Abstract: In this paper we have worked over the security issues for public key cryptanalysis for wireless network security .We have made an attempt to compare ECC and RSA for WIRELESS SENSOR NETWORKS. We found ECC to have a significant advantage over RSA as it reduces computation time and also the amount of data transmitted and stored. RSA key generation is much more time consuming as it requires the generation of large prime numbers. We also have made an effort to study the behavior of WSNs nodes.

Abstract: Red mud emerges as the major waste material during production of alumina from bauxite by the Bayer’s process. It comprises of oxides of iron, titanium, aluminum and silica along with some other minor constituents. In the present investigation experimental study was conducted for development of brick using red mud. Red mud brick of different trial mix were produced in the lab and test were conducted to find the properties of red mud brick properties found from tests were compared with the properties of ordinary bricks. It is found from the study that a red mud brick shows better performance than ordinary brick. As red mud bricks are eco-friendly & economical they protect the environmental also. Compressive strength of red mud bricks are more as compound to ordinary bricks. Water absorption is also more but within limit, change is size and weight losses of red mud brick are negligible in case of red mud bricks.

Abstract: The key motivation of this paper is to assess the factors which influence small and medium enterprises (SMEs) in a developing economy to adopt cloud computing. Recently, service providers offering a wide range of cloud-based ICT solutions to businesses have emerged into prominence. However, the acceptance and interest in these services amongst SMEs are slow and discouraging. As such, there is the urgent need to identify the enabling and constraining forces and other key influential factors necessitating this problem. The study highlights cost reduction on IT infrastructure and maintenance, improved communication, scalability and business continuity as the main drivers of cloud adoption, whereas lack of knowledge, poor internet connectivity, security of cloud services, lack of trust and interoperability with existing systems were identified as barriers to adoption. Top management support, trialability, competence of cloud vendors, resistance to new technology, compatibility and existence of IT infrastructure are realized as key factors influencing cloud computing adoption. These findings will go a long way in helping service providers and technology policymakers to develop solutions and strategies that specifically meet the needs of SMEs and other clients in order to encourage and speed up the rate of adoption.

Abstract: As the World Wide Web has grown, the next step of World Wide Web is web services. Web is the collection of services that interoperate with the help of internet. All the programmable materials are to be placed in the web sites which are accessed by others with the help of distributed nature of the network. The Universal Description, Discovery and Integration are used to describe, discover and integrate the relevant web services. Universal Description, Discovery and Integration are the distributed web-based information registries of web services. The information’s are described in the various domain Ontology and Generic Procedures. Web is alone not sufficient to describe the data because single web is not capable to carry all the information. Here, the word “Semantic Web” plays important role due to its property that is a combination of number of services. In this work Services are described via Web Service Description Language, Resource Description Framework and Ontology Web Language etc. in Semantic Web for better results. Further, the described Services in Knowledge bases are discovered with the help of schema matching algorithm. In this work schema matching algorithm is based on various different similarity measures. The modified architecture for the discovery of web services has also been presented in this work. After the description and discovery of web services, the integration of these services is required with the services offered by different-different business. The Composition methods are used for integrating these web services in this presented work. When the required services are discovered services are automatically integrated and provide the services to the customers. In this work semantic schema method has been used for the description, discovery and integration of web services. The new discovered services are also kept in the knowledge bases for the further future consideration. An experimental result has been also presented in this work which also shows that semantic schema matching is better than simple UDDI.

Abstract: Time synchronization is an important requirement for many services provided by distributed networks. A lot of time synchronization protocols have been proposed for terrestrial Wireless Sensor Networks (WSNs). However, none of them can be directly applied to Underwater Sensor Networks (UWSNs). A synchronization algorithm for UWSNs must consider additional factors such as long propagation delays from the use of acoustic communication and sensor node mobility. These unique challenges make the accuracy of synchronization procedures for UWSNs even more critical. Time synchronization solutions specifically designed for UWSNs are needed to satisfy these new requirements. This paper proposes Mobi-Sync, a novel time synchronization scheme for mobile underwater sensor networks. Mobi-Sync distinguishes itself from previous approaches for terrestrial WSN by considering spatial correlation among the mobility patterns of neighboring UWSNs nodes. This enables Mobi-Sync to accurately estimate the long dynamic propagation delays. Simulation results show that Mobi-Sync outperforms existing schemes in both accuracy and energy efficiency.

Abstract: In the past century, industrialisation and urbanization have created many environmental problems like air, water and soil pollution. As the result of soil desurfacing by brick kilns the soil fertility is affected. Increasing population and human interventions are responsible factors for environmental degradation. In the National capital region construction activity is on the peak and for this requirement for the bricks has increased many times. The focus of this study is to map and identify the desurfaced soils due to brick kilns in Jhajjar and Rohtak districts which lies in the NCR in the years 2007 and 2012. The desurfaced area of 2007 and 2012 is digitized and map is developed.

Abstract: Today in industry, 3-ph IM are being used at very wide scale. So its speed control according to specific requirement is very important. Also many times, 3-ph IM are to be operated with easily available 1-ph supply. For this, proposed mechanism of improving input power factor here is very efficient and reliable. At input terminal, high performance Two Stage Interleaved Power Factor Correction technique (IPFC) with boost topology operating with discontinuous current conduction is used. With this circuit, 3rd order harmonics can be eliminated upto completely from the input supply. Also it will help to achieve almost UNITY pf with rated power supply. With this type of 3-ph supply provided to the IM, Reactive power generation can be minimised which leads to efficient control over the wastage of Reactive power and use of Reactive power compensation techniques. So the overall cost of operating 3-ph IM can be minimised.

