Enriching your network via diversity
By Inbal Talgam-Cohen
Magazine: Spring 2014 | Volume 20, No. 3
Computing in the new century is no longer confined to the desk, behind a monitor. It is wireless, ubiquitous, and on the go. It has taken to the skies, the oceans, and the land all around us. These cyber-physical systems are co-habitants of a complex and advanced ecology we have built for ourselves. Cyber-physical systems are electro-mechanical systems, which harness the power of computation, communication, control, and coordination to accomplish their assigned task(s) efficiently.
In this issue, we present the concept, applications, challenges, and progress of ubiquitous computing; the technologies that make computing infiltrate into every aspect of our daily lives; and the machines and systems that reshape the air, water, and land on earth.

Feeding a hungry world
The fusion of next generation sensors and advanced information systems, combined with advances in unmanned aircraft systems that have emerged through aerospace engineering technologies, will contribute to the challenge of feeding our future world in a sustainable manner. Without these advances, the world may find itself short of food and perhaps on the brink of global conflict.

Connecting with oceans using underwater acoustic networks
Oceans cover a majority of our planet and are currently lacking in regards to exploration and technological innovations. One technology that can help enable more aquatic applications is underwater acoustic networks (UANs). This article discusses the current status of UANs, the new applications that can be provided, and the challenges faced by this technology.

A dexterous crabster robot explores the seafloor
Crabster CR200 is a giant crab robot with six legs and 30 powerful joints developed at the Korea Research Institute of Ships and Ocean Engineering. The robot can help explore ancient shipwrecks in areas of harsh tidal currents and turbid water, where traditional underwater vehicles have trouble operating.
