Ställtidsreducering med hjälp av SMED i pressgjuterianläggningar

To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.

Är priset ett sätt att påverka mängd frukt och grönsaker i kosten?

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Is pricing a way to affect share of fruits and vegetables in a diet?Author: Maria PopovSupervisor: Heléne Bertéus ForslundExaminer: Ingrid LarssonProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2013Background: Fruits and vegetables (FV) are important for health, including occurrence of diabetes, obesity and cardiovascular diseases. Said diseases cause most cases of illness and death in high-income countries. Only a small part of the population achieves the FV-intake goal, so a higher FV-intake is desirable. Besides general information campaigns there is another method of influencing what people might buy.Objective: To examine whether different pricing is connected to FV-intake or ?purchase.Search strategy: Databases PubMed, Scopus and Summon were searched with ?vegetable consumption", "price/pricing policy" and "food choice? in different combinations.Selection criteria: Studies performed after year 2000 on at least 18 years old persons from North America, Europe or Australia, examining changes in FV-price and -purchase.

When Washington Take Over?An economic meltdown wreaks havoc on the world and has plunged the Western world into a spiral of economic stimulus in order to keep their way of life intact. At the same time the same institutions that support these countries have had another agenda for more unfortunate and less influential countries where nothing has been free and everything been to a price of self-sacrifice in order to get the consent of the IMF and the World Bank. Everything according to the points stated in the so called Washington Consensus.The purpose of this dissertation is to research what impact the Washington Consensus has on the state in terms of power over the market and sovereignty.

MÄTNING AV ANDNINGSMUSKELSTYRKA - JÄMFÖRELSE AV NORMALVÄRDEN MELLAN NY OCH BEFINTLIG UTRUSTNING

1 MÄTNING AV ANDNINGSMUSKELSTYRKA JÄMFÖRELSE AV NORMALVÄRDEN MELLAN NY OCH BEFINTLIG UTRUSTNING ELIN KELLERSSON Kellersson E, Jämförelse av andningsmuskelstyrke mätning på ny utrustning. Examensarbete i biomedicinsk laboratorievetenskap 15 poäng. Malmö högskola: Hälsa och Samhälle, enheten för biomedicinsk Laboratorievetenskap, 2012. Svaghet i andningsmuskulatur är vanligt hos neuromuskulärt sjuka, lungsjuka och hos vissa patienter som behandlas med steroider. Vid neuromuskulära sjukdomar utgör en progressiv försvagning av andningsmusklerna (främst diafragman) det allvarligaste hotet mot överlevnad. Andningsmuskelstyrkan kan mätas med hjälp av en spirometer, där det maximala inspiratoriska trycket (PI max) och det maximala exspiratoriska trycket (PE max) mäts med hjälp av tryckreceptorer vid en pnemotachograf.

Tystnad och Tillhörighet : berättelser om homosexualitet från 1980-talets Polen

There was a silence surrounding homosexuality in the People's Republic of Poland. One can almost get the impression that same sex love, and same sex relationships, did not even exist there; that the communists had successfully removed homosexuality from society. The roots of this silence can be found in the Communist Party´s disdain for anything deemed individualist and deviant, and also in the conservatism and religiosity of the Polish society.In my thesis I study when and how gays and lesbians found a way out of the silence that surrounded their sexuality. Gay men did so by creating subcultures, which found refuge in parks, public bathrooms and a few bars in larger Polish cities, and offered a sense of belonging for them. Lesbians, on the other hand, lacked this access to semi-public spheres, which made it even harder for them to find each other and create a space for their sexuality.

