Ein Ansatz zur vernetzten Steuerung ereignisdiskreter Systeme
Authors: Zgorzelski Markus , Lunze Jan 
Published: August 2018

Zusammenfassung
Unter vernetzten ereignisdiskreten Systemen werden in diesem Beitrag geregelte Teilsysteme verstanden, die über ein Kommunikationsnetz situationsabhängig miteinander in Verbindung treten. Die Teilsysteme arbeiten weitgehend autonom und können bei Bedarf ihre Aktivitäten koordinieren, so dass sie flexibel auf äußere Anforderungen reagieren. Dieses Verhalten wird an einem Roboterbeispiel illustriert. Für die Formalisierung der autonomen und der kooperativen Arbeitsweise werden die geregelten Teilsysteme durch Eingang/Ausgangs-Automaten beschrieben. Um den kooperativen Modus ohne einen Koordinator zu realisieren, werden die Teilsysteme um Netzwerkeinheiten erweitert, die situationsabhängig eine Kooperation erkennen und diese herbeiführen. Ein Beispiel zeigt, wie auf diese Weise aus zwei autonomen Teilsystemen ein flexibles Fertigungssystem entstehen kann.
Intervallmethoden für Identifikation, Beobachter- und Reglersynthese von Finite-Volumen-Modellen thermischer Prozesse

Published: August 2018

Zusammenfassung
Sowohl die Offline-Parameteridentifikation als auch die echtzeitfähige Online-Zustandsschätzung sind im Rahmen regelungstechnischer Anwendungen weit verbreitete Fragestellungen. Die Lösung dieser Fragestellungen ist insbesondere dann anspruchsvoll, wenn gemessene Größen und Parameter nicht mit absoluter Genauigkeit bekannt sind. In solchen Fällen lassen sich intervallbasierte Repräsentationen nutzen, um einerseits gesicherte Wertebereichsschranken unsicherer Parameter zu beschreiben und andererseits garantierte Einschlüsse aller möglichen Zustandstrajektorien zu berechnen. In diesem Artikel wird hierauf aufbauend ein intervallbasierter Ansatz zur verifizierten Parameteridentifikation und Beobachtersynthese vorgestellt. Dieser Ansatz wird darüber hinaus anhand eines Finite-Volumen-Modells eines örtlich verteilten Wärmeleitungsprozesses validiert. Für die effiziente Implementierung des Schätzverfahrens wird dabei die strukturelle Systemeigenschaft der Kooperativität ausgenutzt. Diese erlaubt es, zwei voneinander unabhängige Schrankensysteme zu definieren, aus welchen sich garantierte Unter- und Obergrenzen aller Zustände des unsicherheitsbehafteten Systemmodells berechnen lassen.
Who Cares What We Speak: A Case Study at Kgoši Mampuru Correctional Facility
Authors: Mabule Dorah Riah 
Published: August 2018

Abstract
The aim of this article is to explore the dynamic of language choice and language use as well as to examine the effect of language policy on language attitudes in the Department of Correctional Services (DCS) with special reference to Pretoria Central Prison, now called Kgoši Mampuru Correctional facility where there is some resistance to the use of English as the only official language of business.
A case study was conducted at this facility to find out the language attitudes of the participants towards English as the only official language of business. A questionnaire was used to evoke the participants’ attitudes and beliefs regarding the importance of the use of other official languages (indigenous languages which, like English, also have official status) in their daily lives. A total of 60 correctional services staff and 280 offenders took part in this research study. Interviews and observations were mainly carried out at the research site to triangulate the data. Only the findings from the 280 offenders will be reported in this article.
The findings of this research study show that the participants were keen to use their languages of choice and favoured the language functions of their indigenous languages. The findings suggest that the prevailing language attitudes were in contrast with the aims of language policy at DCS thus making the effect of language planning not to be realized.
Devolved Ethnicity in the Kenya: Social, Economic and Political Perspective
Authors: Nyaura Jasper Edward 
Published: August 2018

Abstract
This paper examines the ethnicity as an issue prevailing upon the Kenyan society and its implication on the social, economic and political dimensions in Kenya. Devolved ethnicity has been seen to be on the arise since the county’s independence (1963) to date and therefore the distrust among communities is seen as an impediment to the socio-economic and political developments in Kenya. Moreover, the issues that arise include marginalization of minority ethnic communities towards accessing resources. Uneven distribution of national resources has led to underdevelopment of regions in Kenya thereby bring about regional imbalance in terms of distribution of national resources, which has negatively affected socio-economic development of the country. Negative ethnicity brings about marginalization, distrust and heightens ethnic tensions and this eventually leads to conflict, for example, the 1992, 1997 and the 2007/2008 post-election violence over the sharing and allocation of power and national resources. This paper examines ways in which ethnic problems in Kenya have been attributed to the social, economic and political perspectives and therefore provides the solution/medicine towards negative ethnicity.
Calibration of the Ductile Failure Criterion for Nickel-Based Superalloys taking into Account the Localization of the Strain
Authors: Madejski Bartosz , Socha Grzegorz 
Published: August 2018

