This report contains a degree project made by the mechanical engineering students Lennart Andersson and Daniel Jansson. The project has performed in assignment by SOMAS Valves AB in Säffle. SOMAS are leading in development on control and on/off valves. To maintain this position they always want to improve their products. One way in this development is valves that are more tightened.The purpose with our project was to investigate another seat design on a HiCo (High Cobalt Alloy) seat to a SKV 150 PN 25 valve and compare this to an original HiCo seat.By modifying the seat on a ball valve we want to achieve a valve that leaks lesser then a valve whit original seat.

Occupational Health Service (OHS) has an important role in society. It is designed to prevent illness and strengthen the health of workers. OHS operations and development are currently being studied at the School of Technology and Health at the Royal Institute of Technology in Sweden. One of the industries studied is the home maker service. During the 2010s were such employees one of the most ill groups in Sweden.This master's thesis in occupational environment development and change management focus on examining the special knowledge an OHS and its clients in one home maker service need to strengthen the workers of the industry and find out how the interaction between OHS and home maker service works and how it could be evolved.A qualitative study was conducted in a Swedish city on the basis of an organizational perspective.

Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

This degree project has been carried out by Carolina Rapp and Jenny Tauson, students at Innovation and Design Engineer program at the Faculty of Technology and science at Karlstad University. The project was carried during Spring of 2009 and took 15 weeks of full time work.  Doppelmayr/Garaventa Group is an Austria/Switzerland corporate group and its associated company Doppelmayr Scandinavia lies in Sunne, Sweden. Doppelmayr/Garaventa Group is the world quality and technology leader in ropeway engineering. The degree project goal was to develop a new shaping of a surface lift. There are two kinds of surface lifts, platter and T-bars. The two kinds of surface lifts have some variation in design but only minor differences.

During its lifetime, a road goes through a number of different stages; pre-study,inquiry of the road, work plan, documenting stage, building stage and operatingstage. The operating stage is the one that takes the longest time and costs themost. Those have a tendency of becoming unnecessarily high because the projectengineers don?t always take the management and maintenance prerequisites intoconditions.To decrease the management and maintenance costs, the Swedish RoadAdministration SouthEast has been in need of a work procedure that makes theroaddesign engineers take the management and maintenance of the road intoconsideration. This shall be achieved by a checklist where the most commondesigns that lead to increased management- and maintenance costs are compiledand listed.Through interviews with project leaders in management, the most commonproblems have been identified, analyzed and summarized under the headlineswinter-road, vegetation, road equipment and road designs.To elucidate the problem from several points of view, interviews wereimplemented with project leaders in investment and roaddesign engineers.

This report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage.

Examensarbetet behandlar utvecklingen av en bio- och spelsoffa med målet att ge soffan ett skandinaviskt utseende samt att soffan skall kunna anpassas efter användaren. Examensarbetet har utförts i samarbete med företaget EM Home och behandlar arbetsgången från förstudie till ett slutgiltigt koncept under lanseringsnamnet Vegas. Under  förstudien  gjordes  studier  av  marknaden  och  intervjuer  med  potentiella  användare. Detta gav en inblick i nuvarande sofftrender och en uppfattning kring vad användaren har för krav och önskemål på en soffa. En intervju gjordes även med forskare som studerar hur an-vändare av tv-spel agerar och genom dessa studier lagt märke till saker som användarna själva inte tänker på vilket gav en ökad förståelse för den verkliga situationen.

The report is part of the university´engineer program within Industrial Organization and Economics with specialization in Logistics and Managment at Jönköping´s university.Skoghall´s mill underlies a large supply chain, which means there should be a lot of areas in need of small improvement measures. This report illustrates a small part of one of these areas and is focused on the loading distribution services in the terminal Vänern.At the moment there´s a very unequal load of the load carriers SECU box and Container at the terminal. Skoghall´s mill has the desire to equalize the high and low load levels of the 2 loading carriers named previously. One of the options to solve the problem is to set a limit of how much the carriers can load per week or per day. The mill also wants it to be investigated if the proposition would influence the customers in any way and if both the company and its customers could handle a lower level of delivery services in case the proposition was to be applied.The goal to be achieved with this thesis is to provide balance to the unequall loading of the 2 load carriers, SECU and Container, and investigate whether or not the Skoghall´s mill´s customers, could manage the lower degree of delivery service that the proposition would imply.For this goal to be achieved, random sample investigations were taken from orders of a customer that is provided with SECU load carriers and the same was made with a Container´s customer.

