Using solar screens in school classrooms in hot arid areas: The effect of different aspect ratios on daylighting levels

Hot arid areas are endowed with an abundance of clear skies. Thus, the solar energy available can significantly raise the temperature of interior spaces and also result in an uncomfortable visual environment. External perforated solar screens have been used to control solar penetration through windows. Such screens can also serve a social function, that of maintaining privacy. This paper focuses on a special case of girls’ schools in Saudi Arabia, where the privacy issue is critical due to socio-cultural and religious beliefs. Windows in girls’ schools facing public spaces are typically covered by dark opaque film to maintain privacy. This window treatment results in overreliance on artificial lighting, and in a corresponding increase in energy use. The performance of screens can be affected by many parameters, namely: perforation rate, depth ratio, shape, reflectivity of colour, aspect ratio of openings. This paper looks at how different Aspect ratios affect the performance of screens by simulating a range of cases of different aspect ratios, using the Daylight Dynamic Performance Metrics approach (DDPM). Results recommend using 1:1 aspect ratio for the south orientation whereas using different aspect ratios for the North and West orientations provide better daylight levels in the studied context

SIMULATION BASED COMPARATIVE ANALYSIS FOR THE DESIGN OF LASER TERRESTRIAL MOBILE MAPPING SYSTEMS

Over the past decade, laser terrestrial Mobile Mapping Systems (MMS) have been developed for the digital mapping of outdoor environments. While the applications of MMS are various (urban security, road control, virtual world, entertainment, etc.), one may imagine that for each application the system designs could be different. Hence, a comparative analysis of different designs may be useful to find the best solution adapted to each application. The objective of this paper is to propose a methodology to compare point-cloud data quality from different MMS designs by modifying spatial configuration of laser imaging system. For this methodology, we define several quality criteria such as precision, resolution, completeness. We illustrate this in the case of urban architecture digital mapping based on the use of a simulator

Theacher Training In ICT-Based Learning Settings: Desing And Implementation Of An On-Line Instructional Model For English Language Teachers.

