Developing a new approach to summarize Arabic text automatically using syntactic and semantic analysis
Authors: Alkhudari Amal
Published: February 2021

Due to the wide spread information and the diversity of its sources, there is a need to produce an accurate text summary with the least time and effort. This summary mustÂ  preserve key information content and overall meaning of the original text. Text summarization is one of the most important applications of Natural Language Processing (NLP). The goal of automatic text summarization is to create summaries that are similar to human-created ones. However, in many cases, the readability of created summaries is not satisfactory, Â Â because the summaries do not consider the meaning of the words and do not cover all the semantically relevant aspects of data. In this paper we use syntactic and semantic analysis to propose an automatic system of Arabic texts summarization. This system is capable of understanding the meaning of information and retrieves only the relevant part. The effectiveness and evaluation of the proposed work are demonstrated under EASC corpus using Rouge measure. The generated summaries will be compared against those done by human and precedent researches.Â Â

Published: February 2021

The major cause of concrete structures deterioration is steel corrosion. Consequently, this situation has led researchers to study and test other reinforcement alternatives that are noncorrosive in nature. Rapidly emerging developments in the field of material technology has led to the development of fiber reinforced polymers (FRP). This research focuses on the flexural behavior of carbon, glass, aramid, and basalt (CFRP, GFRP, AFRP, and BFRP) fiber reinforced polymers bars as alternatives to the traditional steel reinforcement in concrete. The study involves a nonlinear numerical finite element analysis of a simply supported reinforced concrete beams subjected to cyclic loading, where the ANSYS program is utilized. The numerical model verification is executed on the experimental beams for ensuring the efficiency of ma-terial models, cyclic loading and various elements. Hysteresis curves are produced for each beam and analyzed, where loads, deflections, and cracks propagation are inspected and discussed. The results reveal that, the full replacement of traditional steel bars with CFRP bars gives the greatest increase in the ultimate load capacity by 38.5%. Also, other results are summarized in this paper.Â

Analysis of power factor corrections for obtaining improved power factors of switching mode power supply
Authors: Stojce Ilcev Dimov
Published: February 2021

This article discusses such an important issue as the power factor of Switching Mode Power Supply (SMPS) and its improvement through Power Factor Correction (PFC). The power factor shows how effectively uses the consumption of electric energy by certain loads connected to the power distribution system with Alternative Current (AC), which is very critical for the electricity-producing industry. The number of power factors is a dimensionless value that can vary from -1 to 1. Thus, in an electric power system, a load with a low power factor draws more current than a load with a high power factor for the same amount of transferring useful power, which may cause overloading of the power grid and lead to over-expenditure of electricity. Otherwise, designing power factor correction (PFC) into modern switched-mode power supplies (SMPS) has evolved over the past few years due to the introduction of many new controller integrated circuits (IC). Today, it is possible to design a variety of PFC circuits with different modes of operation, each with its own set of challenges. As the number of choices has increased, so has the complexity of making the choice and then executing the new design. In this article, the design considerations and details of operation for the most popular approaches are provided.Â Â

Published: February 2021

Rheological properties of lead cement slurry with Mucuna solannie admixture as an extender was measured in accordance with API standard. Bentonite extender was used as a control. The elemental and oxide compositions of Mucuna solannie were determined using Scanning Electron Microscope and X-Ray Florescence (XRF) methods, and rheological properties were obtained using rheometer after conditioning. The rheological data from Mucuna solannie and bentonite lead slurries were validated using Bingham Plastic and Herschel-Bulkley models. The result showed that Mucuna solannie contains high carbon atomic concentration and is responsible for its high rheological properties values. Lead slurry prepared with Mucuna solannie gave higher plastic viscosity, yield point and gel strength than that of bentonite. Herschel-Bulkley model described the rheological properties better than Bingham Plastic model. Due to high rheological properties values of the slurry prepared with Mucuna solannie, dispersant is needed for the optimization of the yield point and gel strength.Â

Authors: Elghazali Elhasan Mohamed , Mohialddin Doush Wael
Published: February 2021

