The physics of the system leading to this behavior is explained, and the properties of the resulting convectons are described. The convectons are shown to be present in a parameter regime known as the pinning region containing a multiplicity of stable convectons of odd and even parity. These lie on solution branches that snake back and forth across the pinning region and illustrate a phenomenon known as homoclinic snaking. Examples of single pulse and multipulse convectons in periodic and closed containers are exhibited and compared with similar states described by the Swift-Hohenberg equation. Time-dependent states in the form of localized traveling waves are computed and distinguished from convectons that drift.

PoS(SUPERNOVA)008 Authors: Camacho Díaz, Judit; Torres Gil, Santiago; García-Berro Montilla, Enrique Abstract: We present a Monte Carlo simulator of the population of binary stars within the solar neighborhood. We have used the most updated models for stellar evolution, a complete treatment of the Roche lobe over ow episodes, as well as a full implementation of the orbital evolution. Special emphasis has been placed on processes leading to the formation of binary systems in which one of the members is a white dwarf. As a preliminary application of our Monte Carlo simulator we have performed a statistical study of the scenarios leading to type Ib supernovae events within our Galaxy Tue, 08 Mar 2011 09:55:18 GMT http://hdl.handle.net/2117/11699 2011-03-08T09:55:18Z Camacho Díaz, Judit; Torres Gil, Santiago; García-Berro Montilla, Enrique no We present a Monte Carlo simulator of the population of binary stars within the solar neighborhood.

Particularly, the practical experience is a Model Rocket Workshop (MRW), where students design, simulate, build, test and launch a small model rocket. The workshop is a Problem Based Learning (PBL) experience that covers a wide spectrum of educational aspects, ranging from theoretical disciplines, such as fluid dynamics and rocket dynamics, to topics more related to experimental work and hardware utilization like the certification of the rockets, as well as the rocket altitude measurements. Students get rapidly involved in the project, and acquire several practical and transversal abilities, while developing a solid knowledge of the physics underlying aerospace engineering. The case study shows some problems and improvements, academic results and lessons learned from the PBL approach. Finally, a series of new ideas related to MRW and the subject it belongs to are presented. The objective is to expand the MRW so that it embraces the totality of the activities that constitute this mother-subject. As a consequence, the former would then become a new subject entirely based on PBL. The strategy aims at enabling an optimum transition from conventional learning to PBL.

The model describes the feedback between waves, rollers, depth-averaged currents and bed evolution, so that self-organized processes can develop. The wave and bathymetric conditions measured at Egmond site are firstly applied and the modeled longshore current and wave height are compared with field data of that beach. Subsequently, the wave and bathymetric conditions measured at Noordwijk site are used to compare model results with the up-current oriented bars observed there. Realistic positive feedback leading to formation of the observed bars only occurs if the resuspension of sediment due to bore turbulence is included in the model. The modeled wavelength, crest orientation and growth rate agree with data but the model overestimates the migration rates.

This is done in the context of a depth-averaged shallow water model. Two physical mechanisms produce deposition-erosion patterns. Deposition either occurs where the current flows from high to low depth-averaged concentrations (1) or where the flow diverges (2). If flow conditions are quasi steady (i.e., the time scale on which bedforms evolve is much larger than the hydrodynamic time scales) only the former mechanism contributes to the formation of bottom patterns.

These professionals should also be trained so that they are aware of the current position as regards the economy and limited energy resources, and they must be creative, knowledgeable and committed if they are to rethink the current model. The Departments of Architectural Technology II and Applied Physics, in collaboration with the Interdisciplinary Centre of Technology, Innovation and Education for Sustainability (CITIES), believed that students could be given the opportunity to specialise in the area of sustainable development by means of their final theses [2]. With this objective in mind, a line of theses called Energy Assessments was created as part of the Plan for Resource Consumption Efficiency (PECR). The line was based on a learning strategy that focused on the student. The teaching staff was able to observe that, in terms of cognitive aspects, the students improved their knowledge of environmental issues and the associated skills, and that they were more able to solve problems in the area of sustainability and had greater concerns about this subject matter after having completed their theses.
