Banking correspondents are a channel through which third parties operate on behalf of a bank, under a contract authorising the provision of some banking services. This model has been implemented extensively in developing countries, as a channel to increase financial inclusion by bringing financial products and services closer to marginalised populations. However, there is a lack of studies on the criteria employed by banks when selecting retailers to turn into banking correspondents (BC), in turn preventing the channel from offering a service portfolio adequate to the capacities of the retailers providing this kind of services, affecting the profitability and sustainability of the channel. The current research parted from the agency theory, which allowed to understand the relationship between the parties involved in the delivery of BC services, seeking to boost financial inclusion in Col...

Many pathological conditions are closely related with an increase in tissue sti ness. For many years, experts performed manual palpation in order to measure elasticity changes, however, this method can only be applied on superficial areas of the human body and provides crude sti ness estimation. Elastography is a technique that attempts to characterize the elastic properties of tissue in order to provide additional and useful information for clinical diagnosis. For more than twenty years, di erent research groups have developed various elastography modalities with a strong interest for quantitative images during the last decade. Recently, comparative studies among di erent elastographic techniques have been performed in order to better characterize biomaterials, to cross-validate several shear wave elastographic modalities and to study the factors that influence their precision and accur...

Deep learning offers new tools to improve our understanding of many important scientific problems. Neutrinos are the most abundant particles in existence and are hypothesized to explain the matter-antimatter asymmetry that dominates our universe. Definitive tests of this conjecture require a detailed understanding of neutrino interactions with a variety of nuclei. Many measurements of interest depend on vertex reconstruction – finding the origin of a neutrino interaction using data from the detector, which can be represented as images. Traditionally, this has been accomplished by utilizing methods that identify the tracks coming from the interaction. However, these methods are not ideal for interactions where an abundance of tracks and cascades occlude the vertex region. Manual algorithm engineering to handle these challenges is complicated and error prone. Deep learning extracts rich,...

In a general parlance, wireless communication tends to be investigated based on the available methods that support enhancing the optimized data link, especially the software-based methods. AI is mainly used to create and design efficient communication network systems and variable node locations. The major factors impacting wireless communications in the current context are enhanced channel frequency, efficiency of using the bandwidth, and modulation type. The software-defined ratio enables collecting the information and analyzing the overall signal-related components and processing them in real-time situations. This will support in detecting unnecessary information and identifying latency at each stage of communication. The study is intended to measure the influence of critical factors in enhancing the overall management of wireless communication systems through the application of AI tec...

The ultrasound has solved the problem of the placentae localization, Still the high cost of ecography attempts its massification. But in this technique we count with equipments that taking advantage of the. Doppler effect inolate the acoustic reflection with notable economic advantage and simplicity in its management that also permits its high diffusion. In the beginning Doppler was used to get cardiac sound of the fetus. Besides this sound, we can appreciate others with this instrument where the placentae blow is an important one. While getting it, we supposed that it was possible to delimit the placentae contour which projection was drawn on the abdominal wall by "map out". The investigation has been taken in the Hospital Docente of Trujillo in a group of 50 pregnants that for got surgical interventions.

The concentration of heavy metals in cocoa crops is currently a serious problem for farmers and producers in various regions of Peru. Exports of cocoa and its derivatives to European markets are threatened by possible evidence of heavy metal contamination in exportable cocoa beans, some at levels higher than those permitted by food regulations established by the European Community, which are aimed at protecting consumers. It is considered that the possible reasons for the contamination of the Cd in cocoa crops may come from natural activities such as volcanic activities, erosion processes and sedimentation in rocks that contain minerals with a high content of these heavy metals. This contamination is also produced by anthropogenic activities such as mining of associated deposits, agriculture (use of fertilizers), smelting of minerals and burning of fossil fuels. Currently, there is no in...

A poco tiempo de empezar el nuevo milenio, los problemas derivados del aprovechamiento y la distribución de la tierra en el departamento de Puno, ubicado en la sierra sur del Perú, parecen no tener solución. En las páginas que siguen intentaremos dar una mirada de conjunto a la problemática que afecta a esta vasta y hermoso región del altiplano peruano; hermosa, pero también poco propicia para el desarrollo de la agricultura y de las propia vida humana. Como muchos de los problemas más complejos que afectan a la sociedad, la realidad de Puno no puede entenderse sin mirar a su historia, plena de detalles en el caso de la tierra, especialmente a todo lo largo de este siglo.

The vehicle routing problem is one of the most studied problems in Operations Re-search. Different variants have been treated in the past 50 years and with technological advances, new challenges appear. In this thesis, we introduce a new variation of the VRP appearing in wireless networks. The new characteristic added to this well-know problem is the possibility of pick-up information via wireless transmissions. In the con-text considered here, a unique base station is connected with the outside and a vehicle is responsible for collecting information via wireless connection to the vehicle when it is located in another sufficiently close station. Simultaneous transmissions are permitted. Time of transmission depends on the distance between stations, the amount of infor-mation transmitted, and other physical factors (e.g obstacles along the way, installed equipment). Information to be sent...
