Non-binary Spin Wave Based Circuit Design
Authors: Mahmoud Abdulqader , Vanderveken Frederic , Ciubotaru Florin , Adelmann Christoph , Hamdioui Said , Cotofana Sorin
Published: May 2022

By their very nature, Spin Waves (SWs) excited at the same frequency but different amplitudes, propagate through waveguides and interfere with each other at the expense of ultra-low energy consumption. In addition, all (part) of the SW energy can be moved from one waveguide to another by means of coupling effects. In this paper we make use of these SW features and introduce a novel non Boolean algebra based paradigm, which enables domain conversion free ultra-low energy consumption SW based computing. Subsequently, we leverage this computing paradigm by designing a non-binary spin wave adder, which we validate by means of micro-magnetic simulation. To get more inside on the proposed adder potential we assume a 2-bit adder implementation as discussion vehicle, evaluate its area, delay, and energy consumption, and compare it with conventional SW and 7nm CMOS counterparts. The results indicate that our proposal diminishes the energy consumption by a factor of 3.14x and 6x, when compared with the conventional SW and 7nm CMOS functionally equivalent designs, respectively. Furthermore, the proposed non-binary adder implementation requires the least number of devices, which indicates its potential for small chip real-estate realizations.
Generation of Coupling Topologies for Multi-Agent Systems using Non-Cooperative Games
Authors: Kloock Maximilian , Dirksen Matthis , Kowalewski Stefan , Alrifaee Bassam
Published: May 2022

This paper presents a method for generating coupling topologies for multi-agent systems. Our method is based on a non-cooperative game in which each agent chooses couplings to activate or deactivate using a utility function. The utility function measures the importance of agents to one another and enables conflict avoidance in distributed decisionmaking. Depending on the application’s needs, our method is able to generate unidirectional or bidirectional couplings. In our evaluation, we used car-like robots in a simulation environment. It shows that the generated coupling topologies are applicable to the domain of networked and autonomous vehicles.

Published: May 2022

This paper presents an approach for allocation of resources in an automotive service-oriented software architecture. Using mathematical optimization, we assign computational resources of an automotive compute cluster to a set of software services. Additionally, scheduling parameters of services are optimized under the consideration of dependencies between data flows and computations within services. The optimization minimizes power consumption and the maximum execution times of critical effect chains in a multi-objective optimization problem. The evaluation investigates the achievable reduction in power consumption using an exemplary system. Furthermore, we demonstrate a sharp reduction in maximum execution times of effect chains that span multiple services and ECUs.

El primer artículo del presente número de la Revista Boletín Redipe pone de manifiesto la tensión, que cada vez sacude a la existencia, entre el mundo del consumo y el mundo de la vida; la erosión de este último por aquel. La cultura del consumo que hoy gravita como nunca jamás en las relaciones entre los seres humanos y de estos con la naturaleza, es agenciada por fuerzas que encuentran en ésta una manera de maximizar ganancias, productividades y rentabilidades que no se traducen en bienestar para todos, en igualdad de derechos y oportunidades, en cuidado del planeta, sino por el contrario en minimización inexorable del acceso de todos a los bienes más elementales que se requieren para vivir con dignidad, se traduce en amenaza inminente para el futuro de la humanidad y de la vida, en posibilidad real de autoextinción. El orden del consumo impone la creencia de que el mundo del mercado constituye el motor del mundo de la vida. Como lo hemos expresado en otros momentos: el mundo del mercado no es el mundo de la vida.

Es este un desafío insalvable para la educación, que le impone redireccionar su curso, su apuesta por generar escenarios para que el hombre, en lugar de aposentarse en la cima del planeta, del mundo de la vida, desarrolle una consciencia reflexiva y actuante hacia la vida, hacia el tejido de naturaleza y vida, de mundo común. Para decirlo con Mínguez, R. (2022), “es preciso reorientar el sentido de la educación hacia una forma de vida sostenible”, en el marco de una ética y una práctica otras, de una ética y actividad educativa por los negocios, a una ética y educación por la vida. Una educación que haga de la actividad de enseñar, aprender y formar una posibilidad de pensar sintiendo, para decirlo con Rodríguez; M. E, (2022 ), en el contexto de la matemática, “el sentipensar como forma matemática de expresarse a la luz de la emotividad del estudiante”, o con Lopera, C.P, (2022), “la necesidad de tener maestros y maestras alegres y empáticos, sobrepasando la mirada adultocéntrica que ha primado en las relaciones pedagógicas y sociales”. El sentido más entrañable de la educación precisa una ética del buen vivir y del vivir sabroso, con sentido de mundo común, en lugar de la ética de los negocios, del vivir bien particular con sentido fragmentario que hoy domina en la escolaridad y en la vida cotidiana.
On the eve of adversity: scientific works of universities and institutions of the USSR in 1941
Authors: Doiar Larуsa
Published: May 2022

