The commercial industries of agriculture, mining, construction, and material handling employ a wide variety of mobile machines, including tractors, combines, Load-Haul-Dump vehicles, trucks, paving machines, fork trucks, and many more. Automation of these vehicles promises to improve productivity, reduce operational costs, and increase safety. Since the vehicles typically operate in difficult e...

Over the last few years, language technology has moved rapidly from ‘applied research’ to ‘engineering’, and from small-scale to large-scale engineering. Applications such as advanced text mining systems are feasible, but very resource-intensive, while research seeking to address the underlying language processing questions faces very real practical and methodological limitations. The e-Science...

E-commerce applications are becoming popular day by day as they are working like a virtual shop. Writing good E-commerce application is tedious task and complex also. The applications if made complex are very difficult to maintain. Usability is a very basic concept in the E-commerce application. User has to get the information at one click and with proper feedback. As these are web based applic...

Exploring the phenomenon of surface cracks and abnormal ground behavior during coal mining under gully landforms, laboratory physical similarity simulation models were established to study movement characteristics laws working faces different methods landforms. The results indicate that in cases when a roadway is situated below top slope, corresponding deformation surrounding rock aggravated by...

In elliptic curve cryptography, the problem of computing an integer k from two points on the ellipse namely kp, p the computation of ap+bq+cr+ds, is performed from Shamir’s method. In this paper an algorithm is proposed for computing the minimum joint weight for the integers a, b, c, d, examining them from left to right. Keywords—ECC protocol, JSF algorithm, joint weight, optimality, ISB repres...

called a Parallel Force/Velocity Actuator (PFVA), that combines two fundamentally distinct actuators (one using low gear reduction or even direct drive, which we will call a Force Actuator (FA) and the other with a high reduction gear train that we will refer to as a Velocity Actuator (VA)). The objective of this work is to evaluate the effect of the relative scale factor, RSF, (ratio of gear r...

Interferometric Synthetic Aperture Radar (InSAR) has become the primary remote sensing detection method for monitoring significant surface subsidence and deformation caused by underground coal mining. Time Series InSAR been intensively researched in mining-caused its ability to provide time series, with Small Baseline Subset (SBAS-InSAR) Permanent Scatter (PS-InSAR) being two classical methods....

The Resources and Shaping Forces (RSF) model is developed from a case study in Tigray, Northern Ethiopia, using modified grounded theory. It provides a conceptual framework for identifying, describing and analysing livelihood and natural systems at the community level, and helps link the principles of sustainable livelihoods to those of community development. The shaping forces set of instituti...

In the analysis below, we consider introducing a second contractor early in the JSF program. Our focus is on what makes sense at the beginning of EMD, which should occur approximately a year after this study. For this study, we have cost data regarding the baseline winnertake-all program from both of the JSF contractors plus the JSF Program Office. The alternative is to introduce competition, f...
