Ubique Vigilans: Verksam överallt : Telekrigsförmåga i Amfibiebataljonen / Ubique Vigilans: Active Everywhere : Electronic Warfare capability within the Amphibious Battalion

Kahlin, Magnus January 2010 (has links)
<p>Det svenska försvarets övergång till insatsförsvar och internationella insatser har lett till omfattande förändringar av Försvarsmakten. Inom ramen för detta är ny amfibiebataljon under framställning. Denna bataljon bör agera med telekrigsförmåga och därmed undersöks vilken typ av system bör vara lämpligt för amfibiebataljon 2014. Initialt så framställs en genomgång av elektronisk krigföring för att skapa förståelse för ämnet och telekrigsförmågans utveckling i både Armén och Marinen. Amfibiebataljon 2014 presenteras för att beskriva förbandet som amfibieregementet skall ansvara för. För att förstå det sammanhang i vilket amfibiska styrkor skall använda sig av telekrigssystem, så beskrivs tre amfibiska scenarier för att möjliggöra en kommande analys. En intervju med tre nyckelpersoner inom det svenska försvaret förs fram för att säkerställa att aktuell information används i uppsatsen. Analysdel av uppsatsen kommer att baseras på de olika telekrigssystemen med en metod att utvärdera dessa från Försvarsmakten grundläggande förmågor. Därefter kommer de system som skall ha utvärderats på grunder av för- och nackdelar sättas i kontext i samband med de scenarier som har lagts fram. Målet är att ta reda på vilket system som är till nytta för amfibiebataljon, samt för- och nackdelarna med ett sådant system. Resultaten visar att ett medelstort system bör användas av amfibiebataljon på grund av sin förmåga till verkan samtidigt som den uppfyller krav på skydd och rörlighet. Dessutom bör ett lätt telekrigssystem användas av amfibiebataljonen på grund av dess kapacitet inom rörlighet och underrättelseinhämtningskapacitet.</p> / <p>The Swedish Armed Forces transition to a force specified against international missions has brought extensive transformations of the armed forces. As part of this a new amphibious battalion 2014 is in the progress of being organized. This battalion should act with electronic warfare capabilities and thus, this essay will investigate what kind of system should be appropriate for the amphibious battalion. The essay begins with a review of electronic warfare in order to create an understanding in general as well as its development in both the Army and the Marine forces. Amphibious battalion 2014 is also presented to describe the upcoming unit which the amphibious regiment shall be responsible for. To understand the context in which amphibious forces shall make use of electronic warfare systems, descriptions of three amphibious warfare scenarios are presented to allow an upcoming analysis. An interview with three key personnel within the Swedish Armed Forces is brought forward to ensure that current information is used in the essay. The analysis part of the essay is based on the various electronic warfare systems with a method of evaluating these from the Armed Forces essential abilities. Thereafter, the systems will be evaluated on the basis of the produced pros and cons in correlation with the operation scenarios that has been presented. The goal is to find out which system is of use for the amphibious battalion, and the pros and cons of such a system. The results indicates that a medium-sized system should be used by the amphibious battalion because of its ability for effect while it meets demands for protection and mobility. Also, a light electronic warfare systems should be used by the amphibious battalion because of its capacity in mobility and intelligence gathering capability.</p>

Design of a prototype autonomous amphibious WHEGS robot for surf-zone operations

Ward, Jason L. 06 1900 (has links)
The Small Robot Initiative at the Naval Postgraduate School (NPS) has spent several years in development based on the Foster Miller lemmings platform. This platform, in conjunction with a commercial off-the-shelf (COTS) control architecture, is capable of autonomous, land based waypoint navigation, self orientation, and rudimentary obstacle avoidance. It can receive waypoint information, manual control input, and transmit video and audio information back to a control station via 802.11 wireless communication. The introduction of the WHEGS design, developed at Case Western Reserve University, and a modified version of the COTS control system will provide a platform with greater speed, mobility and versatility. This thesis developed a prototype WHEGS vehicle and integrated the control system with improvements in the navigation routine through the addition of a dead reckoning sensor and calculation function. Although the mechanical design proved to be highly inefficient and unable to propel itself, the control system was successful, allowing integration with a more robust mechanical design from Case Western Reserve University. Follow on development and research will lighten the body through the use of carbon fiber and test the robots ability to maneuver effectively in the surf-zone.

