  • Color Analysis Lab Report

    Introduction In color reproduction, gamut or the color gamut is a certain complete subset of colors, which can be accurately represented in a given circumstance such as given color space [1]. In another words gamut literally means the total range of possibilities that can be accomplished from red, green and blue (RGB) for a particular device [2]. If certain color cannot be reproduced accurately there is a way how to calculate the color difference by adequately describing the color by numerical values. Delta E (∆E) is the mathematical difference between two samples and is computed as distance in CIELAB space between two colors. The CIELAB color space is used as the basis of most color difference systems because the axes of CIELAB are orthogonal, color difference can be defined as the distance in three dimensional space between the coordinates for two colors [3]. The aim of this project is to find the color difference between the two displays and visualize the gamuts. In addition to that an attempt to make color match between the two displays by applying matrix based ICC profile of the phone to the laptop was performed. Matrix-based profile carries out only two computations to convert data from one color space to another. The first is a (TRC) tone reproduction curve, which spaces out the input data evenly, avoiding bunching in the light or dark regions. The second is 3x3 matrix, which is used to multiply the RGB values to convert them into CIELAB or CIEXYZ…

  • Lefloxacin Cocrystals Lab Report

    equivalent amount of the powder containing 10mg of levofloxacin, dissolved in 10mL of ethanol, shaken for 10-15 minutes and the volume was made up to 100mL using simulated gastric fluid (enzyme free) of pH 1.2. The samples were centrifuged and filtered through 0.45 µm filter, diluted suitably and analysed using UV-Visible spectrophotometer (Systronics, India) at λmax of 227nm. All observations were done in triplicate. Fourier Transform Infrared Spectroscopy (FTIR) Fourier Transform Infrared…

  • Filter Design And Harmonic Analysis In Power System

    devices. The presence of harmonics in power system is a major concern to power engineers for many years. Harmonics lead to industrial plant downtimes and power losses. Harmonic is the signal whose frequency is a multiple integer of the fundamental frequency. The highly non-linear devices are the sources of harmonics. Harmonic analysis is used to calculate the impact of harmonic producing loads on a power system [1]. The effect of harmonics on power system can be in the form of power efficiency…

  • Anionic Dye Synthesis Lab Report

    Abstract In this paper CuO-NH-NH2 nanoparticle was synthesized and used to remove anionic dyes from single and binary systems. The scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Energy-dispersive X-ray spectroscopy (EDAX) and X-ray diffraction (XRD) were used to characterize the nanoparticle. Direct Red 80 (DR80) and Direct Green 6 (DG6) were used as anionic dyes. The effect of adsorbent dosage, dye concentration and pH on dye removal was evaluated. Kinetic…

  • Comparison Between STFT And SWT

    As discussed in the earlier section, wavelet transform of the signals is recommended due to the limitations offered by STFT. AWT (Analytic Wavelet Transform) provides suitable and adaptive time-scale and time-frequency domains. Zhu [15] found better results using AWT over STFT while analyzing the noise causing human hearing loss. AWT is a type of the Continuous Wavelet Transform that calculates the product of signals and complex Morlet wavelet due to which the resulting coefficients are complex…

  • Justice In Teacher Education

    P. one student was uninterested in the activity because of the topics like superheroes, dragons, and wizards. So I went over and asked what she enjoyed and she shared about soccer. Therefore, for her I chose the genre of realistic fiction for the next round in the activity. Then had the students act out the characters they would find in a realistic fiction book about soccer. All of the students were excited and that student was smiling and engaged in the rest lesson. A small change due to…

  • Human Nature And Family Transformation In Metamorphosis By Franz Kafka

    In Metamorphosis by Franz Kafka, Gregor is not the only one who transforms but the whole family dynamic transforms due to his metamorphosis into a cockroach. Due to that transformation, there is conflict between family members particularly between Gregor’s mother and Grete, his sister. This transformation helps the readers see another view on human nature and family dynamics. From the start of the story, Gregor is transformed into a cockroach, which leads his family into conflict about how to…

  • The Hero In Eudora Welty's A Worn Path

    No matter where a person may come from, everyone encounters a similar journey. The journey that is heard in stories is symbolic to what anyone may go through in life. In the story “A worn path”, an old women goes through many obstacles as she is on the pathway to acquiring what she sought after. In order to better convey the hero’s journey in the story A Worn Path, Eudora Welty uses characterization, symbolism, and conflict. In the story characterization is used to describe the main character…

  • Chemistry In The 1800's

    Since ancient Greece, humanity has become fascinated with science. The development of new technologies that will further the existence of mankind, has been the goal for many great scientists. Through centuries of experimenting, the mid-evil era of alchemy, and many years after, Chemistry became a topic of much importance. During the 1800’s, science had become one of the most rapidly growing fields as explanations for how things work, or the technological progression allowing us to discover more.…
