Published on 2020
Firuz Ahamed Nahid, Jubaer Alam, Khadiza Akter

Abstract: This paper proposes a multi-step ahead wind speed forecasting approach utilizing Long Short Term Memory Recurrent Neural Network – LSTMRNN (a deep learning technique). Accurate wind speed forecasting is the prerequisite to harvest maximum power from windmills. Proper forecasting of wind speed directly impacts the generation, demand management and unit commitment of windmills. In this research, one year’s historical dataset consisting of wind speed, relative humidity and temperature of thirty minutes interval has been considered to train the proposed LSTMRNN model. The model’s performance has been evaluated by Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and Mean Absolute Percentage Error (MAPE). The performance of the proposed model has also been compared with another machine learning model called Convolutional Neural Network – CNN. The results show that the proposed model can forecast wind speed with much better accuracy in comparison with CNN.

Abstract: Gradual deterioration of structures leads the engineers towards the Structural Health Monitoring system to confirm the existing serviceability scenario, where modal properties are the indispensable part of the process. Modal properties like modal frequency and mode shape from the service providing structure are essential to adjust the numerical finite element model to make the model more like the existing structure. This study built up the mode shape and computed the natural frequency of a precast box girder bridge to compare with numerical model. The selected bridge for this study is situated close to Bangkok city known as canal crossing bridge. A finite element model was developed based on as built drawing, and then, the model was updated with the existing structure’s modulus of elasticity. The ultrasonic pulse velocity test was conducted to obtain modulus of elasticity data. Then accelerometers data were collected under ambient vibration situation from each predefine station to find the modal properties. The study found that mode shape and natural frequency for first mode are similar for both calculated from acceleration data and numerical model.

Developing Passenger Car Unit (PCU) at Signalized Intersection in Context of Bangladesh
Published on 2019
Md. Monirul Islam, Soumik Nafis Sadeek, Jobair Miah, Forhad Hossain

Abstract: Passenger Car Unit (PCU) is an important metric to measure traffic load in transportation system. PCU measures the impact of different transport modes on traffic variables compared to passenger car. It converts the heterogeneous traffic into homogeneous traffic condition. PCU, itself is dynamic in nature, so, it changes in regular basis depending on road environment and traffic condition. PCU varies country to country and even within the country. Developed countries have sufficient research on determining PCU for their own highways, but developing countries like Bangladesh has extreme laggings in determining PCU for its built roadways. So, this research contributes to estimate PCU at signalized intersections based on traffic speed and volume using multiple linear regression model. Our results suggested PCU values of motorbike, autos, buses and trucks, which give different results compared to Highway Capacity Manual (HCM). In some cases, motorbikes possess PCU more than 2.0 which indicates its ample influence of creating traffic anomaly at intersections. Also, bus possesses PCU more than 6.0 which indicates large queue and illegal maneuver of heavy vehicles while entering or exiting into an intersection.

Design of a Broad Band – Stop Filter with Metamaterial as Defective Ground System

Abstract: In this article, a defected ground structure (DGS) is introduced to design a broad bandstop filter to adjust the resonating characteristics by varying the dimension of the structure. The proposed antenna is embedded into a 50Ω microstrip framework. FR-4 (Lossy) is used as a substrate to design the proposed broad band-stop filter which has a succinct structure. The attainment of the antenna is explored both integrally and experimentally. Here Complementary Split Ring Resonator (CSRR) is introduced in the ground layer. It has been monitored that the level of rejection of the filter in the stopband region keeps on going with the introduction of CSRR. This filter is advisable for Xband applications especially on 5.9 to 11.3GHz. The Nicolson-Ross-Weir approach has been applied at the filtering frequency. The effective electromagnetic parameters retrieved from the simulation of the S-parameters imply that metamaterial antenna shows negative refraction bands. This indicates that the proposed antenna has behavior to justify the obligation as a Left Handed medium.

