Sensor networks that use 802.15.4 in the 2.45 GHz ISM band are prone to radio interference from devices such as microwave ovens, WiFi devices, and Bluetooth devices. Interference can cause packet loss and thus reduces network performance and lifetime. Online detection of interference in sensor networks is challenging, because nodes cannot decode foreign transmissions due to incompatibility betw...

Optical fiber modulators are of great interest to space flight projects for communications and LIDAR applications. Due to the harsh environments and long duration for most missions, space flight applications have a unique set of demands for photonics parts. This study focuses on the reliability of commercially available optical fiber modulators for space flight environments. General failures mo...

This paper describes the first hand experiences of the electronic point of care (ePOC) project team and the project management and research and development issues that emerged over the course of a collaborative 3 year eHealth project. The paper highlights that despite the best of intentions by project managers, researchers and developers, a technologically innovative concept is no guarantee of ...

Software is a fundamental and integral part of many medical devices. While the doctor who performs an operation must be licensed, the developers who create the software used in these devices undergo no such licensing. For this reason it is especially important that designs which can be subjected to rigorous analysis be produced prior to software development. Such designs are fundamental to effe...

An emerging trend in mobile communications is the parallel usage of multiple radio technologies in mobile devices, tablets and other communications modules. In order to support this parallel operation, the devices are equipped with multiple radio transceivers, which are located extremely close to each other. When the different radio technologies operate simultaneously these transceivers interfe...

Legislation and rural communities are increasingly requesting reductions in odor emitted from swine production facilities. If odor is regarded solely as a nuisance, and not an environmental hazard (as in this research), such that the objective of treating ventilation exhaust air is to prevent odor from impacting nearby receptors, it is unnecessary to treat exhaust air when dispersed odor is not...
