Coordinated closed-loop voltage control by using a real-time Volt/VAR Optimization function for MV distribution Networks
No full textAdvanced Distribution Management Systems (DMS) functions in general and Volt/Var Optimization (VVO) function in particular are forefront tools for reliable and economic operation of distribution Networks. By using real time calculation results from VVO, there is a potential for closed-loop voltage control and sending set-points to tap changers and capacitor banks. The major challenge for such closed-loop voltage control is the possibility of larger computation time for optimization problem and also delays associated to the two-way communication platform between the VVO engine and field
through the SCADA system. The objective of this paper is to develop the idea of closed-loop voltage control by utilizing a VVO engine with a full mixed integer linear programming (MILP) model for solving optimization problem for real-time and planning applications. Optimization problems are implemented
in GAMS and have been tested on a real small MV distribution network

THE LURE OF THE IMAGE KEBOHONGAN PADA NARASI PEREMPUAN DALAM SYNGUE SABOUR PIERRE DE PATIENCE KARYA ATIQ RAHIMI
No full textThis study aims to determine the position of the author in women narration. With Rahimi’s background as a feminist, he said that with his novel he voiced the voices of Afghan women. Rahimi offered a strong female figure in the middle of the patriarchal shackles who is able to fight the system. The problem of this study is Rahimi’s ambiguity in narrating women. To determine the position of the author, the research uses the concept of the lure of the image belongs to Lidia Curti. The lure of the image is an offer provided by the author to give positions to women that are in fact not provided by them. Based on the research conducted, the results show that Rahimi keeps women as objects in a patriarchal world. In this case he is not able to pull the women out of the patriarchal zone. The space given to women by Rahimi reinforces male power. What Rahimi written in this novel is the lure of the image according to Curti’s concept which explains it as an image of women given by author or known as female gaze
Smith Professor Hillel Y. Levin offers his thoughts on the U.S. Supreme Court’s decision on U.S. v. Rahimi
No full textSmith Professor Hillel Y. Levin offers his thoughts on the U.S. Supreme Court’s decision on U.S. v. Rahimi:
What did the Supreme Court do in Rahimi?
As expected, the Court reversed the Fifth Circuit and held that when an individual has been found by a court to pose a credible threat to the physical safety of another, that individual may be temporarily disarmed consistent with the Second Amendment. The decision was 8-1, with only Justice Thomas dissenting.
On what basis did the Supreme Court decide the case?
The Court held that when looking for historical analogues of modern-day restrictions on firearms, it is not necessary to find a perfectly equivalent regulation from the Founding or post-Civil War eras. In the words of Chief Justice Roberts, the author of the majority opinion, the Second Amendment permits more than just those regulations identical to ones that could be found in 1791. It is sufficient that there be sufficient historical analogues that impose similar burdens or restrictions on the right to bear arms for similar reasons. Here, the Court concluded that the country has a tradition of disarming individuals who pose a clear threat of physical violence to another, even if not quite in the same manner as the law that was applied to Rahimi.
Does this clarify Bruen? How will it impact other cases?
This was a fairly narrow opinion. The Court kept the Bruen regime intact and gave little guidance to lower courts in applying it to other kinds of regulations. At most, the Court clarified that historical analogues need not be perfect in order to justify a modern restriction. However, lower courts will continue to struggle to determine just how similar a modern restriction must be to the historical analogue.

