Ühis- ning erijooni Soome ja Eesti Kaitseliitude puhkpillimuusikas aastatel 1925-1934.

This study focuses on the similarities and differences between the Estonian Defence League and the Finnish Civil Guard brass bands during the period 1925-1934. By 1934 this paramilitary volunteer state defence organisation had reached stability in its development, such that social, cultural and patriotic education of the people - with the help of brass band music among other means- had acquired a significant role, in addition to prioritised military and sports activities. The study begins with introductory paragraphs I and II, which describes the founding of the organisations, their participation in the Wars of Independence and their subsequent peace time activities as well as their representation in the media at the time. The thesis also briefly introduces military music in Finland and Estonia, as well as describes the influence of military music on the Defence League brass bands. The period under review includes the global economic crisis, which undoubtedly concerned the Defence League/Civil Guard and the Lapua and War of Independence movements, which greatly affected the apolitical principles of the organisations. The main emphasis of the thesis is the Defence League/Civil Guard brass band`s musical activities in two counties - Etelä-Pohjanmaa and Pärnumaa, while also including a general overview of the Estonian Defence League brass bands´ activities. One of the most important benefits of the thesis is its introduction of the brass band repertoire in use at the time, which was played by both professional and as well as amateur orchestras the latter of which also included the brass bands of the Defence League/Civil Guard and the Fire Services. Brass band music held a secondary, yet significant position in the Defence League/Civil Guard, where the orchestra as a musical grouping was obliged to perform not only at inner-organisational and national celebrations but also at any event requiring brass band music, such as song festivals, singing days, and other local cultural events. The professional preparation of the band conductors at the beginning of the period under review was not well specialised, but the training of the Defence League/Civil Defence brass band conductors was carried out regularly in both republic according to the opportunities and dedicated training programmes available. The musicians of the Defence League/Civil Defence brass bands were at the same time members of the military organisations as well as amateur musicians, which placed upon them extra demands - they were under close public supervision in all situations. Based on the principle of chronology it appeared that both Finnish and Estonian respective organisations´ brass bands used the gradually improving economic situation for purchasing musical instruments, obtaining repertoire and training musicians/conductors. Despite the fact that brass band music in the Defence League/Civil Guard was considered an amateur activity and a hobby, the more far-reaching objective of the organisation was to resemble the Defence Forces´ orchestras as closely as possible in all aspects. The Defence League/Civil Guard brass band music definitely had a significant influence on forming, developing and enriching music life in both republics. The reviewed nine-year period introduced the musical activities of the Defence League/Civil Guard against the background of the everyday life of the organisation and the need for brass band music and its continuity in the voluntary state defence institutions of both republics.

Faster computation of the Karhunen-Loeve expansion using its domain independence property

The goal of this work is to reduce the cost of computing the coefficients in the Karhunen-Loeve (KL) expansion. The KL expansion serves as a useful and efficient tool for discretizing second-order stochastic processes with known covariance function. Its applications in engineering mechanics include discretizing random field models for elastic moduli, fluid properties, and structural response. The main computational cost of finding the coefficients of this expansion arises from numerically solving an integral eigenvalue problem with the covariance function as the integration kernel. Mathematically this is a homogeneous Fredholm equation of second type. One widely used method for solving this integral eigenvalue problem is to use finite element (FE) bases for discretizing the eigenfunctions, followed by a Galerkin projection. This method is computationally expensive. In the current work it is first shown that the shape of the physical domain in a random field does not affect the realizations of the field estimated using KL expansion, although the individual KL terms are affected. Based on this domain independence property, a numerical integration based scheme accompanied by a modification of the domain, is proposed. In addition to presenting mathematical arguments to establish the domain independence, numerical studies are also conducted to demonstrate and test the proposed method. Numerically it is demonstrated that compared to the Galerkin method the computational speed gain in the proposed method is of three to four orders of magnitude for a two dimensional example, and of one to two orders of magnitude for a three dimensional example, while retaining the same level of accuracy. It is also shown that for separable covariance kernels a further cost reduction of three to four orders of magnitude can be achieved. Both normal and lognormal fields are considered in the numerical studies. (c) 2014 Elsevier B.V. All rights reserved.

