This thesis presents two prescriptive models for approaching challenges to special operations forces with regard to personnel recovery in an urban environment. It begins by developing a model for overt recovery methods, using McRaven's model of Special Operations as the foundation. This model is then tested against three different case studies from operations in Mogadishu, Somalia in 1993. The original six principles proposed by McRaven are complimented with four newly-prescribed principles that account for the interactions of the isolated personnel. Following this analysis, a nonconventional assisted recovery model is presented for clandestine personnel recovery methods. This model borrows the relative superiority concept from McRaven's theory, but proposes six different principles. This model is evaluated using three case studies from the World War II era through Operation IRAQI FREEDOM. These cases support the idea that while the urban operational environment may vary across time and space, the principles supporting successful personnel recovery operations endure.

Abstract:
The need for a continuous supply of electric power is vital to providing the basic services of modern life. The energy infrastructure that the vast majority of the world depends on, while very reliable, is also very vulnerable. This infrastructure is particularly vulnerable to disruptions caused by natural disasters. Interruptions of electric service can bring an end to virtually all the basic services that people are dependent on. Recent natural disasters have highlighted the vulnerabilities of large, economically developed, regions to disruptions to their supply of electricity. The widespread devastation from the 2011 Japanese Tsunami and Hurricane Irene in North America, have demonstrated both the vulnerability of the contemporary power grids to long term interruption of service and also the potential of microgrids to ride through these interruptions. Microgrids can be used before, during, and after a major natural disaster to supply electricity, after the main grid source has been interrupted. This thesis researches the potential of clean energy microgrids for disaster recovery. Also a model of a proposed residential microgrid for transient analysis is developed. As the world demands more energy at increasingly higher levels of reliability, the role of microgrids is expected to grow aggressively to meet these new requirements. This thesis will look at one potential application for a microgrid in a residential community for the purpose of operating in an independent island mode operation.

Topal, Sebahattin. "Multi-robot Coordination Control Methodology For Search And Rescue Operations." Phd thesis, METU, 2011. http://etd.lib.metu.edu.tr/upload/12613841/index.pdf.

Full text
Abstract:
This dissertation presents a novel multi-robot coordination control algorithm for search and rescue (SAR) operations. Continuous and rapid coverage of the unstructured and complex disaster areas in search of possible buried survivors is a time critical operation where prior information about the environment is either not available or very limited. Human navigation of such areas is definitely dangerous due to the nature of the debris. Hence, exploration of unknown disaster environments with a team of robots is gaining importance day by day to increase the efficiency of SAR operations. Localization of possible survivors necessitates uninterrupted navigation of robotic aiding devices within the rubbles without getting trapped into dead ends. In this work, a novel goal oriented prioritized exploration and map merging methodologies are proposed to generate efficient multi-robot coordination control strategy. These two methodologies are merged to make the proposed methodology more realistic for real world applications. Prioritized exploration of an environment is the first important task of the efficient coordination control algorithm for multi-robots. A goal oriented and prioritized exploration approach based on a percolation model for victim search operation in unknown environments is presented in this work. The percolation model is used to describe the behavior of liquid in random media. In our approach robots start prioritized exploration beginning from regions of the highest likelihood of finding victims using percolation model inspired controller. A novel map merging algorithm is presented to increase the performance of the SAR operation in the sense of time and energy. The problem of merging partial occupancy grid environment maps which are extracted independently by individual robot units during search and rescue (SAR) operations is solved for complex disaster environments. Moreover, these maps are combined using intensity and area based features without knowing the initial position and orientation of the robots. The proposed approach handles the limitation of existing works in the literature such as
limited overlapped area between partial maps of robots is sufficient for good merging performance and unstructured partial environment maps can be merged efficiently. These abilities allow multi-robot teams to efficiently generate the occupancy grid map of catastrophe areas and localize buried victim in the debris efficiently.

Abstract:
Autonomous multi-agent systems perform inadequately in time critical missions, while they tend to explore exhaustively each location of the field in one phase with out selecting the pertinent strategy. This research aims to solve this problem by introducing a hierarchy of exploration strategies. Agents explore an unknown search terrain with complex topology in multiple predefined stages by performing pertinent strategies depending on their previous observations. Exploration inside unknown, cluttered, and confined environments is one of the main challenges for search and rescue robots inside collapsed buildings. In this regard we introduce our novel exploration algorithm for multi–agent system, that is able to perform a fast, fair, and thorough search as well as solving the multi–agent traffic congestion. Our simulations have been performed on different test environments in which the complexity of the search field has been defined by fractal dimension of Brownian movements. The exploration stages are depicted as defined arenas of National Institute of Standard and Technology (NIST). NIST introduced three scenarios of progressive difficulty: yellow, orange, and red. The main concentration of this research is on the red arena with the least structure and most challenging parts to robot nimbleness.

