Reading is an important skill for developing second language competence. The success of a learning a second language is by taking the power of reading. In the classroom, we will face many techniques applied to the students under the expectation that they are able to or easy to understand the lesson. For a teacher, it is necessary to find new teaching media to overcome the problems and not to forget to motivate the students. In this paper, the writer wants to know the effect of picture as a media to improve students’ reading comprehension. The purpose of this research is to find out whether the use of pictures can improve students’ reading comprehension or not. To make the students easily understand about the reading material, teacher needs to have a teaching media. Then, the writer chooses visual media that is picture to increase students’ reading mastery. Pictures are considered as the best media in teaching reading because using picture as a teaching media are able to give the students a clear illustration regarding the correlated topics in texts, tell the students what is going on, and what are the persons in the text are talking about. Nowadays, the pictures and the technologies are becoming more and more advanced. In this decade, we can already materialize a more advanced picture that added by motion and sounds by using simple applications provided in home personal computer. Moreover, the students now are quite used and interested to apply any high tech media.
Based on the result of discussion, it can be concluded that pictures are theoretically can be a good media to help the students enhancing their reading comprehension. Therefore in this view, it is justifiable to hypothetically conclude that using pictures for strengthening students’ visual sense can help them to understand a text.

A method is presented for three-dimensional motion posture correction employing Fuzzy kernel estimation and affine transformation. As selecting human moving node by a visual sensor and smoothing single frame image with irregular motion, noise interference is reduced. Based on principles of perspective and affine transformation, adjustment strategy of three-dimensional posture is deduced for irregular single-frame motion picture. In addition to determination of motion picture rotation, accurate correction of irregular single-frame motion picture is proposed. Experimental results show that, under different noise conditions, the algorithm corrects posture of a three-dimensional moving image accurately and presents strong anti-noise performance.

Full textAbstract:
Methods of assessing presence, a sense of ‘being there’ within a displayed virtual environment, include post-test subjective measures, discrimination tests, and monitoring reflexive responses. Each is limited—either they do not provide a measure of temporal variation, are not feasible with current display technology or are overly content-specific. A measure of presence derived from the method of continuous evaluation (ITU-R, Recommendation BT.500-7, revised, “Methodology for the subjective assessment of the quality of television pictures”, 1995) has been used to overcome these limitations. The results of two experiments are presented. Those of the first experiment established that the methodology is usable under the optimal viewing conditions for the 20 inch stereoscopic TV display upon which our stimuli were presented. It compares within-subject variation on continuous TV picture quality ratings under two viewing conditions—at six picture heights in the light (standard for quality evaluations) and at two picture heights in the dark (optimal stereo TV viewing). The second experiment investigated the effects of manipulations of the visual parameters of stereo, scene motion, and observer-based motion on participants' presence evaluations within edited sections of a stereoscopic film. The results provide support for theories predicting that the extent of sensory information available to a participant is one of the factors determining presence.

Feynman stated that the double-slit experiment “…has in it the heart of quantum mechanics. In reality, it contains the only mystery” and that “nobody can give you a deeper explanation of this phenomenon than I have given; that is, a description of it” [Feynman R, Leighton R, Sands M (1965) The Feynman Lectures on Physics]. We rise to the challenge with an alternative to the wave function-centered interpretations: instead of a quantum wave passing through both slits, we have a localized particle with nonlocal interactions with the other slit. Key to this explanation is dynamical nonlocality, which naturally appears in the Heisenberg picture as nonlocal equations of motion. This insight led us to develop an approach to quantum mechanics which relies on pre- and postselection, weak measurements, deterministic, and modular variables. We consider those properties of a single particle that are deterministic to be primal. The Heisenberg picture allows us to specify the most complete enumeration of such deterministic properties in contrast to the Schrödinger wave function, which remains an ensemble property. We exercise this approach by analyzing a version of the double-slit experiment augmented with postselection, showing that only it and not the wave function approach can be accommodated within a time-symmetric interpretation, where interference appears even when the particle is localized. Although the Heisenberg and Schrödinger pictures are equivalent formulations, nevertheless, the framework presented here has led to insights, intuitions, and experiments that were missed from the old perspective.

