The US Federal Circuit court of appeals has dissolved the preliminary injunction that for several years kept bar-nesandnoble.com from offering its Inter-net customers the one-click shopping that Amazon.com offers. The one-click patent, one of the most derided business-method patents, took a heavy thrashing from the Federal Circuit, but it hasn't been knocked out by complete invalidation yet. Th...

Q.1. What is hot working ? State its principles, advantages and disadvantages. Ans. Mechanical working of metals above its recrystallisation temperature is known as hot working. Advantages : 1. Larger deformation can be accomplished and more rapidly by hot working since the metal is in plastic state. 2. Porosity of the metal is considerably minimised. 3. Concentrated impurities, if any in the m...

Numerous researchers from the field of agricultural engineering use mathematical models for the description of processes. Because of the existing many systems and processes, there is a possibility of making different types of models. Their systematic may be found in the Pabis [1985] and Powierża [1997] books. Once the form of a model is fixed, what remains is the testing of the correctness of t...

Supply chain management is a very dynamic operation research problem where one has to quickly adapt according to the changes perceived in environment in order to maximize the benefit or minimize the loss. Therefore we require a system which changes as per the changing requirements. Multi agent system technology in recent times has emerged as a possible way of efficient solution implementation f...

We study numerically and analytically the coarsening of stripe phases in two spatial dimensions, and show that transient configurations do not achieve long ranged orientational order but rather evolve into glassy configurations with very slow dynamics. In the absence of thermal fluctuations, defects such as grain boundaries become pinned in an effective periodic potential that is induced by the...

As a major part of farming sustainability, the issues of grain production and its quality improvement have been important in many countries. This paper aims to address these issues in China. Based on the data from the main production provinces and by applying the stochastic frontier analysis methodology, we find that the improvement of transportation and the use of agricultural machinery have b...

The ability of helium gas displacement pycnometry to characterise the reduction adsorbed water density with increasing bentonite content was tested. For this purpose, after obtaining grain (which assumed be constant), an intensive campaign 45 experiments carried out two bentonites for a total 90 determinations, very consistent results. Furthermore, retention curve one fully characterised by 95 ...
