Consensus Control Design for 360 MN Extrusion Machine Producing Process

This paper mainly addresses the issue of 360 MN extrusion machine and focuses on the stabilization control of main table attitude. We will first introduce the problem and then model the extrusion machine. As the machine is a multi-input multioutput (MIMO) and strong coupling system, it is challenging to apply existing control theory to design a controller to stabilize the main table attitude. Motivated by recent research in the field of multiagent systems, we design a consensus control protocol for our system and derive our convergence conditions based directly on Routh stability criterion. The advantages of the design are also demonstrated by numerical simulation.
The grey textures of practice and knowledge: review and framework

Purpose – The aim of this paper was to review the knowledge and practice‐related literature, as well as to develop a theoretical framework that functions like a sorting device, in order to improve our understanding about how theories are turned into practice.Design/methodology/approach – This is a theoretical paper that discusses the relationships between practice and knowledge using practice‐based lenses.Findings – This paper discusses the relationships between diverse forms of knowledge and practice, and it elaborates the cognitive mechanisms used to know how to shift from the inside to the outside view, and vice versa.Research limitations/implications – By organising a wide range of knowledge‐ and practice‐related concepts into meaningful categories, this paper contributes to overcoming the use of the concepts of knowledge and practice as universal.Practical implications – By recognising the implicit epistemological stance associated with the diverse theories and concepts, the framework may be useful i.
The Effect of Prolonged and Graded Exercise Protocols on Maximal Fat Oxidation and Fatmax in Trained Girls

Introduction: The intensity and duration of exercises are the main factors of fat oxidation and carbohydrate during the exercise. The aim of this study was to investigate the effect of prolonged and graded exercise protocols on maximal fat oxidation (MFO) and Fatmax in trained girls. Methods: Ten trained girls (age = 22.3 ±1.8 years old; weight= 53.3±3.4 kg; BMI= 20.6 ± 1.1 kg/m 2 and VO2max= 34.2±2 ml/kg/min), attended the laboratory on seven separate occasions. In the first visit, anthropometrics and maximal oxygen uptake (VO2max) measurements were assessed. In the second session, participants completed a submaximal graded exercise protocol with seven stages, 3 min per stages at intensity of 35, 40, 45, 50, 55, 60 and 65% of VO2max. Next, each participant in five separate sessions consisting of 30 min prolonged exercises performed exercises in a counterbalanced order of intensity at 40, 45, 50, 55 and 60% VO2max. For statistical analysis of data Shapiro Wilk and paired sample t-test (p≤0.05) were used. Results: The results showed that there was a significant difference between MFO (p=0.01) and Fatmax (p=0.04) after graded and prolonged exercises. Conclusion: It appears that prolonged exercise caused a higher MFO and Fatmax rather than graded exercise in trained girls.
Picky: A New Introductory Programming Language

In the authors’ experience the languages available for teaching introductory computer programming courses are lacking. In practice, they violate some of the fundamentals taught in an introductory course. This is often the case, for example, with I/O. Picky is a new open source programming language created specifically for education that enables the students to program according to the principles laid down in class. It solves a number of issues the authors had to face while teaching introductory courses for several years in other languages. The language is small, simple and very strict regarding what is a legal program. It has a terse syntax and it is strongly typed and very restrictive. Both the compiler and the runtime include extra checks to provide safety features. The compiler generates byte-code for compatibility and the programming tools are freely available for Linux, MacOSX, Plan 9 from Bell Labs and Windows. This paper describes the language and discusses the motivation to implement it and its main educational features.
Effect of nanopatterns on Kapitza resistance at a water-gold interface during boiling: A molecular dynamics study

