100 Years of General Theory of Relativity
Abstract: The General Theory Relativity is the generalization of the Special Theory of Relativity. This theory certainly is one of the most extraordinary achievement of the scientific world till date. Einstein's discovery of General Theory of Relativity is itself series of dramatic incidents, from the beginning until it’s proven. The theory reviewed our understanding of gravity, light and time, and paved the way for many modern technologies. The observational evidence is …

Stress Intensity Factor in Artificially Damaged Structures
Abstract: The presence of cracks in macrostructures creates heterogeneity which manifests itself by a change of the state of stress and strain in the structure. A crack in vibrating structures can lead to premature failure if it is not detected in time. Researchers have been working on the dynamics of cracked structures for decades to be able to monitor the structure and diagnose that fault at the earliest possible stage. In …

Optimization of Effects of FMEA to Enhance Quality and Efficiency of CNC Machines in Valve Manufacturing Industry
Abstract: Failure mode and effects analysis (FMEA) is a systematic method for identification and preventing problems of products and process before its occurrence. FMEA focus on preventing defects, enhancing safety and increasing customer satisfaction. The FMEA needs to define parameters such as Severity (S), Occurrence (O), Detection (D) and Risk Priority Number (RPN). The conventional FMEA and grey relational analysis approaches are applied in this work. The rankings of the failure …

Electronic Power Assisted Steering System
Abstract: Electric power steering (EPS or EPAS) is designed to use an electric motor to minimize the effort by providing steering assist to the driver of a vehicle. Sensors detect he motion and torque of the steering column, and a computer module apples assistive torque via an electric motor coupled directly to either the steering gear or steering column. This allows varying amounts of assistance to be applied depending on driving …

Analytical Modeling of Brick–Mortar Couplet
Abstract: This paper is a presentation of the finite element modeling of stress in a brick–mortar couplet. The brick–mortar couplet here serves as a meaningful substitute for a brick wall structure. In this work, the basic steps in derivation of the element stiffness matrix for a plane stress problem using the displacement approach are presented. The main purpose in the work is to verify the nodal displacements, which in turn would …

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 …
