An Integrated Data Acquisition System for Parachute Development and Qualification TestingStarbuck, Philip 10 1900 (has links)
ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, California / The development and qualification of personnel and cargo aerial delivery parachute systems present unique challenges to the instrumentation and data analysis engineers. Some of the areas that must be addressed include: a) system must be low in cost, b) system often has to be operated on ranges that have limited telemetry or other range instrumentation and support (i.e. commercial skydiving centers), c) system is often rigged and operated by parachute support personnel and test jumpers rather than instrumentation engineers, and d) system must be able to be reconfigured in the field to support a variety of test card requirements during a typical test day, e) data must be available for review and the system be prepared for the next test within a few minutes of parachute recovery, and f) system must withstand ground impact velocities as high as 50 ft/sec (15.24 m/sec) without damage. This paper describes such a system as it is being used for the development and qualification testing of a number of parachute systems for sport skydiving, military personnel, as well as cargo parachute systems. This modular system has been developed as a result of previous experience in other parachute development and qualification projects to address the need for a flexible Data Acquisition System (DAS) system that meets the above requirements. This paper describes some of the tools used to meet these requirements.

Forensik i fickformat : En forensisk analys av smartklockors och smartphones GPS-dataKrona, Ludwig, Henrysson, Henrysson January 2024 (has links)
This thesis delves into the realm of mobile forensics, specifically focusing on the forensic analysis of location-based data derived from smartwatches and smartphones. With the generation of wearable devices and the increasing reliance on personal electronics, understanding the differences and collaborative potential between these devices is imperative for forensic investigators. The study addresses three key research questions:1) How does geolocation differ between a smartphone and a smartwatch?2) How can information from smartphones and smartwatches collaborate to provide a more comprehensive picture in an investigation?3) Is the GPS/activity data from smartphones reliable evidence in legal cases?The research is positioned against existing studies that explore location-based health data, forensic analysis of IoT devices, and the relevance of smartwatch data in legal proceedings.The methodology used in the study is strategically chosen to offer a comprehensive understanding of the role and challenges associated with smartwatch and smartphone data in forensic contexts, such as experiments and non-structured interviews. By aligning with existing studies and leveraging experimental and interview-based approaches, the research aims to contribute valuable knowledge to the evolving field of mobile forensics. The outcomes of this study are expected to shed light on the use of location-based data in legal investigations, providing guidance for future practices and emphasizing the increasing centrality of these technologies in contemporary society.The results show that there is a difference between the devices, not only between the smartphones and smartwatches but also between the different brands. What significance this plays will be discussed and useful conclusions inferred. / Denna studie undersöker området mobil forensik, med särskilt fokus på den forensiskaanalysen av geolokaliserings data från smartklockor och smartphones. På grund av denökade framväxten av bärbara enheter och det ökande beroendet av personlig elektronikär det viktigt för forensiska utredare att förstå de skillnaderna och samarbetsmöjlighetersom finns mellan dessa enheter. Studien behandlar tre centrala forskningsfrågor:- Hur skiljer sig geolokalisering mellan en telefon och en smartklocka?- Hur kan information från smartphones och smartklockor samverka för att ge enmer heltäckande bild i en utredning?- Är GPS-/aktivitetsdata från smarttelefoner tillförlitliga bevis i rättsfall?Forskningen är positionerad mot befintliga studier som undersöker platsbaseradehälsodata, forensisk analys av IoT-enheter och relevansen av data från smartklockor irättsliga sammanhang.Den metodologi som används i studien är strategiskt vald för att erbjuda en omfattandeförståelse av rollen och utmaningarna associerade med data från smartklockor ochsmartphones i forensiska sammanhang. Metoderna inkluderar experiment ochostrukturerad intervju. Genom att anpassa sig till befintliga studier och utnyttjaexperimentella och intervjubaserade tillvägagångssätt, syftar studien till att bidra medvärdefull kunskap till det växande fältet. Resultaten av denna studie förväntas belysaanvändningen av geolokaliserings data i rättsliga utredningar, ge vägledning förframtida praxis och betona den ökande centraliteten av dessa teknologier i dagenssamhälle. Resultaten visar att det finns skillnader mellan enheterna, inte bara mellansmartphones och smartklockor utan också mellan olika märken. Vilken betydelse dettahar kommer att diskuteras och användbara slutsatser dras.

