Phishing is an important security issue to the Internet, which has a significant economic impact. The main solution to counteract this threat is currently reactive blacklisting; however, as phishing attacks are mainly performed over short periods of time, reactive methods are too slow. As a result, new approaches to early identify malicious websites are needed. In this paper a new proactive discovery of phishing related domain names is introduced. We mainly focus on the automated detec- tion of possible domain registrations for malicious activities. We leverage techniques coming from natural language modelling in order to build pro- active blacklists. The entries in this list are built using language models and vocabularies encountered in phishing related activities - “secure”, “banking”, brand names, etc. Once a pro-active blacklist is created, ongoing and daily monitoring of only these domains can lead to the efficient detection of phishing web sites.

The main purpose of this Master Thesis was to invent and design Proactive Scenarios that could help students from the University of Luxembourg to improve their social experience on the Moodle™ e-learning platform through the automatic perception of who the user is, where does he/her come from, what are his/her online activities or what do users have in common, and through constant help, guidance and assistance generated by the system with the help of Proactivity. The first part of this work was dedicated to reading, analyzing and comparing stateof- the-art papers, articles and tools in research fields like Proactivity, Communities of Practice, Situation/Context Awareness and Learning Management Systems, followed by the creation and validation of the Proactive Cycle meant to group students, which are inscribed in the same study program or coming from the same city, into social communities where the practice can take multiple shapes.

Legal Design is an umbrella term for merging forward-looking legal thinking with design think- ing. It applies human-centered design to prevent or solve legal problems. Legal Design takes an interdisciplinary and proactive approach to law, covering not only legal information and documents, but also legal services, processes, and systems. This paper introduces Legal Design in the context of forward-looking Legal Tech, especially through the lenses of data protection, and analyses the analogies among Value-Sensitive Design, Proactive Law, and Privacy by Design.

Robots traditionally have a wide array of sensors that allow them to react to the environment and make appropriate decisions. These sensors can give incorrect or imprecise data due to malfunctioning or noise. Sensor fusion methods try to overcome some of these issues by using the data coming from different sensors and combining it. However, they often don’t take sensor malfunctioning and a priori knowledge about the sensors and the environment into account, which can produce conflicting information for the robot to work with. In this paper, we present an architecture and process in order to overcome some of these limitations based on a proactive rule-based system. [less ▲]

Robots have to be able to function in a multitude of different situations and environments. To help them achieve this, they are usually equipped with a large set of sensors whose data will be used in order to make decisions. However, the sensors can malfunction, be influenced by noise or simply be imprecise. Existing sensor fusion techniques can be used in order to overcome some of these problems, but we believe that data can be improved further by computing context information and using a proactive rule-based system to detect potentially conflicting data coming from different sensors. In this paper we will present the architecture and scenarios for a generic model taking context into account. [less ▲]

Exercise training (ET) is one of the decisive and crucial factors for reducing and preventing unexpected cardiac events. The aim of this work is to implement a proactive e-Health system that will allow patients, following a Cardiac Rehabilitation (CR) program outside the hospital, to exercise safely, according to their recommended training zones. The e-Health system includes a smartwatch application, a smartphone application and several server-side applications, working on predefined personalised scenarios, which are alerting, guiding and supporting the patients. The heart rate (HR) of patients is continuously measured, recorded and analysed during ET with the help of wearable devices. While training, patients benefit from multiple levels of feedback. Communities of patients are created for stimulating and motivating patients to perform according to their CR program. Opposed to traditional home-based CR e-Health applications, profiles and training zones are created and handled dynamically for each patient. [less ▲]

In this paper we introduce a new set of general principles for probabilistic abstract argumentation. The main principle is a probabilistic analogue of SCC decomposability, which ensures that the probabilistic evaluation of an argumentation framework complies with the probabilistic (in)dependencies implied by the graph topology. We introduce various examples of probabilistic semantics and determine which principles they satisfy. Our work also provides new insights into the relationship between abstract argumentation and the theory of Bayesian networks. [less ▲]

Generalised polynomial chaos expansion provides a computationally efficient way of quantifying the influence of stochastic parametric uncertainty on the states and outputs of a system. In this study, a polynomial chaos-based method was proposed for an analysis and design of control systems with para-metric uncertainty over a non-hypercube support domain. In the proposed method, the polynomial chaosfor the hypercube domain was extended to non-hypercube domains through proper parameterizationto transform the non-hypercube domains to hypercube domains. Based on the proposed polynomialchaos framework, a constrained optimization problem minimizing the mean under the maximum allow-able variance was formulated for a robust controller design of dynamic systems with the parametricuncertainties of the non-hypercube domain. Several numerical examples ranging from integer to frac-tional order systems were considered to validate the proposed method. The proposed method providedsuperior control performance by avoiding the over-bounds from a hypercube assumption in a compu-tationally efficient manner. From the simulation examples, the computation time by gPC analysis was approximately 10–100 times lower than the traditional approach. [less ▲]

The mixed-criticality toolbox promises system architects a powerful framework for consolidating real-time tasks with different safety properties on a single computing platform. Thanks to the research efforts in the mixed-criticality field, guarantees provided to the highest criticality level are well understood. However, lower-criticality job execution depends on the condition that all high-criticality jobs complete within their more optimistic low-criticality execution time bounds. Otherwise, no guarantees are made. In this paper, we add to the mixed-criticality toolbox by providing a probabilistic analysis method for low-criticality tasks. While deterministic models reduce task behavior to constant numbers, probabilistic analysis captures varying runtime behavior. We introduce a novel algorithmic approach for probabilistic timing analysis, which we call symbolic scheduling. For restricted task sets, we also present an analytical solution. We use this method to calculate per-job success probabilities for low-criticality tasks, in order to quantify, how low-criticality tasks behave in case of high-criticality jobs overrunning their optimistic low-criticality reservation.

There is a generic way to add any new feature to a system. It involves 1) identifying the basic units which build up the system and 2) introducing the new feature to each of these basic units. In the case where the system is argumentation and the feature is probabilistic we have the following. The basic units are: a. the nature of the arguments involved; b. the membership relation in the set S of arguments; c. the attack relation; and d. the choice of extensions. Generically to add a new aspect (probabilistic, or fuzzy, or temporal, etc) to an argumentation network hS, R i can be done by adding this feature to each component a – d. This is a brute-force method and may yield a non-intuitive or meaningful result. A better way is to meaningfully translate the object system into another target system which does have the aspect required and then let the target system endow the aspect on the initial system. In our case we translate argumentation into classical propositional logic and get probabilistic argumentation from the translation. Of course what we get depends on how we translate. In fact, in this paper we introduce probabilistic semantics to abstract argumentation theory based on the equational approach to argumentation networks. We then compare our semantics with existing proposals in the literature including the approaches by M. Thimm and by A. Hunter. Our methodology in general is discussed in the conclusion. [less ▲]
