Pełny tekst źródłaSyftet med studien är att belysa buller i förskolans pedagogiska inomhusmiljö och vilken inverkan det kan ha på barnen som vistas där, samt vilka åtgärder som kan vidtas för att få en god ljudmiljö. Som metod har en enkätundersökning och intervjuer med pedagoger utförts. Dessutom har förskolans inomhusmiljö med barn och vuxna observerats. Undersökningen visar att barn, vuxna, aktiviteter och leksaker skapar en bullrig miljö. Som en följd av detta buller upplever pedagogerna att barnen bli trötta och okoncentrerade, men också livliga och högljudda. För att motverka buller har vissa åtgärder utförts i arbetssätt och miljö, men pedagogerna upplever att bristande kunskap, tid och pengar hindrar dem i vidare arbete.
Trots att det finns lagar och rekommendationer återstår det mycket att göra för att skapa en god ljudmiljö för barnens fortsatta utveckling och lärande.

Pełny tekst źródłaThis thesis evaluates whether walls with light-frame construction are suitable to build in areas with high sound pressure levels, allowed by Sweden’s law regarding loud traffic noise nearbuildings. Previous consensus has been that exterior walls have sufficient sound insulation,regarding sound pressure levels by the residence-façade generated from traffic noise, to achieverequired indoor sound pressure levels. Due to the ongoing urbanization in Sweden, a law haspassed that increased the allowed levels of equivalent sound pressure by a residence-façade. Therefore, it has become relevant to examine if light-frame construction façades really do have sufficient sound insulation.In the study, field measurements are made on three façade walls to determine their noise reduction properties. The values from the measurements are compared to the sound insulation capacity of software-built wall-models with the same wall constructions as the field measured walls. Both the measured and the modelled walls sound insulation is also compared parallel to insulation values for light-frame construction walls found in literature. The values of the walls sound insultation are also evaluated regarding high but occurring sound pressure levels by facades and demanded levels of sound pressure indoors. Modifications are made to the construction of one modelled wall to quantify the improvement in sound insulation of the walls derived from the investigated construction-modifications.The results conclude that the examined light-frame construction walls are indeed sufficient in the aspect of sound insulation to merely satisfy the laws. The walls sound insulation is not as unambiguously sufficient when establishing what is considered a good indoor acoustic environment, instead of only achieving minimum levels required by law.
Sauvaget, Tabatha. "Formation des pseudo-bulbes dans les galaxies spirales locales de masse intermédiaire via des fusions majeures riches en gaz". Thesis, Paris Sciences et Lettres (ComUE), 2017. http://www.theses.fr/2017PSLEO012/document.
Pełny tekst źródłaBulges are present in almost 80% of nearby spiral galaxies of intermediate mass. Spiral galaxies represent about 70% of the intermediate-mass galaxies (typically with a mass between 2 × 10^10 and 10^11 solar masses) in the local Universe. While classical bulges have been associated to the result of major mergers, pseudo-bulges have been rather associated to secular evolution. However, the cosmological ΛCDM model predicts a hierarchical growth of galaxies via mergers while pseudo-bulges are found in > 50% of large nearby spiral galaxies. The aim of this thesis is to verify if we can build pseudo-bulges with gas-rich major mergers. The first part of this thesis is devoted to the presentation of the subject and the state of the art on the formation and evolution of galactic bulges.The second part of this thesis is focusing on the methodology developped to analyse bulges of spiral galaxies and understand their formation. The thesis has two axes of study, an observational part with the analysis of two complete samples of local spiral galaxies of intermediate mass to determine the proportion of pseudo-bulges in these samples and to have a reliable reference. Another part, which is the core of the study, is dedicated to the analysis of nume- rical simulations of gas-rich major mergers done with a N-body / SPH code (GADGET2). The aim is to reproduce this type of galaxy and to study their properties thanks to a bulge + disk decomposition.In the third part, I show that, within the limits given by the simulations, we can reproduce spiral galaxies with pseudo-bulges via gas-rich major mergers. This thesis propose a new scenario of pseudo-bulge formation thanks to the formation of a bar, which bring gas into the central parts. In addition, most of the observed structures, such as bars, rings or double-disks, are reproduced in the simulations. The different parameters of simulations has been then modified (gas fraction, mass ratio, mass of progenitors, feedback, gas extension, pericenter) to explore their impact on the results. We found that the disparities on Sersic index and B/T ratio comes as much from the difference between orbits as from between initial physical parameters chosen for simulations but we can still extract some trends. For instance, I show that the higher the gas fraction of the progenitors, the lower the Sersic index and the B/T ratio, the more the number of bars and their size increases

