The Location of LPG Filling Stations and Potential Risks of Incidents

open access: yesCommunications, 2016
The risk of unsuitable placement of LPG (i.e. Liquid Petroleum Gas) propane-butane filling stations in densely populated areas or in the immediate vicinity of busy roads may have, in the event of fire or explosion, incalculable consequences in terms of ...

Performance analysis for a stabilized multi-channel slotted ALOHA algorithm [PDF]

open access: yes, 2003
We study slotted ALOHA with multiple random access channels, the so called multi-channel ALOHA (MC-ALOHA). It is well known that single-channel ALOHA (SC-ALOHA) is unstable. Not surprisingly, MC-ALOHA is also unstable.

GOVERNING THE CLOUD: Infrastructural Statecraft and the Political Ecology of Digital Expansion in Oregon

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Oregon's wave of data center and semiconductor projects shows how cloud capitalism reorganizes resource systems and territorial governance. Examining Amazon, Google, and Intel, the article traces how fiscal incentives, utility programs, and land‐use instruments are recalibrated to secure hyperscale loads.

Exploiting Capture Effect in Frameless ALOHA for Massive Wireless Random Access

open access: yes, 2014
The analogies between successive interference cancellation (SIC) in slotted ALOHA framework and iterative belief-propagation erasure-decoding, established recently, enabled the application of the erasure-coding theory and tools to design random access ...

Adaptive-opportunistic Aloha: A media access control protocol for unmanned aerial vehicle–wireless sensor network systems

open access: yesInternational Journal of Distributed Sensor Networks, 2016
Recognizing that data collection in a unmanned aerial vehicle–wireless sensor network system is significantly different from that in a conventional wireless sensor network system, we propose a media access control protocol called adaptive-opportunistic ...

On the Aloha throughput-fairness tradeoff [PDF]

open access: yesIEEE Transactions on Information Theory, 2017
A well-known inner bound of the stability region of the slotted Aloha protocol on the collision channel with n users assumes worst-case service rates (all user queues non-empty). Using this inner bound as a feasible set of achievable rates, a characterization of the throughput--fairness tradeoff over this set is obtained, where throughput is defined as

Three‐Dimensional Analytical Model of a Free‐Standing Square Rocking Column

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 8, Page 1710-1727, 10 July 2026.
ABSTRACT A three‐dimensional analytical two‐degree‐of‐freedom (2DOF) model is developed to describe the bounded rocking response of free‐standing rigid square columns subjected to bidirectional seismic excitation. The formulation extends Housner's classical planar theory by deriving the full three‐dimensional equations of motion for a column ...

Modeling the Consequences Release of Cyanogen agents in Bushehr Nuclear Power Plant Neighborhood Using PHAST, ALOHA and WISER Software

open access: yesSalāmat-i kār-i Īrān, 2020
Background and purpose Many efforts have been made to use chemical components as weapons throughout history until the Germans first employed chlorine gas cylinders in April 1915 at Ypres Belgium against French and Canadian soldiers.
