In the modern age we will aware about the ATM and cash deposit machine. However the problem like fake note detection is not preferably solved. A simple algorithm to be implemented in the ATM to detect the fake notes in ATM across the country. The algorithm makes ATM more efficient and reliable system. We present a new error control approach for continuous media communication protocols. Since continuous media data are inherently bursty these protocols commonly uses a control time for the first packet in a burst to ensure continuous play back in the presence of delay jitter.
The retransmission scheme which is called slack automatic repeat request is based on appropriately extending the control time for the first packet in a burst to allow for the timely retransmission of last packets i.e. before the lost packet is due for playback. We present simulation results that demonstrate the feasibility and effectiveness of this retransmission scheme under a realistic scenario for an optical FDDI networks.
A haze weather monitoring method using satellite signal of EBPSK modulation is constructed in this paper. The core of the method is a three-dimensional (3D) water vapor reconstruction model. The distances between satellites and ground-based receivers are known. In the calculation process, troposphere delay could be solved by differential process. The troposphere delay is used for water vapor distribution calculation on the signal path. Raw water vapor data is received through the array of land-based receiver. The boundary values are presumed known, the 3D distribution in of water vapor is calculated by the 3D haze weather monitoring model. In order to improve the accuracy of the calculation, the differential method and average method are used as error reduction strategies. The validity of 3D water vapor reconstruction model is proved by the calculation example of land-based EBPSK satellite array receivers.

DNA cryptography is a new born information security field and has been the international frontier of cryptography emerged with the constantly invasion of traditional cryptography and improvement of research on DNA computing and bio-technology. Based on the problem of fragment stitching, this work was made for introducing the background of DNA cryptography, and briefly describing the features of DNA molecular, key biotechnologies and related software. Then we study the difficult biological problem which is the key and basic part in designing of DNA encryption. We put forward own difficult problem which is to assembly when overlaps are destroyed and prove its difficulty with examples. After analysis of encoding of DNA and mechanism of symmetric encryption, we design a symmetric system using the technology of DNA digital coding and DNA fragment assembly. And the security analysis proves that the scheme has high confidential strength.
The use of low melting sulphate glasses and metal chelates as fire and smoke retarder additives for PVC has been described . The results obtained with several metal containing addivtives, flame retardent plasticizers, low melting sulphate glasses and transition metal chelates are briefed below.The severity of exposure required to produce combustion and the results of the combustion process vary as widely as the materials themselves. Since overall fire hazards is a function not only of the fire performance of the material but also of the degree of exposure of the material and the probability of occurrence and the nature of the fire involved. All of these factors must be considered in determing the degree of inherent fire resistance which the material must possess to be satisfactory for a particular application.
In this study, we propose a comprehensive adjustable educational evaluation model, which involves the practical experiences and preferences of first-line educators. We define and devise some useful concepts and methods such as the Original natural preference degree. The detailed process is presented with an illustrative numerical example. The method proposed in this study obeys the Monotonicity principle which can show the effectiveness and efficiency in the evaluation model.
This paper has investigated interaction between domestic investment and foreign direct investment (FDI) for period 1976 to 2010 for Pakistan. Theoretical literature pointed positive relation between FDI and domestic investment and most of empirical studies also support positive correlation expect few cases. FDI improves domestic investment through technological diffusion, gain economies of scale and provide access to international market. The study is also trying to evaluate the interdependence of FDI and domestic investment. This study adopted unit root analysis, cointegration and causality techniques for the empirical investigation; the outcomes of this study suggest that FDI has positive impact on investment and similarly domestic investment has positive association with FDI which implies that FDI and domestic investment reinforce each other and thus we reject the crowding out Hypothesis in case of Pakistan. There is need of popper policy implementation and government should give incentives to augment FDI inflow, including subsidies and tax exemption to the foreign firms.
Dis-intermediation and competition have forced banks to look for new ways to boost their returns. One of the routes adopted by the banks is that of consolidation. Mergers and acquisitions have been used to expand revenues and cut costs. Consolidation of banks through Mergers and Acquisitions is not a new phenomenon for the Indian banking system. It has been going on from the early days of modern banking when three Presidency banks merged in to form of the Imperial Bank of India in 1921. The study has been undertaken to make a comparison of the performance of the Banaras State Bank (BSB) and Bank of Baroda (BOB) prior and after the merger on the basis of various financial ratios. All efforts are towards judging whether the merger of banks has been fruitful or not and benefit of synergies has been obtained or not. For the purpose of analysis ratio of four years prior to a merger and four years after merger have been compared. The analysis of financial ratios shows that efficiency has increased after the merger of BOB and BSB. Improvement has been observed after merger in total income to total capital ratio, interest income to interest expenditure ratio, net profit to total capital ratio, advances to deposits ratio and advances to total assets ratio. Poor performance has been observed in the case of deposits to total assets ratio, deposits to investment ratio, fixed asset to total assets, total income to total assets ratio and net profit to total assets ratio.
