Leveraging mobile phone-based technologies to provide on-demand adolescent sexual reproductive health information in a resource-limited setting: Kibra, Nairobi County
Adolescents transitioning from childhood to adulthood need to be equipped with reproductive health (SRH) knowledge, skills, attitudes, and values that empower them. The prevalence of pregnancy and STIs among adolescents ...
Applications of biased randomised algorithms and simheuristics to asset and liability management
Asset and Liability Management (ALM) has captured the attention of academics and financial researchers over the last few decades. On the one hand, we need to try to maximise our wealth by taking advantage of the financial ...
Forensic imaging and analysis of Apple iOS devices
In this thesis we present our research on digital forensics on the iOS platform, structured along three areas: forensic imaging; forensic analysis; and anti-forensic techniques. In the field of forensic imaging, we demonstrate ...
Optimizing transportation systems and logistics network configurations: from biased-randomized algorithms to fuzzy simheuristics
Transportation and logistics (T&L) are currently highly relevant functions in any competitive industry. Locating facilities or distributing goods to hundreds or thousands of customers are activities with a high degree of ...
IoT@run-time: a model-based approach to support deployment and self-adaptations in IoT systems
Today, most Internet of Things (IoT) systems leverage edge and fog computing to meet increasingly restrictive requirements and improve quality of service (QoS). Although these multi-layer architectures can improve system ...
Image steganalysis and steganography in the spatial domain
In this dissertation, we propose different novel techniques both to detect hidden information (steganalysis) and to hide information (steganography). These techniques are presented in the form of a collection of five ...
Enterprise reference architectures for higher education institutions: Analysis, comparison and practical uses
Enterprise Architecture (EA) is currently accepted as one on the major instruments for enabling organisations in their transformation processes to achieve business-technology alignment. Despite that over the last years EA ...
Applications of the Internet of Things and optimization to inventory and distribution management
This thesis is part of the IoFEED (EU funded) project, which aims to monitor approximately 325 farm bins and investigates business processes carried out between farmers and animal feed producers. We propose a computer-aided ...
Applications of biased-randomized algorithms and simheuristics in integrated logistics
Transportation and logistics (T&L) activities play a vital role in the development of many businesses from different industries. With the increasing number of people living in urban areas, the expansion of on-demand economy ...
Gesture tracking and neural activity segmentation in head-fixed behaving mice by deep learning methods
The typical approach used by neuroscientists is to study the response of laboratory animals to a stimulus while recording their neural activity at the same time. With the advent of calcium imaging technology, researchers ...
Structural and dynamical interdependencies in complex networks at meso- and macroscale: nestedness, modularity, and in-block nestedness
Many real systems like the brain are considered to be complex, i.e. they are made of several interacting components and display a collective behaviour that cannot be inferred from how the individual parts behave. They are ...
Ad-hoc formation of edge clouds over heterogeneous non-dedicated resources
La proliferació de dispositius connectats ha assolit xifres enormes. Avui, els dispositius connectats no tan sols estan disponibles a qualsevol lloc, sinó que, a més, adquireixen ràpidament una gran complexitat en la seva ...
Human body parts segmentation via stacked and multi-task learning
La segmentació de persones en imatges RGB ha estat un problema central en el camp de la visió per computador. En aquesta tesi abordem el problema mitjançant hand-crafted features en un pipeline de dues etapes tant per ...
Visual scene context in emotion perception
Els estudis psicològics demostren que el context de l'escena, a més de l'expressió facial i la postura corporal, aporta informació important a la nostra percepció de les emocions de les persones. Tot i això, el processament ...
Towards assessing information privacy in microblogging online social networks. The IPAM framework
Les xarxes socials en línia incorporen diferents formes de comunicació interactiva com serveis de microblogs, compartició de fitxers multimèdia o xarxes de contactes professionals. En els últims anys han augmentat els ...
From metaheuristics to learnheuristics: Applications to logistics, finance, and computing
Un gran nombre de processos de presa de decisions en sectors estratègics com el transport i la producció representen problemes NP-difícils. Sovint, aquests processos es caracteritzen per alts nivells d'incertesa i dinamisme. ...
Model-driven round-trip engineering of REST APIs
Les API web s'han convertit cada vegada més en un actiu clau per a les empreses, que n'han promogut la implementació i la integració en les seves activitats quotidianes. A la pràctica, la majoria d'aquestes API web són ...
A metaheuristic and simheuristic approach for the p-HUB median problem from a telecommunication perspective
Els últims avenços en la indústria de les telecomunicacions ofereixen grans oportunitats per a ciutadans i organitzacions en un món globalment connectat, però alhora presenten reptes als quals s'enfronten tècnics i enginyers ...
Simheuristics to support efficient and sustainable freight transportation in smart city logistics
La logística urbana intel·ligent constitueix un factor crucial en la creació de sistemes de transport urbà eficients i sostenibles. Entre altres factors, aquests sistemes es centren en la incorporació de dades en temps ...
Using ubiquitous computing for preventing risk behaviors based on smart contexts through mobile devices: an approach for nutrition and sexually transmitted diseases
Darrerament s'han fet servir diversos mètodes per a educar persones i comunitats sobre temes relacionats amb problemes mundials de salut, entre els quals hi ha la nutrició i els comportaments sexuals. En l'àmbit de la ...
