Schmidt, Róbert ; Maryška, Miloš (advisor) ; Sládek, Pavel (referee)
The main goal of master thesis is to analyze and propose possible low cost Business Intelligence solution with open source technologies and comparison of available tools for implementation in middle size company. We compare Pentaho and Jaspersoft tools implemented on local hardware and cloud environment with Microsoft Azure services. The theoretical part focuses mainly on understanding the business intelligence and its architecture, because architecture is an important part of the work. Actual tools are designed as stand alone modules for specific activities in the business intelligence lifecycle. Low cost tools are often connected with open source technologies and cloud computing. This part of the work contains explanation of these terms and their advantages and disadvantages for our chosen target group of companies. The analytical part includes defined parameters by which it is conducted analysis of tools and their comparison. Business Intelligence solutions are divided according to arcitectural layers. The evaluation criteria are divided into financial, technical and user category. In conclusion, chosen tools are compared and evaluated. The main contribution of this thesis is comparison of open source business intelligence tools for implementation in middle size company. According to the EU directive, middle size company does not exceed 250 employees or profit is less than 50 million euros. The reader can compare the different solutions and their pitfalls or shortcomings that could be critical for the implementation.

Subspace Modeling of Prosodic Features for Speaker Verification
Kockmann, Marcel ; Kenny, Patrick (referee) ; Nöth, Elmar (referee) ; Černocký, Jan (advisor)
Předložená disertační práce se zabývá ověřováním mluvčího pomocí prozodických příznaků zahrnujících hodnoty základního tónu, energie a délek řečových úseků. Studovali jsme dvě rozdílné techniky pro parametrizaci: první vede k dobře definované sadě menšího počtu příznaků, druhá k vysoko-dimenzionální sadě heterogenních prozodických příznaků. První část práce se věnuje vývoji příznaků reprezentujících prozodické kontury, zde jsme vyvinuli a ověřili několik modelovacích technik, s důrazem na modelování v reprezentativních podprostorech. Druhá část práce se zaměřuje na nové pod-prostorové modelovací techniky pro heterogenní prozodické parametry s velkou dimenzionalitou. Model je teoreticky odvozen a experimentálně ověřen na oficiálních datech z NIST evaluací ověřování mluvčího (NIST Speaker Recognition Evaluation). Ve srovnání s ostatními současnými prozodickými jsme dosáhli podstatně lepších výsledků. Na konci práce presentujeme také novou techniku pro elegantní kombinaci dvou prozodických systémů. Tato technika může být použita rovněž pro fúzi prozodického systému se standardním přesným cepstrálním systémem, což vede k dalšímu podstatnému zvýšení úspěšnosti verifikace.

Comparison of mollusc fauna from selected natural reserves on southern Moravia
Bohatá, Lucie ; Vrabec, Vladimír (advisor) ; Jan, Jan (referee)
In this thesis is compared mollusc fauna of six protected areas on the south of Moravia, with characteristic and appraisal of their condition. These protected areas belong to control of BR Lower Moravia and almost all of them belong under control of CHKO Pálava: NPR Cahnov Soutok, NPR Křivé jezero, NPP Pastvisko u Lednice, NPR Ranšpurk, NPR Slanisko u Nesytu, EVL Trkmanské louky. Tested hypothesis was, whether reserves with prevailing of forest cover evince richer faun compare to reserves with prevailing of open space.
Mollusc fauna was collected by individual picking with the aid of flush solid material through strainer and off take of forest soil. Subsequently collected material was inspected in detail, sorted out and determined.
Information about discovered species was compared with the aid of Simpson´s index of domination and Jaccard´s index of similarity and recorded to tables. The biggest index of diversity has NPR Ranšpurk and the lowest has NPR Slanisko u Nesytu according to Simpson´s index. It means that community of molluscs from NPR Ranšpurk is covered same amount of specimen determined species, while on NPR Slanisko u Nesytu was discovered dominance of vulnerable species Anius spirobis (Linné, 1758). According to Jaccard´s index of similarity is the most similar (31%) reserve NPR Křivé jezero and NPR Slanisko u Nesytu and the worst similar (8%) are reserves NPP Pastvisko u Lednice and EVL Trkmanské louky.
Hypothesis was confirmed on the grounds of number of species determined on collected stations and Simpson´s index with bigger diversity on reserves with prevailing of forest cover. According to Jaccard´s index of similarity are forest areas and open areas similar with 66%. The high similarity is consequence of abiotic factors, which influence inspected areas in reserves.

