AUTOMATIC FAÇADE SEGMENTATION FOR THERMAL RETROFIT

Abstract. In this paper we present an automated method to derive highly detailed 3D vector models of modern building facades from terrestrial laser scanning data. The developed procedure can be divided into two main steps: firstly the main elements constituting the facade are identified by means of a segmentation process, then the 3D vector model is generated including some priors on architectural scenes. The identification of main facade elements is based on random sampling and detection of planar elements including topology information in the process to reduce under- and over-segmentation problems. Finally, the prevalence of straight lines and orthogonal intersections in the vector model generation phase is exploited to set additional constraints to enforce automated modeling. Contemporary a further classification is performed, enriching the data with semantics by means of a classification tree. The main application field for these vector models is the design of external insulation thermal retrofit. In particular, in this paper we present a possible application for energy efficiency evaluation of buildings by mean of Infrared Thermography data overlaid to the facade model

Metabolitos secundarios aislados de los géneros raputia y esenbeckia (rutaceae)

Las especies Esenbeckia alata y Raputia heptaphylla, pertenecen a la familia Rutaceae, estudios anteriores a especies de estos géneros dan resultados importantes, con respecto a la química de las mismas, se ha podido establecer la presencia de metabolitos secundarios que actúan como marcadores quimiotaxonómicos (especialmente cumarinas y alcaloides), además presentan actividades biológicas interesantes. Este trabajo muestra, lo más representativo que se encuentra reportado en la bibliografía para estas especies, y lo que se ha aislado hasta el momento en el laboratorio de Productos Naturales vegetales de la Universidad Nacional de Colombia, sede Bogotá

GEOMATICS AND CIVIL ENGINEERING INNOVATIVE RESEARCH ON HERITAGE: INTRODUCING THE “ENGINEER” PROJECT

This paper aims to introduce the concept and objectives of a recently supported European project entitled “Geomatics and Civil Engineering Innovative Research on Heritage”, in short ENGINEER. The ENGINEER project visions to enhance and extend inter-departmental multidisciplinary research activities of the Department of Civil Engineering & Geomatics of the Cyprus University of Technology through coordination and support actions as well as through targeted research activities with the support of European leading institutions. Project tasks aim to fill research multidisciplinary gaps, push, and extend knowledge into new and innovative fields dealing with the monitoring, digitization, visualization, and preservation of ancient monuments and cultural heritage sites, assisting their protection, promotion, and safeguarding

GENERATIVE MODELING, VIRTUAL REALITY AND HBIM INTERACTION: IMMERSIVE ENVIRONMENT FOR BUILT HERITAGE: CASE STUDY OF SHAIKH ISA BIN ALI HOUSE, BAHRAIN

The innovation in Digital Cultural Heritage (DCH) shows an emergence of innovative methods and initiatives for the generation of complex historical models to which are linked useful information for specialists of architecture, construction and engineering, but also user community interested in cultural heritage. This paper presents an improvement in Historic Building Information Modeling (HBIM) turned into models for mobile apps based on virtual reality (VR) addressed to enhance the communication of Architectural Heritage. The opportunity of a collaboration with the Bahrain Authority for Culture and Antiquities (BACA) experts under the coordination of the Carleton University in a training project aimed at improving documentation skills for conservation and preventive maintenance of built heritage provided the availability of an extraordinary richness of data and surveying on the Shaikh Isa Bin Ali House. The case study of the Shaikh Isa Bin Ali House is an outstanding example of Bahrain architecture and one of the oldest surviving building in Muharraq, listed under the UNESCO sites, now transformed in a Museum, where the visit does not allow to perceive the richness of the traditions of the constructions, beside the beautiful architecture. The building was the seat of the ruler of Bahrain from 1869 until his death in 1932 and represented an interesting response to local building materials and climate. This vernacular architecture solved not only the climate problems but combined the solution with beauty, physical and social functionality. This research carries out digital preservation through HBIM and switches to Cloud and VR platforms to allow users to enter a 3D immersive scene, using models as a vehicle of content information

Exploring the contribution of general self-efficacy to the use of self-care symptom management strategies by people living with HIV infection

General self-efficacy (GSE), the expectation that one is able to perform a behavior successfully, may differentiate those who are able to successfully utilize self-care symptom management strategies (SCSMS). This subanalysis (n = 569) of an international 12 site longitudinal randomized controlled trial (RCT) (n = 775), investigated GSE as an important factor determining symptom burden, SCSMS, engagement with the provider, and medication adherence over time, and identified differences in those with high and low GSE ratings concerning these variables. Parametric and nonparametric repeated-measures tests were employed to assess GSE and the perceived effectiveness of SCSMS for anxiety, depression, diarrhea, fatigue, nausea, and neuropathy. Symptom burden, engagement with the provider, and antiretroviral adherence were analyzed with regard to GSE. Our data indicated that there were differences in the perceived symptom burden over time of HIV infected individuals by GSE. Those individuals with higher GSE had fewer symptoms and these symptoms were perceived to be less intense than those experienced by the low GSE group. There were few meaningful differences in the SCSMS used by those with high versus low GSE other than the use of illicit substances in the low GSE group. The low GSE group was also significantly ( p= \u3c 0.001) less engaged with their healthcare providers. Given the difference in substance use by perceived GSE, and the importance of engagement with the healthcare provider, more attention to the resolution of the concerns of those with low GSE by healthcare providers is warranted
