Three methods are suggested to identify and quantify flashback and flash forward events based on chemiluminescence recordings of swirling flames. The approaches differ in the procedure to determine the instantaneous flame position. The results revealed that the most robust method is to determine a threshold relative to the instantaneous maximum intensity. Analysis of the complete dataset indicated

A critical edition of a hymn of the Epiphany (inc. "Maria candens lilium") in the manuscript AM 76, 8o of the Arnemagnæan collection, University of Copenhagen. The text has no known parallels and is in a corrupt state. Conjectures and interpretations are offered, as well as a translation of a tentatively emendated textual shape.

The database of photographic meteor orbits of the IAU Meteor Data Centerin Lund has gradually been updated. The version 2001, which has beenprepared for distribution and which will be released soon, containscomplete orbital and geophysical data on 4581 meteors (equinox J2000.0).A new meteor identification code consisting of the publication serialnumber, the author or station code and number of the

This chapter examines the relationship between individual and organizational identity in PSFs and the significant but tenuous nature of elite identity in this context. The authors identify four main identity-related issues for management control in PSFs: autonomy/conformity tensions, the client conundrum, ambiguity saturation, and intangibility. They explore three main modes of identity-focused co

Iterative learning control (ILC) is used as a means for task execution of a time sub-optimal trajectory. The use of cascaded ILC procedures in a robot application is experimentally shown to drastically enlarge the region of convergence and efficiently compensate for unmodeled dynamics in the motion system. Objectives considered are the duration of motion, maximum liquid slosh during the motion, an

Present digital logic gates are primarily built from field effect transistors (FETs) such as complementary metal oxide semiconductors with the gate length in the deep sub-μm regime. As device feature sizes approach the nanometer regime, fundamental physical constraints and increasingly prohibitive economic costs will make further miniaturization in electronic circuits difficult, and this has motiv

The partly hot-water driven CO2 capture plant offers a significant potential for improvement in performance when implemented in a combined-cycle power plant (CCPP). It is possible to achieve the same performance with a dual-pressure steam cycle as in a triple-pressure unit. Even a single-pressure plant can attain an efficiency competitive with that achievable with a triple-pressure plant without t

To meet the constant demand for performance, it is increasingly common with multi-processor system- on-chips (MPSoCs). As these integrated circuits (ICs) may contain billions of transistors squeezed on a few square centimeters, it is difficult to ensure that they are correct. Defects may escape manufacturing test or develop during operation and, further, ICs manufactured in later semiconductor tec

In this paper we discuss parallelization and distribution of problems modeled in a constraint programming (CP) framework. We focus on parallelization of depth-first search methods, since search is the most time-consuming task in CP. The current hardware development is moving towards multi-core processors and the cost of building distributed systems is shrinking. Hence, parallelization and distribu

This paper describes a system to create animated 3D scenes of car accidents from reports written in Swedish. The system has been developed using news reports of varying size and complexity. The text-to-scene conversion process consists of two stages. An information extraction module creates a structured representation of the accident and a visual simulator generates and animates the scene. We firs

A very large majority of the current product development process models put forward in textbooks present a homogenous structure, what Ulrich & Eppinger [1] call the market-pull model, presented as a generic one, while other possible product development process models are merely seen as variants. This paper focuses on the task clarification and derived activities (mainly the systematic search f

Steady flow in axial one-stage turbines is assessed numerically and experimentally. The simulations are performed on coarse meshes using a standard numerical approach (3D, steady state, kε-turbulence model, wall function at solid boundaries). In order to allow for conclusions drawn from these rapid numerical studies, the approach was compared with an explicit LDA (Laser Doppler anemometry) mapping

This study considers detection of polyproline type II secondary structures from protein sequences. This difficult problem was handled with multilayer perceptron neural networks, which were found to be useful for such bioinformatics studies. Polyproline II secondary structures have not previously been tried to be predicted from sequences.

The objectives of this study are to review the long-term consequences of injuries to the anterior cruciate ligament and menisci, the pathogenic mechanisms, and the causes. of the considerable variability in outcome. Injuries of the anterior cruciate ligament and menisci are common in both athletes and the general population. At 10 to 20 years after the diagnosis, on average, 50% of those with a di