Mophological and molecular diversity of a tropical tree species Guazuma crinita in the Peruvian Amazon
Tuisima Coral, Lady Laura ; Lojka, Bohdan (advisor) ; Helena, Helena (referee)
Fast growing tree species Guazuma crinita (Malvaceae) was selected as a priority species for domestication in the Peruvian Amazon due its important contribution to the livelihood of local farmers. Its domestication process is still in an early age as for many tropical tree species little is known about its genetic variability and we dont know anything about the impact of domestication on its genetic resources. The main objective of this research was to assess the genetic variability of G. crinita within and among populations in the Peruvian Amazon by the use of morphological (wood physical traits) and molecular (ISSR and AFLP) markers.
Wood physical properties among six G. crinita provenances were evaluated. Wood samples were drilled from the base middle and top of the stem of 12 randomly selected eight-years-old trees for determination of wood measurement. Pearson correlations between physical properties were also determined. All wood physical properties except green density differed significantly among provenances. We also found statistically significant variation due to stem level position. The moderately dense wood and the coefficient of anisotropy (1.6) suggested that G. crinita has stable wood; they represent important advantages in terms of costs for transport and transformation process. The results suggested potential to select provenances with desirable wood properties for further breeding and domestication. Due to the variation found even in limited tree samples it is recommended further analysis with more extensive number of samples from different provenances and planting zones.
This research presents the first assessment of genetic variability based on inter-simple sequence repeat (ISSR) markers for 44 G. crinita genotypes from a clonal garden multiplication established in the Peruvian Amazon Research Institute (IIAP) in Ucayali region. Ten ISSR primers amplified a total of 65 bands of which 61 were polymorphic (93.8%). The range of DNA amplification varied from 260 to 2200 bp. Among the provenances overall genetic differentiation (Gst) was 0.03 indicating 97% of genetic diversity within provenances. Gene flow (Nm) was 12.9 alleles per generation. Cluster analysis was not related with geographic origin suggesting a common gene pool which was supported by calculation of weak positive correlation was found between genetic and geographic distance.
With the use of AFLP markers an insight on how domestication process does impact G. crinita genetic resources is also reported on this research work. I was able to generate fingerprint for 58 leaf samples representing eight provenances and three population types, 19 from a natural regenerated population 15 cultivated in home garden nursery and 24 from a collection of genotypes considered as semi-domesticated population. Seven selective AFLP primer combinations were used. A total of 171 fragments were amplified with 99.42% of polymorphism at species level. Each type of population generated fragments with 72.51% 49.12% and 54.39% of polymorphic fragments respectively. Neis genetic diversity and Shannon index information were found to be higher in the population of natural regeneration compared to overall semi-domesticated population (He = 0.10 and 0.9; I = 0.19 and 0.16 respectively). The analysis of molecular variation (AMOVA) showed higher variation within provenances rather than among (84% and 4% respectively). UPGMA clusters analysis and PCoA did not showed correspondence between genetic and geographic distance in addition their correlation was not significant. There was a significant genetic differentiation among types of population suggesting slight genetic bottleneck in semi-domesticated populations yet with relatively high levels of genetic variation.
In situ conservation for populations with high levels of genetic diversity was recommended. In addition proper management of natural regeneration and ex situ genotype collections might be a good conservation strategy to maintain G. crinita genetic resources.
The use of morphological (wood physical traits) and molecular markers were successful to reveal genetic variability of G. crinita and they could be used for other tropical tree species. For further researches it is emphasis to extent the number of samples and geographic scale.
