While the majority of today’s object class models provide only 2D bounding boxes, far richer output hypotheses are desirable including viewpoint, fine-grained category, and 3D geometry estimate. However, models trained to provide richer output require larger amounts of training data, preferably well covering the relevant aspects such as viewpoint and fine-grained categories. In this paper, we a...

Due to the growing importance and influence of social media, it is timely to gain knowledge about the communication related to technological innovations in the cyberspace. The main goal of the present article is to shed light on the process and structure of information sharing about technologies on Twitter. It identifies the most relevant clusters of actors in the communication, and investigate...

In this study, we investigate and present a new index structure, Triangular Decomposition Tree (TDtree), which can efficiently store and query temporal data in modern database applications. TD-tree is based on spatial representation of interval data and a recursive triangular decomposition of this space. A bounded number of intervals are stored in each leaf of the tree, which hence may be unbal...

This study aims to improve the dietary habits of university students by planting an easy choice.First, we captured the dietary habits of university students by analyzing their purchasing behavior with the data from their meal cards (a prepaid food voucher). As a result of analysis, we found that the dietary habits of meal card users are unbalanced and have many areas for improvement. we also fo...

FACES IV was developed to tap the full continuum of the cohesion and flexibility dimensions from the Circumplex Model of Marital and Family Systems. Six scales were developed, with two balanced scales and four unbalanced scales designed to tap low & high cohesion (disengaged and enmeshed) and flexibility (rigid and chaotic). This study provides initial evidence the six scales in FACES IV are re...

A graph curve is a nodal curve C such that each irreducible component of C is smooth, rational and meets exactly 3 others (Bayer and Eisenbud). Here we classify the graph curves with gonality 1 with respect to balanced line bundles in the sense of L. Caporaso.

In this paper we present a new approach for detecting online pedophiles in chat rooms that combines the results of predictions on the level of the individual post, the level of the user and the level of the entire conversation, and describe the results of this three-stage system in the PAN 2012 competition. Also, we describe a resampling and a filtering strategy to circumvent issues regarding t...