This article raises the issue of research heritage accumulated in the USSR. This exploration is devoted to works published by teachers of Ukrainian universities and institutes that is 1941, that is shortly before Hitler's German attack on the USSR. Based on the elaborated generality of scientific periodicals of the Ukrainian SSR, the author claims that at that time the research of universities approached parity relations with the academic science of that time, significantly complementing the latter with research experience of both central and peripheral educational institutions. The article considers works from various scientific fields, which gives grounds to speak about the diversity of the development of Ukrainian Soviet science within the walls of higher educational institutions. The investigation is based on the materials of the State Archive of the Press of the Book Chamber of Ukraine named after Ivan Fedorov, in particular, continuing publications of the Kyiv State University named after T. G. Shevchenko, Kharkiv, Odessa, Cherkasy, Sumy and Kryvyi Rih state pedagogical institutes. Particular attention is paid to the collection of scientific works of the Kryvyi Rih STI, because the city of Kryvyi Rih, christened the "iron ore capital of Ukraine", except for a short (1923—1931) district status, has always been on the periphery, so the powerful development of local science, of course, impressive. The emotional factor of the reconnaissance is quite clear, based on the fact that the war started completely unexpectedly — university and institute teachers worked in the usual way, publishing their scientific works, literally, on the eve of the terrible disaster that befell the country. The most relevant statement of the author today is the 100% dominant Ukrainian language of scientific works of teachers of pre-war universities, which testifies to the success of the Bolsheviks' policy of Ukrainization of the Ukrainian SSR implemented in practice.
Ukrainian book prints 1945—1946: reflections on the events of the military disaster
Authors: Doiar Larуsa
Published: May 2022

The presented article raises the problem of the Second World War in the context of the events that took place on its main direction — the Eastern Front, where, without exaggeration, the fate of all mankind was decided. The racial doctrine of Hitler's Nazism left no chance for the physical existence of most peoples, who were treated by it as inferior and those who could only be in slavery. Thus, on May 9, 1945, perpetuated not only the victory of one military bloc over another, but also the right of the human community to its diversity and life in conditions of racial and national equality, tolerance, and humanism. This article is devoted to the problem of covering the events of the war in book prints published in the Ukrainian SSR shortly after its end. The purpose of the presented research was to conduct a content analysis of previously unused and now forgotten books of 1945—1946 editions published in the USSR and devoted to the war of 1941—1945. The study involved literature of various genres, publishing volumes and purpose, namely: official documents (state and party), scientific works, memoirs (memoirs, memoirs), epistolary, fiction and poetry. Realizing this goal, the author worked on book prints published in several publishers of the Ukrainian SSR at that time, in particular, the Ukrainian State Publishing House (State Publishing House of Ukraine), the Ukrainian Publishing House of Political Literature (Political Publishing House of Ukraine), the State Publishing House of Fiction (Lithuania), the publishing house of Odessa State University named after I. Mechnikov, the publishing house of the Dnipropetrovsk regional committee of the Communist Party of the Bolsheviks of Ukraine. Based on this work, the author came to the conclusion that the printing press of the first postwar years laid a solid foundation of a huge literary community, which for many decades determined the public attitude to the events of the Great Patriotic War.

