FEA of automobile suspension system for vibration elimination
In this article the accurate and efficient calculation method for non-stationary random vibration analysis of large complex structures is one of the current research hotspots. According to the linear relationship between input and output of linear structure, the columnar problem of explicit expression of structural dynamic response is first discussed. Based on the above explicit expressions of dynamic response, a FEA method for non-stationary random vibration analysis of large complex structures is proposed for deterministic structural models and stochastic structural models. For the deterministic structure, according to the explicit expression of the dynamic response, on the one hand, the mean and variance of the structural response can be directly calculated by the operation law of the first moment and the second moment; on the other hand, Monte Carlo simulation can be implemented to obtain the structural response. The peak statistic and the solution to the structural dynamic reliability. The random vibration analysis of the vehicle environment was carried out for the equipment mounting structure. Firstly, the characteristics of the vibration environment of the suspension platform are discussed. The random sinusoidal vibration spectrum is transformed into pure random vibration by the principle of equal energy. Then the 3D model constructed by Pro-E software is used to import ANSYS for geometric processing and meshing. Finally, the finite element solution is solved by ANSYS software to obtain the displacement stress response of the structure under the vibration environment of the suspension, and the dynamic strength of the structure is carried out.

Cloud+: A safe and restrained data access control program for cloud
Secure distributed storage, which is a rising cloud administration, is planned to guarantee the mystery of re-appropriated data yet also to give versatile data access to cloud customers whose data is out of physical control. Ciphertext-Policy Attribute-Based Encryption(CP-ABE) is seen as a champion among the most reassuring frameworks that may be used to verify the confirmation of the administration. Be that as it may,the use of CP-ABE may yield an unavoidable security burst which is known as the abuse of access accreditation (for example decoding right). In this paper, we look at the two essential occurrences of access accreditation misuse: one is on the semi-believed specialist side, and the other is supportive of cloud customer. To ease the abuse, we propose revocable CP-ABE based distributed storage structure with express renouncing, planned information getting to and numerous examining capacity alluded as Cloud+.

Meshing technique in FEA for complex shape model and result optimization
In this article the technological application of finite element analysis, meshing is one of the most critical steps. The quality of meshing directly affects the accuracy and speed of the solution. There are three steps in meshing: defining cell properties (including real constants), defining mesh properties on a geometric model, and meshing. Dynamic interaction of a proposed methodology for flexible structures subjected to mobile loads is presented. In the first place, the modeling of a mobile finite element mesh is described, which moves on the contact of a crack in a manner that is integral to the engine that runs through the catenary and, subsequently, the comparison of this methodology is presented against a conventional fixed-mesh finite element model. The simulated case corresponds to that proposed by the standard, obtaining results according to the revalidation intervals proposed by the said standard. The main advantage of the mobile mesh method lies in the fact that for analogous precision, the calculation time is of the order of 4 times less than the classical model.

Correction in Ohm’s law
In physics, we study about fluid flow, Electric current, heat flow, and many more flows but the common thing in all the flows is that it needs some driving force to move something due to which flow will occur and when we observe equations of all these flows, they look similar but if we compare these similar equations of different flows then it looks like that something is missing in defining equations.

The pricing dilemma at Autopress India Private Limited
Auto press India Private Limited, a stainless steel cookware manufacturer, was preparing for a new product launch. All of their efforts were influenced by their vision statement of ‘thoughtfully crafted cookware to transform cooking experiences’. While preparing for the launch of their new product fresh market intelligence emerged which could impact the company’s future strategy, particularly it's product pricing and new product launch strategy. The case demonstrates the dilemma of a decision-maker while framing strategies for growth. Should the company focus on getting the first-mover advantage and later defend itself against competition or should it wait and watch, formulating an attack strategy later? Towards the end, the case outlines the course of action adopted by the company. The case can be used to expose readers to decision making in business and its impact. It helps in understanding the concepts of competitive strategy formulation, channel partnership and product pricing including factors affecting pricing such as competitor’s price changes and perceived value.

Routine and research cohort coverage of vaccines in Tamil Nadu: Implications for the Universal Immunization Program
Immunization coverage in Indian states varies from 24.8 % to 89.7%. Comparison between the routine vaccine coverage with two research cohorts in Tamil Nadu showed the routine immunization system performed well with >80% coverage for EPI vaccines and reasonable timeliness. Given Tamil Nadu’s performance, this and similar states should not be denied access to new antigens, pending improvement in coverage in other parts of India.
