A convenient mapping and an efficient algorithm for solving scheduling problems within the neural network paradigm is presented. It is based on a reduced encoding scheme and a mean field annealing prescription which was recently successfully applied to TSP.Most scheduling problems are characterized by a set of hard and soft constraints. The prime target of this work is the hard constraints. In thi
The covariances in spatial models are estimated by linear smoothing of products of residuals. In the model no parametric assumptions are made about the mean function or the spatial dependence. Both are assumed to be smooth. Smoothing is based on local polynomials, though any linear smoother is possible to use. Expressions for the mean and the covariance of this estimator are developed and a versio
Measuring information systems’ (IS) impact is a long-standing topic in the research community but it is far from complete. To date, there are calls from both practitioners and academia for more contributions on this topic, especially in the area of IS effectiveness in management accounting (MA). This research is inspired by former research results that indicate that it is unclear in practice wheth

This thesis explores the long-term viability of integrating Boat-to-Grid (B2G) systems into electric marine vessels, considering technical reliability, environmental impact, and economic feasibility. Through degradation modeling, simulation-based analysis, lifecycle assessment, and financial modeling within the context of Göteborg, Sweden, this work offers a framework to understand how electric bo
This paper investigates whether political alignment between local mayors and departmental governors influences public investment decisions, specifically within the Colombian context. Using a regression discontinuity design based on close electoral outcomes, the study examines the allocation and efficiency of educational investments and related public expenditures across municipalities.

It is claimed that cytidine deaminase activity reflects local granulocyte turnover or activity in the synovial fluid of patients with rheumatoid arthritis, but cytidine deaminase is not a granulocyte specific enzyme. Lactoferrin is a granulocyte specific protein that is released from the secondary granulae during activation. We measured cytidine deaminase activity and lactoferrin concentrations in
We have implemented a non-null type checker for Java and a new non-null inferencing algorithm for analyzing legacy code. The tools are modular extensions to the JastAdd extensible Java compiler, illustrating how pluggable type systems can be achieved. The resulting implementation is compact, less than 230 lines of code for the non-null checker and 460 for the inferencer. Non-null checking is a loc
Periodontitis is an inflammatory disease of the supporting structures of the teeth and is caused by, among other agents, Porphyromonas gingivalis. P. gingivalis is very resistant to killing by human complement, which is present in a gingival fluid at 70% of the serum concentration. We found that the incubation of human serum with purified cysteine proteases of P. gingivalis (gingipains) or P. ging
Migration is a complex subject to approach in archeology and the new materials and methods available, such as isotope analysis and DNA, make it possible, and necessary, to ask new questions. The objective of this paper is to highlight the possibilities with using a new approach to migration on a population level by applying Bayesian mixing analysis of strontium isotopes. The selected case, the isl
[K+(2,2,2-crypt)] Ge-2(9)2- containing the deltahedral Zintl anion Ge-9(2-) has been isolated from a solution of K4Ge9 in ethylenediamine in the presence of 2,2,2-crypt, intended as an intermediate in mixed-cluster synthesis. The subsequent crystallographic characterisation shows the closo-Ge-9(2-) cluster unit to be tricapped trigonal-prismatic with a symmetry very close to D-3h. Each Ge-9(2-) un
2D Direct Numerical Simulations of methane/air turbulent premixed flames at initial Karlovitz numbers ranging from 600 to 9500 are performed. Instantaneous results are then extracted and analyzed with a focus on the inner flame structure. Snapshots reveal that the distributed reaction zone regime, theoretically reached around Ka a parts per thousand aEuro parts per thousand 100, is not attained be
The objective of this paper was to show the potential additional insight that result from adding greenhouse gas (GHG) emissions to plant performance evaluation criteria, such as effluent quality (EQI) and operational cost (OCI) indices, when evaluating (plant-wide) control/operational strategies in wastewater treatment plants (WWTPs). The proposed GHG evaluation is based on a set of comprehensive
Low-energy particle production perpendicular to the event plane in three-jet events produced in Z decays in e(+)e(-) annihilation is measured and compared to that perpendicular to the event axis in two-jet events. The topology dependence of the hadron production ratio is found to agree with a leading-order QCD prediction. This agreement and especially the need for the presence of a destructive int
Popular Abstract in Swedish Djupa infektioner i brösthålan (mediastinit) efter hjärtkirurgi är en allvarlig komplikation som kan ha dödlig utgång. Komplikationen är relativt ovanlig (1-3 % av hjärtopererade patienter), men de som drabbas av denna allvarliga infektion har en hög dödlighet (cirka 10-30 %). Det finns för närvarande inte någon enskild standardterapi för denna komplikation utan iställeThe aim of this research was to clinically and experimentally evaluate the use of vacuum-assisted closure in poststernotomy mediastinitis after cardiac surgery. Vacuum-assisted closure (VAC) is a new wound-healing therapy based on the application of a local negative pressure to the wound. New techniques for treating poststernotomy mediastinitis are needed since conventional techniques have an unsa
Popular Abstract in Swedish Allergisk rinit är en immunförmedlad sjukdom som huvudsakligen drabbar nässlemhinnan. Vid kontakt med allergen, t.ex. pollen, uppkommer typiska symptom såsom klåda, nysningar, rinnsnuva och nästäppa. Immunförsvaret brukar traditionellt indelas i två samverkande delar, den medfödda och den förvärvade delen. Den medfödda delen aktiveras snabbt vid en första kontakt med miAllergic rhinitis is an inflammatory disorder with the characteristic symptoms itching, sneezing, secretion and blockage upon allergen contact. In addition to the local inflammation in the nose, there is a systemic component that influences peripheral blood, bone marrow and lungs. The immune system is conventionally divided into innate and acquired (adaptive) immunity. The former is important in
Stroke is a serious neurological disease and the third leading cause of death in the western world. In roughly 15 % of the cases, the cause is due to an intracranial haemorrhage, and the remaining 85 % represent ischemic strokes. Ischemic stroke is caused by the occlusion of a cerebral artery either by an embolus or by local thrombosis. Several studies have shown an involvement of the endothelin s
