Process management can increase the efficiency and effectiveness of process activities by structuring and coordinating their execution. However, its application can become problematic in dynamic environments such as software engineering, since rigidly pre-specified process models are not capable of adequately handling dynamic aspects of the processes. Therefore, this work presents a declarative...

urban settlements and their connectivity will be the dominant driver of global change during the twenty-first century. in an attempt to assess the effects of urban growth on available land for other uses and its associated impacts on environmental parameters, we modeled the change in the extent of gorgan city, the capital of the golestan province of iran. we used landsat tm and etm+ imagery of ...

dense medium cyclone is a high capacity device that is widely used in coal preparation. it is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in dmcs complex. in this article the flow pattern simulation of dmc is performed with computational fluid dynamics and fluent...

Abstract— The dynamic behavior of power systems is affected by the interactions between linear and nonlinear components. To analyze those complicated power systems, the linear approaches have been widely used so far. Especially, a synchronous generator has been designed by using linear models and traditional techniques. However, due to its wide operating range, complex dynamics, transient perfo...

--This paper presents the Analysis of Dynamic Characteristics of switched reluctance Generator using MATLAB, a widely used simulation tool. Component models are addressed and their incorporation into the MATLAB is provided. The component models are constructed by user-define functions provided in the simulation program. This modeling work is mainly employed to analyse the characteristics of swi...

Dynamic hysteresis modeling and its application in numerical field analysis are challenging tasks. This paper presents a measurement system to realize and to measure frequency-dependent behavior of ferromagnetic hysteresis. The well-known static Preisach model of hysteresis has been extended to simulate the dynamic behavior. The full paper will present the model in detail as well as its applica...

Modeling processes are the activities of capturing and representing processes and control of their dynamic behavior. Desired features of the model include capture of relevant aspects of a real phenomenon, understandability, and completeness of static and dynamic specifications. This paper proposes a diagrammatic language for engineering process modeling that provides an integration tool for cap...

This paper presents equivalent models of Modular Marx Multilevel Converter Diode (MCD) plus load, for bipolar or unipolar operation. With these models, it’s possible to analyze and understand the dynamic behavior of the pulse output voltage and current at the load. Simulation and experimental results, for different voltage levels, and various types of load are presented. Keywords-Modeling , Mul...

This paper describes a system-level SoC energy consumption estimation method based on a dynamic behavior of embedded software in the early stages of the SoC development. A major problem of SOC development is development rework caused by unreliable energy consumption estimation at the early stages. The energy consumption of an SoC used in embedded systems is strongly affected by the dynamic beha...
