Ständiga förbättringar är viktiga för att upprätthålla ett företags konkurrenskraft inom sin bransch. Kunderna vill ha en hög leveranssäkerhet och flexibilitet för sina ordrar, men utförande från tillverkningsföretagens sida riskerar att vara bristande. Därför kan utförandet av kartläggningar och mätningar av orderprocessen, i kombination med förbättringar, stärka ett företags vidare konkurrenskraContinuous improvement is important for maintaining a company’s competitive position in its own industry. Customers want a high delivery reliability and flexibility for their orders, but the performance of the manufacturers is likely to be deficient. Therefore, the execution of mapping and measurements of the order process, combined with improvements, enhance corporate competitiveness further. An

The natural elements are used as a driving force for positive urban life in Akureyri, Iceland with the snow accumulation as a leader to unite the town in a physical and social way. The elements of snow buildup in the urban environment are used to find ways to give the town added value in the form of recreational opportunities and commuting routes. Additionally using a system of snow storage to min

This study aims to examine how the sensitivity for macroeconomic announcements surprises changes for the exchange rate in terms of a crisis. Previous research has been biased for U.S announcements and their relation towards emerging market, which has shown that U.S announcements affect more than the domestic. It also suggests that business cycle and uncertainty affect and increase the reaction for

The purpose of this study has been to investigate the experience of being a child challenging the food culture one was born into by going vegetarian. Five grown up informants who made a conscious and deliberate choice to abstain from meat during childhood have had the opportunity to tell their stories through a semi-structured interview. The interviews were analyzed thematically by means of Interp

Business Rules är regler som definierar en del av en affärsverksamhet. I stora IT-system är det viktigt att snabbt kunna hitta den regel som skall appliceras, en uppgift som blir allt mer tidskrävande när antalet regler ökar.Business Rules Engines are systems created to deliver relevant business information to applications and business processes. Given that rule engines are meant to be heavily queried, efficient rule search is essential. However, since the advent of Big Data, it has become increasingly difficult to maintain the rule engine performance - more data often leads to more rules. In this thesis we prototype

Förbättringar i reproducerbarhet och kapacitet av akustiska mikrofluidiska infångningssystem Vad är akustisk infångning? Arbetet i den här uppsatsen är fokuserat på mikrofluidiska system som med hjälp av ultraljud kan fånga in celler och små partiklar. Mikrofluidik är ett fält som innefattar tekniker där man hanterar små flöden i mycket små kanaler. Principen för akustisk infångning bygger på attAcoustic trapping is a novel technology that allows for microfluidic sample preparation and pretreatment. The aim of this text is to give the reader a general insight in microfluidics with a focus on acoustic trapping. One of the next steps in the development of acoustic trapping is to promote commercialization of the technology which requires that similar devices can be manufactured reproducibly.

De första mikrosekunderna efter Big Bang (den stora smällen) tros det ha bildats något som kallas kvark-gluonplasma. Kvark-gluonplasma består av kvarkar och gluoner, som är så kallade elementärpartiklar. Elementärpartiklar är de minsta kända beståndsdelarna. Kvarkarna bygger upp större partiklar som kallas hadroner, exempel på hadroner är protonen och neutronen som atomkärnan består av. Det som håIn high-energy heavy-ion collisions, a state of matter called quark-gluon plasma (QGP) can be created. The production of particles from the QGP can be described by different models, one of these is the blast-wave model. The blast-wave model describes the production of particles from the QGP, not from jets. The model was fitted to the existing transverse momentum spectra (pT) for pions, kaons and p

The turbo code used in the 3GPP Long Term Evolution(LTE) standard have been chosen specifically to simplify parallel turbo decoding and thus achieving higher throughputs. The higher data rates however leads to an increased computational complexity and thus a higher power and energy consumption of the decoder. This report presents a turbo decoder for the LTE standard with a stopping crite- ria aime

One of the most pressing present day health concern is the constantly growing increase of diabetes and the metabolic syndrome. In fact the WHO estimates that as much as 300 million individuals could suffer from diabetes by 2025. While genetic factors do contribute to these issues the more common cause is modern day environmental factors like diets rich in fat or highly processed food, low levels oCan meal order influence blood glucose and insulin levels? When carbohydrates like white bread, rice etc. are consumed, glucose levels in the blood start to rise.Depending on how fast this rise in blood glucose levels occurs carbohydrates can be divided into high GI and low GI foods. High GI foods like bread, potatoes etc. cause a rapid spike in blood glucose levels while low GI foods like pasta c

The worlds’ human population is continuously growing, and meeting the increased demand for food requires an increase of agricultural production. Agricultural ecosystems are of great importance for humans in terms of delivering provisioning ecosystem services, such as the production of food. The term ecosystem service is a function provided by natural environments, that are beneficial for humans. A

You might have heard the expression that the eyes are the window to the soul, but what if the eyes are also the window to the brain? What if you could see what happens in a person’s brain only by looking into their eyes? There is indeed a physical link between the eyes and the brain. The retina, the part of the eyes that is responsible for collecting incoming light, develops from a part of the b

The RF power amplifier is one of the most critical blocks of transceivers, as it is expected to provide a suitable output power with high gain, efficiency and linearity. In this paper, a 60-GHz power amplifier based on an injection locked structure is demonstrated in a standard 65 CMOS technology. The PA core consists of a cross-coupled pair of NMOS transistors with an NMOS current source. This st
