Development and Optimization of Deep Learning Models for Weapon Detection in Surveillance Videos

open access: yesApplied Sciences, 2022
Weapon detection in CCTV camera surveillance videos is a challenging task and its importance is increasing because of the availability and easy access of weapons in the market. This becomes a big problem when weapons go into the wrong hands and are often

Detection and Classification of Different Weapon Types Using Deep Learning

open access: yesApplied Sciences, 2021
Today, with the increasing number of criminal activities, automatic control systems are becoming the primary need for security forces. In this study, a new model is proposed to detect seven different weapon types using the deep learning method.

Weapon Detection Using YOLO V3 for Smart Surveillance System

open access: yes, 2021
Every year, a large amount of population reconciles gun-related violence all over the world. In this work, we develop a computer-based fully automated system to identify basic armaments, particularly handguns and rifles.

THE CRETAN SLINGER AT WAR – A WEIGHTY EXCHANGE

open access: yesAnnual of the British School at Athens, 2012
Lead slingshots discovered on Cretan sites carry considerable weight regarding the nature of warfare on the island in the Late Classical and Hellenistic periods.

Piedra y plomo: la honda frente a los asentamientos fortificados del noreste de la península ibérica a partir del siglo III a. c. y su repercusión en los sistemas defensivos

open access: yes, 2017
The study and analysis of the complex system of moats around Los Castellazos site (Mediana de Aragon, Zaragoza) has made possible to identify the sling as one of the most popular weapon to attack and besiege fortifications during the Roman Republic.

Short Stories of Refugeedom: Encounters between Refugees, UNHCR, and the Australian Government, 1951–1975

open access: yesAustralian Journal of Politics &History, Volume 71, Issue 4, Page 718-734, December 2025.
This article draws upon individual confidential case files compiled by the UN Office for Refugees (UNHCR) between 1951 and 1975 to examine its response to refugees who requested protection and to analyse policy and practice in Australia as a country of resettlement.

SLING: using dynamic analysis to infer program invariants in separation logic [PDF]

open access: yesACM-SIGPLAN Symposium on Programming Language Design and Implementation, 2019
We introduce a new dynamic analysis technique to discover invariants in separation logic for heap-manipulating programs. First, we use a debugger to obtain rich program execution traces at locations of interest on sample inputs.

Deadly Lifeworlds Meet Palliative Politics: Struggle in Circulation

open access: yesAntipode, Volume 57, Issue 6, Page 2326-2348, November 2025.
Abstract This paper locates acute and ongoing crises of coloniality and ecology within struggles over circulation that are anchored in infrastructure. If infrastructure organises movement—including its constraint in carceral forms—then it is also a linchpin for materialising distinct regimes of motion (Nail 2020a; Marx in Motion: A New Materialist ...

The Flooding of Lagash (Iraq): Evidence for Urban Destruction Under Lugalzagesi, the King of Uruk and Umma

open access: yesGeoarchaeology, Volume 40, Issue 5, September/October 2025.
ABSTRACT High‐resolution remote sensing, magnetometry, and trench stratigraphy identify a significant flood event at Lagash (modern Tell al‐Hiba) during the late Early Dynastic period (ca. 2400–2350 BC). Satellite imagery and magnetometry reveal a 90‐meter‐wide meander belt—3–15 times broader than documented canals—adjacent to primary temple districts.
