Abstract:
Gas turbine sensors are prone to bias and drift. They may also become unavailable due to maintenance activities or failure through time. It is, therefore, important to correct faulty signal or replace missing sensors with estimated values for improved diagnostic solutions. Coping with a small number of sensors is the most difficult to achieve since this often leads to underdetermined and indistinguishable diagnostic problems in multiple fault scenarios. On the other hand, installing additional sensors has been a controversial issue from cost and weight perspectives. Gas path locations with dif

Abstract:
We study distributed detection and fusion in sensor networks with bathtub-shaped failure (BSF) rate of the sensors which may or not send data to the Fusion Center (FC). The reliability of semiconductor devices is usually represented by the failure rate curve (called the “bathtub curve”), which can be divided into the three following regions: initial failure period, random failure period, and wear-out failure period. Considering the possibility of the failed sensors which still work but in a bad situation, it is unreasonable to trust the data from these sensors. Based on the above situation, we

Abstract:
The Internet of Things (IoT) is expected to provide intelligent services by receiving heterogeneous data from ambient sensors. A mobile device employs a sensor registry system (SRS) to present metadata from ambient sensors, then connects directly for meaningful data. The SRS should provide metadata for sensors that may be successfully connected. This process is location-based and is also known as sensor filtering. In reality, GPS sometimes shows the wrong position and thus leads to a failed connection. We propose a dual collaboration strategy that simultaneously collects GPS readings and predi

For the agricultural food production sector, the control and assessment of food quality is an essential issue, which has a direct impact on both human health and the economic value of the product. One of the fundamental properties from which the quality of the food can be derived is the smell of the product. A significant trend in this context is machine olfaction or the automated simulation of the sense of smell using a so-called electronic nose or e-nose. Hereby, many sensors are used to detect compounds, which define the odors and herewith the quality of the product. The proper assessment o

In order to identify thermal problems in automated machinery, measurement solutions need to continuously monitor variations in temperature. The present push for the usage of IoT devices has led to the introduction of smart invisible temperature measuring systems into many businesses. These systems guarantee that temperature fluctuation trends are continuously logged and fed into the thermal reimbursement mechanism. The sensor infrastructure of a machine may consist of thousands of temperature sensors, according to its size. To repeatedly receive synchronized data from these sensors electronica

Abstract:
Robustness and reliability are two essential network parameters to be given priority in Industrial Wireless Sensor Network. But at the same time it is difficult to achieve gain in these performance metrics. Since in industries these networks are used for monitoring, control and automation processes, therefore, it also requires robust communication with minimum delay. Considering the need of high QoS in Industrial WSN, protocols and standards were developed to fulfil the requirement of reliable data communication in harsh environment. In year 2007, HART community designed a Wireless HART standa

Abstract:
Constant stress amplitude fatigue tests were conducted on the notch pre-cracked Aluminum 7075-T6 rivet hole dog-bone coupons. Monitoring of visible surface crack length by special surface engraving using digital microscope images and by ultrasonic sensors signals was carried out to yield fatigue crack length measurements in relation to number of fatigue cycles applied. The experimental results provided fatigue crack length validation for the ultrasonic sensor measurements. Fracto-graphic examination of failed fatigue surfaces yielded further confirmation of notch pre-crack length and crack gro

Abstract Water main failures are very expensive for municipalities because they typically result in expenses associated with repair costs, flood damage, and loss of revenue to affected businesses. Water main failures also interrupt the operation of vital services, such as medical care and fire-fighting operations. Currently, millions of dollars are spent annually by the water utility industry and by municipalities on the repair of failed components of the water distribution infrastructure, such as components that are made from gray cast iron or "gray iron” pipe and ductile cast iron or "ductil

Abstract The patented electrochemical cell built into a pen permits the non-destructive examination of individual surface areas. The small tip of the pen of approx. 1.5mm2 allows positioning the sensor on any surface geometry and thus achieving locally resolved measurements. So far, the examination of welded pieces was restricted to special fabricated specimens or the analysis of the complete weld and the adjacent surface. The pen-type cell was used to examine welded plates made from standard stainless steel grades. The examination of the weld metal, the heat affected zone and the base materia

Abstract:
Abstract EIS (electrochemical impedance spectroscopy) is well established as a work horse in the laboratory evaluation of organic coatings performance. This paper describes the first step in the development of a test protocol to apply a field-portable ECN (electrochemical noise) sensor / system to the assessment of in-service coatings. The correlation between EIS and ECN scans on long-term lab coating samples confirms that ECN has the ability to discriminate, clearly, between "Good", and "Poor" coatings performance. This may prove useful in extending laboratory EIS data on coatings to field ev

Torque indicating issues continue to plague Power Turbine Modules (PTMs) as a top reason for return. These issues can be linked to failed torque and overspeed sensors and PTM torque reference shaft issues including; sticking shafts due to torque stiction and sheared pins connecting PTM drive shafts to torque reference shafts. At the end of the PTM shaft is the pinning hardware for the torque reference shaft. In shipping and during handling of the PTM damage can occur causing the pin to shear and fail. They can fail due to inadvertent contact with the PTM or torque shaft, during shipping and ha

Abstract:
Accurate gas turbine diagnosis relies on accurate measurements from sensors. Unfortunately, sensors are prone to degradation or failure during gas turbine operations. In this paper a stack of decentralised artificial neural networks are introduced and investigated as an approach to approximate the measurement of a failed sensor once it is detected. Such a system is embedded into a nested neural network system for gas turbine diagnosis. The whole neural network diagnostic system consists of a number of feedforward neural networks for engine component diagnosis, sensor fault detection and isolat

In this 1-year feasibility study, we tried polymerization of several different monomers, commercial as well as novel, specially designed and synthesized for this project in the presence of the nitrate ion to produce imprinted conductive polymers. Polymers 1 and 2 (shown below) produced a response to nitrate, but one inferior to that produced by a polypyrrole (Ppy)-based sensor (which we demonstrated prior to this study). Thus, we elected to proceed with improving the stability of the Ppy-based sensor. In order to improve stability of the Ppy-based sensor, we created a two-layer design which in

In Play It as It Lays by Joan Didion, we are presented with a character in the midst of a crisis of identity. Maria, a failed actress in Hollywood, is beset by many of the problems commonly associated with a rising star in the industry. A reliance on drugs, a commodification of the self, and a deteriorating sense of who she is all play into her downward spiral. Yet when we examine the reason that Maria lacks an actualized sense of self, the reader is presented with a paradox.

After the Cold War, not only the economic discontent created by capitalism and globalization went to the extreme, leaving the environment at the mercy of multinational corporations, but also the perception that the sovereignty, autonomy and independence of nations, and with them, the right to self-determination was increased to a limited extent. In particular, as the global crises of 2008-2009 hit people’s lives hard, the sense of "being left behind" prepared the ground for the demand and supply of populist politics.

This project was based on the hypothesis that nematodes interacting with plants as either parasites or beneficial saprophytes are attracted to their host by natural products. This concept was supported by numerous observations that parasitic nematodes are attracted to root exudates.

Storybook reading to children is considered an efficient way to provide a meaningful context for exposure to unfamiliar words and grammar (Weizman &amp; Snow, 2001). Nonetheless, children with limited language knowledge (e.g., child MTL learners in Singapore) may benefit less from the reading activities, due to the gap between their skills and those required for processing the narration. They often fail to derive the meaning of unknown words/grammar from the verbal context and consequently have trouble figuring out the story plots (Verhallen &amp; Bus, 2010).
