Повний текст джерелаThriller is a favourite genre to many and has been around for longer than most think. Originally starting as a genre of literature, it has evolved into one of the most sought after genres within film. Early notable works such as Alfred Hitchcock's films in the mid 1900s have paved the way for the genre and solidified it’s editing and cinematography into what we have today. Despite its humbling beginnings in the mid 1900s the techniques, although somewhat repetitive, still manage to stay relevant today and have only gotten more advanced with time. In this article, we study the fundamentals within the thriller genre, the editing and cinematography techniques that are utilized; camera framing, cutting, PoV and color. In this study our main focus we intend to work towards is understanding why these techniques are used and the tendencies in which they are facilitated. Although we also intend to go in depth into the thriller genre as a whole and despite the repetitiveness of the genre, why it manages to stay relevant today and how editing and cinematography plays a big part in amplifying the emotions and feelings associated within thrillers in which these tendencies stem from.

Повний текст джерелаVid årsskiftet 2010-2011 övergick Sverige från nationell standard till de europeiska standarderna för konstruktion, Eurokoderna. I den europeiska standarden, precis som i den gamla, kan betongpelare förenklat branddimensioneras med hjälp av tabellvärden. Kraven på minsta tvärsnitt har dock blivit avsevärt större. Detta har varit blivit svårt att förena med önskemål från arkitekter. Det är även möjligt att branddimensionera betongpelare med beräkningar. Detta är dock ovanligt. Brandförloppet i en brandcell kan förenklat delas in i uppvärmning, fullt utvecklad brand och avsvalning. Tiden för de olika faserna, liksom temperaturen, påverkas av en mängd faktorer. Några av dessa är mängden brännbart material, hur stora öppningar som finns och brandcellens geometri. I Eurokoderna finns standardiserade brandförlopp som kan användas vid dimensionering. En av dessa kallas standardbrandkurvan. Tabellvärdena är baserade på standardbrandpåverkan. Vid branddimensionering används en annan lastkombination än vid normaltemperaturdimensionering. Denna lastkombination ger en lägre last än vid brottgränsdimensionering. Både betong och armeringsstål förlorar bärförmåga vid förhöjda temperaturer. För armeringsstål är denna reducering väl dokumenterad. För betong, som inte är ett homogent material, är hållfastheten svårare att beräkna. Betongpelare kan dimensioneras enligt tre metoder: Vedertagna och beprövade detaljlösningar (Tabellerade värden) Förenklade beräkningsmetoder Avancerade beräkningsmetoder Fokus i denna rapport ligger på en av de förenklade beräkningsmetoderna, 500 °C isotermmetoden. Den utgår från att betong som har en temperatur över 500 °C försummas, emedan betong med en temperatur under 500 °C antas ha sin fulla bärförmåga. Därefter beräknas en reducerad hållfasthet för armeringsstängerna utifrån den temperatur de uppnår. Dimensionering sker sedan enligt traditionella metoder. Arbetet med att beskriva hur isotermmetoden ska användas har försvårats av bristande information i Eurokoderna. Dessutom finns det få personer som känner till hur metoden ska användas i praktiken. Detta har resulterat i vissa antaganden som underbyggts av logiska resonemang. För att kunna jämföra isotermmetoden med tabellerade värden kontrollerades en pelare för 60 och 90 minuters standardbrandpåverkan (se Bilaga A). Resultatet visade att pelare kan klara kraven med mindre tvärsnitt än i tabellen. Vid dimensioneringen erhölls ett tvärsnitt som låg mellan de nya och de gamla kraven. 500 °C isotermmetoden är den enklaste av de förenklade beräkningsmetoderna för betongpelare. Detta innebär dock inte att den är enkel. Trots att modellen i denna rapport har avgränsats till centriskt belastade, cirkulära pelare är metoden tidskrävande. Troligt är därför att den bara kommer att användas vid speciella fall då tabellmetoden inte är tillämpbar.