Objective: Alternative treatment Cesarean section patients having general anesthesia and spinal anesthesia were compared for neonatal outcomes. Methods: This quasi-experimental study was conducted in the Department of Anaesthesia, Rajshahi Medical College Hospital, and Tertiary Hospital in Rajshahi, Bangladesh. From March 2018 to November 2020. During lower segment Cesarean sections, patients were admitted through the obstetric OPD. Patients were chosen at random via an envelope draw. There were 160 patients in all, split equally into two groups for analysis. Patients in Group A (n=80) received spinal anesthesia, whereas those in Group B (n=80) received general anaesthetic. Umbilical artery blood was drawn shortly after the newborn's birth to measure the pH of the blood. At 0 and 5 minutes, the APGAR score was evaluated and recorded on a proforma. If the APGAR score was 7 or higher, and the blood pH was 7.2 or above, anesthesia was deemed successful, i.e., acceptable. Results: The total amount of neonates in group A with an APGAR score > 7 was 78 (97.5 %) whereas in group B it was 60 (75 %) and 74 (92.5 %). More neonates in group A had an APGAR score greater than 7 than in group B (p =0.028). Additionally, group A's average Apgar score at 0 minutes was higher than group B's at both 1 and 5 minutes (p=0.0001) B; 8.04±0.82 vs 7.10±0.92 (p=0.0001) and 9.89±0.32 vs 9.34±1.07 respectively (p=0.0001). Umbilical artery blood pH>7.2 was observed significantly high in group A93.8% as compared to group B 83.8% (p=0.045). Also, average pH was significantly high in group A than group B e.g., 7.38±0.15 vs 7.21±0.16 (p=0.017). Conclusion: In interventional Cesarean sections, spinal anesthesia has a better neonatal outcome than general anaesthetic.

Malignant schwannomas are rare types of malignant peripheral nerve sheath tumors composed of neoplastic Schwann cells. Many are discovered incidentally as solitary tumors. The cause is unknown. Most develop independently, although some are associated with genetic disorders such as neurofibromatosis type 2 or schwannomatosis. Schwannomas can emerge in any part of the body. They affect all age groups, with a peak occurrence between 25 and 40, without predilection to sex or race. Many are asymptomatic; nevertheless, symptoms such as paresthesia and pain are induced by mass effect and direct nerve invasion. A thorough physical examination, imaging modalities such as magnetic resonance imaging, and surgical biopsy are used to make a diagnosis. Treatment is affected by several parameters, such as the location of the tumor and the severity of the symptoms. Asymptomatic patients are treated conservatively, whereas those who are symptomatic undergo surgical resection with a favorable prognosis.
Balloning Osteolysis around Acetabular Component on Long Term Follow-Up in 15 Years Old Total Hip Arthroplasty (THA) Using Proxima Short Femur Stem: A Case Report
Authors: Mahajan Dr. Neetin P , Patil Dr. Tushar C , Jain Dr. Kevin A
Published: May 2022

Introduction: In developed countries, cementless THA is the hip replacement procedure of choice, taking over cemented THA. The uncemented THA necessitates the need of snugly fitting long femur stem which can later lead to thigh pain and proximal stress shielding seen in stems loading in diaphysis. Long conventional femur components carry risk of intra and early perioperative fracture risk upto 2.5% and incidence of thigh pain upto 11%. These issues can be avoided by preserving bone stock with the use of short metaphyseal femur stem that fix at metaphyseal cancellous bone. These proxima stems load femur metaphysis more physiologically and can be inserted in a minimally invasive way. Case report: Here we present a long term follow-up of 15 years of an operated case of left hip THA done using short proxima stem of DePuy in a 41 years old male suffer from left hip osteonecrosis. At 15 years, there was ballooning periacetabular osteolysis and loosening of acetabular cup. Conclusion: Short metaphyseal proxima stem of DePuy is a good alternative in uncemented THA, especially in young adults required hip replacement surgery due to debilitating hip disorder, giving similar survival rates when compared with conventional long femur stem. This provides advantage of being minimally invasive, less soft tissue damage, less stress shielding with more physiological load distribution and preserving bone stock. The revision replacement surgery that will be required eventually in future can be better managed due to preserved bone stock and soft tissue.

