This paper presents a systematic procedure for modelling and simulation of a power system installed with a power system stabilizer (PSS) and a flexible ac transmission system (FACTS)-based controller. For the design purpose, the model of example power system which is a single-machine infinite-bus power system installed with the proposed controllers is developed in MATLAB/SIMULINK. In the develo...

A sensitive capsaicin sensor was constructed based on a poly(sodium 4-styrenesulfonate) functionalized graphite modified screen printed electrode (PSS-Grp/SPE) in this study. The PSS-Grp and poly(diallyldimethylammonium chloride) functionalized graphite (PDDA-Grp) were easily synthesized by interacting Grp with PSS and PDDA through sonication, and resulted in negative and with positive charges ...

PURPOSE We determined if and to what extent longitudinal changes in lower urinary tract symptoms are related to disease specific and generic quality of life in men. MATERIAL AND METHODS A longitudinal, population based study with a followup of 4.2 years was done in 1,688 who were 50 to 79 years old. Data were collected through self-administered questionnaires, including the Sickness Impact Pr...

Nowadays the competitive pressure increases, with the consequence that the differentiation from competitors by goods or services alone is no longer sufficient. For that reason, companies offer integrated bundles of tangible goods and services, which aim to solve a customer’s problem holistically. These bundles are known as Hybrid Products or Product Service Systems (PSS). In case of IT-enabled ...

Absfrad A neural network-based Power System Stabilizer (Neuro-PSS) is designed for a generator connected to a multimachine power system utilizing the nonlinear power flow dynamics. The uses of power flow dynamics provide a PSS for a wide range operation with reduced size neural networks. The Neuro-PSS consists of two neural networks: Neuro-Identifier and Neuro-Controller. The low-frequency osci...

In this paper we introduce the idea of probability in the definition of a Sequential Dynamical System (SDS), thus obtaining a new concept, that of Probabilistic Sequential System (PSS). Due to its particular dynamic, the Probabilistic Boolean Network (PBN) model has been applied to genetic regulatory networks. The model we introduce combines the sequential aspect of the SDSs and the dynamic of ...

The increasing entwinement of products and services in combined offers – so called Product-Service Systems (PSS) – leads to various requirements regarding the modelling of those systems. Due to these requirements, software support is needed for customer-specific configuration of complex PSS. To provide such software a formal description of the structure of products and services is required. Fur...

GaN films grown on PSS are investigated by XRD, CL, SEM and TEM. There are low threading dislocations (TDs) with larger fill factor, which results in better electrostatic discharge (ESD) yield of LEDs. The effect of growth rate on dislocations in GaN films grown on PSS is investigated by TEM. It is found that dislocations density decreases as the growth rates decrease. And the performance of In...
