Life with IoT: In just one year alone, we went from having 5 million IoT devices connected to the internet to billions. The future is happening now, and these devices are getting smarter every day through machine learning and artificial intelligence. IoT devices are becoming a part of the conventional electronics culture and people are adopting smart devices into their homes faster than ever. It is estimated that there will be up to 21 billion connected devices to the internet. IoT devices will be a huge part of how we interact with everyday objects. There is big money in the IoT space currently, and it will only continue to grow as technology improves. The more data that IoT devices collect, the smarter they will become. Cities will transform into Smart Cities through the use of IoT connected devices. Think of Smart Traffic Lights that collect data on traffic, and use that data to synchronized lights to peak traffic times. Overall, this improves cities overall efficiency and saves the government money since everything can be remotely managed. Smart homes, thermostats, lighting systems and coffee makers will all collect data on your habits and patterns of usage. All this data will be collected to help facilitate Machine Learning. How do we security to these devices? With the billions of IoT devices connected to the open internet, how do we ensure these devices are secure? Encryption Scheme: AES vs. TLS/SSL Encryption can solve a complicated problem. When people think about encryption, many will turn to TLS/SSL, however, these protocols don’t cut it for encryption and processing. The reason these protocols aren’t optimal is they are point-to-point solutions and not end-to-end solutions. When data has to go through many different points on the chain, we are going to have to account for different security protocols and devices. This requires a security solution like AES (Advanced Encryption Standard) since it provides end-to-end security, and encrypts the message all the way through. Only devices with the encryption keys can decrypt the encrypted data as it’s sent and received. AES also allows you to wrap the message body with AES and leave all the actionable data in TLS. Actionable data, for instance, would be temperature information that you are trying to read. In addition, we need to prevent all inbound ports from being open at all costs since this can leave your IoT devices open to vulnerabilities and DDOS attacks. Devices should only make outbound connections, so that way the door is closed to accessing applications and services behind those open ports. The connection outward can be left open so the device can listen in with a secure tunnel back from the network
The idea of E-Learning During COVID-19
The idea of customary training has changed drastically inside the most recent few years.
Being genuinely present in a study hall isn't the main learning alternative any
longer — not with the ascent of the web and new innovations, in any event.
These days, you approach quality training at whatever point and any place you need,
as long as you approach a PC.
We are presently entering another time — the transformation of online training.
1. It's adaptable.
Online instruction empowers the instructor and the understudy to set their own learning pace,
and there's the additional adaptability of setting a timetable that accommodates
everybody's plan. Therefore, utilizing an online instructive stage takes into account a
superior equalization of work and studies, so there's no compelling reason to surrender
anything. Examining on the web shows you imperative time the board aptitudes,
which makes finding a decent work-study balance simpler.
2. It offers a wide determination of courses.
In a space as huge and wide as the web, there are unbounded abilities and subjects
to educate and learn. Online stages offer courses for different levels and teaches, and
the developing prominence of online instruction has prompted an ever-increasing
number of courses blasting onto the scene. From guitar exercises to quantum material
science, there are possibilities for each kind of understudy. There's likewise an
extraordinary opportunity to get official declarations or substantial recognitions.
Thusly, understudies can even get a degree without going to a college grounds.
3. It's open.
Online instruction empowers you to study or educate from anyplace on the planet.
This implies there's no compelling reason to drive starting with one spot then onto
the next, or follow an unbending timetable. What's more, in addition to the fact that
you save time, yet you likewise set aside cash, which can be spent on different needs.
The virtual study hall is likewise accessible anyplace there's a web association, and a
decent method to exploit this is to travel. For instance, in case you're concentrating
abroad and need to find a new line of work, online training is an extraordinary
decision. There's no motivation to abandon working or examining while at the same
time investigating new and intriguing spots.
4. It takes into consideration a tweaked learning experience.
We've referenced before how adaptability enables the understudy and the instructor to
establish their own tone .Be that as it may, online training is additionally adaptable for
every understudy's prerequisites and level of capacity.
Online classes will in general be littler than ordinary class size.
5. It's savvier than conventional training.
Dissimilar to in-person instruction techniques, online training will in general be
progressively reasonable. There's additionally a wide scope of installment choices
that let understudies pay in portions or per class. This takes into account better spending administration.
