Taha Abdurrahman’ın Fıkhı Ahlaka Dayandırma Çabası: İ’timârî Fıkıhtan İ’timânî Fıkha Geçiş Önerisi
Authors: MAŞALI Münteha
Published: March 2023

Taha Abdurrahman çağdaş meydan okumalara ilişkin incelemelerinde, bu meydan okumalara birinci derecede kaynaklık ettiğini düşündüğü Batılı paradigmayı eleştirmekle kalmamış, yanı sıra İslami telakkinin çağdaş meydan okumaların üstesinden gelmeyi zorlaştıran yönleri üzerine de eleştirel diyebileceğimiz değerlendirmeler serdetmiştir. Anılan meydan okumaların üstesinden ahlak merkezli bakışın hâkim kılınmasıyla gelinebileceğine vurgu yapan Taha Abdurrahman, bir Müslüman için bunun, varoluşunu Allah’ın emaneti bilen bir anlayışa bağlamak anlamına geleceğini belirtmiştir. Fıkhi düşünceyi de bu pradigma ışığında okumaya çalışan Taha Abdurrahman, fıkıh öğretisinin i’timârî fıkıh olarak kavramlaştırdığı emirgören yaklaşımı değil, i’timânî fıkıh olarak kavramlaştırdığı emanetgören yaklaşımı esas almasının gereğine işaret etmiştir. Kendine mal etme, benliği tahkim etme, maddi olanla kayıtlanma ve dini fıkha indirgeme şeklindeki olumsuzlukları bünyesinde barındıran i’timârî fıkıh telakkisinden ve onun beraberinde getirdiği tüm olumsuzluklardan uzak tutacak, buradan hareketle de gerek eşya ile gerekse de Allah’la sağlıklı bir ilişki kurmaya imkân verecek olan şey, fıkhı, manevi-ahlaki bir esasa dayandırmak olacaktır. Taha Abdurrahman’a göre işte bu esas, her şeyi Allah’ın emaneti bilmekle ve fıkhı, ahlaklanmayı sonuç verecek değerlerin tespitini de içine alacak bir genişliğe kavuşturmakla yakalanabilecektir. Böyle bir esas yakalanabildiğinde Allah-insan-âlem arasında i’timârî telakkinin kurmuş olduğu indirgemeci, sahiplenmeci, soyutlayıcı ve maddileştirici ilişki terk edilebilecek ve yerine, sahip olunan her şeyi Allah’ın emaneti gören bir bilinci tahkim edecek ve fıkhın ahlaklanmayı sonuç verecek bir faaliyete dönüşmesini sağlayacak bir yaklaşım geçebilecektir ki Taha Abdurrahman bu yaklaşımı i’timânî/emanetgören fıkıh anlayışı olarak isimlendirmektedir. İşte bu yazıda Taha Abdurrahman’ın önerdiği ahlak merkezli bakışın, fıkhî yaklaşıma sunacağı katkıyı ve çağdaş sorunların üstesinden gelmede fıkhi düşünceye sağlayacağı avantajları özet bir biçimde ele almaya çalışacağız, buradan hareketle de Taha Abdurrahman’ın fikriyatına esas teşkil eden kavramsal çerçeveyi daha yakından tanıma imkânı bulacağız.
Taberî Tefsirinde ‘fî Kelâmi’l-Arab’ Neye Tekabül Eder?
Authors: UZUN Ayşe
Published: March 2023

