"The purpose of the present article is to investigate if there exist any such set of temporal stable patterns in temporal series of meteorological variables studying series of air temperature, wind speed and direction an...

"The preliminary results presented in this paper corresponds to a research project oriented to the search of the relationship between the predilection of students concerning learning style and the pedagogical protocols u...

"We present a new method for obtaining the positions of each person attending an outdoor gathering. From this information it is possible to calculate the density field and the number of people. A dual-camera (visible + i...

"There is recent evidence that the core of the Internet, which was formerly dominated by large transit providers, has been reshaped after the transition to a multimedia-oriented network, first by general-purpose CDNs and...

"In spite of the extensive literature on graph databases (GDBs), temporal GDBs have not received too much attention so far. Tempo ral GBDs can capture, for example, the evolution of social networks across time, a releva...

"We present a technique to distinguish valid from invalid data structure objects. The technique is based on building an artificial neural network, more precisely a binary classifier, and training it to identify valid and...

"One of the main challenges in automatic glycemic regulation in patients with type 1 diabetes (T1D) is to dispense with carbohydrate counting. In this context, we propose to equip a previously introduced switched Linear ...

"In this paper we present a criterion for the uniform global asymptotic stability of switched nonlinear systems with time/state-dependent switching constraints but with no dwell-time assumptions. This criterion is based ...

"Background Computer navigation during surgery can help oncologic surgeons perform more accurate resections. However, some navigation studies suggest that this tool may result in unique intraoperative problems and increa...

"We present research work in progress that focuses on data mining tools used for helping teachers to apply a three step knowledge discovering process to diagnose students’ misunderstandings (and their causes) related ...

"This thesis presents the design and implementation of a 3-axis reaction wheel balanced cube capable of balancing on any of its 12 edges. Figure 1 shows a picture of the cube balancing on its edge. The first 3 sections p...

"In this paper a 7-Level Asymmetric Multilevel Current Source Inverter is presented. The topology considers two Current Source Inverters that follow a 1:2 ratio to generate the multilevel current waveform. A Model Predic...

University entrepreneurial ecosystems are key drivers of regional development and technological innovation in Latin America—a region still marked by poverty, unemployment, and inequality (Crespi & Tacsir, 2011). Innova...

"Most of the existing characterizations of the integral input-to-state stability (iISS) property are not suitable for time varying or switched (nonlinear) systems. Previous work by the authors has shown that in such case...

"Vaca Muerta Formation in Neuquén Basin, Argentina, is one of the great worldwide promises given its potential as a non-conventional reservoir. Because of the intrinsic heterogeneity and low permeability, hydraulic frac...

This study proposes a conceptual model to assess innovation capabilities and sustainability outcomes in university-based R&D centers (NACTs) within the AgTech ecosystem. Applying the model to FISFARVET at UNICEN, the res...

This research explores how innovative project management influences operational efficiency and organizational sustainability during the shift toward virtual or hybrid models in Ecuadorian universities. Grounded in theori...

"The goal of this paper is to invite the reader to consider role-playing as a method to train Signal Processing students for professional functions they would undertake in their future careers. Interaction, communication...

"We address aggregate queries over GIS data and moving object data, where non-spatial information is stored in a data warehouse. We propose a formal data model and query language to express complex aggregate queries. Nex...

"In the present work we propose an alternative approach to the state observation problem for Lipschitz continuous systems with open-loop controls. We construct an observer based on a concept of observability weaker than ...

"The General Transit Feed Specication (GTFS) is a data format used to express public transportation schedules and associated geographic information created in 2006 by Google. It is now widely used all around the world in...

"Program repair techniques attempt to fix programs by looking for patches within a search space of fix candidates. These techniques require a specification of the program to be repaired, used as an acceptance criterion f...

"Gravitatonal waves, the seed of the 2015 Nobel’s prize are the cause of several complex celestial phenomena that is non-observable for the naked eye. Their identification, classification and study is s(ll a handmade w...

The Library Linkage Project (PrEBi) has as main objective to share the bibliographic acervus resident in ISTEC Institutions, in order to satisfy the demand of Researchers, Teachers and Students. To manage the bibliograph...
