This paper deals with the alignment of multiple homologous gene lists, which is a specific problem of multiple sequence alignment. In this case, the smallest unit of the input sequences is comprised of complete genes. An efficient graph based algorithm for the alignment of multiple homologous gene lists is presented in this paper. The fundamental concept to multiple sequence alignment and the graphical structure of the genomic segments are provided. Two heuristics are developed for the resolution of local alignment conflicts which reduces the search space while searching for the candidate link for deletion. The performance of the proposed algorithm is assessed by comparing the alignment results of homologous genomic segments in Arabidopsis thaliana to those obtained by using other alignment methods.

We consider an underlay cognitive radio network consisting of a single pair of primary transmitter-receiver PTx-PRx and a group of M secondary transmitter-receiver pairs STx-SRx within the transmission range of the primary system. Secondary transmitters are partitioned into two groups K, KεM active secondary transmitters STi, i ε {1, 2,…, K} which may transmit data with the co-existence of PTx below a certain interference threshold to the primary receiver and (M-K) inactive secondary transmitters STj, jε {1, 2,…, (M-K)} which are in idle state, ready to assist the primary system when the data rate between PTx and PRx over a direct link falls below the target rate Rtarget. In this paper, we propose a cooperative relay selection scheme where one of the inactive STj which achieves the primary target Rtarget will be selected as a best relay to forward the primary information. Simulation results show the effectiveness of our proposed system.

E-business modelling is already an established term as it converts technology into economic value. Sustainability is another global contemporary issue. While modelling e-business for sustainability it is essential to know the ‘blended value process’ of the proposed value based on which ‘business process’ is derived. The ability to incorporate between the blended value process and the business process is one of the imperative factors that play very significant roles for the companies to be competitive in today's exigent market. A number of research works exist on sustainability, e-business modelling, and value creation but none of them clearly explains the importance of incorporation between these two processes or how business process can be obtained from value process in e-business modelling. We, therefore, demonstrate in this article the process of how business process can be derived from blended value process in sustainable e-business modelling using process algebra. We also provide an illustrative example of our approach for enhanced understanding.

Myopathy, one of the most frequent inherited musculoskeletal diseases resulting in muscular weakness. Muscle cramps, tautness & spasm are also associated with myopathy. The electromyography (EMG) signals are biomedical signals that examine the muscle function through the inquiry of the electrical signal the muscles emanate. As the nervous system controls the muscle activity, the EMG signals can be viewed and analyzed in order to recognize the indispensable features of myopathy disease in individuals. The aim of this work is to dissociate the myopathic signals by studying the time & frequency domain features of the EMG signals. In this paper, autocorrelation (ACR), zero crossing rate (ZCR) as time domain features, mean frequency as frequency domain feature and Short Time Fourier Transform (STFT) as Time-frequency feature; are extensively analyzed on EMG signals of both the normal persons and the patients to successfully distinguish the patients from normal group. In order to comprehend this aim, EMG signal database was obtained from a normal control group consisted of 6 healthy persons & a group of patients with myopathy consisted of 6 patients. The analytical results show that myopathic signals have lower autocorrelation peak then the healthy ones and zero crossing rate and mean frequency of the affected signals are higher than the normal persons. In addition to that the power level of the spectrogram of the myopathy patients is considerably lower than that of the normal group and frequency shifting to higher frequency region for peak values.

Wireless communication system incorporating coherent OFDM requires the estimation and tracking of the channel Impulse Response (CIR) for accurate demodulation of data at the receiver. In pilot-symbol-aided OFDM system, Minimum Mean Square Error (MMSE) estimator performs better than Least Square (LS) estimator; however, computational complexity associated with the MMSE method is relatively higher than the LS. Although, the LS estimator has lower complexity and requires minimum knowledge the channel state information, the estimator suffers from inherent additive Gaussian noise and Inter Carrier Interference (ICI). Following that, in this study an efficient and improved channel estimation technique is proposed based on the LS algorithm. Simulation results show that the proposed method performs considerably better than the conventional LS method for a range of Signal to Noise Ratios (SNRs). In addition, the performance of the proposed method is found to be almost equal, if compared with the MMSE estimator. Despite the proposed method experiences relatively higher computational complexity than the LS, the complexity is yet to be achieved about 40 % lower than the MMSE.

