A New Method for Mapping Optimization Problems onto Neural Networks
A novel modified method for obtaining approximate solutions to difficult optimization problems within the neural network paradigm is presented. We consider the graph partition and the travelling salesman problems. The key new ingredient is a reduction of solution space by one dimension by using graded neurons, thereby avoiding the destructive redundancy that has plagued these problems when using s
Haemodynamics and Flow Modification Stents for Peripheral Arterial Disease : A Review
Endovascular stents are widely used for the treatment of peripheral arterial disease (PAD). However, the development of in-stent restenosis and downstream PAD progression remain a challenge. Stent revascularisation of PAD causes arterial trauma and introduces abnormal haemodynamics, which initiate complicated biological processes detrimental to the arterial wall. The interaction between stent stru
Variability of computational fluid dynamics solutions for pressure and flow in a giant aneurysm : the ASME 2012 Summer Bioengineering Conference CFD Challenge
Stimulated by a recent controversy regarding pressure drops predicted in a giant aneurysm with a proximal stenosis, the present study sought to assess variability in the prediction of pressures and flow by a wide variety of research groups. In phase I, lumen geometry, flow rates, and fluid properties were specified, leaving each research group to choose their solver, discretization, and solution s

Long-wavelength intersubband quantum disc-in-nanowire photodetectors with normal incidence photoresponse
Semiconductor nanowire (NW) technology has emerged as a key facilitator of novel optoelectronics e.g. solar cells, photodetectors and LEDs. The functional wavelength range of current NW-based photodetectors is typically limited to the visible/near-infrared region. In this work, we present the first ever reported electrical and optical characteristics of longwavelength IR photodetectors based on la
Folkbildning för delaktighet : En studie om bibliotekets demokratiska uppdrag i en digital samtid
This dissertation explores the public library’s democratic and popular educational role in a time when knowledge- and cultural institutions are affected by changes related to digitalisation. The purpose of the study is to examine how library activities, which in various ways are intended to increase individuals’ digital skills, information literacy and participation in society can be understood an
Beam performance of the photocathode gun for the MAX IV LINAC
The MAX IV facility in Lund (Sweden) is under construction and conditioning of the electron guns for the injector is ongoing. There are two guns in the injector, one thermionic gun for storage ring injection and one photocathode gun for the Short Pulse Facility. In this paper we report on the beam performance tests of the photocathode gun. The measurements were performed at the MAX IV electron gun

Continental mapping of forest ecosystem functions reveals a high but unrealised potential for forest multifunctionality
Humans require multiple services from ecosystems, but it is largely unknown whether trade-offs between ecosystem functions prevent the realisation of high ecosystem multifunctionality across spatial scales. Here, we combined a comprehensive dataset (28 ecosystem functions measured on 209 forest plots) with a forest inventory dataset (105,316 plots) to extrapolate and map relationships between vari
Thin-Film Growth and Oxidation of Surfaces Under Relevant Pressure Conditions
The growth of oxides and thin films is important in a wide range of applications, including coating technology, production of solar cell materials, and formation of dielectric layers in the semiconductor industry. These growth processes necessitate the interaction of a solid surface with a gas/vapor or liquid phase. The chemical processes that take place during the interaction of the solid with th

Extended behavior trees for quick definition of flexible robotic tasks
The requirement of flexibility in the modern industries demands robots that can be efficiently and quickly adapted to different tasks. A way to achieve such a flexible programming paradigm is to instruct robots with task goals and leave planning algorithms to deduct the correct sequence of actions to use in the specific context. A common approach is to connect the skills that realize a semanticallhe requirement of flexibility in the modern industries demands robots that can be efficiently and quickly adapted to different tasks.

Motion Generators Combined with Behavior Trees: A Novel Approach to Skill Modelling
Task level programming based on skills has often been proposed as a mean to decrease programming complexity of industrial robots. Several models are based on encapsulating complex motions into self-contained primitive blocks. A semantic skill is then defined as a deterministic sequence of these primitives. A major limitation is that existing frameworks do not support the coordination of concurrentTask level programming based on skills has often been proposed as a mean to decrease programming complexity of industrial robots.
