In this paper, a new method of inspecting pharmaceutical capsules aesthetic defects is proposed using color image processing. After an image is taken, median filtering is performed. Then the region based statistics is calculated to acquire the largest area of pharmaceutical capsule from the image. After that RGB image is transferred into R plane, G plane and B plane. Then histogram of each plane is calculated. Further by setting thresholding value of each plane, mask of each plane is determined. Color segmentation of image is achieved by combining mask of each plane. Experiments are conducted with the quality inspection of pharmaceutical capsules. Time is also taken as major parameter of the system. Experiment results show the reliability and feasibility of proposed method as time and quality control are two main parameters in industry. The proposed paper present an application to detect defect related to color of pharmaceutical capsules which can be adapted to other practical applications for automated visual inspection using image processing techniques.Keywords

Objectives: To present an overview on interfacing of MATLAB and commercial electromagnetic software packages (such as CST microwave studio). Methods/Statistical Analysis: This type of interfacing requires a scripting language interface termed as VBA script. An example for the design of an inset microstrip patch antenna is demonstrated in this paper using VBA. The controlling of CST microwave studio is done using MATLAB which calls microstrip patch antenna design along with its performance parameters such as S11 parameter, VSWR, power requirement, radiation pattern, return losses etc. Findings: The interface created between CST and MATLAB worked well and antenna parameters can be called in MATLAB to operate on them. Improvements: Further optimization algorithm can be performed on this in order to get optimized real time performance of antenna.Keywords

India has actively participated in the Montreal Protocol on Substances that Deplete the Stratospheric Ozone Layer through its noteworthy management and governance. This Protocol is an international treaty with most nations as signatories to safeguard the ozone layer. For the success of the Montreal Protocol, developing (Article-5) and developed (non-Article 5) countries, as well as those with economies in transition, need to adhere to its conditions and provisions fully. Ozone-depleting substances have been phased out from all countries. Since 1 August 2008, India has completely phased out the production and consumption of chlorofluorocarbons, almost 17 months ahead of the agreed phase-out schedule. The country has also contributed to the ‘save ozone’ efforts by all the world nationsKeywords
