The bibliography has been compiled as an introduction and study guide to this field. The papers listed describe the extensive theoretical and experimental results that have been obtained on quantum interference effects and discuss possible application areas. Works of a fundamental nature concerning phenomena that are basic to all semiconductor behavior have not been included. Articles on the properties and band structure of semiconductors, which are essential to a complete understanding of quantum interference effects, have not been included. Conference papers, though frequently very important, have not been included to conserve space. The papers are listed alphabetically according to the first author's surname. As in the compilation of any bibliography, numerous valuable and pertinent articles have probably been inadvertently omitted  相似文献

This paper reviews the history and present state of finite-element methods, as applied to electromagnetic-field problems in the microwave range (including element definitions and error estimation, guided wave propagation, scattering and antenna problems). It provides a selective bibliography, current as of the first months of 1996, with annotations and evaluative comments on the works surveyed. It briefly notes the capabilities of the finite-element method, and estimates how fully they have been realized to date. Some conjectures on the future of finite-element methods are also hazarded  相似文献

A desktop personal computer can be greatly extended in usefulness by attaching it to a local area network and implementing a full set of network protocols, just as one might provide for a mainframe computer. Such protocols are a set of tools that allow the desktop computer not just to access data elsewhere, but to participate in the computing milieu much more intensely. There are two challenges to this proposal. First, a personal computer may often be disconnected from the network, so it cannot track the network state and it must be able to discover and resynchronize with that state very quickly. Second, full protocol implementations have often been large and slow, two attributes that could be fatal in a small computer. This paper reports a network implementation for the IBM Personal Computer that uses several performance-oriented design techniques with wide applicability: an upcall/downcall organization that simplifies structure; implementation layers that do not always coincide with protocol specification layers; copy minimization; and tailoring of protocol implementations with knowledge of the application that will use them. The size and scale of the resulting package of programs, now in use in our laboratory for two years, is quite reasonable for a desktop computer and the techniques developed are applicable to a wider range of network protocol designs.  相似文献

Many people who are interested in learning about usability testing have trouble finding an entry point into the literature in the field. This briefly annotated bibliography addresses their needs by identifying recent, reasonably accessible articles and books organized in the following categories: general introduction to usability testing; usability testing of documentation (the process and general methods and tools); print documentation (discussions and examples of tests); and online documentation (discussions and examples of tests); the human-machine interface (the process, general methods and tools, and discussions and examples of tests); and textbooks on research design  相似文献

桌面应用Web化——应用接入架构   总被引:1,自引:0,他引:1  
C/S架构和B/S架构是大家都比较熟知的两种架构,目前,利用这两项技术所开发出的产品也很多,但是在定位产品所采用的架构问题上,这两种架构的优缺点却让人们难以取舍。因此,针对这一现象提出一种全新的应用接入架构。此架构能够很好地把C/S架构和B/S架构各自的优点有机的结合起来,形成一个多层体系结构,即不需要修改应用程序代码,就可以通过Web直接访问传统的桌面应用(即C/S应用),是一种新型应用部署和访问技术。同时,此架构还解决了在低带宽条件下的各种应用软件的远程访问速度问题。  相似文献

We have been developing a desktop virtual studio (DVS) that allows video producers to create various studio shots on a desktop work space as if those are shot in a real studio. Electronically generated or stored sets, actors, and a camera are integrated in a virtual workspace, and producers can manipulate them through specially designed man-machine interfaces. Our prototype DVS system can realize virtual shooting where two prerecorded actors are performing in virtual sets generated by real-time computer graphics. We discuss the prototype DVS and its application to desktop program production (DTPP)  相似文献

The bibliography includes articles dealing with the simultaneous independent shared use of computers. Real time, on-line, memory or facility allocation, multi-programming, and multi-processing terminology is evolved. Though a number of computer applications are reported, the requirements of special or dedicated time-sharing systems seem to be within the capability of most of the general-purpose time-sharing systems which are beginning to emerge. The systems are being designed for 100 percent availability, memory and facility allocation among users, a common file or data base, and direct access by the users via consoles (for example, typewriter, display, etc.).  相似文献

Thanks to the availability of various mobile applications, lots of users shift from desktop environments, e.g., PCs and laptops, to mobile devices, e.g., smartphones and tablets. However, there are still some desktop applications without counterparts on mobile devices, such as some integrated development environments (e.g., eclipse) and automatic industry control systems. In this paper, we propose Modeap, a platform-independent mobile cloud service that can push all desktop applications developed for various operating systems from cloud servers to mobile devices. Modeap follows a design principle of complete detachment and regeneration of desktop user interface, i.e., the essential graphical primitives of the original desktop applications will be intercepted and then translated into standard web-based graphical primitives such that the interactions between users and remote cloud applications become possible via mobile web browsers. In this way, all desktop applications built upon the same set of graphical primitives can be used on mobile devices in great flexibility without installing any new software. We have developed a proof-of-concept prototype that provides Windows applications from cloud server to mobile web browsers. The results of extensive experiments show that the proposed framework can achieve our design goals with low latency and bandwidth consumption.  相似文献

The growth of the World Wide Web has invested personal computer users with direct access to a wealth of information sources and services — for example, one can now check stock market share prices, book flight tickets or even do grocery shopping over the Internet. However, while the Internet enables direct access to various information sources and services, effectively integrating these services to provide a total solution to a complex task, such as arranging a transatlantic trip itinerary, remains a challenging task that requires significant human intervention. This paper discusses some of the challenges involved in providing computer-based integrated personalised travel services through a medium such as the Internet. Further, a software agent solution to this problem is presented, and an agent-based travel assistant demonstrator described, which was developed using the ZEUS collaborative agent building tool-kit.  相似文献