Domestic violence against women in Atiq Rahimi\u27s The Patience Stone
No full textDomestic violence against women is a common social ill that destroys thousands of women?s lives worldwide (Khan, 2000). However, the growth of this concern, particularly in developing countries such as Afghanistan, requires more scholarly attention not only because the lives of many Afghan women are affected by it, but also because it remains overlooked due to socio-cultural norms that consider discussions about it as taboo. Of late, however, there is a rising trend among members of the Afghan Diaspora in portraying domestic violence against their womenfolk back home through such artistic mediums as fiction (Parveen, 2015). Therefore, in this paper, we shall examine the manifestations of domestic violence against women in the Afghan context through a textual analysis of The Patience Stone by Atiq Rahimi, an author belonging to the Afghan Diaspora. Originally written in French, this breakthrough novella highlights the harsh reality of the misery suffered by many Afghan women on a regular basis, notably the various forms of domestic violence that they have to endure in the poverty-stricken, war-torn and staunchly patriarchal environment of their homeland. Through a feminist reading of The Patience Stone (2011), we shall examine Rahimi?s depictions of domestic violence against women in the novella as a highly engendered phenomenon resulting from gender inequality and a sexist hierarchy of power prevalent in Afghan society. Furthermore, this paper is outlined based on three main forms of domestic violence, namely physical, sexual and emotional abuse, which are depicted in The Patience Stone through the novella?s female characters, notably the main protagonist
Characterization of the passive layer on ferrite and austenite phases of super duplex stainless steel
No full textIn this study, we report on a combined microscopic, analytical and electrochemical characterization of the nanoscopic passive layer on a tungsten‑molybdenum-containing super duplex stainless steel. We used scanning transmission electron microscopy/energy dispersive X-ray spectroscopy, scanning Kelvin probe force microscopy, scanning tunneling spectroscopy, and Mott–Schottky electrochemical impedance spectroscopy analysis to correlate the local chemical composition and electronic properties of passive layers on austenite and ferrite phases. The passive layer on the ferrite phase contains a higher amount of Mo, W, and Cr, which accommodates a higher nobility of ferrite and a higher local energy of the band gap compared to those on the austenite. The two aforementioned phases exhibit a different composition and semi-conductive properties of their passive layers leading to dissimilar local corrosion susceptibility. These findings are of pivotal importance in further studies of austenite and ferrite phase resolved corrosion resistance of duplex stainless steel demanding a dedicated alloying strategy.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.(OLD) MSE-6QN/Zandbergen La
Atiq Rahimi’s Exophonic Entanglements: Multilingual and Multimodal Poetics
No full textIn 2008, first-generation Afghan migrant novelist-artist Atiq Rahimi published his first translingual work in French, Syngué Sabour: Pierre de patience. This article interrogates his multilingual and multimodal aesthetics across his translingual oeuvre. In his exophonic novel Les Porteurs d’eau (2019), Rahimi valorizes a polyvocal and culturally diverse Central Asian history. The Prix Goncourt–awarded author introduces Afghanistan’s past and present beyond its intracultural challenges. The epitome of the Rahimi-esque aesthetic is the author’s publication L’Invité du miroir (2020), which acts as a revolt, a transnational dialectic crossroads where multilingual fiction meets classical Persian calligraphy and nonfiction to explore the human spirit
Accuracy of Working Length Determination using NovApex and Root-ZX Apex Locators: An in vitro Study
No full textABSTRACT
Introduction
This ex vivo study evaluated the accuracy of the Root-ZX electronic apex locator (EAL) (J. Morita, Tokyo, Japan) and the NovApex (Forum Technologies, Rishon Lezion, Israel) in determining the working length (WL) during endodontic treatment.
Materials and methods
Forty extracted single-rooted human teeth were selected for this study. The actual WL was measured with visual technique by a size #15 k-file under magnification. Then, the canal lengths were measured electronically with both Root-ZX and NovApex apex locators within ±0.5 and ±1 mm. Mean percentage of data was analyzed between groups using paired t-test, with a statistically significant level of p < 0.05.
Results
The accuracy of NovApex apex locator was 85% within ±0.5 mm and 92.5% within ±1 mm. The accuracy of Root-ZX apex locator was 70% within ±0.5 mm and 97.5% within ±1 mm. There was no significant difference between the accuracy of the two EALs.
Conclusion
Both the NovApex and Root-ZX EALs are useful for measuring the WL with high accuracy.
Clinical significance
Given the importance of accurate WL determination in the success of endodontic treatments, the accuracy of different apex locators should be evaluated.

Prevalence of two root canals in human mandibular anterior teeth in an Iranian population
No full textBackground: Complete debridement and obturation of the root canal system is a key factor in successful endodontic treatment and the operator should therefore have thorough knowledge of the root canal morphology of the teeth. Numerous studies have been carried out to investigate the canal configuration of different tooth types in various populations.
Aims: The aim of the present study was to investigate the internal anatomy of mandibular incisors and canines in an Iranian population.
Materials and Methods: A total of 463 mandibular anterior teeth, including 186 centrals, 128 laterals, and 149 canines, were examined. A standard clearing technique was used to make the teeth transparent. India ink was injected into the canals of the teeth and the samples were examined with a magnifying glass. The root canal configurations were categorized according to the Vertucci classification.
Results: All the incisors in this study had one root, and 12.08% of the canines had two roots. We found a slightly higher prevalence of the second canal in incisors than in canines (36.62% vs. 20.48%). However, the probability of canines having two separate apical foramina was higher than that for incisors (12.08% vs. 0.64%).
Conclusions: In view of the high prevalence of two-canaled mandibular anterior teeth found in this study, it would be prudent to assume that any mandibular anterior tooth being treated is two-canaled until a thorough search proves otherwise
