The use of optical emission spectroscopy and specifically the OH(A-X) rotational distribution is investigated to obtain gas temperatures in plasmas in and in contact with liquids. The rotational distribution of OH(A-X) is often non-Boltzmann and only the rotational lines with the smallest rotational numbers are in equilibrium with the gas temperature. The possible reasons of this non-equilibriu...

Stepped spillways are hydraulic structures that, because of their significant capacity in energy dissipation, have been widely used by designers. Flow mechanism over them is complex and many investigations have been performed to study that mechanism. The effect of some parameters such as the number of steps in energy dissipation has not been fully investigated. In this study the latest design c...

In this paper, a thorough review has been presented on the latest research work carried out for the enhancement of machining performance of one of the most commonly used superalloys that is, Inconel 718. The thermal energy has been frequently utilized for improving machinability characteristics of Inconel 718. The review of available literature indicates that plasma, laser, and electric dischar...

The management of urban sewer systems requires data about variability and discharge of typical waste water sources in urban catchments. Especially the infiltration of groundwater and the inflow of surface water (I/I) are important for decisions about rehabilitation and operation of sewer networks. In this paper a new methodology is presented which supports the identification and quantification ...

For time and cost saving reasons, the lowest surface roughness possible is sought in milling operations. High speed milling is recommended in order to minimise the amount of material to be removed in subsequent finishing operations, e.g. grinding, electrical discharge machining or manual polishing. Several roughness parameters are usually employed for the characterization of polished surfaces. ...

Coding of discharge summaries is performed in hospitals daily. We propose to study the impact the use of semantic information may have on this coding. The complementarity of structured medical terminology and medication resource is evaluated on a collection of 1,237 discharge summaries. Performances of the system are improved with the specialization of terminological data.
