一、玄关的设计

进门第一眼就看到,很明显就表达了它的重要性.那么什么是玄关呢?玄关一词源于日本,专指住宅室内与室外之间的一个过渡空间,也是进入室内换鞋、更衣、或者外出时候整理容貌和衣着的缓中空间.在住宅中虽然玄关的面积不大,但使用频率最高,更是进出住宅的必经之处.玄关也是一户人家的脸面,所以玄关既有实际的使用功能,又有较高的美观要求.玄关的设计形式主要有低柜隔断式、玻璃通透式、格栅围屏式、半敞半蔽式、装饰玻璃式及柜架等几种形式.     

点睛之笔——居室玄关设计

在居室装修中,人们往往最重视客厅的装修和布置,但对于玄关的装修总是被忽略。成功的中式新古典主义玄关设计价值取向是将传统文明与现代意识的相互融合,而不是在外型模仿和古代精神的生搬。中式新古典主义装饰风格非常考究。"移步就变景"的装饰手法,给空间带来了丰富的视觉效果展现了中国传统艺术的永恒美感。

通用输入型隔离器、隔离栅的设计

隔离器、隔离栅在工业控制系统中承担着信号的隔离和传输的作用,而现场传感器的信号类型多种多样,如电流信号、电压信号、热电阻信号、热电偶信号、毫伏信号、电阻信号等。目前,传统的隔离器、隔离栅是针对每一种或几种信号来设计不同的产品,因此产品的种类比较多,无形中给客户选型增加了难度。为了便于客户选型,增加产品通用性,设计了一款通用输入信号的隔离器、隔离栅;同时,为提高产品生产效率、降低硬件成本,采用通用型产品嵌入式软件的设计理念,减少生产标定工序。这意味着该设计可以大大降低产品种类,提高库存利用率。试验数据表明,产品全信号类型精度优于0.05%。

Security is a Process,Not a Product: Managing User IDs in the E-business Era

Picture the scene: you’re just leaving your house for work in the morning and before setting off you run a quick security check. All windows are closed, the back door is shut and the alarm set before you double lock the front door. You then place the front door key under the welcome mat with a sign saying ‘look under here’. This is what thousands of organizations are doing by failing to monitor and manage their user IDs effectively, because they are the technology equivalent of a master key to your network systems.     

超宽带Rake接收机结构的研究

超宽带信号在室内密集多径环境下会产生严重的时间弥散,信号的传输性能将会下降,Rake 接收是提高超宽带接收机性能的重要手段。然而如何确定接收机的叉指数目成为接收机设计过程中的关键问题。基于 IEEE802.15.3a 室内超宽带多径信道模型,采用二进制相移键控(BPSK)调制方式时,选用最大比合并(MRC)方式对 Rake 接收机的超宽带通信系统的性能进行了仿真。仿真得出了最佳的合并叉指数目,结果表明在最佳的合并叉指数目情况下的系统性能较其他叉指数目情况下的系统性能更为优越,验讧了选取此叉指数目的有效性。此方法大大有利于 Rake 接收机的设计。

Vision Based Output Feedback Control of Micro Aerial Vehicles in Indoor Environments

We present a new image based visual servoing (IBVS) approach for control of micro aerial vehicles (MAVs) in indoor environments. Specifically, we show how a MAV can be stabilized and guided using only corridor lines viewed on a front facing camera and angular velocity measurements. Since the suggested controller does not include explicit attitude feedback it does not require the use of accelerometers which are susceptible to vibrations, nor complex attitude estimation algorithms. The controller also does not require direct velocity measurements which are difficult to obtain in indoor environments. The paper presents the new method, stability analysis, simulations and experiments.

Reliability-based multiobjective optimization for automotive crashworthiness and occupant safety

This paper presents a methodology for reliability-based multiobjective optimization of large-scale engineering systems. This methodology is applied to the vehicle crashworthiness design optimization for side impact, considering both structural crashworthiness and occupant safety, with structural weight and front door velocity under side impact as objectives. Uncertainty quantification is performed using two first order reliability method-based techniques: approximate moment approach and reliability index approach. Genetic algorithm-based multiobjective optimization software GDOT, developed in-house, is used to come up with an optimal pareto front in all cases. The technique employed in this study treats multiple objective functions separately without combining them in any form. It shows that the vehicle weight can be reduced significantly from the baseline design and at the same time reduce the door velocity. The obtained pareto front brings out useful inferences about optimal design regions. A decision-making criterion is subsequently invoked to select the “best” subset of solutions from the obtained nondominated pareto optimal solutions. The reliability, thus computed, is also checked with Monte Carlo simulations. The optimal solution indicated by knee point on the optimal pareto front is verified with LS-DYNA simulation results.     

Vision-based entrance detection in outdoor scenes

Doors are a significant object for the visually impaired and robots to enter and exit buildings. Although the accuracy of door detection is reported high in indoor scenes, it has become a difficult problem in outdoor scenes in computer vision. The reason may lie in the fact that such properties of a simple ordinary door such as handles, corners, and the gap between the door and the ground may not be visible due to the great variety of doors in outdoor environments. In this paper, we present a vision-based method for detecting building entrances in outdoor images. After extracting the lines and deleting the extra ones, regions between the vertical lines are specified and the features including height, width, location, color, texture and the number of lines inside the regions are obtained. Finally, some additional knowledge such as door existence at the bottom of the image, a reasonable height and width of a door, the difference between color and texture of the doors and those of the neighboring regions, and numerous lines on doors is used to decide on door detection. The method was tested on the eTRIMS dataset, door images from the ImageNet dataset, and our own dataset including doors of houses, apartments, and stores leading to acceptable results. The obtained results show that our approach outperforms comparable state-of-the-art approaches.