Computer Graphics is a part of computer science that deals with the creation and manipulation of (visual) images digitally. A simple form of computer graphics is 2D computer graphics which later evolved into 3D computer graphics, image-based (image processing), and pattern recognition (pattern recognition). Computer graphics are often also known as data visualization. Graphics include images and other imagery generated by the computer in the form of lines. OpenGL (Open Graphics Library) is an API standard that can be used to create graphics-based applications, both two-dimensional (2D) and three-dimensional (3D). OpenGL is cross-platform, meaning that it can be run on various operating system platforms that exist today. using OpenGL, we first need a conception of the interface in its implementation of object protection. One method that is commonly used is to create a window-based OpenGL. To be able to conceptualize windowing in OpenGL, we need a certain tool. What we are using this time is GLUT (OpenGL Utility Toolkit).

Garbage is one of the causes of a problem that is difficult to solve in Indonesia and even in other countries, many cities in Indonesia are filled with garbage. Maybe one of the factors is the scattering of garbage everywhere because humans themselves are lazy to throw away their place or are already accustomed to littering, causing rubbish to be scattered everywhere which can eventually lead to garbage pollution, unpleasant odors and ultimately can cause flooding. In this research, we will make a tool for sorting organic and inorganic waste, namely by making a tool such as a conveyor to sort the types of organic waste and the types of inorganic waste which will later be classified separately and collected in their own place so that they are not mixed together. To distinguish which organic and inorganic waste we will use a capacitive proximity sensor as a sorter, atmega 16 as a microcontroller to run all the work of the appliance system. DC motor as a conveyor drive. The LDR sensor detects the presence of waste. From the test, the organic and inorganic waste sorting tool has pretty good results with an average success rate of detecting organic waste of 66.67% and the success rate for inorganic waste is 63.33%.

The Covid-19 pandemic that hit Indonesia forced the Indonesian population to be ready with a new normal order. With this condition, it is hoped that the community can implement changes to the new order of life by implementing health protocols. But nowadays, people often violate health protocols, physical distancing, which is one form of prevention in the new normal era. The innovation of a Raspberry Pi-based tool designed to produce warnings for physical distancing violations is expected to minimize violations. The camera installed on the system will help detect the distance between two or more people and will give a warning to immediately carry out physical distancing if the measured distance is less than 1 meter. The purpose of writing this research is to design a system and concept of "Preventive Efforts for the Spread of Covid-19 Through a Raspberry Pi-Based Distance Monitoring System". The method of writing this article uses the concept of a literature study involving several studies and scientific findings in the form of secondary data from research results that have been published in scientific journals. From the results of the tests that have been carried out, it is known that the tool has succeeded in detecting physical distancing violations between two or more people. After the tool can detect a violation, the tool emits a warning sound to inform the violation that has occurred. From the result, it can be concluded that this system proposed can run well as expected.

A poluição sonora é um dos tipos de poluição mais presentes nos aglomerados urbanos, onde o ruído acima de padrões estabelecidos por instituições com a OMS torna-se capaz de gerar diversos efeitos nocivos aos indivíduos e sua manifestação ocorre tanto nas esferas física, psicológica e social, interferindo diretamente na comunicação estabelecida entre as pessoas e demais seres vivos em função da propagação as ondas de pressão sonora. A propagação desse tipo de poluição e incomodo também pode ser gerada nos templos religiosos, onde muitos não possuem proteção acústica adequada para a realização das suas atividades. O uso comum de microfones de alta capacidade para maior alcance sonoro e instrumentos musicais eletrônicos de alta intensidade como guitarras, violões elétricos, órgãos elétricos e bateria acoplados a de caixas acústicas de alta potência constitui-se nessa principal fonte sonora. Conforme os vizinhos reclamantes dessas instituições religiosas, o som elevado nos momentos de culto torna-se bastante inconveniente e perturba o sossego de todos. Segundo os moradores residentes ao entorno dos templos religiosos, o momento das celebrações é praticamente impossível realizar atividades simples como ver televisão, ouvir música, dormir, entre outras atividades. A necessidade de análise de impacto de vizinhança referente à produção do Ruído é extremamente importante para a concepção de um ambiente residencial hígido, independente do gerador do agente físico nocivo. O Estudo de Impacto de Vizinhança é uma ferramenta muito importante e capaz de analisar e informar previamente à gestão municipal quanto às repercussões da implantação de atividades impactantes privadas ou públicas, em áreas urbanas, a partir da ótica da harmonia entre os interesses particulares e o interesse da coletividade de modo a evitar desequilíbrios.
