Att kommunicera rummets varierande funktion genom 3D-visualiseringar är ett examensarbete i informationsdesign med inriktning rumslig gestaltning. Uppdraget kommer från Husmuttern AB som arbetar med huskoncept som sedan ska leda till produktion av modulhus. Syftet med arbetet har varit att studera hur en 3D-modell bör utformas för att kommunicera ett rums varierande funktion. Detta för att veta hur jag ska visualisera en undervisningssal i ett modulhus. För att arbeta fram en 3D-modell som uppfyller dessa krav krävs det att studera kommunikation mellan parter, bildens egenskaper, rummets form och färg, detta med stöd i litteratur, forskning och användartester. Därefter kunde en modell arbetas fram som kunde kommunicera en undervisningssal i ett modulhus. Genom användartesterna visade det sig att det är bra med en modell som fokuserar på modulhusets grund men också att ha med inredning för att visa funktionen. Det resulterade i en modell som innehöll husgrunden på en halva och realistisk inredning på den andra halvan men i samma modell. Genom litteratur och tidigare forskning blev resultatet för visualiseringar att det är ofta som 3D-modeller används. I utformningen bör detaljer uteslutas och verklighetstrogna vyer undvikas. Fokus bör ligga på det väsentliga då det annars blir för mycket att ta in för betraktaren och budskapet går förlorat, samt att verklighetstrogna skisser upplevs som färdigutvecklade. Det resulterade i en skissartad modell med avskalad inredning för att visa rummets funktion. Att kommunicera rummets varierande funktion genom 3D-visualiseringar is a thesis in information design with orientation in spatial design. The assignment comes from the company Husmuttern AB who work with house concept that will lead to production of module housing. The purpose has been to study how a 3D- visualisation should be formed to communicate rooms varying functions. All this so that I will know how to visualize a classroom in a module housing. To be able to come up with a 3D-model that have this quality it was requires to study communication between two parties, properties of the image, shape and color of the room, with the help of literature, previous research and user tests. Then it was possible to come up with a model that could communicate a classroom constructed in module. Through the user tests it was shown to be preferable with a model that focuses on the basic units of the module housing but that also has some realistic decor to show some function. All this resulted in a model which includes the basic units of the module on one half and realistic décor on the other half in the same model. Thanks to literature and previous research the result for visualization was that it is common to use 3D-modells. In the modeling details and realistic views should be avoid. The focus should be on the essential or it will be too much for the viewer to take in and the message gets lost, but also that to realistic models were considered to be fully complete. All this resulted in a sketchy model with a small amount of décor to show the rooms function

Knowledge-Intensive Fusion for Situational Awareness: Band Sultan Dam Failure Scenario

This report provides a detailed specification of a humanitarian relief scenario involving significant civil-military cooperation. The scenario aims to highlight some challenges and opportunities for semantic integration and knowledge processing in support of humanitarian relief efforts undertaken against a backdrop of military conflict. The scenario depicts an earthquake and associated flood event occurring in Afghanistan at the time of the US-led coalition effort to displace the former Taliban regime. The flood event occurs as a secondary phenomenon to the earthquake and precipitates a full-scale humanitarian relief effort co-opting the resources of both humanitarian and military agencies. This scenario will serve to showcase the capabilities of the AKTiveSA TDS with respect to enhanced situation awareness and improved information fusion. Such capabilities depend on the ability to exploit multiple sources of information and sophisticated query capabilities in order to expedite the dissemination of relevant information to executive agencies in a timely and appropriate fashion. The scenario narrative draws attention to some of the information requirements demanded by military and humanitarian decision makers in the context of complex emergency situations. It also serves to illustrate the critical knowledge processing capabilities of agents with respect to the assessment of disaster situations and relief effort planning. Finally, the scenario provides an indication of the requirements for visualization and interaction that should be afforded to end-user agents in order to optimise their exploitation of system capabilities. This report also provides background information about the Standard Operating Procedures (SOPs) of humanitarian agencies with respect to disaster relief and reviews guidelines on the nature of civil-military coordination in the context of disaster relief efforts in conflict situations

