U radu se analizira prikaz Menelaja u šest tragedija, a to su: Sofoklov Ajant i Euripidove Ifigenija u Aulidi, Trojanke, Orest, Helena i Andromaha. Osim toga, uzete su u obzir i tragedije u kojima se spominje ili se na njega aludira: Eshilov Agamemnon, Sofoklov Filoktet te Euripidove Elektra, Ifigenija u Tauridi i Rez. Analizira se karakterizacija Menelajeva lika te se izdvajaju sličnosti i razlike u njegovu prikazu. Analiza je provedena na dvije razine: uspoređen je prikaz Menelaja unutar opusa svakog od trojice dramatičara pojedinačno, a naknadno je provedena i usporedba prikaza među autorima. Ponuđena su i objašnjenja za pojedine uočene varijacije koje mogu proizlaziti iz fabule ili su rezultat odnosa među likovima ili ovise o njihovim karakterima i sl. The paper presents Menelaus as a character in six tragedies, namely: Sophocles᾽ Ajax and Euripides᾽ Iphigenia in Aulis, Trojan Women, Orestes, Helen and Andromache. In addition, the tragedies in which he is mentioned or alluded to are analyzed: Aeschylus᾽ Agamemnon, Sophocles᾽ Philoctetes and Euripides᾽ Electra, Iphigenia in Tauris and Rhesus. The characterization of Menelaus is analyzed and the similarities and differences in his depiction are singled out. The analysis was conducted on two levels: the presentation of Menelaus within the opus of each of the three playwrights was compared individually, and a comparison of the presentation among the authors was subsequently conducted. Also, explanations for certain observed variations are offered that may arise from the plot or that are the result of relationships between characters or depend on their characters, etc.

Pavement surface deflection measurements are usually conducted with different nondestructive testing methods. One of the most commonly used method is Falling Weight Deflectometer test (FWD), where an impulsive load is applied on pavement surface and the deflections are measured at a number of points radially distributed from the centre of falling weight. All the testing parameters are adjusted to correspond to the effect of loading due to standard axle on the investigated road. Laboratory for Transportation Engineering from Faculty of Civil Engineering Universi-ty of Rijeka in cooperation with Croatian Civil Engineering Institute (IGH) measured pavement deflections on the second longest and one of the most loaded Croatian highways A3 Bregana – Zagreb – Lipovac (E 70). This highwayis characteristic for a greater amount of heavy vehicle traffic whichis approximately 20% of total AADT and some highway sections were built 30 years ago, which were the reasons for the investigation of road’s structural capacity. In this paper part of the data collected with FWD test on one road section for both highway lanes will be presented. The aim is to interpret collected data for driving and passing lane for one highway section in Croatia.

Sight distance (horizontal, vertical) is one of the key factors in ensuring traffic safety at the level intersections and access points. Despite the relatively clearly defined demands in the legislation (eg. Act about public roads), where are defined responsibilities - both road owners and land owners in ensuring sight distances - in the everyday practice in this field situation is very different. Often - especially within/inside urban areas - inadequate sight distances "solve" with just a road mirrors, which often is not enough (or good solution). The purpose of this paper is to make a comparison of different standards/guidelines/ policies that define the scope of the sight distances on the level crossings/access points, carry out an analysis of sight distances and perform the analysis of sight distances according to real motor vehicle speeds. The aim of this paper is to examine the adequacy of existing calculations stand-ards in the level crossings and access points and define differences between calculations - ac- cording different standards/regulations. (PDF) Sight distance at level crossings and access points: influence of real measured values (input data) to the sight distance calculation.

Maneuvering distance and stopping sight distance are important traffic safety elements at an at-grade intersection. Croatian official standard for sight distance calculation (HRN.U.C4.050) dates from 1990. This regulation treats sight distance values in a very simplified way. The mentioned regulation seems to be outdated since various researches of real traffic conditions at an at-grade intersection have been conducted to detect significant factors influencing sight distance. In this paper an overview of sight distance calculation methods according to Croatian official standard (HRN.U.C4.050), and additionally according to Croatian guidelines for urban intersection design from the traffic safety aspect (Hrvatske ceste, 2004.), American guidelines for geometric design of highways and streets – The Greenbook (AASHTO, 2001.) and PIARC Road Safety Manual (2003.) is done. These calculation methods were applied at an at-grade intersection in City of Rijeka, where necessary calculation parameters (vehicle speed, friction coefficient) were collected at the site. This intersection is distinctive for greater amount of traffic accidents due to lack of maneuvering and stopping sight distance. The conducted analysis of different sight distance calculation methods shows that inspected calculation methods differ for calculation parameters and consequently given sight distance values. The sight distances obtained with suggested calculations from Croatian standard are in all cases less conservative than the sight distances calculated with other, more detailed methods. This is why a revision of current Croatian regulations concerning sight distance is suggested.

