Essays on Two-Sided Matching with Contracts
Authors:   , Ripperger-Suhler Daniel Aaron , Serfes Konstantinos
Published: August 2022

This dissertation consists of three chapters that examine contracting problems in two-sided matching models. The first chapter studies use of syndication contracts in the venture capital matching market, and the resulting impact on portfolio company outcomes. A novel empirical model is developed to account for endogeneity issues due to matching between venture capitalists (VCs) and companies as well as the simultaneous causality bias coming from contract choice. The estimates show that unobserved company heterogeneity can lead to biased company outcome estimates, which can change over time due to changes in preferences over unobserved company characteristics. The second chapter, joint with Kaniska Dam and Konstantinos Serfes, explores the effect of incentives on choice of organizational structure, and the implications for the output distribution in two-sided matching model. A novel condition guaranteeing positive assortative matching (PAM) is derived for two-sided matching models with non-smooth bargaining frontiers. In the model, the choice between integrating and remaining separate results in a non-differentiable bargaining frontier and produces equilibria in which some matched pairs integrate, and others do not integrate. These equilibria produce drastically different output distributions and provide researchers with predictions that can be tested empirically. The final chapter considers a principal-agent model in which the agent can choose and exclusive contract with a single principal, or a non-exclusive contract with two principals at the cost of additional effort. The two-sided matching model shows that the endogenous outside option absent in a standard principal-agent model is necessary in order to generate certain equilibrium contract patterns. Finally, the model shows that changes in the costliness of additional effort by the agents has a non-monotonic impact of agent utility.

Authors: Çınar Rıdvan Fırat , Kocadağ Fatih , Demirkol Aşkın
Published: August 2022

In this study, a useful method for synthesizing range profiles to be used in ultra-wideband radar operations is discussed. One-dimensional transmission-reflection geometry of the radar scenario, which consists of a single receiver and single transmitter, is formulated by using the Green’s function. A one-dimensional time domain Green’s function is employed in the formulation and the impulsive characteristic of this function, which provides focus on the target position, has been determined. This characteristic represents the impulse response of the propagating medium to the electromagnetic wave. The resulting derivation offers a framework that can also be used in higher dimensional and complex radar problems by taking the advantage of its flexibility. Proposed method has been detailed and tested on an exemplary implementation and successful results that provide good focus on the target positions are shown in the conclusions. Finally, outcomes and benefits are discussed.

Authors: Gaviria-Pinzon Jorge , Ruiz Giancarlo , Garcia Maria Paula , Gutierrez Carlos David , Bermudez Luis Eduardo
Published: August 2022

The use of stereolithographic models and virtual planning in plastic surgery have been used mainly in craniomaxillofacial reconstructions secondary to trauma, oncological reconstructions, orthognathic surgery and correction of craniofacial developmental anomalies of craniofacial development, among others, making surgical planning a less tedious process and reducing surgical time. In this article we present the experience using this technology in a referral center. Eight cases are exposed where the different applications of virtual planning and 3D models can be evidenced. Pre-op and post-op images are presented showing the similarity with the planning. We have implemented its use not only for facial trauma reconstructions with free flaps, but also for the correction of sequelae, correction of complex craniofacial abnormalities, oncological defects, and hand reconstructions. Our experience has been favorable since it allowed us to obtain satisfactory functional and predictable results and a reduced surgical time, especially in complex cases. If available, this technology should be considered as a useful tool to obtain predictable and reliable results.

Authors: Gilani Mohamad Azhar , Ain Syed Najmul
Published: August 2022

Background: Menopause brings with it a cluster of symptoms and health problems. Low back ache (LBA) decreases the quality of life both socially and economically by increasing sickness absenteeism. Women are more likely to have backache and more so after menopause. Objective of the study was to find out the prevalence of LBA among postmenopausal women and also to assess the severity of the LBA.

Methods: This was a cross-sectional community-based study conducted in block Hazratbal of district Srinagar, the field practice area of the department of community medicine, Government Medical College (GMC), Srinagar. The data was collected over a period of 3 months in 2018 by consecutive sampling by going door to door in the area. A woman who had attained menopause as per the definition was included in the study.

Results: A total of 198 women were included. Mean age at the time of contact was 53.56 years. The prevalence of LBA among these women was 77.8% (154 of 198 women) with almost 55% women having moderate LBA and 16% women grading their LBA as severe. Those in late menopause were 4 times more likely to have severe LBA than those in early menopause.

