Remote rendering for VR is a technology that enables high-quality VR on low-powered devices. This is realized by offloading heavy computation and rendering to high-powered servers that stream VR as video to the clients. This article focuses on one specific issue in remote rendering when imperfect frame timing between client and server may cause recurring frame drops. We propose a system design that executes synchronously and eliminates the aforementioned problem. The design is presented, and an implementation is tested using various networks and hardware. The design cannot drop frames due to synchronization issues but may on the other hand stall if temporal disturbances occur, e.g., due to network delay spikes or loss. However, experiments confirm that such events can remain rare given an appropriate environment. For example, remote rendering on an intranet at 90 fps with a server located approximately 50 km away yielded just 0.002% stalled frames while rendering with extra latency corresponding to the duration of exactly one frame (11.1 ms at 90 fps). In a LAN without extra latency setting, i.e., with latency equal to locally rendered VR, 0.009% stalls were observed while using a wired Ethernet connection and 0.058% stalls when using 5 GHz wireless IEEE 802.11 ac.

The Impact

The integration between art and science is required for the student in the department of architecture. This paper concentrates on the importance of integration between artistic skills and scientific abilities for the student to achieve high quality level of learning in the department of architecture in Iraq. It analyses the criteria of the architectural education and the educational method used. It demonstrates the integration relationship between art, science and architecture. It follows a descriptive analyses methodology to investigate the skills and abilities required for the student to cope with the criteria of architectural education. It conducted a case study on students in the department of architecture in Iraq to explore the impact of having these skills and abilities on the student’s progression. It explains why a few students only graduate with high grades. The results obtained showed that the integration between artistic skills and scientific abilities is very important for the students. On the other hand, developing the artistic skills is harder than developing the scientific abilities in architectural education.

Modes Of Governance

This chapter demonstrates how the introduction of large screens to contemporary public spaces function to assimilate diverse arts, commercial, and public forms into a conservative regime. On the one hand, the new opportunities that accompany the large public screens are subverted by the logic of capitalist accumulation, which informs a public address designed to achieve high volumes of individual engagement, rather than high quality public engagement. On the other hand, new opportunities to enhance public engagement are subjected to bureaucratic modes of governance, which pre-emptively censor content such that it extends and satisfies conservative regimes of early broadcast regulation. The authors argue that the confluence of capitalist and bureaucratic regimes governing big screens effectively balkanise audiences, valorise nondemocratic forms of participation, and privatise public spaces.

For a quarter of a century we have been engaged in a systematic examination of high-quality photographic (optical) sky surveys in the search for new celestial bodies of various kinds. It took about 5000 hours to cover the whole northern celestial hemisphere and half of the southern one. In total, about 12000 new objects were discovered. From the very beginning of our programme we also searched for objects (or groupings of them) of rather peculiar morphology. The motivation was to detect objects revealing exceptional physical processes, on the one hand, but also to discover constructions possibly created by advanced extraterrestrial civilizations (ETCs), on the other hand. A number of very peculiar objects were indeed found (these were mostly studied in detail later), but none of these appeared likely to be the product of alien masterminds. We may conclude that at least within about 10000–20000 light-years around the Solar system no highly advanced ETCs intend to reveal themselves through such objects.

SummaryImproved designs of refractive correctors produce excellent images with fast telescopes such as those with an F/1.5 prime focus and F/3.5 secondary focus. The fields are flat and there is compensation for the chromatic effect caused by windows. Disadvantages of such correctors are that stray light is produced at the optical surfaces, the elements must be supported at their edges, prerequisite high quality glass is available in only limited sizes, and all wavelengths are not transmitted.Reflective correctors, on the other hand, can produce diffraction limited images at all wavelengths and the mirrors can be supported across their backs as well as at their edges. Disadvantages are that the images are degraded by any substantial window (such as a detector faceplate), there is more central obstruction, and the correctors are sometimes very large and heavy.Except, perhaps, for a specialized telescope, such as one devoted to multi-object slit spectroscopy using fibres, the refractive corrector is preferable at fast foci.A good combination is a Ritchey-Chretien (R-C) telescope with refractive correctors at the fast prime and secondary foci, and a reflective corrector-magnifier for the slow infrared focus.

In recent decades, different concepts in quality management in textile industries have been introduced. Quality is a highly significant concept and also is the most basic challenge for textile industries. What we called controlling in the past, now has been replaced by “quality control”. Among these strategies, production and noble thought in order to recognize and remove not valuable resources on one hand, and six sigma in order to recognize and remove error elements in the process on the other hand, have developed the textile factories. Six sigma and noble methodology are two very strong strategies in for textile companies to reach success and have high quality products. Noble methodology causes a cut in the expenses through optimizing the process whereas six sigma is related to the customers’ expectations or needs. It also improves quality through measuring and controlling the deficits. This study is an attempt to improve textile products through two views: six sigma and noble methodology. Each of them this objective by its own .