Повний текст джерелаThe long-established and well-known devices for sample pretreatment and/or analysis have been widely studied to new adaptations due to the miniaturization trend. The production of these miniaturized systems requires not only new approach on manufacturing and methodology but also depends on surface modification for performance improvement or new applications development. Surface modification using plasma-produced thin films is well established in Microelectronics. Therefore, the aim was to evaluate the use of Plasma polymerized Tetraethylorthosilicate surface modification on manufacturing of miniaturized structures. The main use of such a modification is on devices for sample pretreatment - retention, pre-concentration, or even for protecting detection system surface. The methodology carried out tested these thin films in channels and selective membranes. Whereas channels used three-dimensional and planar geometries, membranes were tested only with planar geometries. Three-dimensional microchannels, used in gaseous or liquid phase, were tested for retention/preconcentration of volatile organic compounds (VOCs). Retention of inorganic compounds in aqueous liquid phase was tested using not only three-dimensional and planar microchannels but also membranes. Protection of detection systems required planar geometry. TEOS thin film was tested after: deposition, ageing for several months; exposition to severe environmental conditions that leads to hydrolysis of organic radicals present in the film; surface hydrophobization due to hexamethyldisilazane, HMDS, exposure. Manufacturing of miniaturized three-dimensional and planar devices leads to some solutions on sample pretreatment and respective analysis methodology. These devices can be used for separation, retention and pre-concentration. The results pointed out that a threedimensional microchannel with plasma deposited TEOS film previously hydrolyzed allows ion retention and clusters formation in a copper aqueous solution. Furthermore, in gaseous phase, VOCs in small concentration can be separated whereas polar compounds can be retained. Planar device allows separation of inorganic ions in a structure similar to the ones used in electrochromatography. Small and low-cost devices are thus here provided, which can easily be machined and are very useful in the chemical analysis field. The three-dimensional microchannel presented behavior similar to the one of a chromatographic pre-column. This microchannel can also be easily adapted to a miniaturized chromatograph. Other possible use is in sample pretreatment, coupled ahead of non-specific detectors, such as electronic noise arrays, since it can decrease the numbers of compounds to be detected and, consequently, reduce drawbacks concerning results analysis.

Повний текст джерелаUppsatsen har som utgångspunkt att studera hur vår identitet som svensk idealiseras i film och då främst genom Lars Hallströms Mitt liv som hund (1985) och Colin Nutleys Änglagård (1992).
Teorin som valts för analysen är identifikationsframställning genom Frankfurterskolans ideologikritik, Foucaults läror om diskurs, kunskap och makt samt identitetsbegreppet i sig och idenitetsframställning. Genom tillämpandet av teorin ges möjligheten att kritiskt granska och omläsa de ovan nämnda filmerna i en omfattande analys. Metoder för uppsatsens analys är en fördjupad närläsning och genomgående omläsning utav de två filmerna.
Uppsatsen utgår även från två frågeställningar som blir besvarade i ett analysresultat och sammanfattning. Genom en näranalys av filmerna ges en möjlighet att se hur propaganda uppstår och verkar, då filmernas idealiserande framställning kan misstas och brukas som sanning. I analysernas reslutat framgår det även att svenskhet vilar på en grund av föreställd gemenskap där man genom att tillämpa Peter Norman Waages teorier ser att idenitetsframtällningen som nation grundas på det så kallade ”omvända kylskåpet”.Identitet sammanför på samma gång som det söndrar då det verkar med värme inåt och kyla utåt, likt ett omvänt kylskåp.

Повний текст джерелаThe study of color in the cinema has reached relevant research dimensions throughout the first decade of the 00\'s. Several publications have mapped the broadest theme in which color is put in film analysis. Therefore, it is possible to revisit some past works and move on to new looks and interpretations. Under the domain of the color, I propose the film analysis of Pierrot le fou (Jean-Luc Godard) and Le bonheur (Agnès Varda). In the investigation of the chromatic system of these moviemakers, it is possible to evaluate interdisciplinary questions like the representation of France in the 60\'s and gender relations.

Повний текст джерелаThis doctoral thesis studies columns in reinforced concrete frames in fire situation subjected to combined axial and flexural loads, considering their interaction with the structure. In the analyzes, geometric non-linearity, material non-linearity, concrete cracking, and mechanical properties of concrete and steel, are considered varying with temperature, e.g. strength and young\'s module loss and the stress-strain curves. In addition, variations of the thermal properties are considered, e.g. specific heat, thermal conductivity, and thermal elongation. Initially, cross-sectional analysis of reinforced concrete columns in fire situation, submitted to combined axial and flexural loading are performed. The performance is done, using a code or program developed by the author of this thesis. In these analyzes the physical non-linearity of the material and the variation of the mechanical and thermal properties of the concrete and the steel are considered. Columns are analyzed in different situations, with focus on stresses, strains and the effects of the restrains. Subsequently, thermomechanical analyzes of two-dimensional and three-dimensional reinforced concrete frames are performed using the DIANA Displacement Analyzer program. In these analyzes the geometric non-linearity, the physical non-linearity of the material and the variation of the mechanical and thermal properties of the concrete and steel are considered. A detailed study is conducted with emphasis on the effects of axial and rotational restraints, evaluating its consequences on the resistance and the behavior of the reinforced concrete columns in fire situation. Several structures are analyzed considering fires located in compartments of them and are evaluated the forces resulting from the interaction between the columns and the rest of the structure. Finally, from the results obtained in the analyzes carried out in DIANA Displacement Analyzer, the values of the loading forces, resistant forces, and some important relations between them are calculated.

