Model byl klíčový při návrhuThis thesis presents the development and application of a sophisticated numerical model for simulating the propagation of ultrashort laser pulses, with a focus on understanding and optimizing complex nonlinear optical effects. It was instrumental in the design and optimization of the L2-DUHA frontend, particularly in analyzin

Synchronized circuit improves accuracy of fluid transfer measurements

Shut-off valve at the destination of a transferred fluid, improves the accuracy of measurements determining the quantity of liquid transferred from a storage source to a remote location. By synchronizing this valve with the measuring device /totalizer/, the inaccuracies resulting from unfilled transfer lines can be reduced

New grid code for transmission system and its implementation regarding connection of large consumers to the transmission grid

U ovom radu uspoređena su Mrežna pravila elektroenergetskog sustava 2006. godine [1] i Mrežna pravila prijenosnog sustava 2017. godine [2] gdje je posebna pažnja obraćena na priključak velikog potrošača na prijenosnu mrežu. Teorijski je obrađen prijenosni sustav Republike Hrvatske, a zatim se prelazi na proračunski dio. Kod proračunskog dijela smo imali izvođenje simulacije prilikom priključenja potrošača iznosa 20MW i 5MVAr na testnu 14 sabirnički prijenosnu mrežu. Simulacija je izvođena u programu Power World Simulator 19.0 [14]. Nad dobivenim rezultatima je vršena analiza te je donesen zaključak.In this anaysis we studyed and compared The Grid Code of Electric Power System of 2006 and The Grid Code of Transmision System of 2017 where full attention was given on connection of a large consumer on the transmission network. Transmission system of Croatia was theoretically processed and then was moved on budgetary part. Budgetary evidences are result of simulation when connecting consumers of 20MW and 5MVAr to the test 14 bus transmission network. The simulation was performed in Power World Simulator 19.0 [14]. The results obtained were analyzed and a conclusion is given

Positive displacement cylinder measures corrosive liquid volume

Positive displacement cylinder accurately measures volumetric flow rates of corrosive liquids. The cylinder is compatible with corrosive liquids and handles flow rates from zero to 75 gpm at pressures to 900 psig with an accuracy of 0.25 per cent

Biological abilities of storage pests required for the successful penetration of food packages or seeds: Presentation

Storage pests cause enormous damage to stored seed commodities and packaged food. Most of the work published on pest risk assessment concentrates mainly on the effects of “pest –package” or “pest-seed” interactions: i.e. if some species is able (or not able) to penetrate in a sound kernel or package. Based on such “YES-NO outcomes”, the particular stored product pest species is then categorized to either as a “primary” or “secondary” seed feeder; or “penetrator” or “invader” of packages. However, less research attention is paid to the functional explanations of the observed interaction-outcomes. This work therefore deals with comparison of morphological adaptation in various species storage insects with regards to their penetration abilities. For this analysis our original data as well as data from literature were used. As the most important morphological (pre-) adaptations, modulating penetrative/invasive success of storage insect pests, have been recognized: (i) shape and hardness of mandibles, (ii) size and strength of mandibular muscles, (iii) morphology of tarsi enabling climbing and/or firm stance on smooth surfaces. In addition to the morphological adaptations the specific genetically pre-programmed behavioural patterns and abilities may also play a significant role. It will be demonstrated that the above morphological abilities must be taken into account while establishing standard methods of testing of various packages in terms of their sensitivity to penetration/invasion by various species s of storage pests.Storage pests cause enormous damage to stored seed commodities and packaged food.
