A STUDY ON INTERROGATION SYSTEM FOR GEORESOURCE USING RESOURCE DESCRIPTION FRAMEWORK

A STUDY ON INTERROGATION SYSTEM FOR GEORESOURCE USING RESOURCE DESCRIPTION FRAMEWORK

Abstract- Ontology’s use standard machine-readable languages to explicitly define the formal semantics of concepts and their relationships in a domain. Resource Description framework for interrogation system will require the domain expert knowledge and data owner authentication as well as the appropriate ontology prediction. For Spatial Data Ontology based information retrieval will be complex due to the nature of ontology. So the new mechanism is proposed for the ontology frame work for geo-spatial data's. For this one, the resource description Framework (RDF) ontology for accessing the geo spatial data. Due to the complexity of RDF access, the application of N-Triple algorithm for Convert the RDF data's in to the subject, Object, Predicates is applied. This will improve the accuracy of the Information retrieval from the both domain expert and the data owners based on flexible query from user.

An Interrogation System for Spectrally Multiplexed Fiber Bragg Grating Sensors

An Interrogation System for Spectrally Multiplexed Fiber Bragg Grating Sensors

ABSTRACT: Structural Health Monitoring (SHM) is emerged as a multidisciplinary set of technologies with the goal of reducing maintenance as well as the implementation costs of aircraft structures. By the implementation of automatic load monitoring and damage detection, systems which are able to detect incipient cracks well below the critical size are developed without any human intervention. In recent years, fiber optic sensors particularly those based on Fiber Bragg Grating (FBG) have been proved to be a potentially excellent technique for real-time monitoring of these structures. In this paper, a FBG interrogation system based on an intensity demodulation and demultiplexing of an arrayed waveguide grating (AWG) module is analyzed. The main benefit of this system is it has no moving parts; hence the speed of operation can be very high. The sensing element is configured in reflecting mode and is illuminated by a broad-band light source through an optical fiber. The output spectrum of the sensor is analyzed using an arrayed waveguide grating device containing integral photodetectors. From this the strain and temperature are monitored.

A Low-power Fiber Bragg Grating Sensor Interrogation System for High-speed Sensing.

This research develops a low-power, high speed interrogation system for interrogating fiber Bragg grating (FBG) strain sensors under dynamic loading of mechanical and aerospace structures. The interrogation system is based on a vertical cavity surface emitting laser (VCSEL) light source. To achieve this goal, the multiplexing capacity of FBG sensors using a narrow bandwidth light source is first maximized. Specifically, a spectral profile division multiplexing technique is derived to track each FBG wavelength shift in a serially multiplexed FBG network. Each sensor in the network is uniquely characterized by its own reflected spectrum shape, thus spectral overlapping is allowed in the wavelength domain. Spectral distortion caused by multiple reflections and spectral shadowing between FBG sensors that occur in serial topology sensor networks, are considered in the identification algorithm. A nonlinear optimization function based on the output spectrum is constructed. Next, the feasibility of using the developed interrogation technique in shape sensing of Kevlar woven fabrics is demonstrated. To back out the surface deflection of a central loaded circularly clamped dry woven fabric, a finite element model exceptionally considering edge slipping effect was developed to understand fabric deformation. Due to fabric edge slipping, large deflection level of the fabric, a modified empirical

Novel fault location in MTDC grids with non-homogeneous transmission lines utilizing distributed current sensing technology

Novel fault location in MTDC grids with non-homogeneous transmission lines utilizing distributed current sensing technology

The FBG peak wavelength shifts were monitored by a dedicated commercial FBG interrogation system (‘Sensors in- terrogator’ in Fig. 12) capable of acquiring the sensors spectra at 5 kHz. As such, the proposed fault location algorithm could only be demonstrated and practically validated at this relatively low sampling frequency. Nevertheless, the principle of operation and robustness of the proposed scheme has been fully validated (for all the three stages of the algorithm) even though with slightly lower accuracy of fault location. It should be noted, however, that the acquisition frequency limit of 5 kHz is strictly due to the FBG interrogator currently available for the experiments. Higher sampling rates can be achieved when alternative interrogators are employed, such as a solid state interrogator based on an Arrayed Waveguide Grating (AWG) previously developed by the authors [29], [30]. In such a case, the limiting factor for high speed operation would be the performance of the employed data acquisition and signal processing electronics, but scanning frequencies greater than 100 kHz can readily be achieved and the accuracy of the developed fault location prototype could be improved significantly.