Since the liberalization and unbundling of power systems, power market simulators and agent-based simulation are gaining popularity. Power Trading Agent Competition (Power TAC) is a recent power market simulator that provides an opportunity to test market designs for smart grids. This paper describes the CrocodileAgent 2012 which is an attempt to build an efficient agent in the Power TAC competition. We demonstrate the interactions of modules within the agent and typical forecasting process that the CrocodileAgent 2012 performs for its needs. In the follow-up of those results, we describe two approaches that Agent 2012 used to exploit the drawbacks in the current market design: infinite periodic payment and PAC- MAN syndrome. Based on those, we propose more rounds in each competition cycle with an aim to increase the learning curve of Power TAC competitions and improve the speed of contribution to the society.

For resolution of overlapping signals there are methods based on purely mathematical curve resolution techniques using logarithmic, Fourier or derivative transformations, the last one being improved using measurement at selected “zero-crossings” of derivative, mainly spectrophotometric, signals. For signals and systems where conventional resolution techniques are not very suitable, multivariate calibrations using a family of factor analysis techniques can be used as general selectivity and reliability enhancement tools. In this work a simple method based on signals ratio resolution (SRS) has been fully investigated and some new criteria are established, which enable the determination of two components in mixture from one set of the experimental data. The procedure consists of using several different resolving functions and plotting the difference of the mean of absolute and nonabsolute values of pseudosignals [PDMMV(PS) against analyte concentration obtained with each of the resolving functions, thus obtaining 2 straight lines having intersections that give a concentration of individual dye in binary mixture. The results obtained with SRS method were compared with Vierordt’s method in which absorbances of the mixed sample solutions were measured and then the concentration of each compound was calculated from the following simultaneous equations: A1 = 1 c1 + 1 c2 A2 = 2 c1 + 2 c2 where c1 and c2 are the concentrations of two dyes, A denotes the absorbance of the mixture solution, and  and  represent the values of A (1%, 1 cm) for individual dye. The assay precision of this method depends on the selection of wavelengths (). A number of criteria can be used to select  and to decrease estimation errors for components in mixtures with both low and high contents. A first-derivative spectrophotometric method using a zero-crossing technique of measurement for simultaneous determination of binary dye mixture was used, too. The increased selectivity in derivative spectrophotometry results because bands that are overlapped in zero-order absorption spectra can be separated in the derivative mode. Mean recoveries, relative standard deviations and linearity ranges in calibration graphs of the methods are compared and discussed.

Antropološka analize kranijalnih ostataka pokazala je da se materijal iz Bezdanjače sastoji od 20 muških (4 juvenilne, 16 adultnih), 9 ženskih (3 juvenilne, 6 adultnih) i 13 dječjih osoba (do 18 godina, neodređenog spola), te 2 adultne osobe neodređenog spola. Analiza dentalne patologije, higijene i abrazije upućuje na to da su se individue uzorka vjerojatno hranile zrnatom, žitnom hranom mljevenom mlinskim kamenom kao i mliječnim proizvodima domesticiranih životinja čije su kosti također pronađene u spilji. Poredbena odontometrijska i morfološka analiza preostalih zubi dala je kontradiktorne rezultate, s jedne strane recentna populacija pokazala je morfološku dentalnu simplifikaciju sa smanjenjem broja kvržica, a s druge strane povećanje veličine zuba. Razlog može biti u ne-reprezentativnom uzorku zbog dugog perioda ukapanja, odnosno veće abrazije pojedinih zubi materijala iz Bezdanjače.

U ovom magistarskom radu obrađen je kranijalni materijal ljudskih skeletnih ostataka otkrivenih u spilji Bezdanjači 1960. godine. Prema materijalnoj kulturi pronađenoj uz skelete zaključeno je da se radi o nekropoli iz srednjeg i kasnog brončanog doba, što je potvrdila radio-karbonska datacija. Period ukapanja u ovoj nekropoli trajao je od 1500 do 600 godine pr. Krista.Cilj rada bio je odrediti spol i dob individua dento-antropološkom analizom lubanja i čeljusti. Nadalje komparacijom dentalnih fizioloških i patoloških nalaza sa do sada poznatim arheološkim i paleontološkim nalazima, nastojalo se utvrditi vrstu, način prehrane i stil života individua iz uzorka.

The problem of vibrations on pedestrian bridges is a topic that has been intensively explored over the past 20 years. Although an incredibly large amount of research has emerged on the topic [1], the problem of vibrations is very poorly represented in European standards. Annex B to Eurocode EN 1995-2:2013: Design of timber structures [2] gives expressions to determine the vertical acceleration of the timber bridges with simply supported beams or truss systems, depending on the natural frequency of the bridge, the number of pedestrians crossing the bridge and the way they move across the bridge (walking or running). UK National Annex to Eurocode EN 1991-2:2003: Actions on structures [3] gives models of pedestrian loads, using which is possible to calculate the vertical acceleration of the bridge, also depending on its natural frequency, the number of pedestrians and the way they move across the bridge. In this paper, the calculations of maximum vertical acceleration on two fictional pedestrian bridges will be made according to these two different European standards. The results of the calculations will be presented and compared.