Pełny tekst źródłaThis report covers projects E05 Korsvägen where the client is Trafikverket and the contractor West Link Contractors, WLC. We have chosen to examine a subject for the project and chose to immerse ourselves in noise issues. Korsvägen is a substage of the West Link built in central Gothenburg. The project will affect the environment with noise from the construction site. It is therefore interesting to investigate how the environment is affected and how workers and entrepreneurs within the project experience a noisy work environment. Furthermore, as there are increasingly large complex infrastructure projects, it is interesting to shed light on how WLC is working to achieve the requirements regarding noise. The report is a combination of quantitative and qualitative methodologies. The quantitative part consisted of two surveys. One survey examined the experience of nearby companies regarding noise disturbances from the project. The second survey examined how workers in the project are affected by noise in their daily work. For a deepening of how noise issues are handled within WLC, qualitative telephone interviews were conducted with selected people from the project. The results found that workers in the project are not sufficiently aware of the consequences and health effects caused by noise. Today there is no requirement to use hearing protection in the construction area, however, hearing protection should be used as needed when noisy work is carried out. Many workers believe that the use of hearing protection should be a requirement. The survey shows that noise from the project affects the surrounding activities and that the dissemination of information on noise disturbances is important. The noise requirements imposed against WLC have caused exemptions to be sought for certain noise-critical work operations. It also proved to be a challenge to work on these requirements for such a large project with many actors involved. Workers ' awareness of how noise affects health can be questioned. Although their daily work is perceived as noisy, they seem unaware of how noise can affect their future health. This is a health and safety issue that should be addressed. Improvement areas concerning noise issues are better communication between the parties involved and ensuring that information on noise disturbance reaches all concerned.

Pełny tekst źródłaSyftet med studien är att ta reda på hur buller i förskolan påverkar den pedagogiska verksamheten, med utgångspunkt från pedagogers upplevelser och erfarenheter av ämnet. Studien utgår från intervjuer med verksamma pedagoger i förskolan och en observation på en förskoleavdelning. Bakgrunden bygger på information samlat från böcker, tidskrifter och webbsidor.
Buller i förskolan anses av informanterna vara ett problem eftersom både barn och pedagoger far illa av att varje dag vistas i en miljö med hög ljudnivå. Det leder bland annat till att både barn och vuxna blir stressade, koncentrationsförmågan blir försämrad samt att det kan leda till hörselnedsättningar. Det är pedagogens uppgift att skapa en bra ljudmiljö där man kan bedriva en bra pedagogisk verksamhet. I en väl fungerande förskola ska det finnas utrymme för varierande aktiviteter. Barn har behov av dels lugna och tysta aktiviteter men även av fysiska och livliga aktiviteter som gärna blir högljudda.
Vi vet att barn låter när de leker och att de måste tillåtas att leka högljudda lekar även i förskolan. Vi anser att man som pedagog inte ständigt ska försöka att dämpa barnen, då det kan störa deras leklust. Det är inte barnen som ska anpassa sig efter omgivningen utan det är omgivningen som ska anpassas efter barnen. Vi tycker att det är viktigt att rum i förskolan inreds med ljudabsorberande material på väggar, golv och i taken. Då kan barnen leka livliga lekar utan att orsaka en hög bullernivå.

