An Aggressive Search Procedure for the Bipartite Drawing Problem
1996
Graphs are used to represent reality in several areas of knowledge. This has generated considerable interest in graph drawing algorithms. Arc crossing minimization is a fundamental aesthetic criterion to obtain a readable map of a graph. The problem of minimizing the number of arc crossings in a bipartite graph (BDP) is NP-complete. In this paper we present an aggressive search scheme for the BDP based on the Intensification, Diversification and Strategic Oscillation elements of Tabu Search. Several algorithms can be obtained with this scheme by implementing different evaluators in the move definitions. In this paper we propose two variants. Computational results are reported on a set of 30…
Incremental bipartite drawing problem
2001
Abstract Layout strategies that strive to preserve perspective from earlier drawings are called incremental. In this paper we study the incremental arc crossing minimization problem for bipartite graphs. We develop a greedy randomized adaptive search procedure (GRASP) for this problem. We have also developed a branch-and-bound algorithm in order to compute the relative gap to the optimal solution of the GRASP approach. Computational experiments are performed with 450 graph instances to first study the effect of changes in grasp search parameters and then to test the efficiency of the proposed procedure. Scope and purpose Many information systems require graphs to be drawn so that these syst…
Optimal transport maps on Alexandrov spaces revisited
2018
We give an alternative proof for the fact that in $n$-dimensional Alexandrov spaces with curvature bounded below there exists a unique optimal transport plan from any purely $(n-1)$-unrectifiable starting measure, and that this plan is induced by an optimal map.
The continuing medical education Expectations, motivations and evaluations of the training experience in the Medical Radiologic Technologist
2010
Abstract Every country in the world has the obligatory program: Continuing Medical Education with the aim of maintaining a high standard of professionalism, that is in step with the times. The motivations, expectations and satisfaction that characterize, both the relational and the cognitive plan and the participation of Sanitary Technicians of Medical Radiology training CME courses, are the subjects of this study that involved 100 Radiology technicians. The results highlight areas of satisfaction and give valuable suggestions on how to plan future courses with the highest level of effectiveness.
The usefulness of the ICF framework in goal setting for students with autism spectrum disorder
2019
AbstractAn Individualized Education Plan (IEP) is a multi-disciplinary, team-developed plan that is required for a child receiving special education services. IEPs are tools for setting objectives that are responsive to students with special needs. The International Classification of Functioning, Disability and Health (ICF) is a hierarchical classification for human functioning and disability developed by the World Health Organization (WHO). The ICF classification can be used as a structural and conceptual instrument in goal setting. In this study the educational IEP objectives of five Finnish students with autism spectrum disorder (ASD) are examined within the ICF framework. The focus is i…
Influence of disulfiram on oxidative drug demethylation.
1970
In clinical antiepileptie therapy it has been observed that the simultaneous administration of diphenylhydantoin and various other drugs causes toxic reactions to diphenylhydantoin. I t was found that disulfiram (Olesen, 1966) as well as ehloramphenieol (Christensen and Skovsted, 1969) cause toxic effects in patients treated with diphenylhydantoin. They are attributed to an increased concentration of diphenylhydantoin in the plasma. Analogous observations show that chloramphenieol enhances the clinical effects of tolbutamide and dicoumarol (Christensen and Skovsted, 1969). Since diphenylhydantoin is metabolized chiefly by p-hydroxylation to 5-(p-hydroxyphenyl)-5-phenyl-hydantoin (Butler, 19…
Data analysis method for evaluating dialogic learning
2001
Abstract The purpose of this paper is to introduce a new method of analysing and evaluating dialogic learning. Dialogic learning offers possibilities that have not previously been found in nursing or nursing education, although some nursing researchers have lately become interested in dialogic nursing interaction between nurses and patients. The stages of analysis of dialogic learning have been illustrated by using an example. The data for this illustration were collected by video-taping a planning process where students for a Master’s degree (qualifying them to be nursing instructors in Finland) plan, implement and evaluate a course for nursing students, on the care of terminally ill patie…
Toward an Integrated System for Surveillance and Behaviour Analysis of Groups and People
2013
Security and INTelligence SYStem is an Italian research project which aims to create an integrated system for the analysis of multi-modal data sources (text, images, video, audio), to assist operators in homeland security applications. Within this project the Scientific Research Unit of the University of Palermo is responsible of the image and video analysis activity. The SRU of Palermo developed a web service based architecture that provides image and video analysis capabilities to the integrated analysis system. The developed architecture uses both state of the art techniques, adapted to cope with the particular problem at hand, and new algorithms to provide the following services: image …
A multimedia approach to the efficient implementation and use of emergency plans
2004
Because of the complexity of emergency procedures, the stressful situations during which they're executed, the emergency plan must be meticulously designed so that safety managers can quickly find needed information. Regardless of the complex procedures it describes and the trying situations where it would be used, the plan's success is always measured by how effective the evacuation is. Thus, safety-conscious organizations continually try to improve their emergency procedures and the way they present them in the emergency plan. Integrating incoming information during an emergency and correlating this information with the plan's procedures is a manual task for many safety managers. The dang…
Development of Municipal Solid Waste Management
2015
This paper is based on an empirical work done by author on a series of case studies such us document studies and analyzing the best practices examples. The objective of this research is to find out barriers to reach regional waste management plan demands in three municipalities: Salacgriva, Saulkrasti and Ikskile. Author gives proposal with some recommendations for development of municipal waste management as well. There are several views and attitudes of local stakeholders such us municipality, waste producers, waste collectors and mediators on how to manage collection and transportation of solid waste in practice as well as on public involvement in the process.. Passivity of stakeholders …