Conclusions: The magnitude of LBA among postmenopausal women is huge. About one quarter of these women have severe LBA. Therefore, to maintain a good quality of life of these women, specific measures to tackle this problem must be taken.

Cães e gatos convivem com humanos há milhares de anos e isso mostra o quanto eles são importantes. Esses animais são considerados membros da família, entretanto, a falta de conhecimento sobre suas necessidades fisiológicas, comportamentais e psicológicas por parte de seus tutores são fatores importantes para suas vidas, pois essa falta de conhecimento promove condições de alimentação inadequada, maus-tratos, proliferação de doenças, abandono e, consequentemente, superpopulação de animais nas ruas. A partir dessa problemática, foi realizado um estudo transversal, no período de outubro de 2018 a agosto de 2019, por meio da aplicação de um questionário para analisar o perfil socioeconômico de tutores de cães e gatos domiciliados na zona urbana da cidade de Patos, Paraíba, Brasil, e seu conhecimento sobre bem-estar animal, abuso e guarda responsável. Dos 270 entrevistados, 67% possuíam animais domésticos, sendo os cães os mais evidentes (p < 0,001). A maioria dos entrevistados – 85,6% (p < 0,001) – afirmou saber o que significa bem-estar animal. No entanto, 62,6% não responderam o que significa guarda responsável (p < 0,001). Assim, destaca-se a importância de tais estudos para verificar o conhecimento da população sobre o assunto objetivando a implementação de políticas públicas que visem minimizar os danos à vida animal.

Published: August 2022

O desenvolvimento de sistemas computacionais capazes de processar mais dados a custos cada vez menores tem estimulado o uso de softwares de modelagem tridimensional que permitem obter resultados gráficos cada vez mais realistas. Na robótica, simulações tridimensionais têm possibilitado o estudo de robôs de alto custo de aquisição, por meio de modelos computacionais que podem ser desenvolvidos em computadores pessoais, os quais são mais baratos e acessíveis. Nessa direção, o principal objetivo deste trabalho foi modelar computacionalmente um protótipo de robô móvel desenvolvido pelo Grupo de Pesquisa em Controle, Automação e Robótica (GPCAR) do IFPB – Campus Cajazeiras. O modelo computacional proposto pode ser utilizado tanto para testar algoritmos antes da implementação no robô real quanto para o ensino e a pesquisa em robótica móvel autônoma. A implementação computacional proposta neste trabalho foi realizada por meio do Autodesk Inventor e do Blender, em seguida, exportada para o ambiente de simulação do Gazebo. Além disso, o robô virtual foi integrado ao Robot Operating System (ROS). Resultados experimentais são apresentados para demonstrar o funcionamento do modelo computacional e sua integração com o protótipo desenvolvido, apontando a aproximação entre os resultados obtidos por meio do robô real e seu gêmeo digital.

Published: August 2022

Neste artigo é resolvido um problema conjugado condução-convecção externa, no escoamento laminar incompressível de um fluido newtoniano sobre uma placa plana, em regime permanente, com objetivo de mostrar o perfil de velocidade, temperatura e as camadas limites hidrodinâmica e térmica. As equações de momento e energia são transformadas usando mudança de variável para determinar as espessuras das camadas limites. Para resolver o problema acoplado foi necessário utilizar, no campo hidrodinâmico, a solução analítica exata da espessura da camada limite hidrodinâmica, enquanto no campo térmico foi utilizada a relação entre o número de Prandtl e a espessura da camada limite hidrodinâmica. As equações diferenciais parciais da quantidade de movimento e da energia são transformadas em equações diferenciais ordinárias através da técnica da transformada integral generalizada, que apresenta uma solução híbrida analítico-numérica, tornando possível determinar a espessura da camada limite hidrodinâmica sem utilizar o método de similaridade (solução de Blasius), o que mostra um tratamento inédito na resolução deste problema. A evolução da posição da camada limite hidrodinâmica foi calculada e comparada com soluções aproximadas, obtendo-se excelentes resultados. No campo térmico, variando os parâmetros adimensionais Prandtl e Reynolds, observou-se um comportamento inversamente proporcional à espessura da camada limite, conforme previsto na literatura.

