Maintaining the stability of bipedal walking remains a major challenge in humanoid robotics, primarily due to the large number of hyperparameters involved and the need to adapt to dynamic environments and external disturbances. Traditional methods for determining these hyperparameters, such as heuristic approaches, are often time- consuming and potentially suboptimal. In this thesis, we present an integrated approach combining advanced control and reinforcement learning techniques to improve the stability of bipedal walking, particularly in the face of ground disturbances and speed variations. Our main contribution lies in the integration of two complementary approaches: (1) an intrinsically stable model predictive control (IS-MPC) combined with whole-body admittance control, and (2) a reinforcement learning module implemented in the mc_rtc framework. This system allows for continuous mo...

Ramsay Hunt syndrome (RHS) is a rare neurological complication of varicella-zoster virus infection, characterized by peripheral facial paralysis, otalgia, and auricular vesicular lesions. We report the case of a 31-year-old woman presenting with typical symptoms of the syndrome, clinically diagnosed at the General Hospital of Benguela, Angola, in a resource-limited setting. Treatment with acyclovir, prednisone, and supportive measures led to good functional recovery. This case highlights the importance of clinical recognition of RHS in regions with limited access to complementary tests, reinforcing the need for improved diagnostic surveillance and medical training. Keywords: Hunt's syndrome; Herpes Zoster Oticus; Facial Paralysis, Peripheral; Varicella Zoster Virus Infection (Source: MeSH, NLM).

Introducción: El glaucoma es una neuropatía óptica progresiva que daña el nervio óptico y las fibras de la retina. Controlar la presión intraocular es clave para frenar su avance. En casos avanzados o resistentes al tratamiento, se recurre a la trabeculectomía. El tratamiento médico consiste en colirios hipotensores, usados solos o combinados según la gravedad. Sin embargo, la adherencia puede verse afectada por costos y comodidad. Comprender estos tratamientos mejora la calidad de vida y la salud ocular de los pacientes. Objetivos: Describir la eficacia de la trabeculectomía enfocado al mantenimiento de la visión y el impacto en la reducción del costo promedio mensual asociado al uso de gotas hipotensoras en pacientes con glaucoma sometidos a trabeculectomía en el Hospital Nacional Arzobispo Loayza.

The aim of the present work was to optimize the sensorial and technological features of ice cream. The experimental work was performed in two stages: 1) optimization of lactose enzymatic hydrolysis, and 2) optimization of the process and product. For the first stage a complete factorial design was developed, optimized using both response surface and the steepest ascent method. In the second stage a mixture design was performed, combining the process variables. The product with the best sensorial acceptance, high yield and low cost was selected. The acceptance of the product was developed by an untrained taster’s panel. As a main result the sensorial and technological features of the final product were improved, establishing the optimum parameters for its elaboration.

Se intenta determinar si existen diferencias significativas en la riqueza léxica en función del grado escolar y de el tipo de centro educativo, estatal o particular. Con una muestra de 2956 estudiantes a los que se evaluó con la Prueba de Riqueza y de Precisión Léxica construida por André Rey (1962). Se analizaron los datos mediante el análisis factorial de varianza para el efecto individual y combinado y el Análisis de Varianza de un Factor para diseño multigrupo. Se concluye que se confirman ambas hipótesis. Es decir que tanto el colegio de procedencia como el grado de estudios causan diferencias significativas.

Based on the need to make accurate decisions in the face of the COVID-19 pandemic in Peru, pandemic in Peru, specifically for the recovery of the tourism sector. For this purpose, a characterization of the behavior of the pandemic was carried out in the first three months of its development, based on the analysis of trends and the determination of the effective reproduction number (Rt) from statistical-mathematical methods. A variant of the SIR mathematical model was applied to forecast the possible evolution of the pandemic. This model was adjusted with the GlobalSearch optimization strategy of the MATLAB software. His solution used the MATLAB function ode23tb, which uses a combined Runge-Kutta algorithm with a trapezoidal rule algorithm. With the application of the Kaizen strategy as a means of continuous improvement, a set of actions were proposed that could be carried out today and t...

Maximum-minimum bidirectional options are a kind of exotic path dependent options. In the constant elasticity of variance (CEV) model a combining trinomial tree was structured to approximate the nonconstant volatility that is a function of the underlying asset. On this basis a simple and efficient recursive algorithm was developed to compute the risk-neutral probability of each different node for the underlying asset reaching a maximum or minimum price and the total number of maxima (minima) in the trinomial tree. With help of it the computational problems can be effectively solved arising from the inherent complexities of different types of maximum-minimum bidirectional options when the underlying asset evolves as the trinomial CEV model. Numerical results demonstrate the validity and the convergence of the approach mentioned above for the different parameter values set in the trinomial...