Abstract:
The temporary plug and abandonment (P&A) of old wells, and the following slot recovery, will be important for increasing the average rate of recovery from the Norwegian Continental Shelf (NCS). However, these operations faces challenges like high costs, safety concerns, environmental issues, and rapidly growing demand. Maintaining well integrity may be difficult when re-entering old wells. The demand for increased efficiency may lead operators to compromise on safety to finalize projects in time. This thesis tries to give a broad understanding of the well integrity issues on the NCS, and then tie these ndings around the term slot recovery operations. It will be important to understand the aspects which aects the lifetime of a well. Especially the long-term pressure, temperature and chemical effects on casings/tubings are important aspects to be understood. If this is done, one can increase the material lifetime in a well, and thus be able to re-use more of the casing strings in a slot recovery. These measures will help to keep marginal fields protable for a longer period. The thesis has also kept a strong focus on the challenges regarding the planning phase of a slot recovery operation. Of the essential factors in a slot recovery is to verify the old barrier envelope, and based on these findings create a robust operational plan. One of the mistakes which has been done in several slot recoveries is that the plan is created before any tests have been done. Once the plan is set and signed by the management, changes are harder to implement. Testing of the well often reveals unexpected factors which needs to be taken into consideration when planning an operation. Two separate slot recovery operations were also studied. They were carefully chosen to highlight typical issues with a slot recovery, and thus show that the theory fits with the reality. The requirements and guidelines for wells on the NCS also needs to be more customized for slot recovery operations.

Frequent interruptions are commonplace in modem work environments. The negative impacts of interruptions are well documented and include increased task completion and error rates in individual task activities, as well as interference with team coordination in team-based activities. The ramifications of an interruption in mission control operations, such as military command and control and emergency response, can be particularly costly due to the time and life-critical nature of these operations. The negative impacts of interruptions have motivated recent developments in software tools, called interruption recovery tools, which help mitigate the effects of interruptions in a variety of task environments. However, mission control operations introduce particular challenges for the design of these tools due to the dynamic and highly collaborative nature of these environments. To address this issue, this thesis investigates methods of reducing the negative consequences of interruptions in complex, mission control operations. In particular, this thesis focuses on supporting interruption recovery for team supervisors in these environments, as the research has shown that supervisors are particularly susceptible to frequent interruptions. Based on the results of a requirements analysis, which involved a cognitive task analysis of a representative mission control task scenario, a new interruption recovery tool, named the Interruption Recovery Assistance (IRA) tool, was developed. In particular, the IRA tool was designed to support a military mission commander overseeing a team of unmanned aerial vehicle (UAV) operators performing ground force protection operations. The IRA tool provides the mission commander a visual summary of mission changes, in the form of an event bookmark timeline. It also provides interactive capabilities to enable the commander to view additional information on the primary task displays when further detail about a particular mission event is needed. The thesis also presents the findings from a user study that was conducted to evaluate the effectiveness of the IRA tool on interruption recovery during collaborative UAV mission operations. The study produced mixed results regarding the effectiveness of the IRA tool. The statistical analysis indicated a negative impact on recovery time, while indicating a positive impact on decision accuracy, especially in complex task situations. The study also indicated that the effect of the IRA tool varied across differ user populations. In particular, the IRA tool tended to provide greater benefits to participants without military experience, compared to military participants involved in the study. The qualitative findings from the study provided key insights into the impact and utility of the IRA tool. These insights were used to identify several future research and design directions related to interruption recovery in mission control operations.

Abstract:
This thesis evaluates novel electronic physiologic monitor potential in remote and rural search and rescue. Casualties are often located a considerable distance away from definitive care. Their rescue involves a variety of groups, including volunteer rescue teams. Rescuers manage a wide range of medical problems, from minor issues to more serious, life-threatening conditions. However, casualty monitoring is restricted by steep terrain and extreme environmental conditions. Evidence indicated that novel electronic physiologic monitors were in development. Some were lightweight and wireless – it was hypothesised that such technology could facilitate health monitoring, conferring benefits to casualties and their carers. Novel physiologic monitor potential was explored using a multi-method approach, involving four methodologically distinct pieces of research. This included a reverseengineering approach to define the rescue context. A thematic review of remote and rural casualty rescues identified a potential worldwide demand for a novel monitor, although only a small proportion of casualties had severe injury. A longitudinal analysis of UK remote and rural casualties confirmed a consistent mountain rescue casualty demand for monitoring. Injury was more frequent than illness and a majority of injury involved suspected fracture to the lower extremity. A qualitative study identified evidence of support for novel monitors amongst rescuer groups. However, some felt that the environment and the variety of rescuer first-aid and medical training could negate monitor potential. A laboratory-function study evaluated the performance of an example of a novel monitor under simulated rescue conditions. There was little effect of several layers of clothing and a mountain rescue casualty bag on data accuracy. Taking all the evidence gathered into consideration, it was concluded that novel electronic physiologic monitors did have potential in remote and rural search and rescue. A concept design for a rescue-specific physiologic monitor was proposed, including software, hardware and architecture for future use.

