Science Camp Internship Programme by KIIT group of Colleges
The morning session started at 9.30 A.M. with the lecture of Prof. Dr. S. S. Aggrawal, Director General KIIT.
He deliberately spoke on topic “Speech Science and Technology for Human- Machine Communication”. He started his talk with the simple definitions of speech defining the words as Pitch, Frequency and rhythm. He spoke that the speech of a person could tell many things as the gender, message, language, emotions and many more. He showed the graphs related to the vowels and explained how the crests and troughs are formed in graphs with the change of words depending on the pitch, intensity and rhythm of words. He explained the use of Spectrogram a device showing the characteristics of speech with the intensity of time. Our audible range is 20Hz to 20000 Hz. Voice beyond this can make oneself deaf. At low frequency high intensity is required to hear a word. If a person who could just hear the words of definite range it is called speech intelligibility which means one could gain the information through hearing. The areas of speech processing were explained including the field as coding, synthesis and speech, speaker recognition and speech translation.
Students asked many questions regarding the topic as ‘May we hear the talk that are going on inside?’ Director Sir explained that it is a part of thinking. If one could speak up the thought then it could be heard and spectrogram helps us in viewing the words.
Another student asked that ‘Why can’t we hear chips eating by others but we can hear ours?’
Director Sir answered that there is a system called internal bone conduction which helps us in hearing such voices.
After this an interesting session was carried out by Prof Maithili Sharan Ji, Ph.D from IIT Delhi and Bhatnagar Awardees. Dr. S.K. Aggarwal welcomed Prof. Maithili Sharan Ji with a Bouquet.
His topic was ‘Mathematics application to the Problems relevant to the Society’. He involved the various fields of day to day life as cricket sports, satellite, space, communication and marketing. The involvement of mathematics in the field of marketing was explained as Marketing is maths and advertising is a vital component of marketing. It does not just about understand your target audience and how to reach them; it’s about knowing how much money it takes to get your message out. It’s about data, formulas, statistics, analytics, correlations, patterns, predictive modeling and testing. The motion of objects is governed by Newton's laws. The same simple laws that govern the motion of objects on earth also extend to the heavens to govern the motion of planets, moons, and other satellites. The mathematics that describes a satellite's motion is the same mathematics presented for circular motion. Mathematics and banking are very similar in a certain way. Banks holds a huge amount of money, with any miscalculation could create many problems. So if we ever wanted to work at a bank we must have firm grasp of math skills in order to do our job well. He also well explained the application of mathematics in the medical field as essentiality of Functional numeracy to an aspiring medical professional. As a physician, perhaps the most important mathematical skills one will need are:
1. Basic mathematical knowledge sufficient to calculate drug doses, concentrations, etc.
2. An understanding of the core statistical concepts most commonly represented in the medical literature.
3. Knowledge of algebra to understand calculations of acid–base status, etc.
4. Ability to appreciate whether or not results are mathematically plausible.
Students asked questions regarding the centre of circle which was explained very clearly to them using equations. Another student asked question regarding the maths in sleep. Maithili Sharan ji explained him that various metabolic rates decrease in sleep which is a sign of mathematics involved in sleep.
After a tea break next Session was chaired by Prof. Pawan Kapoor, Adjuvant Professor at KIIT College Of Engineering, a renowned personality in the field of “Measurement Science and Instrumentation” on the topic “ Fascinating world Of Measurement Science”. He said that on a baseline level, measurements fall into the categories of weight, area, volume, length and even temperature. While we look at these various categories as stoic forms of mathematical measurements a closer examination of things we do in everyday life reveals their clear importance.
Taking proper medicine-during an illness (whether serious or minor) one need to take medicine in the proper amount. If taken too little or too much then one cannot get the proper benefit from it.
Playing sports- The importance of measurements may not necessarily reveal itself when one play sports but it is there in a big way. If one want to throw a runner out at first or make a 30 yard touchdown pass then one need to be accurate and comes from a clear sense of depth and distance.
Keeping warm or cool- If the temperature outside dips or increases we have to make an adjustment on our thermostat in order to remain at a safe and healthy temperature. Understanding the measurement scale of a thermostat is critical in this regard or else we may find you feeling rather uncomfortable.
Telling time- The ability to tell time is all based on measurement principles. Whether we are using a digital clock or an hourglass these devices measure the passage of time. Now, imagine how chaotic the world would be if it was impossible to measure the passage of time.
