Abstract:

Submarines are considered extremely strategic for any naval army due to their stealth capability. Periscopes are crucial sensors for these vessels, and emerging to the surface or periscope depth is required to identify visual contacts through this device. This maneuver has many procedures and usually has to be fast and agile to avoid exposure. This paper presents and implements a novel architecture for real submarine periscopes developed for future Brazilian naval fleet operations. Our system consists of a probe that is connected to the craft and carries a 360 camera. We project and take the images inside the vessel using traditional VR/XR devices. We also propose and implement an efficient computer vision-based MR technique to estimate and display detected vessels effectively and precisely. The vessel detection model is trained using synthetic images. So, we built and made available a dataset composed of 99,000 images. Finally, we also estimate distances of the classified elements, showing all the information in an AR-based interface. Although the probe is wired-connected, it allows for the vessel to stand in deep positions, reducing its exposure and introducing a new way for submarine maneuvers and operations. We validate our proposal through a user experience experiment using 19 experts in periscope operations.

Abstract:

Media is needed in the learning process to support practicum activities. Practicum tools can be made with simple materials, but must meet the standards or eligibility of the tool. This study aims to make a practicum tool in the form of a simple periscope as an optical learning medium in schools. Periscope is an optical instrument used to see objects from hidden places. Usually, periscopes are used on submarines. However, in this study a simple periscope was made from a flat mirror which can be used as a learning medium in schools. This research is experimental research with the stages of preparation, manufacture and testing of tools. The simple periscope that has been designed is a flat mirror periscope made of PVC pipe, L pipe, and a flat mirror. The results of a simple periscope test in the field are being able to see objects clearly as far as the eye can see, the image shape obtained is virtual, upright, and the same size, while the focal length is half of the object distance

Abstract:

TRIZ methodology provides an opportunity for improving the classical engineering approach based on personal knowledge and experience. This paper presents the application of TRIZ methods for improving vehicle maintenance where special equipment is installed. A specific problem is the maintenance of the periscopes with heating system. Protective glass panels with heating system are rectangular glass elements. Their purpose is to perform mechanical protection of built-in prisms and provide heating of the prisms. Aging and long-term use leads to failure of these elements. The practice requires solutions in order to extend the lifetime of the system. New solution is evaluated by simulation and experiment.

Abstract:

This study was conducted to describe the kinematics of bodyroll and investigate whether bodyroll was propelled primarily by the turning effect of the fluid forces (external torque) or by the reaction effect due to the acceleration of the limbs. The performances of 11 competitive swimmers were recorded using two panning periscopes, and the three-dimensional movement of the subjects was reconstructed from digitized video recordings. The external torque acting on the whole body was determined as the first time-derivative of the angular momentum of the whole body. The reaction effect of limb acceleration was determined as the first time-derivative of the angular momenta of the limbs. Shoulder roll and hip roll angles changed synchronously with the stroke frequency but their amplitudes were substantially different, indicating that the bodyroll consisted of a roll of the entire torso and a twist of the torso. The overall contribution of the external torque was to propel bodyroll, while that of the reaction effects of limb accelerations was to resist bodyroll. These results clearly indicate that the primary source for propelling bodyroll was the external torque. Implications towards the mechanical interactions among bodyroll, stroke frequency, and forward propulsion in front crawl swimming were discussed.

Abstract:

Abstract A periscope is an optical device whose function is to allow sighting of objects that are not in direct line of sight with the observer Eye/Screen/Detector. The concept behind the periscope is tilting the optical axis by breaking the rays of light with a mirror or prism so that the image is obtained in the desired location. The periscope has a variety of uses, many of which belong to the military realm. For example, observing from submarines above the sea level surface, looking at the war zone from inside of a tank, directing light into hidden places and more. In this article, the authors will review a new development based on wave guide concept which composes a tube with light reflective walls. This allows us to build a significantly Small-dimensional periscope with respect to a standard periscope that does not use lenses. The authors will also review a number of applications suitable for the reflection periscope.

