    Fireworks is a CMS event display which is specialized for the physics studies case. This specialization allows us to use a stylized rather than 3D-accurate representation when appropriate. Data handling is greatly simplified by using only reconstructed information and ideal geometry. Fireworks provides an easy-to-use interface which allows a physicist to concentrate only on the data in which he is interested. Data is presented via graphical and textual views. Fireworks is built using the Eve subsystem of the CERN ROOT project and CMS's FWLite project. The FWLite project was part of CMS's recent code redesign which separates data classes into libraries separate from algorithms producing the data and uses ROOT directly for C++ object storage, thereby allowing the data classes to be used directly in ROOT.

    Little is known about the level and content of exposure to fine particles (PM 2.5) among persons who attend fireworks displays and those who live nearby. An evaluation of the levels of PM 2.5 and their elemental content was carried out during the nine launches of the 2007 Montréal International Fireworks Competition. For each event, a prediction of the location of the firework plume was obtained from the Canadian Meteorological Centre (CMC) of the Meteorological Service of Canada. PM 2.5 was measured continuously with a photometer (Sidepak™, TSI) within the predicted plume location ("predicted sites"), and integrated samples were collected using portable personal samplers. An additional sampler was located on a nearby roof ("fixed site"). The elemental composition of the collected PM 2.5 samples from the "predicted sites" was determined using both a non-destructive energy dispersive ED-XRF method and an ICP-MS method with a near-total microwave-assisted acid digestion. The elemental composition of the "fixed site" samples was determined by the ICP-MS with the near-total digestion method. The highest PM 2.5 levels reached nearly 10 000 μg m -3, roughly 1000 times background levels. Elements such as K, Cl, Al, Mg and Ti were markedly higher in plume-exposed filters. This study shows that 1) persons in the plume and in close proximity to the launch site may be exposed to extremely high levels of PM 2.5 for the duration of the display and, 2) that the plume contains specific elements for which little is known of their acute cardio-respiratory toxicity.

  13. Fireworks

    Directory of Open Access Journals (Sweden)

    Kate Flint

    2017-12-01

    Full Text Available Taking as my starting point James McNeill Whistler’s 1875 painting 'Nocturne in Black and Gold: The Falling Rocket', I ask what it meant, in the mid-nineteenth century, to represent fireworks, and how we might interpret Whistler’s canvas in the light of the broad context of pyrotechnic displays and the associations that attended them. The article explores the stylistic and material aspects of the work, using both the remarks of contemporary critics and Theodor Adorno’s comments about fireworks as a means of considering the productive tension between abstraction and representation, movement and stasis. I consider, too, Whistler’s own appeal to affect in this and other nocturnes. I then look at the viewing conditions that surrounded this 'Nocturne'’s early exhibition, and how the difference between the Dudley Gallery and the Grosvenor Gallery may well have meant different spectator expectations when it came to assessing it alongside other works that were on display. I argue that visitors to both galleries, however, would have shared knowledge of firework displays that they had witnessed in person; of descriptions, allusions, and rhetorical inclusions of fireworks in fiction and poetry; and of their depiction in the popular illustrated press. To be sure, Whistler’s paintings of fireworks might make it impossible not to watch future firework displays with his indistinct, yet atmospheric means of capturing moving sparks in mind. But it is misleading to consider these depictions of short-lived, spectacular bursts of fiery colour as self-contained. I maintain that however much the artist might have wished the 'Nocturne' to be an autonomous work for contemplation, associative moves on a viewer’s part — ones that draw on the wide contemporary visual and verbal rhetoric surrounding fireworks — make it impossible to contain the operations of spectatorship.

  5. Recreational atmospheric pollution episodes: Inhalable metalliferous particles from firework displays

    Science.gov (United States)

    Moreno, Teresa; Querol, Xavier; Alastuey, Andrés; Cruz Minguillón, Mari; Pey, Jorge; Rodriguez, Sergio; Vicente Miró, José; Felis, Carles; Gibbons, Wes

    The use of fireworks creates an unusual and distinctive anthropogenic atmospheric pollution event. We report on aerosol samples collected during Las Fallas in Valencia, a 6-day celebration famous for its firework displays, and add comparative data on firework- and bonfire-contaminated atmospheric aerosol samples collected from elsewhere in Spain (Barcelona, L'Alcora, and Borriana) and during the Guy Fawkes celebrations in London. Specific high-profile official firework events during Las Fallas included the afternoon Mascletà and the nightly aerial displays (especially in the climactic final 2 days of the fiesta) and were accompanied by pollution spikes in suspended particles, NO, SO 2, and the creation and dispersal of an aerosol cloud enriched in a range of metallic elements. Notable metal aerosol concentration increases recorded during Las Fallas were potassium (from 500 to 5900 ng m -3), aluminium (as Al 2O 3 from around 600 to 2200 ng m -3), titanium (from 200 to 700 ng m -3), magnesium (from 100 to 500 ng m -3), lead (from 17 to 379 ng m -3), barium (from 39 to 322 ng m -3), strontium (from 3 to 112 ng m -3), copper (from 12 to 71 ng m -3), and antimony (from 1 to 52 ng m -3). Firework-contaminated aerosols of similarly metalliferous composition were also identified at the other monitoring sites, although different sites show variations attributable to other sources such as bonfires and local industry. Unusual levels of the trace elements Ba, Sr and (to a lesser extent) Cu, always in proportions with Ba dominant, along with strongly enhanced K, Pb, and Sb, are identified as being particularly characteristic of firework aerosols. Although firework-related recreational pollution episodes are transient in nature, they are highly concentrated, contribute significantly to total annual metal emissions, and are on average fine enough to be easily inhaled and a health risk to susceptible individuals.

  10. Firework displays as sources of particles similar to gunshot residue.

    Science.gov (United States)

    Grima, Matthew; Butler, Mark; Hanson, Robert; Mohameden, Ahmed

    2012-03-01

    In light of past research being targeted to find specific particles which may be similar to gunshot residue (GSR), this project was formulated to detect any possible particulate by random particle fallout onto substrates at firework displays and to assess the impact this may have on GSR evidence. Firework residue was collected at a display site, from amongst spectators as well as from the author's hair 90min after the display. SEM-EDX analysis has detected such particulate in all three scenarios, with the firework particle population at large providing a solid ground for discrimination from GSR. Wind dispersal was found to decrease the particle population and subsequently, the latter's discriminatory power. Some particles, if treated individually were found to be indistinguishable from GSR. Findings also include residues which may mimic strontium based GSR as well as GSR which may be mixed with that from previous firings. The continuous changes made to primer and propellant compositions by manufacturers also call for greater consideration when classifying particles as originating from pyrotechnic devices. Furthermore, authorities such as police forces should be made more aware about the incidence of such particle transfer in firework related periods. Copyright © 2011 Forensic Science Society.

  14. Hazard Quotients, Hazard Indexes, and Cancer Risks of Toxic Metals in PM10 during Firework Displays

    Directory of Open Access Journals (Sweden)

    Siwatt Pongpiachan

    2018-04-01

    Full Text Available Bonfire night is a worldwide phenomenon given to numerous annual celebrations characterised by bonfires and fireworks. Since Thailand has no national ambient air quality standards for metal particulates, it is important to investigate the impacts of particulate injections on elevations of air pollutants and the ecological health impacts resulting from firework displays. In this investigation, Pb and Ba were considered potential firework tracers because their concentrations were significantly higher during the episode, and lower than/comparable with minimum detection limits during other periods, indicating that their elevated concentrations were principally due to pyrotechnic displays. Pb/Ca, Pb/Al, Pb/Mg, and Pb/Cu can be used to pin-point emissions from firework displays. Air mass backward trajectories (72 h from the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT model indicated that areas east and north-east of the study site were the main sources of the airborne particles. Although the combined risk associated with levels of Pb, Cr, Co., Ni, Zn, As, Cd, V, and Mn was far below the standards mentioned in international guidelines, the lifetime cancer risks associated with As and Cr levels exceeded US-EPA guidelines, and may expose inhabitants of surrounding areas of Bangkok to an elevated cancer risk.

  14. Water-soluble ions and carbon content of size-segregated aerosols in New Delhi, India: direct and indirect influences of firework displays.

    Science.gov (United States)

    Kumar, Pawan; Kumar, Rakesh; Yadav, Sudesh

    2016-10-01

    The particle size distribution and water-soluble inorganic ion (WSII) and carbonaceous species in size-segregated aerosols, Dp firework displays in New Delhi, India. The firework activity had the maximum contribution to the mass loading of PM 0.95 (786 μg/m 3 ) followed by PM 0.95-1.5 (216 μg/m 3 ) with all other three fractions accounting to a total of 214 μg/m 3 . The percentage contributions of WSII to the total mass of aerosols were highest in first two size fractions (39 and 40 %, respectively), compared to other fractions. The firework marker ion (Mg 2+ , Cl - , and K + ) mass concentration shows higher values in PM 0.95 during Diwali compared to before Diwali period. The mass size distribution of particles, NH 4 + , K + , Cl - , SO 4 2- , Mg 2+ , and NO 3 - , also showed changes on the Diwali night compared to previous and after days. The high Cl - /Na + (5.6) and OC/EC (3.4) ratio of PM 0.95 can be used as the indicators of firework displays. The lowering of mixing height on Diwali night to 50 m compared to before (277 mts) and after (269 mts) Diwali period further concentrated the aerosols in ambient atmosphere. Therefore, the firework display not only released the gaseous or elemental constituent but also influenced the temperature profile and both put together result in high aerosol concentrations, WSII, OC, and BC contents in ambient atmosphere. The alveolar, respirable, and inhalable fractions accounted for 64.6, 90.8, and 97.8 %, respectively, of the total PM 10 mass. People stay exposed to such high pollution level in short span of 6-8 h and experience adverse health impacts due to high mass concentrations and the chemical components of fine aerosols.

  15. PERSPECTIVE: Fireworks and radioactivity

    Science.gov (United States)

    Breitenecker, Katharina

    , resulting in potential negative health effects, unless an extensive purification of the ores is undertaken. From the environmental and toxicological point of view, the formation of barium-rich aerosols following the display of fireworks is a problem. The barium compounds released are mainly in a bioavailable form. Considering the chemical similarities of barium and strontium to radium, the potential hazard of fireworks due to liberated radionuclides might be of interest. Ores and compounds used for pyrotechnic devices are usually purified only to the grade that is necessary for the intended effect. Thus, fireworks can contain traces of heavy metals which do not have a pyrotechnic function [5, 7, 8]. The incorporation, and thus, the inhalation of α-emitters (such as 226Ra) is a major health issue in human radiation protection. In order to examine the potential hazard Georg Steinhauser and Andreas Musilek investigated this topic. Although the specific radium activities were relatively low in the investigated samples, Steinhauser and Musilek showed that radium is significantly enriched in pyrotechnics. This fact gives no reason why people should not attend firework displays or should not set off their own fireworks on New Year's Eve. Rather, it is now the authorities' turn to take care of this topic. What if highly active radiobarite was used as a raw material for the production of pyrotechnic indoor devices? This would definitely cause unexpected health issues. Now that the problem is identified, the authorities have to ensure that the exemption limits are not exceeded. Today, public opinion is going more and more in the direction of using eco-friendly products. A lot of products have been shown to have potential negative health effects and are therefore now produced in safer and more eco-friendly forms than they used to be a few years ago. Thus, Georg Steinhauser and Andreas Musilek demonstrated that pyrotechnics do contain a certain amount of radioactive material—so why

    Full Text Available Public displays are often strongly situated signs deeply embedded in their physical, social, and cultural setting. Understanding how the display is coupled with on-going situations, its level of situatedness, provides a key element for the interpretation of the displays themselves but is also an element for the interpretation of place, its situated practices, and its social context. Most digital displays, however, do not achieve the same sense of situatedness that seems so natural in their nondigital counterparts. This paper investigates people’s perception of situatedness when considering the connection between public displays and their context. We have collected over 300 photos of displays and conducted a set of analysis tasks involving focus groups and structured interviews with 15 participants. The contribution is a consolidated list of situatedness dimensions that should provide a valuable resource for reasoning about situatedness in digital displays and informing the design and development of display systems.

    1994-10-26

    In March 1992 a private members Bill was introduced into parliament which sought to place tighter restrictions on the sale of fireworks. The primary purpose of this research was to document the nature and extent of firework related injury in New Zealand for the purpose of preparing a submission on this Bill. Firework related injuries were examined in relation to the legislative history of fireworks control in New Zealand to ascertain if existing regulations had been effective in reducing firework injuries and whether there was justification for greater control. Between 1979 and 1992 (inclusive) 237 persons were admitted to hospital for treatment of injuries related to fireworks. The overall incidence rate for this period was 0.52 per 100,000 persons per year. Eighty five percent of all events involved males. Children (fireworks (as is proposed in the Bill). The current legislation could well be supported though, by extending the ban on the types of fireworks publicly available to include skyrockets.

  16. Whole body interaction with public displays

    CERN Document Server

    Walter, Robert

    2017-01-01

    This book develops valuable new approaches to digital out-of-home media and digital signage in urban environments. It offers solutions for communicating interactive features of digital signage to passers-by. Digital out-of-home media and digital signage screens are becoming increasingly interactive thanks to touch input technology and gesture recognition. To optimize their conversion rate, interactive public displays must 1) attract attention, 2) communicate to passers-by that they are interactive, 3) explain the interaction, and 4) provide a motivation for passers-by to interact. This book highlights solutions to problems 2 and 3 above. The focus is on whole-body interaction, where the positions and orientations of users and their individual body parts are captured by specialized sensors (e.g., depth cameras). The book presents revealing findings from a field study on communicating interactivity, a laboratory on analysing visual attention, a field study on mid-air gestures, and a field study on using mid-air...

    Public-display systems are still far from being a medium for meeting people's diverse communication goals. Moving toward open displays will require publication paradigms that can overcome the challenges of meaningful engagement and enable users to fully understand and control the publication process. The metaphors of pins and posters have inspired two complementary paradigms for public displays. Researchers implemented these paradigms in the Instant Places system, which they deployed on 10 displays in diverse urban locations for six months. They collected user and system data regarding the users' practices. The findings improve the understanding of what might drive user-generated content in networks of urban displays. Such knowledge can inform the design of tools and procedures for situated publication in public displays.

    In recent years, the celebration activities of various folk-custom festivals have been getting more and more attention from the citizens in Taiwan. Festivities throughout the whole island are traditionally accompanied by loud and brightly colored firework displays. Among these activities, the firework displays during Taiwan's Lantern Festival in Kaohsiung harbor is one of the largest festivals in Taiwan each year. Therefore, it is of importance to investigate the influence of fireworks displays on the ambient air quality during the Taiwan's Lantern Festival. Field measurements of atmospheric particulate matter (PM) were conducted on February 9th-11th, 2009 during Taiwan's Lantern Festival in Kaohsiung City. Moreover, three kinds of fireworks powders obtained from the same manufacturing factory producing Kaohsiung Lantern Festival fireworks were burned in a self-designed combustion chamber to determine the physicochemical properties of the fireworks' particles and to establish the source profile of firework burning. Several metallic elements of PM during the firework display periods were notably higher than those during the non-firework periods. The concentrations of Mg, K, Pb, and Sr in PM2.5 during the firework periods were 10 times higher than those during the non-firework periods. Additionally, the Cl-/Na+ ratio was approximately 3 during the firework display periods as Cl- came from the chlorine content of the firework powder. Moreover, the OC/EC ratio increased up to 2.8. Results obtained from PCA and CMB receptor modeling showed that major sources of atmospheric particles during the firework display periods in Kaohsiung harbor were fireworks, vehicular exhausts, soil dusts and marine sprays. Particularly, on February 10th, the firework displays contributed approximately 25.2% and 16.6% of PM10 at two downwind sampling sites, respectively.

    2017-06-01

    This study characterizes the epidemiology of nonfatal pediatric firework-related injuries in the United States among children and adolescents by analyzing data from the National Electronic Injury Surveillance System from 1990 through 2014. During this 25-year period, an estimated 136 991 (95% CI = 113 574-160 408) children firework-related injuries. The annual injury rate decreased significantly by 30.4% during this period. Most of those injured were male (75.7%), mean patient age was 10.6 years, and 7.6% required hospital admission. The hands (30.0%) were the most commonly injured body region, followed by head and neck (22.2%), and eyes (21.5%). Sixty percent of injuries were burns. Injuries were most commonly associated with firecrackers (26.2%), aerial devices (16.3%), and sparklers (14.3%). Consumer fireworks pose a serious injury risk to pediatric users and bystanders, and families should be encouraged to attend public firework displays rather than use consumer fireworks.

    Every year people sustain serious injuries when they let off fireworks on New Year's Eve. Public education and protective eye wear do not solve this problem. Experience from other countries shows that the number of injuries decreases dramatically when fireworks are handled only by experienced specialists. Medical scientific associations are invited to promote a ban on ordinary citizens letting off fireworks and for fireworks to be reserved for firework specialists only.

    A new generation of public displays demands high interactive and multiscreen features to enrich people's experience in new pervasive environments. Traditionally, research on public display interaction has involved mobile devices as the main characters during the use of personal area network technologies such as Bluetooth or NFC. However, the emergent Smart TV model arises as an interesting alternative for the implementation of a new generation of public displays. This is due to its intrinsic connection capabilities with surrounding devices like smartphones or tablets. Nonetheless, the different approaches proposed by the most important vendors are still underdeveloped to support multiscreen and interaction capabilities for modern public displays, because most of them are intended for domestic environments. This research proposes multiscreen interactive middleware for public displays, which was developed from the principles of a loosely coupled interaction model, simplicity, stability, concurrency, low latency, and the usage of open standards and technologies. Moreover, a validation prototype is proposed in one of the most interesting public display scenarios: the advertising.

    Fireworks have been identified as one ozone source by photolyzing NO 2 or O 2 and are believed to potentially be important for the nighttime ozone during firework events. In this study, we conducted both lab and field experiments to test two types of fireworks with low and high energy with the goal to distinguish whether the visible ozone signal during firework displays is real. The results suggest that previous understanding of the ozone formation mechanism during fireworks is misunderstood. Ultraviolet ray (UV)-based ozone monitors are interfered by aerosols and some specific VOCs. High-energy fireworks emit high concentrations of particular matters and low VOCs that the artificial ozone can be easily removed by an aerosol filter. Low-energy fireworks emit large amounts of VOCs mostly from the combustion of the cardboard from fireworks that largely interferes with the ozone monitor. Benzene and phenol might be major contributors to the artificial ozone signal. We further checked the nighttime ozone concentration in Jinan and Beijing, China, during Chinese New Year, a period with intense fireworks. A signal of 3-8ppbv ozone was detected and positively correlated to NO and SO 2 , suggesting a considerable influence of these chemicals in interfering with ambient ozone monitoring.

During this period, many patients from all age groups present to hospital with injuries due to fireworks. Prevalence, period of occurrence, sex and age variation, adult supervision, causative fireworks, mode of lighting, age groups prone to injury, patterns of injury caused by individual fireworks, and the body parts injured were studied. One hundred and fifty-seven cases (92 retrospective, 65 prospective) with injury due to fireworks presenting to the Department of Plastic Surgery at KEM Hospital between 1997 and 2006 were studied. The prevalence of injuries has decreased steadily over the last 10 years (41 cases in 1997, 3 cases in 2006). The maximum number of injuries (35%) was seen in the age group 5-14 years; 92% of these children were unsupervised. The commonest cause of injury was firework misuse (41% of cases), followed by device failure (35%). Device failure was commonest with flares/fountains (ground firework emitting sparks upwards) and aerial devices. Flare/fountains caused most injury (39%), sparklers the least (0.6%). Flare/fountains, ground spinners, sparklers, and gunpowder (explosive material from cracker, obtained by tearing paper wrapper and obtaining chemicals) caused only soft tissue burns; stringbombs (high-intensity fire cracker made by wrapping chemicals with jute strings/coir in layers) and rockets (aerial device that zooms upwards and bursts) caused blast injuries, leading to soft tissue disruption and bony injuries. Emergency surgery was done if indicated: tendon and/or neurovascular repair, fracture fixation, flap cover or amputation. Superficial burns were treated with dressings. Certain wounds needed only thorough cleansing of the wound and primary suturing. We concluded that, over a 10-year period, the prevalence of firework injury decreased due to increased

While personal use of fireworks was an independent risk factor for firework-related injuries, higher socio-economic status of the household and higher educational level of the head of the household were not protective factors.

    The sale to the general public of fireworks is illegal in Ireland. However, many fireworks are readily available on the black market from illegal traders. The number of firework injuries presenting to our unit during the three week run-up to Hallowe'en October 2001 was recorded. In addition, each patient was contacted to determine how the fireworks were obtained, the average amount of money spent, and the level of adult supervision present at the time of injury. A total of 19 patients presented, 18 from the local catchment area, with a mean age of 16 yrs (range 5-46 yrs). Thirteen patients required admission. Sixteen patients sustained hand injuries including burns, and three sustained burns to other body areas. The amount of money spent varied between adults and children, the average amount among the paediatric group was Euro 2-4, but Euro 45 in the adult group. None were willing to identify the local source of their fireworks, but most fireworks originated in Northern Ireland. This small review highlights an ongoing problem in Ireland; fireworks are illegal, yet they are easily and cheaply available without quality or safety controls. Our public awareness campaign has failed to reach its target audience, and the illegal traders who sell these often inferior products are seldom charged. Children and adults will continue to sustain serious injuries as a result.

    Class C fireworks are those which can be readily purchased by the public. Between July 1971 and August 1988, 23 patients were admitted to our institution with firework injuries. Fourteen patients (60.9%) sustained injuries related to Class C fireworks. All patients were males with a mean age of 9.0 +/- 3.6 years, with a total body surface area (TBSA) burn of 18 +/- 20% with 10 +/- 15% being full thickness. Thirteen of the 14 patients required hospitalization. Five patients were admitted acutely and eight patients were referred to our institution at least 3 days postinjury. All patients required operative intervention in order to obtain wound closure. Patients admitted acutely showed a decrease in length of hospital stay and patient morbidity when compared to referral patients. Our data suggest that class C firework injuries, although small in terms of TBSA burned, result in full-thickness wounds that warrant aggressive surgical management.

