BACKGROUND Traffic volume and speed is going to be increased in Indian Railways successively, leading to higher stress in staff connected with train operations. The jobs of railway engine pilots come under the category of high-strain jobs, necessitating a need to conduct multicentric study to unfold the factors associated with occupational stress and organizational strategies. MATERIALS AND M...

This paper demonstrates how analysis of a software development process specification can support effective planning for accomodating mobile users of process-centered software development environments. The paper presents a flow graph analysis-based approach to responding to a user who asks to detach from a high-speed wired link, and to continue working through a lower speed interruptible link. W...

Adjusting operating temperature of the engine in the steady state and during warm-up improves fuel consumption and reduces engine emission through higher operating temperatures. Also it can improve thermal comfort by faster cabin heater performance. Thermal fluid analysis by 1-D simulation is an effective tool for studying the control of the entire cooling system and optimization of engine perf...

Only a limited amount of work has been done on issues of optimum experimental design in hierarchically structured data, in spite of the importance of design efficiency. We illustrate these issues by a fresh analysis of Holliday’s well-known engine mapping experiment. This experiment investigated the relation of automobile engine performance, as measured by engine torque vs. spark advance, to ad...

With the rapid increase of websites and internet users, the traditional search engine will face great challenge in the real-time search, response speed and the storage of mass pages. However, the search engine deployed in the cloud can solve these shortcomings due to cloud computing with two major advantages in mass data processing and mass data storage. By analyzing the open-source cloud compu...

Abstract: One objective of this paper is to illuminate fuel economy and emission improvement mechanisms of variable cam timing systems and analyze their effects on engine control system design. By retarding or advancing the cam phase one can vary the engine volumetric efficiency, as well as the amount of exhaust gas that dilutes the air charge. Combining these effects with intake manifold and e...
