| Authors | A. Kumar and A. L. Vyas |
| Category | Electronics, Electrotechnics |
| Abstract | A single resistance controlled oscillator using two current conveyors, two (or three) grounded capacitors and three (or two) grounded resisters are presented. This paper presents the condition of oscillation and the frequency of oscillation for eight oscillator possible circuits. The proposed circuits enjoy oscillation control through a single grounded passive element. The group of passive component oscillator provides the following advantages e.g. the oscillation frequency can be independently controlled by grounded resistors and all the passive components which are suitable for IC implementation are grounded. The proposed circuit has very good frequency stability. Experimental results are found to be in conformity with the theoretical analysis. |

| Title | A Study on Complexation Equilibria and Spectrophotometric Determination
of CrIII, MnII and FeIII with Thiourea Monophosphazene Derivative |
| Authors | A.E. Arifien, G.M. Taha, A.A.M. Gad and M.Sh. Zoromba |
| Category | Chemistry |
| Abstract | The absorption spectra and acid-base characteristics of 1-phenyl-2,2-
(dianilino-N-phenylthiourea) monophosphazene, H2MPZ, were studied in
water-ethanol media . The equilibrium constants, molar absorptivities,
stability constants of the complexes of CrIII, MnII and FeIII with the ligand
H2MPZ have been determined spectrophotomerically in 10% ethanol at
250C and I = 0.1M NaNO3. The complexation equilibria in solution were
characterized using the graphical logarithmic analysis of the absorbance-pH
graphs. The micro-determination of the concerned metal ions was evaluated
by spectrophotometry based on the proposed complex formation M(H2MPZ)
and M(HMPZ)2 respectively. The effect of a number of interferent cationic
and anionic ions was also discussed. |

| Title | A Study On The Determination Of The Dynamic displacement Magnification Factor Which Varies With The Parameter Of Frequency Caused By The Anelastic Behaviour Of Material |
| Authors | Shen Jin-tao |
| Category | Civil Engineering |
| Abstract | This paper gives a method to determine the dynamic displacement
magnification factor which is according to C.Zener's theory of anelasticity [1] and some microscopic mechanism of anelastic phenomenon( internal friction, elastic creep, stress relaxation and variation of dynamic modulus with frequency of measurements or temperature) which are contrary to the theory of elasticity but are shown by real solids. In the discussion of physical interpretation of anelasticity presented in this paper we are concerned primarily with the physical origin of the anelastic effects. All such effects are different manifestation of the lack of
uniqueness of the relation between stress and strain. |

| Authors | Jan Haluza, Ivan Dolezal |
| Category | IT and Computing |
| Abstract | WWW caches are set up inparticular to increase WWW throughput and to decrease webpage access time(the time between creation of a request and its satisfaction). An improvement of networktransfer rates, as well as fast connectivity of terminals (users’ computers),could, however, bring increasingly embarrassing questions to an administrator,such as "Is the WWW proxy cache still an asset? What is raison d’etre forits deployment in a situation when there is a sufficient bandwidth bothin
LAN/MAN and for internationalbackbone connectivity?" |

| Title | About Structural Organization of Membranes in UV-resistant and UV-sensitive "Salmonella derby" Cell….. |
| Authors | Astghik Z. Pepoyan |
| Category | Chemistry |
| Abstract | The goal of this work was the investigation of correlation between some peculiarities of membrane phospholipids' structure and the UV-sensitivity of plasmid - carryingand plasmid-free Salmonella derby bacterial cells. Phospholipids and their fatty acids were determined by the method described in the work of Pepoyan at all (1993) and dynamics of free radical processes studied as described by Pepoyan at all (1991).The effect of R-plasmid on the qualitative and quantitative composition of phospholipids and their fatty acids has been found.
It has been shown that the comparative UV-sensitivity of plasmid - carrying S.derby mutants is most likely conditioned by the structure of DNA, its GC-pair content and by level of DNA methylation.
The result permits a conclusion that it isn't exclusive the decisive role of phospholipid molecules and its interaction with DNA in formation of the UV-resistance of plasmid-free S.derby cells. |

