Fourier analysis is a mathematical technique based on decomposing signals into sinusoids. The discrete Fourier transform (DFT) is the technique used with periodic digitized signals. There are several ways to calculate the discrete Fourier transform, such as solving simultaneous linear equations, the correlation method and fast Fourier transform (FFT). While FFT produces the same result as the other approaches for calculating DFT, it is incredibly more efficient, often reducing the computation time by about three hundred times as compared to other DFT techniques. To demonstrate the practical aspects of fast Fourier transform, a speaker testing system is developed and different speakers are tested for buzzing. Buzzing is a common problem in speakers. To detect a speaker for buzzing, an interactive PC based system has been developed, and, using this system, a speaker can be easily analyzed. Also, by using this system, the testing time is greatly reduced and the test data can be saved in the form of a graph of frequency versus % total harmonic distortion (THD). Both the hardware and the software for this system are discussed.","PeriodicalId":284251,"journal":{"name":"IEEE Students Conference, ISCON '02.

These three entities are independent of each other and run as separate processes. All these entities are configurable through an Xwindows based configuration CUI. The implementation fully conforms to RFC 2002 'SHOULD' requirements and supports IPin-IP encapsulation, FA care-of-address, keyed-MDS \"prefix + suffix\" mode of authentication and IEEE 802.1 1 wireless interfaces.

GPS is undergoing tremendous growth, with many product innovations being made. Furthermore, technology advances are leading resulting organizational and institutional changes, which wil l have a profound impact on the ”positioning professions”, as well as on the community in general. Location commerce or “L-Commerce” has become the latest buzzword to circulate, among ’ telecommunications industry watchers tracking new trends in the wireless arena. L-Commerce wil l help connect businesses with their most qualified customers, quickly direct individuals to the services they desire, and even increase the efficiency of emergency services. The convergence of multiple technologies including geographic information systems (CIS), Internet, wireless communications, location determination, and portable devices has given rise to exciting new types of information utilities that may be referred to simply as location services. Also called mobile location services, wireless location services, or location-based services, these systems are making a major impact on how we navigate our world and how business i s done. Knowing where a person or object i s at any time presents a powerful new dimension to’ the kinds of information services that can be offered. Location services deliver geographic information between mobile and I or static users via the Internet and/or wireless network. L-Commerce has combined the technologies of mobile computing / wireless communication with Global Positioning System (GPS), to provide a wide range o f location-dependent services to the general public (such as roadside assistance, concierge services, location-sensitive advertising). The Governments are working on the grounds to provide location-based data to the public. US government has already announced that GPS will be freely available to general public by the current decade [ZOOO]. In this paper, L-Commerce i s presented with reference to future trends in mobile computing and GPS technology.

Mansoor","doi":"10.1109/ISCON.2002.1215937","DOIUrl":"https://doi.org/10.1109/ISCON.2002.1215937","url":null,"abstract":"Bluetooth (BT) is a new short-range (10 m) wireless personal area network (WPAN) technology, operating in the globally unlicensed 2.4 GHz ISM band. At present, BT's scope appears limited to direct, single hop communication and cable replacement. However, it seems destined to grow into applications that would require indirect communication (multi-hop) support such as large conferences and even BT telephony. The author feels that the primary hurdle BT needs to defeat is the lack of support for multi-hop routing of data/voice packets in BT networks. While most contemporary research on BT has focused on BT usage scenarios profiled at the launch of the technology, the author feels that the standard has the potential to grow into areas such as Bluetooth telephony, where BT enabled phone sets would be able to allow users to communicate over large distances, with no charge. Thus, the need for efficient packet routing is born. The algorithm presented intends to offer a low cost, backward compatible solution by building on top of existing BT functionality (while leaving it intact), and distributing the burden of determining and maintaining routes (through the BT scatternet) and routing vectors between the various BT entities in the BT scatternet.","PeriodicalId":284251,"journal":{"name":"IEEE Students Conference, ISCON '02.

Virtual private networking technology provides the medium to use the public Internet backbone as an appropriate channel for private data communication. By replacing expensive private network bandwidth with relatively low-cost bandwidth, much of the remote communications burden is transferred over to ISPs. A multilayer technology, multiprotocol label switching (MPLS), offers an alternative tunneling mechanism for implementing IP VPNs. MPLS combines the performance of layer 2 switching with layer 3 routing to provide a scalable and flexible architecture for building VPNs. MPLS represents the next level of standards-based evolution in combining layer 2 (data link layer) switching technologies with layer 3 (network layer) routing technologies. The primary objective of this standardization process is to create a flexible networking fabric that provides increased performance and scalability. This includes traffic-engineering capabilities, which provide, for example, aspects of quality of service (QoS), and facilitate the use of virtual private networks. This paper covers the general idea of MPLS in VPNs; it also covers a quantitative analysis of MPLS in VPNs.","PeriodicalId":284251,"journal":{"name":"IEEE Students Conference, ISCON '02.
