The terms Biker, Punk, Hipster, Goth or Surfer often spark visual depictions of individuals with very distinct fashion styles. These visually salient styles can provide insight into the social identity of an individual. However, despite its potential usefulness, little work has been done to automatically classify images of people into social categories. We tackle this problem by analyzing pictu...

Linked Data is developing towards a large, global repository for structured, interlinked descriptions of real-world entities. An emerging problem in many Web applications making use of data like Linked Data is how a lengthy description can be tailored to the task of quickly identifying the underlying entity. As a solution to this novel problem of entity summarization, we propose RELIN, a varian...

Traditionally Semantic Web applications either included a web crawler or relied on external services to gain access to the Web of Data. Recent efforts, have enabled applications to query the entire Semantic Web for up-to-date results. Such approaches are based on either centralized indexing of semantically annotated metadata or link traversal and URI dereferencing as in the case of Linked Open ...

The Tucuruí Hydro-Power Complex reservoir, Pará State, Amazon Region-Brazil, as well other reservoirs is subject to natural alterations and anthropogenic activities which in turn affect the environmental balance. aim of this work was verify if geostatistical models can be used spatial-temporal evaluation water quality reservoirs. Surfer 13® software interpolate spatial distribution data, two ye...

Computing a 2D colour map of average U-values pixel-by-pixel could become challenging task in terms complexity and time, especially for entire façades under the influence anomalies. In quantitative IRT test, thermal image with resolution 320 × 240 pixels involves 76,800 elements different TWALL each instant “t”. This research aims to create thermographic U-value characterization heavy walls sta...

We study the computation of the straight skeleton of a planar straight-line graph (PSLG) by means of the triangulation-based wavefront propagation proposed by Aichholzer and Aurenhammer in 1998, and provide both theoretical and practical insights. As our main theoretical contribution we explain the algorithmic extensions and modifications of their algorithm necessary for computing the straight ...

Reinforcement learning has gained wide popularity as a technique for simulation-driven approximate dynamic programming. A less known aspect is that the very reasons that make it effective in dynamic programming can also be leveraged for using it for distributed schemes for certain matrix computations involving non-negative matrices. In this spirit, we propose a reinforcement learning algorithm ...

PageRank is one of the principle criteria according to which Google ranks Web pages. PageRank can be interpreted as the frequency that a random surfer visits a Web page, and thus it reflects the popularity of a Web page. We study the effect of newly created links on Google PageRank. We discuss to what extent a page can control its PageRank. Using asymptotic analysis we provide simple conditions...

We propose a web application based security system. When a user interacts with a computing system to enter a secret password, shoulder surfing attacks are of great concern. This system overcomes the problem of shoulder surfing. Previous system proposed a methodology in which the user has to remember all the events performed. This limits the system usage. Our novel approach enhances the shoulder...

The charnockitic and associated granitic rocks of Akure area were studied for their field and petrographic relationship's. The outcrops locations were plotted in Surfer 8. The granitic rock exhibits a porphyritic texture and outcrops in the north-eastern side of the study area while the charnockitics outcrop in the central/western part. An essentially dark coloured and fine grained intrusive ex...
