Poszukiwanie uniwersalnej definicji bezpieczeństwa Polski w niestabilnym systemie Unii Europejskiej opiera się głównie na odnalezieniu się w roli gracza i aktora, który jako samodzielny podmiot bierze aktywny udział w wielowymiarowym unijnym systemie negocjacji i przetargów (brokering between different interests). Polska musi mieć przygotowany swój program działania w UE o charakterze strategicznym i taktycznym włączając w niego państwo-centryczne priorytety horyzontalne i sektorowe, zarówno antykryzysowe jak i antagonistyczne i dysfunkcjonalne. Wymaga to perfekcyjnego przygotowania wykształconego zespołu ludzi zajmujących się bezpieczeństwem. Konieczne są bardzo wysokie umiejętności organizacyjne i wysoki stopień znajomości sposobu funkcjonowania państw w relacjach do całości i poszczególnych elementów UE. Wszystko to sprowadza się do konieczności wypracowywania specyficznego modus operandi polskiego bezpieczeństwa, na który poza znanymi już regułami i procedurami składa się ich interwencyjne zaplecze instytucjonalno-administracyjne oraz logistyczno-techniczne. Polska musi też posiąść zdolność do adaptacji do otaczającego świata (Europy) poprzez poszerzanie bazy funkcjonowania systemu integracyjnego. Wiąże się to bezpośrednio z dostosowywaniem do permanentnej zmiany w Unii Europejskiej i globalnym otoczeniu. Adaptacja jest również istotna z punktu widzenia potrzeby stabilizowania systemu. Pozwala neutralizować wszelkie próby zakłóceń funkcjonalnych jej struktury, pozycji i zbioru kompetencji. Adaptację powinna uzupełniać realistyczna innowacyjność i misyjność Polski widoczna przez wprowadzanie do środowiska (otoczenia) nowych reguł i mechanizmów bezpieczeństwa. Innowacyjność wiąże się z inicjowaniem nowego stylu/sposobu myślenia o bezpieczeństwie, a w związku z tym z nowatorstwem w zakresie wielopoziomowego (wieloprzestrzennego) ujmowania bezpieczeństwa. Na tak rozumiane bezpieczeństwo państwa składa się nie tylko zdolność obronna (militarna), ale także siła gospodarki oraz zasoby, którym Polska powinna dysponować. Misyjność sprowadza się natomiast do promowania i propagowania wartości przypisanych państwu narodowemu - niezapisanych w unijnych traktatach takich jak potęga, racja stanu i niepodległość.

„We are paying a high price for the increasingly unequivocal equation drawn between knowledge and science and ordinary market product. The ideal of perfectly unrestrained cognition, the true mother of science, is threatened by the mass drive towards practical use and application of knowledge, a looming departure into nothingness. Politicians and managers of scientific life are guilty of considerable contribution in corrupting respectable university structures, and thus undermining culture of science and scholarly ethics. (…). Acquisition of funds, sponsorship, media presence, popularisation or even striving for commercial gain are recognised by politicians and scientific consultants, but most of all they are accepted by the university management as objectives worthy of effort, not to say the foremost goals of science. University rectors are nowadays interested primarily in the amounts of acquired moneys. The outcomes of research thus financed is subject to virtually no control, nor does it arouse any interest, unless it turns out to be fit to be announced in the media as a sensation, thereby serving the ‘prestige’ of the university”.

A fundamental task of vision systems is to infer the state of the world given some form of visual observations. From a computational perspective, this often involves facing an ill-posed problem; e.g., information is lost via projection of the 3D world into a 2D image. Solution of an ill-posed problem requires additional information, usually provided as a model of the underlying process. It is important that the model be both computationally feasible as well as theoretically well-founded. In this thesis, a probabilistic, nonlinear supervised computational learning model is proposed: the Specialized Mappings Architecture (SMA). The SMA framework is demonstrated in a computer vision system that can estimate the articulated pose parameters of a human body or human hands, given images obtained via one or more uncalibrated cameras. The SMA consists of several specialized forward mapping functions that are estimated automatically from training data, and a possibly known feedback function. Each specialized function maps certain domains of the input space (e.g., image features) onto the output space (e.g., articulated body parameters). A probabilistic model for the architecture is first formalized. Solutions to key algorithmic problems are then derived: simultaneous learning of the specialized domains along with the mapping functions, as well as performing inference given inputs and a feedback function. The SMA employs a variant of the Expectation-Maximization algorithm and approximate inference. The approach allows the use of alternative conditional independence assumptions for learning and inference, which are derived from a forward model and a feedback model. Experimental validation of the proposed approach is conducted in the task of estimating articulated body pose from image silhouettes. Accuracy and stability of the SMA framework is tested using artificial data sets, as well as synthetic and real video sequences of human bodies and hands.

A common assumption made in traffic matrix (TM) modeling and estimation is independence of a packet's network ingress and egress. We argue that in real IP networks, this assumption should not and does not hold. The fact that most traffic consists of two-way exchanges of packets means that traffic streams flowing in opposite directions at any point in the network are not independent. In this paper we propose a model for traffic matrices based on independence of connections rather than packets. We argue that the independent connection (IC) model is more intuitive, and has a more direct connection to underlying network phenomena than the gravity model. To validate the IC model, we show that it fits real data better than the gravity model and that it works well as a prior in the TM estimation problem. We study the model's parameters empirically and identify useful stability properties. This justifies the use of the simpler versions of the model for TM applications. To illustrate the utility of the model we focus on two such applications: synthetic TM generation and TM estimation. To the best of our knowledge this is the first traffic matrix model that incorporates properties of bidirectional traffic.
