Mixed reality is a term which covers a wide range of computer and real world interaction. This name refers to the picture shown on the display device, which consists of real and virtual elements. These elements are mixed in some proportion, so we may distinguish between augmented reality (where the real world dominates) and augmented virtuality (where the virtual world dominates). In most of cases a flat (2D) live image is processed, which makes this technology available in smartphones, car navigation systems etc. In the engineers world the mixed reality is used mainly in simulators and trainers, but also as supporting technology during manufacturing, assembly or maintenance process. This paper discuss different approach: mixed reality as a tool supporting programming of the robot. The main goal was to reproduce a path given by operator in off-line programming software using the visual representation of a real object. The system should be regarded as experimental one, because of early stage of development. It allows defining the coordinates of discrete points or to discretize the path and save this data for further processing. The operator should care the rest of programming task, but the use of the robot is reduced to minimum at this stage. The major disadvantages of the mentioned method are problems with accuracy and the invariable orientation of the tool used by the robot during the process they may be eliminated by using better video equipment and the specialized image processing routine. This paper presents the main assumptions of the method along with a possible solution of the problem.

Although Component-Based System (CBS) increases the efficiency of development and reduces the need for maintenance, but even good quality components could fail to compose good product if the composition is not managed appropriately. In real world, such as industrial automation domain, this probability is unacceptable because additional measures, time, efforts, and costs are required to minimize its impacts. Many general optimization approaches have been proposed in literature to manage the composition of system at early stage of development. This paper investigates recent approach es used to optimize software architecture. The results of this study are important since it will be used to develop an efficient optimization framework to optimize software architecture in next step of our ongoing research.DOI: 10.18495/comengapp.11.033036

Abstract The article explores the main elements of the creation a proinnovation policy in Poland as a new case of public policy. It analyses the current status of proinnovation policy in Poland and the relationships implicit in the Polish National Innovation System. The findings support the conclusion that Polish proinnovation policy and the system through which it is enacted are at an early stage of development which is characteristic of co-called ‘catching-up’ countries. The findings show that there is a need for the strategic and holistic management of this type of sub-functional system to enable it to support SMEs in the development of their capacity for innovation. This should include a wide range of public and private institutions in the context of multi-stage governance.

Fifty years ago, Tibetan art and architecture were fields in an early stage of development in the West. Early Western knowledge of Tibetan art and architecture was largely due to the pioneering work of early 20th-century scholars such as Giuseppe Tucci, Joseph Hackin, and Alice Getty. These fields have developed significantly over the past few decades, for multiple reasons. These reasons include general growth in interest in Tibetan culture and religion following the Chinese occupation of Tibet, and in the Tibetan diaspora, from the 1950s onward. The Cultural Revolution in the 1960s and 1970s in China led to the destruction of a tremendous amount of Tibetan art and architecture, and to the displacement within China of many works of Tibetan art that were not destroyed. However, the opening of China to the outside world in the post-Mao era led to the growing availability of Tibetan art on international art markets and gave foreign scholars access to surviving architectural monuments. This has led to a rapid growth in the understanding of Tibetan art history and stylistics. This work has been undertaken by a wide range of scholars, from North America and Europe, as well as Japan and India. More recently, there has also been considerable growth in scholarship within China by Tibetan and Han Chinese scholars.

