Resistor 1 Ohms (Ω) Ohms (Ω) Resistor 2 Ohms (Ω) Ohms (Ω) Add Results Equivalent Resistance Resistance is defined as the measure of opposition to charge flow (current flow) in an electrical circuit. It is measured in ohms and symbolized by (Ω)-a Greek letter omega. Naturally, all materials oppose current flow to some extent, and they are classified as either conductors or insulators. Conductors are materials that have very little resistance to electrons flow, they include aluminum, silver, gold, copper, and many more. Insulators, on the other hand, are materials that present very high resistance to electrons flow; examples are rubber, plastic, wood, and glass. Basically, a resistor is an ohmic device that limits the flow of current in a circuit. Most electrical circuits consist of more than one resistor. The relationship between voltage, resistance, and current in an electrical circuit with resistors is given by Ohm’s Law. Ohm’s law is expressed as: I = V/R , where I is the circuit...
In recent years, machine learning has found applications in new and often unexpected areas. With the novel coronavirus outbreak in 2019 and 2020, it makes sense that many have tried to apply machine learning and artificial intelligence to various problems relating to the disease. From modeling the spread of the disease to searching for possible drugs and vaccines, machine learning has been integral to understanding many of the problems caused by the COVID-19 pandemic. Case Study – Disease Dynamics A simple internet search will lead you to hundreds of dashboards showing the current number of coronavirus cases around the world. This stems from how easy it is to access data relating to the virus, especially from reputable sources like Kaggle or Johns Hopkins . This data, along with sophisticated models for disease dynamics has, for example, enabled predictive modeling for the number of people who actually have the virus and the risk of hosting an event in any county in the US . Some...
The world’s first software program to be denied inventor credit on a patent has a winding past, and immense goals set before it. Stephen Thaler is hoping DABUS can make him immortal. We have all contemplated at least once what it might mean to control someone’s mind. Steven Thaler, however, has been experimenting with the idea for the last 30-plus years. His keystone project over that time has been in pursuit of an advanced AI that can reason and create autonomously. A polymath of the highest order, Thaler’s AI has trained hard to excel at stock picking, product design, and even creating art. To achieve these outcomes, Thaler relied on a discovery made early on in his work with neural networks: seeded with mental instability and pushed to the edge of death-inducing madness. These applications produced some of their best creative association right before locking up and ‘dying.’ As Thaler shifted focus from corporate work to independent consulting and his own company, he had a rich well...
The terms artificial intelligence (AI) and machining learning are used interchangeably by many, and sometimes even tech professionals and enthusiasts find it hard to draw a line between the two. There is a good reason for this; Machine Learning is a subset of AI, specifically a derivative branch of study that deals with large sets of data. Machine learning is a specialized branch of AI. If you have read about AI and machine learning in the news you may have come across the phrase, “all machine learning is AI but not all AI s machine learning.” AI is defined as a broad aspect of computer science and engineering that aims at ultimately enabling computers to do things in a similar way as a human and even surpass them. AI is, therefore, acquisition of knowledge and using it intelligently. The main component of AI is artificial neural networks which are modeled to work similarly to a human brain. On the other hand, machine learning is a more specific field about teaching machines how to...
2018 was an exciting year in the realm of technological advancements, surpassing even the most expertly stated expectations. In October 2017, international business consulting firm Gartner published their predictions for the top strategic technology trends in 2018. A year later, in October 2018, Forbes Technology Council convened a panel of experts to offer their take on the most disruptive technology breakthroughs of 2018. A comparison of Gartner’s forecast to the Council’s retrospective provides clues for what may be in store in 2019. If trends hold, it could be an even more explosive year. Gartner is a research and advisory company that operates in 100 countries and serves 15,000 client organizations across the globe. Based on their interactions with these clients, Gartner generated the insights which informed their Top 10 Strategic Technology Trends for 2018 , a report they released in October of 2017. Making sense of a surging technological landscape that continues to bloom so...
While the topic of climate change is controversial in this day and age, it is generally accepted that mass production efforts can do more to clean and maintain the lands and oceans of our planet. As catastrophes like wildfire, famine, and powerful storms drive discussion and incite passion in the world’s population, great minds are finding ways to utilize the latest technologies in hopes of creating positive outcomes for the environment. One such technology making the leap from idea to action is blockchain. A concept first applied to the cryptocurrency Bitcoin, blockchain is a “distributed ledger technology” that is designed to make transactional data transparent, decentralized, and verifiable. Applied to projects focused on helping to sustain the environment, blockchain could allow for the creation of currency systems based upon trackable data, like carbon emissions from mass production. Trading in these currency systems, producers and consumers would be incentivized to make wiser...
Manufacturers have traditionally been at the forefront of technological developments, adopting new practices and technologies to cut down production times, costs, and waste since the early 1900’s. Recent developments in AI, machine learning, connection to the IoT, and blockchain, are already being incorporated into manufacturing businesses. Smart manufacturing is becoming more and more common as it grows through the adoption of sensors throughout production lines and the increased connectivity of machines and systems; it could be said that manufacturing is entering a new golden era of automation. Below is an examination of some of the technology that is changing manufacturing and an examination of how linking these improvements in technology together can further advance the automation of business practices. Many larger manufacturers have been developing AI (Artificial Intelligence) systems that aid robot learning, monitor all parts of the manufacturing process to detect inefficiencies...
