In this paper, we represent an approach for combining machine learning (ML) techniques with building performance simulation by introducing four methods in which ML could be effectively involved in this field i.e. Classification, Regression, Clustering and Model selection . Rhino-3d-Grasshopper SDK was used to develop a new plugin for involving machine learning in design process using Python programming language and making use of scikit-learn module, that is, a python module which provides a general purpose high level language to nonspecialist user by integration of wide range supervised and unsupervised learning algorithms with high performance, ease of use and well documented features. ANT plugin provides a method to make use of these modules inside RhinoGrasshopper to be handy to designers. This tool is open source and is released under BSD simplified license. This approach represents promising results regarding making use of data in automating building performance development and could be widely applied. Future studies include providing parallel computation facility using PyOpenCL module as well as computer vision integration using scikit-image.

In the last few years, great improvements have been achieved in building optimization methods. Mustapha Sadeghipour Roudasri and others found new tools ” Ladybug, Honeybee and Butterfly” which could gather many simulation engines and visualization tools ” Energyplus, OpenStudio, Radiance, Daysim, CFD, OpenFOAM, etc ”. Consequently, These simulation engines will integrate with parametric modeling in Grasshopper and multiobjective optimization through Octopus plug-in to form an early stage parametric optimization framework in one canvas. This paper aims at finding the suitable plane shape and building configurations for multi-objective optimization to the daylighting levels and energy consumption of office tower building in the new administrative capital city in Egypt through parametric based optimization method. One of the most commonly used plan shapes of these types of buildings was studied. This shape and many building configurations ”WWR, window material, wall material and shading devices” were parametrically modeled. These Parameters will form many tradeoffs which will be simulated and optimized by the previous framework. Spatial Daylight Autonomy ”SDA300/50%” is examined to optimize Daylighting while Energy Use Intensity ” EUI” is used for energy consumption optimization. Multi-Objective Optimization was performed by genetic algorithms via Octopus plug-in. The near optimum design for plan shape and building configuration to balance between daylighting and energy consumption is achieved and will be a reference model for office tower buildings in this zone in Egypt which is under rapid development. The framework used in this study will guide designers to find effective solutions for early-stage design of office building in one canvas without any conflict between several engines and scripts.

The city is a complex living organism mostly affected by decisions taken whether they are political, organizational, or design decisions. Such decisions vary in scale starting with planning, urban design, and architectural scales. Urban design has been commonly agreed to occupy a hypothetical intersection between planning and architecture. It emerged to bridge the disciplinary gap between architecture and planning. Since 1960s urban design literature attempted to define what good urban design and good city form is, and the process to achieve it; yet in practice the end product doesn’t always achieve high quality in terms of urban design initial objectives. Over the last decades, the gap between disciplinary dreams in theory and real outcomes translated as urban design product of different practices has been growing in the field of urban planning and urban design. Since the urban design product does not meet its expected objectives in theory then something must be wrong with it, and a thorough investigation must come in order to perceive such gap. The Research aims to answer two main questions regarding urban design through examining the Urban Design Process; the first is whether the urban design process is capable to bridge the multidisciplinary gap? And the second question is with the little knowledge and lack of success criteria for the urban design process; how can the success of urban design be measured?

In the last years, the world has jumped rapidly towards more urbanisation, and for the first time in the history in 2008 urban population exceeded the rural population. By 2050, it is expected that two-thirds of the world population will live in urban areas. As a result of this rapid urbanisation worldwide, Sustainable Neighbourhoods SN emerged as a significant formation of cities that help in achieving sustainable development. The 2030 Agenda for Sustainable Development included this sustainability aim through the Sustainable Development Goal 11. This goal aims to “make cities and human settlements inclusive, safe, resilient and sustainable.”The Sustainable City in Dubai is located in the United Arab Emirates, the development and construction started in 2014, and 95% of the site was completed in mid of 2016. The development of the Sustainable City shows that the occupation residents will have many incentives to buy a villa and live in the city such as free rooftop solar systems, open landscaped gardens, free Green Star rated home appliances, zero net maintenance fees, and zero net service charges. Additionally, the sustainable city in Dubai is an educational hub for sustainable design. It sponsored many students through its agreements with different universities and research labs. This research aims to understand the case of the sustainable city in Dubai as an Example of SN in the Arab world. The research will start with a literature review that identifies all related terminologies to SN, besides a comprehensive analysis of some fundamental principles of SN design. A case study analysis will be done including; site visit, and applying one of the principles of SN on the sustainable city in Dubai to understand and explore the sustainability principles in it.

The largest energy consumption that we use is the consumption of electrical energy in terms of meeting the lighting needs and building air conditioning requirements (World Energy Consumption, 2016). According to the Ministry of Energy and Mineral Resources (2017), Indonesia’s largest energy use in commercial buildings is for flight systems (63%), lighting systems (20%), vertical transportation (7%) electronic devices (10%). The use of energy in the fulfillment of excessive needs result in worsening conditions on earth. Data can be a reflection of how the condition of the earth that we live at this time. Energy savings should be made to reduce the damage already occurring on this earth such as electricity usage savings, optimization of use of materials, the use of motor vehicles that cause air pollution, and others. The way that can be used to reduce artificial energy use is to utilize the existing passive building design such as the use of solar energy that can be maximized during the day, so that the use of electrical energy for lamps and artificial air conditioning. reduced. In addition, it can also be considered the optimal use of wind direction and speed that can suppress the use of Air Conditioner (AC) in excess. Building envelope with bimetal thermal material module application is part of kinetic architecture via biomimicry approach. Kinetic architecture is a concept where buildings are designed to allow parts of buildings to move without compromising the unity of the structural system. Approaches that can be applied in green building design is by optimizing bimetal material module that utilizes the thermal coefficient of a material. With this approach, building envelopes are improvised so that they can adapt to the existing environment. This research take location of case study in Kampung Juminahan, Yogyakarta, Indonesia which has characters of comunal housing.

