An Information-Motivated Exploration Agent to Locate Stationary Persons with Wireless Transmitters in Unknown Environments

Unmanned Aerial Vehicles (UAVs) show promise in a variety of applications and recently were explored in the area of Search and Rescue (SAR) for finding victims. In this paper we consider the problem of finding multiple unknown stationary transmitters in a discrete simulated unknown environment, where the goal is to locate all transmitters in as short a time as possible. Existing solutions in the UAV search space typically search for a single target, assume a simple environment, assume target properties are known or have other unrealistic assumptions. We simulate large, complex environments with limited a priori information about the environment and transmitter properties. We propose a Bayesian search algorithm, Information Exploration Behaviour (IEB), that maximizes predicted information gain at each search step, incorporating information from multiple sensors whilst making minimal assumptions about the scenario. This search method is inspired by the information theory concept of empowerment. Our algorithm shows significant speed-up compared to baseline algorithms, being orders of magnitude faster than a random agent and 10 times faster than a lawnmower strategy, even in complex scenarios. The IEB agent is able to make use of received transmitter signals from unknown sources and incorporate both an exploration and search strategy

Hybrid intelligent decision support system for distributed detection based on ad hoc integrated WSN & RFID

This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonThe real time monitoring of environment context aware activities, based on distributed detection, is becoming a standard in public safety and service delivery in a wide range of domains (child and elderly care and supervision, logistics, circulation, and other). The safety of people, goods and premises depends on the prompt immediate reaction to potential hazards identified in real time, at an early stage to engage appropriate control actions. Effective emergency response can be supported only by available and acquired expertise or elaborate collaborative knowledge in the domain of distributed detection that include indoor sensing, tracking and localizing. This research proposes a hybrid conceptual multi-agent framework for the acquisition of collaborative knowledge in dynamic complex context aware environments for distributed detection. This framework has been applied for the design and development of a hybrid intelligent multi-agent decision system (HIDSS) that supports a decentralized active sensing, tracking and localizing strategy, and the deployment and configuration of smart detection devices associated to active sensor nodes wirelessly connected in a network topology to configure, deploy and control ad hoc wireless sensor networks (WSNs). This system, which is based on the interactive use of data, models and knowledge base, has been implemented to support fire detection and control access fusion functions aimed at elaborating: An integrated data model, grouping the building information data and WSN-RFID database, composed of the network configuration and captured data, A virtual layout configuration of the controlled premises, based on using a building information model, A knowledge-based support for the design of generic detection devices, A multi-criteria decision making model for generic detection devices distribution, ad hoc WSNs configuration, clustering and deployment, and Predictive data models for evacuation planning, and fire and evacuation simulation. An evaluation of the system prototype has been carried out to enrich information and knowledge fusion requirements and show the scope of the concepts used in data and process modelling. It has shown the practicability of hybrid solutions grouping generic homogeneous smart detection devices enhanced by heterogeneous support devices in their deployment, forming ad hoc networks that integrate WSNs and radio frequency identification (RFID) technology. The novelty in this work is the web-based support system architecture proposed in this framework that is based on the use of intelligent agent modelling and multi-agent systems, and the decoupling of the processes supporting the multi-sensor data fusion from those supporting different context applications. Although this decoupling is essential to appropriately distribute the different fusion functions, the integration of several dimensions of policy settings for the modelling of knowledge processes, and intelligent and pro-active decision making activities, requires the organisation of interactive fusion functions deployed upstream to a safety and emergency response.Saudi government, represented by the Ministry of Interior and General Directorate of Civil Defenc

Women in a Man\u27s War: The Employment of Female Agents in the Special Operations Executive, 1940-1946

