The Right of Getting Bail of an Arrested Person in Bangladesh—A Legal Study of Theories and Practice  [PDF]
Shahidul Islam, Golam Moula
Beijing Law Review (BLR) , 2014, DOI: 10.4236/blr.2014.51004
Abstract:

The essential sense of the Bail in Bangladesh is to release a person from the custody of police and deliver him/her into the hands of the sureties who undertake to produce him in court whenever required to do so. The word Bail is derived from the old French verb “Bailer” which means to “give” or to “deliver”1 (Webster’s Dictionary, 1938). In common Law legal system, it is found that an accused person is to be declared on bail, when he is released from the custody of the officers of the Court. The sureties are bound to produce him to answer at a specified date, time and place, the accusation against him when bail is approved by the competent court. The basic principle regarding release on bail is that an accused person is presumed in law to be entitled to freedom and every opportunity to look after his case, provided his attendance is secured by proper security. However, the paper focuses the idea of releasing an accused on bail in such a case that has been developed as of right of an accused in our country. Therefore, this paper gives emphasis on bail of an accused on legal analysis on theoretical and practical approach and it recommends that the bail granting authority should maintain the principles of law as well as provisions of law properly for the protection rights of an accused.

Arif Istiaque, Shahidul Islam Khan
Energy and Power Engineering (EPE) , 2018, DOI: 10.4236/epe.2018.107020
Abstract: Per capita electricity consumption of Bangladesh is 400 KWh. Of the total population of 160 million, only 40 percent has the access of using electricity. Dhaka city consumes about 40 - 45 percent of the total electricity generation of the country. This study reports the trend of electricity use in the Dhaka city with emphasis on the impact of changing temperature due to urbanization and weather change. Hourly data of electricity demand of Dhaka city and the temperature profile of the city for a period of thirty months have been used for this study. To relate weather data like temperature, humidity, wind speed, wind direction, atmospheric pressure, dew point and visibility etc. with electricity demand of the city about 16,508 data between 2011 and 2017 have been considered. A statistical regression has been done to establish a relation between them. From this study it is found that reduction of only 1°C air temperature could save 81 MV of electricity consumption in Dhaka city. A time series forecast has been done to estimate probable temperature change and subsequent electricity consumption up to year 2020. From the study it has been established that the temperature dependence of electricity consumption in Dhaka city is about 75%.
Detection of Mechanical Deformation in Old Aged Power Transformer Using Cross Correlation Co-Efficient Analysis Method  [PDF]
Asif Islam, Shahidul Islam Khan, Aminul Hoque
Energy and Power Engineering (EPE) , 2011, DOI: 10.4236/epe.2011.34073
Abstract: Detection of minor faults in power transformer active part is essential because minor faults may develop and lead to major faults and finally irretrievable damages occur. Sweep Frequency Response Analysis (SFRA) is an effective low-voltage, off-line diagnostic tool used for finding out any possible winding displacement or mechanical deterioration inside the Transformer, due to large electromechanical forces occurring from the fault currents or due to Transformer transportation and relocation. In this method, the frequency response of a transformer is taken both at manufacturing industry and concern site. Then both the response is compared to predict the fault taken place in active part. But in old aged transformers, the primary reference response is unavailable. So Cross Correlation Co-Efficient (CCF) measurement technique can be a vital process for fault detection in these transformers. In this paper, theoretical background of SFRA technique has been elaborated and through several case studies, the effectiveness of CCF parameter for fault detection has been represented.
Land Rights, Land Disputes and Land Administration in Bangladesh—A Critical Study  [PDF]
Shahidul Islam, Golam Moula, Mominul Islam
Beijing Law Review (BLR) , 2015, DOI: 10.4236/blr.2015.63019
Abstract: The article examines the various ways to ensure land rights and also recommends different mechanism to settle land dispute. It is also intended to highlight the problems of present land administration of Bangladesh and to suggest the reformation of the land administration for proper management of land. Land turns around the life of the people of Bangladesh. The present land laws, land administration and land management in Bangladesh are not only full of intricacy, procedural difficulties and mismanagement but also not accessible and responsive to the interest of the common people of the country. Furthermore, the present mechanism to settle land dispute is not time saving, cost effective, peaceful and sophisticated. If the land laws are made public spirited and land administration is made well-structured in the sense of good governance, e-governance and development, land interest of the common people is upheld and land disputes are settled with public satisfaction and confidence, a revolutionary change may bring about in the socio-economic development of the common people.

Animal Models of Diabetic Neuropathy: Progress Since 1960s
Md. Shahidul Islam
Journal of Diabetes Research , 2013, DOI: 10.1155/2013/149452
Abstract: Diabetic or peripheral diabetic neuropathy (PDN) is one of the major complications among some other diabetic complications such as diabetic nephropathy, diabetic retinopathy, and diabetic cardiomyopathy. The use of animal models in the research of diabetes and diabetic complications is very common when rats and mice are most commonly used for many reasons. A numbers of animal models of diabetic and PDN have been developed in the last several decades such as streptozotocin-induced diabetic rat models, conventional or genetically modified or high-fat diet-fed C57BL/Ks (db/db) mice models, streptozotocin-induced C57BL6/J and ddY mice models, Chinese hamster neuropathic model, rhesus monkey PDN model, spontaneously diabetic WBN/Kob rat model, L-fucose-induced neropathic rat model, partial sciatic nerve ligated rat model, nonobese diabetic (NOD) mice model, spontaneously induced Ins2 Akita mice model, leptin-deficient (ob/ob) mice model, Otsuka Long-Evans Tokushima Fatty (OLETF) rat model, surgically-induced neuropathic model, and genetically modified Spontaneously Diabetic Torii (SDT) rat model, none of which are without limitations. An animal model of diabetic or PDN should mimic the all major pathogeneses of human diabetic neuropathy. Hence, this review comparatively evaluates the animal models of diabetic and PDN which are developed since 1960s with their advantages and disadvantages to help diabetic research groups in order to more accurately choose an appropriate model to meet their specific research objectives. 1. Introduction The term “diabetes” was first coined by Araetus of Cappodocia (81-133AD). Later, the word “mellitus” (honey sweet) was added by Thomas Willis (Britain) in 1675 after rediscovering the sweetness of urine and blood of patients (first noticed by the ancient Indians) [1]. In 1776, Dobson (Britain) for the first time confirmed the presence of excess sugar in urine and blood as a cause of their sweetness. Depending on the pathogenesis, diabetes is classified as type 1 and type 2. The first widely accepted classification of diabetes mellitus was published by World Health Organization (WHO) in 1980 [2] and, in modified form, in 1985 [3]. In 1980, the WHO Expert Committee proposed two major classes of diabetes mellitus, namely: Insulin Dependent Diabetes Mellitus (IDDM) or Type 1 and Noninsulin Dependent Diabetes Mellitus (NIDDM) or Type 2 diabetes (T2D). In 1985, the WHO expert committee omitted the terms Type 1 and Type 2, but the terms IDDM and NIDDM were retained, and a class of Malnutrition-Related Diabetes Mellitus (MRDM) was
Gender Classification Using Gradient Direction Pattern
Mohammad shahidul Islam
Computer Science , 2013,
Abstract: A novel methodology for gender classification is presented in this paper. It extracts feature from local region of a face using gray color intensity difference. The facial area is divided into sub-regions and GDP histogram extracted from those regions are concatenated into a single vector to represent the face. The classification accuracy obtained by using support vector machine has outperformed all traditional feature descriptors for gender classification. It is evaluated on the images collected from FERET database and obtained very high accuracy.
