Kong, Heng Li","doi":"10.1109/VIZ.2009.25","DOIUrl":"https://doi.org/10.1109/VIZ.2009.25","url":null,"abstract":"The use of 3D computer-aided design (CAD) models to support construction project planning has been increasing in the previous year. 3D CAD models reveal more planning ideas by visually showing the construction site environment in different stages of the construction process. Using 3D CAD models together with scheduling software to prepare construction plan can identify errors in process sequence and spatial arrangement, which is vital to the success of a construction project. A number of 4D (3D plus time) CAD tools has been developed and utilized in different construction projects due to the awareness of their importance. Virtual prototyping extends the idea of 4D CAD by integrating more features for simulating real construction process. Virtual prototyping originates from the manufacturing industry where production of products such as cars and airplanes are virtually simulated in computer before they are built in the factory. Virtual prototyping integrates 3D CAD, simulation engine, analysis tools (like structural analysis and collision detection), and knowledgebase to streamline the whole product design and production process. In this paper, we present the application of a virtual prototyping software which has been used in a few construction projects in Hong Kong to support construction project planning. Specifically, the paper presents an implementation of virtual prototyping in a residential building project in Hong Kong. The applicability, difficulties and benefits of construction virtual prototyping are examined based on this project.","PeriodicalId":315752,"journal":{"name":"2009 Second International Conference in Visualisation","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114583340","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}

Urban regeneration activities in built environment are complex and require a close collaboration between designers and planners in order to achieve a design plan that is environmentally robust and sustainable. Regeneration teams’ inability to manually analyze complex maps for various regeneration choices induces human errors in the regeneration process. This often results in a prolonged impact on the economic, social and environmental wellbeing and sustainability of the region. This paper, presents the development of an urban regeneration fuzzy inference system (FIS) aimed at tackling the issue of regeneration simulation in built environment through the measurement of impact of certain socioeconomic parameters to the regeneration plan. The impact assessment logic is embedded in the form of an expertly guided rule-base of an FIS. The impact is calculated using the four core principles of urban smart growth (crime, accessibility, employment and health), with respect to a measure of Euclidean intra-regional distance based accessibility function between the regeneration area(s) and the surrounding built environment neighborhood. The FIS evaluates the suitability of various regeneration sub-areas in terms of the aforementioned four principles affecting the concept of a walk-able, sustainable and eco-friendly neighborhood.","PeriodicalId":315752,"journal":{"name":"2009 Second International Conference in Visualisation","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116301403","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}

One of the main problems for wavelet-based compression is to overcome quantization error efficiently. Inspired by Weber-Fechners Law, we introduce a logarithmic model that approximates the nonlinearity of human perception and partially precompensates for the effect of the display device. A logarithmic transfer function is proposed in order to spread the coefficients distribution in the wavelet domain in compliance with the human perceptual attributes. The standard deviation δ of the logarithmically scaled coefficients in a subband represents the average difference from the mean of the coefficients in that subband. The standard deviation is chosen as a measure of the visibility threshold within this subband. Computing the values of δ for all subbands results in a quantisation matrix for a chosen image. A major advantage of this model is to allow for observing the visibility threshold and automatically produce the quantisation matrix that is content dependant and scalable without further interaction from the user.","PeriodicalId":315752,"journal":{"name":"2009 Second International Conference in Visualisation","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124472087","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}

For example, the increasing availability of high performance computing facilities has given the possibility to perform large-scale simulations of several dimensions. Also, forthcoming astronomical surveys are expected to collect datasets of several petabytes. The emerging need is thus for efficient visual discovery tools for rapid inspection to identify regions of interest in large-scale datasets prior to applying computationally expensive data analysis algorithms. This paper reports our experiences in developing visual discovery tools for the Sloan Digital Sky Survey (SDSS), the most ambitious astronomical survey ever undertaken. We present existing tools and visualization requirements collected from SDSS users for new functionality. We then discuss a range of newly developed visual discovery tools and their applicability to SDSS and finally we conclude with pointers to future developments.","PeriodicalId":315752,"journal":{"name":"2009 Second International Conference in Visualisation","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126650959","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}

It’s an exploration of the infinite range of colours that they have either never been able to see or that they have lost the possibility to see. The system developed is based on the concept of synesthesia: a ‘liaison’ between colour and sound, colour that becomes sound. This paper synthesizes a wider range of study regarding people with diverse psychological and movement conditions. It represents a new method of expression and of self development through music therapy and game, dedicated mainly to children aged between 5 and 13. Finally we conclude with a portable prototype device that has been validated and patented. It is capable of detecting colour and transforming it into sound: a colour sensor identifies colours and transforms this data into musical notes. The prototype is totally adaptable to the requirements of the end user meaning that the user can choose the best combination between colour and sound in order to improve their communication with the environment. We are now developing a mathematical theoretical background in order to formalize the correspondence between colour and musical space.","PeriodicalId":315752,"journal":{"name":"2009 Second International Conference in Visualisation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124978109","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}
