The number of data centers and their capacity is increasing throughout the world. Theenergy used in these data centers and the emissions from the use are increasing at thesame rate. The total use of energy will double from 2008 to 2011 based on the trends indata centers use. Research in this area says that the emissions from data centers willhave surpassed the level of airline traffic in 2020. The index used today to compare howefficient a data center is, called PUE, is lacking some information.

Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews.          The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.

Syftet med denna studie är att undersöka hur musiker ser på begrepp som ljudnivå, musikupplevelse och relationen mellan dessa. Underlaget för studien är sex intervjuer med musiker och ljudtekniker, med och utan hörselskador. Studien byggs på sex kvalitativa intervjuer och är avgränsad till att i första hand behandla detta inom musikstilar vilka är baserade på trummor och bas ? pop/rock, jazz/blues.Studiens resultat visar att parametrar som t.ex. genre, lokal, ljudteknik, ljudtekniker och arrangör har inverkan på det ljud och den ljudnivå som uppnås vid en konsert.Vidare redovisas respondenternas syn på relationen mellan ljudnivåer och musikupplevelse.

On the basis of the mapping of the flow, the group discovered that the flow of material had some improvement potential.

Traditions are something that is very important to many people, Christmas is usually no exception. Christmas tree, Christmas ham, herring and candle lights are just as important as the advent candlestick. The advent candlestick help you get the Christmas feeling during the countdown. In this report the work with a new advent candlestick concept can be followed step by step.A lot of information was needed in the beginning. By doing some research, surveys and interviews the ground was established for further work.

This thesis aims at determining the heat losses in a property vent stack and its roof valve. Upon request of a company, the vent stack is analysed for possible heat recovering solutions to be implemented, while relining of the drain system is executed and with a suitable payback time for the economic investments. The heat loss calculations are based on data for properties that are located in the Stockholm region, but also easy to change depending on the situation. The calculations are done on pipes made out of cast iron, which still is the most common type of drain pipe in Sweden, and these are the pipes that relining is usually made on. The calculations that needed to take several variables into account have been done in MatlabR2014a and the thermos dynamical properties that were used in those calculations have been extracted from EES.Three different types of heat losses in the vent stack have been taken into consideration in this thesis.

?African Solutions to African Problems? är en av Afrikanska Unionens nya ledord. Denna vilja om att ta mer ansvar för den afrikanska kontinenten och kunna agera som en säkerhetsaktör har resulterat i en ny säkerhetsdoktrin. För att kunna agera som aktör på den internationella arenan krävs att vissa förutsättningar existerar enligt en modell framtagen av Gunnar Sjöstedt. Dessa strukturella och institutionella förutsättningar kommer i denna studie att undersökas för att analysera huruvida AU kan agera som säkerhetsaktör.

The purpose of this study is to see how preschool teachers are working with supportive signs and if it is a working tool for children's language development. Is the supportive signing just for kids with special need for support or can it be good for all children?I've done the study by interviewing preschool teachers that is working with supportive signs in preschool. I also had a questionnaire for parents that yielded less fruitful results. I have chosen to use children's language and constructivist and socio-cultural theories.What I came up with is that the supportive signs are very helpful in preschools, but it requires a lot from the one doing it.

This report will outline a proposal for the improvement of the baggage sorting facility at Arlanda airport. Swedavia is a state owned company group that operates, owns and develops airports in Sweden. One of their main roles is to create accessibility needed to facilitate and streamline the work at the airport.Swedavia is constantly working to develop new solutions and enhancements that will help to standardize and automate the work at airports without major impact on climate and above all adapt these solutions to work.The project has been aimed to identify and isolate the problem at the check-in counter, investigate the possibility of setting a speed control on the DC motor driving the luggage conveyer belt at the check-in desk so that the luggage does not lose tracking already there, as well as evaluate the new sorting systems planned to be introduce in the upcoming refurbishment of the sorting area.To determine the parameters that are used to regulate the speed of the baggage conveyor belt, information about the inputs and outputs that participated in the process was gathered. Information was collected both practically and theoretically. Process was followed and monitored by the supervisor of the company, and a theoretical study was done separately on my own.

AbstractThe tests work is about the subject "synergism of steel and concrete."The construction sector is in a strong competition and the different companies in the PrefabMarket has ever tried to develop new design solutions that are efficient and environmentallyfriendly.The purpose of this report is to highlight different aspects of interaction and size up a columndimension and to examine its efficiency and load capacity as Eurocode 3 and Eurocode 4. A sizing chart that describes the relationship between the torque and normal force shouldalso be made of the interaction . .

An increase interest of new methods and tools has begun to grow in the real estate business, this new trend causes an increase in new programs that aim to simplify processes of energy-efficiency and environmental issues.After consulting with Björn Alsmark from Bjerking AB, an architect and engineering company, we made a decision that the Degree Project is going to examine the program IES (Integrated Environmental Solutions) with some integrations from Revit Architecture application.To be able to examine IES, we got access to a completed project from Bjerking. The project is a nursery school in Uppsala. An application has been handed in from Bjerking to make this project to a Green Building-certificated project. According to Bjerking own calculations (with the energy-calculation program Enorm), the consumption of energy of the nursery school is 48 percent lesser than required by BBR.An evaluation of IES and Enorm has been made with an aim to compare these two programs and find out if IES is an appropriate program to replace Enorm. Does Enorm or IES come up to BBR´s recommendations?The Degree Project cover 15 ECT, that required several adjusting and delimitations, and the study sketch ended with a literature study.After finishing the study sketch the modeling of the nursery school began.

The report presents a thesis carried out on behalf of the company SAAB Training and Simulation which is situated in Huskvarna. The authors of this report are going to graduate as mechanical engineers focusing on product development and design, and this thesis should reflect the knowledge obtained during the education. The assignment, given from the company was to develop a concept of a stand that will constitute as a part of a mobile system for target practice. The reader get to follow throughout the project and can hopefully learn from the smart solutions and approaches that have arisen during the process.Today SAAB doesn?t have a mobile application in their portfolio that utilizes the benefits of their sensor measuring system, also called the LOMAH-bar.

As a newly graduated student in construction you rarely have as much knowledge as you wish you had. It is a complicated line of business that requires knowledge and understanding of both technical solutions and interaction between actors. It is impossible to be fully learned and with that much unknown it can be hard to know where to start. This report is one step in the right direction. It contains a planning that contains construction and installations for a one level house in Kiruna with its different choices motivated.

The Brussels I-Regulation, often referred to as the Jurisdiction Regulation, is said to be the matrix of the European judicial cooperation system within the area of international private law. The Regulation states how jurisdiction is to be determined in an international dispute. The aim of the Regulation is to ensure that parties in a dispute within the EU have access to justice.The Regulation is considered to be working well in general, and have been since it came in-to force in 2007. Although it is held to be well functioning it does not exclude that some improvements might be needed. The commission ordered a review of the Regulation and the result was that some deficiencies were identified.
