Implementation of Bloom Filters in FPGA
Matoušek, Denis ; Kaštil, Jan (referee) ; Žádník, Martin (advisor)
The thesis deals with probabilistic data structure Bloom filter and its modifications - counting Bloom filter and multistage filter. The fundamentals of these data structures are explained and the mathematical equations describing their properties including the equation to minimize the false positive rate are shown. Appropriate hash function is chosen considering an implementation on a FPGA chip. Designs of architectures of the hash function and data structures are implemented in VHDL language and their synthesis is done. Its results are discussed considering occupied resources of a FPGA chip, a critical path and maximum frequency.

Plugin for a Code Risk Analysis
Kvasnička, Jaroslav ; Lengál, Ondřej (referee) ; Havlena, Vojtěch (advisor)
Tato práce se zabývá významem analýzy a testování kódu a jeho dopadem na funkčnost a náklady programu. Pojednává o základních principech a typech testování se zaměřením na statickou analýzu. Zkoumá také platformu Eclipse a zásuvné moduly a architekturu cílového kódu. Dále jsme probrali a implementovali rozšíření statického analyzátoru MFB, který byl vyvinut společností BOC-GROUP, spolu s rozšířeními, jako je kontrola Log4j a analyzátor GDPR. Navrhli jsme a implementovali také zásuvný modul pro Eclipse, který dokáže zvýraznit výsledky analyzátoru MFB v prostředí Eclipse IDE. V závěru jsou také diskutována možná budoucí rozšíření, včetně detektorů škodlivých regulárních výrazů a prevence XSS.

Interpretation of Common Used Tumor Markers Affectedy by Systemic and Inflammatory Diseases

Interpretation of Common Used Tumor Markers Affected by Systemic and Inflammatory Diseases Introduction: An examination of tumor markers is often made as a basis for the successful diagnosis and follow-up treatment of patients with malignant tumors. However, are tumor markers truly significant by themselves, or are they just a baseline quantitative expression of value that we use to diagnose a patient as better or worse based on it increasing or decreasing value? Objective: This paper attempts to answer the question of what factors can affect serum protein and mucin markers and thus lead to a misinterpretation of their results. Methods: Tumor markers were determined by isotopic and non-isotopic laboratory analysis methods, using operational protocols of the immunoanalytic laboratory. All methods were checked using internal quality control, and four times a year using an external quality control. Additionally, 16 236 samples were analysed using 3180 probands during the period 2008-2014. Results: We discovered that in premenopausal women, the markers AFP, CA 125 and HE 4 rise during ovulation peak periods while other markers changed minimally or not at all. However, in postmenopausal women, we proved the incidence of a false positivity marker. With women in the 1st and 2nd trimester of pregnancy, the...
