Title : Joint strength analysis during vibration test of spacecrafts Authors : Alok kumar, Laxamanachary M
Abstract : vibration test on spacecrafts are carried out to simulate the launch environment and measure the response of all the components of spacecraft as per the specification profile in terms of frequency range and g level that will be experienced by them during launching. To vibrate the spacecraft at required g level, vibration shakers of different capacities are used. To perform the test, the spacecraft should be rigidly mounted on top of the shaker through a fixture to transfer the same amount of force as generated by the shaker. For mounting of spacecraft different sizes of bolts can be used at different PCDs. But strength of those bolts should be enough to withstand the large force that will be encountered during vibration test. Force acting on the bolts depends on various factors such as mass of the specimen, g level, Center of Gravity (CG) height of specimen, Pitch Circle Diameter (PCD) of bolts etc. In this paper strength of joint has been analyzed to calculate the safe value of test parameters for a given shaker system. It must be noted that the numbers of bolts used for mounting are in multiples of four and are symmetric in all four quadrants.

Title : ADVANCED EMBEDDED SYSTEM DESIGN IMPLEMENTATION IN ARTIFICIAL INTELLIGENCE Authors : Abhineet Sinha, Vishal Kumar
Abstract : The technology of programmable matter or catoms is one of the most revolutionary concept in the history of electronics and computers. Developed by researchers Seth Goldstein and Todd Mowry the field of claytronics is all set to replace Nanotechnology from the origin of electronics. The catom is known to be an individual modular robot which works in groups of millions to provide fictional properties such as color changing or shape changing according to their corresponding catoms. Due to this property of catoms it offers dynamic physical rendering that result in these tiny micro-robots to change any shape depending on their environment. Due to the availability of millions of catoms in a single ensemble it is very difficult to have a global planning system to control all these robots. Hence the scientists are trying to find a way enabling the catoms to change shape without having a global planning system.

Title : ENHANCEMENT OF WEATHER DEGRADED IMAGES WITH IMPROVISED ALGORITHM Authors : Miss Pooja Sharma, Dr. Savita Shiwani
Abstract : In this paper, reported algorithms for fog and rain removal are reviewed. Fog reduce the visibility of scene and thus performance of various computer vision algorithms which use feature information. Formation of the fog is the function of the depth. Estimation of depth information is under constraints problem if single image is available. The algorithm helps to devise the system which removes rain from images and videos and to improve the various vision- based algorithms. Rain is a noise that impairs videos and images. Such weather conditions will affect stereo correspondence, feature detection, segmentation, and object tracking and recognition. In video surveillance if any problem is found due to weather conditions the object cannot be tracked well.

Title : Mathematical Modeling of a Transverse Shear Deformation Thick Shell Theory Authors : MOHAMMAD ZANNON, MOHAMAD QATU
Abstract : Three-dimensional theory (3D) of elasticity in curvilinear coordinates is employed to understand the stress and strain distribution in the middle surface of a thick composite shell under various operating conditions. The equations of motion are derived by making use of the relationships between forces, moments and stress displacements of shell using Hamilton’s principle of minimum energy. The necessary theoretical assumptions are discussed to simplify the three dimensions to a set of two-dimensional (2D) shell equations without violating the theory of elasticity. Displacement through the thickness is of third order in this analysis as compared with the first order approximation as previously published research. Equilibrium equations are formulated using these equations to achieve a set of linear partial differential equations and solved for exact solutions using Fourier series expansion for simply supported laminated cross-ply boundaries. This solution can be further used for various vibration analysis and optimal design of thick shell structures. Finally, the new additional parameters using the third order shear deformation of thick shell theory obtained from Fourier expansion is compared with the first order shear deformation shell theory from the literature.

