A flexible planar textile antenna suitable for wearable applications has been designed at 2.4GHz. The effects of the dielectric substrates of the micro strip antenna have been investigated. Such materials are: fleece, denim and Velcro. Both edge mounted and vertical mounted excitation configurations are considered. It is observed that for edge mount, micro strip line feeding, antenna with fleece provides highest gain (7.59dBi). However the impedance bandwidth with the same feeding is higher for the antennas with denim substrate (25%). Moreover the impedance bandwidth can be enhanced (36%) by using vertical feed. The numerical study has been performed using CST microwave studio. © 2016 IEEE.

A quantitative study has been performed in order to investigate the effects of human body on antenna performance. The analysis has been carried out at 900, 1800 and 2400 MHz using a half-wave dipole antenna. The antenna is positioned perpendicularly to the body. At each frequency, the antenna has been moved towards the human body from a distance of onewavelength to zero. A mathematical equation has been proposed relating the antenna gain with the distance from the body. A reasonable match has been obtained between the simulated and calculated gain. For simplification, a flat slab of muscle has been used to represent the human torso. Results show that, the gain of antennas varies exponentially from one-fourth of a wavelength to one-wavelength. Coefficients of the equations at the concerned frequencies are also presented. CST microwave studio and MATLAB are used for the numerical analysis. © 2016 IEEE.

Environmental concern is at the center of green banking practices. The public concern of the state of the environment has been growing rapidly in the last few years mostly due to apparently unusual weather patterns, rising greenhouse gases, declining air quality, declining non-renewable energy resources, etc. In particular, cities like Dhaka are severely affected with the changing environment and unsustainable energy situation. Banks hold a unique position in an economic system that can affect production, business, and other economic activities through their financing activities. Alongside handling environmental risks, banks may contribute by saving energy resources in their own operations and may also influence their clients to save energy resources. In Bangladesh, a lot is to be done to attain the expected level of environmental standard; however, remarkable development has taken place in terms of green banking practices. The broad objective of the conference paper is to evaluate the relevance of green banking practices for attaining energy sustainability in Dhaka city. The study observes that banks can play critical roles in attaining energy sustainability in Dhaka city through green activities. © 2013 WIT Press.

The internet has increased the copy-paste scenarios amongst students as well as amongst researchers leading to different levels of plagiarized documents. For this reason, much of research is focused on for detecting plagiarism automatically. In this paper, an initiative is discussed where Natural Language Processing (NLP) techniques, as well as supervised machine learning algorithms have been combined to detect plagiarized texts. Here, the major emphasis is on to construct a framework which detects external plagiarism from monolingual texts successfully. For successfully detecting the plagiarism, n-gram frequency comparison approach has been implemented to construct the model framework. The framework is based on 120 characteristics which have been extracted during pre-processing the documents using NLP approach. Afterwards, filter metrics has been applied to select most relevant characteristics and then supervised classification learning algorithm has been used to classify the documents in four levels of plagiarism. Confusion matrix was built to estimate the false positives and false negatives. Our plagiarism framework achieved a very high accuracy score of 89% with low false positive and false negative rate. © 2016 ACM.

This study tested the reliability, validity and factor structure of the Bangla translated Mindful Attention Awareness Scale (MAAS). Three scales – the Bangla MAAS, the short form of health 36 (SF-36) and the Internet Addiction Test (IAT) – were applied to 519 university students (51.4% female). Ninety-two participants were retested over a two weeks period to examine test-retest reliability. Consistent with previous studies, the results of exploratory and confirmatory factor analyses showed a single factor solution for the Bangla MAAS (χ2/df = 222.243/90 = 2.47, CFI = 0.93, NFI = 0.87, and RMSEA = 0.053). The temporal stability and internal consistency was also satisfactory (Cronbach's alpha 0.85). The Bangla MAAS was significantly and positively associated with SF-36 Mental and Physical health components and negatively with IAT scores. Additionally, MAAS scored significantly varied with the presence of physical illness and different living conditions, suggesting the validity of the tool. The Bangla version of the MAAS is, therefore, a valid and reliable tool to measure mindfulness among young Bangladeshi adults. © 2016 Elsevier B.V.

