The aim of the smart grid is to achieve more efficient, distributed and secure supply of energy over the traditional power grid by using a bidirectional information flow between the grid agents (e.g. generator node, customer). One of the key optimization problems in smart grid is to produce power among generator nodes with a minimum cost while meeting the customer demand, known as Economic Disp...

Corrosion of steel reinforcement is one the most widespread pathologies that leads to a loss structural performance reinforced concrete (RC) members. Thus, understanding mechanical consequences this pathology great importance. In past decades, many studies have been performed assess influence corrosion on quasi-static behavior RC structures. However, few investigations carried out characterize ...

Introducing kindergarten children to the engineering design process (EDP) is an important objective of early STEM education. Studies indicate that often miss crucial steps testing and optimising during EDP do not persist in making solutions better. The present study explores how children’s goal awareness, self-evaluation ability, domain-specific content knowledge, spatial skills intelligence re...

Curved beam bridge is a kind of irregular structure, which has the advantage adapting to complex terrain, but it more vulnerable damage than regular under earthquake. This paper investigates vulnerability curved continuous girder bridges action bidirectional earthquake horizontal earthquake, and difference between side pier intermediate analyzed. Fragility assessment performed using an incremen...

Several methodologies for assessing seismic risk extract information from the statistical relationship between intensity of ground motions and structural response. The first group is represented by measures (IMs) whilst latter engineering demand parameters (EDPs). higher correlation them, lesser uncertainty in estimating damage structures. In general, IMs are composed either a single (scalar-ba...

The route discovery process of on-demand routing protocols is based on route request (RREQ) packets that are propagated using either an unrestricted broadcast (flooding) or an expanding ring search. We apply two enhancements to this basic process aimed at reducing the overhead incurred in the dissemination of RREQs. First, we apply the Enhanced Dominant Pruning (EDP), which is a distributed con...

UKBM is a learning tool using the Semester Credit System (SKS) and small unit that arranged sequentially by involving study time units. This research focused on developing with Engineering Design Process (EDP) approach in physics high school. The purpose of this was to produce valid determine effectiveness through increasing students' STEM literacy after EDP-based UKBM. uses development (R&...
