It takes a lot of energy to have a good life. For living and working, humans nowadays rely on an abundant and constant source of power. Because energy is depleting at such a rapid rate, it has become important to use heat more efficiently, which necessitates that we preserve. As a result of the global energy crisis, many researchers have worked to improve the efficiency of thermal systems and reduce the size and thus energy consumption rates, which is one of the most critical problems due to the large and continuing increase in consumption, the increasing scarcity of energy resources, and the high cost. A 3 dimensional numerical 3 D simulation was used to evaluate the thermal properties of a heat exchanger managing a combination of dimple ribs. Handling air flow velocity through the channel was varied from 3.97 to 5.80 m s. is the subject of this study. The heat transfer physiognomies of a heat exchanger managing a combination of dimple ribs were studied using the simulation tool ANSYS 19.2. The numerical results showed that the combination of dimple ribs enhanced heat transfer significantly more than the dimple. In comparison, the average Nusselt number of a combination of dimple ribs is 4.28 percent higher than that of a channel with dimpled Plate.

Today, technology is developing at the same rate in line with rapidly increasing human needs. The efforts made to meet these needs make life easier with each passing day and these studies are concentrated on robotic arm studies. The robotic arms work with an external user or by performing predetermined commands. In this study, education health and so on. A field controlled picker robot is designed and applied. Realized picker robot one robot arm and 3 wheels. The robot arm, DC motor, distance sensor, line tracking sensor, L298N motor driver, arduino uno, 3.7V 3A lithium battery are mounted under and above this vehicle chassis. Line sensors allow the robot to start its movement within a certain area without allowing it to move out of the area. When the distance sensors in the front part of the vehicle detects an object within a certain distance, it stops the movement of the motors and starts the robot arm movement which is formed with the help of 4 servos. The robot arm bends to the front at an angle of 150 degrees from the initial state and squeezes the garbage in front of it with the handle. It then turns 180 degrees behind and leaves the object in its chamber. With this picker robot to be realized with this study, garbage collection, cleaning and so on. works can be realized unmanned.

The piston is one of the vital components of IC engine which is subjected to pressure exerted by fuel combustion. Continuous subjection to thermal and structural loads causes failures in piston. The current research reviews various researches conducted to investigate the type and causes of damages developed in piston. The study on effect of piston material, coating material and tribological behavior on piston structural characteristics are presented by various scholars. The researchers have used both experimental and numerical techniques in investigation of piston failures.

Currently, high strength steels are increasingly used in the production of car bodies. Car manufacturers choose steel with good formability, fatigue resistance, and the ability to absorb impact energy. DP dual phase steels verify the specific criteria mentioned above. Resistance spot welding is one of the most common methods of joining high strength dual phase steels. The paper focuses on the comparison of the properties of joints made by resistance spot welding. Selected properties were investigated by tensile test and metallographic observations. HCT600X Z and HCT600X ZF steel sheets were used for the experiments.

The advantage of composite materials over non alloy virgin metals has been on the front burner in the engineering materials sphere. To this ends, various reinforcement materials are constantly been mixed with metal matrix to form new composite materials. Ca2SiO3 is a ceramic material which finds application in medicine, heat and noise insulation, acid remediation, cement production etc. since it possesses qualities needed for the formation of composites, and is largely not researched on, this study aimed to characterize the mechanical properties of the AA 6061 Ca2SiO3 composite for different composition of percentage mix, and to establish a model that would predict the UTS for known values of percentage mix and load. Result of the study shows that 6 Ca2SiO3 - 94 AA 6061 and 24 Ca2SiO3 - 76 AA 6061 possessed the highest modulus of elasticity and are stiffer while 2 Ca2SiO3 - 98 AA 6061 mix had the lowest modulus of elasticity, and is more ductile than other composition mix. Also, it was observed that addition of Ca2SiO3 to AA 6061 T4 greatly improves its mechanical properties and96.43 of the variations in stress experienced by various percentage composition of the composite mix can be explained by the developed model.
