Energy Management through Bio-gas Based Electricity Generation System during Load Shedding in Rural Areas

The scarcity of energy especially electrical energy is an acute problem and hinders the modern economic development of a country. Most of the time only a small percentage of peoples have access to use continuous electricity supply. But in this modern era, all types of arena like economies, households and companies have extensive demand for electricity which is due to industrialization, extensive urbanization, population growth, rising standard of living and modernization of the agricultural sector of a country. Electricity generation from bio-gas plant through cowdungs of a dairy firm can mitigate the electricity demand to some extends in rural areas, where biogas plant will act act as a backup supply especially during load shedding. This research paper proposed an electricity generation system from bio-gas, which can work as a secondary source of the electricity for all electrical appliances of a particular area in a cost effective manner

Relationship between Personality Traits of the Urban Poor Concerning Solid Waste Management and Household Income and Education

This study analyzes the relationship between knowledge, attitude, and behaviour of the urban poor householders concerning solid waste management systems and monthly household income and education. To attain the objective, the study employed statistical techniques such as t-tests of equality of means, one-way ANOVA, chi-squared „likelihood ratio“ test and simple descriptive statistics. The findings show that the urban poor communities with low income and education have been proven to behave in ways matching with and conducive to environment-friendly solid waste management, for instance, by practicing recycling and waste source reduction. This study also proves that the urban low-income communities generally have a very proactive role from a sound environmental management perspective, as they are the main recyclers and source-reducers of solid waste. The study suggests that policies should be formulated to focus on promoting knowledge, education, skills, and empowerment of the urban poor as means of promoting their living conditions

Compressive Behaviour of Concrete by Using Bagasse Ash From Sugar Mill

The materials which are useless and unwanted is called waste product and this waste product is a burden and harmful to the environment. Sugarcane bagasse ash (SCBA) is one kind of waste which can be termed as the residue left over from burning sugar cane bagasse. The utilization of this waste may be very economical and can also solve the environmental problem. Silica and alumina are the main element of SCBA which is used as a pozzolanic material. This recycling procedure of SCBA reduces environmental pollution and this is also considered the cost-effective material. In this paper, SCBA replaces the cement as a weight of 5%, 10% and 15% which is considered. After completing the compressive strength test, the result shows that the compressive strength increases when 5% cement is replaced by sugarcane bagasse ash and this is the correct replacement of cement

Wave Retail Banking Effect on Customer Satisfaction in Retail Supply Chain in Bangladesh

Abstract-Purpose: The purpose of this study is a clarification of changes of supply chain management (SCM) in public organizations and the nature of change management (CM). The paper also examines and demonstrate the trust influencing CM in technology adoption in Bangladesh pubic organizations. The aim of this paper is, consequently, to identify precarious success factors for CM. Theory: In this study we focus on the adoption of technology such as the Technology Acceptance Model (TAM), highlighted the need to broaden the scope of theoretical mechanisms. Method: In this study, we obtained the empirical data necessary to validate the theoretical framework. In total of 460 self-administered questionnaires were used to derive public sector responses in Bangladesh in their perceptions of trust and aspects of change management. Originality: This study an outline of CM in TA projects is recognized based on the literature review and empirical evidence. Significance: This study will enhance the service and management of public organization. Besides that, it will provide quality service for public organization. Finally, it will introduce technology supply chain in organization management. Outline: the paper concludes with a presentation of the study’s, framework and contributions as well as the stream of upcoming research

Challenges of Warehouse Operations: A Case Study in Retail Supermarket

The research represents a case study on Bangladesh retail supermarket. The study demonstrates the intricacies of warehouse management practice. It elaborates the dynamics of retail supply chain and the spiral affects how warehouse can play a significant role. In addition to this, the study identifies external factors, market trends, and possible barriers which influence the overall performance of warehouse operation. The paper is based on secondary data that encompassed three major retail chains in Bangladesh. The paper also reveals opportunities to improve warehouse performances in terms of planning, design and operation. The authors demonstrate some recommendations for industry practitioners to achieve a higher level of productivity in warehouse managemen

Design, Construction and Performance Study of a Solar Assisted Tri-cycle

Solar energy is one of the important sources of renewable energy which can be a feasible alternative to fossil fuels. There are many works has been done in order to incorporate solar energy to everyday transportation including tricycle. However, most of the tricycle develops are expensive and not feasible for developing countries. In this study, a cheaper solar tricycle with more capability of utilizing the solar energy is designed for developing countries. The main content of the tricycle is Solar PV panel, Brushless PMDC motor, controller, and battery. The power transmission of the solar tricycle is also simple. It is found that tricycle serves 24% back up for running, by the solar panel. Also, the total construction cost of the tricycle is only 240$ with near about zero impact on the environment. This paper highlights the advantages of the dual mode of charging, including the economic and environmental feasibility of the tricycle

Exploring Challenges of Deploying BERT-based NLP Models in Resource-Constrained Embedded Devices

BERT-based neural architectures have established themselves as popular state-of-the-art baselines for many downstream NLP tasks. However, these architectures are data-hungry and consume a lot of memory and energy, often hindering their deployment in many real-time, resource-constrained applications. Existing lighter versions of BERT (eg. DistilBERT and TinyBERT) often cannot perform well on complex NLP tasks. More importantly, from a designer's perspective, it is unclear what is the "right" BERT-based architecture to use for a given NLP task that can strike the optimal trade-off between the resources available and the minimum accuracy desired by the end user. System engineers have to spend a lot of time conducting trial-and-error experiments to find a suitable answer to this question. This paper presents an exploratory study of BERT-based models under different resource constraints and accuracy budgets to derive empirical observations about this resource/accuracy trade-offs. Our findings can help designers to make informed choices among alternative BERT-based architectures for embedded systems, thus saving significant development time and effort
