On the Outage Capacity of Transdermal Optical Wireless Links with Stochastic Spatial Jitter and Skin-Induced Attenuation

Photonics, 2021
The tremendous development of both optical wireless communications (OWC) and implantable medical devices (IMDs) has recently enabled the establishment of transdermal optical wireless (TOW) links that utilize light waves to transfer information inside the

Ergodic capacity analysis of downlink distributed antenna systems using stochastic geometry [PDF]

2013 IEEE International Conference on Communications (ICC), 2013
This paper studies the ergodic capacity of a multicell distributed antenna system (DAS), where remote antenna ports are spread within each cell to cooperatively transmit to user terminals. Unlike most prior studies which assume the antenna ports to be deployed at fixed locations, this paper assumes the antenna ports to be distributed as a spatial ...

Sensitivity analysis for stochastic user equilibrium traffic assignment with constraints

Advances in Mechanical Engineering, 2017
A mathematical programming method for sensitivity analysis of the link-capacitated stochastic user equilibrium model is presented in this article. By the sensitivity matrices, the changes in the network flows can be easily obtained, while some links ...

Understanding the Capacity Utilization Rate and Overcapacity of China’s Coal Industry and Interprovincial Heterogeneity

IEEE Access, 2019
The overcapacity of China's coal industry is mainly caused by the inefficiency of the production processes and the imbalance between market supply and demand (effective supply shortage).

Identification of Choquet capacity in multicriteria sorting problems through stochastic inverse analysis

CoRR, 2020
In multicriteria decision aiding (MCDA), the Choquet integral has been used as an aggregation operator to deal with the case of interacting decision criteria. While the application of the Choquet integral for ranking problems have been receiving most of the attention, this paper rather focuses on multicriteria sorting problems (MCSP).

Reverse Poisson Counting Process with Random Observations

Mathematics
This paper introduces the Reverse Poisson Counting Process (RPCP), a stochastic model derived from the Poisson counting process with limited and random capacity, characterized by counting backward from a defined maximum level.

A Modified Network-Wide Road Capacity Reliability Analysis Model for Improving Transportation Sustainability

Algorithms, 2020
Reserve capacity is the core of reliability analysis based on road network capacity. This article optimizes its bi-level programming model: the upper-level model has added service level coefficient and travel time limit, which realizes the unification of

A Study of Mixed Non-Motorized Traffic Flow Characteristics and Capacity Based on Multi-Source Video Data

Sensors
Mixed non-motorized traffic is largely unaffected by motor vehicle congestion, offering high accessibility and convenience, and thus serving as a primary mode of “last-mile” transportation in urban areas. To advance stochastic capacity estimation methods