Concept of Learning by GEC WRITHLON on Thursday, March 26, 2020 in MECHANICAL Learning is a procedure that-produces changes in the conduct (behaviour) of the person. These conduct changes happen because of encounters (practice). These changes can take any direction. These conduct changes are generally perpetual. This means that these changes are not completely permanent or are they altogether temporary or permanent. These conduct changes are called learning. An individual learns and establishes harmonious alteration with the earth. This is the genuine significance of learning. As a rule, realizing something new is called learning. A baby is completely powerless at the hour of birth. He relies upon his folks for the satisfaction of his needs. As he grows up, his tangible forces start to create. He encounters numerous issues in his push to acclimate to the earth. He responds to these issues in various manners. In the process he picks up understanding. These encounters produce changes in his conduct. These progressions are generally perpetual. These conduct changes are called learning. For example a child sees the light of a lamp for the first time. Out of curiosity he catches at the flame. He feels a burning sensation. As a result he withdraws his hand from the flame and does not repeat the act in future. It is a natural reaction to become curious on seeing the flame and catching at it. On the basis of this natural reaction the child gains experience that catching at a flame causes burn. The next time when he sees the light of the lamp, he does not react the way he did the first time. This behavioral change has occurred as a result of experiences. The child has learnt that catching at the flame causes burn therefore; learning means change in the behavior through experience. Changes in the conduct of an individual lake place because of experiences. Experience here methods an occasion or movement that has influenced one here and there. It additionally implies the things that have transpired over some stretch of time that impacts the way one thinks and carries on. For instance social changes might be brought about by old sickness, yet this isn't called learning. Just the conduct changes that come about because of experience or practice are called learning. The conduct changes that come about because of learning are moderately bearing; this implies that the progressions are not totally lasting. Nor they are transitory or passing. These progressions are found in the conduct for a moderately significant stretch. These progressions are not as perpetual as won't clear a path for more changes; new changes in conduct can be concentrated by differentiating the conduct of the accomplished individual with that of the unpracticed individual. These behavioral changes may happen in any course meaning their impact might be certain or negative, Learning adds to one's proficiency. Given Beneath are some meaning of discovering that makes its significance and idea clear: According to A.T. Gates – 1946 – “Learning is the modification of behaviour through experience and training.” Views of H.W. Bernard- 1952 – “Learning is the modification of behaviour through activity and experience which improves modes of adjustment.” Views of kingsley, H.l. and Garry R- 1957- “Learning is a process by which behaviour is originated or changed through practice.” Views of Pressy , Sidney, l- 1959- “ learning represents experiences that lead to a change or adjustment in performance and to the acquisitions of new ways of behaviour.”
Robotics by GEC WRITHLON on Wednesday, April 01, 2020 in ELECTRONICS, MECHANICAL Robotics, in various forms, have been in the minds of humans since we were able to build Things. You can see machines made by artisans trying to mimic human movements and behavior. Examples include the statues of Venice's San Marcos Clock Tower Hit the clock by the hour and the figures tell a story of the fifteenth century astronomical clock toward the Old Town Hall Tower in Prague. Sophisticated machines with repetitive movements from toys, simple types are other examples. In Hollywood, movies also portray robots and humanoids superior to humans. E:\BLOGS\nyisvytle5tg3lim6tbq.jpg Humanoids are in principle robots and are designed and operated by the same basic concepts. The elements used in robots and robotics are actuators, sensors, vision systems and so on. Robot Rovers are no different usually has low degrees of freedom and usually moves in flight. Exoskeleton and Humanoid robots, walking machines and robots that mimic animals and insects may have several degrees of freedom (DOF) and special capabilities. However, the same The principles we learn about manipulators also apply to robot rovers, whether kinematics differential motions, dynamics or control. E:\BLOGS\b451b9d1cd9bc8c22d94a77f9ee3fa3f.jpg Robots are very powerful elements in today's industry. They are capable of demonstrating many different tasks and activities are accurate and do not require general security and comfort elements needed by humans. However, this requires a lot of effort and many resources for the robot to function properly. Most companies made robots in the mid-1980s with only a few exceptions, there are only companies that make real industrial robots remained in the market (Adept, Staubli, Fanuc, Cuca, Epson, Motoman, Denso, Specialized robotic companies such as Fuji, and IS robotics, as well as Mako Surgical Corporation). Early entrepreneur predictions about the number of robots in the industry has never materialized because high expectations cannot be met current robots, as a result, have many thousands of robots in the industry working tirelessly and satisfactorily for the intended jobs, the robots are not overwhelmed in place of workers. They are used wherever they are useful. Like humans, robots can do Some things, but not others. They are designed correctly for the Intended purposes, they are very useful and to be used. The subject of robotics has many different areas. Robots are never alone useful. These can be used in conjunction with other devices, peripherals and other manufacturers Machines. They are usually integrated into one system, which is designed as a whole do a thing or do an operation. What is a robot? If you combine a traditional robot manipulator with a crane, say, utility or you will notice that the towing vehicle is similar to the robot manipulator crane. Both have several links that are regularly attached to each other with joints, where each joint is moved by some kind of actuator. In both systems, the "hand" of the manipulator can be moved into space and placed in the desired workspace of the system. Each it can carry a certain load and is controlled by a central controller. However, one is called a robot and one is called a manipulator (or, in this case, a Crane). Similarly, material handling manipulators that move heavy objects in manufacturing plants look like robots, but they are not robots. The fundamental difference between both, the crane and the manipulator are controlled by a man and controls the actuators, while the robot manipulator is controlled by a running computer program. This difference between the two determines whether or not a device is simple manipulator or robot.