Abstract: This study seeks to assist people in rural areas of Bangladesh by proposing sustainable methods which implement affordable and durable adobe bricks for construction. Adobe one of the oldest building materials in the world, is strong when dry but lacks structural integrity when exposed to moisture. Chemical additives such as cement and natural rubber latex are added into the adobe mixture to protect the brick against moisture decomposition. Once the chemicals are added and the mixture is formed into a brick, a stabilized adobe brick is formed. The tested brick mixes, measured by volume were 1:1:1 (Soil: Fine Sand: Cement) with natural rubber latex 0, 01, 02, 03, 04, 05% (by wt of water). After testing these bricks by water jet, submersion, Water absorption, modulus of rupture and compression, 1:1:1 soil, fine sand, cement with natural rubber latex 05% proved to be viable options for economical and durable bricks. This study explores that cement and natural rubber latex in adobe brick effects optimum compressive strength and low water absorption. The results provide a guideline for producing adobe brick containing cement and natural rubber latex with improved compressive strength and low water absorption. Adobe brick with performance improved in this ways will be beneficial for developing low cost architecture for local people and for building hotels and recreation facilities for the tourism industry.
Keywords: Chemical additives, water jet, submersion, Water absorption, modulus of rupture.

Abstract: This paper describes design and analysis of composite mono leaf spring. Weight reduction is now the main issue in automobile industries. In the present work, existing mono steel leaf spring of a light vehicle is taken for modeling and analysis. A composite mono leaf spring with Carbon/Epoxy composite materials is modeled and subjected to the same load as that of a steel spring. The design constraints were stresses and deflections. The composite mono leaf springs have been modeled by considering Varying cross-section, with unidirectional fiber orientation angle for each lamina of a laminate. Static analysis of a 3-D model has been performed using ANSYS 12.0. Compared to mono steel leaf spring the laminated composite mono leaf spring is found lesser stresses and weight reduction of 22.5% is achieved.
Keywords: Composite leaf spring (LCLS), Static analysis, Carbon/Epoxy, ANSYS 12.

Abstract: Weight reduction is the prime focus of automobile manufacturer. In automobile leaf spring is potential item for weight reduction which accounts for 10-25 % of unsprung weight. Material with maximum strength and minimum modulus of elasticity is most suitable for leaf spring, and composite spring reduces weight of automobile without reducing the load carrying capacity. In present project work comparative analysis of c-glass/epoxy composite leaf spring and steel leaf spring is done by analytical, FEA using ANSYS 12. The result of FEA is also experimentally verified. Study demonstrates that the composite can be used for leaf spring for the light vehicle and meet the requirement, together with the sustainable weight reduction. The stresses induced in the C-glass/Epoxy composite leaf spring are 69% less than that of the steel spring nearly. This study leaves wide scope for future investigations. It can be extended to newer composites using other reinforcing phases and the resulting experimental findings can be similarly analyzed.

Abstract: Reinforced concrete is the principal material for military engineering and nuclear power plant containment. Reinforced concrete slabs are used in floors, roofs and walls of buildings and as the decks of bridges. The floor system of a structure can take many forms such as in situ solid slab, ribbed slab or pre-cast units. By providing torsion reinforcement, corners are usually prevented from being lifted up. In such cases the corners have to be suitably reinforced at top and also at bottom otherwise cracks are liable to be formed at the corners. The present investigation is intended to study the influence of torsion reinforcement in reinforced concrete slab with end condition all ends discontinuous under uniformly distributed load. Slabs with torsion reinforcement varying from 0% to 30% were casted and tested. Increasing in the torsion reinforcement controls the deflection of the slab element. As the torsion reinforcement increases the corners are being held down. At the maximum of 30% of main reinforcement was provided as torsion reinforcement corners are not held down completely and there is a considerable decrease in central deflection also.

Abstract: Optical Character Recognition (OCR) is the mechanical or electronic translation of images of handwritten or typewritten text (usually captured by a scanner) into machine-editable text. The main aim of this project is to design an expert system which will be best to, “Optical Character Recognition” that effectively can recognize a particular character of type format using the Feed Forward approach. OCR is a field of research in artificial intelligence, in pattern recognition and also in machine vision. Though academic research in the field that continues, the focus on OCR has been shifted to implementation of proven techniques. Optical character recognition (using optical techniques such as mirrors and lenses) and digital character recognition (using scanners and computer algorithms) were originally considered as separate fields. Because a very few applications survive that use the true optical techniques, the OCR term has been broadened now to include digital image processing as well. This system will be applicable of recognizing any number of characters including uppercase, lowercase alphabets and numerals.
Keywords: Optical Character Recognition, Feed Forward Networks, Image Processing, Artificial Intelligence.

Abstract: Dental implant is used to hold the artificial tooth into its proper position in human jaw. It serves the purpose of natural root which is there in natural tooth. Most of the dental implants are parallel or slightly tapered in shape but not as tapered as the natural roots. But due to some space and accessible constraint, it is not possible to provide taper same as that of the natural root. Failures of implant–abutment connections are relatively frequent clinical problems. So there is a need of analysis of dental implant abutment. For that research has been done on the existing design with its limitation. This paper focuses on Analysis and techniques used for evaluation of Dental Implant.
