Along with globalization, the use of credit cards has become popular among Chinese urban residents; China has witnessed the tremendous growth in the accumulated number of credit cards issued and the amount of credit loans utilized. The new-classical consumption theory holds individuals responsible for the use of credit loans, however, from Veblen’s institutional perspective, the use of credit card
Problem description: In production and operations management, companies deal with a sometimes huge variety of products. Differences in for example sales volume, demand uncertainty or strategic criticality result in different needs of handling. As a consequence, companies that offer a wide range of products often struggle with the control of their production and inventory systems. An approach that
Using derivative securities can help investors increase their expected returns as well as minimize their exposure to risk. For a risk-averse investor, options can oer both insurance and leverage and for a more risk-loving investor they can be used as speculation. Basket option is a kind of option whose payo depends on an arbitrary portfolio of assets. The basket is made out of a weighted sum of as
Titans struktur Förhållandet mellan materialets struktur och dess egenskaper. När man känner till egenskaperna hos ett material så kan optimala tillverkningsprocesser framställas baserat på denna kunskap. För produkter tillverkade av titan kan detta vara extra viktigt då produkterna ofta används i kritiska tillämpningar i t.ex. rymdraketer eller flygplan. I flygplansmotorer används titanlegeringaAbstract The aim of the project is to determine the mechanical properties and the microstructure with a to b transformation of the titanium alloy Ti-6Al-4V. The experiments made were tensile tests at temperatures 20, 400 and 800C and SEM images before and after inductive methods. Ti-6Al-4V is one of the most used types of alloy mainly because it has good qualities in strength, corrosion resistance
Huvudsyftet med detta examensarbete är att undersöka huruvida webbtexter hos ett inkluderande, politiskt parti fungerar som kommunikativt verktyg ur ett andraspråksperspektiv. Ett ytterligare syfte är att undersöka om det finns specifika aspekter i texterna som andraspråksbrukare upplever som svåra och har svårt att ta till sig, vilket vi antar utifrån tidigare forskning om andraspråk. Vi undersök
Siemens Industrial Turbomachinery has developed dynamic gas turbine models to compute performance parameters such as temperature, pressure, mass flow and power during transients. Results from the current dynamic model correspond to measured data except for gas channel temperatures that change too fast during transients. The measurement of gas channel temperature is also a source of error due to th
In battery operated devices, such as mobile phones, power consumption is an important constraint, as it has a direct impact on the battery lifetime. Trying to extend the battery lifetime as much as possible has been one of the major targets in device development for the past years. Together with advances in the battery technology, several techniques, usually referred as low-power design techniques
Uppsatsens syfte är att fördjupa insikten i hur verksamheter som traditionellt inte ses som kunskapsintensiv hanterar tvetydighet. För att nå syftet med uppsatsen har en kvalitativ studie genomförts. Uppsatsen har en utgångpunkt från en tolkande kunskapssyn på studieobjekten och har en induktiv ansats. Den teoretiska referensramen består inledningsvis av kunskapsintensiva verksamheters karaktäristThe purpose of the paper is to deepen the understanding of a nontraditional knowledge-intense organization and how they manage clarity. In order to reach the purpose of this paper a qualitative study has been conducted. The paper has adopted an interpretative approach of knowledge and has an inductive approach. The theoretical framework is based on theories about characteristics of knowledge-inten
Today, bioethanol is predominately produced with conventional feedstock that may not be desired for ethanol production due to their primary food and animal feed value. Therefore, lignocellulosic biomass, a relatively cheap and non-food competitive biomass has received attention. However, the complexity of lignocellulosic biomass poses challenges to developing a large-scale production process compe
Denna masteruppsats är ett sammarbete mellan Siemens Industrial Turbomachi- nery (SIT) och Lunds Tekniska Högskola (LTH). Uppsatsen berör validering av ett nytt in-house verktyg på SIT som heter ”Mean Line Tool” (MLT), framför allt sekundärförlustmodellerna som verktyget använder. Valideringen gjordes genom att undersöka och jämföra predikteringar från MLT med experiment utförda på en testturbin vThis thesis for the degree of Master of Science is a collaboration between Siemens Industrial Turbomachinery (SIT) and Lund Institute of Technology (LTH). This thesis concerns validation of a new SIT in-house code Mean Line Tool (MLT) and especially the secondary loss models used by this tool. The validation was made by investigating and comparing predictions from MLT with experiments carried out
Syfte: Studien syftar till att genom empiriskt underlag från franchiserelationer bidra med ytterligare information angående hur en agents förtroende för en principal påverkar en agents opportunistiska beteende, och i förlängningen huruvida en agents förtroende för en principal är en faktor som bör beaktas i transaktionskostnadsteorin. Metod: Studien genomfördes med kvalitativ metod där en induktiPurpose: The study aims at, on an empirical basis of franchise relationships, to provide further details on how the agent's trust in the principal affects the agent's opportunistic behavior, and ultimately whether the agent's trust in the principal is a factor to be considered in the transaction cost theory. Methodology: The study is a qualitative research where an inductive approach

The following three areas were investigated: • Process water purification, coagulation and flocculation • Flue gas condensate, mercury reduction • Stormwater ponds, degree of purification The coagulation and flocculation of the process waterwas in need of optimizatio
Current drawback in mass spectrometry-based lipidomics is the absence of a global and comprehensive lipid mass spectra library. Thus, the construction of such library was necessary, serving as a tool in different research projects. A liquid-liquid extraction (LLE) method for extraction of lipids from bovine serum and human blood plasma has been developed. Moreover, two different approaches were us
Hög energieffektivitet och god fordonsdynamik är två av de viktigaste fokusområdena för drivsystem i personbilar. En central komponent i BorgWarner:s produkter för momentöverföring är en lamellkoppling som regleras med hjälp av trycksatt olja från en hydraulisk axialkolvpump. Ett alternativ för att reducera energiförbrukningen och samtidigt förbättra pumpens prestanda är att variera pumpens deplacEnergy efficiency and good vehicle dynamics are two of the main focus areas for passenger car drive systems. A central component in BorgWarner’s torque transfer products is a multi-plate clutch which is actuated by pressurized oil from a hydraulic axial-piston pump. One way to reduce the energy consumption and improve the performance of the pump is to let the displacement of the pump vary dependin