Abstract
Static tension test allows characterization of material strength properties. This simple test provides input data for numerical calculation of structural components made of the tested alloy. Elastic, plastic and failure behavior of the structural component in question is simulated, using, for example, the FEM package, based on parameters obtained as the result of tensile testing. When using the results of the tensile test for modeling the material failure it is important to estimate correctly plastic strain corresponding to failure. It is common practice to use elongation of the specimen gage part for the calculation of failure strain. On the other side, the most popular ductile failure criterion used by engineers performing numerical simulation of the material’s behavior relies on the equivalent plastic strain as the criterial quantity. Those two parameters can differ significantly. In order to calculate the equivalent plastic strain correctly, we have to remember about strain localization (necking) appearing during tensile tests and take into account the fact that during tensile testing we have three non-zero strain tensor components. Ignoring this fact, and using only elongation as the criterial quantity can lead to enormous simulation error. This error is analyzed in this paper for nickel based superalloy tested at elevated temperatures.

Published: August 2018

AbstractThe Su-22 fighter-bomber is a military aircraft used in the Polish Air Force (PLAF) since the mid 1980’s. By decision of the Ministry of National Defence Republic of Poland, the assumed service life for this type of aircraft was prolonged up to 3200 flight hours based on the Full Scale Fatigue Test (FSFT) results. The FSFT was conducted using the real load profile defined during the Operational Load Monitoring Program (OLM) and the 3200 hour service life was also based on this load profile.In order to assure safe operation of all the 18 Su-22 aircraft, the Individual Aircraft Tracking program was introduced. The program was based on the results of the FSFT as well as the analysis of the flight parameters recorded by the THETYS onboard flight recorder.In this paper, the authors present the methodology, assumed fatigue hypothesis and preliminary results of the IAT program for the Polish Su-22.
The Effect of Anodizing Process Parameters on the Fatigue Life of 2024-T-351-Aluminium Alloy
Authors: Kudari Shashidhar K , Sharanaprabhu C. M. 
Published: August 2018

Abstract
The effect of an anticorrosive layer on the fatigue life of 2024-T-351-aluminium alloy has been studied in the present investigation. The fatigue tests were conducted on the aluminium alloy with and without anodizing to evaluate the fatigue life. The results indicate that the fatigue life of the anodized specimens is significantly shorter than that of untreated specimens. Further, experiments were conducted to evaluate the effect of the anodizing process parameters on the fatigue life of anodized specimens. These results show that the fatigue life of anodized aluminium alloy can be improved by controlling the anodizing process parameters such as process temperature, voltage, and time of immersion.
Experimental and Numerical Study of NACA and Conventional Riveting Procedure

Published: August 2018

AbstractFatigue behaviour is one of the most important properties of modern airplanes and rivets influence it strongly. According to the literature, the NACA riveting offers a multiple increase in the fatigue life of joints.The aim of this paper is to investigate the benefits offered by the NACA riveting procedure with respect to the residual stress and strain distribution after riveting as well as rivet hole expansion. Experimental and numerical approaches were adopted. The conventional riveting with both the universal and countersunk rivets was compared with the NACA riveting. The countersunk angle and depth in the case of the NACA riveting was modified somewhat relative to the values met in the literature. For these three cases, strain gauge measurements during riveting, hole expansion measurements and FE calculations were performed. The hole expansion measurement with the use of Computer Tomography(CT) was proposed.Only the FE calculations unambiguously indicate better fatigue properties of the NACA riveting. The proposed method of hole expansion measurement requires further research to increase its accuracy.
Durational contrast in gemination and informativity
Authors: Sano Shin-Ichiro 
Published: August 2018

Abstract
Recent studies in Message Oriented Phonology (MOP) have provided increasing evidence that informativity plays a non-trivial role in linguistic behavior. This paper provides a case study of MOP focusing on the durational contrast of singleton and geminate consonants in spoken Japanese. In modern Japanese, short consonants (singletons) and long consonants (geminates) are lexically contrastive, and the durational properties of these consonants are affected by a variety of factors. This provides a useful test of the assumptions of MOP. Based on the assumption that the higher the informativity, the more robustly the contrast is phonetically implemented, this study examines the hypothesis that the durations of singletons and geminates increase or decrease according to the informativity of their durational contrast. The study confirms that (i) the distribution of singletons and geminates is affected by the manner of articulation and positional differences (morpheme-initial, medial, and final); (ii) the distributional differences follow from the informativity of contrasts as represented by Shannon’s entropy; and (iii) the durational contrast is enhanced by the presence or absence of a minimal pair.

