Fatigue life prediction of leaf springs in automotive vehicles using CAE tools

Abstract: Today, the technologies in leaf springs are changing gradually; therefore, new tools are required to keep aligned with worldwide technological requirement. CAE tools are widely used in the automotive industries. The predictive capability of CAE tools has progressed to the point where, physical prototype testing is not required. The objective of the present study is to provide a CAE solution to determine the stresses and deflection under static loading condition. The authors have also reported the CAE solution (using f-fatigue) where the fatigue life of leaf spring has been determined under fluctuating loads. The experiments have been conducted on 65Si7 conventional leaf springs used by TATA Motors. The experimental results have been compared with CAE results. These results are also validated with the SAE, analytical and graphical approach. It was observed that CAE approach provides fatigue life results within 6%–7% and can be alternate of experimental and analytical approach.

Recent Advances in Ad-Hoc Social Networking: Key Techniques and Future Research Directions

Abstract: Ad-hoc Social Networks are formed by groups of nodes, designating a similarity of interests. The network establishes a two-layer hierarchical structure that comprises communication within-group and joining with other groups. This paper presents survey and future directions in four areas of establishing ad-hoc social network using mobile ad-hoc social network (MANET) that includes architecture or implementation features, Profile Management of users, Similarity Metric, and Routing Protocols. The survey presents the need to provide social applications over MANET, optimizing profile matching algorithms of users, and context aware routing protocols. Future directions include multi-hop social network applications that can be useful for users even in airplane mode and notifying over MANET when a user of profile with similar interest is nearby.

Quantifying the influence of FMS on the productivity of a firm

Abstract: The manufacturing organisations adopt flexible manufacturing systems to meet the challenges imposed by today's volatile market standards. An FMS is designed to combine the efficiency of a mass production line and the flexibility of a job shop to produce a variety of products on a group of machines. Productivity is a key factor in a flexible manufacturing system performance. Despite the advantages offered, the implementation of FMS has not been very popular especially in developing countries as it is very difficult to quantify the factors favouring FMS implementation. For its successful implementation, technological considerations, cost justification as well as strategic benefits are to be weighted. Therefore an attempt has been made in the present work to identify and categorise various productivity factors influenced by the implementation of FMS in a firm, further these factors are quantitatively analysed to find their inhibiting strength using graph theoretic approach (GTA). GTA is a powerful approach which synthesises the inter-relationship among different variables or subsystems and provides a synthetic score for the entire system. So using this approach a numerical index is proposed in this work to evaluate and rank the various productivity factors so that the practising managers can have better focus.

Performance Analysis of Reactive, Proactive and Hybrid Routing Protocol Used in Petroleum Tank Over Network Control Systems

Abstract: Remote controlling or wireless communication is emerging technology with innumerable applications. In process industry closing the control loop over the network adds value to the systems but time delay and packet dropout are the two significant constraints while designing the systems. In this paper, the tuning of control valves (actuators) of petroleum pipe line connected to the controller/s through internet is carried out by a method in which uses frequency response of the plant. The performance of the system is compared on the basis of time delay, jitter, and throughput using different protocols as dynamic source routing DSR protocol, ZRP and OLSR protocol. QualNet 5.0 and MATLAB10.0 is used to simulate the above model.

Developing human family tree using SWRL rules

Abstract: Ontology represents explicit specification of knowledge in a specific domain of interest in the form of concepts and relations among them. This paper represents a Human Family Tree Ontology that is designed in two main stages. The first stage covers the domain of the human biological family tree that includes personal information of each person such as name, address, phone number, date of birth etc., and each person's health history which includes lifestyle habits, blood group, diseases that they have been or are suffering from. The second stage includes SWRL (Semantic Web Rule Language) Rules that are helpful in expressing the rich semantic knowledge encoded in the ontology. For this various rules are designed. The ontology is developed using Ontology Web Language and Protege editing tool. Several inputs are given for the testing of well execution of ontology.
