Hazardous environments at the workplace are a significant contributor to injuries due to accidents as well as chronic diseases. There are many occupational health and safety (OHS) systems, but they are costly or not flexible. This paper presents a low-cost OHS. It consists of various sensors that can be used to monitor whether a safety helmet is being worn, the worker is mobile and safety boots are...
In emergency situations such as fires in homes and offices, it is often the case where members of a response team (eg. firefighters) are not able to locate each other due to fire and smoke. It is desirable to have a system which is able to locate all personnel such that a team leader can monitor their location and to enable the firefighters themselves to know their proximity to other firefighters...
This work describes the development of a mobile incident response system which can be used by public entities such as the police or municipality services to improve the assignment of response teams to reported incidents. It is also shown that the system can be easily integrated to augment current indoor air quality monitoring systems in future buildings. The system is based on the capability of smartphones...
This paper describes the work carried out on the implementation of a wireless sensor network that was created for a data center using the 6LoWPAN communication protocol which monitors power consumption readings at various nodes in the system. A direct current (DC) network controller was designed to distribute DC energy through the system and provide power to a data center load in future buildings...
This work presents DDJ, an algorithmic debugger for Java. The main advantage of DDJ with respect to previous algorithmic debuggers is its scalability. DDJ has a new architecture based on the use of cache memories that allows it to scale both in time and memory. In addition, it includes new techniques that allow the debugger to start the debugging session even before the execution tree has been produced...