Taberî, Kur’ân âyetlerini tefsir ederken Arap dilini kaynak olarak kullanmıştır. Bu kaynağa yapılan referansın kavramsallaştırılmış hali, “fî kelâmi’l-Arab” (Arapların dil kullanımı) ifadesidir. Müfessir, tefsirinde 304 defa fî kelâmi’l-Arab ibaresine yer vermiştir. Bu yazının amacı, Câmiu’l-Beyân an Te’vîli Âyi’l-Kur’ân adlı tefsirde Taberî’nin “fî kelâmi’l-Arab” ibaresiyle neyi kastettiğini ortaya koymaktır. Taberî öncesi süreçte “fî kelâmi’l-Arab” kullanımlarını incelediğimizde, bunun sınırlı sayıda olduğu ve söz konusu ibarenin kavramsallaştırmasını yapanın Taberî olduğu ortaya çıkmaktadır. Taberî’nin “fî kelâmi’l-Arab” kalıbını zikrettiği kısımlarda bağlam incelemesi yapıldığında öne çıkan tematik vurgular şöyle sıralanabilir: Salt kelime-lafız tahlili yapmak suretiyle leksikolojik bilgi vermek, kelime tahlilini şiirle desteklemek, muhtelif görüşleri ve rivâyetleri zikrettikten sonra Taberî’nin nezdinde en sahih ve en muteber kabul edilen görüşü değerlendirme pasajı, kıraat meseleleri, Kûfe ve Basra dil okullarıyla alakalı mukayeseler, lehçe bilgisi. Bu tematik vurguların yanı sıra Taberî’nin söz konusu kalıp ifadeyi kullandığı pasajlarda öne çıkan isimler ve üslup da bu çalışmada dikkate alınmıştır. Üslupla kastedilen, söz konusu ibarenin kullanıldığı yerde zikredilen derecelendirme ifadeleridir. Onun “fî kelâmi’l-Arab” ifadesine yer verdiği kısımlarda İbn Abbas, Mücâhid, Katâde ve İbn Zeyd’e yer verdiği görülmektedir. Taberî tefsirinde bir kaynak soruşturması olarak değerlendirilebilecek bu araştırma, müfessirin “fî kelâmi’l-Arab”ı zikrettiği pek çok yerde Arap şiirinden iktibasta bulunduğunu ortaya koymaktadır. Müfessirin “fî kelâmi’l-Arab”ı zikrettiği yerlerin üçte birinde Arap şiirine müracaat ettiği tespit edilmiştir. Bu şiirlerin incelemesi yapıldığında, hicrî ikinci asrı kapsayan döneme ait veriler olduğu görülür. Taberî tefsirinde “fî kelâmi’l-Arab” ile kastedilenin, büyük oranda yazılı literatüre tekabül ettiği söylenebilir. Bu iddiayı desteklemek için tefsirdeki “fî kelâmi’l-Arab” kullanımları incelenmiş ve sayısal değerlendirmeler yapılmıştır. Makale metin incelemesi metoduyla hazırlanmıştır.
MYTHOLOGY IN THE MIRROR: THE NON-FICTIONAL APPROACH IN DEVDUTT PATTANAIK’S MYTHOLOGICAL RETELLINGS
Authors: Pujari Sneha , Jani Tejal
Published: March 2023

Mythology is formed by the set of stories and beliefs, relatively cohesive, to which people have traditionally attributed their origin and the cause of everything that happens around them. Therefore, we can affirm that mythology has the power to influence culture's worldview and belief system. For a better understanding of a region's socio-cultural condition, it becomes crucial to examine popular mythological texts. Among contemporary mythologists, there has been an increase in retelling ancient myths from a new perspective. The paper examines Devdutt Pattanaik's non-fictional attempt to revise classical Indian epics. In process, it reveals to the reader the challenges associated with paradigms that have dominated Indian thought for centuries. Two well-known retellings of Devdutt Pattanaik: Jaya: An Illustrated Retelling of Mahabharata (2010) and Sita: An Illustrated Retelling of Ramayana (2013) have been analyzed to explore the new feminine perspective in mythological retellings of the two great epics of India: TheRamayana and TheMahabharata. It is a qualitative research which follows the exploratory research design. MLA seventh edition style has been used for referencing and citation.