Abstract:
The overall purpose of this thesis has been to increase the knowledge concerning leadership and stress in complex military and rescue operations. One of the biggest differences these leaders have to deal with compared to leaders in other kinds of organizations is the question of life and death. Their way of leading and handling stress may have consequences for their own lives, their subordinates' lives, and often also other people's lives. This thesis is based on four empirical studies which include multiple research methods, e.g. both qualitative and quantitative approaches. Paper I and II focus on indirect leadership in a military context and the main result are that indirect leadership can be understood as consisting of two simultaneous influencing processes. The first one is action-oriented and consists of interaction with a link which filters and passes the messages down to lower organizational levels. The second process is image-oriented and consists of being a role model. In the favourable case, trust is built up between the higher management and the employees. However, in the unfavourable case, there is a lack of trust, resulting in redefinitions of the higher managers' messages. Paper III and IV focused on leadership in complex and/or stressful rescue operations. In paper III, rescue operation commanders from complex operations were interviewed, and in paper IV, quantitative questionnaires were answered by informants from the ambulance services, the police force and the rescue services. The main result are that leadership in complex, stressful rescue operations can be understood as consisting of three broad timerelated parts: everyday working conditions, during an operation, and the outcome of an operation. The most important factors in explaining the outcome of a complex rescue operation were shown to be the organizational climate before an incident, positive stress reactions, and personal knowledge about one's co-actors during an operation.

Abstract:
With increasing presence and interest of shipping activities in the Arctic, the risk for an oil spill also increases. The activities are coupled to a growth of Arctic tourism (cruise vessels), exploitation of oil and gas resources as well as possibilities for merchant ships to sail the routes of Northwest and Northeast passages. The Arctic offers an impressive environment with high potential for tourism and offshore activities, however the Arctic is also highly vulnerable. Thus, higher demand of awareness of the risks as well as the possibilities and opportunities to take care of an oil spill and reduce the consequences are needed. Initially the report gives a background to the subject of Arctic oil spill which is followed by a review of Arctic oil spill response. The processes involved and oil spill countermeasures that are used or have shown potential in Arctic conditions are handled. To increase awareness a decision support tool which aims to cover preparedness, response and performance of an Arctic oil spill response operations is developted and presented. In the model structure, a wide range of input and sub-models are included to be able to cover the whole operation and different sub-areas that are identified. Finally a further developed part of the decision support tool is presented concerning the window of opportunity which review the response methods. The model, which is based on a Bayesian Network approach, provides the user with estimations of response method potentials as function of time. The model output are easy and clear to interpret for contingency planning as well as for operational use.

Auta, H. A. "Ultra scale-down process synthesis of microalgae primary recovery operations." Thesis, University College London (University of London), 2017. http://discovery.ucl.ac.uk/1553229/.

