SOME FEATURES OF MILLS OPERATION COLD PILER PIPE ROLLING
Authors: Rakhmanov S.R.
Published: September 2019

Purpose. The establishment of the essence of many
dynamic phenomena and the prediction of peak loads,
both during the design or reconstruction stages of HPT
mills and their operation using advanced calculation
methods remain relevant.
Methodology. An engineering technique to simplify
a developed dynamic model is proposed, which includes
the combination and development of known techniques.
In addition, active mechanical connections in the original
dynamic model of an HPT mill are identified, causing the
pronounced parametric processes in the system under
study.
Findings. The study of the dynamics of simplified two-mass models of the HPT mill with combined parameters
and periodically changing mass characteristics has been
carried out. A differential equation of parametric oscillations
in the drive power line has been compiled. The solution to
the differential equation allows us to estimate the dynamic
displacements of the considered drive of the working stand
of the HPT mill for the most common modes of vibration
of the mechanical system. Since the differential equations
(8) are present in the formulation of the basic Cauchy
problem, we implement the solution numerically, using the
Runge - Kut method in the medium of a standard software
product, for the most common first form of oscillations of
a mechanical system.
Originality. Dynamic features of the operation of the
drive of the working stand of the HPT mill are presented
in the form of angular displacements of the drive shaft of
the mechanical system. The dynamics of the drive drive
of the working stand of the HPT, 32-3 mill are calculated
(pipe rolling along the route 38×3.8 → 19.1×2.1, material –
steel Х18Н10Т).
Practical value. The causes of the appearance of
parametric oscillations in the drive system are identified
and dynamic instability zones of the mechanical drive
system of the HPT mill is installed, which allows for the
selection of optimal rolling conditions at the design stage
of technological processes.
Keywords: cold rolling, pipe, mill, power line,
main drive, dynamic model, simplified design scheme,
mathematical model, parametric oscillations, differential
equation, angular oscillations, dynamic instability.
Tvíræða orðasambandið að ósekju
Authors: Þórhallsdóttir Guðrún
Published: September 2019

This paper discusses the origin and history of the Icelandic phrase að ósekju (OIcel. ‘with impunity’, ModIcel. ‘without guilt, without cause’). Most handbooks have interpreted the form ósekju in this prepositional phrase as the dative singular of the noun ósekja f. ‘innocence’. Following a discussion of the evidence for the nouns ósekja and sekja and phrases with the preposition að, it is argued that it would be more appropriate to consider ósekju an Old Icelandic dative singular neuter of the adjective ósekr ‘not convicted, not guilty’. A comparable example, the ambiguous phrase með heilbrigðu, is just as likely to contain dat.sg.n. heilbrigðu of the adjective heilbrigðr(‘with (everything) safe and sound’) as the dative of a feminine substantive.
Vélþýðingar á íslensku og Apertium-þýðingarkerfið
Authors: Björnsdóttir Ingibjörg Elsa
Published: September 2019

There has been rapid development in language technology and machine translation in recent decades. There are three main types of machine translation: statistical ma-chine translation, rule-based machine translation, and example-based machine translation. In this article the Apertium machine translation system is discussed in particular. While Apertium was originally designed to translate between closely related languages, it can now handle languages that are much more different and variable in structure. Anyone can participate in the development of the Apertium system since it is an open source soft ware. Thus Apertium is one of the best options available in order to research and develop a machine translation system for Icelandic. The Apertium system has an easy-to-use interface, and it translates almost instantly from Icelandic into English or Swedish. However, the system still has certain limitations as regards vocabulary and ambiguity.

Question of use of local resources for ensuring energy needs and in particular production of biogas remains relevant. Grain crops which condition at initial stages of vegetation is inadmissible for receiving a qualitative harvest can become a prospect of raw materials for creation of biogas. The optimum tool for monitoring of a condition of vegetable cultures is considered UAV which use does not depend on the existence of clouds. The purpose of this research is an assessment by results of the use of the UAV of potential quality of winter wheat in the phrase "exit in a tube" about the expediency of its use for the production of biogas. Measurements of intensity of components of the color of wheat were taken in the conditions of a research hospital, the condition of a flag leaf was estimated visually at land researches. By results of work it was offered the indicator stressful index, it is constructed on the definition of a condition of a flag leaf which is the indicator of the formation of grain yield in wheat. It was shown expediency of account on monitoring of wheat, except the average value of intensity, the brightness of the channel of color and size of semi-distribution. This size can be considered as an additional parameter during the creation of stressful indexes, and also to testify about a condition of transition between stages of growth and development of plants. It is experimentally proved that color portraits of wheat have to be created under concrete stages of organogenesis. Taking into account that the duration of stages is several days, namely the UAV that can directly be used by agricultural producers, is the optimum tool for requirements of exact agriculture.

