A Magnetic Circuit Approach to the Prediction of Variable-Reluctance Step Motor Static Characteristics
… has been a need to accurately predict their static characteristics based on motor geometry and material properties. In this work, the magnetic circuit method is applied to find the field distribution within a high-resolution variable-reluctance step motor. The method is generalized to include …

Evaluation of the dynamic characteristics of the K-Gill anemometer
The dynamic characteristics of the K-Gill anemometer were evaluated by comparing the anemometer with a hot wire system in a field test, after the static characteristics of the anemometer had been evaluated in a wind tunnel test. The wind tunnel test showed a non-linear and a non-cosine behavior, as …

Evaluation of the VPI & SU fluid film bearing test rig
… evaluations of fluid-film bearings for static characteristics and the corresponding NPADVT analysis are presented. With the code thus anchored, and its limits established, experimental data generated with the test rig are compared to appropriate analyses and the test rig shown to be …

Finite Element Method Modeling Of Advanced Electronic Devices
… device for future nano-scale system. Non-quasi-static effects in AC characteristics of carbon nanotube field-effect transistors are examined by solving a full time-dependent, open-boundary Schrödinger equation. The non-quasi-static characteristics, such as the finite channel charging time, …

Multimodal Recognition of Social Behaviors and Personality Traits in Small Group Interaction
… played by the participants in a meeting, to static characteristics of individuals (per-sonality traits) and behavioural outcomes (task performance).

Static and Dynamic Characterization of Silicon Carbide and Gallium Nitride Power Semiconductors
… are made with these wide-bandgap materials. The static and dynamic characterization of six different SiC MOSFETs from different manufacturers are presented. The static characterization consists of the output characteristics, transfer characteristics and device capacitances. High temperature (up …

Day centres for the elderly: the architectural setting and user requirements
… and/or disabled over time and the comparatively static characteristics of architectural setting designed to accommodate independent old people. The aim of this research was to study this problem area in detail. This involved a broad examination of the characteristics of the elderly population and …

Simulation of household in-home and transportation energy use : an integrated behavioral model for estimating energy consumption at the neighborhood scale
… and directly correlate consumption with static characteristics without explicit behavioral links. In this thesis I aim to provide a comprehensive method for understanding household energy behavior over time. Using household survey data and neighborhood form characteristics from Jinan, a …

Passive vibration isolators with high-static-low-dynamic-stiffness
… a vibration isolation mount would have a high static stiffness to prevent too large a static displacement to occur, but a low dynamic stiffness which reduces the natural frequency and extends the frequency range of isolation. For linear mounts these two features are mutually exclusive. However, …

A structured approach to identification techniques for the analysis of industrial processes
… model structures composed from nonlinear static and linear dynamic characteristics. The scheme is simple in use and intuitive to understand and follow. Therefore, it can be directly applied also by inexperienced engineers, who look for quick and efficient solutions as a basis even for …

Sliding Mode Controller Design for ABS System
… brakes is proposed to describe their static characteristics (angular speed versus brake torque). The performance of the new mathematical model is better than the other three models available in the literature in a least-square sense. Compared with old models that treat reluctance as a …

Analysis of a permanent magnet hybrid linear stepping motor
… and disadvantages of these two methods. The static characteristics show that the FEM demonstrates a better correlation with the experimental results than the RNA. The reason is that some assumptions have been made in order to obtain a simplified model in the RNA. The RNA, in general, tends to …

Remote Sensing-based Channel Modeling and Deployment Planning for Low-power Wireless Networks
… where to place the wireless nodes. The characteristics of the environment, both static (e.g., obstacles obstructing the link line of sight) and dynamic (e.g., changes in weather conditions) cause variability in the communication performance, thus affecting the network operation quality …
