El artículo analiza el tratamiento de las ideas de tiempo e identidad en dos obras de la ciencia ficción española adscritas, en mayor o menor medida, a los subgéneros del steampunk y del ciberpunk: El mapa del tiempo de Félix J. Palma y Lágrimas en la lluvia de Rosa Montero, respectivamente. El objetivo, una vez repasados los conceptos teóricos fundamentales, es analizar de forma contrastiva las dos novelas, comprobando cómo los universos paralelos y los mundos virtuales constituyen herramientas narrativas que permiten conformar distintas metáforas en torno al tiempo y a la idea de yo a fin de propiciar la reflexión filosófica en el lector.

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...

The article analyses the treatment of the ideas of time and identity in two Spanish science fiction novels which belong, to a greater or lesser degree, to the subgenres of steampunk or cyberpunk: El mapa del tiempo, by Félix J. Palma, and Lágrimas en la lluvia, by Rosa Montero. Once the main theoretical concepts are exposed, the target is to analyse contrastly both novels, by verifying how parallel universes and virtual worlds are used as narrative strategies to create several metaphors on the ideas of time and selfness in order to go in depth in the philosophical reflection in the reader.

El presente trabajo de investigación tiene como ámbito de estudio el régimen público de pensiones de la ley 19990 a partir de su creación en 1973, pero analizado fundamentalmente, a partir de los años noventa cuando paralelamente se creó el sistema privado de pensiones. Esta investigación tiene como objetivo principal y específicos: • Conocer las causas y consecuencias de la sostenibilidad del régimen de pensiones de la ley 19990. • Detectar la tendencia del estancamiento de la pensión que perciben los jubilados de este régimen de jubilación. • Determinar si el monto percibido es adecuado en contraprestación a las aportaciones efectuadas. Lo que se pretende con este trabajo de investigación es contribuir a explicar y analizar críticamente porque el Sistema Nacional coexiste con el Sistema Nacional Privado de Pensiones en un periodo de liberación de la economía nac...

El presente informe analiza los principales problemas jurídicos presentes en la tramitación del procedimiento administrativo trilateral seguido por Azteca contra Enel a cargo de los órganos de solución de controversias de OSIPTEL, recaído en el Expediente N°008-2018-CCO-ST/CI, donde se discute la devolución de supuestos montos cobrados por la empresa eléctrica que superaron el precio máximo legal establecido para el concepto de la contraprestación periódica por acceso y uso de infraestructura eléctrica, concepto regulado en la fórmula reglamentaria establecida bajo el Ley de Banda Ancha. Inicialmente, se analiza la competencia del Cuerpo Colegiado Ad Hoc para resolver las pretensiones de Azteca, en contraposición de lo resuelvo en Laudos Arbitrales emitidos en paralelo, que declaran su propia competencia. En la segunda parte, se analiza la cuestión de fondo de la controver...

The north of Peru is characterized by the presence of world-class porphyry (Cu-Au and Cu-Mo) and epithermal (Au) deposits, located on the west of central Andes, northern Peru. These mines and mineralized deposits are present in a temporal-structural associated with Neogene magmatism with ages from 24 Ma to 7 Ma, intruding silica-clastic rocks from the upper Cretaceous, which, due to the effects of tectonic deformations, particularly in the Cenozoic (Incaica and Quechua phases), led to the occurrence of mega controls Structural problems such as the one proposed in the following publication and hopes to open a window of debate in its environment. Structurally, the deposits in the north of Peru are controlled by mega structural systems that contain the Punre - Canchis fault (Rivera et al., 2008) in the eastern sector as the main structural accident, as well as the system of folds and faults...

The present paper treats about the reuse of the tailing through the shape of an aggregate of construction for the making of bricks ans aggregates of construction. Actually, there is a huge tailing pond in Ticapampa which belongs to the Mining Company Alianza, which has been built near the shore of the Santa river in km 170 and it is parallel to the highway Pativilca-Huaraz, which has a dimension of 750 X 200 meters and it has 19 metres high, which constitute an environment mining passive of high proportions by the huge volume that hás been located near to the área of the Santa River Basin. In that sense, there is a need of formulating solutions for this sort of environment problem which is a national concern and that was the main reason for developing many projects of research at The Ticapampa zone, in charge of a group of researchers from La Universidad Nacional Mayor de San Marcos, w...