    The purpose of this study was to observe the occurrence and character of firework injuries on the two days around New Year in Denmark over the last decade. Since 1995/1996 all Accident and Emergency Departments in Denmark have registered all contacts where fireworks were the cause of injury on 31st December and 1st January. Data comprised hospital, sex, age, type of firework, diagnosis and final treatment. Follow-up and reminder by phone secured a 100% response rate. The total number of injured patients was 4,447. The number of firework injuries on the 31st of December and 1st of January was reduced by half over the 12-year period. Furthermore, the number of firework injuries caused by illegal fireworks in 2006/2007 was only 10% of the number in 1996/1997. Only 8% of injuries on last New Year's Eve were caused by illegal firewoks compared to almost 50% at the beginning of the period. A similar halving is seen in serious injuries. Roughly one quarter sustained injuries to the eyes, one quarter to the head/neck and 38% to hands. Firework injuries are now half of the level in 1996/1997. Injuries caused by illegal fireworks and serious injuries have shown a downward tendency throughout the period. The actual number of severe injuries from illegal fireworks is now only 10% of the level in the mid-1990s. This reduction can be attributed to preventive campaigns, greater knowledge of the risk of fireworks in general as well as legislation. Continued focus on preventive campaigns, control of fireworks for the general public and control of firework distribution to professionals is recommended.

    Full Text Available Analysis of the annual fireworks-related injury surveillance data collected by the Philippines Department of Health (DOH in 2010–2014 was conducted to describe the profile of such injuries in the Philippines. Surveillance data were collected from DOH’s Online National Electronic Injury Surveillance System and analysed. A case was defined as any person who had sustained injury from fireworks in any form within the 16-day surveillance period (21 December to 5 January and had presented to any of the 50 sentinel hospitals. Of the 4649 cases, there were 4706 fireworks-related injuries involving 5076 anatomic sites in 2010–2014. A significant decrease of cases in 2014 was observed when compared with the previous study years (P = 0.02. The number of cases peaked at public holidays. Males (80% were more commonly injured, and children aged 5 to 14 years were primarily affected (47%. Ignition of illegal fireworks accounted for half (50% of the injuries; most injuries (68% occurred in street settings. The majority of injuries (57% were sustained by fireworks igniters. The most common anatomic injury sites were hands (44%, legs (21% and eyes (14%. Illegal fireworks were related to 100% (4/4 of the deaths and 49% (105/214 of the cases who needed amputations. Fireworks-related injuries declined significantly in 2014. Public awareness campaigns may have contributed to reducing the injury occurrences. As illegal fireworks accounted for all deaths and more than half of the amputations, law enforcement should be directed toward preventing importing, distributing and using illegal fireworks.

    2014-06-01

    Full Text Available Science on a Sphere (SoS is a compelling educational display installed at numerous museums and planetariums around the world; essentially the SoS display is a large spherical surface on which multicolor high-resolution depictions of (e.g. planetary weather maps may be depicted. Fascinating as the SoS display is, however, it is in practice restricted to the use of museum professionals; students (and for that matter, older museum visitors are unable to create their own displays for the surface. This paper describes a working software system, Math on a Sphere (MoS, that democratizes the SoS display by providing a simple programming interface to the public, over the World Wide Web. Briefly, our system allows anyone to write programs for spherical graphics patterns, and then to upload those programs at a planetarium or museum site and see the result on the giant sphere. This paper describes the implementation of the MoS system; sketches a sample project; and concludes with a more wide-ranging discussion of our user testing to date, as well as strategies for empowering children and students with greater control of public displays.

  10. A Cooperative Framework for Fireworks Algorithm.

    Science.gov (United States)

    Zheng, Shaoqiu; Li, Junzhi; Janecek, Andreas; Tan, Ying

    2017-01-01

    This paper presents a cooperative framework for fireworks algorithm (CoFFWA). A detailed analysis of existing fireworks algorithm (FWA) and its recently developed variants has revealed that ( i) the current selection strategy has the drawback that the contribution of the firework with the best fitness (denoted as core firework) overwhelms the contributions of all other fireworks (non-core fireworks) in the explosion operator, ( ii) the Gaussian mutation operator is not as effective as it is designed to be. To overcome these limitations, the CoFFWA is proposed, which significantly improves the exploitation capability by using an independent selection method and also increases the exploration capability by incorporating a crowdness-avoiding cooperative strategy among the fireworks. Experimental results on the CEC2013 benchmark functions indicate that CoFFWA outperforms the state-of-the-art FWA variants, artificial bee colony, differential evolution, and the standard particle swarm optimization SPSO2007/SPSO2011 in terms of convergence performance.

    1991-12-01

    A total of 38 cases of fireworks related injuries from Hospital USM over a 5-year period from 1986 to 1990 during Hari Raya festival were analysed. The majority (68.5%) of the patients were teenagers, between 10 to 19 years of age. All the cases were Malays and most of the accidents occurred before the Hari Raya Idilfitri festive seasons. Fourteen cases were caused by self-made fireworks and another 16 cases were due to modified fire-works. Twenty-four cases suffered permanent disabilities mostly finger amputations. Such injuries could be prevented by law enforcement coupled with public health education to modify social behaviour especially when the ban against the use of fireworks is lifted on religious grounds.

  14. On firework blasts and qualitative parameter dependency.

    Science.gov (United States)

    Zohdi, T I

    2016-01-01

    In this paper, a mathematical model is developed to qualitatively simulate the progressive time-evolution of a blast from a simple firework. Estimates are made for the blast radius that one can expect for a given amount of detonation energy and pyrotechnic display material. The model balances the released energy from the initial blast pulse with the subsequent kinetic energy and then computes the trajectory of the material under the influence of the drag from the surrounding air, gravity and possible buoyancy. Under certain simplifying assumptions, the model can be solved for analytically. The solution serves as a guide to identifying key parameters that control the evolving blast envelope. Three-dimensional examples are given.

  15. An assessment of firework particle persistence on the hands and related police force practices in relation to GSR evidence.

    Science.gov (United States)

    Grima, Matthew; Hanson, Robert; Tidy, Helen

    2014-06-01

    In a previous study by Grima et al. Sci. Justice 52 (1) (2012) 49, it was shown that background particles can aid in the exclusion of firework particles which are indistinguishable from GSR. Issues relating to the persistence of such particle populations were presented. The scope of this project was to examine persistence on the hands in the context of possible post-display scene contamination and how this can affect GSR evidence, especially in light of possible GSR/firework mixtures. Persistence was investigated by recovering firework residues eight hours post-display following contact of the hands with bedding. In addition, particle profiling was carried out using SEM-EDX. Firework particle populations exhibited strong persistence in all displays, with not less than 667 particles persisting in each scenario. This factor challenges GSR evidence, especially if personnel stationed at display sites enter scenes of crime or come into contact with suspects after a display. A survey of UK police force practices following firework displays showed that authorities are not aware of the impact particle transfer may have on GSR evidence. Recommendations for the implementation of basic hygiene practices for particle transfer control have also been made. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  16. Effect of fireworks on ambient air quality in Malta

    Science.gov (United States)

    Camilleri, Renato; Vella, Alfred J.

    2010-11-01

    Religious festivals ( festas) in the densely populated Maltese archipelago (Central Mediterranean) are ubiquitous during summer when 86 of them are celebrated between June and October, each involving the burning of fireworks both in ground and aerial displays over a period of 3 days or longer per festival. We assessed the effect of fireworks on the air quality by comparing PM 10 and its content of Al, Ba, Cu, Sr and Sb which materials are used in pyrotechnic compositions. PM 10 was collected mainly from two sites, one in Malta (an urban background site) and the other in Gozo (a rural site) during July-August 2005 when 59 feasts were celebrated and September-October 2005 when only 11 feasts occurred. For both Malta and Gozo, PM 10 and metal concentration levels measured as weekly means were significantly higher during July-August compared to September-October and there exist strong correlations between PM 10 and total metal content. Additionally, for Malta dust, Al, Ba, Cu and Sr correlated strongly with each other and also with total concentration of all five metals. The same parameters measured in April 2006 in Malta were at levels similar to those found in the previous October. Ba and Sb in dust from the urban background site in Malta during July-August were at comparable or higher concentration than recently reported values in PM 10 from a heavily-trafficked London road and this suggests that these metals are locally not dominated by sources from roadside materials such as break liner wear but more likely by particulate waste from fireworks. Our findings point to the fact that festa firework displays contribute significantly and for a prolonged period every year to airborne dust in Malta where PM 10 is an intractable air quality concern. The presence in this dust of elevated levels of Ba and especially Sb, a possible carcinogen, is of concern to health.

    Fireworks are used to celebrate a variety of religious, patriotic, and cultural holidays and events around the world. Fireworks are common in the United States, with the most popular holiday for their use being national Independence Day, also known as July Fourth. The use of fireworks within the context of celebrations and holidays presents the ideal environment for accidents that lead to severe and dangerous injuries. Injuries to the face from explosions present a challenging problem in terms of restoring ideal ocular, oral, and facial function. Despite the well documented prevalence of firework use and injury, there is a relatively large deficit in the literature in terms of firework injury that involves the face. We present a unique case series that includes 4 adult male patients all with severe firework injuries to the face that presented at an urban level 1 trauma center. These four patients had an average age of 26.7 years old and presented within 5 hours of each other starting on July Fourth. Two patients died from their injuries and two patients underwent reconstructive surgical management, one of which had two follow up surgeries. We explore in detail their presentation, management, and subsequent outcomes as an attempt to add to the very limited data in the field of facial firework blast injury. In addition, the coincidence of their presentation within the same 5 hours brings into question the availability of the fireworks involved, and the possibility of similar injuries related to this type of firework in the future.

Despite the well documented prevalence of firework use and injury, there is a relatively large deficit in the literature in terms of firework injury that involves the face. We present a unique case series that includes 4 adult male patients all with severe firework injuries to the face that presented at an urban level 1 trauma center. These four patients had an average age of 26.7 years old and presented within 5 hours of each other starting on July Fourth. Two patients died from their injuries and two patients underwent reconstructive surgical management, one of which had two follow up surgeries. We explore in detail their presentation, management, and subsequent outcomes as an attempt to add to the very limited data in the field of facial firework blast injury. In addition, the coincidence of their presentation within the same 5 hours brings into question the availability of the fireworks involved, and the possibility of similar injuries related to this type of firework in the future.

    Measurements for particles 10 nm to 10 μm were taken using a Wide-range Particle Spectrometer during the Chinese New Year (CNY) celebrations in 2009 in Shanghai, China. These celebrations provided an opportunity to study the number concentration and size distribution of particles in an especial atmospheric pollution situation due to firework displays. The firework activities had a clear contribution to the number concentration of small accumulation mode particles (100-500 nm) and PM 1 mass concentration, with a maximum total number concentration of 3.8 × 10 4 cm -3. A clear shift of particles from nucleation and Aitken mode to small accumulation mode was observed at the peak of the CNY firework event, which can be explained by reduced atmospheric lifetimes of smaller particles via the concept of the coagulation sink. High particle density (2.7 g cm -3) was identified as being particularly characteristic of the firework aerosols. Recalculated fine particles PM 1 exhibited on average above 150 μg m -3 for more than 12 hours, which was a health risk to susceptible individuals. Integral physical parameters of firework aerosols were calculated for understanding their physical properties and further model simulation.

    Badge systems, a common mechanism for gamification on social media platforms, provide a way for users to present their knowledge or experience to others. This study aims to contribute to the understanding of why social media users publicize their achievements in the form of online badges. Five motivational factors for badge display in public networked environments are distinguished-self-efficacy, social incentives, networked support, passing time, and inattentive sharing-and it is suggested that different badge types are associated with different motivations. System developers are advised to consider these components in their designs, applying the elements most appropriate to the communities they serve. Comparing user motivations associated with badges shared across boundaries provides a better understanding of how online badges relate to the larger social media ecosystem.

    Full Text Available A fireworks algorithm (FWA is a recent swarm intelligence algorithm that is inspired by observing fireworks explosions. An adaptive fireworks algorithm (AFWA proposes additional adaptive amplitudes to improve the performance of the enhanced fireworks algorithm (EFWA. The purpose of this paper is to add opposition-based learning (OBL to AFWA with the goal of further boosting performance and achieving global optimization. Twelve benchmark functions are tested in use of an opposition-based adaptive fireworks algorithm (OAFWA. The final results conclude that OAFWA significantly outperformed EFWA and AFWA in terms of solution accuracy. Additionally, OAFWA was compared with a bat algorithm (BA, differential evolution (DE, self-adapting control parameters in differential evolution (jDE, a firefly algorithm (FA, and a standard particle swarm optimization 2011 (SPSO2011 algorithm. The research results indicate that OAFWA ranks the highest of the six algorithms for both solution accuracy and runtime cost.

    Full Text Available JuxtaLearn is a research project focused on ‘performance’ as a means of provoking students’ understanding of science and technology through the creation and sharing of educational videos. As the videos will be shared in public displays, the Portuguese research team developed three workshops with twelve teachers from a Portuguese Secondary School representing different school departments and sharing organizational responsibilities. The aim was to generate scenarios of possible features and interaction for the curricular integration of the technological device. Our findings suggest that teachers are not motivated to use, on their own, technologies in the classroom, but receptive to new and challenging technologies when properly stimulated. They were able to generate scenarios that take advantage of the possibilities offered by digital public displays to stimulate learning processes. However, there are pedagogical, organizational and ethical concerns in the management and control of content that need to be resolved before they feel confortable to deal with change and technological innovation.

    To identify the patterns of ocular injury and to determine ocular morbidity resulting from the use of firecrackers. A prospective observational study of all patients presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in South India over a one-month period around the autumn festival of Diwali. We also reviewed the published literature from around the world reporting ocular injuries due to firecrackers. 49 patients were included in the study, out of which the vast majority (40/81%) were males. The mean age was 17 years. Almost an equal number of bystanders (24/48.9%) was affected as compared to people handling the fireworks (25/51%). 13 (26.53%) patients had open-globe injury whereas 33 (67.34%) patients had closed-globe injury. Twenty-two (44.8%) patients underwent surgical intervention. Eighteen (36.7%) patients had final vision less then 20/40 (range = 20/50 to No Perception of Light) with eight patients having no perception of light in the affected eye. Unregulated use of firecrackers can lead to significant ocular morbidity, mainly involving children, young males, and even innocent bystanders. A combination of public awareness and appropriate legislative laws should be formulated regarding the use of fireworks to decrease the load of needless blindness on society.

    Energy labels have generally received positive response from consumers and have moved the market for white goods and cars in the direction of more energy-efficient products. On the real estate market, it was expected that an energy label, rating the energy performance of a property based on a national energy performance certificate (EPC) might receive similar response. However, in Denmark no response to the energy performance rating was observed for 15 years. This was a surprise considering that Denmark was the first country to implement an A to G rating of the energy performance of buildings. A statistical examination of data on property sales prices and energy performance ratings was carried out. All relevant property transaction data from 2007 till 2012 were examined and they showed that energy performance ratings had an impact on property sales prices. However, before June 2010, the impact was modest, whereas after June 2010 the impact of energy performance ratings on property sales prices increased significantly as a result of an EU requirement to display the energy performance rating in connection with property sales. On this background, it was concluded that a public display of the energy performance rating is fundamental for market response. - Highlights: •Energy performance ratings of buildings have an impact on property sales prices. •A statistical examination shows that since 2010 sales prices reflect energy performance. •Mandatory display of the rating prescribed by EU Directive was decisive. •The positive market response will be an incentive for energy upgrading of the property.

    To document the clinical features, management and visual outcome of fireworks-related ocular injuries during the Spring Festival. A retrospective analysis of all patients with fireworks-related ocular injuries attending the Department of Ophthalmology in Renmin Hospital of Wuhan University from January 20 to February 10, 2009. Age, gender, laterality, type of fireworks, location of incident, initial best-corrected visual acuity (BCVA), diagnosis, management, and final BCVA at last follow-up were documented. Relevant clinical features and visual outcome were evaluated. We observed 25 eyes in 24 patients. Injuries were more frequent in children (ten, 41.7%), males (19, 79.2%), and as open globe injury (15, 62.5%). The most common pyrotechnical products causing accidents were firecrackers (12, 50%). Rural residents had significantly higher rates of injury compared to urban residents (P = 0.023). Of 25 eyes, the most common injuries were corneal/scleral/corneoscleral open globe trauma (15, 60%), traumatic cataract (14, 56%), vitreous hemorrhage (seven, 28%) and retinal detachment (seven, 28%). Most eyes (23, 92%) received surgical intervention, including one (4%) eye enucleation. Vitrectomy was the most surgical treatment. After management, visual outcomes showed statistically significant improvement (P = 0.008). Initial BCVA correlated strongly with final BCVA (P = 0.010). Fireworks-related ocular injuries occur mainly in children, males and rural settings, are frequently severe and visually devastating. Therefore, preventive measures should be strengthened, including public education and legal restriction on the sale and use of fireworks.

    Japan Nuclear Cycle Development Institutes (JNC) has a few thousands of short term visitors to Geological Isolation Basic Research Facility of Tokai works in every year. From the viewpoint of promotion of the visitor's understanding and also smooth communication between researchers and visitors, the explanation of the technical information on geological disposal should be carried out in more easily understandable methods, as well as conventional tour to the engineering-scale test facility (ENTRY). This paper reports on the background information and the appearance of displays, which were installed at ENTRY, to promote public understanding of geological repository concept and the spatial scale. They have been practically used as one of the explanation tools to support visitor's understanding. (author)

    2014-01-01

    The main objective of this study is to examine the association between work with data display screens (DDS) and ocular hypertension (OHT). A cross-sectional study among local public sector workers (Diputación Provincial de Valencia). Data from 620 people were collected over 25 months, from periodic medical examinations performed at an occupational health unit. Intraocular pressure (IOP) was obtained with a portable puff tonometer validated for screening, establishing the cut-off point for OHT at 22 mmHg. Both biological characteristics and other work-related variables were taken into account as covariates. Descriptive statistics of the data were obtained, together with nonparametric tests with a level of significance of 95% and logistic regression with p 〈0.1 as the level of significance of the likelihood test. The average age of the study population is 52.8 years. The prevalence of OHT was 3.5% (5.1% among men and 1.2% among women; p=0.012). No significant associations were found between hours of DDS-related work and OHT were found (p=0.395). Logistic regression corroborated the association between gender and OHT, with women less affected (OR = 0.234; 95%CI: 0.068 - 0.799; p=0.020). In our study, no associations were found between time of exposure to data display screens and ocular hypertension. Logistic regression points to a certain association between ocular hypertension and gender, with men being more predisposed. Copyright belongs to the Societat Catalana de Salut Laboral.

    On July 1st on 'Territory Day', the public in the Northern Territory are permitted to purchase and operate consumer fireworks without a licence. Serious permanent injuries from fireworks are well described, leading to their banning in many other jurisdictions. This study describes those seriously injured by fireworks in the Top End of the Northern Territory, with the aim of identifying opportunities for prevention and harm minimization. This is a retrospective audit of all admitted patients with an injury from fireworks at the Royal Darwin Hospital between 2000 and 2015. The variables collected included demographic data and the circumstances around injury (operator versus bystander, alcohol involvement and day of device operation). The consequences such as injuries, operating theatre visits, length of stay and outpatient visits are described. Fifty-five patients (including 17 children) suffered 67 injuries over the study period, resulting in 68 operating theatre visits, 322 hospital days and 380 outpatient appointments. Burns, hand and eye injuries predominate. Females (P = 0.000) and children (P = 0.029) were more likely to be injured as bystanders. Injuries on a day other than Territory Day were more likely to have alcohol involvement (P = 0.01), and occur in the operator (P = 0.017). Consumer firework usage results in a small number of life altering injuries annually. Previous prevention campaigns focusing on device user safety should be expanded to include the safety of bystanders and children and reduce firework usage outside of the Territory Day. © 2017 Royal Australasian College of Surgeons.

    2014-01-01

    The world-wide use of fireworks with their consequent detrimental effect on the air quality is widely recognized with elevated ambient air levels of particulate matter and its several metallic components and gases identified in several studies carried out during such events. Exposed individuals may be at risk following inhalation of such produced pollutants. This review focuses on the impact of fireworks on air quality and the potential effect of fireworks on the respiratory system of healthy individuals as well as those suffering from underlying respiratory diseases, particularly asthma and chronic obstructive pulmonary disease (COPD). This applies not only to spectators including children but also to pyrotechnicians themselves. An extensive Medline search revealed that a strong evidence of the impact of fireworks on respiratory health is lacking in susceptible as well as healthy individuals with no formal studies on COPD or asthma, other than a few case reports in the latter. The implementation of global strategies to control the use of fireworks and hence improve air quality could possibly reduce their likely detrimental effect on human respiratory health in exposed individuals, but clearly a more targeted research is needed.

