Organic device modeling and application of organic transistors are rapidly emerging area of research now a day. This trend is developing due to various advantages of organic material offers such as fabrication over large area and flexible-electronics at lower-cost and temperature. Considering this fact, this paper presents overview of various OTFT structures. The result-analysis is implemented through...
In this paper the impact of the source/drain (S/D) electrode on performance parameters of the organic-material based transistor is discussed using the 2-D numerical-device Atlas simulator. Additionally, the performance-parameter and the electrical-characteristics of transistor is evaluated in terms of the drive-current, mobility and current on-off-ratio. Furthermore, thickness of source/drain electrode...
A stacked microstrip patch antenna with 2×2 array structure is being proposed in this paper. The antenna has four (2×2) rectangular radiating patch array on the top of FR4 substrate having air gap with ground plane. A coaxial probe feeding is located along the orthogonal axis of the array. The antenna is simulated using Ansoft HFSS. The designed antenna can excite six operating bands by double U-slot...
Micro electroporation (EP) devices with high efficiency and cell viability are useful for various biomedical applications, such as drug delivery and screening. However, these devices usually have low reliability due to undesirable electrochemical reactions. In this study, an Aluminum Nano-Spike EP (ANS-EP) chip was fabricated using nano-imprint lithography, electrochemical anodization and MEMS technology...
In the present work, an attempt has been made to analytically model the threshold voltage of short-channel optically controlled GaAs MESFETs with a vertical Gaussian profile. The two-dimensional (2D) Poisson's equation has been solved with suitable boundary conditions using superposition method to obtain an optical radiation dependent threshold voltage expression. The credibility of the model is established...
Industrial software user experience research tends to use more qualitative research in order to gain much knowledge about their users. There are number of analysis techniques originated from other domains like social science and psychology, available to analyse the qualitative dataset gathered during field studies. Human Computer Interaction researchers have tried and using some or combination of...
This paper presents a study on different techniques for stereo video compression using different view packing formats and benchmarking their performances. With “view packing” formats we intend the possibility to encapsulate in each single frame 2 views (Left and Right) together at lower resolution: in particular we will analyze the quality versus compression behavior of the following main packing...
Orthogonal frequency division multiplexing (OFDM) has several properties which make it an attractive modulation scheme for high speed wireless transmission links. In this paper, a novel power sharing technique is proposed for different users to improve the system performance. The proposed technique is based on use of variable amplitude of subcarriers (VAS). Power can be increased to the users who...
In today arena security critical real time applications running over clusters are growing rapidly. As an application running on clusters demand both timeliness and security, an efficient scheduling algorithm is needed that has better performance in terms of both number of task accepted and security value received.. In this paper the approach focuses on essential parameter i.e. Success ratio for a...
Providing people with a complete and responsive healthcare solution requires a multi-tiered health service delivery system. One aspect in the healthcare hierarchy is the need for care provided by nurses. Nursing care and observation provide the basis for nurses to communicate their practice with others in the healthcare system. It is necessary to capture and manage knowledge of nursing care to improve...
We present a novel arbitrary spatial downsizing method in H.264 to MPEG4 simple profile transcoder. Using median filtering and scaling of input H.264 4times4 block level motion vectors, downsizing module generates target resolution compatible 4times4 block level motion vector, which is fed at MPEG4 encoder to generate MPEG4 compatible final 16times16 or 8times8 block level motion vector. Downsizing...
We present a novel predictive statistical framework to improve the performance of an eigen tracker which uses fast and efficient eigen space updates to learn new views of the object being tracked on the fly using candid co-variance free incremental PCA. The proposed system detects and tracks an object in the scene by learning the appearance model of the object online motivated by non-traditional uniform...

Several groupware applications such as distributed databases, video conferences, distributed computation etc require secure transmission while communicating over open connected networks, and for which numerous group key agreement protocols for static/dynamic groups have been proposed for establishing a secret session key among the group members. This paper proposes ternary tree based new technique...
The novelty of the approach presented in this paper is the unique object-based video coding framework for videos obtained from a static camera. As opposed to most existing methods, the proposed method does not require explicit 2D or 3D models of objects and hence is general enough to satisfy the need for varying types of objects in the scene. The proposed system detects and tracks an object in the...
Nanocrystalline silicon (nc-Si:H) is an important material for solar cell applications. Thin films of nc-Si:H can be deposited cost-effectively using chemical vapor deposition (CVD) and sputter deposition. While CVD method offer higher deposition rate and is commonly used in PV industry, microstructural properties (such as hydrogen incorporation, crystallinity, surface morphology, dopant incorporation)...
An upconversion-based solar cell (UCSC) consists of a bifacial solar cell coupled to a spectral upconverter. This configuration has been suggested as a means of achieving solar cell efficiency beyond the Shockley-Queisser limit. In this paper an extended model of a UCSC is presented. This model adds to the capabilities of previously-reported models by considering a) non-radiative recombination; b)...
In this paper we report on the use of titanium dioxide (TiO2) films obtained through electrolytic deposition for dye sensitized solar cells (DSSCs). The deposition process consisted of two steps: deposition of titanium oxy-hydroxide films, and their heat treatment to get TiO2 films. Deposited films were studied using AFM, SEM, XRD, and UV-Vis spectroscopy. By sensitizing the films with Z709 dye DSSCs...
Video transcoding is becoming nowadays more and more popular, due to the necessity to cope with several different encoding standards, available bandwidth and decoder capabilities.
