Farmageddon: The True Cost of Cheap Meat

Cost of Cheap Decoupled

It is known that requiring a controlled system to be decoupled may increase costs in terms of some performance measures. However, decoupling may be desirable from an applied perspective. This paper gives an explicit quantiication of the costs of decoupling. In particular, the average quadratic tracking error is used to quantify performance. The analysis exploits the parametrisation of all decou...

True Random Number Generation for Cryptography, on the Cheap

This paper describes an open system for building a True Random Number Generator and using it for cryptographic purposes. The main components of this system are an Arduino Uno and OpenSSL. Introduction: Random number generation is an important part of cryptography, because flaws in random number generation can be used by attackers to compromise encryption systems that are algorithmically secure....

The True Cost of Mobility?

and games, even our extensive music collections. We’re wired together and can keep tabs on each other at almost every moment of the day. In this issue, we feature several articles that focus on the technical breakthroughs that have allowed this revolution to happen and that are enabling even more sophisticated behaviors. But it would be remiss to focus on this topic without discussing privacy, ...
