In this paper we present the operation results of a portable computer-based measurement equipment conceived to perform non-destructive testing of suspicious termite infestations. Its signal processing module is based in the Spectral Kurtosis (SK) and it can be applied to numerous kinds of transients' detection. We introduce the de-noising complement of the discrete wavelet transform (DWT) and we study how can it serves to reduce subjectiveness. The SK pattern allows the targeting of alarms and activity signals. The DWT complements the SK, by keeping the successive approximations of the termite emissions, supposed more non-Gaussian (less noisy) and with less entropy than the detail approximations. For a given mother wavelet, the maximum acceptable level, in the wavelet decomposition tree, which preserves the insects' emissions features, depends on the comparative evolution of the approximations details' entropies, and the value of the global spectral kurtosis associated to the approximation of the separated signals. The paper explains the detection criterion by showing different types of real-life recordings (alarms, activity, and background).

This paper presents our ongoing work in the area of using virtual reality (VR) environments for the integrated systems health management of complex test environments, such as those found in a rocket engine test stand. Specifically, the paper focuses on the design, development and implementation of a hardware-software framework for acquiring, interfacing, integrating and analyzing multiple sensor measurements for display inside of a VR environment. IEEE and OSA-CBM standards are used to design the acquisition and interface methods. Commercial off-the-shelf software is used for analysis and integration. Results demonstrating the application of our method to a rocket engine test stand are presented.

In the perioperative area, the period before and after surgery, it is essential to measure diagnostic parameters such as oxygen saturation, hemoglobin (Hb) concentration and pulse. The Hb concentration in human blood is an important parameter to evaluate the physiological condition. By determining the Hb concentration it is possible to observe imminent postoperative bleeding and autologous retransfusions. Currently, invasive methods are used to measure the Hb concentration. For this purpose blood is taken and analyzed. The disadvantage of this method is the delay between the blood collection and its analysis, which doesn't permit a real-time patient monitoring in critical situations. A non-invasive method allows pain free online patient monitoring with minimum risk of infection and facilitates real time data monitoring allowing immediate clinical reaction to the measured data.

In this paper, the quantitative acoustic field analysis method is suggested for quantitative probe evaluation. A medical ultrasonic probe which is decided abnormal in the development step, is evaluated by using the acoustic pressure distribution measurement system. The NFL (Near Field Length), emission angle, and area parameters are suggested for quantitative analysis. The statistica analysis gives that the range of parameter value of normal channel. The results of experiment shows the similar value of each parameters at normal channel.Sine the result of statistical analysis is very useful, the suggested parameters are will be able to estimate the ultrasonic probe

The paper describes a new sensor to detect termite activity. This is based on an optical light path that is normally blocked by “bait” but becomes transparent following termite activity. The sensor is integrated into a bait station which in turn is part of a wireless sensor network that is able to report status on-line to a host. The sensor has been tested in laboratory and field trials.

Advancement and refinement of technology has resulted in widespread deployment of sensor networks in various facets of human life. Body and home area networks are an embodiment of their steady infiltration in our daily lives. Inherent energy issues with the sensor network technology paradigm have brought an emphasis towards the energy efficiency issue, thereby, propelling researchers to focus on developing topologies with minimal energy consumption constraints. Our work revolves around home area networking in which we have explored a self-organizing clustered topology with a low latency periodic and query-based data collection solution and have proved our proposition to have a significant reduction in terms of energy expenditures.

Recent advances in both technology and science of novel materials have provided the means to study, understand, control, or even manipulate transitional characteristics between isolated atoms and molecules, and bulk materials. Various novel nanoscale materials, devices, and systems with remarkable properties have recently been developed, exhibiting numerous unique applications in chemical and biological sensors, nanophotonics, and in-vivo analysis of cellular processes. Such developments, especially in the last decade, has seeded sector specific focus in areas viz. defense, energy, communication, computing, materials production, textile, health care and medicine. Notwithstanding such advances, perpetual increase in population and thus consumption of fossil fuels has led to increased pollution worldwide a leading contributor to chronic and deadly health disorders and diseases affecting millions of people each year, hence sustainability.
