Laryngealizations are irregular voiced portions of speech, which can have morphosyntactic functions and can disturb the automatic computation of F0. Two methods for the automatic detection of laryngealizations are described in this paper: With a Gaussian classifier using spectral and cepstral features a recognition rate of 80% (false alarm rate of 8%) could be achieved. As an alternative a “non...

Developmening systems applying machine learning and data mining techniques is one of the approaches to combating network intrusion.Many IDS Intrusion Detection Systems)suffer from a high rate of false alarms and missed intrusions.Tha challenge is to be able to improve the intrusion detection rate at a reduced false positive rate. To counter imbalance in data, a combination of oversampling (synt...

The use of continuous glucose monitoring systems (CGMSs) with lowglucose alarms is advocated as a means to decrease the risk of hypoglycemia in type 1 diabetes. Unfortunately, marked mismatches between CGMS readings and actual blood glucose (BG) concentrations limit the usefulness of CGMS in preventing hypoglycemia (1). Although we showed recently that raising the alarm level to compensate for ...

This paper focuses on how the behavior of drivers in response to warning systems is influenced by their trust in those warning systems. The experimental examinations show that a) false alarms result in a reduction in trust and an increased reaction time to braking, b) a lack of alarms result in a delay in the recognition of hazardous situations, c) excessive trust induces significant delays in ...

BACKGROUND Falls are a serious health problem in old adults especially in nursing home residents and hospitalized patients. To prevent elderly from falling, sensors have been increasingly used in intramural care settings. However, there is no clear overview of the current used technologies and their results in fall prevention. OBJECTIVES The present study reviews sensor systems that prevent f...

BACKGROUND Disposable electrocardiographic lead wires (ECG-LWs) may not be as durable as reusable ones. OBJECTIVE To examine differences in alarm events between disposable and reusable ECG-LWs. METHOD Two cardiac telemetry units were randomized to reusable ECG-LWs, and 2 units alternated between disposable and reusable ECG-LWs for 4 months. A remote monitoring team, blinded to ECG-LW type, ...

Two experiments tested the influences of vivid imagery and person schemata on eyewitness accuracy. Participants watched an event sequence including actors performing stereotype-consistent and inconsistent actions. Additionally, participants either read descriptions of actions (Experiment 1) or vividly imagined actions (Experiment 2). After either 30 minutes or 2 days, recognition memory, source...
