This paper presents a method to solve the regrasping problem in the context of object manipulation with a mechanical hand. This problem is met during an object manipulation when one finger reaches the boundary of its workspace or when a collision between parts occurs. Our method synthesizes a new feasible grasp when this problem appears by a sequence of grasps involving the fourth free finger. ...

          In natural resources, economic evaluation is poor in terms of study due to the uncertainty of non-consuming value of resources. In the present study, the evaluation of water, soil and plant resources in watershed management projects and expert questioning was done to enable the projects to be evaluated and prioritized economically. Three sub-watersheds were selected from the Parcel A ...

Spindle poles are discernible by light microscopy as the sites where microtubules converge at the ends of both mitotic and meiotic spindles. In most cell types centrosomes are present at spindle poles due to their dominant role in microtubule nucleation. However, in some specialized cell types microtubules converge into spindle poles in the absence of centrosomes. Thus, spindle poles in centros...

In the paper, we consider local aspects of the entropy of nonautonomous dynamical systems. For this purpose, we introduce the notion of a (asymptotical) focal entropy point. The notion of entropy appeared as a result of practical needs concerning thermodynamics and the problem of information flow, and it is connected with the complexity of a system. The definition adopted in the paper specifies...

In this paper, we motivate the importance of the field of mobile computing and survey current practical and formal approaches. We argue that the existing formalisms are not sufficiently general and powerful because they do not model all necessary concepts of mobility adequately. The main contribution of the paper is, therefore, to identify and define the fundamental concepts of mobile systems b...

A computational approach providing a focus for unsupervised, reactive, data mining is suggested. In data mining, achieving focus is an important issue. This is because there are too many attributes and values in a real database to consider them all. A soft focus is suggested as both data and the focus product may be imprecise. An approach is suggested for unsupervised search controlled by progr...

Rapid technical advances in many different areas of scientific computing provide the enabling technologies for creating a comprehensive simulation and visualization environment for assembly design and planning. We have built an intelligent environment in which simple simulations can be composed together to create complex simulations for detecting potential assembly problems. Our goal in this pr...

the nutritional value of cereal straw can be increased using urea treatments as a source of ammonia. the conventional urea treatment process for cereal straw is a laborious and time-consuming task. it is essential to facilitate or eliminate part of the procedure with the use of machinery. this study examines the mechanical urea treatment of wheat straw and compares chemical components and diges...

In this study, thermo-nonlocal vibration of double bonded graphene sheet (DBGS) subjected to 2D-magnetic field under biaxial in-plane pre-load are presented. The elastic forces between layers of graphene sheet (GS) are taken into account by Pasternak foundation and the classical plate theory (CLPT) and continuum orthotropic elastic plate are used. The nonlocal theory of Eringen and Maxwell’s re...
