Sinkroni generator u radu na elektroenergetski sustav (EES) izrazito je nelinearan sto je glavno ogranicenje primjene konvencionalnih linearnih stabilizatora EES-a. Optimalni regulator može se realizirati primjenom neuronskih mreža. Primjenom Adaptive Critic Design (ACD) algoritma optimiranja koji je zasnovan na dinamickom programiranju i neuronskim mrežama osiguravaju se dobre karakteristike u citavom radnom opsegu. S izvedenim algoritmom upravljanja, izveden je simulacijski proracun i mjerenje na realnom sustavu.

U tijeku je zamjena sustava uzbude i zastita sva cetiri generatora u HE Miljacka. Predviđeni opseg radova i usluga za zamjenu sustava zastita generatora, te potrebne dorade sustava procesnog upravljanja ukljucuje: snimanje stanja, izradu izvedbenog projekta i prilagodnog projekta ugradnje i uklapanja predmentnih sustava u postrojenje generatora, proizvodnju opreme te tvornicku montažu i ispitivanje, demontažu postojecih te montažu novih sustava i opreme, funkcionalno ispitivanje i pustanje u rad. U referatu se isticu: pojedinosti zamjene opreme i znacajke novog sustava zastita generatora, potrebne prilagodbe ostatka postrojenja HE, povezivanje sustava zastita na postojeci sustav upravljanja, redosljed projektiranja i zamjene opreme, uklapanje nove opreme u predefinirane gabarite prostorija.

U sklopu projekta zamjene turbina i sustava regulacije turbina na HE Gojak ugrađen je novi, digitalni sustav turbinske regulacije. Sustav turbinske regulacije ukljucuje na kvarove tolerantni digitalni turbinski regulator, pomocni turbinski regulator s automatskim prebacivanjem u radu, hidraulicni agregat, hidraulicne servomotore, upravljanje regulatorom tlaka, sustav za trajni nadzor turbine (stalno pracenje kompletnog vibracijskog stanja turbine), mjerenje protoka vode u cjevovodu (posredno mjerenjem diferencijalnog tlaka metodom Winter-Kennedy), podrazvod izmjenicnog i istosmjernog napajanja, te kompenzatorski nacin rada sustava turinske regulacije u prijelaznim režimima rada.

Lisce, sitno granje od okolnog raslinja, samoniklo vodeno raslinje i ostale necistoce koje se mogu naci u dovodnom kanalu prije tlacnog cjevovoda potrebno je rucno uklanjati s ulazne resetke nekoliko puta na dan kako bi hidroelektrana mogla nesmetano raditi. U radu je prikazana automatska cistilica na HE Zavrelje kao i njezin nacin upravljanja. U tehnickom opisu dan je uvid u pogonski dio cistilice i upravljacki dio te je opisan nacin izrade 3D konstrukcije automatske cistilice.

Opisana su mjerenja oscilacija razine vode izvedena u vodnoj komori i odvodnom tunelu na HE Dubrovnik. Snimljen je odziv sustava u vodnoj komori u situaciji ispada elektrane iz EES-a, radi analize rada pogona u istim uvjetima, ali za povecan instalirani protok. Odziv u odvodnom tunelu snimljen je kako bi se ispitala mogucnost preljeva vode iz tunela za ekstremne pogonske uvjete. Koristene su ultrazvucne sonde za mjerenje udaljenosti, spojene na osobno racunalo preko programabilnog kontrolera. Mjerene razine vode citaju se i spremaju u digitalnom obliku u stvarnom vremenu. Priloženi su odzivi sustava na obje lokacije.

It is well known that water balance of one area means mutual relationship between rainfall quantity, sum of runoff quantities (surface and subsurface runoff) and evapotranspiration quantity during specific time. Usually, catchment area is what we use for our analysis. In the case of Nature Park Velebit that is not possible because terrain comprises of many catchment areas (boundaries are defined in 1981) and covers area of Lika region, Podvelebit region and part of Zrmanja catchment area. Aditional complexity arises because of fact that the park area is one extremely karstic area with significant topographic and climatic distinctions. Particularly, due to elevation in parts of the Park with higher altitude, surface runoff is increasing and sinking is decreasing. Also, evapotranspiration is decreasing due to lower air temperatures at higher altitudes. In addition, climatic characteristics inside the Park are changing from mediterranean to continental-mountainous. Nature Park Velebit covers area of 2247 km2 and encompasses almost all Velebit – the most significant Croatian mountain based to its relief, geology, hydrogeology, hydrology, speleology and vegetation. Although entire Velebit presents exceptional nature resource value, two areas inside its territory are especially highlighted because of their characteristics. Those are National Park « ; North Velebit» ; and National Park « ; Paklenica» ; . Nature Park Velebit area is one of the areas in Croatia with highest rainfall quantity. However, owing to litological structure and complex tectonical relationships, there is still shortage of large perennial streams. The fact is that waters originating in the north-northwest side of Velebit often sink after short surface flow and then discharge in the Adriatic Sea. Precipitation waters from west-southwest sides of Velebit become torrential intermittent streams which are quickly draining into Adriatic Sea. Smaller part of those waters is infiltrating into karstic underground and like waters from the north and north-east side of Velebit, are becoming coastal springs and/or vruljas, or discharge difusely into sea. It's estimated that 2.5 billion m3 of water from area of Nature Park Velebit discharge uncontrollable into the sea. Those are huge quantities of water which are unfortunately seasonaly very unevenly distributed, but they can also have great importance for water management of Croatia.

During the recent 4th European Summer School in Clinical Pharmacology and Therapeutics in Vrsac (2006, September 16–20), organized by the European Association of Clinical Pharmacology and Therapeutics (EACPT) and the Clinical Pharmacology Section (CPS) of the Serbian Pharmacological Society (SPS), as well as the International Federation of Associations of Pharmaceutical Physicians and the Serbian Association of Pharmaceutical Physicians it was obvious that the status of clinical pharmacology still varies widely from country to country in Europe 1, . Namely, in spite of many initiatives, its development in many countries is too slow. The aim of this review was to present the development and the state of the art of clinical pharmacology in Serbia.