An outbreak of Bacillus cereus toxin-mediated emetic and diarrhoeal syndromes at a restaurant in Canberra, Australia 2018
Authors: Thirkell Callum E , Sloan-Gardner Timothy S , Kaczmarek Marlena C , Polkinghorne Ben
Published: September 2019

A cluster of gastrointestinal illness was detected following receipt of a complaint of becoming ill after a multi-course dinner at a restaurant in Canberra, Australian Capital Territory (ACT), Australia. The complaint led to an investigation by ACT Health.
Food samples retained by the restaurant for microbiological analysis returned an unsatisfactory level of Bacillus cereus in beef (19,000 colony forming units/gram [cfu/g]) and a satisfactory level in arancini (50 cfu/g). These positive samples underwent whole genome sequencing and genes encoding diarrhoeal toxins were detected with no laboratory evidence of the emetic toxin. No stool specimens were collected.
A cohort study was undertaken and 80% (33/41) of patrons took part in a structured interview. There was no significant difference in age or sex between those ill and not ill. Due to universal exposure most foods were unable to be statistically analysed and no significant results were found from the food history. The ill cohort diverged into two distinct groups based on incubation period and symptoms suggesting this outbreak involved B. cereus intoxication with both diarrhoeal and potentially emetic toxins. Some hygiene practices during food preparation were noted to be inadequate and heating and cooling procedures were unverified when questioned.
A combination of the incubation periods and symptom profile, food laboratory evidence, and genomic sequencing of the B. cereus diarrhoeal gene suggest a probable aetiology of B. cereus intoxication. Public health action included the restaurant rectifying hygiene practices and documenting heating/cooling procedures.

Published: September 2019

From 1 January to 31 December 2017, 36 institutions around Australia participated in the Australian Enterococcal Sepsis Outcome Programme (AESOP). The aim of AESOP 2017 was to determine the proportion of enterococcal bacteraemia isolates in Australia that were antimicrobial resistant, and to characterise the molecular epidemiology of the E. faecium isolates. Of the 1,137 unique episodes of bacteraemia investigated, 95.2% were caused by either E. faecalis (52.9%) or E. faecium (42.3%). Ampicillin resistance was not detected in E. faecalis but in 89.6% of E. faecium. Vancomycin non-susceptibility was reported in 0.3% and 47.0% of E. faecalis and E. faecium respectively. Overall 50.9% of E. faecium harboured vanA or vanB genes. For the vanA/B positive E. faecium isolates, 49.6% harboured vanB genes and 49.2% vanA genes; 1.2% harboured vanA and vanB genes. The percentage of E. faecium bacteraemia isolates resistant to vancomycin in Australia is significantly higher than that seen in most European countries. E. faecium consisted of 76 multilocus sequence types (STs) of which 77% of isolates were classified into nine major STs containing ten or more isolates. All major STs belong to clonal cluster (CC) 17, a major hospital-adapted polyclonal E. faecium cluster. Seven of the nine predominant STs (ST80, ST1421, ST17, ST296, ST555, ST203 and ST18) were found across most regions of Australia. The most predominant clone was ST17 which was identified in all regions except the Australian Capital Territory, the Northern Territory and Tasmania. Overall 60.7% of isolates belonging to the nine predominant STs harboured vanA or vanB genes. The AESOP 2017 has shown enterococcal bacteraemias in Australia are frequently caused by polyclonal ampicillin-resistant high-level gentamicin resistant vanA or vanB E. faecium which have limited treatment options.

Published: September 2019

The teaching of English in Indonesia has been started from elementary school until university level because students are expected to have good knowledge of English as the international language. In order to compete with people all over the world, English learners should be able to use English both in written and spoken form. The teaching of English in SMAINUS has been conducted in a fun way supported by the innovative teacher and interactive technique. Consequently, students have positive perceptions toward English and are more motivated to improve their English. However, there is no any English club, especially on English Conversation Club (ECC) that can facilitate students to do speaking practice outside the class to improve their productive skill rapidly. Therefore, this program is the starting point of ECC in SMAINUS. This paper aims at exploiting students’ perceptions of ECC program to create English environment.

