The quality of diverse compound selection mainly depends on cluster algorithms, descriptors, the combinations of the descriptors, and similarity metrics. The Jarvis-Patrick algorithm, MDL search keys, and Daylight fingerprints are a well accepted algorithm and structure descriptors for compound library diversity analysis. Based upon our 288 experiments on selecting compounds from various descri...

Repeated modifications of multiple design parameters are required to optimize daylighting system design. However, a large number of optional design parameters increase the computation time. This research developed a simulation-based model to evaluate daylighting system design based on system daylighting and thermal performance. The model utilized the prediction methods to speed up computation. ...

BACKGROUND This paper investigated the effect of daylight on morning and night melatonin, subjective general health using GHQ questionnaire, sleepiness and alertness on elderly who lived in nursing houses. METHODS Nineteen nursing home residents participated voluntarily. They exposed to daylight from 9 to 10 a.m. and from 4 to 5 p.m. for 6 wk. The level of melatonin in the morning and at nigh...

Here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (TEA) and zinc acetate. The ZnO nano particles (NPs) were formed and stabilized on the fabric surface by amine compound at 130 °C for 1 h. The synthesis of nano ZnO particles on the polyester fabric were confirmed by X-ray diffraction (XRD) pattern...

Abstract In a built space, the visual comfort is an important factor. It depends on exterior environmental conditions. general, daylight has positive effect human behaviours and circadian rhythm. Also, occupants with great connect outdoors achieve high productivity. The tend to use shading devices based local conditions not future weather this background, kinetic facades provide higher degree o...

A deep-plan office building design limits daylight access on the workspace distant from side window. Horizontal Light Pipe (HLP) is one of light transport systems that can deliver to these areas. The research aim was explain and evaluate effect HLP’s opening distribution area performance at deep plan-private space. method experimental with simulation as a tool. Daylight level base case, HLP an ...

Daylight, rather a fact than a matter of discussion for many millennia, has lost its dominant role in architecture during the years 1950 till 1965. The artificial lighting of interiors had reached its long promised goal and was considered superior to daylighting in quality. In many countries, office buildings and even schools were built without windows because the new techniques of lighting and...

This paper describes a proof-of-concept implementation that uses a high dynamic range CMOS video camera to integrate daylight harvesting and occupancy sensing functionalities. It has been demonstrated that the proposed concept not only circumvents several drawbacks of conventional lighting control sensors, but also offers functionalities that are not currently achievable by these sensors. The p...

Plant responses to the light spectrum under which plants are grown affect their developmental characteristics in a complicated manner. Lamps widely used to provide growth irradiance emit spectra which are very different from natural daylight spectra. Whereas specific responses of plants to a spectrum differing from natural daylight may sometimes be predictable, the overall plant response is gen...

As people increasingly work in indoor environments, the need to provide natural lighting is becoming more widely recognized. Recent modelling standards such as LM-83 require the use of climate-based metrics based on daylight coefficients, rather than illuminance-based metrics that simulate single points in time. While calculations based on daylight coefficients are fast, computation of the dayl...
