  Speech recognition and speaker identification are important for authentication and verification in security purpose, but they are difficult to achieve. Speaker identification methods can be divided into text-independent and text-dependent. This study presents a technique of text-dependent speaker identification using MFCC-domain Support Vector Machine (SVM). In this research, Mel-Frequency Cepstrum Coefficients (MFCCs) and their statistical distribution properties are used as features, which will be inputs to the neural network. This research firstly used Sequential Minimum Optimization (SMO) learning technique for SVM that improve performance over traditional techniques Chunking, Osuna. The cepstrum coefficients representing the speaker characteristics of a speech segment are computed by nonlinear filter bank analysis and discrete cosine transform. The speaker identification ability and convergence speed of the SVMs are investigated for different combinations of features. Extensive experimental results on several samples show the effectiveness of the proposed approach.

  M-commerce is one of the most important application domains for mobile devices, enabling users to perform commercial transaction at anytime and wherever they go. As a low cost wireless communication system we could use m-commerce for socio-economic development of Bangladesh. In this study, we proposed two m-commerce models for the development of m-commerce in Bangladesh, especially for the payment of electric bill, gas bill and water bill in an easy way. With the existing availability of the mobile phones and present socio-economic condition, our technique may be implemented for the payment in urban area and most of the rural area.

  Carps are being cultured in Rajshahi District in several forms like, in nursery pond, in rearing pond, in grow-out pond and recently in Beels. A research was designed on the polycutlure of both native and exotic major carps concerning the total cost involved and total return obtained with an objective to find out the profit status of carp culture in Rajshahi region. In this study, a clear relation is found between the total investment cost and total return. Maximum cost was found to be involved in nursery pond and minimum cost in Beel Mail as 223,052.00 and 3417.00 taka ha 1, respectively. Similarly, total return was also come from nursery pond culture system and minimum return from Beel Mail as 475,500.00 and 4030.00 taka ha 1, respectively. But the rate of profit in contrast of investment was found maximum in case of grow-out pond and minimum in Beel Mail as, 154 and 17%, respectively. However, the profit percentage of different pond culture system is more or less similar but significantly different from in Beel culture system.
