This paper approaches the uncertainty problem from the point of view of adaptive control. The uncertainty is reduced by continuous monitoring of the response of the system to the control actions and appropriate modifications of the control law. It is shown that this approach makes it possible to deal with uncertainties that cannot be handled by high gain robust feedback control.
This paper presents a solution to the saturation problem in cascade control schemes. When cascade control approaches work in linear mode without saturation influence, important improvements can be achieved in industrial control loops. The effect of disturbances and/or nonlinear actuator behaviours on the main process variables can be considerably reduced. However, when saturation arises in the inn
This article offers an actionable framework for dealing with trust violations in R&D partnerships: it explains how to turn around a conflicted R&D partnership, repair trust, and learn from the experience. As innovation becomes more open, firms increasingly find themselves involved in R&D collaborations with suppliers, customers or even competitors. Trust plays a fundamental role in suc
In the Multiagent Connected Path Planning problem (MCPP), a team of agents moving in a graph-represented environment must plan a set of start-goal joint paths which ensures global connectivity at each time step, under some communication model. The decision version of this problem asking for the existence of a plan that can be executed in at most a given number of steps is claimed to be NP-complete
This article expands current acquisition literature to include sociocultural challenges on inter-organizational levels following acquisitions of young, innovative firms. Socioculture here denotes network parties' shared values, belief systems, and practices. Three acquisitions illustrate their consequences. The young, innovative firms and their acquirers are part of different networks, have dissim
The purpose of this thesis is to explore food safety risk perceptions of students at Peking University and to what extent they influence their food consumption behaviour. Apart from existing research about food safety and consumer behaviour, the study relied on findings from thirteen interviews and participant observation. Since much of food safety involves risks, Ulrich Beck’s risk society theory
Objectives The overall aim of this study was to aggregate the conclusions of all investigations conducted after suicides reported to the supervisory authority in Sweden in 2015, and to identify deficiencies in healthcare found in these investigations; the actions proposed to deal with the deficiencies; the level of the organisational hierarchy (micro-meso-macro) in which the deficiencies and actio
With the rapid development of Digital Rights Management (DRM), Technological Protection Measures (TPM) and Rights Management Information (RMI) as components of DRM have become essential tools for safeguarding copyright. The WIPO Copyright Treaty (WCT) and the WIPO Performances and Phonograms Treaty (WPPT) were the first international agreements to establish protections for TPM and RMI. Subsequentl
This paper provides insights into the handling of climate change issues related to cultural heritage at different government decision levels dealing with physical planning, and in particular roads. Data are derived from a qualitative analysis of official reports and interviews with local and regional planners in three Swedish regions with contrasting climates. The theoretical lens of Institutional
Many people use conspiracy theories to make sense of a changing world and its ever more complexif social structures (e.g., international financial systems, global bodies of governance), tragic events (e.g., terrorist attacks, man-made catastrophes, or natural disasters), or socio-political and economic issues (e.g., security, migration, distribution of resources, health care). The widespread flour
Uncertainty touches most aspects of life and cannot be avoided, anybody is frequently presented with situations wherein a decision must be made when he/she is uncertain of exactly how to proceed. Narrow down into Information Systems (IS) field, uncertainty could be regarded as a basic but difficult problem that every HCI designer need to deal with within their design process. The purpose of this t