Повний текст джерелаWithin the set of aspects related to the development of researches in steel and composite steel and concrete structures, stands out with great importance and interest, aiming to dimension, the consideration of structural elements subjected to high temperatures. In this way, the present work has as main objective to propose the construction of three-dimensional numerical models of steel columns that belong to current structural systems of civil construction, for examination in fire situation, aiming to simulate numerically the evolution of temperature levels throughout of time with later termoestrutural coupling. It will be considered a parametric analysis in order to vary the total and partial axial restraint in respect to the axial displacements, since the free end situation until the complete restriction in response to the consideration of support for the fixed type, for example. The numerical results are compared to experimental tests made by other authors, as well as with others numerical works already published. Answers are obtained from axial and lateral displacements of the thermo structural model to many displacement of wall related to the profile, also charts of adding axial force introduced into the system by the axial restraint. The results of the current research could serve as a basis for further research in both the numerical field or experimental, also for future revisions of ABNT NBR 14323:1999, aiming to see situations of interest not studied in the same normative document. The results of this work show that consideration of thermal field with the inclusion of masonry in the thermo structural model can, significantly, improve the performance of the structural element in a fire situation.

Повний текст джерелаIn spite of the several factors that influence the behavior of concrete columns under fire conditions, there is a belief among the research community, that the high-strength concrete is more susceptible to explosive spalling than normal-strength concrete. This doubt, in part, is attributed to the small unreinforced concrete samples (specimens) used in experimental programs, to evaluate the fire resistance of structural concrete. On the other hand, relevant aspects as the coarse aggregate type used in the concrete mixture, as well as the age and content moisture (relative humidity) are not considered in the researches and sometimes simply omitted. This research presents a pioneer experimental program, carried out in Brazil on a high strength colored reinforced concrete column (HSCC) with 200cm high, eight yearsold, fc,8years of 140MPa, basalt coarse aggregate, cross section of 700mm x 700mm, tested under no load and with three faces exposed to a standard fire curve ISO 834 for a period of 180min (3h). The column prototype is a replica of the actual columns of the e-Tower Building, constructed in 2002 in São Paulo city, Brazil. The results demonstrated concrete column integrity under experimental fire and that the iron oxide pigments can work as an excellent natural thermometer, contributing in the evaluation of the structure post-fire.

The object of this research work is aimed at examining the basic material properties of fire resistant steel and its application on the welded box column. Experimental studies included the creep test, axial compression test and fire duration test of box columns. The effect of the slenderness of box column and the effect of restraining force during fire event were examined in the experimental program. Nonlinear finite element studies were carried out to study the behavior of box column under fire load and good correlations were obtained between analytical and experimental studies. Based on these experimental and analytical studies, suggestions are made to account for the behavior of box column under fire load.

With the advancement of metal production, a new type of steel plate, Fire Resistant Steel (FRS), has been developed to conquer inherent weakness of conventional steel. FRS possesses good mechanical properties at high temperature. Using FRS can also reduce the demand of fire proofing material. However, there is a lack of knowledge about the structural behavior of steel structure mode of FRS steel. This research work is aimed at examining the fundamental behavior FRS as well as structural behavior of welded steel box column under axial load. Blind Hole Method was adopted to determine residual stresses of FRS box column. Based on the experimental and analytical studies, recommendations were made for the design and fabrication of welded steel box column utilizing the FRS.

The sensitiveness to temperature of steel becomes a weakness for steel structures. Since the mechanical properties of steel decay significantly at high temperatures, the loading capacity of steel structures in fires will reduce intensively. The failure of beam-column joints frequently induces the collapse of steel structures. However, the behavior of steel beam-column connection at elevated temperatures is very complicated and it has not been fully studied. This study investigates the fire response of steel semi-rigid beam-column moment connections made with H-shape beam and H-shape column. The general purpose finite element software ANSYS was adopted. The numerical model was verified by the full-scale fire tests implemented in the building fire laboratory center of the Architecture and Building Research Institute (ABRI) in Taiwan, and its results were found to agree well with experimental results. The formula to estimate the behavior of steel semi-rigid beam-column moment connections at constant temperature was established from a series of ANSYS numerical analyses and was proved to be suitable for using in the increasing four-side-heated cases. Further, the estimating formula of the connection rotation caused by thermal expansion was established for the increasing three-side-heated cases. The method that considers the influences of thermal expansion and loading (including self weight) conditions separately proposed by this study can provide for follow-up studying the behavior of steel structure in fire.

