Aktiv bullerdämpning i ventilationssystem

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

Functional Cuts

Our everyday life is becoming more active and the activities we perform influence the way we dress. Due to an increase in activities undertaken in an urban environment, demands are changing and the need for active wear that meets the new demands follow suit. The four characters represented in the research can be seen as a reflection of the functional features needed, including base layer, mid layer/insulation and shell.Despite the increase in activities, most of our clothes are still constructed on static dummies or drafted on a table in 2D and the main developments within the active sportswear field is driven by material innovation. By creating garments on a body in movement, my aim is to develop new functions and expression in active sportswear through construction.Construction methods in active sportswear are examined and understood through observations and reconstructions and constitute the foundation of a study of movement for a design recovery.The movement and features required for leading an active urban life sets the direction of the development of new func- tional garments. A series of trial and error sessions and draping fabric on a live model in movement created the prototypes used in functionality tests to establish their feasibility.

Metodundersökning av tre metoder för kvävemätning i en arktisk äng : Jämförelse mellan mätmetoderna extraktion, inkubation och jonbytesmembran (PRS-sond)

The purpose with this report was to compare three commonly occurring methods for measuring plant available nitrogen in soils. The methods extraction, incubation and Plant root simulator (PRS) probe - an ion exchange membrane (Western Ag Innovations, Inc., Saskatoon, Canada) method were used and comparison between these methods were conducted. A full factorial experiment were set up in northern Finland with the treatments excluding herbivores, warming and fertilization to see how the inorganic nitrogen content in the soil was effected by the treatments. Soil cores were taken and from them a subsample was incubated for 18 days and thereafter analyzed for inorganic N in laboratory. PRS- probes were in the ground for 1 month.

Förutsättningar för mellankommunal översiktsplanering Örnsköldsvik?Umeå : En tematisk dokumentanalys

The aim of this study is to investigate a specific form of Special Interest Tourism (SIT), namely health- and fitnesstravels. This kind of travelling is studied from a Swedish perspective and includes aspects like gender and age in active tourism. It also includes which travel motivations that lies beyond the choice of an active vacation.The study is based on a survey that was sent in an e-mail to the health tourism company InShapeTravel´s customers. The answers to the survey has been analyzed and related to earlier research about active tourism.The result shows that more women than men participate in the kind of healthy travels that InShapeTravel offers. A majority of the respondents are between 41-60 years old and the most common travel motivation was ?Better physic/psychic wellbeing?. .

Seniorers motivation till motion : En kvalitativ studie om seniorers strävan mot ett aktivt och friskt liv

This qualitative study investigated what factors influenced older adults to motivate themselves to continue to be pshysical active in their later life. Six individuals, both men and women in the ages of 65-89, were interviewed. The interviews were analysed by informal content analysis. The results showed that there is a certain group who had a strong will to lead a long, well-conditioned and sound life. Although, the seniors are getting older, they continue to make active choices about physical activity on a daily basis.

Marknadsundersökning av Södra skogsägarnas medlemmar inom Gislaveds verksamhetsområde

This study is done on behalf of Södra skogsägarna in the autumn of 2012. The main purpose of the study is to get an explanation to why some of the members are passive in their forestry, and how Södra can stimulate them to become more active. To achieve this a questionnaire study was conducted on the members of Södra in the community of Gislaved. The result of the study shows that there are many different factors that influence whether the forest owner is active or not. Examples of those factors are timber prices, the forest owner's objectives and the forest owner's financial situation. The main goal for the forest owners in the survey was to obtain high economic result and to increase the standing timber volume for the next generation.

"Halfpipe Active Channel"- developing a secure communications protocol

With the advent of powerful multimedia capable mobile phones, the market for mobile services is flourishing. Zenterio AB's Halfpipe Active Desktop is a complete distributed mobile service platform a with a powerful server and platform-independent client. The communication between the client and server takes place over a GPRS-capable mobile network. The purpose of this thesis is to develop a secure communications protocol for use between the Halfpipe Active Desktop client and server. This is done by determining requirements, analyzing candidate protocols and then by designing the final protocol.

Personlighetstyper och stressrespons hos djur ? med fokus på hund och häst

Animals living in captivity are often subjected to various kinds of stress. Individuals within species can respond differently to the same stressor depending on differences in coping style and physiology. Active and passive coping is a common way to describe different coping styles in animals and it is likely that these strategies have a high heritability. Individuals with an active coping style are characterized by an urge of control and a higher level of aggression than individuals with passive coping style, who in general are more flexible and respond to stress by immobilisation to a greater extent. The aim of this bachelor?s thesis is to investigate the presence of different coping styles and personality types in dogs (Canis lupus familiaris) and horses (Equus ferus caballus) and to find fields of application for this information.

Deriving ECA-rules from timed-automata specifications.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Aktiv- och Indexförvaltning : - Kan svenska investerare få högre riskjusterad avkastning genom aktiv förvaltning?

Nearly 74 percent of the Swedish population invests in funds and the options are therefore various. The Swedish private investors can choose between active and passively managed funds. Fund managers, who seek to generate higher returns than the market, manage active managed funds. Unlike the active managed funds, passively managed funds do not require any active investment decisions.Fama?s (1970) efficient market theory reflects all available information in the stock price, therefore it is not possible to predict how the stock price changes.

Förskollärares föreställningar om aktivt deltagande i leken : Deltagare eller åskådare?

The purpose of this study is to highlight how preschool teachers reason about their own beliefs about their active participation in the play. The study is a qualitative research method where interviews have been used to talk with four preschool teachers to obtain their perceptions of their participation in the play. I have approached my questions through previous research and theses which turns to play and preschool teachers' involvement. The result of my study shows that preschool teachers see differently on their active participation, but they think that active participation is essential for the development of the play and that by being involved in the play in different ways will create interaction and interactivity. The result also shows that preschool teachers find great joy in participating in the play, and also that many relationships will be established by participation in the play..

Man kan inte göra mer än att rösta - en studie av ungdomars upplevelse av sitt deltagande i demokratin.

Participation of the people is essential for a democracy's vitality and survival. In this study we focus on the individual as an active participant in the traditional political arena and beyond its sphere into the society as a whole. The first part of the study has a normative aim. Firstly we examine why political participation is essential for democracy, and especially the ideal of representative democracy and the restricted passive participation of its citizens in comparison to the ideal of participatory democracy and its ideal of an active participant in all aspects of society. An ideal participant is drawn up to set the course for the empirical part of the study.

Personlighetens inverkan på aktivt och passivt jobbsökande, karriärambition och arbetstillfredställelse

Previous research has focused limited attention on how personality affects job search for university educated people in work and no studies have focused on the difference between active and passive job seekers. This survey-based study that examined university educated economists and engineers with 5-25 years of experience, showed that career ambition mediated active job search for the personality dimensions of openness, agreeableness and extraversion and also gave clear evidence that active job seekers have lower levels of job satisfaction, and higher levels of career ambition, agreeableness and extraversion, compared with passive job seekers. These findings provide a more nuanced picture of the impact of different recruitment strategies and provide a starting point for in-depth studies on passive job seekers.
