A REVIEW OF THE DESIGN AND DEVELOPMENT OF MICROSTRIP MULTIBAND BANDPASS FILTER FOR 5G SYSTEMS

Anitha George — 2024-05-05

Microstrip bandpass filters have been the subject of research for a very long period to suit the needs of contemporary multiservice wireless communication systems. Multiband bandpass filters, or BPFs, are necessary for the receiver front end to work as a single unit that can serve many bands simultaneously. Particularly promising are the compact design, low integration cost, and simplicity of manufacture using printed circuit technology of planar bandpass filters. The design and implementation of filters for fifth-generation (5G) mobile communication systems is complicated due to the necessity for high integration, low cost, and high-speed data transfer. This paper offers and discusses a comprehensive assessment of existing research on microstrip single multiband bandpass filter designs for fifth-generation applications, with an emphasis on the most recent advances.

Transformative Pedagogy: Harnessing AI tools for Enhanced Powerpoint Creation in Educational Settings

C R Balakrishnan — 2024-06-21

"Transformative pedagogy" refers to an approach to teaching and learning that goes beyond the transmission of information to encourage critical thinking, reflection, and the development of students as independent learners and responsible citizens. It aims to transform not only what students know but also how they think, interact with information, and engage with the world around them. integrating Artificial Intelligence (AI) into transformative pedagogy can amplify its impact by leveraging advanced technologies to enhance learning experiences. Artificial Intelligence (AI) in education refers to the application of advanced technologies, particularly machine learning, natural language processing, and data analytics, to enhance and transform various aspects of the educational process. The integration of AI in education holds the potential to revolutionize traditional teaching and learning methods, offering innovative solutions to address challenges and improve overall educational outcomes.

A survey on the need to incorporate rainwater harvesting systems as an alternative domestic water source in Ghana

Duke Mensah Bonsu ANTWI — 2024-07-19

This research survey seeks to gather responses in rainwater gathering and storage using harvesting systems as a key alternative. About 502 responses were gathered. Averaging 8 persons per household and 6 rooms per household. 73.1 % of males and 26.9 females. The main source of water includes GWCL (37.8 %), Borehole/groundwater (59.6 %), both GWCL & Borehole (1 %), Both Rainwater & GWCL (1 %), other unspecified sources (0.6 %). 58.2 % responded ‘Yes’ to the collection of rainwater to 41.8 ‘No’ responses. Methods for collecting rainwater includes roof gutter & drain spouts (37.8 %), open containers (40.8 %), other unspecified means (14.7 %). 56.8 % said ‘YES’, with about 2 % saying ‘IF THE NEED BE’ and 41.2 % responding ‘NO’ to the need to collect rainwater for future use. Roofs age also contribute to water quality, 45.2 % were above 10 years, 30.7 % between 7-10 years, 14.3 % between 4-6 years and 9.8 % between 1-3 years. Furthermore, 65.3 % respondents had heard of rainwater harvester systems. About 75.7 % responded to ‘NO’ for not having rainwater systems installed. About 83.3 % responded ‘NO’ to treating the collected water before use. About 64.1% are willing to treat the harvested rainwater. About 61.4 % respondents indicated the reduction in their water bill. The t-statistic and P-value results suggested collecting rainwater does not appear to be associated with a difference in the number of rooms in a household. The Chi-square statistic of 14.394 and a P-value of 0.000148 establishes a strong association between collecting rainwater at the household during the rainy seasons and seeing a reduction in water bills during the rainy season compared to reliance on traditional water supplies alone. Households that collect rainwater are significantly more likely to see a reduction in their water bills. There is a growing interest in the gathering, harvesting and the purification of rainwater for domestic use as a great alternative.
