38851.公共交通系统运营决策的混合预测控制
[信息传输、软件和信息技术服务业,铁路、船舶、航空航天和其他运输设备制造业,计算机、通信和其他电子设备制造业] [2013-12-13]
The optimization of the real-time operations associated with a bus system is formulated under a hybrid predictive control (HPC) approach. Both the objective function and the predictive model are essential for HPC design. For the sake of simplicity, in this work, the HPC framework is constructed for a single-loop bus system, although it could be extended to more complex systems according to a similar modeling framework. The system is represented in Fig. 4.1. The network is a one-way loop route with P equidistant stops and b buses running around the loop under the control of the dispatcher.

38853.家电行业季度分析报告——2013年2季度
[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] [2013-12-12]
今年家电行业的走势与去年相反,上半年家电下乡和节能补贴相继收官,提前释放了一些市场需求;与去年同期相比,行业前期的基数也较低,这使得行业增长率十分可观。国内外众多品牌今年均携手旗下全线大、小家电“重装上阵”,与往年不同的是,这些家电都有了智能互联的趋势。中国家电协会分析指出,目前随着中国大众消费者的消费能力不断提高,仅能满足基本功能需求的家用电器已经不能满足消费者的要求。

38854.全球生物模拟市场报告(2014-2018年)
[计算机、通信和其他电子设备制造业,医药制造业] [2013-12-11]
Biosimulation is the simulation of biological processes and systems, and is aided by computers. It plays an important role in the drug discovery and development process. The drug discovery and development process can be broadly classified into the following stages: target identification, target validation, lead discovery, lead optimization, and pre-clinical and clinical testing. Biosimulation is employed during all these stages and supports decision-making. One of the key roles of biosimulation in the drug discovery and development process is that it enables trials on a virtual patient population, thereby reducing the need for clinical trials on humans and animals. Thus, biosimulation provides immense value to pharmaceutical companies in terms of reducing both R&D time and costs.

[计算机、通信和其他电子设备制造业] [2013-12-10]
The exponential improvements in speed, energy efficiency, and cost that the computerindustry has relied on for growth during the last 50 years are in danger of ending within thedecade. These improvements all have relied on scaling the size of the silicon-based transistor that is at the heart of every modern CPU down to smaller and smaller length scales. However, as the size of the transistor reaches scales that are measured in the number of atoms that make it up, it is clear that this scaling cannot continue forever.

38856.安全信息自动取款机(SIATM)的正式完整框架与应用
[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] [2013-12-10]
Information Security is traditionally treated in three main categories: Con dentiality, Integrity, and Availability. While much work has been done on modelling Con dentiality and Availability, aspects involving comprehensive modelling and quality of data integrity in complex systems appear to be, on a relative scale, much less well understood and implemented. Further, most work on Integrity and resultant implementations seems to have focussed more on a matters related to source authentication and transmission assurance. However, the quality of data aspect is becoming more critical for attention, given the increasing levels of automation of information fusion and data transformation in a globalised Cyberspace. In this paper, we survey the existing integrity models and identify shortcomings of these with regard to a general integrity framework encompassing the quality of data aspect. We then propose and formally model a new framework, illustrating the approach with reference to use cases built around the Secure Information ATM (SIATM) - a highly accreditable security system currently under development.

38859.光伏阴影模块级电力电子实验平台
[计算机、通信和其他电子设备制造业] [2013-12-08]
This document describes a repeatable test procedure that attempts to simulate shading situations, as would be experienced by typical residential rooftop photovoltaic (PV) systems. This type of shading test is particularly useful to evaluate the impact of different power conversion setups, including microinverters, DC power optimizers and string inverters, on overall system performance. The performance results are weighted based on annual estimates of shade to predict annual performance improvement. A trial run of the test procedure was conducted with a side by side comparison of a string inverter with a microinverter, both operating on identical 8kW solar arrays. Considering three different shade weighting conditions, the microinverter was found to increase production by 3.7under light shading, 7.8under moderate shading, and 12.3under heavy shading, relative to the reference string inverter case. Detail is provided in this document to allow duplication of the test method at different test installations and for different power electronics devices.

38860.大功率板坯耦合的光波导激光器和放大器
[计算机、通信和其他电子设备制造业] [2013-12-08]
The development of a high-brightness semiconductor diode laser/amplifier concept, which utilizes a slab-coupled optical waveguide (SCOW) region to achieve several important advances in performance, has been presented. SCOW devices are capable of single-spatial-mode operation with a single-lobed, large-area, low-aspect-ratio beam that is easily coupled to a single-mode fiber with high-coupling efficiency. The SCOW concept is applicable to a wide variety of semiconductor material systems and wavelengths of interest.