Operationalized Intent for Improving Coordination in Human-Agent Teams

With the increasing capabilities of artificial intelligent agents (AIAs) integrated into multi-agent systems, future concepts include human-agent teams (HATs) in which the members perform fluidly as a coordinated team. Research on coordination mechanisms in HATs is largely focused on AIAs providing information to humans to coordinate better (i.e. coordination from the AIA to the human). We focus on the compliment where AIAs can understand the operator to better synchronize with the operator (i.e. from the human to the AIA). This research focuses specifically on AIA estimation of operator intent. We established the Operationalized Intent framework which captures intent in a manner relevant to operators and AIAs. The core of operationalized intent is a quality goal hierarchy and an execution constraint list. Designing a quality goal hierarchy entails understanding the domain, the operators, and the AIAs. By extending established cognitive systems engineering analyses we developed a method to define the quality goals and capture the situations that influence their prioritization. Through a synthesis of mental model evaluation techniques, we defined and executed a process for designing human studies of intent. This human-in-the-loop study produced a corpus of data which was demonstrated the feasibility of estimating operationalized intent

Cooperative Unmanned Aerial Surveillance Control System Architecture

Intelligence, surveillance and reconnaissance (ISR) is a high-demand Department of Defense mission performed by unmanned aircraft systems (UASs) at the tactical and theater levels. Coordinating UASs through cooperative control offers the advantages of persistence, distributed and adaptable sensor coverage, and reduced revisit time on points of interest. The purpose of this thesis is to apply systems engineering principles to the problem of developing a flexible, common control system for cooperative UAS surveillance at the tactical level. The AFIT team developed a concept of operations (CONOPS) encompassing various users and surveillance tasks. The team then used the scenarios in the CONOPS to build a conceptual architecture. Concurrently, the team constructed a developmental test system that closely resembled the architecture and successfully conducted flight tests of multiple aircraft. The team then used this architecture and the prototype system to identify significant technical risks and future research areas to be explored prior to the development of an operational system

Adoption of vehicular ad hoc networking protocols by networked robots

This paper focuses on the utilization of wireless networking in the robotics domain. Many researchers have already equipped their robots with wireless communication capabilities, stimulated by the observation that multi-robot systems tend to have several advantages over their single-robot counterparts. Typically, this integration of wireless communication is tackled in a quite pragmatic manner, only a few authors presented novel Robotic Ad Hoc Network (RANET) protocols that were designed specifically with robotic use cases in mind. This is in sharp contrast with the domain of vehicular ad hoc networks (VANET). This observation is the starting point of this paper. If the results of previous efforts focusing on VANET protocols could be reused in the RANET domain, this could lead to rapid progress in the field of networked robots. To investigate this possibility, this paper provides a thorough overview of the related work in the domain of robotic and vehicular ad hoc networks. Based on this information, an exhaustive list of requirements is defined for both types. It is concluded that the most significant difference lies in the fact that VANET protocols are oriented towards low throughput messaging, while RANET protocols have to support high throughput media streaming as well. Although not always with equal importance, all other defined requirements are valid for both protocols. This leads to the conclusion that cross-fertilization between them is an appealing approach for future RANET research. To support such developments, this paper concludes with the definition of an appropriate working plan

STS-2 second space shuttle mission: Shuttle to carry scientific payload on second flight

The STS-2 flight seeks to (1) fly the vehicle with a heavier payload than the first flight; (2) test Columbia's ability to hold steady attitude for Earth-viewing payloads; (3) measure the range of payload environment during launch and entry; (4) further test the payload bay doors and space radiators; and (5) operate the Canadian-built remote manipulator arm. The seven experiments which comprise the OSTA-1 payload are described as well as experiments designed to assess shuttle orbiter performance during launch, boost, orbit, atmospheric entry and landing. The menu for the seven-day flight and crew biographies, are included with mission profiles and overviews of ground support operations
