Transient Detection and Modeling of Continuous Geodetic Data
<p>Transient surface deformation has been observed by continuously operating Global Positioning System stations in the Puget Sound area during the past decade. This surface deformation is associated with processes occurring on or near the subducting plate boundary between the Juan de Fuca and North …

Accelerating radio transient detection using the Bispectrum algorithm and GPGPU
… phenomena. Amongst these phenomena are radio transients. Transients are bursts of electromagnetic radiation and is an exciting area of research as localizing pulsars (transient emitters) allow physicists to test and formulate theories on strong gravitational forces. Current methods for …

A matched filter technique for slow radio transient detection and first demonstration with the Murchison Widefield Array
Many astronomical sources produce transient phenomena at radio frequencies, but the transient sky at low frequencies (< 300 MHz) remain relatively unexplored. Blind surveys with new widefield radio instruments are filling this gap. Although many of these instruments are limited by the classical …

Unattended acoustic sensor systems for noise monitoring in national parks
Detection and classification of transient acoustic signals is a difficult problem. The problem is often complicated by factors such as the variety of sources that may be encountered, the presence of strong interference and substantial variations in the acoustic environment. Furthermore, for most …

High Performance Digital Control Techniques for Powering Microprocessors
… adjustment, non-linear control and a dedicated transient detection circuit is proposed to improve the dynamic performance. The dynamic reference step adjustment method lowers the high speed requirement of reference update clock; the non-linear control minimizes the transient-assertion-to-action …

Machinery diagnostics and characterization through electrical sensing
… Non Intrusive Load Monitoring (NILM) to refine transient detection methods using image classification techniques. Additionally building on the NilmDB framework, a new framework, TransientDB, is proposed which collects and stores information about detected transients for use in machine learning …

Detecting optical transients and variables with MeerLICHT
For a long time, the discovery of a transient in a one wavelength triggered observations in other wavelengths. Due to various constraints such as telescope access, scheduling and availability, and the need for human intervention, follow up observations of the transient event could take place long …

Open Issues in the search for gravitational wave transients
… several issues related to gravitational-wave transient detection from the perspective of the joint all-sky, un-triggered burst search over S5/VSR1 data. Existing searches for gravitational-wave bursts must deal with the presence of non-Gaussian noise transients which populate the data over the …

Machine learning from hard x-ray surveys: applications to magnetic cataclysmic variable studies
… persistent sources and a final one dealing with transients. For the latter, a new transient detection technique is introduced and described: the transient matrix. Finally the performance of the network is assessed and discussed using the testing set and some illustrative source examples. ISINA is …

Investigations in time and of space using the FIRST survey : radio source variability and the evolution of FR II quasars
… reach. A comprehensive search for variable and transient radio sources has been conducted using the ~ 55,000 snapshot images of the FIRST survey. An analysis leading to the discovery of 1,651 variable and transient objects down to mJy levels over a wide range of timescales (few minutes to years) …

Detection and Localization of Pressure Transients in Water Distribution Systems
… monitoring systems in detecting pipe bursts and transient events within water distribution systems. Using PTSNet, a parallel transient simulation Python package, we simulate pipe burst events at each node in a real-world system and examine the pressure-time response at all other nodes. By adding …

Distributed Inference and Learning with Byzantine Data
… inference (or learning) process can be that of detection</p> <p>or estimation or classification, and the topology of the system can be parallel, hierarchical</p> <p>or fully decentralized (peer to peer).</p> <p>Note that, the corrupted data model may seem similar to the scenario where local …