Background: Until recently, the knowledge of the anatomical variations in the relationship between the recurrent laryngeal nerve (RLN) and the inferior thyroid artery (ITA) combined with visual intraoperative RLN identification are essential for the protection of these life-important structures during surgical exposure and the mobilization of thyroid and parathyroid glands. This leads to the proper treatment of patients and improvement of the surgical techniques.Aim: To describe anatomical variations in the relationship of the recurrent laryngeal nerve to the inferior thyroid artery in the Sudanese population.Patients and methods: Following ethical committee approval, an observational descriptive prospective cross-sectional study in the period between March 2019 and February 2020, for anatomical variations in the relation of the recurrent laryngeal nerve to the inferior thyroid artery in seventy-two cervical sides of thirty-six well-dissected embalmed Sudanese cadavers. The RLN was investigated in three positions: posterior to the ITA main trunk, anterior to the ITA main trunk and between the ITA branches. Then, the results were analyzed according to the gender, age and dissection side.Results: We found that the anatomical variations were more frequent in males (97.2%) than females (2.8%). The age of these variations ranged between 31â€“45 years which represents (61.1%). On the right side of the neck, the commonest position of the RLN is posterior to the ITA (63.9%) followed by in decreasing order of frequency, the RLNs run between the ITA branches (30.6%) and anterior to the ITA (5.6%). On the left side of the neck, the commonest position of the RLN is posterior to the ITA (69.4%). It passed between the ITA branches in (30.6%) of specimens. There was no anterior location of the RLN to the ITA. Variations in a relationship of the RLN to the ITA on one side is significantly different from the opposite side.Conclusions: Although the risk of potential damage to the RLN during surgical neck procedures involving the thyroid gland and parathyroid glands is well recognized, pre-operative detailed surgeonâ€™s knowledge for these frequent anatomical variations and the usage of the ITA as an anatomical landmark for intraoperative RLN recognition is important. This will lead to a reduction of iatrogenic RLN injury prevalence. Future studies are recommended to compare the findings on this cadaveric study with a larger sample size in the long-term period.Â Â

Published: February 2021

This paper studies the chiral nonlinear SchrÃ¶dinger equations, describing a central role in the developments of quantum me-chanics, particularly in the field of quantum Hall effect, where chiral excitations are known to appear. More precisely, in this paper, we acquired new exact solutions of the chiral nonlinear (1+1) and (1+2)-dimensional SchrÃ¶dinger equations by using the modified Kudraysov method. As outcomes, some of the new exact traveling wave solutions for the equations above is formally produced. All solutions are plotted in the view of three-dimensional (3D) and two-dimensional (2D) line shape through the MATLAB software for investigating the real significance of the studied equations. The periodic type of solitons is generated by employing modified Kudryashov method which is different from other studied methods.Â

Authors: Bello Rereloluwa , Ajayi Toluwaleke
Published: February 2021

The Vertical Electrical Resistivity surveys in the Sunshine Garden Estate have contributed to a better understanding of the basement complex of Southwestern Nigeria. Nine (9) vertical electrical sounding (VES) using the Schlumberger electrode array were interpreted and the results shows three (3) subsurface geoelectric layers within the study area. These are the weathered layer, topsoil, fresh/fractured basement. Groundwater pockets such as fractured zones, valley fills/basement depressions, and weathered zones were delineated in the study area. Weathered/partially weathered layer and weathered basement/fractured basement were the two major aquifer mapped out and these aquifers are characterized by thick overburden, found within basement depressions. The groundwater potential of the study area was zoned into low, medium and high potentials. Zones where the overburden thickness (which constitutes the main aquifer unit) is greater than 13m and of low clay composition (average resistivity value between 200 - 400â„¦m) are considered zones of high groundwater potential. Area where the thickness of the aquifer ranges from 11-13m with less clay composition are considered to have medium groundwater potential and the areas where the thickness of the aquifer is less than 11m are considered to have a low groundwater. The VES station underlained by high and medium groundwater potential zones are envisaged to be viable for groundwater development within the area.Â Â

