Targeting Alien Filmmakers in 1930s Hollywood
Authors: Winn J. Emmett
Published: August 2019

TARGETING ALIEN FILMMAKERS IN 1930s HOLLYWOOD On January 28, 1933, the US government made its first strike in a much heralded drive to rid Hollywood of alien filmmakers. A special assistant to Secretary of Labour William Doak forecast "a wholesale exodus of foreign film talent" would begin.(1) The news made front-page headlines across the country as government agents interrogated Australian-born screenwriter John Farrow and other Hollywood filmmakers.(2) Labour Department special agents and local police arrested Farrow as he danced with South American actress Mona Maris at a fashionable Los Angeles hotel.(3) His crime, according to the immigration special agents, was that he overstayed his legal visitor permit. This study investigates the government's campaign against alien filmmakers in the early 1930s and finds that government promises to deport hordes of foreign workers were never serious, but were instead a project intended for publicity, both to show Americans...
The Language and Genealogy of Early Spy Cinema
Authors: Boron Lukasz
Published: August 2019

THE LANGUAGE AND GENEALOGY OF EARLY SPY CINEMA: 1919-1959 AbstractThe following paper is a genre-specific study of early spy cinema that traces the language and genealogy of the genre from its conception to its modernity, in the films of Hitchcock, Reed, Wilder, Huston, and Fuller. Focusing on American and German film tradition, this paper examines espionage cinema from 1919-1959. The origins of the hero are briefly examined through a historical framework that traces his lineage and literary sources of influence to: epic poetry and Byronism, mythology, folklore, legend, oral tradition and early espionage literature. The impetus of this study is the representational and ideological analysis of several recurring motifs - or signifiers - within the spy genre, namely: (a) the domesticated spy-agent, (b) the active investigator and passive detective as spy, (c) the fugitive spy, or agent in flight, (d) the double agent or domestic informer, and (e)...

THE NEW VICISSITUDES OF AUTEUR CINEMA: KARLOVY VARY 2010 The Festival and its Ambiance     The Karlovy Vary Film Festival is a place where everyone feels at home - from the brightest stars of world cinema and Hollywood staying at Grand Hotel Pupp, to the student back-packers, who arrive in numbers every year and, in anticipation of some last minute ticket availability, squat in the hallways of Hotel Thermal, housing the festival headquarters as well as five festival film theatres. This unassuming hospitality was elegantly emphasized in the festival film vignettes, shown before each screening. Witty animation tributes to the festival president Jií Bartoška and its artistic director Eva Zaoralová, inspired by the Pink Panther and Iakov Protazanov's Aelita respectively, were paired with a series of black-and-white shorts, starring some of the most illustrious recipients of the festival's Life-Time Achievement Award, the Crystal Globe, and featuring the statuette's mostly...
Filmic Space and Real Time in Hitchcock’s Rope
Authors: Dellolio Peter J.
Published: August 2019

FILMIC SPACE AND REAL TIME IN HITCHCOCK'S ROPE "Brandon, how did you feel?""When?""During it?"Philip Morgan to Brandon Shaw IntroductionRope explores some of the fundamental characteristics of the cinematic abstraction of time and space by using the mobile camera as an agent that gives plastic reality to subjective material. In Rope, a synthesis of real time and filmic space forces the viewer to absorb narrative information on multiple, often distastefully ironic levels. At the same time, the viewer is given freedom of selection in terms of how, when, and why his/her attention is split, inviting some comparison with similar choices experienced during depth of focus shots, a spatial configuration that Hitchcock characteristically avoided. The movement of the camera throughout the film places the viewer in the ethically, emotionally, and psychologically uncomfortable position of perceiving perversity in the relationship between image and dialogue. For example, during the...
Moral Luck in the Films of Woody Allen

