Constant false alarm rate

of various wireless devices and technologies engaging static frequency access and to cope up with this demand, Cognitive Radio is a solution of enormous outlook. This article discusses spectrum scarcity problem in wide band. To solve high sampling rate problems in wide band, compressive sensing is done here.A wide band signal is passed through fading channels and then it is estimated using ℓ1 magic technique. Then receiver-operating characteristic curve of the evaluated signal is estimated.

miss according to the SDT, (Foley, 2010) which can be warning signs for a possible future serious accident and exponential problems. When one cannot see the workers instructions clearly, it is very easy to mistake what they say, thus causing a false alarm. (Foley, 2010) According to the SDT, in this case would be a mistake what you see or hear on the roadside due to the poor lighting conditions (Physical Stimulus) that cause one to perceive something incorrectly. (Foley, 2010) The problem we are

were over 350 alarms per patient, making a grand total of over 59,000 alarms (Sendelbach & Funk, 2013). It is no wonder that health care workers can become easily desensitized to the alarm sound, constantly listening to the repetitive alarms for an entire 12 hour shift. In addition to the constant beeps and buzzes from the alarms, many of the sounds are not “true” alarms. There are many things that can initiate a false alarm. It is said that more than 85% of hospital alarms are false, meaning that

Alarm Fatigue Alarm fatigue is a growing national problem within the health care industry that links medical technology as a serious hazard that poses a significant threat to patient safety within hospitals across the country. Alarm fatigue occurs when nurses encounter an overwhelming amount of alarms thus becoming desensitized to the firing alarms. Alarm desensitization is a multifaceted issue that is related to the number of alarming medical devices, a high false alarm rate, and the lack of

strongly correlates with an improved detection rate. In addition to these cognitive abilities, it is essential for employees to know what items are prohibited and be able to recognize their appearance in an x-ray image (Bolfing et al.) All pre-employment testing should be repeatable, standardized and applicable to the job. In the interest of efficiency, pre-employment screening must focus just as much on the rate of false positives, as on the hit rate. Following are the ROC curves of several hypothetical

Comparative Analysis of Adaptive Threshold Based Spectrum Sensing Techniques in Cognitive Radio Networks Abstract:-In the last two decades, the number of wireless communication users and its applications increasing rapidly. With this rapid growth there exists spectrum scarcity. One of the best solutions to avoid spectrum scarcity is cognitive radio with its dynamic spectrum sensing. Cognitive radio is a promising technology, which is used to sense the unused spectrum in an appropriate manner. Various

that modern technologies pose for the human brain? For instance, technology is evolving in a way where multi-tasking is being encouraged and implemented at high rates despite its destructive capabilities. In Levitins’ article, they describe what is called the Dopamine-Addiction Feedback Loop. Multitasking has shown to leave people with a false sense of accomplishment upon finishing tasks. These feeling are triggered by a dopamine released in your brain. Naturally, due to the positivity this stimulus

combat safety issues is by using different alarm systems to alert staff to issues in patient rooms. The many different alarms can be beneficial but can also cause a phenomenon that is referred to as alarm fatigue. Alarm fatigue is defined as a condition of sensory overload for staff members who are exposed to an excessive number of alarms (Blake, 2014). It is a national problem and the number one medical device technology hazard in 2012. The problem of alarm desensitization is multifaceted and could

Motion sensing is the technique in which a system detects a change in position of an object with respect to its surroundings. This paper gives an overview of motion sensors and its applications, and also points out the problems associated with them. II. Introduction Motion sensing is the process of detecting a change in position of an object with respect to its surroundings, or, change in the surroundings with respect to the object. Motion can be sensed in several ways: i. Infrared sensing using

one of the major research problem in network security. Tradition intrusion detection system contain a number of problems, such as low performance, high false negative rate, low intelligent level. In this research work we compared effectiveness of decision tree method in Intrusion Detection System. We also compare the detection rate, false alarm rate for different types of attack. 1.0 Background Intrusion Detection Systems (IDS) are software or hardware designed to automatically monitor activities