Transportation- How much weight is too much for a plane to take off or a car to move efficiently? How much fuel is needed to reach a certain point and how long will it take to get somewhere? Yes, measurements play a significant part in transportation.
Measurement has been a basic part of all sciences which could bring all the branches of science as agriculture, health, nuclear science together. Nature has created fascinating creations and one could nurture the nature by involvement of Science. He insisted the students to occupy the fields of Agriculture Sciences, Nuclear sciences, so that nature may be benefited by the power of technology.The students had some queries as ‘disaster like cyclone could be detected but earthquake could not?’ Sir explained that earthquake introduces two types of wave P and R wave which can be detected and one could read the frequency of earthquake on reactor scale. He also said that any natural disaster cannot be beholder. One could only try to prevent oneself.
The students then moved to lunch after which they were made familiar with the laboratories and projects in the KIIT College of Engineering. The students were divided into 4 groups
A, B, C, D irrespective of their schools. They were taken to the Chemistry, Mechanical, electronics, Computer Labs where they were given demonstration of various practicals and working of the projects. It was highly beneficial to students as they enthusiastically and keenly visited all labs and performed some of the experiments by themselves in guidance of the lab in charges and faculties. The working of instruments in labs was shown to the students preparing them for future.
ELECTRONICS PROJECT LAB: Demonstration of Electronics project based on latest technology. We gave a demo of:
i) Quad Copter- Drone (Human less machine). It is a machine based on embedded system technology. It is commonly used in various applications like video recording, disaster management information. Other projects shown to students were solar tracker system- this application using solar energy as the main resource of electricity for home, industries etc.
ii) Laser show project- Through this application various patterns are generated used for decoration in event management.
iii) Android based Robo- Line follower and obstacle avoiding robot was demonstrated. This robo used android technology for its control.
ENGINEERING CHEMISTRY LAB: The students visited chemistry lab in which the major equipment's were shown to the students as Distillation plant, muffle furnace, electric oven, electronic balance, and colorimeter. They were informed about the experiments based on different types of volumetric analysis such as acid-base, precipitation, complexometric, redox titrations and molecular weight determination of polymer using viscometric method. The major objective behind this was to make students practically realize various kinds of volumetric analysis used in testing substances like water, cement, alloys etc. Other than this they were also told about the experiments based on water analysis, proximate analysis of coal, colorimetric estimations. Students realized various steps involved in water analysis and significance of coal analysis in grading the coal, as well as application of colorimeter in medical field. The demonstration included experimentation of preparing urea-formaldehyde resin by students. They were made aware of the importance of urea formaldehyde, its formation and reaction. The students prepared the resin through the procedure as explained. They were introduced with the various equipment such as pH meter, distillation plant, TDS meter and Penskey Martin’s apparatus used in the lab.
ENGINEERING PHYSICS LAB: The students in physics lab were taught about the formation of Newton’s ring formed as a result of interference of light waves. The variation of magnetic field was determined experimentally. They were shown the experimental apparatus of Cathode ray oscilloscope through which they prepared B-H curve and studied the hysteresis loop. They were informed about the Cathode Ray tube which is the main part of Cathode Ray oscilloscope. They were also taught the Voltage/ current (V-I) characteristics of p-n junction diode which was helpful in reconciling their basis of physical sciences and the terms mentioned in their syllabus. The laboratory facilities to perform undergraduate level experiments in optics, ultrasonic, electricity, semiconductor physics and electronics were clearly demonstrated to students. Optical instruments mainly including spectrometers, mercury and sodium vapour lamps, lasers and polarimeters – which are used in the studies of interference, diffraction patterns and phenomenon of polarization were also demonstrated. The students also studied characteristics of various semiconductor diodes and other semiconductor devices such as solar cells. Several CROs, set up to synthesize nano particles and study the Hall effect.
SPORT SESSION: During the games session the students played chess, carom board, playing cards and had very memorable moments. After the indoor games the students visited Nehru Stadium after lunch on August 11, 2015. The stadium cater to several sports – like Hockey, Gymnastics, Lawn Tennis, Volley Ball, Handball, Corp Ball, Basket Ball, Football, Cricket, Athletics, Wrestling, Badminton and many others. All the pitches, courts and other sports areas have been designed as per national level standards. The students had fun and mesmerizing moments with this session.
