To find a controller that provides the maximal stability margin to an LTI system under rank-one perturbations is a quasiconvex problem. In the paper, the dual quasiconvex problem is obtained, using the convex duality arguments in the Hardy space H∞. It is shown that the dual problem can be viewed as minimization of a "length" of uncertainties that destabilize the system. Several examples establish

We study here deterministic broadcasting in geometric radio networks (GRN) whose nodes have complete knowledge of the network. Nodes of a GRN are deployed in the Euclidean plane (R 2) and each of them can transmit within some range r assigned to it. We adopt model in which ranges of nodes are non-uniform and they are drawn from the predefined interval 0 ≤ r min ≤ r max . All our results are in the

With the recent expansions of the European Union, there are now 12 new member states that are implementing European policy. One of these policies, with implications for energy production and security, is the Common Agricultural Policy. This article will focus on the impact the Common Agricultural Policy can have on farmers in Poland who have been encouraged by calls to cultivate energy crops. In a

The main premise of Self-Service Business Analytics (SSBA) is to make business employees autonomous during the data analytical process. To empower business employees, organizations are decentralizing their analytical capabilities through an SSBA approach. Yet, little is known about how employees integrate resources, such as, among others, personal competencies, environment resources including tech

Among the major IT security challenges facing organizations is non-malicious employee behavior that nevertheless poses significant threats to an organization's IT security. Using a grounded theory methodology, this paper finds that organizational security behaviors are inherently related to employee assumptions regarding the importance of IT security policy compliance and regarding the reason why

The tourism sector has recommitted itself to be ‘climate neutral’ by 2050 through its 2021 Glasgow Declaration: A Commitment to a Decade of Tourism Climate Action. The declared ambition is consistent with the Paris Climate Agreement and net-zero emission targets; however, lacks specific actions by which such a transition might be achieved. The highly influential International Energy Agency (IEA) h

A closed-loop and an open-loop active vibration control technique are critically compared, accounting for the effects of finite precision arithmetic. The main result is that the relevance of such effects is pointed out and characterised, as rigorously as possible at the present state of the research, in a suitably idealised context, and with specifically devised indicators. Also, the differences b

Modern wind turbines are designed to withstand approximately for a lifetime of 20 years [1]. However, a very long design life of 100 years or more can be expected for high-quality concrete foundations. Thus there is a big difference in lifetime between wind turbines and foundations. There is a significant economic benefit of replacing the out-of-date wind turbine with a new turbine of better power

With roots in social psychology, second language (L2) motivation has largely been investigated using self-report techniques. Studies drawing on observational data gathered in contexts where learning takes place are rare, and understandings of how motivation evolves in classroom interactions remain limited (Boo, Dörnyei, & Ryan, 2015). In a position paper in Language Teaching, Ushioda (2016) ma

Why is theorizing important? What does it do? This note reflects on the broad question of what we do when we theorize, taking its starting point from the Greek notion of theoria. The argument is that theorizing as an uncertain journey, i.e. as a form of travelling along a path towards the unknown or unfamiliar, has unjustly fallen into disrepute. The notion of ‘theory’ is today primarily associate

This paper deals with the estimation of the design force in self-tapping screws used as a reinforcement ofnotched cross laminated timber plates (CLT). With the reinforcement, apart from an increased load-carrying capacity, amore ductile behaviour of this detail can be achieved. An analytical model based on the Timoshenko Beam Theory wasdeveloped, enabling the estimation of the axial force in the r

This project focus on mouthfeel and textures within food area and try to connect it with emotion. The concept is inspired from space and Mars exploration in food related topics. Developing with experiments and coming up with a set of emotions outlet tools for not only eating but exploring your mouth. There are tons of product in markets that focus on only getting food from plate to mouth. However,

Musikbranchen och högre musikutbildningar är ojämställda i förhållande till kön. Syftet med denna undersökning är att ta reda på hur musiklärare kan jobba för att ge pojkar och flickor samma möjligheter att utvecklas musikaliskt. Metoden som använts är kvalitativ forskningsintervju. Intervjuerna visade att om instrumentfördelningen ska bli jämställd ur ett könsperspektiv behöver en som lärare styrThe music business and higher music educations are uneven in relation to gender. The purpose with this study is to find out how music teachers can work to create an education where all students have the same opportunities to learn and evolve. The method used is qualitative research interview. The interviews showed that if the instrument distribution in a class is to be equal by gender, the teacher

Detta examensarbete är en utvärdering av möjligheter och projektrisker i ett samarbete inlett mellan E.ON Sverige AB, ABB AB och Telefonaktiebolaget L M Ericsson. Syftet med det branschöverskridande samarbetet är att utveckla smarta energilösningar och det har även inlett ett pilotprojekt inom området kommersiella fastigheter. Examensarbetets syfte var att analysera och bedöma hur möjligheter och

The Brussels Agreement signed on April 19th 2013 has been described as a historical deal on the normalization of relations between Kosovo and Serbia. The agreement relates to questions of how to integrate the Kosovo Serb minority in Kosovo. The answer is decentralization. However are the intentions of decentralization to truly integrate the Kosovo Serb? And why has the agreement received so much r

Under mina år som fagottist så har jag de senaste fyra fem åren brottats med smärtor i framför allt min vänstra arm och axel. Skadorna uppstod av dålig hållning och spändhet som i sin tur ledde till överbelastning utav muskler. Vad finns det för metoder för att få bukt på smärtproblematik för mig som fagottist? Det här är den beskrivande delen av mitt examensarbete som handlar om hur jag under min

According to researches, China is aging faster than any other country in history. Meanwhile, China has been a country with a close-family-ties-tradition for over thousand years. However, as the family structures are getting smaller, people’s lifestyle is also changing over time. Nowadays, the word ‘a distance of a bowl of soup’ is quite popular in between all generations. It represents an ideal wa
