The Implementation and Design of a Multi-Reflector Cup for LED Lighting
No full textIn recent years, the luminous efficacy of light emittingdiodes (LEDs) has met energy conservation requirements.However, in lighting applications, lighting instruments must beappropriately applied to illuminate regions of interest. In thisstudy, the LED AR111 downlight was used as an example to limitbeam areas within a preset illuminating range. The TRIZ methodwas applied to generate ideas for product design concepts. Weproposed installing replaceable gratings on LED lightinginstruments, three types of multi-reflector cups that can beinstalled at various angles were designed for use in lightinginstruments, and designed multi-reflector cups within gratingsbased on compound parabolic concentrator principles forcalculating various beam angles, thereby improving thedistribution of luminous intensity by using secondary optics. The3D model and optical simulation showed that multi-reflector cupseffectively controlled beam angles, satisfied various types ofapplications for illuminated objects, and enabled the effectiveutilization of light beams. By manufacturing a lightinginstrument and measuring the distribution of luminous intensity,we ascertained that the use of multi-reflector cups in lightinginstruments effectively prevented glare. Moreover, replacing themulti-reflector cups for use at different angles enabled theilluminated object to receive favorable lighting. The componentwas verified to satisfy design requirements

The Impact of PHP Exchange Rate Movement on Export Levels from 2005 - 2014: The Case of the Philippines
Get PDFThis paper explores the effects of export levelmovements to the PHP exchange rate volatility for the period2005-2014. These two variables have been used by variousanalysts, investors, regulators and policy-makers as importantvariables in explaining the economy of countries. The paper usedhistorical monthly time series of PHP exchange rate and exportlevels in the Philippines from the period January 2005 up toDecember 2014. Stationary test and differencing methods havebeen done to address the stationarity issues of time series data.The study employed the LaGrange-Multiplier Test of ARCH Testand the Exponential Generalized Autoregressive ConditionalHeteroskedasticity (EGARCH) to test the variablesheteroskedasticity and the Granger Test for Causality in order totest the variables' causation. The results shows that, the exportlevel has no significant effects on the PHP exchange rate, and viceversa. The historical movement of the Philippine export level hasno significant causal effect on the movement of PHP exchangerate, and vice versa. The result of this study implies that theappreciation or depreciation of the Philippine peso does notprovide any benefits or adverse effects on the export level of thePhilippines and the increased or decreased level of export levels isnot an important function in the determination of the PHPexchange rate

Preservation of dangerous forensic samples of evidence with the use of mobile robotic system
Get PDFThe richest source of information about crime and criminals is the place of the incident. From the point of view of forensics the examination of the crime scene is the primary activity of inquiry and it is the core action at the scene. However, there are scenes in which conditions threaten the health and lives of investigators, e.g. an illegal laboratory of controlled substances. However, there is a need to disclose, transport and store the obtained evidence, which is a source of danger, for the purposes of criminal proceedings. Police Academy in Szczytno (Poland) conducts a research project, which aims at the development of innovative solutions and technology that will enable proper and effective protection, transport, storage and disposal of such hazardous material evidence. A solution that would eliminate these risks is a robotic system for taking samples (e.g. samples of reaction mixtures). With a view to safety of SOCOs the proposed solution is of major importance
