La grille et la palme. Deux régimes d’exportation des biens audiovisuels

En comparant deux des principaux marchés audiovisuels internationaux, le MIF et le MIPTV, chacun situé à Cannes, on montre d’abord qu’ils sont des lieux d’évaluation et de valorisation des biens audiovisuels à exporter plus que des lieux de fixation des prix. Ils obéissent moins à la définition néoclassique du marché qu’à celle d’une sociologie économique attentive aux formes de « métrologies » marchandes. Ils n’en constituent pas moins des lieux d’observation privilégiés des régimes de valorisation des biens audiovisuels dans le commerce international. On montre en outre que ces régimes diffèrent beaucoup pour les exportateurs français qui ont été enquêtés. Le MIPTV obéit à un « régime d’exposition », où il s’agit de présenter le maximum de programmes audiovisuels pour les transférer d’une « grille » de programmation à une autre. Le MIF relève d’un « régime festif » où les biens sont mis aux enchères, le festival – et sa « palme » – étant le dispositif central du marché auquel il donne son rythme.

A Proposed Investment on a University Campus

College days are probably the most memorable years of a man or woman’s life. The students’ unions’ associations and entertainment building usually houses rooms for meetings and seminars, a book store, a small grocery store, a novelty store, a number of brand name fast and regular food restaurants, an arcade for games machines, bowling, ping pong, billiards, and a large space with appropriate seating for students and guests, and large screen TV’s and a movies theater. This paper proposes a scheme to build a risk managed students association building dedicated to the satisfaction of campus’ students’ and visitors’ needs. The return on its operations is assumed to be very rewarding to entrepreneurs and small businesses alike. This paper presents a case in which a union building is budgeted, three legal businesses leasing spaces within this building. The building’s budgeted capital is financed. The space leased by the three businesses represents a small percentage of the overall structure, however, its revenue and specifically input into the building’s investment is relatively much larger, emphasizing that the union’s building’s investment is a successful venture. An element of humorous sarcasm is introduced in describing one of the union building’s leasing businesses; a provision of an entertaining flavor to escort readers’ attention.

Besides the excellent mechanical properties compared with PMMA, improved brightness and small chromaticity difference will provide new possibility, such as to realize the perfect “zero‐bezel”, one of the ultimate TV designed.

Throughput-Efficient Channel Allocation Algorithms in Multi-Channel Cognitive Vehicular Networks

Many studies show that the dedicated short range communication band allocated to vehicular communications is insufficient to carry the wireless traffic generated by emerging vehicular applications. A promising bandwidth expansion possibility presents itself through the release of large TV band spectra (i.e., the TV white space spectrum) by the Federal Communications Commission for cognitive access. One primary challenge of the so-called TV white space (TVWS) spectrum access in vehicular networks is the design of efficient channel allocation mechanisms in face of spatial-temporal variations of TVWS channels. In this paper, we address the channel allocation problem for multi-channel cognitive vehicular networks with the objective of system-wide throughput maximization. We show that the problem is an NP-hard non-linear integer programming problem, to which we present three efficient algorithms. We first propose a probabilistic polynomial-time (1-1/e)-approximation algorithm based on linear programming. Next, we prove that the objective function can be written as a submodular set function, based on which we develop a deterministic constant-factor approximation algorithm with a more favorable time complexity. Then, we further modify the second algorithm to improve its approximation ratio without increasing its time complexity. Finally, we show the efficacy of our algorithms through numerical examples.

Experimental study for the establishment of an evaluation criterion for the image sticking effect in OLED TV panels

AbstractThe individual elements of organic light‐emitting diode (OLED) displays degrade at different rates, because each element emits light independently; the resulting luminance differences between individual elements cause image sticking—a phenomenon where a displayed text or pattern remains on the screen even after changing the image contents—and are therefore an important issue in OLED displays. However, the introduction of OLED technology into large TV displays is still recent, and no criterion for image sticking evaluation has yet been established. The keystone of a criterion for image sticking evaluation is the definition of the difference level between the luminance of individual elements at which the viewer feels that image sticking is present. Therefore, in this study, an image sticking perception experiment is carried out in accordance with statistically sound procedures for experimental design, using a comprehensive set of human subjects to evaluate the presence of image sticking in moving images. The obtained results are analyzed, and two criteria for image sticking evaluation are proposed.

Measuring social integration among residents in a dementia special care unit versus traditional nursing home: A pilot study.

