Building a Leader Framework for Post-Pandemic Response Expertise for Higher Education Future Reality
Authors: Makina Antonia 
Published: September 2024

A successful future for higher education is dependent on the level of preparedness to manage future crises that are no longer linear processes in the best way possible. The severe disruption of academic progress post-COVID-19 across the globe brought a growing sense of chaos in the education system. This forced education institutions to adopt a rapid re-design of institutional strategic systems that called for different kinds of responses in different contexts because previous successful leadership approaches often fail in crisis situations. However, the challenges brought about by the chaos have positively presented humanity with many opportunities to re-think and re-engineer a new way of doing business. Therefore, this paper designs and develops a post-pandemic conceptual model that is an approach to crisis management, quick decision-making, and quick problem-solving to enable general adaptation to future pandemics.
Through a developmental research design and a comprehensive literature review, an adaptive emergence response cycle (AERC) was developed and built around the theory of chaos, the reflective practitioner theory, using the adaptive approach. One potential benefit of the post-pandemic response model was the creation of an emergency response equation that was best suited for the post-pandemic crises. This model allows higher education management to be protected by planning generalizable futuristic crisis models.

The purpose of this study is to determine the effect of deficit irrigation application on the growth of bell pepper plants and to assess the efficiency of irrigation water application for bell pepper plants. The design used in this research is a Completely Randomized Design with 4 levels of deficit irrigation treatments and six replications. The procedures involved in this study include analysis of soil moisture to determine field capacity and permanent wilting point, treatment conditioning, planting, plant maintenance, observations, and finally, harvesting. The data obtained were tested for homogeneity of variances using the F-test, and if there were differences among treatments, further analysis was conducted using the Least Significant Difference test at the 5% level. The results of the data analysis are presented in tables, graphs, and diagrams. Deficit irrigation treatments significantly affected the plant height and leaf number parameters. The plant response to irrigation was limited under deficit irrigation based on total fruit weight, where bell pepper plants produced the best fruit under the 80% deficit irrigation treatment, with an average total fruit weight of 242.17 grams. Meanwhile, in the ID4 treatment, the plant results were less favorable due to stress. The response of the results to water (Ky) indicates that the Ky value (Ky <1) for bell pepper plants in the ID2, ID3, and ID4 treatments shows values less than 1, meaning that these treatments are tolerant to water stress.

This research aims to detect flood susceptibility using the Topographic Wetness Index (TWI) and create a flood susceptibility map in the Way Katibung Sub-watershed using the Topographic Wetness Index (TWI). This study employs the Topographic Wetness Index (TWI) method with observation parameters including land slope, soil type, land elevation, rainfall, and land use. The results show that the most influential parameter on the Topographic Wetness Index (TWI) is the land slope. Therefore, TWI can be used to detect flood susceptibility in the Way Katibung Sub-watershed, which is predominantly flat. Areas with the lowest average TWI value of 6.35 have no potential for flooding, whereas areas with average TWI values of 10.94 and 13.95 are the most susceptible to flooding. The flood-prone areas are primarily located near river streams, such as Mekar Sari, Sumber Agung, Talang Way Sulan, Karang Pucung, Banjar Sari, Purwodadi, and Pamulihan in Way Sulan District.

Drought is a routine case of natural disasters. Drought in a region can disrupt human activities. Drought occurs due to reduced rainfall, temperatures that are too high than normal, low soil moisture and insufficient surface water supply. The aim of this research is to obtain the distribution of rain and analyze the drought value index in the Bandar Lampung area. The cause of this drought is a step to predict the drought that will occur by analyzing the rain and temperature. This analysis is done by calculating the water balance and determining the drought level using drought index table by thorthwaite mather. The drought analysis is conducted in Bandar Lampung area, where the Bandar Lampung area is the capital city of Lampung province with an area of ± 160 km2 with an average population density of 8,316 people/km2. From the Drought Value Index, the level of drought in the Bandar Lampung area is predominantly low and the level of drought is moderate in the Peace District area.

