Bioluminescence in Fishes and It’s Significance
Abstract: Living world is beautiful, Bioluminescence in fishes shows great adaptation in deep sea. Light producing organs are also called “ Luminous organs”. These organ are adaptive modifications of skin which serve to emit light in the waters, where the sunlight ceases to penetrate. It is present in deep sea fishes which occupy the region of 300-800 ft depth. It occurs in mid water and bottom dwelling deep sea fishes. Luminescent …

A Brief Review on Optical Properties of Boron Carbon Oxy-Nitride: A Phosphor for Future Era
Abstract: Phosphors are generally inorganic materials which emit light when irradiated by different sources of energy. BCNO is an inorganic phosphor containing boron, carbon, nitrogen and oxygen which is mainly synthesized artificially. Quite lately, it has gained the reputation of being an inexpensive, non-toxic and Rare Earth (RE) ion free luminescence source, which can be used to generate white Light Emitting Diodes (LEDs) with persistent luminescence properties; and for its versatile …

Application of Daylight Simulation in Detailed Design Process: Distribution of Skylights for an Office Space under Overcast Sky Conditions in Dhaka
Abstract: During design phase, architects often uncertain about the actual environmental performance of architectural details under the local climatic condition. In most of the cases architect, owner and users have to wait till the completion of the construction of the building and full occupancy to understand the performance. The building simulation software can help an architect to visualize and conceptualize the actual performance of the details and helps in decision making …

Guidelines for Day Light Design of Buildings: A Study Towards Sustainable Architecture
Abstract: Daylight provides high illuminance and permits excellent color discrimination and color rendering. These two properties mean that daylight provides the condition for good vision. However, daylight can also produce uncomfortable solar glare and very high luminance reflections on display screens, both of which interfere with good vision. Daylight strategies and systems have not always lived up to their promise as energy efficiency strategies that enhance occupant comfort and performance. One …

A Noble Approached Using NPIE MILLS Based on Underwater Image Enhancement
Abstract: ABSTRACTUnderwater Images (UI) suffers of poor visibility due primarily to properties of dispersion and absorption. Many methods have been used to restore and enhance the functionality of damaged UIs. A new approach for underwater image enhancement (UIE) is a single image solution without the need for advanced equipment or information about underwater environments or scene structure. The color compensated and white balanced (WB) version of the unique picture as inputs …

Synthesis of White Light Emitting Water-soluble CdZnS Quantum Dots at Room Temperature
Abstract: Water-soluble alloyed CdZnS quantum dots (QDs) have been successfully prepared at room temperatures by reacting a mixture of Cd(CH3COO)2 and Zn(CH3COO)2 with Na2S using thiolactic acid (TLA) as a surface capping agent. The photoluminescence (PL) spectra of the alloyed QDs are determined on the basis of the Cd2+/Zn2+ molar ratio, reaction pH, intrinsic Cd2+and Zn2+reactivities toward Na2S and the concentration of capping agent. A systematic blue shift in emission wavelength …