Cobalt Radiation

X-ray diffraction (XRD) is a commonly used technology to identify crystalline phases. However, care must be taken with the combination of XRD configuration and sample. Copper (most commonly used radiation source) is a poor match with iron containing materials due to induced fluorescence. Magnetite and maghemite are analysed in different configurations using copper or cobalt radiation. Results show the effects of fluorescence repressing measures and the superiority of diffractograms obtained with cobalt radiation. Diffractograms obtained with copper radiation make incontestable phase identification often impossible. Cobalt radiation on the other hand yields high quality diffractograms, making phase identification straightforward.

Настоящая статья посвящена исследованию проблемы перевода англоязычного заголовка на русский язык с целью выявления его особенностей и привлекаемых переводческих приемов. Авторами подчеркивается актуальность проведенного исследования ввиду растущей потребности быстрого и качественного перевода публицистических текстов и собственно заголовков как ключевого элемента публикации. В работе приводятся определения понятия «заголовок»; выделяются его функции; подчеркивается противоречивый характер заголовка: он может выступать как самостоятельная речевая единица и как равноправный элемент произведения; раскрываются особенности англоязычного заголовка, а также особенности газетно-информационного стиля современного английского языка. Авторы подробно рассматривают переводческие трансформации, привлекаемые для перевода англоязычных заголовков на русский язык, на примере заголовков периодических изданий Великобритании и США. На основе сравнительно-сопоставительного анализа текстов оригинала и перевода авторам удалось выявить лексические, грамматические и стилистические особенности, используемые в англоязычных газетных изданиях. В статье отмечается ключевая роль заголовка в произведении, а также факт особой ответственности в части перевода данного элемента произведения, поскольку именно корректно составленный и переведенный заголовок обеспечивает привлекательность и конкурентоспособность публикации в целом. The article is devoted to the problem of translation of English headlines into Russian to identify headline peculiarities and employed translation shifts. The authors stress the relevance of the conducted study due to the growing need for quick and high quality translation of social-political texts and headlines playing a key role in them. The paper provides a number of definitions for the term «headline»; points out the functions of the headline; stresses the controversial character of the headline: on the one hand, it is an independent speech unit, and on the other hand, it can be treated as an equal element of a text; identifies the peculiarities of English headlines as well as the peculiarities of the newspaper style of the modern English language. The authors look into the translation transformations employed when translating English headlines into Russian as exemplified by the British and American periodicals. Basing on the comparative analysis of the source texts and translations, the authors managed to identify some lexical, grammar, and stylistic peculiarities employed in the English newspapers. The article also notes the key role of the headline and the significance of its translation since it is a correctly composed and then translated headline which provides the attractiveness and competitiveness of a published work.

The process of stock opname of goods in a business is something that must be done regularly to control the business assets. The stock opname process generally requires a lot of money and time, especially in businesses that have many branch locations. During the implementation of stock opname, sales transactions are usually stopped so that the stock does not change. As a result, the longer the time for this process is required, the greater the loss. In addition, extra costs are also incurred when the implementing manager is sent to each branch location where the stock opname will be carried out. Due to the high costs and losses incurred, this stock opname is usually only done a few times a year. On the other hand, the low frequency of stock opname has an impact on increasing business losses due to loss of assets that cannot be detected early. This study aims to increase the effectiveness of the stock opname process to minimize losses that occur during the stocktaking process or losses due to delays in handling the loss of goods assets. The results of this study indicate that the new system design allows the stock opname process to be carried out remotely without the presence of a manager and without stopping sales transactions, so as to reduce operational costs. The frequency of stock opname can also be carried out more frequently so that if there is a loss of assets, it can be immediately identified and action is taken to avoid high business losses. The result of software testing using the Blackbox Testing method shows that the application can run well and the result of User Acceptance Testing shows the acceptance of respondents at 87%, which means that respondents accept the solutions offered well.

Indonesia gets demographic bonus in 2015-2035. Demographic bonus is when the number of productive population of the age of 15-64 years reaches about 70% or about 180 million people and the rest is about 30% or about 60 million people of unproductive age. The demographic bonus is like a double-edged sword. This demographic bonus becomes a profitable phenomenon on the one hand and on the other hand can be disastrous for a country. Beneficial and potential if a country is able to prepare its young generation with a quality generation and vice versa would be disastrous if the state is unable to prepare its human resources. High quality human resources both in terms of education, health, skills so as to compete in the world of work. This phenomenon is of course interesting to be studied further, especially how the opportunities and challenges for diversity in Indonesia.
