a model satisfies a property– verified properties must be those a system should possess– informal justification always accompanies formal verification)  Two types of simulation (– interactive simulation(user is in complete control; user determines individual simulation steps; execution events are GUI visible)– automatic simulation (user specifies number of execution steps in the GUI; and/or user sets a number of stop criteria and breakpoints; simulator makes random choices without user interaction; only the resulting state is shown via the GUI; a simulation report contains results)) 3. A Single-example protocol/ Net structure  The transport layer(– ensures reliable transmissions between hosts – the sender transfers data packagets to a receiver – unreliable communication network– use of sequence numbers, acknowledgements, retransmissions)

1 Abstract In IT Security world, there is lack of available, reliable systems for measuring security levels/posture. They lack the range of quantitative measurements and easy and fast deployment, and potentially affects companies of all sizes. Readily available security standards provide qualitative security levels, but not quantitative results – that would be easily comparable. This deficiency makes it hard for companies to evaluate their security posture accurately. Absence of security metrics makes it complicated for customers to select the appropriate measures for particular security level needed. The research question for this research project is – “How is it possible to calculate IT security effectiveness?”. The aim of this research is to use this reference model to calculate and to optimize major university’s and a small CSP-s (Cloud Service Provider) security posture and their spending’s on security measures

A phone is represented between brackets Allophone: e.g. pin ­ spin Phoneme: /p/ - /iz/ `houses' /s/ voicless `cats' /z/ `boys' /t/ `learned' /id/ `wanted' A phoneme is the smallest unit of the sound system of a language. If two sounds have the same phoneme, they are treated equally. A phoneme is represented between slashes.

pills detection and classification. Basically (in almost all the methods) the starting point consists of digital images of pilled fabrics. These images (representing either pilled fabric specimens to be evaluated or standard reference) are, then, processed in several different ways in order to extract some features describing fabric pilling. Finally, such parameters are used for grading the fabrics or for characterizing their quality. While the starting point and the final results are ultimately shared by all the techniques, what changes is the method adopted for extracting the information used for pilling grading. On the basis of main literature works, in the present work the following categories are identified: 1) 2D imaging methods based on thresholding. 2) 2D imaging methods based on Fourier and/or Wavelet analysis. 3) 3D imaging methods. 4) AI-based methods (using either 2D or 3D images).

result of the exchange of the phoneme c and f.  Morphology - The study of word formations and the internal structure of words.  Morphemes – the smallest units of language that have their own meaning or grammatical function. Morphemes can be bound or free. Free morphemes are morphemes that can appear alone and carry and meaning. For example: dog, cat, work, also articles.

This means that the variation of the received power due to fading can be suppressed by the transmission power control. 17. Selgita paari lausega HARQ (Hybrid Automatic Repeat Request) tööpõhimõtet. Hybrid Automatic Repeat-Request • uses incremental redundancy • user data is transmitted multiple times using different codings • user device saves packet and combines it later with the retransmission *Even if the retransmitted packets are corrupted, their combination can yield an error-free packet • Scheme combining ARQ and Forward Error Correction • FEC decoding based on all unsuccessful transmissions • Stop-and-Wait (SAW) protocol • Two basic schemes -Chase Combining * same data block is sent at each retransmission - Incremental Redundancy (IR) * Additional Redundant Information sent at each retransmission Töö põhimõte kokkuvõtvalt ARQ:

x -U t A U sin h = y x -U t 2 cosh + A cos h h 2. What advantages gives equations for vorticity transport and streamfuction in comparison with standard equations for velocity field? In what cases these advantages are often used? Vorticity transport depends on the three Partial differential equations (PDEs) for u, v and p in the "primitive variable" form. Stream function depends on only two Partial differential equations (PDEs) for the scalars and . We win on variables and this is the main advantage. 3. How will change vorticity transport equation if Reynold number will increase? Then Re number increase, it means, that we have turbulent flow. In this conditions Navier-Stokes equation take form of Euler equation. Navier-Stokes equation consist of two parts. One part, that consist volume becomes greater and equation transform into linear