Formation of capillary-gravity waves in the flow under the influence of a system consisting of two vortices

Published: September 2024

На основании метода, предложенного Келдышем, изучен случай образования волновых движений на поверхности идеальной однородной бесконечной жидкости, когда под поверхностью жидкости на конечной глубине помещен вихревой симметричный диполь. В рамках двумерной задачи рассматривалась плоская бегущая волна синусоидальной формы, в которой каждая ее частица будет двигаться по окружности, расположенной в вертикальной плоскости, то есть центр окружности будет совпадать с направлением распространения волны. В качестве источника возмущений выбран не одиночный вихрь, а волновой диполь. Получены два асимптотических решения для профиля волны на свободной поверхности: профиль капиллярно-гравитационных волн до источника возмущений, где ключевую роль в формировании волновых возмущений играет поверхностное натяжение; профиль капиллярно-гравитационных волн после источника возмущений, при формировании которого доминирующей является сила тяжести. Показано, что при разложении асимптотических решений в ряд Тейлора для профиля волны на свободной поверхности, для капиллярно-гравитационных волн характерны следующие закономерности: при сравнительно небольших расстояниях от источника возмущений профиль волны фактически линейный, приближения не вносят существенного влияния, то есть волна стремиться к предельной форме; но, по мере удаления от волнового диполя начинает формироваться синусоидальный профиль волны. На формирование профиля волны оказывает влияение изменение глубины источника возмущения. Так, например, при уменьшении h в капиллярно-гравитационной волне преобладает капиллярная составляющая, а при увеличении h более весомый вклад вносит гравитационная составляющая.
Capillary-gravity waves significantly change the general circulation of the water surface of the World Ocean: attenuation and collapse of longer waves, gas exchange and mixing in the upper layer, kinematics of surface suspensions, and, therefore, require additional study. In the framework of a twodimensional problem, the paper considers surface capillary-gravity waves without taking into account wind effects, but taking into account the isobaric approximation. The approach proposed by Keldysh is chosen as a quantitative basis. The object of perturbation located at a finite depth is a vortex dipole with constant curl. Two asymptotic solutions were obtained on the basis of analytical calculations: the first solution describes the profile of capillary-gravity waves located behind the vortex dipole; the second solution is the profile of capillary-gravity waves in front of the perturbation source. It is shown that the capillary component of the wave dominates in the formation of waves in front of the perturbation source, and the gravitational component dominates behind the obstacle. The relations between isobaric and barotropic effects on the free surface are qualitatively analyzed. The case for the gravitational component is considered; for this purpose, the technique of representing the wave profile using a Taylor polynomial was used
Mathematical Model of Van der Pol-Airy Fractional Oscillator
Authors: Салимова А.И. , Паровик Р.И. 
Published: September 2024

В работе предложена математическая модель нелинейного осциллятора Ван дер Поля-Эйри с учетом наследственности. Нелинейность осциллятора обусловлена наличием зависимости коэффициента трения от квадрата функции смещения, что характерно для осциллятора Ван дер Поля. Также собственная частота колебаний представляет собой функцию от времени, которая линейно возрастает при его возрастании. Последнее характерно для осциллятора Эйри. Эффекты наследственности вводятся в модельное уравнение посредством дробных производных в смысле Герасимова-Капуто. Они указывают на то, что колебательная система может обладать эффектами памяти, которые проявляются в зависимости текущего ее состояния от предыдущих. Для предложенной математической модели был разработан численный алгоритм, основанный на явной конечно-разностной схемы первого порядка. Численный алгоритм был реализован в компьютерной программе на языке Maple, с помощью которой была произведена визуализация результатов моделирования. Были построены осциллограммы и фазовые траектории при различных значениях параметров модели. Показано, что дробная математическая модель может обладать различными колебательными режимами: от автоколебательных, затухающих и хаотических. Дается интерпретация результатов моделирования.
The paper proposes a mathematical model of the nonlinear Van der Pol-Airy oscillator taking into account heredity. The nonlinearity of the oscillator is due to the dependence of the friction coefficient on the square of the displacement function, which is typical for the Van der Pol oscillator. Also, the natural frequency of oscillations is a function of time, which increases linearly as it increases. The latter is typical for the Airy oscillator. Heredity effects are introduced into the model equation through fractional derivatives in the Gerasimov-Caputo sense. They indicate that the oscillatory system may have memory effects that manifest themselves depending on its current state from previous ones. For the proposed mathematical model, a numerical algorithm was developed based on an explicit first-order finite-difference scheme. The numerical algorithm was implemented in a computer program in the Maple language, with the help of which the simulation results were visualized. Oscillograms and phase trajectories were constructed for various values of the model parameters. It is shown that a fractional mathematical model can have various oscillatory modes: from self-oscillatory, damped and chaotic. An interpretation of the simulation results is given
Задача управления для уравнения теплопроводности с граничным условием Неймана