This article is an attempt to reflect on Poles' attitude towards the Russian language. Its aim is to reconstruct various “Polish views of Russian” in their objective dimension (with no intention to evaluate or criticise). Three stereotypical pictures of the Russian language present in the Polish common consciousness recreated by the author are based on range of language material. The description of “the three pictures of Russian in the Polish head” (“Polish common knowledge about Russian”) indicates the instrumentality of this language, which occurs in three hypostases. For the first image it is the usual instrumentality of communication (rossicum is an addition and an excess of information within a Polish text), for the second image the instrumentality acquires unambiguously pragmatic features and the rossicum becomes an instrument of effective action, and for the third picture the instrumentality of Russian elements sets in motion the symbolic-cognitive (creating a sense) function of Russian in Polish text.

Full textAbstract:
Although local Hamiltonians exhibit local time dynamics, this locality is not explicit in the Schrödinger picture in the sense that the wavefunction amplitudes do not obey a local equation of motion. We show that geometric locality can be achieved explicitly in the equations of motion by "gauging" the global unitary invariance of quantum mechanics into a local gauge invariance. That is, expectation values ⟨ψ|A|ψ⟩ are invariant under a global unitary transformation acting on the wavefunction |ψ⟩→U|ψ⟩ and operators A→UAU†, and we show that it is possible to gauge this global invariance into a local gauge invariance. To do this, we replace the wavefunction with a collection of local wavefunctions |ψJ⟩, one for each patch of space J. The collection of spatial patches is chosen to cover the space; e.g. we could choose the patches to be single qubits or nearest-neighbor sites on a lattice. Local wavefunctions associated with neighboring pairs of spatial patches I and J are related to each other by dynamical unitary transformations UIJ. The local wavefunctions are local in the sense that their dynamics are local. That is, the equations of motion for the local wavefunctions |ψJ⟩ and connections UIJ are explicitly local in space and only depend on nearby Hamiltonian terms. (The local wavefunctions are many-body wavefunctions and have the same Hilbert space dimension as the usual wavefunction.) We call this picture of quantum dynamics the gauge picture since it exhibits a local gauge invariance. The local dynamics of a single spatial patch is related to the interaction picture, where the interaction Hamiltonian consists of only nearby Hamiltonian terms. We can also generalize the explicit locality to include locality in local charge and energy densities.

Full textAbstract:
A camera sensor may be a useful tool for a number of robotic and autonomous systems when used with MATLAB Simulink for obstacle avoidance. Using a camera sensor and MATLAB Simulink's optical flow algorithm, the obstacle avoidance system is shown in this work. For the purpose of identifying and following the motion of objects in the picture, the system analyses visual data from the camera. The motion vectors of the objects are computed using the optical flow technique, and the robot and obstacles' relative motion is calculated using those motion vectors. In order to provide safe and easy navigation, the system can recognise and avoid obstacles in real-time. The system is easily adjustable and adaptable to diverse applications thanks to the usage of MATLAB Simulink, which enables the integration of several sensor and control systems. The suggested system's findings demonstrate that using a camera sensor with the optical flow algorithm may be a useful tool for obstacle avoidance in a range of robotic and autonomous systems.

Full textAbstract:
This thesis aims to explore how narrative films that are marked by crucial obscurities and explanatory gaps in their development manage to become coherent. More specifically, the thesis is interested in examining how these obscurities and explanatory gaps can be understood as meaningful aspects of the films' organisation. Since the function of coherence in film has rarely been examined directly, the thesis first attempts to illuminate it by drawing on the work of two aestheticians who have examined it more systematically. Thus, the first part of the thesis discusses the work of Victor F. Perkins and George Wilson, while attempting to explore aspects of the work of these two aestheticians through the analysis of specific films. The writings of Perkins and Wilson provide a good starting point for the thesis because they raise crucial questions regarding the ways through which narrative films manage to deal with significant tensions in their organisation and intelligibility. The main body of the thesis (the second part of the thesis) then examines four narrative films, each of which is marked by a significant aspect of apparent incoherence. In each case, the thesis attempts to show that this aspect of apparent incoherence - rather than merely obstructing the film's intelligibility - essentially contributes to the creation of the film's idiosyncratic internal logic. In order to understand how this becomes possible, the thesis pays close attention to the ways in which the various components of each examined film relate to each other, observing and analysing the aesthetic strategies which enable each examined film ultimately to come together.