Human posture identification for motion controlling applications is becoming more of a challenge. We present a posture classification system using skeletal-tracking feature of Microsoft Kinect sensor. Posture recovery is carried out by detecting the human body joints, its position, and orientation at the same time. Angular representation of the skeleton data makes the system very robust and avoids problems related to human body occlusions and motion ambiguities. The implemented system is tested on a class of relatively common postures comprising hundreds of human pose instances by different people, where our classifier shows an average accuracy of 94.9%, 96.7% and 96.9% for linear, exponential and priority based matching systems respectively. © 2012 IEEE.

This paper presents a hybrid task allocation strategy for decentralized groups of mobile agents. The work is strongly inspired by the biological behavior of social insects. Agent based modeling approach has been used to model the behavior of agents. Environment of the model comprises of set of tasks and heterogeneous groups of mobile agents. Each group of agents follows respective local rules to communicate with neighboring agents and with the environment in their vicinity. The agents can not only carry out their own tasks but can also switch tasks to meet colonial demands. This paper presents an extension of a series of models presented earlier. In earlier models, agents reacted only to stimulus. Although evidence exists of task preferences among castes (bias) in many ant species, little work has been done in investigating the benefits for the colony of such preferences. This paper addresses the role of bias in the colony performance under different environmental circumstances. Experiment results indicate that the model presented in this paper is highly efficient, accurate and consistent with biological equivalents. The model with bias within a group is novel and has not been done before to the best of my knowledge. © 2013 The Authors. Published by Elsevier B.V.

Bangladesh is a developing country. In developing countries, there is a digital divide between rural and urban areas. We need to provide locally relevant ICT services to overcome these divisions. Traditional software development methods are not suitable for developing the software of rural areas because they cannot serve the unique needs and complexities of such areas. I have tried to find the most appropriate way to engineer suitable software applications for rural communities of Bangladesh. I have developed a methodological framework for creating software applications for rural community. Socially structured computing framework to create software applications using the principle of action research and participative Design Guide as the best practices that helped me address all the problems that affect the success of the application. On the validity of the framework, I show that by using it to create Telemedicine Communicator (TC). TC is a prototype system for remote consultations in health for rural communities. It allows for communication between a small hospital in a village and a bigger hospital in neighboring village. It uses Voice over Internet Protocol (VoIP) combined with a store and forward approach to communications. TC can be tested over a Wireless Fidelity (wireless) network as well. Within social consciousness, it is suitable for the local development of relevant applications for rural areas of Bangladesh. I found that TC is an improvement of the solution of telemedicine in the community of destiny. Using this approach also led to a lot of knowledge about best practices for ICT development projects. I am also proposing that VoIP and Wi-Fi technology is relevant to rural areas and that the liberalization of telecommunications in Bangladesh is still needed to promote technological development in rural and underserviced areas. © 2005-2010 JATIT.

Traditional median filters perform well in restoring the images corrupted by low density impulse noise, but fail to restore highly corrupted images. Conversely, the advanced adaptive median filters are capable of denoising high density impulse noise but the image details are compromised significantly. In this paper, a new adaptive fuzzy median filter is presented to provide optimum detail preservation along with very high density noise removal. The novelty of this research work comes from two directions. Firstly, we used a triangular fuzzy membership function to determine the level of corruption at each pixel that consequently ensures the replacement of noisy pixels according to the extent of corruption. Secondly, we exploited fully adaptive and automatically adjustable threshold value to provide ease of computation. Experimental results show that the proposed filter outperforms other conventional and advanced filters in terms of both denoising and fine detail preservation of highly corrupted images. © 2013 IEEE.
