Algorithms for Change Point Analysis

Given a series of data, change point analysis involves detecting the number and location of change points, locations in the data where some feature, for example the mean, changes. This has applications in a wide variety of areas, including: Finance, quality control, genetics, environmental studies and medicine. - A brief description linking to NAG Library routines that may help in your applications.

Thermocouple Simulator

The P470 thermocouple simulator is the latest in Highland Technology’s (San Francisco, CA) line of USB and Ethernet-connected Bench-top modules. It features 8 isolated channels, each capable of simulating J, K, E, T, R, S, B, and N thermocouple types, or outputting voltage in a range of ±100 millivolts with 20-bits of resolution. It can also simulate an open thermocouple. Two precision external RTD signal conditioners plus one internal RTD are provided for reference junction temperature sensing.

Edward Chow, AUDREY Program Manager, Jet Propulsion Laboratory, Pasadena, CA

Edward Chow leads the development of AUDREY, the Assistant for Understanding Data through Reasoning, Extraction, and sYnthesis. The artificial-intelligence system captures a variety of sensor data, including gases, temperature, and location signals. By sending alerts through a mobile device or head-mounted display, AUDREY could soon be used to guide first responders through dangerous conditions.

New System Allows Buildings to 'Sense' Internal Damage

Researchers at the Massachusetts Institute of Technology have developed a computational model that makes sense of the ambient vibrations that travel up a structure as trucks and other forces rumble by. By picking out specific features in the noise that give indications of a building’s stability, the model may be used to continuously monitor a building for signs of damage or mechanical stress.

The Economics of Accuracy in Low-cost, High-volume Sensing Applications

Various research firms forecast the market for portable medical devices to be somewhere around the $20 billion-range within the next several years. Part of the increased demand is due to an aging population with more chronic conditions. These smaller portable units requires devices with smaller footprints. By the same token, smaller devices need to provide adequate levels of care to ensure patient safety and comfort. Thus, functionality cannot be sacrificed for space.

Learning the "Keys" of IoT Security

Network-connected devices provide many opportunities to improve and enrich people’s lives, but the “Internet of Things” has a range of definitions. A consumer’s experience with the “IoT” may be a wearable computer for fitness tracking. A physician may place a connected heartbeat monitor on a patient. An industrial engineer may see the Internet of Things as thousands of sensor points that provide measurements of temperatures, pressures, or valve states.