Лук репчатый – важнейшая овощная культура в стране. Величина и качество урожая в значительной мере определяется эффективностью борьбы с сорняками. При этом необходим поиск новых более эффективных схем применения гербицидов, обеспечивающих снижение их норм внесения в сочетании с повышением эффективности. На луке необходимо очищать посевы от сорняков в период флаг-листа культуры до двух настоящих листьев, а сорняки – в фазе семядоли – одного настоящего листа. Злаковые сорняки уничтожают применением широкого ассортимента граминицидов. Двудольные – как в культуре предшественника в севообороте, так и по вегетирующим растениям лука. В 2019–2020 годах были испытаны системы гербицидов, включающие внесение Реглон Форте 2,0 л/га за 1–3 дня до всходов лука в сочетании с применением Гоал 2Е в нормах 0,2, 0,25 и 0,3 л/га в фазу первого настоящего листа у лука (длина 3,2–3,7 см). Опыты проводили на опытном поле Всероссийского научно-исследовательского института овощеводства – филиале Федерального научного центра овощеводства (Московская область). Почва участка – аллювиальная, луговая, среднесуглинистая с содержанием гумуса 3,0–3,2%, рН солевой вытяжки 5,9, хорошо обеспечена подвижным фосфором (22–26 мг на 100 г почвы) и слабо калием (12–16 мг на 100 г почвы). Агротехника возделывания при капельном орошении была общепринятой для Нечерноземной зоны России. Учет эффективности проводили согласно стандартных методик. Размер учетных делянок – 12 м2. Повторность опытов четырехкратная. Установлено, что на посевах лука со средним и слабым уровнем засоренности, перспективны послевсходовые обработки Гоал 2Е в оптимальной норме 0,25 л/га начиная с фазы первого настоящего листа культуры по сорнякам в ранней стадии развития на фоне предвсходового внесения Реглон Форте 2,0 л/га. При этом главный фактор успеха применения Гоал 2 Е в первую очередь – фаза развития сорняков. Максимальный эффект можно достигнуть, когда значительное большинство из них будет в момент обработки в фазе семядолей. Onions are the most important vegetable crop in the country. The size and quality of the crop is largely determined by the effectiveness of weed control. At the same time, it is necessary to search for new more effective schemes for the use of herbicides, which ensure a reduction in their application rates in combination with an increase in efficiency. On the onion, it is necessary to clear the crops from weeds during the flag-leaf culture to two real leaves, and weeds – in the cotyledon phase – one real leaf. Cereal weeds are destroyed by using a wide range of graminicides. Dicotyledons – both in the culture of the predecessor in the crop rotation, and on vegetative onion plants. In 2019–2020, herbicide systems were tested, including the introduction of Reglon Forte 2.0 l/ha 1–3 days before onion shoots, in combination with the use of Goal 2E in the norms of 0.2, 0.25 and 0.3 l/ha in the phase of the first real leaf in onions (length 3.2–3.7 cm). The experiments were carried out at the experimental field of All Russian Research institute of Vegetable Growing – branch of Federal Scientific Centre of Vegetable Growing (Moscow region) The soil of the site is alluvial, meadow, medium loamy with a humus content of 3.0–3.2%, a pH of salt extract of 5.9, well provided with labile phosphorus (22–26 mg per 100 g of soil) and weakly potassium (12–16 mg per 100 g of soil). The agricultural technique of cultivation with drip irrigation was generally accepted for Non-chernozem zone. The efficiency was taken into account according to standard methods. The size of the accounting plots is 12 m2. The repetition of experiments is fourfold. It was found that on onion crops with medium and low levels of infestation, post-emergence treatments of Goal 2E in the optimal rate of 0.25 l/ha are promising, starting from the phase of the first real leaf of the crop for weeds in the early stage of development against the background of pre-emergence application of Reglon Forte 2.0 l/ha. At the same time, the main factor for the success of the use of Goal 2 E, first of all, is the phase of weed development. The maximum effect can be achieved when a significant majority of them will be in the cotyledon phase at the time of processing.

For many years in car development the future customer was first represented by templates. Today and in fact for a long time now CAD tools are solely used for designing a car and therefore man had to be integrated into that environment as well. 1986 the German car industry joined in a research program to produce a common man model for the use in automotive design. This program called RAMSIS has been in practical use at BMW since the early nineties. All “static” situations can be assessed with RAMSIS today including dynamic movements of arms and legs. For entry and egress and for the final confirmation, three dimensional mock-ups are tested by a number of in-house test subjects. Their body dimensions have to be known in order to compare their assessments with the customer population. Therefore we regularly measure members of the research and development center using all methods, from the conventional yardstick to current laser scanning techniques. Hand in hand with DMU methods Virtual Reality has gained access to development processes. The goal of DMU, to eliminate the time consuming and expensive hardware loops and replace them as much as possible by digital models, is effectively supported by VR techniques that speed up processes by enhancing the man-machine-interaction. There is a wide range of application fields to use these techniques, e.g. design review, assembly and maintenance simulation and training. RAMSIS is integrated in the BMW VR environment with special extensions to allow immersive ergonomic research. Mixed mock-up applications are used to have virtual experiences, to verify or to train assembly procedures at an early stage of development and therefore eliminate problems as soon as possible. New concepts can be evaluated and assessed taking ergonomic aspects and disturbing influences into account.

