Existence of Tachyons and their Detection
Abstract: It is felt by many that faster-than-light particles (tachyons) exist though none has been detected so far; this lack of evidence raises some doubt as to whether such particles exist. However, it may not be possible to detect these faster-than-light particles even if they exist. Is there any possibility at all in detecting these particles, if they exist? This paper ponders the existence of tachyons and introduces some possibilities for …

Review of Sand Inclusion Defect Analysis to Initiate the Improvement in FNB Casting Process
Abstract: Sand inclusion is an important defect in grey cast iron castings. On an average, this defect accounts for 30 to 40% of the total number of defects arising in the foundries. Sand inclusion is undesirable since it ends up in reducing the strength of the castings and worsens the finish of the casting surface. Hundred or more parameters are responsible for sand inclusion defect and hence it is cumbersome and …