Full text
Abstract:
The majority of products made by microalgae and requiring extraction before use are restricted, commercially, by the high cost of the harvesting methods employed. Although considerable progress has been made in biofuel development there are still relatively few studies on the initial downstream processing stages. Ultra-scale down (USD) approaches have previously been established to study the impact of the engineering environment on biopharmaceuticals; they are valuable because they enable study of a wide range of operating parameters using minimal quantities of material and resources. The aim of this project is therefore to establish a USD platform for the rapid evaluation of pre-treatment and recovery operations for microalgae downstream processes. The first objective was to explore flocculation as a pre-treatment step. Flocculation is a difficult process to operate reproducibly, hence standardization of flocculation conditions becomes vital in order to characterize and quantify process performance. A series of scale-down flocculation reactors were designed, characterised and scaled-up using Chitosan to flocculate heterotrophically grown Chlorella sorokiniana. These enabled flocs with defined particle size distributions to be consistently and reproducibly produced. An optimal Chitosan concentration of 9.9 ± 0.4 mg.g-1 of algal dry cell weight was determined. Scale-up of the flocculation process from the scale-down reactor (120 mL) to a 7.5L STR stirred tank reactor was achieved at a fixed impeller tip speed during flocculant addition and ageing (0.29 and 0.07 ms-1 respectively). Due to the complex nature of unit operations, it is generally difficult to obtain data at laboratory scale that closely reflects the performance of operations at pilot scale or beyond. For the second objective of this work, a USD model of a cross-flow filtration process for microalgal biomass recovery was established. This could accurately reproduce the flux-TMP (transmembrane pressure) profiles of lab-scale hollow fibre cartridges when operated at a defined shear rate. The benefits of flocculation on filtration performance include a reduction in membrane cleaning cycles and a 20% reduction in filtration time. Filtration results were also in good agreement between the two scales for both unflocculated and flocculated feeds. The USD method enabled a 14-fold decrease in the volume of material required. It also demonstrated the benefits of flocculation. And lastly, USD was achieved using a 14.5–fold reduction in membrane area at matched volume: surface area ratio. The third objective was to establish a USD centrifugation method using a rotating disk shear device to expose particles to hydrodynamic shear before centrifugal separation. Evaluation of the influence of flocculation on centrifugation efficiency showed the benefits of increased particle size on clarification. Clarification efficiencies exceeding 99% was obtained even at low centrifugal forces using an optimal Chitosan dosage. The USD findings were validated at pilot scale using a CARR PowerfugeTM centrifuge. Similar clarification performance was predicted using 2000-fold less broth volume than was required for the pilot scale study. Sonication and homogenization as small scale cell disruption options for lipid release of heterotrophically grown C.sorokiniana were explored. Comparison of the optimal conditions of the two methods showed cell disruption and lipid release were similar in both cases on a g.g-1 basis. Finally comparison of the transesterified material produced using either USD microfiltration or USD centrifugation steps for harvesting showed major differences in terms of yield of fatty acid methyl esters (FAME). USD methods for evaluation of primary recovery operations and their interactions appear particularly useful in microalgae bioprocess synthesis. This work is the first to evaluate the use of USD technologies with microalgal cells. It illustrates the power of small-scale mimics to enable rapid selection and optimisation of different process options and thereby rational selection of the overall bioprocess sequence.

Abstract:
Disaster debris cleanup operations are commonly organized into two phases. During the first phase, the objective is to clear debris from evacuation and other important pathways to ensure access to the disaster-affected area. Practically, Phase 1 activities largely consist of pushing fallen trees, vehicles, and other debris blocking streets and highways to the curb. These activities begin immediately once the disaster has passed, with the goal of completion usually within 24 to 72 hours. In Phase 2 of debris removal, which is the focus of this study, completion can take months or years. Activities in this phase include organizing and managing curbside debris collection, reduction, recycling, and disposal operations (FEMA 2007). This dissertation research investigates methods for improving post-disaster debris cleanup operations—one of the most important and costly aspects of the least researched area of disaster operations management (Altay and Green 2006). The first objective is to identify the unique nature of the disaster debris cleanup problem and the important decisions faced by disaster debris coordinators. The second goal is to present three research projects that develop methods for assisting disaster management coordinators with debris cleanup operations. In the first project, which is the topic of Chapter 3, a facility location model is developed for addressing the problem of opening temporary disposal and storage reduction facilities, which are needed to ensure efficient and effective cleanup operations. In the second project, which is the topic of Chapter 4, a multiple objective mixed-integer linear programming model is developed to address the problem of assigning debris cleanup resources across the disaster-affected area at the onset of debris cleanup operations. The third project and the focus of Chapter 5 addresses the problem of equitably controlling ongoing cleanup operations in real-time. A self-balancing CUSUM statistical process control chart is developed to assist disaster management coordinators with equitably allocating cleanup resources as information becomes available in real-time. All of the models in this dissertation are evaluated using data from debris cleanup operations in Chesapeake, Virginia, completed after Hurricane Isabel in 2003.

In the Organisation for Economic Co-operation and Development (OECD) area, the production of numerical solid waste (MI\SW) increased by 32% between 1990 and 2011, exceeding 660 million tonnes in 2011; the world-wide production of waste is estimated to grow further due to increasing GDP in developing economies. Given this scenario, effective treatment and recovery of wastes becomes a priority. In developed countries, MSW is usually sent to materials recovery facilities (MRFs), which use mechanical and manual sorting units to extract valuable components. In this work, we define a network flow model to represent a MRF that sorts wastes using multi-output units with recirculating streams. For each material in the system, we define a matrix to describe the sorting process. We then formulate a genetic algorithm (GA) that generates alternative configurations of a MRF having a given set of sorting units with known separation parameters and selects those with highest profit and efficiency. The GA incorporates a heuristic for personnel allocation to manual units. We code the algorithm in Java and apply it to an existing MRF. The results show a 33.4% improvement in profit and a 1.7% improvement in efficiency with respect to the current configuration without hand sorting; and a 6.7% improvement in profit and a 3.9% improvement il efficiency, with respect to the current configuration with hand sorting.

