This paper addressed some theoretical and practical issues relevant to the problem of power system load modeling and identification. An identification method is developed in the theoretical framework of stochastic system identification. The identification method presented in this paper belongs to the family of output error models and is based on well-established equations describing load recove...

Demand-side management (DSM) proved to be a conventional concept emanates from the need seen as a means of reducing peak electricity demand and in which a power utility, such as an vertically integrated utility or State Electricity Boards (SEB) manages the demand for power among its customers to meet its current and future needs, so that the utilities can adjourn building further capacity. The ...

Standards-referenced educational reform has increased the prevalence of standardized testing; however, whether these tests accurately measure students' competencies has been questioned. This may be due to domain-specific assessments placing a differing domain-general cognitive load on test-takers. To investigate this possibility, functional magnetic resonance imaging (fMRI) was used to identify...

D emand response, a cornerstone of smart-grid technology, lets consumers participate directly in energy markets by limiting their energy use during periods of emergency or peak demand. In a direct-control demand-response approach, an electricity service provider (ESP) offers consumers discounts or other incentives if they agree to let the ESP send load-shed instructions (LSIs) to specified appl...

STUDY DESIGN Pedicle screw strength or load to failure was biomechanically evaluated, and the geometric characteristics of pedicle screw instrumentation systems were compared. OBJECTIVES To compare the features of pedicle screw systems, and to demonstrate the failure point of the polyaxial pedicle screw head. SUMMARY OF BACKGROUND DATA Many pedicle screw instrumentation systems are currentl...

Evaluating the reliability of loosely coupled Software as a Service through the paradigm of a cluster-based and non-cluster-based web server is considered to be an important attribute for the service delivery and execution. We proposed a novel method for measuring the reliability of Software as a Service execution through load testing. The fault count of the model against the stresses of users ...
