Electric Vehicles

-
 Day by day petrol price hike might have made us at least think about an Electric Vehicle. Most of us are really confused whether to own one or not due to many reasons like higher price, maintenance, lesser range, availability of charging stations etc. It is actually a technological wonder. Let us now see what are the advantages, challenges as well as disadvantages of owning an EV. EVs came into existence in mid-19th century. Electricity was only one among the preferred method of vehicle propulsion. Later, modern IC Engines dominated the sector. In 21st Century, highly efficient EVs which were capable of replacing IC engines were produced. The main advantage was its emission-less engines. Increased focus in renewable energy and to reduce climatic changes caused due to carbon emission was the main agenda for the EV developers. Nowadays, electric engines are capable enough to produce an equivalent power which an IC Engine can generate. Premium automotive brands like Mercedes, BMW, Po...

MOBILE TECHNOLOGY

-

 


Mobile technology is a category consisting of a wide range of devices, with new two-way technology being created each day with unique uses. Regardless of form factor, all of these are linked by their capability to send and receive signals by communicating with other devices on networks


WHAT IS MOBILE TECHNOLOGY?

Mobile technology is technology that goes where the user goes. It consists of portable two-way communications devices, computing devices and the networking technology that connects them.

Currently, mobile technology is typified by internet-enabled devices like smartphones, tablets and watches. These are the latest in a progression that includes two-way pagers, notebook computers, mobile telephones (flip phones), GPS-navigation devices and more.

The communications networks that connect these devices are loosely termed wireless technologies. They enable mobile devices to share voice, data and applications (mobile apps).

Mobile technology is pervasive and growing. The number of smartphone users has climbed beyond 3 billion and the global mobile workforce is expected to reach 1.87 billion by 2022


MOBILE DEVICE EXAMPLE

Mobile devices are everywhere and they're not just limited to the phones in our pockets. Whether it's distributing a stronger WIFI signal or enabling a user to access phone calls from their wrist, mobile devices come in all shapes, sizes, and functionalities. Some of the most popular forms of mobile technology include:

 Smartphones  most people have access to a smartphone today but any cell phone can be considered mobile technology.

Laptops  An evolution from the notebook computers of the past, modern laptops come in a variety of sizes but nearly all contain two-way network connectivity capabilities and can be used in a variety of environments.

Tablets  Often operating on the same systems as smartphones but with more powerful components, tablets offer even more portability than laptops with much of the same functionality.

Smart watches  These devices are designed to sync with other devices, like smartphones or laptops, and utilize cloud capabilities to display notifications and applications on a smaller, wearable screen.

Hotspots  Devices require an internet connection of some kind to access the internet and hotspots provide a solution when a connection would be otherwise unattainable. Often running via cellular networks, hotspots host private WIFI networks that users can connect to in unorthodox environments.

Mobile gaming consoles  Gaming consoles have long existed in portable forms but recent generations possess the power to rival home consoles and feature two-way connectivity for accessing downloadable content, playing games with others over a network, and sending messages.

IOT Devices  Many, but not all, IOT devices can be considered mobile technology, such as sensors and smart watches. These devices represent a broad category and react to their environment to communicate specific signals when an event is triggered.



 MOBILE NETWORKS


A cellular network or mobile network is a communication network where the link to and from end nodes is wireless. The network is distributed over land areas called "cells", each served by at least one fixed-location transceiver (typically three cell sites or base transceiver stations). These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell. 

When joined together, these cells provide radio coverage over a wide geographic area. This enables numerous portable transceivers(e.g., mobile phones, tablets and laptops equipped with mobile broadband modems, pagers  etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations, even if some of the transceivers are moving through more than one cell during transmission.

THE NEURAL NETWORKS IN CONTROL SYSTEMS

-
 The ever-increasing technological demands of our modem society require innovative approaches to highly demanding control problems. Artificial neural networks with their massive parallelism and learning capabilities offer the promise of better solutions, at least to some problem.  Neural networks have the potential for very complicated behavior. They consist of many interconnected simple nonlinear systems, which are typically modeled by sigmoid functions. The massive interconnections of the rather simple neurons. which make up the human brain, provided the original motivation for the neural network models. The terms artijicial neural networks and connectionist models are typically used to distinguish them from the biological networks of neurons of living organisms.  Neural networks are characterized by their network topology-that is, by the number of interconnections, the node characteristics that are classified by the type of nonlinear elements used, and the kind of lear...

Laughing Jack - Explained

-
 Welcome to The Infographic’s HorrorpieceTheater! Today we’re taking a look at another ofthe internet’s most famous urban legends- Laughing Jack, the Demonic Killer- and exploringhis origins to discover, was this hideous monster real? Could he be out there right now, probablybehind you or under your bed this very second, waiting to claim his next victim? Stay tuned and find out! It was Christmas Eve in the late 1800s.  In a small wooden home in the poor outskirtsof London, Isaac, a seven year old boy, looks wistfully out the window into the dark night. He can still see families celebrating togetherthrough the grimy windows of the apartments and homes around him, joyfully singing asthey wait together in anticipation for the Christmas morning to come.  In young Isaac's home though, there is nosinging, no warmth, and no celebrating. There is only the silence that normally pervades,silence that is only occasionally broken by his mother's shrill voice calling for himto come an...

What is Grafting - Methods,Techniques,Benefits of Grafting | Grafting Tools

-
Grafting also is known as graftage, is a horticultural technique whereby tissues of plants are joined together so that they continue their growth together. The upper part of the combined plant is called the scion while the lower part is called the rootstock. The grafting technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agriculturalBusiness. In most cases, one plant is selected for its roots and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion or cion.[1] The scion contains the desired genes to be duplicated in future production Before going in detail about Grafting techniques and advantages, Let me explain a few scenarios: 1. Have you ever come across one of those 'miracle' trees? Like - an apple tree that produces six different kinds of apples, or a tree that grows plums, peaches and other fruits, all on the same team. Talking about a...
