Tailored Supported Nickel Nanoparticle Catalysts for Dry Reforming of Methane via a Molecular Approach
(2017)Dry reforming of methane (DRM) has become a very appealing reaction in the last decades because it allows a valorization of un-wanted greenhouse gases (CO2, CH4) toward syn-gas production. It is often use in industry as complementary process of steam reforming of methane (SRM) process in order to tune effectively the product composition (H2/CO), which ease the syn-gas conversion to synthetic fuel. Supported nickel nanoparticles (Ni NPs) ...Doctoral Thesis -
Resistive Multiplexed Micromegas Detectors to Search for Dark Sector Physics and Test the Weak Equivalence Principle for Anti-Matter at CERN
(2017)The experiments NA64 and GBAR aiming to explore the still unanswered questions in physics of the existence of dark matter and the matter- antimatter asymmetry, respectively, are presented in the scope of this thesis. NA64 is an experiment at CERN searching for a new U0(1) gauge boson, A0 (dark photon) which may mediate the interaction of dark matter with ordinary matter via a very weak force. The experiment is sensitive to the still ...Doctoral Thesis -
A Constructive Treatment of Enhanced Encryption Schemes
(2017)Encryption is a tool that has traditionally been used to allow confidential communication between two parties. Over the years, several types of encryption have been proposed, including public-key encryption, identity-based encryption, deniable encryption, and functional encryption. These variants provide different features and security guarantees. Their security is typically defined by a game between an adversary and a challenger. Even ...Doctoral Thesis -
Ion-Flow Environment of HVDC and Hybrid AC/DC Overhead Lines
(2017)For various applications, HVDC overhead lines (OHL) offer technical and economic advantages over conventional HVAC systems. Boosted by increased demand for transmission capacity, the number of HVDC systems has thus steadily risen over the past decades. Corona effects - processes related to partial electric discharges caused by high electric field stresses at conductor surfaces - are an important factor in the overall environmental, technical ...Doctoral Thesis -

Optimization-based motion generation for multiped robots in contact scenarios
(2017)The introduction of legged robots into society has the potential to impact many aspects of our lives. The versatile morphology of robots with arms and legs, or multipeds, allows them to operate in a broad spectrum of environments. For example, legged robots could assist at construction sites or locomote in rocky terrain under persistent interaction with the environment through contact. These behaviors require algorithms that translate ...Doctoral Thesis -
Statistical Reverse-Engineering of Signal Transduction Pathways
(2017)Inferring cell signaling networks from high-throughput data is a challenging problem in systems biology. Signaling networks are stochastic in nature. They are not entirely predictable based on the limited information available on the system. Recent advances in cytometric technology enable us to measure the abundance level of a large number of proteins at the single-cell level across time. Traditional network reconstruction approaches ...Doctoral Thesis -
The Essential Role of de Novo Fatty Acid Synthesis in CNS Myelin Regeneration
(2017)A variety of pathological conditions of the central nervous system (CNS) are associated with demyelination and loss of myelinating oligodendrocytes, e.g. spinal cord injury, stroke, and primary demyelinating diseases such as multiple sclerosis (MS). Common to all of these pathologies is the intrinsic, yet variable, capacity of the CNS to regenerate damaged myelin sheaths, resulting in the restoration of saltatory conduction and neuroprotection. ...Doctoral Thesis
