Asset Administration Shell in Manufacturing: Applications and Relationship with Digital Twin

Within Industry 4.0 the communication between the physical and the cyber part of manufacturing system faces an ever-growing rise in complexity. The Asset Administration Shell (AAS) is an information framework, within Industry 4.0, that describes the technological features of an asset. It was created to present data and information in a structured and semantically defined format, allowing for interoperability. The work addresses the industrial implementation of AAS, where a systematic literature review has been carried out to investigate the features of the implemented AAS metamodel, and the tools used for the realization of the models. A study of the convergence present in literature between the AAS and Digital Twin (DT) has also been carried out. This paper presents a reference of AAS tools and information for industry practitioners, as well as suggestions for research gaps in the standardization of AAS information modelling.

Diasporic Women’s Mutability in South Asian Postcolonial Literature

Though Western scholarship tends to homogenize South Asian experiences, researchers and novelists shed light on different classes of South Asian postcolonial and migratory women who experience mutability, or the internal and external changes as a trauma response after British colonial rule ended and the 1947 Partition abruptly fractured national identity. Though this mutability has positive and negative transformative qualities, it also allows women characters the power to remove themselves from cycles of oppression, work towards healing, and transforming their physical bodies from sites of repressed trauma to sites of expression and agency. What binds them is not only their physical movement and migration, but the timeless and collectively shared trauma of acculturation and assimilation, in the face of determining their identities. This work investigates how mutability is represented in distinct postcolonial female characters in several of Saadat Hasan Manto’s short fiction stories on Partition, Monica Ali’s Brick Lane, Alka Joshi’s The Henna Artist, Mahasweta Devi’s “The Hunt”, and Tahmima Anam’s A Golden Age

Evaluasi Kinerja Jalan dan Penataan Arus Lalu Lintas pada Akses Dermaga Ferry Penyeberangan Sianta

Kepadatan lalu lintas sering terjadi pada jam-jam sibuk di mana sering terjadi kemacetan pada sebagian jalan raya penting di Pontianak. . Jalan Khatulistiwa yang merupakan juga akses dermaga Ferry Penyeberangan Siantan yang menghubungkan juga dengan lembaga pendidikan, perkantoran, pasar, pertokoan dan pemukiman sehingga dapat menyebabkan konflik arus lalu lintas pada persimpangan yang dapat menghambat kelancaran arus lalu lintas. Untuk merencanakan suatu persimpangan yang baik perlu adanya volume lalu lintas dari persimpangan itu sendiri. Volume lalu lintas ini didapatkan dari hasil survey lalu lintas yang dilaksanakan pada hari Jum'at, Sabtu, Minggu dan Senin. Metode pengambilan data dilakukan dengan alat bantu counter hand. Kemacetan yang terjadi pada persimpangan dikarenakan adanya konflik pada persimpangan yang dapat menghambat kelancaran arus lalu lintas. Hasil penelitian dengan Pengaturan arus lalu lintas didapat alternatif pertama yakni mengurangi hambatan samping dari tinggi menjadi rendah maka ( FRSU = 0,95) misalnya dengan pemasangan rambu lalu lintas larangan serta dilakukan penertiban pedagang kaki lima disekitar simpang sehingga diharapkan berkurangnya hambatan samping disekitar simpang didapat derajat kejenuhan simpang pertama 0,69 dan simpang kedua 0.87. Alternatif kedua mengurangi hambatan samping dari tinggi menjadi rendah maka ( FRSU = 0,95) misalnya dengan pemasangan rambu lalu lintas larangan berhenti serta dilakukan penertiban pedagang kaki lima disekitar simpang. Kemudian kendaraan yang keluar dari kapal ferry dialihkan kearah pasar puring dengan mengurangi hambatan samping yang tinggi menjadi rendah dengan cara pemasangan rambu lalu lintas dan penertiban pedagang kaki lima diruas jalan pasar puring dan disekitar simpang didapat derajat kejenuhan simpang pertama 0,63, simpang kedua 0,57 dan simpang ketiga 1,25. Alternatif ketiga Penerapan alternatif kedua dengan menggunakan simpang bersinyal serta pada simpang ke III dilakukan pelebaran dari 6 M menjadi 12 M pada jalan khatulistiwa didapat derajat kejenuhan simpang pertama 0,583, simpang kedua 0,548 dan simpang ketiga 0,536. Sehingga pengaturan arus lalu lintas dengan alternatif ketiga dianggap lebih efektif. Kata-kata kunci

