A simple, light-weight and efficient excavation system to excavate and collect lunar regolith has been developed at BRAC university. The excavation system has a dimension of 1.21m × 0.66m × 0.74m with a total weight of 65 kg. This four wheel drive robot consists of a bucket-ladder system for excavation and is capable of collecting 8kg of regolith per minutes. It also includes a collector bucket which can contain 18kg regolith and deposit in a bin which is installed on 50 cm height. The excavation hardware can be operated both manually and remotely through a web browser by logging in from any computer without direct visual and auditory access to the hardware. A KINECT sensor based semi-auto navigation is incorporated to avoid obstacle while motion.

Grid computing has emerged as an important field synonymous to high throughput computing. Grid computing is widely regarded as a technology of immense potential for accessing geographically distributed resources using computer networks. To ensure this new paradigm fully functional it demands several key concepts like authentication and authorization. The most commonly used security specification for grid computing is global security infrastructure or GSI. It specifies all the security aspect relating grid computing like authentication, authorization, single sign on and delegation [8]. Among all the required security features of grid computing “single sign on (SSO)” is a crucial one. But single sign on feature is missing in Alchemi .NET framework, a middleware to setup grid in windows based operating system. The architecture of Alchemi .NET framework does not possess single sign on feature which is a major security related architectural issue that exixts in current alchemi system. In this paper we have proposed a mechanism to implement “single sign on” integrating with Alchemi .NET framework. In current Alchemi .NET framework's architecture, an user connects with Alchemi grid manager directly by giving username & password via Alchemi console. In our proposal a user has to go through the single sign on mechanism to be connected with grid manager via Alchemi console to submit a grid application.

This paper proposes a structure for detecting Bangla grammar which recognizes correct Bangla sentences and rejects incorrect ones based on Head-Driven Phrase Structure Grammar(HPSG). Context-free grammars (CFG) provide a powerful mechanism for language computation but it cannot detect the semantic errors. In case of CFG, generating huge number of grammar rules for a correct sentence is very complex. Lexical Functional Grammar (LFG) have been widely used to formally specify the syntax of natural language. In this case the LFG cannot recognize the semantic correctness of a sentence. To solve these kinds of problems we have used HPSG structure for recognizing Bangla grammar. We have used the LKB system for implementing our designed Bangla Grammar. Our designed Grammar can detect the correctness of a Bangla sentences for both syntax and semantics.

Soft errors are significant concern for circuit reliability. Among various adopted techniques to mitigate soft errors effects on system functionality, Error Correcting Code (ECC) is one of the dominant approaches since it reduces cost overhead significantly. This paper deals with a new error correcting coding approach to tolerate soft errors at processor, data path, and memory devices of a computer system. To detect soft errors, the proposed approach introduces ‘modular checking’ which in turns, is working (decoding and comparing) with even and/or odd numbers of row and column of a two-dimensional array organization of pre-encoded data set rather than the whole matrix. Hence, it reduces the cost by lessen the circuitry needed to implement the scheme and the detection time is reduced as well if the soft error is detected at early modular checking. The proposed approach is able to detect soft errors at any of bit positions and correct those efficiently with reduced cost as well as detection time in a great context.

This paper presents an approach to select an appropriate location for wind power plant. Three main criteria: wind potential, transportation, and cost are considered. The purpose of this study is to present a comprehensive pairwise comparison of criteria and subcriteria for selecting the best wind power plant location. A multi-criteria decision making (MCDM) methodology-Fuzzy-Analytical Network Process (F-ANP) has been utilized to solve the problem. In fact, an analytical network structure of the criteria and subcriteria is developed according to their dependences on each other and triangular fuzzy numbers are employed for pairwise comparison among them. The extent analysis of fuzzy pairwise comparison is done to get the weight vectors. Finally from the limiting global supermatrix of weights the priorities of the locations are found. A real life numerical example is demonstrated to illustrate the methodology.

Free space optical (FSO) communication offers an attractive alternative to the radio frequency (RF) channel for the purpose of transmitting data at very high rates. Atmospheric turbulence can degrade the performance of FSO links, particularly over ranges of the order of 1 km or longer. The performance of the FSO link can be improved by employing an appropriate modulation scheme and channel model which makes a good compromise between complexity and performance. In this view, we consider in this paper the M-ary pulse position modulation (PPM) which has the interesting advantage of being average-energy efficient with gamma-gamma and negative exponential atmospheric turbulence model under turbulent condition. The performance results are evaluated in terms of symbol error probability (SEP) for different type of channel model.

In the age of electronic systems it is important to acquire and control information from everywhere. Here we present a novel secure real time method to control device. We summarizes a study conducted to examine the feasibility of implementing Global System for Mobile Communications (GSM), using Duel Tone Multi-Frequency (DTMF) as an alternative means of communication to Radio Frequency (RF) to control electrical appliances. In remote communication, DTMF signal can replace RF signal for the advantage of simplicity and audibility. A user can send DTMF tone to control home appliances or machines in industries. Any GSM mobile phone can be employed to send DTMF tone. The advantage of this system is the use of GSM technology for communication and at a time control of many devices. This paper deals with the design and experimentation, which can be useful for the people who are working in research laboratory, industry & education in the field of Communication, Control, wireless technology etc.

Electroencephalogram (EEG) is a record of electrical signal to represent the human brain activity. Many researchers are working on human brain as they are fascinated by the idea of secret, thought and feeling from the external and internal stimuli. Feature extraction, analysis, and classification of EEG signals are still challenging issues for researchers due to the variations of the brain signals. Different features are used to identify epilepsy, coma, encephalopathies, and brain death, etc. However, we have observed that extracted features from same kinds of signal transformations are not effective to differentiate the epilepsy periods including Ictal (active seizure period) and Interictal (interval between seizures) of EEG signals. In this paper we present a new approach for feature extraction using high frequency components from DCT transformation. We also combine the new feature with the bandwidth feature extracted from the empirical mode decomposition (EMD). These features are then used as an input to least squares support vector machine (LS-SVM) to classify Ictal and Interictal period of epileptic EEG signals from different brain locations. Experimental results show that the proposed method outperforms the existing state-of-the-art method for better classification of Ictal and Interictal period of epilepsy for benchmark dataset.

In this paper, a concept and investigation of orthogonal linear polarization switchable planar antenna is proposed. In order to switch the polarization axis, four switching diodes are loaded on the upper plane of the antenna. The boundary condition of the planar antenna is controlled by the ON/OFF condition of the diodes. The antenna can switch the polarization at ±45 deg. □ and 0 & 90 deg., depending on the polarity of the bias voltage and the position of the diodes. The FDTD method introduced by Yee is used to simulate the antenna which is followed by the experimental investigation.
