    Knocking (also knock, detonation, spark knock, pinging or pinking) in spark ignition internal combustion engines occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front. The purpose of this review study is the evaluation of the accuracy of DIAGNOdent in the diagnosis of primary and secondary caries in comparison to conventional methods. Occlusal surface of teeth are one of the areas susceptible to caries while detection of decay in this region is by: 7.

      To date there is no study reported which correlates the impact of magnification on visual- tactile detection of caries using ICDAS- II and a CPI- TN probe. Hence, this study aims to assess the impact of low level magnification in the form of loupes (x) and dental operating microscope (x) on the detection of incipient caries and its impact. @article{osti_, title = {Kinetics of Elementary Processes Relevant to Incipient Soot Formation}, author = {Lin, M C and Heaven, M C}, abstractNote = {Soot formation and abatement processes are some of the most important and challenging problems in hydrocarbon combustion.

This Bureau of Mines report describes the results of a variety of studies of incipient combustion and its detection.

Heated samples of coal, wood, and various polymers were used to evaluate the relative sensitivities of several types of detectors. Criteria of incipient combustion in coal mines. The formation of carbon monoxide (CO) and other gases by various American coals was investigated to determine their relevance to spontaneous heating and to the problem of incipient fire by: 3.

It could be used to detect the incipient faults in the engine. Acoustics-based condition monitoring of systems precisely tries to handle the questions and in the process extracts the relevant information from Cited by: 8.

Finally, case studies on a numerical example and two practical industrial processes are carried out to demonstrate the effectiveness of the proposed incipient fault detection strategies. View Show. Reliable early detection of malfunction and failure of any parts in diesel engines can save the engine from failing completely and save high repair cost.

The aim of this study is to propose an experimental methodology to detect incipient self-ignition processes in solid fuels. This methodology is based on the gases emissions of different solid fuels, varying different factors: sample volume, degree of compaction and grain size of the materials.

The accurate setting of the combustion parameters ensured long-term stability of gas-flow velocity, composition and flame temperature. Incipient soot particles were collected from the flame at a height above the burner (HAB) of 8 by: Types of Studies Reviewed.

The authors reviewed MEDLINE for available literature on new caries detection methodology and tools, using terms such as “early caries detection,” “fluorescence” and “transillumination.” Their review was not a systematic review of the literature. They included in their review in vitro, in situ, in vivo and clinical studies, Cited by: The early and reliable detection of incipient or developing fires is an essential aspect of safety in mines.

ECM is another method proposed for caries detection. Demineralisation, in theory, creates porosities; the porosities will fill with water and ions from saliva causing electrical conductivity changes [].The ECM device employs a single, fixed-frequency alternating current, which attempts to measure the ‘bulk resistance’ of tooth tissue [].The degree of electrical conductance is dictated by Cited by:   The ICDAS II Visual Scoring Criteria: Discussion.

The international caries detection and assessment system (ICDAS) was developed to provide clinicians, epidemiologists and researchers with an evidence-based system, which would permit standardized caries detection and diagnosis in different environments and situations.

13 The ICDAS presents a new paradigm for the measurement of dental. This paper describes a prototype of an automatic diagnosis system whose primary aim is the detection of incipient anomalies in the flame of the boiler of a coal power plant. The system is based on the characterization of the normal behavior of the flame by means of the analysis of its digitalized [email protected]{osti_, title = {Spectroscopic detection, characterization and dynamics of free radicals relevant to combustion processes}, author = {Miller, Terry}, abstractNote = {Combustion chemistry is enormously complex.

The chemical mechanisms involve a multitude of elementary reaction steps and a comparable number of reactive intermediates, many of which are free : Terry Miller.

In many cases a fire can advance through these stages very quickly—sometimes in a matter of minutes, or even seconds. Early warning smoke detectors are designed to detect a fire during the first or second stage by sensing the microscopic and invisible particles that are given off by the fire right after it starts.