Abstract:

According to the structure and mechanical characteristics, a CFRP (carbon fiber reinforced plastic) periscope outer tube was designed. The parameters were determined such as fiber orientation angles, number of layers, proportion of fiber with different angles, and stacking sequences. A finite element model was built for the analysis of bending strength and modal. A CFRP periscope outer tube specimen was processed for the bending performance test. The results of simulation and experiments show that the CFRP periscope outer tube could meet the requirements.

Abstract:

Periscope is a live video-streaming smartphone application (app) that allows any individual with a smartphone to broadcast live video simultaneously to multiple smartphone users around the world. The aim of this review is to describe the potential of this emerging technology for global pathology education. To our knowledge, since the launch of the Periscope app (2015), only a handful of educational presentations by pathologists have been streamed as live video via Periscope. This review includes links to these initial attempts, a step-by-step guide for those interested in using the app for pathology education, and a summary of the pros and cons, including ethical/legal issues. We hope that pathologists will appreciate the potential of Periscope for sharing their knowledge, expertise, and research with a live (and potentially large) audience without the barriers associated with traditional video equipment and standard classroom/conference settings.

Abstract:

This technical note describes a number of half-periscope devices designed to permit distortion-free records of the underwater motions of a swimmer to be obtained conveniently, at low cost, and without risking damage to the recording equipment. The basic design consists of a camera and camera support system, a mirror and mirror support system, and a wave deflector. Several variations of this half-periscope design and setup are described. The main advantages of the use of such periscope systems are their light construction and the consequent ease with which they can be transported and set up, their versatility with respect to the positions at which they can be placed around a pool, and the flexibility provided by variations in design and setup.

Abstract:

Live broadcast, being in the monopoly of the traditional media in the past, has become a broadcasting opportunity accessible to much more people thanks to the developing digital technology nowadays. This opportunity is even available to anybody using a cellular phone through applications that make live streaming possible by a single touch. Periscope, which is a mobile live streaming application, is one of them. This study aims to identify, classify and reveal the properties of various reporting and interviewing styles in the new media by conducting the quantitative and qualitative content analysis and discourse analysis of the live streaming of the professional and citizen reporters on Periscope. Thus, also the answer to the question, whether the content produced on Periscope is in compliance with the format of that medium is investigated. In this study, it has been questioned what the data at hand points for facilitating the professionals, who use Periscope independently from their roles within the conventional media or as a complementary to their roles in the conventional media and the citizens, who use it for journalistic purposes to create an effective alternative in this new platform.

Abstract:

In this study, we use a conversation analysis framework to understand the systematic organization of interactions in Periscope live video streams, and its crucial features: (a) the talking heads orientation for the video stream, in common with video-mediated communication; (b) the expectation that the streamer should attend to all messages as much as possible; (c) the ‘loose’ organization of viewers’ responses to streamers’ turn-at-talk, as in multi-party chats. We also identify a distinctive design for streamers’ responses to messages, the ‘read-aloud and respond’ practice. These distinctive features are oriented to the highly asymmetrical communicative affordances of Periscope streams. Without precluding other forms of Periscope-based activities, this systematic organization of talk and messages, coupled with the affordances of the application, favors a basic mode of topic initiation resting on a typical and minimal adjacent pair: viewer’s noticing/streamers’ reading and responding. We argue that the particular salience of this organization of topic initiation may account for the emergence of the dominant kind of use for Periscope streams, that is, the online public exposure of youth to strangers in order to elicit some conversation.

Abstract:

Purpose: To describe an endovascular technique combining the octopus and periscope techniques for the treatment of a patient with type V thoracoabdominal aortic aneurysm in order to protect the patient’s visceral circulation. Case Report: An 84-year-old male patient was hospitalized for type V thoracoabdominal aortic aneurysm involving celiac axis, superior mesenteric artery, and both renal arteries. The patient’s aneurysm was successfully treated by combining the octopus technique and periscope techniques. The 1-year follow-up computed tomography angiography showed that the endograft and the branches were patent. The gutters had thrombosed with no signs of endoleak. No spinal cord ischemia or impairment of the renal function was observed during the follow-up. Conclusions: This case is an example of the successful usage of the combined octopus and periscope techniques in protecting the renovisceral arteries arising from a type V thoracoabdominal aortic aneurysm; this combined technique might be applicable in carefully selected patients.

