"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 paper presents a simple model of debt contracts in order to analyze the conditions under which domestic residents would choose to denominate debts in "dollars". In the model, borrowers are producers of non-traded go...

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...

I extend the traditional Diamond Dybvig framework with aggregate liquidity shocks to small open economies. Currency board may imply perfect risk sharing (with perfect credit markets), contrary to Chang and Velasco's find...

This paper studies the interest-rate-driven business cycles of a small open economy (SOE). For than end a costly operated banking system is added to the standard real-business-cycles model. Banks are the only domestic ag...
