in this research, the applicability of geographic information system (gis) and remote sensing (rs) techniques was tested to assess soil erosion risk with the icona erosion model. this study was carried out in the tange bostanak area because of its variety of diverse landforms, land uses and land covers. the erosion risk assessment phase of this model consists of seven steps that mainly use slop...

A tape transport system consisting of a take-up reel servo, a supply-reel servo, and a capstan servo is proposed. The mathematical model of the system is derived. Two well know controllers – Linear Quadratic Regulator (LQR) and P/PI controller, are designed to regulate the output of the system. An input gain matrix N is calculated and applied to the LQR to eliminate steady-state offset. Simulat...

In this paper, we develop a dynamic lumped parameter model of a pneumatic membrane actuator to inform the design of a shape display that meets force, speed and spatial density specifications for refreshable braille. A system identification experiment is undertaken to determine relevant system parameters that remain fixed under variation of the lengths of the connecting tubes and cavity volumes....

A distortion analysis based on the large signal behavior of the basic switched-current memory cell is presented. In the first part, based on a closed form solution of the step response, distortion due to the settling error is addressed. In the second part, distortion caused by clockfeedthrough is analysed. The solutions are compared with simulated and/or measured results. Furthermore, harmonic ...

This paper presents a simple identification algorithm for linear models. The main motivation behind this algorithm is to familiarize students and engineers having limited mathematical knowledge with the principles of system identification without adding more mathematical burdens. This is achieved by using the principles of the step response coefficients and its explicit relation with the system...

a r t i c l e i n f o Keywords: Dimensional metrology Interoperability Standard development STEP DMIS Dimensional metrology is an important part of any manufacturing system. It consists of distinct components and requires a large, diverse, and interconnected knowledge base. How to pass information seamlessly with minimal cost and minimal data loss between different components of a dimensional m...

In this paper, a new approach is proposed to model and control the temperature of a thermal barrel of a plastic molding machine. Usually the thermal barrel behavior is expressed in terms of a parameterized linear model to be used in control strategies design. We establish a new model based on the structure of a Takagi-Sugeno fuzzy system, and utilize the clustering method to generate the rule b...

In many multiagent domains, no single observation event is sufficient to determine that the behavior of individuals is suspicious. Instead, suspiciousness must be inferred from a combination of multiple events, where events refer to the individual’s interactions with other individuals. Hence, a detection system must employ a detector that combines evidence frommultiple events, in contrast to mo...

Precise trajectory tracking is a crucial property for Micro Air Vehicles (MAVs) to operate in cluttered environment or under disturbances. In this paper we present a detailed comparison between two state-of-the-art model-based control techniques for MAV trajectory tracking. A classical Linear Model Predictive Controller (LMPC) is presented and compared against a more advanced Nonlinear Model Pr...
