TL;DR: A virtual drive array controller enables plural physical devices, which may be of a single type of device or a combination of multiple types of devices, to be represented to the computer system as a single logical drive as mentioned in this paper.
Abstract: A computer system having a virtual drive array controller incorporated therein The virtual drive array controller enables plural physical devices, which may be of a single type of device or a combination of multiple types of devices, to be represented to the computer system as a single logical drive The virtual drive array controller includes a front end coupled to a secondary storage bus and a back end to which plural physical devices are coupled Additional virtual drive array controllers may be arranged in a cascading configuration by coupling the additional virtual drive array controllers to the back end of the virtual drive array controller

TL;DR: In Part I a technique based on optical orthogonal codes was presented to establish a fiber-optic code-division multiple-access (FO-CDMA) communications system and it was shown that using an optical hard-limiter would, in general, improve system performance.
Abstract: For pt.I see ibid., vol.37, no.8, p.824-33 (1989). In Part I a technique based on optical orthogonal codes was presented to establish a fiber-optic code-division multiple-access (FO-CDMA) communications system. The results are used to derive the bit error rate of the proposed FO-CDMA system as a function of data rate, code length, code weight, number of users, and receiver threshold. The performance characteristics for a variety of system parameters are discussed. A means of reducing the effective multiple-access interference signal by placing an optical hard-limiter at the front end of the desired optical correlator is presented. Performance calculations are shown for the FO-CDMA with an ideal optical hard-limiter, and it is shown that using an optical hard-limiter would, in general, improve system performance. >

21 Mar 2001TL;DR: A web agent is a component (usually software, but can be hardware or a combination of hardware and software) that plugs into (or otherwise integrates with) a web server (or equivalent) in order to participate in providing access services.
Abstract: An access system provides identity management and/or access management services for a network. An application program interface for the access system enables an application without a web agent front end to read and use contents of an existing encrypted cookie to bypass authentication and proceed to authorization. A web agent is a component (usually software, but can be hardware or a combination of hardware and software) that plugs into (or otherwise integrates with) a web server (or equivalent) in order to participate in providing access services.

TL;DR: Front-End Vision and Multi-Scale Image Analysis is a tutorial in multi-scale methods for computer vision and image processing that builds on the cross fertilization between human visual perception and multi- scale computer vision theory and applications.
Abstract: Front-End Vision and Multi-Scale Image Analysis is a tutorial in multi-scale methods for computer vision and image processing. It builds on the cross fertilization between human visual perception and multi-scale computer vision (`scale-space') theory and applications. The multi-scale strategies recognized in the first stages of the human visual system are carefully examined, and taken as inspiration for the many geometric methods discussed. All chapters are written in Mathematica, a spectacular high-level language for symbolic and numerical manipulations. The book presents a new and effective approach to quickly mastering the mathematics of computer vision and image analysis. The typically short code is given for every topic discussed, and invites the reader to spend many fascinating hours `playing' with computer vision. Front-End Vision and Multi-Scale Image Analysis is intended for undergraduate and graduate students, and all with an interest in computer vision, medical imaging, and human visual perception.

TL;DR: An overview is given of the Field environment, which was developed to show that highly integrated, interactive environments like those on PCs can be implemented on workstations and can be used for classical-language and large-scale programming.
Abstract: An overview is given of the Field environment, which was developed to show that highly integrated, interactive environments like those on PCs can be implemented on workstations and can be used for classical-language and large-scale programming. Field connects tools with selective broadcasting, which follows the Unix philosophy of letting independent tools cooperate through simple conventions, demonstrating that this simple approach is feasible and desirable. Field achieves its goals by providing a consistent graphical front end and a simple integration framework that lets existing and new Unix tools cooperate. The front end is based on a tool set called the Brown workstation environment. The framework combines selective broadcasting with an annotation editor that provides consistent access to the source code in multiple contexts and with a set of specialized interactive analysis tools. Field's integration framework and message facility are described. >
