The traditional neoclassical model of economic growth, first developed by Solow (1956) and Swan (1956), who independently proposed similar one-sector models, provides a theoretical framework for understanding world-wide growth of output and the ...

A closed cycle of a mass consumption and a renewal of some product is investigated. For this aim a closed queueing network with a number of customers, a number of servers in a consumption node and service intensities proportional to a large parameter n ...

In some industrial systems like petrochemicals, the same raw materials are used in producing several products. However, most of the classical production inventory systems treat the economic order quantities (EOQ) of raw materials, which are used in ...

I will present the most important theories of fracture mechanics and their evolution in time. This evolution will be described from an historical point of view following three major directions: experimental methods, numerical methods and analytical ...

Nanotechnology Patents are concentrated in the industrial leader countries leading to a Nanodivide that will increase Regional Underdevelopment and will maintain a scarce demand of new products. Societal effects need to be taken on account to ensure the ...

In this paper we are interested in studying the asymptotic behavior of the energy associated to the following nonlinear homogeneous system of hyperbolic partial differential equations: { u″ + Au - Δu′ + (|v|^ρ+2 + |w|^ρ+2)|u|^ρu = 0 v″ + Av - Δv′ + (|u|^ρ+2 ...

As one of the hot issues of studying in the field of modern traffic engineering, the license plate recognition (LPR) has attracted more and more attention. In this paper, an experimental system for the LRP of China-style license plates is presented. The ...

The paper describes creep tests of the small specimen, and analyses the properties of cement pastes. Material properties were tested in compression tests. Creep of cement pastes was tested on the cylindrical specimens with diameter 10mm. Tests were ...

Material properties of cement pastes are used like a input parameters for the simulation of the creep cement pastes. For determination of properties of the cement pastes is the necessary the specimens testing in compression. From compression test is ...

A Particle Swarm Optimization (PSO) algorithm is examined to solve the inverse problem in structural health monitoring. The damage detection problem is formulated as a PSO problem to find a damaged stiffness matrix that satisfies the structure's ...

Friction influence on the control law of a inverted pendulum is analyzed. Assuming a dry friction characteristic as piecewise linear function described by four parameters a graph for verifying friction influence on the control law is proposed.

A method for identifying parameters of a linear mechanical system is proposed. The method is based on ERA/OKID identification method developed by Juang [1]. This procedure has been tested on a light-damped mechanical linear apparatus.