Authors: Ahmed Amin Sahar
Published: February 2021

This study is to assesses radioactive materials transported to the beetroot plants grow in different fertilized soil. Equivalent weights of fertilizers were added to the soil prior the plantation. The alpha track densities were estimated utilizing solid state nuclear track detector (SSNTDs), CR-39. The obtained results show that alpha track densities in Beetroot plants in the lower and upper sides of plant leaves were varied from 67.62 Tr.cmâˆ’2 to 101.83 Tr.cmâˆ’2 and from 45.35 Tr.cmâˆ’2 to 94.67 Tr.cmâˆ’2 with mean values of 89.96 Tr.cmâˆ’2 and 68.48 Tr.cmâˆ’2, respectively. Alpha track densities were also measured in the samples of the enhanced plantation soil with fertilizers and in the whole parts of the Beetroot plant which were planted in these soils. These values were compared with alpha track densities obtained from fertilizer samples in the previous studies. The lower face of leaves gives higher Î±-particles activity than that obtained from the upper face. As well as, the alpha activity from the plants planted in soils enhanced with phosphate compost was found greater as contrast with that planted in a soil enhanced with organic fertilizer. The utilization of organic fertilizer don't cause much risks like contrasted with phosphate fertilizers. Therefore, the alpha activity depends on the nature of fertilizers added to the soil.Â Â Â

Magendo: Arbitrage and Ambiguity on an East African Frontier
Authors: Donovan Kevin P.
Published: February 2021

This article examines the ambiguities of arbitrage, focusing on illegal coffee trade across the Uganda-Kenya border. I show how residents of the borderlands harnessed ordinary tools (gunny sacks, tin cans, and gravity scales) and cultural repertoires (kinship, language, and ritual) to cultivate and capitalize on difference. They reworked territorial jurisdiction, measurement standards, and surface appearances in a form of arbitrage known as magendo. While magendo is an ordinary occurrence at the border, I focus on a particular period in which magendo reached spectacular new levels. The resulting binge economy was characterized by competitive gift-giving and interethnic conviviality, but its excessive margins eventually challenged prevailing notions of moral selfhood, gender relations, and the authority of elder men. Seeing arbitrage not merely as the reserve of high finance but also as a strategy of African frontiers provides a way to connect the anthropology of finance to enduring concerns around the postcolonial politics of borders, gerontocracy, and value.

Muhtasari

Nakala hii inachunguza utata wa arbitrage. Maandishi yangu yanazingatia biashara wa kahawa mpakani mwa Kenya na Uganda. Katika nakala hii, ninaonyesha jinsi wakazi wa mipakani walitumia zana za kila siku (magunia, madebe, na mizani) na pia mbinu za kitamaduni (ukoo, lugha, na mila) kuzalisha na kukuza tofauti za kisokoni na faida. Aidha wahusika hawa walipinda na kufinyanga dhana kuhusu udhibiti wa mipaka, desturi za kukadiri, na muonekano wa nje kwa kupitia kitendo cha arbitrage: almaarufu kama magendo. Ingawa uchukuzi magendo si taratibu geni kwa uchumi za mipakani, nakala hii inazingatia wakati ambapo uchuuzi wa kahawa ulifikia kilele cha kustaajabisha na kuleta uchumi wa ukwasi. Kwa upande moja msimu huo ulileta urafiki kati ya jamii tofauti na mienendo kama vile mashindano ya kutunukiana zawadi. Kwa upande mwingine, faida za kiajabu ziliibua miangalio mipya kuhusu maswala ya uadilifubinafsi, jinsia katika jamii, na mamlaka ya wazee. Kuelewa arbitrage kama zaidi ya mazoezi ya kifedha, bali pia kama mkakati wa uchumi za mapembezoni, inatupa njia ya kuunganisha anthropolojia ya fedha na masawali ya mipaka baada ya ukoloni, utawala wa wakongwe, na thamani.

