xn 1⁄4 Aþ xn22 xn21 p ; n 1⁄4 0; 1; . . .; with p, A [ (0, 1), p – 1 and x22, x21 [ (0, 1). It is shown that: (a) all solutions converge to the unique equilibrium, x 1⁄4 Aþ 1, whenever p # min{1, (A þ 1)/2}; (b) all solutions converge to period two solutions whenever (A þ 1)/2 , p , 1; and (c) there exist unbounded solutions whenever p . 1. These results complement those for the case p 1⁄4 1 in...

water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater. cyanide is one of the toxic materials which can be found in some industrial wastewaters. strict laws set by international bodies have forced industries to work on developing efficient cyanide remo...

The industrial cluster concept has become a subject of intense research studies and economic analysis starting with the study conducted by Michael E. Porter regarding the competitive advantage of nations. This concept is an economic phenomenon that is placed in a competitive context in which many businesses simultaneously compete and collaborate to gain different economic advantages. The econom...

Using data from the Workplace Industrial Relations Surveys of 1980, 1984, and 1990, the authors investigate processes of job creation and job destruction in Britain. They find that rates of employment growth, job creation, and job destruction were higher at the end of the 1980s than at the beginning. Bothjob creation and job destruction were extremely concentrated: about 50% of each was account...

Dynamic approaches to a management system of the present industrial practice, forcing businesses to address management issues in-house continuous improvement of production and non-production processes. Experience has repeatedly demonstrated the need for a system approach not only in analysis but also in the planning and actual implementation of these processes. Therefore, the contribution is fo...

One robust result from many small-scale experiments has been that plant community productivity often increases with increasing plant diversity. Most frequently, resource-based or competitive interactions are thought to drive this positive diversity-productivity relationship. Here, we ask whether suppression of plant productivity by soil fungal pathogens might also drive a positive diversity-pro...

Obviously, numerous famous brands come from industrial clusters, which become the main motive force to promote regional development. It indicates that the industrial cluster environment can promote brand development. This paper will study industrial clusters from the brand perspective, through reviewing the classification of industrial clusters, put forward the new classification of industrial ...

This paper discusses a new experimental robot load identification method that is used in industry. The method is based on periodic robot excitation and the maximum likelihood estimation of the parameters, techniques adopted from [1]. This method provides (1) accurate estimates of the robot load inertial parameters, and (2) accurate actuator torques predictions, both of which are essential for t...
