Increasing Concentration of Some Elements in Groundwater Due to Lack Vadose Zone in
Abstract: The authors in their professional praxis have seen that the presence and absence of vadose zone in the upper part of aquifer, with intergranulary porosity type, is a prerequisite for enhanced concentrations of iron and manganese in groundwater. The natural aeration zone in vadose zone of the upper part of aquifer enables additional enrichment of groundwater with oxygen, which is spent on the account of biochemical processes in the direction of their flow. The absence of this zone in aquifer directly influences higher iron and manganese content in groundwater, often above the permissible concentration in drinking water. In order to eliminate this problem, in this paper proposals of future works were made, different of the usual procedure of hydro geological research. It will bi possible to examine the effect of aeration of groundwater in the aquifer, during the performing of the wells. Kew words: vadose zone, iron, manganese, hydrochemistry, groundwater 1.0
FPGA Implementation Of Efficient Modified VLSI Architecture For Multiplier
Abstract: The multiplication operation is present in many parts of a digital system or digital computer and also in signal processing, graphics and scientific computation. With advances in various technologies, various techniques have been proposed to design multipliers, with high speed, low power consumption and lesser area. Various high speed low power compact VLSI implementations are possible only with multipliers. This project presents a high- speed and low area 16×16 bit Modified Booth Multiplier (MBM) with Carry Select Adder (CSA) and 3-stage pipelining technique. These techniques to improve the performance by reducing the time delay. These multiplication techniques are design using hardware description language (HDL) and it can simulate using modelsim software and also it will implement in Spartan 3E FPGA and also power consumption will estimate using tanner EDA tool.

Abstract: In this paper, we investigate the following third-order three-point semipositone boundary value problems: ( ) ( , ) 0, (0,1); (0) ( ) (1) 0, u t f t u t u u u Under the conditions that the nonlinear term ( , ) f t u :(0,1) (0, ) ( , ) is continuous, i.e., we allow that the nonlinear term f is both semipositone and lower unbounded. By using the fixed-point index theory, the existence of positive solution and many positive solutions are obtained.

A Framework Extension To Support Flash Crowd Using Service Differentiation At The Application
Abstract: Software As Service (SAAS) from CLOUD represents an Application Layer of networks. The Security need of Application layer is to protect the DATA or FILE in that layer. Various types of Distributed Denial Of Service Attacks(DDOS) have been performed on this layer in order to steal the DATA or consume the resource from the Application. The current challenge in network security is to propose a framework that separate the ddos attack from the flash crowd thus not punishing the legitimate flash traffic at any cause. In this paper, we propose a model which is an extension of existing novel framework and it is named as SADSD . This SADSD is Source validation And Detection with Service Differentiation which makes the suspicious users to prove their legitimacy whose web requests are delayed once it is detected that their signatures are bad signatures. Keyword :-Application Layer, CLOUD, DDOS, Flash Crowd, SADSD.
A New Algorithm For Secure Routing Protocols For Moble Adhoc Networks
Abstract: A mobile ad hoc network is a collection of wireless nodes that can be rapidly deployed as a multi- hop packet radio network without the aid of any existing network infrastructure or centralized administration. Therefore, the interconnections between nodes are capable of changing on continual and arbitrary basis. Nodes within each other's radio range communicate directly via wireless links, while those that are further apart use other nodes as relays. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Key Words: Cellular network, adhoc network, mobile network security.
Validation Over Basic Set Operations Of Internal Structure of MultiGranular Rough Sets
Abstract: The concept of crisp sets was extended to the new set which was introduced by Pawlak namely rough sets. Some of the reasons for such extension are to undertake modelling, reasoning and other computing like modelling imprecise data. Many extensions have been made in various directions in order to improve the modelling capacity of the general rough sets. Among the several extensions of rough sets multigranulation rough set model is one among that and found high level practical usage since it deals with multiple granules. Granules with more than one equivalence relation enrich the detail level in the defined equivalence relation. Several fundamental properties of these types of rough sets have been studied. Pawlak introduced the types of rough sets in as an interesting characterization of rough sets by employing the ideas of lower and upper approximations of rough sets. There are two different ways of characterizing rough sets. The accuracy coefficient and the topological characterization introduced through the notion of types. As referred by Pawlak himself, in general rough sets by knowing the accuracy of a set, it is still difficult to tell exactly its topological structure and also the present knowledge about the topological structure of the set gives no information about its accuracy. Therefore in practical applications of rough sets it is better to combine both kinds of information about the borderline region, that is of the accuracy measure as well as the information about the topological classification of the set under consideration. Keeping this in mind, Tripathy and Mitra [9] have studied the types of rough sets by finding out the types of union and intersection of rough sets of different types. Later Raghavan et al have extended these results to the multigranular context in [12]. The database based validation of union of two multigranular rough sets was carried out by Raghavan in [16]. In this paper I provided other basic set operations of internal structure of multigranulation rough sets supported with database based validation.
Integrated Software Application with Active RFIDs to Improve Process Efficiencies
Abstract: RFID is a tracking system that uses bar codes to track items in a store or organization. It helps to ensure operations are cost effective and efficient. Realizing the right value of each asset is critical in the supply chain process. Traditional methods involve significant time and resources to track and manage assets. Ensuring that the right type of RFIDs is used is important. Based on the organization context and need, right RFIDs can be put in use. Smart asset tracking allows businesses to know precisely where the assets are located and their movement in the process is tracked, as well as the asset’s physical and environmental condition. These intelligent systems form the foundation for silent commerce. This paper explains the use of integrated software application with active RFIDs. The features of the integrated software are discussed. The right use of these applications to improve the business process is also highlighted.
Edge detection of Grey Scale Images based on Multi-Structure Elements Morphology
Abstract: Edge detection is an important pre-processing step in image analysis. Conventionally, Mathematical morphology edge detection methods use single and symmetrical structure elements. But it is difficult to detect complex edge feature with these structure elements, because they are only sensitive to image edges which have the same direction of structure elements. This paper proposed a novel edge detection algorithm based on multi-structure elements morphology of eight different directions. We got five different edge detection results, then opening, closing, top hat transform and bottom hat transform is used to get final results. The experimental results showed that the proposed algorithm is more efficient for edge detection than conventional mathematical morphological edge detection algorithms and differential edge detection operators.
