摘要： 随着社会的发展、科技的进步,电子音乐经历了具体音乐、磁带音乐、电子音乐时期,发展至现在以计算机和交互式电子音乐为主的表演模式。与具体音乐、磁带音乐时期不一样,现今电子音乐发展成实际乐器演奏、舞蹈、视频、以及其他媒介元素的融合,形成一种多元化、多视角的表演模式。创作者运用计算机等多种端口编写和设计更多变化、更丰富的交互系统。利用传感器作为交互式电子音乐‘乐器’,不仅拓宽了交互式电子音乐的表演模式,也为创作带来了无限的可能性。本文主要探索基于传感器与小提琴交互中声音设计以及交互设计应用。

摘要： 随着环境问题的日益显现,环保部门制定了严格的排放法规,市场监管和检查也严格落实到位,尤其是到国六阶段[1][2],排放要求非常严苛,为此,柴油发动机均配备了SCR系统(Selective Catalytic Reduction选择性催化还原技术),以减少尾气中的NOX(氮氧化物)排放,其中SCR系统的添加剂就是车用尿素。车用尿素溶液为32.5%尿素和67.5%去离子水的高纯溶液,其浓度对车辆使用影响重大,直接影响车辆动力性、燃油经济性、排放合理性以及OBD监测要求,因此,需要对尿素浓度实施实时监测,检测尿素浓度的传感器就是尿素品质传感器,下文中将对尿素品质传感器作进一步分析。

关键词： diaphragm wall   joint   leakage detection   fiber Bragg grating sensor   field study  

摘要： Joints between diaphragm wall panels are weak spots in wall construction. It is essential that potential leak sites are detected prior to excavation. In this study, a novel leak detection and monitoring system is presented that is based on fiber Bragg grating (FBG) sensing technology. A field study was performed in a deep excavation supported by diaphragm walls (in Hohhot, China) to validate the feasibility and effectiveness of the proposed method. Two schemes were trialed;one using pipes made of stainless steel, and one used a pipeless method. The results of the field study are presented and discussed. They show that potential leak sites in the wall joints could be determined prior to excavation using the proposed detection method. Stainless steel is a good material to use to make the detection tube because it can protect the FBG sensors and heating belts from damage and is more sensitive to water leakage. The field study provides good evidence for the feasibility of the new detection system. It also provides valuable experience for the field application of the system and has generated useful data to use in follow-up work.

摘要： Technology innovations create possibilities to capture exposure-related data at a great depth and breadth. Considering, though, the substantial hurdles involved in collecting individual data for whole populations, this study introduces a first approach of simulating human movement and interaction behaviour, using Agent Based Modelling (ABM). A city scale ABM was developed for urban Thessaloniki, Greece that feeds into population-based exposure assessment without imposing prior bias, basing its estimations onto emerging properties of the behaviour of the computerised autonomous decision makers (agents) that compose the city-system. Population statistics, road and buildings networks data were transformed into human, road and building agents, respectively. Survey outputs with time-use patterns were associated with human agent rules, aiming to model representative to real-world behaviours. Moreover, time-geography of exposure data, derived from a local sensors campaign, was used to inform and enhance the model. As a prevalence of an agent-specific decision-making, virtual individuals of different sociodemographic backgrounds express different spatiotemporal behaviours and their trajectories are coupled with spatially resolved pollution levels. Personal exposure was evaluated by assigning PM concentrations to human agents based on coordinates, type of location and intensity of encountered activities. Study results indicated that PM2.5 inhalation adjusted exposure between housemates can differ by 56.5% whereas exposure between two neighbours can vary by as much as 87%, due to the prevalence of different behaviours. This study provides details of a new methodology that permits the cost-effective construction of refined time activity diaries and daily exposure profiles, taking into account different microenvironments and sociodemographic characteristics. The proposed method leads to a refined exposure assessment model, addressing effectively vulnerable subgroups of populati
