Opis:
The field programmable gate array (FPGA) is used to build an artificial neural network in hardware. Architecture for a digital system is devised to execute a feed-forward multilayer neural network. ANN and CNN are very commonly used architectures. Verilog is utilized to describe the designed architecture. For the computation of certain tasks, a neural network’s distributed architecture structure makes it potentially efficient. The same features make neural nets suitable for application in VLSI technology. For the hardware of a neural network, a single neuron must be effectively implemented (NN). Reprogrammable computer systems based on FPGAs are useful for hardware implementations of neural networks.

Opis:
Currently, in many countries with the coal mining industry, the technology of using artificial pillars has been successfully applied to replace coal pillars to protect the entry gate road, thereby reducing the rate of resource loss, as well as the cost of entry gate road, and mining costs. However, in order to optimize the required width and compressive strength of artificial pillars with thickness, slope angle and mining depth, more detailed studies are required for each specific geological condition. This research uses Phase 2 numerical simulation software to analyze the stability of artificial protective pillar of the roadway prepared in the mining of medium-thick coal seams in the Quang Ninh coal region (Vietnam). The research results show that the relationship between the width of the artificial pillar and the slope angle follows the rule of a linear function. The size of the artificial protection pillar increases according to the mining depth. When the mining depth is 350m, the size of the pillar changes from 1.0 ÷ 2.4m, and to 1.4 ÷ 2, 8m at a depth of 500m. When the slope angle increases, the required pillar width also increases. That is due to the fact that at a large slope angle, the pressure acting on the pillar is not at the center, but deflects to the side adjacent to the entry gate road that needs to be protected, the compression force is not distributed evenly. The required compressive strength of the artificial pillar varies according to the condition of the slope angle, when the seam slopes 10°, the required compressive strength is from 8 to 12 MPa, when the slope angle increases to 20°, the required compressive strength of the pier increases to 18 ÷ 28 Mpa, but when the slope angle increases to 35°, the required compressive strength of the pillar tends to decrease to 16 ÷ 17 MPa. Thus, when operating in the corresponding conditions, it is necessary to choose the size and required compressive strength of the artificial pillar to ensure the working capacity of the pillar.

Opis:
This article explores the meanings attached to individual narrative elements of the tales that portray the laudable deed of Godfrey in the Bridge Gate battle (March 6, 1098). The comparative method offers deeper insight into the elaborate stories that chroniclers have told about Godfrey, who hewed in half his formidable opponent with a single blow on the bridge near beleaguered Antioch. Judging by the diversity of narratives concerning Godfrey’s deed in the Bridge Gate battle, the chroniclers sought to place this confrontation in a special dimension and to portray it as a breakthrough moment. This exaltation was also pivotal to characterizing Godfrey, who became the first ruler of the Crusaders’ kingdom after the conquest of Jerusalem.
Celem artykułu jest odkrycie znaczeń i sensów wiązanych z poszczególnymi elementami narracyjnymi opowiadań o chwalebnym czynie Gotfryda w bitwie pod Bramą Mostową (6 marca 1098 r.). Poprzez wykorzystanie metody komparatystycznej staram się głębiej zrozumieć rozbudowane opowieści kronikarskie na temat Gotfryda, który jednym ciosem przepołowił ogromnego przeciwnika na moście pod obleganą Antiochią. Bogactwo opisów czynu Gotfryda w bitwie pod Brama Mostową wskazuje, że kronikarze dążyli do nadania temu starciu szczególnego wymiaru i pokazania go jako momentu przełomowego. Był to również kluczowy element charakterystyki Gotfryda, który po zdobyciu Jerozolimy został pierwszym władcą krucjatowego królestwa.

Opis:
This work present an efficient hardware architecture of Support Vector Machine (SVM) for the classification of Hyperspectral remotely sensed data using High Level Synthesis (HLS) method. The high classification time and power consumption in traditional classification of remotely sensed data is the main motivation for this work. Therefore presented work helps to classify the remotely sensed data in real-time and to take immediate action during the natural disaster. An embedded based SVM is designed and implemented on Zynq SoC for classification of hyperspectral images. The data set of remotely sensed data are tested on different platforms and the performance is compared with existing works. Novelty in our proposed work is extend the HLS based FPGA implantation to the onboard classification system in remote sensing. The experimental results for selected data set from different class shows that our architecture on Zynq 7000 implementation generates a delay of 11.26 μs and power consumption of 1.7 Watts, which is extremely better as compared to other Field Programmable Gate Array (FPGA) implementation using Hardware description Language (HDL) and Central Processing Unit (CPU) implementation.

Opis:
In order to achieve higher frequency measurement accuracy, this paper proposed a characteristic pulse detection method of fuzzy area based on the quantized phase processing method of different frequency groups. First, the fuzzy area of the group phase coincidence points continuously moved on the time axis after passing through delay elements. The moving distance, that is, the number of the delay elements was determined by the main clock cycle of the D flip-flop. After that, three groups of phase coincidence detection fuzzy areas in different positions were sent to the digital logic module to extract the edge pulses of the phase coincidence detection fuzzy area. The pulse width is determined by the difference between the clock cycles of the delay elements. The clock cycles of different delay units were adjusted to obtain nanosecond or even picosecond circuit detection resolution. Finally, the pulses generated at the edge of the phase coincidence fuzzy area are taken as the switching signal of the frequency signal counter, so the stability of the gate signal and the accuracy of the gate time measurement are improved. The experimental results show that frequency stability can reach the order of E–13/s. In addition, compared with the traditional measurement method, it is characterized by simple structure, low cost, low noises, and high measurement resolution.

