Aeroacoustics is the field that studies flow induced sound. The source of sound can for example be fans, duct flows, aircraft propellers and objects mounted on the outside of a vehicle. The most often used computational methods for aeroacoustics are based on acoustical analogies. The software package CALFEM is a finite element toolbox developed for teaching at Lund University. It contains routines to

INTRODUCTION In the last years a lot of researches about source separation have been realized, like extraction of a signal of interest (vocal recognition application), identification of which source gives which sound (motor engine applications) or noise source characterization (environmental application). Most of these techniques for sound source estimation use the signal-subspace approach, where

Issue of study: The starting point for innovation is ideas, which can be seen as fuel to the innovation process as it supplies the innovation funnel with new or improved concepts that finally may spark innovation. There is a vast literature on the success of a few radical ideation methods and the use of creativity tools, while few have dealt with the use and effects of ideation approaches in pract

Despite a fair amount of academic attention being afforded to the South African Police Service (SAPS), one actor within it has been constantly ignored. Considering reservists make in excess of 15% of the overall policing staff (albeit only as temporary staff) in Gauteng this gap is surprising. Reservists wear an identical uniform and carry out the same functions as permanent members but are not re

En geologisk turistguide över Söderåsen i Skåne har utarbetats i samarbete med Svalövs kommun. Syftet med guiden är att öka kunskapen om Söderåsens unika geologi samt tipsa om geologiskt intressanta besökslokaler inom området. Information om geologi och lokaler har inhämtats via skriftliga publikationer, från Sveriges geologiska undersöknings (SGU:s) kartblad med beskrivningar samt genom dokumentaA geological tourist guide to Söderåsen in the province of Scania, southern Sweden, has been made in collaboration with Svalövs municipality. The purpose of the guide is to increase knowledge about Söderåsen's unique geology and to present geologically interesting sites in the area. Information about geology and sites have been obtained through written publications, from map sheets with descri

Traditionally software development was performed by one single company. However, the traditional roles are being redefined and software ecosystems are taking software development outside the borders of the software company. Companies are starting to collaborate by using digital platforms and are creating new complex networks of organizations, so called software ecosystems. Software ecosystems are

Få heltäckande uppföljningar har genomförts för vattenvårdsprojekt. Forskning kring miljöförbättrande åtgärder i vattenvårdsprojekt pekar på ett behov av systematiserade och accepterade metoder för uppföljning av vidtagna åtgärder. Syftet med examensarbetet är att utveckla rekommendationer och tillvägagångssätt för uppföljning av åtgärder riktade mot kväve- och fosforreducering i små avrinningsomrFew comprehensive follow-ups have been carried out for water management projects. Research on environmental improvements in water management projects, indicates a need for systematic and accepted methods for follow ups. The purpose of this thesis is to develop recommendations and approaches for follow-ups of measures reducing nitrogen and phosphorus in small watersheds. The methods used were an in

Title: Critical success factors that influence the corporate venturing process Seminar date: 2013-05-02 Course: ENTN39 Internship and Degree Project Authors: Martin Zündorf & Marcus Holgersson Advisor/s: Joakim Winborg Purpose: We investigated the influence of different factors on the corporate venturing process. Therefore we combined several factors from the organizational level with cha

Definitionen av ofrivillig barnlöshet innebär att ett par aktivt försökt bli gravida under 12-24 månader utan att lyckas. De flesta kvinnor och män i fertil ålder som vill ha barn har också möjlighet att skaffa det men för en minoritet av befolkningen är detta en omöjlighet. Syftet var att belysa kvinnors och mäns upplevelser av ofrivillig barnlöshet. En kvalitativ metod valdes och data samlades i

Purpose: The purpose of this research is to explore possible cost effective strategies for increasing brand awareness amongst certain stakeholder groups of an acquired, previously well known brand operating in a high tech B2B industry. Methodology: A qualitative, exploratory case study of RUAG Space AB, an acquired company previously holding high brand awareness in Sweden, was conducted. This was

This research addresses the role that the media have in guiding public perceptions about social movements and also the importance of the media in a well functioning democracy. In order to do so, a case study of the Indignant Citizens movement of Greece is presented, using theories related to participation, including voice and deliberative democracy. Furthermore, theories regarding the Europeanizat

This thesis is devoted to competition law aspects of parallel trade regulation in the European Union. The long line of case law of the European Court of Justice and the European Commission reflects the changes of the approaches towards the problem of parallel trade restrictions, where the very first cases establish the fundamental framework and policies for development of the internal market throu

Overcrowded units, excessive waiting lists and overstrained personell. Add an aging population and you have some of the challenges facing the Swedish health care system. Change is needed at multiple levels and it needs the involvement of a wide variety of actors. Some researchers suggest that many of the current change efforts fails to honor the complexity of health care organizations. In our the

There is a big discussion regarding the productivity in the construction industry. Many suggestions on how to mend this exist and one example is Virtual Design and Construction – VDC. The three main parts of VDC is the Product, often displayed as a BIM-model, the Organization with the intention to put the right team to every task, the Process which searches for more effective ways to work. With th

The exploration will be focus on aspects regarding RFID technology, like level of knowledge and awareness, the willingness to invest on it, the attitude of the companies regarding the adoption, the

Öresundsregionen besitter genom sin stora befolkningskoncentration en stor potential att starkt bidra till tillväxten i Sverige och Danmark. För att nå upp till denna potential måste emellertid ett rad gränshinder undanröjas, exempelvis hinder för dem som dagligen pendlar från hemmet på ena sidan Öresund till arbetet på andra sidan Öresund. Ett hinder för dessa Öresundsspendlare utgörs av bristenThe Öresund region possesses, due to its large population, a great potential to contribute strongly to economic growth in Sweden and Denmark. In order to reach this potential, however, a series of border barriers must be removed, for example barriers for those who commute daily from their home on one side of the Öresund to their work on the other side of the Öresund. One obstacle for these Öresun
