The parameter extraction method of De Soto is implemented in the single diode model and evaluated against measured data at varying temperatures and irradiances. The simulated current-voltage-curves (IV-curves) of the method can be seen as acceptable at reference conditions, but they result in a different IV-curve, not matching the measured IV-curve, at conditions that differ from the reference conditions...
The European Electronic Toll Service (EETS) allows different possibilities for the overall system design of interoperable toll systems. We study the effect of the overall system design on the operational costs using a model based, holistic, executable specification. The model is set up to give an accurate description of the interdependences as seen in the German toll system. Two different scenarios...
The objectives of this studies were to develop the optimum shoot and ramification number dynamic models for rapeseed (OSRNDMR), and to lay an foundation for Rapeseed Cultivation Simulation - Optimization - Decision Making System (Rape - CSODS), which can design its planting, regulate and control its growth and development, and fulfill its high yield, good quality, high benefits and standard production...
New driver assistance systems can have consequential effects on traffic flow. Investigative simulations are necessary for the design, optimization and evaluation of these assistance systems. Previous calibration and validation methods utilized either microscopic or macroscopic measurement data.This paper's purpose is to argue that the formerly held calibration and validation perspectives with regard...
Aiming at structure optimization and manufacturing process planning problem of modern manufacturing equipment in designing process, we use Open Inventor and level of detail (LOD) technology to construct and optimize the simulation scene of equipment, besides we put forward a kind of virtual language (V-Code) based on virtual reality, which can plan the manufacturing process of equipment, and virtual...
The design principles of clinical PET data acquisition protocols require images of high statistical quality, while the scanning time remains relatively short and the total amount of radioactive dose does not exceed a level, above which significant count losses are observed. This can be satisfied by determining a range of injected dose levels where the performance parameter of noise equivalent count...
This paper presents a combined contactless energy and data transmission system, which is able to detect and to identify a secondary device and which is also able to check its absolute position during the energy transfer. Such an identification is needed in many fields of application under aspects like safety and security. Compared to conventional industrial communication systems like Bluetooth or...
Data communication is deeply studied to solve the real-time property and the stability of the data communication that is the key problem in the battle damage simulation system, following the logic process of data generating, sending, transmitting, receiving. Meanwhile, a series of optimized methods are proposed from the aspects of communication interface, communication server working model, concurrent...
Current mode (CM) scheme provides suitable alternative for the high speed on-chip interconnect signaling. This paper presents a energy-delay optimization methodology for the current-mode (CM) signaling scheme. Optimization for the CM circuits for on-chip interconnects requires a joint optimization of driver and receiver device sizes, as their parameters which affect the energy-delay performance depend...
Three applications in wireless networks where model-free stochastic learning is applicable, are discussed. The learning based optimization problems are formulated and simulation results are presented. Some open issues are also discussed.
We present a simulation study of the global count-rate performance of a positron emission tomography (PET) scanner with different levels of partial collimation to maximize the noise equivalent count rate for whole-body PET imaging. We achieve partial collimation by removing different numbers of septal rings from the standard 2-D septa set for the GE Advance PET scanner. System behavior is studied...
