Enhancing PC Security with a U-Key

A boot system that uses a U-Key can help ensure the integrity of fairly static PC components. Moreover, the associated two-factor authentication makes a mobile computer's theft less likely because a thief can't use it

Finite-element analysis on a PC

The authors describe how they achieved mainframe performance by coding the Cosmos/M finite-element analysis system, a commercial product, for a PC enhanced with a parallel-processing board. The discussion covers design goals, algorithm design, implementation and debugging, performance optimization, and scalability. They focus on financial, algorithmic, and numerical issues, with almost no reference to the numerical principles involved in solving stress-analysis equations     

Designing a PC game engine

Computer game engine requirements change in response to evolving game platforms and demands for reduced development costs. We propose a 3D game engine, marketed as NetImmerse, for varying performance levels     

Building a multimedia ISDN PC

A personal-computer-based architecture that uses graphics methods to improve cooperative multimedia work over integrated services digital networks (ISDNs) is discussed. The system supports cooperative multimedia work by providing real-time video, graphics, and speech. The system requirements, components, and general architecture are considered, as is the implementation of the system     

PC机与多台8051单片机间通信的实现

在微机机群上用PGHPF实现并行粒子模拟

由微机组成的微机机群因其高性能价格比正受到各研究领域的关注。我们建立了一个有16个PentiumPro2000MHzCPU的微机机群，并在此微机机群上用PGHPF实现了二维和三维并行粒子模拟程序。结果表明，PGHPF的性能要号MPI相比拟，最多用16个CPU同样能达到比较高的并行效率。     

User Satisfaction with Tablet PC Features

Previous studies of tablet personal computers have concentrated on their use in education and healthcare. The current study focused instead on personal usage, investigating how satisfied users are with their own tablets after having used them in their daily lives. The objective was to identify the major features for tablets and to investigate how form factors affect the preference of functions by performing a comparison of iPad1 and Galaxy Tab. Also, gender and ethnicity were analyzed to determine whether they influence satisfaction with the devices. For e‐mail and web browsing functions, users’ ratings showed more satisfaction with the iPad1 since it has a larger display; for the e‐book reader function, users indicated higher satisfaction with the Galaxy Tab. Male users evaluated their devices by the function itself, whereas female users were mainly concerned with aesthetic aspects. Koreans indicated that they were less satisfied with their tablets than were other ethnic groups.

Turning your PC into a CAD workstation

Computer-aided design (CAD) packages are now available on some personal computers, and can make a good entry system for design offices. However, it is important to take into account the additional costs that might be incurred e.g. more memory, a graphics monitor, a lightpen etc.     

东芝Thrive平板电脑配Android3.1

<正>谷歌近期发布里一款平板电脑升级系统Android3.1,很多厂商宣布了产品的升级方案。与Android3.0相比,Android3.1的界面进行了调整与美化,支持可改变大小的widget工具,增加了多个内置应用程序,同时对WIFI、USB、邮件等功能进行了优化。该系统升级后最大的一项改进就是,原来在Android3.0上无法兼容的大多数的An-droid 2.X版本的应用程序,在Android3.1可以得到更多的应用。
