Application of Traffic Calming Devices in Developing Countries: Learning Lesson from Bangladesh  [PDF]
Farzana Rahman, Tri Basuki Joewono, Shahidullah Al Masum
Journal of Transportation Technologies (JTTs) , 2018, DOI: 10.4236/jtts.2018.82007
Abstract: Traffic calming devices become more favorable for many cities to manage traffic in urban as well as neighborhood areas. Many developing cities already initiated the implementation, while the process has a wide variation in both quality and quantity. The objective of this study is to evaluate the justification of speed humps in urban roads and also to recommend a guideline for installation of speed humps as a traffic calming device in Dhaka city, Bangladesh. It was found that there are vast variations in the implementation, while general public also express an immense disparity of perception about devices quality and suitability and their agreement. Lesson learned from Dhaka City shows that selecting an appropriate placement and dimension of the traffic humps is an urgent requirement to be solved by government by providing standards, guidelines, and policy when there is an initiative to implement or improve traffic calming application.

Journal of Transportation Technologies (JTTs) , 2017, DOI: 10.4236/jtts.2017.72008
Abstract: Bus systems provide a versatile form of public transportation with the flexibility to serve a variety of access needs throughout an urban area. Efficient operation of the public transport is a key factor for the improvement of living condition in Dhaka city. Transport service performance should be assessed from the passengers’ perspectives to evaluate these perceptions in transportation planning. The exploration of service quality of bus is essential in order to provide a better service in future. The objective of this research is to access overall customer satisfaction in public bus transport of Dhaka city. A questionnaire survey was conducted in five locations in Dhaka city. Bus users’ satisfaction was analyzed by discrete choice logit model towards quality, reliability, safety and security and service provided by buses functioning in Dhaka city. The result indicated that more than half of the respondents believed that the present condition of bus service is not satisfactory. In case of the quality of buses, people think that the body and sitting arrangement of the buses are uncomfortable. Regarding the safety and security condition, main three reasons of dissatisfaction of passengers’ are unsafe driving practices, poor boarding and alighting facilities and lack of law enforcing agencies surveillance. Reasons which make the service unsatisfactory include irregular service provided by buses, regular overcrowding, lack of good standard buses and lack of cleanliness. In spite of these negative views, users’ possessed a positive attitude for buses which is the low travel cost.
Enhanced Partial Dominant Pruning (EPDP) Based Broadcasting in Ad hoc Wireless Networks
Ashikur Rahman,Md. Endadul Hoque,Farzana Rahman,Sabuj Kumar Kundu
Journal of Networks , 2009, DOI: 10.4304/jnw.4.9.895-904
Abstract: In many applications of ad-hoc wireless networks, one often has to broadcast the same message to all nodes. The major goal of any broadcasting algorithm is to minimize the number of retransmissions, i.e., to accomplish the goal with the minimum amount of traffic in the network. In addition to reducing the bandwidth expense needed to convey the message to all the nodes, this objective will try to minimize the total amount of energy spent by the nodes on this communal task. This is of paramount importance in sensor networks, which are often built of disposable nodes, whose life-time is directly determined by the efficiency of their power management scheme. In this paper, we present a heuristic broadcast algorithm dubbed EPDP, for Enhanced Partial Dominant Pruning, and demonstrate its superiority, in terms of the total number of retransmissions, over other solutions addressing the same issue.

Computer Science , 2015,
Abstract: Students' satisfaction plays a vital role in success of an educational institute. Hence, many educational institutes continuously improve their service to produce a supportive learning environment to satisfy the student need. For this reason, educational institutions collect student satisfaction data to make decision about institutional quality, but till now it cannot be determined because student satisfaction is a complex matter which is influenced by variety of characteristics of students and institutions. There are many studies have been performed to inspect student satisfaction in the form of college services, programs, student accommodation facility, student-faculty interaction, consulting hours etc. So, still we cannot have a standard method to know what is going on about satisfaction in the case of a core course. In this research we determined the attributes that heavily affect student satisfaction in a core course of computer science and the current status of other attributes as well.