Pełny tekst źródłaA problem in today's modern society is that the noise levels are too high. These high levels of noise is a health hazard and can give man permanent damage. Noise pollution is something that must not be neglected. The purpose of this study is to identify and map the noise on Holmgatan in central Falun. The purpose is also to analyze the results and put them in relation with the regulatory requirements and guidelines regarding noise levels and to analyze the results and see if actions should be taken against the noise on Holmgatan. The thesis is limited to noise measurements and mapping of parts of Holmgatan, considered to be especially vulnerable to noise. Noise measurements were conducted during four weekdays and during times from when most stores open to most of them then closing, at. 10-18. The method consisted of noise measurements which were performed at hourly intervals along the selected portion of Holmgatan. The days on which these measurements were performed was from 2/12 to 5/12-2013. The results are reported as average value per hour of any day on which noise measurements were made. The results varied, the lowest average noise was 57 dB and the highest average noise was 83 dB. It is clearly seen that the higher values are closer to a street used by buses and other transport vehicles. The lower values were generally near Geislerka parken, which is a large garden, an open area in the middle of Holmgatan. Overall, the average noise values were between 60-65 dB. The conclusion suggests that the noise level at Holmgatan do not exceed regulatory requirements on what is considered as harmful but it is just below the guidelines for the maximum level of outdoor noise (70 dB). Actions such as planting vegetation on the facades and to redirect the traffic could be done to reduce noise levels at Holmgatan.

Pełny tekst źródłaThis study highlights the intensity and the extent of sound levels produced by a so called floating floor. The study has closely observed floor constructions made of Platon mat in order to detect the acoustic factors and how they are manifested when stepping on the floor. The study also compares the results of step- and drum sound levels with Granab constructions, another type of floating floor, as well as how the Platon construction stands in relation to the statutory guide values. This study has focused on how the sound from a Platon floor is perceived in an objective and a subjective perspective, because in some cases measured values do not correspond to the actual experience. Measurements that have been carried out give an idea of how to design floors and what type of material should be used to obtain the most favorable sound level possible. Overall, this study shows that the design of the floors can, to a large extent, minimize step- and drum sounds. This knowledge can be of great use when designing a floating floor since it has been shown that high sound levels in the lower frequencies affect, among other things, our abilities of learning and concentrating.

Pełny tekst źródłaMany of the Swedish municipality’s wants to increase the density of housing and commercial buildings in the city. The ambition is to fill gaps and use vacant lots that have not previously been built upon.The paper deals with the problems that traffic noise creates and that has to be addressed when planning new apartments. It also investigates the regulations that governs the technical design and plan of apartments with regard to traffic noise. Skanska have previously experienced difficulties with getting building permits approved if the plan incorporated bedrooms facing towards the traffic noise.The focus is on regulationsand general advice that governs the locations of bedrooms and tries to find solutions that makes it possible to get building permit with bedroom facing the noisy side. To find a solution to the problem we have examined the following: Laws and regulations like PBL, PBF, BBR and Boverkets general advice. How Örebromunicipalityapplies regulations and general advice. If different municipalities in Sweden applies regulations andgeneral advice in the same manor. Examinationof the sound-absorbing propertiesof available wall constructions and windows to find out if it is possible to fulfill guidelines regarding sound level in bedrooms. If there is a useful difference in sound level outside the wall for different floors in buildings.

Pełny tekst źródłaNoise from the ventilation systems affects us more or less every day. There are some requirements on how much noise that’s allowed to generate from the ventilation system set by Karlstads Kommun based on Boverkets Byggregler. But how could a more silent system be constructed at a more stringent level of requirements? The aim is to investigate a reasonable sound level based on technology and economics. Based on Råtorps preschool, owned and operated by Karlstads Kommun, performed calculations using the existing calculation template and sound measurement according to a Swedish Standard. It is done to find out how the sound environment of preschool looks like today in relation to the requirements set. An analyze of the staff's perception of sound generation from ventilation to be able to consider what is an acceptable noise level. Subsequently, calculations are made to find out which theoretical improvements that can be done, especially technically and also financially, in order to reduce the noise level. According to the noise measurements that are made, the noise level at the preschool is below or at the same level as the requirements. The results are consistent with the calculations performed in addition to the room that previously was in line with the requirements, now is over the limit. The noise from the ventilation is perceived as disruptive in two of the four rooms, but the results of the theoretical improvements are showing that it is possible to reduce the noise to a more acceptable level. This can be done without major financial consequences, than the most costly and improvement measure that was tested found to be least effective in lowering the noise level. This work results in that even though the set requirements are followed as perceived ventilation to some extent as disturbing nonetheless. It would be possible to reduce noise generation with relatively small funds without excessive economic consequences and thus create a better working environment.

