Opis:
In recent years, with the increasing popularity of IoT, the rapid growth of smartphone usage enabled by the increase adoption of Internet services and the continuously decreasing costs of these devices and services has led to a huge increase in the volume of data that governments can use in the context of smart city initiatives. The need for analytics is becoming a requirement for smart city projects such as city dashboards to provide citizens with an easy to understand overview of the city. As such, data should be analyzed, reduced and presented in such a way that citizens can easily understand various aspects of the city and use this information to increase quality of life. In this paper, we firstly present the context and the start of the design and implementation of proposed solution for real-time data processing in smart cities, mainly an analytics processing pipeline and a dashboard prototype for this solution, named My City Dashboard. We focus on high scalability and modularity of this platform.

Opis:
The possible radical nitration reactions of isooctane fuel with nitromethane propellant, which is generally used as an additive in fuel formulations, were thermodynamically investigated both at room temperature and at a higher temperature of 691.15 K. The temperature of 691.15 K was chosen because it is the auto-ignition temperature of isooctane and nitromethane and has the potential to mimic better engine conditions. The computational calculations were performed at the theoretical level of DFT UB3LYP/cc-pVDZ. Four different nitration reactions and nitrated products were considered and interpreted in detail. The most and the least favorable nitrations were observed at the primary and secondary carbons of isooctane at 691.15 K, respectively. Four of the designated reactions were endothermic at this temperature. The other outcome of this study was that there was a direct relationship between the thermodynamic tendencies of the considered reactions and the ballistic performances (detonation velocities, detonation pressures, and specific impulses) of their nitrated products. The thermodynamic properties of heats of combustion and deflagration temperatures were calculated via empirical formulations based on the stoichiometry and some other structural parameters of the energetic materials. The results for nitromethane and the nitro-isooctane products were examined.

