For years, manufacturing and engineering companies have been using digital models of products and systems for enhanced design, simulations, and maintenance. Unlike computer simulations, they incorporate Internet of Things (IoT) data to predict how a real-world system will respond to changes. Medical technologists are now applying the concept to the most complex system of all: the human body.

Few jobs look more ripe for robotization than those of the guide dogs used by blind and sight-impaired people. While the canny canines are great at helping their human owners navigate safely around people and obstacles in streets, buildings, and cities, the animals themselves are in extremely short supply, so few of those who need a guide dog actually get to own one.

Over time, experience—and sometimes hard lessons—have shown that security is more than just technology, processes, or a team of IT specialists. Without a strong corporate culture that prioritizes cybersecurity, even the best efforts can be overlooked or misunderstood. So, how can companies get employees involved in improving security? The question raised above is on the minds of almost every CISO. Based on industry experience, here are the key conclusions most often reached:First, raise awareness.

You expect food, utilities, healthcare, and essential products and services to be readily available. Even a short lapse in any of these creates panic as your standard of living takes a hit. Yet we are experiencing these lapses in increasing frequency and severity, not due to the weather, mechanical failures, scarcity of resources, or a lack of hospitals, treatments, or healthcare professionals.

We claim two things about our profession. Computer science studies information processes, natural and artificial. Computer science is a master of abstraction. To reconcile the two, we say that abstraction is the key that unlocks the complexity of designing and managing information processes. Where did we get the idea that our field is a master of abstractions? This idea is cosmic background radiation left over from the beginning bangs of our field.

The integration of generative artificial intelligence (GenAI) tools into higher education has sparked considerable discussion. An analysis of survey responses from 843 science and engineering undergraduate students across four academic years reveals several patterns of how students use GenAI tools throughout their academic journey. In this post, we present and discuss these patterns.

Many important practical computations, such as scheduling, combinatorial, and optimization problems, use techniques known as integer programming to find the best combination of many variables. In these problems, some or all of the variables are restricted to integer values, which requires exponentially greater resources to solve than if the variables could take any value.

Okay, PCs in the title could be Political Correctness or Personal Computers or even Peace Corps. But it is not. It stands for Program Committees. As researchers, in academia or industry, we often are asked to serve on Program Committees of conferences in our fields of expertise. Serving on PCs signals one is a good citizen of our global technical village and has its own altruistic rewards.
