Economic-based resource management models are found to be efficient for distributed resource collaboration in the Grid. Due to the wide range of applications and dynamic nature of Grid resources, constant performance by a specific economic model is therefore subjective. This work identifies the potential of different models in different scenarios in the Grid. This identification motivates us to design...
A Midimew connected Mesh Network (MMN) is a MInimal DIstance MEsh with Wrap-around links network of multiple basic modules, in which the basic modules are 2D-mesh networks that are hierarchically interconnected for higher-level networks. In this paper, we present the architecture of the MMN, addressing of node, routing of message, and evaluate the static network performance of MMN, TESH, mesh, and...
Poster that represents a video has many applications in internet and media world. In this paper, a method is proposed to generate poster based on color feature and relevance feedback. Color feature is used because it is more closely to human perception and it is easy to extract, match and also effective for indexing. In our method as color feature of a frame in a video, HSV color space and Color Moment...
In this paper we propose a neural net based characters recognition scheme for Bangla printed text books. There are a lot of scientific literature, novels, magazines and books etc that are written in Bangla language. More than 400 million people use Bangla language. Most of the library and educational institutions want to keep copy of the books in a digital format. For storing those books in digital...
The requirement of Bangla character recognition has become one of the prime attentions among the current researchers due to the increase of automated systems and usage of hand held devices. This paper presents a novel approach to recognize handwritten bangla numerals and addresses a robust feature extraction scheme that spawns 23- dimensional features based on the numeral's structure and topology...
Optimizing the three most important network performance parameters i.e. Delivery probability, Overhead ratio, and Delay is challenging in Delay Tolerant Networks (DTN) due to high occurrences of network partitioning in these networks. Owing to the partitioning nature efficient routing or dissemination of messages is important in DTN. In this paper, we focused to improve the spray phase of Binary Spray...
Wireless sensor network is one of the most promising technology in wireless network. To design a sensor network, improving the lifetime of sensor node is critical issue. For these reason researchers in these field pay great attention to Medium Access Control (MAC) protocol. As most of the nodes are placed in remote and hazardous area, so when the power is down it is difficult to recharge them or it...
Fault tolerance is the ability to a system to continue its functionality despite the presence of faults in the architecture. For a dynamic system such as the cloud, fault tolerance is required to ensure business continuity. This paper proposes a high availability middleware that ensures fault tolerance for cloud based applications. Effective Descriptive Set Theory is used to determine the model of...
Asthma is a common chronic inflammatory disease. A belief rule based Clinical Decision Support System (CDSS) of asthma suspicion is enhancing the accuracy of suspicion. This research paper presents out the development of a Belief rule based (BRB) system to assess Asthma suspicion by using signs and symptoms. The recently developed generic belief rule-based inference methodology by using the evidential...
Electroencephalogram (EEG) signal plays an important role in the field of brain-computer interface (BCI) which has diverse applications ranging from medicine to entertainment. BCI acquires brain signals, extracts informative features and translates these features into a control signal for an external device. The Purpose of this work is to select proper frequency band and to extract suitable features...
Cardiovascular diseases such as; heart attack (coronary thrombosis, myocardial infarction), hypertension, stroke, coronary artery disease (CAD), congestive heart failure, peripheral artery disease (PAD) and diabetes create a new concern worldwide due to its harmness. In Bangladesh where majority live in rural areas that lack specialist care, we envision the need for much larger Internet-based telemedicine...
The Resource-Constrained Project Scheduling Problem (RCPSP) is a classical well-known and NP-hard problem which includes the resource and precedence constraints that has been applied to many applications. This paper proposes the Radius Particle Swarm Optimization (RPSO) to solve the RCPSP. It extends the Particle Swarm Optimization (PSO) by regrouping the agent particles within the appropriate radius...
In recent years, investigating national incidents of Bangladesh it has been seen that social network played a vital role. Though social network sites like Facebook, Twitter, and Google+ are mainly used for connecting people all over the world but they are now being used for advertisements, news updates and for various important purposes of day to day happenings. Microblogging is getting more and more...
In this paper, performance of a novel analytic model of direct sequence code division multiple accesses (DS-CDMA) using diversity with maximal ratio combining (MRC) scheme is observed under the influence of multipath Rayleigh fading and multi-access interference (MAI) varying different system parameters and properties of PN sequences. The analysis presents a mathematical expression for bit error rate...
Development of text entry speed and accuracy is the key concern for designing and evaluating a soft keyboard. Bangla language has large collection of characters and it is hard to design a single layered fixed layout keyboard to provide highperformance in today's small mobile device. The traditional soft keyboards available in the market are multi-layered and menu based hierarchical keyboard which...
This work is based on developing a system for the Bell's palsy, a type of facial nerve paralysis, patients to help them in passive exercise, which is one of the major ways to recovery. This exercise method will be provided in the form of computer game so the user will be able to perform exercise without the hardship that comes with active exercise. It will also show how much this system helps the...
Several researchers have successfully developed realistic technique for specialized voice service in networked virtual enthronement (NVE) like Second Life. Specialized voice service in virtual environment enables users to speak to each other naturally and seamlessly. The spatial 3D avatar location and the voice direction in the virtual environment are used to generate realistic sound. Although with...
This paper presents the design and analytical studies of a novel dual-band microstrip patch antenna operating at two frequencies of ISM bands: 2.45 GHz and 2.84 GHz. The necessity for multiband antennas is increasing with the demand of wireless communications and as a result, light-weight, low-volume and low-profile microstrip patch antennas have been nourished by the researchers which initiated our...
The protein inference problem represents a major challenge in proteomics research. In this paper, we propose a novel meta-heuristic approach i.e. PIssGA to infer proteins from a given peptide sequence identified from tandem mass spectrometry in shotgun proteomics. Although most of the works available in the literature mainly adopts parsimonious pressure i.e. prefer least number of inferred proteins,...