The Special Operations Executive (SOE) was established in 1940 under the directive of Winston Churchill to collaborate with resistance groups, divert enemy military advances and “set Europe ablaze!” As the world’s armies marched across the globe once more, dozens of women found themselves deployed by the SOE to act as agents and combatants behind enemy lines; effectively challenging traditional gender roles in war. While World War II has often been perceived as a man’s war, the direct and violent participation of women in various theaters of the war have been largely overlooked. Rather, women during WWII have been recalled as factory workers, nurses and mothers, all of which were crucial components in the war effort, but nonetheless conscribe to the traditional notions of the gendered war work hierarchy. In this hierarchy, superiority was defined as soldiering, but only for the men of a nation. As societal norms excluded women from this wartime role, nursing was the valued feminine position. Yet, female agents of the SOE were employed and valued for their claims to femininity as the organization co-opted stereotypes of womanhood to deceive enemy forces in occupied territory. This thesis explores the overarching question of what it means to be a woman in war, a perceived male-dominated sphere of influence. Even though research has expanded extensively on this important question, female SOE agents in France present a unique case study in which women were not only legitimized as combatants by a government, but were also recognized for the advantages of their femininity. Drawing from SOE documentation, personnel files, and personal accounts from agents, this thesis illustrates the elite combatant status of female SOE agents in France. By tracking their experience from recruitment, training, war work, and imprisonment, reveals how both their actions and legal terminology defined these women as combatants, although unlawful. The fascination revolving around female agents has persisted over the past seventy-nine years since the inception of the SOE. That said, the way in which these elite women have been recognized has shifted from combatants to spies, a subtle but important distinction in terms of wartime gender roles

Cross Connections: Online Activism, Real World Outcomes

This research paper examines the role of the Internet as it relates to the development of social movements and political protest in the ‘physical’ world. It also analyses the role of independent media and reporting methodologies used by activists and net-artists. The emergence of online activism and an emphasis on collaboration, information sharing and open source tools also had a significant impact on new media arts discussions and aesthetics. The refugee activist movement in Australia is a key case study in this thesis, as it is an excellent example of how activists have used the Internet and WWW to garner support within the community and to engage people to come to protests. In addition, activists at the protests have reported these events on the WWW and this subject has also had a resounding impact within the context of contemporary and media arts. The implications of identity online is a major factor in constructing the arguments in this thesis, as the relationship between ‘real’ and ‘virtual’ space is explored in detail as it relates to personal identity and online community

Restructuring Broadcasting Policies in Taiwan: Managing Cultural Identity in a Recently-Democratic Society

[[abstract]]This study examined some ofthe most commonly cited factors that affect the reforms of broadcast policies governing developing countries' broadcast media, and how these factors influence the establishment ofTaiwan's cultural sphere. The subjects for this study were key persons from government, educational, economic and television production sectors involved in the planning and implementation of broadcast policies in Taiwan. They included public officials responsible for broadcasting policy, educators and community activists, media policy analysts and television manager and producers. The data ofthe study were collected through informant interviewing and document review. Within the Government Information Office, a number of public officials were consulted. Beyond the GIO, other media sources and agencies provided important documentation in the form of surveys and reports. The investigation was carried out in Taiwan over a period offour months between April and August 2004. The results ofthis research reveal that in spite of the expectation that television should be used to help foster and promote national culture, Taiwan has not successfully developed and implemented policies to ensure the achievement ofthis policy goal. The research findings indicate that the production ofdomestic television programs are undermined through a colonized broadcasting system. Despite the influence offoreign broadcasters over the cultural production, the case study also shows that the role of civil society group in restructuring television industry is made manifest by resistance to private groups' intervention in the broadcasting policy process. This study has practical implications for the formulation ofnational broadcasting policies in recently-democratic countries and other countries facing similar dilemmas. The broadcasting policy analysis conducted in this study focused in part on the commercialism offoreign television programs, which severely threatens indigenous cultures around the world. In an era of globalization, the preservation oflocal identity is a challenging goal for broadcasting policy planners since many states have embraced neo-liberalism approaches to the communication sector. Within a situation ofglobal-local nexus, the study concludes that protection ofnational cultural spheres will be the important policy agenda for both policy makers and researcher for years to come.[[notice]]補正完

Wearable computing and contextual awareness

Thesis (Ph.D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 1999.Includes bibliographical references (leaves 231-248).Computer hardware continues to shrink in size and increase in capability. This trend has allowed the prevailing concept of a computer to evolve from the mainframe to the minicomputer to the desktop. Just as the physical hardware changes, so does the use of the technology, tending towards more interactive and personal systems. Currently, another physical change is underway, placing computational power on the user's body. These wearable machines encourage new applications that were formerly infeasible and, correspondingly, will result in new usage patterns. This thesis suggests that the fundamental improvement offered by wearable computing is an increased sense of user context. I hypothesize that on-body systems can sense the user's context with little or no assistance from environmental infrastructure. These body-centered systems that "see" as the user sees and "hear" as the user hears, provide a unique "first-person" viewpoint of the user's environment. By exploiting models recovered by these systems, interfaces are created which require minimal directed action or attention by the user. In addition, more traditional applications are augmented by the contextual information recovered by these systems. To investigate these issues, I provide perceptually sensible tools for recovering and modeling user context in a mobile, everyday environment. These tools include a downward-facing, camera-based system for establishing the location of the user; a tag-based object recognition system for augmented reality; and several on-body gesture recognition systems to identify various user tasks in constrained environments. To address the practicality of contextually-aware wearable computers, issues of power recovery, heat dissipation, and weight distribution are examined. In addition, I have encouraged a community of wearable computer users at the Media Lab through design, management, and support of hardware and software infrastructure. This unique community provides a heightened awareness of the use and social issues of wearable computing. As much as possible, the lessons from this experience will be conveyed in the thesis.by Thad Eugene Starner.Ph.D