Resumen: El manejo inadecuado de los desechos sólidos domiciliarios determina un gran riesgo para la persona familia y comunidad, Riesgo biológico debido a que la materia orgánica en descomposición; genera una serie de microorganismos, que de hacer contacto ya sea directo por manipulación de la misma o indirecta a través de vectores como las moscas las cucarachas ratas y otros; se produce la contaminación de los alimentos, el agua y por ende la aparición de enfermedades principalmente gastrointestinales. Existe riesgo físico y químico porque en los hogares se genera residuos peligrosos a consecuencia de las actividades domésticas. De ahí que surge la necesidad de realizar un estudio que permita determinar en una primera fase; “las practicas que los pobladores de Cobija tienen en el manejo de basura domiciliaria”. El estudio realizado por 90 estudiantes de la Carrera de Enfermería de la Universidad Amazónica de Pando-Bolivia; ha tenido un enfoque cualitativo y cuantitativo de carácter descriptivo y de corte transversal. Habiéndose tomado una muestra de 950 familias de 12 barrios de Cobija de una población de 15.000 habitantes, aplicándose para la recolección de datos; la encuesta y la observación. Los resultados muestran que el 73% de la población no separa residuos, acopia juntos los peligrosos y no, peligrosos degradables y no degradables y como eliminación inicial lo dejan afuera de los domicilios formando en algunos sitios micro basurales. El 9% elimina la basura en terrenos baldíos y en medio de la maleza, apenas el 2% separa latas de aluminio que son vendidos a personas que acopian para llevar al Brasil. En la fase dos, se realiza un análisis crítico y reflexivo de los resultados y se decide realizar una orientación a las familias mediante visitas domiciliarias con el objeto de prevenir riesgos a la salud debido al manejo inadecuado de los residuos sólidos, el programa fue ejecutado por estudiantes quienes elaboran sus medios educativos, y practican las técnicas educativas e informativas para prevenir enfermedades y daños al medio ambiente.
O USO DE MAPAS CONCEITUAIS COMO UMA PROPOSTA DE APRENDIZAGEM NO ENSINO DE CIÊNCIAS
Authors: Lopes Daniella da Silva , Paula Sara Correia de
Published: March 2023

O contexto educacional atual provoca o professor para repensar sobre suas práticas pedagógicas, pois o cenário que estamos inseridos modifica-se rapidamente e a escola precisa atualizar-se e acompanhar as inovações. O que se observa é uma tendência na qual o professor é visto como o mediador do conhecimento e o estudante como um ser ativo, protagonista de sua aprendizagem, dotado de conhecimentos prévios e em busca de satisfazer suas curiosidade e anseios. Outro aspecto a ser considerado é que o próprio ensino de Ciências sofreu mudanças significativas quanto às concepções de como se constrói o conhecimento científico, bem como sua utilização no cotidiano. Mapas conceituais podem ser considerados como esquemas para estruturar conceitos estudados de maneira sintetizada e organizada. Esses esquemas estão fortemente relacionados com a teoria da aprendizagem significativa, a qual acredita que as pessoas organizam seus conhecimentos por meio de uma hierarquização dos conceitos, ao estabelecerem uma rede de proposições. A utilização dos mapas constituiu um recurso metodológico relevante por se alinhar a uma formação teórica adequada às necessárias intervenções na realidade estudada e por facilitar a apropriação de conceitos científicos pelos alunos. O presente trabalho tem como principal objetivo, mostrar a importância da utilização dessa ferramenta didática para uma aprendizagem significativa de conceitos científicos no Ensino de Ciências pensando numa proposta prática e dinâmica de aprendizagem.

A sociedade atual carece de profissionais que apresentem habilidades e saberes perti- nentes aos novos paradigmas vigentes. Desta forma, torna-se imprescindível repensar as atitudes relativas à formação de profissionais e que atingem diretamente as estruturas da identidade profissio- nal de cada indivíduo. As ciências físicas têm apresentado enorme avanço e as conquistas de tais ciências fomentam a tecnologia e a engenharia que produzem diversos aparatos tecnológicos para a sociedade. Dessarte, o desconhecimento de vínculos entre ciência, tecnologia e sociedade afasta o profissional do ensino muitas vezes de usar tais tecnologias para aproximar a vivência de seu aluno em uma sociedade tecnologicamente evoluída com a teoria científica básica. O presente trabalho emergiu do questionamento se a robótica educacional abordada, seguindo os pressupostos constru- cionistas, pode vir a modificar as atitudes de licenciandos e posteriormente influenciar as práticas docentes com vista à construção da identidade profissional. Assim, o objetivo central desta tese é avaliar a contribuição da robótica educacional, por meio do uso da plataforma Sbotics e amparada metodologicamente pelo construcionismo, na modificação da ação docente de licenciandos do curso de Física bem como sua identidade profissional.

