This paper presents a hybrid procedure to solve Model Predictive Controller (MPC) for Piecewise Affine System (PWA) The approach presented here belong to the class of Branch and Bound (B&B) methods. The procedure uses the concepts of reachable set combined to the specific B&Bmethods, in order to reduce the number of Quadratic Problems (QP) needed to be solved by t he optimization algorithm.

One of the airborne pollutants in wood products industry is formaldehyde, which may pose some health effects. Therefore this study is conducted to determine formaldehyde levels in 100 furniture-manufacturing workshops in Ankara and also to determine the symptoms, which may be related with formaldehyde exposure among the workers. Indoor formaldehyde levels ranged from 0.02 ppm to 2.22 ppm with a...

This paper tests a set of hypotheses relating to agency and Schumpeterian views on how competition affects performance. A survey data set of Australian workplaces is used, with the change in labour productivity growth as the dependent variable. The results show strong support for the idea that intense competition raises productivity growth in managerial workplaces, but not in non-managerial wor...

Background: The objective of the study was the evaluation of the infection of ticks with pathogenic microorganisms at various workplaces (timber acquisition, forest growing, forest cultivation, forest protection). Material and Methods: Eight hundred sixty one Ixodes ricinus ticks collected from 4 workplaces were examined for the presence of Borrelia burgdorferi, Anaplasma phagocytophilum and Ba...

Small workplaces have particular injury risks and are enduringly difficult for the occupational health and safety (OHS) system to reach. This paper puts forward an "upstream" perspective on OHS in small workplaces that moves beyond the attributes of the workplace and those who work there. The paper draws on and synthesizes ideas and findings from emerging upstream OHS research, our own empirica...

The aims of this study were to investigate the concentrations and characteristics of nanoparticle exposure at various workplaces. We compared the concentration and characteristics of nanoparticles at nine workplaces of three types; i.e., small laboratories (LAB), large-scale engineered nanoparticle manufacturing workplaces (ENP), and unintended nanoparticle-emitting workplaces (UNP), using real...