Title : Free Vibration Analysis of Thick Cylindrical Composite Shells Using Higher Order Shear Deformation Theory Authors : MOHAMMAD ZANNON, MOHAMAD QATU
Abstract : This paper presents a free vibration analysis of laminated cylindrical shells using higher order shear deformation theory recently developed by Zannon et al., (2014). Equilibrium equations of motion, stress resultants and strain displacement relations are developed using Hamilton’s principles. These equations are based on the theory of elasticity with terms truncated to a third order (hence, third order theory). The equations can be used to characterize the system under various boundary conditions. For the present analysis, the boundary conditions considered are simply supported with a cross-ply lamination sequence. Here, we specifically developed mathematical formulation that considers transverse normal stress, shear deformation and rotary inertia for the shell system. The free vibrational analysis using the third -order shears deformation shell theory led to a system of generalized eigenvalue problem. This eigenvalue problem is then solved numerically using commercial Matlab software to obtain the free undamped vibrational frequencies. Since the higher frequencies are often damped, the first five natural frequency parameters are reported and compared with previously published first order approximation and three dimensional finite element analyses.

Title : Kinematic Analysis of Ultimate Stride Length and Take-Off of Fosbury Flop High Jumpers Authors : Ch. Raja rao, Prof. Y. Kishore, Dr.J.Ramamohan Rao
Abstract : The Fosbury Flop high jump technique consists of a run up, take-off, flight and landing. Among these four phases the take-off is the key to performance. The run up will influence take-off technique and body movements in flight. Therefore the final stride of the run up is the transitional phases connecting the run up and take-off. Many studies have measured the take-off parameters of high jumpers in competition situations. These measurements will provide useful feed back to the coach as well as high jumpers. The purpose of this study was to analyze kinematic variables of take-off i.e. the movement time of different phases of take off and knee and approach angles of final stride of the run up of three top junior state level athletes of Andhra Pradesh using the Fosbury Flop technique. METHOD: Three male high jumpers were filmed through two Panasonic-AG-DVX-102B,F11 sensitivity, high image quality, camcorders during their competitive performance in the Andhra Pradesh inter district junior athletics championship from 6th July to 8th july,2012 held at GMC Balayogi athletics stadium, Hyderabad, India. The best valid and failed jumps were taken from each fosbury flop athlete for the analysis used by the quintic biomechanics 9.03 V 17 (motion analysis). The kinematic variables which were selected in the study were 1) Reaction and movement time of last stride and the instant the take-off 2) Knee and approach angles of last stride and the instant take-off. Collected data were analyzed by t test for comparison of the kinematic parameters between successful and unsuccessful jump. A level of significance was set at 0.05.RESULTS: This study indicated that all the three jumpers who have used the fosbury flop technique have shown insignificant differences on the variables tested. CONCLUSION: In this study data was collected only on two variables of take off. i.e. speed and angles. The standing height and leg lengths were also collected. However, to establish the relationship between the anthropometric measurements of the athletes and the performance, there is a need to obtain more data of the athletes participating at different levels of competitions.

Title : A MPPT with Fuzzy Sliding Mode Control for PV System used in Battery Charging Applications Authors : P.Amuthini, M.Preetha, M.Yuvaleela, E.Mageswari
Abstract : DC-DC power converters are added for matching the load to the photo voltaic modules (PVM) because of the nonlinear behavior of the photo voltaic (PV) cells. A maximum power point tracker (MPPT) for PV cells, PVM and PV arrays are presented using a dynamic optimal voltage estimator to estimate the voltage at which a PV cell generates its maximum power and the dynamic voltage estimator force the PV cell to reach and operate at that voltage in a finite time and to stay there for all future time so that the maximum power is available to the load. This is obtained by controlling the duty cycle of a DC-DC converter using Fuzzy sliding mode control (FSMC). The load will be composed of a battery bank. A sliding mode controller is given the estimated maximum power point as a reference for it to track that point and force the PV system to operate in this point. This method has the advantage that it will guarantee the maximum output power possible by the array configuration while considering the dynamic parameters such as temperature and solar irradiance and delivering more power to charge the battery. FSMC is designed and simulated using MATLAB/SIMULINK environment. The simulation results show that the maximum power is obtained from PVM at all the operating conditions using FSMC.