The effect of nanopatterns on Kapitza resistance of water boiling on a gold surface is examined via molecular dynamics simulations. The TIP4P-Ew potential for water, embedded-atom model for gold, and the calibrated Lennard-Jones parameters for water-gold interactions are used to accurately predict the boiling point of water and the wetting angle of water on gold. The results show that boiling of water does not affect the Kapitza resistance of the water-gold interface. The increase of the height of nanopatterns leads to a reduction of the Kapitza resistance by increasing the interaction energy per unit area at the water-gold interface. With the increase of the width-to-spacing ratio of nanopatterns, the Kapitza resistance reduces due to the decrease of the mismatch between the vibrational density of states of water and gold.
Growth and nutrient uptake by Schoenoplectus californicus (C.A. Méyer) Sójak in a constructed wetland fed with swine slurry

Schoenoplectus californicus (C.A. Meyer), Sojak is one of the plants most used to treat wastewater in a constructed wetland. Our objective is to study the growth and nutrient uptake of Schoenoplectus californicus Cyperaceae in a constructed wetland fed with swine slurry. The methodology used to evaluate the growth of the Schoeno- plectus californicus Cyperaceae was to evaluate the allometric, relative abundance and biomass of the plants in the period 2009 - 2010. The results show that Schoenoplectus californicus had allometric growth between 31.2 to 98.4 and relative abundance between 21 to 108 individuals m -2 , during the fall and spring seasons, respectively. These results are influenced by the nitrogen content (between 0.05 to 2.0 kg N ha -1
Changes in Soil Organic Carbon, Nitrogen and Phosphorus in Modified and Native Rangeland Communities (Case study: Sisab Rangelands, Bojnord)

A bstract. Converting the native rangelands to simplified agro nomic communities causes some changes in soil carbon, nitrogen and phosphorus. Establishing of perennial plant communities on formerly cultivated rangelands is expected to stabilize soil properties and increase the amount of C, N, P stored in rangeland soils, but there is little information on what plant communities are the most effective for improvement of soil C, N, P reserves. The purpose of this study was to compare soil C, N, and P pools in ungrazed native rangelands with plant community of Festuca-Centurea with those ungrazed pastures established by sowing non-native perennial grasses ( Agropyron elongatum and Agropyron desertorum), shrubs (Kochia prostrata), and wheat cultivation in continuous dry land farming system. Study site was located in Sisab Research Station in North Khorasan Province, Iran. The results showed that the total C, N and P contents in the soils under modified plant communities were less than that for native rangeland. Soils under A. elongatum, A. desertorum and K. prostrata tended to have higher values for total C, N and P than soils cultivated annually in wheat-fallow systems. The total C and N content of soils under K. prostrata were near as native rangeland which suggests that K. prostrata can increase the soil C and N contents much more rapidly than the other perennial communities.
Evolution simulation of lightning discharge based on a magnetohydrodynamics method

In order to solve the load problem for aircraft lightning strikes, lightning channel evolution is simulated under the key physical parameters for aircraft lightning current component C. A numerical model of the discharge channel is established, based on magnetohydrodynamics (MHD) and performed by FLUENT software. With the aid of user-defined functions and a userdefined scalar, the Lorentz force, Joule heating and material parameters of an air thermal plasma are added. A three-dimensional lightning arc channel is simulated and the arc evolution in space is obtained. The results show that the temperature distribution of the lightning channel is symmetrical and that the hottest region occurs at the center of the lightning channel. The distributions of potential and current density are obtained, showing that the difference in electric potential or energy between two points tends to make the arc channel develop downwards. The arc channel comes into expansion on the anode surface due to stagnation of the thermal plasma and there exists impingement on the copper plate when the arc channel comes into contact with the anode plate.
Predicting physiological developments from human gait using smartphone sensor data