Opis:
В статті окреслені внутрішні проблеми Узбекистану, серед яких слід назвати проблему бідності, масового безробіття, нестачі сільськогосподарської землі і водних ресурсів, екологічні проблеми. Значною мірою ці проблеми обумовлені швидким зростанням населення. Узбекистан намагається  вирішити ці проблеми шляхом ліберальних ринкових реформ та багатовекторної зовнішньої політики, розвиваючи одночасно політичні та торгово-економічні відносини з різними країнами, зокрема, з Китаєм, США, Євросоюзом, Туреччиною, Південною Кореєю, Росією та іншими країнами-членами Євразійського економічного союзу (ЄАЕС). В статті показано, що обсяги торгівлі Узбекистану із західними країнами, а також обсяги західних інвестицій в економіку цієї країни в цілому залишаються, принаймні зараз, невисокими. Робиться висновок, що для США Узбекистан є цікавим головним чином в геополітичному і військово-стратегічному аспектах, особливо зараз, після виводу американських військ із Афганістану. ЄС значно більше, ніж США, зацікавлений в розвитку торгово-економічних відносин з Узбекистаном. Нова угода між Узбекистаном і ЄС про розширене партнерство і співробітництво створить більш сприятливі умови для економічного співробітництва і торгівлі, зростання європейських інвестицій в економіку Узбекистану. Проте, здається, що фактор географічної віддаленості Узбекистану від Європи не дасть можливості країнам Євросоюзу займати таке ж провідне місце в зовнішньоекономічних відносинах Узбекистану, яке зараз займають сусідні Китай, Росія та інші країни-члени ЄАЕС. Показано, що найважливішим торгово-економічним партнером Узбекистану є Китай, який розглядає Узбекистан як важливу транзитну країну, через територію якої проходять транспортні коридори для транспортування, перш за все, китайських товарів в країни Європи та інші регіони світу. Китайські інвестиції в економіку Узбекистану невпинно зростають. Євразійський економічний союз (ЄАЕС), зокрема, такі його члени як Росія і Казахстан, також є для Узбекистану найважливішим торгово-економічним партнером. Крім того, Росія є головним ринком праці для мільйонів узбецьких трудових мігрантів. В межах ЄАЕС був створений єдиний ринок праці, трудові мігранти-громадяни країн-членів ЄАЕС користуються соціальними правами країни перебування та можуть вільно пересуватися територією країн-членів ЄАЕС. Ця обставина особливо важлива для Узбекистану, який зацікавлений в покращенні умов перебування своїх трудових мігрантів. Крім того, як свідчать факти, економічна інтеграція в межах ЄАЕС не перешкоджає урядам країн-членів ЄАЕС розвивати інтенсивні політичні і економічні відносини з різними країнами. Враховуючи всю низку гострих соціально-економічних, екологічних і демографічних проблем, які стоять перед Узбекистаном, думається, що в майбутньому неможливо повністю виключати членство Узбекистану в ЄАЕС, особливо, якщо таке членство не завадить узбецькому керівництву й надалі проводити багатовекторну зовнішню політику. Парламент Узбекистану схвалив рішення брати участь в роботі ЄАЕС в якості спостерігача. В грудні 2020 р. ЄАЕС надав Узбекистану такий статус.
The article elucidates the internal problems of Uzbekistan among which one should mention the problem of poverty, mass unemployment, shortage of arable land and water resources, serious ecological problems. To a high degree these problems have been caused by a rapid growth of population. Uzbekistan tries to solve these problems by means of liberal market reforms and the multi-vector foreign policy developing political, economic and trade relations at the same time with different countries, in particular with China, the USA, the EU, Turkey, South Korea, Russia and other countries-members of the Eurasian Economic Union (EAEU). It was shown that volumes of trade of Uzbekistan with the Western countries as well as the level of Western investments remain at least now not high. The conclusion is drawn that for the USA Uzbekistan presents the interest mainly in geopolitical, military and strategic aspects, especially now after the US troops left Afghanistan. The EU is more than the USA interested in developing the trade and economic relations with Uzbekistan. The new agreement between Uzbekistan and the EU on enlarged partnership and cooperation will create more favorable conditions for economic cooperation and trade, growth of European investments into economy of Uzbekistan. Nevertheless it seems that the factor of geographic remoteness of Uzbekistan from Europe will not make it possible for the EU countries to occupy the same place in external economic links of Uzbekistan as the countries-neighbours such as China, Russia and other countries-members of the EAEU. It is shown that China is the most important trade and economic partner of Uzbekistan. China considers Uzbekistan as the important transit country with transport corridors indispensable for transportation first of all of Chinese goods to the countries of Europe and other regions of the world. The Chinese investments into economy of Uzbekistan are constantly growing. The Eurasian Economic Union (EAEU), in particular Russia and Kazakhstan, is also the most important trade and economic partner of Uzbekistan. Besides, Russia is the biggest labour market for millions of Uzbek migrant workers. Within the EAEU the common labour market was created, migrant workers who are citizens of the countries-members of the EAEU enjoy the social rights of the country of stay and may freely move over territories of the countries-members of the EAEU. This fact is especially important for Uzbekistan which is interested in improving living conditions of its migrant workers. Besides, as the facts show, the economic integration within the EAEU does not prevent the governments of the countries-members of the EAEU from developing intensive political and economic relations with different countries. Taking into account the complex of acute socio-economic, ecological and demographic problems facing Uzbekistan it seems that in the future one cannot completely exclude the possibility of membership of Uzbekistan in the EAEU especially if such a membership does not prevent the Uzbek government from pursuing the multi-vector foreign policy. The parliament of Uzbekistan approved the decision to obtain the status of observer at the EAEU. The EAEU granted this status to Uzbekistan in December 2020.