Previously, boundary control problems for a heat conduction equation with Dirichlet boundary condition were studied in a bounded domain. In this paper, we consider the boundary control problem for the heat conduction equation with Neumann boundary condition in a bounded one-dimensional domain. On the part of the border of the considered domain, the value of the solution with control parameter is given. Restrictions on the control are given in such a way that the average value of the solution in some part of the considered domain gets a given value. The studied initial boundary value problem is reduced to the Volterra integral equation of the first type using the method of separation of variables. It is known that the solution of Volterra’s integral equation of the first kind cannot always be shown to exist. In our work, the existence of a solution to the Volterra integral equation of the first kind is shown using the method of Laplace transform. For this, the necessary estimates for the kernel of the integral equation were found. Finally, the admissibility of the control function is proved.
Ранее были исследованы задачи граничного управления для уравнения теплопроводности с граничным условием Дирихле в ограниченной области. В данной работе рассматривается задача граничного управления для уравнения теплопроводности с граничными условиями Неймана в ограниченной одномерной области. На части границы рассматриваемой области задано значение решения с управляющим параметром. Ограничения на управление задаются таким образом, чтобы среднее значение решения в некоторой части рассматриваемой области получало заданное значение. Исследуемая начально-краевая задача сводится к интегральному уравнению Вольтерра первого типа с использованием метода разделения переменных. Известно, что не всегда можно доказать существование решения интегрального уравнения Вольтерра первого рода. В нашей работе существование решения интегрального уравнения Вольтерра первого рода показано с помощью метода преобразования Лапласа. Для этого были найдены необходимые оценки ядра интегрального уравнения. Наконец, допустимость функции управления доказана.
LA TUTELA DELLA SALUTE E SICUREZZA SUL LAVORO ALLA PROVA DELLA RIVOLUZIONE DIGITALE
Authors: Bassotti Martina 
Published: September 2024

I cambiamenti in atto nelle modalità di organizzazione ed esecuzione della prestazione lavorativa incidono inevitabilmente sulla tutela della salute e sicurezza del lavoro. L’affermarsi nei contesti lavorativi di tecnologie avanzate come l’intelligenza artificiale unitamente alla diffusione del lavoro svolto da remoto e/o organizzato tramite piattaforme digitali, ha comportato l’emersione di rischi per salute “più striscianti” rispetto a quelli tipici della società industriale, che riguardano la sfera psicosociale del lavoratore. Il diritto deve, quindi, garantire strumenti a tutela della salute e sicurezza del lavoratore tenendo conto delle innovazioni tecnologiche e delle nuove modalità di esecuzione ed organizzazione delle prestazioni lavorative. In tale prospettiva, è necessario interrogarsi circa l’adeguatezza del quadro normativo di fronte ai nuovi rischi e alle nuove esigenze di tutela conseguenti all’impatto dell’evoluzione tecnologica sul mondo del lavoro.

Pode um juiz deixar de aplicar um precedente judicial por considerá-lo injusto ou insensato? Esta recusa importa em desobediência civil por parte do magistrado? Sendo a desobediência civil espécie de protesto que integra o chamado direito de resistência, a hipótese que se investiga é se, e em que condições, o descumprimento de precedentes vinculantes por magistrados brasileiros poderia configurar desobediência civil. Trata-se de estudo bibliográfico e analítico que aborda desobediência civil e hipóteses de sua aplicabilidade no direito brasileiro, seguida da investigação de bases da doutrina dos precedentes nos sistemas common law e civil law e sua recepção no ordenamento pátrio. A análise conduz à conclusão da impossibilidade de o juiz invocar a desobediência para descumprir precedente vinculante, por ausentes no exercício funcional da magistratura as condições exigidas para a caracterização da desobediência civil.