    To prospectively study mechanisms and injury characteristics of ocular firework burns. A prospective analysis of all patients with firework injuries attending the Department of Ophthalmology, University of Vienna, between 1994 and 2001. We looked for classes of fireworks and mechanisms of injuries. The number of diagnoses was established and their severity classified. During this period (8 years) we identified 116 eyes of 102 patients. 67/102 (66%) of all injuries were caused by class II and III fireworks. Patients ranged between 4 and 83 years. Ocular injuries occurred more frequently in males (69, 68%) and affected the right eye in 53 patients (52.5%). Ocular firework injuries to minors (under the age of 18 years) occurred in 48 (49%). The most common types of injury were skin and corneal erosions and abrasions (32/116, 28%). 11/116 eyes (10%) had severe injuries. 8 of 11 severe injuries (72%) occurred in minors (<18 years). 2 patients (1.7%) developed permanent blindness. In 32/116 patients (28%), the ocular trauma resulted in visual impairment, mainly due to corneal scars or retinal pathologies. In all patients, the severity index was 1.4 +/- 0.8. In minors the severity index was 1.6 +/- 1.0, in adults 1.2 +/- 0.5 (p = 0.013). Injuries in minors were significantly more severe than those in adults. Possible preventive measures include legislation, education of minors and eye protection. Copyright 2002 S. Karger AG, Basel

    Intensive firecracker/firework displays during Chinese New Year (CNY) release fine particles and gaseous pollutants into the atmosphere, which may lead to serious air pollution. We monitored ambient PM{sub 2.5} and black carbon (BC) concentrations at a regional background site in the Yellow River Delta region during the CNY in 2011. Our monitoring data and MOUDI images showed that there was a haze event during the CNY. Daily average PM{sub 2.5} concentration reached 183 μg m{sup −3} during the CNY, which was six times higher than that before and after the CNY. Similarly, the black carbon (BC) concentrations were elevated during the CNY. In order to confirm whether the firecracker/firework related emission is the main source of the haze particles, we further analyzed the morphology and chemical composition of individual airborne particles collected before, during and after the CNY by using transmission electron microscopy coupled with energy-dispersive X-ray spectroscopy (TEM/EDS). We found that sulfate and organic-rich particles were dominant in the atmosphere before and after the CNY. In contrast, K-rich sulfates and other metal (e.g., Ba-rich, Al-rich, Mg-rich, and Fe-rich) particles were much more abundant than ammoniated sulfate particles during the CNY. These data suggest that it was the aerosol particles from the firecracker/firework emissions that induced the regional haze episode during the CNY. In individual organic and K-rich particles, we often found more than two types of nano-metal particles. These metal-bearing particles also contained abundant S but not Cl. In contrast, fresh metal-bearing particles from firecrackers generated in the laboratory contained abundant Cl with minor amounts of S. This indicates that the firecracker/firework emissions during the CNY significantly changed the atmospheric transformation pathway of SO{sub 2} to sulfate. - Highlights: ► TEM was used to observe the aged individual particles from firecrackers/fireworks

    While there is some evidence in the literature on the impact of art therapy for consumers, there is comparatively little written on how art that has been created by consumers impacts on those observing the art. This paper reports on a qualitative research study that sought to determine if publically-displayed art created by young consumers impacted on stigma reduction and self-help-seeking behaviours of the observers. The findings derived from the thematic analysis of qualitative interviews suggested that publically-displayed art is a safe medium, through which empathy and understanding towards young people with mental illness can be enhanced, and that the art generates discussion and self-help behaviours for mental illness. These findings highlight how mental health nurses can promote social inclusion and reduce stigma through public mental health initiatives that are an important inclusion in the scope of mental health nursing practice. © 2014 Australian College of Mental Health Nurses Inc.

A single-center, retrospective, hospital-based case series presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in North India during the 5 days of Diwali festival from 2011 to 2015 was conducted. A total of 53 eyes of 45 patients were included in the study, out of which the vast majority (39/87%) were males. The mean age was 20.55 years. Almost an equal number of bystanders (25/55.5%) were affected as compared to people handling the fireworks (20/44.44%). Five (9.43%) eyes had open-globe injury, whereas 48 (90.56%) eyes had closed-globe injury. Eighteen (33.96%) eyes underwent surgical intervention. Thirty-three (62.26%) eyes had final vision >20/200 with eight (15.09%) eyes being vision Firework-related ocular trauma can lead to serious visual impairment. Mandatory legislative laws pertaining to the manufacture, sale, and use of fireworks and creating public awareness can reduce the incidence of this preventable cause of blindness in the society. Initiating new policies for retailers involved in sale of these firecrackers can also bring in decrease of such morbidities.

    The Q-switched ruby laser (QSRL) has a good track record for traumatic tattoo removal. An unusual case of QSRL-treatment of a traumatic tattoo composed of firework debris is presented. A young man's traumatic tattoo, composed of firework debris, underwent QSRL ablation at 4-7 J/cm2 (pulse width 5 mm; duration 20 ns). Each test pulse produced visible sparks and focal projectile ejection of skin with pox-like scar formation. Caution is advised when using the QSRL for the treatment of traumatic tattoos composed of potentially combustible debris.

    Changes in U.S. fireworks laws have allowed younger children to purchase fireworks. In addition, the changes have allowed individuals to purchase more powerful fireworks. The purpose of this study is to examine the epidemiology of pediatric firework-related burn injuries among a nationally representative sample of the United States for the years 2006 to 2012. We examined inpatient admissions for pediatric firework-related burn patients from 2006 to 2012 using the nationwide inpatient sample and examined emergency department admissions using the nationwide emergency department sample. Both data sources are part of the Healthcare Cost and Utilization Project. Trajectories over time were evaluated. A total of 3193 injuries represented an estimated 90,257 firework-related injuries treated in the United States from 2006 to 2012. A majority of injuries were managed in the emergency department (n = 2008, 62.9%). The incidence generally increased over time; increasing from 4.28 per 100,000 population in 2006 to 5.12 per 100,000 population in 2012, P = .019. However, the proportion of injuries requiring inpatient admission (28.9% in 2006 to 50.0% in 2012, P fireworks laws may have had a modest effect on incidence of related injuries and the age of purchaser. However, it has had a dramatic effect on the severity of the related injuries, resulting in more inpatient admissions and longer length of stay in the hospital. Preventative methods should be taken to reduce the rate and severity of firework-related injuries among U.S. youths.

    Simple Summary The negative effects of fireworks on companion animals have been reported, but little has been documented on the impact on horses. Horse anxiety was commonly associated with fireworks, and 26% of owners reported horse injuries as a result of fireworks. Many management strategies were seen as ineffective. The majority of horse owners were in favour of a ban on the sale of fireworks for private use. Abstract Within popular press there has been much coverage of the negative effects associated with firework and horses. The effect of fireworks has been documented in companion animals, yet no studies have investigated the negative effects, or otherwise, of fireworks on horses. This study aims to document horse responses and current management strategies to fireworks via an online survey. Of the total number of horses, 39% (1987/4765) were rated as “anxious”, 40% (1816/4765) “very anxious” and only 21% (965/4765) rated as “not anxious” around fireworks. Running (82%, 912/1107) was the most common behaviour reported, with no difference between property type (p > 0.05) or location (p > 0.05). Possibly as a consequence of the high frequency of running, 35% (384/1107) of respondents reported having horses break through fences in response to fireworks and a quarter (26%, 289/1099) reported that their horse(s) had received injuries associated with fireworks. The most common management strategy was moving their horse(s) to a paddock away from the fireworks (77%) and to stable/yard them (55%). However, approximately 30% reported these management strategies to be ineffective. Of the survey participants, 90% (996/1104) were against the sale of fireworks for private use. PMID:27005667

  11. The Characteristics of Air Pollutants during Two Distinct Episodes of Fireworks Burning in a Valley City of North China.

    Yang Song

    Full Text Available The elevation and dissipation of pollutants after the ignition of fireworks in different functional areas of a valley city were investigated.The Air Quality Index (AQI as well as inter-day and intra-day concentrations of various air pollutants (PM10, PM2.5, SO2, NO2, CO, O3 were measured during two episodes that took place during Chinese New Year festivities.For the special terrain of Jinan, the mean concentrations of pollutants increased sharply within 2-4 h of the firework displays, and concentrations were 4-6 times higher than the usual levels. It took 2-3 d for the pollutants to dissipate to background levels. Compared to Preliminary Eve (more fireworks are ignited on New Year's Eve, but the amounts of other human activities are also lesser, the primary pollutants PM2.5, PM10, and CO reached higher concentrations on New Year's Eve, and the highest concentrations of these pollutants were detected in living quarters. All areas suffered from serious pollution problems on New Year's Eve (rural = urban for PM10, but rural > urban for PM2.5. However, SO2 and NO2 levels were 20%-60% lower in living quarters and industrial areas compared to the levels in these same areas on Preliminary Eve. In contrast to the other pollutants, O3 concentrations fell instead of rising with the firework displays.Interactions between firework displays and other human activities caused different change trends of pollutants. PM2.5 and PM10 were the main pollutants, and the rural living quarter had some of the highest pollution levels.

    In order to characterize the aerosol optical properties during different pollution episodes that occurred in Beijing, the aerosol loading, scattering, and size distributions are presented using solar and sky radiance measurements from 2001 to 2010 in this paper. A much higher aerosol loading than the background level was observed during the pollution episodes. The average aerosol optical depth (AOD) is largest during dust episodes coupled with the lowest Ångström exponent (α), while higher AOD and lower α were more correlated with firework and biomass burning days. The total mean AOD at 440, 675, 870 and 1020 nm were 0.24, 0.49, 0.64 and 1.38 in the clean, firework display, biomass burning and dust days, respectively. The mean α for dust days was 0.51 and exceeded 1.1 for the remaining episodes. The size distribution of the dusty periods was dominated by the coarse mode, but the coarse mode was similar magnitude to the fine mode during the firework and biomass burning days. The volume concentration of the coarse mode during the dust days increased by a magnitude of more than 2-8 times that derived in the other three aerosol conditions, suggesting that dust is the major contributor of coarse mode particles in Beijing. The single scattering albedo (SSA) values also increased during the pollution episodes. The overall mean SSA at the four wavelengths were 0.865, 0.911, 0.922 and 0.931 in clean, firework display, biomass burning, and dust days in Beijing, respectively. However, in the blue spectral range, the dust aerosols exhibited pronounced absorption.

  13. Factors influencing effectiveness of exhibit displays on family learning in a public aquarium

    Jeffery, Kodi Rae

    An important goal in science education reform is to create a scientifically literate society. The American Association for the Advancement of Science (1989b) has stated that for people to understand biology, they must first have personal experiences with it. There are severe limitations on the types of firsthand biology experiences available in the classroom. Informal learning institutions, however, are not limited by these constraints. Visitors enjoy a free-choice environment, where they can thoroughly explore things unavailable in most classrooms. Thus, museums are key resources that may help society achieve scientific literacy. This study asked what aspects of the Aquarium of the America's labeling system promote visitor learning. I looked at characteristics of both the text and the displays themselves. By using open-ended interviews rather than formal questionnaires, I allowed visitors to identify information pertinent to them. After observing families viewing the Aquarium's "Living in Water" exhibit, I interviewed them to learn what had made an impact on them. One to two months later, I conducted follow-up interviews with each family member. Although families did not come away with the strong cognitive gains we might desire, they did come away with some strong episodic memories. Visitors tended to describe their interactions with each other and the displays rather than the actual label content---except for cartoon labels. Nevertheless, when visitors found displays that raised questions, they were curious to find answers and more likely to mention them. Families also described more details of interactive displays, particularly those that used various senses and emotions. Such potentially powerful interactives must be carefully tested, or we may create tenacious misconceptions rather than greater understanding. Based on my observations, I developed an Exhibit Interactivity Rubric (EIR) which may be useful in developing meaningful exhibits. Some families created

    Full Text Available The Fireworks Algorithm is a recently developed swarm intelligence algorithm to simulate the explosion process of fireworks. Based on the analysis of each operator of Fireworks Algorithm (FWA, this paper improves the FWA and proves that the improved algorithm converges to the global optimal solution with probability 1. The proposed algorithm improves the goal of further boosting performance and achieving global optimization where mainly include the following strategies. Firstly using the opposition-based learning initialization population. Secondly a new explosion amplitude mechanism for the optimal firework is proposed. In addition, the adaptive t-distribution mutation for non-optimal individuals and elite opposition-based learning for the optimal individual are used. Finally, a new selection strategy, namely Disruptive Selection, is proposed to reduce the running time of the algorithm compared with FWA. In our simulation, we apply the CEC2013 standard functions and compare the proposed algorithm (IFWA with SPSO2011, FWA, EFWA and dynFWA. The results show that the proposed algorithm has better overall performance on the test functions.

    For an effective emergency response and implementation of counter measures, communication during a nuclear emergency is a very important aspect. The declaration of a nuclear emergency must be immediately conveyed to all those working in the plant and around the nuclear site. Besides this, the nature of emergency also needs to be conveyed unambiguously along with corresponding counter measures, such as stay in, evacuation or all clear signal for the relevant plants. This requirement has necessitated the need for a networked signaling system. Based on this requirement, a microcontroller based signaling and a telephone/wireless based communication and display system has been designed at Bhabha Atomic Research Centre. It is proposed to be used as a part of emergency preparedness and response programme at the nuclear facility sites. As per the design made for Bhabha Atomic Research Centre, Trombay site, each plant or area in the site is identified by a unique identification code. The main Site Emergency Control Centre/Emergency Response Centre at Mod. Labs. selectively calls the various plants and declares the nature of emergency to be followed In that plant/area through different siren signals along with display and announcement of instructions. This paper describes the details of the system that is designed for Bhabha Atomic Research Centre, Trombay site and proposed for other nuclear power plant sites. (author)

    In China, fireworks are an integral part of the celebration of the annual Spring Festival, but the number of injuries associated with their private use seen in emergency rooms increases dramatically. To raise awareness and help guide future prevention practices in this city, we investigated the epidemiology of firework-related injuries presented at our trauma and burn center in Beijing during the Spring Festivals of 2007-2011. Patients were interviewed using a pre-coded questionnaire to elicit information regarding age, gender, causes, injured body part, type of injury, diagnosis, and disposition. From 2007 to 2011, during the Spring Festivals 734 patients with fire-work related injuries were seen at our trauma and burn center in Beijing, the median patients of the five year were 140(136-150). The mean age of the patients was 26±15.3 years (range, 1-95 years). Of the 734 patients, the highest proportion of injuries were the 5-14 year-old age group The majority of the patients were male (87.9%), the overall male:female ratio was 7.41:1, and males were predominant in all age groups. For all 5 years, the incidence of firework-related injuries during the Spring Festival Holidays peaked specifically on the first, fifth, and last days, respectively. Injuries were mainly due to improper handling (415/610, 68.0%) or setting off illegal fireworks (195/610, 32.0%). The most frequently injured body parts were the hands and fingers (32.0%), head or face except eyes (28.3%), and trunk (22.4%). Burns were the most common type of injury (65.7%), most of the burned patients (437/453) were between 1% and 10%, and the most common region burned were hands and fingers (218/754). Contusions or lacerations were the second common type of injury (34.3%). Most of the patients (642, 87.5%) were treated and released, while 37 (5%) were treated and transferred, and 55 (7.5%) were admitted for advanced treatment. The private use of fireworks during the Spring Festival Holidays is associated

    VLT Image of Supernova in Beautiful Spiral Galaxy NGC 1288 Stars do not like to be alone. Indeed, most stars are members of a binary system, in which two stars circle around each other in an apparently never-ending cosmic ballet. But sometimes, things can go wrong. When the dancing stars are too close to each other, one of them can start devouring its partner. If the vampire star is a white dwarf - a burned-out star that was once like our Sun - this greed can lead to a cosmic catastrophe: the white dwarf explodes as a Type Ia supernova. In July 2006, ESO's Very Large Telescope took images of such a stellar firework in the galaxy NGC 1288. The supernova - designated SN 2006dr - was at its peak brightness, shining as bright as the entire galaxy itself, bearing witness to the amount of energy released. ESO PR Photo 39/07 ESO PR Photo 39/07 SN 2006dr in NGC 1288 NGC 1288 is a rather spectacular spiral galaxy, seen almost face-on and showing multiple spiral arms pirouetting around the centre. Bearing a strong resemblance to the beautiful spiral galaxy NGC 1232, it is located 200 million light-years away from our home Galaxy, the Milky Way. Two main arms emerge from the central regions and then progressively split into other arms when moving further away. A small bar of stars and gas runs across the centre of the galaxy. The first images of NGC 1288, obtained during the commissioning period of the FORS instrument on ESO's VLT in 1998, were of such high quality that they have allowed astronomers [1] to carry out a quantitative analysis of the morphology of the galaxy. They found that NGC 1288 is most probably surrounded by a large dark matter halo. The appearance and number of spiral arms are indeed directly related to the amount of dark matter in the galaxy's halo. The supernova was first spotted by amateur astronomer Berto Monard. On the night of 17 July 2006, Monard used his 30-cm telescope in the suburbs of Pretoria in South Africa and discovered the supernova as an

    Spherical display systems, also known as digital globes, are technologies that, in person or online, can be used to help visualize global datasets and earth system processes. Using the InterRidge Global Database of Active Submarine Hydrothermal Vent Fields and imagery from deep-sea vehicles, we are creating content for spherical display systems to educate and excite the public about dynamic geophysical and biological processes and exploration in the deep ocean. The 'Global Viewport for Virtual Exploration of Deep-Sea Hydrothermal Vents' is a collaboration between the Woods Hole Oceanographic Institution and the Ocean Explorium at New Bedford Seaport, hosting a Magic Planet and Science On a Sphere (SOS), respectively. The main activities in the first year of our project were geared towards team building and content development. Here we will highlight the partnering and teamwork involved in creating and testing the effectiveness of our new content. Our core team is composed of a lead scientist, educators at both institutions, graphic artists, and a professional evaluator. The new content addresses key principles of Earth Science Literacy and Ocean Literacy. We will share the collaborative, iterative process by which we developed two educational pieces, 'Life without sunlight' and 'Smoke and fire underwater' - each focusing on a different set of 3 literacy principles. We will share how we conducted our front-end and formative evaluations and how we focused on 2 NSF Informal Education Impact Categories for our evaluation questionnaire for the public. Each educational piece is being produced as a stand-alone movie and as an interactive, docent-led presentation integrating a number of other datasets available from NOAA's SOS Users Network. The proximity of our two institutions enables a unique evaluation of the learning attained with a stand-alone spherical display vs. live presentations with an SOS.

    Full Text Available Modern real world science and engineering problems can be classified as multi-objective optimisation problems which demand for expedient and efficient stochastic algorithms to respond to the optimization needs. This paper presents an object-oriented software application that implements a firework optimization algorithm for function optimization problems. The algorithm, a kind of parallel diffuse optimization algorithm is based on the explosive phenomenon of fireworks. The algorithm presented promising results when compared to other population or iterative based meta-heuristic algorithm after it was experimented on five standard benchmark problems. The software application was implemented in Java with interactive interface which allow for easy modification and extended experimentation. Additionally, this paper validates the effect of runtime on the algorithm performance.

    Fiedrich, M.; Kurtenbach, R.; Wiesen, P.; Kleffmann, J.

    2017-09-01

    In several previous studies emission of ozone (O3) during fireworks has been reported, which was attributed to either photolysis of molecular oxygen (O2) or nitrogen dioxide (NO2) by short/near UV radiation emitted during the high-temperature combustion of fireworks. In contrast, in the present study no O3 formation was observed using a selective O3-LOPAP instrument during the combustion of pyrotechnical material in the laboratory, while a standard O3 monitor using UV absorption showed extremely high O3 signals. The artificial O3 response of the standard O3 monitor was caused by known interferences associated with high levels of co-emitted VOCs and could also be confirmed in field measurements during New Year's Eve in the city of Wuppertal, Germany. The present results help to explain unreasonably high ozone levels documented during ambient fireworks, which are in contradiction to the fast titration of O3 by nitrogen monoxide (NO) in the night-time atmosphere.

    A unique toy firework called sparkling fireworks is popular in Japan for 400 years, but the physics behind the beauty remains a hidden mystery. Sparkling fireworks are made by a twisted paper simply wrapping 0.1g of black powder at the lower end. Ignited there, the powder melts in a fireball of molten salts, and streaks of light are ejected. The beautiful fragile streaks are visible from the black body radiation of the hot surface of the ejected droplets. The droplets suddenly fragment up to ten times successively and their light streaks traces are like pine needles. We have already clarified why the droplets are ejected through the bursting of a gas bubble on the mother fireball, leading to successive fragmentations by micro explosions. To quantify phenomenon, we measure the diameter and the ejection velocity of the droplets. It is found that not only inertia and capillarity of the liquid matter, but also its viscosity is important (the Ohnesorge number is about 0.1). The droplets ejection velocity is determined by the liquid surface tension and viscosity, and separate from the mother drop on a visco-capillarity time scale.

    To analyse the demographic data, clinical characteristics, management and prognosis of patients with firework-related eye injuries. A retrospective review was performed of patients with eye injuries related to fireworks referred to TianJin Eye Hospital in North China from 2008 to 2013. Demographic information, clinical features, management and visual outcome were analysed and prognosis factors were evaluated. Ninety-nine patients (86 men) with 118 eye injuries were enrolled in the study. The average age of the patients was 32.0±20.5 years; 70/99 (70.7%) were aged >20 years. Eighty-one of the patients had been lighting the fireworks while the rest were bystanders. The main ophthalmic manifestations were hyphaema, vitreous haemorrhage, corneal/sclera/corneoscleral open globe injury, eyelid laceration, traumatic cataract, retinal/choroid detachment, endophthalmitis and intraocular foreign body (IOFB). Ninety patients required surgical intervention including repair of open globe injury, vitrectomy, cataract extraction and enucleation. 56/118 eyes (47.5%) received multiple operations. After treatment, final best-corrected visual acuity (BCVA) significantly improved (p=0.015). Some factors were significantly correlated with better final BCVA, including initial BCVA (p=0.036), closed globe injury (p=0.031), absence of endophthalmitis (p=0.014), absence of IOFB (p=0.024) and absence of retinal detachment (p=0.046). Firework-related eye injuries mainly occur in adult men and result in severe visual damage. The most common clinical manifestations are hyphaema and vitreous haemorrhage. Better initial BCVA and closed globe injury have a better visual result while endophthalmitis, IOFB and retinal detachment have a negative visual outcome. Improved eye protection, along with enhanced public education and legal ban on fireworks, could reduce the incidence of eye injuries. Published by the BMJ Publishing Group Limited.

    2016-06-01

    In the Netherlands, it is a tradition of setting off fireworks to celebrate the turn of the year. In our medical facility, each year patients with severe skeletal maxillofacial trauma inflicted by recreational fireworks are encountered. We present two cases of patients with severe blast injury to the face, caused by direct impact of rockets, and thereby try to contribute to the limited literature on facial blast injuries, their treatment, and clinical outcome. These patients require multidisciplinary treatment, involving multiple reconstructive surgeries, and the overall recovery process is long. The severity of these traumas raises questions about the firework traditions and legislations not only in the Netherlands but also worldwide. Therefore, the authors support restrictive laws on personal use of fireworks in the Netherlands.