Opis:
Factors contributing to nitrogen removal in a biological aerated filter (BAF) using oyster shell medium have been investigated. The system was operated in parallel with a bio-ball filter. Both filters were fed with a synthetic domestic wastewater containing approximately 25 mg N/dm3 of total nitrogen (TN). The COD of wastewater was 200 mg O2/dm3. The sizes and dissolved oxygen (DO) of the voids within both filters were measured. Results indicated that the oyster shell system performed better with a nitrogen removal of 64.3%. The two systems exhibited a similar COD removal efficiency of approximated 80%. The oyster shell filter showed higher degree of variability in both sizes and DO levels of its void spaces. The condition provided a favorable environment for nitrogen removal through simultaneous nitrification and denitrification (SND). The release of carbonates from oyster shells were minimal, as judged from mass balance analysis of the system using calcium. It is concluded that the function of a SND reactor can be enhanced by using non-uniform filter media such as oyster shells. On the other hand, alkalinity is not a major concern when treating wastewaters with moderate ammonia concentration, such as that of domestic wastewaters.

Opis:
This study focuses on modelling general and individual language change over several decades. A timeline prediction task was used to identify interesting temporal features. Our previous work achieved high accuracy in predicting publication year, using lexical features marked for syntactic context. In this study, we use four feature types (character, word stem, part-of-speech, and word n-grams) to predict publication year, and then use associated models to determine constant and changing features in individual and general language use. We do this for two corpora, one containing texts by two different authors, published over a fifty-year period, and a reference Corpus containing a variety of text types, representing general language style over time, for the same temporal span as the two authors. Our linear regression models achieve good accuracy with the two-author data set, and very good results with the reference corpus, bringing to light interesting features of language change.

Opis:
“Pan-dichoporites” (new informal term) is proposed to unite Cambrian blastozoans, such as Cambrocrinus, Ridersia, and Sanducystis, glyptocystitoid and hemicosmitoid rhombiferans, coronates, blastoids, and Lysocystites. Pan-dichoporite ambulacra have double biserial main axes with brachiole facets shared by pairs of floor (glyptocystitoids), side (blastoid) or trunk (hemicosmitoids, coronates) plates. These axial plates are the first two brachiolar plates modified to form the ambulacral axes. In glyptocystitoids the first brachiole facet in each ambulacrum is shared by an oral and another plate. Hence, these are also two modified brachiolar plates and part of the axial skeleton under the Extraxial Axial Theory (EAT). Pan-dichoporites are also characterized by thecae composed of homologous plate circlets. The unique glyptocystitoid genus Rhombifera bears ambulacral facets on five radial plates, which alternate with five orals. The oral area of Lysocystites (blastoid sensu lato) is very similar, which suggests that rhombiferan radials are homologous with “ambulacrals” of Lysocystites and hence with blastoid lancet plates. This implies derivation of blastoids from glyptocystitoids and suggests that blastoid and coronate radials and deltoids are homologous with rhombiferan infralaterals and laterals. Thus, homologous plate circlets occur in all pan-dichoporites, which strengthens the validity of a pan-dichoporite clade. Under Universal Elemental Homology (UEH), deltoids were homologized with rhombiferan orals, but this is inconsistent with the EAT. Deltoids bear respiratory pore structures and so are perforate extraxial skeletal plates, whereas rhombiferan orals are axial skeleton. The new plate homologies also explain why only five plates form the oral frames of coronates, blastoids and Lysocystites, whereas glyptocystitoids (except Rhombifera) have six oral frame plates; all glyptocystitoids have only five laterals. Hemicosmitoids arose by paedomorphic ambulacral reduction, but the paedomorphosis also affected the thecal plates and stem. Paedomorphosis poses special problems for cladistic character analysis, since the new characters often appear to be plesiomorphic.

