The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.

In motorsports competition, safety reasons require that the vehicle is equipped with some form of protective roll cage. The roll cage should withstand the forces involved in a collision to protect the driver and the co-driver from the vehicle body deformation. The roll cage also works to protect the vehicle from excessive deformations to more easily make any repairs afterwards. For the roll cage to be certified and approved for motorsports competition, it requires that the cage is built after one of the recommended options. One of those options is to design the roll cage like a cross-construction at the driver and co-driver doors.

Detta examensarbete beskriver processen för framtagandet av en ny design för det befintliga schemaläggningssystemet för räddningstjänsten. Ett av problemen med att schemalägga för personalen inom räddningstjänsten är att det är flera faktorer som måste tas hänsyn till. Några av dessa faktorer är vilken station de arbetar på, personalens kompetens, att det ska finnas personal på stationerna och arbetsroller. Syftet med examensarbetet var att skapa en ny design som uppskattas av de som arbetar med systemet. För att uppnå detta var de som schemalägger med och påverkade designen av systemet tidigt i designprocessen.Detta examensarbete innefattar en litteraturstudie, en förstudie, en intervjustudie, en fokusgrupp och två användartester.

This is a thesis about design of young stands of trees. A big source of inspiration has been Västerskog and Tor Nitzelius Park in Alnarp which both consists of a structure of squares. I wanted to examine if this type of planting could be valuable from an aesthetic and recreational point of view. One problem today is that many people believe that we have to wait for decades for a planting to grow up so that we can enjoy the ?ready result?.

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

The landscape is a great asset for Göteborg as a city and places in the landscape are much used by the public. This diploma work deals with the question of how nature in Göteborg can become more accessible and how a place in it can be supplemented with new landscape elements. It is a proposal for a new urban park at Björlanda peninsula in the western part of Hisingen, Göteborg, which today belongs to the Swedish Armed Forces and is a part of the Nature-2000 area "Nordre älvs estuarium". The reason for choosing this place is that it is the only area around the costal area in Göteborg that has not been built on and that it contains a very varied landscape. The proposal is presented as three different broschures, dated 10-20 years ahead: A map of a possible system of urban parks including a detail of such a park, Västra Hisingen (the western parts of Hisingen) The idea with a system of urban parks is to make the landscape generally more accessible and maybe open it for people that do not use it today. A broschure of the central area Välkommen, with my design proposal for an urban park at Björlanda peninsula The design aims to utilize the landscape elements water, mountains, vegetation and sky and to intensify the experience of them. A flora for Välkommen that shows a selection of plants for the design proposal.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Our time is characterized by the development of new technologies that facilitate communication between people. The need for Video Mediated Communication (VMC) is increasing because people move to other locations due to migration and global mobility. VMC provides the opportunity for millions of people around the world to ?hang out? and see each other despite the distance in between. The world is "shrinking" because of the Internet and our perception of distance is changing.VMC is becoming increasingly available, in the form of applications like Skype and MSN for mobile phones and computers, and in addition, it?s practically free.The purpose of this thesis is to render a picture of the way in which people use Skype in the private sphere.

BAKGRUNDEN OCH PROBLEMDISKUSSION: Design som företeelse har fått alltstörre betydelse för näringslivet och samhället i helhet. Allt fler företag inser designenspositiva inverkan på verksamheten och väljer att arbeta medvetet med det. I samband med attbyggnader ökar kraven på designens funktion, räcker estetiken inte längre, designen måsteprestera mer och visa att den är praktisk och effektiv att tillföra i en byggnad. Designassocieras ofta med stora kostnader men vilka positiva värdeeffekter skapar designen igengäld?SYFTE: Syftet med denna uppsats är att beskriva de värden design kan framkalla i enbyggnad, samt att försöka förklara sambandet mellan betraktaren och vilka värden den villframhäva i design.

In this essay we have approached the problem with retailer brands that copy marketing leaders to get consumers attention in the storeshelf. We have sought to explore how much a designed package would change the consumers opinion of a brand and if this effect is different depending on if the brand is a retailer brand or a market leader. Also we sought to find if this effect would be greater with a salient color on the package. We made a quantitative study and with regression analysis we found that a designed package did have effect on the consumers opinion of the brand, and that the design with the salient color made the biggest effect..

Through wing pattern, posture and movement, a harmless moth of the family Brenthia imitates an eight-eyed jumping spider. When an octopus of the species Thaumoctopus mimicus sense danger it can alter its appearance to that of a venomous sea snake. They are both drawing attention to themselves. Nevertheless, and because of this, they are protected. The mechanism is called mimicry.

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.

The aim of this paper is to examine how gender roles are described in two children's books and compare the results against the curriculum Lgr11 's values. The compared books have different aims though one of the analyzed books claimed to go against the gender roles and the other one isn?t. The method of analysis is discourse analysis and deconstruction of the text by using Nikolajeva´s (2004) pattern for stereotype gender descriptions and Kåreland´s (2005) analysis of story actions based on gender representations in children's literature. The analysis of the texts shows that there are differences between how the two books characters are described depending on gender. What emerges is that in one of the books femininity is valued high but instead it lacks equality between the sexes, while in the second book the main characters are described as equal even though the other characters are described in a stereotypical way.