Das E-Lastenrad als Alternative im städtischen Wirtschaftsverkehr. Determinanten der Nutzung eines „neuen alten“ FahrzeugkonzeptsGruber, Johannes 05 March 2021 (has links)
Elektrifizierte Lastenfahrräder werden als ein Lösungsansatz für die wachsenden Herausforderungen des städtischen Wirtschaftsverkehrs gesehen. Fokus dieser Arbeit ist eine Abschätzung des Einsatzpotenzials dieses Fahrzeugkonzepts unter Betrachtung von konzeptionellen, verkehrlichen und wirtschaftlichen Aspekten. Als kumulative Dissertation enthält sie fünf Fachartikel, gruppiert zu drei Forschungsbeiträgen.
Im ersten Forschungsbeitrag wird erörtert, wie erfolgversprechend das E-Lastenrad, eine Neuauflage des alten Konzepts Lastenfahrrad, in einem Markt mit ersten Anwendern (Kurierdienstleistung) ist. Die Auftragsstruktur im Stadtkuriergeschäft bietet ein substanzielles Marktpotenzial für E-Lastenräder, allerdings erschwert die Positionierung zwischen zwei etablierten Modi (Pkw und Fahrrad) den Markteintritt.
Der zweite Teil der Analyse weitet den Blick auf alle Branchen und bietet eine strukturierte Beschreibung der verschiedenartigen Einflussfaktoren (Treiber und Hemmnisse), die auf die Lastenradnutzung im städtischen Wirtschaftsverkehr wirken. Als relevante Entscheidungskriterien konnten identifiziert werden: fahrzeugseitige Aspekte, Strukturen und Prozesse des adoptierenden Unternehmens, Einstellungen der Entscheider*innen, weiche Faktoren sowie regulative und räumliche Rahmenbedingungen.
Der dritte Beitrag thematisiert die operative Eignung des E-Lastenrads, indem seine Fahrtzeiten einem Pkw gegenübergestellt werden. Bei Strecken bis zu 3 km sind beide Modi nahezu gleich schnell. Die Hälfte aller Fahrten bis 20 km Distanz würde bei einem Wechsel vom Pkw zum Lastenrad höchstens 2–10 min länger dauern (ohne Berücksichtigung der Parksuchzeit). Bereits kleine Änderungen an den Verkehrsbedingungen könnten noch bestehende Vorteile des Pkw spürbar verringern.
Insgesamt erweitert die Arbeit maßgeblich das Wissen zu einem „neuen alten“ Fahrzeugkonzept, dem ein Potenzial zur Auflösung von bislang auf das Automobil hin ausgerichteten Systemen beigemessen wird. / Shifting trips to electric cargo bikes is one possible solution to deal with the growing challenges of urban commercial transport. This thesis combines conceptual, transport-related, and economic aspects as a foundation to assess the feasibility of this vehicle concept for freight and service trips. It contains five scientific papers, which provide three research contributions.
The first contribution identifies the potentials of electric cargo bikes among first users (i.e., courier logistics services). Electric cargo bikes are an updated and re-envisioned version of freight bicycles. The features of point-to-point courier logistics assignments offer a substantial market opportunity for electric cargo bikes. However, being positioned between two established modes (i.e., car and bicycle) handicaps the market entry of cargo bikes.
For the second contribution, the scope was widened to include all business sectors. A structured description is presented of the various determinants (i.e., drivers and barriers) affecting commercial cargo bike use. Among these were vehicle-specific factors, structures and practices of the company, attitudes of decision-makers, soft factors, regulatory frameworks, and spatial conditions.
The third contribution explores the travel time differences between electric cargo bikes and cars for commercial trips. For trip distances of up to 3 kilometers, the travel times of both modes largely overlap. Half of all trips up to 20 kilometers would take only a maximum of 2 to 10 minutes longer by electric cargo bike (excluding the additional time for finding a parking spot). Small modifications in traffic could have considerable effects in reducing the current travel time advantages of cars.
Consequently, this dissertation contributes towards the state-of-research by expanding the scientific knowledge of a type of vehicle that has the potential to disrupt car-dependent transportation systems.
