Passive monitoring of high-intensity focused ultrasound
… of tissues such as tumors. Real-time monitoring of the progression of the field distribution of the HIFU transducer during treatment is important for localizing the intersection of the beam with the tissue. By continuously visualizing the HIFU field in a tissue, better positioning of …

In-home passive monitoring for medical applications
Recent years have witnessed a surge of in-home monitoring and sensing systems. They promise to change healthcare as we know it by continuously monitoring patients at home. Yet, despite all of the interest and effort that has gone into designing these systems, their capabilities are rudimentary and …

Application of data-driven technologies for asthma self-management
… However, patients may regard this level of monitoring as tedious because it involves high levels of active engagement on their part. Machine learning and mobile health (mHealth) have the potential to enable a new form of asthma self-management where tedious daily monitoring is minimised, …

Integration of Unmanned Aerial Systems in Class E Airspace: The Effect on Air Traffic Controller Workload
… problems including workload extremes and passive-monitoring demands. One fundamental requirement for operation in the National Air Space is to preserve the safety of the general public. This paper describes an experimental evaluation of the effect different levels of UAS intent information …

The transition from normal to emergency system states: An examination of variables that generate active learning among operators
A failure by human operators to take an active monitoring role in complex automated systems has resulted in operators who are unable to make a transition from normal scanning behavior to the detection, diagnosis, and correction of system failures during a malfunction. Passive monitoring is common …

Fluorescence laser tracking microrheology for quantitative studies of cytoskeletal mechanotransduction
… cellular viscoelastic properties from the passive monitoring of fluorescent microspheres undergoing Brownian motion inside the tested sample. Further instrument enhancement even broadens the FLTM frequency span up to seven decades by modulating data acquisition speed or complementing FLTM …

Interactive phototherapy : integrating photomedicine into interactive architecture
… that are difficult to diagnose or treat, then passive monitoring and treatment methods must be expanded and improved. Second, if self-tracking devices are to become more accurate in monitoring and informing user health, then more contextual information about user positions and activities with …

Rogue Access Point Detection through Statistical Analysis
… Point (RAP) detection, which employs distributed monitoring devices to monitor on 802.11 link layer activities and a centralized detection module at a gateway router to achieve higher accuracy in detection of rogue devices. This detection approach is scalable, non-intrusive and does not require …

Scalable fault management architecture for dynamic optical networks : an information-theoretic approach
… effort low. Instead of the aforementioned passive monitoring paradigm based on parity checks, we propose a proactive lightpath probing paradigm: optical probing signals are sent along a set of lightpaths in the network, and network state (i.e., failure pattern) is then inferred from testing …

Security Enhanced Communications in Cognitive Networks
… from entering CRNs, we design a systematic passive monitoring framework, emph{SpecMonitor}, based on unsupervised machine learning methods to strategically monitor the network traffic and operations in order to detect abnormal and malicious behaviors. emph{Third}, highly capable cognitive …

Evaluation of sleepiness in space robotics task performance and discussing sleep with high school students in a museum
… Hedges' g (0.35 to 0.74) effect sizes. For a passive monitoring of arm movement primary task, a simple response secondary task metric proved more sensitive to time awake than a two choice response secondary task, but the converse was found when the primary task involved track and capture …

Field Investigation of Stream-Aquifer Interactions: A Case Study in Coastal California
… interrogation of the subsurface, and long-term passive monitoring of aquifer hydraulic heads and stream stage, are reported. Additionally, results of laboratory falling-head permeameter tests and particle size analyses of aquifer sediments, and numerical groundwater flow modeling (MODFLOW) are …

A principled approach to measuring the IoT ecosystem
… which require both active measurements and passive observation to quantify. Furthermore, the IoT devices that are connected to the public Internet may vary from those connected inside home networks, requiring both an external and internal vantage point to draw measurements from. In this …

Systems, models and algorithms for failure diagnosis in networked infrastructure
… high accuracy in a timely manner using practical monitoring telemetry. There are two major challenges in designing such RCA solutions: (1) accurately modeling the behavior of the system and (2) using the model to infer the root causes accurately. Existing works on RCA either (1) fall short in …

Quality of service assessment and analysis of wireless multimedia networks.
… developed. In this method, special artificial monitoring packets were injected into the network. The overall QoS and its parameters were estimated by collecting statistics from these packets. It was possible to make reasonable inferences about the delay, throughput, packet losses and the …
