Three-dimensional boundary finding based on Fourier surface optimization is presented as a method for segmentation of SPECT images. Being robust against noise and adjustable with respect to its detail resolution, it forms an interesting alternative in this application area. A three-dimensional approach can also be assumed to increase the possibility of delineating low contrast regions, as compared

Beyond indexicality in the semiotics of photography.
In this paper we discuss parallelization and distribution of problems modeled in a constraint programming (CP) framework. We focus on parallelization of depth-first search methods, since search is the most time-consuming task in CP. The current hardware development is moving towards multi-core processors and the cost of building distributed systems is shrinking. Hence, parallelization and distribu

To fully utilize the available spectrum for a wireless communication system it is feasible to adapt to different situations on the channel. In this paper a flexible OFDM transmitter is presented together with basic theory behind OFDM transmission. It is shown that high flexibility can be obtained with a reasonable amount of additional hardware. Part of the design, the FFT-processor, has already be
Popular Abstract in Swedish Drömmen om evigt liv och evig ungdom är inte ny. Föreställningarna om vägen dit är ungefär desamma idag som för 300 år sedan. Men de tekniska möjligheterna har vidgat gränserna. Att förbli ung, eller åtminstone se ung ut, är ett ideal som växer sig allt starkare. Åldrande och död ska bekämpas, att hålla sig ung och att leva länge är viktigt. Det gäller att träna och skThe aim of this thesis is to explore discursive changes in conceptions of life course and ageing. In a sense the Life- Span embodies the boundaries of human existence, but furthermore, it symbolizes a discursive system with distinctive symbols and meaning, that regulates and re-construct a cultural context. Hence, a cultures notion of the Life-Span also reveals its images and apprehensions of agei
Sharp density features in protoplanetary discs, for instance at the edge of a magnetically dead zone, have recently been proposed as effective barriers to slow down or even stop the problematically fast migration of planetary cores into their central star. Density features on a radial scale approaching the disc vertical scaleheight might not exist, however, since they could be Rayleigh (or more ge
An improved conventional-to-micro/minichannel threshold was proposed as Bo = 4 and BoRe(1)(0.5) = 200, where Bo is the Bond number and Re-1 is the liquid Reynolds number. The region Bo < 4 and BoRe(1)(0.5) < 200 is termed as micro/minichannel because bubbles tend to be confined and elongated in the channel and the conventional two-phase flow theory loses its applicability. Flow-pattern based heat
On 2 November 1994, the Human Rights Committee adopted General Comment No. 24 (52), which was clearly provoked by the great number of reservations deposited by States to the International Covenant on Civil and Political Rights (ICCPR) and its two Optional Protocols. In this decision, the Committee states its opinion on a variety of matters. All relate to the permissibility and effect of reservatio
This chapter examines the relationship between individual and organizational identity in PSFs and the significant but tenuous nature of elite identity in this context. The authors identify four main identity-related issues for management control in PSFs: autonomy/conformity tensions, the client conundrum, ambiguity saturation, and intangibility. They explore three main modes of identity-focused co
The database of photographic meteor orbits of the IAU Meteor Data Centerin Lund has gradually been updated. The version 2001, which has beenprepared for distribution and which will be released soon, containscomplete orbital and geophysical data on 4581 meteors (equinox J2000.0).A new meteor identification code consisting of the publication serialnumber, the author or station code and number of the
Övergångsrättvisa (transitional justice) är en term som beskriver hur länder med hjälp av juridiska och icke-juridiska åtgärder hanterar storskaliga övergrepp mot mänskliga rättigheter. Övergångsrättvisa används bland annat för att hålla förövare ansvariga och bringa försoning. Konceptet övergångsrättvisa växte fram som ett gensvar på hur länder under 1980–1990-talet hanterade de storskaliga övergTransitional justice is a term and concept which describes how countries deal with large-scale human rights abuses through different judicial and non-judicial measures in order to achieve reconciliation and hold perpetrators accountable. Transitional justice as a concept was born out of practice as a response to how countries in the 1980–1990s dealt with large-scale abuses committed by the earlier
Det framgår av 7 § LAS att en uppsägning måste vara sakligt grundad. Vad som utgör saklig grund för uppsägning finns inte närmare angett i lag mer än att en uppsägning inte är sakligt grundad om det är skäligt att arbetsgivaren erbjuder arbetstagaren annat arbete hos sig, 7 § 2 st. LAS. Arbetsgivarens omplaceringsskyldighet gäller både vid uppsägningar på grund av personliga skäl och uppsägningar For a dismissal to be lawful it must fulfil the just cause requirement stipulated in Section 7 of LAS. The just cause requirement is not defined in neither LAS nor any other statute. Section 7 of LAS only explains that just cause will not be found if it is reasonable to demand that the employer provides the employee with different work tasks or transfers the employee to some other available positi
Umgängesrätten ska bedömas i enlighet med barnets bästa, Föräldrabalken 6 kapitlet 2a §. Man ska då fästa särskilt avseende vid barnets behov av en nära och god kontakt med båda föräldrarna och vid risken att ett barn far illa. Barnets bästa är inte definierat i lagtext för att kunna appliceras i varje unik situation och därför är termen även anpassad till samhällets utveckling. Att barn bevittnar
Purpose: The importance of body positivity is visible in its remarkable media presence. The movement entails challenges such as opportunities for brands. The purpose of this paper is to examine why companies adapt to the body positivity movement, what they are exactly doing regarding body positivity and how this is related to the brand’s reputation. Methodology: Literature and media review, Case
Syftet med denna uppsats är att undersöka de narcissistiska dragen hos tre romankaraktärer: Dorian Gray i Oscar Wildes Dorian Grays porträtt (1890), dvärgen i Pär Lagerkvists Dvärgen (1944) och Marcel i Björn Larssons Drömmar vid havet (1997). Narcissism definieras som ett personlighetsdrag som utmärks av grandiositet, behov av beundran och bristande empati, och som bottnar i en inre känsla av skaThe purpose of this paper is to explore the narcissistic traits in three fictional characters: Dorian Gray in Oscar Wilde’s The Picture of Dorian Gray (1890), the dwarf in Pär Lagerkvist’s The Dwarf (1944), and Marcel in Björn Larsson’s Dreams by the Sea (1997). Narcissism is defined as a personality trait characterized by grandiosity, need for admiration, and lack of empathy, stemming from an inn