The physical and mental health of older adults with dementia is affected by levels of social integration. The development of dementia special care units (D-SCU) arose, in part, to facilitate more meaningful social interactions among residents implying greater social integration of D-SCU residents as compared to residents in a traditional nursing home (TNH). But, it is unknown whether D-SCU residents are receiving equal or greater benefits from living on a segregated unit intended to enhance their social environment and integration through both design and staff involvement. The purpose of this study was to pilot test a comprehensive objective assessment to measure social integration among nursing home residents with dementia and to compare levels of integration of residents living on a D-SCU to those living in a TNH. A total of 29 residents participated (15 D-SCU and 14 TNH) and data were gathered from medical charts, visitor logs, and through direct observations. Over 1700 interactions were recorded during 143 h of observation. Specifically, the location, context, type, quantity, and quality of residents' interactions were recorded. Overall, the majority of resident interactions were verbal and initiated by staff. Interactions were social in context, and occurred in public areas, such as the common room with a large screen TV. Average interactions lasted less than 1 min and did not change the resident's affect. Residents spent between 10% and 17% of their time interacting with other people on average. D-SCU staff were significantly more likely to initiate interactions with residents than TNH staff. D-SCU residents also experienced more interactions in the afternoons and expressed more pleasure and anxiety than residents in the TNH. This study helps to lay the groundwork necessary to comprehensively and objectively measure social integration among people with dementia in order to evaluate care environments.

Development of cooling technologies for SMES

A Superconducting Magnetic Energy Storage (SMES) system has good characteristics as energy storage equipment in electric power systems such as high efficiency, quick response and no deterioration in repetition operation. Since 1991, the Agency for National Resources and Energy Japan has carried out a national project to develop an SMES for power control in power systems. Moreover, SMES has been developed to bridge for instantaneous voltage dips since 2003. A field test of 5MVA SMES for bridging instantaneous voltage dips was carried out on an advanced large liquid crystal TV plant in Kameyama from July 2003. Before that, a 10MVA SMES system was working there. After the field test, the commercial SMES for instantaneous voltage dips is working there. In 2015, three commercial SMES units for bridging instantaneous voltage dips are operating in Japan. These SMESs are all equipped with metal superconducting coils. When considering cost-reduction, size-reduction, and maintenance of the SMES in the future, it is necessary to develop a SMES with a high-temperature superconductor and improve the efficiency of its cooling system. We have also developed and conducted operation tests of SMES with a Bi2212 oxide superconductor and high performance cryocooler which enable energy conservation operation by inverter control. In this paper, developed results on cooling systems and cryocooler for SMES are presented.

ПРАКТИКИ ИССЛЕДОВАНИЯ АУДИТОРИИ В ВЕДУЩИХ РОССИЙСКИХ ТЕЛЕКОМПАНИЯХ

The paper covers the modern practices of application of the audience measurements results within large Russian TV channels. The audience measurements are the important source of parameters for mass media performance evaluation. They got traction in all segments of mass information, among which television is the most popular, effective from the point of view of impact and affecting the wide range of target groups. The goal of the research presented by the author in this paper is the study of one of the elements of television company performance – media measurement based on the practices of the audience research in the leading Russian TV companies. To implement the target goal, the author carries out the in-depth interviews with the heads of the audience research departments within Russian TV channels. The in-depth interviews touched upon such subjects as the structure of the audience inner analysis department, types of research carried out or ordered by a television company, the department staff duties, the influence of obtained data on a TV channel viewing grid, and the special aspects of obtaining media-measurements in the regions. The author analyzes and summarizes the obtained data, considers the main directions of the research results application in the TV channels activity, which are the important integral part when studying the whole media-measuring field. The author is the first who attempts to study the audience analysis practices within media companies basing on the experience of the audience measuring departments within Russian television channels. Based on the results of the research, the author determined such problems as the insufficient knowledge of audience in the regions, the limitation of research activity of many channels only by the “TNS Russia” data secondary analysis. The author specifies the differences in the research activity and the application of media measurement data within commercial and state television channels.

Navigating News Programs in Large TV-Streams

The different uses of large TV streams have continued to diversify since the appearance of digital TV. For conveniently retrieving and navigating in TV streams, users are often interested in new content-based multimedia applications of high added value such as Interactive TV, Video on Demand (VoD), YouTube or Dailymotion. These applications offer fast and easy access to best explore a particular TV program. So, the automatic process of TV program identification and their internal segmentation facilitate the availability of these programs. Therefore, it is necessary at first, to be able to retrieve a particular program within a large TV stream and secondly segment this program into semantic units related to appropriate retrieval entities. In this paper, the major originality of the authors' approach is the use of contextual and operational characteristics of TV production/post-production rules as prior knowledge that captures the structure for recurrent TV news program content. The authors validate their approach by experiments conducted using the TRECVID dataset that demonstrate its robustness.

