Další kapitola se zabývá přístrojem Seaward Mace a podrobnějšímu popisu zkoušek odolnosti. V poslední části je popsán zkoušený přístroj a realizace zkoušek v prostorách laboratoře elektrických měření Ústavu automatizace a meříící techniky FEKTThe bachelor thesis deals with electromagnetic compatibility. Beginning of this thesis is devoted to general problems of EMC. Next part refers of the various tests for robustness. The next chapter deals with device Seaward Mace and a more detailed description of the resistance tests. The last part describes the test apparatus and implementation tests in the laboratory measurement of the Institute of Electrical Control and Instrumentation FEEC

N,N′-Bis(2,3-dimethoxy­benzyl­idene)propane-1,3-diamine

The title compound, C21H26N2O4, adopts an E configuration with respect to the azomethine C=N bonds. The dihedral angle between the two rings is 8.16 (8)°. The crystal structure is stabilized by weak inter­molecular C—H⋯O inter­actions

10,16-Dichloro-6,20-dioxa-3,23-diaza­tetra­cyclo­[23.3.1.07,12.014,19]nona­cosa-1(29),7,9,11,14(19),15,17,25,27-nona­ene-4,22-dione methanol monosolvate

In the title compound, C25H22Cl2N2O4·CH3OH, the macrocyclic mol­ecule adopts a slightly distorted C 2-symmetric conformation. The macrocyclic mol­ecules are linked via N—H⋯O hydrogen bonds between the amide groups into chains extending along the [010] direction. The methanol mol­ecules bridge these chains via N—H⋯O and O—H⋯O hydrogen bonds with the formation of a two-dimensional polymeric structure parallel to (001). The methanol mol­ecule is disordered over two positions with the occupancy ratio of 9:1. The disorder of the solvent molecule is caused by weak intermolecular C—H⋯Cl hydrogen bonding

(E)-N-(2,4-Dimeth­oxy­benzyl­idene)-4-ethoxyaniline

In the title compound, C17H19NO3, the mol­ecule has an E configuration with respect to the C=N bond and the dihedral angle between the aromatic rings is 56.07 (5)°. In the crystal, inversion dimers linked by pairs of C—H⋯O hydrogen bonds occur. The dimers are linked by weak C—H⋯π inter­actions, forming a three-dimensional network

2,17-Dichloro-8,9,10,11-tetra­hydro-19H-dibenzo[k,n][1,10,4,7]dioxadiaza­cyclo­penta­decine-7,12(6H,13H)-dione

In the crystal structure of the title compound, C19H18Cl2N2O4, N—H⋯O hydrogen bonds link the mol­ecules into infinite chains along the b axis. The structure also features weak C—H⋯O and C—H⋯Cl hydrogen bonds and C—H⋯π and (lone pair)⋯π inter­actions [Cl⋯centroid = 3.5871 (7) Å]. An intra­molecular N—H⋯O bond occurs

Dibromido[bis­(η5-cyclo­penta­dien­yl)dimethyl­silane]zirconium(IV)

The title mol­ecule, [ZrBr2(C12H14Si)], possesses a crystallographically imposed twofold rotational symmetry with the rotation axis passing through the Zr and Si atoms. The ZrIV centre is in a distorted tetra­hedral environment defined by two Cp rings of chelating organic ligands and two Br anions. Two five-membered rings form a dihedral angle of 59.7 (2)°. Unequal Zr—C bonds [2.471 (3)–2.556 (3) Å] in the mol­ecule indicate that the inter­action of the central metal with the [(C5H4)2SiMe2]2− ligand contains noticeable η3-allyl and η2-olefin contributions
