Analys av tidsåtgång vid montering av aggregat på Haldex Barnes Hydraules

Haldex Barnes Hydraulics (HBH) is a company which produces hydraulic aggregates for use in forklifts, construction equipment, and trucks. The last two years the company has expanded. This has lead to an insufficient production of aggregates. Thus wishes HBH to increase their production without making to large investments.This report includes a now-state analysis of the problems and where they are. From this a further analysis of possible improvements are made.HBH works mainly with assembling and this is made manually.

Byggnadslogistiskt arbete för minskat slöseri ? En studie över arbetsfördelningen vid innerväggsmontage på Tuve Bygg AB:s projekt Stapelbädden etapp 3

The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

Utveckling av en äldre villaträdgård : från oplanerad till planerad

The result of this work is a plan for the development of an 1128 m2 elderly raised garden. The purpose has been to create an overall plan covering the long-term development of the garden. The work process has covered a description of the garden of today, review of requirements, analysis of the garden sections, design of a new plan as well as starting the construction of the new garden. The plan covers a time period of a couple of years to create the new garden since the construction work is carried out during spare time with small resources available. The planning must contain review of functions such as protection from insight, eating area and compost area. Also the esthetic expression must be planned. Colors, shapes, choice of material and plants together make up the esthetic expression. It is recommended to include anything you wish to create in the garden. In a raised garden one has to overcome the step to remove trees and shrubs and think different.

Andra företag har implementerat förbättringsprogrammet Sex Sigma och en undersökning av dess lämplighet för Sandvik Materials Technology bör ske. Arbetet syftar till att undersöka förbättringsprogrammet Sex Sigmas utrymme inom det interna förbättringsprogrammet Lyftet Ledtid. Det bör även ange hur en eventuell implementering kan ske.

Överföring av och beräkning med timmätta värden ? från MT2000 till Xpower

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

Virtuell community i mobilen - Kriterier som ligger till grund för en framgångsrik virtuell community i mobilen

Sociala nätverk tar stor plats på Internet genom virtuella communities. Användare har en större möjlighet att nå dem via mobila lösningar och därmed göra dem till mobila communities. Kriterierna som ligger till grund för framgång för virtuella communitiesvill vi applicera på mobila communities. För att undersöka dessa kriterier, och bakomliggande faktorer, har vi valt att titta på ?tidigt bruk? användning av en mobil community, Facebooks mobila portal med hjälp av Technology Acceptance Model (TAM).

Skillnader mellan uppkopplad och uppkopplad : En jämförelsestudie mellan 1960- och 1990-talister

This paper aims to examine whether there are any substantial differences between a generation of users born during the 1960?s and younger generation born during the 1990?s regarding the use of digital technologies connected to the Internet. Based on Marc Prensky?s theories on people born before and after 1980 saying those born before are not as natural when it comes to using digital technologies. We used diaries as a qualitative method to gather data from 16 respondents.

Den dolda genusordningen på museer. En studie kring museers arbete utifrån genusperspektiv.

SammanfattningMuseer har till uppgift att dokumentera, forska och samla in människans och naturens lämningar för att berika kulturarvet och bidra med ny kunskap. Frågan är vad det är för kunskap som förmedlas och vad det är som väljs att ta med i kulturarvet. Denna uppsats syftar till att lyfta fram diskussionen kring huruvida kulturarvet och kunskapsförmedlingen är könsneutral och hur den dolda genuskonstruktionen speglas i utställningarna samt att studera hur ett genusperspektiv används och integreras på Tekniska Museet i Stockholm och Malmö Museer. Som empiriskt underlag ligger kvalitativa intervjuer med sammanlagt 8 representanter från båda museerna. Den teoretiska basen består av teorier kring kultur, kulturarv och genus.

Kostnadsutveckling i anläggningsprojekt. En studie av processen före byggstart i två vägprojekt.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Förbränningslära för bubblandefluidbädd

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

Framställningar av tiggare & tiggeri. : En kvalitativ text- och innehållsanalys av debattartiklar i Dagens Nyheters mellan 3 september 2010 och 24 februari 2014.

The aim with this study was to analyze and understand how begging is constructed as a social problem in Sweden between September of 2010 and the end of February in 2014 in debate articles in Dagens Nyheter. To do this I have chosen to use a social problems theory and critical discourse analysis to highlight some aspects in the process of defining the social problem. The study's main finding is that the construction of beggars and begging appears to be in a relatively extensive redefinition in the current situation. It is shown by, for example, a shift in focus in the discourse. For this reason, it is relevant for social work to examine how the construction progresses..

Låt den rätte komma in - En studie om valet av vd i entreprenörsföretag

Entrepreneurship is said to be the missing link between knowledge and growth in the Swedish economy. New ventures run a high risk of failing and this holds true especially for technology ventures. Since company leaders have proven to exert an influence on organisations' survival possibilities, the selection of an appropriate CEO is important. The purpose of this study is to describe the importance of the CEO for ventures as well as to explain how knowledge and experience affect the opinion of who should be CEO. Using a qualitative case study research design including three life science companies, we show that there are three main factors crucial when selecting a CEO.

Planering, förutsättningar ocheffekter av implementering avsolceller i stadsutvecklingsprojekt.

Today, buildings utilize 40 % of the total energy consumption. New energyrestrictions and directives have entered the construction industry. Photovoltaic is asustainable, clean and quiet solution that integrates well in the urban environment buthave not yet reached a breakthrough on the Swedish market. The conditions for solarenergy production are often set in the early planning stages where they rarely arebeing prioritized.This master of engineering project focuses on identifying problems regardingimplementation of photovoltaic in city development projects and giving suggestions topossible improvements in the planning- and construction process. It also givesrecommendations on how the conditions for energy production can be optimized inthe early zoning stage.By conducting simulations with PVsystV5.21, on three ongoing city developmentprojects in Umeå, Malmö and Stockholm and by carry out and analyzing interviewswith city planners, constructors and architects, some conclusions have been made.Several improvements, both politically, with changes in the subsidization systemand/or instatement of a new law with feed-in tariffs, and within the solar- andconstruction industry itself, with better communication between different parts of theprocess as well as better use of experience, can be made.

Tala eller tiga - En kvalitativ studie om självupplevelser av medierapportering
