Justification theory is an abstract unifying formalism that captures semantics of various non-monotonic logics. One intriguing problem has received significant attention the consistency problem: under which conditions are justifications for a fact and its negation suitably related. Two variants justification exist: one in trees they graphs. In this work we resolve once all tree-like setting by ...

background economic consequence analysis is vital for recognizing pipeline comprehensive risk analysis and emergency response planning. objectives the purpose of this study was to estimate economic loss due to fire and explosion in petrochemical feed and product pipelines. materials and methods the present study which performed on 47 pipelines of a petrochemical special zone, pertinent pipeline...

An Ant Colony Optimization (ACO) algorithm is proposed for optimal tree-structured natural gas distribution network. Design of pipelines, facilities, and equipment systems are necessary tasks to configure an optimal natural gas network. A mixed integer programming model is formulated to minimize the total cost in the network. The aim is to optimize pipe diameter sizes so that the location-alloc...

This paper presents a novel approach to aid the operational decision-making of scheduling activities in a real-world pipeline, transporting heavy oil derivatives, which are products of less aggregate value, such as fuel oils, e.g. marine fuel. These products present special characteristics that influence their transport as the impossibility of being transferred at room temperature, due to their...

We present a highly-flexible UIMA-based pipeline for developing structural kernelbased systems for relational learning from text, i.e., for generating training and test data for ranking, classifying short text pairs or measuring similarity between pieces of text. For example, the proposed pipeline can represent an input question and answer sentence pairs as syntacticsemantic structures, enrichi...