| Title | AN ALGEBRAIC SCHEME FOR THE DESIGN OF PID CONTROLLERS AND COMPENSATORS FOR LINEAR TIME INVARIANT CONTINUOUS SYSTEMS |
| Authors | K. Porkumaran, S. N. Sivanandam |
| Category | Electronics, Electrotechnics |
| Abstract | The design of a control system is concerned with the arrangement or the plan of the system structure and selection of suitable components and parameters. In classical control systems, the process of output response stabilization is attained by the selection of either Proportional - Integral- Derivative (PID) controllers or Phase compensators (Lead, Lag and Lead-Lag networks). This paper proposes an algebraic procedure for the design of controllers or compensators for a given Linear Time Invariant Continuous Systems (LTICS). The steps involved in this scheme are illustrated with the examples. |

| Title | An approach to reduce complexity in non-linear multiuser detection for DS-CDMA systems |
| Authors | Rekha Agarwal, Prof.B.V.R.Reddy and Prof. K.K.Aggarwal |
| Category | IT and Computing |
| Abstract | We present a method to reduced complexity using switching with existing Parallel Interference Cancellation (PIC) detector based on channel characteristics. The main criterion of taking PIC detector is that it has less Bit Error Rate (BER) and less processing delay than other nonlinear multiuser detectors. This proposed detector reduces overall complexity while maintaining the same performance as PIC detector. The switching mechanism is exploited by performance complexity tradeoff between matched filter detector and PIC detector. |

| Title | An efficient dynamic multicast agent approach for mobile IPv6 multicast |
| Authors | Hong-Ke Zhang, Bing-Yi Zhang, Bo Shen |
| Category | IT and Computing |
| Abstract | For providing multicast serve in mobility IPv6 network, two approachs have been proposed by IETF, i.e.MIP-BT (mobile IP-bi-direction tunnel) and MIP-RS (mobile IP-remote subscription). But there are some disadvange about them. The approach of MIP-BT has the problem of triangle route and tunnels congregation. The approach of MIP-RS has the problem of much handover latency and handover cost. The other present approachs are also cannot solve above problems effectively. So a novel approach named DMA (dyniamic multicast agent) is proposed in this paper. This approach integrats the merit of MIP-BT and MIP-RS and conquer their disadvange. It can reduce the times of multicast tree restructuring and allow MNs optimize multicase routes simultaneously through selectiong a new multicast agent dynamically. In addition, in this approach MN is left out of the most management and the load in MN is low. MN in the same subnet may select different DMA and the load in each DMA is lightened.The details is described in this paper including the throughness flow chart, the operation of MSA (multicast subnet agent), dynamic multicast agent selection and etc.. The simulation in NS is completed as well. The results in simulation denote that DMA approach can effectively avoid frequent modification multicast tree and the multicast packages can be forwarded through sub-optimal path. The DMA approach can improve the network performance effectively and adapt to the mobile IPv6 multicast. |

| Title | An Efficient Switched Detection Technique for DS-CDMA systems |
| Authors | Rekha Agarwal, Dr.B.V.R.Reddy and Prof. K.K.Aggarwal |
| Category | IT and Computing |
| Abstract | A dual-mode multiuser detector that dynamically switches its detection mode between matched filter and Minimum Mean Square Error (MMSE) detector operations based on channel characteristics is proposed. The main criterion of taking MMSE detector is that it has minimum Bit Error Rate (BER) among all linear multiuser detectors. This detector reduces overall computational complexity while maintaining the performance at tht same level as that of MMSE detector. The switching mechanism is exploited by the performance-complexity tradeoff, between matched filter and MMSE detector. |

