This paper discusses sensor fusion techniques that can be used to increase the control bandwidth and stability of active vibration isolation systems. For this, a low noise inertial instrument dominates the fusion at low frequency to provide vibration isolation. Other types of sensors (relative motion, smaller but noisier inertial, or force sensors) are used at higher frequencies to increase sta...

Bacteria respond to fluctuations in the concentrations of various solutes in their environment by modulating the expression of specific sets of genes. In response to changes in medium osmolarity, for example, Escherichia coli cells change the levels of the outer-membrane porin proteins OmpC and OmpF in a reciprocal manner; in response to nitrogen or phosphate limitation, the cells synthesize pr...

The downscaling of CMOS technology gives rise to a myriad of nanoscale effects. At the same time, power density and thus heat generation increases. The aim of this paper is to evaluate the feasibility of both analogue and digital temperature sensors in nanoscale CMOS using the Berkeley Predictive Technology Model (BPTM) for 65nm. For the oscillator-based digital sensor presented, a sensitivity ...

Usually magnetic bearing consists of an actuator and a levitated object which can be either the rotor of a motor or any other ferromagnetic body. For proper function and to provide stable support, the actuator needs an accurate information about the position of the levitated body which must be given by a sensor. In many applications the displacement sensor with associated wires and cost to be a...

This chapter surveys recent debugging tools for sensor networks that are inspired by data mining algorithms. These tools are motivated by the increased complexity and scale of sensor network applications, making it harder to identify root causes of system problems. At a high level, debugging solutions in the domain of sensor networks can be classified according to their goal into two distinct c...

Some pressure sensor placement methods for leak detection and location in water distribution networks are based on the pressure sensitivity matrix analysis. This matrix depends on the network demands, which are nondeterministic, and the leak magnitudes, which are unknown. In this paper, the robustness of a sensor placement methodology against the fault sensitivity matrix uncertainty is studied....

Whispering gallery mode (WGM) optical microresonators have been shown to be the basis for sensors able to detect minute changes in their environment. This has made them a well-established platform for highly sensitive physical, chemical, and biological sensors. Microbottle resonators (MBR) are a type of WGM optical microresonator. They share characteristics with other, more established, resonat...

Abstract High-performance detection and estimation of gases/odors are challenging, especially in real-time gas sensing applications. Recently, efficient electronic noses (e-noses) being developed using convolutional neural networks (CNNs). Further, CNNs perform better when they operate on a minimal size vector response. In this paper, dimensions the operational vectors have been augmented by vi...
