Kustnära ekosystem som skydd mot naturkatastrofer : en litteraturstudie från ett riskhanteringsperspektiv
Research suggests that society's vulnerability to natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..
Lane Keeping Aid : ett förarstödjande system för bilar
Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.
Lyfta Lätt Tekniskt hjälpmedel för pakethantering
People working with handling parcels in terminals are often victims of musculoskeletal injuries. This is largely due to the hazardous lifting of too many parcels which are too heavy and unsuitable work postures. The human body?s ability to lift and grasp objects is so outstanding that developing a device with the same capability is very difficult.The goal of the project has been to develop a technical device that will improve the handling of parcels with regard to ergonomics. The area of concern was the lifting of parcels between the conveyor belt and the cargo space of the freight car.

Design och Kalibrering av mätrigg för Poly-V remmar
Scania är en av världens största tillverkare av lastbilar, bussar och marina motorer och examensarbetet har utförts i syfte att utveckla en ny remmätrigg för att bättre kunna verifiera slitage, livslängd och töjning efter olika testcykler på Poly-V remmar. Riggen skall utföra mätningar enligt standard SAE-J1459 och klara att mäta remlängder mellan 1000-3300 mm. Därtill måste konstruktionen vara utformad enligt gällande säkerhetsföreskrifter och ergonomiska aspekter beaktas.Mätningar av Poly-V remmar sker efter principen att remmen spänns in mellan två remskivor med en kraft på 100 N per ribba.Vid examensarbetets start fanns en äldre mätrigg att tillgå, vilken inte längre är i bruk p.g.a. att den inte uppfyller alla krav för mätprocessen. Den har dock använts i syfte för att identifiera ergonomi- och säkerhetsrisker.
Inredningskoncept för vägambulans : Ett examensarbete vid Industridesignprogrammet 2011
The subject of this bachelors degree project is an interior layout for road ambulances.Landstinget Västernorrland (LVN) wanted a layout concept that would be used to com- municate their design intentions to the ambulance producers during their purchase process.Designing ambulance interiors is an extremely complex process since there so many fac- tors to take into consideration. It ?s not just about taking the equipment and place it where there is space left in the cabin. You have to start with the user in focus and the tasks that are to be performed in the ambulance environment.It ishard to find design solutions that will fit 100% of the ambulance personnel?s working routines for 100% of the tasks.
Konceptstudie av en kompakt Picker robot
Picker robots are often mounted close to each other above a conveyor belt. To be able topack robots even closer, it is desirable to reduce the footprint of the robot?s base. One way toachieve this is to skew the arms of the robot which makes it possible to move them closer toeach other.This Master Thesis has been carried out at ABB Corporate Research. The purpose is toevaluate the benefits and drawbacks for the idea of making today?s Picker robot morecompact by skewing the arms.
Modellering och styrning av flis till en sulfatkokare
At the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.
Att lyckas med en kvalitetsförändring : En fallstudie på OCS i Borås
Change is a natural state for both people and institutions, but as the surrounding world moves faster it becomes important to quickly be able to adjust to new conditions. Customers? force of negotiation increases as the global competition grows. One factor that becomes more vital to customers is the amount of quality standard a company can offer them. Several factors are essential if a work of change will be considered a successful investment, where the change can be perceived in both a positive and negative way for an employee.
Jämförelse av fyra rundbalspressars packningsförmåga som funktion av grödans torrsubstanshalt :
To succeed, and make money at your animal production you need to feed your animals with
high quality fodder. Other condition to succeed is that you keep your production costs at a minimum. To be able to produce baled silage at a low cost it?s very important that the bales have a high density. Density is measured in kg dry matter (DM) per cubic meter.
The purpose with this report was to learn more about making silage in round bales and to how much the bale density varies between different brands of round balers.

Design and evaluation of an AGV-system for Tetra Pack in Lund using simulation
This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.
