Smart branch and droop controller based power quality improvement in microgrids
Authors: Ray Papia , Salkuti Surender Reddy 
Published: September 2020

Abstract
This paper presents two unique smart branch controller for compensating several power quality disturbances. The first proposed intelligent branch controller comprises a series transformer with its indirectly controlled impedance by secondary voltage injection. Further, the smart controller is made adaptive and flexible. It is installed at the point of common coupling (PCC), where PCC voltage & load current can be locally acquired without the presence of a communication channel, which then tracks its references as pure sinusoidal waveforms. Therefore without any filter requirement, harmonic elimination is done by the smart branch controller. The proposed smart controller can be applied in microgrids (MGs) for multi-objective optimization of power quality (PQ). For proper elimination of harmonics and to enhance the quality of power supply, the smart branch is optimized by a droop controller, which delivers power to a constant current source and eliminates harmonics by providing an appropriate quantity of harmonic voltage to the inverter voltage. The total harmonic distortion (THD) becomes 23.06% for the voltage and 6.24% for the current with droop controller, whereas, with an only smart branch into the power network, the THD becomes 26.47% for the voltage and 12.30% for the current. The simulation result concludes that the discussed optimized smart branch-based droop controller reduces drastically THD. Also, a separate study has been performed on the improvement of PQ by second proposed smart controller called as Photovoltaic Distribution Static Compensator (PV-DSTATCOM) grid-tied system using an adaptive reweighted zero attracting (RZA) control algorithm with perturbation and by applying maximum power point tracking technique (MPPT) for a three-phase system. The converter with PV array along with an active filter feature known as PV-DSTATCOM is required to convert the DC voltage into AC and for the improvement of the PQ by limiting harmonic distortions. It is concluded from the simulation results that the use of the RZA strategy presents an excellent steady state and transient response. The proposed PV grid-tied system is capable of working round the clock for both constant and variable irradiation and linear loads. The system is termed as smart as it can perform both modes automatically sensing the PV power and is capable of multi-directional power flow. The proposed method performs dual functions of improving PQ by working as DSTATCOM and also transfers power to the load and the grid obtained from PV array.
Parallel iterative finite-element algorithms for the Navier–Stokes equations with nonlinear slip boundary conditions
Authors: Zhou Kangrui , Shang Yueqiang 
Published: September 2020

Abstract
Based on full domain partition, three parallel iterative finite-element algorithms are proposed and analyzed for the Navier–Stokes equations with nonlinear slip boundary conditions. Since the nonlinear slip boundary conditions include the subdifferential property, the variational formulation of these equations is variational inequalities of the second kind. In these parallel algorithms, each subproblem is defined on a global composite mesh that is fine with size h on its subdomain and coarse with size H (H ≫ h) far away from the subdomain, and then we can solve it in parallel with other subproblems by using an existing sequential solver without extensive recoding. All of the subproblems are nonlinear and are independently solved by three kinds of iterative methods. Compared with the corresponding serial iterative finite-element algorithms, the parallel algorithms proposed in this paper can yield an approximate solution with a comparable accuracy and a substantial decrease in computational time. Contributions of this paper are as follows: (1) new parallel algorithms based on full domain partition are proposed for the Navier–Stokes equations with nonlinear slip boundary conditions; (2) nonlinear iterative methods are studied in the parallel algorithms; (3) new theoretical results about the stability, convergence and error estimates of the developed algorithms are obtained; (4) some numerical results are given to illustrate the promise of the developed algorithms.

Published: September 2020

Abstract
The current coronavirus disease 2019 (COVID-19) pandemic is impacting on food systems and has exposed the poor state of food security and lack of food system infrastructures. Consequently, sub-Saharan Africa countries face the compounded risk of COVID-19 and hunger. The syndemic will pose serious challenges for achieving food security imperatives of the Sustainable Development Goals (SDGs) by 2030. This article discusses the dynamics of food security imperatives brought about by COVID-19 pandemic. It examines the mitigating efforts of sub-Saharan African governments in addressing COVID-19 and how this effort impacts the attainment of SDGs One, Two, Three and 12. It finds that while the pandemic provides an opportunity for governments to strengthen their commitments, it raises questions on the ambitious global efforts to deliver SDGs by 2030. It recommends that African governments need to maximize intra-African trade with investments in agricultural biotechnological infrastructure in order to close the gap between the targets and the realities, in the efforts towards achieving the SDGs.
Gewaltsame Erziehung und ihre Folgen im Altersverlauf
Authors: Bentrup Christina 
Published: September 2020

