This paper aims to undertake a systemic analysis of civil construction verify whether public investments made from 2007 onwards were able increase the sector's productive linkages in Brazilian economy. For this, hypothetical extraction method input-output matrix and official matrices country 2005 2015 are used. The results show that importance structure sector - total exceeds 7.42% GDP 10.06% 2...

Open-Pit Production Scheduling (OPPS) problem focuses on determining a block sequencing and scheduling to maximize Net Present Value (NPV) of the venture under constraints. The scheduling model is critically sensitive to the economic value volatility of block, block weight, and operational capacity. In order to deal with the OPPS uncertainties, various approaches can be recommended. Robust opti...

The last few decades has witnessed a stupendous growth of information across the internet. The giant of information are unused across the globe and it requires rigid methodology to mine and extract the text. The growth of information is increasing exponentially and it becomes more important to detect useful pattern from the data. It is very difficult for the user to retrieve the data from the d...

We present a new feature extraction method for noisy datasets with intricate spatio-temporal structures that is based on the concept of transport operators graphs. The proposed approach generalizes and extends many existing data representation methodologies built upon diffusion processes to domain where dynamical systems play key role. main advantage this comes from ability exploit different re...

Recognizing and supporting human activities is an important challenge for ambient assisted living. In this paper we introduce a novel argumentation-based approach for dealing with human activity recognition. By considering a model of the world and a set of observations of the world, hypothetical fragments of activities are built. The hypothetical fragments of activities will be goal-oriented ac...

Intelligence analysis is the process of reasoning about information in order to produce hypothetical explanations for a situation. In this process, it is fundamental to assess how, when, and where this information has been elaborated. A model of provenance can capture this contextual information. Provenance data inevitably affects the identification of plausible conclusions, thus, it must be in...