Effect of Graded Mesh Number on the Solution of Convection-Diffusion Flow Problem with Quadratic Source
Authors: Aslam Abdullah
Published: March 2023

Convection-diffusion phenomena are fundamentally modelled in a variety of engineering fields and physical sciences. A suitable meshing strategy is needed in computational fluid dynamics to solve model problems numerically. Unintentional implementation of the approach could lead to subpar solutions such as erroneous oscillations, over- or under-predictions, and excessive computing time. This paper highlights the significance of the influence of mesh structure on the solution of convection-diffusion flow problem with quadratic source for flow parameters of interest. Particularly, it presents the accuracy of the solution of the flow problem at low Peclet number with respect to graded mesh number, where the expansion factor used is based on an established linear logarithmic model involving Peclet number derived in previous works. The problem is solved by assigning several mesh intervals to graded mesh against each Peclet number of interest. Based on the values of the interval and Peclet number, 16 test cases are considered. Quantitative results lead to orders of accuracy of the solution of the flow problem. The effect of graded mesh number on the accuracy thus serves as a reference for a more structured decision-making and improves the heuristic process in choosing the computational domain mesh with expected order of accuracy for the numerical solution of the problem particularly in the calculation of scalar concentration. The orders of accuracy confirm the profiles of concentration.
CFD Simulation of Laminar Rotating Flow Inside a Membrane Filter Vessel

Published: March 2023

In this study, computational fluid dynamics (CFD) was used to simulate a steady-state rotating flow inside a filtration system. The shape of a 3-D vessel was designed and then meshed using ANSYS design modular (DM) and workbench mesh. The laminar viscous regime was employed; it was identified using the Reynolds number formula. As a boundary layer, the zero inlet velocity and atmospheric pressure were imposed on the inlet boundary. The obtained results showed that for a rotating velocity of 50 rpm, the shear stress distribution on the membrane surface is extremely low, except for four narrow regions situated between the extremities of the impeller and the vessel wall. The pressure variation versus z axes, below the impeller, was almost constant, and it was unevenly distributed on the membrane surface, with two areas of negative pressure. The velocity values below the impeller were higher than those above. This study provides good insights that suggest designing the impeller shape under the most extreme conditions (rotating velocity, flow regime, and pressure inlet) of the membrane. The filtration process will be performed in a future study.
An Improvement in Boundary Treatment of Solid Boundary Using ISPH Approach
Authors: Nur’Ain Idris  , Mitsuteru Asai  , Hamidun Mohd Noh
Published: March 2023

Incompressible Smoothed Particle Hydrodynamic (ISPH), one of the particle methods, is frequently employed to address a variety of challenging physical issues, such as those involving free surface flow. For measuring the precise and reliable pressure close to the boundary, the study of boundary treatment has lately been an active research field in the mesh-free or particle approach. If the solid barrier's appropriate pressure boundary condition is not met, fluid particles may penetrate it. This study proposes a straightforward boundary treatment that can satisfy the non-homogenous Neumann boundary condition on the solid boundary and the Dirichlet condition on the water surface. The main idea behind our suggested approach is that by solving a modified pressure Poisson equation, these boundary conditions are automatically satisfied. This technique can be improved such that it can be applied to any shape having a concave-convex boundary in addition to basic solid boundaries. The suggested method was tested using the hydrostatic case, followed by a numerical analysis validated using a 3D dam break flow with an opening gate and a Stanford rabbit demonstration. The outcome of the numerical modelling simulation was then contrasted with the findings of the theoretical and experimental studies. The obtained findings support the suggested technique by providing a good tendency and similarity output that enhances the boundary treatment on solid boundaries.

In the current study, cross-temperature and concentration gradients are used to model the in a binary fluid contained in an angled square cavity. Using a method, the , , and conservation equations were numerically solved. The inclined cavity under equal solutal buoyancy and thermal forces was the subject of the study . Since the horizontal components of the thermal and singular volume forces were equal but opposed to one another, an equilibrium solution for this situation that corresponds to the rest state of the immobile fluid is feasible. However, this equilibrium solution becomes unstable above a specific critical value of the , leading to vertical density stratification inside the enclosure. The results are shown using the and as well as the and for the flow intensity.