Abilia utvecklar, tillverkar och säljer tekniska hjälpmedel till personer som antingen har en fysisk eller psykisk begränsning som påverkar deras vardag. För att dra ner på kostnaderna och få en bättre enhetlighet vill Abilia att ytterförpackningarna ska standardiseras samt att ett flexibelt inrede som ska kunna anpassas till många av företagets produkter utvecklas.En förstudie lade grunden för projektet där många olika områden och metoder undersöktes. De existerade förpackningarna utvärderades, deras och produkternas livscykel kartlades varpå det framgick vilka som var projektets huvudanvändare. Dessa intervjuades och en kravspecifikation kunde sedan fastställas. Förstudien resulterade i att det fanns två grupper av produkter som lösningen måste kunna anpassas till.

In a global economy it is important to understand what project management is and how it functions in a contemporary company. This report includes an empirical case study of a project flow, which was conducted in the department Packaging Concept (PC) which is a part of Stora Enso. As all of PC´s customer enquiries are unique and must be considered an individual project, PC continuously works in projects. An analysis of the project flow was conducted based on interviews at and visits to PC as well as relevant documents distributed by the department. The report gives an understanding and analysis of how PC works in projects.

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

SOMAS är ett tillverkningsföretag i ventilbranschen som tillverkar olika sorters ventiler och ställdon.SOMAS vill konstruera en kulventil med en genomloppsdiameter i den standardiserade dimensionen DN500 för att kunna möta kundernas önskemål. Som konstruktionen ser ut idag kommer den bli för stora moment för ställdonen att manövrera kulan om man skalar upp en DN400 kulventil till DN500, varför ny konstruktion behövs.Syftet med projektet är att komma med idéer till konstruktionslösningar samt att utreda vilken av dessa som i slutänden är den mest lämpliga.Målet är sedan att ta fram ett konstruktionsförslag på det mest lämpliga förslaget.3D CAD-modeller gjordes av SOMAS befintliga DN400 kulventil, i Pro/engineer var det sedan lätt att se vilka skillnader på kulans massa de olika modifieringarna gjorde.Vi modellerade den befintliga DN400 kulan, kula med kapad botten och tärningsform. När massan på de olika alternativen och gjutgodsets kilopris var känd kunde vi sedan räkna fram prisskillnader i procent mellan de olika alternativen.Vi tittade på olika typer av lagringar och delningar av ventilhusen, både med lösa och fasta spindlar.Tittade på alternativa tillverkningsmetoder och alternativa material för kulan. Priset på de alternativa materialen jämfördes med standard gjutgods (SS 2343).För att få fram storleken på ett säte till en DN500 kulventil gjordes beräkningar på sätestrycket. Ett diagram skapades i Excel över alla SOMAS kulventiler för att få fram ett erforderligt stängningsmoment för en flytande DN500 kula (flytande innebär att kulan inte har någon lagring i botten, se figur 2 sid.

Denna rapport är en examensarbetsavhandling utförd vid KTH, Kungliga Tekniska Högskolan, under mars-augusti 2013. Arbetet har gjorts i samarbete med Nexus Marine som är en ledande tillverkare av marin navigationsutrustning för segelbåtar.Syftet med examensarbetet var att utveckla en ny konstruktionslösning för en vattentät kapsling till företagets instrument. Kapslingen skulle gå att öppna och stänga och skruv eller lim skulle inte användas i konstruktionen. Arbetet innefattade inte kapslingens yttre design som skall utföras i ett senare skede. Kapslingen skulle uppfylla de krav som finns uppställda för klassningen IPX7.Nexus Marines navigationssystem och nuvarande sortiment studerades för att ge en bild av vilka funktioner som kapslingen skulle innefatta och i vilken miljö den skulle användas.

Transportation of oil and gas by the Sea characterizes challenges from a safety viewpoint. In this type of transportation, different sizes of special tankers carrying oil and gas. The marine transportation of these scarce natural riches is involved with risks and hazards, which may lead to many losses; for instance, wasting oil and gas, injuries of people, damaging ships and properties, and damaging environment. The main purpose of this thesis is to evaluate the risks, hazards, and accidents during transportation of oil and gas (mainly Crude Oil, liquefied petroleum gas, and Liquefied natural gas) by the Sea with concentrating on transport safety. Hence, a better understanding of these risks and hazards can contribute to decrease of addressed losses.This study is carried out on risks associated with maritime transportation of oil and gas starting with describing the general casual chain (dealing with causes, incidents, accidents and consequences/causalities), continuing with describing risk analysis techniques (including event tree analysis and fault tree analysis) and risk control measures/options, and finally implementing aforesaid investigations on real data from two areas; namely UK territorial waters and the Baltic Sea.In this study, the results of analyzing data from 1991 to 2010 in UK territorial waters revealed that collision and grounding were two most common accidents in terms of crude oil tankers, LPG and LNG carriers in which 44% of all accidents were equally divided between collision and grounding.
