A Comparative Study of Psychological Factor Among Female Athletes
Psychological needs play an important role in the promotion and demotion of tension, because any type of tension provide frustration and these frustrated needs leads towards aggressiveness in the individual, need of direct gain, power, and prestige, need for resolving ambiguous cries and for group belongingness and conformity are the main needs which appear to be of utmost importance. The most of the tensions are due to physical, social, cultural, religious, economic, political and psychological cause, and the stability of the tension has been found to be due to high competition, lack of common goals, lack of contacts, value conflict, ignorance, partiality, prejudices, conformity, and maladjustment and to achieve dominance by someone. The objective of this paper is to study to measure different kinds of tension viz. communal tension, caste tension, and religious tension cultural tension regional tension and language tension. For this purpose Fifty female athletes of age group 18-25 participated in south-west zone inter-varsity tournament of respective sport viz judo, badminton; table tennis, wrestling, swimming, and athletics, during 2007-2008 were selected as subjects for this study at random.

Effect of process parameters and VC content on structural and mechanical properties of WC-20Co nano composites
58-66The effect of process parameters and vanadium carbide on hardness, toughness and structural properties of the tungsten carbide-cobalt (WC-Co) nanocomposite has been investigated using micro-hardness tester, X-ray diffraction and scanning electron microscopy (SEM) with attached energy dispersive spectroscopy, respectively. To suppress grain growth, a high percentage (upto 10 wt. %) of vanadium carbide (VC) has been taken as a grain growth inhibitor as well as a hardener. WC-20Co composite with 7.5 wt% VC, heat treated at 1100 °C holding time for 2 hours, possesses high hardness (1687 HV) when the volume fraction of tungsten carbide (WC) and Co6W6C phases have been taken in the ratio of 2:1. High hardness and toughness have been obtained at 1100 °C for 2 h heat-treated sample. High VC content with 8 h holding time has increased the porosity in the samples
Diversity in attachment devices of aquatic insects in a torrential hill stream of mid Himalaya
Present study was carried out to explore the morphological attachment devices od seven aquatic insect larvae or naiads (representing four orders of Ephemeroptera, Plecoptera, Trichoptera, and Hemiptera) along the swift water current of Binwa, a mid-Himalayan hill stream using scanning electron microscopy (SEM) images. Water current showed direct relation with slope/gradient and volume of water in stream. Samples were collected at four sites located at different attitude along the stream. The collected larvae or naiads have many morphological features, including adhesive pad, friction pad, serrated tarsal claw, bifid tarsal claw, tarsal claw with clamp, sucker, and serrated spines which serve as their adaptations for the fast-flowing waters. Principal Component Analysis revealed the importance of water current for assemblage and abundance of these aquatic insects, as it directly related to TDS, electric conductivity, turbidity and nutrients level in stream water, and cumulatively affect these aquatic macroinvertebrates. Similarities in structures of different species suggest the convergent evolution, while slight differences inferred as specializations for species specific niche of these organisms in stream habitat
Modeling and Simulation of Non-Classical MOSFETs for HP and LSTP Applications at 20 nm Gate Length
The endless miniaturization of Si-based Metal Oxide Semiconductor Field-Effect Transistors (MOSFETs) has the key for urging the electronic uprising. How-ever, scaling of the channel length is the enormous challenge to preserve the per-formance in terms of speed, power, and electrostatic integrity at each technologynodes. From the commencement of CMOS scaling, the simple planar MOSFETs are not up to the performance because of the increased SCEs and leakage cur-rent. To slacken the SCEs and leakage currents, different types of structures i.e.Multi-Gate MOSFETs like double-gate (DG), triple-gate (TG), FinFETs have in-troduced in the literature. Fully Depleted (FD) Silicon-On-Insulator (SOI) devices have shown potentially significant scalability when compared to bulk MOSFETs.In spite of, the introduced structures in literature are not offering concurrent SCE repression and improved circuit implementation. And some involve tangled processing not suggested for smooth integration into the here and now CMOS technology. The scaling