Problem 3

Shielding Effectiveness of Fabric

Mr. Dinesh Chudasma
Dr. Satyajeet Chaudhari

The trend in today’s electronic devices is faster and digital rather than analogy. Any electrical apparatus such as high voltage power lines, radar, communication system, radios, televisions, household appliances, computer, mobile phones etc generates electromagnetic waves. Electromagnetic waves are also known as EM waves that are produced when an electric field comes in contact with the magnetic field. The high-tech products not only bring us convenience but also many negative effects. These electromagnetic waves create electromagnetic interference to the electrical circuits and also affect human health. When electromagnetic waves enter the human body, it will destruct cell’s regeneration of DNA and RNA. Furthermore, it causes cancer, brain tumour, heart attack and skin diseases etc. Electromagnetic Interference is encountered by all of us in our daily life and are expected to face exponential rise in future due to the growing number of wireless devices and standards including cell phones, GPS, Bluetooth, WIFI, etc. Electromagnetic Interference (EMI) is the disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source. This disturbance may interrupt, obstruct or degrade the effective performance of circuit. The simplest way of protection from electromagnetic waves is to stay away from it but this is not always possible. The most effective method of protection from electromagnetic waves is shielding or electromagnetic shielding. Shielding is typically applied to enclosure to isolate electrical devices from the outside world and cable to isolate wire from environment through which the cable runs. Electromagnetic shielding is a conductive barrier that completely envelops a device to protect from environmental interference or to stop emission from the device itself interfering with other devices. In other words, electromagnetic shielding is the practise of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. Motivated by the increase of stress over electromagnetic pollution issues arising from the fastgrowing development and need for electronic and electrical devices, the demand for material with high electromagnetic interference shielding performance has become more urgently. The common material used for construction of enclosure for shielding is metal such as copper, brass, aluminium, silver, nickel, stainless steel etc. Although such material has good shielding performance but it has some disadvantages like low elasticity, heavy weight, high costs, easy to corrode etc.

So, there was a need of material which is light weighted, flexible, corrosion resistant and cheap. Textile material fulfils all these requirements. But textile materials are electrically nonconductive. So, it was necessary to make it electrically conductive. These are various methods available for imparting electrical properties to textile material such as magnetron sputtering, coating of fabric with metal, incorporating conductive fibres or yarns in fabric etc. In the experiment, a commercially available polyester-cotton blended fabric is chosen and to make the fabric electrically conductive, its surface is coated with silver metal using magnetron sputtering technique.

Three different silver coated samples of thickness 1, 3 and 5 micro meter are prepared and tested as per the ASTM D4935 method. From the experiment it was observed that shielding effectiveness increases by increasing the thickness of coating.

At present there is no mathematical model and simulation is available for this electromagnetic shielding effectiveness. Now performing the experiment every time will be costly and time consuming. So, mathematical model and simulation will avoid the actual experimentation. Therefore, we want to model the electromagnetic shielding effectiveness using experimental data and validate the model.

In today’s world, Millions of websites are being targeted everyday by Cyber Criminals with the motive to get the Social or Financial benefits out of it. Data Exfiltration has become biggest issue in the world of Cyber Security. It is very important for us being a Cyber Security company to understand and differentiate between “GOOD” and “BAD” Cyber Traffic. In nutshell, when Cyber Criminals tries to Exfiltrate data out of the websites they target, they use specific grammar strings as an attempt to compromise/deface the websites. it is next to impossible to perform sampling of billions of web-request with Human intelligence and identify how “GOOD” traffic looks (used by legitimate users) like and how “BAD” traffic looks like (used by Cyber Criminals).