Published: August 2019

MORAL LUCK IN THE FILMS OF WOODY ALLEN We happened to have won the war. But if we didn't win the war, then history would be created differently.(Judah's aunt in Crimes and Misdemeanors) The purpose of this essay is to discuss how moral issues are represented in two films of Woody Allen: Crimes and Misdemeanors (1989) and Match Point (2005). My principal tool of analysis is the concept of 'moral luck', elaborated in an essay of the same title by Bernard Williams (1929-2003) (see Williams 1981a), widely cited as the most important British moral philosopher of his time. I am using this concept because these two Allen films can serve as a perfect illustration of its validity or, conversely, because the idea of moral luck supports the way the director deploys moral problems in his films. My discussion will consist of three parts. In the...
On Lars von Trier, Enfant Terrible of Danish Art Film
Authors: Hjort Mette
Published: August 2019

THE PROBLEM WITH PROVOCATION: ON LARS VON TRIER, ENFANT TERRIBLE OF DANISH ART FILM Anyone interested in contemporary art is likely to have spent a good deal of time pondering the nature and role of artistic provocation. Provocation as a crucial feature of artistic practice was largely unknown before 1800 (Walker 1999: 1). The idea of 'shocking the recipient' was, however, 'a dominant principle of artistic intent' for members of the various avant-garde movements that emerged in the early decades of the 20th century (Peter Bürger, cited in Walker: 2), and at this point the provocateur is a well-known and even expected figure in the landscape of art. It is not difficult to think of examples of artworks that are self-evidently about creating a sense of outrage. Let me mention just a few well-known works that prompted a public outcry: Rick Gibson's Human Earrings (1985), which consists of a...
Remarks on the Actual Status of Romanian Cinema

ROMANIA ON THE MOVIE MAP: REMARKS ON THE ACTUAL STATUS OF ROMANIAN CINEMA This was my second trip to Romania after more than 20 years, and I was grateful to enjoy the beautiful city of Cluj, the people, the relaxed atmosphere. And certainly the considerate organizers of the festival and its young volunteers! But the most rewarding experience of my trip was watching Romanian films 'on site' - that is, in their own context, in the close proximity of filmmakers, film stars, film critics and of Romanian viewers. The round table discussion, hosted by the Romanian Film Critics' association and helmed by Dana Duma, Magda Mihailescu and Mihai Chirilov (artistic director of the Toronto International Film Festival), is yet another congruous - and already traditional - event, where film critics from all over the world gather to compare notes on the status of Romanian cinema.

Cecil B. DeMille and the Art ofApplied Suggestibility
Authors: Kozlovic Anton Karl
Published: August 2019

CECIL B. DE MILLE AND THE ART OF APPLIED SUGGESTIBILITY: VIOLENCE, SEX AND FALSE MEMORIES WITHIN HIS BIBLICAL (AND OTHER) CINEMA AbstractLegendary producer-director Cecil B. DeMille is an unsung auteur who helped co-found both Hollywood and Paramount studios and became America's pre-eminent biblical filmmaker. He employed many artistic strategies, but none as politically astute as the deliberate engineering of false memories in a deliberate act of applied suggestibility. This trademark effort allowed DeMille to achieve desired audience reactions whilst simultaneously avoiding censorship problems and moral vigilantes who thought they saw objectionable things in his movies but which were not actually there. Consequently, selected DeMille films and the associated critical literature were inspected, reviewed and integrated into the text to enhance narrative coherence utilizing humanist film criticism as the guiding analytical lens. It was concluded that DeMille was a master filmmaker and that his cinematic oeuvre warrants a more...
The Gothicization of the Harry Potter Series
Authors: Sanna Antonio
Published: August 2019

THE GOTHICIZATION OF THE HARRY POTTER SERIES: THE PROGRESSIVE TRANSPOSITION OF THE GOTHIC INTO THE FILMS Abstract In this paper I shall argue that the Harry Potter cinematographic adaptations of J. K. Rowling's novels gradually enacts a transgeneric crossing of the Gothic into the genre of the fantastic. Specifically, by utilizing Robert Mighall's argument that the "Gothic is a process, not an essence; a rhetoric rather than a store of universal symbols", I shall argue that such a transposition is progressively achieved by means of the representation of an imagery clearly recalling Gothic settings, figures and atmospheres, and through the use of a series of thematic preoccupations that are usually present in Gothic texts. According to the critic Robert Mighall, "The Gothic is a process, not an essence; a rhetoric rather than a store of universal symbols; an attitude to the past and the present, not a free floating...
A New Frontier for Visual Culture