Abstract:

I takt med att Försvarsmakten ökar sitt internationella engagemang ökar också riskerna för att svensk personal ska bli isolerad, tillfångatagen eller kidnappad. Syftet med den här uppsatsen är att undersöka om svensk undsättningsförmåga är tillräcklig för de insatser som Försvarsmakten genomför internationellt.

Det kan konstateras att flera faktorer bidrar till ett behov av en undsättningsförmåga. Försvarsmakten har en moralisk skyldighet mot sin personal att göra allt för att se till att de kommer hem ifall något skulle hända dem. Försvarsmakten har heller inte råd att få personal kidnappad då det genom media och hemmaopinion kan ge ett högt tryck på politiker vilket i sin tur kan leda till att Försvarsmakten tvingas dra sig ur en insats. Förvarsmakten måste även kunna ansvara för sig själv och inte förlita sig på att en annan nation ska lösa problemet när situationen inte kan hanteras. I övriga europeiska länder saknas i många fall en fullgod undsättningsförmåga och därför blir det än viktigare att Försvarsmakten innehar en egen förmåga. Förmågan bör åtminstone omfatta kvalificerade helikoptrar och välutbildade undsättningsenheter med rätt utrustning för att en trovärdig undsättningsförmåga ska finnas i organisationen.

Resultaten av uppsatsen tyder på att Försvarsmakten har kommit långt i sin strävan att utveckla en undsättningsförmåga men att organisationen brister i att utveckla verkligt kvalificerade undsättningsförband. Dessa förband bör tilldelas mer resurser för att en trovärdig förmåga kopplat mot Försvarsmaktens målsättning ska upprätthållas.


When the Swedish Armed Forces are increasing its contribution to international peacekeeping missions there is an increasing danger that Swedish personnel could find themselves isolated and taken hostage. The purpose with this work is to examine whether the level of Swedish Personnel Recovery is acceptable due to the international missions the Swedish Armed Forces is participating in. 

The Swedish Armed Forces has the moral responsibility to bring all personnel home when deployed. One reason to have Personnel Recovery capability is to reduce the danger of getting personnel executed and media exploiting it which could lead to a withdrawal from the area. Further on Swedish Armed Forces have got to have its own Personnel Recovery capability since not very many countries has a sufficient capability. The Swedish Armed Forces Personnel Recovery capability should at least contain qualified helicopters and Personnel Recovery units.

The results of this work is that the Swedish Armed Forces has made huge progress in developing a Personnel Recovery capability although there is a lack of truly qualified Personnel Recovery units which should be given sufficient funds to enhance the Swedish Personnel Recovery capability.