We’ve all seen the movies; the year is 2050 and sophisticated robots have gained a mind of their own, taking over the world in a blaze of fire and panic. Whilst the prospect of artificial intelligence is a scary thought in the minds of those who aren’t well versed in current technological trends, the reality is a little less dramatic. However, this is not to say that it’s dull. In fact, AI is perhaps one of the most exciting movements of the 21st century and we’re only just getting started. Artificial Intelligence Well, in simple terms, AI is the ability of a machine or computer program to learn, specifically machines that are able to “think” and act like humans in an intelligent and measured way. With this definition in mind, it is understandable that AI is often still placed in the 21st-century bracket of futurism. However, upon closer inspection, the technology has already been established and is embedded into computerized systems of all kinds. AI is beginning to manifest itself in...
Artificial intelligence (AI) is generating exciting headlines lately. With stories covering seemingly infinite capabilities, from creating expensive art, to keeping the United States of America ahead in the international race to develop cutting-edge weaponry, to helping our homes take care of us, AI can be perceived as having suddenly embedded itself in virtually every aspect of our modern lives. While it is true that AI is a powerful technology with a broad range of business applications, AI is also a young technology still in the earliest stages of development. Due to its potential to achieve intelligence beyond that of humans, it warrants a thoughtful approach to remain beneficial and safe. Image: Digital Wellbeing AI can seem like a nebulous concept to the average person, and separating fact from fiction can be a challenge. The Future of Life Institute (FLI) , a multidisciplinary group of individuals whose mission is “to catalyze and support research and initiatives for...
There is a much-hyped debate between two of the world’s most notable tech entrepreneurs, centered on the risks inherent in the rapid development of Artificial Intelligence (AI). This highly publicized row involves the dueling perspectives of Mark Zuckerberg, Founder and Chief Executive Officer of Facebook, and Elon Musk, most notably co-founder and Chief Executive Officer at Tesla and Space Exploration Technologies (also known as SpaceX). Mr. Zuckerberg is optimistic and eager to advance AI as Facebook chases its goal of building a global community, while Mr. Musk is concerned and cautionary about AI’s potential threats to humanity if its growth is unchecked, its power too centralized. Their arguments are compelling and important to understand, as is the nature of AI technology itself. Though the term “AI” is universally known, it is not widely understood by the general public. This could be because AI technology is in its infancy, and much of what the average person knows about AI...
In the midst of the Fourth Industrial Revolution, known colloquially as Industry 4.0, the World Economic Forum (WEF) has released a report titled The Future of Jobs Report 2018 , which forecasts how global employment will be impacted by emerging technologies. Optimistic in its findings, the WEF expects a net positive for job growth as long as businesses, employees, and governments are proactive and agile in their efforts to align human talent with an evolving job market. Rather than being wholly replaced by robots, humans have an opportunity to merge their talents with available technologies for the purpose of enhancing bottom lines, but it is up to businesses and governments to create an environment conducive to sustainable growth. Based in Switzerland, the World Economic Forum (WEF) was founded in 1971 and is a non-political membership organization comprised of the world’s top public and private companies. The WEF focuses its activities on understanding the strategic challenges of:...
Over recent years, there has been an awful lot of hype over the Internet of Things (IoT). We’re told it will transform our lives, bring about the fourth industrial revolution and possibly even improve our work lives and living standards. Less is said about how this will be achieved, or even what the IoT actually is, and why it will benefit our lives. In an age when technology is moving in leaps and bounds, it is important to stay informed about the changes happening to our world. Here we sift the fact from the fiction in order to understand how business can expect to change as the IoT ushers in a new era for us all. In the most basic terms, the IoT is a network of products, both for commercial and consumer use, which are connected to each other and various services or businesses through the internet. These items have chips with sensors inserted into them which are programmed to record and monitor various functions and use. This information is then communicated within a closed network...
For many, blockchain is synonymous with Bitcoin and other cryptocurrencies. However, although blockchain technology is the basis for cryptocurrencies, it has many more applications than digital currency. Some have stated that blockchain has created the’ internet of value’ while others tout it as the one thing that will change the way we transact with each other forever. While these statements may be true, many people today don’t fully grasp what it is or how it works. Below we shed some light on blockchain technology. Bitcoin Blockchain was invented by a person, or group of people, known as Satoshi Nakamoto , who released Bitcoin, the first cryptocurrency, in 2008 and described it as the first purely peer-to-peer version of electronic cash. Bitcoin is reliant upon blockchain technology which, when broken down to its component parts – distributed files, cryptography, and openness – is nothing new. What is new is the use of these parts in unison. Essentially, blockchain is a computer...
In an increasingly connected world, consumers, businesses, and governments are presented with unprecedented access to data. What they do with that data depends on the questions they wish to ask and the technological capabilities available to produce answers. As the ability to generate insights from data evolves at an increasingly rapid pace, both technology and humans will grow smarter and more empowered. For any study, confidence in the outcomes and conclusions is directly tied to the size and quality of the dataset. Thanks to increasing worldwide digitization and Internet-connectedness, nearly every person on the planet creates mountains of data ripe for study. Entities on the receiving end of these large swaths of data find themselves in possession of a rich, albeit unwieldy, source of market insights. The definition of this “Big Data” evolves as the digital landscape transforms. Think of it not as a thing, but as a concept. In that context, Big Data encompasses all of the...
