This paper addresses the need of continued education of process industry practitioners such as operators and instrumentation engineers. The process industry regulatory control tuning situation of today is reviewed. Areas of potential improvement are identified. A course, aimed at fulfilling these needs is presented. Especially, useful laboratory experiments are outlined. The suggested course was g
We consider a networked control system where a linear time-invariant (LTI) plant, subject to a stochastic disturbance, is controlled over a communication channel with colored noise and a signal-to-noise ratio (SNR) constraint. The controller is based on output feedback and consists of an encoder that measures the plant output and transmits over the channel, and a decoder that receives the channel
Managing the resources of a virtualized data-center is a key issue in cloud computing. Existing research mostly assumes that applications are either allocated the required resources or fail. Combined with the fact that most cloud applications have dynamic resource requirements, this imposes a fundamental limitation to cloud computing: To guarantee on-demand resource allocations, the data-center ne
The design of a controller for glycemia regulation, either in open or in closed-‐loop, relies on models able to describe the effects of a meal intake and an insulin injection on blood glucose dynamics. The purpose of this study was therefore to propose a physiological relevant yet parsimonious model for carbohydrate action on fasting blood glucose in T1DM patients when no insulin is taken.
As farms are getting bigger with more animals, less manual supervision and attention can be given the animals on both group and individual level. In order not to jeopardize animal welfare, automated supervision is in some way already in use. Function and control of ventilation is already in use in modern pig stables, e.g. by the use of sensors for temperature, relative humidity and malfunction con
This paper describes a knowledge integration framework for robotics, whose goal is to represent, store, adapt, and distribute knowledge across engineering platforms. The architecture abstracts the components as data sources, where data are available in the AutomationML data exchange format. AutomationML is an on-going standard initiative that aims at unifying data representation and APIs used by e
In this paper a distributed version of the Kalman filter is proposed. In particular, the estimation problem is reduced to the optimization of a cost function that depends on the system dynamics and the latest output measurements and state estimates which is distributed among the agents by means of dual decomposition. The techniques presented in the paper are applied to estimate the position of mob
An adaptive resource management system combined with a thermal controller is presented. The aim of the system is to dynamically allocate computing resources to applications competing for the same computing resources in such a way that the system is not overheated. The approach has been implemented on a mobile robot. Experimental results are presented showing the feasibility of the approach.
Cloud computing is an application hosting model providing the illusion of infinite computing power. However, even the largest datacenters have finite computing capacity, thus cloud infrastructures have experienced overload due to overbooking or transient failures. The topic of this paper is the comparison of different control strategies to mitigate overload for datacenters, that assume that the r
Turbines operating in wind farms are coupled by the wind flow. This coupling results in limited power production and increased fatigue loads on turbines operating in the wake of other turbines. To operate wind farms cost effectively, it is important to understand and address these effects. In this paper, we derive a stationary model for turbine interaction. The model has a simple intuitive structu
We aim to measure the effect of relationship building between target-firm and financial advisor in the Mergers and Acquisitions industry. We also aim to investigate what affects the target-firm’s decision to stay loyal or switch financial advisor. Our main findings show that relationship building does not have a significant effect on the advisor fee and speed of transaction. Instead of earlier c
This thesis examines the Technical and Vocational Education and Training(TVET) related contents (including legal instruments and other guidance) from human rights bodies,ILO and UNESCO these three international bodies and also from China this national context. It analyzes the related legal frameworks of TVET from those sources and assesses their impacts in the national level, finally concludes the
Denna studie undersöker hur syriska och ukrainska flyktingar är representerade i svensk media. Frågorna som ställs är hur medias representation av flyktingar 2015 och 2022 skiljer sig åt, och i vilken utsträckning de representeras som individer med mänskliga rättigheter. Studien använder sig av tryckta nyhetsartiklar publicerade av den svenska nyhetstidningen Aftonbladet under de två tidsperiodernThis study examines the ways Syrian and Ukrainian refugees are represented in Swedish media. The questions posed are how media’s representation of refugees in 2015 and 2022 differentiate, and to what extent they are represented as subjects of human rights. The study makes use of printed news articles published by the Swedish newspaper Aftonbladet during the two time periods. The theoretical framew
While some individuals experience romantic relationships as overwhelming and intense, others experience their relationship as more secure and stable. Previous research has shown that individual differences in attachment account for various characteristics of romantic relationships. The present study (N = 280) investigates why romantic relationships are experienced differently, proposing infatuatio
