In this paper, a robust local controller has been designed to balance the power for distributed energy resources (DERs) in an islanded microgrid. Three different DER types are considered in this study; photovoltaic systems, battery energy storage systems, and synchronous generators. Since DER dynamics are nonlinear and uncertain, which may destabilize the power system or decrease the performanc...

Molecular surfaces at atomic and subatomic scales are inherently ill-defined. In many computational chemistry problems, interfaces are better represented as volumetric regions than as discrete surfaces. The geometry of this interface is largely defined by electron density and electrostatic potential fields. While experimental measurements such as chemical bond and Van der Waals radii do not dir...

We investigate a model for planning un­ der uncertainty with temporally extended ac­ tions, where multiple actions can be taken concurrently at each decision epoch. Our model is based on the options framework, and combines it with factored state space mod­ els, where the set of options can be parti­ tioned into classes that affect disjoint state variables. We show that the set of deci­ sion epo...

background: robertsonian translocations are structural chromosomal abnormalities caused by fusion of two acrocentric chromosomes. in carriers of such translocations, different modes of segregations would result in the formation of either balanced (alternate segregation mode) or unbalanced (adjacent 1, adjacent 2, and 3:1 segregation modes) gametes. in addition, there is an increased risk for im...

Die Vorteile der Komponentisierung werden bereits in den Wirtschaftsbereichen der Softwareentwicklung und Produktion genutzt. Der vorliegende Artikel beschäftigt sich mit der Anwendung der Komponentisierung in der Domäne der Dienstleistungswirtschaft, den davon zu erwartenden Vorteilen sowie den Besonderheiten der Dienstleistungsdomäne in Bezug auf die Komponentisierung.

Virtual power plants (VPP) emerge as a new participant that, in order to maximise their visibility and income, represents group of distributed energy resources (DER) the electricity market. However, this DER aggregation brings challenges, such fluctuating renewable sources dependent on weather variables guaranteeing set points. One way deal with these intermittencies is incorporate storage syst...

A mixing rule for the mixtures of hard-spheres is presented which can be reduced to the standard van der Waals mixing rule at low densities. The effectiveness of the mixing rule for the size and energy parameters of lennard-Jones fluid are examined by combining them with an equation of state to calculate thermodynamic properties. The results of calculation are compared with the molecular dy...

Blaise Cronin hat 2013 die Frage formuliert, ob es so etwas wie einen Kanon der Informationswissenschaft gibt. Er schlägt vor, zur Ermittlung des Kanons auch Namensund Sachregister von einschlägigen Lehrbüchern informetrisch auszuwerten. Untersucht wurden englischsprachige Publikationen aus der Kategorie Information Science & Library Science der Fachdatenbank Web of Science sowie neun ausgewähl...

In this thesis, precision measurements of inclusive jet, dijet and trijet cross sections in neutral current (NC) deep-inelastic ep scattering at a centre-of-mass energy of √ s ' 319GeV are presented. The analysis is based on data collected by the H1 detector during the Hera-2 running phase in the years 2003–07, corresponding to an integrated luminosity of 351.6 pb−1. The kinematic phase space o...
