Decision Tree Based Routine Generation (DRG) Algorithm: A Data Mining Advancement to Generate Academic Routine and Exam-time Tabling for Open Credit System
Ashiqur Md. Rahman,Sheik Shafaat Giasuddin,Rashedur M Rahman
Journal of Computers , 2010, DOI: 10.4304/jcp.5.1.12-22
Abstract: In this paper we propose and analyze techniques for academic routine and exam time table generation for open credit system. The contributions of this paper are multi-folds. Firstly, a technique namely Decision tree based Routine Generation (DRG) algorithm is proposed to generate an academic routine. Secondly, based on the DRG concept, Exam-time Tabling algorithm (ETA) is developed to implement conflict free exam-time schedule. In open credit course registration system any student may choose any course in any semester after completion of pre-requisite course(s). This makes the research more challenging and complex to accomplish. Academic routine and exam timetable generation are in general NP-Hard problems, i.e., no algorithm has been developed to solve it in reasonable (polynomial) amount of time. Different methods based on heuristics are developed to generate good time-table. In this research we developed heuristic based strategies that generate an efficient academic routine and exam time-table for a university that follow open credit system. OLAP representation helps to classify the courses along with the proposed algorithm to eliminate some constraints. Daybased pattern, minimum manhattan distance between courses of same teacher; minimum conflicted course distribution has been stage-managed to classify the courses. Our ETA algorithm is based on decision tree and sequential search techniques.

Acta Medica Iranica , 2011,
Abstract: We aimed to investigate the correlation of tonsillectomy with palatine tonsil size and to compare the differences of tonsil size and the need for surgery in children and adults. Also we can predict the outcome of tonsillectomy. We measured tonsil sizes in (height and width) in 150 children and 35 adults with hypertrophy of palatine tonsils and we measured the mass of tonsils and then the data analysis. In both groups of children and adults, tonsil sizes were significantly correlated with the rate of tonsillectomy. Tonsil size of grade 3 and 4 were with a high tonsillectomy rate in adults but tonsil size grade 2, 3 and 4 had a high tonsillectomy rate in children. Tonsillectomy correlated with tonsil size in both groups children and adults. The rate of tonsillectomy increased proportionally with tonsil sizes in both groups children and adults.
Strategy Formulation and Adaptation Pathways Generation for Sustainable Development of Western Floodplain of Ganges  [PDF]
Yeusuf Ahmed, Giasuddin Ahmed Choudhury, Md. Sabbir Ahmed
Journal of Water Resource and Protection (JWARP) , 2017, DOI: 10.4236/jwarp.2017.96045
Abstract: The coastal zone of Bangladesh is very heterogeneous in nature and has marvelous potential to create opportunities of national importance and contribute to GDP. Among the potentials—intensification of agriculture, aqua-culture and marine fishery, ship building industry, eco-tourism, deep sea port etc. are most significant. Unfortunately, the coastal zone of the country is disaster prone area. Poor communication, lack of education and health care facilities, prolonged absence of safe drinking water and inadequate cyclone shelters contribute and multiply the dimension of vulnerability. Furthermore, increasing population pressure increases the competition for limited resources. As a consequence, in order to unlock these potentials, existing and new interventions are required to serve in an integrated and inclusive way; calling for a distinct and integrated coastal development strategy. This study aims to investigate the issues of the western floodplain of the Ganges and propose some identical strategies and subsequent adaptation pathways to delineate the development roadmaps to decision makers and researches. Analyses have been conducted through GIS and RS technology, Dynamic Pathway Generator, Excel analysis and field investigation.

International Journal of Poultry Science , 2002,
Abstract: There was an outbreak of avian pox infection in a flock of bantams (Gallus domesticus) with gross lesions of erosions, crusts and nodules on the comb, eyelids, oral mucosa, legs and toes. In histopathological study eosinophilic intracytoplasmic inclusion bodies were visualized by light microscope in epithelial cells of the cutaneous nodules. Electron microscopy revealed numerous pox virions in the inclusion body.

