In this paper, an Ultra-wideband Balance Antipodal Vivaldi Antenna in planar and h-plane array configuration is presented. The comparison of four elements of BAVA array in both planes has been observed. Each element of an antenna printed on the glass-reinforced epoxy laminate material (FR4) with a thickness of 1.5mm and relative permittivity of 4.3

This paper present a detection technique of metal placed inside and between two walls. A unique scheme of recognition of metallic objects through Ultra Wide Band (UWB) Modified Antipodal Vivaldi Antenna (MAVA) frequency range of (3.1GHz to 10.6 GHz) is presented in this paper. The working mechanism of detection system based on Time Domain Reflectro

Quality assurance in higher education is a hot topic with the increased number of students graduating from postgraduate programs offered by the higher education institutions. This qualitative study aimed to look at the history and the current status of the quality assurance mechanisms in the Maldives; identify its strengths and weaknesses; and make

In this paper, A Novel 1 to 4 modified Wilkinson power divider operating over the frequency range of (3 GHz to 8 GHz) is proposed. The design perception of the proposed divider based on two different stages and printed on FR4 (Epoxy laminate material) with the thickness of 1.57mm and ϵr =4.3 respectively. The modified design of this power divider

H-plane array configuration of different elements of balance antipodal Vivaldi antenna is presented in this paper. The configuration of an antenna is based on the improvement in radiation characteristics of BAVA. The use of two and four elements placed in h-plane configuration is considered. Each single element antenna is printed on FR4 substrate o

This paper aims to identify the determinants that influence the credit risk of global Islamic banks. The paper employs the static panel models in the investigation process and uses the multiple variables - focus variable, bank-specific variable and macroeconomic variables which are collected from the database of banks’ annual reports, DataStream

In this paper, climate change and global warming are the biggest current issues in the industrial sectors. The green supply chain managements (GSCM) is one of the crucial input to these issues. Effective GSCM can potentially secure the organization's competitive advantage and improve the environmental performance of the network activities. In t

Beberapa hari yang lalu, negara kita dikejutkan sekali lagi dengan berita perkahwinan yang melibatkan seorang kanak-kanak perempuan. Namun apa yang lebih membimbangkan, kanak-kanak itu baru berusia 11 tahun dan merupakan antara pengantin perempuan termuda yang pernah dilaporkan di Malaysia. Berikutan dari itu, pelbagai spekulasi didengari berkenaan

Previously, there were many extraction methods that had been done on extracting the oil such as centrifugation, chilling and thawing, hot and cold extraction, on seeds, waste products and plants. Based on those oil extraction methods (OEM), further study is needed to develop more effective processes as most of the methods were having many disadvant

Thyroid is the biggest gland in the body and in case of thyroid cancer, the biological characteristics and prognosis are completely different for different types of thyroid cancer. There are four types of thyroid cancer; papillary, follicular, medullary and anaplastic thyroid cancers. Among these type, anaplastic carcinoma is the rarest and deadlie
