The 3rd Generation Partnership Project (3GPP) is ready to present a new cellular network standard; Long Term Evolution (LTE). LTE improves communication for public safety users like police, medical, and rescue workers in cellular networks. This creates a need to examine whether LTE can satisfy public safety users requirements. This thesis has a focus on group communication with a voice service....

of which was the fact that throughout the operations on the Western Front there was no epidemic of any water-borne diseases. Bearing in mind that in a large number of instances the ordinary sources of supply were either rendered useless or totally destroyed, and that to make up the deficiency drinking water for the armies had to be taken haphazard from streams, canals and rivers, the entire suc...

We thank Black (2008) for his thoughtful assembly of diverse perspectives including ours on why another disastrous Mississippi River flood occurred so soon after 1993. We have an update that elucidates and quantifies several key points of his article, particularly that a) flood frequency and heights are increasing, b) water levels for regulatory “100-year” floods are profoundly underestimated, ...

The building of public safety network (PSN) infrastructures for the purposes of facilitating communication, sharing of information, and collaboration among first responders has been identified as a key policy goal in the aftermath of events such as the September 11th terrorist attacks and Hurricane Katrina. Early analysis of professional and academic literature in conjunction with prior empiric...

First responders for Public Safety (PS) require seamless roaming, high data rates, and immediate access to voice, video and data applications. The Public Safety Communications Research (PSCR) macro-network is often unable to provide these services satisfactorily within buildings. Currently, the PSCR is in the process of developing standards for the PS LTE signal communication. To that end, they...

To date, little has been written about the implementation of utilizing food safety informatics as a technological tool to protect consumers, in real-time, against foodborne illnesses. Food safety outbreaks have become a major public health problem, causing an estimated 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths in the U.S. each year. Yet, government inspectors/regulators t...

BACKGROUND As a public safety regulator, the Technical Standards and Safety Authority (TSSA) of Ontario, Canada predicts and measures the burden of injuries and fatalities as its primary means of characterizing the state of public safety and for decision-making purposes through the use of a simulation model. The paper proposes a simulation-based predictive model and the use of disability-adjust...

An increasing number of people move to cities in search of better opportunities for themselves and their families. This movement makes it difficult for the local government to understand citizens’ needs fully, particularly pertaining to public safety matters. Thus, in the city of East London where this issue is prevalent, a smart city project was introduced to help alleviate these concerns. Dur...
