Let x, y be sets. Observe that {〈x, y〉} is one-to-one. In the sequel n denotes a natural number. One can prove the following two propositions: (1) For every non empty topological space T holds T and T ΩT are homeomorphic. (2) Let X be a non empty subspace of En T and f be a function from X into R1. Suppose f is continuous. Then there exists a function g from X into En T such that (i) for every ...

A new re¯ow parameter, heating factor (Q g), which is de®ned as the integral of the measured temperature over the dwell time above liquidus, has been proposed in this report. It can suitably represent the combined e€ect of both temperature and time in usual re¯ow process. Relationship between reliability of the micro-ball grid array (micro-BGA) package and heating factor has been discussed. The...

background around 7% of the world population have diabetes and suffer from its extensive complications. many studies are conducted on the positive effects of aerobic and resistance exercises on the reduction of body performances, but considering the available references, no specific study is conducted on the effect of eccentric exercises on patients with diabetes. objectives the current study a...

The paper presents an overview of the current methodology and practice in modeling and control of the grinding process in industrial ball mills. Basic kinetic and energy models of the grinding process are described and the most commonly used control strategies are analyzed and discussed.

This paper deals with the analysis of broadcast soccer video. To recognize interesting events such as a goal, estimation of ball movements is necessary. It is, however, sometimes difficult to detect a ball by a simple color and shape-based method when it overlaps with players and lines. We therefore develop a method of estimating a ball route during such overlaps by considering spatio-temporal ...

This study discusses kinematic and dynamic precession models for a rolling ball with a finite contact area and a point contact respectively. In literature, both conventions have been applied. In this paper, we discuss in detail the kinematic and dynamic models to describe the ball precession and the radius of a circular rolling path. The kinematic model can be used if the contact area and frict...

One therapies can be done to prevent this use Birth balls. balls fatigue caused by long duration labor. purpose articel was provide an overview effect birth ball exercises on progress first stage This research used Literature Review met...

abstract background: restless leg syndrome prevalence is high among the patients undergoing hemodialysis. due to several side effects of medicational treatments, the patients prefer non-medicational methods. therefore, the present study aimed to investigate the effects of two methods of reflexology and stretching exercises on the severity of restless leg syndrome among patients undergoing hemod...

The purpose of this study was to investigate whether sling-based training focused on rotational exercises would improve shooting performance in outfield handball players during the competitive season, and changes were related altered levels core strength velocity. Twenty-five female (mean age 19.5 ± 2.0 years, height 1.72 0.06 m, body mass 71.5 8.6 kg, experience 10.3 2.4 years), performed 7 m ...
