee chip —CC2530[6]as core.The CC2530System-on-Chip solution for2.4GHz is suitable for a wide range of applications and provides an IEEE802.15.4compliant radio transceiver.Furthermore,it provides an interface between the MCU and the radiowhich makes it possible to issue commands,read status,which makes it having excellent receiver sensitivity and robust 2530with enhanced 8051MCU kernel has rich peripheral,such as UART,12-bit ADC and21universal GPIO.And it can also be equipped with TI's standard and compatible or proprietary network protocol stack.The central server is as a network coordinator,the other parts as the terminal nodes.In the ZigBee network,star network is used,where industrial as the coordinator and other parts as router or terminal equipments.Parking Space DetectorTo complete the parking guidance the parking space detection is the basis of the parking guidance system,and the real-time state of the parking must be collected.As shown in Fig.3,the parking state detector comprises ultrasound ranging module,ZigBee data processors,the transmitting and receiving antenna and power. The device of transmitting and receiving is designed in the ultrasound ranging module. During the distance measuring,the transmitting part is triggered by the output signal of CC2530,and the time counter is cleared.Then the external interrupt events of CC2530is triggered by the ultrasonic echo signal,in which ultrasound reciprocal distance is calculated by calculating the ultrasonic round-trip time counter.When a car is parked,the distance gotten by ultrasound detector is significantly shorter than when there is no car parked.So according to this we can judge if there is a car in a parking place.ZigBee data processor converts the state information intomodulated signal by the internal transmitter and then the information is transmitted by the antenna.Through the wireless receiving device,the control center receives the real-time detection result of the parking state and programs the navigation.To complete the parking guidance successfully,only the parkingspace detection as parking sensor is not enough:when a car is driving to a parking place,the parking place will be unavailable for the other cars,though the parking place is not taken now. The working principle is as follows.The device is installed on the entrance and exit of a parking area.If a car is running into the entrance of the parking area,the receiver can’t receive the infrared because of blocking of the car and it triggers the counter to make the counter increased by one.On the contrary,if the car is leaving out of the exit of the parking area,the counter decreases by one.So we can know clearly how many cars exist in the parking area.By collecting the real-time information of the counters in different parking areas,and by combining with the state information of each parking space,the right guidance can be performed by the control center. Simulation ExperimentIn order to verify the scheme,a parking experimental model system was developed in the laboratory,where cars were replaced by electric remote control cars, and a personal computer was used as the control center.In addition,twenty four parking places were designed,and we got the areas In theexperiment,the situation that single car is on the road and the situation that multiple cars are on the road are separately tested.However,the phenomenon of competition for parking space and the phenomenon of error guidance didn’t appear and the simulation experiment result was good.ConclusionIn view of the problems of low automation level of manual service in parking lot, difficulty in finding an empty parking space and low parking efficiency of drivers,we proposed a parking guidance system.The guidance system is based on the internet of things that is realized by ZigBee communication.In addition,in the guidance system the central server was used as the central node.Manufacturing and Engineering Developments of a star network,and parking space detectors,parking guidance signs in crossings and parking area counters were used as terminal nodes.The simulation experiment shows that the guidance system can work well and steadily,and so has the value of application and promotion.基于物联网的停车引导控制系统引言城市的道路建设日趋完善，停车场作为主要的交通基础设施，停车场的建设可有效的缓解城市交通拥堵压力，因此，国家加大了对停车场的建设，尤其是智能化停车场的建设。