A NEW FRONTIER FOR VISUAL CULTURE: THOUGHTS ON THE PRODUCTION AND CONSUMPTION OF DIGITAL DEEP-SEA IMAGERY The following discussion is a response to the proliferation of digital deep-sea imagery that has been emerging since the mid-1990s. Here, digital imagery is understood in William J. Mitchell's (1994, 7) postmodern social and cultural terms as "a medium that privileges fragmentation, indeterminacy, and heterogeneity and that emphasizes process or performance", and an "opportunity to expose the aporias of photography's construction of the visual world". A stock of visual documentation (still and moving images) is growing each day - widely available on the internet, in books (both for adults and for children), and in movie theatres internationally. IntroductionMindful of this new entertaining and educational material, it strikes me as problematic that there is a paucity of critical inquiry into the curatorial and signifying practices associated with its dissemination, certainly in terms of...

HIGHLIGHTS FROM THE SHANGHAI INTERNATIONAL FILM FESTIVAL 2012 The Shanghai International Film Festival may be the most prominent film festival in Mainland China, but its potential is untapped. If bureaucratic and censorship barriers were eased, Shanghai would be positioned to reshape its A-list status beyond paper. At the very least the festival could correct its blind spots, such as crafting a richer program in lieu of sweeping mainstream content, and ideally launching a serious focus on Mainland and Sinosphere cinema. Still, Shanghai is a good stop on the calendar to sample state sanctioned Mainland films unlikely to see the theatrical light of day elsewhere. Of its range of contemporary world cinema, the festival's annual showcase of Japanese films has drawn consistently huge crowds. But in the interim audiences will be watching if the latest round of political tensions between China and Japan will result in cinema as collateral damage....

PHYSICIAN, HEAL THYSELF: THE SON'S ROOM Although we know that after such a loss the acute state of mourning will subside, we also know we shall remain inconsolable and will never find a substitute. No matter what will fill the gap, even if it be filled completely, it nevertheless remains something else. And actually this is how it should be. It is the only way of perpetuating that love which we do not want to relinquish. Sigmund Freud, Letter to Ludwig Binswanger (1929) PHILIP FRENCH makes the point that La Stanza del Figlio (the Italian title of The Son's Room) carries a pun. In addition to 'the room' explicit in the English version, stanza also means a verse in both languages, thus suggesting the idea of 'a poem or part of a life left standing' (2002).

THE CINEMA AND REAL TIME: AN INVESTIGATION OF THE MEDIUM'S RELATION TO TIME Christian Marclay's deranged clockCHRISTIAN Marclay's The Clock (2010), the film that won the Golden Lion at this year's Venice Biennale and was quickly snapped up by a number of major galleries (including MOMA and the National Gallery of Canada) is literally a clock, or a perfect simulacra of one. Having found a clip for every minute of the day, Marclay spliced them together to form the moving-image of a 24-hour clock, which, as if to make the likeness complete, is projected in real-time. The discovery that there is an image for every minute of the day serves as a reminder that the cinema has always been concerned if not obsessed with time. However, the concern has not always been with real-time. One could even say that the cinema has always presented us with the opposite;...
Redacted: The Iraqi War according to YouTube
Authors: Arnold Sarah
Published: August 2019

REDACTED: THE IRAQI WAR ACCORDING TO YOUTUBE Using the increasingly popular format and style of the mockumentary or 'found footage', Brian de Palma's Redacted (2007) aims to present one minor yet horrific event of war through the media with which contemporary audiences are, by this stage, familiar: amateur footage (such as that uploaded to YouTube and other sites daily), video-messaging, news and documentary footage, as well as CCTV and other surveillance footage. The proliferation of such war images may point to the collapsing of spatial and geographical boundaries by bringing the war closer to home and by making it more personal. Yet, as the film indicates, this very imagery serves to depersonalize war for the spectator-viewer, as well as for the participants and soldiers, who perceive themselves as filmmakers and stars. Indeed throughout the film 'found' excerpts from Arab, French and US media point to the globalized investment in...
From Fordism to Post-Fordism: Representation of Work in the Films about Nazi Concentration Camps
Authors: Mazierska Ewa
Published: August 2019

