The Furuta pendulum is used to evaluate a friction compensator based on the dynamic LuGre friction model. The effect of friction compensation is very well illustrated by reduction of limit cycles when stabilising the pendulum. The observer based LuGre friction compensator is compared with classical Coulomb and Stiction compensator schemes. Existing analysis of the LuGre observer is extended to obs
This Letter presents a search for a heavy neutral particle decaying into an opposite-sign different-flavor dilepton pair, e(+/-) mu(-/+), e(+/-) tau(-/+), or mu(+/-) tau(-/+) using 20.3 fb(-1) of pp collision data at root s = 8 TeV collected by the ATLAS detector at the LHC. The numbers of observed candidate events are compatible with the standard model expectations. Limits are set on the cross se
The relationship between bolus volume (2.5, 5, 10 and 20 ml) and larynx elevation during swallowing was assessed in 10 non-dysphagic and 10 dysphagic individuals without pharyngeal dysfunction. Laryngeal elevation in different types of pharyngeal dysfunction was assessed in 60 non-dysphagic and 75 dysphagic patients. All subjects were examined with liquid barium and cineradiography at 50 frames/s.
The inner valence region of CO/Pd(100) p(2 square root 2* square root 2)R45 degrees has been studied by angular resolved photoemission at the Pd 4d Cooper minimum, and with resonant Auger spectroscopy at photon energies corresponding to the C 1s and O 1s X-ray absorption (XA) maxima of the unoccupied parts of the 2 pi *-Pd 4d hybrid (2 pi un). Previously unobserved inner valence states are reveale
Hjalmarsson (2010) considers an OLS-based estimator of predictive panel regressions that is argued to be mixed normal under very general conditions. In a recent paper, Westerlund et al. (2016) show that while consistent, the estimator is generally not mixed normal, which invalidates standard normal and chi-squared inference. The purpose of the present paper is to study the consequences of this the
The EU’s stagnation on many innovation indicators led to a number of efforts to spur a turnaround. One of most visible projects has been the Horizon 2020 strategy, which devotes unprecedented levels of funding to the promotion of R&D and innovation. But does this strategy address the right issues to promote innovation? Is Horizon 2020 right to ignore geographical considerations when allocating
This paper investigates the impact of political risk on financial performance. In order to assess the quantitative measure of political risk principal component analysis is performed referring to six indicators, which measure different areas of political environment. We employ several macroeconomic factors as control variables to strenghten the explanatory power of estimation. Panel data methods a
Purpose: The main purpose of the thesis is to examine the profitability of Momentum Strategies on the Nordic stock markets. This will provide insight and contribute to the debate on efficient markets. Finding profitable Momentum Strategies will provide strong evidence of inefficiency in the market. A secondary purpose is to examine factors which might cause or impact the profitability of the Momen
The effect of two different body positions on tidal breathing. Key words: Tidal volume, body positions, administration, inhalation therapy, inspiration volume Background Inhalation therapy is becoming a more habitual way of distributing different types of drugs. Several factors are important to consider for optimising inhalation therapy. Physiotherapists play a key role in inhalation therapy.
With the proposed Directive by the European Commission to tax the digital economy more effective by introducing a digital permanent establishment, the question raises how to effectively tax it. Under the current profit-allocation principles, profits are allocated to the jurisdiction in which the significant people functions are situated. However, since a digital PE can exists without any people or
Fält-, mikroskop-, och litteraturstudier har utförts för att fastställa karakteristika rörande litologi och fauna i den mellanordoviciska (darriwilian, undre kunda), märkliga “täljstenen” (kalksten) och dess omgivande lager, som går i dagen vid Kinnekulle i Västergötland. En 2,6 m mäktig bergartssekvens har provtagits, resulterande i tunnslip och syraresistenta residualer. Både litologi och fauna Lithologic and faunal characteristics of the anomalous lower Kundan (Darriwilian, Middle Ordovician) 'Täljsten' limestone interval and its enclosing strata have been studied at Kinnekulle (Västergötland, south-central Sweden). A 2.6 m thick rock succession has been sampled, resulting in thin-sections and acid-insoluble residues. Both lithology and fauna change markedly throughout the succe
This paper examines the effect from issuer-sponsored equity research on stock prices in Sweden. This kind of reports has risen in popularity and today, over 290 firms in Sweden are covered by a sponsored equity research. To reach a conclusion, a traditional event study was performed on 141 Swedish firms between the years of 2008 and 2019. The result show that there are significant, at the 1%-level
A common belief is that left-wing parties tend to use their influence to expand the public sector by increasing taxes – but is this belief supported by data? This study aims to find the causal effect of having left-wing majority and left-wing rule on a set of economic and policy outcomes by using panel data of Swedish local governments between 1995 and 2018. A regression discontinuity design is ap
Uppsatsen behandlar asymmetrisk kryptering över ändliga kropper och elliptiska kurver. Elliptiska kurver införs med hjälp av affint och projektivt rum. Uppsaten också ger en introduction till algoritmer som kan knäcka diskret logaritm problemet över kropper och elliptiska kurver.In this thesis, an introduction to public key cryptography over finite fields and elliptic curves is given. Elliptic curves are introduced using affine and projective spaces. The thesis also gives an introduction to algorithms that are able to break the discrete logarithm problem over finite fields and elliptic curves faster than an exhaustive search.
Delivery lead time (DLT) is seen as one of the most important service factors affecting the consumers willingness to fulfill a purchase within online retailing (Esperet al., 2003). The purpose of this thesis is to investigate the effect variations in the offered DLT have on customer conversion rate within e-commerce. This is done by analyzing historical online customer demand data from a case comp
