Feasibility of using Nanofiltration membranes to delay Reverse Osmosis membrane fouling and to reduce energy consumption (BWC desalination plant) [PDF]
Journal of Water and Environmental Nanotechnology, 2023 The Beni Saf Water Company (BWC) desalination plant in Ain Témouchent (Algeria) uses reverse osmosis technique. This process, which is based on dense membranes operating at high pressure, produces a permeate with characteristics that exceeds the ...

Synoptic conditions and atmospheric moisture pathways associated with virga and precipitation over coastal Adélie Land in Antarctica [PDF]
The Cryosphere, 2020 Precipitation falling over the coastal regions of Antarctica often experiences low-level sublimation within the dry katabatic layer. The amount of water that reaches the ground surface is thereby considerably reduced. This paper investigates the synoptic

Microphysics and dynamics of snowfall associated with a warm conveyor belt over Korea [PDF]
Atmospheric Chemistry and Physics, 2020 On 28 February 2018, 57 mm of precipitation associated with a warm conveyor belt (WCB) fell within 21 h over South Korea. To investigate how the large-scale circulation influenced the microphysics of this intense precipitation event, we ...

Formal verification of LTE-UMTS and LTE–LTE handover procedures [PDF]
Computer Standards & Interfaces, 2017 Long Term Evolution (LTE) is the most recent standard in mobile communications, introduced by 3rd Generation Partnership Project (3GPP). Most of the works in literature about LTE security analyze authentication procedures, while handover procedures are far less considered.

MIMO Detector for LTE/LTE-A Uplink Receiver [PDF]
Journal of Signal Processing Systems, 2018 We propose a carefully selected receiver structure, detector and detector implementation architecture for multiple-input multiple-output (MIMO) uplink base station receiver for fourth generation (4G) wireless cellular systems. First, we compare different receiver algorithms and structures for single-carrier frequency-division multiple access (SC-FDMA ...
