Integration of detailed stratigraphic, sedimentologic and tectonic studies of the Río Cañete Basin with opening and divergence rates of the South Atlantic Ocean, overriding plate velocity, trench migration, subducting age (Fig. 1) etc. and the protracted Mesozoic Farallon Plate oblique convergence parameters provide new lines of evidence to suggest an alternative model for the evolution of the Peruvian margin. These unorthodox model departures significantly from the classic and simplistic Andean Model used in the literature. The western margin of Gondwana experience severe lithosphere extension coeval with arc magmatism since at least Middle Triassic. Actually, only the uppermost Jurassic unit is displayed along the Río Cañete Basin, however, it is important to take into account that northward the Jurassic arc sequence terminates against the accreted Amotape/Olmos Terrain and it over...

Academic self-efficacy is a powerful predictor of academic success, yet there are several factors that predispose it. Because of this, an explanatory model is proposed using the self-regulation of academic activities, positive affection, and personality. Hierarchical multiple linear regression was used to support the predictive proposal of the model. The Specific Perceived Self-Efficacy Scale of Academic Situations, The Scale of Positive and Negative Experience, Subscale Self-Regulation of Activities of the Academic Procrastination Scale, and Mini International Personality Item Pool (MINI-IPIP) were used. High correlations were obtained in the self-regulation of activities, positive affection, and personality (extraversion, concientousness and openness to experience) to academic self-efficacy. The final predictive model explained 30.1% of the total variance of academic self-efficacy. In ...

In recent years, the number of applications of model predictive control (MPC) is rapidly increasing due to the better control performance that it provides in comparison to traditional control methods. However, the main limitation of MPC is the computational e ort required for the online solution of an optimization problem. This shortcoming restricts the use of MPC for real-time control of dynamic systems with high sampling rates. This thesis aims to overcome this limitation by implementing high-performance MPC solvers for real-time control of fast systems. Hence, one of the objectives of this work is to take the advantage of the particular mathematical structures that MPC schemes exhibit and use parallel computing to improve the computational e ciency. Firstly, this thesis focuses on implementing e cient parallel solvers for linear MPC (LMPC) problems, which are described by block-struct...

In this work, the design of symmetric OTAs with low transconductance value (nA/V order) and their application in low frequency and low power is presented. For this aim, the series-parallel (S-P) mirrors was used, which divided the differential pair transconductance. With this technique, a 1 nA/V transconductor is reached. Techniques for extend the linear range (hundreds milivolts) of the differential pair will presented too. The Advanced Compact MOSFET Model ACM was used in the design process. These symmetric OTAs designed will be used in active filters with low central frequency, for biomedical applications (EEG signals). The capacitors of this filters are in the picofaradads order, and are off chip. These OTAs and filters were designed in 0.8 um standard technology. These techniques that we will present will be validated through simulation

In the search for non-destructive inspection forms in fruit quality, in recent years there have been increased studies on the use of hyperspectral images in their quality. The objective of this investigation was to evaluate the level of prediction of quality parameters and maturity stage of the “Kent” mango by a model obtained using hyperspectral images. 120 mangoes were stored at four different temperatures (10, 12.5, 15 and 17.5 °C) at which images of both sides were taken in the near infrared range (890 - 1710 nm), one per day, for 12 days and with two repetitions for each fruit. Parallel to the taking of images, quality parameters such as firmness, color (ΔE*), brix degrees and moisture content were determined in the same mangoes. To obtain the model, the quality attributes were correlated with 70% of the spectral data resulting from the images using the partial least squares r...

This thesis focuses on the importance of the study of development at the regional level, with the main purpose of analyzing and defining how public investment relates to economic growth and inequality in the La Libertad region for the 2000 period - 2015. The hypothesis around which this work revolved was that public investment is directly related to economic growth and inversely with inequality in the La Libertad region, in the period 2000-2015. This research takes the annual data of Public Investment, GDP per capita and Gini Coefficient, to describe the evolution of each variable in La Libertad for the period covered by the present. It analyzes and defines, from the data collected and ordered, the evolution of the public investment in the region, the trend that it takes throughout the period and the sectors in which it was most invested, besides describing the participation of each leve...

In this paper, the main objective was the preliminary study of the High Speed Rail Line - LIFAVE, included in the Trujillo - Lima section, constituted under an integral approach in its development, which was based on the use of the hierarchical analytical process - PAJ, as a percentage measurement instrument between LIFAVE and road transport (conventional transport). The process was carried out in parallel under five fronts: the preliminary design of the LIFAVE was developed, which led to the use of thirteen digital elevation models (ASTER GDEM) designed by NASA and the Ministry of Economy, Trade and Industry of Japan (METI) ), then delimited and geo processed the data in the ArcGis and AutoCAD Civil 3D softwar, obtaining as a result the plant design of the LIFAVE axis; the socioeconomic study was carried out, considering six points of analysis (travel time, road safety, intermodality, s...
