Abstract An all-optical sensor platform has been developed for hydrocarbon gas composition analysis enabling speciation and quantification of the individual hydrocarbon components in multi-component matrices of alkanes, alkynes, alkenes and/or alcohols. It performs such speciation without requiring physical separation of the compounds as performed in chromatography. The flow-through ...

Maintenance of low oxygen concentration in reflow furnaces produces higher quality product, less product defect, and lower maintenance costs - potentially saving thousands of dollars per year. But only the advent of a unique non-depleting oxygen sensor by Servomex avoids problems with sensor contamination and depletion experienced by traditional sensing technologies. THE ROLE OF OXYGEN ANALYSIS ...

In both municipal and industrial settings, dealing with the organic matter in wastewater can be difficult. As regulations for treated wastewater become more and more stringent, municipalities and commercial/industrial organizations are looking for technology that can meet environmental demands. For organic materials, one of the most effective methods of treatment is integrating a biological ...

Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the ...

This paper describes an application of hybrid multi–criteria decision–making (MCDM) technique for the selection of waste water treatment (WWT) technology for treating wastewater. The proposed approach is based on fuzzy analytical hierarchy process (FAHP) and hierarchy grey relation analysis (GRA) technique. The FAHP is used to determine the weights of criteria and then ranking of the WWT ...

A previous paper has outlined a novel method for estimation of the parameters (including the time delay) of a general Single Input, Single Output (SISO) process model from an appropriate number of arbitrarily specified points on the process frequency response. The method involved combining an analytical approach with a least squares approach using a gradient algorithm, to provide accurate ...

The evaluation of strategic alternatives is particularly a difficult task. This difficulty is due to the complexities inherent in the evaluation process and the lack of structured information. Various analytical and normative models have helped decision makers in strategy selection; however, these models suffer from subjective judgements. This paper proposes an innovative method for ranking ...

The road and rail tunnels are increasing in number. Corresponding to this higher number of tunnels, a higher number of accidents related to safety problems occur. The safety of road and rail tunnels is mostly related to fire safety. Our purpose in this paper is to present a new integrated approach to the analysis of fire safety in tunnels. Using different techniques from the decision support ...

Cargo shipping is a vital part of logistic functions but selecting the right cargo shipping company is a difficult task for companies. This selection can be handled with the help of multi criteria decision making (MCDM) methods. This paper attempts to solve the cargo shipping company selection problem by adopting MCDM model that combines Decision Making Trial and Evaluation Laboratory (DEMATEL) ...

Developments in public policy create new challenges for engineering and engineering education. Analytic and synthetic skills are required to handle the substantive complexities of policy problems, and managerial skills are necessary to design and guide the human interaction processes needed for knowledge integration, multi-party learning and negotiation, and decision-making. The resulting ...

The sustainability concepts of the "Brundtland-Report" and the "Rio documents" call for a combination of ecological, economic, social and institutional aspects of social development. This paper describes briefly, several models of sustainability and discusses social sustainability as conceptualised in selected sustainability indicators. In an attempt to remedy the lack of sociological theory, the ...

This paper presents a hybrid approach based on AHP and belief theory for evaluating sustainable transport solutions. The approach consists of four steps. In the first step, we identify the criteria for evaluating the transport measure. In the second step, we collect data on the criteria from multiple sources and perform data fusion using belief theory. In the third step, we evaluate the state of ...

A new Russian regulatory dispersion model "MEAN" is based on integration of the analytical expressions which approximate the numerical solution of the advection-diffusion equation (ADE). The meteorological preprocessor of this model uses routine information from the national meteorological network to estimate and process necessary dispersion parameters. Turbulent fluxes of the sensible ...
