Numerical simulation for turbulence-driven secondary motion over a streamwise external corner
No full textNumerical simulation, based on a Reynolds Stress Model (RSM), of turbulent flow over a streamwise external corner is presented. This work is an extension of an earlier experimental study (Moinuddin et al., 2004), which identified a pair of counter-rotating vortices placed around the corner of a 6 m long model. Experimental data measured at an early station is used as the inlet condition for the numerical simulation. Mean flow and turbulence statistics from numerical simulation are compared with the experimental data at a downstream station and they are found to be in excellent qualitative agreement. For the scaled mean flow data, quantitative agreement is also very good. Investigation reveals that vorticity production by secondary shear stress is dominant in generating secondary flow over an external corner, which is opposite for the case of an internal corner as found by Xu and Pollard (2001)
METROPOLITAN GOVERNMENT AND IMPROVEMENT POTENTIALS OF URBAN BASIC SERVICES GOVERNANCE IN DHAKA CITY, BANGLADESH: RHETORIC OR REALITY?
No full textUrban basic services, namely water supply and sewerage, power supply, telecommunication, road network etc. are the prerequisites for city living. Efficiency in managing and maintaining urban basic services ultimately dictates the quality of an urban government. In the last three decades, Dhaka‘s urban basic services governance has been tumbling behind the required standard. Specially, in the last five/six years the situation has reached to an alarming state— resulting to a high degree of inconvenience in urban living and loss of potentials in city economy. Frequent malfunctioning, limited capacity to expand, bureaucratic complexity in availing services, lack of public accountability etc. are some of the common characteristics of urban basic services in Dhaka. There is a general understanding in the concerned sphere that fragmented mode of governing these has attributed the service environment with a complex texture. In fact, fragmentation contributed in terms of multiparty involvement, overlapping of responsibility, obsolete organizational planning, monopoly management etc. Presently, Dhaka‘s urban basic services governance can‘t assure better living, competitive business environment and sustainable economic growth. As a potential remedy, adoption of a general purpose ?metropolitan government? mechanism with prerogatives to plan, develop, maintain service provisions; adequately command the service providers; govern development initiatives; realize taxes and revenues have been in discussion for quite a period within the concerned political and administrative domain. This article discusses the rationale, potentials of a general purpose ?metropolitan government? mechanism to improve Dhaka‘s present state of urban basic services. Additionally, the paper attempted to frame out the structure and operational mechanism of the proposed government.Urban basic services, metropolitan government, fragmented governance.

Impact of maternal and neonatal health initiatives on inequity in maternal health care utilization in Bangladesh
No full textBackgroundDespite remarkable progress in maternal and child health, inequity persists in maternal care utilization in Bangladesh. Government of Bangladesh (GOB) with technical assistance from United Nation Population Fund (UNFPA), United Nation Children’s Fund (UNICEF) and World Health Organization (WHO) started implementing Maternal and Neonatal Health Initiatives in selected districts of Bangladesh (MNHIB) in 2007 with an aim to reduce inequity in healthcare utilization. This study examines the effect of MNHIB on inequity in maternal care utilization.MethodTwo surveys were carried out in four districts in Bangladesh- baseline in 2008 and end-line in 2013. The baseline survey collected data from 13,206 women giving birth in the preceding year and in end-line 7,177 women were interviewed. Inequity in maternal healthcare utilization was calculated pre and post-MNHIB using rich-to-poor ratio and concentration index.ResultsMean age of respondents were 23.9 and 24.6 years in 2008 and 2013 respectively. Utilization of pregnancy-related care increased for all socioeconomic strata between these two surveys. The concentration indices (CI) for various maternal health service utilization in 2013 were found to be lower than the indices in 2008. However, in comparison to contemporary BDHS data in nearby districts, MNHIB was successful in reducing inequity in receiving ANC from a trained provider (CI: 0.337 and 0.272), institutional delivery (CI: 0.435 in 2008 to 0.362 in 2013), and delivery by skilled personnel (CI: 0.396 and 0.370).ConclusionsOverall use of maternal health care services increased in post-MNHIB year compared to pre-MNHIB year and inequity in maternal service utilization declined for three indicators out of six considered in the paper. The reductions in CI values for select maternal care indicators imply that the program has been successful not only in improving utilization of maternal health services but also in lowering inequality of service utilization across socioeconomic groups. Maternal health programs, if properly designed and implemented, can improve access, partially overcoming the negative effects of socioeconomic disparities
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
SPATIAL DIMENSION OF SOCIAL EXCLUSION. AN IMPERIAL INVESTIGATION INTO THE RELATIONSHIP OF HOUSING AND SOCIAL EXCLUSION IN THE SLUMS OF DHAKA CITY
No full textSlums are perceived to be heavily populated urban areas characterized by inadequate access to safe water, hygienic sanitation, urban roads, legitimate power supply, poor structural quality of housing and insecure residential status. From that perspective, slums are the clear manifestation of urban poverty. This article emphasize that slums are not just simple expression of poverty but there is a causal process that leads to poverty and inequality. It is not a mere static state describing the inequality rather it is an outcome of structural process causing a chain of disadvantages and deprivations of the community living in the slums. In view of this, this article commences by outlining the key elements of housing in slums and through empirical findings summarises how each of these elements relate to the processes and outcomes involved in social exclusion. Findings from questionnaire interview and in-depth discussion with slum dwellers tend to lend credence to the drawing of a spatial margin of social exclusion. It is understood that slum dwellers’ socio-economic deprivation is closely related with housing elements that further leads to their segregation in social and economic life - thus invigorating a vicious cycle. The systematic exploitation, material deprivation leads to social and economic marginalization of the poor people and results in greater vulnerability of this marginalized group.Social Exclusion, spatial dimension, slums, Dhaka, Housing.

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
