Quantile and probability-level criteria for nonlinear experimental design

International audienceWe consider optimal experimental design for parameter estimation in nonlinear situations where the optimal experiment depends on the value of the parameters to be estimated. Setting a prior distribution for these parameters, we construct criteria based on quantiles and probability levels of classical design criteria and show how their derivatives can easily be approximated, so that classical algorithms for local optimal design can be used for their optimisation

Recommended plant species for school enviroment

Proučavajući gradsko zelenilo posebnu pažnju treba obratiti na školska dvorišta, koja bi u novoj koncepciji škole trebala postati učionice. To su mjesta koja služe za boravak učenika u slobodno vrijeme pa moraju biti uredna, oku ugodna i interesantna. Pogodna za proučavanja brojnih sadržaja vezanih uz nastavu i izvannastavne aktivnosti. Izuzetno je važno kod učenika razvijati pozitivne psihofizičke osobine, poticati usvajanje novih znanja i vještina u zdravom okruženju. Ovakav pristup učenju i ulozi okoliša u odgoju, trebao bi pobuditi interes za prirodno i stvoriti čim ranije što intimniju vezu učenika i prirode.In examining green fields and parks in a city, one must take a closer look at the schoolsyards and playgrounds, which should become open air classrooms in a new school system. These school areas must be clean and appealing to students, who are their primary occupants during the breaks and leisure time activities. In order to encourage motivation to learn, these parks and playgrounds should contain various educational facilities. It is of paramount importance to develop students\u27 physical and mental abilities, expand their capacity to learn new skills and disciplines, all of which will be supported through appropriate schoolyards and parks as part of a comprehensive educational structure. Conducting classes and student activities in school parks will spur the interest in nature among students, helping them develop an appreciation for natural environment and encourage the love and care for nature at an early age

Aircraft Piston Engine Thermodynamics Model of Working Cycle

U ovome završnom radu opisan je rad zrakoplovnog klipnog motora. Definiraju se idealni i realni Ottov ciklus. Prikazan je termodinamički proračun Ottovog ciklusa izabranog zrakoplovnog klipnog motora Lycoming O-320. Također su izračunate ostale vrijednosti pokazatelja procesa kao i stupnjevi iskoristivosti izabranog motora. Izrađeni su dijagrami koji prikazuju ovisnost toplinskog stupnja iskoristivosti o stupnju kompresije za klipne motore i aproksimirani indikatorski dijagram realnog procesa u uvjetima standardne atmosfere na razini mora.The operation of an aircraft piston engine is described in this thesis. The ideal and actual Otto cycle are defined. The thermodynamic calculation of the Otto cycle of the selected Lycoming O-320 aircraft piston engine has been presented. Other process indicator values as well as the utilization rates of the selected engine were also calculated. Diagrams were developed showing the thermal efficiency as a function of compression ratio for piston engines and an approximate indicator diagram of the actual process under conditions of a standard atmosphere at sea level
