Even though the agent-based simulation modelling has become a standard tool in transport research, current implementations still treat travellers as passive data structures, updated synchronously at infrequent, predefined points in time, thus failing to cover within-the-day decision making and negotiation necessary for cooperative behaviour in a dynamic transport system. Leveraging the fully agent-based...
The paper presents the designing process of the passive micromixer. Design parameters of microfluidic channel's geometry are optimized based on flow simulation results. CAD software Solid Works and application Flo Xpress are used for designing and simulation. Aim of presented student's work is not connected to any actual research activities. However part of MSc Thesis shows outcome of student's ability...
Lab-on-chips (LOCs) are small systems, which integrate, in the same device, several functions involving chemical analysis with bio-processing functionalities typically performed in a laboratory. As a consequence, it is a multi-domain system that can be described and designed with VHDL-AMS, a hardware description language that natively supports electronics, thermics and fluidics. On the other hand,...
The knowledge of the mathematical models of ocean currents and of power coefficients is necessary for a complete marine current generator systems modeling. Review of these models is the topic of this paper. For any of the listed marine current mathematical models, simulation results of marine current velocity as a function of time is presented. Also, using the mathematical model of ocean currents...
Cargo transportation is one of the most important topics in today's fast growing and globalized logistics sector. Ecommerce activities make valuable contributions to cargo and logistics sectors. In this study, technological transfer center of a cargo company in Turkey that consists of infeeds, outfeeds, reject line and a sorter system was considered. The main problem is the imbalance between the expected...
Two German High Performace Computing (HPC) centers (SCC & HLRS), as well as the Center for Interdisciplinary Risk and Innovation Studies (ZIRIUS) of the University of Stuttgart have jointly created a program to relay knowledge about simulations to students at secondary schools. Through this program they want to narrow the gap between visibility and significance of this technology in modern...
To study scientific application different computing paradigm used. Simulation of tool base Grid infrastructure plays its roll for study of grid base computation. We introduce the here Grid computing paradigm for resource coordination over the global computation world. Resources management and scheduling of applications in such large-scale distributed systems is a complex undertaking in case of Grid...
In this paper the modeling of the human granulopoiesis is investigated. This modeling is an important part of the further development of a decision support system to assist medical doctors in the treatment of irradiation injuries. Referring to an existing model of Fliedner and Steinbach we derive a new nonlinear time delay model of the human granulopoiesis with state dependent delays. Simulations...
A novel simulation modelling technique that may be used to reconstruct or predict longer-term water level dynamics of lakes and reservoirs has been elaborated. On the grounds of the conservation law and a kind of self-regulation property of these lakes, by using Kalman filters for the unmeasurable part of hydrologic-cycle dynamical path and output observation equation in traditional and in fuzzy-relational...
In fluorescence microscopy, where the benchmark datasets for validating the various image analysis methods are difficult to obtain, a great demand is either for manually annotated real image data or for realistic computer generated ones. In the last two decades, the latter case has become more and more accessible due to an increasing computer capabilities. However, the development of elaborate models,...
Time-derivative Cellular Neural Networks (TDCNN) is a general class of CNN having derivative connections between cells. It has been reported that several mixed-domain 3D spatiotemporal transfer functions for linear filtering can be implemented via TDCNN such as bandpass filters and visual receptive field models. In this paper a new computer simulation method for TDCNN is presented. The new simulation...
Image segmentation is a widely used in medical imaging applications by detecting anatomical structures and regions of interest. This paper concerns a survey of numerous segmentation model used in biomedical field. We organized segmentation techniques by four approaches, namely, thresholding, edge-based, region-based and snake. These techniques have been compared with simulation results and demonstrated...
A new direct synthesis method for tuning the Pseudo-Derivative Feedback controller for integrating as well as stable or unstable first order processes with time delay is presented. The proposed control structure and tuning method ensure smooth closed-loop response to set-point changes, fast regulatory control and sufficient robustness against parametric uncertainty. Simulation results show that the...
In recent years, the number of passengers visiting the major international airport, Taiwan Taoyuan International Airport (TPE), has increased dramatically. The passenger traffic has gone beyond the capacity of the airport as it was constructed for. One important infrastructure in the airport is the baggage handling system which consists of a set of conveyors that transport checked baggage to the baggage...
This paper proposes a memristor SPICE model using tukey window (or tapered cosine window) function. Compared with the proposed tukey window function and the previously boundary function, the proposed method is resistant to numerical errors. From the SPICE simulation result of relaxation oscillator, we find that the proposed model can be reduced the effect of round-off errors.
A recent study identified six mutations (three gain-of-function and three loss-of-function mutations) in the KCNA5 channel (encoding for the ultra-rapid delayed rectifier potassium current, IKur) associated with lone-atrial-fibrillation. However, the impact of the mutations on atrial electro-mechanical functions is unclear. In this study, we developed a coupled electro-mechanical model of the human...
In this simulation, the cardiovascular model was developed base on the physiological study. The parameter identification and validation was done with physiological data using Matlab/Simulink. This study has adopted the principle differential equation using analog-lump parameter model. The wave forms such as pressure, volume and flow in cardiovascular system were simulated. The simulation of cardiovascular...
Renewable resources importance has been highlighted for energy system sustainability and environmental protection since last 15 to 20 years. But their integration into electric power system is a challenging task due to their intermittent nature. Power system with renewables required simulation at small time scale to increase the confidence level and prepare a convincing plan. Work has been done to...
