Wireless sensor networks (WSN’s) have been receiving a lot of interest in the last two decades due to the variety of applications that can benefit from them. As the interest in WSN’s grows, addressing the physical constraints ...

Security and message authentication play a crucial role in communications. The current hashing standards for message authentication are SHA-1 and SHA-2. Attacks on SHA-1 which show potential vulnerabilities of this ...

Brazil is a huge country with vast natural reserves, mainly located in the Amazon region and the South Atlantic. In the last decade its economic growth and increasing importance in the global stage, have motivated Defense ...

Current traditional methods of gathering topographic data for hydraulic modeling can be time consuming and costly. One potential method to gather topographic data in a more timely and costly efficient manner is the use of ...

Organic Light Emitting Diode (OLED) has attracted an incredible interest for display applications due to benefits such as a wide viewing angle, high contrast ratio, vivid color, low power consumption, high response speed ...

The cardiac activity can be investigated based on the RR signal - a series of temporal intervals between consecutive heartbeats. The variation of these intervals - called the heart rate variability (HRV) - enables quantitative ...

Fairness within groups is important to a very broad range of problems, from policies for battery-operated soccer robots to distributed traffic control. While no single action may be fair to everyone, it is possible to ...

Today’s university students are tomorrow’s workforce. Transportation infrastructure that is implemented to relieve congestion will be used by these current students in the future when they are in the peaks of their careers. ...

This work aims to expand the abilities of humanoid robots, by implementing ying capabilities to the robot. Humanoid robots are designed to mimic the kinematics of a human, i.e. two arms, two legs, and a head. With this ...

Sensor arrays can provide estimates of the spatial spectrum associated with propagating waves in a variety of environments, e.g., acoustic waves in the ocean. Vaidyanathan and Pal [IEEE Trans. Sig. Proc., 2010, 2011] ...
