Landskapsplanering ur ett hållbarhetsperspektiv :
Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.
Informerar bredbandsleverantörer sina kunder om det ökade behovet av säkerhet?
Problemområde:
Fler och fler privatpersoner kopplar upp sig mot Internet via bredband. En
anledning till detta är att fastighetsbolagen allt oftare erbjuder sina
hyresgäster fast uppkoppling. Vad hyresgästerna kanske inte tänker på när de är
uppkopplade flera timmar i sträck, är att det är lättare för någon utomstående
att göra intrång i deras datorer.
Frågeställning:
1. Informerar bredbandsleverantörer sina kunder om risker för intrång?
2.
Rening av avloppsvatten efter skärprocess
ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB
Flexible Automation with high-pressure intensifier/pumping technology from
Ingersoll-Rand to provide and continue to develop innovative waterjet cutting
systems for global markets.
The purpose of this assignment is to develop a process water purifier. The
purifier should be applicable as an option to ABB I-R?s production cell
Cutting-Box.
At first hand the process water should be purified well enough to let out in
the municipal sewage system, but the ultimate solution is purifying the process
water to the range that recycling is possible.
When investigating the different principle of purifying water, a research of
different products and their manufactories was done.
These different products were compared and the principle of filtration was the
most applicable, as most of the products were designed for far larger
applications.
As the process water contains quite large amount of particles, it is necessary
to perform the filtration in different steps.
The process water purifier is therefore composed of a module of coarse
filtration and one of micro filtration.
In the module of coarse filtration the mainly amount of fibres and particles
are eliminated. They are kept back in the container unit with the larger
fragments and dumped with these when the container is emptied.
In the module of micro filtration the filtration is performed in two steps.
In the first step particles larger than 50?m are eliminated, in the second step
the micro filter is setting the range of purifying, in this case 10?m.
Rådgivning i AMS-besättningar : utvärdering av nyckeltal
Swedish dairy production has during the last decades undergone considerable structural rationalisation and the number of dairy herds has decreased to less than 7000. At the same time the average herd size has increased and a large proportion of those investing in new buildings today choose automatic milking (AM). During 2008 more than ten percent of the Swedish cows will be milked with AM. The development has been faster than expected and the need for consulting has increased rapidly. This study aims to evaluate whether a check list originating from the FRISKKO (?healthy cow?) programme can be a useful tool when assessing how well the herd functions in various areas.
Prototyputprovning av upphängningssystem
Examensarbetet gick ut på att stötprova ett system för upphängning av kablar
och rör i fartyg.
Vid stötprovningen monterades upphängningssystemet i en fixtur. Gruppen fick
fria händer att utforma fixturen. Med hjälp av Fredy Olssons teorier om
produktframtagning utvecklades en fixtur bestående av fyrkantrör.
Genom att värdera och selektera bland de lösningar som presenterades i
examensarbetet ?Upphängningssystem? BTH-IMA-EX?2000/C-02-SE och andra
nytillkomna likvärdiga lösningar, har gruppen kommit fram till och stötprovat
ett system, bestående av aluminiumprofiler och vinklar från Bosch Rexroth.
Pålade plattor för stora laster : En jämförelse mellan nätarmerade och fiberarmerade betong plattor
Funktionskraven på industrigolv har under senare år ökat. Ett industrigolv skall klara att överföra laster till underlaget samt utgöra ett fast och plant underlag. I denna rapport har två utföranden av påldäck för golv i lagerlokaler jämförts. Den traditionella metoden med armeringsnät har jämförts med en något nyare metod med stålfiberarmerad betong. Jämförelserna har gjorts under förutsättning att golvet skall belastas med 3 ton per kvadratmeter.
ERP-system : framgångsfaktorer vid införandet
Syftet med uppsatsen har varit att undersöka framgångsfaktorer vid införandet av ERP-system i olika företag. Både kundernas och leverantörens syn på framgångsfaktorer vid införandet har klargjorts. Min empiriska undersökning har utförts på fem olika företag och jag har intervjuat totalt fem personer som samtliga haft mycket centrala roller vid ERP-införandena. Vid intervjuerna har jag använt mig av kvalitativ ansats där informanterna har fått berätta relativt fritt om vad de uppfattat kunna påverka framgången med införandet av ERP-systemen. Jag analyserade det insamlade materialet med hjälp av empirinär kvalitativ bearbetning, i form av innehållsanalys.
Att sticka ut i mängden - En studie av tekniker för variation av instansierade modeller
Trots den senaste tidens hårdvaruutveckling är realtidsrendering av stora
folkmassor fortfarande ingen trivial uppgift. Denna uppgift beskrivs som crowd
rendering. Effektiv crowd rendering bygger ofta på instansiering, men
instansiering kommer med ett problem, det skapar kloner. Denna uppsats syftar
till att undersöka och utvärdera ett antal tekniker som används för att skapa
mångfald för instansierade modeller. Dessa tekniker kommer tillsammans att
kallas varierad instansiering.
Processutveckling av borstgradning
During the milling of Sandvik Coromant?s world leading Drill with replaceable inserts,the CoroDrill880©, burrs appear around the milled surfaces. The burrs are removedusing different methods, one of which is deburring with special brushing machines thatare integrated into milling cells. The machines of the type Sinjet, use a Siemensguidance system. The deburring results are not satisfying and manual deburring isrequired afterwards.
Utmaningar med utveckling av mobila applikationer : En fallstudie om kravhantering ur ett utvecklingsperspektiv
The use of mobile devices has during the last years expanded and on the market you can see a huge amount of applications. The development of mobile applications differs from traditional systems development since mobility infers that mobile applications can be used in different technological and social contexts. Although previous research has recognized that mobility can present mobile application developers with certain challenges, empirical studies of how problems arise and how they can be handled has thus far been limited. In this study we focused on the requirements engineering process from a development view with the purpose of finding challenges emerging in the development process. The study is based on a qualitative case study that employed semi-structured interviews with both project managers and system developers active in the requirements process.

Metod för att mäta förändring av city logistik : - En casestudie på Sandvikens kommun
To distribute goods to customers in urban areas is necessary to support the economic and social development in the cities, but has consequences that affect both residents of cities as well as the environment. The environmental effects of these types of transport involves not only the emissions of various pollutants, but also an increased noise level inside the cities. Many companies and organizations are working hard to change the distribution pattern to streamline transport in the urban area, while environmental impact is reduced. This is in line with what is called the City Logistics. The purpose of this thesis is to create a method for describing and measuring a given transport solution in order to compare it with an altered transport solution to achieve a more sustainable development.
