A method is presented that compensates for manipulator end-point errors in order to achieve very high position accuracy. The measured end-point error is decomposed into generalized geometric and elastic error parameters that are used in an analytical model to calibrate the system as a function of its configuration and the task loads, including any payload weight. The method exploits the fundame...

The aim of this paper is to introduce and characterize pgrαregular spaces and pgrαnormal spaces via the concept of pgrαclosed sets. It also focuses on some of its basic properties and discusses on separation axioms between pgr-T0 and pgr-T1. An attempt has been made to make a comparative study with other usual separation axioms. Mathematics Subject Classification: 54C10, 54C08, 54C05

This paper, based on a Multipurpose survey on a large national sample of Italian households which has made possible to analyse parent-child and grandparent-child dyads, explores the impact of marital instability on relationships with adult children and with grandchildren. As in other countries, the impact is more negative in the case of divorce than in case of widowhood and, in both cases, more...

The vortex-sheet model of leading-edge separation previously applied to flat-plate delta wings has been applied to thick delta wings in the form of rhombic cones. The simplifications introduced by the use of slender-body theory and an asymptotic treatment for the core of the vortex have been retained. The results show that the vortex sheet leaves the wing tangentially to the lower surface. The ...

Background The killing of women by intimate partners (also known as intimate female homicide or intimate femicide) is the most extreme form and consequence of violence against women. Globally, gender differences are found in homicide patterns. Men are at greater risk of being killed than women and this is mainly done by other men. Women, on the other hand, are primarily killed by the opposite g...

Various components of air have been separated for different purposes for their easy availability in the atmosphere. Among those components Nitrogen separation process is very important in chemical engineering sector since it has wide usage in different processes. There are various technologies that are used for the separation of nitrogen. Among those most common is via LINDE-HAMPSON cycle. This...

In the present paper, we introduce topological notions defined by means of α-open sets when these are planted into the framework of Ying’s fuzzifying topological spaces (by Lukasiewicz logic in [0, 1]). We introduce T 0 −, T 1 −, T 2 (αHausdorff)-, T 3 (α-regular)and T 4 (αnormal)-separation axioms. Furthermore, the R 0− and R 1− separation axioms are studied and their relations with the T 1 − ...

W hen I hear the phrase “humanimplantable electronics,” I must confess that I feel a bit queasy. It conjures up a more extreme image of pervasive computing than is usually justified. However, my perspective is that of a relatively healthy person in his 40s, without any physical handicaps. If my hearing was impaired or my heartbeat arrhythmic, I might be keen to find a remedy—and, at this time, ...

In this paper, we compare many kinds of randomized algorithms and simultaneously inspect their data to calibrate an impulse force between two rigid bodies. One is an object handled by a manipulator tip, and another is an object fixed in a 3-D environment. A real impulse is obtained from an experiment via a six degrees-of-freedom force/moment sensor mounted on a tip of a seven degrees-of-freedom...