Pełny tekst źródłaArbetets syfte är att genom en textanalys av olika forskningsarbeten upptäcka sambanden mellan textila fibermaterial, buller och ohälsa med inriktning mot det öppna kontorslandskapet och det lågfrekventa ljudet. Utifrån syftet besvaras följande frågeställningar: Vilka kunskapsområden blir synliga vid tillverkning av textila ljudabsorbenter med inriktning mot det lågfrekventa ljudet? Vilka kunskapsområden kan en tillverkare av textila ljudabsorbenter behöva belysa utifrån ett specifikt ljudproblem?
Frågeställningen besvaras genom en kvalitativ dokumentstudie där textmaterialet består av forskningslitteratur, facklitteratur och artiklar. Syftet är att utveckla nya perspektiv kring textila ljudabsorbenter. Genom att ge inblick kring ljudets beteende och skapa insikter kring hur buller påverkar hälsan. Detta för att få en så bred kunskapsspridning som möjligt gällande textila ljudabsorbenter för att finna samband mellan olika berörda områden.
I resultatet framgår det att textila fibrer har betydelse vid tillverkning av en textil ljudabsorbent. Betydelsen ligger i att olika textila fibrer får varierande ljudupptagningsförmågor beroende vilken grovlek, längd och behandling materialet utsätts för. Likaväl är varierande kunskaper av vikt utifrån rummets utformning, ljudets påverkan på hälsan och kring ljudets akustiska egenskaper. Kunskaper från olika områden som sedan kan vävas samman vid tillverkningen av textila ljudabsorbenter.

Pełny tekst źródłaThis degree project will examine active sound design for quiet vehicles. Based on former research wether electric cars expose humans living in urban areas to danger due to the absence of auditive information, we will develop suggestions for dynamic eninge sounds which are related to traffic safety, design and reduced noise pollution. Cities’ overall noise levels are far beyond recommended, and the consequences causes health issues in bigger cities. This paper will therefore discuss the problems with noise pollution in cities, and wether the electric car is capable of reducing the overall sound levels while maintaining pedestrians’ and cyclists’ awareness in traffic by auditive information. Our interpretation resulted in engine sounds which not only contains a causionary effect on it’s surroundings, but also could contribute to the reduction of noise pollution in comparison to combustion engines.

Pełny tekst źródłaIn this essay I’ve researched workplace based knowledge and how companies can benefit from using it. The combined knowledge of a company work force is a powerful tool, and if you could tap that resource both the employees and the company can benefit. I have researched how this knowledge can be used in educating new employees and how this can empower the employees by giving them more control of their workplace. I advocate handing over more control of the factory to the employees. They work with the machines everyday, and often know the best way to run them, and therefore should be the first to be consulted when optimizing the workflow. I have done this thesis project with the Swedish company Jidoka Innovation AB which with their method set by the name HelpMe, specializes in workplace learning and optimization. My case the Santa Maria tortilla factory in the south of Sweden where I evaluated and developed Jidoka’s methods to see if this way of working could make a more efficient production process.

Pełny tekst źródłaStudien handlar om barnens fysiska miljö på Montessoriförskolor och traditionella förskolor och hur buller och ljussättning påverkar barnen. Undersökningen utfördes med en kvalitativ metod och med ostrukturerade observationer. Intervjuerna genomfördes med pedagoger och barn på tre Montessoriförskolor och tre traditionella förskolor. Samtliga pedagoger som blivit intervjuade var medvetna om de höga ljudnivåerna och försökte förhindra att de uppstod. Men vissa skillnader framkom eftersom pedagogerna på Montessoriförskolorna ansåg att de hade en lugn och harmonisk inomhusmiljö medan pedagogerna på de traditionella förskolorna ofta upplevde sin miljö som högljudd. Orsaken till de höga ljudnivåerna berodde på att det förekom större barngrupper på de traditionella förskolorna än på Montessoriförskolorna. På alla förskolor utom på en Montessoriförskola förekom det lysrör som belysning i huvudsak men alla pedagoger tyckte att ljussättningen fungerade bra. I resultatet kan man se att ett fåtal av barnen tyckte det var jobbigt med höga ljud och när andra barn bråkar och springer inomhus.

