AB  - In this paper 1D crystal lattice is analyzed within harmonic approximation, with one atom per elementary cell and nearest neighbor interaction included. For this type of crystal lattice dispersion relations are well known. Thermodynamic functions (specific heat and phonon thermal conductivity) are calculated via phonon density of states given in exact form. Thermodynamic variables are calculated for a whole temperature range. In limiting cases of low and high temperatures these thermodynamic variables can be found in analytic forms. For thermal conductivity the results of Callaway model for exact phonon density of states are compared with the results of Callaway model for Debye approximation of phonon density of states.

AB  - Outbreaks of infectious diseases are one of the worst scourges in the history of mankind that have affected its flow. First they were tied to the supernatural beings, then they were used as a cause for wars and state internal showdowns, only then as a matter of medicine. For a long time, epidemics of infectious diseases have been considered only as a medical phenomenon, but by expanding the fields of security procedures, this phenomenon is classified in a group of emergency. It was found that in these situations there is certain mathematical regularity that can predict possible consequences. In order to be mathematically modeled performance of the epidemic in a large population need to be grouped into departments. Agreed standard labels for these units as S (for susceptible - exposed), I (infected) and R (recovered), so this model is called the SIR model. This is a simple model for many infectious diseases including measles, mumps and rubella. Number of persons in each department may vary in time, and it follows that the precise numbers must be calculated as a function of time t: S (t), I (t) and R (t).
AB  - Mnogi izazovi, rizici i pretnje bezbednosti se u savremenoj istoriji multiplikuju i time se njihov broj neumitno povećava. Jedno od takvih bezbednosnih pitanja je epidemija infektivnih bolesti, za koje se sedamdesetih godina prošlog veka smatralo da su kao javnozdravstveni problem prevaziđene, te je od strane prevashodno Svetske zdravstvene organizacije trijumfalno potvrđeno da je imunizacija uspela da nadiđe tu pošast zauvek. Problemi su tek predstojali, jer su patogeni vremenom uspeli da postanu rezistentni na postojeće medicinske tretmane. Postalo je značajno kako pristupiti problemu na nov način. Jedan od načina koji u velikoj meri mogu učestvovati u suzbijanju zaraznih bolesti jeste matematičko modelovanje epidemije. Na osnovu epidemija koje su se dogodile, mogu se izraditi modeli mogućih epidemija na bilo kojoj teritoriji, te se, stoga, mogu ublažiti njihove posledice. Zamena proučavanog objekta njegovim likom - matematičkim modelom i njegovim izučavanjem - jeste bit matematičkog modelovanja. Doduše, moramo se voditi svešću da ti modeli imaju mnogo nedostataka, kao u slučaju epidemije zaraznih bolesti, kada se moraju uzeti u obzir odnosi u društvu, što nije moguće obuhvatiti širokom skalom dinamike širenja infekcije. Matematički SIR model je prvi sačinjen od strane Kermaka i Mekendrika i odigrao je ključnu ulogu u matematičkoj epidemiologiji. U modelu je posmatrana populacija podeljena na tri grupe: osetljive S, inficirane I, i oporavljene R i te grupe se menjaju tokom vremena tj. funkcije su od t - S(t), I(t) i R(t). Osetljivi su oni koji nisu inficirani ni imuni, inficirani su oni koji su inficirani i mogu preneti bolest, a oporavljeni su oni koji su inficirani, oporavili su se i konstantno su imuni. Ispitivanjem epidemije enterokolitisa koja se pojavila u Topoli kod Kragujevca 2002. godine, došlo se do zaključka da je srž modelovanja epidemija zaraznih bolesti pronalaženje odnosa između parametara infekcije i da oni služe za proračune o delotvornom programu masovne vakcinacije u cilju sprečavanja ekspanzije epidemija.

