Education is recognized as one of the most powerful aspects for human development. Scope of education includes dispersal of knowledge, logical thinking, flourishing skills, refining habits, and sharing values. Accordingly, basic or primary education is a fundamental right for every citizen of a country. Studies provide sufficient evidence that individuals lacking primary education are incapable of...
Using Social Network Sites (SNS) as an information source has drawn the attention of the researchers for a while now. There has been many works that analyzed the types and topics of questions people ask in these networks and why. Topics like what motivate people to answer such queries, how to integrate the traditional search engines and SNS together are also well investigated. In this paper, we focus...
The Microsoft Kinect sensor has brought a new era of Natural User Interface (NUI) based gaming and the associated SDK has provided access to its powerful sensors, which can be utilized in many ways, especially in research purposes. We have already seen its use in robotics, developing assistive technologies, and augmented reality, aside from gaming. Thousands of people around the world are playing...

This research addresses the issues affecting e-Governance implementation in Bangladesh in consideration with a detailed usability analysis and directions for future development. Implementing e-Governance has always been a challenge either it is social, economical, or political. Besides this, there are many technological problems, which should be understood and met, so that a user-accepted e-Governance...
Location Based Advertisement (LBA) has become today's most personal and direct marketing channel that provides customers more relevant information, personalized message, targeted offer about products and allows marketers to reach a specific target audience by creating campaigns. Location-based advertising (LBA) is a new form of advertising that integrates mobile advertising with location based services...
This research addresses the issues affecting e-Governance implementation in developing countries in consideration with implementation of the 3G mobile networks. Implementing e-Governance has always been a challenge either it is social, economical, or political. Besides this, there are many technological problems, which should be understood and met so that a user-accepted e-Governance system emerges...
The distributed coordination function (DCF) of the IEEE 802.11 standard based medium access control has drawn significant interest from the researchers in the past decade. Many proposals of its performance analysis and modifications to remove its limitations are proposed. In this paper we are considering some recent proposals to make a detailed study of the performance comparison between DCF, CONTI,...
Faced with an increasingly difficult challenge in growing both the average revenue per user (ARPU) and the number of subscribers, wireless carriers and their partners are developing a lot of new products, services, and business models based on data services. Location based services, which provide information specific to a geographic location, are a key part of this portfolio. Our Location Based Information...
Ensuring a computer based quick and accurate patient management system has been a challenging goal for many years. And it adds additional challenges in undeveloped countries where the doctor-patient ration is quite higher than in the developed ones. In our research, we identified the user requirements and then addressed the issues from a software engineering perspective to find an easy, yet efficient...
Standards groups and regulatory bodies around the world are increasingly seeking new ways of using and allowing access to allocating spectrum. In most parts of the world, cellular network bands are overloaded, but amateur radio and paging frequencies are not. Independent studies performed in some countries confirmed that observation, and concluded that spectrum utilization depends strongly on time...
With the ever-increasing popularity of cell phone devices, text based services on such devices are becoming more and more popular. Problems with traditional keypads primarily lie with the placement of the letters alphabetically on the keys. This configuration is comparatively easy for the users to remember but can greatly limit the flexibility of finger movement, as well as require a higher number...
OpenStreetMap (OSM) is a world-wide campaign for developing open source maps. With the ever increase in the rate of cell phone usage, the necessity of location based services is increasing day by day and the prospect of such open source maps is very bright in commercial, educational and political points of views. Starting from the 3G mobile applications to cheap SMS-based services, we need maps everywhere...
The emergence of vehicular ad-hoc network (VANET) has provided the vital answer to vehicular communications. VANET can be either infrastructure based or simply lacking any. In our paper, we have dealt with an exemplary network that requires the presence of no such agent. VANET acts in a way applying any of the three methods: it either exchanges information between vehicle to vehicle, vehicles to roadside...
Autism is a general term used to describe a group of complex developmental brain disorders known as Pervasive Developmental Disorders (PDD). It is a life-long disability that prevents people from understanding what they see, hear, and sense. This results in severe problems with social relationships, communications, and behavior. Autism is typically diagnosed between the ages of two and six, although...
Microcredit was introduced in Bangladesh in the early '70s and since then, it has been considered as one of the principal means of socio-economic development in many parts of rural Bangladesh. However, the impacts of Microcredit are often criticized and the ultimate objectives are sometimes accused to be missing in reality. We conducted a field study at the district of Jamalganj in Sylhet, Bangladesh...
Multiuser dynamic OFDMA based IEEE 802.11 distributed coordination function (DCF) has received significant interest from the researchers in recent time. Though several proposals have been made, to the best of our knowledge, none of these have presented an analytical model for this kind of medium access control protocols for IEEE 802.11. This paper provides a simple, nevertheless, very accurate analytical...
In this paper, we discuss the problems associated with the present contention resolution mechanism of IEEE 802.11 DCF and present a new, dynamic and robust approach to improve it. Our new MAC, using OFDMA in the physical layer, can incorporate multiple concurrent transmissions or receptions in a dynamic manner and can adjust the collision probability based on the traffic load when nodes are endowed...
