Authors: Zhou Chao , Sun Chuanheng , Lin Kai , Xu Daming , Guo Qiang , Chen Lan , Yang Xinting 
Published: April 2018

Abstract. In aquaculture, almost all images collected of an aquaculture scene contain reflections, which often affect the results and accuracy of machine vision. Classifying these images and obtaining images of interest are key to subsequent image processing. The purpose of this study was to identify useful images and remove images that had a substantial effect on the results of image processing for computer vision in aquaculture. In this study, a method for classification of reflective frames based on image texture and a support vector machine (SVM) was proposed for an actual aquaculture site. Objectives of this study were to: (1) develop an algorithm to improve the speed of the method and to ensure that the method has a high classification accuracy, (2) design an algorithm to improve the intelligence and adaptability of the classification, and (3) demonstrate the performance of the method. The results show that the average classification accuracy, false positive rate, and false negative rate for two types of reflective frames (type I and II) were 96.34%, 4.65%, and 2.23%, respectively. In addition, the running time was very low (1.25 s). This strategy also displayed considerable adaptability and could be used to obtain useful images or remove images that have substantial effects on the accuracy of image processing results, thereby improving the applicability of computer vision in aquaculture. Keywords: Aquaculture, Genetic algorithm, Gray level-gradient co-occurrence matrix, Principal component analysis, Reflection frame, Support vector machine.

Authors: Harmon Joshua D. , Luck Brian D. , Shinners Kevin J. , Anex Robert P. , Drewry Jessica L. 
Published: April 2018

Abstract. Forage harvest is a time and energy intensive process requiring the coordination of multiple pieces of equipment. Detailed characterizations of the time spent in each work state for each piece of equipment would increase the understanding of process inefficiencies and aid in development of optimization tools. Geospatial and controller area network (CAN) machine data were recorded on forage harvesters and transport equipment, during two types of harvest operations, to quantify utilization of harvesters and transports as well as transport productivity. The data collection and processing method was successful in identifying work states for forage harvesters and transports. The results indicated that overall utilization of the harvester for harvesting was 61% and dependent on transport availability. The portion of total operational time spent in the idle work state (idle utilization) was 10% to 20% for transports and 18% to 23% for harvesters. A new metric for transport productivity was developed and found to be highly dependent on transport capacity ranging from 125 to 49 Mg km h-1 for semi-trucks and smaller transports, respectively. The proposed data collection methods and productivity metrics could be used to optimize the forage harvest process to reduce idle time and maintain crop quality. Keywords: Controller area network, Cycle analysis, Forage harvester, Global positioning system.

Published: April 2018

Abstract
In this study, we investigate the production of hypolipidemic agents in the form of Acipimox sustained-release tablets, using a wet pelleting process. The purpose of this research is to reduce the total intake time for patients and to lower the initial dose in such that the adverse reactions could be reduced. This study adopts the single-factor method and orthogonal experiments by using hydroxypropyl methyl cellulose (HPMC K15M) as the main sustained-release prescription composition. The final prescription is Acipimox 20%, HPMC K15M 26.67%, sodium carboxymethyl cellulose 30%, polyethylene glycol (PEG 6000) 1%, ethyl cellulose 16.6%, lactose 4.67% and magnesium stearate 1%. The dissolution of tablets reached 85.88% in 8 h. The difference in the weight, hardness and friability of the tables met the requirements in the Chinese Pharmacopoeia; to test the stability, a temperature and illumination accelerated test method was used, the results indicate that the Acipimox sustained-release tablets should be sealed and stored in a dark, cool area. A preliminary study on the tablets’ releasing mechanism showed that their release curve fitted the Higuchi model (the formula is Mt
/M
∞ = 31.137 t1/2–3.605 (R
2 = 0.9903)). The Acipimox tablets’ release principle is dominated by the diffusion mechanism.
Exports and Financing Constraints Evidence from Turkey
Authors: Gezici Armağan , Orhangazi Özgür , Yalçın Cihan 
Published: April 2018