AB  - In the nanocylinder, a cut-off from the molecular crystal, dielectric permeability tensor is investigated. Excitons in the nanocylinder arise due to the exciting of the electron subsystem of the molecule. In evaluation of dielectric permeability Dzhyaloshinskii-Pitaevskii approach is used, connected with retarded and advanced exciton Green's functions and correct use of Paulion Green's function. It turned out that refraction and absorption indices depend on configuration coordinates, having maximal values at boundary cross-sections and minimal value at central cross-section of the nanocylinder broken symmetry structure. Although it was expected that boundary conditions make higher refractive and absorptive characteristics of the nanocylinder, this appeared not to be possible because Paulion Green's function is not proportional to the exciton concentration.

Reallocation of electoral votes is estimated on the basis of analogy of the electoral process and absorption of gases. According to the analysis conducted here, one could say that this idea has a good perspective.
AB  - Ranijih godina je bilo pokušaja da se prenesu ideje i metodi iz jedne oblasti delatnosti u drugu, radi boljeg razumevanja kompleksnih fenomena i procesa što je doprinelo usavršavanju i jedne i druge delatnosti. Posebno je matematičko modelovanje prodrlo u ne samo u druge oblasti nauke, veći i gotovo u sve oblasti života i rada. Teško je zamisliti savremenu nauku i savremeni život bez široke primene matematičkog modeliranja. Zamena proučavanog projekta njegovim likom - matematičkim modelom i njegovom analizom i proučavanjem je suština metodologije matematičkog modelovanja. Takodje, treba istaći postojanje tendencije da se društvena kretanja analiziraju, a njihova kretanja predviđaju, na bazi standardnih stohastičkih fizičkih zakonitosti uz primenu teorije fluktuacija. Ove analogije su nesumnjivo korisne i mogu da ubrzaju razvoj drugih nauka, ali naravno, uz jedno ograničenje: treba tačno utvrditi do koje se granice mogu i smeju korisititi analogijie: svako prekoračenje ovih granica moglo bi da dovede do krupnih zabluda (H. Haken, 1977). U radu su opisani procesi ireverzibilne i reverzibilne apsorpcije gasnih molekula. Treba napomenuti da je ireverzibilna apsorpcija davno uvedena u gasne i termodinamičke teorije. Što se tiče reverzibilnih apsorpcija, njena istraživanja su novijeg datuma i inicirana su činjenicom da se kvaziperiodično ponašanje temperature i pritiska nije moglo objasniti preko ireverzibilne apsorpcije. U slučaju izbornog procesa kada imamo samo dva kandidata preraspodela izbornih glasova procenjena je na osnovu analogije izbornog postupka i apsorpcije gasova. Čvrsto opredeljeni glasači imaju tok glasova kao molekuli koji se ireverzibilno apsorbuju, dok su neopredeljeni glasovi glasača analog molekulima koji se reverzibilno apsorbuju. Ovo je jedan od prvih pokušaja da se fizičke zakonitosti koriste u socijalnim problemima. Prema analizama koje su ovde izvršene, moglo bi se reći da ova ideja ima dobru perspektivu.

AB  - Spectra of possible phonon states, as well as thermodynamic characteristics of nanocrystals (ultrathin film and quantum wire) of simple cubic crystalline structure are analyzed in this paper, using the method of two-time dependent Green functions. From energy spectra and internal energy of the system the thermal capacitance of these structures in low temperature region is found. The temperature behavior of specific heat is compared to that of corresponding bulk structure. It is shown that at extremely low temperatures thermal capacitance of quantum wire is considerably lower than the thermal capacitance 4 film as well as the bulk sample. Consequences of this fact are discussed in detail and its influence to thermodynamic properties of materials is estimated.

AB  - The superconductivity properties of cylinder with nano cross-section are investigated. In the nearest neighbours approximation, electron Hamiltonian of cylinder decays onto two independent Hamiltonians. One corresponds to electrons which propagate along chains parallel to the axis of cylinder. Second correspond to electrons moving in discs. The electron-phonon interaction Hamiltonians are found and superconductive properties were examined in the frames of BCS approach. It was shown that superconductive temperature in chains is several Kelvins, while in discs it can be higher for two orders of magnitude. It is also shown that magnetic field produced by electron currents in discs is of the order of thousand Tesla, i.e., extremely high.