Handheld Visual Representation of a Castle Chapel Ruin

We have experienced rapid development in Augmented Reality (AR) systems and platforms in the world of cultural heritage, namely in cultural settings and historical museums. However, we still face a range of challenges to design an AR system that meets the requirements for an AR installation working autonomously in a cultural heritage setting for an extended duration. This article describes the development of two installations for the visualization of a 3D reconstruction of a castle chapel, running autonomously during open hours in the location of a castle museum. We present a convincing 3D visualization running at interactive frame-rates on modern tablets. In one installation, the tablet is connected to a large screen TV for an immersive experience, and, in another, the tablet is hand-held, thus facilitating translational freedom in the chapel. Both installations allow unsupervised usage during museum visiting hours. Based on in-field observations and on-device logging of application usage, user behavior is analyzed and evaluated. Results indicate that users spent a limited amount of time using the application and did not fully explore the visual area of the chapel. In order for the user to spend more time with the application, additional information must be presented to the user.

From The Office to Stromberg: adaptation strategies in German television

Stromberg (2004–2012) was one of the most successful sitcoms on German television. It was based on the British ‘mockumentary’ The Office (2001–2003). The format can serve as an example how German TV adapts foreign formats and adjusts them to the local market. Even though Germany is the largest TV market in Europe, it has always been an importer of television programming, and it imports more formats in the fiction and entertainment segment than it exports. The British and US TV markets are the main resources for German television. There is a long tradition of licensing and adapting British and US formats, going back to the 1960s. In a certain way British comedy programs were successful, because a relevant part of German audiences love what they call ‘black British humour’. Whereas in the past most of the programs were licensed and dubbed, there are some adaptations where formats like The Office or Till Death Us Do Part were localized for German audiences. British humour and style were adjusted in a way that Germans would be able to appreciate that kind of program. Through this process, The Office mockumentary became Stromberg, a classical sitcom for German television.

Now, small to medium size OLED displays have already been commercialized. Large OLED TVs and OLED lightings have also emerged in real applications. The further development of the OLED technology calls for intensive research on organic light-emitting materials and devices. This report reviewed the most focused issues as well as the main progress in the field of OLEDs in the recent years. It is shown that researchers have paid attentions to both technical innovations and theoretical researches, such as the design of new molecules, developing of new device technology, and understanding of light-emitting and transporting mechanisms of organic semiconductors.The developing trends of organic light-emitting materials and devices are summarized as follows: 1) molecular design for high performance phosphorescent materials; 2) novel fluorescent materials and their light emitting mechanisms; 3) new technologies for high performance white OLEDs; 4) new technologies for solution-processed devices and flexible devices; 5) the influences of molecular packing, disorder and doping on the charge transporting properties of organic semiconductors. Moreover, the current situations and developing trends of international OLED display and lighting industries are discussed.

A roadshow of library resources: familiarize students with what you have

Purpose – The purpose of this paper is to describe how the popular culture of flash mob inspired the creation of the library roadshows and elaborate on the conducting of flash outreach events to market music databases to students with limited resources. Design/methodology/approach – By not requesting faculty for in-class teaching time, the promotion of library e-resources took place beyond the library building, in places where students live and hangout, and during the short window when students mingle before classes. Simple set-up with laptops and a movable large screen TV was used for brief database demonstration. Findings – The provision of quick demos and on-the-go consultations of e-resources through the library roadshows proved to encourage usage and obtain a higher return on investment without requiring much extra manpower and funding. Students also welcomed this new way of learning without having to go to a class. Social implications – Seeing students and offering services where students live and hangout help make the library more visible and blend librarians in students’ campus life. Originality/value – While information literacy workshops oftentimes happen inside the library or during a class hour, the library roadshows go beyond physical boundaries and take information literacy instruction to where the targeted audience is. Not only are these flash outreach events quick and easy to conduct, but this casual learning also fits the learning behavior of the millennial generation who wants everything succinct and straight to the point.

Peritoneal Dialysis is Limited by Kidney and Liver Volume in Autosomal Dominant Polycystic Kidney Disease.

