Autism Spectrum Disorder is characterised by the defects in communication and social skills. This is the neuro developmental disorder, that is, the disorder in brain and its functioning that affects the emotion, communication, self-control and person's ability to learn by stopping the growth and development of the central nervous system. A number of studies have been made to find the accurate features...
The design and implementation of a pulsed current drive for a high power Laser Diode has been presented. The single-stage SMPS does not use any linear regulator, and is able to pump upto 50A in a 2V laser diode or in two laser diodes in series for a maximum of 4V output with an achievable rise and fall times of around 80 µs. Various protections to safeguard costly and sensitive Laser Diode have been...
Communication among the wireless links between mobile nodes is become popular research area because of its simplicity of deployment and mobility. Collection of all mobile nodes through which all wireless links are connected called as Mobile Ad hoc Network (MANET). MANET network gets too much attraction of researchers due to its mobility, reliability, self-repairing, dynamic infrastructure and independent...
This paper aims at rainfall forecasting which has been one of the most challenging problems around the world. Rainfall forecasting has importance in different areas including scientific research, agriculture etc. A Bayesian network model is proposed in this paper for forecasting monthly rainfall at 21 stations in Assam, India. Bayesian network or belief network (BN) is a probabilistic graphical model...
Current modern wireless communication is based on orthogonal frequency division multiplexing (OFDM) and the reliability of it significantly increased with the multiple inputs multiple outputs (MIMO), and there is a scope to enhance the performance of the system further. Working on the same goal this paper proposed a methodology to enhance end to end performance of the system. The projected methodology...
This paper investigates the multiple input multiple output (MIMO) space-time coded wireless systems. MIMO-OFDM system is improving the reliability of the WiMAX (IEEE 802.16). This paper discusses the modeling of MIMO-OFDM using MATLAB R2012b version. This model is a using tool for BER (Bit Error Rate), PAPR (Peak Average Peak Ratio) and transmits spectrum performance evaluation for signal & multiple...
Passwords are the main and most common method of remote authentication. However, they have their own frustrating challenges. Users tend to forget passwords that are chosen to be hard to guess. Password managers are an approach to keeping our passwords safe. However, they mainly rely on one master password to secure all of our passwords. If this master password is compromised then all other passwords...
The basic objective of this paper is to analyze the concept of wavelet based algorithms for image compression using different parameter. All algorithms are based on still images, The algorithm involved in the comparative analysis is Wavelet Difference Reduction (WDR), Spatial orientation tree wavelet (STW), Embedded zero tree wavelet (EZW) and modified Set Partitioning in hierarchical trees (SPIHT)...
This study establishes the feasibility of using computer-based EEG recognition system to monitor anesthetic depth during halothane anesthesia. Experiments were carried out on ten dogs, at different levels of halothane, recording four channels of EEG data. The anesthetic state of the patient was tested using a tail clamping stimulus. A tenth order autoregressive (AR) model was used to represent the...