Zasadniczym celem standardów opiniowania psychologicznego w sprawach rodzinnych i opiekuńczych było stworzenie określonego algorytmu pracy ekspertów z zakresu psychologii sądowej, który ma stanowić pomoc w jak najlepszym wywiązywaniu się z powierzonych im zadań. Jednocześnie dokument może służyć ocenie poprawności opinii ich odbiorcom, którymi są zarówno zleceniodawcy (sądy), jak i opiniowani oraz reprezentanci ich interesów w postępowaniu przed sądem (np. adwokaci). W artykule opisano historię powstawania standardów, osoby zaangażowane w ten proces oraz jego efekty. Przedstawione zostały także założenia teoretyczne oraz sposób rozstrzygnięcia dylematów, które pojawiały się na poszczególnych etapach powstawania tekstu.
Application of multivariate regression on magnetic data to determine further drilling site for iron exploration

Published: February 2021

In this study, a new approach of the multivariate regression model has been applied to make a precise mathematical model to determine further drilling for the detailed iron exploration in the Koohbaba area, Northwest of Iran. Furthermore, to figure out the additional drilling locations, the ore length to the total core ratio for the drilled boreholes has been used based on the geophysical exploration dataset. Hence, different regression analyses including linear, cubic, and quadratic models have been applied. In this study, the ore length to the total core ratio of the chosen drilled boreholes has been considered as a dependent variable; besides, the outputs of the magnetic data using the UP10 (10m upward-continuation), RTP (reduction to the pole), and A.S. (analytic signal) techniques have been designated as independent variables. Based on probability value (p-value), coefficients of determination (R

), and efficiency formula (EF), the fourth regression model has revealed the best results. The accuracy of the model has been confirmed by the defined ratio of boreholes and demonstrated by four additional drilled boreholes in the study area. Therefore, the results of the regression analysis are reasonable and can be used to determine the additional drilling for the detailed exploration.
Influence of the Material State of Ground, Case-Hardened Steels on the Barkhausen Noise Depending on the Surface Integrity*
Authors: Sackmann D. , Heinzel J. , Karpuschewski B.
Published: February 2021

The manufacturing process of grinding generally leads to a thermo-mechanical influence on the surface integrity. In addition to the intended development of residual compressive stresses due to the finishing process, disturbances in the grinding process can lead to negative effects such as tensile residual stresses, tempering and even rehardening zones and significantly reduce the component lifetime. In industrial applications, the analysis of Barkhausen noise is becoming increasingly important for the detection of this unwanted thermo-mechanically influenced surface integrity. The non-destructive method reacts sensitively to changes in, for example, the residual stress state as well as the hardness. In addition, other material-, process- and metrology-related influences are described in literature. The investigations presented in this paper deal with the influence of different material states (case-hardening depth, surface carbon content and alloy composition) on the signals of the Barkhausen noise as a function of the surface integrity. It is shown that the signal level is significantly influenced by the material condition and thus individual limit values must be used for evaluation of the surface integrity. ◼
Suitable Material Selection for Large Size Cylindrical Gears*

Published: February 2021

Globalization and international supply chains constantly challenge gear- and steel manufacturers. In the case of large gear units in particular, expensive alloy contents have a direct impact on the material price. Steels with lower alloy contents and therefore cheaper steels are therefore becoming the focus of attention in order to further improve competitiveness. This article therefore compares two materials with different alloying elements and contents and thus different hardenability behaviour. For this purpose, extensive material characterizations as well as pulsator tests were carried out on case-hardened large gears. The aim of these tests was to determine the tooth root load-bearing capacity of the two material variants. Finally, the results are compared, discussed and recommendations for industrial application are derived, taking into account the hardenability of large gears. ◼
Plasma Nitriding Mechanisms of Low-Density Sintered Metal Products
Authors: Roliński E. , Woods M.
Published: February 2021

The mechanism of plasma nitriding include the formation of various active species generating nitrogen atoms reacting with the metal. Which species prevail in supplying nitrogen depends on nitriding conditions as well as the nature of the treated metal. Plasma nitriding of low-density powder metal (PM) products results in a formation of the layers whose thicknesses may depend on the gas pressure used for the process. Higher pressure can cause locally deeper penetration of the surface by active nitrogen species formed from ammonia compounds generated by the plasma. While a low processing pressure reduces this effect significantly. The formation mechanism of a locally thicker layer relies on the presence of open porosities in the surface as they can be penetrated by the ammonia species generated by the plasma. The same porosities cannot be penetrated by the ions of nitrogen formed at the same time since their mean free life is much shorter than that of ammonia species. ◼