S. Sheik Mohammed
International Journal of Chemical and Environmental Engineering , 2011,
Abstract: This paper presents modeling of Photovoltaic (PV) module using MATLAB/Simulink. The model is developed based on the mathematical model of the PV module. Two particular PV modules are selected for the analysis of developed model. The essential parameters required for modeling the system are taken from datasheets. I-V and P-V characteristics curves are obtained for the selected modules with the output power of 60W and 64W from simulation and compared with the curves provided by the datasheet. The results obtained from the simulation model are well matched with the datasheet information.

A SURVEY ON ENERGY EFFICIENT MODULATION AND CODING TECHNIQUES FOR WIRELESS SENSOR NETWORKS
M. Sheik Dawood
Journal of Global Research in Computer Science , 2013,
Abstract: : A standard Wireless Sensor Network comprises of a huge number of sensor nodes with data processing and communication capabilities. The sensor nodes pass the gathered data using radio transmitter, to a sink either straightforwardly or through other nodes in a multi-hop approach. Wireless sensor network is a power consuming system, since nodes perform on restricted power batteries which decreases its lifetime. Optimally selected modulation and coding is extremely vital technique in wireless sensor networks. This paper surveys the performance of differentmodulation schemes and error control codes used in sensor networks. The survey also analyzes the role of modulation and coding techniquesto improve the energy efficiency, bandwidth efficiency and lifetime of the sensor nodes. Keywords: Sensor Network, Modulation, Energy Efficiency, Coding
BIOINFORMATICS AND BIOSYNTHESIS ANALYSIS OF CELLULOSE SYNTHASE OPERON IN ZYMOMONAS MOBILIS ZM4

The IIOAB Journal , 2011,
Abstract: Biosynthesis of cellulose has been reported in many species of bacteria. The genes encoding cellulose biosynthetic enzymes of Z. mobilis have not been studied so far. Preliminary sequence analysis of the Z. mobilis ZM4 genome revealed the presence of a cellulose synthase operon comprised of Open Reading Frames (ORFs) ZMO01083 (bcsA), ZMO1084 (bcsB) and ZMO1085 (bcsC). The first gene of the operon bcsA encodes the cellulose synthase catalytic subunit BcsA. The second gene of the operon bcsB encodes the cellulose synthase subunit B (BcsB), which shows the presence of BcsB multi-domain and is inferred to bind c-di-GMP, the regulator of cellulose biosynthesis. The third gene of the operon bcsC encodes the cellulose synthase operon C domain protein (BcsC), which belongs to super family of teratrico peptide repeat (TPR) that are believed to mediate protein – protein interactions for the formation of cellulose. Multiple sequence alignment of the deduced amino acid sequences of BcsA and BcsC with other closely related homologs showed the presence of PVDPYE, HAKAGNLN, DCD motif and TPR motif, the characteristic motifs of bacterial cellulose synthases. Analysis of the nucleotide sequence of the ORF ZMO1085 and neighboring ORFs namely ZMO1083 and ZMO1084 indicated that all the ORFs are translationally linked and form an operon. Transcript analysis using Real-time PCR indicated the expression of the genes involved in cellulose synthase operon in Zymomonas mobilis ZM4. Z. mobilis colonies grown on RM-glucose containing Congo red displayed a characteristic bright red-brown colour. Z. mobilis colonies grown on RM-glucose medium supplemented with Calcoflour exhibited fluorescence. The arrangement of Calcofluor stained microfibrils can be seen in fluorescence microscopy which is an indicative for cellulose biosynthesis. AFM micrograph of the extracellular matrix of Z. mobilis shows a relatively dense matrix with bacterial cell residues. The presence of cellulose was confirmed by the Acetic-Nitric (Updegraff) Cellulose assay. The Bioinformatics and biosynthetic analysis confirm the biosynthesis of cellulose in Z. mobilis.

Tekhnologiya i Konstruirovanie v Elektronnoi Apparature , 2012,
Abstract: The special features of the synchronization of data flows in the multichannel DSP systems with different architecture are examined. It is shown that in a number of cases the timing system can be realized in the form of a totality of local systems, which makes it possible to lower the level of the interferences created by them and to simplify their realization due to the reduction of the number of global connections. The method of the integrated assessment of the realization efficiency (equipment expenditures) of the projected system taking into account the complexity of timing system is proposed.