AbstractThis paper examines the link between financing constraints and firm exporting behavior through an in-depth study of the Turkish manufacturing firms between 1996 and 2013. Utilizing a rich firm-level data set, we test for bothex-anteandex-postlinks between exports and financing constraints to tackle potential selection biases and endogeneity problems. We find a positive and statistically significant export premium for financing constraints in general. In further testing we show that there is no significant evidence of pre-entry premium, while we find that financing constraints faced by exporting firms are eased once they start exporting, confirming an improvement in the financial conditions of export starters compared to non-exporters.
On locally compact semitopological O-bisimple inverse ω-semigroups
Authors: Gutik Oleg 
Published: April 2018

Abstract
We describe the structure of Hausdorff locally compact semitopological O-bisimple inverse ω- semigroups with compact maximal subgroups. In particular, we show that a Hausdorff locally compact semitopological O-bisimple inverse ω-semigroup with a compact maximal subgroup is either compact or it is a topological sum of its H-classes. We describe the structure of Hausdorff locally compact semitopological O-bisimple inverse ω-semigroups with a monothetic maximal subgroups. We show the following dichotomy: a T1 locally compact semitopological Reilly semigroup (B(Z+, θ)0, τ) over the additive group of integers Z+, with adjoined zero and with a non-annihilating homomorphism is either compact or discrete. At the end we establish some properties of the remainder of the closure of the discrete Reilly semigroup B(Z+, θ) in a semitopological semigroup.
Improvement of Tribology in Sheet Metal Forming of High-Strength Steel Sheets by PVD-Coated Dies
Authors: Sivarajan S. , Padmanabhan R. 
Published: April 2018

Abstract
During sheet metal formation, the high strength of sheet material leads to high contact stress between the die and blank material, which results in increased die wear. Moreover, the reduction in the use of lubricants because of environmental concerns has led to greater wear of sheet metal–forming dies. It is important to understand the tribological behavior of the blank die contact so that steps can be taken to reduce the die wear to an acceptable level. Die wear reduction is possible by using alternative die materials, modifying die geometry, or by creating a wear-resistant surface on sheet metal–forming dies using Physical Vapor Deposition (PVD) coatings. PVD coatings have a thickness in the micro range and greatly improve the tribological properties of the die material. In this work, three pins made of AISI D2 steel were coated with Titanium Nitride, Titanium Aluminum Nitride (TiAlN), and Aluminum Chromium Nitride using the PVD process. Friction and wear tests were conducted on the pin-on-disk testing machine as per ASTM G99, Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus. The pins had diameters measuring 10 mm and lengths measuring 35 mm. They were heat treated until they reached 55 HRC and ground to a Ra value of 0.1 µm. A 5-mm-radius tip was provided on one end of the pin. D3 steel was used as counter material (disk). The normal load was 30 N, and the sliding speed was 0.3 m/s. The experiments were conducted in dry contact conditions. Based on the results, it was concluded that TiAlN coatings are an excellent choice to modify friction behavior and improve wear resistance of die material.
ASTM E08.07.09 Analytical Round-Robin on the Use of DC Electrical Potential Difference for the Measurement of Crack Size in Ductile Fracture Testing
Authors: Lucon E. 
Published: April 2018

Abstract
The Direct Current Electrical Potential Difference (DCEPD) technique has been used for many years in fatigue and fracture testing for monitoring crack propagation in metallic materials. The principle of DCEPD methods is that when a constant current flows through a cracked specimen, the voltage change measured across the crack plane can be analytically related, empirically related, or both, to the change in crack size. In fatigue testing, performed within the limits of Linear Elastic Fracture Mechanics, crack propagation is the sole source of potential change. In ductile fracture testing, additional contributions from specimen dimension changes and crack-tip plastic deformation (blunting) have to be accounted for and distinguished from the DCEPD increase caused by crack growth. The ASTM E08.07.09 Task Group, formed in 2013 and chaired by the author, has been developing an annex for ASTM E1820, Standard Test Method for Measurement of Fracture Toughness, which focuses on the use of DCEPD measurements for the prediction of crack size and crack extension in ductile fracture toughness tests. This article presents the analysis of an analytical round-robin, in which 8 participants analyzed 24 existing fracture toughness data sets using two different approaches, based on the analysis of the displacement versus DCEPD and force versus DCEPD, respectively. The comparison between these two approaches and the implications for the ASTM E1820 annex being developed are the focus of this article.
Guidance in Mass Media – Analysis of the Selected Examples
Authors: Dąbrowska-Cendrowska Olga 
Published: April 2018

