The Perna sp. Perna indica is an important marine bivalve resource due to their dietary and medicinal properties. The increasing atmospheric CO2, ocean warming and consequent acidic changes of the ocean waters adversely affected these sedentary organisms by directly influencing the physiological activities and their energy levels. Experiments were conducted in the present study to infer the influence of temperature on the physiological responses of Perna sp. collected off Kadiapattanam coast, Tamil Nadu, India. The mussels were acclimatized at different temperatures viz., 25.0 to 40.0°C and the oxygen consumption levels were examined. The results indicated that the smaller size group P. species. (viz., 60 mm shell length) was more active at 35.0°C compared to the larger size groups. The oxygen consumption of P. indica acclimated at 35.0°C was higher with 0.0.37±0.01ml/lit/g/h than those acclimated at 40.0 and 25.0°C. It was also observed that, byssal threads were not produced by those specimens reared at the temperature of 25 to 40.0°C at 60 to 80mm shell size species at 1hour interval. The observations point out to the fact that temperature increase due to global warming and size variation could adversely affect physiological responses of the Perna sp. in its natural marine conditions.

During the current years, eBanking has been adopted quite extensively as a channel of distribution for financial services, and this is mainly due to speedy progress in ICTs and competitive banking markets. iBanking permits extended customer contact through vast geographical reach at lower cost of delivery channels. Another vital benefit of eBanking is the collection and management of useful information. Internet has proved as an efficient channel for the banks to gather information from customers and manage them in a best way to meet the wide range of financial needs of individuals and businesses. Currently the customers in the developed countries like UK, USA, Sweden, and Denmark are enjoying the benefits of eBanking but Pakistan is still lagging far-behind in the field of eBanking. This research is focused to study the prospects of eBanking in the city of Dera Ismail Khan, KPK, Pakistan. The researcher has reviewed the literature from different countries of the World, and developed and tested a research model in the local environment.

The present paper is focused on the modification of the properties of polystyrene by adding cobalt chloride and manganese chloride. The composites are prepared using casting technique with different percentages of fillers. The experimental results show that the D.C conductivity of composites increases with the increase of cobalt chloride and manganese chloride concentrations. The D.C electrical conductivity changes with increasing of temperature. Also the activation energy of electrical conductivity of (PS-CoCl2) and (PS-MnCl2) composites decreases with increasing cobalt chloride and manganese chloride concentrations.

One of the issues in perception research that continues to be a matter of intrigue and moot point for both philosophy of perception and its neurophysiology is how vision can play an active role in the haptic adeptness of the visually deprived, especially the congenitally blind and the early blind, if it is granted that visual and tactile modalities follow two different routes of processing of information in the brain. Traditionally, philosophers adhering to the empiricist tradition, such as Berkeley and Locke have maintained that although visual and tactual modalities share one thing in common in that they can process the same object property like figure, spatial properties like distance and motion, the mode of visually grasping any of these properties is at variance with that of haptically perceiving them. This view offers one alternative to a locus classicus in this field of study — the oft-cited Molyneux’s dilemma over whether a long-time blind person familiar with object shapes through touch would also be able to identify the shape for the first time if he ever recovers his visual sensory capacity. In this brief study evidence has been collated, examined and analyzed in support of another alternative to Molyneux’s question. In this alternative, a case has been made for a robust visuo-tactile interplay. Another question this study addresses is whether the skillfulness perceived in vision-mediated tactile performance sparked by loss of vision or forced visual deprivation is an outcome of compensatory but de novo neural restructuring or indicates an integral, latent capacity for neuroplasticity that harnesses visual or spatial imagery so as to help the visually deprived sail through tactile identification and discrimination activities.

AbstractIn this work, a neural network with chaos activation function has been applied as a pseudo-random number generator (PRNG). Chaotic neural network (CNN) is used because of its noise like behaviour which is important for cryptanalyst to know about the hidden information as it is hard to predict. A suitable adaptive architecture was adopted to generate a binary number and the result was tested for randomness using National Institute of Standard Technology (NIST) randomness tests. Although the applications of CNN in cryptography have less effective than traditional implementations, this is because these systems need large numbers of digital logic or even a computer system. This work will focus on applications that can use the proposed system in an efficient way that minimize the system complexity.

Sensor networks have been widely employed in many real-time applications. One of the most obvious challenges appearing to threaten the successful deployment of sensor networks is privacy issues including source-location privacy which can not be adequately addressed by general security mechanisms. Focusing on this important kind of privacy, among many approaches proposed in literatures, self-adjusting phantom routing is a very successful one. But it still has some weaknesses. In this paper, we propose an improved version of it to enhance its performance. This method can decrease energy consumption and communication cost while increase the accuracy of the aggregate locations by minimizing their monitored areas.

This study aims to: observe overall faculty stress level; detect weights of different factors of job satisfaction; discern overall faculty job satisfaction level; and examine relationship between occupational stress and job satisfaction. Two questionnaires are adapted in order to accomplish the research objects through acquiring the responses from faculty members of HEC recognized public and private universities in the province of Punjab. Descriptive statistics, frequency tables, arithmetic means, standard deviation, and correlation analysis are used to analyse the data. Results indicate that most of the teachers do not perceive occupational stress as a big problem in university environment. They perceive administrative factors as highly contributing factor in job satisfaction. In last, insignificant relationship is found between occupational stress and job satisfaction. The research makes a fruitful contribution in the existing body of knowledge by reporting the phenomena of stress and satisfaction in faculty of universities of Pakistan.

The problem of robot selection plays an important key role concern to various fields of different applications since three decades. This problem has become more difficult in recent years due to increasing complexity of applications of the environment, features and specifications, and facilities offered by various manufactures. The primary objective of this paper is to select the suitable type of robot based on various factors such as type of application, payload, working environment, accuracy, lifespan, weight, purchasing cost etc. The selection procedure is developed for selection of particular type of robot based evaluating the various alternative selection factors using AHP technique and systems of equations of the matrices i.e. Eigen values and Eigen vectors. The ranking evolution will provide a good guidance for the robot selection to the end user. The concept of this work is an attempt has been made to create exhaustive database for identifying maximum possible number of attributes.

In present day to day life, effective data hiding methods are needed due to attack made on data communication. This paper presents the technique for the above requirement. In this proposed method, secret message in form of audio file is embedded within another carrier audio file(.wav). In the transmitter end the output will be similar to the carrier with secret message embedded inside. The hacker will be blinded by the transmitted signal. At the receiver end the original message can be retrieved without any loss. The entire proposed system is simulated and their corresponding waveforms prove the effectiveness of this method.

The purpose of this study was to investigate the influence of intelligent classroom and deepen student's learning speed. This analytical method and the method of data collection tools and library resources, articles and scientific sites are used. The results showed that the use of multimedia content in a wide range of senses of the students involved in the teaching and learning process is deepening. In other words, in addition to increasing the performance of various classes of applications due to the use of audio-visual senses to help students learn. The system allows students to move beyond their curricula and more emphasis on thinking skills and deep learning students. The intelligent interaction between students and teachers of the school, more intelligent, and this can lead to a higher share successful experiences between them. So schools by creating platforms for intelligent classes can take advantage of this training method used.