Review Paper on: UASB Bioreactor for Sewage Treatment
Published on 2018
Samiha Binte Shohid, Rowshan Mamtaz and M.Shohidullah Miah

Abstract: : The Up-flow Anaerobic Sludge Blanket (UASB) is a low cost and high rate of treatment process that can produce more bio-energy benefits in terms of biogas production. The UASB treatment process cannot completely remove the organic matter and pathogenic microorganisms. Therefore, a post-treatment process is required for UASB effluent before discharge to the environment to be reused and recycled for agricultural irrigation. The post-treatment of UASB effluent may be an aerobic process, such as a Final Polishing Ponds Unit system (FPU); Trickling Filters (TF); Rotating Biological Contactor (RBC); Bio-Filter (BF); Sand Filter; Sequence Batch Reactor (SBR) and Down-flow Hanging Sponge System (DHS). Alternatively, the post-treatment of UASB effluent may be an anaerobic process such as Anaerobic Bio-film Fluidized Bed reactor; Anaerobic Sludge Thickening and Digestion Process; Anaerobic Hybrid Reactor (AHR); Anaerobic Filter Process (AF) and Dissolved Air Flotation system which are not performed well for the treatment of sewage. Among the systems for treating UASB effluent, Down-flow Hanging Sponge System (DHS) is the best combination process. It reduces significantly the organic load and pathogenic microorganisms. It produces less excess sludge and a final effluent with higher level of dissolved oxygen.

Published on 2018
Monirul Islam, Mahfuzur Rahman, Xiaoying Li and Nahidul Islam

Abstract: : Floods are one of the most destructive natural hazards. Bangladesh and its neighbors in India and Myanmar are highly vulnerable to flood hazards. This study addressed a methodology to assess the relationship between flood hazard vulnerability and relief distribution based on the flood hazard event of 2017 of Bangladesh, using Geographical Information System (GIS). Flood vulnerability maps were developed through a vulnerability score, calculated on the basis of the interactive effect of observed vulnerabilities. Then, flood vulnerability ranks were determined using the ranking matrix of three-dimensional multiplication modes by the interactive effect of three vulnerability maps: flood-affected people, flood-affected infrastructure, and flood-affected crop land. The resulting map revealed the degree of vulnerability of districts to flood hazard events. The analyses exhibit that 49.9% of districts (31 districts out of 64) were to some extent vulnerable to a flood hazard event. Moreover, the GIS technique was used to identify the correlation of flood vulnerability (for people, infrastructure, and crop land) and relief distribution in terms of rice, cash, and dry food. The correlation was determined by overlaying relief distribution data on developed vulnerability maps. The correlation matrix between flood-affected crops land map and relief distribution (cash in BDT) showed the highest congruence (78.85%). Finally, flood vulnerability maps for administrative districts provide relevant information about mitigation techniques and countermeasures against flood damages.

Are We Faithful to the Concept plus Practice of Interdisciplinarity?
Published on 2018
Iván G. Somlai.

Abstract: The preponderance of projects and conflict situations that, at times, reach unexpected complexity may be mitigated by engaging in collaborative and collective conceptualisation, planning and implementation of improvements. One of the most effective ways to ensure proper design and execution of needed work is that a collective of various specialists, likely to be involved at some stage of a project’s lifetime, think and work through ideas presented by one another. History shows that useful insights often arise from orthogonal specialists collaborating in civil society, government and industry. Academe has a potent role in research and development of solutions for complexities in all domains, and should set the example for seeking interdisciplinary solutions.

The Accord and Alliance: Lessons learned after five years of remediation
Published on 2018
Selina Nargis and Khandakar Iftekharul Islam

Abstract: : In response to the tragic Rana Plaza building collapse in 2013, major western clothing brands launched two initiatives: Bangladesh Accord on Fire and Building Safety (Accord) and Alliance for Bangladesh Worker Safety {Alliance). The initiatives sought to remediate the many violations of global electrical, fire, and structural standards among Bangladeshi ready-made garment (RMG) factories supplying these major brands. The agreements between the two initiatives and the government of Bangladesh ended in June, 2018. While meaningful progress was made in the remediation of electrical and fire deficiencies, inspection data from the Accord (up to late 2016) showed at that time that about half of identified structural problems remained unsolved, with a large portion of structural repairs over two years past their deadlines. The pace of remediation for these repairs was much slower than expected. As the Alliance has ended its intensive remediation work and the Accord seeks to begin a threeyear extension, this article provides an update and suggests several lessons to be applied in the future. KEYWORDS: corporate social responsibility; labour rights; Bangladesh; apparel; governance; occupational safety.