Zusammenfassung
Die Forschungsergebnisse zum Ausmaß elterlicher physischer Gewalt gegen die eigenen Kinder zeigen seit Jahren ein eindeutiges Bild: Ein Großteil der Kinder in Deutschland erlebt Gewalt durch die Eltern. Es gibt jedoch Unterschiede in der Häufigkeit und Schwere. In diesem Aufsatz wird für Deutschland erstmalig die Entwicklung elterlicher Gewalt vom Kindes- bis ins frühe Erwachsenenalter analysiert. Anhand von Paneldaten aus dem Projekt »Kriminalität in der modernen Stadt« (Crime in the modern City, CrimoC) zeigt sich, dass trotz der Abschaffung des elterlichen Züchtigungsrechts 75 % der Befragungsteilnehmer und -teilnehmerinnen berichteten, Opfer physischer Sanktionen durch die Eltern geworden zu sein. Darüber hinaus verdeutlichen die Ergebnisse, dass gewaltsame Erziehung zwischen dem 13. und 15. Lebensjahr am verbreitetsten ist und bis zum frühen Erwachsenenalter weniger wird, aber nicht aufhört. Zudem gibt es einen starken Zusammenhang zwischen der Schwere und Häufigkeit elterlicher Gewalt gegen Kinder. Negative Folgen insbesondere von gewaltsamer Erziehung in der Kindheit erstrecken sich von einem erhöhten Risiko delinquenten Verhaltens über Gewaltdelinquenz, Drogenkonsum, weiterer Viktimisierung, erhöhter Gewalt- und geringerer Normakzeptanz. Die Herausforderungen, die diese Ergebnisse für den öffentlichen Umgang mit elterlicher Gewalt bedeuten können, werden diskutiert.
Die Prognose des Behandlungserfolgs einer Unterbringung gemäß § 64 Strafgesetzbuch – methodische (Selbst-)Kritik und Neuausrichtung
Authors: Querengässer Jan , Schiffer Boris 
Published: September 2020

Zusammenfassung
Eine Unterbringung in der Entziehungsanstalt gemäß § 64 Strafgesetzbuch (StGB) darf nur dann angeordnet werden, wenn eine hinreichend konkrete Aussicht auf einen Behandlungserfolg besteht. Als solcher gilt primär die Straffreiheit nach Entlassung aus dem Maßregelvollzug. Ungeachtet der Forderung nach einer dezidiert positiven Behandlungsprognose und anderer Eingangsvoraussetzungen, steigen die Einweisungszahlen in die Entziehungsanstalten gemäß § 64 StGB jedoch weiter an. Trotz eines in den letzten Jahren zunehmenden empirischen Forschungsinteresses, gelang es überdies nur bedingt, brauchbare Prädiktoren zur Prognose des Behandlungserfolges zu ermitteln. Dies liegt vor allem an den methodischen Einschränkungen, mit denen sich empirische Studien im Maßregelvollzug immer konfrontiert sehen, aber auch an den Besonderheiten der zumeist untersuchten Erfolgskriterien: Entlassart sowie Legalbewährung und Suchtmittelkonsum nach der Entlassung. Der vorliegende methodisch orientierte Beitrag setzt sich (selbst-)kritisch mit den bisherigen Forschungsansätzen und -ergebnissen auseinander und skizziert die prospektive Untersuchung der Gefährlichkeitsentwicklung von Untergebrachten gemäß § 64 StGB als einen Alternativansatz zur Ermittlung behandlungsprognostisch relevanter Prädiktoren.
The Rabi problem with elliptical polarization
Authors: Schmidt Heinz-Jürgen 
Published: September 2020