Published: February 2021

Aiming at the current development of drilling technology and the deepening of oil and gas exploration, we focus on better studying the nonlinear dynamic characteristics of the drill string under complex working conditions and knowing the real movement of the drill string during drilling. This paper firstly combines the actual situation of the well to establish the dynamic model of the horizontal drill string, and analyzes the dynamic characteristics, giving the expression of the force of each part of the model. Secondly, it introduces the piecewise constant method (simply known as PT method), and gives the solution equation. Then according to the basic parameters, the axial vibration displacement and vibration velocity at the test points are solved by the PT method and the Runge–Kutta method, respectively, and the phase diagram, the Poincare map, and the spectrogram are obtained. The results obtained by the two methods are compared and analyzed. Finally, the relevant experimental tests are carried out. It shows that the results of the dynamic model of the horizontal drill string are basically consistent with the results obtained by the actual test, which verifies the validity of the dynamic model and the correctness of the calculated results. When solving the drill string nonlinear dynamics, the results of the PT method is closer to the theoretical solution than that of the Runge–Kutta method with the same order and time step. And the PT method is better than the Runge–Kutta method with the same order in smoothness and continuity in solving the drill string nonlinear dynamics.
Fractional Kirchhoff-type problems with exponential growth without the Ambrosetti–Rabinowitz condition
Authors: Pei Ruichang
Published: February 2021

The main aim of this paper is to investigate the existence of nontrivial solutions for a class of fractional Kirchhoff-type problems with right-hand side nonlinearity which is subcritical or critical exponential growth (subcritical polynomial growth) at infinity. However, it need not satisfy the Ambrosetti–Rabinowitz (AR) condition. Some existence results of nontrivial solutions are established via Mountain Pass Theorem combined with the fractional Moser–Trudinger inequality.
On the acquisition of potential verbs and conjugation types of verbs in Japanese
Authors: Takahashi Hideya
Published: February 2021

It is well-known that children whose native language is Japanese first begin vocalizing potential verbs at about the age of 2 years and continue to utter ungrammatical forms which are not used in adults’ speech as well as correct ones until approximately at the age of 5 years when their acquisition of potential verbs completes, with virtually no erroneous uses observed. Interestingly enough, the process of the acquisition of potential verbs proceeds in a manner parallel with that of causative/inchoative alternation. In this study, based on children’s natural speech data reported in previous research, we argue that the approach put forth in Fuji, Hashimoto, and Murasugi (2008a. “A VP-shell analysis for the undergeneration and the overgeneration in the acquisition of Japanese causatives and potentials.” Nanzan Linguistics 4: 21–41; 2008b. “VP-shell analysis for the acquisition of Japanese potentials.” Nanzan Linguistics: Special Issue 3(2): 65–102) is not empirically valid in that it cannot correctly predict changes in morphological patterns of potential verbs uttered by children along the period of language acquisition. Moreover, in the course of our discussion, it is shown that the acquisition process of the potential morpheme e by children can be identified as that of (in)transitive morpheme e which forms the class of mono-grade vowel-ending verbs.

Concentration solar power (CSP) systems convert solar radiation to heat and use heat engines to convert the heat to electricity. The solar receiver over which the solar radiation is concentrated and converted to heat is the most important part of the CSP. To attain maximum efficiency, the receiver in the CSP systems needs to be coated with an efficient selective solar absorber coating. In recent years, a lot of research has been focused on solar selective coatings. This has resulted in the synthesis of novel coatings that have high thermal and chemical stability, long term durability, and excellent solar selectivity making them suitable for solar thermal applications. This report reviews various solar selective coatings based on transition metals and their compounds. Various failure mechanisms are discussed in detail along with suggested prevention methods. Several thermal stability and durability tests are reported with their benefits and limitations. The effect of long-term durability on the levelized cost of coating is also discussed. Finally, we list some excellent systems and explore different ways of improving the thermal stability for SSCs, thus providing a reference for the design and optimization of new SSCs.
