Data Mining for the Security of Cyber Physical Systems Using Deep-Learning Methods
2022
Cyber Physical Systems (CPSs) have become widely popular in recent years, and their applicability have been growing exponentially. A CPS is an advanced system that incorporates a computation unit along with a hardware unit, allowing for computing processes to interact with the physical world. However, this increased usage has also led to the security concerns in them, as they allow potential attack vendors to exploit the possibilities of committing misconduct for their own benefit. It is of paramount importance that these systems have comprehensive security mechanisms to mitigate these security threats. A typical attack vector for a CPS is malicious data supplied by compromised sensors that…
Application of a Knowledge Discovery Process to Study Instances of Capacitated Vehicle Routing Problems
2020
Vehicle Routing Problems (VRP) are computationally challenging, constrained optimization problems, which have central role in logistics management. Usually different solvers are being developed and applied for different kind of problems. However, if descriptive and general features could be extracted to describe such problems and their solution attempts, then one could apply data mining and machine learning methods in order to discover general knowledge on such problems. The aim then would be to improve understanding of the most important characteristics of VRPs from both efficient solution and utilization points of view. The purpose of this article is to address these challenges by proposi…
Classification of Sound Scenes and Events in Real-World Scenarios with Deep Learning Techniques
2021
La clasificación de los eventos sonoros es un campo de la audición por computador que se está volviendo cada vez más interesante debido al gran número de aplicaciones que podrían beneficiarse de esta tecnología. A diferencia de otros campos de la audición por computador relacionados con la recuperación de información musical o el reconocimiento del habla, la clasificación de eventos sonoros tiene una serie de problemas intrínsecos. Estos problemas son la naturaleza polifónica de la mayoría de las grabaciones de sonido ambiental, la diferencia en la naturaleza de cada sonido, la falta de estructura temporal y la adición de ruido de fondo y reverberación en el proceso de grabación. Estos prob…
Los límites de la intervención social. Investigación narrativa y mejora de la práctica profesional
2014
La tesis parte de la observación de una creciente dificultad de los servicios sociales para obtener resultados significativos en el campo de la pobreza y la exclusión social. Esta situación parece apuntar, una vez atendidas las razones de orden político y económico, a la posibilidad de que existan ciertos límites en la capacidad de la intervención social para modificar y mejorar los problemas sobre los que actúa. Dichos límites son comprendidos en primera instancia como un conjunto de datos que muestran que pese al incremento de la inversión en servicios de intervención social, la evolución de algunos indicadores de pobreza y exclusión no parecen mejorar en la extensión, intensidad y estabi…

Promuovere l'autostima, l'autoefficacia e lo stile decisionale a scuola attraverso la scrittura espressiva
2015
Esprimere in forma scritta le proprie emozioni positive quando si pensa ai propri obiettivi di vita fa bene alla salute. È questa la conclusione cui è giunta laura King dopo aver analizzato gli effetti della trascrizione del proprio miglior sé proiettato nel futuro. James W. Pennebaker, pioniere della scrittura espressiva sperimentata secondo la modalità retrospettiva, ha invece sottolineato gli effetti sulla salute della scrittura di emozioni negative connesse ad episodi traumatici vissuti nel passato. Nel presente studio, si sono presi in considerazione i contributi dei due ricercatori per confrontare gli effetti della trascrizione delle paure e delle speranze riguardo al futuro su tre co…
Identification of phytopathogenic bacteria in maize seeds in Ukraine
2018
The main bacterial diseases of maize: bacterial wilt of maize (Pantoea stewartii subsp. stewartii), goss’s bacterial wilt (Clavibacter michiganensis subsp. nebraskensis), seed rot-seedling blight of maize (Bacillus subtilis), bacterial spot of maize (Pseudomonas syringae pv. syringae), bacterial leaf spot of maize (Pantoea agglomerans) and bacterial stalk rot of maize caused by several causative agents, were described. The causative agents of these diseases are often stored and transmitted with seeds, so seed analysis for the presence of phytopathogenic bacteria is an important step in the pathogen control system. For analysis, the corn seeds that were grown in the Poltava and Kiev regions …
Network Capacity Estimators Predicting QoE in HTTP Adaptive Streaming
2022
The aim of adaptive HTTP streaming technology is preserving the best possible video streaming quality for viewers in heterogeneous network conditions. This can be achieved by making multiple quality versions of the video available. Switching between versions during playback should be imperceptible and fluent. The decision about quality-level switching is typically based on network capacity estimation and buffer occupancy, which predict the risk of stalling. Since quality-level switching and stalling are directly evident to the user, they are often classified as influence factors of quality of experience (QoE). In this paper, we observe different network capacity estimators and buffer behavi…
Energy conversion efficiency in betavoltaic cells based on the diamond Schottky diode with a thin drift layer
2020
The HPHT diamond Schottky diode was assembled as a Metal/Intrinsic/p-doped structure betavoltaic cell (BC) with a very thin (1 μm) drift layer and tested under 5–30 keV electron beam irradiation using a scanning electron microscope (SEM). The effect of the β-radiation energy and the backscattering of electrons on the energy conversion was studied. From the results obtained, it is shown that, the efficiency of the investigated BC increases from 1.01 to 3.75% with the decrease of β-particle energy from 30 to 5 keV due to an increase of the electron beam absorption in a thin drift layer. Maximum efficiency is achieved when the electron beam energy is close to the average β-decay energy of 3H. …
Preparation and characterisation of optical and optoelectronic devices based in two-dimensional semiconductors
2020
In the Materials Science field, two-dimensional materials have gained the scientific community attention in recent years. The change and the appearance of novel properties when their thickness is reduced to nanometric scale has special interest for its fundamental properties study for, from this base, the design and its implementation in devices. The wide variety of materials with the possibility of being exfoliated at the two-dimensional level opens the field to different applications, from optoelectronic devices, detection and sensing, energy storage, catalysis, medical applications and quantum information technologies, among others. This thesis gathers results in both directions: a funda…
