Based on the introduction of the concepts of logistics and logistics center, this paper analyzed the status and problems of Jilin Province’s logistics center, and proposed the steps, principles and factors for site selection of logistics center. Then by listing and comparing nine kinds of logistics center site selection method, including Analytic Hierarchy Process, Cluster Algorithm, Genetic Al...

This article discusses the automatic control system for parameters (rotor speed and gas temperature) of a turbine engine based on clear logic controllers. It is proposed to use logical controllers, consisting comparing device, fuzzifier, an inference block with production rules given membership functions terms variables, defuzzifier. Precise using precise terms, in loops object’s influence stab...

A balance platform setup was defined for use in the determination of the center of gravity in the sagittal plane for a wheelchair and patient. Using the center of gravity information, measurements from the wheelchair and patient (weight, tire coefficients of friction), and various assumptions (constant speed, level-concrete surface, patient-wheelchair system is a rigid body), a method for estim...

according to development of displacement–performance based design, there are some studies on different structures which most of them are about regular plan structures. in this research has been tried to review the frame steel structures designed based on 2800 standard of iran to achieve the designed structures performance level to find how much function levels it covers in earth quake. to show ...

The Greenfield-Chiclana Collapsing Defuzzifier comes in many variants, depending on the order of slice collapse. The accuracy of the fundamental variants of forward, backward, inward and outward, and the composite variants of forward-backward and outward right-left is compared experimentally for the discretised interval type-2 fuzzy set. Keywords— Centroid, Collapsing, Defuzzification, Interval...

Newton’s second law as written appears simple, but how to use the law perceptually is a complex task. Most of the cases it is good for conceptual discussion or development. Normally the sign convention is not shown and has problems to solve. Due to this fact, many do not fully understand Newton’s second law. Modeling complex behavior is like the Newtonian law; people tend to misuse. In this art...