Pełny tekst źródłaOne of the major environmental disturbances in Sweden is traffic noise, over 1.4 million people are estimated to be exposed to noise exceeding 55 dB. Noise is a health issue, not life threatening but it affects both health and the quality of life. Noise can for example disturb sleep, cause hearing problems, create difficulty in concentration and longtime exposure can lead to problems with the cardiovascularsystem. The purpose of this rapport is to investigate how noise protection can be integrated in the facade and the design of a building. The report is based on two questions.1-what types of noise protection may be suitable for integration into the building's outer layer?2-how can noise protection be integrated as part of the building’s design? The questions included in this report are answered with the help of a literature study, analysis, and sketching. The Literature study contains information on the different types of noise protection. Examples of such protection is noise barriers, vegetation and exterior corridors. Studies of reference objects and the detail plan are the parts that formed the analysis. Based on these two elements, sketches with appropriate solutions were illustrated both in form of hand sketches and 3D models. Noise protection such as noise barriers often require a lot of space and can be difficult to integrate into an urban area. To counteract noise, it is important that already in the planning stage consider noise problems. This to enable and provide a good acoustic environment. Consideration of climate and level of exposure should always be taken when selecting noise protection, this when certain conditions are not favorable for all kinds of protection. The noise protection we investigated was evaluated regarding its ability to be integrated and its suitability for the property to which the work is based on. Following evaluation, exterior corridors with a glass façade, green roof and a design of the building which provides good opportunities for a “tyst sida” were chosen.

Det är då intressant att studera partiklar och buller nära högt trafikerademotorleder som går genom bostadsområden i städer, vilket kan orsaka hög exponering för denärboende och de som jobbar eller av annan anledning vistas i området. Det är då intressant hurolika typer av barriärer mellan väg och bostadsområden påverkar partiklar och buller. Dels har detundersökts vilken inverkan bullerplank har på partikelhalter och bullernivåer nära vägen och dels harhalterna och nivåerna på innergårdar nära vägen studerats. För att mäta detta har en portabel mätstation konstruerats, där en partikelmätare (DustTrak), enmikrofon och en GPS-mottagare kopplats ihop med en enkortsdator (Raspberry Pi). Datat har loggatsoch processats i enkortsdatorn. Mätningar av bullerplankets effekter gjordes på 8-10 mätpunkter på olika avstånd från planket. Vidvarje mätpunkt skedde en 15 minuter lång mätning, där medianvärden sedan togs ut ochanalyserades. På och kring innergårdarna gjordes 5-7 mätningar på olika intressanta platser påinnergården, samt framför och bakom innergården. På grund av tidskrävande mätningar kunde endast tre mätningar göras vid varje mätplats, såresultatet i denna rapport får ses som en fingervisning på hur det kan se ut. I studien sänker ettbullerplank partikelhalterna kring 50 % direkt bakom planket och har en sänkande inverkan upp till 40 meter från planket då vinden är riktad från vägen. Planket sänker bullernivån direkt bakomplanket med 16 resp. 12 dBA för ett nytt plank av glas och betong resp. ett gammalt av trä. Bullernivån sänks åtminstone inom ett avstånd av 100 meter från planket. I studien skyddar en gammal helt omsluten innergård bättre mot både buller och partiklar än ennybyggd bullerskyddad innergård med flertalet öppningar. Vad gäller partiklar gick det inte att finnanågon skillnad mellan halterna på och utanför den bullerskyddade innergården. Den helt omslutnainnergården hade däremot 20 % lägre halter än utanför för en typisk bakgrund och trafikutsläpp. Vadgäller buller hade båda innergårdarna en sänkande inverkan på kring 6-7 dBA jämfört med utanförinnergårdarna. På den bullerskyddade innergården var dock denna sänkande inverkan svagare närainnergårdens öppningar.

