Highly flexible software network functions (NFs) are crucial components to enable multi-tenancy in the clouds. However, software packet processing on a commodity server has limited capacity and induces high latency. While software NFs could scale out using more servers, doing so adds significant cos...

Performance of in-memory key-value store (KVS) continues to be of great importance as modern KVS goes beyond the traditional object-caching workload and becomes a key infrastructure to support distributed main-memory computation in data centers. Recent years have witnessed a rapid increase of networ...

Limited by the small on-chip memory, hardware-based transport typically implements go-back-N loss recovery mechanism, which costs very few memory but is well-known to perform inferior even under small packet loss ratio. We present MELO, an efficient selective retransmission mechanism for hardware-ba...

Eco-friendly navigation (a.k.a. eco-routing) finds a route from A to B in a road network that minimizes the greenhouse gas (GHG) emission or fuel/energy consumption of the traveling vehicle. As road transport is a major contributor to GHG emissions, eco-routing has received considerable research att...

The Sendai Framework for Disaster Risk Reduction 2015–2030 shifts the focus from managing disasters to reducing risks. Such a shift requires a better understanding of risk in all its dimensions of environment, hazards, exposure, and vulnerability; a disaster risk governance that ensures disaster ris...

In this paper, the downlink file transmission within a finite lifetime is optimized with the assistance of wireless cache nodes. Specifically, the number of requests within the lifetime of one file is modeled as a Poisson point process. The base station multicasts files to downlink users and the sel...

In this paper, the downlink file transmission in one cell with the assistance of cache nodes is studied. Specifically, the base station (BS) reactively delivers files to cache nodes and a requesting user in a multicast manner. Therefore, one file transmission may lead to the cache status update, whi...

A novel polyethyleneimine (PEI)-loaded Fe-doped Cu2(OH)PO4 adsorbent was synthesized via physical impregnation and characterized using XRD, FT-IR, SEM, XPS, and N2 adsorption. Key parameters (Fe doping, PEI loading, temperature, flow rate) affecting CO2 adsorption were optimized using the response s...