Wireless Sensor Devices are becoming more attractive as a sensor platform compared to wired sensor device because of the ease of installation and freedom in sensor placement. The field of Wireless Sensor Network (WSN) has been increasing with the advancement of modern science and technology. In order to determine the location of sensor nodes, lots of localization algorithm have been established and proposed by the researchers. Since the Received Signal Strength Indicator (RSSI) is assumed to be a strong parameter, most of researches have been worked out for localization algorithm using RSSI. But it is found that lots of irregular values of RSSI are produced at different conditions. Thus it is so much troublesome to get the actual position of sensor nodes using RSSI. In our experiments, we tried to investigate the reasons of deviation in RSSI values in different conditions using TelosB sensor nodes. We showed the effects of different obstacles between the sensor nodes and their different orientations as well. The results show that, the distances, obstacles and sensor node orientations play a significant role in changing the RSSI values.
与有线传感器设备相比，无线传感器设备作为传感器平台正变得越来越有吸引力，因为它易于安装和自由放置传感器。随着现代科学技术的进步，无线传感器网络(WSN)领域不断发展壮大。为了确定传感器节点的位置，研究者们建立并提出了许多定位算法。由于接收信号强度指标(Received Signal Strength Indicator, RSSI)被假设为一个强参数，所以大多数研究都是基于RSSI的定位算法。但是我们发现在不同的条件下会产生很多不规则的RSSI值。因此，使用RSSI来获取传感器节点的实际位置是非常麻烦的。在我们的实验中，我们试图利用TelosB传感器节点来研究不同条件下RSSI值偏差的原因。我们还展示了传感器节点之间不同障碍物及其不同方向的影响。结果表明，距离、障碍物和传感器节点方向对RSSI值的变化有显著影响。

In this paper, we present a new and efficient algorithm for solving the longest common subsequence problem between two run-length-encoded (RLE) strings. Suppose Ŷ and X are two RLE strings having length k and ℓ, respectively. Also, assume that Y and X are the two uncompressed versions of the two RLE strings Ŷ and X having length k and ℓ respectively. Then, our algorithm runs in O((k + ℓ)+R loglog(kℓ) + R log log ω) time, where ω = k + ℓ and R is the total number of ordered pairs of positions at which the two RLE strings match. Our algorithm outperforms the best algorithms for the same problem in the literature.

Accessibility of computer for visually impaired people is a Challenging task. This paper presents software named Mongol Dip, which provides audio-based interactive interfaces to help people with visual impairments to explore and navigate windows operating system. In this software we have used text to speech technology (TTS) to echo every operation done by the user. Mongol Dip provides the easiest interface that helps the visually impaired people to access computer. Visually impaired people cannot read out Bangla text document via computer because existing software they use to operate computer do not support Bangla text. Bi-lingual (English & Bangla Language) support is the main significant part of our software. Hence the main goal of this software is to assist the people with visual impairments to operate computers and connecting with the digital world using minimum operations and maximum usability using bi-lingual TTS support.

Attracting people attention to initiate an interaction is one of the most fundamental social capabilities both for the human and the robot. If the robot would like to communicate a particular person, it should turn its gaze to that person and make eye contact with him/her. However, only such a turning action is not enough to set up an eye contact phenomenon in all cases specially, when the robot and the target person are in greater distance and they are not facing each other. Therefore, the robot should perform some actions so that it can attract the target person before meeting his/her gaze. In this paper, we propose three actions (head turning, head shaking, and reference terms) for the robot as its attention attraction capabilities corresponding to the three viewing situations (near peripheral field of view, far peripheral field of view, and out of field of view) of human. A preliminary experiment using twelve participants confirms the effectiveness of the robot actions to attract human attention.