Abstract:
Cette thèse étudie le design et la conception d’un Goniomètre Radio Fréquence (GRF) visant à assister les services de secours à la personne (e.g. équipes de sauvetage déblaiement), exploitant les téléphones des victimes à retrouver comme des balises de détresse radio. La conception est focalisée sur une interface audio, utilisant le son pour guider progressivement les sauveteurs vers la victime. L’ambition de la thèse est d’exploiter les mécanismes naturels propres à l’audition humaine pour améliorer les performances générales du processus de recherche plutôt que de développer de nouvelles techniques d’Estimation de Direction de Source (EDS).Les techniques d’EDS classiques sont tout d’abord exposées, ainsi qu’une série d’outils permettant d’en évaluer les performances. Basée sur ces outils, une étude de cas est proposée visant à évaluer les performances attendues d’un GRF portable, adapté aux conditions d’emploi nominales envisagées. Il est montré que les performances des techniques dites « à haute résolution » généralement utilisées pour l’EDS sont sérieusement amoindries lorsqu’une contrainte de taille/poids maximum est imposée sur le réseau d’antennes associé au GRF, particulièrement en présence de multi-trajets de propagation entre le téléphone ciblé et le tableau d’antenne.Par la suite, une étude bibliographique concernant la sonification par encodage de paramètres (Parameter Mapping Sonification) est proposée. Plusieurs paradigmes de sonification sont considérés et évalués en rapport à leur capacité à transmettre une information issue de différents designs de GRF envisagés. Des tests d’écoute sont menés, suggérant qu’après une courte phase d’entrainement les sujets sont capables d’analyser plusieurs flux audio en parallèle ainsi que d’interpréter des informations de haut niveau encodées dans des flux sonores complexes. Lesdits tests ont permis de souligner le besoin d’une sonification du GRF basée sur une hiérarchie perceptive de l’information présentée, permettant aux débutants de focaliser leur attention sans efforts et uniquement sur les données les plus importantes. Une attention particulière est portée à l’ergonomie de l’interface sonore et à son impact sur l’acceptation et la confiance de l’opérateur vis-à-vis du GRF (e.g. en ce qui concerne la perception du bruit de mesure pendant l’utilisation du GRF pendant la navigation).Finalement, un prototype virtuel est proposé, simulant une navigation basée sur le GRF dans un environnement virtuel pour en évaluer les performances (e.g. paradigmes de sonification proposés plus haut). En parallèle, un prototype physique est assemblé afin d’évaluer la validité écologique du prototype virtuel. Le prototype physique est basé sur une architecture radio logicielle, permettant d’accélérer les phases de développement entre les différentes versions du design de GRF étudiées. L’ensemble des études engageant les prototypes virtuels et physiques sont menées en collaboration avec des professionnels des opérations de recherche à la personne. Les performances des designs de GRF proposés sont par la suite comparées à celles des solutions de recherche existantes (géo-stéréophone, équipes cynotechniques, etc.).Il est montré que, dans le contexte envisagé, un simple GRF basé sur la sonification en parallèle des signaux provenant de plusieurs antennes directionnelles peut offrir des performances de navigations comparables à celles résultantes de designs plus complexes basés sur des méthodes à haute résolution. Puisque l’objectif de la tâche est de progressivement localiser une cible, la pierre angulaire du système semble être la robustesse et la consistance de ses estimations plutôt que sa précision ponctuelle. Impliquer l’utilisateur dans le processus d’estimation permet d’éviter des situations critiques où ledit utilisateur se sentirait impuissant face à un système autonome (boîte noire) produisant des informations qui lui semblent incohérentes
This research investigates the design of a radio Direction Finder (DF) for rescue operation using victims' cellphone as localization beacons. The conception is focused on an audio interface, using sound to progressively guide rescuers towards their target. The thesis' ambition is to exploit the natural mechanisms of human hearing to improve the global performance of the search process rather than to develop new Direction-Of-Arrival (DOA) estimation techniques.Classical DOA estimation techniques are introduced along with a range of tools to assess their efficiency. Based on these tools, a case study is proposed regarding the performance that might be expected from a lightweight DF design tailored to portable operation. It is shown that the performance of high-resolution techniques usually implemented for DOA estimation are seriously impacted by any size-constraint applied on the DF, particularly in multi-path propagation conditions.Subsequently, a review of interactive parameter mapping sonification is proposed. Various sonification paradigms are designed and assessed regarding their capacity to convey information related to different levels of DF outputs. Listening tests are conducted suggesting that trained subjects are capable of monitoring multiple audio streams and gather information from complex sounds. Said tests also indicate the need for a DF sonification that perceptively orders the presented information, for beginners to be able to effortlessly focus on the most important data only. Careful attention is given to sound aesthetic and how it impacts operators' acceptance and trust in the DF, particularly regarding the perception of measurement noise during the navigation.Finally, a virtual prototype is implemented that recreates DF-based navigation in a virtual environment to evaluate the proposed sonification mappings. In the meantime, a physical prototype is developed to assess the ecological validity of the virtual evaluations. Said prototype exploits a software defined radio architecture for rapid iteration through design implementations. The overall performance evaluation study is conducted in consultation with rescue services representatives and compared with their current search solutions.It is shown that, in this context, simple DF designs based on the parallel sonification of the output signal of several antennas may produce navigation performance comparable to these of more complex designs based on high-resolution methods. As the task objective is to progressively localize a target, the system's cornerstone appears to be the robustness and consistency of its estimations rather than its punctual accuracy. Involving operators in the estimation allows avoiding critical situations where one feels helpless when faced with an autonomous system producing non-sensical estimations. Virtual prototyping proved to be a sensible and efficient method to support this study, allowing for fast iterations through sonifications and DF designs implementations

Efficient integrated/robust planning and recovery models were studied. The research focus was to integrate fleet assignment and crew scheduling, and, in addition, to provide solutions robust to real time operations. The contributions include: (1) To understand how schedule development and fleet assignment stages influence crew scheduling performance, schedule analysis methods were proposed to evaluate the crew friendliness of a schedule for a given fleet. (2) To meet the computational challenges of crew scheduling in integrated planning, a duty flow model was proposed which can efficiently find suboptimal legal pairing solutions. (3) A new robust crew scheduling method based on spoke purity was proposed. Computational results indicated that with little or no extra cost, a more robust crew pairing solutions can be expected. (4) By imposing station purity, an integrated and robust planning model which integrates fleet assignment and crew connections was proposed. The impact of crew base purities and fleet purities on FAM profit, crew scheduling, and computational efficiency were investigated. (5) Airline integrated recovery method was studied. A recovery scope for integrated recovery was proposed to limit the ripple effect caused by disruptions. Based on the defined recovery scope, a new integrated recovery model and Bender¡¯s decomposition solution approach was studied.