Where the River Flows Fast

Barei, Andrea January 2011 (has links)
Kashechewan, a flood-prone remote First Nation in northern Ontario, is the focus of this thesis. It is an exploration into the factors that have contributed to the community’s decline and current state. By looking at how these factors influence built form, the principles, possibilities, and concepts that are latent within it are used to re-establish ways in which the people can view, value, and act upon the land to create lasting change. The discussion has larger implications about how we, as Canadians, live with the land and built forms, and react to one another both as a collective, and as individuals. It is an attempt to dissolve the distinction between ‘aboriginal’ and ‘colonizer’ to open up greater design possibilities. Composed as a series of explorations into the physical and spiritual form of the community, this thesis weaves together three parts of its larger story connected with the thread of narrative poem. Part I opens a discourse that considers the impact of the system and establishment of Aboriginal Reserves on the community. Part II explores the notion of remoteness alongside methods of movement and transportation of people and materials. Part III engages the ephemeral, discussing memory and the meaning of transient moments. Stemming from these streams of exploration, three individual designs are proposed. The first explores flood-resilient architecture as a sensitive response to the river and engages the future expansion of the community beyond the walls of the dike. The second envisions an integration of movement into a centralized community hub. The third lays out an approach to abandoning the site while preserving its sacred spaces. In each case, the design explores built form as a tool for fusing back together the spirit of the land and the narrative of the people. Through the metaphor of flooding as a conversation between the light and the dark, this thesis looks at the history of abuse between aboriginal and colonizer, and the current abuse of substance and soul from which an architectural premise moves forward. The thesis attempts to embrace the complexity and difficulty of designing with such inherent obstacles to overcome by taking inspiration from the simple and sublime beauty of the place and distilling it into built form.

A Study of Omnidirectional Quad-Screw-Drive Configurations for All-Terrain Locomotion

Freeberg, Jon T. 26 October 2010 (has links)
Double-screw vehicles have been developed to operate in soft, wet terrains such as marsh, snow, and water. Their exceptional performance in soft and wet terrains is at the expense of performance on rigid terrains such as pavement. Furthermore, turning can be difficult because the method of turning varies depending on the terrain. Therefore, in this study, several different quad-screw-configurations were proposed and tested to improve upon double-screw vehicles. A test-bed was developed which could easily be converted into each quad-screw-configuration for testing on a variety of surfaces (grass, dirt, sand, clay, marsh, snow, gravel, pavement, and water). In addition, a force-vector analysis was performed for each screw-configuration to predict and understand performance in different terrains. From the testing and analysis, the inline-screw configuration was the most versatile because it was omnidirectional on all surfaces but water and pavement. Regardless, it was fully capable of navigating water, both on the surface and submerged, and pavement by rotating about its center.

Includes supplementary material. / CAPSTONE PROJECT REPORT / System Engineering and Analysis Cohort 18A and Temasek Defense Systems Institute / Approved for public release, distribution unlimited / The aging Whidbey Island and Harpers Ferry class ships, LSD-41 and 49 respectively, comprise just over one third of the amphibious navy. However, a solution to the capability gap created by the loss of these ships is needed to maintain the effectiveness of the amphibious fleet across a broad spectrum of mission areas. This research effort considers future ship designs and fleet architectures to meet the capability gaps left by the decommissioning of the LSD-41 and 49 class ships. With respect to lift capacity, performance capability, cost and a risk assessment, the analysis showed the LPD-17 or a LSD(X) approximately 30% larger than the existing classes to be acceptable replacement classes. This analysis also supports further research to determine the most robust fleet architecture apart from the current eleven LHA or LHD, eleven LPD and eleven LSD paradigm.