Abstract: Childhood overweight and obesity, is an emerging public health concern in developing countries like Bangladesh. However, regular television watching by child’s mother and its impact on excess weight gain or overweight and obesity to their offspring is not reported elsewhere. The aim of the present analysis was to determine the socio-demographic characteristics among overweight and obese children based on those mothers who watch television regularly and compare this finding with malnourished and well-nourished under-5 children. A total of 20,800 under-5 children were enrolled during 1996 to 2012 in the Diarrheal Disease Surveillance System (DDSS) of Dhaka Hospital of International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b). Mean weight-for-age z-score (–1.61 vs. –2.30; mean difference: ?0.69; p < 0.001), height-for-age z-score (–1.42 vs. –1.99; –0.57; <0.001), weight-for-height z-score (–1.59 vs. –1.07; –0.53; <0.001), BMI-for-age z-score (–1.09 vs. –1.61, –0.52; <0.001) differed significantly between the children whose mother did and did not watch television regularly. Under-5 children whose mother watched television regularly (2%) compared to those who did not (1%), had 2.28 [(95% CI-1.61 - 3.24) p < 0.001] times increased odds of being overweight and obese. Television watching of mothers is associated with childhood overweight and obesity and is one of the most public health concerns in Bangladesh. These changes may be in part of better socio-economic condition, changes in life style behaviour and dietary pattern.

Research Journal of Biological Sciences , 2012, DOI: 10.3923/rjbsci.2010.345.349
Abstract: Glycemic and Insulinemic responses to potato and sweet potato by estimating their Glycemic Index (GI) and insulinemic index (measured by c-peptide) from Bangladeshi origin were investigated in Type 2 Diabetic Mellitus (T2DM) patients. Based on serving size in the Bangladeshi society the GL of those two food items were also calculated. About 10 T2DM subjects (male 5, female 5, age 44±3.16 years, BMI 24±3.85, HbA1c 6.78±1.79%, M±SD) studied under a cross-over design, consumed equi-carbohydrate amount of the vegetables and white bread (WB, as reference food) with a run in period of 7 days between the consecutive items. The test meals (potato, sweet potato and WB) containing 50 g of total carbohydrate) were given to the participants for ingestion within 10 min with 200 mL water. Serum levels of glucose were estimated at 0, 15, 30, 45, 60, 90, 120, 150 and 180 min, respectively. GI and GL (serving size of the food 22 g for both potato and sweet potato, respectively in Bangladesh) were calculated by standard formulas. Serum glucose was measured by glucose-oxidase, c-peptide was used as the marker of insulin and was measured by chemiluminescent ELISA and HbA1c (glycosylated hemoglobin) by High-Performance Liquid Chromatography (HPLC) method. Classification of GI was taken from the international table (GI: high = 70, medium 56-69 and low = 55; GL: high = 20, medium 11-19 and low = 10). Both plain potato and sweet potato showed significantly higher serum glucose response compared to that of reference food (iAUC (M±SD): 234±65 in bread vs 361±81 in Potato and 416±47 in sweet potato; p<0.015 and 0.001, respectively). The similar glycemic response between plain potato and sweet potato was reflected in their GI values: 162±50 and 191±66, respectively. The basal values of serum insulin in all the 3 groups were matched. The substantially higher glycemic response and GI values in potato and sweet potato were not the consequence of a suppressed insulin response. The GL of potato and sweet potato were 8 and 11, respectively. Considering the economical aspect, crop production, high satiety, therapeutic advantage and for food diversity potato can be recommended for healthy as well as T2DM subjects especially for their low fat and high micronutrient content and beneficial effects in insulin response for some verities observed in this study. In spite of high GI, considering potential source of carbohydrate current consumption can possibly increased from a minor vegetable to the most important vegetable in the diet, as a mixed meal or and an occasional partial substitute for rice.

Quantitative Biology , 2015,
Abstract: In the last decade a number of algorithms and associated software have been developed to align next generation sequencing (NGS) reads with relevant reference genomes. The accuracy of these programs may vary significantly, especially when the NGS reads are quite different from the available reference genome. We propose a benchmark to assess accuracy of short reads mapping based on the pre-computed global alignment of related genome sequences. In this paper we propose a benchmark to assess accuracy of the short reads mapping based on the pre-computed global alignment of closely related genome sequences. We outline the method and also present a short report of an experiment performed on five popular alignment tools based on the pairwise alignments of Escherichia coli O6 CFT073 genome with genomes of seven other bacteria.