Abstract:

This study examined the involvement of children with specific language impairment (SLI) in a cooperative group task. Subjects consisted of 6 target children with SLI (ages 8;10 to 12;5), 6 target children matched for chronological age (CA), and 6 target children with similar language skills (LS). Each target subject interacted with 2 peers of the same age and gender. This resulted in 54 subjects participating in 18 triadic interactions (each involving 1 target subject and 2 partners). Each triad of children worked together to build a cardboard periscope. Verbal and nonverbal collaborative activity were analyzed during the interactions. All members of the CA and LS triads were highly collaborative and worked and talked together while assembling the periscope. Four of the children with SLI played very minor roles in the cooperative work within their triads. Their verbal contributions were limited, and their nonverbal activity was minimal. When children with SLI did collaborate in building the periscope, they performed less specialized tasks than did their partners.

Abstract:

Several limitations reduce the field of view in radio-interferometry. With an optical array, two of them can be overcome to some extent according to the beam combination method. A beam combination in the pupil plane can completely overcome one of them. In the image plane, a beam combination obeying the rules of geometrical optics can overcome both limitations in principle, but is difficult to achieve in practice. We discuss particularly the real case of a Michelson Stellar Interferometer where a periscope partially re-introduces these limitations, yielding a trade-off between the extension of the field of view and the use of the periscope.

Abstract:

The question of whether anesthetic, analgesic or other perioperative intervention during cancer resection surgery might influence long-term oncologic outcomes has generated much attention over the past 13 years. A wealth of experimental and observational clinical data have been published, but the results of prospective, randomized clinical trials are awaited. The European Union supports a pan-European network of researchers, clinicians and industry partners engaged in this question (COST Action 15204: Euro-Periscope). In this narrative review, members of the Euro-Periscope network briefly summarize the current state of evidence pertaining to the potential effects of the most commonly deployed anesthetic and analgesic techniques and other non-surgical interventions during cancer resection surgery on tumor recurrence or metastasis.

Abstract:

Pollen analysis is an exercise in seeing. The ultimate goal is to see into the past, to send down a periscope and view what went on. The metaphor of the periscope is too limited, however; a video recorder from high in space with resolution in places up to 10 m is more encompassing of what is possible. The images that are retrieved can be of high or low resolution temporally, spatially, taxonomically, and numerically, and they can illustrate local to global changes in plant populations, vegetation, climate, human activity, fire frequency, and plant diseases over decades to millennia. Because each of these entities or phenomena varies spatially and temporally, records of data covering a breadth of scales in space and time are needed. To obtain the highest quality images about a specific phenomenon requires an understanding of the sensing system that accumulated the data. How does the periscope or video recorder work and what are the scaling characteristics of the images that it registers? These characteristics include breadth of coverage, sampling resolution, and sampling density in time, space, and taxonomy. Actualistic and taphonomic studies of Quaternary data covering a variety of temporal and spatial scales have helped provide this understanding, and temporal resolution is just one concern in these studies.

Abstract:

Overview: To describe a new endovascular procedure for acute type A aortic dissection (TAAD) repair. Methods: Between 2013 and 2016, 12 patients (average age 54±9.6 years; 10 men) with acute TAAD (mean EURO score 11.4%±3.2%, range 5–17) and unfit for surgery underwent thoracic endovascular aortic repair (TEVAR) with 2 periscope grafts to preserve blood supply to supra-aortic branches plus bypass grafting as needed. If the ascending aorta was dilated to >40 mm, sternotomy was performed to wrap the ascending aorta and reduce its diameter to accommodate the aortic stent-grafts. Results: All patients were successfully treated. Seven patients required bypass grafting, and most of the patients had periscope grafts to the innominate/right common carotid artery and left common carotid artery; only 3 patients had the left subclavian artery preserved. All patients exhibited good hemodynamics and normal pressures after the procedure. The mean procedure time and blood loss were 4.5±1.0 hours and 217±111.5 mL, respectively. Two patients treated emergently died shortly after surgery from multiorgan failure. The average follow-up duration was 17±14.5 months (range 2–42) in the 10 survivors. The remaining patients recovered and none experienced stent-graft thrombosis, stroke, or peripheral artery embolism during follow-up. Conclusion: A procedure that combines sandwich/periscope grafting with TEVAR, wrapping of the aorta, and supra-arch bypass grafting can be used to treat patients with acute TAAD.