Full textAbstract:
Indiana University-Purdue University Indianapolis (IUPUI)Physicians were interviewed and asked about their perspectives on communicating with patients, media, and the ways in which the biomedical and biopsychosocial models function in the practice of medicine. Fisher’s Narrative Paradigm was the primary critical method applied to themes that emerged from the interviews. Those emergent themes included the importance of a team approach to patient care; perspectives on physicians as bad communicators; and successful communication strategies when talking to patients. Physicians rely on nurses and other support staff, but the most important partnership is that between the physician and patient. Narrative fidelity and probability are satisfied by strategies physicians use in communicating with patients: using understandable language when talking to patients; engaging in nonverbal tactics of sitting down with patients, making eye contact with patients, and making appropriate physical contact with them in the form of a handshake or a light touch on the arm. Physicians are frustrated by media’s reporting of preliminary study results that omit details as well as media’s fostering of expectations for quick diagnostic processes and magical cures within the public. Furthermore, physicians see the biomedical and biopsychosocial models becoming increasingly interdependent in the practice of medicine, which carries the story of contemporary medicine further into the realm of partnership, revealing its humanity as well as its fading paternalism.

Full textAbstract:
This chapter describes David Cronenberg's use of step-printed slow motion in Shivers (1975). The process entails a loss in image quality — rephotographed by an optical printer, the frames gain grain — and results in a staccato motion quite different from the smooth progression achieved by shooting at high frame-rates. It is a technique which prevents viewer immersion; where conventional slow motion creates the feeling of a dream or altered consciousness, step printing foregrounds the mechanical nature of motion pictures, rupturing the illusions of continuous motion and transparency upon which the illusionist cinema depends. The chapter then studies how Cronenberg builds the eerie sense of emotional displacement in some of the film's scenes. It also considers the staging of rape scenes in Shivers.

Ernie Gehr has worked in both film and digital media. This chapter examines several key works representative of both media. In contrast to critical approaches that see Gehr’s work as purely cognitive or structural exercises, the author argues that it has a deeply personal dimension, the sources of which can be traced to his childhood, and even earlier, to his parents’ experiences during the Second World War. Gehr’s incorrigible sense of play and fascination with magic are explored as essential to his love affair with motion picture media. His use of the frame in both media is particularly stressed as having a strong psychic function, not unlike that of the holding environment provided in psychoanalytic therapy.

Despite the range of ethnicities and nationalities that Brynner played during his career, his roles – from Russian and German military officers to Cossacks, ‘Cajun’ gunslingers, Polish-Japanese American sea rescuers, and Arab and Indian freedom fighters – were largely variations of a type. Typecasting was both an external constraint and a plan of action that he knowingly operated with by repeatedly taking on roles of ‘bastards with a heart of gold’. Exploring Brynner’s roles in the context of the racial dynamics of Hollywood’s Motion Picture Production Code, this chapter makes sense of his roles extending from yellowface to brownface and redface in accented English. Addressing Brynner’s characters’ introduction scenes in particular, as well as the reception films’ reception, it inquires after recurrent elements in his performance style.

Abstract Much of the history of physics has been characterized by the effort to understand, in great detail, increasingly smaller pieces of nature; beginning with classical particles and waves, and progressing to molecules, atoms, nuclei, and elementary particles. This trend became especially pronounced in the twentieth century with the development of sophisticated experi mental apparatus capable of probing deeply into nature’s innermost parts. Aside from the sense that one is closer to reality at the deeper levels of nature, it is plausible to assume that a clear understanding of the small pieces of nature will lead to a clear view of the large picture. The whole is presumed equal to the sum of its parts. This approach is sometimes call reductionism. More recently, in certain areas of physics, the opposite methodology has proved fruitful. New structure and organization may become evident when there is complexity, large numbers of parts, several degrees of freedom, or even just sufficient energy to make a discrete change in the system. Indeed, sometimes the whole is more than the sum of its parts. This creation of new richness of behavior often occurs in the study of processes that are pushed well beyond their equilibrium configurations. Researchers find new levels of organization, new complexity that does not seem to be obvious from a consideration of the individual parts of the process (Prigogine 1980). For example, if reactants are forced rapidly into certain chemical reactions, the resultant products may show spatial or temporal ordering (Zhabotinskii 1991). Or convective systems with large temperature gradients may exhibit new structural or dynamic organization of fluid motion. Even the motion of the humble pendulum achieves a new level of complexity if it is driven energetically at nonresonant frequencies.

