Fusion reactions play a crucial role for several astrophysical scenarios. At the low energies typical of such environments direct measurements of reaction cross sections are very difficult, and even sometimes impossible. In such cases the use of indirect methods can give a substantial help. The Trojan Horse Method (THM) is based on the quasi-free break-up of a nucleus, which can be described in terms of a cluster structure. In such applications the independence of THM results with different break-up schemes, was tested using the quasi free(3)He(Li-6,alpha alpha)H and He-3(Li-7,alpha alpha)H-2 reactions. Results were then compared with the direct behaviours obtained from available data as well as with the cross sections extracted from previous indirect investigations of the same binary reactions using a different nuclide as a Trojan Horse nucleus.

Indirect methods of quarterly estimates of macroeconomic aggregates
Klučka, Jiří ; Hronová, Stanislava (advisor) ; Sixta, Jaroslav (referee)
The aim of my diploma thesis is to describe indirect methods that are used in the compilation of quarterly national accounts. The diploma thesis is divided into three parts and three chapters. The first chapter presents the theoretical background and describes the development of national accounts in the Czech Republic and the basic macroeconomic aggregates. The second chapter is devoted to the quarterly national accounts and mathematical and statistical methods that are used in their compilation. The third chapter describes in detail selected indirect methods, which consists in linking the indicator and aggregate. Consequently, this method is applied to the data of the Czech Republic and then quarterly estimates are constructed which are compared to actual values.
