Orienterare, framtidens naturvårdare? : Inventering av markstörningar i samband med O-Ringen i Skåne 2014

As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.

Framtidens mobilnät

The purpose of this project was to study how the interference between two antennas in a MIMO system affects the linearity of the power amplifiers powering the antennas. For the MIMO system, two power amplifiers and twoantennas were constructed and designed using the software ADS and a software defined radio was constructed using the platform USRP and the software LabVIEW. The result was that the interference between the antennas affectsthe linearity of the power amplifiers powering the antennas adversely and a reasonable theory was that the interaction decreases inversely proportional tothe square of the distance..

När ska vuxna delta i barnens lek? : En jämförelse mellan verksamma fritidspedagoger och forskningslitteraturen

This study aims was to examine if working recreation instructors and the technical literature have the same or different outlook on when the grown ups should attend in children?s play, and what it is that separate them. The work method has been qualitative interviews. The number of interviewed recreation instructors is four. The study shows that the working recreation instructors that I have interviewed consider that it´s important to protect children´s freedom in there play without the grown up´s interference.

Effekten av bakgrundsljud på prestationen vid en räkneuppgift

I studien undersöktes effekten av bakgrundljud på prestationen i en räkneuppgift. Två experiment genomfördes för att testa effekten av tre bakgrundstal: irrelevanta tal, yrkesbeteckningar och tal uppspelade baklänges. Dessutom ingick en kontrollbetingelse utan bakgrundstal. Hypotesen var att de irrelevanta talen skulle störa prestationen mest. Experiment 1 visade ingen effekt av bakgrundsljuden och stödde alltså inte hypotesen.

Montagemetoder för axel och rotor

At ABB LV Motors in Västerås the shaft is assembled into the rotor with a shrink fit. After athorough investigation of the assembly method, several factors that make the insertion of theshaft more difficult has been discovered. Some affect the assembly directly while others onlyhave an indirect influence. The investigation has shown that the radial play between the shaftsouter radius and the rotors inner radius might be too small which could lead to anunsuccessful assembly. For the larger rotors, the condition is the opposite, and the rotor mightmove compared to the shaft direct after the assembly when the rotor still is warm.

Implementation of an FFT algorithm using a soft processor core

This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..

Irak : Mellan islamisk identitet och demokratisk process

This is an essay about the political development of Iraq after the overthrow of the Baath regime by the coalition forces in 2003. Almost seven years later, the political scene is still characterised by chaos, even though the country entered a new phase with the adoption of democratic thinking and a new openness to the world. The unstable political situation is a product of inter-ethnic conflict and the interference by neighbouring countries. Iraq is up against two formidable tasks ? building democracy and building a nation.

De mänskliga rättigheternas beskyddare

The Human Rights claim that all humans have special rights that are not allowed to be broken or violated. Although these rights are broken and violated by states every day. One major fact that makes this possible is the principle of sovereignty that includes all states, and which says that every state has the power and right to make decisions and create laws within the own country without the interference of other actors. In other words, the problem is that the states have to much power in relation to actors usch as the United Nations and to the rules of the Human Rights. This essay describe a possible way to strengthen the power of the Human Rights so that all humans can be guaranteed the fulfillment of the rights..

Kina i Afrika : En studie av Kinas afrikapolicy

Since the beginning of the new millennium, China has opened itself to the outside world and in an enormous pace increased its contacts and relationships with other countries. The trigger to these dramatic changes of economic and foreign policies is the insight that China can no longer sustain its rapid economic growth, largely based on industrial production, on energy and raw materials from China alone.Good relations with African countries have been of highest priority in China?s strategy of ?Going global?. The new African policy is based on the two principles of mutual benefit and non-interference in internal affairs ? as opposite to the West?s strategy of structural adjustment programmes (SAP), which include massive interference in internal affairs.

Vad är ett riktigt slut? : en kritisk granskning av genrepedagogiken i arbetet med sagogenren

With this paper the aim is to find out whether there are any differences in how five students from the north part of Africa structures their tales in comparison with the Nordic tale "The emperor?s new clothes". The purpose is to look at how the genre pedagogy can be said to relate to these differences. What happens to the "deviant" structures?Based on literature and research on the subject, I have concluded that there are certain patterns of how a tale "should" be structured based on Western standards.

Undersökning av modulationsscheman för existerande bredbandsteknologier

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

Medskyldig till folkmord? En studie om internationella samfundets inblandning i folkmordet i Rwanda 1994.

The Rwandan genocide 1994 was a well-planned and ethnic based act that killedapproximately 900 000 people. The UN and the colonial powers are getting much attentionand are worldly discussed about the failure of interference before and during the genocide. Inthis study the history of colonial Rwanda will be analyzed and the UN relation will bediscussed. This will be done by examining how the colonial powers have affected Rwandathrough history and how the UN have responded upon the challenges towards Human Rights.Questions about accountability and failure will also be discussed and analyzed. This has beendone by analyzing highly reliable documents and books by NGOs and scholars.

YTTRANDEFRIHETEN OCH MÅNGFALDEN Får man bilda sin egen uppfattning?

This Master's thesis discusses the freedom of speech, the right to freedom of opinion and expression, freedom to hold opinions without interference and to seek, receive and impart information and ideas in the context of public libraries in Sweden. The scope of this thesis is to examine the acquisition and maintenance of the literature about the killing of Sweden's Prime Minister Olof Palme 1986. This literature will serve as an instrument to measure the extent to which Swedish public libraries adhere to the rules set by the Swedish parliament, United Nations' universal declaration of human rights article 19, UNESCO's public library manifesto and the principles of the Federation of Library Associations and Institutions..

Restspänningar i arc-förångade (Ti(1-x)Al(x))N ytskikt

This report is the written documentation of a project work carried out at the Division of Engineering Materials at Luleå University of Technology in cooperation with Seco Tools AB. The project deals with the analysis of residual stresses in Ti-Al-N thin film grown on WC/Co cutting inserts. The composition of Al varied from 0% up to 75%. Increasing the Al content in the Ti(1-x)Alx N compound improves the compressive residual stresses even after annealing of the material. The experiments have been performed in a high temperature x-ray diffractometer (HTXRD) where the interplanar atomic spacing was determined in-situ and subsequent converted into stresses.

Modellbaserad ekoföljning i vätskefyllda tankar

This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.
