In this paper, we analyze expediting decisions in a continuous-time, continuous-stage serial supply chain facing a Poisson demand process. For each unit in the chain, one must decide at which speed it should be moved downstream, given the state of the system, so as to minimize total supply chain costs. We decompose the problem into a set of one-dimensional subproblems that can be easily solved and

The purpose of this licentiate thesis is to investigate the following hypothesis in a case study: "Occupants of buildings with a quality labeled indoor environment experience a better indoor environment than occupants of buildings with normal planning and construction." The aim of the case study is to compare the outcome of using a quality system for indoor environment with a normal quality system

Among the science challenges of the Extremely Large Telescopes (ELTs),four object types are studied for performance with a 50 m ELT withadaptive optics (AO), Euro50. Emphasis is on planetary systems and verydistant objects. For planetary systems and their evolution, we examinehigh resolution imaging of the nuclei of comets and high-resolutionimaging, photometry and low and intermediate resolution

We investigate how individual workers and local labour markets adjust over a long time period to a discrete and plausibly exogenous technological shock, namely the introduction of containerisation in the UK port industry. This technology, which was introduced rapidly between the mid-1960s and the late-1970s, had dramatic consequences for specific occupations within the port industry. Using longitu

Individualists hold that moral responsibility can be ascribed to single human beings only. An important collectivist objection is that individualism is morally deficient because it leaves a normative residue. Without attributing responsibility to collectives there remains a “deficit in the accounting books” (Pettit). This collectivist strategy often uses judgment aggregation paradoxes to show that

The Ph.D. project concerns itself with curatorial practice, its constituent modalities and potentialities. It consists of both a practical and a theoretical part. These are not separate entities, but immersed in each other. The point of departure is my own practice, but making claims for a general analysis of the politics of exhibition-making. Rather than proving or disproving certain proposition,

With the introduction of new cellular phone standards with increased modulation complexity and signal bandwidth, the design of efficient transmitters will be a major challenge. With this in mind a number of switched mode transmitter architectures are described, both polar and Cartesian ones. The most promising candidates use a combination of supply voltage modulation and other techniques, such as

Popular Abstract in Swedish Radiella gliaceller kan inte bara skapa nervceller utan även inverka gynnsamt på deras mognad. En ny avhandling vid Lunds universitet visar att gliaceller bidrar mer aktivt till nervcellernas utveckling än man tidigare trott. Enbart en transportled för omogna nervceller. Det har länge varit de radiella gliacellernas lott. Men det är inte hela sanningen enligt CharlottaThe current thesis is aimed to increase our understanding of the generation and differentiation of telencephalic neurons, with emphasis on the role of glial cells in these processes. Using in vitro methods we have studied the role of glial cells in neurogenesis, inheritance of genetic regional specification, and influence on differentiation of neurons. We demonstrate that expanded cell cultures ex

Arguing against the presumption that subcultural meaning constitutes a single set of meaning, Hannerz addresses how punks draw upon plural definitions of the mainstream and notions of subcultural authenticity. Drawing from an exceptionally rich fieldwork in Sweden and Indonesia, Hannerz demonstrates that how, where, and against what, punk style and identification are structured and lived comes dow

We study the competition between interference due to multiple single-particle paths and Coulomb interaction in a simple model of an Anderson-type impurity with local-magnetic-field-induced level splitting coupled to ferromagnetic leads. The model along with its potential experimental relevance in the field of spintronics serves as a nontrivial benchmark system where various quantum-transport appro
