Utvärdering av laddningskoncept för lastbilsbatterier

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

Effektivisering av produktionsgrupp : Improving the efficiency of a production group

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

LEAD-arbete hos Lantmännen : En studie om arbetssätt för ständiga förbättringar inom en nordisk koncern

I denna uppsats ämnar författarna genom en fallstudie beskriva, förklara och analysera ett företagsanpassat internt system för ständiga förbättringar som utvecklats med hjälp av etablerade teorier. Det interna arbetssättet LEAD står för lärande och engagemang av medarbetare och analys och standardisering av förbättringsåtgärder. Studien syftar vidare redogöra för de grundläggade värderingar som ingår i det interna arbetsystemet och har genomförts via analys av den interna arbetsmetoden med hjälp av den generella teorin om den offensiva kvalitetsutvecklingen. Studien visar att det interna arbetssättet förhåller sig positivt till den generella teorin men är inte en unik metod vid förbättringsarbete. Vidare visar resultatet att LEAD inte förhåller sig positivt till alla hörnstenar inom teorin om den offensiva kvalitetsutvecklingen..

Att reducera ledtiden i en produktion med hög variation och låg volym - En casestudie på Lab.gruppen

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

Framtagning av kontrollmätningstekniker för byggnader genom en lead user-studie

TeliaSonera har sedan ett tag tillbaka inlett ett projekt med ett antal företag inom byggbranschen. Projektet går ut på att ta fram kontrolltekniker som kontinuerligt mäter en byggnads tillstånd genom hela dess livstid, så att eventuella brister kan upptäckas innan de blir till ett problem. Med andra ord är tanken att ha någon form av teknik som kontinuerligt avläser diverse egenskaper i en byggnad som exempelvis fuktighetshalten i väggarna, om ventilationen fungerar som den ska och halten av olika ämnen i luften.Det praktiska syftet var att verifiera om trenden kontinuerlig kontrollmätning efterfrågas genom att ta kontakt med branschexperter inom såväl byggbranschen som vissa andra parallella branscher och se om även de uppmärksammat denna. Under antagandet att de gjort det, var intentionen vidare att försöka urskilja de så kallade lead users. Lead users är användare vilka erfar behov före marknaden som helhet samt som är benägna till att vara innovativa, då en lösning på deras behov förväntas medföra stor nytta för dem.

Ledtidsreducering ur ett värdeflödes-perspektiv

This case study is performed within the production of Sherwin-Williams, Bellö. The purpose is to increase the understanding how a value stream can function more efficient, from a lead time perspective. With the analytical model that is build up on known theories, the purpose have been fulfilled. Mapping of value and non value time for four products thru their respectively process reveals wastes, which is, waiting, transport and movement, incorrect processing and set-up time that in it self create transport and movement. Thru identified wastes that causes loss in lead time suggestions of improvement has been proposed.

Piratkopiering: en ekonomisk-teoretisk granskning av marknaden för dataspel

This essay analyzes the market for entertainment software by identifying and explain the products typical properties, in addition i clarifies the behavior of consumers and producers. One of the most important property related to software is the ease with which it can be reproduced. When such reproduction is done illicit it´s called piracy. The software industry often claims that piracy leads to big losses for the companies as well as in welfare, the essay clarifies that this doesn´t has to be the case. On the contrary the possibility to cheap production and distribution may lead to an increased welfare.

Trimning av lead och lag filter

The work describes the development of an adjustment algorithm that will replace today?s manual adjustment of Lead- and Lag-filters at ABB Robotics industrial robots. The adjustment is mainly for the filter parameters in the control system.Three different algorithms have been created to replace the manual adjustment. One of them is based on the criterion from the manual adjustment and another one on optimization of the sensitivity function. The last one is a combination of the two.The report describe the development of the algorithms and how they behave during simulations and tests on real robots.

Konsten att förutspå konjunkturen - Hur användbara är enkätbaserade snabbindikatorer?

Foreseeing future changes in economic activity is of up most importance to a wide array of actors. The time lag in the presentation of official GDP statistics means that to somewhat accurately capture a tendency of where the business cycle is heading one need turn to qualitative sentiment indicators such as Purchasing Managers? Index (PMI) and official sentiment indicators for valuable clues. This thesis uses in-sample and out-of-sample methods to evaluate how well PMI and official Business Tendency Surveys (BTS) in Sweden and Denmark fair against the year-on-year growth rate of industrial production. Moreover, various Swedish regional sentiment indicators get examined and a case study of the indicator for the Öresund region is performed.

Banktjänstemäns uppfattningar om vad revisorer ska göra

The aim of the study is to describe and analyze bank officials' views about what auditors will do. The main motivation comes from the government?s proposals that the audit duty will be abolished and it can lead to that bank officials in a bigger extent can influence the audit?s formulation. It can also lead to that a consumer audit becomes reality. The study covers a sample of 302 bank officials where 153 have participated through a survey questionnaire.

SEM/EDS-analyser av föremål påträffade i Birka : En jämförande studie

The purpose of this paper was to identify the elements and the alloys that five objects found in Birka consist of and to examine whether there are any significant differences between the presumably imported and domestic objects. The material was analyzed using a scanning electron microscope (SEM) which was equipped with an energy dispersive X-ray spectrometer (EDS) in order to identify the elements that are present and the alloys that the objects are made of. Then the SEM results were compared with the results of previous analyzes that have been performed on finds from Birka in order to investigate how the objects differ in elemental composition and to find out if there are any significant differences between them. The results showed that the objects? content of the elements analyzed varies as the copper alloys the objects are made of.
