Quantifying performance of sheltered link-way facility in Singapore using human-centric indicators
Pedestrian link-ways are important street facility for first-/last-mile mobility. This study compared pedestrians’ walking experiences on sheltered/unsheltered link-ways by collecting their perceived walking time/distance.

A Scheme for Long-distance High-resolution Detection of Fiber Link
Aiming at the problem of low spatial resolution of Optical Time Domain Reflectometer (OTDR) in long distance optical fiber link detection, this paper proposes a new scheme of Linear Frequency Modulation (LFM) -Golay OTDR.

In this paper, we characterize all links in the 3-sphere with bridge number at least three that have a bridge sphere of distance two. We show that a link L has a bridge sphere of distance at most two then it falls into at least one of three categories: (1) The exterior of L contains an essential meridional sphere.

Oracles for Distances Avoiding a Failed Node or Link [PDF]
We consider the problem of preprocessing an edge-weighted directed graph $G$ to answer queries that ask for the length and first hop of a shortest path from any given vertex $x$ to any given vertex $y$ avoiding any given vertex or edge. As a natural application, this problem models routing in networks subject to node or link failures.

A study of coastal and harbor channel effects on Underwater Wireless Optical Communication systems with BCH and LDPC error correction codes [PDF]
Owing to the benefits that they offer over traditional acoustic and RF communication, including higher data rates, reduced latency, and enhanced safety, underwater wireless optical communication (UWOC) systems have gained a solid focus.
