Analysis of driver’s characteristics on a curved road in a lattice model

Abstract: The present paper investigates the effect of driver’s behavior on the curved road via lattice hydrodynamic approach. The basic model for straight road is extended for the curved road and the characteristics of driver’s behavior is incorporated in the lattice model. The extended model is investigated theoretically by the means of linear stability analysis and the effect of curved road and intensity of influence of driver’s behavior on the traffic flow stability is examined. Through nonlinear stability analysis, the modified Korteweg–de Vries (MKdV) equation near the critical point is derived to describe the evolution properties of traffic density waves by applying the reductive perturbation method. Furthermore, the numerical simulation is carried out to validate the theoretical results which indicates that the curved road has a negative influence on the stability of the traffic flow. It is also seen that the traffic jam on a curved road can be suppressed efficiently via taking into account aggressive drivers.

Optimization of powder mixed electric discharge machining using dummy treated experimental design with analytic hierarchy process

Abstract: The analytic hierarchy process (AHP) is widely used for the optimization of multiple responses from an experimental study. In the present study, a method to obtain more reliable global weight of different alternatives has been described for a powder-mixed electric discharge machining (EDM) process. Seven different process parameters were tested to study their effect on material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR) using a specially designed Taguchi orthogonal array that could accommodate factors with varying number of levels. A three-level array L27 was modified to include two-level factors using dummy treatment. The process conditions that affected the three responses were identified and optimized together using AHP for high carbon high chromium (HCHCr), EN31 and hot die steel (HDS) workpiece material. Addition of powder in the dielectric improved the MRR as the electrical conductivity of powder reduces the dielectric insulating strength. Current, powder, and electrode mate...

Blind Signatures Based Secured E-Healthcare System

Abstract: The E-Health cloud paradigm has evolved from the exchange and enhanced sharing of valuable information between various medical institutions, hospital systems and respective care providers. The aim of this system is to reduce the cost and making of efficient process. Preserving privacy of the health record and identity of a patient is one of the prominent concern of the cloud based paradigm. Major bottleneck for a wider reach to potential usages of the cloud is the fear of privacy loss. Patients may not trust the provider of the services and may hesitate to disclose their identities. One of the possible solution is to uphold their anonymity and securely clear their queries. Keeping the aforementioned points in to consideration, in this study, we propose an approach to preserve the identity. In addition to this, the proposed scheme holds the privacy of the patients using a flexible and adaptive approach in the paradigm through an authentication scheme that meets anonymity.
