Adaptive evolution is substantially impeded by Hill–Robertson interference in Drosophila [PDF]

open access: yes, 2015
Hill–Robertson interference (HRi) is expected to reduce the efficiency of natural selection when two or more linked selected sites do not segregate freely, but no attempt has been done so far to quantify the overall impact of HRi on the rate of adaptive ...

Rate Adaptation Mechanism with Available Data Rate Trimming and Data Rate Information Provision for V2I Communications [PDF]

open access: yesMobile Information Systems, 2019
We study a rate adaptation mechanism for improving communication performance between a connected vehicle and a roadside unit (RSU) using Wi-Fi during movement in a vehicle-to-infrastructure (V2I) environment. Wi-Fi communication provides various attractive services to connected vehicles during movement.

Data Reduction and Frame Rate Adaptation in WVSN [PDF]

open access: yes2021 17th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2021
Wireless Video Sensor Networks (WVSNs) are becoming one of the most used technologies for surveillance and livestock monitoring. They are composed of small embedded video and camera motes that capture video frames periodically and send them to a specific node called a sink.