The only possible way to produce set of “GOOD” and “BAD” traffic (grammar strings) is to develop mathematical models through Autonomous Learning and forecasting. When we say “Positive Security Model”, it is a set of grammar produced by learning habits of “GOOD” user’s behaviour and always allowed to pass through over the website, rest all will be considered as “BAD” traffic and blocked. On the other side, the biggest problem with Autonomous Learning is introduction of False Positives which have to be addressed in a smarter way by using Anomaly Scoring mechanism to avoid catastrophes. We can split the problem into two separate Tasks. In first Task, we can work on generating raw character patterns (raw datasets) and in Second Task, we can construct Regular Expressions (REGEX) from the first Task derived patterns with appropriate string formation.

Developing an Isothermal Testing Chamber Facility

Dr. Satish Chetwani, Research Director,ERDA
Mr. Nilesh Karkare, ERDA

ERDA (Electrical Research & Development Association) is one of the most modern centers for Research & Development, Certification & Calibration of electrical products. It was established in 1974 in Vadodara at Makarpura Industrial Estate. It is a co-operative research institution created by the Indian Electrical Industry and utilities with the support of Government of India & Gujarat. It is a not-for-profit sector co-operative organization. It has country’s largest online Emphasis.

ERDA is credited recognized as ISO-17025 certified laboratory. It equipped with the advance infrastructure to meet National and International standards. It has 5000 domestic as well as international customers every year. ERDA operates premium laboratory for switch gears and control gears. Its laboratory has country’s largest IP Test facility. ERDA has also three laboratory sites across India, ERDA(North) at Gurgaon, ERDA(West) at Rabale, and ERDA(South) at Rajamundry to serve the customers across various geographical locations of India.

ERDA’s R&D division has developed, improved, and commercialized several award winning Technologies like On-line Fault Sensor, DCMCB, Fault Current-meter, LED based manual rechargeable Lamp & new Polymeric material for wiring accessories with a respectable IPR portfolio.

Recently, ERDA working on project related to a Heat Chamber. There are several Heat Chambers available in commercial market but the Chamber on which ERDA is working on has a curious requirement. A gulf country, Dubai, requires continuous operation of the Test Chamber at a temperature of 55 degrees Celsius by 12 hours without deformation of Test Chamber and any part of Chamber and accessories with some restrictions and requirements such like,

1. No external influence of air from outside the Chamber affect the performance and inside temperature. That is an air tight arrangement is the preferred mode.
2. The chamber should be collapsible and self-supported.
3. A suitable control panel must be designed with protection system for individual control of the heating arrangements.
4. Warranty period of this Chamber should be of 1 year.

• • Requirements for the Heat Chamber:
    1. Dimension of the Chamber:
    2. Width –    0 meters.
    3. Depth  –    5 meters.
    4. Height –    0 meters.

Temperature Range:

1. Ambient temp. inside the chamber up to +55°C.
2. No temperature difference within the chamber of more than 2°C.
3. Uniformity of the temperature inside the chamber shall be verified by 9 point calibration method.

Heating System:

1. Stainless steel finned type heaters shall be used to achieve the temperature.
2. Positioning of the heater shall be such that there is no direct radiation from the heater on the test specimen.
3. Possible heating from the test specimen can be up to a maximum of 5 kW.

Refrigeration System:

The refrigeration system shall be provided near the room with suitable ducting etc. high capacity hermetic compressor on anti-vibration pad using eco-friendly non CFC refrigerant shall be used. Suitable heat exchanger with suitable coaxial fans shall be used for cooling.

Air Circulation:

The refrigerator compartment shall be separate from the chamber. A separate conditioning chamber shall have the cooling coil (Heat exchanger) and the heater system.  The Air in the chamber shall be recirculated after conditioning.  The air delivery shall be restricted to a minimum of 0.5 m/Sec.

Although there are several restriction and requirements for the Chamber but the major thing is to maintain the temperature which is surrounding the computing equipment (referred to as the ambient temperature) in the Chamber. This problem seems similar to the Thermal Power Plant. So inspired by the cooling arrangement of Thermal Power Plant, the radial fan has located at the top of the Chamber. By this arrangement we will have the uniform velocity of air in the Chamber. Since air velocity criteria is 5 m/s. By increasing the diameter of the fan we will achieve the velocity requirement and uniform temperature distribution in the Chamber.

