Experimental Test Results on the Effect of Ultrasonic Waves on Defects in Car Bearings: The Effect of Defect Size
Abstract: To check for defects in car bearings, they are identified and measured by sound waves that are affected by the defect. Based on sound, it is called ultrasound technology because it uses high frequencies. High frequencies are the basis of ultrasound. Two features are useful for low-speed cars, which by definition usually have poor signal tolerance. High frequencies are sensitive to the effects of sound waves. In addition, the ultrasound …

Dynamic and Fatigue Analysis of Engine Crank Shaft by Using FEM Approach
Abstract: The internal combustion (ICE) engine crankshaft is a high-volume manufacturing component with a complicated shape. This converts the piston's reciprocating displacement into the crank's rotating motion. In this research, an effort is made to investigate how geometry modification might increase the fatigue life of a single-cylinder engine crankshaft. SOLIDWORK software was used to construct the modelling of the original and optimised crankshaft, which was then imported for analysis into ANSYS …

Study to Evaluate Effectiveness of Structured Teaching Programme on Knowledge Regarding Hypertension and Its Management among Hypertensive Clients in Selected Hospitals of Amritsar
Abstract: Hypertension is an important risk factor for cardiovascular and renal diseases including stroke, coronary heart diseases, heart failure and kidney failure. Hypertension—the silent killer-remains asymptomatic until its damage effects are seen. It has been figured that almost one third of B.P.-related deaths occur from coronary heart disease. It is also estimated that a 3 mm Hg reduction in systolic B.P. could lead to an 80% reduction in stroke mortality and …

Mayer–Rokitansky–Kuster–Hauser Syndrome: Case Report
Abstract: Mayer–Rokitansky–Kuster–Hauser syndrome (MRKH) or vaginal agenesis or Mullerian agenesis is a congenital malformation characterized by a failure of the Müllerian duct to develop, resulting in a missing uterus and variable degrees of vaginal hypoplasia of its upper portion. Müllerian agenesis (including absence of the uterus, cervix, and/or vagina) is the cause in 15% of cases of primary amenorrhoea. Affected patients usually have normal ovarian function, but present with primary amenorrhea …

Experimental Investigation of FSW on Al 6061-T6 MG Dissimilar Joints
Abstract: Friction Stir Welding (FSW) is a solid-state joining technique that has shown significant potential for welding dissimilar materials, such as aluminum and magnesium alloys, which are difficult to join using conventional fusion welding methods due to large differences in their physical, thermal, and metallurgical properties. During FSW, contact between the rotating, wear-resistant tool shoulder, the pin, and the work piece produces frictional energy. Additional thermal energy develops because of intense …

Dynamic Matrix Control Versus Nonlinear ModelPredictive Control for the Van de Vusse ContinuousStirred-Tank Reactor: Diagnosing and Correcting aCost-Function Pathology That Masked NMPC’sTrue Performance
Abstract: The Van de Vusse reaction in a continuous stirred-tank reactor (CSTR) is a benchmark for nonlinear multivariable control, but its narrow operating envelope creates a trap for nonlinear model predictive control (NMPC): when the setpoint step is small relative to the plant’s reachable range, a standard quadratic NMPC cost function can make zero control action mathematically optimal, even with a perfect prediction model. This paper documents that failure mode, traces …
