The Bidirectional Efficient Algorithm for Searching code Trees (BEAST), which is an algorithm to efficiently determine the free distance and spectral components of convolutional encoders, is implemented for the Cell Broadband Engine Architecture, efficiently utilizing the underlying hardware. Exhaustive and random searches are carried out, presenting new rate R=1/2 convolutional encoding matrices
Evacuation models generally include the use of distributions or probabilistic variables to simulate the variability of possible human behaviours. A single model setup of the same evacuation scenario may therefore produce a distribution of different occupant-evacuation time curves in the case of the use of a random sampling method. This creates an additional component of uncertainty caused by the i
The mechanisms of neuronal cell death are still only poorly understood, which has hindered the advancement of therapies for many currently untreatable neurodegenerative diseases. This calls for the development of new methods which reveal critical molecular mechanisms of the celldeath machinery with both high sensitivity and cellular resolution. Using animal models for hereditary neurodegeneration
In this contribution, a micro-mechanically motivated, energy relaxation-based constitutive model for phase transformation, martensite reorientation and twin formation in shape memory alloys is proposed. The formulation builds on an idealized parametrization of the austenite-twinned martensite microstructure through first- and second-order laminates. To estimate the effective rank-one convex energy
Context. The ESA space astrometry mission Gaia, planned to be launched in 2013, has been designed to make angular measurements on a global scale with micro-arcsecond accuracy. A key component of the data processing for Gaia is the astrometric core solution, which must implement an efficient and accurate numerical algorithm to solve the resulting, extremely large least-squares problem. The Astromet
L-type voltage-gated Ca2+ channels are expressed in the plasma membrane of muscles, neurons and endocrine cells where they serve as conductors of signals regulating cellular responses to changes in environment. Malfunctions of channels, as well as deregulations of their activity underlie numerous disorders and diseases commonly called channelopathies. In β-cells Ca2+ channels are central players f
The article may be seen as a sequel to my paper delivered at a conference on art historical subjectivity and methodology in Stockholm 1999, initiated by Margaretha Rossholm Lagerlöf. – Now I will try to move that analysis a little step further by discussing some problems concerning the more explicit performative effects and experiences of everyday technical objects and their occasionally strange v
Selected reaction monitoring mass spectrometry (SRM-MS) is a targeted proteomics technology used to identify and quantify proteins with high sensitivity, specificity and high reproducibility. Execution of SRM-MS relies on protein-specific SRM assays, a set of experimental parameters that requires considerable effort to develop. Here we present a proteome-wide SRM assay repository for the gram-posi
Pneumothorax occurs more frequently in the neonatal period than at any other time of life and is associated with increased mortality and morbidity. It may be treated with either needle aspiration or insertion of a chest tube. The former consists of aspiration of air with a syringe through a needle or an angiocatheter, usually through the second or third intercostal space in the midclavicular line.
Inspired by centuries of activists who used creative writing as a tool to encourage reflections and inspire change, this thesis looks at the possibility of poetry to be used as an environmental justice tool. In particular the ability of poetry from Nigeria to engage Dutch people with problems around Shell’s exploitation of the Niger Delta and its people, is investigated. Using decolonial and Criti
Denna uppsats syftar till att analysera statsansvar för folkmord, och gör detta mer specifikt genom att undersöka frågan om ansvar för medhjälp till folkmord samt mens rea elementet i folkmordsdefinitionen. År 2007 meddelade ICJ sin dom i the Genocide case, där en av de centrala frågorna för domstolen var ifall en stat kunde hållas ansvarig för folkmord under Folkmordskonventionen. ICJ konstateraThis thesis seeks to analyze the international responsibility of states for genocide, and more particularly does so by looking closer at complicity in genocide and the mens rea element of the definition. In 2007 the ICJ rendered its judgment in the Genocide case, where one of the key issues before the Court was whether a state could be held responsible for genocide under the Genocide Convention.
Data compression methods allow more data to be stored within a certain storage framework while still keeping the characteristics of the data in question. At the Large Hadron Collider on the grounds of CERN in Switzerland, limited data storage capability is and has always been an urgent problem. At the ATLAS experiment, one technique which allows researchers to save more data within the same storag
Planning for capacity in not just the production, but also in the supply chain, is important. Strategic long-term planning for the supply chain will affect how the company will be able to meet the demand. This Master Thesis will focus on the capacities within the supply chain at PolyPeptide and how they could be planned for in the future. PolyPeptide is a company that manufactures active pharmaceu
Matrix functions and their applications play an important role in different fields of science and engineering. The matrix exponential is one of the most important and extensively used function of matrices. The computation of the exponential of a matrix is an interesting topic that has been extensively studied over the years. There are several ways computing the matrix exponential but there is a pu
The Nigerian economy grew at an average rate of 7% between 20002011. However, recent drop in oil prices has led to calls for economic diversification away from oil. Using the services-led growth theoretical framework, this thesis provides an overview of the Nigerian service-sector. Through an analysis of descriptive statistics, the thesis showed that services have been contributing significantly t