Opis:
Ongoing research has indicated important effects on seafarers’ occupational commitment due to gender and family situation. In this study, these findings have been elaborated further by controlling for the effect of perceived work content. Statistical analyses were employed, using a survey material of Swedish seafarers collected from a national register in 2010. The results showed that the effect on occupational commitment of having children at home is strongly positive and statistically significant for women. However, the significance was dependent on the level of satisfaction with the job content. It was suggested that the seafaring occupation could be viewed as a cooping strategy, although only appropriate if the job content is agreeable. Another important family effect was, as expected, the positive effect of having a relative working, or having worked, at sea. This effect was, however, only significant for male seafarers in the age group below the early 40’s. It was concluded that this effect is mainly emotionally driven and not particularly influenced by the actual job content. The results further showed that working in the catering department comes with a strong negative effect on commitment to the seafaring occupation for women. This effect, however, lost its significance after control for job content. It was concluded that the effect of satisfaction with job content on occupational commitment is generally important, with the exception of women, without children, working in the catering department.

Disjoint paths have applications in establishing bottleneck-free communication between processors in a network. The problem of finding minimum delay disjoint paths in a network directly reduces to the problem of finding the minimal disjoint paths in the graph which models the network. Previous results for this problem on chordal graphs were an O(|V| |E|²) algorithm for 2 edge disjoint paths and an O(|V| |E|) algorithm for 2 vertex disjoint paths. In this paper, we give an O(|V| |E|) algorithm for 2 vertex disjoint paths and an O(|V|+|E|) algorithm for 2 edge disjoint paths, which is a significant improvement over the previous result.

Opis:
The most careful and consolidated risk analysis methods, as FTA, ETA, FMEA/FMECA, focus attention on system reliability. But, looking at OHS, a deep analysis on European data on accidents at work and on work environment in general, shows how reliability is only one aspect of safety problem. These methods then are hardly adaptable when the main aim is to obtain a quantitative assessment of risk for workers; besides, Rother methodologies are nearest to OHS but give only qualitative results like HAZOP, or base their analysis on notdimensional values, fixed by analyst on personal experiences, like methods proposed by UNI EN 1050, by standard MIL-STD-882c and by AISS. RATE is proposed as a new quantitative methodology for OHS, particularly dedicated to SMEs considered as the most interesting from these aspect. The paper compares hypothesis and procedures which traditional quantitative methodologies and RATE are based on, to give evidence at the main approach aspects that have to be modified in order to move from reliability to OHS.

Opis:
In this paper, a system of fabric wrinkle measurement was developed which consisted of a fabric wrinkle simulator, scanner and computer. The simulator generated “diamond” wrinkles just like those of the elbow and knee in actual wear. The images of wrinkled fabrics acquired by the scanner were processed with software developed in MATLAB and new characteristics of wrinkle severity (WS) and fabric unevenness (FU) in the warp and weft direction were proposed for the wrinkle characterisation. 15 different fabrics were used to compare the measurement results of the system with those of the AATCC 66-2008 test method. The results showed good agreement of the two methods and at a 45° wrinkle recovery angle, the correlation between the wrinkle recovery angle and WS or FU increased. Therefore it was advised that the wrinkle recovery angle of 45° be measured rather than averaging warp and weft wrinkle recovery angles only when using the AATCC 66-2008 test method. Compared with the AATCC 66-2008 test method, that in this paper can produce more “realistic” wrinkles and measure the wrinkling properties of fabrics in actual wear.
Opracowana metoda polega na wykorzystaniu symulatora, skanera i komputera. Symulator generuje powstanie zmarszczek o kształcie odpowiadającym zmarszczkom na łokciach i kolanach powstałym podczas noszenia odzieży. Obrazy zmarszczek zidentyfikowane za pomocą skanera były przetwarzane za pomocą programu opracowanego w MATLAB. Do dalszej analizy zmarszczek wykorzystywano dwa parametry WS – intensywność zmarszczek i FU – nierównomierność materiału w kierunku wątku i osnowy. Dla porównań wykorzystano 15 różnych tkanin. Porównując wyniki uzyskane za pomocą analizowanego systemu z wynikami uzyskanymi z metody AATCC 66-2008 stwierdzono dobrą zgodność wyników uzyskanych z obydwu metod. Wyciągnięto praktyczne wnioski dotyczące stosowania obydwu metod przy ocenie zmarszczek ubrań po procesie noszenia.