Guidance in media is not a new phenomenon. Looking for the answers to more or less complex questions about human existence seems to be as old as human society. A great deal of books are guidance books. Guidance has always been present in the press. Guidance programmes are also found on television. The Internet is dominated by the communication guidance based on one to one or/and one to few principles. However, the popularity of some websites, portals and blogs makes this way of communication similar to the traditional, periodical mass media (one-to-many).Contemporary media, and to be more precise, media offer has become a commodity. In order to be sold, it undergoes the processes of tabloidisation. Due to this, the owners can count on higher profits as the product reaches a larger audience. Guidance in press and on television has become one of the ways to make money.The article is based on the offer addressed to the female mass audience and is an attempt to answer the questions: what are the characteristics of mass guidance, what subject matter dominates in the popular media offer addressed to the mass audience, and what benefits does the sender get from the message?
How to Study the Language Norm Scientifically – Preliminary Issues
Authors: Zbróg Piotr 
Published: April 2018

The article presents an attempt at solving chosen problems related to the preparation to conduct a scientific research of a language norm. Until now, linguists have not attempted at describing the language norm according to its definition. It should be viewed as a social phenomenon. Its research ought to be conducted by the means of mixed methods, including methods inherent to linguistics and social sciences. A proper representative group of contemporary users of the Polish language should be chosen according to the rules applied to regular opinion polls. The questionnaire tools, allowing the creation of situations similar to the natural reaction to correct and incorrect forms, are necessary. In order to evaluate the level of the norm (e.g. model forms, correct forms, acceptable forms), it is necessary to determine the way of interpretation of the obtained results (e.g. more than 85% of positive results qualifies the variant to the model forms, less than 65% – to forms outside the norm). In this way, a reliable image of contemporary language norm would be obtained and a rational basis for the development of the codified norm would be created. There is a high social demand for a reliable source of the way in which Polish should be written and spoken. The constant updating of the normative publications is also necessary, hence the requirement to make them available online. The monitoring of changes of the habit and noting them are equally important.
Lexical Limits and Fringes in Medical Terminology
Authors: Briaukienė Birutė 
Published: April 2018

The article analyses the attitudes of the students of Lithuanian University of Health Sciences (LSMU) regarding the use of loanwords in medical terminology. Many of the previously unacceptable and avoidable barbarisms used in the book of language tips “Lexicology: usage of loanwords” (published in 2013), became standard versions of the general language. Among such loanwords are the medical terms, which led to carrying out this research. Survey respondents were second-year students of the Faculty of Medicine of LSMU. The study involved 100 students. A list of 40 medical terms was specifically made for this research and was submitted to the students. The aim of this article is to research whether students are able to determine the ratio of a loanword to the norm of the standard language. The article raises the hypothesis that the students will be able to differentiate normative and non-standard loanwords. The analysis showed that 85.8% of respondents indicated loanwords being totally unacceptable and avoidable. Twice as many respondents reported that the loanwords, considered as side version of the norm, did not meet the requirements of the standard language norm. More than half (56.5%) of respondents indicated that loanwords, considered as an equivalent variant of the norm, did not meet the requirements of the standard language norm. The research hypothesis proved to be true.
Inflexional Variants of the Type ‘Bagaży // Bagażów’ in the Contemporary Polish Language
Authors: Ruszkowski Marek 
Published: April 2018