Title : Integration - the Item of Ultimate Concern on the CONTINENTAL & ODL Development Agenda – a philosophical point of view Authors : Jameson Kurasha, Chrispen Chiome
Abstract : The setting in Africa since the 15th Century is characterised by divisions, social tensions and political struggles. Natural conditions have also contributed to the plight. Most problems however, are interpersonal and moral. What seems to be evident is that African nations on their own cannot, independently, manage the challenges hence the call for unity and specifically continental integration. Integration faces cultural obstacles. How can a nation like Namibia integrate with Egypt where 600 citizens were sentenced to death, apparently without any hearing? How does the project incorporate a group which kidnaps over 200 girl children for religious purposes? How can African economies, diverse as they are, be melded into one? As of 2011, the IMF’s World economic outlook database showed that the GDP levels of African nations ranged from 408 billion dollars to 0.25 billion dollars. How do we form an average economy out of nations that have such varying poverty levels? Data also reveals the fact that poverty rates across African nations span from 3% to 84%. So, the economist hastens to ask, “How one can integrate such vastly different economies?” The paper defines its conception of integration by pointing at nations that are already integrated such as USA. The sceptic’s question; whether, integration is possible or not is, explained positively. Philosophical tools are cited and discussed - with African philosophical theories such as Hunhuism/Ubuntuism getting considerable attention. The conclusion is that continental integration is a good idea and that Open and Distance Learning is the ideal vehicle to promote it. The methodology employed is eclectic and sources are generally classical.

Title : A Comparative Study of Simulation Tools for Distributed Environment Authors : Ms. Rupal D Bhatt, Dr. D.B.Choksi
Abstract : Clusters, grids, and peer-to-peer networks have emerged as popular paradigms for next generation parallel and distributed computing systems. They enable usage of distributed resources for solving large-scale problems in science, engineering, commerce and other domains. The common approach adopted by these systems is to employ scheduling heuristics that lead to an optimal schedule.
Scheduling diverse applications and resources in distributed environment is challenging because target resources may be heterogeneous and their load and availability varies dynamically. Moreover, independent tasks may share common data files. Unfortunately, it is often impossible to obtain analytical results to compare the efficacy of these heuristics. Given the nature of most scheduling problems one must resort to simulation to effectively evaluate and compare their efficacy over a wide range of scenarios.
This work describes the Grid and cluster scheduling simulators for study, testing and evaluation of various job scheduling techniques. We present a comparative study to highlight the usefulness of various simulators like GridSim, ClusterSim, SimGrid, Alea 2, BeoSim and Bricks for conducting scheduling research. An attempt is made in this paper to provide the basis for appropriate selection and possibility of designing new scheduling algorithms offering better performance and throughput using existing Grid and cluster scheduling simulators aimed at improvement in the performance of distributed systems.

Abstract : The internet and digital devices like portable media players, smart phones and digital cameras are now being used by many different people for a variety of reasons. Unfortunately, criminals are also designing their own uses to assist them in committing their crimes. As with most new technologies cloud storage services have the capacity to be used for criminal exploitation and to form the basis of civil litigation. As such those working in both digital forensics and eDiscovery must have the capability to forensically analyze these storage platforms.
The storage as a service (StaaS) cloud computing architecture is showing significant growth as users adopt the capability to store data in the cloud environment across a range of devices. Cloud (storage) forensics has recently emerged as a salient area of inquiry. Nowadays with using a widely open source cloud StaaS application, researcher will document a series of digital forensic experiments with the aim of providing forensic researchers and practitioners with an in-depth understanding of the artifacts required to undertake cloud storage forensics. This research will focus upon possible artifacts, which will categories the potential evidential data specified before commencement of the experiments. In this research, researchers will try to find a number of digital forensic artifacts as part of the experiments that will be used to support the selection of artifact categories and provide a technical summary to practitioners of artifact types. Finally general guidelines for future forensic analysis on open source StaaS products and recommendations for future work will be proposed.