Magnetohydrodynamic(MHD) Boundary Layer Flow of Eyring-Powell Nanofluid Past Stretching Cylinder With Cattaneo-Christov Heat Flux Model
Authors: Ibrahim Wubshet , Hindebu Bullo 
Published: August 2018

AbstractThis study analyzed the MHD boundary layer flow of Eyring-Powell nanofluid past stretching cylinder with Cattaneo-Christov heat flux model. The governing non-linear partial differential equations corresponding to the momentum, energy and concentration have been formulated and transformed into a set of non-linear ordinary differential equations by using similarity transformations. Then the resulting non-linear high order ordinary differential equations of momentum, energy and concentration, subjected to boundary conditions were solved numerically by utilizing the second-order accurate implicit finite difference method known as Keller-Box which is programmed in the MATLABR2017b software. The results indicated that the velocity profile increases as the Eyring-Powell fluid parameterMand the curvature parameterγincrease but it decreases as the magnetic parameterHaincreases. Both the temperature and the concentration profiles have revealed an increment pattern for large values of the magnetic parameterHaand the thermophoresis parameterNtbut a decrement manner with increasing values of the Eyring-Powell fluid parameterM. The Brownian motion parameterNbhas shown an opposite influence on the temperature and the concentration profiles. The results also depicted that the local skin friction coefficient increases with increasing in Eyring-Powell fluid parameterM, magnetic parameterHa. Besides, it is found that both the local Nusselt numberNuxand the local Sherwood numberShxare higher for large vales of Eyring-Powell fluid parameterMand curvature parameterγ. Furthermore, the present results for the local skin friction coefficient, the local Nusselt number and the local Sherwood number are validated with the data of previously published literature for various limiting conditions where a very sound agreement has been attained.
On the connection coefficients and recurrence relations arising from expansions in series of modified generalized Laguerre polynomials: Applications on a semi-infinite domain
Authors: Doha E.H. , Youssri Y.H. 
Published: August 2018

Abstract
Herein, three important theorems were stated and proved. The first relates the modified generalized Laguerre expansion coefficients of the derivatives of a function in terms of its original expansion coefficients; and an explicit expression for the derivatives of modified generalized Laguerre polynomials of any degree and for any order as a linear combination of modified generalized Laguerre polynomials themselves is also deduced. The second theorem gives new modified generalized Laguerre coefficients of the moments of one single modified generalized Laguerre polynomials of any degree. Finally, the third theorem expresses explicitly the modified generalized Laguerre coefficients of the moments of a general-order derivative of an infinitely differentiable function in terms of its modified generalized Laguerre coefficients. Some spectral applications of these theorems for solving ordinary differential equations with varying coefficients and some specific applied differential problems, by reducing them to recurrence relations in their expansion coefficients of the solution are considered.
Records of the Ornate Hawk-eagle, Spizaetus ornatus (Daudin, 1800) (Accipitridae), from the state of S&atilde;o Paulo, southeastern Brazil

Published: August 2018

We review the distribution of the Ornate Hawk-eagle, Spizaetus ornatus (Daudin, 1800), in the state of São Paulo, reporting localities with records of the species. Most locations where the species has been historically documented have no recent records, especially to the west of the large remnants of forest in the coastal mountain ranges. Most current records come from Serra de Paranapiacaba, southwestern São Paulo, whereas no records exist within the Cerrado domain. Unlike the neighboring state of Minas Gerais, where it is found in fragmented landscapes, in São Paulo, the species occurs exclusively within protected areas in large blocks of Atlantic Forest.

Published: August 2018

Abstract

Background
Scant real-world data exist on the clinical outcomes associated with the use of bevacizumab-containing chemotherapy (B+CT) in patients with metastatic colorectal cancer (mCRC). The primary objective of the GRETA cohort study was to compare the overall survival (OS) of patients with mCRC treated with first-line B+CT versus chemotherapy (CT) alone, in an Italian clinical practice setting.

Materials and Methods
Incident patients with mCRC were identified during the period 2010–2012 from five population-based cancer registries in Italy. Cases were linked to regional health care utilization databases to obtain the entire spectrum of health services provided to each patient. Patients starting a first-line treatment with B+CT or CT alone within 90 days from the diagnosis were included in the study cohort. A propensity score (PS) method was applied to account for residual confounding.

