The number of files stored on our personal computer (PC) is increasing very quickly and locating information in this environment is difficult. In this paper we present a set building blocks for implementing a system which is composed of four modules i.e. indexing mechanism, analyzing text, index storing and searching mechanism. The implementation of these four modules are described in details a...

Xavier de Montgros, Supply Chain Development Director at Hewlett-Packard (HP), was referring to HP’s Inventory-Driven Cost (IDC) metric, introduced in the late 1990s in an attempt to restore the company’s profitability in the highly competitive personal computer (PC) industry. The new performance measure was intended to focus the organization’s attention on creating value in the supply chain th...

The study, by the U.S. Federal Aviation Administration (FAA) Civil Aeromedical Institute (CAMI) in Oklahoma City, Oklahoma, found that one such personal computer (PC)–based simulator “can be a useful and economical tool for examining experimental questions involving general aviation pilotage,” despite some minor drawbacks. Although this study examined the uses of PCs and standard software for g...

Taking countries of the Organization for Economic Co-operation and Development (OECD), this paper analyzes factors affecting their software piracy rate (SPR) by taking into account several economic and technological variables. The empirical results show that per capita GDP (PerGDP), inflation, consumer prices (ICP), unemployment rate (UR), and high-technology exports (HTE) have positive correla...

The BBC microcomputer was one of several nationally produced which were superseded by the International Business Machines (IBM) Personal Computer (PC). This reflected the results of both an international market competition and rivalry between different US processor manufacturers. Along with the hardware, valuable software and supporting educational ideologies were discarded. As we make choices ...

In this paper we present a hardware realization of Kohonen's selforganizing feature map as a neural coprocessor connected to a personal computer (PC). We compare two concepts for this coprocessor, a vector-component-serial and processing-element-parallel array processor and a vector-component-parallel and processing-element-serial vector processor. Finally we give an overview about the whole sy...

Bit Error Rate (BER) is a principle measure of data transmission link performance. BER tester (BERT) consists of a Pattern Generator and an Analyzer that can be set to the same pattern. The payload data transmitted from the spacecraft consists of one, two or three channels per carrier based on the modulation scheme. The traditional equipments can do BER analysis for only one channel at a time. ...

This paper presents a microprocessor adapter for ATM networks. transmission direction can be supported optionally by a traf®c shaper, which is responsible for adapting emitted traf®c to ATM network. The microprocessor adapter, which can be used in terminals or in interworking units and switches, implements basic functions of the lower layers of the ATM protocol reference model. It uses three ap...

Cluster computing is now an accepted form of supercomputing. A cluster is a collection of computer (node) interconnected by a high-speed network. Each cluster node is either a workstation, a personal computer (PC), or a symmetric multiprocessor (SMP). The performance of a cluster system depends mainly on the bandwidth and latency of the network. In this paper, we propose a two new designs for a...

In order to enable the interested patient to gain access to his/her own medical records from a PC at home or a physician’s office, the PREPaRe system (Personal Repository for Electronic Patient Records) was designed by the Department of Computer Graphics and Computer Assisted Medicine at the Technical University of Berlin. This paper describes the visualization and interaction aspects of the PR...
