TYIN tegnestue Architects. Integrating On-Site Education and Practice

Founded by Andreas Grøntvedt Gjertsen and Yashar Hanstad, TYIN tegnestue Architects grew out of an initiative to provide sleeping accommodation for an orphanage in Thailand when the principals were only third-year architecture students. Norwegian architect Lisbet Harboe explains how the student-architects built up a practice while in schools by refocusing their studies and those of their peers on learning through their own experiences of construction.     

Saliency4ASD: Challenge,dataset and tools for visual attention modeling for autism spectrum disorder

The recent studies showing that gaze features can be useful in the identification of Autism Spectrum Disorder (ASD), have opened a new domain where Visual Attention (VA) modeling could be of great help. In this sense, this paper presents a report of the Grand Challenge “Saliency4ASD: Visual attention modeling for Autism Spectrum Disorder”, organized at IEEE ICME’19, aiming at supporting the research on VA modeling towards this healthcare societal challenge. In particular, this paper describes the workflow, obtained results, and datasets and tools that were used within this activity, in order to help on the development and evaluation of two types of VA models: (1) to predict saliency maps that fit gaze behavior of people with ASD, and (2) to identify individuals with ASD from typical development.     

The International Building Physics Toolbox in Simulink

The International Building Physics Toolbox (IBPT) is a software library developed originally for heat, air and moisture system analysis in building physics. The toolbox is constructed as a modular structure of standard building elements, using the graphical programming language Simulink. To enable development of the toolbox, a common modelling platform is defined: a set of unique communication signals, material database and documentation protocol. The IBPT is an open source and available on the Internet. Any user can utilize, expand and develop the contents of the toolbox. This paper presents structure and essence of the library. Potential applications of the toolbox are illustrated through examples.     

GA优化的SVM在量化择时中的应用

针对量化投资过程中因交易信号判断不准确而导致的择时难问题,利用具有优良非线性可分能力的支持向量机建立基于历史价量信息(开盘价、收盘价、最高价、最低价、成交量和短长期移动平均指数)的量化择时模型. 在策略模型的具体应用中,为了确定LIBSVM ToolBox中的“-c”和“-g”参数,本文首先通过遗传算法对其寻优,然后利用MATLAB软件实现了对个股(浦发银行)自2012年1月4日至2016年6月22日的策略回测,最后以沪深300指数为基准从年化收益率、相关绩效指标和最大回撤等角度对回测结果进行了分析,得出GA-SVM可被有效运用到量化择时中去的结论.     

基于Toolbox的标准件库开发

在工程设计中需要大量使用标准件，而国内一些公司自行开发的国标库功能大都不够完善，不便使用。为此，我们详细分析了Toolbox的数据库结构，弄清了零件模型尺寸变量与数据库间的相互关系，并在此基础上建立了一套完整的国标库，在不需编程的情况下，很好地解决了GB标准件库的问题，文中主要分析了Toolbox数据库的内部结构，并说明了建立国标库的基本原理、方法和步骤。

Can we characterize river corridor evolution at a continental scale from historical topographic maps? A first assessment from the comparison of four countries

National historical map resources are assessed in four European countries to characterize river corridor features and associated channel changes, as well as identify issues limiting or promoting geomorphic assessment procedures at a continental scale. A geomorphic audit that launches potential data for diagnosis from reach to continental scales could offer a good resource for biology and ecology managers of river authorities or government agencies and engineers. The assessment compares the resources available by country in terms of period covered, spatial scale, history and chronology, and representation of the fluvial corridor features. We then applied the Historical Maps Vectorization Toolbox, initially developed for vectorizing river corridors from French maps, to detect and extract flow channels, unvegetated bars and riparian vegetation patches from historical topographical maps. We found that (a) it is difficult to apply an audit of channel changes to the whole continental scale because map legends differ between countries due to geographic and political specificity; (b) there exists an opportunity to get assessment information in all countries at reach or national scale where map resources are available; (c) the highest potential is observed in Switzerland and Belgium where there is high quality national map coverage from the 19th century; and (d) the algorithm Historical Maps Vectorization Toolbox applied to map resources works well with any of the countries, and its widespread application is encouraging.