Potential of Strawberry (Fragaria x annanasea) Extract as Whitening Agent for Discolored Teeth
Authors: Rachmawati Emma , Febriani Mirna
Published: August 2022

The Bleaching technique has long been applied in dentistry. Strawberry (Fragaria x annanasea) is a non-dental material that can be used for natural bleaching. The strawberries contain ellagic acid and malic acid which can whiten teeth. Other ingredients found in strawberries also have a low pH so they can whiten teeth better when compared to other fruits. Strawberries also give bad side effects, namely increased tooth sensitivity. This research aims to explain the potential of strawberry (Fragaria x annanasea) extract as a whitening agent against discolored teeth. Based on reference sources obtained from journals, textbooks, and websites accessed through the databases of Google Scholar, Science Direct, EBSCO, and PubMed (National Library of Medicine, Bethesda, MD, USA) and searched for the keywords “Bleaching, Strawberries (Fragaria x annanasea), and Discoloration.” The types of journals taken are scientific and descriptive journals published from 2010 – 2020 and dental material textbooks from 2010 – 2020. The research concludes that the use of strawberry (Fragaria x annanasea) fruit extract can provide a whitening effect on teeth that have changed color and is the best solution compared to synthetic tooth whiteners. In addition, strawberries also provide side effects, namely increased tooth sensitivity.
Two-parametric fracture criterion for Mode I crack
Authors: Pokrovskiy A.M. , Egranov M.P.
Published: August 2022

The study introduces a two-parametric criterion for maximum tangential stresses adapted to the Mode I crack, which includes T-stresses. The difference of this criterion is that the size of the fracture process zone is written with account for the T-stresses, while the tangential stresses in the fracture process zone are equated to the local strength of the material rather than to the ultimate strength, as it is usually done. The paper gives two-parametric fracture criteria for the case of plane stress and strain states, allowing the strain constraint along the crack front. Within the study, we obtained expressions for the effective stress intensity factor which include the T-stresses — ultimate strength ratio, in addition to the stress intensity factor. This expression allows us to determine the most dangerous point of the crack front and, provided we know the fracture toughness of the material, to estimate the crack resistance of the part with the crack. As an example of using the fracture criterion, we considered a semi-elliptical edge crack in a plate stretched in two directions.

Published: August 2022

Along with the designing configuration of spacecraft for various purposes, in parallel, the choice of the configuration and location of the systems ensuring thermal regime takes place. In such systems, in addition to the construction itself, depending on the target orbit and heat-generating equipment a huge number of different elements can be included, ensuring equipment temperature control and, if it is a manned spacecraft ensuring also the necessary requirements for maintaining a constant temperature and humidity in the pressurized compartment. Therefore, this article discusses autonomous elements of active and passive domestic thermal management systems currently used in the design of non-pressurized spacecraft. This will help in making the most correct technical solution when developing a spacecraft in terms of cost, reliability, durability and normal operation of the target onboard equipment.

Authors: Kazakov G.V. , Terentyev O.S.
Published: August 2022

The paper considers a set of methods and algorithms that allows determining the geodetic coordinates of the vertices of a convex polygon (with the number of vertices not exceeding a given one), limiting the initial set of points with known geodetic coordinates. When solving the problem, we developed the following: an algorithm for determining the geodetic coordinates of the polygon vertices; proposals for improving the methodology for constructing the boundaries of the area where points of the aircraft basing areas are located; algorithms for determining the set of points that are the vertices of a convex polygon that limits the initial set of points; an algorithm for reducing the number of vertices of a convex polygon; methods for selecting points by direction and by range; a method for determining the angle at the vertex of a polygon; a method for determining the geodetic coordinates of the vertices of a polygon that do not belong to the original set of points. To effectively solve the problem, we examined several different algorithms, e.g. the Jarvis March algorithm and the Graham scan. The use of the above methods and algorithms makes it possible to determine the geodetic coordinates of the vertices of a convex polygon (with the number of vertices not exceeding a given one), limiting the initial set of points with known geodetic coordinates, and increases the validity and accuracy of determining the geodetic coordinates of the boundary points of the aircraft basing areas.
Technological processes of formation of solid-state wire bonds in the controlled gas environment in the manufacture of porous mesh materials with desired properties: practical application of research results
Authors: Tretyakov A.F.
Published: August 2022