We evaluated the influence of kidney volume (KV) and liver volume (LV) on continuation of peritoneal dialysis (PD) in patients with autosomal dominant polycystic kidney disease (PKD). Twenty-two PKD patients on PD were retrospectively investigated after being divided into two groups. Group 1 comprised 15 patients who started PD at our hospital and group 2 was composed of seven patients referred from other hospitals for treatment of renomegaly by transcatheter arterial embolization (TAE) at 47.1 ± 21.8 months after commencing PD. In group 1, KV for both kidneys (mean ± SD) was 2787 ± 1945 mL (range: 1043 to 6816 mL), LV was 2198 ± 1139 mL (1005 to 4116 mL), and the total organ volume (TV=KV+LV) was 4985 ± 1815 mL (2320 to 8912 mL). In the patient with the largest TV from group 1 (KV of 6816 mL, TV of 8912 mL, and TV/BMI ratio of 426, PD was stopped due to dialysate leakage. However, dialysate leakage did not occur in the other 14 patients (TV ≦ 7963 mL and TV/BMI ratio of 353 at the start of PD). In group 2, KV was 5822 ± 1597 mL (3832 to 8862 mL), LV was 1776 ± 519 mL (1271 to 2671 mL), and TV was 7597 ± 1431 mL (5505 to 10358) before TAE. Leakage of dialysate did not occur with a mean infusion volume of 1530 ± 370 mL (1000 mL to 2000 mL), even after renomegaly and hepatomegaly progressed to the maximum TV/BMI ratio of 359. Six patients from the two groups developed new abdominal hernias at 36 ± 5 months (6-55 months) after starting PD. These findings suggest that performance of PD may be limited by renomegaly and hepatomegaly in patients with PKD.

3D Holographic Animation of Modern Mechanical Watch Escapements

ABSTRACTIn the past 100 years, nearly all mechanical watches used a same escapement, called the Swiss lever escapement. In the past two decades, though, a couple of new escapements are invented, including the Girard-Perregaux Constant Force Escapement and the Dual Ulysse Escapement. Set aside to design and make these escapements, it is difficult to describe the movements of these complex escapements. In this paper, we use a simple pseudo 3D holography system to show the movements of these two escapements. This low-cost system can be used with a smartphone for display on site or used with a large screen TV for display in shops. It adds a new way to demonstrate the movements of complex mechanical watches and other mechanical devices.

Exact Support Recovery for Sparse Spikes Deconvolution

This paper studies sparse spikes deconvolution over the space of measures. We focus on the recovery properties of the support of the measure (i.e., the location of the Dirac masses) using total variation of measures (TV) regularization. This regularization is the natural extension of the $$\ell ^1$$ norm of vectors to the setting of measures. We show that support identification is governed by a specific solution of the dual problem (a so-called dual certificate) having minimum $$L^2$$ norm. Our main result shows that if this certificate is non-degenerate (see the definition below), when the signal-to-noise ratio is large enough TV regularization recovers the exact same number of Diracs. We show that both the locations and the amplitudes of these Diracs converge toward those of the input measure when the noise drops to zero. Moreover, the non-degeneracy of this certificate can be checked by computing a so-called vanishing derivative pre-certificate. This proxy can be computed in closed form by solving a linear system. Lastly, we draw connections between the support of the recovered measure on a continuous domain and on a discretized grid. We show that when the signal-to-noise level is large enough, and provided the aforementioned dual certificate is non-degenerate, the solution of the discretized problem is supported on pairs of Diracs which are neighbors of the Diracs of the input measure. This gives a precise description of the convergence of the solution of the discretized problem toward the solution of the continuous grid-free problem, as the grid size tends to zero.

Novel Hybrid Content Synchronization Scheme for Augmented Broadcasting Services

As a new hybrid broadcasting service, augmented broadcasting shows enhanced broadcasting content on a large TV screen, while augmented reality (AR) on a mobile device augments additional graphical content onto an input image from the device's own camera to provide useful and convenient information for users. A one-sided broadcasting service using AR has already been attempted in virtual advertisements during sport broadcasts. However, because its augmentation is preprocessed before the video image is transmitted, the viewer at home may have no influence on this formation; and no interaction for the user is possible unless the viewer has a direct connection to the content provider. Augmented broadcasting technology enables viewers to watch mixed broadcasting content only when they want such service and to watch original broadcasting content when they do not. To realize an augmented broadcasting service, the most important issue is to resolve the hybrid content synchronization over heterogeneous broadcast and broadband networks. This paper proposes a novel hybrid content synchronization scheme for an augmented broadcasting service and presents its implementation and results in a terrestrial DTV environment.