    During a 5-year period, out of 110066 children with injuries recorded in the Greek Emergency Department Injury Surveillance System (EDISS), 91 had firework-related injuries. Descriptive analyses and the Barrell matrix were used to determine risk factors and extrapolated national firework childhood injury figures were calculated. The estimated annual incidence of childhood firework injuries treated in the emergency departments of hospitals countrywide, was 7 per 100000 children years. Seventy percent of injuries concerned older children (10-14 years), mostly boys with self-inflicted injuries, whereas girls suffered injuries as bystanders. A sharp peak in spring was noted, when the Greek Orthodox Easter is celebrated. Illicitly sold fireworks caused most injuries, but in eight instances homemade firecrackers were responsible.

  13. Firework related injury and legislation: the epidemiology of firework injuries and the effect of legislation in Northern Ireland.

    Fogarty, B J; Gordon, D J

    1999-02-01

    The efficacy of legislation in reducing firework associated injuries is uncertain as is the nature of the problem within the United Kingdom (UK). In September 1996 the legislation governing firework sale in Northern Ireland was relaxed thus equalling that of the rest of the UK. For the 2 years following the change in legislation we prospectively assessed those patients who were admitted with a firework injury over the Halloween period. We then compared these results with retrospective data for the 3 years prior to the change in firework law. In the pre-legislation series the mean number of patients admitted annually was 0.38 per 100,000 while in the post-legislation series the mean was 0.43 per 100,000. Blast injury to the hand was the commonest injury accounting for 53% of cases in both series. Burn injuries were the second commonest form of injury comprising 30% of all admissions. Of those admitted with a hand injury 47% had at least one finger terminalised and nearly half of those patients admitted with burns (44%) required skin grafting. We conclude that early evidence suggests that liberalisation of the law on firework sale has not resulted in a significant increase in firework related injuries requiring hospital admission.

    Mistaken ingestion of all manner of toxic matter is common in childhood, but poisoning with fireworks and matchsticks is rare. Fireworks usually contain 10% yellow phosphorus and 50% potassium chlorate. Potassium chlorate is an extremely reactive and toxic agent that is used in fireworks and matchstick heads. Eleven cases (7 females and 5 males; median age, 36 months [ranging from 24 to 48 months]) of poisoning after ingestion of fireworks and matchstick(s), between February 2008 and June 2014, were reviewed. The most common initial symptom was vomiting except for 2 cases in this group. Biochemical tests indicated that hyperphosphatemia was present in all patients, 8 patients (72.7%) had subclinical hepatic injury, 1 (9%) had acute hepatic failure, and 2 patients had no clinical or biochemical evidence of hepatic damage. Three patients had renal impairment, but none of them required dialysis. All of the patients recovered with supportive therapy except for 2 cases. One patient underwent cadaveric liver transplantation, whereas the other died because of circulatory dysfunction and respiratory failure due to pulmonary alveolar hemorrhage. Without prompt intervention, poisoning with fireworks carries high morbidity and mortality in children. It can cause pulmonary hemorrhage, in addition to other organ damage, including liver and kidney. Hyperphosphatemia is common, as it was seen in all of the study patients.

    Astronomers at The Newark Museum's Alice and Leonard Dreyfuss Planetarium teamed up with the New Jersey Institute of Technology's (NJIT) Center for Solar-Terrestrial Research (CSTR) and the Big Bear Solar Observatory in presenting Solar Fireworks. The exhibit opened on May 15, 2004 and features two exhibition kiosks with interactive touch screen displays, where students and other visitors can take "virtual tours" in the fields of solar physics, solar activity, Sun-Earth connection, and geo-sciences. Planetarium and museum visits are an integral part of the introductory physics and astronomy classes at NJIT and the exhibition has been integrated in the astronomy curriculum. For example, NJIT students of the Astronomy Club and regular astronomy courses were closely involved in the design and development of the exhibit. The exhibit is the latest addition to the long-running natural science exhibit "Dynamic Earth: Revealing Nature's Secrets" at the museum. More than 30,000 people per year attend various programs offered by the planetarium including public shows, more than a dozen programs for school groups, after school activities, portable planetarium outreach, outdoor sky watches, solar observing and other family events. More than 1,000 high school students visited the planetarium in 2004. The exhibit is accompanied by a yearly teacher workshop (the first one was held on October 18-20, 2004) to enhance the learning experience of classes visiting the Newark Museum. The planetarium and museum staff has been working with teachers of Newark high schools and has presented many workshops for educators on a wide range of topics from astronomy to zoology. At the conclusion of the exhibit in December 2005, the exhibit will go "on the road" and will be made available to schools or other museums. Finally, the exhibit will find its permanent home at the new office complex of CSTR at NJIT. Acknowledgements: Solar Fireworks was organized by The Newark Museum and the New Jersey

    2017-10-01

    Intelligent algorithms have been widely applied to portfolio optimization problems. In this paper, we introduce a novel intelligent algorithm, named fireworks algorithm, to solve the mean-VaR/CVaR model for the first time. The results show that, compared with the classical genetic algorithm, fireworks algorithm not only improves the optimization accuracy and the optimization speed, but also makes the optimal solution more stable. We repeat our experiments at different confidence levels and different degrees of risk aversion, and the results are robust. It suggests that fireworks algorithm has more advantages than genetic algorithm in solving the portfolio optimization problem, and it is feasible and promising to apply it into this field.

  6. Unusual presentation of firework injury causing intraoral burns

    Full Text Available Fireworks are commonly used in celebrate festive occasions. We present a case of an unusual presentation of intraoral firework injury, which is a very rare case. A fifteen year old boy kept four explosive papercaps wrapped in a small polythene bags in between his left molars and crushed them. This resulted in a contused lacerated wound over the left buccal mucosa. Patient was treated conservatively with maintenance of intraoral hygiene, antibiotics, proteolytic enzymes and analgesics. It took 18 days for complete healing of the wound.

    Diwali-specific firework induced particle pollution was measured in terms of aerosol mass loading, type, optical properties and vertical distribution. Entire nation exhibited an increase in particulate concentrations specifically in Indo-Gangetic Plain (IGP). Aerosol surface mass loading at middle IGP revealed an increase of 56-121% during festival days in comparison to their background concentrations. Space-borne measurements (Aqua and Terra-MODIS) typically identified IGP with moderate to high AOD (0.3-0.8) during pre-festive days which transmutes to very high AOD (0.4-1.8) during Diwali-day with accumulation of aerosol fine mode fractions (0.3-1.0). Most of the aerosol surface monitoring stations exhibited increase in PM2.5 especially on Diwali-day while PM10 exhibited increase on subsequent days. Elemental compositions strongly support K, Ba, Sr, Cd, S and P to be considered as firework tracers. The upper and middle IGP revealed dominance of absorbing aerosols (OMI-AI: 0.80-1.40) while CALIPSO altitude-orbit-cross-section profiles established the presence of polluted dust which eventually modified with association of smoke and polluted continental during extreme fireworks. Diwali-specific these observations have implications on associating fireworks induced particle pollution and human health while inclusion of these observations should improve regional air quality model.

    Federal agencies are made responsible for managing the historic properties under their jurisdiction by the National Historic Preservation Act of 1966, as amended. A component of this responsibility is to mitigate the effect of a federal undertaking on historic properties through mitigation often through documentation. Providing public access to this documentation has always been a challenge. To address the issue of public access to mitigation information, personnel from Argonne National Laboratory created the Box Digital Display Platform, a system for communicating information about historic properties to the public. The platform, developed for the US Army Dugway Proving Ground, uses short introductory videos to present a topic but can also incorporate photos, drawings, GIS information, and documents. The system operates from a small, self-contained computer that can be attached to any digital monitor via an HDMI cable. The system relies on web-based software that allows the information to be republished as a touch-screen device application or as a website. The system does not connect to the Internet, and this increases security and eliminates the software maintenance fees associated with websites. The platform is designed to incorporate the products of past documentation to make this information more accessible to the public; specifically those documentations developed using the Historic American Building Survey/ Historic American Engineering Record (HABS/HAER) standards. Argonne National Laboratory’s Box Digital Display Platform can assist federal agencies in complying with the requirements of the National Historic Preservation Act.

    Significant illness is associated with biological contaminants in drinking water, but little is known about health effects from low levels of chemical contamination in drinking water. To examine these effects in epidemiological studies, the sources of drinking water of study populations need to be known. The California Environmental Health Tracking Program developed an online application that would collect data on the geographic location of public water system (PWS) customer service areas in California, which then could be linked to demographic and drinking water quality data. We deployed the Water Boundary Tool (WBT), a Web-based geospatial crowdsourcing application that can manage customer service boundary data for each PWS in California and can track changes over time. We also conducted a needs assessment for expansion to other states. The WBT was designed for water system operators, local and state regulatory agencies, and government entities. Since its public launch in 2012, the WBT has collected service area boundaries for about 2300 individual PWS, serving more than 90% of the California population. Results of the needs assessment suggest interest and utility for deploying such a tool among states lacking statewide PWS service area boundary data. Although the WBT data set is incomplete, it has already been used for a variety of applications, including fulfilling legislatively mandated reporting requirements and linking customer service areas to drinking water quality data to better understand local water quality issues. Development of this tool holds promise to assist with outbreak investigations and prevention, environmental health monitoring, and emergency preparedness and response.

  14. COLORFUL FIREWORKS FINALE CAPS A STAR'S LIFE

    Science.gov (United States)

    2002-01-01

    Glowing gaseous streamers of red, white, and blue -- as well as green and pink -- illuminate the heavens like Fourth of July fireworks. The colorful streamers that float across the sky in this photo taken by NASA's Hubble Space Telescope were created by one of the biggest firecrackers seen to go off in our galaxy in recorded history, the titanic supernova explosion of a massive star. The light from the exploding star reached Earth 320 years ago, nearly a century before our United States celebrated its birth with a bang. The dead star's shredded remains are called Cassiopeia A, or 'Cas A' for short. Cas A is the youngest known supernova remnant in our Milky Way Galaxy and resides 10,000 light-years away in the constellation Cassiopeia, so the star actually blew up 10,000 years before the light reached Earth in the late 1600s. This stunning Hubble image of Cas A is allowing astronomers to study the supernova's remains with great clarity, showing for the first time that the debris is arranged into thousands of small, cooling knots of gas. This material eventually will be recycled into building new generations of stars and planets. Our own Sun and planets are constructed from the debris of supernovae that exploded billions of years ago. This photo shows the upper rim of the supernova remnant's expanding shell. Near the top of the image are dozens of tiny clumps of matter. Each small clump, originally just a small fragment of the star, is tens of times larger than the diameter of our solar system. The colors highlight parts of the debris where chemical elements are glowing. The dark blue fragments, for example, are richest in oxygen; the red material is rich in sulfur. The star that created this colorful show was a big one, about 15 to 25 times more massive than our Sun. Massive stars like the one that created Cas A have short lives. They use up their supply of nuclear fuel in tens of millions of years, 1,000 times faster than our Sun. With their fuel exhausted, heavy

  15. The non-display of authentic distress: public-private dualism in young people's discursive construction of self-harm.

    Science.gov (United States)

    Scourfield, Jonathan; Roen, Katrina; McDermott, Elizabeth

    2011-07-01

    This article draws from focus groups and interviews investigating how young people talk about self-harm. Some of the research participants had personal experience of self-harm but this was not a prerequisite for their inclusion in the study. Thematic coding was used initially to organise and give an overview of the data, but the data were subsequently analysed using a discourse analytic approach. The article focuses on the young people's constructions of deliberate self-harm such as 'cutting'. Throughout the focus groups and interviews, a dichotomy was set up by the young people between authentic, private self-harm which is rooted in real distress (and warrants a sympathetic response) and public, self-indulgent attempts to seek attention. This dualistic construction is discussed in some detail and located in various socio-cultural contexts. It is argued that the dualism illustrates contemporary ambivalence about mental health and youth. © 2011 The Authors.

  7. The epidemiology of firework-related injuries in the United States: 2000-2010.

    Science.gov (United States)

    Moore, Justin Xavier; McGwin, Gerald; Griffin, Russell L

    2014-11-01

    The purpose of this study is to examine the epidemiology of firework-related injuries among an emergency department (ED) nationally representative population of the United States for the years 2000-2010, including whether the type of firework causing the injury is differential by patient demographics and whether the severity of injury is associated with the firework type. The data analysed in this study was collected from the Consumer Product Safety Commission's (CPSC's) National Electronic Injury Surveillance System (NEISS). A total of 2812 injuries represented an estimated 97,562 firework-related injuries treated in emergency departments within the United States from 2000 to 2010. The incidence generally decreased over time. With respect to age, the rate was higher for children, with the highest rates being observed for 10-19 year olds (7.28 per 100,000 persons) and 0-9 year olds (5.45 per 100,000 persons). The injury rate was nearly three times higher for males compared to the female counterparts (4.48 vs. 1.57 per 100,000 persons). Females were less likely than males to severely injure themselves with all types of fireworks besides sparklers/novelty devices (OR 1.08, CI 0.26-4.38). The results from this suggest that firework-related injuries have decreased by nearly 30% over the 11-year period between 2000 and 2010. Moreover, there has been a decreasing trend in the type of firework causing injury for every firework type excluding the unspecified firework type. However, adolescents of 10-19 years old had the highest rate of injury for fireworks over the 11-year period. In addition odds of injury are differential by firework type. Understanding the specific types of fireworks may lead to better preventative methods and regulations. Moreover, preventative methods should be taken to reduce the rate of firework-related injuries among U.S. youths [1], and possibly more regulations and enforcement of laws geared towards prohibiting novice use of fireworks.

    2014-09-01

    Fireworks combusted during New Year's Eve festivities can cause different eye traumas which often need complex reconstructive surgery. It was our aim to systematically analyse these eye trauma cases which were treated at our clinic during the last eight years. Age, gender, side, trauma mechanism, treatment methods and outcome were analysed for all eye trauma cases caused by fireworks during the New Year's Eve celebrations from 2006 to 2013. For statistical analysis all trauma cases were divided into two groups of major and non-major eye trauma. The total number of patients treated was 122 (28 women, 94 men, mean age 26.2±13.0 years) with 137 traumatised eyes (77 right, 60 left). 24.6% of patients were ≤18 years of age. 76.2% were bystanders. 50 eyes from 46 patients (37.7%) suffered from major eye trauma. 26 patients (21.3%) were hospitalised. 8 eyes (5.8%) suffered from a penetrating injury or globe rupture and underwent primary reconstructive surgery. Further 16 eyes (11.7%) suffered from major eye trauma without open globe injury. In the aftermath 11 eyes (8.0%) went blind (visual acuityfireworks. However older patients suffer from major eye trauma more often. More education and prophylaxis of eye trauma caused by fireworks is desirable. Georg Thieme Verlag KG Stuttgart · New York.

  9. Event Displays for the Visualization of CMS Events

    CERN Document Server

    Jones, Christopher Duncan

    2010-01-01

    During the last year the CMS experiment engaged in consolidation of its existing event display programs. The core of the new system is based on the Fireworks event display program which was by-design directly integrated with the CMS Event Data Model (EDM) and the light version of the software framework (FWLite). The Event Visualization Environment (EVE) of the ROOT framework is used to manage a consistent set of 3D and 2D views, selection, user-feedback and user-interaction with the graphics windows; several EVE components were developed by CMS in collaboration with the ROOT project. In event display operation simple plugins are registered into the system to perform conversion from EDM collections into their visual representations which are then managed by the application. Full event navigation and filtering as well as collection-level filtering is supported. The same data-extraction principle can also be applied when Fireworks will eventually operate as a service within the full software framework.

The Event Visualization Environment (EVE) of the ROOT framework is used to manage a consistent set of 3D and 2D views, selection, user-feedback and user-interaction with the graphics windows; several EVE components were developed by CMS in collaboration with the ROOT project. In event display operation simple plugins are registered into the system to perform conversion from EDM collections into their visual representations which are then managed by the application. Full event navigation and filtering as well as collection-level filtering is supported. The same data-extraction principle can also be applied when Fireworks will eventually operate as a service within the full software framework.

    Full Text Available The effect of large-scale firework events on urban background trace metal concentrations was investigated using 24 hr data collected over 3 days at three sites in Busan Metropolitan City, Republic of Korea, during the falls (Oct. of 2011–2013. The firework events increased local background concentrations of trace metals as follows: K (1.72 times, Sr (2.64 times, As (2.86 times, Pb (2.91 times, and Al (5.44 times. The levels of some metals did not always drop to background level one day after the firework event. The contribution of fireworks to trace metal concentration levels (and emissions for 2011 event was negligible compared to 2012 and 2013 events due to different meteorological conditions (precipitation. In addition, the impact of firework events on the ambient concentration levels of trace metals was likely to be different depending on their chemical speciation. The impact of firework events in Busan on urban air quality (trace metal was less intense compared to other similar festivals worldwide. The largest emission of trace metals and elements from firework burning was represented by K (128–164 kg, followed by Pb, Cd, Cu, Mg, Ba, As, Al, Ga, Co, and Na.

    2001-02-01

    The case of a 46 year-old German man with upper aerodigestive burn by firework was reported. He presented with the symptoms and signs of upper airway obstruction. Tracheostomy was done and direct laryngoscopy with microscopic examination revealed swelling and denudation of the mucosa of the oral cavity and supraglottic area. Intravenous steroids and antibiotics were administrated for treatment. It is suggested that proper management needs an understanding of the mechanism and effect of the corrosive agent. Careful airway management resulted in a good outcome in this patient.

    2014-03-01

    Full Text Available In this paper, we investigate our mobility-assisted and adaptive broadcast routing mechanism, called Mobility Tolerant Firework Routing (MTFR, which utilizes the concept of potentials for routing and improves node reachability, especially in situations with high mobility, by including a broadcast mechanism. We perform detailed evaluations by simulations in a mobile environment and demonstrate the advantages of MTFR over conventional potential-based routing. In particular, we show that MTFR produces better reachability in many aspects at the expense of a small additional transmission delay and intermediate traffic overhead, making MTFR a promising routing protocol and feasible for future mobile Internet infrastructures.

    2017-12-01

    To study the impact of fireworks (FW) events on air quality, aerosol particles from FW displays were measured using a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) and collocated instruments during the Independence Day holiday 2017 in Albany, NY. Three FW events were identified through potassium ion (K+) signals in the mass spectra. The largest FW event signal measured at two different locations was the Independence Day celebration in Albany, with maximum aerosol concentrations of about 55 ug/m3 at the downtown site and 35 ug/m3 at the uptown site. The aerosol concentration peaked at the uptown site about 2 hours later than at the downtown site. FW events resulted in significant increases in both organic and inorganic (K+, sulfate, chloride) compounds. Among the organics, Positive Matrix Factorization (PMF) identified one special FW organic aerosol factor (FW-OA), which was highly oxidized. The intense emission of FW particles from the Independence Day celebration contributed 76% of total PM1 at the uptown site. The aerosol and wind LiDAR measurements showed two distinct pollution sources, one from the Independence Day FW event in Albany, and another aerosol source transported from other areas, potentially associated with other town's FW events.

    2010-12-01

    To provide a systematic review on ocular firework trauma with emphasis on incidence and patient demographics, the extent of ocular trauma and visual function loss, and firework regulation effects on injury rates. A literature search was performed using predetermined inclusion and exclusion criteria. Demographic characteristics of ocular firework casualties were obtained and incidence rates of sustained trauma and vision loss calculated. Twenty-six relevant articles were suitable for calculation of trauma incidence and patient demographics, of which 17 articles could be used for calculating trauma severity and vision loss. Victims were male (77%), young (82%) and often bystander (47%). Most of the trauma was mild and temporary. Penetrating eye trauma, globe contusions and burns accounted for 18.2%, with a 3.9% enucleation rate. Mean visual acuity was >10/20 in 56.8%, with severe vision loss (firework legislation show 87% less eye trauma (pfirework traumas show severe vision loss, mostly in young males. Bystanders are as frequently injured. Firework traumas are a preventable cause of severe ocular injury and blindness because countries using restrictive firework legislation have remarkable lower trauma incidence rates.

  17. Thermal analysis of pyrotechnic mixture-fireworks, atom-bomb

    Rajendran, Jeya; Thanulingam, T.L.

    2008-01-01

    Sound level produced from two varieties of sound producing fireworks of atom-bomb, cake bomb and thunder bomb were measured. The pyrotechnic mixture, KNO 3 /S/Al(H 3 BO 3 ) of compositions 57.5/19.9/22.1(0.5)% very much similar to commercial atom-bomb were taken and five cake bomb and seven thunder bomb with different net weight of chemicals were manufactured specifically for analysis. Cake bomb with 1g pyrotechnic mixture and thunder bomb with 2g pyrotechnic mixture produce -3 . Ignition temperature of the mixture is above the melting point of the metallic fuel, Al (660 deg C) and self propagating decomposition occurred at high temperature. The pyrotechnic mixture, KNO 3 /S/Al(H 3 BO 3 ) is a safe mixture from accidental factor, static electricity. DSC studies indicate slight formation of potassium nitrite with evolution of NO above 400 deg C. (author)

  18. The Firework of Electromagnetic Counterparts from GW170817

    2018-01-01

    The gravitational-wave signal of the binary neutron star merger GW170817 was followed by a firework of electromagnetic transients across the entire electromagnetic spectrum. The gamma-ray emission has provided strong evidence for the association of short gamma-ray bursts (SGRBs) with binary neutron star mergers and the ultraviolet, optical, and near-infrared emission is consistent with a kilonova indicative of the formation of heavy elements in the merger ejecta by the rapid neutron capture process (r-process). In this talk, I will discuss and review theoretical scenarios to interpret the gamma-ray, X-ray, and radio observations. I will present recent results from general-relativistic magnetohydrodynamic simulations and discuss possible scenarios and mass ejection mechanisms that can give rise to the observed kilonova features. In particular, I will argue that massive winds from neutrino-cooled post-merger accretion disks most likely synthesized the heavy r-process elements in GW170817.