Pełny tekst źródłaThis thesis deals with the interplay between the financial and real sectors of the economy. This thesis consists of four chapters. In the first two chapters, we study the existence and endogenous fluctuations of rational speculative bubbles, as a source of volatility in asset prices, taking into account the financial imperfections at the household level. We argue that the existence of a portfolio choice and financial frictions promote the emergence of bubble fluctuations and endogenous business cycles. In this context, we analyze the stabilizing role of fiscal and/or monetary policies. In Chapter 1, we show that a monetary policy responding to asset prices can stabilize the economy as a whole. In Chapter 2, we compare the stabilizing virtues of a progressive taxation on capital income with those of a monetary policy managed by a Taylor rule. We show that a progressive taxation on capital may rule out endogenous fluctuations, whereas a monetary policy under a Taylor rule has a mitigated stabilizing role. In Chapter 3, we study, the existence of rational bubbles in a two-country economy, and the international transmission of their bursting. A bubble bursting in a country necessarily transmits to the othercountry. The effect of a bubble crash in one country onthe bubble issued by the other country can be positive or negative. In Chapter 4, we analyze the role of heterogeneity on the dynamics of asset prices and inequalities when economic agents have preferences for wealth. Heterogeneity in preferences, but also in income, can heighten social inequalities and increase the asset price in the long run, but also promote asset price volatility in the short run

Pełny tekst źródłaThe work developed in this thesis concerns the development of first order two-fluid models deduced by reduction of second order closures. The adopted reasoning allows to preserve the physical contents of the second order relations closure. Analysis of the turbulence structure in homogeneous uniformly sheared bubbly flow allows to deduce a formulation of the two-phase turbulent viscosity. The eulerian two-fluid model was then generalized with the case of the inhomogeneous flows with low void fractions. The numerical results obtained by the application of this model integrated in the computer code MELODIF in the case of free sheared turbulent bubbly flow of wake made it possible to analyze the modification of the characteristic scales of such flow. The two-fluid first order model is generalized finally with the case of high void fractions bubbly flows where the hydrodynamic interactions between the bubbles are not negligible any more

Pełny tekst źródłaThis thesis offers a historical journey through the evolution of the leitmotiv of the bubble, from the prolegomena of the antiquity and baroque eras to modern literature, as well as a reflection on its expression and its literary meanings, and more particularly in poetry, through the study of a few exemplary poems. From the formation of its fascinating iridescent reflections to its bursting, the leitmotiv of the bubble leads us to ponder the relationship between the subject and the fragile beauty of the world around him. The leitmotiv evolves, however, depending on the value the periods and the authors grant to this ephemeral beauty, oscillating between moralising exemplum and aesthetic ideal, between the representation of the Vanity of all things, and that of a transient flash of being. The study of this fragile leitmotiv brings us to consider more encompassing poetic questions: that of the details and of the ephemeral. The bubble, isolated as a detail, leads us to reconsider, within the semiotic system of a literary piece, the meaning tied to fine leitmotivs that could first appear insignificant. With its diverse cultural implications, the ephemeral makes us question the notions that postulate a subjective relationship between the individual and his perception of the world and of time. This singular leitmotiv also involves a spatial thematic: the bubble, blown or emerging from a liquid, takes upon a characteristic spherical shape, which metaphorically evokes creation, whether divine or literary. From this inventory of the various cultural implications of the leitmotiv, and considering its composing elements and its evolutions, we will study how it is employed through exemplary texts by a few authors such as : Gregory of Nyssa, Desiderius Erasmus, Crashaw, The Cardinal de Bernis, Chénier, Vigny, Hugo, Musset, Gautier, Baudelaire, Claudel, Tzara, Reverdy, Ponge, Bonnefoy and Jaccottet

Pełny tekst źródłaBoth experimental and numerical studies have been performed in aIder to highlight the influence of the bubbles density on the drag law. Important results concerning the relative velocity of bubbles in a swarm have been obtained thanks to laser Doppler velocimetry and optical probe measurements in a pure water / air bubble column. Ln particular, it has been shawn that the relative velocity decreases with the local void fraction up to a critical value of 15 % and increases beyond. These evolutions result from a competition between various phenomena, such as turbulence, hindrance and wake acceleration effects. Based on these conclusions, a drag correlation was obtained and tested in a Computational Fluid Dynamics (CFD) code. The significance of the drag law formulation has been demonstrated, especially for the correct description of the transition between the flow regimes of a bubble column and for the accurate prediction of the liquid velocity profiles measured
