  • Characteristics Of Multimodal Biometric Face And Biometric Recognition

    structure to improve quality and speed of recognition. I select FFT in my project for fingerprint recognition .some time the input finger image are not satisfy the certain condition of FFT such as feature of finger image are store in database but coefficient vector of that image are larger then the pervious store image then the FFT method do not understand that image vector and not work properly. FFT is very reliable and accurate method for fingerprint recognition. I select FFT method for…

  • 1, 4-Diethoxybenzene And Neutral Benzoic Acid

    In this experiment, unknown B was a solid mixture containing two compounds of interests, 1,4-dimethoxybenzene and neutral benzoic acid. These compounds were separated by extraction and washing, and liquid-liquid extraction was specifically performed. Extraction is the process by which a compound of interest is selectively removed from impurities, and washing is the process by which unwanted products or impurities are selectively removed from the desired product. In liquid-liquid extraction,…

  • Exo And Endo-Norborneol Reaction Lab Report

    dichloromethane (DCM) was the bottom layer formed, while the aqueous layer, the layer that was washed away, was the top and this was due to the weight of the chlorine atom that made DCM more dense. Extraction was repeated several times due to the partition coefficient, as it theorizes how smaller extractions are better than bigger extractions because they yield more concentrated extractions in the end. From there, anhydrous sodium sulfate was used to pull any remaining water left and gravity…

  • Pyrazolooxazine Synthesis Lab Report

    Abstract. The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…

  • Berberine Case Study

    1 Introduction Berberine (BBR), an isoquinoline alkaloid (Fig. 1), is isolated from many medicinal herbs, such as Coptidis rhizome (Coptis chinensis Franch.) and Cortex phellodendri (Phellodendron chinense C.K.Schneid.) (1). BBR has been used to treat microbial infection, diarrhea, and other gastrointestinal (GI) diseases due to its antibacterial, antidiarrheal and strong antidotal properties (2, 3). In recent years, much focus has been put on its other potential bioactivities, such as…

  • Adipic Acid Case Study

    Adipic acid is mainly use as monomer in manufacture Nylon 6/6 fiber, plasticizer, grease, polyurethane etc. There are several countries in the world that manufacturing the adipic acid. But there also countries that just is a supplier for this adipic acid to any factory that need adipic acid in their countries. The main countries that produce adipic acid are United State of America and also China. Almost ninety percent of adipic acid manufactured in United State of America is used to produce…
