The static network performance and dynamic communication performance of the Hierarchical Torus Network (HTN) using dimension-order routing algorithm have already been evaluated and shown to be superior to the performance of other interconnection networks. However, the assessment of the dynamic communication performance improvement of HTN by the efficient use of both the physical link and virtual channels...
A Hierarchical Torus Network (HTN) is a 2D-torus network of multiple basic modules, in which the basic modules are 3D-torus networks that are hierarchically interconnected for higher level networks. The dynamic communication performance of the HTN using the dimension-order routing under common traffic patterns have been evaluated, and have been shown to be good. However, dynamic communication performance...
Synchronization is considered an important design issue for the implementation of digital television (DTV) receiver, specially for proper reception of multipath distorted signal at low signal to noise ratio (SNR). This challenge is more pronounced in complex multipath channel scenarios and for high mobility applications in presence of carrier frequency offset (CFO). In this paper, time domain correlation...
Ternary content-addressable memory (TCAM) has become popular in high-speed lookup intensive applications. Large dynamic power consumption of TCAMs makes power reduction techniques an active area of research. In this paper we present a new match-line (ML) sensing scheme employing ML segmentation and positive feedback in the sense amplifier of the first segment. Simulation using 130nm 1.2V CMOS logic...
For various reasons in recent years the interest in building quantum computers has increased gradually. To do the calculations in quantum computer we need quantum arithmetic logic unit (ALU). The building block of quantum ALU is quantum adder. In quantum computer multivalued logic is possible. In this paper a generalized circuit has been proposed to build odd base multivalued quantum full adder. A...
A neural representation of combinational logic circuit is proposed, called `Logical Neural Network' (LNN). LNN is a feed-forward neural network (NN) where the weights of the network indicate the connections of digital circuit. The logic operations of the circuit such as AND, OR, NOR etc are performed with the neurons of LNN. A modification of Simple Genetic Algorithm (mSGA) is applied to design and...
Single Wall Carbon Nanotubes exhibit outstanding contributions in the recent VLSI interconnections. Interconnects analyzed in VLSI circuits depends on the electrical properties of carbon nanotubes. Metallic carbon nanotubes are very distinct for their ballistic conductivity in nano level interconnections. Different peaks are analyzed in Raman spectroscopy technique for characterizing metallic carbon...
Quaternary logic requires a dedicated comparator circuit besides the usual add/sub unit which may not be optimal due to several reasons. In this paper, we have thoroughly discussed various alternative expressions for equality operator which serves as the basis for quaternary comparator. Then we have derived the necessary equations for single qudit comparator and extended it to serial multi qudit comparator...
In traditional directional spatial prediction based video coding standards such as H.264/AVC, MPEG4 and AVS, zigzag scan is the fixed scan pattern which designed to organize quantized transform coefficients in order to bring the high-frequency components as more as possible, so that the coefficients can be encoded more efficiently using the entropy encoding. However, zigzag scan cannot efficiently...
The most critical and difficult problem in speech analysis is reliable discrimination among Silence, Unvoiced and Voiced speech. Several methods have been proposed for making this three levels decision and most of them need Speech Activity Detection (SAD). In this study, we propose the Estimated Degree of Noise (EDON) to adjust the threshold of speech activity. To estimate the degree of noise, a function...
Fingerprint detection is one of the most important applications of image processing in a security system. Recent literature deals with fingerprint detection based on pattern recognition, moment based image recognition and discrete wavelet transform (DWT). Among them DWT based analysis requires the least amount of memory space which considers only wavelet coefficient of an image in matching with preserved...
Simplified visualisation of the fuel spray developing process of varied ethanol content in an open spray by the liquid injection technique. For obtaining spray characteristics in the liquid, the visualisation principles were based on spray penetrations images. The video imaging and schlieren technique have been used to investigate the spray development and behaviours at different injection time defined...
Modern signal processing applications invoke various evolutionary algorithms in different areas such as aerodynamic shape optimization, pattern recognition, digital filter design, automated mirror design etc. Presently, Differential Evolution (DE) algorithm has proved to be quite efficient in these areas. Digital filters of various kinds can be designed using this particular evolutionary technique...
In this paper auditory like features MLPC and MFCC have been used as front-end and their performance has been evaluated on Aurora-2 database for Hidden Markov Model (HMM) based noisy speech recognition. The clean data set is used for training and test set A is used to examine the performance. It has been found that almost the same recognition performance has been obtained both for MLPC and MFCC and...
Rural women in Bangladesh have limited access to resources and public spheres due to socio-cultural restrictions. Women suffer from severe discrimination, due partly to a lack of access to information. Information and communication and technologies (ICT) are tools that potentially can reach rural women and address their knowledge and information needs. Considering this scenario, the aim of this paper...
Business-to-Employees (B2E) systems represent a new breed of web-enabled eBusiness application that helps develop productive and committed workforce. However, even though eBusiness technology vendors advocate that enormous values organisations and their employees can gain from the introduction of B2E systems, no systematic empirical study is yet reported from employees' viewpoint in particular for...
Despite an increasing amount of initiatives and policy priorities remain in Bangladesh for ICT development and establishing an e-based society by 2021, lower level of internet penetration made the whole initiatives inconclusive although there are enormous potentials. This study attempts to examine individuals' intention and actual internet usage behaviour applying an extended version of technology...
IP based Wireless Sensor Networks (IP-WSN) are gaining importance for its broad range of applications in health-care, home automation, environmental monitoring, security & safety and industrial automation. In all of these applications mobility in sensor network with special attention to energy efficiency is a major issue to be addressed. Host based mobility management protocol is inherently unsuitable...
Considering the rapid expansion of the usage of mobile communication devices in Bangladesh, development of technology and reduction in cost, well designed mobile based e-learning framework is expected to contribute significantly in educational development and thereby having a long term effect on poverty alleviation. This paper shows an M-Learning framework for Bangladesh.
Many recommendations are proposed for accommodating multimedia content into wireless media with lower bandwidth. These formats of the content have been developed with different objectives. Now it has become really challenging to compare all these diversified formats. In this paper, we proposed an algorithm to compare the FLV, MPEG4 and 3GP format of multimedia content using the parameters that determines...
