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.

The present work is focused on the sensory quality of jam produced by watermelon rind. Response surface methodology (RSM) was used to optimize the sensory quality of watermelon jam by the formulation of ingredients such as watermelon rind (400-800g), sugar (400-800g), pectin (10-30g) and citric acid (2-4g). Results showed that the model fit was significant (p < 0.05) and there was satisfactory correlation between actual and fitted values. Data obtained from RSM on watermelon rind (WMR) jam production were subjected to the analysis of variance (ANOVA) and analyzed using a second order polynomial equation. The response sensory analysis such as color, taste, aroma and texture was studied during experimental runs of WMR jam processing. The highest sensory score was given by jam production with watermelon rind 585.8568g, sugar 618.1818g, pectin 20.1010g and citric acid 2.7677g. Jam produced under the optimum conditions for sensory score was again subjected to evaluation of sensory values and the results were compared with the RSM predictions
One of the fabrication technique is welding. Based on Material, welding can be divided into welding the same Material (similar welding) and welding with different materials (dissimilar welding). Based on the joining process, welding can be divided into arc welding with wrapped electrodes (SMAW), submerged arc welding (SAW), gas arc welding (GMAW), tungsten arc welding (GTAW) and others. This study presents a review of dissimilar welding with the Shielded Metal Arc Welding (SMAW) process. Dissimilar welding has been applied in various industries such as automotive, power plant, construction, etc. SMAW Method is one of the methods for dissimilar welding is used for this paper. SMAW is a procedure that uses an arc to accomplish the weld between a covered electrode and a weld pool. This paper aims to contribute and improve the basic theory of dissimilar welding, especially the SMAW method. This paper also explains the SMAW welding process, the equipment used, and the Material and electrodes used. As a result, this review showed the SMAW process capable of welding dissimilar Material due to easy and simple equipment. It can be used for all metal combinations on dissimilar welding likely low carbon steel and stainless steel, or stainless steel and stainless steel, etc. Weld quality can be performed with a destructive test (hardness, bending, and tension test), Microstructure (SEM and EDS), and non-destructive test (Magnetic particle, radiography, ultrasonic test). Furthermore, the effect of dissimilar welding with the SMAW process on microstructure and mechanical properties will be investigated
This research intends to investigate the watershed morphometry factors that affect the watershed base flow. The methodology consists of data screening on rainfall-flood hydrograph (single peak), separating the direct run-off and base flow, identification the characteristic of watershed physical parameter, and finding the relation between the watershed physical parameter and base flow. The result shows that watershed area (A), watershed circumference (P), main river length (Ld), total river length (Ltot), and topography factor (T) are influencing the watershed base flow
Inserting the shoot-through duty cycle within the inverter switching pattern is the most important process in controlling the Z-Source Inverter (ZSI) output voltage because it has many limitation and boundaries in the values and the manner of producing. This paper presents a comprehensive study of switching techniques and switching patterns of the ZSI. The most important switching techniques of the Z-source are presented in this paper to overview the features and characteristics of these techniques presented in the literature. Many simple and complex methods are reviewed in this paper as a comparison study, considering the controlling of the ZSI and reduce the effect of the voltage stress on the switching devices
The great advancement in digital applications has led designers to be able to control industrial processes using the programmable logic controller (PLC). This research employs PLC controller to drive two induction motors in three synchronized forms though AC drive supplied from single phase supply. The forms are, master-slave operating with same speed or different speeds and when the second motor runs at preset ratio of the first machine. Theoretical implementation is driven through Matlab/Simulink with a known parameters 3-ph induction motor while the hardware implementation is driven using PLC controller and unknown 3-ph induction motor parameters. The control drive has been tested under different operating conditions, and its reliability has been proven though practical results