  19. A double-blind placebo-controlled study into the efficacy of a homeopathic remedy for fear of firework noises in the dog (Canis familiaris).

    2008-07-01

    Seventy-five dogs that showed a fear response to fireworks participated in a double-blinded, placebo-controlled clinical trial to assess the efficacy of a homeopathic remedy for the alleviation of their behavioural signs. Dogs were randomly assigned to one of two treatments; the homeopathic treatment or the placebo treatment. At the baseline assessments the owners identified the behavioural signs of fear that their dogs normally displayed in response to fireworks, rated their frequency and intensity, and assessed the global severity of their dog's responses. These measures were repeated at the final assessment and owners also completed weekly diaries for the length of the trial. There were significant improvements in the owners' rating of 14/15 behavioural signs of fear in the placebo treatment group and all 15 behavioural signs in the homeopathic treatment group. Both treatment groups also showed significant improvement in the owners' rating of the global severity of their dog's responses. However, there was no significant difference in the response seen between the two treatment groups.

    In the production of fireworks, various pollutants including particles of metals and organic compounds are released into the environment. Although the adverse effects of these air pollutants are known, the impact on pregnant women residing in this area remains to be determined. The aim of this study was to examine the association between maternal exposure to fireworks production chemicals and frequency of preterm birth in Liuyang, China. Maternal exposure to fireworks production was estimated at the residential district level and assessed using factory density, which was defined as the number of fireworks factories per 1000 residents in each district. The association of maternal exposure to particulates released from fireworks production plants with frequency of preterm birth was determined using data obtained from a cohort study conducted in Liuyang, China. Data were analyzed utilizing linear regression and logistic regression. There was no significant association between factory density and spontaneous preterm or medically induced preterm birth. Unexpectedly, pregnant women residing in areas with higher density of fireworks factories were at a reduced risk of preterm premature rupture of membranes (PPROM). Data demonstrated that residential density of fireworks factories appeared to be negatively correlated with preterm birth rate as evidenced by PPROM. At present, it is difficult to reconcile the inverse relationship between firework chemical exposure and frequency of preterm births as ambient particulate inhalation is known to adversely affect preterm birth occurrence.

  2. The FireWork air quality forecast system with near-real-time biomass burning emissions: Recent developments and evaluation of performance for the 2015 North American wildfire season.

    Environment and Climate Change Canada's FireWork air quality (AQ) forecast system for North America with near-real-time biomass burning emissions has been running experimentally during the Canadian wildfire season since 2013. The system runs twice per day with model initializations at 00 UTC and 12 UTC, and produces numerical AQ forecast guidance with 48-hr lead time. In this work we describe the FireWork system, which incorporates near-real-time biomass burning emissions based on the Canadian Wildland Fire Information System (CWFIS) as an input to the operational Regional Air Quality Deterministic Prediction System (RAQDPS). To demonstrate the capability of the system we analyzed two forecast periods in 2015 (June 2-July 15, and August 15-31) when fire activity was high, and observed fire-smoke-impacted areas in western Canada and the western United States. Modeled PM2.5 surface concentrations were compared with surface measurements and benchmarked with results from the operational RAQDPS, which did not consider near-real-time biomass burning emissions. Model performance statistics showed that FireWork outperformed RAQDPS with improvements in forecast hourly PM2.5 across the region; the results were especially significant for stations near the path of fire plume trajectories. Although the hourly PM2.5 concentrations predicted by FireWork still displayed bias for areas with active fires for these two periods (mean bias [MB] of -7.3 µg m(-3) and 3.1 µg m(-3)), it showed better forecast skill than the RAQDPS (MB of -11.7 µg m(-3) and -5.8 µg m(-3)) and demonstrated a greater ability to capture temporal variability of episodic PM2.5 events (correlation coefficient values of 0.50 and 0.69 for FireWork compared to 0.03 and 0.11 for RAQDPS). A categorical forecast comparison based on an hourly PM2.5 threshold of 30 µg m(-3) also showed improved scores for probability of detection (POD), critical success index (CSI), and false alarm rate (FAR).

    We studied the epidemiology of paediatric firework-related injury in the urban population of Delhi during the festival of lights (Diwali). In this prospective observational study, data were collected on the day of Diwali for two consecutive years, 2010 and 2011. All children with firework injuries coming to the emergency room were included in the study. Data were recorded in a predesigned proforma. Of the 65 cases, 75% were males and 25% were females; most children were more than 10 years of age and majority (90%) of them were unsupervised. Half (49%) of the cases were due to misuse of the fireworks or erratic behaviour, among which the most common observed mode was igniting cracker while holding it (18 cases; 24% of total injuries), which led to injuries to the hand and palm. Device failure was the next common cause for firework injuries, including unexpected blast of the crackers and string bomb as the most common. Overall, the most commonly injured body sites were hands (62%), face (32%) and eyes (10%). Crackers and string bomb mainly caused injuries to hands; fountains and gunpowder caused injuries to the face. Sixty (94%) children were managed conservatively and 5 (6%) required skin grafting and tendon repair. We recommend parental supervision especially for males, wearing non-synthetic and non-flowing clothes, promoting branded crackers and educational campaigns in schools to curtail the rising trend in firework-related injuries in the paediatric population. © 2013 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Fireworks or firecrackers can cause serious accidents. They are classified from K1 to K4 according to the amount of powder they contain. In Alsace (France), a type-K1 firecracker is available on the free market and the K2 and K3 ones are prohibited. The aim of this study was to reveal the effects of measures taken in order to prevent repercussions related to hand injuries caused by fireworks. Patients who fell victim to firework incidents have been recorded since 2006, starting date of the prevention campaign. Records have been taken on the circumstances, the group of firecracker, the level of injury and the severity of the injury in four stages. Our series included 62 hands from 58 patients (average age: 25 years), including two women. Most of them sustained their injury during the night of New Year's Eve. The study dealt with 21 K1, and 35 K2 or K3. We registered 29 cases of grade I, 2 grades II, 21 grades III and 9 grades IV. One patient died. The numbers of consultations, K2/K3 injuries and number of surgeries increased from 2006 to 2012. Our results show that firework-related injuries to the hand are serious, pluridigital, multistage and/or bilateral. Prevention was ineffective but should be improved and strengthened, as a total ban on fireworks is a counterproductive measure. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    2018-02-06

    As part of the NIH Library of Integrated Network-based Cellular Signatures (LINCS) program, hundreds of thousands of transcriptomic signatures were generated with the L1000 technology, profiling the response of human cell lines to over 20,000 small molecule compounds. This effort is a promising approach toward revealing the mechanisms-of-action (MOA) for marketed drugs and other less studied potential therapeutic compounds. L1000 fireworks display (L1000FWD) is a web application that provides interactive visualization of over 16,000 drug and small-molecule induced gene expression signatures. L1000FWD enables coloring of signatures by different attributes such as cell type, time point, concentration, as well as drug attributes such as MOA and clinical phase. Signature similarity search is implemented to enable the search for mimicking or opposing signatures given as input of up and down gene sets. Each point on the L1000FWD interactive map is linked to a signature landing page, which provides multifaceted knowledge from various sources about the signature and the drug. Notably such information includes most frequent diagnoses, co-prescribed drugs and age distribution of prescriptions as extracted from the Mount Sinai Health System electronic medical records (EMR). Overall, L1000FWD serves as a platform for identifying functions for novel small molecules using unsupervised clustering, as well as for exploring drug MOA. L1000FWD is freely accessible at: http://amp.pharm.mssm.edu/L1000FWD. avi.maayan@mssm.edu. Supplementary data are available at Bioinformatics online. © The Author (2018).

    Specific analytical procedures are requested for the forensic analysis of pre- and post-blast consumer firework samples, which present significant challenges. Up to date, vibrational spectroscopic techniques such as Fourier transform infrared spectroscopy (FTIR) have not been tested for the analysis of post-blast residues in spite of their interesting strengths for the forensic field. Therefore, this work proposes a simple and fast procedure for the sampling and analysis of consumer firework post-blast residues by a portable FTIR instrument with an Attenuated Total Reflection (ATR) accessory. In addition, the post-blast residues spectra of several consumer fireworks were studied in order to achieve the identification of their original chemical compositions. Hence, this work analysed 22 standard reagents usually employed to make consumer fireworks, or because they are related to their combustion products. Then, 5 different consumer fireworks were exploded, and their residues were sampled with dry cotton swabs and directly analysed by ATR-FTIR. In addition, their pre-blast fuses and charges were also analysed in order to stablish a proper comparison. As a result, the identification of the original chemical compositions of the post-blast samples was obtained. Some of the compounds found were potassium chlorate, barium nitrate, potassium nitrate, potassium perchlorate or charcoal. An additional study involving chemometric tools found that the results might greatly depend on the swab head type used for the sampling, and its sampling efficiency. The proposed procedure could be used as a complementary technique for the analysis of consumer fireworks post-blast residues. Copyright © 2015 Elsevier B.V. All rights reserved.

    Atmospheric pollution characteristics during fireworks burning time in 2009 Spring Festival in Quangzhou suburb were studied. Particulate aerosol has been monitored and collected using real-time monitor and middle-volume sampler during fireworks burning time. The objectives of this study were to identify the contents and distributing characteristics of particles, polycyclic aromatic hydrocarbon (PAHs) and water-soluble ions and to discuss sources of these pollutants. The results showed that PM2.5 and PM10 were increased significantly during fireworks burning time. The highest concentration of particles presented time of 00:57-01:27 on New Year's Eve, which the average concentration of PM2.5 and PM10 were reached 1102.43 microm(-3) and 1610.22 microg x m(-3) in 30 min. The concentration of particle- and gas-PAHs were 54.18 ng x m(-1) and 47.10 ng x m(-3), respectively, during fireworks burning time in New Year's Eve, which were higher than that in the normal day. It can be judged by the diagnostic ratios that the primary source of PAHs in Quanzhou suburb were the combustion of coal, biomass and the exhaust emission from diesel vehicles in this region. Results of water-soluble ions indicated that fireworks burning were the main reason to lead to higher concentration of these ions during Spring Festival. Moreover, pollution gases of NOx and SO2 that were origined from fireworks burning, coal combustion and exhaust emission from motor vehicle were supplied precursors to form secondary pollutants, such as NO3- and SO4(2-).

    To investigate the relationship between perceived risk and risk-taking behaviors during the Iranian Last Wednesday Eve Fireworks (ILWEF). A random sample of 2475 Tehranian households were asked on perceived risk of injury, risk-taking behaviors, experience of injuries, and their perception of ability to manage the harmful events during the ILWEF. Lower perceived injury risk and higher perceived ability of managing an injured household member were associated with participation in fireworks practice and incidence of injury. These findings can be of practical importance to increase safety during festivals by improving risk perception in the community.

    The possibility that a black hole could tunnel into to white hole has recently received attention. Here we present a metric that improves the "firework" metric: it describes the entire process and solves the Einstein's equations everywhere except on a small transition surface that corresponds to the quantum tunneling. We compute the corresponding ray-tracing map from past infinity to future infinity explicitly.

    Tobacco advertising and product promotions have been largely banned in the UK but point of sale (POS) tobacco advertising is one of the few places where tobacco products may be legitimately advertised. POS displays have been shown to increase susceptibility to smoking, experimentation and initiation into smoking. These displays may also influence perceived prevalence of smoking and the perception that tobacco products are easily obtained and are a 'normal' product. A ban of POS tobacco advertising was introduced in Scotland in large tobacco retail outlets of over 280 m2 internal sales floor areas (mainly supermarkets) in April 2013 and will be extended to include smaller tobacco retail outlets in April 2015. However, the impact of POS bans on smoking attitudes, behaviours and prevalence has yet to be determined. This study has a multi-modal before and after design and uses mixed methods to collect data, at baseline and then with longitudinal follow-up for 4 years, in four purposively selected communities. For the purposes of the study, community is defined as the catchment areas of the secondary schools selected for study. There are four main components to the on-going study. In each of the four communities, at baseline and in follow-up years, there will be: mapping and spatial analyses of tobacco retail outlets; tobacco advertising and marketing audits of tobacco retail outlets most used by young people; cross-sectional school surveys of secondary school pupils; and focus group interviews with purposive samples of secondary school pupils. The tobacco audit is supplemented by interviews and observations conducted with a panel of tobacco retailers recruited from four matched communities.

    2017-09-01

    Full Text Available Paintings in museums might occasionally be replaced by a photoprint mimicking the original. This article is an investigation of what constitutes a good reproduction of an artwork (oil painting that is meant to be displayed. The article discusses what the usefulness of reproductions depends on, applying the Valuation Studies approach, which means the primary concern is with the practice of valuing itself. In other words, the study focuses on how museum experts evaluate reproduc-tions of oil paintings. The article analyses three cases of displaying digitally prin-ted copies of Edvard Munch's oil paintings between 2013 and 2015 in the Munch Museum and in the National Gallery in Oslo. The study is based on a series of semi-structured interviews with the experts, working at and for the museums, that were involved in producing and exhibiting of the photoprints: curators, con-servators, museum educators, and external manufacturers. The interviews were grouped into five clusters, which I have chosen to call registers of valuing following Frank Heuts and Annemarie Mol (2013. The described valuation practices have to do with delivering experiences to the public, obtaining mimetic resemblance, solving ethical aspects, exhibitions' budget, and last but not least, with the time perspective.

    Fireworks are the leading cause of injuries such as burns and amputations during the Persian Wednesday Eve Festival (Chaharshanbeh Soori). This study was designed to explore the age of the high-risk population, the type of fireworks most frequently causing injury, the pattern of injury, and the frequency of permanent disabilities. This cohort study was performed by Tehran Emergency Medical Services at different medical centers all around Tehran, Iran, in individuals referred due to firework-related injuries during 1 month surrounding the festival in the year 2007. The following information was extracted from the patients' medical records: demographic data, the type of fireworks causing injury, the pattern and severity of the injury, the pre-hospital and hospital care provided for the patient, and the patient's condition at the time of discharge. In addition, information on the severity of the remaining disability was recorded 8 months after the injury. There were 197 patients enrolled in the study with a mean age of 20.94 ± 11.31 years; the majority of them were male. Fuse-detonated noisemakers and homemade grenades were the most frequent causes of injury. Hand injury was reported in 39.8% of the cases. Amputation and long-term disability were found in 6 and 12 cases, respectively. None of the patients died during the study period. The fireworks used during a Chaharshanbe Soori ceremony were responsible for a considerable number of injuries to different parts of the body, and some of them led to permanent disabilities.

    2015-12-01

    Based on data from the air quality monitoring stations in the Pearl River Delta during the 2015 Spring Festival, the regional air quality was investigated and the impact of burning fireworks on urban air quality was assessed. The results showed that: Zhaoqing was the worst polluted city in PM₁₀, PM₂.₅, SO₂ and CO in terms of concentrations in the region during the period, Huizhou was the worst polluted city in O₃ and Guangzhou was the most polluted city in NO₂ at the same time. Compared to the data of last year, the SO₂, NO₂, CO, PM₁₀ and PM₂.₅ concentrations had decreased significantly, but the O₃ concentration had increased during the Spring Festival. Burning fireworks during the Spring Festival were mainly concentrated in the suburbs. The concentrated discharge of fireworks made the SO₂, PM₁₀ and PM₂.₅ concentrations increased significantly in the New Year's Eve night, even multiplied, but had no significant effect on CO, O₃ and NO₂. The rapid decline in PM₂.₅/PM₁₀ proportion was caused by the discharge of fireworks, and the ratio of PM₂.₅/PM₁₀ reached the minimum when concentration of particles reached the peak. By assessing, the maximum contribution of hourly concentration from burning fireworks in each city was between 16 µg · m⁻³ and 65 µg · m⁻³ for PM₂.₅, between 28 µg · m⁻³ and 138 µg · m⁻³ for PM₁₀ and between 9 µg · m⁻³ and 43 µg · m⁻³ for SO₂.

    Ambient respirable particles (PM ≤ 10 μm, denoted by PM(10)) were characterized with respect to 20 elements, 16 polycyclic aromatic hydrocarbons (PAHs), elemental and organic carbon (EC and OC) during a major firework event-the "Diwali" festival in Delhi, India. The event recorded extremely high 24-h PM(10) levels (317.2-616.8 μg m(-3), 6-12 times the WHO standard) and massive loadings of Ba (16.8 μg m(-3), mean value), K (46.8 μg m(-3)), Mg (21.3 μg m(-3)), Al (38.4 μg m(-3)) and EC (40.5 μg m(-3)). Elemental concentrations as high as these have not been reported previously for any firework episode. Concentrations of Ba, K, Sr, Mg, Na, S, Al, Cl, Mn, Ca and EC were higher by factors of 264, 18, 15, 5.8, 5, 4, 3.2, 3, 2.7, 1.6 and 4.3, respectively, on Diwali as compared to background values. It was estimated that firework aerosol contributed 23-33% to ambient PM(10) on Diwali. OC levels peaked in the post-Diwali samples, perhaps owing to secondary transformation processes. Atmospheric PAHs were not sourced from fireworks; instead, they correlated well with changes in traffic patterns indicating their primary source in vehicular emissions. Overall, the pollutant cocktail generated by the Diwali fireworks could be best represented with Ba, K and Sr as tracers. It was also found that chronic exposure to Diwali pollution is likely to cause at least a 2% increase in non-carcinogenic hazard index (HI) associated with Al, Mn and Ba in the exposed population.

    Supernovae (SNe) are the spectacularly violent deaths of evolved young massive stars, which expel a shock wave into the intergalactic medium that in turn can spark star formation and disperse heavy elements into their host galaxy. While a SN event can be classified by its spectral signature, determining the nature of a SN progenitor depends upon chance photometry taken prior to the event. By turning to the study of SN host environments and their surrounding interstellar medium within the unique and rare population of galaxies that have hosted three or more SN events within the last century, we are granted the opportunity to study the locations and environmental properties of stellar populations prone to supernova progenitor production. Using moderate-resolution optical slit spectra taken with the Apache Point Observatory 3.5m DIS spectrograph, our goal is to map metallicity, ionization parameter, and star formation rates using emission line diagnostic ratios across each SN-rich galaxy. Dubbed the “Fireworks Galaxy” at a distance of 5.6 ± 1.5 Mpc, NGC 6946 is of particular interest as it has uniquely produced ten core-collapse supernovae (CCSNe) and several other massive star transients within the last century. We present spatially-resolved metallicity and star formation rate (SFR) maps of NGC 6946, tracing fifty-five slit orientations which span the face of the galaxy and cover all CCSN host sites. Future work will include both stellar population synthesis modelling to determine stellar populations, ages, and SFR histories in NGC 6946 and a further expansion of this analysis to the other SN-rich host galaxies in our sample.

    Ocular trauma is a major cause of acquired monocular blindness in children. Firework injuries account for 20% of ocular trauma. The purpose of our study was to document the profile of ocular firework injuries in children during the festive season of Diwali and to determine the prevalence of unilateral blindness in them. A retrospective chart analysis of ocular firework injury in children during the festival of Diwali from 2009 to 2013, conducted in a tertiary care eye center in Tamil Nadu, Southern India. Children below 18 years of age with ocular firework injuries who presented to the emergency department for 3 consecutive days - the day of Diwali, 1 day before, and 1 day after Diwali - were included in this study. Eighty-four children presented with firework-related ocular injuries during the study period. Male to female ratio was 4:1 with mean age 9.48 ± 4 years. Forty-four percentage required hospitalization. The prevalence of unilateral blindness in children due to fireworks was found to be 8% (95% confidence interval - 2-13%). Vision 2020 gives high priority to avoidable blindness, especially in children. In our study, for every 12 children who presented with firecracker injury, one resulted in unilateral blindness. This is an avoidable cause of blindness. Awareness needs to be created, and changes in policy regarding sales and handling of firecrackers including mandatory use of protective eyewear should be considered.

    Public health policy is increasingly concerned with the care for victims of a disaster. This article describes the design and implementation of an epidemiological study, which seeks to match care services to the specific problems of persons affected by a large scale incident. The study was prompted by the explosion of a firework depot in Enschede, the Netherlands. All those directly affected by this incident (residents, emergency services personnel, and people who happened to be in the area at the time), some of whom suffered personal loss or injury. The project investigates both the physical and psychological effects of the disaster, as well as the target group's subsequent call on healthcare services. A questionnaire based follow up survey of those directly affected and an ongoing monitoring of health problems relying on reports from healthcare professionals. The follow up survey started three weeks after the incident and was repeated 18 months and almost four years after the incident. The monitoring is conducted over a four year period by general practitioners, the local mental health services department, occupational health services, and the youth healthcare services department. It provides ongoing information. The results of the study are regularly discussed with healthcare professionals and policy makers, and are made known to the research participants. The paper also explains the considerations that were made in designing the study to help others making up their research plans when confronted with possible health effects of a disaster.

    2016-01-01

    Artificial meteor trains generated by chemical releases by using sounding rockets flown in upper atmosphere were successfully observed by multiple sites on ground and from an aircraft. We have started the rocket experiment campaign since 2007 and call it "Space fireworks" as it illuminates resonance scattering light from the released gas under sunlit/moonlit condition. By using this method, we have acquired a new technique to derive upper atmospheric wind profiles in twilight condition as well as in moonlit night and even in daytime. Magnificent artificial meteor train images with the surrounding physics and dynamics in the upper atmosphere where the meteors usually appear will be introduced by using fruitful results by the "Space firework" sounding rocket experiments in this decade.

