4. 2. Anatomy and taxonomy of cetrarioid lichens

   Author : Arne Thell; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; taxonomi; chemotaxonomy. Physiology of nonvascular plants; phytogeography; morphology; taxonomy; Systematic botany; pycnoconidia; ascus structures; anatomy; Systematisk botanik; cetrarioid lichens; Ascomycotina; Parmeliaceae; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

   Abstract : The anatomy of the cetrarioid lichens (Parmeliaceae) has been studied, and the taxonomy revised. Special attention has been paid to reproductive structures, in particular the asci and pycnoconidia. Two types of asci are recognized. The Cetraria type is narrowly clavate, bears an amyloid ring structure in the tholus, and has a small axial body. READ MORE

5. 3. Housing demand models and housing market models for regional and local planning

   Author : Björn Hårsman; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : I rapporten presenteras en metod som kan användas vid arbete med bostadsbyggnadsprogram på lokal och regional nivå. Ett modellpaket har utarbetats. Det består av en modell för hushållssammansättning, en modell för bostadsefterfrågan och en modell för att ge en bild av konkurrensen på bostadsmarknaden.. READ MORE

6. 4. Morality and the Pursuit of Happiness : A Study in Kantian Ethics

   Author : Johan Brännmark; Praktisk filosofi; []
   Keywords : HUMANIORA; HUMANITIES; Systematic philosophy; Henry Sidgwick; G. E.

   Abstract : This work seeks to develop a Kantian ethical theory in terms of a general ontology of values and norms together with a metaphysics of the person that makes sense of this ontology. It takes as its starting point Kant’s assertion that a good will is the only thing that has an unconditioned value and his accompanying view that the highest good consists in virtue and happiness in proportion to virtue.

7. 5. Coding and Modulation for Wideband CDMA

   Author : Ola Wintzell; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo codes.; Electronics and Electrical technology; channel coding; impulse radio; coordinated transmission; pre-coding; cellular radio capacity; Direct sequence code division multiple access DS-CDMA ; pulse position hopped code division multiple access PPH-CDMA ; Elektronik och elektroteknik; Telecommunication engineering; Telekommunikationsteknik;

   Abstract : Wideband CDMA (Code Division Multiple Access) is one of the key technologies for future mobile communication systems. This thesis studies various coding and transmission methods for wideband CDMA communications. In a cellular environment, the system performance depends on the interference from other cells. READ MORE
