We report multiple Doppler measurements of five nearby FGK main-sequence stars and subgiants obtained during the past 4–6 yr at the Keck Observatory. These stars, namely, HD 183263, HD 117207, HD 188015, HD 45350, and HD 99492, all exhibit coherent variations in their Doppler shifts consistent with a planet in Keplerian motion. The five new planets occupy known realms of planetary parameter spa...

The productivity of chemical plants and petroleum refineries depends on the performance of alarm systems. Alarm history collected from distributed control systems (DCS) provides useful information about past plant alarm system performance. However, the discovery of patterns and relationships from such data can be very difficult and costly. Due to various factors such as a high volume of alarm d...

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...

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...