Abstract
We consider the solution of the equation of motion of a classical/quantum spin subject to a monochromatical, elliptically polarized external field. The classical Rabi problem can be reduced to third-order differential equations with polynomial coefficients and hence solved in terms of power series in close analogy to the confluent Heun equation occurring for linear polarization. Application of Floquet theory yields physically interesting quantities like the quasienergy as a function of the problem’s parameters and expressions for the Bloch–Siegert shift of resonance frequencies. Various limit cases are thoroughly investigated.
A basic definition of spin in the new matrix dynamics
Authors: Singh Tejinder P. 
Published: September 2020

Abstract
We have recently proposed a new matrix dynamics at the Planck scale, building on the theory of trace dynamics. This is a Lagrangian dynamics in which the matrix degrees of freedom are made from Grassmann numbers, and the Lagrangian is trace of a matrix polynomial. Matrices made from even grade elements of the Grassmann algebra are called bosonic, and those made from odd grade elements are called fermionic. In the present article, we provide a basic definition of spin angular momentum in this matrix dynamics, and introduce a bosonic(fermionic) configuration variable conjugate to the spin of a boson(fermion). We then show that at energies below Planck scale, where the matrix dynamics reduces to quantum theory, fermions have half-integer spin (in multiples of Planck’s constant), and bosons have integral spin. We also show that this definition of spin agrees with the conventional understanding of spin in relativistic quantum mechanics. Consequently, we obtain an elementary proof for the spin-statistics connection.

Combatting the Illegal Antiquity Trade through Museums and Economic Reform
Authors: Williams Lindsay 
Published: September 2020

The issues surrounding the illegal antiquity trade in Jordan are extremely complex. Many Jordanian looters are unaware of the economic disparity they are experiencing on the the antiquity market, or simply feel they are not in a position to do anything about it. These looters are searching for a way to support themselves and their community, and are either unaware or do not care about the damage the illegal antiquity trade has on the archaeological record. One of the easiest ways to communicate these issues to the Jordanian public is utilizing museums. However, this is only the first step as looters must be able to find a viable alternative to the loss of looting as a source of income. In this paper I will provide an explanation on the harmful effects of looting, both for the archaeological record and for looters, and offer more in-depth solutions to combat the illegal antiquity trade in Jordan.
How Restorative Justice Practices Create Safer More Caring School Communities
Authors: Streight Sage 
Published: September 2020

This paper looks at the traditionally retributive paradigm that is used in Western educational systems to control misbehaviour, issues of injustice, and violence in schools. The paper first talks about the ineffectiveness of this paradigm in creating communities of care and safer schools. The paper then offers that restorative justice (RJ) practices are more effective at creating communities of care and making schools safer. In fact, many schools in North America have been recognizing this and thus implementing RJ practices. The paper looks in depth as to what RJ is and how it is relevant to and works within the school context. This is done to show that RJ changes how individuals view harm. The traditional retributive paradigm views harm as an act of injustice against the state/law, whereas RJ views harm as harm against human beings. This means that RJ fosters understanding, accountability, empathy, connection, and learning positive reconciliation skills that can both be reactive and preventive ways to address harm in schools. Through all these things RJ looks to address the root causes of harm and attend to unmet needs that result from a specific harmful action.
These findings are important in the paper as they provide an understanding as to why RJ is then relevant in schools. The paper goes on to argue that RJ is relevant in schools because schools are tasked with socializing children, provide behaviour management, and are currently places where violence frequently occurs. These three factors are extremely important in shaping how individuals and communities operate. Because of this, RJ is argued to be necessary and relevant in order to ensure positive and constructive measures. Next, the paper looks at what circles are and how using circles as an RJ practice in schools can create constructive dialogue that leads to understanding that can reduce incidents of harm and injustice and help to develop communities of care. A study by Ortega, Lyubansky, Nettles, & Espelage (2016) is presented to support these findings.
Furthermore, the paper presents how circles could realistically and effectively be implemented in schools according to Braithwaite (2001). Circles need to be implemented on a school wide level, accessible to everyone, and with the hope that they become an everyday practice for individuals to use to resolve issues of harm and injustice. The paper concludes by reiterating that using circles as an RJ practice creates broader participation in schools and fosters a collective value and stake in what happens within a school. This is done through the intentional dialogue of circles, which is proven to foster community, understanding, and needs being met. Ultimately, this makes schools operate in a more responsible way where individuals look out for how their actions are affecting those around them, ultimately making them more conscious citizens and the school a safer place.
