This paper treats estimation of the Wigner-Ville spectrum (WVS) of Gaussian continuous-time stochastic processes using Cohen's class of time-frequency representations of random signals. We study the minimum mean square error estimation kernel for locally stationary processes in Silverman's sense, and two modifications where we first allow chirp multiplication and then allow nonnegative linear comb
This report is a result of a Master Thesis made at Volvo 3P and the Department of Advance Engineering and Concepts. The thesis is a part of the education in Mechanical Engineering at the Department Design Sciences, for the Division of Machine Design at Lund University. Volvo 3P is involved in a project regarding a new patented manufacturing method that is under development. The manufacturing metho
This thesis addresses the correlation between creditor protection and thecross-border seat transfer of companies in the light of the case law of the European Court of Justice concerning the freedom of establishment of undertakings. After the restrictive outcome of Daily Mail, the judgment of the European Court of Justice in Centros took the legal community by surprise. The following cases of Übers
In recent years, land acquisition has escalated due to increased global demand for food and fuel driven by population growth, urbanisation, and growing energy demand. Mozambique is ranked as one of the world’s top 10 countries with available land for agriculture, forestry and livestock production. Low labour costs and land taxes may further increase the interest in Mozambican land. In particular,
The fluctuations of the price in the energy market affect the households, firms and the government intuitions. We can perceive the information of the energy market from daily economic news. The entire society is concerned for the events that affect the energy market and the changing prices of the energy resources. It is thus meaningful and interesting to study the risk of the energy market. This p
We prove a uniqueness result for autonomous divergence-free systems of ODE's in the plane and give an application to the study of water flows with vorticity.
In this paper we present algorithms to compute finite state automata which, given any rational language, recognize the languages of normal words and n-chains. We also show how these automata can be used to compute the Hilbert series and Poincaré series for any algebra with a rational set of leading words of its minimal Gröbner basis.
Historically, labor supply elasticities have been used to evaluate tax policy and predict tax revenue effects. They are likely to underestimate taxpayers' response to tax rate changes, and hence to underestimate changes in potential tax revenues, however, because they measure only how taxpayers alter hours worked. Taxpayers can also respond to tax rate changes by altering, for instance, their work
Building on the growing body of literature bridging international relations and historical sociology, this article argues that "consolidologists" have something to learn from this field. The discussion's point of departure is contemporary writings on sovereignty, security, and state formation in the African context. In an effort to synthesize insights from international relations and historical so
This document was prepared as part of the briefing material for the Workshop of the CERN Council Strategy Group, held in DESY Zeuthen from 2nd to 6th May 2006. It gives an overview of the physics issues and of the technological challenges that will shape the future of the field, and incorporates material presented and discussed during the Symposium on the European Strategy for Particle Physics, he
Objective: Previous research using personality traits to predict life outcomes has typically utilized the Big Five factors and, occasionally, their facets. However, recent research suggests that using items (reflecting personality nuances) can account for greater predictive variance. The present study examines the predictive validity of the different levels of the personality trait hierarchy (fact
Cancer immunotherapies activate the immune system to overcome tumor resistance and restore the antitumor immune response, however, excessive activation of the immune system may also affect normal tissues and organs and cause immune-related adverse events (irAEs) of varying severity. Current in vitro assays used for testing and predicting of irAEs induced by immunotherapeutics are associated with s
Tri-isopropylsilyl thio-glycosides (TIPS S-glycosides) were synthesized through base promoted SN2 substitution of glycosyl halides with TIPS-SH or by Lewis acid promoted glycosylation of TIPS-SH with glycosyl acetates or p-methoxyphenyl glycosides. Various thioglycoside derivatives were obtained in high yields by one-pot fluoride-mediated de-silylation and thiol alkylation with alkyl halides or Mi
When flying through narrow spaces, insects control their position by balancing the magnitude of apparent image motion (optic flow) experienced in each eye and their speed by holding this value about a desired set-point. Previously, it has been shown that when bumblebees encounter sudden changes in the proximity to nearby surfaces - as indicated by a change in the magnitude of optic flow on each si
