Cem Gursoy, Cemil (author), Kraak, D.H.P. (author), Ahmed, Foisal (author), Taouil, M. (author), Jenihhin, Maksim (author), Hamdioui, S. (author)Memory designs require timing margins to compensate for aging and fabrication process variations. With technology downscaling, aging mechanisms became more apparent, and larger margins are considered necessary. This, in return, means a larger area requirement and lower performance for the memory. Bias Temperature Instability (BTI) is one of the...conference paper 2022

(author), Kim, Youngsok (author), Lee, Jinho (author)Sequence alignment forms an important backbone in many sequencing applications. A commonly used strategy for sequence alignment is an approximate string matching with a two-dimensional dynamic programming approach. Although some prior work has been conducted on GPU acceleration of a sequence alignment, we identify several shortcomings that limit...conference paper 2022

Mohamed, Ahmed (author), Ahmed, Ezzat (author), Alshehri, Fahad (author), Abdelrady, Ahmed (author)The Nubian Sandstone Aquifer System (NSAS) is made up of three major sub-basins: Kufra, Dakhla, and the N. Sudan Platform. It is one of the world’s largest groundwater systems. The aquifer’s hydrologic setting, connectivity of its sub-basins, and groundwater flow across these sub-basins are currently unclear. To address these issues, we used...journal article 2022

Hamida, M.B. (author), Ahmed, Wahhaj (author), Asif, Muhammad (author), Almaziad, Faris Abdullah (author)The buildings and construction sector accounts for the majority of the energy consumption in the Kingdom of Saudi Arabia (KSA). For a sustainable future, energy consumption in the sector should be reduced and existing buildings need to be energy retrofitted. A number of studies present energy retrofitting of residential buildings in KSA;...journal article 2021

Aboudi, Kaoutar (author), Ahmed, Banafsha (author), Tyagi, Vinay Kumar (author), van Lier, J.B. (author)Aromatic compounds such as aromatic amines (AAs) or lignocellulose biomass derivatives are often recalcitrant to biological processes (i.e., anaerobic digestion). The level of recalcitrance is usually explained by the biochemical structure of the compounds, which determines their removal. AAs are present in dye wastewaters mainly originated...book chapter 2021

Ahmed, M.B.M. (author)Climate change (CC), as predicted by several global climate models, is very likely to have severe impacts in the future, on top of all other global changes. These impacts may have significant influence on natural resources especially surface and groundwater. This influence is particularly problematic for the Mediterranean coastal areas, and...doctoral thesis 2020

Naus, Floris Loys (author), Schot, Paul (author), van Breukelen, B.M. (author), Ahmed, Kazi Matin (author), Griffioen, Jasper (author)In southwestern Bangladesh, clean drinking water is scarce, since rainwater is only available during the monsoon, pond water is often bacteriologically polluted, and groundwater may exhibit high salinity and arsenic levels. Managed aquifer recharge (MAR) might potentially provide safe drinking water by storing abundant freshwater from the wet...journal article 2020

Ahmed, N. (author), Qiu, T.D. (author), Bertels, K.L.M. (author), Al-Ars, Z. (author)BACKGROUND: In Overlap-Layout-Consensus (OLC) based de novo assembly, all reads must be compared with every other read to find overlaps. This makes the process rather slow and limits the practicality of using de novo assembly methods at a large scale in the field. Darwin is a fast and accurate read overlapper that can be used for de novo...journal article 2020