Coronary artery disease, heart failure, angina pectoris and diabetes are among the leading causes of morbidity and mortality over the globe. Susceptibility to such disorders is compounded by changing lifestyles, poor dietary routines, aging and obesity. Besides, conventional diagnostics are limited in their capability to detect such pathologies at an early stage. This generates demand for automatic recommender systems that could effectively monitor and predict pathogenic behaviors in the body. To this end, we propose human gait analysis for predicting two important physiological parameters associated with different diseases, body mass index and age. Predicting age and body mass index by actively profiling the gait samples, could be further used for providing suitable healthcare recommendations. Existing strategies for predicting age and body mass index, however, necessitate stringent experimental settings for achieving appropriate performance. For instance, precisely recorded speech signals were recently used for predicting body mass indices of different subjects. Similarly, age groups were predicted by recording gait samples from on-body and wearable sensors. Such specialized methods limit active and convenient profiling of human age and body mass indices. We address these issues, by introducing smartphone sensors as a means for recording gait signals. Using on-board accelerometer and gyroscope helps in developing easy-to-use and accessible systems for predicting body mass index and age. To empirically show the effectiveness of our proposed methodology, we collected gait samples from sixty-three different subjects that were classified in body mass index and age groups using six well-known machine learning classifiers. We evaluated our system using two different windowing operations for feature extraction, namely Gaussian and Square.
Phase field modeling of flaw-induced hydride precipitation kinetics in metals

Hydrogen embrittlement can manifest itself as hydride formation in structures when in contact with hydrogen-rich environments, e.g. in space and nuclear power applications. To supplant experimentation, modeling of such phenomena is beneficial to make life prediction reduce cost and increase the understanding. In the present work, two different approaches based on phase field theory are employed to study the precipitation kinetics of a second phase in a metal, with a special focus on the application of hydride formation in hexagonal close-packed metals. For both presented models, a single component of the non-conserved order parameter is utilized to represent the microstructural evolution. Throughout the modelling the total free energy of the system is minimized through the time-dependent Ginzburg-Landau equation, which includes a sixth order Landau potential in the first model, whereas one of fourth order is used for the second model. The first model implicitly incorporates the stress field emanating from a sharp crack through the usage of linear elastic fracture mechanics and the governing equation is solved numerically for both isotropic and anisotropic bodies by usage of the finite volume method. The second model is applied to plate and notched cantilever geometries, and it includes an anisotropic expansion of the hydrides that is caused by the hydride precipitation. For this approach, the mechanical and phase transformation aspects are coupled and solved simultaneously for an isotropic material using the finite element method. Depending on the Landau potential coefficients and the crack-induced hydrostatic stress, for the first model the second-phase is found to form in a confined region around the crack tip or in the whole material depending on the material properties. From the pilot results obtained with the second model, it is shown that the applied stress and considered anisotropic swelling induces hydride formation in preferential directions and it is localized in high stress concentration areas. The results successfully demonstrate the ability of both approaches to model second-phase formation kinetics that is triggered by flaw-induced stresses and their capability to reproduce experimentally observed hydride characteristics such as precipitation location, shape and direction.
Farm - Level Determinants of Agricultural Commercialization

The study examined the increasing commercialization of subsistence agriculture and identified the driving forces of the commercialization process. The study defined some concepts under which the process of agricultural com- mercialization was examined. The study was conducted in the three agricultural zones of Abia state, Nigeria. A total of 120 farm families spread across the state were enlisted for the study. Data were collected bimonthly for a period of six months with structured questionnaires. Data analysis involved the use of descriptive statistics and quantitative techniques. Results show that agriculture is not subsistence oriented. There is some considerable degree of market-orientation. Off- farm income was identified as important source of the commercialization of agriculture. The farm-level determinants of commercialization were labour, fertilizer and planting materials. The production elasticity of labour is high and there are diseconomies of scale. The study observes that the full potentials of agriculture have not been harnessed as agriculture is labour intensive and relies heavily on crude implements.
Interpreting MinimumWage E ff ects on Wage Distributions : A Cautionary Tale 1