Title : The problem of oversaturation of computer systems with applications and its supposed solution Authors : NAZOKAT ABDULLAEVA, FARKHOD TASHPULATOV
Abstract : In the given paper, an idea about integration licensed computer programs into one address space to use their shapes in workstations is considered. The key moment of this idea is work with interface of software without its installing into a workstation. As a result, not only users are free from problems on setting up applications into their PCs, notebooks, pads and mobile phones but also resources of their devices can be loaded more rationally. The conception is a very topical because nowadays the tendency of oversaturation of computer systems with software is observed. Meanwhile, majority of used programs are either copies of licensed software or their counterfeits. Besides, we ourselves experience constantly a problem related supersaturation of workstations with tremendous amount of installed applications which automatically integrated to a client side of a distributed system by us. Therefore, we firmly believe, that results of our research could be improved essentially if we realized this idea.

Title : Multilevel Inverter Topology with Reduced Number of Switches Authors : D Sai Krishna, M. Harsha Vardhan Reddy
Abstract : Nowadays, multilevel inverters are having wide range of applications. Researchers are also well concentrated on investigating of various topologies for multilevel inverters with less number of switching devices, power supply units and also with fewer harmonic too. In this paper a new multilevel inverter topology is proposed, by which we can generate “6n-5” output levels by using “n” number of capacitors. This proposed topology requires bi-directional switches, one-directional controlled switches, and capacitors. This paper provides a new topology with less number of switches and a single dc source, more number of output levels as compared to conventional multilevel inverters. To validate the proposed topology, MATLAB based simulation analysis and hardware prototypes are carried out.

Title : Pre-monsoon physico - chemical analysis of surface water of Jashpur District Chhattisgarh (C.G.) Authors : Rajiv Ratna Pandey, Dr. M.R. Augur
Abstract : Water samples were collected from two sampling station viz., station 1 Dhondidand and station 2 Dhondibahar of Ib river of Jashpur district in Chhattisgarh state during March 2013 to June 2013. The samples were subjected to laboratory analysis using atomic absorption spectrophotometer (AAS) to assess the levels of heavy metal such as Chromium (Cr), Cadmium (Cd), and Nickel (Ni). Standard procedures (including on site analysis) were used to determine the physicochemical parameters such as Temperature, pH, Turbidity, Alkalinity, Total Dissolved solids (TDS), Dissolved oxygen (DO), Sulphate, Fluoride and Total Hardness of the river water samples. The ranges of values of the observed parameters were Temperature (21.4-28.3) 0C; pH : (7.22-7.82); Turbidity : (2-6) NTU; Alkalinity : (5-11) mg/l; Total dissolved solids : (30-38) mg/l; Dissolved oxygen : (4.4-5.0) mg/l; Sulphate : (5.8-7.9) mg/l; fluoride : (0.25-0.53) mg/l; Total hardness : (23-29) mg/l. All the values were within the WHO, WHO/UNICEF and the USEPA guidelines. The values of these parameters indicate that Ib river is moderately not polluted.

Title : RECOGNITION OF DEGRADED PRINTED GURMUKHI NUMERALS Authors : Nishu Goyal, Seema
Abstract : Character recognition is one of the important subjects in the field of Document Analysis and Recognition. Character recognition can be performed on printed text or handwritten text. Printed text can be from good quality documents or degraded documents. The performance of any OCR system heavily depends upon printing quality of the input document. Little reported work has been found on the recognition of degraded Gurmukhi numerals. In this dissertation we have recognized consider already isolated printed numerals on which we apply binarization techniques. Gurmukhi numerals in which we have considered various types of printed degradations like broken, background noise problem, heavily printed and shape variant characters. This work is performed over 10 Gurmukhi numerals only. The numerals are broken we have corrected the broken numerals up to 5 pixels broken distance. So, in this dissertation we have used structural and statistical features like Zoning, Transition features, Distance Profile features and Neighbor pixel zone etc. for generating feature sets that are used for recognizing printed Gurmukhi numerals by using SVM and Parameters used for testing have achieved maximum accuracy of 92% approximate, Squared Correlation Coefficient to get out results with 0.93 approximate with combined techniques (GRAD+ZCI+ZCZ), feature vector (F8) but Mean Square Ratio is less in Zoning Centeriod Zone Technique (ZCZ), feature vector (F7) in the four training tested formats even or odd and first half or last half and vice versa samples using SVM.