Design and construction of an interrogation unit for fiber Bragg grating sensor system

Design and construction of an interrogation unit for fiber Bragg grating sensor system

Fiber optic sensors are commonly used nowadays in civil structure and medical applications as well as in research. This is due to the ability of fiber optic sensors exceeding the ability of other sensors in terms of sensitivity, precision and the ability to be multiplexed in a large network of sensors such as for a large area landslide monitoring. One popular applications of fiber optic technology is the use of in core Fiber Bragg grating (FBG). FBG sensors are very sensitive to parameters such as strain and temperature. Unfortunately the high sensitivity demanded interrogation system that has the same resolution capability. This thesis mainly discusses on the development of an interrogation system for FBG using a wavelength filter method. The works also cover a simulation coding program using Matlab® that has been developed for a tunable filter around 1310 nm to studies the characteristics of a Fabry Perot (FP) filter. The complete interrogation system based on wavelength filter method is developed using other optical components including broadband source, coupler, wavelength filter and photodetector. The photodetector and wavelength filter are interface to a personal computer (PC) for the purpose of tuning at a certain wavelength and photodetector collecting the optical power. By scanning the whole spectrum and collecting the power of each individual wavelength, λ ; the λ Bragg from

All-Optical Interrogation of Neural Circuits

All-Optical Interrogation of Neural Circuits

Third, all-optical experiments bring exciting new opportu- nities for closed-loop control of neural circuits. Historically, system feedback in optogenetics had been achieved chiefly with electrical or behavioral system readouts (Sohal et al., 2009; Leifer et al., 2011; Stirman et al., 2011; O’Connor et al., 2013; Paz et al., 2013; Krook-Magnuson et al., 2014; Siegle and Wilson, 2014; Grosenick et al., 2015; Newman et al., 2015). However, optical feedback from a genetically targeted popu- lation could allow real-time adjustment of optogenetic input to achieve a desired waveform of activity in the controlled population in vivo during behavior, accounting for all of the system variability associated with varying brain states, activity history, local field potential (LFP) rhythm phase, and so on. Moreover, testing models of the circuit itself becomes much more swift and rigorous with closed-loop methods for system identification. Extracting useful information (to be fed back in the closed loop) from imaging data is computationally harder (and slower, problematically so for this question) than with a single time-varying scalar that the electrical readouts such as LFP provide. However, even as computational methods prog-

High Sensitivity 'Hot-wire'-based Gas Velocity Sensor for safe monitoring in mining applications

High Sensitivity 'Hot-wire'-based Gas Velocity Sensor for safe monitoring in mining applications

Three different versions of the fiber-optical hot-wire sensor probe, based on the schematic design shown in Figure 2, were manufactured and evaluated, and designated Probes 1, 2 and 3. Probes 1 and 3 were copper sleeved, with lengths of 13mm and 18mm respectively and Probe 2 was used with a Teflon sleeving. The probes were tested in the wind tunnel which was home built and capable of generating wind velocities in the range of 0.2 – 8m/s (which could be measured with a conventional device for cross-calibration to an accuracy ≤0.1m/s). With no wind blowing (<0.2 m/s i.e. still air), the power of the pump light source was adjusted so that the co-doped fiber absorbs the pump laser to allow photothermal conversion to occur and set the ‘baseline’ conditions. As a result of heat then being transmitted, the FBG in the other fiber experiences a wavelength shift (due to this heating effect). With the system set up in this way, a series of experiments was carried out to determine the magnitude of the wavelength shift as a function of the applied optical power to the co-doped fiber, this being done for the three probe designs discussed, and results obtained are shown in Figure 4.

Diectromagnetic interrogation techniques for damage detection

Diectromagnetic interrogation techniques for damage detection

In this paper we presented a reduced order computational algorithm which contributes to the overall field of nondestructive evaluation. In detecting subsurface damages, there is a need for a fast and efficient inverse problem methodology. The reduced order POD method is an attractive method, because it allowed us to create a reduced basis of less than 10 basis elements in the trials presented while still capturing 99% of the total energy of the system. This results in an accurate, as well as fast, forward algorithm.

