One week Internship Programme on ‘Practical Approach to the field of Electronics

As a part of the in-house training for BE-ETC students, the ETC Department of Don Bosco College of Engineering, in association with DBEATS Council, organized a ‘One week internship programme on ‘Practical Approach to the field of Electronics’ from 8^th to 12^th Jan, 2018.

The Internship programme started with a one and a half day session on “Schematic and Layout using OSCAD” on the 8^th and 9^th of January, 2018. The sessions were delivered by Prof. Flavia Leitao and Prof. Mathilda Colaco. First day’s sessions began  with an introductory and interactive talk on “PCB Design” explaining the different stages involved in PCB designing, the different packages,  holes and surface mount techniques along with  soldering methods. Hands-on training session on OSCAD exposed the students to the different OSCAD editors and builders, drawing of Schematic in Schematic editor, generating Netlist, mapping footprints in Footprint editor and finally drawing the Layout in Layout editor. The following contents were covered during the morning session of second day: testing the circuit on breadboard, transferring the Layout from OSCAD onto the PCB, masking to remove the unwanted copper, etching, drilling and mounting of components, soldering, testing.

The afternoon session was delivered by Prof. Trima P. Fernandes e Fizardo on “Introduction to Cryptool 2.” Hands-on Session was conducted on Cryptool 2.0 software where Algorithms such as Julius Caesar Cipher, Transposition Cipher, RSA Algorithm for Encryption and Decryption, DES Algorithm for Encryption and Decryption were implemented. The session concluded with various applications of Cryptography.

On the third day there were sessions on “Design and Analysis of Microwave Components”. It began with Introduction to Microwave Engineering by Prof. Mohini Naik where the Students were made familiar with design of simple micro strip line, Quarter wave transformer & T – Junction Power Divider. Thereafter, Prof. Yeshudas Muttu introduced the students to implementation and analysis of Microwave Components like Rat race coupler and Hybrid coupler. This session was extended with optimization of those components to achieve better results.

On the 11^th and 12^th of January the sessions were delivered by Prof. Melba D’Souza, Prof. Deron Rodrigues and Prof. Vishnu Rathod on “Advances in Digital Image Processing”. It commenced with a technical session on Introduction to key stages in Digital Image Processing, by Prof. Melba D’Souza. This was followed by hands on session using MATLAB on fundamental modules and different applications of Image Processing. Prof. Deron Rodrigues gave valuable and basic information on image formation, image resolution and different image enhancement techniques. MATLAB programs to Import, Export, and Convert Image class and types were implemented, followed by MATLAB codes to implement Image Arithmetic, ie. Addition, subtraction, multiplication, and division of images. Basic Image Transforms used in Image processing, Basic Geometric Transformations which include cropping, resizing and rotating images were covered.
On the last day, Prof. Deron Rodrigues delivered sessions on ‘Image Enhancement’ which consisted of Contrast adjustment, histograms and histogram equalization and other image enhancement tools. This was followed by session on ‘Image Restoration’ by Prof. Vishnu Rathod, which covered MATLAB codes for creation of blurred images, de-blurring of images, creation of noise images and de-noising of images. In the afternoon session, Prof. Vishnu Rathod explained ‘Video Processing’ which included implementation of codes to display a video clip in MATLAB, acquiring frames from video. This was followed by Prof. Deron Rodrigues on Morphological Filtering which included Dilation, erosion, reconstruction, and other morphological operations.
