Instruction Selection and Scheduling for DSP Kernels on Custom Architectures

As custom architectures become more and more common for DSP applications, instruction selection and scheduling for such applications and architectures become important topics. In this paper, we explore the effects of defining the problem of finding an optimal instruction selection and scheduling as a constraint satisfaction problem (CSP). We incorporate methods based on sub-graph isomorphism and g

Evolution and consequences of polygyny in leptothoracine ants

In this thesis the evolution and consequences of multiple queen societies (polygyny) in leptothoracine ants are discussed. The majority of the studies have been conducted on the boreal species Leptothorax acervorum, but polygynous behaviour is also discussed in a broader sense concerning ant species in general. In L. acervorum the intra-colony relatedness is high. Relatedness in monogynous colonie

Calculated Potential Energy Surfaces and Vibrational Analysis

The focus of this thesis is on the calculation of potential energy surfaces and on the study of vibrational properties. For example: - We have developed a new method for calculation of Franck-Condon factors. - We have calculated full energy surfaces of the ground (X2A’) the excited (B2A’) states of the formyl radical. These surfaces have been used to study the hydrocarbon flame bands of the B2A’

Johan Jakob Borelius – den siste svenske hegelianen

Johan Jakob Borelius var professor i teoretisk filosofi vid Lunds universitet från 1866-1898. Boken belyser den syn på filosofin som Borelius gav uttryck för när han tillträdde sin professur. Vidare ges en inblick i hans trettioåriga verksamhet som professor. Särskilt utrymme ägnas åt Borelius syn på motsägelsesatsens innebörd och giltighet, liksom det stora verket "Metafysik" som han arbetade på

The Columnar Lined Esophagus. Pathophysiological and Clinical Aspects

Popular Abstract in Swedish Gastroesofageal refluxsjukdom är ett tillstånd som kännetecknas av att magsyra åker upp i matstrupen (reflux). Reflux är ett normalt fenomen som förekommer hos alla individer utan att orsaka symtom eller vävnadsskador. Hur detta normaltillstånd utvecklas till ett sjukdomstillstånd är ej helt klarlagt. Reflux förhindras normalt av en barriär vid övergången mellan matstruThere is a persisting controversy concerning the definition, etiology and pathogenesis of Barrett's esophagus. The dramatic and parallel increase in the incidence of esophageal and junctional adenocarcinoma over the past decades justifies an evaluation of the pathophysiology of premalignant metaplastic changes of the esophagus and the gastroesophageal junction. Patients were evaluated with upper G

What's in a schema? Bodily mimesis and the grounding of language

The chapter defines mimetic schemas as dynamic, concrete and preverbal representations, involving the body image, which are accessible to consciousness, and pre-reflectively shared in a community. Mimetic schemas derive from a uniquely human capacity for bodily mimesis (Donald 1991; Zlatev, Persson and Gardenfors 2005) and are argued to play a key role in language acquisition, language evolution a

Neural Network Ensembles and Combinatorial Optimization with Applications in Medicine

Popular Abstract in Swedish Inom medicin, och inom många andra tillämpningar, är uppgiften ofta att utifrån en serie observationer ge ett jakande eller nekande svar på en viss fråga. Exempelvis måste en läkare avgöra om en patient med bröstsmärtor lider av akut hjärtinfarkt eller inte. Artificiella neurala nätverk är en sorts datorprogram som själv förmår "lära" sig att svara på sådana frågor. NäArtificial neural network (ANN) and combinatorial optimization algorithms are developed, and applied to the medical domain. A novel method for training an ensemble of ANN is presented, based on random weight updates alternated with replication of networks with low error. The evolution of the ensemble is explored, with particular emphasis on its diversity and internal correlation. The performance