capability of nanoscale ultra-thin (UT) silicon directly on insula-tor (SDOI) single gate (SG) and DG MOSFETs is investigated to overcome SCEs and improve power consumption. Dependence of underlap length on drain cur-rent, Subthreshold Slope (SS), transition frequency, delay, Energy Delay Product (EDP), etc. is studied for DG MOSFET and FinFET, to find the optimum value of underlap length for low power consumption. DG MOSFET is an excellent can-didate for high current drivability whereas FinFET provides better immunity toleakage currents and hence improved delay, EDP over DG MOSFET. Furthermore,FinFET provides a high value of transition frequency which indicates that it is faster than DG MOSFET. III-V channel materials are proposed for the discussed two structures to improve the On current at the same integration density as in Si-based channel FETs. The role of geometry parameters in sub 20 nm SOI Fin-FET is studied to find the optimum value of height and width of Fin for analogand RF circuit design. This work provides the influence of the height and width of Fin disparity on different performance matrices that comprises of static as well as dynamic figures of merit (FoMs). Based on the Aspect Ratio (WF in/HF in),the device can be divided into three parts, i.e., FinFET, Tri-gate, and PlanarMOSFET.CMOS for SG and DG is made using the combination of NMOS and PMOS by engineering the work function in order to have same threshold voltage for N-channel and P-channel MOS. The inverter is without doubt the core of all digital applications. Once its operation and characteristics are understood with clarity,designing more complicated structures such as NAND gates, multipliers, adders, and microprocessors are significantly explained. The performance of CMOS is articulated. All the dimensions are according to the ITRS 2013 datasheet. Thework provided here is requisited to give the purpose for forward experimental in-vestigation
Video Inter-frame Forgery Detection Approach for Surveillance and Mobile Recorded Videos
We are living in an age where use of multimedia technologies like digital recorders and mobile phones is increasing rapidly. On the other hand, digital content manipulating softwares are also increasing making it easy for an individual to doctor the recorded content with trivial consumption of time and wealth. Digital multimedia forensics is gaining utmost importance to restrict unethical use of such easily available tampering techniques. These days, it is common for people to record videos using their smart phones. We have also witnessed a sudden growth in the use of surveillance cameras, which we see inhabiting almost every public location. Videos recorded using these devices usually contains crucial evidence of some event occurence and thereby most susceptible to inter-frame forgery which can be easily performed by insertion/removal/replication of frame(s). The proposed forensic technique enabled detection of inter-frame forgery in H.264 and MPEG-2 encoded videos especially mobile recorded and surveillance videos. This novel method introduced objectivity for automatic detection and localization of tampering by utilizing prediction residual gradient and optical flow gradient. Experimental results showed that this technique can detect tampering with 90% true positive rate, regardless of the video codec and recording device utilized and number of frames tampered
Element Free Galerkin Post-processing Technique Based Error Estimator for Elasticity Problems
The study present a Mesh Free based post-processing technique for asymptotically (upper) bounded error estimator for Finite Element Analyses of elastic problems. The proposed technique uses Galerkin Element Free procedure for recovery of the displacement derivatives over a patch of nodes in radial domains. The radial nodes patches are used to construct the trial shape functions utilizing the moving least-squares (MLS) techniques. The proposed technique has been tested on three benchmark elastic problems discretized using 4-node quadrilateral elements. The recovered nodal stresses are utilized to calculate the error in finite element solution in energy norm. The study also demonstrates adaptive analysis application of proposed error estimator. The performance of proposed error estimator based on mesh independent node patches has been compared with that of mesh dependent node patches based Zienkiewicz-Zhu (ZZ) error estimator on structured and unstructured mesh. The improved results of the proposed error estimator in terms of convergence rate and effectivity are obtained. It is shown that present study incorporates the superiority of the Mesh Free Galerkin method into finite element analysis environment