This article describes variants of the plural genitive of masculine nouns with variant endings – ów//-y (more seldom -i). Personal nouns are syncretic with accusative forms, i.e. czarodziei // czarodziejów; kuracjuszy // kuracjuszów; przybyszy // przybyszów. 40 pairs of variants of the type krokodyli // krokodylów were analysed. They were verified in terms of linguistic norm and frequency. The first verification was based on the determinations made in The Great Dictionary of Correct Polish Usage (GDCPU) published by PWN (in Polish: Wielki słownik poprawnej polszczyzny PWN), while the second one was based on The National Corpus of the Polish Language available in an electronic form.Out of 40 pairs of nouns, only 9 pairs have the ending -ów , which accounts for 22.5%. These are personal nouns (cywilów, czarodziejów, pedofilów, przybyszów, uczniów) and inanimate impersonal nouns (napojów, rodzajów, słojów, zwojów). Some of them are more frequent, as they are: 1. the only correct forms (pedofilów, zwojów); 2. non-colloquial, meaning they are recommended to be used in a carefully spoken and written Polish language (rodzajów, uczniów; colloquially rodzai, uczni); 3. non-jargonistic (cywilów; jargonistic – cywili); 4. regarded as seldom (przybyszy). Out of 8 pairs of forms treated by GDCPU as totally variant, only 3 pairs have the ending -ów (czarodziejów, napojów, słojów). The frequency of two first pairs is more than 90%, while the frequency of the form słoi is 77%. The share of napoi is only 3.6%, although it is also a form of a verb napoić (i.e. On napoi konie). It may seem that a scope of variants of the analysed forms is large. However, a considerable part of doublets are forms that are considered seldom, archaic, colloquial, jargonistic or inconsistent with the language norm. Thus, the thesis of a substantial variant occurrence of such types of forms should be verified.
The Structure of Drymonims in Radviliškis District
Authors: Mickienė Ilona , Bieliauskaitė Rimantė 
Published: April 2018

This article analyses the drymonyms from the “Lithuanian Forests Name Book”, Lithuanian Geoinformation Data Base and Radviliškis district map (200). Drymonyms are a constantly changing part of the Lithuanian landscape, and it is imperative to fix and research them periodically. Drymonyms in Radviliškis district have not been researched in any way. The classification of Radviliškis district drymonyms, classifying primary and secondary drymonyms first, is based on grammatical-structural classification scheme of Aleksandras Vanagas. Secondly, drymonyms with suffixes or inflections were selected as well as mixed structure drymonyms, compound and composite drymonyms. The research demonstrated that the majority of Radviliškis district drymonyms were identified as secondary names (88.5%), whereas the number of primarily names was significantly lower (11.5%). The analysis of Radviliškis district drymonyms will be useful for further research of this region’s toponym classification. Investigation of the drymonyms and understanding of their common word-building tendencies could lead to further research of extralinguistic aspects (social, economic and psycholinguistic) of the region’s toponyms.
“Assessment in Dialogue” (AID). Assessing the Communicative Action
Authors: Piasta-Siechowicz Joanna 
Published: April 2018

“Assessment in Dialogue” (AID) is a model of Joanna Piasta-Siechowicz addressed to the participants of general education: students-teachers-parents. AID reconciles contradictory tendencies of the philosophy and praxis of student assessment: the pursuit of objectivity of the former and the need of individualisation of the latter. It aspires to combine the objectivity of requirements and evaluation criteria with the need of individualisation. It is also well suited to help teachers in systematic planning of their work. “Assessment in Dialogue” refers to the trisubjectivity (student-parent-teacher) in the planning and organisation of student’s activities and, as a result, in informing about his/her achievements during a lesson. Implemented in a primary school since 2012, “Assessment in Dialogue” is popularised at conferences of principals and teachers in Poland and Ireland, workshops for teachers, publications in methodical journals. It is grounded in the official documents of the Ministry of National Education, European Council recommendations and conclusions from ten years of constant evaluation of the psycho-didactic process in schools as well as the functioning of evaluation system in Poland.
The Rhetoric of Travel: Persuasion Tools in the Lithuanian Travel Literature
Authors: Gibavičienė Gabrielė 
Published: April 2018

Rhetoric which in the context of this research is seen not only as a structure of text but also as a structure of thought is presented in the article as a new universal way of researching Lithuanian travel literature discourse. Three popular Lithuanian travel books are chosen for this research – Kelionė į Jeruzalę (Journey to Jerusalem, 1601) by Mikalojus Kristupas Radvila Našlaitėlis, Svečiuose pas 40 tautų (At the Company of 40 Nations, 1935–1936) by Matas Šalčius, and Sapnuoju, kad einu (Dreaming the Path, 2014) by Jokūbas Vilius Tūras. The article presents the research of three persuasion tools ethos, logos and pathos in Lithuanian travel literature and how they are involved in successful communication process. The article reveals exactly how trusting the author and presenting actual traveller’s experience is connected with stimulating audience’s emotions and what part in this process is taken by the journey itself. The article also analyses how the enthymeme is involved in achieving persuasion and how it captures traveller’s views, communication guidelines and common features of different travel texts.
