Due to the rapid urbanization of developing countries like Bangladesh the dousing demand is always on a high. This increasing demand opposite to a lack of supply makes houses unaffordable for the middle income groups in the metropolitan cities like Rajshahi. This research is carried out to examine the level of housing affordability of the middle income groups in Rajshahi by using Price to Income Ratio (PIR) approach. PIR is applied to the residential units provided by the Real Estate agencies, which reveals that these are moderate to severely unaffordable for the target group. It is hoped that this paper could be able to provide a clear understanding useful insight on housing affordability for the middle-income group of Rajshahi.</p> Asaduzzaman Md Hameem Sheikh Copyright (c) 2021 American Academic Scientific Research Journal for Engineering, Technology, and Sciences https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-20 2021-09-20 82 1 1 10 A Q-Learning Based Slice Admission Algorithm for Multi-Tier 5G Cellular Wireless Networks https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/6910 <p>Network slicing enables a 5G infrastructure provider (network infrastructure owner) to create multiple separate virtual networks, each tailored at a specific performance requirement, on a common physical network.&nbsp; In this context, slice admission algorithms are required to process slice requests received by the infrastructure provider.&nbsp; These algorithms are tailored to admit and allocate resources to network slices in a manner that results in the optimization of a given objective.&nbsp; In this paper, a Q-learning slice admission algorithm, which maximizes the infrastructure provider’s revenue, is designed.&nbsp; Results show that the designed algorithm learns from its environment, which enables it to acquire knowledge about the multi-tiered cellular network, thus allowing it make optimal slice admission decisions.&nbsp; The results further show that the designed algorithm has superior performance in terms of revenue achieved when compared to algorithms that admit, a) to maximize immediate rewards and b) slices in a random manner.&nbsp;</p> Elizabeth M.

This study aims to identify the contribution of business intelligence in the distribution of information in a strategic way, in decision-making processes within companies. The methodology is presented as a qualitative exploratory research using bibliographic procedures, using a multiple case study strategy, with data collection processes through semi-structured interviews with employees of medium and large companies. size of the state of Rio Grande do Sul, which adopt business intelligence solutions and software in their corporate activity and data analysis is done through content analysis. The research highlights business intelligence as a tool for distributing information strategically in decision-making processes within companies.</p> Daniel Bussolotto Leonardo Da Costa Bagattini Maria Emília Camargo Copyright (c) 2021 American Academic Scientific Research Journal for Engineering, Technology, and Sciences https://creativecommons.org/licenses/by-nc-nd/4.0 2021-09-30 2021-09-30 82 1 19 33 Stability Validation: Righting Moment, Density & List Angle of Floating Objects https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/7070 <p>Finite Element modelling of floating structure for the sake of stress analysis has never been an easy task due to various numbers of factors involved in such structures and the nature of finite element simulations. Typically, if using ‘ALE’ (Arbitrary Lagrangian Eulerian) feature available in LS-DYNA3D explicit code, the floating object will have to float in a fluid 'half-space' of a size which will best represent the effects of the pseudo-infinite sea. The boundaries will need careful consideration, and perhaps employ non-reflecting (energy absorbing) representation. In this representation which will be employed in this paper a study of buoyancy is conducted for verification purposes for modelling afloat. Discussed in this paper is the mathematical verification of the buoyancy of a float, while modelling with LS-DYNA3D features is left to further consideration.</p> Mohamed Abdalla Almheriegh Copyright (c) 2021 American Academic Scientific Research Journal for Engineering, Technology, and Sciences https://creativecommons.org/licenses/by-nc-nd/4.0 2021-10-09 2021-10-09 82 1 34 51 Calculating Environmental Design Loads for Floating Wind Turbine https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/7071 <p>Analysis of complicated structures usually requires; choice of the commercial software as well as good formulation of elements, and loads. The LS-DYNA3D explicit finite element dynamic analysis programme is believed to be good in performing structural analysis of a floating wind turbine and in simulating a full-scale model typical for moderate deep waters. The intended model for which loads are discussed is a middle size power rated floating 3 blades wind turbine elevated at about 50 m above main sea level a top a tripod lattice steel tower firmly resting on a moored floating concrete hull buoy, positioned on a concrete circular disk. The model is intended for use in moderately deep waters of up to 500m. The knowledge of floating offshore wind structures and important features of the LS-DYNA3D code are briefly revised. The theoretical basics for service loads experienced by the floating wind turbine are explored and the environmental loads are quantified and ready for use in the analysis.</p> Mohamed Abdalla Almheriegh Copyright (c) 2021 American Academic Scientific Research Journal for Engineering, Technology, and Sciences https://creativecommons.org/licenses/by-nc-nd/4.0 2021-10-09 2021-10-09 82 1 52 65 Rotor Blade Aerodynamics Forces Modelling for Dynamic Analysis https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/7072 <p>In order to establish a rational method for structural analysis of wind turbine rotor with respect to failure in ultimate loading, either in strength or fatigue fashion. Two famous methods in predicting the complicated nature of the two main lift and drag forces acting ‘normal and tangential’ forces on the rotor blade are discussed and numerical solution ‘iteration’ using the coefficients involved in establishing these forces is presented and, therefore are readily introduced in the analysis stage typically done by dynamics analysis codes.</p> Mohamed Abdalla Almheriegh Copyright (c) 2021 American Academic Scientific Research Journal for Engineering, Technology, and Sciences https://creativecommons.org/licenses/by-nc-nd/4.0 2021-10-09 2021-10-09 82 1 66 77 Genes to Monitor Ecophysiological Parameters for Plants Under Abiotic Stress Conditions https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/7093 <p>In plants, different mechanisms are activated by gene expression in response to abiotic stresses. The great challenge is to study the physiological patterns and the genes involved in each pathway to evaluate the mechanisms used by plant the overcame de stressfully conditions.&nbsp; To mitigate the negative impact of adverse environmental conditions, the particle films technique has become a potential crop management tool for plants to overcome the adverse environmental conditions. The mean goal of this work is to identify genes expressed and involved in different ecophysiological pathways responding to abiotic stresses. GeneMANIA and Cytoscape software were fundamental in the establishment of gene networks. In addition, a graphical representation encompassed other closely linked genes with similar functions. From the perspective of particle film technology, the genes involved in each ecophysiological parameter may, in the future, elucidate new plant response mechanisms, and therefore, a more adaptive molecular response to adverse environmental conditions.</p> Jacqueline Alves Borges Ferreira Renata Silva-Mann Luiz Fernando Ganassali de Oliveira Júnior Copyright (c) 2021 American Academic Scientific Research Journal for Engineering, Technology, and Sciences https://creativecommons.org/licenses/by-nc-nd/4.0 2021-10-12 2021-10-12 82 1 78 98
