An Urban Rainfall Storm Flood Severity IndexJobin, Erik 08 May 2013 (has links)
Extreme rainfall statistics are important for the design and management of the water resource infrastructure. The standard approach for extreme rainfall event severity assessment is the Intensity-Duration-Frequency (IDF) method. However, this approach does not consider the spatial context of rainfall and consequently does not properly describe rainfall storm severity, nor rarity. This study provides a critical account of the current standard practice and presents an approach that takes into consideration both the spatial context of rainfall storms, and indirectly incorporates runoff to produce a representative approach to assessing urban rainfall storm severity in terms of flood potential. A stepwise regression analysis was performed on a dataset of individual rainfall storm characteristics to best represent documented basement floodings in the City of Edmonton. Finally, the urban rainfall storm flood severity index was shown to be most representative of the documented basement floodings' severity when compared to that of the IDF method.

Porovnání klasifikačních metod / Comparison of Classification MethodsDočekal, Martin January 2019 (has links)
This thesis deals with a comparison of classification methods. At first, these classification methods based on machine learning are described, then a classifier comparison system is designed and implemented. This thesis also describes some classification tasks and datasets on which the designed system will be tested. The evaluation of classification tasks is done according to standard metrics. In this thesis is presented design and implementation of a classifier that is based on the principle of evolutionary algorithms.

Analýza dat síťové komunikace mobilních zařízení / Analysis of Mobile Devices Network Communication DataAbraham, Lukáš January 2020 (has links)
At the beginning, the work describes DNS and SSL/TLS protocols, it mainly deals with communication between devices using these protocols. Then we'll talk about data preprocessing and data cleaning. Furthermore, the thesis deals with basic data mining techniques such as data classification, association rules, information retrieval, regression analysis and cluster analysis. The next chapter we can read something about how to identify mobile devices on the network. We will evaluate data sets that contain collected data from communication between the above mentioned protocols, which will be used in the practical part. After that, we finally get to the design of a system for analyzing network communication data. We will describe the libraries, which we used and the entire system implementation. We will perform a large number of experiments, which we will finally evaluate.

Israeli military fiction: a narrative in transformationRubinstein, Keren Tova Unknown Date (has links) (PDF)
The current study investigates changing attitudes to militarism within Israeli society since the tumultuous decades following 1948. Events leading to the current state of Israeli society will be traced in order to illustrate the way in which change occurs. The shifts in Israeli history and society during these decades will be examined alongside developments in Israeli literature. Accordingly, eight works of fiction have been selected to lie at the heart of the study. These works, all of which centre around the Israeli military experience, convey an erosion of personal, national, and ideological certainties. The analysis of these works demands three areas of exploration: the depiction of the soldier in the civilian setting, the depiction of the soldier as he interacts with other soldiers in the military sphere, and ‘post-Zionist’ military fiction produced in recent decades. These three areas of exploration entail an interrogation of gender, nationalism, and ‘post-Zionism’ in contemporary Israel. The works examined in the third chapter contain commentary not only upon the social reality of their authors, but also upon the way in which Israeli literature engages with the issues that inform its existence.
