This thesis focuses on the potential tactical uses of Quick Response (QR) codes for optical signaling. It examines visual communications methods used effectively by the fleet throughout history, both during peacetime and wartime operations. Due to the advent of new technology, radio frequency line- of-sight (RF LOS) communications have come to the forefront of current operations, leaving the fleet vulnerable when conducting operations in an emissions-controlled (EMCON) environment. The need for a reliable visual line- of-sight (LOS) communications method has become apparent. The use of QR codes also can circumvent the problems associated with Hazards of Electromagnetic Radiation to Ordinance (HERO) as well as provide an effective means of conducting Identification Friend Foe/Neutral (IFFN). QR codes have the ability to become the newest and most effective method of visual communication for the Navy. The thesis also examines the use of various sensors and cameras to read and decode QR codes, and proposes specific uses of QR codes for communications on board ships, aircraft, and UAVs. Prototype software is provided as an initial-candidate QR Tactical Decision Aid (TDA). The ultimate goal of the thesis is to provide the fleet with an option for a visual communications method that allows ships and other units operating in a tactical emissions- controlled environment to minimize communications vulnerability and maximize operational effectiveness.

Today's nuclear power plant (NPP) instrumentation uses current loops and voltage-based communications sometimes compromised by radio frequency interference (RFI), also called electromagnetic interference (EMI). Copper-based communications technology also relies on insulation that may degrade after decades of exposure to NPP environments and can be flammable. Wireless technologies offer the potential for greater expansion in instrumentation in a plant that could augment human performance, provide additional data on plant equipment and component status, and facilitate online assessment of the material condition of plants. Wireless communications capabilities may substantially reduce the cabling cost, but a number of technology and security issues must be resolved. One of the greatest capital cost contribution from I&C systems arises from cable installation. The trend toward more effective, efficient operation and maintenance will require many additional sensors beyond the number of nuclear and process sensors at a conventional NPP. These additional sensors are needed to enable monitoring of real-time process variables, structural components, movable equipment, portable devices, and warehouse/inventory areas, but will exacerbate the cabling complexity and cost. Wireless technologies offer the potential for greater expansion in instrumentation in a plant that could augment human performance, provide additional data on plant equipment and component status, and facilitate online assessment of the material condition of plants.

Since publishing the Great Lakes Networks first communication plan, science communication, particularly in the National Park Services Inventory and Monitoring program, has taken root and become an integral part of our work. Our first communication plan was necessarily broad in its goals and objectives because we were learning what was needed by parks and how we would fulfill those needs. We have been relatively successful in our efforts. In a 2011 survey of staff at the nine Network parks, 78of respondents said they were aware of Network monitoring programs being carried out in their parks. Thus, the goals and objectives in this plan are not much different than they were in 2009, but by achieving the four goals we have set in this version, we should improve upon the flow of information and diversify how it is presented. We are striving to clarify the relevance of our data to park management, strengthen the relationships between the Network and park interpreters, and to begin using social media and webinar technology. As always, we will evaluate our work towards these goals and continue improving how we work with and assist the Great Lakes Network parks.

U.S. Army leaders acknowledge the importance of the Human Domain, and it is therefore in the Army's best interest to retain the capabilities and knowledge built over the past 12 years. Failure to maintain these capabilities will inevitably mean redeveloping them during the next conflict at the cost of national treasure, e.g. American lives and dollars. Historically, the Army's improvements in process and technique draw directly from lessons learned in conflict. However, there is value in looking at empirical research drawn from fields with relevant parallels to practices used by influence operators. Within academia, there exists a vast amount of research on techniques and procedures influence operators can utilize. This study sought to identify how Army influence operators can benefit from outside institutions, and not rely solely on our experiences to further our capabilities. Therefore, this paper looked at what mass communication, advertising, and marketing research influence operators can adapt and implement at the strategic and operational levels of war. As a result, this study identified four reinforcing takeaways from the academic literature and two distinct recommendations for implementation, an additional step in the doctrinal process and training for our influence operators in communication strategy design that better supports the military campaign.

Miniature microscopes are being developed to examine tissue in situ for early anatomic and molecular indicators of disease, in real time, and at cellular resolution. These new devices will lead to a shift from the current diagnostic paradigm of biopsy followed by histopathology and recommended therapy, to one of non-invasive point-of-care diagnosis with the possibility of treatment in the same session. This potential revolution in disease management may have a major impact on the training of future physicians to include the use and interpretation of real-time in vivo microscopic data, and will also affect the emerging fields of telepathology and telemedicine. Implementation of new technologies into clinical practice is a complex process that requires multidisciplinary communication and collaboration among clinicians, engineers and scientists. As such, our aim is to provide a forward-looking view of the critical issues facing the development of new technologies and directing clinical education. Here, we focus on the use of in vivo microscopy for detection of malignant and pre-malignant lesions as well as for guiding therapy. We will highlight some of the areas in which in vivo microscopy could address unmet clinical needs, and then review the technological challenges that are being addressed, or need to be addressed, for in vivo microscopy to become an effective clinical tool.

Advancing technologies in smallsats provide remote sensing and communications capabilities achievable with a constellation of satellites at a reasonable cost to meet military needs. Like any other nation looking for a cheap but effective solution in that area, Turkey might also benefit from a replacement of its remote sensing assets. Currently, Turkish Armed Forces rely on a limited number of reconnaissance aircraft and Unmanned Aerial Vehicles, which do not provide real-time or near real-time remote sensing capabilities. Near real-time remote sensing needs for the Turkish warfighter dictates that the Turkish Armed Forces reach that capability as soon as possible. Likewise, replacing its conventional communication radios with satellite communication devices would also fulfill its warfighter needs. While current communication devices have physical limitations in Turkey's mountainous terrain and the surrounding seas, satellite communication capability would provide a wider coverage, and for specific frequencies, it might provide better resistance to jamming and interference. For the benefit of the Turkish Armed Forces' communications needs, a satellite constellation must be optimized such that effective coverage will be achieved with the least number of satellites to provide a reasonable cost. In this study, satellite constellation optimization for the Turkish Armed Forces will be achieved using Analytical Graphics, Inc.'s Systems Tool Kit software for simulation and analysis of several possible communications and remote sensing satellite constellations covering Turkish territory and surrounding seas. The Concept of Operations (CONOPS) for a smallsat constellation will be described and an optimized smallsat constellation will be modeled using STK software. The resulting data will be analyzed and discussed in the form of a recommendation that would benefit the Turkish Armed Forces.

NASA has developed an experimental flight payload (referred to as the Space Communication and Navigation (SCAN) Test Bed) to investigate software defined radio (SDR) communications, networking, and navigation technologies, operationally in the space environment. The payload consists of three software defined radios each compliant to NASAs Space Telecommunications Radio System Architecture, a common software interface description standard for software defined radios. The software defined radios are new technology developments underway by NASA and industry partners launched in 2012. The payload is externally mounted to the International Space Station truss to conduct experiments representative of future mission capability. Experiment operations include in-flight reconfiguration of the SDR waveform functions and payload networking software. The flight system will communicate with NASAs orbiting satellite relay network, the Tracking and Data Relay Satellite System at both S-band and Ka-band and to any Earth-based compatible S-band ground station. The system is available for experiments by industry, academia, and other government agencies to participate in the SDR technology assessments and standards advancements.
