We investigate the properties of modulational instability and discrete breathers in the cubic–quintic discrete nonlinear Schr¨odinger equation. We analyze the regions of modulational instabilities of nonlinear plane waves. Using the Page approach [J.B. Page, Phys. Rev. B 41 (1990) 7835], we derive the conditions for the existence and stability f

The introduction of innovative systems like Spatial Planning and Decision Support System (SPDSS) can only be effective and efficient if they are integrated as part of the existing structures and working processes within the organisation. SPDSS is an approach that uses an interactive computer-based system designed to support users like town planners

We present a comparative study on Fourier-based OFDM (FFT-OFDM) and wavelet-based OFDM (DWT-OFDM)in DVB-T system (DWT being the discrete wavelet transform). We found that the DWT-OFDM outperforms FFT-OFDM in AWGN and Rayleigh fading channels. For AWGN channel, the gain in term of energy per bit to noise ratio Eb/No was improved by about 5 dB when t

This research deals with a comparative study of regional architecture between two (2) regions in two (2) countries: Bukit Tinggi, Indonesia, and Negeri Sembilan, Malaysia. Both regions are said to have very similar regional architecture as some of the people of Minangkabau, a tribe in Indonesia, migrated to Malaysia to look for a greener pasture. R

The most common method of obtaining shallow-water bathymetry usually by using single beam echosounder. Recent technology shows that consumer grade drone not only capable to capture aerial images, but also provide DEM of terrain and land area. However, there are less studies and information regarding shallow-water bathymetry derived from consumer gr

The world is facing a Pandemic of unprecedented nature. It is an emergency. This is the Final workshop webinar to culminate the 7 months gestation of surveying, understanding, researching, discussing, and writing since May 2020 to formulate a framework or guidelines for the built environment that addresses the Asian community and locality by ARCASI

This is an outcome of the 3 parts webinar sessions during the Malaysian COVID19 lockdown, depicting CSR Committee's efforts in Pertubuhan Akitek Malaysia (PAM) where, as Co-Chair and the expert member of the team, work behind the scene as from the establishment of the project brief for field hospital to realising linkage with the Ministry of He

Sign language is the priority of communication language between normal and deaf person. Usually normal person tries to communicate with the deaf but due to the absence of knowledge about the sing language making it difficult for them. Before getting a translator, deaf people have to do an appointment with sign language interpreter first. Then, look
