This study attempted to investigate the effect of sound absorption on indoor environment for infants in nursery schools. The expected effects were reduction of noise level and improvement of speech intelligibility, and consequently lowered voice level of infants, which is known as Lombard effect. Polyester fiber boards were installed on the ceilings of three classrooms of a nursery school, whic...

for installing a large number of sizes and types of items (e.g., machines) over time so as to optimize some measure (e.g., initial capital investment), subject to various resource constraints. Examples of this problem are scheduling the installation of point-of-sale terminals in supermarket and retail chains, and teller terminals in banks. We have formulated the installation scheduling problem ...

iran is ranked fourth for saline-sodic soils in asia following china, india and pakistan. therefore, if coupled with waterlogging, drainage would be an inevitable and indispensable activity agriculture in most irrigated parts of iran. drain installation depth is one of the main economic as well as environmental challenges in design and construction of drainage systems. deep pipe drain installat...

SUMMARY Wind-tunnel tests have been made to assess the aerodynamic potential of an overwing installation for fan-jet engines on a typlcal modern transport aeroplane. Low-speed tests on a complete model with free-flow nacelles and tests at higher speed on a partial model incorporating a blown jet are described; it is concluded that the lift-dependent drag associated with such an installation wou...

This paper describes an installation created by LEMUR (League of Electronic Musical Urban Robots) in January, 2005. The installation included over 30 robotic musical instruments and a multi-projector real-time video projection and was controllable and programmable over a MIDI network. The installation was also controllable remotely via the Internet and could be heard and viewed via room mics an...

Zusammenfassung Cornea Ti ist eine interaktive audio-visuelle Installation, welche für die Präsentation auf dem Lichtkunst-Festival "Luminale 2014" entwickelt wurde. Der entstandene Raum bildet eine begehbare Installation, sowie gleichzeitig eine Bühne für musikalische Darbietungen. Die Installation reagiert auf die Präsenz von Personen und erzeugt davon abhängige Lichtund Klangstimmungen. In i...

Variable 4 is a multichannel sound installation that uses meteorological sensors and a multi-layered array of algorithmic processes to transform weather data into musical patterns in real time. This paper describes the work in detail, outlining its historical context, systems infrastructure and installation specifics. The piece is discussed in relation to sonification and environmental installa...

This study aims to investigate the possibility of crime prevention through CCTV by analyzing the appropriateness of the CCTV location, whether it is installed in the hotspot of crime-prone areas, and exploring the crime prevention effect and transition effect. The real crime and CCTV locations of case city were converted into the spatial data by using GIS. The data was analyzed by hotspot analy...

Monopiles are widely used as the foundation to support offshore wind turbines (OWTs). The response of monopile-supported OWTs is strongly affected by natural frequency system relative load spectrum, and in turn, governed initial stiffness foundation. Both fatigue limit state (FLS) serviceability (SLS) design also influenced stiffness. during operational loading a function soil postinstallation,...