ENGLISH ABSTRACT: Search and Rescue is an essential service provided by States and Militaries to search for, locate and rescue survivors of accidents and incidents. Civil Search and Rescue utilizes a system of well-trained professionals or volunteers, an effective Search and Rescue organization, supported by industry and other providers of infrastructure and assets. The service is rendered to save the lives of civilian individuals in imminent danger of losing their lives. Military (Combat) Search and Rescue is provided by militaries to save the lives of military practitioners in a similar predicament. In addition, Search and Rescue is performed over land and over the sea. All forms of Search and Rescue rely on capable, specialized assets for efficiency en affectivity. Assets are specified and chosen on the grounds of various factors, amongst others operating environment, operational profile, performance and special abilities. This thesis has determined the need for a Search and Rescue asset, capable of performing effective and efficient Search and Rescue over the entire national maritime Search and Rescue Region, up to the Region extremities. An analysis was performed to prove this deficit, and quantify the key performance and special equipment requirements for such an asset. An analysis was also performed which proves that an Unmanned Aircraft System should be an ideal choice to meet this need. Finally, an Unmanned Aircraft System concept was specified that could potentially meet this need.
AFRIKAANSE OPSOMMING: Soek en Redding is ‘n essentiële diens wat deur State en militêre organisasies gebied word om oorlewendes van ongelukke en insidente te soek, op te spoor en na veiligheid te bring. Siviele Soek en Redding maak gebruik van ‘n stelsel van goedopgeleide professionele persone, sowel as vrywilligers, asook ‘n effektiewe Soek en Reddingsorganisasie, ondersteun deur die industrie en ander voorsieners van infrastruktuur en toerusting. Derglike dienste word daargestel om die lewens van siviele persone, wie se lewens in gevaar is, te red. Militêre Soek en Redding word deur militêre organisasies daargetel om die lewens van militêre persone, wie in gevaar is, te red. Soek en Redding word oor land sowel as oor die see uitgevoer. Alle vorms van Soek en Redding maak staat op die beskikbaarheid van gespesialiseerde toerusting met gespesialiseerde gebruiksaanwending, vir maksimale effektiwiteit en doeltreffendheid. Toerusting word gekies op grond van verskeie faktore, onder meer die gebruiksomgewing, operasionele profiele, verlangde prestasie en spesiale vermoëns. Hierdie tesis het die behoefte aan ‘n gespesialiseerde Soek en Redding platform, wat die vermoë het om effektiewe en doeltreffende Soek en Redding uit te voer oor die hele nationale Soek en Redding Gebied, tot en met die ekstreme daarvan, vasgestel. ‘n Analise is uitgevoer om hierdie tekortkoming uit te wys, asook om die sleutel prestasie- en gespesialiseerde toerustingbehoeftes vir so ‘n platform te kwantifiseer. ‘n Verdere analise is uitgevoer om te bewys dat ‘n Onbemande Vliegtuig die beste opsie sou wees vir ‘n platform om aan hierdie behoeftes te voldoen. Ten slotte is ‘n konsep vir ‘n Onbemande Vliegtuig Stelsel voorgetsel wat potensieël hierdie behoefte sou kon vervul.

Since the events of 9/11 and Hurricane Katrina, emergency management has put great efforts into formalizing response and recovery structures following natural and man-made disasters. However, these formalized structures are not often flexible enough to allow for the innovation that each different disaster may require to best meet the needs of the impacted citizens in the most effective and efficient way possible. As emergency management continues to become more complex, organizational leadership will be challenged to balance the need for standard operating procedures and policies against the ability to leverage emergent behavior that allows for innovation in addressing the specific problems brought on by each unique disaster. This thesis focuses on identifying under what circumstances emergent behavior is desired within the context of emergency management, and how organizational leadership can impact the factors that enhance or inhibit emergence during response and recovery operations. Using participant observation methods over the course of many years of disaster leadership, eight different incidents were analyzed for the identification of leadership themes that impacted emergent behavior. As a result of these findings, five themes emerged in which emergency management's organizational leadership can most effectively impact self-organizing behavior within its ranks. With an understanding of when emergence is desirable, and by developing the capacity and an organizational culture that supports the vacillation between structure and innovation, emergency management officials will be better able to lead effective responses to complex incidents.