FROM FORDISM TO POST-FORDISM: REPRESENTATION OF WORK IN THE FILMS ABOUT NAZI CONCENTRATION CAMPS Nazi concentration camps in cinema, as well as in other media, tend to be represented as an aberration from the human norm. Watching films about the camps (the mainstay of the Holocaust film), we get the impression that there is a clear division between life in a camp and normal life. The inclusion of walls and barbed wire, marking the boundary between the prisoners' world and that of free people, as well as between camp and non-camp stages of the characters' lives confirm this impression. I also regard camps as extraordinary. This extraordinariness has a double meaning. In some aspects Nazi camps deviated qualitatively from ordinary institutions and everyday practices. In others, they were different in a sense of intensifying certain aspects of practices tested in other historical circumstances or even regarded as normal and...

INTERVIEW WITH DAVIDE POZZI, DIRECTOR, L'IMMAGINE RITROVATA Less often under the spotlight than filmmaking, producing or reviewing, film preservation and restoration are nevertheless crucial in keeping film cultural heritage alive for future generations. While preservation focuses on the proper storage of a film in a climate-controlled environment and may sometimes include film repair and copying, restoration aims to return a film to its entirety and original image quality as intended by its filmmakers, either through photochemical or digital processes. In recent decades, it has become increasingly clear to filmmakers, film historians, archives and libraries around the world that there is an urgent need to preserve and restore the fast growing amount of recorded film material that is rapidly being lost to deterioration. At the same time, film studios and film archives are realizing the commercial potential of restoring their collections of classics and re-releasing them theatrically as well as...

Clash of the Titans as a Parallel Remake

Published: August 2019

REINTERPRETING MYTH AND FILM: CLASH OF THE TITANS AS A PARALLEL REMAKE AbstractLouis Leterrier's film Clash of the Titans (2010) is a new version of both Desmond Davis's 1981 film by the same title and the Greek myth of Perseus. Categorizing Leterrier's work is nevertheless problematic because the film partly defies many definitions of cinematic remakes elaborated by the critics in the past decades. Clash of the Titans shall be examined and evaluated in relation to both its precursor texts, with specific attention to its significantly different treatment of their narrative units. Although remakes have been produced since the very creation of cinema at the end of the nineteenth century and proliferate nowadays (Forrester 89), critics consider them as "an underexplored subject" (Forrester and Koos 26), whose definition(s) and classification(s) are still being scrutinized and debated. Remakes are often examined in terms of their fidelity to the primary...

ADAPTING THE TEMPEST: JULIE TAYMOR'S REVELS Adaptations and appropriations of Shakespeare's plays demonstrate the unending life of a series of canonical texts that still invite numerous forms of interpretation. Simultaneously, they also offer a tool for the (re)interpretation of the English playwright's works. This is definitely the case of Julie Taymor's recent film The Tempest (2010), which partially alters the structure of Shakespeare's last solo play, but also actively engages with the academic debates on the work's thematic concerns. Nevertheless, Taymor's film could be seen as faithful to the original source and as fully realizing on the screen its fantastic elements, especially through the use of the special effects. Taymor's The Tempest utilizes the original heightened language of the seventeenth century - which certainly gratifies those spectators that enjoy what Stephen Greenblatt has defined as Shakespeare's "infinite delight in language"(1) - and maintains the main dialogues of the original...

Tracing its origins to expanded cinema and video art in the 1970s, moving image installation is now ubiquitous in public museums and private galleries. This is at a time when access to experimental work via public service versions of television has now all but disappeared.(1) In the two decades since, as television channels have proliferated, choice has actually narrowed. Moving image installations are visible in a diversity of art environments from gallery spaces to site-specific work in urban or industrial pop-ups. Multi-screen configurations are not easily arranged in cinemas or easily watched on television sets, let alone computers. The small portable digital screens may issue a blizzard of information and imagery everyday, but their size and scale...