    Displays have several functions: to transmit images, to permit interaction, to quantitate features and to provide records. The main characteristics of displays used for image transmission are their resolution, dynamic range, signal-to-noise ratio and uniformity. Considerations of visual acuity suggest that the display element size should be much less than the data element size, and in current practice at least 256X256 for a gamma camera image. The dynamic range for image transmission should be such that at least 64 levels of grey (or equivalent) are displayed. Scanner displays are also considered, and in particular, the requirements of a whole-body camera are examined. A number of display systems and devices are presented including a 'new' heated object colour display system. Interaction with displays is considered, including background subtraction, contrast enhancement, position indication and region-of-interest generation. Such systems lead to methods of quantitation, which imply knowledge of the expected distributions. Methods for intercomparing displays are considered. Polaroid displays, which have for so long dominated the field, are in the process of being replaced by stored image displays, now that large cheap memories exist which give an equivalent image quality. The impact of this in nuclear medicine is yet to be seen, but a major effect will be to enable true quantitation. (author)

    To study the demographic profile, cause, type and severity of ocular injuries, their complications and final visual outcome following fireworks around the time of Deepawali in India. Case records of patients who presented with firework-related injuries during 2005-2009 at the time of Deepawali were reviewed. Data with respect to demographic profile of patients, cause and time of injury, time of presentation and types of intervention were analyzed. Visual acuity at presentation and final follow-up, anterior and posterior segment findings, and any diagnostic and surgical interventions carried out were noted. One hundred and one patients presented with firework-related ocular injuries, of which 77.5 % were male. The mean age was 17.60 ± 11.9 years, with 54 % being ≤14 years of age. The mean time of presentation was 8.9 h. Seventeen patients had open globe injury (OGI) and 84 had closed globe injury (CGI). Fountains were the most common cause of CGI and bullet bombs were the most common cause of OGI. Mean log MAR visual acuity at presentation was 0.64 and 1.22 and at last follow-up was 0.09 and 0.58 for CGI and OGI, respectively (p Firework injuries were seen mostly in males and children. Poor visual outcome was associated with poor initial visual acuity, OGI, IOFB, retinal detachment and development of endophthalmitis, while most patients with CGI regained good vision.

  20. PS-FW: A Hybrid Algorithm Based on Particle Swarm and Fireworks for Global Optimization

    Science.gov (United States)

    Chen, Shuangqing; Wei, Lixin; Guan, Bing

    2018-01-01

    Particle swarm optimization (PSO) and fireworks algorithm (FWA) are two recently developed optimization methods which have been applied in various areas due to their simplicity and efficiency. However, when being applied to high-dimensional optimization problems, PSO algorithm may be trapped in the local optima owing to the lack of powerful global exploration capability, and fireworks algorithm is difficult to converge in some cases because of its relatively low local exploitation efficiency for noncore fireworks. In this paper, a hybrid algorithm called PS-FW is presented, in which the modified operators of FWA are embedded into the solving process of PSO. In the iteration process, the abandonment and supplement mechanism is adopted to balance the exploration and exploitation ability of PS-FW, and the modified explosion operator and the novel mutation operator are proposed to speed up the global convergence and to avoid prematurity. To verify the performance of the proposed PS-FW algorithm, 22 high-dimensional benchmark functions have been employed, and it is compared with PSO, FWA, stdPSO, CPSO, CLPSO, FIPS, Frankenstein, and ALWPSO algorithms. Results show that the PS-FW algorithm is an efficient, robust, and fast converging optimization method for solving global optimization problems. PMID:29675036

    Directory of Open Access Journals (Sweden)

    James O. Butler

    2018-03-01

    Full Text Available This article provides a preliminary investigation into the naming practices of a unique product group: pyrotechnics. It is conducted through a comprehensive survey of units made available in the UK marketplace (of 2015 during peak seasonal availability (end of October through early November, when fireworks can easily be purchased from non-specialist retailers. The semantic content underpinning effective branding is shown as being predominantly focused on the sensory impact of the explosions, which provides the primary naming impetus. The analysis is conducted through a statistical assessment against thematic grouping — this approach is typical for the statistical assessment of brand names linguistic categorisation. The author introduces a range of twelve thematic categories that correspond to the semantic fields used as the associative basis for each name. This analysis features a dedicated assessment of two specific categories: Rockets (which provide a statistically-representative snapshot of the entire range and Sparklers (which were omitted from the quantitative data. The article shows that most often firework names are retrieved from military and cosmic thematic groups and point mainly to the expected visual effects. Besides providing relevant quantitative data, the paper demonstrates the qualitative linguistic versatility of firework names, arguing that they hold significant analytic opportunities for examining the role of associative semantics in the commercial naming of entertainment products.

    Full Text Available During Diwali festival, extensive burning of crackers and fireworks is made. Weeklong intensive observational campaign for aerosol study was carried out at a representative urban location in the eastern Indo-Gangetic Plain (IGP, Varanasi (25.3°N, 83.0°E, from October 29 to November 04, 2005 (Diwali on November 01, 2005, to investigate behavioral change of aerosol properties and radiative forcing between firework affected and nonaffected periods. Results show a substantial increase (~27% in aerosol optical depth, aerosol absorption coefficients, and aerosol scattering coefficients during affected period as compared to non-affected periods. Magnitudes of radiative forcing at top of atmosphere during affected and non-affected periods are found to be +10 ± 1 and +12 ± 1 Wm−2, respectively, which are −31 ± 7 and −17 ± 5 Wm−2, respectively, at surface. It suggests an additional cooling of ~20% at top of atmosphere, ~45% cooling at surface, and additional atmospheric heating of 0.23 Kday−1 during fireworks affected period, which is ~30% higher than the non-affected period average.

  20. JAVA Stereo Display Toolkit

    Science.gov (United States)

    Edmonds, Karina

    2008-01-01

    This toolkit provides a common interface for displaying graphical user interface (GUI) components in stereo using either specialized stereo display hardware (e.g., liquid crystal shutter or polarized glasses) or anaglyph display (red/blue glasses) on standard workstation displays. An application using this toolkit will work without modification in either environment, allowing stereo software to reach a wider audience without sacrificing high-quality display on dedicated hardware. The toolkit is written in Java for use with the Swing GUI Toolkit and has cross-platform compatibility. It hooks into the graphics system, allowing any standard Swing component to be displayed in stereo. It uses the OpenGL graphics library to control the stereo hardware and to perform the rendering. It also supports anaglyph and special stereo hardware using the same API (application-program interface), and has the ability to simulate color stereo in anaglyph mode by combining the red band of the left image with the green/blue bands of the right image. This is a low-level toolkit that accomplishes simply the display of components (including the JadeDisplay image display component). It does not include higher-level functions such as disparity adjustment, 3D cursor, or overlays all of which can be built using this toolkit.

When ingested, it shows its effects mainly in the liver, the kidneys, and the brain. A four-year-old girl had died as a result of acute hepatic failure caused by ingesting a firework cracker. The case showed high levels of hepatic enzymes, along with non-specific signs such as nausea, vomiting and diarrhea. Autopsy revealed diffuse microvesicular steatosis in the liver and disseminated degeneration in the proximal tubules of the kidneys. In cases with concomitant hepatorenal failure and cardiovascular collapse, death is inevitable. However, when only hepatic failure develops, hepatic transplantation may be lifesaving. Although intoxication from ingesting yellow phosphorus has a very high rate of mortality, forensic cases are extremely rare in the literature.

    With the rapid advances in telecommunications networks, mobile multimedia delivery to handsets is now a reality. While a truly immersive multimedia experience is still far ahead in the mobile world, significant advances have been made in the constituent audio-visual technologies to make this become possible. One of the critical components in multimedia delivery is the mobile handset display. While such alternatives as headset-style near-to-eye displays, autostereoscopic displays, mini-projectors, and roll-out flexible displays can deliver either a larger virtual screen size than the pocketable dimensions of the mobile device can offer, or an added degree of immersion by adding the illusion of the third dimension in the viewing experience, there are still challenges in the full deployment of such displays in real-life mobile communication terminals. Meanwhile, direct-view display technologies have developed steadily, and can provide a development platform for an even better viewing experience for multimedia in the near future. The paper presents an overview of the mobile display technology space with an emphasis on the advances and potential in developing direct-view displays further to meet the goal of enabling multimedia in the mobile domain.

    Laser Power Corporation has developed a new type of projection display, based upon microlaser technology and a novel scan architecture, which provides the foundation for bright, extremely high resolution images. A review of projection technologies is presented along with the limitations of each and the difficulties they experience in trying to generate high resolution imagery. The design of the microlaser based projector is discussed along with the advantage of this technology. High power red, green, and blue microlasers have been designed and developed specifically for use in projection displays. These sources, in combination with high resolution, high contrast modulator, produce a 24 bit color gamut, capable of supporting the full range of real world colors. The new scan architecture, which reduces the modulation rate and scan speeds required, is described. This scan architecture, along with the inherent brightness of the laser provides the fundamentals necessary to produce a 5120 by 4096 resolution display. The brightness and color uniformity of the display is excellent, allowing for tiling of the displays with far fewer artifacts than those in a traditionally tiled display. Applications for the display include simulators, command and control centers, and electronic cinema.

    An analog signal processor is described in this patent for connecting a source of analog signals to a cathode ray tube display in order to extend the dynamic range of the display. This has important applications in the field of computerised X-ray tomography since significant medical information, such as tumours in soft tissue, is often represented by minimal level changes in image density. Cathode ray tube displays are limited to approximately 15 intensity levels. Thus if both strong and weak absorption of the X-rays occurs, the dynamic range of the transmitted signals will be too large to permit small variations to be examined directly on a cathode ray display. Present tomographic image reconstruction methods are capable of quantising X-ray absorption density measurements into 256 or more distinct levels and a description is given of the electronics which enables the upper and lower range of intensity levels to be independently set and continuously varied.

    The effect of firework events on air quality was assessed from ambient fine particulate matter (PM2.5) collected during the Diwali period in two consecutive years, i.e., November 2015 and October 2016. The extensive firework activities led to the short-term degradation of air quality during the Diwali days. PM2.5 samples were chemically characterised for elements, water-soluble ionic species, organic carbon (OC) and elemental carbon (EC). Ba, K, Sr, S, Mg and Na showed significant increases in concentration on Diwali days compared to pre-Diwali days which revealed their association with firecrackers. Concentration of SO4 2-, NO3 -, Cl-, K+ and NH4 + ions contributed to the increases in PM2.5 concentration on Diwali days. Higher OC/EC ratios indicated the formation of secondary organic carbon during the Diwali period. This study concludes that the high PM2.5 level during Diwali 2016 was a result of contribution from fireworks on the Diwali night, trans-regional movement of pollutants due to crop residue burning, low wind speed (0.15 m s-1), and high humidity. It was observed that short-term exposure to Diwali is plausible to generate 1.3% increase in non-carcinogenic hazard index due to elements Al and Ba during Diwali 2016, whereas no significant variation was observed for the carcinogenic risk due to Pb. However, in 2015, the increase in non-carcinogenic hazard index was appreciably lower as compared to 2016.

    The chemical composition of Beijing aerosol was measured during summer and winter. Two distinct episodes were identified. Water-soluble potassium (K{sup +}) increased significantly during the firework episode in winter with an episode to non-episode ratio of 4.97, whereas the biomass burning (BB) episode in summer was characterized by high episode to non-episode ratios of levoglucosan (6.38) and K{sup +} (6.90). The BB and firework episodes had only a minor influence on the water-soluble OC (organic carbon) to OC ratio. Based on separate investigations of episode and non-episode periods, it was found that: (i) sulfate correlated strongly with both relative humidity and nitrate during the typical winter period presumably indicating the importance of the aqueous-phase oxidation of sulfur dioxide by nitrogen dioxide, (ii) oxalate and WSOC during both winter and summer in Beijing were mainly due to secondary formation, and (iii) high humidity can significantly enhance the formation potential of WSOC in winter. -- Highlights: • Two episodes were identified based on the chemical composition of Beijing aerosol. • Levoglucosan and K{sup +} increased significantly during the biomass burning episode. • The firework episode was characterized by high concentrations of K{sup +}. • WSOC and oxalate exhibited secondary nature during both summer and winter. • High humidity can significantly enhance the formation of WSOC in winter. -- This study suggests the benefits of investigating aerosol composition separately during episode and non-episode periods, and introducing organic tracers to the speciation measurements of PM{sub 2.5}.

    We report a rare case of traumatic injury to the eye caused by homemade fireworks in a Chinese juvenile patient with a metal ring left in the orbit after having been sutured at the Emergency Department. An 11-year-old boy presented with a traumatic injury to the right eye from homemade fireworks. Following initial assessment involving maxillofacial computed tomography (CT) and suturing at the Emergency Department, he was transferred to our department for further evaluation because of his poor sight 1 day later. On examination, a skin laceration beneath the right eyebrow was noted, but the superior orbit was not fully visible on the maxillofacial CT performed 1 day previously. Therefore, an orbital CT scan was carried out on the second day, which showed a hyperdense ring embedded in the superior border of the orbital wall; the ring was surgically removed. On postoperative day 7, a fundus examination revealed resolving vitreous hemorrhage, blunt traumatic retinal detachment, and a large retinal tear superior to the macula. The patient refused to take surgery for retinal detachment into consideration. Therefore, we opted for oral steroids and careful observation. After 2 months' observation, the large retinal tear had healed and white fibrous scar tissue had developed, and the retinal detachment superior to the macula had reattached itself spontaneously. The patient's vision had further improved to 20/200. During 1 year of follow-up, he remained clinically stable. To avoid missing the diagnosis, a complete history of the mechanism of injury and accurate imaging still prove most useful. Complete removal of the foreign body by the emergency physician is necessary because of the ocular toxicity of an iron-containing foreign body. As evidenced by the current case, oral steroids and observation for a period of several months is a management of choice for traumatic retinal detachment and retinal tear superior to the macula associated with homemade fireworks in children.

  15. Visibility in the Netherlands during New Year's fireworks: The role of soot and salty aerosol products

    The visibility on New Year's nights in the Netherlands is low during stagnant weather. This is due to the scattering and absorption of light by the aerosol-smoke from the fireworks. We made an assessment of the responsible aerosol-species. The investigation took place during the New Year's night of 2009. Measurements were made at a regional site in the centre of the country away from specific local sources. An Integrating Nephelometer measured the light-scattering by the inherent compounds after removal of water from the aerosol by drying the air. The actual light-scattering was determined in an open-air scatterometer; it was a factor of five higher than the ;dry; value. The difference in actual and ;dry; light-scattering can only be explained by water-uptake of the salty hygroscopic components of the aerosol. This hypothesis is substantiated by measurements of the composition of the aerosol. The size-dependent concentrations of the salty ionic species were determined on-line with a MARGA-;sizer;. These components were for a large part in particles in the size range that most effectively scatter light. The ;dry; light-scattering was exerted by the inorganic salt components and the sooty carbonaceous material alike. However, the salty products from the fireworks are hygroscopic and take up water at the high relative humidities occurring that night. This explains the fivefold larger light-scattering by the wet ambient aerosol as compared to that by the dry aerosol in the integrating nephelometer. The visibility, which is the inverse of the open-air scattering, is thus indirectly governed by the salty products of the fireworks due to their uptake of water. Under stagnant weather conditions during New Year's nights in the Netherlands both the aerosol concentrations and the relative humidity are high; this implies that the ionic species govern the low visibilities in general, be it via their uptake of water.

    Welch, Robin; Braseth, Alf Ove; Veland, Oeystein

    2004-01-01

    This paper presents the concept Information Rich Displays. The purpose of Information Rich Displays (IRDs) is to condensate prevailing information in process displays in such a way that each display format (picture) contains more relevant information for the user. Compared to traditional process control displays, this new concept allows the operator to attain key information at a glance and at the same time allows for improved monitoring of larger portions of the process. This again allows for reduced navigation between both process and trend displays and ease the cognitive demand on the operator. This concept has been created while working on designing display prototypes for the offshore petroleum production facilities of tomorrow. Offshore installations basically consist of wells, separation trains (where oil, gas and water are separated from each other), an oil tax measurement system (where oil quality is measured and the pressure increased to allow for export), gas compression (compression of gas for export) and utility systems (water treatment, chemical systems etc.). This means that an offshore control room operator has to deal with a complex process that comprises several functionally different systems. The need for a new approach to offshore display format design is in particular based on shortcomings in today's designs related to the keyhole effect, where the display format only reveals a fraction of the whole process. Furthermore, the upcoming introduction of larger off- and on-shore operation centres will increase the size and complexity of the operators' work domain. In the light of the increased demands on the operator, the proposed IRDs aim to counter the negative effects this may have on the workload. In this work we have attempted to classify the wide range of different roles an operator can have in different situations. The information content and amount being presented to the operator in a display should be viewed in context of the roles the

    Nowadays two display types are dominant in the display market: the bulky cathode ray tube (CRT) and liquid crystal displays (LCD). Both types use glass as substrate material. The LCD display is the dominant player for mobile applications, in for instance mobile phones and portable computers. In the development of displays and their applications a clear interest exists to replace the rigid rectangular display cells by free-shaped, curved or even roll-up cells. These types of applications require flexible displays.

  5. Influence of variable heat transfer coefficient of fireworks and crackers on thermal explosion critical ambient temperature and time to ignition

    2016-01-01

    Full Text Available To study the effect of variable heat transfer coefficient of fireworks and crackers on thermal explosion critical ambient temperature and time to ignition, considering the heat transfer coefficient as the power function of temperature, mathematical thermal explosion steady state and unsteady-state model of finite cylindrical fireworks and crackers with complex shell structures are established based on two-dimensional steady state thermal explosion theory. The influence of variable heat transfer coefficient on thermal explosion critical ambient temperature and time to ignition are analyzed. When heat transfer coefficient is changing with temperature and in the condition of natural convection heat transfer, critical ambient temperature lessen, thermal explosion time to ignition shorten. If ambient temperature is close to critical ambient temperature, the influence of variable heat transfer coefficient on time to ignition become large. For firework with inner barrel in example analysis, the critical ambient temperature of propellant is 463.88 K and the time to ignition is 4054.9s at 466 K, 0.26 K and 450.8s less than without considering the change of heat transfer coefficient respectively. The calculation results show that the influence of variable heat transfer coefficient on thermal explosion time to ignition is greater in this example. Therefore, the effect of variable heat transfer coefficient should be considered into thermal safety evaluation of fireworks to reduce potential safety hazard.

    Full Text Available Nowadays, wireless power transfer is ubiquitously used in wireless rechargeable sensor networks (WSNs. Currently, the energy limitation is a grave concern issue for WSNs. However, lifetime enhancement of sensor networks is a challenging task need to be resolved. For addressing this issue, a wireless charging vehicle is an emerging technology to expand the overall network efficiency. The present study focuses on the enhancement of overall network lifetime of the rechargeable wireless sensor network. To resolve the issues mentioned above, we propose swarm intelligence based hard clustering approach using fireworks algorithm with the adaptive transfer function (FWA-ATF. In this work, the virtual clustering method has been applied in the routing process which utilizes the firework optimization algorithm. Still now, an FWA-ATF algorithm yet not applied by any researcher for RWSN. Furthermore, the validation study of the proposed method using the artificial neural network (ANN backpropagation algorithm incorporated in the present study. Different algorithms are applied to evaluate the performance of proposed technique that gives the best results in this mechanism. Numerical results indicate that our method outperforms existing methods and yield performance up to 80% regarding energy consumption and vacation time of wireless charging vehicle.

    Two to three weeks after the explosion of a fireworks storage facility in a residential area (May 2000, Enschede, The Netherlands) we assessed the self-reported physical and mental health among those affected by the disaster. A questionnaire survey was conducted among 3792 residents, passers-by, and rescue workers, who were involved in and/or affected by the disaster and were > or =18 years of age. At least 30% of those affected by the disaster reported serious physical and mental health problems 2-3 weeks after the explosion. Compared with reference values in the general Dutch population, high scores were found for somatic symptoms, sleeping problems, and restrictions in daily functioning due to physical and mental problems, such as anxiety, depression, and feelings of insufficiency. The strength of these differences varied between groups, based on the level of involvement and the level of being affected. Results indicate that the fireworks disaster had a substantial impact on the health of those affected by the disaster. The health impact was most pronounced for residents and passers-by and also for rescue workers living in the affected area, but to a lesser degree. Physical and mental health problems were strongly associated with the shocking experiences during and shortly after the disaster.

The BB and firework episodes had only a minor influence on the water-soluble OC (organic carbon) to OC ratio. Based on separate investigations of episode and non-episode periods, it was found that: (i) sulfate correlated strongly with both relative humidity and nitrate during the typical winter period presumably indicating the importance of the aqueous-phase oxidation of sulfur dioxide by nitrogen dioxide, (ii) oxalate and WSOC during both winter and summer in Beijing were mainly due to secondary formation, and (iii) high humidity can significantly enhance the formation potential of WSOC in winter.

    The increased access to books afforded to blind people via e-publishing has given them long-sought independence for both recreational and educational reading. In most cases, blind readers access materials using speech output. For some content such as highly technical texts, music, and graphics, speech is not an appropriate access modality as it does not promote deep understanding. Therefore blind braille readers often prefer electronic braille displays. But, these are prohibitively expensive. The search is on, therefore, for a low-cost refreshable display that would go beyond current technologies and deliver graphical content as well as text. And many solutions have been proposed, some of which reduce costs by restricting the number of characters that can be displayed, even down to a single braille cell. In this paper, we demonstrate that restricting tactile cues during braille reading leads to poorer performance in a letter recognition task. In particular, we show that lack of sliding contact between the fingertip and the braille reading surface results in more errors and that the number of errors increases as a function of presentation speed. These findings suggest that single cell displays which do not incorporate sliding contact are likely to be less effective for braille reading.

  14. Nuclear image display controller

    International Nuclear Information System (INIS)

    Roth, D.A.