Abstract:

The ITER in-vessel viewing system is vital for detecting and locating damage to in-vessel components such as the blankets and divertors and in monitoring and assisting in-vessel maintenance. This system must be able to operate at high temperature (200°C) under intense gamma radiation (-30 kGy/h) in a high vacuum or I bar inert gas. A periscope viewing system was chosen as a reference due to its clear, wide view and a fiberscope viewing system chosen as a backup for viewing in narrow confines. According to the ITER R&D program, both systems and a metrology system are being developed through the joint efforts of Japan, the U.S., and RF Home Teams. This paper outlines design and technology development mainly on periscope in-vessel viewing and laser metrology contributed by the Japan Home Team.

Abstract:

A partir da descrição e análise do uso do jornalismo selfie nos perfis de quatro veículos jornalísticos nos aplicativos Periscope, Facebook, Instagram e Snapchat, o presente artigo busca trazer características e tendências que contribuam para as pesquisas sobre essa prática jornalística, especificamente em dois tipos de formatos de conteúdo: as transmissões ao vivo e as narrativas de imagens instantâneas. Metodologicamente, é um estudo de cunho teórico-analítico, desenvolvido a partir de revisão bibliográfica e observação assistemática dos objetos em questão. Uma busca aleatória foi realizada no caso do Facebook Live e Periscope. Já no Instagram Stories e Snapchat, a coleta foi feita através da observação regular em dez dias. Conclui-se que o jornalismo selfie é um modelo recente, mas que já está sendo utilizado pelos principais veículos do mundo, principalmente porque as mídias sociais apresentam potencialidades para a apropriação desse tipo de jornalismo na transmissão de notícias.

Abstract:

Changes at the cell surface enable bacteria to survive in dynamic environments, such as diverse niches of the human host. Here, we reveal “Periscope Proteins” as a widespread mechanism of bacterial surface alteration mediated through protein length variation. Tandem arrays of highly similar folded domains can form an elongated rod-like structure; thus, variation in the number of domains determines how far an N-terminal host ligand binding domain projects from the cell surface. Supported by newly available long-read genome sequencing data, we propose that this class could contain over 50 distinct proteins, including those implicated in host colonization and biofilm formation by human pathogens. In large multidomain proteins, sequence divergence between adjacent domains appears to reduce interdomain misfolding. Periscope Proteins break this “rule,” suggesting that their length variability plays an important role in regulating bacterial interactions with host surfaces, other bacteria, and the immune system.

Abstract:

Abstract BodyThe H2020/PERISCOPE project, including 32 partners from European universities & agencies, began 1st November 2020 and will last 36 months. The overarching objectives of PERISCOPE are to map and analyse the unintended impacts of the COVID-19 outbreak; develop solutions and guidance for policymakers and health authorities on how to mitigate the impact of the outbreak; enhance Europe’s preparedness for future similar events; and reflect on the future multi-level governance in the health as well as other domains affected by the outbreak. During this session we will report about early lessons learnt from the mapping and assessments of the impacts of the COVID-19 outbreak on mental health at national and subnational level in the EU with respect to individuals, communities and societies. Further, we will comment on their comparability. The aim is to explore differences between countries regarding the occurrence of mental ill health, and especially the impact on vulnerable groups, and how this is related to exposure to SARS-CoV-2, differences in policies over time, and effects on the economy. We will reflect on the short- and long-term consequences on mental health and health inequalities, report on the ongoing development of holistic policy guidelines for health authorities & other authorities, and from the analysis of multilevel governance, at local, regional and national level, memberstate – EU-level, and EU - global governance level. PERISCOPE will continue collecting data and updating a common data ”Atlas”, which would lead the consortium to engage in modelling and experiments to provide “continuous nowcasting” of the outbreak.DisclosureNo significant relationships.
