Influence of gaseous fuel induction on the various engine characteristics of a dual fuel compression ignition engine: A review

Abstract: Currently, the unsustainable fossil fuels have been chiefly used for power generation in CI engines. From the standpoint of fossil fuels depletions and environmental concerns, it is imperative to hunt out alternative energy resources that could replace hydrocarbon fossil fuels in the existing engines. In this regards, enormous studies have focused on the utilization of renewable fuels along with conventional petroleum fuel in existing compression ignition (CI) engine. The induction of gaseous fuels under dual fuel mode have emanated as a potential energy carrier to address the environmental aspects related to CI engines. This review focussed to analyze the influence of gaseous fuels (like H2, biogas, syngas) addition to CI diesel engine under dual fuel mode with diesel/biodiesel as a pilot fuel. Various engine characteristics such as combustion, performance, and emission of the dual fuel CI engine using gaseous fuels as a secondary fuel were analyzed and compared with CI engine working under single fuel mode. Findings of some experimental studies have been presented in the form of graphs for selective important parameters as case studies. The overall impression from the review suggests that the performance of the dual fuel CI engine slightly deteriorates while enriching the gaseous fuel, but the improvement in environmental emissions have been reported. Furthermore, various approaches are discussed comprehensively in order to evaluate the performance of dual fuel CI engine along with a check on harmful emissions.

Ensuring Privacy and Security in E- Health Records

Abstract: Mobile medicine and health care have been adopted on a very large scale with support from the influx of medical devices and increased usability of remote health services. These are combined with an approachable interest of the patients and a readily approachable conscience about their healthcare. This leads to a huge set of medical data. These data sets require secure transfer, archival and access. In this study, we have proposed an efficient approach to preserve the identity and also protect the privacy of clinical data using highly effective encryption scheme. Moreover, we have also discussed an authorization framework using access of varying degrees. Medical records are often accessed by various entities with varying degrees of authorization. In this study, we have implemented the AT&T scheme for managing the access control mechanism of patients data. Further, encryption is undertaken using ARCANA, that provides hierarchically satisfied access to various data resources. It utilizes the XACML access model to formulate the access control framework. The primary reason for using this model is the regulation to access the data through AT&T based on XACML policies. In addition to this, the encrypting of medical data using various authorization techniques have been required for the proper data access regulation. Which may impact trust of the users in the e-health paradigm and in turn increase the large-scale usability.
