Analytical Modelling and Design of a Mechatronic Cradle SystemIJSRD
Cradle is an appliance which use to carry a baby and oscillate automatically with certain speed for comfort sleep of a baby. Babies sleeps sound in mosses baskets or cradle, as they afford a limited sleeping atmosphere which helps them feel secure. It's important to ensure that swinging cradle are locked when not in use or when baby is unattended, particularly as baby gets older and stronger.Most appropriate time to maneuver baby from a mosses basket or cradle to a cot is between four to six months, or until your baby starts to push up onto their hands and knees and sits unaided. There is a need to develop a advanced automated oscillated baby cradle because the existing cradles are imported and costly. This design and implementation of a new automated oscillating cradle that swings automatically and sends text messages continuously to the linked mobile numbers when baby cries with the assistance of mechatronics system is developed.

Optimization of process parameter for stir casted aluminium metal matrix comp...eSAT Journals
Abstract From the past few years, materials research and development has shifted from monolithic to composite materials, adjusting to the need for reduced weight, low cost, quality, and high performance of the composites. Aluminium metal matrix composite used in areas of aerospace and automotive industries include high performance, economic and environmental benefits. The aim involved in designing the metal matrix composite is to combine the desirable attributes of metals and ceramics. The present investigation has been done to study the effect of different input process parameters namely particle size of alumina, wt. % of alumina and stirring time on the hardness, impact strength and tensile strength. Three parameter i.e. particle sizes of alumina (75, 105 and 150 micron), wt. % of reinforcement (3%, 6% and 9%), stirring time (15, 20 and 25 minute) was used to fabricate different sample of AMMCs by using stir casting technique. Each parameter has three different levels. L9 orthogonal array table used to made different specimen. The effect of these input process parameter on the output response have been analyzed using analysis of variance (ANOVA). The contribution of each process parameters on the hardness, impact strength and tensile strength was analyzed by using ANOVA. The results have shown that the wt. % of alumina, stirring time and the particle size of alumina have a significant effect on the hardness, impact strength and tensile strength. Keywords: MMC’s, pure aluminium, 퐴푙2푂3 particulates, Stir-Casting, Taguchi method