Abstract:
There has been great interest in the use of small robotic helicopter vehicles over the last few years. Although there are regulatory issues involved in flying these that are still to be solved, they have the potential to provide a practical mobile aerial platform for a small fraction of the cost of a conventional manned helicopter. One potential class of applications for these is in searching for people, and this thesis explores a new generation of cameras which are suitable for this purpose. We propose HeatTrack, a novel algorithm to detect and track people in aerial imagery taken from a combined infrared/visible camera rig. A Local Binary Patterns (LBP) detector finds silhouettes in the infrared image which are used guide the search in the visible light image, and a Kalman filter combines information from both modalities in order to track a person more accurately than if only a single modality were available. We introduce a method for matching the thermal signature of a person to their corresponding patch in the visible modality, and show that this is more accurate than traditional homography-based matching. Furthermore, we propose a method for cancelling out camera motion which allows us to estimate a velocity for the person, and this helps in determining the location of a person in subsequent frames. HeatTrack demonstrates several advantages over tracking in the visible domain only, particularly in cases where the person shows up clearly in infrared. By narrowing down the search to the warmer parts of a scene, the detection of a person is faster than if the whole image were searched. The use of two imaging modalities instead of one makes the system more robust to occlusion; this, in combination with estimation of the velocity of a person, enables tracking even when information is lacking in either modality. To the best of our knowledge, this is the first published algorithm for tracking people in aerial imagery using a combined infrared/visible camera setup.

Abstract:
This paper aims to answer the question of how artificial intelligence could help humans maintain and/or improve situational awareness in search and rescue operations at sea, as well as where in such processes artificial intelligence could be incorporated to most efficiently compensate for human vulnerabilities and support human strengths. In order to answer this, a joint cognitive system perspective has been adopted whilst joining in search and rescue practice operations. These operations have been observed and persons participating in them have been interviewed, in order to gather insights about the process and the persons conducting it. The results from these insights coupled with experience with artificial intelligence and automation, show that artificial intelligence could help improve and/or maintain situational awareness by adopting functions which take up unnecessary time from man. According to the joint cognitive system view, these functions should never be solely performed by artificial intelligence however, but in coagency with man; allocated functions should overlap between man and machine. Suggestions have been given regarding which functions in particular an artificial intelligent agent could perform in terms of search and rescue and where these functions occur in the process. None of these suggestions are without man involvement, as they should not be. To summarise, these suggestions include; a UAV equipped with an infrared camera to search large areas quickly, a decision support system equipped with image recognition to analyse images gathered from the UAV, as well as a communication tool which allows for shared search patterns and hotspots between search and rescue units.

Abstract:
This study uses scanning electron microscopy (SEM) to examine the occurrence of bacteria and their exopolysaccharide slime layer in microbial enhanced oil recovery experiments. A test of SEM preservation techniques showed that air drying and 10% glutaraldehyde fixation preserved the slime layer but distorted and flattened bacteria. Techniques with ethanol dehydration preserved the bacterial textures but fragmented the slime layer. In sandstones that had been plugged during microbial enhanced oil recovery experiments, bacteria are sparsely distributed. An irregular, confluent slime sheet covers grains and coats pore spaces and is responsible for permeability modification in microbial enhanced oil recovery. The development of the slime layer over time involves several steps: growth of ultramicrobacteria into full-sized bacteria; creation of a slime capsule; growth of globular masses, ropy masses, webs, thin sheets; and growth of a thicker, pore-filling mass of slime associated with large balls of slime.

The recent movement in healthcare reform requires hospitals to care for more patients while simultaneously reducing costs. Medical institutions can no longer afford to simply add beds and hire staff to increase capacity. They must use existing resources more effectively and develop innovative solutions to increase capacity. This project focuses on the redesign of surgical patient flow through multiple Post-Anesthesia Care Units (PACUs) at Massachusetts General Hospital (MGH). The PACU is where surgical patients recover following their procedure that takes place in the Operating Room (OR) suite. Some patients experience delays when leaving the OR due to the lack of a staffed PACU bed. These patients begin the recovery process in the OR which causes delays for to-follow cases. In addition, the OR nursing staff rather than a PACU nurse must monitor recovery, which drives higher costs and frustrates staff members. Therefore this study examined the sources of delay and sought to redesign the flow of surgical patients through the PACUs. Our main recommendation is to incorporate a "Fast Track" for the outpatient population that eliminates delays and expedites outpatient processing in the PACU. Segregating the outpatients and implementing the one-stop "Fast Track" recovery process will reduce average outpatient PACU length of stay (length of stay) by 27%, the equivalent of adding 1.8 beds of capacity. Through the application of operations management techniques, we can decrease the patient processing time or length of stay in the PACU, which in turn increases throughput and creates additional capacity.