Taylor–Couette flow of a fractional second grade fluid in an annulus due to a time-dependent couple
Authors: Imran M. , Kamran M. , Athar M. , Zafar A. A. A.
Published: August 2019

Exact solutions for the velocity field and the associated shear stress, corresponding to the flow of a fractional second grade fluid between two infinite coaxial cylinders, are determined by means of Laplace and finite Hankel transforms. The motion is produced by the inner cylinder which is rotating about its axis due to a time-dependent torque per unit length 2πR1ft2. The solutions that have been obtained satisfy all imposed initial and boundary conditions. For β → 1, respectively β → 1 and α1 → 0, the corresponding solutions for ordinary second grade fluids and Newtonian fluids, performing the same motion, are obtained as limiting cases.
On a three-tier ecological food chain model with deterministic and random harvesting: A mathematical study
Authors: Mukhopadhyay B. , Bhattacharyya R.
Published: August 2019

In the present study, we consider a nutrient-autotroph-herbivore ecosystem model where the herbivore species is assumed to have a commercial value. We use a Holling type-II harvest function to model density dependent herbivore harvesting. Stability criteria of the resulting model is investigated both from analytical and numerical viewpoints. The investigation revealed the existence of a number of threshold values of the harvest rate that have a remarkable influence on the system dynamics. Next we incorporate a noise term in the parameter representing harvest rate to model the phenomenon of poaching as random harvesting. The stochastic model is analyzed for exponential mean square stability and the resulting criteria in terms of harvest related parameters obtained. These parameter thresholds could be utilized to develop effective harvesting strategies and wildlife management policies which take into account the overall survival of the ecological populations.
Soret and Dufour effects on mixed convection in a non-Darcy porous medium saturated with micropolar fluid
Authors: Srinivasacharya D. , RamReddy Ch.
Published: August 2019

In this paper, the Soret and Dufour effects on the steady, laminar mixed convection heat and mass transfer along a semi-infinite vertical plate embedded in a non-Darcy porous medium saturated with micropolar fluid are studied. The governing partial differential equations are transformed into ordinary differential equations. The local similarity solutions of the transformed dimensionless equations for the flow, microrotation, heat and mass transfer characteristics are evaluated using Keller-box method. Numerical results are presented in the form of velocity, microrotation, temperature and concentration profiles within the boundary layer for different parameters entering into the analysis. Also the effects of the pertinent parameters on the local skin friction coefficient and rates of heat and mass transfer in terms of the local Nusselt and Sherwood numbers are also discussed.

Published: August 2019

Two-dimensional steady natural convective flow in a square inclined enclosure with vertical vee-corrugated sidewalls and horizontal top and bottom surfaces has been numerically studied. A discrete heat flux strip of 24% of the total length is flush-mounted on the bottom wall, while the other non-heated parts of the bottom wall and the top wall are considered adiabatic. The two vee-corrugated sidewalls are maintained at constant cold temperature. Grashof number is varied from 103 to 106, corrugation frequency is varied from 0.5 to 2.0, corrugation amplitude has been fixed at 10% of the enclosure height and the enclosure inclination angle is varied to 0◦, 10◦, 20◦ and 30◦ respectively. The enclosure is filled with air (Pr = 0.71). The flow has been assumed to be steady and laminar. Fluid properties have been assumed constant except for the density change with temperature that gives rise to the buoyancy forces. The solution has been obtained using the governing equations written in terms of dimensionless variables. The dimensionless governing equations are solved using finite volume method. Results are presented in the form of streamline and isotherm plots. The results of the present work show that the natural convection phenomenon is greatly affected by increasing the enclosure inclination angle. The variation in the average Nusselt number at the bottom wall, where the heat source exists and the maximum dimensionless temperature are also presented. The results are compared and found to be in a good agreement with other published results.
A seventh order numerical method for singular perturbed differential-difference equations with negative shift
Authors: Phaneendra Kolloju , Reddy Y. N. N. , Soujanya GBSL.
Published: August 2019

In this paper, a seventh order numerical method is presented for solving singularly perturbed differential-difference equations with negative shift. In recent papers the term negative shift has been used for delay. Such problems are associated with expected first exit time problem of the membrane, potential in models for neuron and in variational problems in control theory. In the numerical treatment for such type of boundary value problems, we first use Taylor approximation to tackle terms containing small shifts which converts into a singularly perturbed boundary value problem. This two point boundary value problem is transformed into general first order ordinary differential equation system. A discrete approximation of a seventh order compact difference scheme is employed for the first order system and solved by using the boundary conditions. Several numerical examples are solved and compared with exact solution. We also present least square errors, maximum errors and observed that the present method approximates the exact solution very well.