The article discusses green tourism and notes that green tourism in the regions of Georgia is at an early stage of development, with the potential and desire of the local population as a major user of green services. The proposed system of indicators may be universal for express-evaluation of the state at the regional level. The existing system of green tourism has shown that the state has to change its approaches to the formation of green tourism products (lack of green certification, etc.). The study identified trends in the growth of domestic tourism flows that can be proposed as effective promotion of regional tourism. For the further successful development of green tourism, it is first and foremost necessary to educate the public on a clear understanding of the increase in the price of these tours. One must realize and be aware that the money he or she pays to achieve a high quality of tourism is to serve specific ecological measures, one must feel the result of their implementation. Directions for improving green tourism include management system, ecotourism transport support, infrastructure development and provision of a wide range of services to the population that do not harm the ecological condition of the area, enhances the general ecological culture of the population, introduces new technologies for resource consumption and for waste recycling.

The article deals with the preconditions of differentiation of forms of pre-trial investigation in Ukraine in the 18th–19th centuries. The concept of investigation of misdemeanours as a form of pre-trial investigation at different stages of social development are considered. The base source of the Russian Empire is examined, with the aspects of using of the term “investigation of misdemeanours” in law enforcement practice thoroughly covered. It is established that this term at the legislative level and in the literary sources held for a long time is subject to transformation in terms of its functional direction. The paper offers a description of the study of the early stage of development and a comparison with the modern form of pre-trial investigation. It is established that at all stages of its development there is a common feature: the provision of a simplified order.The article presents the key differences between the knowledge at the early stage of its creation and the modern form of pre-trial investigation. However, the investigation of misdemeanours starts from the moment of the illegal act until the end of the pre-trial investigation. At first, this investigation of misdemeanours had few signs of research verification. The collected materials were examined by the proceedings and could not be determined by full evidence without appropriate “legalization” procedures. The investigation of misdemeanours had not clearly defined a procedural form and was not limited to specific deadlines, and depended almost entirely on the inner convictions of the individual who conducted this knowledge. In the legislation of the pre-revolutionary period, the investigation of misdemeanours should be carried out by a wide range of authorized persons (police ranks, military and civilian authorities, clergy, government officials, village elders, and others). The investigation of misdemeanours was carried out in everything without exception of crime, regardless of its severity at those times.It is proved that the modern model of pre-trial investigation represents the positive historical experience and the right opinion. Today we can observe a consistent procedure of the implementation of the exercise, a special circle of authorized persons, and the introduction of a balance of appropriate differentiation of forms of pre-trial investigation.

PurposeThis paper presents a reclassification of markers for mixed reality environments that is also applicable to the use of markers in robot navigation systems and 3D modelling. In the case of Augmented Reality (AR) mixed reality environments, markers are used to integrate computer generated (virtual) objects into a predominantly real world, while in Augmented Virtuality (AV) mixed reality environments, the goal is to integrate real objects into a predominantly virtual (computer generated) world. Apart from AR/AV classifications, mixed reality environments have also been classified by reality; output technology/display devices; immersiveness as well as by visibility of markers.Design/methodology/approachThe approach adopted consists of presenting six existing classifications of mixed reality environments and then extending them to define new categories of abstract, blended, virtual augmented, active and smart markers. This is supported with results/examples taken from the joint Mixed Augmented and Virtual Reality Laboratory (MAVRLAB) of the Ulster University, Belfast, Northern Ireland; the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy and Santasco SrL, Regio Emilia/Milan, Italy.FindingsExisting classification of markers and mixed reality environments are mainly binary in nature and do not adequately capture the contextual relationship between markers and their use and application. The reclassification of markers into abstract, blended and virtual categories captures the context for simple use and applications while the categories of augmented, active and smart markers captures the relationship for enhanced or more complex use of markers. The new classifications are capable of improving the definitions of existing simple marker and markerless mixed reality environments as well as supporting more complex features within mixed reality environments such as co-location of objects, advanced interactivity, personalised user experience.Research limitations/implicationsIt is thought that applications and devices in mixed reality environments when properly developed and deployed enhances the real environment by making invisible information visible to the user. The current work only marginally covers the use of internet of things (IoT) devices in mixed reality environments as well as potential implications for robot navigation systems and 3D modelling.Practical implicationsThe use of these reclassifications enables researchers, developers and users of mixed reality environments to select and make informed decisions on best tools and environment for their respective application, while conveying information with additional clarity and accuracy. The development and application of more complex markers would contribute in no small measure to attaining greater advancements in extending current knowledge and developing applications to positively impact entertainment, business and health while minimizing costs and maximizing benefits.Originality/valueThe originality of this paper lies in the approach adopted in reclassifying markers. This is supported with results and work carried out at the MAV Reality Laboratory of Ulster University, Belfast–UK, the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste-Italy and Santasco SrL, Regio Emilia, Milan–Italy. The value of present research lies in the definitions of new categories as well as the discussions of how they improve mixed reality environments and application especially in the health and education sectors.