    1985-01-01

    In a nuclear imaging system the digitized x and y coordinates of gamma ray photon emission events address memory locations corresponding to the coordinates. The respective locations are incremented each time they are addressed so at the end of a selected time or event count period the locations contain digital values or raw data corresponding to the intensity of pixels comprising an image frame. The raw data for a frame is coupled to one input of an arithmetic logic unit (ALU) whose output is coupled to a display controller memory. The output of the controller memory is coupled to another ALU input with a feedback bus and is also coupled to a further signal processing circuit which includes means for converting processed data to analog video signals for television display. The ALU is selectively controlled to let raw image data pass through to the display controllor memory or alternately to add (or subtract) raw data for the last image frame developed to the raw data for preceding frames held in the display controller to thereby produce the visual effect on the television screen of an isotope flowing through anatomy

    The device of the present invention conducts information processing suitable for a man to solve a problem in a plant such as a nuclear power plant incorporating a great amount of information, where safety is required and provides information to an operator. Namely, theories and rules with respect to the flow and balanced state of materials and energy upon plant start-up, and a vapor cycle of operation fluids are symbolized and displayed on the display screen of the device. Then, the display of the plant information suitable to the information processing for a man to dissolve problems is provided. Accordingly, a mechanism for analyzing a purpose of the plant is made more definite, thereby enabling to prevent an erroneous judgement of an operator and occurrence of plant troubles. In addition, a simular effect can also be expected when the theories and rules with respect to the flow and the balanced state of materials and energy and thermohydrodynamic behavior of the operation fluids in a state of after-heat removing operation during shutdown of the plant are symbolized and displayed.

    Fueled by falling display hardware costs and rising demand, digital signage and pervasive displays are becoming ever more ubiquitous. Such systems have traditionally been used for advertising and information dissemination, with digital signage commonplace in shopping malls, airports and public spaces. While advertising and broadcasting announcements remain important applications, developments in sensing and interaction technologies are enabling entirely new classes of display applications that tailor content to the situation and audience of the display.

    Object: To provide a device capable of easily and quickly reading mutual mounting relations of control bodies such as control rods mounted on a nuclear reactor and positions to which the control bodies are driven. Structure: A scanning circuit is provided to scan positions of controllably mounted control bodies such as control rods. Values detected by scanning the positions are converted into character signals according to the values and converted into preranked color signals. The character signals and color signals are stored in a memory circuit by synchronous signals in synchronism with the scanning in the scanning circuit. Outputs of the memory circuit are displayed by a display unit such as a color Braun tube in accordance with the synchronous signals to provide color representations according to positions to which control bodies are driven in the same positional relation as the mounting of the control bodies.

    1989-01-01

    For any multichannel data acquisition system, a multichannel paper chart recorder undoubtedly forms an essential part of the system. When deployed on-line, it instantaneously provides, for visual inspection, hard copies of the signal waveforms on common time base at any desired sensitivity and time resolution. Within the country, only a small range of these strip chart recorder s is available, and under stringent specifications imported recorders are often procured. The cost of such recorders may range from 1 to 5 lakhs of rupees in foreign exchange. A system to provide on the oscilloscope a steady display of multichannel waveforms, refreshed from the digital data stored in the memory is developed. The merits and demerits of the display system are compared with that built around a conventional paper chart recorder. Various illustrations of multichannel seismic event data acquired at Gauribidanur seismic array station are also presented. (author). 2 figs

  19. Facial Displays Are Tools for Social Influence.

    Crivelli, Carlos; Fridlund, Alan J

    2018-05-01

    Based on modern theories of signal evolution and animal communication, the behavioral ecology view of facial displays (BECV) reconceives our 'facial expressions of emotion' as social tools that serve as lead signs to contingent action in social negotiation. BECV offers an externalist, functionalist view of facial displays that is not bound to Western conceptions about either expressions or emotions. It easily accommodates recent findings of diversity in facial displays, their public context-dependency, and the curious but common occurrence of solitary facial behavior. Finally, BECV restores continuity of human facial behavior research with modern functional accounts of non-human communication, and provides a non-mentalistic account of facial displays well-suited to new developments in artificial intelligence and social robotics.

    1984-01-01

    The improvement of contrast and visibility of LCD by two different means was undertaken. The two methods are: (1) development of fluorescent dyes to increase the visibility of fluorescent activated displays (FLAD); and (2) development of dichroic dyes to increase the contrast of displays. This work was done in close cooperation with the electronic industry, where the newly synthesized dyes were tested. The targets for the chemical synthesis were selected with the help of computer model calculations. A marketable range of dyes was developed. Since the interest of the electronic industries concerning FLAD was low, the investigations were stopped. Dichroic dyes, especially black mixtures with good light fastness, order parameter, and solubility in nematic phases were developed. The application of these dyes is restricted to indoor use because of an increase of viscosity below -10 C. Applications on a technical scale, e.g., for the automotive industry, will be possible if the displays work at temperatures down to -40 C. This problem requires a complex optimization of the dye/nematic phase system.

    Projectors based on polymer-eNCAPsulated liquid crystals can provide bright displays suitable for use in conference rooms with normal lighting. Contrast is generated by light scattering among the droplets, rather than by light absorption with crossed polarizers. We have demonstrated a full-color, compact projector showing 1200 ANSI lumens with 200 watts of lamp power - a light efficiency of 6 lumens/watt. This projector is based on low-voltage NCAP material, highly reflective CMOS die, and matched illumination and projection optics. We will review each of these areas and discuss the integrated system performance.

    2006-04-01

    Little is known about the effects of cumulative trauma and whether traumatized individuals are more vulnerable. In 2000, a fireworks disaster created the possibility to examine this issue among World War II survivors who were part of an ongoing longitudinal study. Between 1998 and 2000 posttraumatic stress increased in disaster exposed respondents as opposed to the control group. War-related reexperiencing and avoidance also increased. The strongest increase occurred in disaster-exposed respondents who had low levels of wartime stress and a slight decrease occurred in those who had high wartime exposure. This unique controlled observation suggests that disasters do increase the levels of posttraumatic stress, and that reactivation of previous traumatic events generally occurs. However, the vulnerability hypothesis was not supported.

    Romano, Eugenia; Elklit, Ask

    This study investigates which factors had the biggest impact on developing distress in rescue workers who were involved in a firework factory explosion. Four hundred sixty-five rescuers were assessed using items investigating demographic factors, organizational variables, social support, personality variables, and distress symptoms. Correlation and regression analyses were performed. Our final model provided 70 percent of the predictive model for post-traumatic stress disorder (PTSD) severity. Waiting time, lack of rest, problems at work, and perceived level of danger seemed to have the highest impact on protective factors. In addition to perceived life danger and personality, small organizational factors seem to play an important role in the prediction of PTSD. The importance of such factors needs further investigation in future research, contributing to a better organization in the field of disaster management.

    To study the type, severity, management and outcome of firework-related adnexal and ocular injuries during New Year's Eve festivities. A retrospective analysis of 123 injured patients (143 eyes) treated at the Rotterdam Eye Hospital between 2009 and 2013. All ages were included and analysed according to age, gender, active participant or bystander, laterality, location, dimension and severity of injury. Outcome parameter was the final best-corrected visual acuity. The mean age was 22 ± 13 years with 87% males and 53% bystanders. 52% were ≤18 years. There was a higher number of female than male bystanders (63% versus 51%, p = 0.30). 50% of the eyes sustained mild, 13% moderate and 37% severe trauma. Adults suffered more from severe injuries compared to children (42% versus 31%). The most frequent intervention was gunpowder removal (20%), followed by traumatic cataract surgery (12%) and amniotic membrane grafting (8%). 76% of patients were followed over 1 year. At the end of follow-up, 88 (61.5%) eyes had recovered fully, while 55 (38.5%) eyes suffered from persistent complications with reduced vision ≤0.8 in 30% of injured eyes. 15 patients (12%, 10 adults, five children) were considered legally blind (vision ≤0.1). Three (2%) eyes were subject to evisceration. Every year, around New Year's Eve 30-45 victims were referred to the Rotterdam Eye Hospital; 50% sustained moderate-to-severe trauma. In severe firework injuries, patients required multiple treatments that may not prevent permanent blindness and/or functional/cosmetic disfigurement. The majority was bystander and younger than 18 years. © 2018 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    In this review we will focus on recent progress in the field of two-dimensional (2D) and three-dimensional (3D) display technologies. We present the current display materials and their applications, including organic light-emitting diodes (OLEDs), flexible OLEDs quantum dot light emitting diodes (QLEDs), active-matrix organic light emitting diodes (AMOLEDs), electronic paper (E-paper), curved displays, stereoscopic 3D displays, volumetric 3D displays, light field 3D displays, and holographic 3D displays. Conventional 2D display devices, such as liquid crystal devices (LCDs) often result in ambiguity in high-dimensional data images because of lacking true depth information. This review thus provides a detailed description of 3D display technologies. (topical review)

  12. Icing Forecasting of High Voltage Transmission Line Using Weighted Least Square Support Vector Machine with Fireworks Algorithm for Feature Selection

    Directory of Open Access Journals (Sweden)

    Tiannan Ma

    2016-12-01

    Full Text Available Accurate forecasting of icing thickness has great significance for ensuring the security and stability of the power grid. In order to improve the forecasting accuracy, this paper proposes an icing forecasting system based on the fireworks algorithm and weighted least square support vector machine (W-LSSVM. The method of the fireworks algorithm is employed to select the proper input features with the purpose of eliminating redundant influence. In addition, the aim of the W-LSSVM model is to train and test the historical data-set with the selected features. The capability of this proposed icing forecasting model and framework is tested through simulation experiments using real-world icing data from the monitoring center of the key laboratory of anti-ice disaster, Hunan, South China. The results show that the proposed W-LSSVM-FA method has a higher prediction accuracy and it may be a promising alternative for icing thickness forecasting.

    2002-05-01

    A 3D head mounted display (HMD) system is useful for constructing a virtual space. The authors have researched the virtual-reality systems connected with computer networks for real-time remote control and developed a low-priced real-time 3D display for building these systems. We developed a 3D HMD system using monocular multi-view displays. The 3D displaying technique of this monocular multi-view display is based on the concept of the super multi-view proposed by Kajiki at TAO (Telecommunications Advancement Organization of Japan) in 1996. Our 3D HMD has two monocular multi-view displays (used as a visual display unit) in order to display a picture to the left eye and the right eye. The left and right images are a pair of stereoscopic images for the left and right eyes, then stereoscopic 3D images are observed.

    1996-03-01

    Large screen information displays are defined as dynamic electronic displays that can be viewed by more than one person and are at least 2-feet wide. These large area displays for public viewing provide convenience, entertainment, security, and efficiency to the viewers. There are numerous uses for large screen information displays including those in advertising, transportation, traffic control, conference room presentations, computer aided design, banking, and military command/control. A noticeable characteristic of the large screen display market is the interchangeability of display types. For any given application, the user can usually choose from at least three alternative technologies, and sometimes from many more. Some display types have features that make them suitable for specific applications due to temperature, brightness, power consumption, or other such characteristic. The overall worldwide unit consumption of large screen information displays of all types and for all applications (excluding consumer TV) will increase from 401,109 units in 1995 to 655,797 units in 2002. On a unit consumption basis, applications in business and education represent the largest share of unit consumption over this time period; in 1995, this application represented 69.7% of the total. The market (value of shipments) will grow from DOL3.1 billion in 1995 to DOL3.9 billion in 2002. The market will be dominated by front LCD projectors and LCD overhead projector plates.

    2014-01-01

    The LHCb Event Display was made for educational purposes at the European Organization for Nuclear Research, CERN in Geneva, Switzerland. The project was implemented as a stand-alone application using C++ and ROOT, a framework developed by CERN for data analysis. This paper outlines the development and architecture of the application in detail, as well as the motivation for the development and the goals of the exercise. The application focuses on the visualization of events recorded by the LHCb detector, where an event represents a set of charged particle tracks in one proton-proton collision. Every particle track is coloured by its type and can be selected to see its essential information such as mass and momentum. The application allows students to save this information and calculate the invariant mass for any pair of particles. Furthermore, the students can use additional calculating tools in the application and build up a histogram of these invariant masses. The goal for the students is to find a $D^0$ par...

  18. Colorimetry for CRT displays.

    Science.gov (United States)

    Golz, Jürgen; MacLeod, Donald I A

    2003-05-01

    We analyze the sources of error in specifying color in CRT displays. These include errors inherent in the use of the color matching functions of the CIE 1931 standard observer when only colorimetric, not radiometric, calibrations are available. We provide transformation coefficients that prove to correct the deficiencies of this observer very well. We consider four different candidate sets of cone sensitivities. Some of these differ substantially; variation among candidate cone sensitivities exceeds the variation among phosphors. Finally, the effects of the recognized forms of observer variation on the visual responses (cone excitations or cone contrasts) generated by CRT stimuli are investigated and quantitatively specified. Cone pigment polymorphism gives rise to variation of a few per cent in relative excitation by the different phosphors--a variation larger than the errors ensuing from the adoption of the CIE standard observer, though smaller than the differences between some candidate cone sensitivities. Macular pigmentation has a larger influence, affecting mainly responses to the blue phosphor. The estimated combined effect of all sources of observer variation is comparable in magnitude with the largest differences between competing cone sensitivity estimates but is not enough to disrupt very seriously the relation between the L and M cone weights and the isoluminance settings of individual observers. It is also comparable with typical instrumental colorimetric errors, but we discuss these only briefly.

    Jefferson Lab's Web Extensible Display Manager (WEDM) allows staff to access EDM control system screens from a web browser in remote offices and from mobile devices. Native browser technologies are leveraged to avoid installing and managing software on remote clients such as browser plugins, tunnel applications, or an EDM environment. Since standard network ports are used firewall exceptions are minimized. To avoid security concerns from remote users modifying a control system, WEDM exposes read-only access and basic web authentication can be used to further restrict access. Updates of monitored EPICS channels are delivered via a Web Socket using a web gateway. The software translates EDM description files (denoted with the edl suffix) to HTML with Scalable Vector Graphics (SVG) following the EDM's edl file vector drawing rules to create faithful screen renderings. The WEDM server parses edl files and creates the HTML equivalent in real-time allowing existing screens to work without modification. Alternatively, the familiar drag and drop EDM screen creation tool can be used to create optimized screens sized specifically for smart phones and then rendered by WEDM.

    1988-01-01

    Main trends in development of display systems used as the means for image displaying in NPP control systems are considered. It is shown that colour display devices appear to be the most universal means for concentrated data presentation. Along with digital means the display systems provide for high-speed response, sufficient for operative control of executive mechanisms. A conclusion is drawn that further development of display systems will move towards creation of large colour fields (on reflection base or with multicolour gas-discharge elements)

    The first poster session by students working on the LHC experiments, organised by the LPCC, was a great success. Showcasing the talents of over a hundred young physicists from all over the world, it was an opportunity for everyone at CERN to check out the wide range of research work being done by the new generation of physicists at CERN.   At 5.30 p.m. on Wednesday 23 March, the first poster session by CERN students took place in Restaurant No.1, where no fewer than 87 posters went on public display. The students were split into 8 groups according to their research field* and all were on hand to answer the questions of an inquisitive audience. TH Department's Michelangelo Mangano, who is head of the LHC Physics Centre at CERN (LPCC) and is responsible for the initiative, confirms that nothing was left to chance, even the choice of date: "We wanted to make the most of the general enthusiasm around the winter conferences and the meeting of the LHC Experiments Committee to present the stud...

  2. Augmenting digital displays with computation

    Science.gov (United States)

    Liu, Jing

    As we inevitably step deeper and deeper into a world connected via the Internet, more and more information will be exchanged digitally. Displays are the interface between digital information and each individual. Naturally, one fundamental goal of displays is to reproduce information as realistically as possible since humans still care a lot about what happens in the real world. Human eyes are the receiving end of such information exchange; therefore it is impossible to study displays without studying the human visual system. In fact, the design of displays is rather closely coupled with what human eyes are capable of perceiving. For example, we are less interested in building displays that emit light in the invisible spectrum. This dissertation explores how we can augment displays with computation, which takes both display hardware and the human visual system into consideration. Four novel projects on display technologies are included in this dissertation: First, we propose a software-based approach to driving multiview autostereoscopic displays. Our display algorithm can dynamically assign views to hardware display zones based on multiple observers' current head positions, substantially reducing crosstalk and stereo inversion. Second, we present a dense projector array that creates a seamless 3D viewing experience for multiple viewers. We smoothly interpolate the set of viewer heights and distances on a per-vertex basis across the arrays field of view, reducing image distortion, crosstalk, and artifacts from tracking errors. Third, we propose a method for high dynamic range display calibration that takes into account the variation of the chrominance error over luminance. We propose a data structure for enabling efficient representation and querying of the calibration function, which also allows user-guided balancing between memory consumption and the amount of computation. Fourth, we present user studies that demonstrate that the ˜ 60 Hz critical flicker fusion

    With quickly advance of the computer, microelectronics and photonics technologies, LED display panel becomes a new electronic advertising media. It can be used to show any information whatever characters or graphics. Most LED display panels are built of many Light-Emitting Diodes arranged in a matrix form. The display has many advantages such as low power, low cost, long life and high definition. Because the display panel is asked to show rich color, the LED display panel's driving system becomes very complex. The design methodology of LED display panel's driver becomes more and more important to meet the market requirements. Cost is always the most important issue in public market domain. In this paper, we report a design methodology of LED display panel's driver based on the microprocessor control unit (MCU) system and LED display controller IC, HT1632C, to control three colors, RGB, color LED display panel and the modular panel size is 24*16 in matrix form. The HT1632C is a memory mapping LED display controller, it can be used on many applications, such as digital clock, thermometer, counter, voltmeter or other instrumentation readouts. Three pieces of HT1632C are used to drive a 24*16 RGB LED display panel, in our design case. Each HT163C chip is used to control one of the R, G and B color. As the drive mode is driven in DC mode, the RGB display panel can create and totally of seven colors under the control of MCU. The MCU generates the control signal to drive HT1632C. In this study, the software design methodology is adopted with dynamic display principle. When the scan frequency is 60Hz, LED display panel will get the clear picture and be able to display seven colors.

    Recognizing the value of autostereoscopy for 3D displays in public contexts, we pursue the goal of large-scale, high-resolution, immersive virtual reality using lenticular displays. Our contributions include the scalable tiling of lenticular displays to large fields of view and the use of GPU image interleaving and application optimization for real-time performance. In this context, we examine several ways to improve group-viewing by combining user tracking with multi-view displays. Copyright © 2010 by the Association for Computing Machinery, Inc.

    A 10 inch laser illuminated flat panel Planar Optic Display (POD) screen has been constructed and tested. This POD screen technology is an entirely new concept in display technology. Although the initial display is flat and made of glass, this technology lends itself to applications where a plastic display might be wrapped around the viewer. The display screen is comprised of hundreds of planar optical waveguides where each glass waveguide represents a vertical line of resolution. A black cladding layer, having a lower index of refraction, is placed between each waveguide layer. Since the cladding makes the screen surface black, the contrast is high. The prototype display is 9 inches wide by 5 inches high and approximately I inch thick. A 3 milliwatt HeNe laser is used as the illumination source and a vector scanning technique is employed.

    With the virtue of rapid progress in optics, sensors, and computer science, we are witnessing that commercial products or prototypes for augmented reality (AR) are penetrating into the consumer markets. AR is spotlighted as expected to provide much more immersive and realistic experience than ordinary displays. However, there are several barriers to be overcome for successful commercialization of AR. Here, we explore challenging and important topics for AR such as image combiners, enhancement of display performance, and focus cue reproduction. Image combiners are essential to integrate virtual images with real-world. Display performance (e.g. field of view and resolution) is important for more immersive experience and focus cue reproduction may mitigate visual fatigue caused by vergence-accommodation conflict. We also demonstrate emerging technologies to overcome these issues: index-matched anisotropic crystal lens (IMACL), retinal projection displays, and 3D display with focus cues. For image combiners, a novel optical element called IMACL provides relatively wide field of view. Retinal projection displays may enhance field of view and resolution of AR displays. Focus cues could be reconstructed via multi-layer displays and holographic displays. Experimental results of our prototypes are explained.

  10. Parametric optimization of ultrasonic machining process using gravitational search and fireworks algorithms

    Full Text Available Ultrasonic machining (USM is a mechanical material removal process used to erode holes and cavities in hard or brittle workpieces by using shaped tools, high-frequency mechanical motion and an abrasive slurry. Unlike other non-traditional machining processes, such as laser beam and electrical discharge machining, USM process does not thermally damage the workpiece or introduce significant levels of residual stress, which is important for survival of materials in service. For having enhanced machining performance and better machined job characteristics, it is often required to determine the optimal control parameter settings of an USM process. The earlier mathematical approaches for parametric optimization of USM processes have mostly yielded near optimal or sub-optimal solutions. In this paper, two almost unexplored non-conventional optimization techniques, i.e. gravitational search algorithm (GSA and fireworks algorithm (FWA are applied for parametric optimization of USM processes. The optimization performance of these two algorithms is compared with that of other popular population-based algorithms, and the effects of their algorithm parameters on the derived optimal solutions and computational speed are also investigated. It is observed that FWA provides the best optimal results for the considered USM processes.

    Seismic experiments were conducted on Showa-Shinzan, a parasitic lava dome of volcano Usu, Hokkaido, which was formed during 1943 1945 activity. Since we found that firework shots fired on the ground can effectively produce seismic waves, we placed many seismometers on and around the dome during the summer festivals in 1984 and 1985. The internal structure had been previously studied using a prospecting technique employing dynamite blasts in 1954. The measured interval velocity across the dome in 1984 ranges 1.8 2.2 km/s drastically low compared to the results (3.0 4.0 km/s) in 1954; in addition, the velocity is 0.3 0.5 km/s higher than that in the surrounding area. The variation of the observed first arrival amplitudes can be explained by geometrical spreading in the high velocity lava dome. These observations show a marked change in the internal physical state of the dome corresponding to a drop in the measured highest temperature at fumaroles on the dome from 800°C in 1947 to 310°C in 1986.

    Raiyaku, as a type of raw material for explosive, are very dangerous , has high explosive power but there are difficulties in dretermining blast characteristics in terms of TNT equivalence. This study was made using raiyaku, firework mixture of 70 wt % potassium perchlorate, 15 wt % aluminium powder and 15 wt % titanium Powder. Blast characteristics of the raiyaku were studied exploding 1 Kg of the mixture in the sky and 30 Kg and 50 Kg in the surface at range in scaled distance from 1 to 15 m/kg{sup (1/3)} using piezoelectric gauges and lead-Plate blastmeters. As blast characteristics, equivalence was determined on the basis of measured Peak overpressures. Scaled distances when ploted against TNT equivalence, it has been cleared that TNT equivalence was 52.2 % on average with standard error of 8.4 %. Further it was clear that with the increase of equivalent distance TNT equivalence has increased from about 40 % to 60 %. 10 refs., 4 figs., 3 tabs.

