The aim of this thesis is to identify a speaker in a video stream by only using the camera of a smartphone. This creates the opportunity for a mobile application to track the speaking participant during a conference call. Conference systems that include this feature use a microphone array to localize sound and who the speaker is. Mobile phones however, are generally not equipped with a microphone
This thesis is based on fifteen semi-structured interviews with key actors of the Syrian political opposition. It explores the major limitations that faced the Syrian National Council (SNC) and the National Coalition for Syrian Revolutionary and Opposition Forces (NOC). Within the theoretical frameworks of political opportunity and fragmentation, this research identifies four major limitations whi
The paper presents the theories of Peter Singer and Tom Regan concerning the moral status of animals and why both deem animals to have a moral standing similar to humans. The two theories differ in their approaches to justifying the moral standing of animals and humans but have very similar conclusions. The paper then goes on to show how both theories have potential problems in justifying that the
Water mist systems have seen an increase in use as an alternative clean agent fire suppressant since the late 1980s after the use of Halon gases were discontinued. One of the potential uses of these systems is to provide a protective curtain between a fire and desired target. The following experimental work investigates the radiation attenuation abilities of a single water mist spray. These experi
This thesis looks at the effects a coffee cooperative in the municipality of Salgar has on its member farmers, and its implication for rural development in the region. Coffee cooperatives have become important strategic institutions within the coffee sector in the country, instigated by the National Coffee Growers Federation. It is the only agricultural sector in the country where farmers can be g
Leverantörsutveckling började under och efter andra världskriget att utvecklas i Japan. Traditionellt sett fokuserade industrin på leverantörer med lågt inköpspris och att byta ut leverantörer som inte presterade tillräckligt bra. Idag är det emellertid känt att byte av leverantörer inte är kostnadseffektivt och därmed har vikten av leverantörsutveckling ökat. Detta är även tydligt då både industr
If, as recent scholarly insights suggest, adherence to Jesus was a largely intra-Jewish affair during the first few centuries ce, it increases the likelihood of interaction and exchange of ideas between such Jesus-oriented Jews and Jews of other inclinations. This article argues that the motif of the atoning power of the death of the beloved son - developed within first-century Judaism, as evidenc
Using first-principles methods, we study theoretically the properties of an individual {Fe-4} single-molecule magnet (SMM) attached to metallic leads in a single-electron transistor geometry. We show that the conductive leads do not affect the spin ordering and magnetic anisotropy of the neutral SMM. On the other hand, the leads have a strong effect on the anisotropy of the charged states of the m
An informal home caregiver is a person (family member or friends) who takes care of or participates to some degree in the care of a person in the home. This study provides a selected review of literature published 1982-2003 of the informal home caregiving from a gender perspective. A computer-aided search using MEDLINE and CINAHL was carried out. The final number of articles was 45. The main findi
We consider the minimum line covering problem: given a set S of n points in the plane, we want to find the smallest number l of straight lines needed to cover all n points in S. We show that this problem can be solved in O(n log l) time if l is an element of O(log(1-is an element of) n), and that this is optimal in the algebraic computation tree model (we show that the Omega(n log l) lower bound h
The nociceptive spinal reflex system performs highly precise sensorimotor transformations that require functionally specified synaptic strengths. The specification is gradually attained during early development and appears to be learning dependent. Here we determine the time course of this specification for heat-nociceptive tail withdrawal reflexes and analyze which types of primary afferents are
The DyDOC model simulates the C dynamics of forest soils, including the production and transport of dissolved organic matter (DOM), on the basis of soil hydrology, metabolic processes, and sorption reactions. The model recognizes three main pools of soil C: litter, substrate (an intermediate transformation product), and humic substances. The model was used to simulate the behavior of C in the 0 ho
Augmented Reality (AR) är på uppgång och många företag lägger miljontals dollar i branschen. Både Google och Apple har nyligen släppt sina egna AR SDK’er som kommer att köras på miljontals enheter inom en snar framtid. AR är verkligen fascinerande och har sagts vara nästa miljard-industri. Målet med denna avhandling är att undersöka vad som är möjligt med dagens AR för mobila enheter och undersökaAugmented Reality (AR) is on the rise and a lot of companies put millions of dollars into the industry. Both Google and Apple have recently released their own AR SDKs that will run on millions of devices in the near future. AR is really fascinating and have been said to be the next multi-billion-dollar industry. The goal of this thesis is to explore what is possible with today’s AR and what are th
This Master’s Thesis contributes with a rich description of normative control as a social process, through the illustration and interpretation of the practical efforts and sense-making that surround it. These contributions are made possible through an ethnographic case study at a medium-sized, fast-growing dotcom company with a distinct and salient corporate culture and normative control efforts.
The ever-increasing interest in electrical vehicles around the world creates a strong developing curve for demand for batteries in electrical vehicles. Meaning, the batteries needs to be able to function better and for a longer time without being destroyed in the process. At the same time the batteries also needs to be rechargeable to not unnecessarily pollute the environment. A battery management
