Methods for a computation of the optimal value range in interval linear programming
Král, Ondřej ; Hladík, Milan (advisor) ; Novotná, Jana (referee)
This thesis is about the problem of searching an interval that enclose all op- timal values of the objective function in interval linear programming, so called the optimal value range. The solution to this problem is sometimes reduced to solving just a few linear programs but in general it is a hard problem. Af- ter we get familiar with interval arithmetics and when we extend it to linear programming, we define important sets and their properties, B-stability and other connected subproblems. We will extend B-stability to generalized interval linear programming and we will examine methods for computing the optimal value range and we will compare them numerically on random systems. The goal is to implement all mentioned methods in MATLAB/INTLAB and based on numerical results provide one function that will solve this problem, possible efficiently. 1

The total water hardness and pH during the egg development in selected aquarium fish species
FRANTL, Zdeněk
Objectives of thesis: 1.To evaluate the effect of pH and total hardness of water on the development of eggs in aquarium fish Corydoras paleatus, Corydoras paleatus albin, Tanichthys albonubes, Tanichthys albonubes gold, Aphyosemion gardneri, Aphyosemion gardneri gold. 2.Recommendation of optimal values of total hardness of water and pH for successful development of eggs for each monitored aquarium fish. Based on published data in available literature sources and on own experiments, it was evaluated how total water hardness (CM) and pH influences development of aquarium fish eggs of Aphyosemion gardneri, Aphyosemion gardneri gold, Tanichthys albonubes, Tanichthys albonubes gold, Corydoras paleatus, Corydoras paleatus albin.
