Ljudövervakningssystem för smarta städer : Designriktlinjer i enlighet med svensk lagstiftning

Skiöld, Martin, Näslund Eriksson, Tobias January 2016 (has links)
This paper investigates how audio monitoring systems should be designed, in the context of smart cities and in accordance with Swedish legislation. Audio monitoring for smart cities is promising and have previously shown great potential. However its opportunities are still relatively unexplored. ShotSpotter is one of several examples of audio monitoring in the context of smart cities. In the US only, the system has successfully been used to alert and locate shootings in over 90 cities. However, the technology is surrounded by controversies and there has been debate whether audio monitoring systems are compatible with law. Compatibility is critical since incompatibility could result in severe sanctions. Research related to this paper has been conducted according to the Design Science research strategy. The research resulted in design guidelines for audio monitoring systems, for law enforcement purposes, in accordance with Swedish law. The design guidelines are based upon existing audio monitoring systems, previous research and empirical data. The empirical data consists of 12 interviews with experts in law, phonetics and digital forensics. Additionally, the design guidelines have been evaluated by an expert in a criteria-based evaluation interview. Results of the research shows that it is, in fact, possible to design audio monitoring systems, in the context of smart cities, in accordance with Swedish legislation. The design guidelines can be applied in the development of audio monitoring systems with law enforcement purposes. With some modification, they can also be used for audio monitoring systems with other purposes. / Uppsatsen syftar till att undersöka hur ljudövervakningssystem inom ramen för smarta städer- konceptet bör utformas i enlighet med svensk lagstiftning. Ljudövervakning för smarta städer har visat på stor potential och ännu är dess möjligheter outforskade. ShotSpotter är ett av flera exempel på ljudövervakning inom ramen för smarta städer. Systemet har med framgång använts för att uppmärksamma och lokalisera skottlossningar i över 90 amerikanska städer. Det råder dock debatt huruvida ljudövervakningssystemet är kompatibelt med lagstiftning. Denna kompatibilitet är kritisk då det motsatta kan resultera i stränga påföljder och därmed utgöra direkta hinder för implementation. Forskning i relation till uppsatsen har genomförts inom ramen för forskningsstrategin Design Science. Forskningsprocessen har mynnat ut i designriktlinjer för hur ett ljudövervakningssystem med brottsbekämpande syfte bör utformas i enlighet med svensk lagstiftning. Designriktlinjerna baseras på befintliga ljudövervakningssystem, tidigare forskning och omfattande empiriskt underlag. Det empiriska underlaget utgörs av 12 intervjuer med olika typer av experter inom juridik, fonetik och IT- forensik. Designriktlinjerna har med framgång utvärderats i en kriteriebaserad expertintervju. Av forskningsresultatet att döma är det möjligt att utforma ljudövervakningssystem för smarta städer i enlighet med svensk lagstiftning. De framtagna designriktlinjerna kan användas vid utveckling av ljudövervakningssystem med brottsbekämpande syfte. Med viss modifikation kan de även användas för ljudövervakningssystem med andra syften.

Active Shooter Mitigation for Open-Air Venues

Braiden M Frantz (8072417) 04 August 2021 (has links)
<p>This dissertation examines the impact of active shooters upon patrons attending large outdoor events. There has been a spike in shooters targeting densely populated spaces in recent years, to include open-air venues. The 2019 Gilroy Garlic Festival was selected for modeling replication using AnyLogic software to test various experiments designed to reduce casualties in the event of an active shooter situation. Through achievement of validation to produce identical outcomes of the real-world Gilroy Garlic Festival shooting, the researcher established a reliable foundational model for experimental purposes. This active shooter research project identifies the need for rapid response efforts to neutralize the shooter(s) as quickly as possible to minimize casualties. Key findings include the importance of armed officers patrolling event grounds to reduce response time, the need for adequate exits during emergency evacuations, incorporation of modern technology to identify the shooter’s location, and applicability of a 1:548 police to patron ratio.</p>