Probe-based three-dimensional confocal laser endomicroscopy of brain tumors: technical note

Probe-based three-dimensional confocal laser endomicroscopy of brain tumors: technical note

We also assessed patient biopsy samples acquired dur- ing resections of brain tumors. Patients (n = 31) underwent surgery for brain tumor resection with or without 10% FNa intravenously injected intraoperatively and fluorescence guid- ance using the Yellow 560 mode of the OPMI Pentero 900 microscope (Carl Zeiss AG). Biopsy specimens from patients who received FNa (n = 22) intraoperatively originated from the fluorescent tumor areas and were then imaged in the operative room with a stand-alone CLE system within 1–10 minutes after specimen acquisition. Specimens from the patients who did not receive FNa (n = 9) were received in the pathology department and stained topically with 0.1% acridine (AO) or 0.1% acriflavine (AF) (Table 1). After CLE imaging, speci- mens were placed into cassettes and submitted to pathology for processing and H&E staining.

Torture and coercive interrogation: A critical discussion

Torture and coercive interrogation: A critical discussion

Many of the arguments outlined in the ‘Torture: The Case For’ section above assume that coercive interrogational practices are guaranteed to produce results; they focus upon the moral and legal aspects of the debate, whilst ignoring those based upon logic and empiricism; they overlook what is arguably the most important factor; whether torture actually works. If it could be demonstrated that it does not, then the majority of the arguments supporting torture may be rendered obsolete. Goldman summarises that the issue of the effectiveness of enhanced interrogation is central to public debate on torture, because ‘apologists often assume that torture works, and all that is left is the moral justification. [However] If torture does not work, then their apology is irrelevant’, 344 as the

System Safety Practice: An Interrogation of Practitioners about Their Activities, Challenges, and Views with a Focus on the European Region

System Safety Practice: An Interrogation of Practitioners about Their Activities, Challenges, and Views with a Focus on the European Region

The last page of our questionnaire contains a text field for gen- eral feedback. One issue, the participants criticised, pertains to the scope and the terminology used in the questionnaire: The respondents noted that the inquiry is general and does not account for the diversity of safety practices in various in- dustries. Some questions rely on a particular interpretation of safety practice leaving assumptions implicit and risking to get in conflict with other views of system safety, for example, “safety by introduction of controls” versus “safety assurance and assessment.” Moreover, some of the questions are hard to answer because of a lack of standardised terminology across domains and because of missing topics, for example, legal safety requirements and regulations, human operators, socio- technical systems were not mentioned.

interrogation. 81 One told the Al Sweady Inquiry that he was physically pushed around, that the interrogator yelled constantly and that he eventually made a false admission to stop the interrogator’s accusations. 82 These detainees had previously suffered ill-treatment and ‘threatening and oppressive tactical questioning’ at Camp Abu Naji, which gave them an incentive to try to end the JFIT’s interrogations quickly by telling the interrogators what they wanted to hear. 83 The Al Sweady Inquiry rejected the allegations that they were shouted at and questioned aggressively during the JFIT’s interrogations, concluding that these claims were lies and exaggerations. 84 Their interrogations, although uncomfortable, were not as extreme as the commonly-held conception of interrogation in the ‘War on Terror’. The alleged and actual extreme practices used in connection with interrogation in the ‘War on Terror’ have received much media attention. Given their seriousness, this is right: pressure should arguably be placed on governments to investigate allegations of mistreatment, ascertain the truth and take action to prevent reoccurrences of unjustified and illegal practices. However, findings that allegations are untrue are often deemed less newsworthy than the original allegations, leaving the public with an inaccurate picture of the treatment of detainees held for interrogation.

Plasmonic Sensor Based on Dielectric Nanoprisms

Plasmonic Sensor Based on Dielectric Nanoprisms

A periodic array of extruded nanoprisms is proposed to generate surface plasmon resonances for sensing applications. Nanoprisms guide and funnel light towards the metal-dielectric interface where the dielectric acts as the medium under test. The system works under normal incidence conditions and is spectrally interrogated. The performance is better than the classical Kretschmann configurations, and the values of sensitivity and figure of merit are competitive with other plasmonic sensor technologies. The geometry and the choice of materials have been made taking into account applicable fabrication constraints.

related to the interrogation rights. For example, almost half of students believed that they had to answer all of the questions asked by a police officer. They also found a small positive correlation between comprehension level and grade level. The aforementioned research suggests that the legislative reforms relating to youth interrogation rights may not have mitigated youth vulnerabilities. That is, the waiver forms may not allow the majority of youth—particularly those in lower grades—to knowingly and intelligently make decisions regarding whether to invoke or waive their rights. Research on juveniles’ understanding of Miranda warnings in the United States has also showed low comprehension levels, with lower age and lower IQ scores, being associated with greater deficits in comprehension (e.g., Goldstein, Condie, Kalbeitzer, Osman, & Geier, 2003 ; Grisso, 1981 ; Viljoen, Zapf, & Roesch, 2007 ).