Öğretmen adayları plan hazırlarken karşılaştıkları zorlukların üstesinden iş birliği yaparak geldiklerini ifade etmişlerdir. Süreçte karşılaştıkları zorluklar öğretmen adaylarının BTÖ’ye yönelik daha çok pratiğe ihtiyaç duyduklarını göstermektedir. BTÖ lisans döneminde tanıtılmalı ve öğretmen adaylarına deneyim kazanabileceği işbirlikli ortamlar sunulmalıdır.
New Observational H(z) Data from Full-spectrum Fitting of Cosmic Chronometers in the LEGA-C Survey
Authors: Jiao Kang , Borghi Nicola , Moresco Michele , Zhang Tong-Jie
Published: March 2023

In this work, we perform a full-spectrum fitting of 350 massive and passive galaxies selected as cosmic chronometers from the LEGA-C ESO public survey to derive their stellar ages, metallicities, and star formation histories. We extensively test our results by assessing their dependence on the possible contribution of dust, calibration of noise and signal, and use of photometric data in addition to spectral information; we also identify indicators of the correct convergence of the results, including the shape of the posterior distributions, the analysis of specific spectral features, and the correct reproduction of the observed spectrum. We derive a clear age–redshift trend compatible with the aging in a standard cosmological model showing a clear downsizing pattern, with more massive galaxies being formed at higher redshift (z

f
∼ 2.5) with respect to less massive ones (z

f
∼ 2). From these data, we measure the differential aging of this population of cosmic chronometers to derive a new measurement of the Hubble parameter, obtaining

This analysis allows us to compare for the first time the differential ages of cosmic chronometers measured on the same sample with two completely different methods, the full-spectrum fit (this work) and the analysis of Lick indices, known to correlate with the age and metallicity of the stellar populations. Albeit an understood offset in the absolute ages, the differential ages have proven to be extremely compatible between the two methods, despite the very different data, assumptions, and models considered, demonstrating the robustness of the method.

We report the discovery of a super-Jovian 2:1 mean-motion resonance (MMR) pair around the G-type star TIC 279401253, whose dynamical architecture is a prospective benchmark for planet formation and orbital evolution analysis. The system was discovered thanks to a single-transit event recorded by the Transiting Exoplanet Survey Satellite mission, which pointed to a Jupiter-sized companion with poorly constrained orbital parameters. We began ground-based precise radial velocity (RV) monitoring with HARPS and FEROS within the Warm gIaNts with tEss survey to constrain the transiting body’s period, mass, and eccentricity. The RV measurements revealed not one but two massive planets with periods of

Asymétries sociétales de l’imaginaire symbolique
Authors: Accati Luisa
Published: March 2023

Devenu religion de l’Empire romain, le christianisme se trouve confronté à une culture de domination. L’autorité religieuse est tenue de pardonner les tueries des conquêtes impériales. Cependant, tandis que le pardon garantit l’impunité, les images sacrées montrent l’impossibilité d’être délivré de la culpabilité. Le crucifix, qui représente le Christ tué et non ressuscité, s’affirme comme le symbole dominant. Les mots pardonnent, les images accusent. Exposé au regard des fidèles, le corps non enterré de la victime dénonce un contentieux ouvert avec Dieu. La violence devient l’un des fondements de la société.

« En même temps »
Authors: Colin Robert C.
Published: March 2023

« L’accueil de l’ infans dans l’adulte », notion plus ferenczienne que freudienne, ne fait pas l’unanimité chez les psychanalystes. Plutôt que d’entrer dans un débat intellectuel qui chercherait à affirmer de quel côté politique il est souhaitable de se trouver – Freud ou Ferenczi ? – j’ai choisi de me former ma propre opinion à travers quelques courtes séquences cliniques de psychanalyse d’adultes glanées pour l’occasion. Cette étude m’amène à mesurer l’importance du modèle du « en même temps ».
Troie en Ukraine

En partant du mot « génocide », l’auteur constate qu’avec les guerres, les mots risquent de perdre tout ou partie de leur polysémie. De même, une pluralité de perspectives est nécessaire pour appréhender la réalité de celles-ci. Il ouvre la perspective arendtienne de la « guerre d’anéantissement » pour mieux comprendre la guerre en Ukraine.
L’assistance médicale à la procréation avec tiers donneur à la suite de la loi du 2 août 2021
Authors: Mesnil Marie
Published: March 2023

