In this study, we transform the verification scores of a speaker recognition system in order to standardize the imposter score distribution, this facilitates setting of a speaker-independent threshold at desired False Alarm (FA) rates. Impostor score distributions are estimated using GMMs, and a univariate Gaussianization [1] transform (which is a monotonically increasing mapping) is applied on...

In most field environments, unexploded ordnance (UXO) items are found among extensive surface and subsurface clutter and shrapnel from ordnance. Traditional algorithms for UXO remediation experience severe difficulty distinguishing buried targets from anthropic clutter. Furthermore, naturally occurring magnetic geologic noise often adds to the complexity of the discrimination task. These proble...

This paper presents a new feature-selection approach based on the cuttlefish optimization algorithm which is used for intrusion detection systems (IDSs). Because IDSs deal with a large amount of data, one of the crucial tasks of IDSs is to keep the best quality of features that represent the whole data and remove the redundant and irrelevant features. The proposed model uses the cuttlefish algo...

The kidneys are responsible for filtering waste products from the blood. The dialysis is a procedure to replace the renal (kidney) function through Haemodialysis machine in people who suffer from end stage renal disease. Haemodialysis machine provide the fluids of dialysis for the cleaning of the patient’s blood and removal of excess fluid. One aspect to take care in the development of a dialys...

Chattering alarms repeatedly make transitions between alarm and non-alarm states without response from operators, and severely deteriorate the performance of industrial alarm systems. Two rules are formulated based on the metrics of alarm durations and intervals to detect chattering alarms caused by random noise and oscillation. An online method is proposed to reduce the number of the chatterin...
