SAE TEACHING USING SIMULATIONS

The increasing interest in applying small area estimation methods urges the needs for training in small area estimation. To better understand the behaviour of small area estimators in practice, simulations are a feasible way for evaluating and teaching properties of the estimators of interest. By designing such simulation studies, students gain a deeper understanding of small area estimation methods. Thus, we encourage to use appropriate simulations as an additional interactive tool in teaching

PERFORMANCE ASSESSMENT OF AIR CONDITIONING INSTALLATION IN MULTIFUNCTIONAL SPORTS HALL USING CFD SIMULATIONS

The purpose of the paper was testing of the air distribution system performance in the multifunctional hall. The numerical simulations of the airflows were made with the Ansys software. Three cases with two working modes of the installation were simulated: a large sport event with audience on the stalls, an exhibition with presentation boxes and an indoor ice rink. Direct results of the simulations and statistical data were analyzed. The results showed that for the ice rink and exhibition the

For this purpose, the cut-out part of the window profile was placed inside the insulated framework mounted inside the real window opening (Fig. 2). To monitor the temperature, seven T-type thermocouples connected to a data recorder were placed inside and on the surface of the profile, in half of its length (Fig. 3). Two more thermocouples were used to monitor internal and

Separating Signals with Specific Temporal Structure

Blind signal extraction is particularly attractive to solve signal mixture problems while only one or a few source signals are desired. Many desired biomedical signals exhibit distinct periods. A sequential method based on second order statistics is introduced in this paper. One can choose to recover one source signal or all signals in a specific order. The validity and performance of the proposed method are confirmed by computer simulations.

An Enhanced Scheme in Controlling Both Coverage and Quality of Service in Wireless Sensor Networks

maintain QoS without knowing the total number of sensors. However, the Gur Game-based scheme does not consider the active sensor coverage. The problems of collecting redundant data and wasting bandwidth and battery energy arise if active sensors are distributed too densely or too sparsely. Therefore, this study proposes a Coverage-Aware QoS Control (CAQC) to achieve both QoS and coverage control using an enhanced reward function. Simulations that compared our scheme with previous studies in various

A MULTI-SCHEME ADAPTIVE ROUTING ALGORTHM BASED ON SPRAY AND WAIT FOR DALAY TOLERANT NETWORKS

, we propose an improved Adaptive Spray and Wait scheme, named ASW, for different delay tolerant network scenes. In this paper, we define a hybrid utility metric combined with multiple variables, delivery probability and similarity. Then, we distribute message copies in accordance with the proportion of the utility value to optimize the delivery ratio. Extensive simulations have been conducted to verify the efficiency of our proposed algorithm. In addition to the comparison, the results also show

Used the reliable relationships, social popularity is proposed to evaluate the social power of node in the network. SPBR makes the routing decisions based on the popularity, leading message closer to destinations with low hops of routing and network resources. Extensive simulations are conducted and the results

MODELLING THE SHOCK ABSORBER PISTON VALVE USING 2-WAY FLUID-STRUCTURE INTERACTION

based on the actual valve geometry used in the shock absorber design. As a result, the described approach is intended for use in industrial applications in development works, in particular, at the conceptual stage. To prove the reliability of the model, two valve compositions are chosen to be measured on a test bench and modelled in FSI simulations. For both of them, a satisfactory level of correlation is achieved, with the correlation error below 10% and well-predicted valve opening points. As a

Using a systematic approach in designing the optimal fuzzy structure based on the ICA is our contribution here which leads to better performance of PMSM. Comparing the results of simulations, done in Matlab Simulink, between the suggested control strategy and performance of the PID, expresses the remarkable capability of FPID in overcoming the complexity of control of the nonlinear and uncertain systems.

On the basis of the conducted tests, it was found that it is worth considering the replacement of collision tests of the whole vehicle by tests of its individual components. This can be considered a new approach that is not widely used. Currently, most often, crash tests of entire vehicles are conducted (high costs) or computer simulations are performed (often with unsatisfactory accuracy).

Social-cognition and dog-human interactions: Is there potential for therapeutic-interventions for the disability sector?

investigated the relationship between dogs and children with socio-communicative developmental delays. It emerged that both fields of research suggested that through “embodied simulations”, humans can learn to attune to others, and generate a representation of behaviours of others (Gallese, 2005; Solomon, 2012). When translated to individuals with socio-communicative delays, perhaps an alternative approach (e.g. to language and vision) to acquiring knowledge concerning the world of social interactions

APPLICATION OF THE HOMOTOPY ANALYSIS METHOD FOR DETERMINING THE FREE VIBRATIONS OF BEAM

homotopy analysis method with the approximate solutions determined numerically by applying the Mathematica software. Differences between the obtained solutions were slight. However, the advantage of the examined method is that we receive here the approximate solution in the form of continuous function which can be used then in a further analysis or to perform various simulations. Whereas when we apply the numerical methods, we get the discrete set of values which may be potentially used later for

Large unbalanced vibrations were found, affecting not only the fatigue resistance of the locomotive, but also influencing the crew and passengers in the train consist. Developed model and simulations were used to check several possible parameter variations of the locomotive, but the problems were found to be in the original design such that no serious improvements can be done in the space available for the running gear and therefore the

This paper shows that the system proposed is a feasible method to investigate user behaviours of mobile data usage. If the sample size of users involved could be increased in the future, it would be possible to develop a model for real-time simulations of mobile users in specific areas so that limited connection resources could be dynamically

For this purpose, a partially integer linear optimization model has been created in Matlab, which provides a valid plan with the shortest waiting times for all vehicles. Simulations have been made for different numbers of ramps and vehicles. The results show that the model is suitable for pre-creating a valid plan for the