| Title | An Optimized Version of Coordination Algorithm for Topology Maintenance in Ad Hoc Wireless Networks |
| Authors | V. Mahesh and S.K. Srivatsa |
| Category | IT and Computing |
| Abstract | This paper presents a power saving technique for multi-hop ad hoc wireless networks that reduces energy consumption without significantly diminishing the capacity or connectivity of the network. It builds on the observation that when a region of a shared-channel wireless network has a sufficient density of nodes, only a small number of them need be on at any time to forward traffic for active connections.
The technique used is a distributed, randomized algorithm where nodes make local decisions on whether to sleep, or to join a forwarding backbone as a coordinator. Each node bases its decision on an estimate of how many of its neighbors will benefit from it being awake and the amount of energy available to it. We give a randomized method using Voronoi diagram for rotating the coordinators with time, demonstrating how localized node decisions lead to a connected. |

| Title | Analysis of Mobile Communication spread and its implications in India |
| Authors | V.Thulasi Bai, A.Ganesan and S.K.Srivatsa |
| Category | IT and Computing |
| Abstract | The telecommunication network in India is one of the largest in the world providing wide-ranging services such as basic, cellular, internet, radio paging, VSAT etc. India is the fifth country to cross the 100 million mobile subscriber mark to join Russia, Japan, United States and China. Indian Telecom Sector is one of the fastest growing sectors of the economy, growing at an average of more than 20 percent over the last four years The country has an investment potential estimated at US$ 37 billion by 2005 and US$ 69 billion by 2010.
India has 48 million fixed telephone connections, growing at 22 per cent per annum and almost 100 million cellular phone connections, growing at 100 per cent per annum. The telecom network in the country comprises over 35,000 exchanges with switching capacity of over 47 million, 427 digital trunk automatic exchanges, and over 326,271 route km of optic fibre network. In addition to the two state-owned companies BSNL and MTNL, several private players have established a significant presence in both the basic and cellular markets.
The Indian telecommunications sector has undergone a major process of transformation because of significant Government policy reforms during the recent years. The New Telecom Policy, 1999 focused on creating an ideal environment for investment, establishing communication infrastructure by leveraging on technological development and providing affordable telecom services to all. These objectives of the policies have resulted in rapid growth of subscribers and lower tariffs. We believe that with these major initiatives of the Government, the mobile market in India will have a promising future. |

| Title | ANALYSIS OF SENTENCES FOR SYNTACTIC VALIDITY |
| Authors | N. Rajkumar, S.N. Sivanandam and M.R.Karthik |
| Category | IT and Computing |
| Abstract | The aim of this work is the design and implementation of a system which analysis the natural language input sentence to see if it is grammatically correct. To do so it uses different modules to identify the words of the structure in which these words appear is correct. The dictionary is maintained in a static database contained in a separate file. Another module is used for conversion of the input string (sentence) in to a list for further processing. The main program parses the list of words to check for grammatical validity, using the other two modules. Once the syntax analysis is performed, and the sentence is found to be grammatically correct, semantic analysis may be performed to understand the meaning of the sentence. However semantic analysis will not be undertaken if the sentence was syntactically wrong. |

| Title | Annihilation of a muon neutrino and an electron antineutrino into a muon and a positron in an external field |
| Authors | V. A. Gusseinov |
| Category | Physics, Astronomy |
| Abstract | One of the basic directions of modern physics of elementary particles is the study of interactions of high-energy particles in intense external fields. The successes of cosmology and astrophysics confirm existence of strong gravitational fields near to black holes and strong magnetic fields in neutron stars - pulsars. The value of magnetic fields in the magnetosphere of pulsars reaches the value H³ H0 , where H0= me2c3/ eh = 4.41´ 1013 Gs is the characteristic quantumelectrodynamic intensity of a field. |

| Title | Annihilation of a muon neutrino and antineutrino into an electron-positron pair in an electromagnetic field |
| Authors | V.A. Gusseinov |
| Category | Physics, Astronomy |
| Abstract | The cross section for the production of ultrarelativistic electron-positron pair in muon neutrino and antineutrino annihilation in an external electromagnetic field is calculated. The asymptotic behavior of the cross section as a function of the kinematical and field parameters is studied. It is shown that the new channel of the reaction arises at the expense of quantum effects. For the strong magnetic field case the cross section of the process does not depend on the masses of the charged leptons. The contribution of the weak external field to the cross section of the process is very small. It is shown that the considered process can be one of the possible sources of cosmic electrons and positrons of high energy. |
