The increasing complexity of today's information technology (IT) together with our dependency upon it, has led to a situation in which a security breach not only has effects for individuals but can also affect the availability of critical services (power supply, communication) or result in significant financial loss. Criminals and terrorists want to exploit(More)
Digital investigation methods are becoming more and more important due to the proliferation of digital crimes and crimes involving digital evidence. Network forensics is a research area that gathers evidence by collecting and analysing network traffic data logs. This analysis can be a difficult process, especially because of the high variability of these(More)
The Bioharness™ device is designed for monitoring physiological variables in free-living situations but has only been proven to be reliable and valid in a laboratory environment. Therefore, this study aimed to determine the reliability and validity of the Bioharness™ using a field based protocol. Twenty healthy males participated. Heart rate (HR), breathing(More)
The Bioharness(™) monitoring system may provide physiological information on human performance but the reliability of this data is fundamental for confidence in the equipment being used. The objective of this study was to assess the reliability of each of the 5 Bioharness(™) variables using a treadmill based protocol. 10 healthy males participated. A(More)
This paper studies the reliability of geometric features for the identification of users based on Hand Biometrics. Our methodology is based on genetic algorithms and mutual information. The aim is to provide a system for user identification rather than a classification. Additionally, a robust hand segmentation method to extract the hand silhouette and a set(More)
Digital crimes are a part of modern life but evidence of these crimes can be captured in network traffic data logs. Analysing these logs is a difficult process, this is especially true as the format that different attacks can take can vary tremendously and may be unknown at the time of the analysis. The main objective of the field of network forensics(More)
[Abstract] Electrotherapy is one form of intervention that has the capacity to influence the processes associated with tissue repair. Some modalities are more effective at achieving this than others, and there are differences in they type of tissue that respond to the different modalities. Numerous electrotherapy modalities have significant clinical(More)
Kin selection is a theory that attempts to explain the apparently altruistic behaviour in nature. It suggests that self-sacriice in order to save kin is understandable through consideration of the probabilities of occurrence of an individual's genes in its close relatives. Thus altruism can be explained without recourse tògroup selection'. However, on(More)