Sustainable SupplyChain Management Practices and Challenges of Agri-business in Bangladesh
Published on 2018
Zahir Rayhan Salim

Abstract: Supply Chain Management (SCM) concerns management of the total flow of a distribution channel from supplier to end consumer. It is a set of activities that promotes an effective management of supplier partnerships, meeting customer demands, movement of goods and information sharing throughout the supply network of an industry. The fundamental difference between food supply chains and other chains is the continuous and significant changes in the quality of agro-food products throughout the supply chain network. SCM activities (like service, delivery, and information)pose major difficulties in the agro-food sector. Furthermore, competitiveness in supply chains has been a key issue for organizations and mapping the competitiveness of an organization helps to form a sound basis for sustainable business development. Agro-food industries have to deal with government rules, customer and stakeholders’ interests, seasonality, supply spikes, long supply lead time and perishability. Strategically, rather than competing within low-cost market segments, many agro-food producers are following a differentiation strategy that targets niche market segments like organic foods. Studies have identified that stakeholders such as consumers, retailers, suppliers and regulators are the influential force driving firms to balance environmental aspects of their business with financial performance. The agri-business and sustainable challenges are observed using graphical representation through survey.

Selina Nargis and Khandakar Iftekharul Islam

Abstract: Higher education has a pervasive impact on the entire education system. However, to meet society’s expectations of higher education, the question of quality becomes crucial. It cannot be overlooked. Quality depends on teaching methods and the institutional commitment to create an environment for learning. In addition to teachers, students need physical, social, cultural, and psychological security. Sometimes forgotten is that higher education students are adults. Teaching adults requires adult treatment. This paper is a case study of a leading non-government university in Bangladesh. It assesses the university’s various aspects of quality assessment via a survey of opinion among faculty, students and alumni.

Improvement of Livelihood through Diversified Income Generation
Published on 2017
Abdul Jabber, Selina Nargis and Muhammad Shahjahan

Abstract: This paper evaluates existing modern rice technology adoption and the possibility of increasing household income of resource-poor farms under three diversified production environments in Bangladesh. The potential expansion of modern rice technology has nearly been exhausted in areas displaying favorable production environments. In these areas, there remains scope for enhancing household income through non-rice crop production. On the other hand, the prospect for increased productivity seems elusive in the tidal wetland areas unless flood-resistant rice varieties can be developed and adopted. The output in flood-prone areas devoted to Modern Variety (MV) rice cultivation in the Transplanted Aman (T. Aman) season is 35%, against the national average of 60%. To cultivate a larger area under a flood-prone environment, alternative crops such as vegetables may be cultivated immediately after the recession of flood water. About 38% of the cropped land in drought-prone areas is devoted to MV T. Aman season rice cultivation. Low diffusion of modern technology, caused by infrastructural backwardness, is a prominent barrier to higher agricultural income generation for farms in drought-prone areas of Bangladesh.

Arsenic risk analysis of Bangladesh using geographical information system
Published on 2017
Md. Monirul Islam and Rifat Sumona Mollik

Abstract: Arsenic contamination of ground water is a widely prevalent phenomenon in Bangladesh. It is a form of groundwater pollution due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. Arsenic contamination of groundwater in Bangladesh was discovered by the School of Environmental Studies (SOES) in 1992 (Dhar et al., 1997). The natural contamination of tube wells has led to widespread human exposure to arsenic through drinking water (Dhar et al., 1997). Since consumption of cereals and vegetables is a significant route of human exposure to arsenic, use of groundwater for irrigation of crops raises the question of arsenic uptake in food. The impact of arsenic-contaminated irrigation on rice is especially important as rice is the major staple food, and it may be grown in soil where irrigation has introduced arsenic from groundwater. Arsenic contamination in irrigation would be a toxic to rice leading to reduced yields (Paul, B.K. et. al. 2000). Shallow aquifers (20–70 m) generally have the highest levels of arsenic. The present study dealt with the map of irrigation land coverage, population, arsenic contamination of ground water and then converted the map into the Geographical Information System (GIS) data and maps, and then utilized the arsenic effect on irrigated land coverage and arsenic impact on population. Six categories of arsenic contamination maps were used to assess the levels of arsenic in different areas of Bangladesh. A risk map for administrative districts of Bangladesh was developed using both irrigation and population maps, interacting with groundwater arsenic concentration map (developed by Jakaria 2000)

