Inviting Nature into Academic Learning: Exploring the Possibility to Activate the Introvert Courts inside the University Buildings DOI:  https://doi.org/10.30564/jaeser.v5i1.4240 Abstract Established on peripheral sub-urban area of Sylhet city, Shahjalal University of Science and Technology is a public university well known for its beautiful natural environment and diversified landscape with green hillocks, waterscape, forests and biodiversity. But, the academic buildings of the campus were planned in an introvert way that the common void courts remain disconnected from the outside natural environment. Although designed with positive intention, most of the courts remain unused maximum the time of a year. As the campus natural environment is getting richer day by day and users prefer to spend more time in outside environment, it is high time to integrate nature into the academic learning. This research aims to explore the possibilities of these void courts to be incorporated with the ou

Analysis on the Structural Type of Large-span Steel Truss Bridge Specially Designed for Cables DOI:  https://doi.org/10.30564/jbms.v3i1.3141 Abstract When the installation of cables and pipelines needs to go across rivers, bridges are usually adopted to support the cables and pipelines for crossing the rivers. The measure can make full use of the space resources and have no effect on the flow pattern of rivers. For this reason, analysis on the structural-type design of a large-span steel truss bridge specially used for cables has been performed. The numerical results indicate that the stayed-cable bridge with steel truss beam and concrete main tower has better performance and improved structural type caparisoned with that of the beam and arch bridges, and the construction of the major beam can be without the temporary support.

Volcanogenic Deposits of Non-ferrous Metals in the Lesser Caucasus and Eastern Pontides DOI:  https://doi.org/10.30564/jgr.v3i4.3572 Abstract The paper presents brief characteristics of geological environments of ore deposit occurrences in Turkey, Georgia and Armenia. They can be attributed to Kuroko-type deposits, being distinguished by the character of ore accumulation. To the west, in Turkey, there are epigenetic and hydrothermal-sedimentary copper-zinc deposits that were formed in deep restricted basinal settings. An example of the latter is the Chayeli deposit. To the east, in the Caucasus, we have predominantly only epigenetic deposits. Besides, in the Bolnisi mining district (Georgia) there is the Madneuli deposit which represents an example of polyformational deposit. Here, within the restricted territory, have been concentrated: barite, barite-polymetallic, gold-bearing secondary quartzite, large-scale stockworks of copper ores. Judged by the 87Sr/86Sr ratios, some volcanites

Data Analytics of an Information System Based on a Markov Decision Process and a Partially Observable Markov Decision Process DOI:  https://doi.org/10.30564/jcsr.v5i1.5434 Abstract Data analytics of an information system is conducted based on a Markov decision process (MDP) and a partially observable Markov decision process (POMDP) in this paper. Data analytics over a finite planning horizon and an infinite planning horizon for a discounted MDP is performed, respectively. Value iteration (VI), policy iteration (PI), and Q-learning are utilized in the data analytics for a discounted MDP over an infinite planning horizon to evaluate the validity of the MDP model. The optimal policy to minimize the total expected cost of states of the information system is obtained based on the MDP. In the analytics for a discounted POMDP over an infinite planning horizon of the information system, the effects of various parameters on the total expected cost of the information system are studied.

Outdoor Air Quality Monitoring with Enhanced Lifetime-enhancing Cooperative Data Gathering and Relaying Algorithm (E-LCDGRA) Based Sensor Network DOI:  https://doi.org/10.30564/jcsr.v5i1.5383 Abstract The air continues to be an extremely substantial part of survival on earth. Air pollution poses a critical risk to humans and the environment. Using sensor-based structures, we can get air pollutant data in real-time. However, the sensors rely upon limited-battery sources that are immaterial to be alternated repeatedly amid extensive broadcast costs associated with real-time applications like air quality monitoring. Consequently, air quality sensor-based monitoring structures are lifetime-constrained and prone to the untimely loss of connectivity. Effective energy administration measures must therefore be implemented to handle the outlay of power dissipation. In this study, the authors propose outdoor air quality monitoring using a sensor network with an enhanced lifetime-enhancing cooper

Research on Precipitation Prediction Model Based on Extreme Learning Machine Ensemble DOI:  https://doi.org/10.30564/jcsr.v5i1.5303 Abstract Precipitation is a significant index to measure the degree of drought and flood in a region, which directly reflects the local natural changes and ecological environment. It is very important to grasp the change characteristics and law of precipitation accurately for effectively reducing disaster loss and maintaining the stable development of a social economy. In order to accurately predict precipitation, a new precipitation prediction model based on extreme learning machine ensemble (ELME) is proposed. The integrated model is based on the extreme learning machine (ELM) with different kernel functions and supporting parameters, and the submodel with the minimum root mean square error (RMSE) is found to fit the test data. Due to the complex mechanism and factors affecting precipitation change, the data have strong uncertainty and significant nonlin