Inmersos de lleno en la Sociedad del conocimiento, la incorporación de las Tecnologías de la Información y la Comunicación en los procesos de enseñanza y aprendizaje suponen un gran reto a alcanzar por parte tanto de instituciones educativas, como de un profesorado todavía poco formado y menos consciente de los cambios metodológicos a los que se enfrenta.En el marco de la formación del profesorado,la formación a lo largo de la vida se establece como prioridad en los programas educativos y de formación de la agenda europea (2007-2013) y a nuestro entender, ésta puede ser claramente ejemplificada por la creación de comunidades virtuales de aprendizaje en las que individuos con objetivos similares se unen para alcanzar retos en común. El uso de herramientas tecnológicas y de modalidades de formación basadas en entornos virtuales ayudan a la comunidad a generar e intercambiar conocimiento en un entorno en el que se participa de forma colaborativa, se comparten experiencias y se solucionan problemas, produciendo procesos de formación y aprendizaje continuos y en constante evolución.Tomando estas y otras reflexiones como punto de partida se originó la tesis doctoral que presentamos. Así pues, nos propusimos, en primer lugar, realizar un análisis de la situación actual de dicho profesorado en el uso de las tecnologías de la información y la comunicación. El primer gran bloque de esta tesis -o marco teórico y referencial- lo constituyen apartados tales como los grandes cambios metodológicos surgidos a raíz de la incorporación de las TIC y su impacto en la enseñanza y aprendizaje de la lengua inglesa. Seguidamente se realiza un exhaustivo y detallado análisis de los órganos que ofrecen formación al profesorado y a la oferta formativa en TIC dirigida específicamente al colectivo mencionado. Posteriormente se lleva a cabo una compilación de herramientas, recursos y actividades electrónicas dirigidas específicamente al profesorado de inglés teniendo muy en cuenta el ámbito pedagógico y su implantación en el aula, proponiendo pautas didácticas de fácil integración.El segundo gran bloque de la tesis lo constituye una investigación llevada a cabo durante tres años para obtener datos fehacientes respecto del conocimiento en TIC que posee dicho profesorado, la detección de sus demandas formativas reales, la situación actual de este colectivo en relación al acceso e infraestructuras tecnológicas y posibles barreras tanto metodológicas como actitudinales. Así pues se desarrolló una investigación tomando como muestra profesores tanto de educación primaria como de secundaria de todo Catalunya. Dicha investigación fue llevada a a cabo entre los participantes de ocho cursos de formación TIC para profesorado de inglés y para ello se utilizó la modalidad formativa semi-presencial. Para dar soporte a la formación a distancia se utilizaron dos plataformas diferentes: BSCW y Moodle que fomentaron la comunicación y la colaboración entre los participantes hasta límites insospechados.Los resultados obtenidos permitieron observar una realidad muy alejada de los parámetros que deberían ser considerados normales por lo que respecta al grado de formación TIC que tienen el profesorado de inglés. Por otra parte, el feedback recibido tras la realización de los diferentes cursos de formación también nos permitió realizar una propuesta de Plan de Acción formativo con el principal objetivo de capacitar al profesorado de inglés en el uso de las TIC. Así pues, se ofrece una propuesta formativa con los diferentes módulos y contenidos que, a nuestro entender, debería conocer y gestionar dicho profesorado. Finalmente, una de las revelaciones de todo el proceso fue la gestación y consolidación de una comunidad virtual de aprendizaje formada por los profesores participantes en el proceso de formación.Deeply immersed in the Society of knowledge, the integration of ICT in teaching and learning processes suppose a great challenge to be achieved both by competent institutions and by a collective of teachers, which is still far from being well-trained and not conscious of the methodological trenes and changes to which they are confronted.Within the framework of teacher training, life-long training is established as a priority in the European agenda (2007-2013) and, according to our opinión this can be exempolified by the creation of virtual learning communities in which individuals with similar objectives unite in order to achieve common goals. The use of technological tools and training modalities help the community to generate and exchange knowledge in an environment in which oparticipation is done collaborately, experiences are shared and problems are solved, producing, thus, continuous processes of learning and training, which are in constant evolution.Taking these and other reflexions as departing point this thesis was originated. We carried in the first place a detailed analysis of the present situation of English as a foreign language teachers in the use of ICT. This first great section of this thesis orreferential and theoretical basis- is conformed by chapters which deal with the great methodological changes emerged out of the integartion of ICT and their impact in the teaching and learning of foreign languages. Followingly, there is an exhaustive analysis of the different organizations which offer teacher training in ICT , especially regarding the collective mentioned. Secondly there is a compilation of tools, resources and e.activities especifically addressed to the English as a foreign language teachers, taking into account the pedagogical field as well as its integration into the classrooms.The second main section of this thesis is conformed by an investigation which was carried out during three years in order to obtain relevant data regarding the knowledge of ICT that teachers have, the detection of their training needs and the real situation of this collective regarding their access to technology and the barriers that prevent them form using ICT.Tus, we Developer an investigation which took as sample teachers belonging to both Primary and Secondary Education from the whole of the catalan territory. The research was carried out with participants of eight courses of teacher training in ICT and used the blended modality. In order to support the virtual teaching we used two different platforms: BSCW and Moodle, which encouraged communication among participants and enhanced collaboration as well.The obtained results allowed us to observe that there are many challenges to be overcome. Otherwise, the feedback obtained after the courses were delivered allowed us to account for a Training Action Plan whose main aim is that of providing training and capacitation to teachers of English as foreign language teachers

Security risk assessment and protection in the chemical and process industry

This article describes a security risk assessment and protection methodology that was developed for use in the chemical- and process industry in Belgium. The approach of the method follows a risk-based approach that follows desing principles for chemical safety. That approach is beneficial for workers in the chemical industry because they recognize the steps in this model from familiar safety models .The model combines the rings-of-protection approach with generic security practices including: management and procedures, security technology (e.g. CCTV, fences, and access control), and human interactions (pro-active as well as re-active). The method is illustrated in a case-study where a practical protection plan was developed for an existing chemical company. This chapter demonstrates that the method is useful for similar chemical- and process industrial activities far beyond the Belgian borders, as well as for cross-industrial security protection. This chapter offers an insight into how the chemical sector protects itself on the one hand, and an insight into how security risk management can be practiced on the other hand

Providing equivalent learning activities with software-based remote access laboratories

Laboratory-based learning activities are important components of engineering and surveying education and it is difficult to offering practical activities to distance education students. Remote Access Laboratory (RAL) systems are widely discussed as learning tools to offer students remote access to rigs or hardware. In some disciplines laboratory activities are purely software based and RAL systems can be used to provide access to software. As part of a larger study into the transferability of the remote laboratory concept to non-engineering disciplines this project evaluates the effectiveness of RAL based software activities in supporting student learning is investigated. In the discipline of Surveying and Spatial Science, RAL technology is used to provide Geographic Information System software access to distance students. The key research question discussed in this paper is whether RALbased software activities can address the same learning outcomes as face-to-face practical classes for software activities. Data was collected from students' discussion forums, teaching staff diaries and teaching staff interviews. The project demonstrates that students undertaking learning activities remotely achieve similar learning outcomes than student in practice classes using the same software. Ease of system access and usability are critical and the learning activity needs to be supported by comprehensive learning materials. This research provides a clear case in which the use of RAL technology has provided inclusive educational opportunities more efficiently and these general results are also applicable to experiments that involve physical hardware
