Septian Gilang Permana Putra, Septian (author)
Credit analysis is required in a wide variety of decision of a modern economy.
It includes understanding the credit risk of small-medium enterprises (SMEs),
which today is the most significant contributor to the economy of almost every
nation. Creditors usually use credit scoring as a tool to predict the probability of
the SMEs to default in the future. The existing methods of SMEs credit scoring
still rely on traditional data, which may require high cost and have low scalabi....................

Venkatasubramanian, Janani (author)
A numerically tractable Stochastic Model Predictive Control (SMPC) strategy using Conditional Value at Risk (CVaR) optimization for discrete-time linear time-invariant systems, with state and input constraints, subject to additive uncertainty, is presented. SMPC strategies make use of the probabilistic description of uncertainty to define chance constraints which allow a certain admissible level of constraint violation. SMPC strategies require the initial state of a system to be within a particu....................

Stoter, Mike (author)
Scarcity of (green) energy resources drives mankind further offshore and towards deeper waters. Protection of subsea infrastructure is of eminent importance in these environments. The key parameter to have a good control over the installation of rock is the falling time. For larger water depths up to 1200 meters, the accuracy of the falling time prediction becomes more important because a small deviation can result in a large difference between prediction and reality.
Offshore and Dredging Engin....................

Schütte, Ernst (author)
Market-oriented electricity sector reforms have spread across the world in the last decades, with the aim to increase efficiency and stimulate investments. In many cases the outcomes of these reforms did not met up with expectations in terms of among others pricing, social welfare and efficiency. An often mentioned reason for these undesired outcomes is that the ‘content’ (the reform, the intervention), did not match the ‘context’ (of a country in which the reforms take place). Egypt is ....................

Inamdar, Jayraj (author)
A detailed modeling of non-gravitational forces is an area that has been left unexplored in the past for orbit modeling of Magellan, primarily due to imperfect knowledge about its attitude and physical properties (optical properties and drag coefficient). As a result, past orbit analyses have restricted the non-gravitational force modeling by implementing a simple cannon-ball model for Magellan. Given that the Venusian surroundings can have significant impact on the spacecraft trajectory, the ma....................

Mandyam Chakravarthy, Akshar (author)
Laminar-turbulent transition (LTT) is the process through which smooth laminar flow transits into chaotic turbulent flow. Investigation of the paths taken to transit into turbulence is a front-runner among other methods followed to characterise turbulent flows. This is of particular importance in aerospace and energy industries for the design of wings and gas turbines. Early research used Linear Stability Theory (LST) to analyse the stability of the flow; with the increase in computational power....................

Hogenhout, Gerard (author)
Worldwide, cardiovascular diseases (e.g. coronary heart disease and stroke) are the leading cause of death. Early detection of cardiac failure symptoms and effective treatment can help reducing health care costs and predict cardiovascular events, which may prevent loss of quality of life, or even loss of life. This early recognition of imminent heart failure is done by evaluating certain risk factors. It is the general assumption that the myocardial stiffness is correlated to diastolic disfuncti....................
|| (2018-09-21) Forecast-driven facility location model for pre-positioning relief goods in preparation for strong typhoons|
Blanco, Quinn (author)
Weather forecast agencies periodically provide information on potential typhoon behavior from its formation to dissipation. This information can be used to pre-position relief goods in areas that are potentially affected by a strong incoming typhoon. The uncertainty of the typhoon behavior with respect to a point location decreases over time, thus showing the trade-off between forecast accuracy and lead time available for pre-positioning. This thesis paper presents a iterative methodology that u....................

Fajar Muhammad Rahman, F. (author)
The new concept of sewer mining which utilizes the ceramic nanofiltration (C-NF) membranes offers a compact solution for water and other resources recovery. However, since it has very limited pre-treatment process, membrane fouling is a common problem due to the direct contact between the membrane and sewage water. Sewage water contains a lot of extracellular polymeric substances (EPS) that can block the membrane pores. One of the most persistent EPS is sodium alginate which responsible for the ....................

Kok, Roy (author)
Crew of small fast ships often experience exces- sive vertical accelerations when sailing in waves, leading to discomfort and injuries. In an attempt to avoid this, in good visibility experienced operators reduce speed voluntarily when they anticipate that the next vertical peak acceleration will be unacceptably large. However, at night and during excessive spray, the operator can hardly see the environment which makes it almost impossible to anticipate wave driven events. On top of that, this a....................

This essay argues that naturalism about mental representations is a failure: the matrix of explanatory requirements, ontological commitments and intuitions in naturalist accounts fails to result in a self-consistent notion of representation. Mental representations are posited to explain an intentional agent’s behaviour and this explanatory role depends crucially on what the representation is about. Therefore it is necessary that representations have determinate content in virtue of which they ....................

In modern political philosophy, utilitarianism is often considered a road once tried and found wanting. A major reason for this is the eminence of John Rawls' Theory of Justice, which provides a number of arguments against it. One of them is the separateness of persons objection, which accuses utilitarianism of viewing separate persons as one, and thus considers the happiness of individuals freely aggregateable and interchangeable. This, it is thought, results in unacceptable consequences in mat....................

Jong, Cecile de
Both δέδεικται and ἐδείχθη are used by Greek mathematical authors in their proofs to refer to something that has already been proved. In this master’s thesis, the use of the passive aorist and the middle perfect in ancient Greek mathematical texts is discussed. The modern interpretations of the verbal aspects in (literary) Greek by Rijksbaron, Sicking and Stork serve as a theoretical framework. I intend to demonstrate that mathematical Greek, despite its dense, formulaic langu....................

In what way can the two seemingly different parts of Isocrates’ Panegyricus be regarded as contributing to a specific goal? This is the question that my thesis will address. On the one hand, Isocrates seems to praise Athens and desire Athenian hegemony, while on the other hand the Panegyricus also advocates panhellenism. This thesis will argue that these two seemingly different parts of the speech can be seen as coherent and do in fact contribute to one goal, by researching Isocrates’ use of....................

Langerak, Lucia Nova Maria
By means of the sign known as Gardiner F27, theory on classification in ancient Egyptian written language is juxtaposed with orthography in both hieroglyphic and hieratic writing. Existing theory, currently a hotly debated topic in Egyptological scholarship, is tested and modified by means of source data primarily from the Ramesside period in Egypt. In this way the thesis opens up promising new avenues for future research.

This thesis aimed to explain the differences between the substitutional and the referential quantifier. It did so firstly by presenting an analysis of the discussion between Wallace and Kripke, secondly by analysing Tarski’s reasons for introducing satisfaction, and finally by looking at whether Kripke’s definition manages to avoid the issues that motivated
Tarski. It concluded that an essential part of the recursive truth-definition given by Kripke is the assumption of a pre-given truth-de....................

Rathour, Mansi; Rathour, Mansi
As the menace of international terror grows, just war theory has been a key topic of speculation in politics, international relations as well as philosophy. While the theory has been framed by the debate between “traditionalists” and “revisionists”, recent discussions seem to have a concern over the integration of jus post bellum. As a result, there has been a neglect towards this necessary third branch of the just war theory. The objective and the desired outcome of just wars is peace. ....................