Redesign av reduktionsutrustning i asselvalsverk inom stålindustri : Ett examensarbete utfört på konstruktionsbyrån BEKAB mot stålindustriföretaget Ovako

Intresset för sömlösa stålrör med stora ytterdiametrar i förhållande till tunna väggtjocklekar har ökat tillsammans med att högre hållfasthet i olika stålsorter tillkommit. Detta gör det möjligt att tillverka lättare, billigare och mer materialeffektiva stålprodukter med samma eller högre hållfasthet som tidigare.Denna nya utvecklingsriktning medför förändringar och utmaningar i en av företaget Ovakos produktionslinor i Rörverk 5 Hofors, vilket de har behov av att samarbeta med maskinkonstruktionsföretaget BEKAB för att utvärdera och utveckla.I Ovakos produktionslina i Rörverk 5 finns en del av ett asselvalsverk som kallas för "förreducerare". Denna del av asselvalsverket ser Ovako ett stort intresse i att utvärdera och utveckla för att bättre anpassas till den nya utvecklingsriktningen.  En känd utmaning hos förreduceraren sen tidigare är att den från början är framtagen för att reducera ner ett kvalitetsproblem hos rörprodukterna som kallas för trattbildning. Projektet fördjupar sig därför inom trattbildning för att bättre förstå grunden till förreducerarens nuvarande design för att därefter genomföra en redesign av förreduceraren.I en nulägesanalys av nuvarande förreducerare framkommer ett flertal olika produktionsutrustningsproblem med tillhörande kvalitetsproblem hos rörprodukterna. Projektet väljer därmed att fokusera på de produktionsutrustningsproblem som ger störst effekt för förreduceraren om de löstes.

ALM - Tillgång/skuldmodell för riskberäkning och portföljoptimering

Asset management in insurance companies differs from conventional asset management to the extent that respect has to be taken to both assets and the commitments the insurance company has towards its customers. A model that has proven to fit well regarding the matching of assets and liabilities is the Asset Liability Management Model (ALM model). In addition to the matching in the balance sheet, the ALM model can be used in a company's work with strategic portfolio allocation by applying it as a basis for analyzing investment strategies with expected risk and return. From this, the ALM model also becomes relevant for calculating key figures according to the legal framework Solvens II which includes laws and regulations regarding the demands on economical strength (solvens) of insurance companies.Hence, the goal of this masters thesis has been to, on behalf of Bliwa Livförsäkring, create an ALM model to support the asset management department of Bliwa in their work with defining a credible way of analyzing the future risk and return of Bliwa's asset portfolio and insurance undertakings.The ALM model generally consist of four submodels, the scenario model, the liability model, the asset model and the company model, where the scenario model often is named as the core of the ALM model. The course of action has been to develop these submodels individually, with focus on the scenario model.

Hur simträning påverkar hundar

Hydrotherapy is a relatively new area when it comes to treatment and prevention of different problems in dogs, but an area that is growing in popularity. In Sweden, the person who performs hydrotherapy on dogs doesn?t need veterinary education, which is the case in some other countries. What makes hydrotherapy advantageous is that water has an ability to provide an environment where injured body parts can be supported, which means that rehabilitation can start early without the risk of affecting the injury and in the same time relieve the pain for the patient. There are only a few studies of hydrotherapy on dogs and these studies focus on the physical health of the dog.

Metodik för fastställande av bärförmåga på befintliga betongkonstruktioner

Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.

End of line test : En studie av företaget Emotrons linjetestning i produktionen

Emotron is a company specialised in developing, producing and marketing equipment to con-trol, monitor and protect processes and machinery driven by electric motors, with an applica-tion focus. Examples of uses for their products are fans, pumps, lifts and cranes.The project is to look at Emotrons end of line test. The company has seen that at the final test-ing there is a bottleneck that restricts the outflow and prevents an increase in the number of tested products.The purpose of this project is to review how Emotrons end-of-line test works today and if there is a possibility to make the test more efficient in such a way that the quality is not at risk, while increasing the outflow of tested products.The projects first step is to look at and analyse what is causing the bottleneck at the end-of-line. When the analysis is complete, the next step is to review whether there is a possibility to solve the bottleneck and if so in what way can this be done. Emotrons most overall objective of the project is to increase the outflow of the number of tested products without jeopardizing the quality.An analysis has been made on frequency inverters, soft starters and shaft power monitors.