Results
Of 480 patients with mCRC included in the study cohort, 21.0 received first-line B+CT, and 79.0% received CT. Patients receiving B+CT were younger (p &lt; .001) and underwent surgery more frequently (p = .001). The median OS was 22.5 and 14.6 months for B+CT and CT, respectively (p = .011). The corresponding hazard ratios adjusted by multivariate modeling and PS matched analysis were 0.82 (95% confidence interval [CI], 0.62–1.08) and 0.86 (95% CI, 0.56–1.33), respectively. Similar results were observed after subgrouping by age and surgery.

Conclusion
In this Italian real-world setting of unselected mCRC, the OS of patients treated with B+CT was consistent with previous observational and patient-registry studies. However, definitive evidence of an improvement in OS cannot be drawn.

Abstract

Background
The 2016 World Health Organization Classification of Central Nervous System Tumors categorizes gliomatosis cerebri growth pattern (GC) as a subgroup of diffuse infiltrating gliomas, defined by extent of brain involvement on magnetic resonance imaging (MRI). Clinical and radiographic features in GC patients are highly heterogeneous; however, prognosis has historically been considered poor.

Subjects, Materials, and Methods
We performed a retrospective search for patients at our institution meeting radiographic criteria of primary, type I GC (defined as diffuse tumor infiltration without associated tumor mass and contrast enhancement on MRI) and analyzed their clinical, imaging, and histopathologic features.

Results
A total of 34 patients met radiographic criteria of primary, type I GC, and 33 had a confirmed histologic diagnosis of an infiltrating glial neoplasm. Age &gt;47 years at diagnosis was associated with worse overall survival (OS) compared with age ≤47 years (hazard ratio [HR] 1.04, 95% confidence interval [CI] 1.01–1.07, p = .003). Patients with grade 2 tumors demonstrated a trend for improved OS compared with those with grade 3 tumors (HR 2.65, 95% CI 0.99–7.08, p = .051). Except for brainstem involvement, extent or location of radiographic involvement did not detectably affect clinical outcome. IDH mutation status identified a subgroup of GC patients with particularly long survival up to 25 years and was associated with longer time to progression (HR 4.81, 95% CI 0.99–23.47, p = .052).

Conclusion
Patients with primary, type I GC do not uniformly carry a poor prognosis, even in the presence of widespread radiographic involvement. Consistent with other reports, IDH mutation status may identify patients with improved clinical outcome. Molecular characterization, rather than MRI features, may be most valuable for prognostication and management of GC patients.

Published: August 2018

Balkanlar beş asırdan
fazla bir süre Osmanlı hâkimiyetinde kalmıştır. Balkanların fethinin ilk
yıllarından itibaren Osmanlı burada sistemli bir iskân politikası yürütmüştür.
Fethettiği yerlere Anadolu’nun değişik bölgelerinden getirdiği Türk-Müslüman
halkı yerleştirmiştir. İlk fetihler sonucu gerçekleştirilen iskân politikasıyla
bölge, kısa sürede Türkleşmiş ve İslamlaşmıştır. Bölgede yaşanan demografik
değişiklikle beraber yoğun bir imar faaliyeti yürütülmüştür. Mevcut şehirler
yeni bir anlayışla imar ve ihya edilirken, yeni şehir ve yerleşim yerleri de
kurulmuştur. Türklerin bölgeye iskânı ile birlikte imar faaliyetleri başlamış
ve çok sayıda han, hamam, medrese, cami ve mescidin inşası
gerçekleştirilmiş, böylelikle Türk-İslam kültür ve medeniyeti bu topraklara
yerleşmeye başlamıştır. Osmanlı Devletinin Balkanlardaki fetih, iskân ve imarı
belirli plan çerçevesinde yürütülmüştür. 1361 yılında Dimetoka’nın alınmasıyla
Osmanlı egemenliği Yunanistan’da kurulmaya başlanmıştır. XIV. yüzyılın
sonlarına doğru Dimetoka’nın fethine müteakip, Yunanistan’ın orta kısmı olan
Tesalya Bölgesi Osmanlı hâkimiyetine girmiştir. Burada idari birim olarak
Tırhala Sancağı kurulmuş ve sancak yaklaşık beş asır Osmanlı idari
taksimatındaki yerini korumuştur. 1881 yılında imzalanan İstanbul
Antlaşması’yla Yunanistan’a devredilen sancak, bünyesindeki birçok Osmanlı
mimari eser ve emlakını da Yunanistan’a terk etmiştir. Bu çalışma, vakıf
kayıtlarını esas alarak, sancaktan Yunanistan’a terk edilen Osmanlı mirasını
ortaya koymayı amaçlamaktadır. Bu bağlamda Tırhala Sancağı kazalarından
Yunanistan’a terk edilen vakıf ve onlara bağlı emlakın çeşidi ve sayısı
verilmiştir.
