Handel med utsläppsrätter inom EU - Möjlighet eller papperstiger

This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.

handel med utsläppsrätter : en del av lösningen på koldioxidproblematiken?

In Rio De Janeiro, 1992, was the first document signed that meant a responsibility for industrial countries to decrease their emissions, United Nations Framework Convention on Climate Change (UNFCCC). Thirteen years later was the first legal binding document signed, the Kyoto protocol, and for the first time industrial countries all over the world was bound to decrease their emissions on greenhouse gases. Within the framework of this commitment, three flexible mechanisms (Clean Development mechanism, Joint Implementation and Emission trading) were introduced with the function to reduce the economical costs of the commitment. The flexible mechanisms Emission Trading (ET) is what this report is about.The report starts with a description of carbon dioxide and it?s effect on the environment, thereafter comes a background review of the national agreements who lies as a ground to the implementation of emission trading as a management control measure in Sweden and the rest of the world.Keywords: United Framework Convention on Climate Change, Kyoto protocol, Flexible mechanisms, Emission trading, carbon dioxide .

Audio Identity : En studie i ljudets funktion för varumärkesbyggande

Abstrakt Sound branding är i dag ett begrepp som är välkänt bland marknadsförare. Fördelarna med en unik och genomarbetad ljudidentitet har dock inte nått fram till många svenska företag och varumärken. Vi ämnar med detta kandidatarbete att utforska ljudets funktion för varumärkesbyggande samt skapa förståelse för vilka faktorer som är avgörande gällande ljuddesignen i reklamsammanhang. Genom tidigare forskning samt produktion av sonic logos och musik, åt olika beställare, har vi försökt besvara frågeställningen: Hur ger man verksamheter och varumärken en ljudidentitet? Abstract Sound branding today, is a well-known concept amongst marketers.

Ljudinstallationer i Sveriges utemiljö

When visiting Scaniaparken in Malmö you have the possibility of listening to music streaming out of grass-covered hills. In Helsingborg children can compose their own music and play for their friends on the playground. On a square in Nacka Strand you can hear birds singing in the quiet intervals of traf?c. What the places have in common are that they all contain sound installations.

Undersökning av ljudnivåer på skolgårdar : - samt hur fasad och fönster dimensioneras med uppmätta värden

This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.

Barn och buller : Hur barn och verksamhet på förskolan påverkas av en hög ljudnivå

There are a lot of different sounds in our sound saturated time. Noise is an unwishable soundand a high sound level can give short- or lingering problems for both children and adults.The purpose was to find out if and in that case why children and the activity at the pre-schoolaffects by a high soundlevel. Another purpose was to examine what the effects would be if thepedagogues set about the work to get a good sound environment at pre-school.The investigation was accomplished in shape of qualitative interwievs where six pedagoguesfrom different pre-schools answered questions about a high soundlevel.All of them have been educated to hearing pilotes.The result of this investigation shows that some pre-schools have a high sound levels but notall of them. In those cases where there is a high soundlevel are there often too many childrenat the same place on the same time. That makes the soundlevel even higher and both childrenand adults are getting tired.By improving the sound environment at the pre-school both children and adults often gets abetter activity.Keywords: high soundlevel, hearingpilot, noise, affects on children..

The Sound of Drums - Trumsoundets förändring över tre decennier

Denna uppsats undersöker hur trumsoundet förändrades inom produktionen avpop- och rockmusik från 60-tal till 80-tal och sambandet med förändringar iinspelningsteknik. Uppsatsen syftar även till att tydliggöra hur dagens diskurs omsound har växt fram och hur sound har blivit ett estetiskt verktyg och enkonsumtionsvara. Metoden som har använts är lyssningsbaserad analys ochjämförelser av inspelningar från respektive decennium, samt att resonemang ochresultat i uppsatsen har återknutits till tidigare forskning om sound. Resultatet avanalysen visar att inspelningstekniken har haft en avgörande betydelse för hurtrumsoundet inom berörda populärmusikaliska genreområden har förändrats och dessmöjligheter och förutsättningar satte soundskapande fokus på rummet under 60-talet,instrumentet under 70-talet och effekterna under 80-talet. Undersökningen har visatatt sound på 60-talet relaterades till helhet, plats och person och senare till tekniskbearbetning av enskilda element i ljudbilden.

Akustiskt åtgärdsprojekt av en rockmusikklubb där live-musik spelas. Vad kan en audionom bidra med?

Introduction: The number of hearing impairments in Sweden is increasing. The largest increase is seen in ages 25-44. There are reasons to believe that these impairments are noise induced. Leisure time noise is not controlled in the same manner that industrial noise is. An ongoing conflict between city council officials and rock club owners, musicians and music event organizers about sound levels at smaller live music clubs exceeding the national sound level restrictions created the need for an acoustic intervention project.

Funktionskontroll av stegljudsisolering vid konstnärligt campus i Umeå

This report's aim is that by field measurements determine the function of Aprobo soundproofing material dB2 for reducing impact sounds, the measurements is done in ?the school for fine art? in Umeå also known as ?konstnärligt campus building nine?. The construction technique is used in areas sensitive to impact sound between different floors in the building. The measurement?s is also to do a function control of the buildings sound quality compared to Swedish and European standard when it comes to air sound, impact sound and reverberation time .

Hör upp!!

In this Bachelor thesis I explore sound and room as elements in design of user interfaces, both theoretical and practical in a specific application domain, to identify some of the advantages and disadvantage associated with these elements. As application domain I studied email clients and their usage at home amongst students at Blekinge Institute of Technology. In the study I found an activity, which seems to be highly distributed in the physical room where the user is located. The activity was notification of email and could take place in an arbitrary location of the home. I then augmented this activity with ideas from my theoretical assumption about room and sound.

Servostyrning med binaural ljudlokalisering

People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.

Handel med utsläppsrätter. Ett effektivt styrmedel på den svenska fjärrvärmemarknaden?

In January 2005 the emission allowance system was introduced within the European Union and the first period ends at the end of 2007. The system was introduced in order to decrease the wastes of carbon dioxide and the system is a part of ratifying the Kyoto ?protocol which first period runs between 2008-2012.The idea of the system is to reduce the wastes of carbon dioxide where it costs less to do so and the expenses for the society therefore are as diminutive as possible. Different theories explain that companies can benefit from environment legislation and can depending on the company?s attitude gain competitive advantages improve its productivity and thereby increase its profitability.With this in mind, the study aims at examining how the introduction of the emission trade system has influenced Swedish smaller companies in the distant heating industry, with focus on the factors attitude, innovation, competition and profitability.

Skalkonstruktion : Med inriktning mot hållfasthet och dämpning av ljud

The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.

Spårtaxisystem i Uppsala

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.
