5411.60GHz移动收发器的判决反馈均衡器设计
[计算机、通信和其他电子设备制造业] [2013-11-18]
The 7GHz of bandwidth available in the 60GHz band offers an opportunity to achieve multi-Gb/s wireless links. For this reason, ultra-high data-rate wireless communication over the 60GHz band has gained increasing interest from both academic and industrial groups.This report first presents the design methodology for a mixed-signal DFE. The technique can be used to explore the design space and compute the power dissipation of a DFE as a function of data-rate and the number of taps (i.e. the channel characteristics).

5412.无线电应用识别中的低功率频谱感知
[计算机、通信和其他电子设备制造业,电气机械和器材制造业] [2013-11-17]
In this report, we reviewed the requirements and challenges of performing spectrum sensing in the TV band for mobile applications. We described the existing state of this area of research from both a technical and a policy perspective, and reviewed existing theoretical techniques for performing signal detection. We then proposed a novel physical implementation of a spectrum sensing system by using subsampling autocorrelation in the analog domain.

[计算机、通信和其他电子设备制造业,信息传输、软件和信息技术服务业] [2013-11-17]
This paper describes the need for adaptive gait tuning on an eight-legged robot, which will enable it to adjust its gait parameters to increase the speed at which it navigates difficult and varying terrains. Specifically, we characterize the robot’s performance on varied terrains and use the results to inform the implementation of a finite-difference policy gradient reinforcement learning algorithm.

5414.CrowdBrush:人群图片编辑移动应用程序
[信息传输、软件和信息技术服务业] [2013-11-17]
We have developed an android application for photo editing on top of a low cost crowdsourcing system. We use the crowdsourcing platform to add interesting effects to images taken by users which they can later share with their friends. CrowdBrush application thus provides a feature of custom photo editing, which is missing from the current photo manipulation applications in the market. Additionally, the system produces “human-verified” results as it relies on human (crowd) involvement in the process and guarantees an end product which is aesthetically pleasing.

5415.对理解和有效权限系统
[信息传输、软件和信息技术服务业] [2013-11-17]
How can we, as platform designers, protect computer users from the threats associated with malicious, privacy-invasive, and vulnerable applications? Modern platforms have turned away from the traditional user-based permission model and begun adopting application permission systems in an attempt to shield users from these threats. This dissertation evaluates modern permission systems with the goal of improving the security of future platforms.

5417.递归单程序、多数据程序的团队分析建议
[信息传输、软件和信息技术服务业] [2013-11-17]
Large-scale parallel machines are programmed primarily with the single program, multiple data (SPMD) model of parallelism. This model has advantages of scalability and simplicity, combining independent threads of execution with global collective communication and synchronization operations.We discuss the information required by those analyses and provide a rough sketch of a team analysis for computing that information. We hope that this sketch can be used as a basis for future implementation of a complete team analysis.

5418.固态照明市场的LED技术分析
[电气机械和器材制造业] [2013-11-17]
Light emitting diode (LED) technologies present significant advantages compared to today’s lighting solutions: LEDs are favorable in terms of their electrical efficiency, economical value, and environmental impact. The question remains, when, if at all, will these technologies replace all the light bulbs and tubes in the world? We addressed this question by surveying both the technology and market landscape for solid state lighting. We found that solid state lighting technologies will become the dominant lighting solution within several years, as they steadily improve in color quality, brightness, and cost, and receive support from environmental and political policies.

Traditional Chinese Medicine treats pulse diagnosis as a very important diagnostic tool which can give very detailed information on the state of the state of internal organs. However, it is seldom used by people in monitoring their own daily health because it requires training and experience. We’ve designed a personal ‘Pulse Reading’ sensor gadget that can take the pulse information from three different wrist positions at the same time and detect the frequency, stress, rhythm and the change under three different pressures. It can also communicate with a personal computer and show readings that can be used for stress recognition based on Traditional Chinese Medicine. A wide market survey of this kind of product was done to set the value of the product before starting to make the prototype. The MEMS sensor and sensor package survey were studied in order to build an accurate and stable sensor of right size and with appropriate output and a reasonable price. Pulse signals were denoised and screened through matlab and stress pattern recognition was built using a BP neural network. Finally, we built the prototype which consists of a pulse reading gadget, an analog/digital conversion part which lets the sensor gadget communicate with a computer and the matlab programming, which process the pulse signals and identifies the stress levels. The accuracy of the testing data for classifying stress is about 75%. The product cost is 100 times lower than similar existing commodity. Overall, we believe that this product will let people monitor their health and benefit from this information more conveniently and effectively than the can at present.
