Att separera två eller flera inspelade ljudsignaler är generellt ett svårlöst problem, men det blir enklare att lösa desto mer signalerna skiljer sig från varandra. Genom att använda en parabolformad reflektor går det att skapa skillnader mellan signalerna på ett sådant sätt att signalseparationen kan förbättras.This master’s thesis studies the use of physical structures for signal source separation. A parabolic reflector was used to alter the directional properties of one microphone in a two-microphone array. A method to estimate the mixing channels from measured data is presented, as well as a method to find the optimal separating channels. Measurements of the directional properties and mixing channels

In LSS staff´s work with autism they relate daily to the international diagnostic manual (DSM) where the American Psychiatrich Association has categorized and globalized the diagnostic criteria. The work has been debated and criticized by social anthropologists as an expression of society's need to categorize, to medicalise suffering and to globalize western expression of suffering. Every day

In recent times, as the construction industry moves towards high-rise structures, under seas tunnels and mega infrastructure projects, companies face hard time managing the construction that continuously evolves for achieving new methods of engineering and supervision. Depending on the size and sensitivity of the project, the owners choose the construction company; i.e. mega projects require mega

Förtillverkade betongkonstruktioner har inte någon naturlig sammanhållning av stommen, som i en platsgjuten konstruktion, vilket medför stora krav på de mekaniska kopplingarna mellan de prefabricerade betongelementen avseende bärförmåga och deformationskapacitet. Dagens mekaniska kopplingar utgörs ofta av ingjutna raka kamstänger och har därför en begränsad deformationskapacitet vilket medför att Precast concrete structures has no natural coherence of the frame as when the structure is cast in situ, which puts great demands on the ties between the prefabricated concrete elements regarding the resistance and deformation capacity. The ties that are used today often consist of straight ribbed bars embedded in concrete and therefore have limited deformation capacity. This means that the opport

Syfte: Syftet med vår studie är att belysa ifall genus har någon påverkan på revisorers bedömningar av väsentlighet för att i så fall skapa en medvetenhet om hur eventuella skillnader kan påverka bedömningen. Teoretiska perspektiv: Socialiseringsteori med genusfokus. De flesta mönster i kvinnligt och manligt beteende beror på socialisering snarare än de biologiska skillnaderna. Detta ligger delvisPurpose: The aim of our study is to elucidate whether gender has any effect on the auditor’s assessment of materiality in order to create an awareness on how any differences might affect the assessment. Theoretical perspectives: socialization theory with gender focus (gender differences depend more on social factors than biological) which partly explains the theory of women being more risk-averse

Cooked ham is a particularly popular cured meat product. Nonetheless, meat consumption constitutes a controversial issue, as researchers correlate red and cured meat with the development of colorectal cancer. One of the main compounds of the cured cooked ham is nitrite. Although, its residual amount in products is considered as responsible for the formation of N-nitrosamines and the provocation of

I en tid där befolkningen ökar och medellivslängden blir äldre förändras villkoren för vården. Den största kostnaden inom svensk vård idag är relaterade till äldre människor och fallskador. I den här uppsatsen presenteras en framtagen lösning som detekterar fall och sparar information om vad som händer under ett fall. Ett fall i sig självt är väldigt svårt att stoppa, men det finns faktorer runt mIn a time when the population and life expectancy increase, the demands on health care change. The biggest cost in Swedish health care today is related to accidents regarding falls of old people. This Master's thesis presents a solution to fall detection and logging of data from falls. Falls themselves are hard to stop, but there are several factors behind falls that can be changed in order to

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.

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