In film production, the cost of actors is one of the most important budgeting issues. In this study, we determine the sequence of the scenes of shooting days so that the total holding cost of actors’ and the total operating cost of the shooting days can be minimized. We also consider the daily working hours as the decision variable, which is defined as the total duration of scenes distributed in a single day. In this research, we develop a mixed integer programming model. Since the problem is NP-hard, we propose an Ant Colony Optimization (ACO) algorithm to solve the film production scheduling problem. A randomized variable neighborhood decent (RVND) is used as the local search approach to improve the solution. To access the effectiveness of the proposed ACO algorithm, we test three sets of benchmark instances from the literature. The first set includes 8 small sized instances. Our ACO can obtain all the optimal solutions. The second set has 240 instances. We can improve the best found solutions by up to 4.93%. The third set includes 1000 instances. We can found all best known solutions. The computational results indicate that of our ACO algorithm are able to provide good solutions within short computational times.

In film production, budgeting is one of the most important issues. In this study, we present the cost minimization issue in talent scheduling and scene scheduling. We determine the sequence of the scenes of shooting days so that the total hold cost of actors can be minimized. We also concern about the daily working capacity, which defines the total duration of scenes allocated in a single day. Our objective function is the total hold cost of all actors’ hold cost and the total operating cost of the active shootings days. This problem is already known to be strongly NP-hard and computationally challenging. In this thesis, we propose an algorithm based upon Ant Colony Optimization (ACO) to solve the scheduling problem. We examine the computational results of our ACO algorithm by using different parameter settings. The computational experiments reveal that the ACO algorithm is more effective and more efficient in obtaining near-optimal solutions.

The study examines the fire performance of welded SN490 H columns experimentally and analytically. Two series of steel columns, stub columns and columns with longer length, were centrally loaded at specified temperature to examine their structural behavior exposure to fire. The aspects considered in this study include width-to-thickness ratio (b/t), slenderness ratio (L/r), ultimate strength, ductility, temperature and failure modes etc. Results of this study indicates that ultimate strength of steel columns decrease with the increasing of the width-to-thickness ratios, slenderness ratio and temperature. The residual stress is released at elevated temperature and its effect on column strength can be neglect. Current design criteria developed at ambient temperature is able to prevent premature failure of local buckling of SN490 steel columns subjected to axial compression either at ambient temperature or at elevated temperature. Inelastic steel columns retain more than 60% of their ambient temperature strength at 500oC. And, column strengths drop to approximately 50% and 40% of the ambient temperature strength as temperature reach 550oC and 600oC, respectively. Finally, the strength reduction factors of SN490 welded of steel column at elevated temperature are proposed based on the results of this study.

According to the test of the full-scale joints of the steel beam-column in fire environment, the composed beam-column frame is analyzed by the general purpose finite element software ANSYS. The material properties of steel in high temperature proposed by EUROCODE3 was use in this study. The numerical modeling of steel beam-column joints in fire environment has been proven by simulating the ABRI fire experiment. This thesis used different stress-strain curve in high temperature environment, and compared the result of analysis with experiment.

ZnO nano-column thin films were deposited on the Si (111) substrates by reactive RF magnetron sputtering at room temperature in four different concentrations of O2.(20%, 40%, 60%, 80%). The crystal structure after annealing and optical properties by PL measurements of different excitation angle (90o and 45o) of ZnO thin films are discussed. The crystal structure of all samples by XRD measurements are the (002) preferred orientation. The ZnO thin films are nano-column structure by SEM measurements. But the structure of 80% ZnO thin film after annealing was changed to the bluk structure. In PL measurements of 90o excitation angle, for 20% and 60% ZnO thin films, their luminescence emission sgnals are not intrinsic results of ZnO thin films and the emission intensity is very weak. But the luminescence emission intensity of 80% ZnO thin films is normal, so we use PL measurement system of 90o excitation angle to analyze 80% ZnO thin films. In PL measurements of 45o excitation angle, we can find the emission results of 60% ZnO thin film with multi-phonon resonant Raman scattering (MRRS) signals, because the intrinsic luminescence emission signal of 60% ZnO thin film is very weak. Finally, using interference signals from defect emission of 20%, 40%, 60% ZnO thin films to calculate the thin films thickness and refractive index, then the results are compared with thin films thickness of SEM measurement and refractive index of ZnO bulk.