X-ray constraints on the fraction of obscured AGN at high accretion luminosities

The wide-area XMM-XXL X-ray survey is used to explore the fraction of obscured AGN at high accretion luminosities, $L_X (\rm 2-10 \, keV) > 10^{44} \, erg \,s ^{-1}$, and out to redshift $z\approx1.5$. The sample covers an area of about $\rm14\,deg^2$ and provides constraints on the space density of powerful AGN over a wide range of neutral hydrogen column densities extending beyond the Compton-thick limit, $\rm N_H\approx10^{24}\,cm^{-2}$. The fraction of obscured Compton-thin ($\rm N_H=10^{22}-10^{24}\,cm^{-2}$) AGN is estimated to be $\approx0.35$ for luminosities $L_X(\rm 2-10\,keV)>10^{44}\,erg\,s^{-1}$ independent of redshift. For less luminous sources the fraction of obscured Compton-thin AGN increases from $0.45\pm0.10$ at $z=0.25$ to $0.75\pm0.05$ at $z=1.25$. Studies that select AGN in the infrared via template fits to the observed Spectral Energy Distribution of extragalactic sources estimate space densities at high accretion luminosities consistent with the XMM-XXL constraints. There is no evidence for a large population of AGN (e.g. heavily obscured) identified in the infrared and missed at X-ray wavelengths. We further explore the mid-infrared colours of XMM-XXL AGN as a function of accretion luminosity, column density and redshift. The fraction of XMM-XXL sources that lie within the mid-infrared colour wedges defined in the literature to select AGN is primarily a function of redshift. This fraction increases from about 20-30% at z=0.25 to about 50-70% at $z=1.5$.Comment: MNRAS accepte

Energy-Momentum Distribution: A Crucial Problem in General Relativity

This paper is aimed to elaborate the problem of energy-momentum in General Relativity. In this connection, we use the prescriptions of Einstein, Landau-Lifshitz, Papapetrou and M\"{o}ller to compute the energy-momentum densities for two exact solutions of Einstein field equations. The spacetimes under consideration are the non-null Einstein-Maxwell solutions and the singularity-free cosmological model. The electromagnetic generalization of the G\"{o}del solution and the G\"{o}del metric become special cases of the non-null Einstein-Maxwell solutions. It turns out that these prescriptions do not provide consistent results for any of these spacetimes. These inconsistence results verify the well-known proposal that the idea of localization does not follow the lines of pseudo-tensorial construction but instead follows from the energy-momentum tensor itself. These differences can also be understood with the help of the Hamiltonian approach.Comment: 28 pages, accepted for publication in Int. J. Mod. Phys.

Qualitative and Quantitative Characterization of Textile Material by Fourier Transform Infra-Red A Brief Review

Abstract: Difference in the chemical properties of the textile materials is mainly attributed to the presence of different functional groups in their structure. Manufacturing process subjects the material to various treatments like mechanical stretching, bending, twisting, heating etc. They are liable to cause structural changes and therefore characteristics. So, knowledge of scientifically measured characterization of textile material before and after subjecting to various mechanisms of production pattern is needed. Fourier Transform Infra Red spectroscopy (FT-IR) has found preference over other techniques in this regards. It is successfully used in qualitative as well as quantitative analysis of textile substance

Does Carbon Emission Matter for Health Care Expenditure? Evidence from SAARC region using Panel Cointegration

This study investigates the impact of increased carbon emissions on per capita health expenditure exploiting the panel data with Engle – Granger based cointegration test, Fully Modified Ordinary Least Square (FMOLS) and Dynamic Ordinary Least Square (DOLS) method. Data for the South Asian Association for Regional Cooperation (SAARC) countries from 1995 to 2014 have been collected from World Development Indicators (WDI). The confirmation of integration order of the variables has been made using two panel unit root tests suggested by Im – Pesaran – Shin, 2003 (IPS) and Levin, Lin & Chu, 2002 (LLC). Following the procedure suggested by Pedroni (1999, 2003) and Kao (1999), existence of long run relationship has been examined among the variables. Application of Fully Modified Ordinary Least Square (FMOLS) and Dynamic Ordinary Least Square (DOLS) further confirmed the presence of long run significant positive relationship between carbon emissions and per capita health expenditure. The coefficients of carbon emissions varied from 0.246 to 0.355 under the model estimated by FMOLS while the coefficients varied from 0.198 to 0.283 under the model estimated by DOLS. The findings can be generalized by saying that increased carbon emissions due to environmental degradation would increase the health expenditure as well as cost of the nations