Abstract Many of The Litigations and other matters that presented legal aspects were also economic matters. It always seemed to me that the President was at his weakest in dealing with economic or business problems. He had not engaged in business as my law practice had compelled me to do, and he had no personal knowledge of its methods or its problems. He tended to think of economic matters as personal rather than impersonal forces. He was much inclined to think about economic matters in terms of rights and wrongs. He was inclined to think that we were prosecuting a group of businessmen because they had done some moral wrong, and that if he talked to them and made them see that their course was morally wrong, they would do something about it. When we were considering the commencement of Department of Justice actions in 1937 to dissolve the motion picture combines, I went to the President and told him that I wanted to start an action against them. The President said, “Well now, of course, they’ve been doing wrong, but do you really need to sue these men? If you would bring them in here and let me talk with those fellows, don’t you think they would change their practices? I think they can be straightened out.” My answer, of course, was that these men were in a sense victims of their practices as well as perpetrators of them. It was a system that had grown up to where no one man or group could break it up without the intervention of government. Even if they all decided they ought to break it up, they could not do it. It was not a moral problem. It was not a right and wrong problem. It was a social and antisocial problem that did not reach moral concepts. What the President found difficult to envision was that they were caught up in a course of business practices that they were as powerless to escape from individually as if they were prisoners.

Full textAbstract:
The nervous system is an integrating system which acts rapidly by transmitting signals as electrical impulses over often considerable distances to coordinate bodily activities. The brain and spinal cord make up the central nervous system (CNS); incoming information travels in ascending (sensory) tracts that link the spinal cord to the brain and outgoing information passes down descending (motor) tracts linking the brain to the spinal cord. The CNS integrates responses to incoming information and sends the information to effector tissues (usually striated or smooth muscles or glands). Incoming and outgoing information is carried to and from the periphery to the CNS via 12 pairs of cranial nerves connected to the brain and 31 pairs of spinal nerves connected to the spinal cord; they constitute the peripheral nervous system (PNS). Sensory (afferent) information from the external environment is obtained through the organs of special sense in the eyes, ears, nose and tongue, and skin and mucosa lining bodily cavities: we are aware of these stimuli. Information from internal sources is equally important and vital for maintaining homeostasis, but we are usually Neurons are the basic cellular units of the nervous system. As the principal function of the nervous system is conduction of electrical signals over considerable distances, neurons are highly specialized for this f unction. Neurons have: • A specific shape with long cellular extensions; • Highly specialized membranes to control ionic movements to allow electrical activity to spread along the cellular extensions; • A very specialized internal transport system to distribute cellular metabolites along the processes. The general shape of neurons is shown in Figure 3.1. Note first of all, the relatively large cell body near the top of the picture; this contains the nucleus and the intracellular organelles necessary for synthetic functions so is similar to any other cell. What make neurons special are the long processes that emanate from the cell body. Dendrites are short multiple processes that branch extensively from and transmit impulses towards the cell body. Compare the dendrites in Figure 3.1 with the other process, the axon, which transmits impulses away from the cell body.

The image is one of the most suitable information input representations for future multimedia systems. However, it is difficult for conventional charge coupled device (CCD) systems to handle such image information, especially in high speed image processing such as motion picture processing. This is caused by the limitation of the frame rate of the CCD (1/60-1/30sec) and by the bus capacity between the CCD and the computer. To solve the problem of this transmission bottle neck, we have proposed a novel type of image sensor, an artificial retina (AR) chip, and we have demonstrated flexible and high-speed on-chip processing capabilities of the chip [1].