On the impact of independence of irrelevant alternatives: the case of two-person NTU games

On several classes of n-person NTU games that have at least one Shapley NTU value, Aumann characterized this solution by six axioms: Non-emptiness, efficiency, unanimity, scale covariance, conditional additivity, and independence of irrelevant alternatives (IIA). Each of the first five axioms is logically independent of the remaining axioms, and the logical independence of IIA is an open problem. We show that for n = 2 the first five axioms already characterize the Shapley NTU value, provided that the class of games is not further restricted. Moreover, we present an example of a solution that satisfies the first five axioms and violates IIA for two-person NTU games (N, V) with uniformly p-smooth V(N).

Conditional independence in quantum many-body systems

In this thesis, I will discuss how information-theoretic arguments can be used to produce sharp bounds in the studies of quantum many-body systems. The main advantage of this approach, as opposed to the conventional field-theoretic argument, is that it depends very little on the precise form of the Hamiltonian. The main idea behind this thesis lies on a number of results concerning the structure of quantum states that are conditionally independent. Depending on the application, some of these statements are generalized to quantum states that are approximately conditionally independent. These structures can be readily used in the studies of gapped quantum many-body systems, especially for the ones in two spatial dimensions. A number of rigorous results are derived, including (i) a universal upper bound for a maximal number of topologically protected states that is expressed in terms of the topological entanglement entropy, (ii) a first-order perturbation bound for the topological entanglement entropy that decays superpolynomially with the size of the subsystem, and (iii) a correlation bound between an arbitrary local operator and a topological operator constructed from a set of local reduced density matrices. I also introduce exactly solvable models supported on a three-dimensional lattice that can be used as a reliable quantum memory.

Independence is elusive: set size effects on encoding precision in visual search.

Looking for a target in a visual scene becomes more difficult as the number of stimuli increases. In a signal detection theory view, this is due to the cumulative effect of noise in the encoding of the distractors, and potentially on top of that, to an increase of the noise (i.e., a decrease of precision) per stimulus with set size, reflecting divided attention. It has long been argued that human visual search behavior can be accounted for by the first factor alone. While such an account seems to be adequate for search tasks in which all distractors have the same, known feature value (i.e., are maximally predictable), we recently found a clear effect of set size on encoding precision when distractors are drawn from a uniform distribution (i.e., when they are maximally unpredictable). Here we interpolate between these two extreme cases to examine which of both conclusions holds more generally as distractor statistics are varied. In one experiment, we vary the level of distractor heterogeneity; in another we dissociate distractor homogeneity from predictability. In all conditions in both experiments, we found a strong decrease of precision with increasing set size, suggesting that precision being independent of set size is the exception rather than the rule.

Design of Photonic Crystal Semiconductor Optical Amplifier With Polarization Independence

Slow-light effects in photonic crystal (PC) waveguides can enhance light-mater interaction near the photonic band edge, which can be used to design a short cavity length semiconductor optical amplifier (SOA). In this paper, a novel SOA based on slow-light effects in PC waveguides (PCSOA) is presented. To realize the amplification of the optical signal with polarization independence, a PCSOA is designed with a compensated structure. The cascaded structure leads to a balanced amplification to the TE and TM polarized light.

Independence of the brittle-ductile transition from the rubber particle size for impact-modified poly(vinyl chloride)

A series of acrylic impact modifiers (AIMS) with different particle sizes ranging from 55.2 to 927.0 nm were synthesized by seeded emulsion polymerization, and the effect of the particle size on the brittle-ductile transition of impact-modified poly(vinyl chloride) (PVC) was investigated. For each AIM, a series of PVC/AIM blends with compositions of 6, 8, 10, 12, and 15 phr AIM in 100 phr PVC were prepared, and the Izod impact strengths of these blends were tested at 23 degrees C. For AIMs with particle sizes of 55.2, 59.8, 125.2, 243.2, and 341.1 nm, the blends fractured in the brittle mode when the concentration of AIM was lower than 10 phr, whereas the blends showed ductile fracture when the AIM concentration reached 10 phr. It was concluded that the brittle-ductile transition of the PVC/AIM blends was independent of the particle size in the range of 55.2-341.1 nm. When the particle size was greater than 341.1 nm, however, the brittle-ductile transition shifted to a higher AIM concentration with an increase in the particle size. Furthermore, the critical interparticle distance was found not to be the criterion of the brittle-ductile transition for the PVC/AIM blends.