La loi du 2 août 2021 relative à la bioéthique a fait évoluer le droit de l’assistance médicale à la procréation avec tiers donneur de manière assez significative, sans pour autant rompre avec les principes éthiques fondateurs : les couples de femmes et les femmes seules non mariées peuvent bénéficier d’un don de spermatozoïdes, l’autoconservation de gamètes sans motif médical est autorisée et un accès à l’identité et aux données non identifiantes du donneur a été aménagé pour les personnes conçues à partir d’un don de gamètes. Ces évolutions importantes ne doivent toutefois pas masquer les nombreuses incertitudes qui demeurent quant à l’usage des gamètes au sein du couple – lorsque celui-ci est constitué de deux femmes ou d’une personne trans – ou encore quant à l’accès plus général à l’ amp pour les personnes qui ont changé de mention de sexe à l’état civil.
Le budget participatif clermontois, exemple d’un dispositif participatif qui devient le catalyseur des enjeux environnementaux
Authors: Éric Agbessi , Nicolas Duracka
Published: March 2023

Le Budget Participatif de la Ville de Clermont-Ferrand est une politique publique qui répond à une triple situation de crise démocratique (de l’autorité politique et scientifique, de la participation démocratique et de la délibération publique). Sur les 32 projets votés par les citoyens, un quart ont une teneur écologique. Ainsi, les micros espaces publics délibératifs ouverts par l’initiative ont été marqués par une fragmentation. Premièrement, une tendance à produire des échanges régulés par une vision « instituée » du développement durable remettant très peu en cause notre modèle de développement citadin. Deuxièmement, l’émergence d’une forte incommunication et la marginalisation des porteurs de projets porteurs de visions transformatrices (décroissantes ou résilientes).
Accès à l’information : un enjeu de la participation citoyenne au Québec face aux projets miniers en région éloignée
Authors: Germain Sara
Published: March 2023

Dans le contexte québécois, bien que le Bureau d’audiences publiques en environnement (Bape) jouisse d’une bonne crédibilité en tant qu’institution de participation citoyenne (Gauthier & Simard, 2011), son efficacité fait curieusement défaut dans le cas de l’industrie minière où, malgré certains cas de forte opposition citoyenne, aucun projet d’exploitation n’a été refusé par le gouvernement (Deneault & Sacher, 2012). Cet article pose un regard critique sur les conditions de la participation citoyenne en regard de l’examen de projets miniers au Québec, particulièrement en région éloignée en analysant la mobilisation citoyenne découlant de l’annonce en 2017 du projet Authier Lithium de la minière Sayona Québec Inc. (SQI) en Abitibi.
Associations Between Older Adults' Loneliness and Acceptance of Socially Assistive Robots: A Cross-Sectional Study
Authors: Huppertz Christian , Forbrig Theresa A. , Lengert-Brzozowski Sandra , Gräske Johannes
Published: March 2023

The use of socially assistive robots (SARs) to enable older adults (aged ≥65 years) to live independently for as long as possible has been researched for several years. Of particular interest is the way SARs can combat loneliness. A quantitative cross-sectional study was conducted with 61 older adults in living facilities in Berlin, Germany. Paper-based questionnaires were used to elicit experiences of loneliness and determine the level of acceptance of SARs. Mean score (39.3) of the loneliness scale was in the average range for this population. Mean score (56.1) of acceptance of SARs was on a moderate level. Regression analyses showed that loneliness did not influence the acceptance of SARs by older adults in the sample, which was contrary to findings in the literature. Further studies might generate more accurate data and accelerate the development of robots to make them more attractive for social purposes. [

Human motion recognition based on Nano-CMOS Image sensor
Authors: Li Shangbin , Liu Yu
Published: March 2023

Human motion recognition is of great value in the fields of intelligent monitoring systems, driver assistance system, advanced human-computer interaction, human motion analysis, image and video processing. However, the current human motion recognition methods have the problem of poor recognition effect. Therefore, we propose a human motion recognition method based on Nano complementary metal oxide semiconductor (CMOS) image sensor. First, using the Nano-CMOS image sensor to transform and process the human motion image, and combines the background mixed model of pixels in the human motion image to extract the human motion features, and feature selection is conducted. Second, according to the three-dimensional scanning features of Nano-CMOS image sensor, the human joint coordinate information data is collected, the state variables of human motion are sensed by the sensor, and the human motion model is constructed according to the measurement matrix of human motions. Finally, the foreground features of human motion images are obtained by calculating the feature parameters of each motion gesture. According to the posterior conditional probability of human motion images, the recognition objective function of human motion is obtained to realize human motion recognition. The results show that the human motion recognition effect of the proposed method is good, the extraction accuracy is high, the average human motion recognition rate is 92%, the classification accuracy is high, and the recognition speed is up to 186 frames/s.