Problem 4

Optimal Cutting and Wastage in Fabric

Mr. Manan Desai, CEO
Tech Shivam Industry, 791, G.I.D.C., Makarpura, Vadodara – 390010

When fabric is made there are some fabric defects left in it. The location and type of these defects can be determined by inspection of the fabric. The fabric is made in a very large size and need to be cut for delivery to clients. The clients have different requirements and, in particular require different quality of fabric, so are willing to accept different numbers of defects. The basic question is how to cut the very large manufactured lengths of fabric in such a way that the clients’ orders at filled but company has minimum wastage of fabric?

When cutting fabric, there are some restrictions:

1. Cut piece of fabric may not have length more than 140 meters (workers cannot move pieces of more than 140 meters the because of its weight) and pieces must not be less than 70 meters
2. Any cut pieces which are less than 30 meters length will be waste.
3. Number of defects which we can allow in one cut piece of fabric depends on client requirements. They may specify good fabric quality, or average quality fabric. So the company wants to create a program which, takes as inputs the location of defects in the fabric and the client requirements, and gives as an output where cuts should be made in fabric such as there is minimum wastage of fabric.

Problem 5

Gridded Climate Data for Local Scale

Dr Sanskriti Majumdar
Mr. Chirayu Pandit
Institute of Climate Change Research

The IPCC Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation gives a definition, stating that “an extreme (weather of climate) event is generally defined as the occurrence of a value of a weather or climate variable above (or below) a threshold value near the upper (or lower) ends of the range of observed values of the variable”.

Extreme rainfall, temperatures have direct effects on various fields like health, agriculture, water resources etc. Flash floods in urban area are the result of extreme rainfall which affects infrastructure, health and economy of the city.

Most of meteorological/climate data available through different agencies/institute are in gridded format like General Circulation Model (GCM), TRMM.

It is noted that when doing extreme rainfall analysis to study the behaviour of changes in the extreme events, using real or actual station data is more realistic than the gridded data. In particular, when using gridded data extreme events will be missed in most of the occasions due to interpolation or averaging scheme used in gridding. This can then give misleading information regarding the signals of hydrological extremes needed for better disaster management.

It is also found that Gridded data performs well at country level and regional level but when it comes to local scale or micro scale problems, like at urban administrative boundary level, there are more uncertainties in performance of the models.

Objective

• How to preserve extreme values in methods of gridding and downscaling and interpolation.
• How to enhance ‘performance’ of Gridded datasets at local scale

 In-Situ Metrology of Medical Devices

Mr. Sudhir Nambiar
Adaptive Ocular Sciences Pvt. Ptd.

plot no : 11,chandradeep industriul est.,NR, Chitra Gujarat Industrial Development Corporation, Bhavnagar, Gujarat, India

Contact lenses and foldable Intra Ocular Lenses are medical devices that need to be machined in a DRY state (Single Point Diamond Turning of Hydrophilic Acrylics HEMA). These are then hydrated in normal saline to make them soft. This process of hydration results in the dry parameters of the lens, like radius of curvature (power) and thickness of the lens getting altered due to the uptake of saline.  The swelling of the lens is dependent on multiple factors but mostly on the linear and radial expansion factor of the material being used.

The industry is faced with a challenge of measuring the dimensions of the lens namely its CT (Center Thickness). ET (Edge Thickness) and Radius of Curvature in a liquid (saline) medium. These lenses tend to dry out fast if taken out of saline thus altering their dimensions. The soft nature of the lens is not conducive to contact measurements as this can result in wrong readings.

A possible method that could be used to avoid these measurement difficulties is to develop an OCT system that can measure these parameters inside a saline medium like a cuvet / bath. The resolution should be within a micron or two to make the measurement useful. Measurement range is between 40 to 1500 microns. Area of interest is within 14mm. Sag varies between the two medical devices. Contact lenses have a higher Sag compared to Intra Ocular Lenses.