Since 2007 Government of Indonesia implementing mass National Community Empowerment Program, well-known as PNPM which is reaches thirty three provinces. This program has become an important development program for national as well as local and regional level across Indonesia. The program using bottom up approaches since it implemented based on fostering local community participation; strengthening local community organization with the ultimate goals is to reduce poverty at local level. The regulation and technical guidance affirmed by ministry and it is running by local community organization. The study goes to examine the research findings that the Indonesia CDD’s program is effective to enhance local participation.  It also examines the extent to which research findings used to increase higher public participation on this project  since the program focus on small scale infrastructure and mostly it has taken up uniform activity of the program agenda all over the countries. The program basically focus on building basic need infrastructure projects, such as, piping drinking water project, paving small roads at rural or paving narrow ‘labyrinth’ at dense urban area. However, hardly to find innovation program from the local governments since they have no adopted anything remotely near the ‘National Package’. Moreover, the quality of participation is still questionable.  This study concludes with a discussion of the limits to evaluation and recommend stragies for promoting forther practice and methods of The Urban-Poverty Project public participation evaluation. Based on the literature study, this paper try to give contribution on an understanding of the successful of project implementation, in turn could be used to formulate future public partcipation project.

An Intelligent Artificial Neural Network Modeling of a Magnetorheological Elastomer Isolator
Authors: Zhao Shiping , Ma Yong , Leng Dingxin
Published: September 2019

Recently, magnetorheological elastomer (MRE) has been paid increasingly attention for vibration mitigation devices with the benefits of low power cost, fail safe performances, and fast responses. To make full use of the striking advantages of MRE device, a highly precise model should be developed to predict its dynamic performances. In the work, an MRE isolator in shear–squeeze mixed mode is developed and tested under dynamic loadings. The nonlinear performances in various displacement amplitude and currents are shown. An artificial neural network model with a back-propagation algorithm is proposed to characterize the nonlinear hysteresis of MRE isolator for its implementation in vibration control applications. This model utilized the displacement, velocity, and applied current as inputs and output force as output. The results show that the proposed model has high modeling accuracy and can well portray the complicated behaviors of MRE isolator with different excitations, which shows a fundamental basis for structural vibration control.
Circling Round Vitruvius, Linear Perspective, and the Design of Roman Wall Painting
Authors: Small Jocelyn Penny
Published: September 2019

Many scholars believe that linear perspective existed in classical antiquity, but a fresh examination of two key texts in Vitruvius shows that 1.2.2 is about modularity and symmetria, while 7.Pr.11 describes shading (skiagraphia). Moreover, these new interpretations are firmly based on the classical understanding of optics and the history of painting (e.g., Pliny the Elder). A third text (Philostratus, Imagines 1.4.2) suggests that the design of Roman wall painting depends on concentric circles. Philostratus’ system is then used to successfully make facsimiles of five walls, representing Styles II, III, and IV of Roman wall painting. Hence, linear perspective and its relatives, such as Panofsky’s vanishing vertical axis, should not be imposed retrospectively where they never existed.
Service-Oriented Model Encapsulation and Selection Method for Complex System Simulation Based on Cloud Architecture

With the rise in cloud computing architecture, the development of service-oriented simulation models has gradually become a prominent topic in the field of complex system simulation. In order to support the distributed sharing of the simulation models with large computational requirements and to select the optimal service model to construct complex system simulation applications, this paper proposes a service-oriented model encapsulation and selection method. This method encapsulates models into shared simulation services, supports the distributed scheduling of model services in the network, and designs a semantic search framework which can support users in searching models according to model correlation. An optimization selection algorithm based on quality of service (QoS) is proposed to support users in customizing the weights of QoS indices and obtaining the ordered candidate model set by weighted comparison. The experimental results showed that the parallel operation of service models can effectively improve the execution efficiency of complex system simulation applications, and the performance was increased by 19.76% compared with that of scatter distribution strategy. The QoS weighted model selection method based on semantic search can support the effective search and selection of simulation models in the cloud environment according to the user’s preferences.