It is often tempting to attempt to infer the welfare effects of minimum wage changes from empirical observations on preand post-change employment and unemployment levels and wage or earnings distributions. Using a simple model of search, matching, and bargaining, we characterize the relationship between minimum wage levels, labor market outcomes, and the welfare of labor market participants. Using observations on wage distributions before and after changes in the nominal minimum wage, we determine what can and cannot be learned about welfare impacts from changes in various features of these distributions. Our results are illustrated using simulation exercises and a small empirical example. Using U.S. data for young labor market participants in March 1997 and March 1998, we conclude that the increase in the minimum wage which occurred in September 1997 may have been welfare-enhancing, though various implications of the model are not strictly consistent with the data. Our analysis illustrates the fact that wellspecified behavioral models are required to evaluate the impact of changes in institutional constraints on the welfare of labor market participants.
Revision of the genus Frechastraea Scrutton, 1968 (Rugosa) in the Upper Frasnian of Belgium

1. IntroductionThree species of the genus Frechastraea Scrutton, 1968, namely F. phillipsastraeiformis (Moenke, 1954), F. coeni Coen-Aubert, 2012 and F. glabra Coen-Aubert, 2012, have been described by Coen-Aubert (2012) at the base of the Upper Frasnian from Belgium. In continuation of this paper, six species and one form of Frechastraea are revised herein; these are F. pentagona (Goldfuss, 1826), type species of the genus, F. minima (Rozkowska, 1953), F. micrommata (Roemer, 1852), F. kaisini (Tsien, 1978), F. cf. tungkanlingensis (Yoh, 1937), F. crassiseptata (Tsien, 1978) and F. limitata (Milne-Edwards & Haime, 1851). Most of these occurrences characterize the Upper Palmatolepis rhenana conodont Zone. As mentioned by Coen-Aubert (2012), the base of the Upper Frasnian has been fixed by the Subcommission on Devonian Stratigraphy, at the entry of the conodont Palmatolepis semichatovae. According to Sandberg et al. (1992), the entry of P. semichatovae is observed within the Lower Palmatolepis rhenana Zone, together with the first occurrence of Ancyrognathus triangularis, in bed 150 lying 2.6 m above the base of the Neuville Formation as it is exposed along the southern access road to the Lion quarry at Frasnes, on the south side of the Dinant Synclinorium. Additionally, the massive rugose coral Frechastraea coeni was noted as an excellent marker for the base of the Upper Frasnian in Belgium by Coen-Aubert (2012). During the revision of the geological map of Wallonia, several Pa
The relationship between organizational culture and the transfer of management, functions and roles in the SMES succession: A case study between Hungary and North of Portugal

This article presents the results of a study about the analysis of the relationship between organizational culture and the transfer of management, functions and roles in the succession of SME's. The study is based on a questionnaire directed to the entrepreneurs and managers of SME's. The purpose of this article is to present the results of the last edition of the questionnaire and a comparison between companies in Hungary and in the north of Portugal. The research focuses on the mapping of the state of succession (measured by the distribution of the transferred managerial functions/roles), and examine the influence of the organizational culture. What kind of culture? what kind of role will be passed? About the organizational culture: The empirical development of the Competing Values Framework was completed by Quinn & Rohrbaugh (1981) who simply wanted to find the most important criteria and factors of effective organizational operation. As a starting point, Campbell's list of 39 effectiveness indicators was used. It allowed the comprehensive description of organizational effectiveness. Some of the 39 indicators corresponded; as a result clusters could be created. In the article we conclude with the characterization of the relations between four dimensions of organizational culture: the hierarchy form, the Market type, the clan form of organization and the adhocracy, were defined along two axis (internal/external focus versus stability/flexibility). About the managerial roles, we focus on three management roles that can be find in the literature: the governor, the leader and the manager.
A record of Arcania brevifrons Chen, 1989 (Crustacea; Decapoda; Leucosiidae) from the Mediterranean coast of Israel