    When the psychosocial-care scheme for victims of the firework explosion in Enschede, the Netherlands (2000) was set up, lessons learned from the Bijlmer airline disaster (Amsterdam 1992) were put into practice. The aftermath of this incident showed that psychological and physical health problems can still occur many years later. The main failure of the aftercare of the Bijlmer disaster lay in the coordination of aid and the monitoring of health problems. In Enschede steps were taken to redress these problems. An information and advice centre (IAC) was set up to monitor the well-being of the victims, and to provide them with information and, where necessary, assistance. It is responsible for limiting the effects of the disaster. A total of 13,000 people have consulted the IAC. A residents' association was formed. This gave the victims a common voice during the process of attempting to restore normality in their lives. A specialized mental health-care unit was founded to treat disaster-related disorders using evidence-based treatments. So far approximately 1,300 people have consulted this body. A longitudinal study has been set up to map the consequences of the disaster and to advise aid organizations. This will also give information on the extent to which these methods have been able to limit the long-term consequences.

    2003-05-07

    WIRED (World-Wide Web Interactive Remote Event Display) is a framework, written in the Java{trademark} language, for building High Energy Physics event displays. An event display based on the WIRED framework enables users of a HEP collaboration to visualize and analyze events remotely using ordinary WWW browsers, on any type of machine. In addition, event displays using WIRED may provide the general public with access to the research of high energy physics. The recent introduction of the object-oriented Java{trademark} language enables the transfer of machine independent code across the Internet, to be safely executed by a Java enhanced WWW browser. We have employed this technology to create a remote event display in WWW. The combined Java-WWW technology hence assures a world wide availability of such an event display, an always up-to-date program and a platform independent implementation, which is easy to use and to install.

    Fireworks are commonly used in local and national celebrations. The aim of this study is to explore the extent, nature and hospital costs of injuries related to the Persian Wednesday Eve festival in Iran. Data for injuries caused by fireworks during the 2009 Persian Wednesday Eve festival were collected from the national Ministry of Health database. Injuries were divided into nine groups and the average and total hospital costs were estimated for each group. The cost of care for patients with burns was estimated by reviewing a sample of 100 patients randomly selected from a large burn center in Tehran. Other costs were estimated by conducting semi structured interviews with expert managers at two large government hospitals. 1817 people were injured by fireworks during the 2009 Wednesday Eve festival. The most frequently injured sites were the hand (43.3%), eye (24.5%) and face (13.2%), and the most common types of injury were burns (39.9%), contusions/abrasions (24.6%) and lacerations (12.7%). The mean length of hospital stay was 8.15 days for patients with burns, 10.7 days for those with amputations, and 3 days for those with other types of injury. The total hospital cost of injuries was US$ 284 000 and the average cost per injury was US$ 156. The total hospital cost of patients with amputations was US$ 48 598. Most of the costs were related to burns (56.6%) followed by amputations (12.2%). Injuries related to the Persian Wednesday Eve festival are common and lead to extensive morbidity and medical costs. © 2013 KUMS, All rights reserved.

    Objective The aim of this study was to determine control/display stereotypes for children of a range of ages and development of these stereotypes with age. Background Little is known about control/display stereotypes for children of different ages and the way in which these stereotypes develop with age. This study is part of a program to determine the need to design differentially for these age groups. Method We tested four groups of children with various tasks (age groups 5 to 7, 8 to 10, 11 to 13, 14 to 16), with about 30 in each group. Examples of common tasks were opening a bottle, turning on taps, and allocating numbers to keypads. More complex tasks involved rotating a control to move a display in a requested direction. Results Tasks with which different age groups were familiar showed no effect of age group. Different control/display arrangements generally showed an increase in stereotype strength with age, with dependence on the form of the control/display arrangement. Two-dimensional arrangements, with the control on the same plane as the display, had higher stereotype strength than three-dimensional arrangements for all age groups, suggesting an effect of familiarity with controls and displays with increasing age. Conclusion Children's control/display stereotypes do not differ greatly from those of adults, and hence, design for children older than 5 years of age, for control/display stereotypes, can be the same as that for adult populations. Application When designing devices for children, the relationship between controls and displays can be as for adult populations, for which there are considerable experimental data.

    A computer program is currently under development to model in 3D - one dimension of which is wavelength - all the known and major speculated sources of ultraviolet (900 A - 3100 A ) radiation over the celestial sphere. The software is being written in Fortran 77 and IDL and currently operates under IRIX (the operating system of the Silicon Graphics Iris Machine); all output models are in FITS format. Models along with display software will become available to the astronomical community. The Ultraviolet Sky Model currently includes the Zodiacal Light, Point Sources of Emission, and the Diffuse Galactic Light. The Ultraviolet Sky Model is currently displayed using SkyView: a package under development at NASA/ GSFC, which allows users to retrieve and display publically available all-sky astronomical survey data (covering many wavebands) over the Internet. We present a demonstration of the SkyView display of the Ultraviolet Model. The modelling is a five year development project: the work illustrated here represents product output at the end of year one. Future work includes enhancements to the current models and incorporation of the following models: Galactic Molecular Hydrogen Fluorescence; Galactic Highly Ionized Atomic Line Emission; Integrated Extragalactic Light; and speculated sources in the intergalactic medium such as Ionized Plasma and radiation from Non-Baryonic Particle Decay. We also present a poster which summarizes the components of the Ultraviolet Sky Model and outlines a further package that will be used to display the Ultraviolet Model. This work is supported by United States Air Force Contract F19628-93-K-0004. Dr J. Daniels is supported with a post-doctoral Fellowship from the Leverhulme Foundation, London, United Kingdom.

    2015-01-01

    Two experiments are reported that were designed to investigate control/display arrangements having high stereotype strengths when using circular displays. Eight display locations relative to the operator and control were tested with rotational and translational controls situated on different planes according to the Frame of Reference Transformation Tool (FORT) model of Wickens et al. (2010). (Left. No, Right! Development of the Frame of Reference Transformation Tool (FORT), Proceedings of the Human Factors and Ergonomics Society 54th Annual Meeting, 54: 1022-1026). In many cases, there was little effect of display locations, indicating the importance of the Worringham and Beringer (1998. Directional stimulus-response compatibility: a test of three alternative principles. Ergonomics, 41(6), 864-880) Visual Field principle and an extension of this principle for rotary controls (Hoffmann and Chan (2013). The Worringham and Beringer 'visual field' principle for rotary controls. Ergonomics, 56(10), 1620-1624). The initial indicator position (12, 3, 6 and 9 o'clock) had a major effect on control/display stereotype strength for many of the six controls tested. Best display/control arrangements are listed for each of the different control types (rotational and translational) and for the planes on which they are mounted. Data have application where a circular display is used due to limited display panel space and applies to space-craft, robotics operators, hospital equipment and home appliances. Practitioner Summary: Circular displays are often used when there is limited space available on a control panel. Display/control arrangements having high stereotype strength are listed for four initial indicator positions. These arrangements are best for design purposes.

    At the beginning of this century, lighting technology has been shifted from discharge lamps, fluorescent lamps and electric bulbs to solid-state lighting. Current solid-state lighting is based on the light emitting diodes (LED) technology, but the laser lighting technology is developing rapidly, such as, laser cinema projectors, laser TVs, laser head-up displays, laser head mounted displays, and laser headlamps for motor vehicles. One of the main issues of laser displays is the reduction of speckle noise1). For the monochromatic laser light, speckle is random interference pattern on the image plane (retina for human observer). For laser displays, RGB (red-green-blue) lasers form speckle patterns independently, which results in random distribution of chromaticity, called color speckle2).

    Jones, Philip J.; Tomita, Akira; Wartenberg, Mark

    1991-08-01

    Prototypes of projection displays based on dispersions of liquid crystal in polymer matrices are beginning to appear. The principle of operation depends on electrically switchable light scattering. They are potentially much brighter than current cathode ray tube (CRT) or twisted nematic liquid crystal (TN LC) cell based displays. Comparisons of efficacy and efficiency show this. The contrast and brightness of such displays depend on a combination of the f- number of the projection system and the scattering characteristics of the light valve. Simplified equations can be derived to show these effects. The degree of scattering of current NCAP formulations is sufficient to produce good contrast projection displays, at convenient voltages, that are around three times brighter than TN LC projectors because of the lack of polarizers in the former.

    finite quasimomentum. We measured the growth of these domains over time and the correlation functions describing their spatial distribution by directly reconstructing the quasimomentum distribution. We observed the expected scaling laws across more than an order of magnitude in the crossing rate, aside from which the observed critical dynamics were indeed independent of the crossing rate. These experiments provide strong support for the universal scaling symmetry of space and time and the extension of the Kibble-Zurek mechanism to quantum phase transitions. We also present the first observation of Bose Fireworks: the sudden emission of many bright, narrow jets of atoms from condensates with oscillating interaction strength. Even though the underlying inelastic s-wave collisions induced by oscillating interactions are isotropic, the collective nature of collisions in the condensate causes the outgoing bosonic atoms to bunch into narrow jets in the horizontal plane. This bunching results from runaway stimulated collisions, which we find can only occur above a threshold oscillation amplitude. The observed atom number in the jets suggests that they are seeded by quantum fluctuations. Moreover, in azimuthal correlation functions we observe forward correlations consistent with theory, which saturate the limit from the uncertainty principle. We also observe partial correlation between counterpropagating jets. Bose Fireworks provide a well-controlled platform for understanding the diverse class of systems in which a coherent source rapidly emits pairs of counterpropagating bosons.

    Aerosol particles were characterized by an Aerodyne aerosol chemical speciation monitor along with various collocated instruments in Beijing, China, to investigate the role of fireworks (FW) and secondary aerosol in particulate pollution during the Chinese Spring Festival of 2013. Three FW events, exerting significant and short-term impacts on fine particles (PM2.5), were observed on the days of Lunar New Year, Lunar Fifth Day, and Lantern Festival. The FW were shown to have a large impact on non-refractory potassium, chloride, sulfate, and organics in submicron aerosol (PM1), of which FW organics appeared to be emitted mainly in secondary, with its mass spectrum resembling that of secondary organic aerosol (SOA). Pollution events (PEs) and clean periods (CPs) alternated routinely throughout the study. Secondary particulate matter (SPM = SOA + sulfate + nitrate + ammonium) dominated the total PM1 mass on average, accounting for 63-82% during nine PEs in this study. The elevated contributions of secondary species during PEs resulted in a higher mass extinction efficiency of PM1 (6.4 m2 g-1) than during CPs (4.4 m2 g-1). The Chinese Spring Festival also provides a unique opportunity to study the impact of reduced anthropogenic emissions on aerosol chemistry in the city. Primary species showed ubiquitous reductions during the holiday period with the largest reduction being in cooking organic aerosol (OA; 69%), in nitrogen monoxide (54%), and in coal combustion OA (28%). Secondary sulfate, however, remained only slightly changed, and the SOA and the total PM2.5 even slightly increased. Our results have significant implications for controlling local primary source emissions during PEs, e.g., cooking and traffic activities. Controlling these factors might have a limited effect on improving air quality in the megacity of Beijing, due to the dominance of SPM from regional transport in aerosol particle composition.

    The firework algorithm (FWA) is a novel swarm intelligence-based method recently proposed for the optimization of multi-parameter, nonlinear functions. Numerical waveform inversion experiments using a synthetic model show that the FWA performs well in both solution quality and efficiency. We apply the FWA in this study to crustal velocity structure inversion using regional seismic waveform data of central Gansu on the northeastern margin of the Qinghai-Tibet plateau. Seismograms recorded from the moment magnitude ( M W) 5.4 Minxian earthquake enable obtaining an average crustal velocity model for this region. We initially carried out a series of FWA robustness tests in regional waveform inversion at the same earthquake and station positions across the study region, inverting two velocity structure models, with and without a low-velocity crustal layer; the accuracy of our average inversion results and their standard deviations reveal the advantages of the FWA for the inversion of regional seismic waveforms. We applied the FWA across our study area using three component waveform data recorded by nine broadband permanent seismic stations with epicentral distances ranging between 146 and 437 km. These inversion results show that the average thickness of the crust in this region is 46.75 km, while thicknesses of the sedimentary layer, and the upper, middle, and lower crust are 3.15, 15.69, 13.08, and 14.83 km, respectively. Results also show that the P-wave velocities of these layers and the upper mantle are 4.47, 6.07, 6.12, 6.87, and 8.18 km/s, respectively.

  16. On-line data display

    A data display system for embedded realtime systems has been developed for use as an operator's user interface and debugging tool. The motivation for development of the On-Line Data Display (ODD) have come from several sources. In particular the design reflects the needs of researchers developing an experimental mobile robot within our laboratory. A proliferation of specialized user interfaces revealed a need for a flexible communications and graphical data display system. At the same time the system had to be readily extensible for arbitrary graphical display formats which would be required for data visualization needs of the researchers. The system defines a communication protocol transmitting 'datagrams' between tasks executing on the realtime system and virtual devices displaying the data in a meaningful way on a graphical workstation. The communication protocol multiplexes logical channels on a single data stream. The current implementation consists of a server for the Harmony realtime operating system and an application written for the Macintosh computer. Flexibility requirements resulted in a highly modular server design, and a layered modular object- oriented design for the Macintosh part of the system. Users assign data types to specific channels at run time. Then devices are instantiated by the user and connected to channels to receive datagrams. The current suite of device types do not provide enough functionality for most users' specialized needs. Instead the system design allows the creation of new device types with modest programming effort. The protocol, design and use of the system are discussed.

  20. IMDISP - INTERACTIVE IMAGE DISPLAY PROGRAM

    Martin, M. D.

    1994-01-01

    The Interactive Image Display Program (IMDISP) is an interactive image display utility for the IBM Personal Computer (PC, XT and AT) and compatibles. Until recently, efforts to utilize small computer systems for display and analysis of scientific data have been hampered by the lack of sufficient data storage capacity to accomodate large image arrays. Most planetary images, for example, require nearly a megabyte of storage. The recent development of the "CDROM" (Compact Disk Read-Only Memory) storage technology makes possible the storage of up to 680 megabytes of data on a single 4.72-inch disk. IMDISP was developed for use with the CDROM storage system which is currently being evaluated by the Planetary Data System. The latest disks to be produced by the Planetary Data System are a set of three disks containing all of the images of Uranus acquired by the Voyager spacecraft. The images are in both compressed and uncompressed format. IMDISP can read the uncompressed images directly, but special software is provided to decompress the compressed images, which can not be processed directly. IMDISP can also display images stored on floppy or hard disks. A digital image is a picture converted to numerical form so that it can be stored and used in a computer. The image is divided into a matrix of small regions called picture elements, or pixels. The rows and columns of pixels are called "lines" and "samples", respectively. Each pixel has a numerical value, or DN (data number) value, quantifying the darkness or brightness of the image at that spot. In total, each pixel has an address (line number, sample number) and a DN value, which is all that the computer needs for processing. DISPLAY commands allow the IMDISP user to display all or part of an image at various positions on the display screen. The user may also zoom in and out from a point on the image defined by the cursor, and may pan around the image. To enable more or all of the original image to be displayed on the

    A model is described which predicts the allocation of attention to the features of a radar display. It uses the growth of uncertainty and the probability of near collision to call the eye to a feature of the display. The main source of uncertainty is forgetting following a fixation, which is modelled as a two dimensional diffusion process. The model was used to predict information overload in intercept controllers, and preliminary validation obtained by recording eye movements of intercept controllers in simulated and live (practice) interception.

    1997-01-01

    The Single Event Display (SED) is a routine that is designed to provide information graphically about a triggered event within the Crystal Ball. The SED is written entirely in FORTRAN and uses the CERN-based HICZ graphing package. The primary display shows the amount of energy deposited in each of the NaI crystals on a Mercator-like projection of the crystals. Ten different shades and colors correspond to varying amounts of energy deposited within a crystal. Information about energy clusters is displayed on the crystal map by outlining in red the thirteen (or twelve) crystals contained within a cluster and assigning each cluster a number. Additional information about energy clusters is provided in a series of boxes containing useful data about the energy distribution among the crystals within the cluster. Other information shown on the event display include the event trigger type and data about π o 's and η's formed from pairs of clusters as found by the analyzer. A description of the major features is given, along with some information on how to install the SED into the analyzer

    1994-01-01

    The goal of this research was to help us understand the display requirements for a synthetic vision system for the High Speed Civil Transport (HSCT). Four experiments were conducted to examine the effects of different levels of perceptual cue complexity in displays used by pilots in a flare and landing task. Increased levels of texture mapping of terrain and runway produced mixed results, including harder but shorter landings and a lower flare initiation altitude. Under higher workload conditions, increased texture resulted in an improvement in performance. An increase in familiar size cues did not result in improved performance. Only a small difference was found between displays using two patterns of high resolution texture mapping. The effects of increased perceptual cue complexity on performance was not as strong as would be predicted from the pilot's subjective reports or from related literature. A description of the role of a synthetic vision system in the High Speed Civil Transport is provide along with a literature review covering applied research related to perceptual cue usage in aircraft displays.

    2003-04-01

    The Solar Active Region Display System (SARDS) is a client-server application that automatically collects a wide range of solar data and displays it in a format easy for users to assimilate and interpret. Users can rapidly identify active regions of interest or concern from color-coded indicators that visually summarize each region's size, magnetic configuration, recent growth history, and recent flare and CME production. The active region information can be overlaid onto solar maps, multiple solar images, and solar difference images in orthographic, Mercator or cylindrical equidistant projections. Near real-time graphs display the GOES soft and hard x-ray flux, flare events, and daily F10.7 value as a function of time; color-coded indicators show current trends in soft x-ray flux, flare temperature, daily F10.7 flux, and x-ray flare occurrence. Through a separate window up to 4 real-time or static graphs can simultaneously display values of KP, AP, daily F10.7 flux, GOES soft and hard x-ray flux, GOES >10 and >100 MeV proton flux, and Thule neutron monitor count rate. Climatologic displays use color-valued cells to show F10.7 and AP values as a function of Carrington/Bartel's rotation sequences - this format allows users to detect recurrent patterns in solar and geomagnetic activity as well as variations in activity levels over multiple solar cycles. Users can customize many of the display and graph features; all displays can be printed or copied to the system's clipboard for "pasting" into other applications. The system obtains and stores space weather data and images from sources such as the NOAA Space Environment Center, NOAA National Geophysical Data Center, the joint ESA/NASA SOHO spacecraft, and the Kitt Peak National Solar Observatory, and can be extended to include other data series and image sources. Data and images retrieved from the system's database are converted to XML and transported from a central server using HTTP and SOAP protocols, allowing

    Science.gov (United States)

    Brown, Michael A.

    2010-01-01

    The current Johnson Space Center (JSC) Mission Control Center (MCC) Video Transport System (VTS) provides flight controllers and management the ability to meld raw video from various sources with telemetry to improve situational awareness. However, maintaining a separate infrastructure for video delivery and integration of video content with data adds significant complexity and cost to the system. When considering alternative architectures for a VTS, the current system's ability to share specific computer displays in their entirety to other locations, such as large projector systems, flight control rooms, and back supporting rooms throughout the facilities and centers must be incorporated into any new architecture. Internet Protocol (IP)-based systems also support video delivery and integration. IP-based systems generally have an advantage in terms of cost and maintainability. Although IP-based systems are versatile, the task of sharing a computer display from one workstation to another can be time consuming for an end-user and inconvenient to administer at a system level. The objective of this paper is to present a prototype display sharing enterprise solution. Display sharing is a system which delivers image sharing across the LAN while simultaneously managing bandwidth, supporting encryption, enabling recovery and resynchronization following a loss of signal, and, minimizing latency. Additional critical elements will include image scaling support, multi -sharing, ease of initial integration and configuration, integration with desktop window managers, collaboration tools, host and recipient controls. This goal of this paper is to summarize the various elements of an IP-based display sharing system that can be used in today's control center environment.

    2014-02-01

    While virtual reality and digital games share many core technologies, the programming environments, toolkits, and workflows for developing games and VR environments are often distinct. VR toolkits designed for applications in visualization and simulation often have a different feature set or design philosophy than game engines, while popular game engines often lack support for VR hardware. Extending a game engine to support systems such as the CAVE gives developers a unified development environment and the ability to easily port projects, but involves challenges beyond just adding stereo 3D visuals. In this paper we outline the issues involved in adapting a game engine for use with an immersive display system including stereoscopy, tracking, and clustering, and present example implementation details using Unity3D. We discuss application development and workflow approaches including camera management, rendering synchronization, GUI design, and issues specific to Unity3D, and present examples of projects created for a multi-wall, clustered, stereoscopic display.

    The long-range transport (LRT) of pollutants between countries in Northeast Asia is a serious issue. However, reliable quantification of LRT pollutants has not been performed due to a lack of clear evidence of the transport between countries. Hourly chemical composition of PM2.5 (particulate matter with a diameter of ≤2.5 μm) was measured continuously at a suburban site in Daejeon, Korea during the Lunar New Year festival period to investigate the influence of firework/firecracker emissions from China over areas downwind subject to LRT. Elevated PM10 (particulate matter with a diameter of ≤10 μm) and PM2.5 mass concentrations were observed over the Korean Peninsula during the third day of the Lunar New Year festival (30 January 2017) when air masses originated from the northern part of China. Water-soluble potassium (K+), an indicator of both firework/firecracker and biomass burning, increased significantly during the third day of the Lunar New Year festival with an episode to non-episode ratio of 7.5, whereas no increase in levoglucosan, an indicator of biomass burning, was observed. Because firework/firecracker activities do not typically occur over the Korean Peninsula during the Lunar New Year festival, elevated K+ indicates that haze plumes mixed with firework/firecracker emissions in China impacted the Korean Peninsula through the LRT. This study finds, for the first time, clear evidence of the LRT of pollutants between source and receptor countries in Northeast Asia under Asian continental outflow.