Fracture in the adjacent levels is one of the consequences to the use of commercial poly methylmethacrylate (PMMA) bone cement. Modified PMMA with a reduced Young’s modulus was found to be safer for cancellous bone augmentation procedures. The aim of this research was to study the effect of adding hydroxyapatite (HA) nano-particles and acetone on different properties of PMMA cement. A commercial PMMA cement was used as a model for bone cement. Three groups of modified PMMA/nano-HA were investigated by adding 2, 4 and 6 wt. % of HA. Acetone as a porogen mixed with distilled water in different amounts (A/W: 1:1, 2:1.5 and 2:1g) was used to produce porous PMMA cement. The residual monomer, polymerization and mechanical properties under tension and compression tests were investigated. Young’s modulus detected from compression test decreased from 826.5±10 to 728±66 MPa by adding 6wt.% HA. Adding acetone to PMMA with 2:1.5g (A/W) has decreased the compressive Young’s modulus to 753±38 MPa. High Performance Liquid Chromatography (HPLC) measurements were carried out with intervals of 2 hours, 6 hours and 24 hours to evaluate the residual monomer for all groups. The amount of residual monomer has decreased after 24 hours of curing by adding acetone and nano-HA. Modifying PMMA by HA and acetone have inconsistent effect on the polymerization temperature. It was concluded that HA and acetone can be used to reduce the stiffness and residual monomer with enhanced biocompatibility of the commercial PMMA bone cement.

Currently, any industries face higher competition in their business pertinent to the customers' demands and product design requirements. Customer requirements and satisfaction measurement can be achieved through various methods. This paper presents an integrative framework of Kansei engineering (KE) and Kano model, applied to a product (light bulb changer LBC). KE captures and translates the emotional needs of the customer (Kansei), whereas Kano model is inserted into it to investigate the relationship between service quality attribute performance and Kansei. On this research, the integration between KE and KM in product development approach is applied though a daily life product as a case study (LBC product). The results show that the mechanical mechanism consisting of spring fingers with pvc, round grip and plastic telescopic pole is preferred by customers. This study found that the perceived or quality attributes are influenced by the emotional design or Kansei response. It provides the useful spectrum to other researchers to gain more powerful product development in the future, and stay on the customer satisfaction and requirement track.

Coal mining and washing activities in South Africa often lead to the generation of fine and ultra-fine coal which is in most cases discarded due to high handling and transportation costs. Studies conducted revealed that a large quantity of these fines have market acceptable calorific values and lower ash contents. In order to reduce fines discarded, processes have been developed to re-mine and process the fine coal discards with the aim of improving the calorific value, adding them to coarse washed coal to increase the yield as well as pelletizing the fines so as to meet the market specifications in terms of size. The goal of this study was to evaluate the efficiency of fine coal washing using gravity separation methods and comparing the products thereof to the market specifications with regards to the calorific value and the ash content. Coal fines from the No.4 lower seam of the Witbank coalfield in South Africa resulting from a dry coal sorting plant were subjected to a double-stage spiral test work, heavy liquid separation and reflux classifier test work respectively. The reflux classifier achieved products with low ash content and an increased calorific value, at high mass yields. At higher fluidization water flowrate, the reflux classifier performance was superior to that of the spirals with products of lower ash content and higher calorific value. At low cut point densities, heavy liquid separation yielded the cleanest products with very low ash content but at much lower mass yields. As the density increased, the mass yields increased with the ash content while the calorific value decreased. Most of the products from the different processes met most of the local industries’ specifications but none of them met the export market as well as the gold and uranium industry specifications due to the high ash content.

In order to reduce \u0000fines discarded, processes have been developed to re-mine and process the fine coal \u0000discards with the aim of improving the calorific value, adding them to coarse washed \u0000coal to increase the yield as well as pelletizing the fines so as to meet the market \u0000specifications in terms of size. \u0000The goal of this study was to evaluate the efficiency of fine coal washing using \u0000gravity separation methods and comparing the products thereof to the market \u0000specifications with regards to the calorific value and the ash content. Coal fines from \u0000the No.4 lower seam of the Witbank coalfield in South Africa resulting from a dry \u0000coal sorting plant were subjected to a double-stage spiral test work, heavy liquid \u0000separation and reflux classifier test work respectively. \u0000The reflux classifier achieved products with low ash content and an increased \u0000calorific value, at high mass yields. At higher fluidization water flowrate, the reflux \u0000classifier performance was superior to that of the spirals with products of lower ash \u0000content and higher calorific value. At low cut point densities, heavy liquid separation \u0000yielded the cleanest products with very low ash content but at much lower mass \u0000yields. As the density increased, the mass yields increased with the ash content while \u0000the calorific value decreased. Most of the products from the different processes met \u0000most of the local industries’ specifications but none of them met the export market \u0000as well as the gold and uranium industry specifications due to the high ash content.","PeriodicalId":33666,"journal":{"name":"ARCHiveSR","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45824567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
