One of the aims of outdoor lighting in public spaces, such as pathways and subsidiary roads, is to help pedestrians to evaluate the intentions of other people. This paper discusses how a pedestrians' appraisal of another persons' intentions in artificially lit outdoor environments can be studied. We review the visual cues that might be used, and the experimental design with which effects of change
Many popular direction-of-arrival (DOA) estimators rely on the fact that the array response vector of the array is Vandermonde, for example, that of a uniform linear array (ULA). Array interpolation is a preprocessing technique to transform the array response vector of a planar array of arbitrary geometry to that of a ULA over an angular sector. While good approximation within the target sector is
Due to the nature of the engine cycle, heat transfer has a significant role in the estimation of engine efficiency. The effects are quite well known in the classic combustion concepts, compression ignition (CI) and spark ignition (SI) combustion. But for the newer, low temperature combustion (LTC) concepts, these effects are not that well known. In this paper, a commercial computational fluid dyna
We describe JastAdd, a Java-based system for specifying and implementing the parts of compiler front ends that follow parsing. The system is built on top of a traditional Java parser generator which is used for parsing and tree building. JastAdd adds facilities for specifying and generating object-oriented abstract syntax trees with both declarative behavior (using Reference Attributed Grammars (R
In this article, we describe a system that classifies relations between entities extracted from an image. We started from the idea that we could utilize lexical and semantic information from text associated with the image, such as captions or surrounding text, rather than just the geometric and visual characteristics of the entities found in the image. We collected a corpus of images from Wikipedi
An in-house written software package was used to generate templates of QRS complexes and T waves using self-similarity techniques, and leave a residual signal representing only atrial activity. The templating performance differences between individual ECG leads were tested. The mean number of templates in each of the 3 ECG leads was 8±4, 2±1, 7±5 for the QRS complexes, and 11±5, 11±8, 10±5 for the
In many organizations, the Chief Information Officer is considered to preside over a separate function, providing a service to the business. Discussions about governance are confined to properties of this service, e.g. through a service level agreement. Members of the CIO’s staff are often seen as technical experts possessing esoteric skills desired but not understood by other staff. Many research
The article deals with stabilisation and regeneration of CeO2 and CeO2/ZrO2 based Pt water gas shift catalysts, subject to high initial deactivation. The reaction gas species effect on the catalyst deactivation was investigated by H2-TPR. Activity measurements enabled the effect of different promoters, some added to the CeO2 based catalysts and some to the CeO2/ZrO2 based Pt catalysts, to be inves
This purpose of the study was to increase the visibility on radar for unprotected pedestrians with the aid of conducting fabric. The experiment comprised measurements of four types of fabric to determine the radio frequency properties, such as radar cross section (RCS) for the vehicle radar frequency 77 GHz and transmission (shielding) in the frequency range 3-18 GHz. Two different thicknesses of
This paper investigates the L2 acquisition of clausal syntax in post-puberty learners of German and Swedish regarding V2, VP headedness and verb particle constructions. The learner data are tested against L2 theories according to which lower structural projections (VP) are acquired before higher functional projections (IP, CP), VP syntax is unproblematic (invulnerable), but where grammatical opera
Runoff estimation is of high importance for many practical engineering applications so that, e.g. power production, dam safety and water supply can be ensured. The methods and time step relevant for runoff simulations vary depending on the location and the application. Long-term runoff simulation for Scandinavia is of high importance as its hydropower production is affected by climate variability,
Using the Fourier Transform Spectrometer at Lund Observatory, intensity calibrated spectra of singly ionized zirconium have been recorded and analyzed. Oscillator strengths for 263 Zr II spectral lines in the region 2500-5400 angstrom have been derived by combining new experimental branching fractions with previously measured radiative lifetimes. The transitions combine 34 odd parity levels with 2
Combustion processes serve as important sources of energy for both power generation and for transport, ranging from large scale power stations to micro turbines and aeroplane engines. Lean premixed combustion offers a potential to reduce the emission levels, but suffers from instability problems which can be overcome by the use of active control. This thesis addresses the problem of actively contr
The protonation status of key residues and bound ligands are often important for the function of a protein. Unfortunately, protons are not discerned in normal protein crystal structures, so their positions have to be determined by more indirect methods. We show that the recently developed quantum refinement method can be used to determine the position of protons in crystal structures. By replacing
An algorithm for the burst detection and location in water distribution networks based on the continuous monitoring of the flow rate at the entry point of the network and the pressure at a number of points within the network is presented. The approach is designed for medium to large bursts with opening times in the order of a few minutes and is suitable for networks of relatively small size, such
Histologic grade, including tubular formations, nuclear grade, and mitotic activity, is a well-documented prognostic factor in breast cancer. In comparison with other prognostic parameters, the evaluation of histologic grade is cheap and can be performed, in principle, in all cases of breast cancer. One possible disadvantage is that the evaluation may vary between different pathological department
This paper provides a production and consumption-based empirical macroeconomic-climate assessment of Sweden’s CO2 emissions. The core methodology is based on three complementary quantitative methods, namely energy-economy-environment indicators, econometric analyses, and a multi-regional input output (MRIO) sectoral model. Based on the latest available data (1971–2011), indicators show a sharp dec
In heart transplantation, selection of an optimal recipient-donor match has been constrained by the lack of individualized prediction models. Here we developed a customized donor-matching model (CODUSA) for patients requiring heart transplantations, by combining simulated annealing and artificial neural networks. Using this approach, by analyzing 59,698 adult heart transplant patients, we found th
