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.

A simulated and experimental validation of a tube and shell heat exchanger device, used for heat transfer laboratory, was developed. The validation is carried out by means of computational fluid dynamic applying the turbulence formulation k-ω for shear stress transport, different treatments were carried out in which two types of systems were varied, a parallel flow system and a counterflow system. Among the results obtained are the temperature profiles for all the treatments, the flow lines through the systems, and the results show the comparison of temperature profiles for the techniques used, obtaining average error margins between samples of 4%
Multiuser superposition transmission (MUST) provides the flexibility of using the same radio resources for two users with varying distance from the serving base station. This article presents a performance evaluation of MUST using three waveforms; namely: cyclic prefix orthogonal frequency division multiple access (CP-OFDM), and two newly proposed frequency division multiplexing (FDM) filter solutions for 5G, which are universal filtered multiple access (UFMC) and filtered OFDM (F-OFDM). The evaluation process takes into consideration two main criteria; throughput and peak to average power ratio (PAPR). Two scenarios have been simulated and studied. In scenario one, six user equipment (UEs) and two base stations (BSs) were simulated in orthogonal multiple access (OMA) environment, while in scenario two, 12 UEs and two BSs were simulated in MUST environment. The simulation results show that the far UEs can be served with sufficient data rates to provide basic connection, without much degradation in the throughput of near UEs. Furthermore, the comparison shows a 53.5% increase in the overall throughput of MUST NOMA compared to OMA with CP-OFDM scenario, and a gain of 12.58% and 52.7% for UFMC and F-OFDM, respectively
