In the paper flow dynamic similarity criteria have been presented to reflect the macroscopic flow pattern in the combustion chamber of large-scale circulating fluidised bed boilers. The proposed scaling rules have been verified on two cold models of CFB boilers operating in Tauron Wytwarzanie S.A. - El. Lagisza division (scale factor 1/20) and Fortum Power and Heat Poland Sp. z o. o. Czestochowa division (scale factor 1/10) – working with the power of 966 MWth and 120 MWth, respectively. As follows from the results of measurements, regardless of CFB boiler’s geometry the use of a defined set of criterial numbers allows to obtain satisfactory agreement between the suspension density distributions registered in the CFB boilers and scaling models.

Each European Union Member State keeps a register of data on properties located in its territory. The number, type and scope of these properties are determined by each Member State’s needs. The INSPIRE Directive enables the scope of data to be harmonised, and the data to be made available for the purpose of assisting legislators in taking decisions and actions likely to have either direct or indirect impact on the environment. The aim of the study was to indicate the basic differences between the data contained in Polish and Latvian cadastres. Unlike other similar studies analysing the content of data in the cadastre, this article pays special attention to the number of available sets of data about the parcel and its surroundings, the ease of access to these data and the possibility for acquiring them by an interested party without incurring additional fees. This is particularly important in activities related to spatial management and the development of an information society. The results show that in both countries, the decision makers have approached the INSPIRE Directive differently. Direct analyses conducted for the cities of Wrocław (Poland) and Riga (Latvia) demonstrated that the information system in Wrocław contains a considerably greater scope of information available free of charge, is easier to use and offers more services. The Latvian Republic’s spatial information system provides a less-developed scope of information about real estate (without fees) that is dispersed on several websites, which slows down and hinders its use.

The paper approaches an important issue of the phonological similarity of words, relevant for current research in phonotactics, word recognition, production and acquisition, by analyzing the data collected in an experiment in which 30 native speakers of Polish were asked to provide phonologically similar words to 80 nonwords. The study demonstrates that the uncovered patterns of phonological similarity (segment substitutions, deletions and additions, the use of bigrams, trigrams and quadrigrams, noncontiguous sounds and segment metathesis) go beyond the commonly employed concept of neighbourhood density and point to the need to revise the current approaches to phonological similarity of words. It is argued that the experimental results can be attributed to the considerably more complex phonotactic and morphological structure of Polish than English.

This article intends to justify the gap in the research of similarity coefficient driven approaches

and cell formation problems (CFP) based on ratio data in cellular manufacturing systems

(CMS). The actual implication of ratio data was vaguely addressed in past literature, which

has been corrected recently. This research considered that newly projected CFP based on

ration data. This study further revealed the lack of interest of researchers in investigation for

an appropriate and improved similarity coefficient primarily for CFP based on ratio data.

For that matter a novel similarity coefficient named as Generalized Utilization-based Similarity

Coefficient (GUSC) is introduced, which scientifically handles ratio data. Thereafter

a two-stage cell formation technique is adopted. First, the proposed GUSC based method

is employed to obtained efficient machine cells. Second, a novel part allocating heuristic is

proposed to obtain effective part families. This proposed approach is successfully verified on

the test problems and compared with algorithms based on another similarity coefficient and

a recent metaheuristic. The proposed method is shown to obtain 66.67% improved solutions.

The use of virtual reality (VR) has been exponentially increasing and due to that many researchers have started to work on developing new VR based social media. For this purpose it is important to have an avatar of the user which look like them to be easily generated by the devices which are accessible, such as mobile phones. In this paper, we propose a novel method of recreating a 3D human face model captured with a phone camera image or video data. The method focuses more on model shape than texture in order to make the face recognizable. We detect 68 facial feature points and use them to separate a face into four regions. For each area the best fitting models are found and are further morphed combined to find the best fitting models for each area. These are then combined and further morphed in order to restore the original facial proportions. We also present a method of texturing the resulting model, where the aforementioned feature points are used to generate a texture for the resulting model.

Isozyme, RAPD and AFLP markers were evaluated and compared for their ability to determine genetic similarity in a set of 18 parental lines of winter oilseed rape F₁ hybrids developed using CMS ogura. Five isozyme systems, 64 RAPD starters and 23 EcoRI+3/MseI+3 AFLP primer combinations generated 597 polymorphic markers. These polymorphic fragments were chosen for estimation of genetic similarity. Of the total number of polymorphic products, polymorphic zymograms constituted only 3.0% of the markers, 57 RAPD primers 37.7%, and 23 AFLP primer combinations 59.3%. The size of RAPD polymorphic products ranged from 564 to 2100 bp. On average there were four amplified bands per primer, with 61.0% polymorphism. The AFLP polymorphic fragments ranged from 72 to 1352 bp in size. AFLP assays generated 15 bands per primer pair on average and detected roughly four times more bands than with RAPD analysis. The genetic similarity coefficients based on all marker data range from 0.52 to 0.84. The correlation of genetic similarities based on RAPD and AFLP markers was 0.58. Estimated genetic similarity based on isozyme data was not correlated with genetic similarity derived from the two DNA-based markers. The dendrogram constructed with the three types of markers taken together grouped all the winter oilseed rape parental lines into several similar clusters. The genomic distribution and frequency of the RAPD and AFLP markers can serve well as estimators of genetic similarity between parental lines of F₁ CMS ogura hybrids

With the rise of coal mine underground reservoir engineering in the Shendong Mining Area, the space time dynamic evolution prediction of storage coefficient is becoming one of the critical technical problems for long-term reservoir operation. This coefficient directly determines the storage capacity and the comprehensive benefits of the operation of a coal mine underground reservoir. To this end, the proposed underground reservoir in Daliuta coal mine (No. 22616 working face) is selected in this study for the development and application of an experimental device to measure the storage coefficient. Rock and coal fragments from similar materials are prepared, which are filled and loaded according to the caving rock nature as well as the lumpiness and accumulation mode characteristics pertaining to No. 22616 working face. Subsequently, the measured storage coefficient under circulating water injection conditions revealed a four-dimensional spatial and temporal pattern. It followed the law of storage coefficient under joint interaction of water-rock and stress. The results showed that, prior to the experiment, rock and coal fragments made from similar materials had good water resistance when the paraffin content was set at 8%. The three stress zones were defined based on a theoretical analysis, which were applied on the corresponding loads. During the experiments, significant regional differences were found in the top surface with persisting subsidence of each stress loading zone. Hence, compared with its initial state, the maximum subsidence in the stress stability zone, the stress recovery zone, and the low-stress zone was 7.89, 5.8, and 1.83 mm, respectively. While the storage capacity and the storage coefficient gradually decreased, the former ranged from 0.2429 to 0.2397 m3, and the latter ranged from 0.270 to 0.266. The experimental results are verified by drainage engineering tests in the Shendong Mining Area. In essence, the storage coefficient had remarkable spatial distribution characteristics and a time-varying effect. In space, the storage coefficient increased with height along the vertical direction of the coal mine underground reservoir. However, it decreased with the distance from the boundary of the dam body in the horizontal direction. With time, the storage coefficient decreased dynamically. This study provides a new way of predicting the storage coefficient of a coal mine underground reservoir.