Published: September 2019

The aim of this study was to monitor acute response patterns of autonomic and central nervous system activity during an encounter with Antarctica by synchronously recording heart rate variability (HRV) and electroencephalography (EEG). On three different time-points during the two-week sea journey, the EEG and HRV were recorded from nine male scientists who participated in “The First Turkish Antarctic Research Expedition”. The recordings were performed in a relaxed state with the eyes open, eyes closed, and during a space quantity perception test. For the EEG recordings, the wireless 14 channel EPOC-Emotiv device was used, and for the HRV recordings, a Polar heart rate monitor S810i was used. The HRV data were analyzed by time/frequency domain parameters and ordinal pattern statistics. For the EEG data, spectral band power in the conventional frequency bands, as well as permutation entropy values were calculated. Regarding HRV, neither conventional nor permutation entropy calculations produced significant differences for the different journey time-points, but only permutation entropy was able to differentiate between the testing conditions. During the cognitive test, permutation entropy values increased significantly, whereas the conventional HRV parameters did not show any significant differences. In the EEG analysis, the ordinal pattern statistics revealed significant transitions in the course of the sea voyage as permutation entropy values decreased, whereas spectral band power analysis could not detect any significant difference. Permutation entropy analysis was further able to differentiate between the three testing conditions as well between the brain regions. In the conventional spectral band power analysis, alpha band power could separate the three testing conditions and brain regions, and beta band power could only do so for the brain regions. This superiority of permutation entropy in discerning subtle differences in the autonomic and central nervous system’s responses to an overwhelming subjective experience renders it suitable as an analysis tool for biomonitoring in extreme environments.
Application of a Speedy Modified Entropy Method in Assessing the Complexity of Baroreflex Sensitivity for Age-Controlled Healthy and Diabetic Subjects

The percussion entropy index (PEIorginal) was recently introduced to assess the complexity of baroreflex sensitivity. This study aimed to investigate the ability of a speedy modified PEI (i.e., PEINEW) application to distinguish among age-controlled subjects with or without diabetes. This was carried out using simultaneous photo-plethysmo-graphy (PPG) pulse amplitude series and the R wave-to-R wave interval (RRI) series acquired from healthy subjects (Group 1, number = 42), subjects diagnosed as having diabetes mellitus type 2 with satisfactory blood sugar control (Group 2, number = 38), and type 2 diabetic patients with poor blood sugar control (Group 3, number = 35). Results from PEIorginal and multiscale cross-approximate entropy (MCAE) were also addressed with the same datasets for comparison. The results show that optimal prolongation between the amplitude series and RRI series could be delayed by one to three heartbeat cycles for Group 2, and one to four heartbeat cycles for Group 3 patients. Group 1 subjects only had prolongation for one heartbeat cycle. This study not only demonstrates the sensitivity of PEINEW and PEIorginal in differentiating between Groups 2 and 3 compared with MCAE, highlighting the feasibility of using percussion entropy applications in autonomic nervous function assessments, it also shows that PEINEW can considerably reduce the computational time required for such processes.
Universality and Exact Finite-Size Corrections for Spanning Trees on Cobweb and Fan Networks
Authors: Izmailian Nickolay , Kenna Ralph
Published: September 2019

The concept of universality is a cornerstone of theories of critical phenomena. It is very well understood in most systems, especially in the thermodynamic limit. Finite-size systems present additional challenges. Even in low dimensions, universality of the edge and corner contributions to free energies and response functions is less investigated and less well understood. In particular, the question arises of how universality is maintained in correction-to-scaling in systems of the same universality class but with very different corner geometries. Two-dimensional geometries deliver the simplest such examples that can be constructed with and without corners. To investigate how the presence and absence of corners manifest universality, we analyze the spanning tree generating function on two different finite systems, namely the cobweb and fan networks. The corner free energies of these configurations have stimulated significant interest precisely because of expectations regarding their universal properties and we address how this can be delivered given that the finite-size cobweb has no corners while the fan has four. To answer, we appeal to the Ivashkevich–Izmailian–Hu approach which unifies the generating functions of distinct networks in terms of a single partition function with twisted boundary conditions. This unified approach shows that the contributions to the individual corner free energies of the fan network sum to zero so that it precisely matches that of the web. It therefore also matches conformal theory (in which the central charge is found to be c = − 2 ) and finite-size scaling predictions. Correspondence in each case with results established by alternative means for both networks verifies the soundness of the Ivashkevich–Izmailian–Hu algorithm. Its broad range of usefulness is demonstrated by its application to hitherto unsolved problems—namely the exact asymptotic expansions of the logarithms of the generating functions and the conformal partition functions for fan and cobweb geometries. We also investigate strip geometries, again confirming the predictions of conformal field theory. Thus, the resolution of a universality puzzle demonstrates the power of the algorithm and opens up new applications in the future.
