Stabilising Routines in Complex Emergencies: How Basic Service Continuity Shapes Perceived Security

Public Administration and Development, EarlyView.
ABSTRACT This study examines how locally embedded actors describe the relationship between basic service continuity and perceived security in complex emergencies, with particular attention to the stabilisation of everyday routines. Using Proximity‐Predictability‐Attributability (PPA) as an analytic lens, we trace how interviewees relate access to water,

Elevator dynamic monitoring and early warning system based on machine learning algorithm

IET Networks, EarlyView., 2022
In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

Technopolitical Energy Governance as Administrative Closure: Digitalisation and the Depoliticisation of Energy Politics in Iran and Saudi Arabia

Public Administration and Development, EarlyView.
ABSTRACT Digitalisation is widely framed as a route to more efficient and participatory public administration. In authoritarian settings, however, digital governance often works less as administrative improvement than as a technopolitical instrument for managing dissent and insulating policy from contestation.

Performance analysis of physical layer security based on channel correlation

Tongxin xuebao, 2021
In view of the correlation of the main and eavesdropper’s channels in physical layer security, the impact of channel correlation on the secrecy performance was studied, the exact form ulations of ergodic secrecy capacity and secrecy outage probability ...

ADAPT: An Autonomous Forklift for Construction Site Operation

Journal of Field Robotics, EarlyView.
ABSTRACT Efficient material logistics are critical in controlling costs and schedules in the construction industry. However, manual material handling remains prone to inefficiencies, delays, and safety risks. Autonomous forklifts offer a solution to streamline on‐site logistics, reducing reliance on human operators and mitigating labor shortages.

On the Outage Performance of Selection Amplify-and-Forward Relaying Scheme

IEEE Communications Letters, 2014
In this letter, we propose a selection amplify-and-forward (AF) relaying scheme which has the lower outage probability than that of a conventional AF relaying scheme in cooperative relay networks. In real wireless environments, as the channel of source-to-destination (SD) link varies with an increase in time, we can also obtain a diversity gain through

Outage Probability Analysis for Correlated Sources Transmission over Rician Fading Channels [PDF]

, 2013
In this paper, the outage probability of a Slepian-Wolf transmission system is analysed theoretically. We consider two correlated binary information sequences where bit-flipping model is adopted, where the the information bits of the second source are ...

Development and Evaluation of a Low‐Cost, Semi‐Automated Camera Trap for Surveying Bumble Bee Communities

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps are emerging as a useful tool for noninvasive insect monitoring; however, it remains unclear how to lure diurnal insects to traps, how to detect them upon arrival, and how camera‐based methods compare to conventional sampling. We developed a low‐cost, open‐source camera trap to monitor wild bumble bees in agricultural fields. We found that

Multihop Diversity - A Precious Source of Fading Mitigation in Multihop Wireless Networks

, 2011
The concept of multihop diversity is proposed, where all the nodes of a multihop link are assumed to have buffers for temporarily storing their received packets.