Feedback linearization-based vaccination control strategies for true-mass action type SEIR epidemic models
Authors: De la Sen Manuel , Ibeas Asier , Alonso-Quesada Santiago
Published: August 2019

This paper presents a feedback linearization-based control strategy for a SEIR (susceptible plus infected plus infectious plus removed populations) propagation disease model. The model takes into account the total population amounts as a refrain for the illness transmission since its increase makes more difficult contacts among susceptible and infected. The control objective is novel in the sense that the asymptotically tracking of the removed-by-immunity population to the total population while achieving simultaneously the remaining population (i.e. susceptible plus infected plus infectious) to asymptotically converge to zero. The vaccination policy is firstly designed on the above proposed tracking objective. Then, it is proven that identical vaccination rules might be found based on a general feedback linearization technique. Such a formal technique is very useful in control theory which provides a general method to generate families of vaccination policies with sound technical background which include those proposed in the former sections of the paper. The output zero dynamics of the normal canonical form in the theoretical feedback linearization analysis is identified with that of the removed-by-immunity population. The various proposed vaccination feedback rules involved one of more of the partial populations and there is a certain flexibility in their designs since some control parameters being multiplicative coefficients of the various populations may be zeroed. The basic properties of stability and positivity of the solutions are investigated in a joint way. The equilibrium points and their stability properties as well as the positivity of the solutions are also investigated.

Authors: Kočetova Jelena , Šiaulys Jonas
Published: August 2019

We investigate the asymptotic behavior of the Gerber–Shiu discounted penalty function ɸ(u) = E(e−δT 1{T <∞} | U(0) = u), where T denotes the time to ruin in the Erlang(2) risk process. We obtain an asymptotic expression for the discounted penalty function when claim sizes are subexponentially distributed.

Complex dynamics of a three species food-chain model with Holling type IV functional response
Authors: Upadhyay Ranjit Kumar Kumar , Raw Sharada Nandan Nandan
Published: August 2019

In this paper, dynamical complexities of a three species food chain model with Holling type IV predator response is investigated analytically as well as numerically. The local and global stability analysis is carried out. The persistence criterion of the food chain model is obtained. Numerical bifurcation analysis reveals the chaotic behavior in a narrow region of the bifurcation parameter space for biologically realistic parameter values of the model system. Transition to chaotic behavior is established via period-doubling bifurcation and some sequences of distinctive period-halving bifurcation leading to limit cycles are observed.

Authors: Juozapavičius Algimantas , Bacevičius Gytis , Bugelskis Dmitrijus , Samaitienė Rūta
Published: August 2019

In the diagnosis and treatment of epilepsy, an electroencephalography (EEG) is one of the main tools. However visual inspection of EEG is very time consuming. Automatic extraction of important EEG features saves not only a lot of time for neurologist, but also enables a whole new level for EEG analysis, by using data mining methods. In this work we present and analyse methods to extract some of these features of EEG – drowsiness score and centrotemporal spikes. For spike detection, a method based on morphological filters is used. Also a database design is proposed in order to allow easy EEG analysis and provide data accessibility for data mining algorithms developed in the future.
Geodesic distances in the maximum likelihood estimator of intrinsic dimensionality
Authors: Karbauskaitė Rasa , Dzemyda Gintautas , Mazėtis Edmundas
Published: August 2019

While analyzing multidimensional data, we often have to reduce their dimensionality so that to preserve as much information on the analyzed data set as possible. To this end, it is reasonable to find out the intrinsic dimensionality of the data. In this paper, two techniques for the intrinsic dimensionality are analyzed and compared, i.e., the maximum likelihood estimator (MLE) and ISOMAP method. We also propose the way how to get good estimates of the intrinsic dimensionality by the MLE method.

