Specifying and Synthesizing Energy-Efficient Production System Controllers that Exploit Braking Energy Recuperation

Reducing the energy consumption is a major concern in industrial production systems. One approach is recuperating the braking energy of robot axes. Ideally, their acceleration and deceleration phases should be synchronized so that the braking energy of one axis can be reused directly to accelerate another. This requires a detailed alignment of the axes' trajectories, but also a careful design of the overall discrete control. Finding an optimal control strategy manually, however, is difficult, as also many functional and safety requirements must be considered. We therefore propose an automated methodology that consists of three parts: (1) A scenario-based language to flexibly specify the discrete production system behavior, (2) an automated procedure to synthesize optimal control strategies from such specifications, including PLC code generation, and (3) a procedure for the detailed trajectory optimization. We describe the methodology, focusing on parts (1) and (2) in this paper, and present tool support and evaluation results

Social work with airports passengers

Social work at the airport is in to offer to passengers social services. The main methodological position is that people are under stress, which characterized by a particular set of characteristics in appearance and behavior. In such circumstances passenger attracts in his actions some attention. Only person whom he trusts can help him with the documents or psychologically

IFPOC Symposium:Discovering antecedents and consequences of complex change recipients' reactions to organizational change.

IFPOC symposium: Discovering antecedents and consequences of complex change recipients' reactions to organizational change Chairs: Maria Vakola (Athens University of Economics and Business) & Karen Van Dam (Open University) Discussant: Mel Fugate (American University, Washington, D.C) State of the art Organisations are required to continuously change and develop but there is a high failure rate associated with change implementation success. In the past two decades, change researchers have started to investigate change recipients' reactions to change recognizing the crucial role of these reactions for successful change. This symposium aims at identifying and discussing the complex processes that underlie the relationships among antecedents, reactions and outcomes associated with organizational change. New perspective / contributions This symposium consists of five studies that extend our knowledge in the field by (i) providing an analysis of change recipients' reactions going beyond the dichotomous approaches (acceptance or resistance) (ii) revealing understudied antecedents-reactions and reactions-consequences patterns and relationships (iii) shedding light on the role of contextual factors i.e team climate and individual factors i.e emotion regulation on the adaptation to change. This symposium is based on a combination of both quantitative (i.e diary, survey) and qualitative (i.e interviews) research methodology. Research / practical implications This symposium aims to increase our understanding of the complex processes associated with change recipients' reactions to change. Discovering how these reactions are created and what are their results may reveal important contingencies that can explain how positive organizational outcomes during times of change can be stimulated which is beneficial for both researchers and practitioners

Qigong at Work: Where East Meets West

State of the Art Qigong is part of Traditional Chinese Medicine (TMC) and aims to balance body and mind. The roots of Qigong lie in China, where Confucian and Daoist scholars (500-400 B.C.) noted that one must learn to balance and relax one’s thoughts and emotions to avoid illness (Yang, 1997). In the Western world, Qigong is best known for its slow and coordinated movements. According to TCM, these movements will help regulate one’s ‘qi’, or life energy, through the body to improve the health and harmony of mind and body. During the practice of Qigong, one’s breathing, attention and movement are aligned. As such, Qigong is sometimes considered Mindfulness in movement (although there are many important differences). New perspectives / contributionsQigong has many positive outcomes on health and wellness. In both patient groups and healthy individuals, Qigong has been shown to improve psychological well-being, quality of life, immune function, balance and related risk-factors, and bone density (Jahnke et al., 2010). As such, Qigong offers a validated way to reduce the physical and mental activation that results from a person's work. While recent research has demonstrated how important it is to take short breaks at work, there is still little attention for Qigong exercises as a means to recover at work.Practical Implications In this presentation, we will explain and practice several Qigong exercises. These movements can be used at work (and at home) to recover from (hormonal) activation, ‘empty’ one’s head, and restore the body-mind balance. <br/
