Smartphone-based Calorie Estimation From Food Image Using Distance Information

Personal assistive systems for diet control can play a vital role to combat obesity. As smartphones have become inseparable companions for a large number of people around the world, designing smartphone-based system is perhaps the best choice at the moment. Using this system people can take an image of their food right before eating, know the calorie content based on the food items on the plate. In this paper, we propose a simple method that ensures both user flexibility and high accuracy at the same time. The proposed system employs capturing food images with a fixed posture and estimating the volume of the food using simple geometry. The real world experiments on different food items chosen arbitrarily show that the proposed system can work well for both regular and liquid food items

Reasons behind Dropping out of Slum Children from Non-formal School in Dhaka

In South Asia, numerous slum children were deprived of education upon several socio-economic grounds, and many children still dropout of non-formal schools despite receiving free non-formal education. This study aims to explore the reasons for dropping out of non-formal schools and the socio-demographic situation of slum children in Dhaka City. Fifty non-formal dropout slum children were selected conveniently as participants employing a mixed research design. A semi-structured schedule of questionnaire and interview was used as instruments for collecting data. Both qualitative and quantitative data were collected simultaneously to explore the slum children's dropout situation. Twelve reasons of their dropout have been reported. In addition to explaining the reasons for their dropping out, two frameworks were presented in detail. Most slum non-formal students dropped out of their schools for the pulling out factors and reasons related to household. Recommendations for reducing slum children's school dropout and persuasive strategies for future work in this field have been addressed. Keywords: Non-formal School, Dropout, Slum Children, Non-formal Education

Fuzzy-AHP Modelling of Risk Factors for Tanneries in Bangladesh to Adapt Industry 4.0

Bangladesh is marching forward in the way of the Industry 4.0 adaption process with its strength of human assets and long productive experiences. Bangladesh\u27s traditional tanneries are under pressure to change their unfavourable working conditions into safe and productive ones. The study aims to determine the main risk factors of tanning industries from a related literature review and analyse these challenges to adapt the Industry 4.0. A Fuzzy Analytic Hierarchy Process (Fuzzy-AHP) based Multi-Criteria Decision Making (MCDM) methodology is developed to analyse and determine the most and the least critical risk factors. In addition, the purpose of this paper is to provide recommendations for mitigating the risk factors associated with the conversion of a tannery to Industry 4.0. Paired comparisons were created among the criteria for collecting 12 experts’ judgments from different tanneries at different levels to progress the methodology using Fuzzy-AHP geometric mean process. The results have shown that the main four risk factors for Industry 4.0 are: Lack of Commitment from Top Management and Policy Makers\u27 Support (47% weight); Lack of Ability to Meet up Initial Cost (29% weight); Lack of ICT-Based Knowledge and Training (15%); and Availability of Cheaper Workforce (9% weight). The judgments given by the experts are acceptable since the paired comparisons are tested with the consistency ratio checking mechanism

A Review on Embryonic Development of Inland Fishes of Bangladesh

The early developmental pattern of inland fishes of Bangladesh are not well studied though it has a great importance in fisheries and aquaculture sector. The embryonic study provides interesting information on further growth and health of the fish and considered as an essential component for optimization of fish seed production by natural and induced breeding. Therefore, the current review work has been undertaken to provide a detail information on embryonic development of important inland fishes of Bangladesh. Information was collected from published scientific papers, un-published Masters and PhD dissertations from universities, popular articles and other published and grey literature. Diameters of unfertilized egg of the reviewed fish species were found to be 0.5 to 1.3 mm and fertilized egg were 0.49 to 1.6 mm. Shapes of the egg were also variable from species to species. There is little information available on egg activation and egg micropyle of fish species of Bangladesh. The fertilization rate of different fishes ranged from 40.1% to 93.9%. There are different stages of early development in different species and time needs to complete the stages also vary. The timing of post hatching development by metamorphosis was found to vary based on the fish species from several days to weeks. Different factors like temperature, photoperiod, DO, seasonality and presence of chemicals in water were found to affect the early development of fish. The review included eighteen inland fishes and unearthed useful insights of their embryonic development and influence of different factors. As we expect, the outcome of the study would provide a baseline and would be very useful in conducting further research on the embryology of indigenous fishes of Bangladesh.&nbsp
