In this paper we describe how techniques for refactoring can be used for visual editing of hybrid languages, that is, languages that have both a visual and a textual syntax. Textual languages have name rules that define how name uses are bound to name declarations. These bindings often correspond to connections in the visual language, and need to be taken into account in order to implement the vis

In this paper we analyze two-dimensional (2D) pilot-symbol assisted modulation (PSAM) for wireless orthogonal frequency-division multiplexing (OFDM). 2D-PSAM has been suggested for wireless OFDM by several authors and is included in a preliminary draft of the standard for European digital video broadcast. We generalize the analysis of single-carrier PSAM to the 2D time-frequency lattice of OFDM. W

Lunds Universitets bibliotek testade mellan oktober 2013 och juli 2014 förvärvsmodellen Patron Driven Acquisition (PDA) via e-boksaggregatorn EBL. Arbetet med testet sattes upp i projektform. I följande rapport beskrivs modellen, projektgruppens förberedelsearbete samt resultat av projektet.

Automatic construction of Shape Models from examples has been the focus of intense research during the last couple of years. These methods have proved to be useful for shape segmentation, tracking and shape understanding. In this paper novel theory to automate shape modelling is described. The theory is intrinsically defined for curves although curves are infinite dimensional objects. The theory i

Sustainability has been on the agenda for decades. Yet it is not evident that the development we are witnessing can qualify as sustainable. Departing from an understanding of the adoption of sustainability as an on-going, unfinished process the thesis explores conditions for sustainability in Swedish transport infrastructure policy and planning. The study covers decision processes of three mega-pr

Biogas, a mixture of methane and carbon dioxide, is produced by microorganisms upon degradation of organic matter in an anaerobic environment. It has been realised that by utilising anaerobic processes the organic pollutants in wastewater and organic solid waste from anthropogenic sources can be converted into a renewable source of energy. However, to fulfil the potential of anaerobic digestion in

The studies in this thesis have shown that the partitioning of endoglucanase I (EGI, Cel7B) from T. reesei could be significantly improved by relatively minor genetic engineering. By adding short peptides composed of tryptophan and proline residues to EGI, extreme partitioning could be obtained. The site of the tag fusion was shown to be crucial for the efficiency of the tag. Methods suitable for

The main thrust of CNN technology has been in analog implementations. Early attempts for digital implementations have a limited potential, confining the usage to for instance linear algorithms for B/W pictures. The paper looks into the prospects of successfully integrating the full CNN potential. This requires a carefully tuning of memory and network-on-chip bandwidth to the temporal/spatial aspec

Starting with the assumption that perception is not merely a reaction to outside stimulation but a process of creation, although mostly brief and inaccessible to conscious retrieval, the present paper attempts to determine the prerequisites of a stable and secure accout of reality. The authors’ leading hypothesis is that a dependable end product of adaptive and constructive processes is contingent

A new compact third-order multidimensional residual distribution scheme for the solution of the unsteady Navier-Stokes equations on unstructured grids is proposed. This is a compact cell-based algorithm which uses a finite-element reconstruction over the cell to achieve, its high-order of accuracy. The new compact high-order algorithm has ail excellent parallel scalability, which makes it well sui