Abstract Background Three-dimensional (3D) echocardiographic data acquired from transesophageal (TEE) window are commonly used in planning and during percutaneous structural cardiac interventions (PSCI). Purpose We hypothesized that innovative, interactive mixed reality display can be integrated with procedural PSCI workflow to improve perception and interpretation of 3D data representing cardiac anatomy. Methods 3D TEE datasets were acquired before, during and after the completion of PSCI in 8 patients (occluders: 2 atrial appendage, 2 patent foramen ovale and 3 atrial septal implantations and percutaneous mitral commissurotomy). 30 Carthesian DICOM files were used to test the feasibility of mixed reality with commercially available head-mounted device (overlying hologram of 3D TEE data onto real-world view) as display for the interventional or imaging operator. Dedicated software was used for files conversion and 3D rendering of data to display device (in 1 case real-time Wi-Fi streaming from echocardiograph) and spatial manipulation of hologram during PSCI. Custom viewer was used to perform volume rendering and adjustment (cropping, transparency and shading control). Results Pre- and intraprocedural 3D TEE was performed in all 8 patients (5 women, age 40–83). Thirty selected 3DTEE datasets were successfully transferred and displayed in mixed reality head-mounted device as a holographic image overlying the real world view. The analysis was performed both before and during the procedure and compared with flatscreen 2-D display of the echocardiograph. In one case, real-time data transfer was successfully implemented during mitral balloon commissurotomy. The quality of visualization was judged as good without diagnostic content loss in all (100%) datasets. Both target structures and additional anatomical details were clearly presented including fenestrations of atrial septal defect, prominent Eustachian valve and earlier cardiac implants. Volume rendered views were touchlessly manipulated and displayed with a selection of intensity windows, transfer functions, and filters. Detail display was judged comparable to current 2-D volume-rendering on commercial workstations and touchless user interface - comfortable for optimization of views during PSCI. Conclusions Mixed reality display using a commercially available head-mounted device can be successfully integrated with preparation and execution of PSCI. The benefits of this solution include touchless image control and unobstructed real world viewing facilitating intraprocedural use, thus showing superiority over virtual or enhanced reality solutions. Expected progress includes integration of color flow data and optimization of real-time streaming option.

The helium cooled Gas Fast Reactor (GFR) is one of the six reactor concepts selected in the frame of the Generation IV International Forum. Since no gas cooled fast reactor has ever been built, a medium power demonstrator reactor — named ALLEGRO — is necessary on the road towards the 2400MWth GFR power reactor. The French CEA completed a wide range of studies on the early stage of development of ALLEGRO, and later the ALLEGRO reactor have been developed in several European Union projects in parallel with the GFR2400. The 75 MW thermal power ALLEGRO is recently being developed in the frame of European ALLIANCE project. As a result of the collaboration between CEA and MTA EK new improvements were done in the CATHARE modeling of ALLEGRO. In particular, the capability of simulation of breaks located in the crossduct (concentrically arranged pipes with the hotduct located inside the colduct) has been developed. A first scenario of hotduct break has been simulated, that does not lead to the depressurization of the system because of the crossduct technology. Nevertheless this transient leads to a high bypass of the core. Then a scenario of full rupture of the hotduct and the colduct has been tested, leading to beyond design state with depressurized situation combined with a large bypass of the core. However this study shows that the peak cladding temperature can be kept below the cladding melting point using nitrogen injection. In this paper the CATHARE model implemented for the crossduct rupture scenario and the results of the simulation are presented and discussed.