This work presents an experimental study focused on a challenging signal interpretation issue arising in using wireless tri-axial sensors to measure acceleration components in rotating flexible rotor systems. Experiments with state of-the-art (modern technology microsystems) wireless accelerometers reveal that the dynamics of a rotating and-at the same time torsionally vibrating-flexible rotor system is perceived by the rotating sensor as a fast amplitude modulation of a slowly varying vibration. It is observed that the typical signal furnished by the rotating sensor consists of two distinct zones of harmonics: one is a broad band low frequency zone and is associated with the rigid body rotational motion, whereas the other zone contains distinct higher frequencies associated with torsional vibrations. The interesting result is the fact that in the frequency domain the fast torsional vibrations can be extracted sharply from the overall sensor signal. This is due to fact that the dynamics of the sensor output are characterized by slow and fast time scales. It turns out that the high harmonics of the rotating-and-vibrating system (generic motion) are very close to those of the non-rotating-but-torsionally vibrating system. A definite answer to a physics interpretation of the typical output of a rotating accelerometer (oscillator-based) is established by modeling the whole flexible rotor-sensor system as a singular perturbation coupled oscillators problem. This geometric mechanics modeling-analysis approach presents a global picture of the acceleration sensing property of stiff linear oscillators attached on rotating structures.

The production metrology of today is still dominated by tactile probing systems. However some special metrological tasks cannot be fulfilled by this technique, one example is in the high precision manufacturing of surfaces and structures, which become ultra-miniaturized, complex and fragile. The inspection of small boreholes and cavities is also an example with very tight tolerances which demands non-contact miniaturized sensors. Particularly the measurement of the shape of spray holes in modern fuel injection nozzles for diesel engines fits this statement, as its shape represents the key factor for maximal motor efficiency, as well as minimal pollutant emissions. Any deviation from its design shape significantly affects spray breakup and can lead to unequal distribution of flow and pressure changes. These holes can have diameter of 150 microns, with a tendency to even smaller diameters in future systems. Within this work the integration of a fiber optic sensor for distance measurements in measuring machines, specifically for borehole inspection, is described. The used device is a form-tester (Mahr GmbH, MMQ-400) with 3 degrees of freedom. The motion of the machine axis will be controlled with help of image processing operation which are based on pictures taken from the specimen’s top surface. For this mean a micro camera will be mounted on the form-tester. By applying in-house developed MATLAB codes, the exact position of the boreholes and that of the fiber optic probe is obtained, so that an automated positioning and measurement (e.g. round-out and roundness tests) could be performed. This process enhances both the precision due to an optimized sensor positioning and speed of the measurement rather than manual execution. Different positioning scenarios will be discussed and compared in this paper, to prove the capability of the proposed system as well as its adaptivity.

This study emphasizes the way Polar Team Pro technical solution is being implemented in competitive football training process, in terms of evaluation and monitoring the official games' parameters of football teams. This ultimate wearable technology allows tracking everyone's performance in the team, in real time, throughout the whole season. Informative reports using different filtering and search criteria are available for the coaching staff, so that a comprehensive image can be revealed about the team as a whole, and about each player performance, according to his position. The continuous flow of information provides an accurate picture of the team evolution during official games, on different components related to a successful performance. The functional, spatial and motor -related parameters, such as GPS player's positioning, speed and distances covered, distances within individual speed zones, accelerations, number of sprints and running speeds, along with heart rate monitoring are recorded by means of a Polar Team Pro sensor (which collects data about heart rate and movements tracked by GPS), a Polar Team Pro web service (cloud-based tracking system) and a Polar Team Pro app (monitoring real-time data, comparing players performance, getting game summaries etc). The individual and team data are stored in a Cloud system, allowing creating athletes profiles, team dynamics and diagnosis of performance level. This paper focuses on revealing a way of using a data base, by means of the Polar Team Pro technology, as a starting point to conceiving training guidelines, for different age groups or/and position of the players, within the team.

