Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.
Technology Reports of Kansai University (ISSN: 04532198) is a peer-reviewed journal. The journal covers all sort of engineering topic as well as mathematics and physics. the journal's scopes are
in the following fields but not limited to:
Radio propagation is essential for emerging technologies with appropriate design, deployment and management strategies for any wireless network. Empirical propagation models have found favour in both research and industrial communities owing to their speed of execution and their limited reliance on detailed knowledge of the terrain. These models are used extensively in signal prediction and interference analysis. High prediction errors of these empirical models arise when they are being deployed to an environment different from the one they are initially designed for. This work therefore provides the error bounds on the efficacy of five different empirical models at predicting path loss for Ekiti and Lagos states in Southwest, Nigeria. The Ekiti State Television (EKTV) was employed for Ekiti State while Lagos State Television (LTV) was used for Lagos State. The models used for this analysis are Okumura-Hata, Hata- Davidson, COST-231, CCIR and ECC-33 models. Measurement of TV signal path loss was conducted in Lagos and Ekiti States. The measured path loss for two routes in Lagos and Ekiti States was compared with the selected predictive path loss models. The performance of the predictive path loss models were evaluated using the mean error and root mean square error. The Hata-Davidson predictive model was discovered to have the least error bounds in all the routes considered for the two States
Concrete construction process faces a lot of problems seeking them continuously can raise the efficiency of construction process and concrete members. One of the major problems which occurred in concrete structure projects is the movement of the wood mold during construction, the concrete member may deform and case a deterioration of other surrounding structural members. This study investigates one of the critical problems in the building of Al-Masbah Telecom Center Company in Iraq. The twisting of the upper ends of the columns 25 mm was occurred while the lower end remains fixed, this rotation was achieved due to the movement of the wooden mold during construction process. This certain problem required re-analysis and extensive study to take a decision regarding the adequacy of column capability to carry applied load and redistribution of stresses in all structural members. The structural calculations revealed that there was no effect due to end twisting on column capability to carry the applied loads and structure stability. This study focuses on repairing one of a telecommunications concrete buildings in Baghdad (capital of Iraq); the damage in building was carried out due to twisting of columns as a result of movement in the mold during construction. This study includes an illustration of the damage causes and repairing methods. It is also includes a theoretical calculations of capacity of these columns after damage occurrence, and comparing the results with capacity of undamaged columns. This study also dealing with a reanalysis of the structure carrying capacity for applied loads