Lake Titicaca, at present, is considered a natural wonder of the world. It is the habitat of many unique and endangered native species, with flora and fauna of great diversity, site of nesting of many migratory birds, source of fresh filtered water, by its volume, regulates the air temperature of the region allowing climate conditions less aggressive for life. However, in the last decades, the anthropogenic influence affected its conservation. The problems that Lake Titicaca presents are concentrated in the littoral zone, the bays and the Lake Minor. Large quantities of wastewater that enter directly or poorly treated, in particular to the Bays of Puno and Copacabana, are generating eutrophication processes. The effect of the discharges are the increase of sediments accumulated in the bottom, explosive flowering of Lemna sp. algae on the surface, reduction in dissolved oxygen levels, and...

The aim of this article is to analyse the main factors of excessive prociclicidad of financial systems, due to increased unnecessary fluctuations in the level of activity which puts at risk the financial stability with a negative impact on the real economy of the countries. The normal real economic growth of a country goes in parallel with the growth of financial systems in general and with the growth of appropriations in particular, causing a logical and desirable prociclicidad very strong among these, always putting in evidence as the balances of payments National correspond as interdependent elements of a global monetary system zero-sum. The problem arises to the extent that there are factors inherent in the behaviour of economic agents acting within the financial systems or arising out of prudential regulation which increase volatility in abnormal form on their levels considered fund...

El objetivo de este artículo es analizar los principales factores de la excesiva prociclicidad de los sistemas financieros, debido al incremento innecesario de las oscilaciones en el nivel de actividad, lo cual pone en riesgo la estabilidad financiera con repercusiones negativas en la economía real de los países.El normal crecimiento económico real de un país va en paralelo con el crecimiento de los sistemas financieros en general y con el crecimiento de los créditos en particular, ocasionando una prociclicidad lógica y deseable muy fuerte entre estos, siempre poniendo en evidencia cómo las balanzas de pagos nacionales se corresponden como elementos interdependientes de un sistema monetario global de suma cero.La problemática se plantea en la medida en que existen factores inherentes al comportamiento de los agentes económicos que actúan dentro de los sistemas financieros o qu...

Metal mining is one of the economic pillars of the Peruvian economy. Peru is the main producer of gold, zinc, lead, and tin in Latin America and the second largest producer of copper, silver, and zinc worldwide. Despite its economic importance, mining has also left a plethora of Mining Environmental Liabilities (MEL) whose inadequate waste management represents a risk for both the environment and human health and is a common trigger of social problems. The Cajamarca región is the second región in Peru in terms of the number of MEL sites with the majority of them located in the Hualgayoc district. The goal of the PhD project is the assessment of the environmental impact of MEL in the Peruvian Andes using as an example two post-mining sites in the Hualgayoc district. This evaluation includes the study of soils and native plant species in terms of their metal accumulation potential and th...

En los últimos años, el sector de elevadores se ha caracterizado por una creciente demanda de productos y servicios debido al aumento paralelo de la construcción de edificios comerciales y residenciales, lo que exige a las empresas a ser más exigentes en sus procesos productivos. Asimismo, el diagnóstico inicial reveló una variedad de problemas operativos, como desorden en las áreas de trabajo, tiempos improductivos, paradas de maquinaria, y en general, ausencia de herramientas de control que permitan asegurar la continuidad del proceso. Por ello, es necesario buscar y aplicar nuevas herramientas para optimizar los procesos productivos y disminuir los costos adicionales incurridos para alcanzar el nivel de productividad que exige el mercado nacional. La presente propuesta de mejora basado en el Mantenimiento Productivo Total (TPM), reforzados por la metodología 5S, tiene como obj...
