Two studies examined spatial organization reflected in searches for objects and descriptions of locations. Six-year-olds and adults retrieved objects hidden on the floors of a house or directed another person about how to retrieve them. Of particular interest was whether children's searches and directions reflected clustering of locations by floors. Six-year-olds' searches were more organized t...

There are various methods available for predicting impact sound pressure levels of floors. Understanding the accuracy of these prediction methods can be an important aspect of designing or refining a proposed flooring system. This paper provides a brief outline of some available prediction methods for massive (typically concrete) floors and light weight floor constructions. Consideration is giv...

Background: Inhalation of radon and its short-lived decay products is one of the ‎most significant sources of exposure to natural radiation. Radon is the second cause ‎of lung cancer in the populations. The present study was carried out under the projects of ‎national radon, with the aim of determining the concentration of indoor in the city of Qom ‎located in the central se...

Human comfort is recognized as an essential serviceability requirement for timber floors. Although several standards and design criteria are available designing steel concrete floors, there no consensus among researchers on the applicability of such methods to composite Adding floors intended create long spans, however, vibration still a major challenge in achieving longer spans. To highlight e...

The focus of this paper is on estimating the floor level of a robot/person moving in a multifloor environment. It demonstrates how information about transitions between floors can be employed within a probabilistic framework to improve the accuracy of floor level estimation. This is achieved by combining a simple linear classifier with a Hidden Markov Model that captures the two basic motion pa...

An analytical approach is presented to evaluate the impact of polarization mode dispersion on the average bit error rate (BER) performance of a intensity modulated direct detection (IM-DD) optical transmission system considering Maxwellian distribution for the differential group delay (DGD). The results show that the performance of an IM-DD system suffers power penalty of 0.27 dB, 0.45 dB and 2...

In order to stimulate or subdue the economy, banking regulators have sought to impose caps or floors on individual bank’s lending to certain types of borrowers. This paper shows that the resultant decision problem for a bank of which potential borrower to accept is a variant of the marriage/secretary problem where one can accept several applicants. The paper solves the decision problem using dy...

This paper introduces a novel kinesthetic interaction technique for interactive floors. The interaction techniques utilize vision-based limb tracking on an interactive floor – a 12 m glass surface with bottom projection. The kinesthetic interaction technique has been developed for an interactive floor implemented in a school square. The paper discusses the kinesthetic interaction technique and ...

This study was performed in an urban neighborhood of the capital city of the province of San Juan, Argentina. Erected as a housing complex, the place consists of 768 flats distributed in buildings of three and seven floors each. A survey was carried out in 33% of the dwellings, enquiring about the number of Triatoma infestans found indoors, stage of the bug development-nymph or adult- and how t...

Buildings with cast-in-situ reinforced concrete shear walls are widespread in many earthquake-prone countries and regions, such as Canada, Chile, Romania, Turkey, Colombia, the republics of the former Soviet Union, etc. This type of construction has been practiced since the 960s in urban regions for mediumto high-rise buildings (4 to 35 stories high). Shear wall buildings are usually regular in...
