Study of SMS security as part of an electronic voting system

This thesis report is submitted in partial fulfillment of the requirements for the degree of Bachelor of Science in Computer Science and Engineering, 2006.Cataloged from PDF version of thesis report.Includes bibliographical references (page 48).E-voting is a new technology in voting system. Recently it was experimented in UK. Basically, this system is proposed to work via Short Message System (SMS). Using secure messaging system we are trying to develop the e-voting system here in our country. Our goal is to develop a system, which will be able to send SMS from a registered cell phone to a server located in the base polling station and cast a vote for a voter. The system must be secured so that while voting, no outside interference can be made to change the vote. So, there will be no tension of casting false vote. By the help of this system our voters will be able to cast their votes in a secure way and also the results will be available immediately when the vote casting finishes. This is going to be a pioneer change in our voting system. Some work on this proposed system has already been done. We wish to carry out the proposed system into further details. That is security aspects and implementation.B. Computer Science and Engineerin

Certain unrest in the Textile Industry in Bangladesh; 6. Some emerging issues in the textile industry in Bangladesh; 7. Competition between Bangladesh and Other Exporting Countries; 8. Assess the Domestic supply for the production; 9. Different setbacks faced in production; 10. Textile Quota removal by WTO, its impact on Bangladesh. The research aims shows that what are the flaws that could be cured to provide better scopes, which would help the industry to grow more widely, and help in the welfare of the country’s economy

LMFLOSS: A Hybrid Loss For Imbalanced Medical Image Classification

Automatic medical image classification is a very important field where the use of AI has the potential to have a real social impact. However, there are still many challenges that act as obstacles to making practically effective solutions. One of those is the fact that most of the medical imaging datasets have a class imbalance problem. This leads to the fact that existing AI techniques, particularly neural network-based deep-learning methodologies, often perform poorly in such scenarios. Thus this makes this area an interesting and active research focus for researchers. In this study, we propose a novel loss function to train neural network models to mitigate this critical issue in this important field. Through rigorous experiments on three independently collected datasets of three different medical imaging domains, we empirically show that our proposed loss function consistently performs well with an improvement between 2%-10% macro f1 when compared to the baseline models. We hope that our work will precipitate new research toward a more generalized approach to medical image classification

Effects of different animal manures on yield quality and nutrient uptake by Mustard CV. Agrani

A pot experiment was carried out at the researcher’s net house of Bangladesh Agricultural University, Mymensingh from November 2003 to February 2004 to find out the effects of different animal manure on yield, quality and nutrient uptake by mustard cv. Agrani. The experiment comprised of two levels of cage system poultry manure, deep litter system poultry manure, cow dung and bio-gas slurry viz. 10 and 20 ton ha-1, one control and one chemical fertilizer @ recommended dose. Cage system poultry manure @ 20 ton ha-1 significantly increased the seed and straw yield of mustard and cow dung showed lower performance. In straw and seed the highest uptake of N, P, K, Ca, Mg and S was obtained from cage system poultry manure @ 20 ton ha-1. Protein and oil content was also found higher in this treatment. Seed yield was found to be significantly and positively correlated with branch and effective pod per plant. Protein and oil contents of mustard seeds were increased with increasing level of animal manures though their effects were not significant. A positive and significant correlation was observed between protein and oil contents of mustard cv. Agrani. The overall results suggest that cage system poultry manure @ 20 ton ha-1 gave best performance among the parameters studied

Case report of jelly fish stinging in Bay of Bengal: A report from Bangladesh

Introduction: Jelly fish or jellies are the members of the phylum Cnidaria (Coelenterata), consisting of a gelatinous umbrella-shaped bell and trailing tentacles. Sting contains toxic peptide, pbospholipase A and histamine-liberating factor. Jelly fish stinging in Bangladesh is rare. Yet, from a management point of view, this epizoonozis might gain importance given the ever-growing popularity of seaside fishering and tourism. We are presenting a case of jelly fish contact illness in Cox's Bazar Medical College. Case Report: A 30 year old male patient was stung by a jellyfish while tishering in the Bay of Bengal near Teknaf of Cox's Bazar District on 3rd June' 2013. A couple of minutes later urticaria were formed in the contact area accompanied by a bmniug and sore sensation. Within few minutes be developed severe abdominal pain, bodyache and parestbaesia. Immediate decontmninalion was done by patient himself with sea water though ideally it should be with 5% acetic acid. Routine laboratory investigations show no abnormality except non-significant ST elevation in ECG. The patient was managed conservatively with antihistamine, corticosteroids and antibiotics and recovered completely within four days

