Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.

This is a thesis for a Bachelor Degree Project, performed in the subject MechanicalEngineering. The students Roger Malmberg and Simon Hagberg have carried out adesign project on behalf of the recently established company J&D Assisting systems,located in Halmstad.The project consisted in developing J&D's first prototype of a power assisting solutionfor wheelchairs. A power assisted wheelchair combines human power, which is deliveredby the arms through the pushrims, with electrical motors, which are powered by a battery.The power assisted wheelchair is aimed at customers, who have used a regularwheelchair for a long time, but who have become weaker or just need additional powerwhen driving uphill. This kind of wheelchair will provide additional power for users,which will spare their wrists, elbow and shoulders. The product is torque sensor free andinstead it relies on the velocity.

This study focuses on carpooling and how carpools can be better integrated into today's society.

With help from Hälsoteknikcentrum the need for storage of medical items in the home care section has come to our attention by an investigation that Hälsoteknikcentrum did. Facilea and the nursing stuff at Eketånga home care have developed a product specified to improve the work situation for both the nursing staffs and the patients.The trolley is equipped with a special module to make the trolley more adjustable for the recipients and the nursing staffs needs and desires. The product also collect all the care items in one place. Which gives the care patient and its relatives a possibility to gather all the medical items in one place and don?t have to put these in bookshelves etcetera.After surveys, interviews and home visits a prototype was built.

Intermodulated force microscope (ImAFM) is a type of dynamic AFM. ImAFM opens up possibilities for mapping the topography and making quantitative determinations of material parameters at the same time. With increased information the need to generate more informative images of the sample emerges. In this Bachelor's degree project I have created tools for rendering images of a sample. The topography is plotted as the height and a material parameter is color coded on topography.

Have you encountered problems when you are unlocking a door? Perhaps you have had your hands full when you needed to unlock the door? Or, you might be suffering from a disease and have difficulties to put force on to small objects. To solve these problems there are different options. The most common alternative is a key button. With the key button, you do not need turn the pinion to unlock.

Export is a top priority for Sweden's economy but for Swedish companies it may involve uncomfortable risks of exporting without sincere consideration. When the United Nations Security Council puts an embargo against a country, this often mean an import and export restriction. The thought is to push undemocratic regimes into respecting human rights. When the embargo is in force, however, the parties are not able to fulfill their contractual obligations, which practically means that the agreement will be suspended. The problem is what happens when an embargo is in force for a longer period of time.

This study describes how a larger investment by a private company in the northern interior can affect a municipality?s economy. The mobility to the municipality is expected to increase and some of the direct and indirect effects that this investment can implicate on their economy are discussed. The method for this study is qualitative. Interviews have been made with the initiative owner of the company LHG Learning Center and with civil servants in the municipality of Lycksele. The conclusions drawn in this study are that the establishment of LHG Learning Centers in Lycksele will include both opportunities and risks for the municipality?s future.

Målet med detta examensarbete är att minska risken för olyckor där grävmaskiner, med borr- eller pålmast monterad, är inblandade. För att kunna uppnå detta mål, har ett beräkningsprogram skapats som definierar ett säkert arbetsområde innan ostabilitet inträffar. Detta har gjorts genom att studera tidigare forskningsarbeten inom området samt verifiering av beräkningsprogrammet med hjälp av en fallstudie och data om maximal lyftkapacitet för grävmaskinen..

De flesta människor reser dagligen till arbete, skola eller för att uträtta ärenden, men dessvärre utgör sätten som vi reser på en belastning på miljön som inte är förenlig med en långsiktigt hållbar samhällsutveckling. I Sverige står transportsektorn för ungefär en fjärdedel av landets energianvändning och cirka 30 procent av landets totala klimatutsläpp. En stor del av utsläppen genereras av persontransporter och forskare menar att en minskad energianvändning genom ett smartare och mer hållbart resande är en viktig utveckling för att minska transportsektorns miljöpåverkan. Då arbetsrelaterade resor utgör hälften av alla persontransporter i Sverige, spelar företag en betydande roll, eftersom de har möjlighet att påverka både arbets- och tjänsteresor.Syftet med examensarbetet är att undersöka hur ett företag och arbetsplats, ÅF i Solna, kan skapa förutsättningar för hållbara arbets- och tjänsteresor. Vidare är syftet att ta fram åtgärdsförslag baserat på ÅF:s mål med att minska miljöpåverkan från resor.Mot bakgrund av utförda litteraturstudier, som redogör för bakgrunden till företags arbete för hållbara resor, som beskriver svenska arbetsmetoder för ändamålet och som diskuterar goda exempel på åtgärder som utförts av organisationer i Sverige, har en studie av platsförutsättningar och en resvaneundersökning genomförts på ÅF i Solna.

Abstract One of the essential conditions of the co-operating within the EU is that homogeneous conditions of competition prevail within the entire common market. The competition policy in the EU should guarantee that the competition is not distorted in a way that would prevent or create difficulties for the free mobility of goods and services between the member countries. The policy of competition should also guarantee that no new protectionistic obstacles will be formed, regardless of if it is being done by actions taken by member countries or as a result of actions taken by companies in order to set limits to the competition. Companies putting to an abuse their dominant position on the common market, or on a substantial part of it, is irreconcilable with the idea of the common market in case it could interfere with the trading between member countries, and is thus prohibited. The purpose of this dissertation is to describe the collective dominance from the view of the commission's interpretation of the practice of article 82 in the EG - treaty.

The object of this thesis is to discuss the limits of the hypertext concept. The issue is whether the concept of hypertext necessarily depends on the conditions of the electronic media and www, or if the concept of hypertext more likely is founded on certain textual structures and strategies. In the light of contributions to hypertext theory during the 1990s, this thesis compares different views on hypertext, and concludes with an evaluation. The poem it the authors own translation of the original Danish title det, written in 1969 by the system-poet Inger Christensen, is the object of this case study. The poem is analysed with respect to its structural organisation and literary composition.

The main objective of the essay is to define the meaning of the termgovernance network on the basis of democratic values ? both normative andimperial - with the aim to analyse the prospects to develop an effective anddemocratic governance. Democratic values as well as civil participation,enlightenment, responsibility and approachability are discussed, but also moreeffectivness orientated values.It is clear from the presentation how normative and democracy models putdifferent values in focus, with the consequence that other values are played downor pushed aside. Compared to imperial research in partnership ? by definition atype of network arrangement - and with a starting point in democracy andefficiency, the networks are discussed as political formation.In what sense can the actual existing network arrangements meet and fulfil thedefined political values? As no straight forward answer exists, there is an ongoingconflict between the political demand for slowness and the effectiveness demandfor flexibility and mobility..

In the assembly process of airframe structures there are many drilled holes and on some parts the holes are mainly drilled manually with pneumatic handheld drilling machines. During conventional drilling in metal, burrs appear. To remove these burrs the parts of the structure must be separated and deburred before they can be put together for fastening. This is a time consuming measure and therefore expensive. To facilitate this process and lower production costs some parts of the process needs to be automated.A part of this thesis was a project in co-operation with Saab, Novator, Specma Automation and the University of Linköping.
