Understanding the complex and increasingly data-intensive world around us relies on the construction of robust empirical models, i.e., representations of real, complex systems that enable decision makers to predict behaviors and answer “what-if” questions. Empirical models lie at the heart of much science (e.g., quantitative physics, material science, chemistry, biology/medicine, …

Traditional missiles powered by rocket motors typically carry both fuel and oxidizer. An air-breathing ramjet missile can dispense with the separate oxidizer payload, reducing the size of a propulsion package.  Thanks to ramjets, smaller missiles use that space for other things, like a bigger warhead or more fuel. Ramjets, according to …

A database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques. The database management system (DBMS) is the software that interacts with end users, applications, and the database itself to …

Broadly speaking, cloud computing refers to the practice of remotely storing and accessing information and software programs on demand, instead of storing data on a computer’s hard drive or accessing it through an organization’s intranet. This practice relies on a cloud infrastructure, a collection of hardware and software that may …

New data from SIPRI’s Arms Industry Database shows that arms sales by the world’s 25 largest arms-producing and military services companies (arms companies) totalled US$361 billion in 2019. This represents an 8.5 per cent increase in real terms over the arms sales of the top 25 arms companies in 2018. Among …

Once just an idea in sci-fi pictures such as 2001: A Space Odyssey but now a realistic vision, space tourism could be on the horizon. Programs like Space X plan to put civilians in space by 2026. One of the biggest questions for people who may be intrigued about making …

Silicon Valley is the world’s top tech hub today. With a $128,308 per capita in the annual gross domestic product (GDP-PPP), if Silicon Valley were a country, it would be the second wealthiest in the world behind Qatar. Silicon Valley is home to major tech companies such as Google, Apple, …

As warfighting has progressively become more sophisticated, involving larger forces, encompassing greater areas, and containing many new and more lethal weapon systems, the communication systems supporting the command and control functions have undergone a similar evolution. Communication methods have evolved to the capability of rapidly establishing worldwide “real time” communications …

The work-from-home needs of employees due to COVID-19 could help drive big changes in how laptops and other devices are sold. Digital transformation and the work-from-home movement may not be the only big technology trends gaining strength due to the COVID-19 pandemic of 2020. Also picking up traction in the …