Published on 2017
Monirul Islam Mahfuzur Rahman Xiaoying Li,Nahidul Islam

Abstract: Bangladesh is one of the most disaster-prone areas in the world. Many different natural disasters - flood, cyclonic storms, tidal surges, droughts, tornados, riverbank erosion, earthquake, water contamination due to arsenic etc. - occur in Bangladesh . Identifying the risk areas with reference to natural hazards causing damage to people in the country, the housing stock and the related infrastructure are most important for infrastructure development. In this study using six of the most common natural hazards namely earthquake, cyclones ,tornadoes, drought, ground water arsenic and floods. we develop a hazard map using the country"s 64 districts. The hazard level is based on a combination of observed local hazard intensity, frequency of occurrences and vulnerability. This study assesses the relative threat, by district, of disasters in Bangladesh, and also the damages, history, severity of these areas, intensities of those natural disasters and housing vulnerability. GIS based disaster database is very crucial and an important aspect for environmental management strategy for plan¬ning and disaster mitigation, preparedness and preventive actions. This study prepared GIS based data sets which were used in the development of multi hazard zoning map. This multi-hazard zoning map will guide officials at the national and regional levels in the formulation of development strategies in multi-hazard ac¬tive zones, land use management, revision and enforcement of appropriate codes and formulation of plans for mitigating measures against hazard risks affecting areas.

Professor Dr. Abdur Rab

Abstract: The day was like any other in 1988. A group of 10-12 people entered the brick-wall, tin-roof restaurant. Minutes later, came the sound of breaking chairs, tables and glasses, as well as a hue & cry. People dashed out of the restaurant and ran away. There was an ‘all quiet’ in the restaurant. About an hour later, leaders of a mob chanted very loud slogans calling on their followers to attack the restaurant, which was stormed with pebbles and bricks from three sides – a three-pronged attack by hundreds of people. Several rounds of gun shots came from inside the restaurant. Despite this, the mob marched on and got closer to the restaurant. Suddenly, people came out of the restaurant and tried to run away. But in vain. One by one they were chased, caught and beaten. Then the attackers helped the injured onto rickshaws and paid the rickshaw pullers – perhaps to take them to a hospital. The attackers entered the restaurant as victors and soon it was humming with loud voices and laughter.

A Study on New Green Methods of Generating Electricity
Published on 2016
Razin Ahmed, Rezoana Arif, and Bishwajit Saha.

Abstract: In this paper, a new method of electricity generation, namely geothermal technique based on carbon dioxide (CO2), is proposed as a partial solution to the power generation needs of Bangladesh. This geothermal technique is an environmentally friendly and safe method of electricity generation compared to some other methods of power generation. Although the cost of the overall system is high, especially for storage of liquid CO2 this high cost can be reduced by using multiple sub-systems of power generation. Every brick field can set up a CO2 trap including a liquefied conversion unit. The pros and cons of the newly proposed method have been discussed extensively with some specific points related to environmental and technical issues. The overall results show that the new method can be useful in Bangladesh to generate an adequate supply of electricity to meet demand.

Under-Five Mortality
Published on 2016
John Richards and Aidan R. Vining

Abstract: : This article analyzes institutional factors associated with under-five mortality at two intervals (2000-03 and 2010-13) among low-income countries, with an emphasis on South Asia. The factors considered fall in four broad categories: health sector inputs (national per capita ratios of professional health care providers and hospital beds, plus public health spending as percent of GDP), performance of public health institutions (access to safe water and sanitary toilet facilities, child immunization, total fertility rate, and access to mosquito nets in malaria-prone countries), social determinants of health (female literacy, percent under $1.25/day and per capita GDP), and effectiveness of national governments in providing services. In explaining changes in mortality levels between decades, four factors are significant: increase in percent above $1.25/day, in vaccination rates and in rates of use of mosquito nets, plus average government effectiveness over the decade. In explaining mortality levels, the top quarter of countries ranked by under-five mortality outperform on average the comparable averages for the three other quarters on nine factors assessed. Achieving top-quarter mortality levels requires superior performance among most of the complex institutional factors such as schools and sanitary infrastructure.