The objective of this contribution is to contrastively analyze the currency of words formed by the frac- tolexeme -gate in French and Czech languages. Before presenting the results of our research that relies especially on data derived from the SketchEngine (Czech Web 2017; French Web 2017) corpora, we find it necessary to address theoretical questions to frame the concept of fractocomposition in current linguistic studies. We have borrowed the term fractocomposition from the French linguist Jean-François Sablay- rolles (2019, p. 149), who defines it as a case of compounds “one of whose elements is a fractolexeme,   a fragment of lexie which is valid for the entire lexie”. However, in our discussion we note also other terms that are also used to denote the same concept.

W artykule przedstawiono wyniki numerycznej prognozy działania klapowego regulatora stanów wody w rowie nawadniającym. Obliczenia numeryczne wykonano przy zmiennych wartościach dopływu wody do rowu oraz oporów przepływu w rowie charakteryzowanych współczynnikiem szorstkości Manninga. Sformułowano ogólne relacje pomiędzy czasem otwarcia klapy regulatora a wielkością natężenia przepływu w rowie i oporami przepływu. Wyznaczono wartość natężenia dopływu wody do rowu nawadniającego, przy której klapa regulatora pozostaje cały czas uchylona.
This paper presents the results of a numerical prediction of the performance of a circular flap gate upstream water level regulator in an irrigation ditch. Numerical calculations were performed assuming variable values of the volumetric flow rate. In order to take into account the channel resistance, the Manning roughness coefficient was used. General relations between the opening time of the regulator flap and the flow rate and channel resistance were formulated. The value of a flow rate in the irrigation canal was determined, at which the regulator flap remains open.

Opis:
The article presents the experimental results of the calibration of the typical check structure with sluice gates installed in a trapezoidal irrigation channel. Hydraulic experiments on sluice gate discharge capacity were performed on a model made in a 1:2 scale. It has been explained how the method of measuring the downstream water depth below the sluice gate in the check structures installed in a trapezoidal irrigation channels affects the measured depth values. On the basis of hydraulic measurements, regression relationships were developed for the discharge coefficients for submerged outflow through the sluice gate in two types of sluice gates installed in irrigation channels. The formulas allow to calculate the volumetric flow rate below the submerged sluice gate after determining the water depth upstream and below the sluice gate and the gate opening height. The differences in volumetric flow rates calculated from regression relationships and measured values do not exceed 10%, which confirms their practical suitability for calculating the discharge through a sluice gate mounted in a trapezoidal channel. The values of the discharge coefficients determined in the channels with rectangular cross-sections are not useful for the discharge coefficients of sluice gates check structures installed in trapezoidal channels. Nomograms and relationships for discharge coefficients of the analysed sluice gate were developed.

Breast cancer remains one of the major causes of mortality among female cancer patients. This fact caused a spark in the medical field, which in turn helped to improve the diagnostic and treatment of breast cancer patients over the years making this field always active with new ideas and innovative methods. In our study, a new method was explored using an energy-resolving detection system made from a NaI (Tl) scintillation detector to detect the gamma photons from an Am-241 radiation source to try and construct an image by scanning the American College of Radiology (ACR) mammography phantom. In addition to the experimental work, a Geant4 Application for Tomographic Emission (GATE) toolkit was used to investigate more complex options to improve the image quality of mammographic systems, which is limited by the experimental setup. From the experimental setup, the researchers were able to construct an image using the 26.3 keV and the 59.5 keV energy photons, to show the largest size tumour (12 mm) in the ACR phantom. With an improved setup in the simulation environment, the majority of the ACR phantom tumours was visible using both energy windows from the 26.3 keV and the 59.5 keV, where the 26.3 keV yielded better quality images showing four tumours compared to three when using 59.5 keV. The simulation results were promising; however, several improvements need to be incorporated into the experimental work so that the system can generate high-resolution mammographic images similar to the ones obtained by the GATE simulation setup.

This article follows a study undertaken 2017 in the journal Colloquia Theologica Ottoniana (pp. 57–67). The argumentation proposed at that time justifying the reading of the term πύλαι in Mt 16,18 as “throats” is here enriched with two other reasons for just such understanding of the analyzed Greek noun. The recited evidence comes from Sophocles’ Antigone and in some measure confirms the correctness of the proposed interpretation.

Zaproponowana wówczas argumentacja, uzasadniająca odczytanie słowa πύλαι w Mt 16,18 jako „gardziele”, jest tu wzbogacona o kolejne dwie racje przemawiające za takim właśnie zrozumieniem analizowanego greckiego rzeczownika. Przytaczane dowody pochodzą z Antygony Sofoklesa i niejako utwierdzają w słuszności proponowanej interpretacji.

Opis:
This study aims to supplement the literature on the factors affecting wheat producer productivity and profitability by focusing on the role of governance structures and asymmetric information – an issue that is rarely discussed in developing countries. The study thoroughly explores the effect of governance structures and asymmetric information to model a hypothesis for Ethiopia. The study area enables an exemplary case study as it is one of the top wheat-producing areas in both Ethiopia and all of Africa. The study area has also been registered as a wheat belt region in Sub-Saharan Africa. This study used personal interviews to collect primary data from actors. Mixed sampling techniques (i.e., random, census, and purposive) were used to select sampling units. Multiple linear regression models were used to analyse the data. The results show that governance structures, Farm-gate transactions, and asymmetric information have a significant effect on wheat productivity and profitability. Asymmetric information significantly reduces the profit and yield of wheat producers. The study implies that the government should apply a policy related to institutional arrangements to enhance productivity and profitability in wheat supply chains.
