the present research is representing a template for coordination between human resources strategies and organizational structure and its effect on organizational performance. three alignment (coordination) theories could be identified in management literature; logical pattern, natural pattern and strategic refrence point pattern. in this research after a review on the philosopphical and logical...

Islanded operation of distributed generators is a problem that can take place when they are connected to a distribution system. In this paper an islanding detection method is presented for inverter based distributed generation (DG) using under/over voltage relay. The method is an adaptive one and is based on the change of DG active power reference (Pref) in inverter control interface. The activ...

Analysis of mechanical systems is based on Newton’s laws of motion. Usually, ideal (or point) masses are considered in the analysis, as shown in the Figure 1. Motion is considered with respect to a non-accelerating reference frame, usually a fixed point on earth or another non-accelerating object. The equation of motion for a mass m(t) is based on Newton’s second law which expresses the conserv...

Skin marker-based motion analysis has been widely used for understanding in vivo locomotion and pathological disorders of human musculoskeletal system in biomechanics research and clinical application. Since the knee joint translation is expressed as the displacement of pre-selected reference point on the femur relative to the tibia local coordinate system (LCS), the translation measurement is ...

R + →R is a sign-changing function. In recent years, positive solutions of boundary value problems for difference equations have been widely studied. See [–] and the references therein. However, little work has been done that has referred to the existence of positive solutions for discrete boundary value problems with sign-changing nonlinearities (see []). Usually, in order to obtain posit...

To reduce web access latencies, we propose a new paradigm for caching at the reference point of a document. If a document is referred to from a document , information is cached at to reduce the latency of client accesses to . We focus on two specific instances of this paradigm: caching IP addresses to avoid DNS lookups at clients, and caching information about documents to avoid setting up new ...