Space, people, networks:exploring the relationship between built structures and seamless wireless communication infrastructures

In this thesis, I investigate wireless communication from an architectural perspective. I am using design prototypes to explore possibilities for interaction and designing with wirelessness in mind. The public primarily regards wireless networking technology as a technical infrastructure that should provide a seamless flow of information across a network of base stations, access points and mobile devices. From this perspective, wireless infrastructure is evaluated in terms of network availability and speed, and is continuously optimised. Researchers explored some other perspectives on wireless communication technology: they used computational spatial analysis to measure signal propagation in space. Some ethnographic studies explored its effect on the use of public space. Wireless connectivity was also explored through the philosophical framework of radical empiricism. All this points to the fact that wireless network infrastructure is a complex topic, spanning multiple fields of expertise and interest (engineering, architecture, urban studies but also sociology and philosophy). It is rarely explored from a plural perspective, as each study typically focuses on the one aspect within its expertise. I propose a more complex view of wireless connectivity, encompassing these different perspectives through an intellectual framework that is based on the notion of architecturality. Architecturality, a property common to all architecture but exceeding the limits of built artefacts, is a measure of the effect something has on the experience of space. Through the lens of the built environment, I expose the complex transactions that take place between networks, people and space. In order to evaluate architecturality of wireless communication signals, I conducted a series of practical design experiments, involving people and interactive installations, and using data gathered from mobile devices and wireless access points. The design of these experiments relies on the principles described by human-computer interaction (HCI) researchers as seamful design. Seamful design reveals underlying structures and relationships behind what appears as a utilitarian infrastructure. The design experiments contribute to the discussion on the use of design artefacts in practice-based research methodologies, thus challenging the different agents of knowledge production and the superiority of established research traditions. The insights gained from this complex examination of wireless networks are important for architectural design, as a way to account more adequately for signal propagation through buildings. The experience of internalising wireless networks in the process of design engenders a designerâs sensitivity towards the presence of wireless communications in space. This sensitivity, similar to the one we have for the distribution of natural and artificial lighting, will be needed in the ever more challenging design of the built environment. The sensible designer can account for, and envision, more dynamic environments that are able to accommodate change and information in completely new ways

Designing physical-digital artefacts for the public realm

The exploration of new types of everyday interactions enabled by the increasing integration of digital technologies with the physical world is a major research direction for interaction design research (Dourish, 2004), and a focus on materials and materiality is also of growing significance, e.g.: Internet of Things; interactive architecture; the intersection of craft and technology. Increasingly, designer-researchers from a range of material-focused creative design disciplines are starting to address these themes. Previous studies indicate that new approaches, methods and concepts are required to investigate the evolving field of physical-digital synthesis in the built environment. Addressing this, the thesis asks one central question: What resources for design research can help practitioners and researchers from multiple creative design disciplines improve the design of physical-digital artefacts located in the public realm? A detailed Scoping Study explored experimental research methods for this thesis and produced an overview of physical-digital artefacts in outdoor public space. This scoping influenced the subsequent research: an in-depth field study of the design culture and practices of fifty material-focused designer-researchers; four case studies of physical-digital artefacts in outdoor public spaces; a formative creative design workshop with fourteen participants to test the findings from the research. The chief contribution of this thesis to interaction design research is the development of two resources for design research (the Experiential Framework and the Conceptual Materials for Design Research) and the practical application of these new tools as a method for design research in a simulated ‘real-world’ creative workshop setting. Both resources are intended to co-exist and be integrated with established design research methods and emerging approaches. Hence, the outputs from this thesis are intended to support designer-researchers from a range of creative design backgrounds to conceptualise and design physical-digital artefacts for urban outdoor public spaces that provide richer interaction paradigms for future city dwellers
