Emberbőr
Domonkos István vajdasági magyar költĹ‘ verse a szĂ©tszĂłrĂłdásrĂłl, idegenbe szakadásrĂłl szĂłl, amit a nyelv darabokra törĂ©sĂ©vel Ă©rzĂ©keltet. Ahogy megszĂłlalunk idegenben idegenĂĽl, fĹ‘nĂ©vi igeneveket halmozva, Ăşgy torzulhat az anyanyelv az idegen közegben. A vers „emberbĹ‘r kötĂ©s” hasonlata visszautal magára az emberre Ă©s a helyzet morbid brutalitására. IdegenkedĂ©st Ă©s taszĂtĂł Ă©rzĂ©st vált ki az emberbĹ‘rbe kötött könyv kĂ©pzete, nem fĂ©r össze a könyvrĹ‘l mint a kultĂşra kĂ©pviselĹ‘jĂ©rĹ‘l alkotott toposszal, pedig a tárgy valĂłs
Hierarchikus markov folyamatok alkalmazás a a sertéstartás döntési folyamataiban
Jelen tanulmányban a Markov láncokon alapulĂł Markov döntĂ©si folyamatokat tárgyaljuk, valamint ezek továbbfejlesztett változatát, a Hierarchikus Markov Folyamatokat. RĂ©szletesen leĂrjuk ezen folyamatok optimalizáciĂłs lehet?sĂ©geit. IsmertetĂĽnk továbbá egy dán kutatĂłk által állattenyĂ©sztĂ©si döntĂ©sek támogatására kifejlesztett, e folyamatokon alapulĂł Ă©s szabadon letölthet? programot. A program számos lehet?sĂ©gĂ©b?l a kocanevelĂ©s Ă©s vemhesĂtĂ©s modell használatát mutatjuk be. Megadjuk a program futtatásához szĂĽksĂ©ges alapparamĂ©tereket, beállĂtásokat, valamint egy modellezett állattartĂł telep kocáira Ă©rtĂ©k iteráciĂłval számĂtjuk az elĂ©rhet? jövedelmet Ă©s a kocánkĂ©nti döntĂ©sek sorozatát. Bemutatjuk az állat termelĂ©sben tartására, illetve a koca termĂ©kenyĂtĂ©si számára hozott döntĂ©sek eredmĂ©nyĂ©t. PĂ©ldán mutatjuk be továbbá az ilyen döntĂ©sekhez kapcsolt relatĂv hasznosság alakulását.</jats:p
Megmaradási Ă©s informáciĂłs folyamat modellek közvetlen számĂtĂłgĂ©pi lekĂ©pezĂ©se = Structural Model Based Direct Computer Mapping of Conservational and Informational Processes
ElkĂ©szĂtettĂĽk a strukturális modellek közvetlen számĂtĂłgĂ©pi lekĂ©pezĂ©sĂ©n alapulĂł mĂłdszer formális leĂrását, az un. generikus kĂ©trĂ©tegű hálĂł modellt. A modell struktĂşráját tekintve kĂ©tfĂ©le csomĂłpont Ă©s kĂ©tfĂ©le kapcsolat tetszĹ‘leges tĂ©r- Ă©s tulajdonságkoordináták mentĂ©n multiplikálhatĂł, idĹ‘ben változĂł hálĂłja. A kĂ©tfĂ©le csomĂłponthoz kĂ©tfĂ©le funkcionalitás rendelhetĹ‘, amelyek a szoftver implementáciĂłnál kisebb programrĂ©szletek lehetnek. A hálĂł generálja az Ăşn. hatás-utak hálĂłzat struktĂşráját. MĂ©rleges folyamatokra a hálĂł generálja az Ăşn. mĂ©rleg-utak hálĂłzatát. Az általános folyamat modellt egy több szempontĂş diszkrĂ©t/folytonos genetikus algoritmussal összekapcsolva mĂłdszert alakĂtottunk ki a metabolikus folyamatok rĂ©szletes dinamikus modelljĂ©nek identifikálására. A szakirodalombĂłl vett pĂ©ldák Ă©s becsĂĽlt paramĂ©terek ismeretĂ©ben bemutattuk, hogy elvi lehetĹ‘sĂ©g van a rĂ©szletes (minden enzimet, illetve enzim komplexet Ă©s elemi lĂ©pĂ©st leĂrĂł) sejtbiolĂłgiai modellek szimuláciĂłjára. A megoldás hibrid modell esetĂ©n is alkalmazhatĂł. Az informáciĂłs folyamatokat a megmaradási folyamatok egy speciális rĂ©szekĂ©nt Ă©rtelmeztĂĽk. A modellt kĂ©t mĂ©rtĂ©kkel kiegĂ©szĂtve lokális gazdasági potenciál számĂtásán alapulĂł szuboptimális döntĂ©seket alkalmaztunk a supply/demand chain tĂpusĂş korlátozottan nyitott folyamatok tervezĂ©sĂ©re. A modell szoftver implementáciĂłjának adekvát megvalĂłsĂtására kidolgoztuk a modellel izomorf hardver architektĂşra megvalĂłsĂtásának alapelveit. | Generic bi-layered net model, as formal description of direct computer mapping of process models, was developed. The optionally time-varied structure of net consists of two kinds of nodes and edges that can be multiplied along the spatial and property coordinates for distributed parameters. The two kinds of nodes can be associated with various functionalities, that are described by brief programs in the software implementation. The net generates the network structures of the influence routes. For balance processes the net generates the network of flux routes. Combining the process model with a multiobjective discrete/continuous genetic algorithm a method was developed for the identification of the detailed dynamic model of metabolic processes. Using example from the literature and estimated parameters, we showed, that it is possible to simulate the most detailed metabolic models, containing all of the enzymes, enzyme complexes, and elementary steps. The method can also be applied for hybrid models. The informational processes were interpreted as a special part of the balance (conservational) processes. The new process model, supplemented by two measures, made possible to apply economical potential based local suboptimal cooperative decisions in the synthesis of almost closed supply/demand chains. For the adequate computer implementation of the generic bi-layered net model, the principles of isomorphic hardware architecture were proposed

A CONTRIBUTION TO THE DETERMINATION OF 2-[2-(CHLOROPHENYL)-2-PHENYLACETYL]-1,3-INDANEDIONE (CHLOROPHACINONE)
Preparation of a dynamic simulation model to support decision making in a sensitive rural area
This paper focuses on the demonstration of a conceptual framework and a dynamic simulation based tool, through the example of southern catchment basin of Lake Balaton. The objective is to support the sustainable and reasonable environmental management by model based investigation of various scenarios.
In the developed hydrological model, the coherence is given by the compartmentalized dynamic network of water flows and water bodies. The completeness is solved by the complete and disjoint covering of the whole area by modeled patches, corresponding to the CORINE land cover database of natural and human built environment. The complexity of the large scale and long term processes is managed by evaluating detailed models only for one representative patch from each class, while the calculation of the similar patches is solved by simple multiplication rules. According to the first experiences, the developed framework is able to integrate the field experts’ knowledge (data, relations, empirical knowledge, etc.) for the prediction of land use effects besides different climatic scenarios. It is noted, that continuous extension and refinement of the model and of the involved data is necessary, especially through more realistic case studies.</jats:p