A specific feature of the structure-forming elements used for the manufacture of porous mesh materials is a high specific surface area and a complex configuration of wire meshes, which excludes the possibility of using wire cutting for welding. The research shows that cleaning in Freon-113 is an effective way to remove mineral oils, paraffins, fats and some other contaminants from the mesh surface, since this solvent is stable, non-flammable, non-explosive and does not interact with the workpiece material. In addition, improving the quality of mesh cleaning is achieved by superimposing ultrasonic vibrations in the range of 20...40 kHz. The study introduces flow layouts for the porous materials manufacture by pressure welding of wire meshes from steel 12Kh18N10T and titanium alloy VT2. Findings of the research show that welding envelopes of meshes made of steel I2XI8HI0T by rolling in evacuated makes it possible to obtain porous elements with sufficiently high mechanical and technological properties. It is possible to implement this process on any sheet rolling mill, which is its significant advantage. The paper gives the modes of welding by rolling and diffusion welding of meshes in the manufacture of porous materials. Within the study, we developed a mathematical model that makes it possible to predict the ultimate interlaminar strength for given values of technological parameters of the processes for manufacturing sheet blanks. It is proposed to control the interlayer strength by comparing the calculated data and the results of testing the samples for separation in accordance with the developed methodology. It is advisable to evaluate the control of strength, plasticity in the sheet plane and their anisotropy by comparing the calculated data and the results of testing specimens under conditions of biaxial tension, implemented during hydrostatic buckling through a round matrix.
AN ANALYSIS OF MALAMUD’S PROSE FROM THE PERSPECTIVE OF BUBER’S I-YOU PHILOSOPHY
Authors:   PhD, Foreign Language Center, Academy of Armed Forces, Tirana, Albania, Madani Shpëtim
Published: August 2022

This paper seeks to analyze the prose of Jewish-American writer Bernard Malamud (1914-1986) from a perspective of Martin Buber’s I-You philosophy, which aims toward a transition from I-It to I-You. The I-It connection entails a subject-to-object connection with the world, whereas I-You refers to a subject-to-subject relationship with another human being, including an animal or inanimate object. This sort of relation entails responsibility and is best manifested through love. The study sheds light on the transformation of the Malamudian hero from an egotistical individual who first treats others as merely objects to regarding them as equally important human beings. This moral evolution occurs in the mode of Buberian I-You philosophy. This transition whereby both participating entities are transformed does not occur easily because the protagonist’s past is considerably dark and he is initially distrustful of the world. This way, on his road to redemption the male character is generally encouraged and guided by the female counterpart, serving as an alter ego that reminds him of his responsibility and humanism as a human being. The analysis begins with a short introduction into Buber’s philosophical ideas, which are then illustrated through Malamud’s major works.

Published: August 2022

The aim of this work was to study the cooperage potential of the oak species Quercus pyrenaica, which is widespread throughout the Iberian Peninsula.  A red wine of 2016 vintage was aged in new barrels made from Quercus pyrenaica, Quercus petraea and Quercus alba for 12 months. This process was repeated with a similar red wine from the subsequent vintage using the same barrels in order to compare the performances of the new Q. pyrenaica barrels and Q. pyrenaica barrels that had been used for one year with equivalent Q. petraea and Q. alba barrels. The results indicate that Q. pyrenaica releases levels of β-methyl-γ-octalactone similar to those released by Q. alba and clearly higher than Q. petraea, whereas it releases levels of ellagitannins similar to Q. petraea and clearly higher than Q. alba. These data indicate that Q. pyrenaica is more similar to American oak from an aromatic point of view, since it provides mainly coconut notes, but is more similar to French oak in terms of wine structuration. Moreover, based on the preferences of a trained panel, the wines aged in the Q. pyrenaica barrels were ranked in second position, just behind the wines aged in the Q. petraea barrels and ahead of those aged in the Q. alba barrels. Consequently, Q. pyrenaica seems to have characteristics midway between the two most commonly used oak species for cooperage, confirming its high potential in this regard.

An improved genetic collision avoidance algorithm is proposed in this study to address the problem that Autonomous Surface Vehicles (ASV) need to comply with the collision avoidance rules at sea in congested sea areas. Firstly, a collision risk index model for ASV safe encounters is established taking into account the international rules for collision avoidance. The ASV collision risk index and the distance of safe encounters are taken as boundary values of the correlation membership function of the collision risk index model to calculate the optimal heading of ASV in real-time. Secondly, the genetic coding, fitness function, and basic parameters of the genetic algorithm are designed to construct the collision avoidance decision system. Finally, the simulation of collision avoidance between ASV and several obstacle vessels is performed, including the simulation of three collision avoidance states head-on situation, crossing situation, and overtaking situation. The results show that the proposed intelligent genetic algorithm considering the rules of collision avoidance at sea can effectively avoid multiple other vessels in different situations.
Reaping the Fruits of Informal Urbanism: An Ethnography of Tactical Gardening in Limassol, Cyprus
Authors: Kouros Theodoros
Published: August 2022