Authors: Malukas Raimondas
Published: August 2019

In the paper a weighted quadratic variation based on a sequence of partitions for a class of Gaussian processes is considered. Conditions on the sequence of partitions and the process are established for the quadratic variation to converge almost surely and for a central limit theorem to be true. Also applications to bifractional and sub-fractional Brownian motion and the estimation of their parameters are provided.
On a variance related to the Ewens sampling formula
Authors: Manstavičius Eugenijus , Žilinskas Žydrūnas
Published: August 2019

A one-parameter multivariate distribution, called the Ewens sampling formula, was introduced in 1972 to model the mutation phenomenon in genetics. The case discussed in this note goes back to Lynch’s theorem in the random binary search tree theory. We examine an additive statistics, being a sum of dependent random variables, and find an upper bound of its variance in terms of the sum of variances of summands. The asymptotically best constant in this estimate is established as the dimension increases. The approach is based on approximation of the extremal eigenvalues of appropriate integral operators and matrices.
On the kinetics of the Langmuir-type heterogeneous reactions
Authors: Skakauskas Vladas , Katauskis Pranas
Published: August 2019

In this paper we investigate three two-dimensional in space mathematical models of the kinetics of unimolecular heterogeneous reactions proceeding onto planar surfaces. All models include the diffusion of the reactant from a bounded vessel towards an adsorbent, adsorption of the molecules of the reactant, their desorption, conversion (reaction) of the adsorbate into a product, instantaneous product desorption, and the diffusion of the product from the adsorbent into the same vessel. One of these models is based on the Langmuir-type kinetics of the surface reactions, the other one is based on the local steady-state value of the surface coverage, and the last one, in addition to the first model, involves the diffusion of the adsorbate along the adsorbent. Diffusivity of all species is assumed to be constant.
Models were solved numerically by using the finite difference technique. By changing input parameters the effects of the rate constants of the reactant adsorption, desorption, and reaction and the influence of the surface diffusion of the adsorbate and approximation of the surface coverage by its steady-state value on the kinetics of surface reactions were studied numerically.

Authors: Bratčikovienė Nomeda
Published: August 2019

We present adapted SETAR (self-exciting threshold autoregressive) model, which enables simultaneous estimation of nonlinearity and unobserved time series components. This model was tested on real Lithuanian harmonised consumer price index (HCPI) time series, covering the period from January 1996 to December 2009. The results show that adapted SETAR model is able to capture features of the real time series with complex nature. ARIMA model has also been used for the same time series for the comparison. Evaluated models and results of the comparison are presented in this work.

On the existence of solutions to the fractional derivative equations d(alpha)u/dt(alpha)+Au = f, of relevance to diffusion in complex systems
Authors: Heibig Arnaud , Palade Liviu Iulian Iulian
Published: August 2019

Fractional derivative equations account for relaxation and diffusion processes in a large variety of condensed matter systems. For instance, diffusion of position probability density displayed by a random walker in complex systems – such as glassy materials – is often modeled by fractional derivative partial differential equations. This paper deals with the existence of solutions to the general fractional derivative equation dαu/dtα+Au = f for 0 < α < 1, with A a self-adjoint operator. The results are proved using the von Neumann–Dixmier theorem.

Prediction of a composite indicators using combined method of extreme learning machine and locally weighted regression
Authors: Rukšėnaitė Jurga , Vaitkus Pranas
Published: August 2019

In this paper, a method of artificial neural networks (NN) is proposed as an alternative tool for the one-step-ahead prediction of composite indicators (CIs) of Lithuania’s economy. CI is composed of widely used social and economic indicators. The NN is applied for forecasting CI during the financial crisis and later periods (2008–2010) on the basis of data of earlier years (1998–2007). In this work, the Extreme Learning Machine (ELM) algorithm is combined with locally weighted regression. The analysis shows that the prediction error of a testing sample is statistically smaller compared to Levenberg–Marquardt or ELM methods.
