An attractive and sustainable railway traffic system is characterized by having a high security, high accessibility, high energy performance and offering reliable services with sufficient punctuality. At the same time, the network is to be utilized to a large extent in a cost-effective way. This requires a continuous balance between maintaining a high utilization and sufficiently high robustness to minimize the sensitivity to disturbances. The occurrence of some disturbances can be prevented to some extent but the occurrence of unpredictable events are unavoidable and their consequences then need to be analyzed, minimized and communicated to the affected users. Valuable information necessary to perform a complete consequence analysis of a disturbance and the re-scheduling is however not always available for the traffic managers. With current conditions, it is also not always possible for the traffic managers to take this information into account since he or she needs to act fast without any decision-support assisting in computing an effective re-scheduling solution. In previous research we have designed an optimization-based approach for re-scheduling which seems promising. However, for certain scenarios it is difficult to find good solutions within seconds. Therefore, we have developed a greedy algorithm which effectively delivers good solutions within the permitted time as a complement to the previous approach. To quickly retrieve a feasible solution the algorithm performs a depth-first search using an evaluation function to prioritise when conflicts arise and then branches according to a set of criteria. © 2010 Elsevier Ltd.

We propose a modified form of the well-known non-linear dynamic equations with quadratic relations used to model a cubic nonlinearity. We show that such quadratically cubic equations sometimes allow exact solutions and sometimes make the original problem easier to analyze qualitatively. Oc-casionally, exact solutions provide a useful tool for studying new phenomena. Examples considered include nonlinear ordin-ary differential equations and Hopf, Burgers, Kortewegde Vries, and nonlinear SchroE dinger partial differential equa-tions. Some problems are solved exactly in the space-time and spectral representations. Unsolved problems potentially solva-ble by the proposed approach are listed. © 2013 Uspekhi Fizicheskikh Nauk, Russian Academy of Sciences.

Empirical Software Engineering | Year: 2014

Several factors make empirical research in software engineering particularly challenging as it requires studying not only technology but its stakeholders' activities while drawing concepts and theories from social science. Researchers, in general, agree that selecting a research design in empirical software engineering research is challenging, because the implications of using individual research methods are not well recorded. The main objective of this article is to make researchers aware and support them in their research design, by providing a foundation of knowledge about empirical software engineering research decisions, in order to ensure that researchers make well-founded and informed decisions about their research designs. This article provides a decision-making structure containing a number of decision points, each one of them representing a specific aspect on empirical software engineering research. The article provides an introduction to each decision point and its constituents, as well as to the relationships between the different parts in the decision-making structure. The intention is the structure should act as a starting point for the research design before going into the details of the research design chosen. The article provides an in-depth discussion of decision points in relation to the research design when conducting empirical research. © 2014 Springer Science+Business Media New York.

Land Use Policy | Year: 2013

Spatial planning has been earmarked as an important tool for achieving sustainable development. In Sweden the important task of planning for sustainable spatial development and land use falls largely to the local authorities, since there is no official institute for spatial planning at a national or regional level. This article investigates local planning for sustainable development by analysing recent municipal comprehensive plans, which it is argued are a major instrument for this purpose. Although comprehensive plans are statutory, their design and content is very much at local discretion, and for the most part, not a rigid process governed from above. For this reason, a template analysis was used, where the template was built from the contents of the comprehensive plans, and not from a predefined understanding of what sustainability is or how planning for sustainable development should be done. What the findings reveal, however, is that there is not much deliberation concerning the meaning(s) of sustainable development, and, further, that the planning principles considered necessary to bring about sustainable development were not exclusively regarded as sustainable as such, but rather as part of a general 'belief system' about prudent planning-sustainable or not. It is suggested that, rather than rethinking planning, planners have internalized the concept of sustainable planning into the existing 'belief system,' and thus, the planning principles have become 'sustainable' by default. © 2013 Elsevier Ltd.

Introduction: Worldwide, health systems are improving access to empirically supported psychological therapies for anxiety and depression. Evaluations of this effort are limited by the cross sectional nature of studies, short implementation periods, poor data completeness rates and lack of clinically significant and reliable change metrics. Objective: Assess the impact of implementing stepped care empirically supported psychological therapies by measuring the prospective outcomes of patients referred over a two year period to one Improving Access to Psychological Therapies service in the UK. Method: We collected demographic, therapeutic and outcome data on depression (PHQ-9) and anxiety (GAD-7) from 7859 consecutive patients for 24 months between 1st July 2006 and 31st August 2008, following up these patients for a further one year. Results: 4183 patients (53%) received two or more treatment sessions. Uncontrolled effect size for depression was 1.07 (95% CI: 0.88 to 1.29) and for anxiety was 1.04 (0.88 to 1.23). 55.4% of treated patients met reliable improvement or reliable and clinically significant change criteria for depression, 54.7% for anxiety. Patients received a mean of 5.5 sessions over 3.5 h, mainly low-intensity CBT and phone based case management. Attrition was high with 47% of referrals either not attending for an assessment or receiving an assessment only. Conclusions: Recovery rates for patients receiving stepped care empirically supported treatments for anxiety and depression in routine practice are 40 to 46%. Only half of all patients referred go on to receive treatment. Further work is needed to improve routine engagement of patients with anxiety and depression. © 2011 Elsevier B.V. All rights reserved.