Facebook Marketing Creating Opportunities for Women Entrepreneurs in Bangladesh
Published on 2016
Abu Naser Ahmed Ishtiaque and Sumaiya Minnat.

Abstract: Facebook marketing is the most popular method for online marketing today. You will hardly find any business now without a Facebook presence. The main advantage of Facebook marketing is its vast audience. According to Facebook, there are currently over one billion daily active users on average. The number of businesses using Facebook is growing rapidly around the world, even in our country. From large conglomerates to small businesses, most are on Facebook. Both large and small companies are promoting their products on Facebook. In Bangladesh, like most of the world, Facebook marketing has created opportunities for women entrepreneurs who can now sell different products from their home. Many fashion boutiques have flourished over the last few years solely depending on Facebook for their marketing efforts. Even though the number of Facebook “likes” seems to be related to the popularity of the brand, research shows that the key performance indicator is the Facebook Engagement Factor (F.E.F), i.e., the number of people interacting with the page. This research paper contains survey results and in-depth analysis of 50 fashion boutiques in Bangladesh that use Facebook for marketing their products, the majority of which are run by women. They use paid advertisement, word of mouth, and frequent posts as tools to promote their page. The Facebook Engagement Factor, not the number of likes, is the determinant of how well the page is doing. Small business owners who market their products through Facebook pages thus have to concentrate more on increasing F.E.F than the number of likes of their page in order to be successful.

Published on 2016
M.A. Hashnat Badsha

Abstract: Accra, the capital city of Ghana, is facing on major challenges in both water supply and sanitation. Urban sprawl has outpaced planning of infrastructure and public services by more than a decade due to rapid urbanization and a high population growth rate. As a result, providing water and sanitation services to all in a fast growing, largely unplanned city like Accra is a great challenge. In order to meet these challenges, the Integrated Urban Water Management (IUWM) is introduced and IUWM provides an outline for planning, designing, and managing urban water systems. Although, Accra and Dhaka city are geographically located in two different regions on the earth, but there are some similarities, which have been found between them. Similarly, many differences have also been observed. In addition, the IUWM strategic plans of Accra city have been assessed by the two different engineering tools in order to generate different scenarios before and after considering the strategic directions suggested by the SWITCH—Sustainable Water Improves Tomorrow’s Cities’ Health project. In this regard, Aquacycle13, a modern urban water balancing model has been used in this study where the developed scenarios have showed the future prediction on the basis of the different strategies that must be executed in future. Finally, this study makes an outline of IUWM strategic directions for the Dhaka city in Bangladesh, based on its future challenges and lesson learnt from the existing strategic plan of Accra, Ghana.

Published on 2016
Mohammad Tareq and Razin Ahmed

Abstract: In this paper a rectangular microstrip patch antenna (RMPA) has been designed with coaxial feeding for 5.9GHz resonant frequency. This frequency spectrum is known as Wave Access in Vehicular Environment (WAVE) or IEEE 802.11p. Performance of the RMPA has been analysed by the simulation tool CST Microwave Studio v.2012. Several performance parameters such as return loss, bandwidth, Voltage Standing Wave Ratio (VSWR), directivity, gain and radiation efficiency have been obtained by simulation. This antenna has shown desirable results after a few optimization of design specifications. Designed RMPA resonates at 5.93 GHz and bandwidth has been found as 0.1417 GHz which has fractional bandwidth of 2.39% and that covers IEEE 802.11p band. Directivity and gain obtained at resonant frequency are 5.52 dBi and -0.174 dB respectively. The proposed RMPA radiation efficiency was found as 26.93% and VSWR as 1.05. As an overall evaluation, this antenna’s performance was found to beat a satisfactory level.
