What is Blockchain?

 The well liked definition of blockchain is "a time-stamped system in which a record of immutable transactions made in bitcoin or another cryptocurrency are maintained across clusters of computers that are linked in a peer-to-peer network. ” One and all “block” of data are secured and bound to each other using cryptographic principles that form a “chain.” A blockchain network has no central authority because it is technically a shared ledger. The information contained in a blockchain network can be seen by anyone, which means it is completely transparent. Subsequently, each one involved in the network is accountable for his or her actions.

Using blockchain, one can pass information very safely, simply and in an automated way from point A to point B.  On one end, a transaction is initiated by the party creating a block. The block is then verified by thousands, or even millions, of computers spread across the internet. After verification, the block is added to a chain that is kept over the network, creating a distinct record with a unique history which is decentralized and distributed. Hereafter, it wouldn't be possible for hackers to falsify a single record as they would need to access and take over the data on all linked computers at precisely the same time.

The blockchain maximizes accessibility, security and accountability. It not only allows the user to transfer and store money, it can also replace all processes and business models that rely on charging a fee because blockchain transactions are free.

Web applications

What is a web application?

What is a web application?

A web application is a type of application software that can run in a web browser. Web apps aren't the same as mobile apps but they look and behave the same when accessed in a browser on a mobile device.  They can be built for all platforms as long as they can run in a web browser as they are not platform specific.

Since web apps are not supposed  to be written in a specific coding language. Instead, common coding languages can be used over multiple platforms — like a combination of server-side script, like PHP, and client-side script, like HTML and JavaScript. This makes them not only easy to build but also to maintain. 

Taking into consideration the future and scope of their design and development, it grows considerably. The presence of a website is essential for the owners of small as well as large enterprises. Web apps help businesses to communicate with their customers. They can stand alone and also become a part of a larger website. For instance, a contact form, where a user enters information to sign up for a business’ mailing list. There are many great examples of successful web apps available Google Docs , Netflix , Gmail , Microsoft Office and so on.


What's the Future of Drone Technology in Logistics and Supply Chain?

A lot of investment in research and development of drones for logistics has been done by global brands. Companies like Google, Amazon, DHL, and Walmart are diligently experimenting with autonomous systems and robotics. On the other hand, 3PL firms are using drones to obey their Service Level Agreements they have in place with their clients. In the past years, significant advancements of drone hardware have been noticed, paving the way for an intelligent automation software that makes drones cost-effective for logistics and supply chain uses. 

In the end, it's obvious that in the future drones will transform the supply chain process seriously, given the strong interest and investments in the technology. Drone-based deliveries, however, can only be scaled if logistics firms can work effectively with the government, regulators, and customers to overcome barriers.

Advantages of using drones in logistics

  • Workforce requirements and equipment can be reduced.
  • In the cases of shortage or high weakening, it can act as a substitute for basic tasks of employees.
  • Operational and shipping cost for drone-based last-mile deliveries is reduced.
  • Multi-party collaboration and their clients since drone solutions are easily scalable and highly customisable. 
  • Unification with the warehouse management system is ideal with most drone solutions..

Ways drones can be used for logistics, operations, and distribution

They can be exploited for transportation or delivery of orders to customers. This is especially true for last-mile deliveries in urban areas with heavy traffic congestion. As of April 2020, the FAA in the U.S. has yet to authorize any large scale operations. Deliveries of medicines and relief packs to remote and rural areas are already being tested. Remotely-operated drones can be used in inspecting infrastructure after a disaster for risk evaluation purposes.

  • Security surveillance of large areas for logistics such as warehouses and factories
  • Maintenance assessment of infrastructure integrity of yards, terminals, and warehouse roofs
  • Scanning of pallets inside distribution centers, allowing the operations team to view inventory stored on the premises as well as searching for misplaced goods in difficult-to-reach spaces
  • Collection of video and images during inventory audits

Artificial Intelligence

What is Artificial intelligence?

Artificial intelligence (AI) refers to the theory and development of a machine’s ability to perform tasks that ordinarily need human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. A machine can be said to be artificially intelligent; it performs tasks or behaves like humans. Some tasks that can be performed by an AI-driven machine are: Visual perceptions ,Speech recognition , Language translation. There are various useful technologies such as self-improving algorithms, machine learning, big data, pattern recognition which are included in AI. Soon, each industry or sector would be touched by this powerful tool in India.

The scope of Artificial Intelligence learning makes it  possible to utilize AI run rating machines that can evaluate unbiased solutions. This is something that is moderately being taught in institutes. Other applications of AI include real-time text to speech as well as text translation systems. 

