This paper discusses the Software Defined Radio-based Digital Transceiver, focusing on the 256-QAM transceiver used exclusively in 5G. The transceiver discussed here is software-defined, quite unlike that used in 5G.The 5G transceiver switches to the 256-QAM Modulation scheme when the received power is high. This paper uses the SIMULINK model to discuss the 256-QAM Modulation scheme, where the whole transceiver is designed and implemented on an FPGA. The speed and reconfigurability of the FPGAs are the driving forces for such an implementation.

En entreprenant cette recherche sur « le profil des agents de l’Etat affectés dans les services de planification de l’éducation des sous provinces éducationnelles de Kinshasa », nous avons voulu savoir si ces agents exercent vraiment le travail destiné aux planificateurs de l’éducation dans leurs services.

L’intelligence artificielle (IA) est un ensemble de théories et de techniques visant à réaliser des machines capables de simuler l’intelligence humaine. Par extension, dans le langage courant, l’IA inclut les dispositifs imitant ou remplaçant l’homme dans certaines mises en œuvre de ses fonctions cognitives. L’intelligence artificielle est utilisée dans de nombreux domaines. Ses capacités permettent notamment d'automatiser et d'optimiser des tâches complexes et complémentaires, de traiter et d'analyser de vastes quantités de données, et d'améliorer la prise de décision.

The present study of Dicoma tomentosa has been discussed with their habit, habitat, flowering & fruiting, taxonomic enumeration, nativity and physiographic position. The floristic account reveals that occasional threatened distribution of this species found few districts of Uttar Pradesh and dealing as becomes vulnerable species. The specimen deposition of this species which assist its future purpose.

Water is a fundamental carrier of life and energy, and its structural and vibrational properties are increasingly recognized as essential indicators of quality. This study explores water collected from the Ravne Tunnel Complex in Visoko, Bosnia-Herzegovina, a site associated with the Bosnian Pyramid structures. Through a combination of standard laboratory analysis and advanced holistic techniques, we investigate the physical purity, mineral content, and energetic characteristics of this unique subterranean water.

We present a method for the evaluation of the capacitance and charge distribution between the metallic truncated cone of finite length with bottom and the grounded metallic plate. The estimation of capacitance and charge distribution is carried out using the method of moments (MoM) based on pulse function as the basis function and point matching for testing. The matrix elements to be inverted in the solving process are found by dividing the surfaces of the truncated cone and the metallic plate into subsections.

It has frequently been noted that the Cross-Cultural Speech Act Realisation Project (CCSARP) posits a universal categorisation of requests. This serves as a foundation for investigating the request speech act within the Moroccan South-Eastern Amazigh variety (MSEAV) using the CCSARP model. Accordingly, this paper aims to determine whether native speakers of MSEAV employ distinct request strategies that may challenge the universality of conventionally indirect requests. The analysis employs the CCSARP model by Blum-Kulka et al.

Integration of media in teaching and learning is crucial in determining the quality of Christian Religious Education (CRE) curriculum implemented. Despite its importance, stakeholders have raised real concerns about the performance of the subject in secondary schools hence the need to establish stakeholders’ perceptions towards the influence of school based factors on media integration in teaching and learning of CRE in secondary schools in Vihiga County, Kenya.

The increasing sophistication of cheating techniques in academic examinations—such as the use of invisible inks and microprinted notes—presents a challenge to conventional invigilation methods. This paper presents the design and implementation of a handheld, embedded multispectral scanner capable of detecting concealed ink markings in real time. The proposed system employs ultraviolet (UV), infrared (IR), and visible spectrum illumination sources, integrated with a Pi Camera and Raspberry Pi 4 processing unit.

Corporate Governance is a machine of regulations, practices, and tactics that directs and controls a business enterprise, balancing the hobbies of diverse stakeholders like shareholders, control, personnel, and the community. It’s far based on middle concepts of duty, equity, transparency, and duty, ensuring organizations operate ethically, transparently, and in compliance with laws and regulations.