Research on informal urbanism has shown that certain informal activities are often discouraged or seen as requiring regulation, while others are endorsed by city authorities. An indicative example is guerrilla gardening, the illicit cultivation of someone else's land, usually positively
perceived as a form of activism. This article illustrates a case from the Global South where guerrilla gardening poses a threat to public spaces, through examining how it is part of an attempt by home and business owners to spill over their legal boundaries and expand into public spaces around
their homes and businesses, most commonly for private gain, sometimes through making those spaces unusable for others. By employing ethnographic research, the article illustrates how plants are being tactically deployed to expand private space into public. It presents results of ethnographic
fieldwork in two parts of Limassol, Cyprus, a relatively poor and neglected neighbourhood and the Limassol Marina, an area that has witnessed a rapid – if not rabid – development in the past few years. It illustrates a unique case where informal tactical gardening interventions

Morphological Characteristics and Fear of Crime: A Case of Public Spaces in the Global North and South
Authors: Iqbal Asifa , Midhat Madiha
Published: August 2022

The morphological characteristics of a city have a direct relationship with the human activities happening in the public spaces. If, however, the public spaces become unsafe, people may avoid them. On the other hand, safe public spaces allow free movement for everyone, which is the
most basic human need and a crucial part of social sustainability. By focusing on the present-day realities that create the link between the implications for ownership and the provision of the public spaces, this research aims to understand the nature of the morphological characteristics of
cities in the Global North and South and its impact on and association with fear of crime. Two case study streets in Stockholm, Sweden, and Karachi, Pakistan, are selected to establish a hypothesis. The study draws upon comprehensive data through a questionnaire survey and morphological analysis.
The results suggest that the selected streets in the Global North and South show a similar morphological structure in terms of street layout, land use, plot patterns, and heights of the buildings but difference in pedestrian flows. In relation to the fear of crime, both streets show parks
as risky places to visit at night. The results also show some differences in terms of people's responses to the fear of crime in relation to the city's morphology. For instance, people avoid vacant plots and petrol pumps in Karachi, while entrances to metro stations and hidden corners of buildings
are considered risky places in Stockholm.
Temporary Urbanism in Times of COVID-19: Creating Refuge in Temporary Urban Spaces of Amman: A Comparative Reflection
Authors: Kamal Ohoud
Published: August 2022

This article is an illustration on how the people of Amman have created temporary urban spaces as a means of coping with COVID-19 restrictions, particularly how they have appropriated spaces in the city normally not used as public spaces to socialize and find refuge outside their homes.
The first section explores the lens of temporary urbanism across the Global North–South as an entry point to explore COVID-19 temporary spaces. The second turns to the context of Amman: first, by relating temporary urbanism to a wider understanding of it as a culturally permanent phenomenon
and then by moving to a more speci fic understanding of the phenomenon. This is followed by three case studies of temporary spaces used during the pandemic in Amman: a parking space; sections of the Bus Rapid Transit (BRT) lane; and a vacant plot of land. The discussion and concluding sections
place the narratives of the temporary spaces of Amman/Global South and Global North in juxtaposition and point to the need to rethink planning practices.
HbA1c and FIB-4 as serologic markers for the risk of progression of stage A heart failure

The use of glycosylated hemoglobin as a diabetic glycemic control and cardiovascular risk marker is well documented. It has also been suggested as a marker for early diastolic hemodynamic changes leading to clinical heart failure, but is less well characterized. This study explored the association between elevated glycosylated hemoglobin and liver Fibrosis-4 values and worsening measures of diastolic cardiac function in order to assess their potential as early serologic markers in cardiovascular disease prevention.A retrospective cohort analysis was conducted in 102 patients presenting to the Parkview Medical Center health system who had received a full resting echo characterized by normal systolic ejection fraction and clinical risk factors associated with stage A heart failure in conjunction with glycosylated hemoglobin and Fibrosis-4 scores within a 3-month time window. Using regression analysis, measures of diastolic cardiac function were assessed in conjunction with rising glycosylated hemoglobin levels characterized as <6.5 and > 6.5 and Fibrosis-4 scores after controlling for the presence of hypertension, coronary artery disease and valvular heart disease. Glycosylated hemoglobin levels > 6.5 were significantly associated with a higher E/e’ ratio and closely associated with an elevated left atrial volume index both indicative of elevated left atrial pressure as a sensitive marker for diastolic cardiac dysfunction. Fibrosis-4 scores did not appear to be clinically associated with progression of diastolic dysfunction.Thus, glycosylated hemoglobin may act as an early marker for identifying patients at increased risk for the progression of stage A heart failure. Fibrosis-4 scores do not appear to be related.
Surgical management of an aneurysmal coronary cameral fistula to the right atrium
Authors: Acker Andrew M , Ibrahim Michael E , Acker Michael A
Published: August 2022