CLASSIFICATION AND ADVANTAGES/DISADVANTAGES OF ROBOTS Classification of Robots: The following is the classification of robots according to the Japanese Industrial Robot Association (JIRA): Class 1: Manual handling device: A device with multiple degrees of freedom, actuate by the operator. Class 2: Fixed Sequence Robot: A device that performs the next steps of a task according to a predetermined, immutable method, it is difficult to modify. Class 3: Variable Sequence Robot: Same as in Class 2, but easy to modify. Class 4: Playback Robot: The human operator performs the task manually by running the robot, which then records the moves for playback; The robot repeats the same movements as recorded. Class 5: Numerical Control Robot: The operator supplies the robot with a vibration program without manually teaching the work. Class 6: Intelligent Robot: Robot to understand its environment and ability to successfully complete a task despite changes in the environment. The Robotics Institute of America (RIA) only considers class 3-6 as Robots. The Association Francaise de Robotic (AFR) has the following classification: Type A: Maintaining equipment with manual control for telerobotics. Type B: Automatic handling equipment with predetermined wheels. Type C: Programmable, servo-controlled robots with continuous or point-to-point Channels. Type D: Same as C but with the ability to retrieve information from its environment. Advantages of Robots: · Robotics and automation are, in many cases, increase productivity, security, products, quality and sustainability of products. · Robots can operate in hazardous environments such as radiation, darkness, heat and cold marine support, space and so on without the need for life support, comfort or concern for security. · Robots do not need an environment like lighting, air conditioning, ventilation and noise protection. · Robots work constantly without fatigue or fatigue or boredom. They don't get it there is no madness, no hangovers and no medical insurance or leave. · Robots have repeatable accuracy at all times, unless something happens unless they are worn. · Robots are far more accurate than humans. Some of the simplest linear accuracy one thousandth of an inch. The new layer-handling robots have micro-inch precision. · Robots and their tools and sensors have capabilities beyond humans · Robots can process multiple stimuli or tasks at once. Only humans can process it an active stimulus. · Workers robots replace human labour, causing economic hardship and worker dissatisfaction and resentment, and the need to regain a replacement workforce. Disadvantages of Robots: Robots are not capable of responding to emergencies unless the situation is included in the response system. They need security measures to do so operators and other machines working with them should not be injured. These include · Inappropriate or incorrect responses. · Lack of decision-making power. · Loss of energy. · Damage to the robot and other equipment. · Injuries to humans. Robots, although superior in some senses, have limited capabilities: · Knowledge, creativity, decision making and awareness. · Degrees of freedom and ability. · Sensors and vision systems. · Real-time response. Robots are expensive because of: · Initial cost of equipment and installation. · Peripherals required. · Training is required. · Programming required.

Micro-needles are used to deliver the drug through transdermally. They vary in size 20-1500 micron in length and diameter not more than 30 micron. These serve the purpose of both conventional hypodermic needles and transdermal patches. Types of micro-needles Solid Coated Dissolving Hollow How micro-needles deliver drugs ● Poke and patch: in this method micro-needles are inserted into the skin and the drug remains on the skin in the form of patch. ● Poke and coat : drug is coated on micro-needles and inserted into skin. ● Biodegradable (poke and release) : biodegradable micro-needles are released into skin. ● Hollow (poke and flow): drug is injected through hollow needles. You can follow this link to check how drugs are delivered through micro- needles. https://www.youtube.com/watch?v=cNwVvcXLiWc Advantages ❖ painless ❖ Self administration is possible ❖ No Microbial growth ❖ Biodegradable ❖ Less costly Disadvantages v Proper care needed v Chances of breakage of needles v Inflammation on site of application v Skin irritation Conclusion Although micro-needles for cosmetic products are available in the market, a lot of research is going on for micro-needles as a future drug delivery system instead of hypodermic needles which is painful and these will also provide sustained release of the drug.