It can help determine proper crops to grow in a desirable environment on a fertile area and also the sowing technique to improve performance as well as minimise expenses. The study of useful parasites for advanced preparation of insect control can also be done and their behaviour can be forecasted. Predicting modelling using AI can be important in providing more precise demand-supply details.

Many organisations deal with a significant amount of data. For instance, in the Banking sector or government organisations which are having a huge database of people's personal data, there is always a risk of stealing, and hence a security mechanism needs to be put in place. An apt example of this field is Cognitive Artificial Intelligence. Hazards can be detected as well as analysed, while understandings can be given to the analysts for making better-informed decisions. The AI is obtaining much more elasticity by making use of Machine Learning formulas and also Deep Learning networks.

AI plays a vital role to find smart solutions to these modern-day problems. Strong knowledge of data structures and data modelling is required. To pursue an Artificial Intelligence online course, one should know subjects such as Mathematics, engineering, physics, Programming expertise in one of the programming languages like Python, Java, C++, R, Working Knowledge of Data Science algorithms and libraries. The various job profiles in the field of AI include Machine Learning Engineer, Data scientist, Business Intelligence Developer.

Medical Technologies

Technology is a lot more general than people think. Like, a computer is an example of technology. Technology is just the application of knowledge for a practical purpose, either in the home, in industry, or somewhere else.

Though technology is used everywhere, it is a matter of life and death in the medical professions. Millions of lives have been saved with the help of technology. In medical technology, objects are built to protect living organisms from disease or death. 

Benefits Of Medical Technology

Technological developments in the field of healthcare has saved numerous lives and the quality of life is immensely improved. Some of its benefits in healthcare sector are:

Digitalization of Medical Records

Electronic Health Records has replaced traditional and outdated paper-based health records. This helps patients as well as to medical coders to get access to health records at just a click of a button. EHR is easy to access from any nearby medical facility. This contributes to greater patient care. Distant patients can also be assessed by the doctors easily.

Better Public Health

EHRs offer indispensable information to those who perform clinical research. This help them in putting together treatments for common types of health issues. A systematize healthcare IT system is beneficial in providing valuable awareness about the spread of a health issue, and  allow quick and effective execution of preventative measures.

Eases execution of task

The life of medical coders and billers have simplified to a great extent by the advancement in electronic medical records. Inputting data into electronic system takes lesser time than standard paper-based methods. It also lowers the chances of errors in recording patient personal information, financial details and medical data. Digital access of patient records enables medical coders to work from their home. The productivity and efficiency of a system is increased.

Lower Healthcare Costs

The total charges of outpatient care has been reduced to 3% by the transition from paper-based records to electronic medical records.

Cloud storage

Storing extensive medical data on the cloud makes it easier to access as well as process. This storage space requires less investment and is safer and secure than storing paper-based medical records that have a possibility of getting stolen, misplaced or damage. The data stored on Cloud can be accessed by professionals and  healthcare patients anywhere across the world.

Wearable Technologies

Wearable technology is any sort of device designed to be worn on the user's body. Such devices can take many various forms, including jewelry, accessories, medical devices, and clothing or elements of clothing. The term wearable computing implies processing or communications capabilities, but truly, the sophistication among wearables can vary.

The most sophisticated samples of wearable technology include computer science (AI) hearing aids and a holographic computer within the variety of a video game (VR) headset. An example of a less complex style of wearable technology may be a disposable transdermal patch with sensors that transmit patient data wirelessly to an impression device in an exceedingly building i.e healthcare facility.

Modern wearable technology falls under a broad spectrum of usability, including smartwatches, fitness trackers like the Fitbit Charge, VR headsets, smart jewelry, web-enabled glasses and Bluetooth headsets. Wearables work differently, supporting the category they belong to, like health, fitness or entertainment. Predominantly, wearable technology functions by incorporating microprocessors, batteries and connectivity to the web that the collected data may be synced with other electronics, like mobile devices or laptops.

Wearables are embedded with built-in sensors that keep track of bodily movements, provide biometric authentication or assist with location tracking. For instance, activity trackers or smartwatches -- the foremost common forms of wearables -- include a strap that wraps round the user's wrist to observe their physical activities or vitals throughout the day.

While most wearables are either worn on the body or are attached to clothing, some function without even physical contact with the user. Other wearables use remote smart sensors and accelerometers to trace movements and speed, and a few use optical sensors for measuring pulse or glucose levels. A standard factor among these technology wearables is the fact that all of them monitor data in real time.