Today, oil drilling is mainly done in deep waters far from the coastal area. In addition, for purpose of easier maintenance and transportation, drilling rigs usually float on water. However, transport vessels cannot be anchored under such conditions, so they need a dynamic positioning technique to keep the stationary position relative to a reference point on the sea surface. Dynamic positioning systems provide the ability to control ship position and direction using a combination of thruster mechanism and propulsion, measurements of essential vessel variables, as well as the surrounding impacts, such as wind speed. The required criteria for performing a given task, as well as the surrounding conditions and expectations of behaviors at different natural phenomena, together have an impact on designing dynamic positioning systems. Accuracy of the observed dynamic positioning system depends on the selected wave filtering method and controller design. In order to reduce the amount of thruster oscillations, it is necessary to filter noisy signal measurements in terms of their reconstruction and subsequent use for the purpose of control. Some advanced filtering techniques utilize the Kalman recursive filter, which provides optimum estimated values from the noisy measurements by minimizing the error variation for linear and nonlinear signals. Another approach to noise removal is based on time-frequency distributions. For this purpose, high-resolution, reduced interferences time-frequency distributions should be developed and used. Adaptive, datadriven filtering in the time-frequency domain may be used to enhance accuracy of the positioning systems and mathematical models of the vessel, as well as the characteristics of the waves that appear to be a disturbance when performing a task on water.

The aim of this paper is to examine the effect of solar collectors’ area, domestic hot water (DHW) storage volume and DHW consumption on the work performance of DHW system powered by solar energy. All of the considered systems incorporate flat plate solar collectors with biaxial solar tracking, DHW storage tank, circulation pump and system controller. The values of studied parameters for different cases were generated with the orthogonal array design of experiments whereupon the simulations of different DHW systems were performed in TRNSYS software. Simulation results were used for response surface optimization [1] with the aim to maximize solar gains during winter but maintain water temperatures in system below 95 °C during summer. The three-variable regression function which describes the effect of storage tank volume, DHW consumption and solar collectors’ area on the maximum useful solar energy gain to energy provided by auxiliary heater ratio is obtained. Results of the optimization are optimal storage tank volume, DHW consumption and solar collectors’ area with respect to the maximum useful solar energy gain to energy provided by auxiliary heater ratio.

In this paper, optimization of a small size water-water shell and tube heat exchanger has been performed after a series of numerical calculations. Firstly, a mathematical model was defined, consisting of computational domain, conservation equations and boundary conditions. The problem was considered as steady-state, laminar and incompressible. Numerical method was the finite volume method, SIMPLE algorithm was used for pressure-velocity coupling and ANSYS Fluent was used as numerical solver. The numerical procedure was previously validated using experimental data. In order to perform optimization, a number of numerical calculations hasbeen performed for three different parameters ; tube diameter, shell diameter and shell-side inlet velocity. Specified objective functions were maximum heat flux, minimum mass and combined function of maximum heat flux with minimum mass. Using response surface methodology and Box-Behnken design, optimal values of parameters can be visually determined from plotted 3D surface plots.

In the electroencephalography (EEG) data signal processing [1], commonly used methods utilize time and frequency domain analysis. Analysis in time domain gives an amplitude value of the signal in each time moment. As opposed to that, analysis in frequency domain indicates which frequencies are present in the signal. Furthermore, lack of frequency-information in the time domain analysis and lack of time-information in frequency domain analysis in nonstationary signals where frequency content varies with time leads to a usage of joint time-frequency representation (TFR)[2]. Such representation, which is localized in both time and frequency, is obtained using a distribution whose domain is the two-dimensional (t, f) space called time-frequency distribution (TFD). Apart of the most commonly used TFD - Wigner-Ville distribution (WVD), in this paper EEG signal is presented and compared with several different TFDs. Additionally, some differences between different types of analyses, such as empirical mode decomposition, wavelet etc., are explained.

The objective of the present numerical study is to investigate the air side thermal-hydraulic characteristics for water-to-air heat exchanger. For the purpose of numerical analysis, 3D mathematical model is developed and implemented, using governing equations of fluid flow and heat transfer, and boundary conditions. The fluid is considered incompressible with constant properties and the flow is assumed to be steady-state and laminar. All the computational work is carried out using the finite volume method by means of CFD software ANSYS FLUENT 18.2. The coupling between velocity and pressure is performed with the SIMPLE algorithm and the Power Law scheme is used for the treatment of convection- diffusion terms. Numerical mesh is validated by performing a grid independence study. A comparison of the numerical results with obtained experimental data shows good agreement. Numerical simulations have been performed for Reynolds number in a range 285 < Re < 690, with corresponding frontal air velocity ranging from 0.825 to 2 m/s. Inlet air and water temperatures are 288.7 K and 323 K, respectively. Numerically obtained temperature contours and velocity vectors in the mid-plane between two fins and near the fin surface have been presented. Finally, dependence of average air-side Nusselt number on Reynolds number has been analysed.
