Abstract

Spatial inequality of development is an important issue in Bangladesh. In this study a set of sectors-education, infrastructure, health, and economy-and sectoral components/indicators were selected aiming at investigating the spatial inequality scenario of Bangladesh. All components/indicators of each sector were weighted overlaid using ArcGIS tool. Finally, the overall spatial inequality of development was generated overlaying all the sectoral inequality maps. The spatial inequalities were revealed categorically from the highest overlaid cell value as the most lagged area to the lowest value as the most advance area. A serious centralized character towards the capital Dhaka was identified almost in all the sectors in spatial inequality maps of Bangladesh. The overall spatial inequality map identified a total of 16 districts in the comparatively ‘lagged area’ category; and 44 districts in the category of the ‘moderate area’. Only one district (the capital Dhaka) was identified in the category of ‘most advance area’, while three districts (Chittagong, Gazipur, Narayanganj) found in the ‘advance area’ category. Most of the lagged districts were identified in the north-west and north-east parts of Bangladesh. Besides, the districts of Chittagong Hill Tracts (Bandarban, Khagrachari, Rangamati) were also found most lagged..

Abstract

This paper reports a comparison of different types of springs used in MEMS based capacitive accelerometers. In this work MEMS based Single-axis accelerometers are designed using different Suspension systems. Analysis of the structure is done for resonant frequency of 2kHz. Analytical modeling of the different suspensions is presented for the specified frequency. Stress, displacement and capacitive analysis of the accelerometer is done. The sensitivity of the accelerometer with parallel beam  suspension is 70nm/g, 50nm/g for folded beam suspension and 35nm/g for serpentine beam suspension. Hence parallel beam suspension has 0.7 times improved sensitivity than folded beam and 2 times better than serpentine suspension accelerometer. Whereas the stress obtained for folded beam is better than the other two. Hence  Parallel beam suspension is preferred for higher sensitivity and accuracy whereas Folded beam suspension is preferred for greater structural stability By comparing these devices, it is concluded that a compromise on certain parameters is required in order meet the requirements. If there is higher displacement sensitivity then there is lower mechanical stability and vice versa. The simulations are carried out using COMSOL Multiphysics.

Abstract

Pure thiourea barium chloride (TBC) crystals were grown by slow evaporation from aqueous solution and slow cooling (0.1oC/ day). The growth was carried out for 21 days by keeping the bath at a temperature of 39oC.   Optimal molecular structures are explored by DFT / B3LYP method with 6-31G (d, p) based synthesis. Hyper conjugative interactions, charge delocalization and intra molecular hydrogen bonding have been analyzed using natural bond orbital (NBO) analysis. Moreover lower in the HOMO and LUMO energy gap explains the eventual charge transfer interactions taking place within the molecule, which influences the biological activity of the compound and also energy serves as a measure of the excitability of a compound, the smaller the energy gap, the more easily the compound will be excited.  Electronic structures were discussed and the displacement of the electron density was determined. Second – order perturbation theory analysis of the intra molecular bonds of Methyl Orange doped TBC were derived.

Abstract

The recent rise in fire incidents in Anambra State has resulted in displacement, stress, psychological, adverse effect on the lives of its inhabitants and a devastating consequence on the economy.  The objectives of the study include examining the estimated value of properties loss due to fire outbreak within the study period and to employ the Random Forest regression model to predict the estimated losses associated with fire disasters in Anambra State. The data for the study was a secondary data obtained from the records Department of the Anambra State Fire Service, Headquarters Awka. The study used the Random Forest regression method to analyze the data obtained in this study. The Random Forest regression analysis was employed to predict the estimated value of properties loss (EVPL) due to fire outbreak. The explanatory variables used for the prediction of the response variable were Number of victims (NV), Percentage of Plain Land (PL), Population Size (PS), Population Density (PD) and Actual Revenue by LGA (ARLGA). The findings of the study revealed that EVPL has a higher Skewness and Kurtosis followed by NV and the least was found to be PL. Further result revealed that the percentage of variance explained was 12.03%, sum of square error (SSE) was 31.41, root mean square error (RMSE) was 0.7236 while the R-square was 59.18%. This result implies that the model was moderately positively adequate since it recorded a positive coefficient of determination. The findings from the variable importance analysis showed that Population Density played a major role in the estimation of the response variable followed by the number of victims while population size was found to be the least important variable for estimating the response variable.

Abstract

The energy crisis is a severe problem facing the world, including Indonesia. Along with the times, innovation is needed to implement sustainable energy. Non-fossil energy sources have not been widely used, and efforts are still needed to utilize these energy sources. The waterwheel was the first device used in water production. One of the innovations for the sustainability of non-fossil energy is to make a waterwheel. There are still several waterwheels in Indonesia, but an investigation is needed to determine their condition. So in this study, investigating the breastshot water wheel uses a nozzle-based construction with variations in the degree of inclination of the spray against the TSR value. The results showed that the greater the inclination of the nozzle angle, the higher the velocity of the water flow when it enters the wheel. Adding water speed to this wheel will increase the momentum and tangential force. An increase in the tangential force will increase the wheel's torque so that the wheel strength will increase. This increase in power will, of course, result in greater efficiency, thereby increasing the tip speed ratio (TSR).

Abstract

In this study, the multipurpose objective of development in the Anambra River basin was examined. The study's goals are to determine the net benefits of the various objectives under each purpose currently carried out by the Anambra River Basin, to identify the best way to achieve the goals, and to show, through logical and mathematical reasoning, how money could be allocated to the various goals of a dam project in Anambra State effectively. Economic Efficiency (EE), Regional Economic Redistribution (RER), Social Well-Being (SW), Youth Empowerment (YE), and Environmental Quality Improvement are the objectives taken into account in the study (EQI). The optimization problem in the multi-purpose-objective development of the Anambra State river basin was solved utilizing the multi-start optimization method. The study showed that the basin would achieve enormous financial benefits if it used its N15.0 billion strategic development budget over four years for various purposes as illustrated. The results showed that the following allocation of the five purposes should be optimized simultaneously for an N15.0 billion four-year strategic development fund: EE should receive N0.762 billion, RER should receive N0.594 billion, SW should receive N0.649 billion, YE should receive N0.683 billion, and environmental quality improvement should receive N4.768 billion.  It was found that Environmental Quality Improvement was allocated the higher amount while Regional Economic Redistribution was allocated the least amount for the development. The study's findings recommended that the management of the basin stop the practice of allocating funds to various uses at their discretion, which has led to significant oversight and the improper distribution of scarce resources. As a result, every fund distribution must be justified using logic and mathematics. To increase the accuracy of the data, the Anambra State River Basin Development Authorities must intensify record-keeping activities.

Abstract

A neural network is a data processing system consisting of a large number of simple and highly interconnected processing elements in an architecture inspired by the structure of the cortical regions of the brain. Therefore, neural networks can often do things that humans or animals can do, but traditional computers are often lousy. This research discusses brain tumors that can be detected by artificial intelligence. Stroke includes the sudden death of brain cells due to lack of oxygen, blockage of the circulatory system, or severance of flexible pathways to the brain. Therefore the need for action that must be faster to be able to detect this deadly disease. The method used is a Neural Network which can collect knowledge by detecting patterns and relationships between data and learning experiences. So that the detection process is carried out more quickly and the patient can be given medical action as soon as possible. In the study I conducted brain stroke from the number of strokes with a value of 0 4733 and 1 out of 248. This research has a test conducted by conducting epoch training from 1 to 300, the highest score accuracy is in epoch 1 and 2 with more high scores.