Active Physical Practice Followed by Mental Practice Using BCI-Driven Hand Exoskeleton: A Pilot Trial for Clinical Effectiveness and Usability

Appropriately combining mental practice (MP) and physical practice (PP) in a post-stroke rehabilitation is critical for ensuring a substantially positive rehabilitation outcome. Here we present a rehabilitation protocol incorporating a separate active PP stage followed by MP stage, using a hand exoskeleton and brain-computer interface (BCI). The PP stage was mediated by a force sensor feedback based assist-as-needed control strategy, whereas the MP stage provided BCI based multimodal neurofeedback combining anthropomorphic visual feedback and proprioceptive feedback of the impaired hand extension attempt. A 6 week long clinical trial was conducted on 4 hemiparetic stroke patients (screened out of 16) with left hand disability. The primary outcome, motor functional recovery, was measured in terms of changes in Grip-Strength (GS) and Action Research Arm Test (ARAT) scores; whereas the secondary outcome, usability of the system, was measured in terms of changes in mood, fatigue and motivation on a visual-analog-scale (VAS). A positive rehabilitative outcome was found as the group mean changes from the baseline in the GS and ARAT were +6.38 kg and +5.66 accordingly. The VAS scale measurements also showed betterment in mood (-1.38), increased motivation (+2.10) and reduced fatigue (-0.98) as compared to the baseline. Thus the proposed neurorehabilitation protocol is found to be promising both in terms of clinical effectiveness and usability

A Comprehensive Review on the Risk of Metabolic Syndrome and Cardiovascular Disease after Liver Transplantation

Survival rates after liver transplantation have increased dramatically over the past 20 years. Cardiovascular disease is the most common extra-hepatic cause of mortality in the long-term post liver transplant. This is intimately linked with both the higher pre-existing rates of metabolic syndrome in these patients as well as increased propensity to develop de novo metabolic syndrome post-transplant. This unfavorable metabolic profile that contributes to cardiovascular disease is multifactorial and largely preventable. This review explores metabolic syndrome and cardiovascular disease and their contributory factors post liver transplantation to highlight areas for potential intervention and thus reduce the significant morbidity and mortality of patients due to metabolic syndrome and cardiovascular diseas

Urban green and blue space changes : a spatiotemporal evaluation of impacts on ecosystem service value in Bangladesh

The rapid decline in urban green (UGS) and blue space (UBS) in developing countries has led to a widespread degradation of available ecosystem services (ES). However, impacts of UGS and UBS changes on ES tend to vary over space and time, and to date these impacts have not been studied in sufficient detail in emerging economies. By comparing UGS and UBS change patterns with multitemporal Landsat data recorded during the past 30 years (1991–2021), this study has examined the impact of several factors on ES in some of the world's climate hotspots. Although obtaining relevant and accurate information on ES is difficult in many parts of the developing world, this work has developed baseline data suitable for assessing ES loss over five densely populated cities in Bangladesh – Dhaka, Chattogram, Khulna, Rajshahi, and Sylhet. ES loss was quantified in monetary terms using adjusted value coefficients. The topographic and anthropogenic factors driving spatial differences in ES degradation in these cities were analyzed with a geographical detector. The results indicated that the cities experienced a combined monetary loss of USD 628.58 million as a result of specific ES degradation, primarily due to the decline of UGS and UBS. The value of ES loss was notably higher in Dhaka and Chattogram than in the other cities due to marked differences in anthropogenic activities. Population growth, extensive urban sprawl, and the development of dense road networks were identified as the major causes of urban green and blue space loss and consequent reduction of ES. The findings of this study provide important insights which can be used to support the formulation of public policies and management plans aimed at restoring and maintaining sustainable urban ecosystems
