Examensarbete : Implementering av

I denna rapport behandlas verktyget FMEA (Failure Mode Effect Analysis), dess användning och genomförande på identifierade komponenter som ingår i elmotorer tillverkade hos ABB LV Motors i Västerås. Målet med detta arbete har varit att ge lärdom om metoden FMEA på företaget för att möjliggöra användandet av verktyget bland medlemmarna på företaget och att vi implementerar verktyget på befintlig motor för att analysera de felsätt som kan uppstå. Eftersom ABB just nu har ett pågående projekt med en ny motor kan våra slutgiltiga felanalyser även ge dem information om vilka ändringar och åtgärder som kan vara till nytta vid utformningen av den nya motorn.Efter två veckors praktik i verkstan och en grundlig genomgång av företagets reklamationer kunde vi avgränsa arbetet genom att identifiera de komponenter som analyserna skulle genomföras på. Efter en genomgång tillsammans med våra handledare på företaget kom vi fram till att utföra våra analyser på fem komponenter, två av dem framstod som mycket kritiska som upptäcktes redan vid genomgång av reklamationerna.Komponenterna som vi har analyserat är:1. Lager2.

Implementation av ett interface till Emotiv Epoc

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Om du lyssnar på mig kanske jag lär mig något! : En essä om relationers betydelse för barnets lärande på förskolan

The purpose of this essay is to explore how educators are supposed to prioritize their work at the preschool so that all children are listened to and the conditions necessary for kids to dare to express their feelings and thoughts are in place. How is the relationship important for the child's learning? How do I become a committed educator who knows how to interpret and prioritize my work so it benefits children's learning? I am developing these questions in two parts in my following text. Firstly I am writing about why it is important that we who work as pedagogues meet the child on the child?s own terms.

Fortkörning - en inkomstfråga? : En studie utav inkomstens påverkan på benägenheten att köra för fort

The purpose of the thesis is to investigate whether a higher income make individuals more likely to exceed the speed limit. In addition to income the variables age, sex, perception of the speed of the average driver and offense history for the last three years are taken into account.The method used is based on a survey performed at the mandatory annual motor-vehicle inspection (Bilprovningen). 177 individuals were asked to participate, of these, 124 completed the survey which in turn left us with 117 usable observations.The analysis is based on two forms of regression, a linear regression and an ordered logit regression to confirm the results for the ordinal data.The final model indicates a result where income and age are statistically significant. Sex is considered insignificant for our data material and is excluded from the model. Age has a negative effect on the propensity to exceed the speed limit while income has a positive effect.

Fysisk kapacitet hos fysiskt aktiva och inaktiva ungdomar

Background: During the last decade physical activity among Swedish adolescents has decreased. Changes regarding physical fitness can also be seen, for instance the cardio respiratory capacity has decreased mainly among young men while muscular capacity has decreased in both genders. Physical inactivity and impaired physical fitness are both important health related parameters. 18-year olds have fulfilled their physical development and are physically on top of their development, it makes this group interesting to examine. Objective: The aim of this study was to investigate differences between physically active and inactive young men and women, concerning cardio-respiratory fitness, muscular fitness and balance.

Viktreducering av hydraulmaskin F11-010

Möjligheter att reducera vikten på en hydraulmotor, som tillverkas på Parker Hannifin AB i Trollhättan, har studerats. Målet med arbetet var att ge förslag på hur motorn kan göras lättare för att nå det framtida målet att erbjuda kunder en lättviktsmotor (LWM) lämpad som fläktmotor.För att identifiera komponenterna och deras vikter vägdes alla delar var för sig. Värdena visade att trumhus, lagerhus, axel och lagerpaket stod för ca 75 % av motorns totala vikt. Arbetet koncentrerades därför på att reducera vikten på dessa delar.Flera koncept togs fram med lägre vikt och bibehållen prestanda. Vissa delar kontrollerades mot hållfasthet med handberäkningar och FEM-analyser.