Coronary artery aneurysm and coronary cameral fistula are both often incidentally discovered, and uncommon diagnoses. A coronary artery aneurysm is defined as being 1.5x the size of the adjacent normal coronary artery, while a coronary cameral fistula is a coronary artery that has an abnormal tract directly into a chamber of the heart. In this case report we describe the case of a 72-year-old female who was discovered to have an aneurysmal branch of her right coronary artery fistulized to her right atrium. The fistula had a serpiginous tract and in the midportion of the tract there was a giant aneurysm (3.4 x 3.3 x 3.0 cm) before emptying into the posterior aspect of the right atrium. The aneurysmal aberrant coronary artery was repaired by oversewing the afferent and efferent limbs from the inside. The aneurysm walls were then oversewn. This case demonstrates a unique pathology that was managed with surgical intervention where no standard therapy exists.
Evaluation of a novel rapid genomic test including polygenic risk scores for the diagnosis and management of familial hypercholesterolaemia

Introduction: Familial hypercholesterolaemia (FH) is a common autosomal dominant genetic condition, characterised by elevated LDL cholesterol (LDL-C), leading to premature cardiovascular disease (CVD). Early and accurate diagnosis, with implementation of preventative therapies, has a major impact on reducing premature CVD, morbidity and mortality.Genetic testing is recommended to confirm clinical diagnosis in the proband and enable cascade testing in relatives. There is growing evidence that the risk of CVD conferred by hypercholesterolaemia depends not only on monogenic causes but also on polygenic factors. GENinCode has developed a novel genomic testing system (Lipid inCode®) which we have assessed against an accredited National Health Service (NHS UK) genetic screening service in order to validate its diagnostic and clinical utility.Methods: DNA samples from 40 index cases who had been referred for FH testing in an ISO15189-accredited NHS genetic screening service, were retrospectively tested using the Lipid inCode® assay. The results were compared with those from NHS testing. Results: There was absolute concordance in variant detection between both diagnostic tests for monogenic and polygenic FH, the only difference being in the interpretation and classification of DNA variants based on ACMG guidelines, which did not differ by more than one classification class.  The Lipid inCode® test was equivalent to the NHS test in providing comprehensive genetic analysis that included the assessment of both monogenic (FH) and polygenic determinants of blood cholesterol and including a pharmacogenomic assessment of predisposition to statin-related myopathy.Conclusion: The Lipid inCode® diagnostic test can be undertaken with rapid turnaround and gave the same results as those reported by standard NHS genetic laboratory testing. In addition to assessment of monogenic FH, the Lipid inCode® assay provides additional genetic data, such as polygenic factors contributing to hypercholesterolaemia, a polygenic risk score (PRS) for coronary artery disease (CAD), pharmacogenomic testing for statin myopathy, and genetic predisposition to raised Lp(a).

Statins are now one of the most prescribed drugs in the world and have had a major impact in the prevention and treatment of cardiovascular disease, thereby extending the lives of millions of people across the world. The scientist responsible for the discovery of the first statin, Professor Akira Endo, was recently honoured for ‘exceptional contribution to cardiovascular medicine’ by award of the European Society of Cardiology 2021 Gold Medal (REF).
Study of torque pulsation control of switched reluctance motor by auto-disturbance rejection control
Authors: Yang Yiping , Wu Hongyan , Sun Peng
Published: August 2022

The switched reluctance motor drives the rotor based on the principle of minimum reluctance, which is structurally simpler, but the doubly salient structure of the stator and rotor leads to severe torque pulsation. This paper briefly introduces the switched reluctance motor and the auto-disturbance rejection controller for suppressing the torque pulsation of the switched reluctance motor. Then, the auto-disturbance rejection controller was simulated in the MATLAB software, and it was compared with the direct torque control strategy. The results showed that the switched reluctance motor installed with the self-reluctance controller reached the set rotational speed faster, with a smoother torque change; when the set speed changed abruptly, it was adjusted to the new rotational speed faster, with a smooth and stable torque change; when the load torque changed abruptly, it was adjusted to the new torque smoother and faster, and the adjustment to the rotational speed was also faster.