Two adult specimens of Arcania brevifrons, a leucosiid crab native to the Indo-West Pacific Ocean, were recently collected off the southern Israeli coast, at the southeastern Mediterranean Sea. Molecular analyses based on the mitochondrial barcoding gene cytochrome oxidase sub unit I (COI) revealed two closely related haplotypes and suggest the species has entered the Mediterranean on at least two separate occasions. This is the fourth Erythraean leucosiid species recorded in the Mediterranean Sea. The presence of an ovigerous female may indicate the existence of an established population.
ISOLATION AND CHARACTERIZATION OF INFECTIOUS BRONCHITIS VIRUS

Infectious bronchitis virus (IBV) is a Corona virus often found associated with a number of pathologic conditions in poultry. The present work is aimed at isolation and characterization of local IBV isolates including molecular characterization. Tissue samples from suspected chicken were processed and passaged in 9 day old embryonated chicken eggs through allantoic cavity route. After 3-5 passages, allantoic fluid collected and confirmation of presence of IBV was done by RT-PCR. IBV was detected in allantoic fluid harvests of four samples– IBV isolate 1, IBV isolate 2, IBV isolate 3 and IBV isolate 4. Virus inoculated embryos after 3-5 blind passages showed dwarfing and curling of the embryos which are characteristic lesions of IBV. Death was seen in some embryos 24hrs post inoculation (PI) but the rest were alive (IBV isolate 1) 96hrs PI in 9 day old embryonated eggs.

DHANALAKSHMI University : P.V. NARSIMHA RAO TELANGANA VETERINARY UNIVERSITY Year of Submission : 2017 Purification of IBV from pooled allantoic fluid was done using density gradient ultracentrifugation. SDS-PAGE profile of field isolates revealed four virus coded polypeptides: large protein spike protein (S) sub divided into S1 and S2, Nucleocapsid (N), Membrane protein (M), and Envelop protein (E). PCR products from IBV isolate 1, IBV isolate 2, IBV isolate 3 and IBV isolate 4 were sequenced and analyzed. The sequences were found to have very high identities with each other and with other IBV sequences that were available with NCBI-GenBank database. Phylogenetic tree reconstruction showed the local IBV 1, 2 isolates in one sub-group and IBV 3, 4 isolates in another subgroup clustering together with the other IBV references available in Gene bank. The results revealed that the four isolates from different places in Telangana showed identity of the local virus isolates as IBV and shared sequence similarity with reference strains, which ranged from 74.3% to 100%.

High-precision beam-based RF phase stabilization at Jefferson Lab

A non-invasive monitor has been implemented for the relative phase of the beam and the accelerating RF of each of the two CW superconducting linacs at TJNAF. Its noise level and resolution are below 0.1/spl deg/ at beam currents as low as 2 microamperes, and it been successfully tested for use in feedback correction for the overall RF accelerating phase of each linac. The 70 MHz frequency reference in each linac is phase modulated by approximately /spl plusmn/0.05/spl deg/ at different frequencies (383 and 397 Hz). A single analog beam position signal from a dispersive region is used to monitor the resulting micron-level position modulation via off-the-shelf lock-in amplifiers, which also supply the modulation signals. The off-crest phase is proportional to the first harmonic coefficient of the energy modulation. This technique can be applied as well to pulsed machines and to systems for which the beam-to-RF relative phase may be non-zero. Other applications are discussed.
Gravity/Fluid Correspondence and Its Application on Bulk Gravity with $U(1)$ Gauge Field

As the long wavelength limit of the AdS/CFT correspondence, the gravity/fluid correspondence has been shown to be a useful tool for extracting properties of the fluid on the boundary dual to the gravity in the bulk. In this paper, after briefly reviewing the algorithm of gravity/fluid correspondence, we discuss the results of its application on bulk gravity with a gauge field. In the presence of a gauge field, the dual fluid possesses more interesting properties such as its charge current. Furthermore, an external field could affect the charge current, and the Chern-Simons term also induces extra structures to the dual current giving anomalous transport coefficients.