Bach and Improvisation - A research on how useful Bach is for improvising music

I wrote this thesis for myself and someone who would like to learn improvised music not from Jazz but Bach. I analyzed one composition by Bach, then I showed one example of using his idea to a Jazz standard tune. It was challenging for me to understand and analyze his composition as a Jazz improviser. To be honest I don't like to learn the music language from Bebop music but I like to play Jazz standard music. If someone would like to be good at playing jazz music, I think that it is important to know the music language in jazz.

Boksamtal : En språkutvecklande metod för andraspråkstalare

The main purpose of this essay is to study how classroom interaction can take place in a class for Second Language Learners (SLL).1 I have applied a case study methodology on a linguistic method used by a Teacher in Swedish as Second Language working on a primary school situated in the Southern suburbs of Stockholm. The learning method is based on extensive reading of books which comprehend several learning techniques organized into a process that support the development of linguistic skills such as discussing in a group, writing, reading and thinking in a second language. The methodology applied is based on observations, on an interview with a Teacher in Swedish as Second Language and on a questionnaire answered by 11 students that participated on ?Boksamtal?.Based on a theoretical framework about socio cultural theories on learning and scaffolding,2 I attempt to integrate theory and practice to investigate how the Teacher succeed on applying effective methods for second language learning. Through the analyses of the data is also my intention to emphasize the advantages and disadvantages of such a method.

Att styra säkerhet med siffror : En essä om (att se) gränser

Work, especially that in complex, dynamic workplaces, often requires subtle, local judgment with regard to timing of subtasks, relevance, importance, prioritization and so forth. Still, people in Nuclear Industry seem to think safety results from people just following procedures. In the wake of failure it can be tempting to introduce new procedures and an even stricter "rule following culture". None, or at least very little, attention is given to tacit knowledge and individual skills. I am aiming to highlight the inadequacy of putting too much trust in formalization and that reporting and trending of events will contribute to increased learning, an increased nuclear safety and an efficient operational experience.

Energieffektivisering på Skutskärs Bruk : Varvtalsstyrning till utvalda pumpenheter på Blekeri 4

In modern society in terms of economics and environmental impact, it is important to ensure that a company is as energy efficient as possible to reduce the amount of energy used. About 10 TWh of electricity used annually to pump drives in Swedish industry. Therefore, pumping system has great potential for energy savings.The objective of this report was to determine how much energy and money that can be saved with the insertion of variable speed drive to six pumps on Bleach plant 4 in Skutskär Mill. The work was performed with electrical measurements during one week, analysis of pump curves and the compilation of production data over a year.The results show that four of these six pumps were profitable and yielded an annual saving of 1172 MWh of electricity and 560 000 SEK. With an economic lifetime of 10 years and a discount rate of 6.8% the final result for the entire life-cycle savings became 3 355 000 SEK.

En undersökning av röststyrning för Android-enheter

Den tekniska utvecklingen bland mobiltelefoner går ständigt framåt, och med den en förväntan från användarna av högre användarvänlighet hos dem. Standardinmatning har gått från fysiska knappar till pekskärmar, och på senare tid har även röststyrning vunnit mark.Denna rapport behandlar just taligenkänning i mobilapplikationer och undersöker vilka alternativ man har som utvecklare om man vill implementera röststyrning i sina applikationer. Rapporten går igenom vilka fördelar och ?ackdelar det finns med röststyrning, samt vilka begränsningar och problem som uppkommer.Undersökningen genomfördes av två KTH-studenter på uppdrag av Nordens största sökföretag, Eniro. Efter en förundersökning över vilka alternativ som fanns konstaterades det att PocketSphinx, ett taligenkänningssystem som bygger på öppen källkod, lämpade sig bäst för röstnavigering medan Googles tal-till-text-motor var att föredra för röstsökning.En Android-applikation utvecklades där användaren med rösten både navigerar i applikationen, samt genomför sökningar efter företag och telefonnummer..
