This paper analyzes the effects of daylight and daylight saving time (DST) on pedestrian and motor vehicle occupant fatalities in the United States. Multivariate analyses of county level data from the Fatality Analysis Reporting System for 2-week periods in 1998 and 1999 are used. Results show that full year daylight saving time would reduce pedestrian fatalities by 171 per year, or by 13% of a...

In this paper we discuss the support provided by parametric modeling and genetic algorithms to performance oriented design processes; the topic is discussed and exemplified with specific reference to modular wide span roofs. First, the paper introduces the concept of performance oriented design and describes potentials and limits of parametric modeling in supporting the process. Among the poten...

A lightpipe is an about 99 percent specular reflective mirror pipe or duct that is used for the transmission of the daylight from the outside into a building. The lightpipes are usually used in the daylighting buildings, in the residential, industrial and commercial sectors. This paper is about the performances of a lightpipe installed in a laboratory (3 m x 2.6 m x 3 m) without windows. The ai...

This paper provides an overview of theory and research on the human benefits of building design. Identified benefits include improved health outcomes, psychological well being, reduced stress, improved cognitive performance, and improved work and life satisfaction. While many building variables affect these outcomes, there is growing evidence that the high impact design features are connection ...

Introduction: We present recent developments in instrumentation for in situ planetary time-resolved Raman spectroscopy, leading to improved performance and identification of both minerals and organics. The Time-Resolved Raman Instrument shown in Figure 1 builds on the widely used 532 nm (green) laser Raman technique, but uses time resolution to detect Raman spectral signatures while eliminating...

conclusions recent treatment, in addition to age, gender and daylight duration were proved as strong independent determinants on bat development and the level of metabolic activity at [18 f] dg pet/ct and should be considered as an important confounding factor in future researches. results one-hundred eighteen studies were recognized to demonstrate foci of fdg bat uptake (3.1%, mean age: 22.7 y...

of photodiode and transimpedance amplifier on a 12.4 Moisture Sensitivity and Soldering. narrowly-focused beam falling only on the photodiode provides improved settling times from allanalog circuits to data conversion base circuits. Q1 and Q2 form a "cascode" amplifier circuit. To compensate for the high-frequency rolloff of the photodiode, U1B is configured as Daylight modifications will drama...

Seasonal blood pressure (BP) changes have been found to be related to either outdoor or indoor temperature. No information regarding the independent effects of temperature measured proximally to the patient, the personal-level environmental temperature (PET), is available. Inclusion of daylight hours in multivariate analysis might allow exploring the independent interaction of BP with seasonali...
