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.

The Friction Factor: Meeting the Challenges of Modern Aerospace Gimbal Sealing

For as long as radar, weapons targeting, and other electronic systems have been used in aerospace and defense applications, design engineers have employed gimbals as a means to protect them. But sealing these gimbals is a balancing act, requiring the right mix of friction, minimal leak rate and maximum service life.

Would you use drones for home security?

This week's Question: A new home security technology called the Sunflower Home Awareness System deploys a drone to patrol one’s property. The combination of intelligent outdoor sensors and an aerial drone-based camera detects motion, vibration, and sound, and provides users with a view of the home’s real-time surroundings. By analyzing the sensor data, the system can distinguish between a human, a car, and animals. The drone streams video to a smartphone, allowing homeowners to see if their property is at risk. What do you think? Would you use drones for home security?

Thermal Metamaterial for Waste-Heat Harvesting in Power Plants and Factories

The thermal metamaterial was developed in research aimed at efficiently harvesting waste heat from power plants and factories. (Purdue University/Sean Molesky) An international research team has used a thermal metamaterial to control the emission of radiation at high temperatures, an advance that could bring devices able to efficiently harvest waste heat from power plants and factories. Thermophotovoltaic devices that generate electricity from thermal radiation might be adapted to industrial pipes in factories and power plants, as well as on car engines and automotive exhaust systems, to recapture much of the wasted energy.

Technology Powers Implants Wirelessly Via Ultrasound

The basic structure of the ultrasound power supply and communication. (© Photo Fraunhofer IBMT) Scientists have developed a demonstrator that powers active implants wirelessly via ultrasound. Ultrasound waves have a broader range in the body, and they penetrate the implant’s metal casing more easily than electromagnetic waves. The ultrasound waves are also capable of bidirectional transfer of information, such as the temperature of the implant, or details regarding the type and intensity of electrical stimulation.

Renewable Energy Could Be Under Our Feet

Associate Professor Xudong Wang holds a prototype of the researchers’ energy harvesting technology, which uses wood pulp and harnesses nanofibers. (Photo: Stephanie Precourt) Flooring can be made from any number of sustainable materials, making it, generally, an eco-friendly feature in homes and businesses. Now, flooring could be even more “green,” thanks to an inexpensive, simple method developed by University of Wisconsin–Madison materials engineers that allows them to convert footsteps into usable electricity.