Archaeological documentation is a complex process where the technical measurement and specification of colour is a key aspect. In the last years heritage documentation processes have largely benefited from the application of digital recording methods, imagery analysis software and technologies that offers great advantages over the traditional methods. The rigorous processing of colourimetric data requires software packages with specific colourimetric technical characteristics. In this paper we report on our in-house pyColourimetry software that was developed and tested taking into account the recommendations of the Commission Internationale de l'Éclairage (CIE). The objective is to apply a rigorous procedure for the characterisation of cameras based a priori on polynomial models. Most of the digital cameras capture colour information in the well-known RGB format, but the signals generated by the digital camera are device dependent. By means of the characterisation we establish the relationship between device dependent RGB values and the tristimulus coordinates defined by the CIE standard colourimetric observer. Once the camera is characterised, users have the potential to obtain output images in the sRGB space that is independent of the sensor of the camera. pyColourimetry software allows users to control the entire digital image processing and the colourimetric data workflow proposed. We applied the methodology on a set of pictures targeting Levantine rock art motifs in Cova dels Cavalls (Castellón, Spain) which is considered part of a UNESCO World Heritage Site. The outcomes obtained are satisfactory and very promising for proper colour documentation in cultural heritage estudies.http://dx.doi.org/10.4995/CIGeo2017.2017.6568

Friction tests under controlled conditions are crucial for the understanding of the boundary layer dynamics in technical brake systems. The dynamics of the friction interface characterize the braking performance, which has to be evaluated and monitored in the early stages and throughout the development process of new friction materials. For this purpose, detailed insights into the friction behavior is obtained by high precision tribotesters under laboratory conditions. Especially in the low sliding speed range, specialized machines such as the Variable Velocity Tribotester (VVT) make it possible to mimic real world phenomena under controlled conditions, e.g. creep groan or COF in low temperatures. The VVT is modularly designed with two linear stages to move the test specimen and a highly capable servor motor for the rotation of the brake disc. A rotational disk speed of up to 400 rpm is reached with a resolution of 25 bit and a 1:10 gearbox. The normal load can reach up to 300 N (approx. 45 bar brake line pressure) by utilizing a leaf spring load unit. A 3-axis piezoelectric force sensor directly at the test specimen measures the applied and resulting forces.</p><p>In addition to the friction testing, it is possible to automatically move the specimen to a high precision 3D laser scanning device with stripe light projection and to record height information and pictures of the friction surface. For measurements below room temperature, the VVT is located in an insulated chamber and equipped with two cooling aggregates

In the event of sodium leakage from heat transfer circuits of fast breeder reactors (FBR), liquid sodium catches fire in ambient air leading to production of flame, smoke and heat. One of the passive fire protection methods involves immediate collection of the leaking sodium to a sodium hold-up vessel (SHV) covered with a sloping cover tray (SCT) having a few drain pipes and one vent pipe (as in Fig. 1). As soon as the liquid sodium falls on the sloping cover tray, gravity guides the sodium through drain pipes into the bottom tray in which self-extinction occurs due to oxygen starvation. This sodium fire protection equipment called leak collection tray (LCT) works without the intervention of an operator and external power source. A large number of LCTs are strategically arranged under the sodium circulating pipe lines in the FBR plants to serve as passive suppression devices. In order to test the efficacy of the LCT, four tests were conducted. Two tests were with LCT having three drain pipes and rest with one. In each experiment, nearly 40 kg of hot liquid sodium at 550 °C was discharged on the LCT in the open air. Continuous on-line monitoring of temperature at strategic locations (∼ 28 points) were carried out. Colour videography was employed for taking motion pictures of various time-dependent events like sodium dumping, appearance of flame and release of smoke through vent pipes. After self-extinction of sodium fire, the LCT was allowed to cool overnight in an argon atmosphere. Solid samples of sodium debris in the SCT and SHV were collected by manual core drilling machine. The samples were subjected to chemical analysis for determination of unburnt and burnt sodium. The results of the four tests revealed an interesting feature: LCT with three drain pipes showed far lower sodium collection efficiency and much higher sodium combustion than that with just one drain pipe. Thermal fluctuations in temperature sensor located near the tip of the drain pipe have indicated that transient freezing and remelting processes are responsible for this phenomenon. Moreover comparison of test results between present and earlier experiments has revealed that the LCT with funnel shaped SCT is superior to that with boat shaped SCT.
