With rapid growth in today’s technology, digital communication is playing a major role to provide hostile environment to meet various applications. In this communication, Coding plays a prominent role to contribute error free transmission through channel coding which improves capacity of a channel by adding some redundant bit to the original information. One way to provide a better performance of the communication system is by concatenating different types of channel coding techniques. The concatenation can be done either in parallel or serial. The primary aim of this paper is to concatenate the Reed-Solomon codes with Convolutional codes in series, which provides better results comparing with single coding techniques. The performance of the concatenation of Reed-Solomon codes with Convolutional codes can be evaluated by finding bit error rate with various values of signal-to-noise ratio over AWGN channel. The analytical result has been obtained by using MATLAB/OCTAVE.
Abstract\nThe present study evaluates the efficacy of vitamin C in combating phorate induced oxidative stress and cellular damage in hepatic cells of mice, in vivo. Mice were simultaneously treated intra-peritoneally with phorate, either in single (1mg/kg bw) or double (2mg/kg bw) dose and with vitamin C (500mg/kg) for 3 and 7 days, respectively. Several biomarkers like chromosomal aberrations, micronuclei and sperm head anomalies, DNA fragmentation assay, and enzymatic parameters, namely, LPO, total thiol content, AST, ALT, LDH and GGT along with histopathology of liver tissues were studied. Overall results suggest that vitamin C showed amelioration in phorate intoxicated mice, therefore, has potential for therapeutic use in the management of phorate induced toxicity.
IoT is continuously one of the hottest areas that are developing at a fire speed, where all things which are used in regular life connected with the internet and can be monitored and can be operated remotely. IoT has many applications in all domains, one of the wonderful applications is in agriculture domain. Monitoring of environment parameter is very essential for maximizing the yield. In particular, monitoring various agriculture parameters such as temperature, moisture, humidity, Ph value of soli and along with other parameter which affect the crops. A traditional way of measuring these agriculture parameters means manual measurements, monitoring them at various levels and at different times. This paper deals with remote monitoring system based on IoT protocol used by different researchers to increase agriculture production and optimal utilization of resources along with the proposed system which is useful in monitoring data.
Methods of compressing the data prior to storage and/or transmission are of significant practical and commercial interest. Considerable amount of research has been devoted in the last two decades to tackle the problem of image compression. Image compression addresses the problem of reducing the amount of data required to represent a digital image. The underlying basis of the reduction process is the removal of redundant data. From a mathematical viewpoint, this amounts to transforming a 2-D pixel array into a statistically uncorrelated data set. The transformation is applied prior to storage or transmission of the image. At some later time, the compressed image is decompressed to reconstruct the original image or an approximation of it. In this work discrete wavelet transformation is used to compress the images. It is found that the inherent features of discrete wavelet transform have advantages over the discrete cosine transform which make them a better tool for image compression by providing higher compression ratio without affecting much the quality of the reconstructed image.
HRD is a dynamic field of study captures the attentions not limited to management, business and social sciences, but, also attracting attentions of scientists, priests, meditators, humanists, practitioners and professionals and many more. The multidisciplinary contributions to HRD field and to the conceptual repositories have enforcing HRD a greater way for its paradigm change due to recent concentrations and emergences of Quantum Physics, Meta-physics, Neuro-physics, Psychopathology, Quantum-Psychophysiology, Neuro-quantology, Cognitive innovation and Bio-Vitalism. This emerging paradigm of HRD is helping in setting up age breaking rules and regulations by the evolving change in boundary, pattern, and the edge of thinking. \n\nHere, I articulated the quantum analogies, application of theory of unified field with the potential of application in HRD activities and strategies. Articulating the quantum analogies for future HRD application with the help of existing work of quantum mechanics could shape the conceptual map of Quantum based HRD process in confronting future challenges for HRD limitations of emerging practices.
This article focuses on the mobile-based learning of English language vocabulary. It also investigates whether the use of mobile during studies promotes student‟s learning of English language vocabulary. This research was conducted with 40 male EFL learners of 18-30, studying at Islamic Azad University (IAU)of Shiraz branch. To determine its homogeneity, the researcher performed a proficiency test. They were divided into control and experimental groups. The experimental group was presented with the treatment which was having and making use mobiles during the class, while working on memorizing words and its meanings as well as sentences in which the vocabularies were used, while the control group was given no treatment, but they were allowed to use dictionary. It was continued for two sessions a week, and four weeks per month. A T-test was administered to show the possible differences available between the two groups. It was understood that the students memorized and remembered significantly more words while they used mobile.
Aluminum nitride (AlN) is selected for microwave dielectric measurements in frequency ranges, 615 MHz, 1412 MHz, 2214 MHz, 3017 MHz and 3820 MHz at temperatures range from 25℃ to 2000℃. The structural characterizations of this sample before and after the microwave measurements are determined using the X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The goal of this work is to compare the microwave measurements of the dielectric properties of AlN ceramic to the structural measurements. The results show that AlN has stability below 1400℃, which is the best range for microwave processing and applications of this material. AlN starts absorb more microwaves above 1400℃ due to the hydrolysis to aluminum hydroxide (Al(OH)_3).
