Development of a decision-support model based on fuzzy logic for optimizing of High Energy Performance (HPE) housing design in Algeria
Get PDFIn Algeria, the final energy consumption remains dominated by the housing sector, which represents 36% of the total final consumption. In 2019, the energy use increased more than 80 % from 2009. Thus, the prospects for developing the housing stock will lead to an exponential increase in this energy consumption. However, Buildings in the residential sector nevertheless have a significant potential for energy savings. In this context, the construction of energy-efficient housing is essential for controlling energy consumption in the residential sector.
The performance optimization of low-energy buildings should always take place in the early design stages when most of the critical decisions affecting building energy performance are made by integrating the optimal values of different building parameters depending on the climatic conditions. To design and construct low-energy buildings, it is essential to assure informed decision-making during the early design phases. Therefore, there is a need for the development of decision support tools that can predict the building performance and support the design decision making of low-energy buildings.
This research aims to contribute to the implementation of energy-efficient housing buildings across the Algerian territory and under all Algerian climate zones through informed design decision making in the early design stages of low-energy building. Therefore, this thesis developed a decision support model that could estimate building energy performance (cooling and heating energy loads) in early design stages without using building performance simulation tools. The model provides rapid, energy-relevant feedback, and visualize possible consequences of the design decisions.
Initially, the bioclimatic potential of all Algerian climate zones has been investigated using a dual approach that combines psychrometric chart-based analysis with building performance simulation analysis (EnergyPlus) to provide accurate bioclimatic design recommendations. Afterwards, the thermal and energetic behaviour of the typical multi-family apartment buildings, across the Algerian territory, has been evaluated using BPS techniques (EnergyPlus) combined with GIS to generate a new spatial distribution map for energy demand and thermal comfort estimation in Algeria. These maps will inform building designers without accessing, analyzing, or interpreting dense textual information.
Then, the typical multi-family apartment building design has been optimized for each climate zone using a mixed approach that combine between building performance simulation (BPS) tool (EnergyPlus) and building performance optimization (BPO) algorithm (NSGA-II). Finally, this research ends by developing a design decision-making model based on prediction using an Adaptive Neuro-Fuzzy Inference System (ANFIS) to estimate the

Comparative bioclimatic approach for comfort and passive heating and cooling strategies in Algeria
Get PDFpeer reviewedThe energy consumption and thermal comfort in buildings are heavily affected by weather conditions. Therefore, the aim of this paper is to analyze the bioclimatic potential of Algerian climate zones. This analysis was made based on eight representative locations using recent weather datasets (2003–2017). The thermal comfort and passive design potential analysis were based on a psychometric chart applying the adaptive comfort model ASHRAE 55–2017. In addition, an evaluation of the bioclimatic potential was conducted using simulations of a monitored and calibrated residential building model in Algeria using EnergyPlus. The building model has been tested in eight previously selected locations. The heating and cooling energy load results were calculated for each climatic zone and compared. The results allow architects and urban planners to better understand the climate and provide practical design guidance
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
