An asymmetric Abel inversion processing system was developed to establish a method for diagnosing arc plasma that has an elliptical cross section and is non-axisymmetric in the direction perpendicular observation during welding process. This applied tilted tungsten inert gas (TIG) As result, when this intensity distribution due integration, it confirmed relative error near central axis edge lar...

the paper presents results of experimental studies on the methane and propane ignition process in various volumetric compositions of oxidizers heated to temperatures higher than ignition point of analyzed fuels (htac conditions–high temperature air combustion conditions). the increment of temperature dt and the ignition delay time tig are parameters characterizing the process of ignition under ...

Tree insertion grammar (TIG) is a tree-based formalism that makes use of tree substitution and tree adjunction. TIG is related to tree adjoining grammar. However, the adjunction permitted in TIG is su ciently restricted that TIGs only derive context free languages and TIGs have the same cubic-time worst-case complexity bounds for recognition and parsing as context free grammars. An e cient Earl...

A number of formalisms have been proposed in order to restrict tree adjoining grammar (TAG) to be weakly equivalent to context free grammar (CFG): for example, tree substitution grammar (TSG), tree insertion grammar (TIG), and regular-form TAG (RF-TAG); in the other direction, tree-local multicomponent TAG (TL-MCTAG) has been proposed as an extension to TAG which is weakly equivalent to TAG. Th...

This research paper presents hardness, structure and tensile strength analysis of 1460 alloy Al-Cu-Li system, welded joints made by Tungsten Inert Gas (TIG) welding Friction Stir Welding (FSW). Characteristics acoustic noise at the operator workplace during mechanized TIG FSW aluminium-lithium with purpose to develop recommendations for improvement health safety processes were studied. Analyzin...

We define a bidireccional bottom-up parser for Tree Adjoining Grammars (TAG). This parser is a mixture of a defined bidireccional bottom-up parser for TAG and a new parser for Tree Insertion Grammars (TIG) that we present here. We show that the new mixed parser for TAG presents a significative reduction of the theoretical complexity.

BACKGROUND The aim of the study was to present the results of welders' occupational exposure to "blue light" and UV radiation carried out at industrial workstations during TIG and MMA welding. MATERIALS AND METHODS Measurements were performed at 13 workstations (TIG welding: 6; MMA welding: 7), at which different welding parameters and materials were used. The radiation level was measured usi...

LRAT (lecithin:retinol acyltransferase), an enzyme whose levels are modulated during malignant conversion, has been reported as the founder member of a new LRAT-like family that includes tumor suppressors TIG-3(1-164) and Ha-Rev107(1-162). The mechanisms that link these three proteins to carcinogenesis as well as the significance of a reported shared sequence homologous region remain unclear. T...

Calmodulin-binding transcription activator (CAMTA) constitutes one of the most important Ca(2+)/CaM-regulated transcription factor families in plants. Nevertheless, the phylogeny, protein interaction network, and role in nonhost resistance of plant CAMTAs are not well understood. In this study, 200 CAMTA genes were identified from 35 species representing four major plant lineages. The CAMTA gen...
