Circasemiannual chronomics: half-yearly biospheric changes in their own right and as circannual waveform
No full textGeomagnetic activity has a strong half-yearly but no precise yearly component in its spectrum, as Armin Grafe suggested nearly half a century ago. We have postulated elsewhere that non-photic cycles such as those in geomagnetics may have signatures in the biosphere and vice versa that biological rhythms have likely counterparts in the physical environment. Accordingly, we document phenomena characterized by a prominent about half-yearly variation, re-analyzed to constitute the start of a transdisciplinary chronomic (time structural) map, aligning these conditions with a half-yearly cycle in the geomagnetic index Kp. At least some biospheric phenomena fitted concomitantly with 1– and 0.5–year cosine curves exhibit an amplitude (A) ratio of A0.5–year/A1–year larger than unity. Methodologically, it is pertinent that even if data were read off published graphs, the resulting analyses were practically the same as those in the original data received subsequently. The main point is a circasemiannual pattern in status epilepticus, in several morbid oral conditions, in the cell density of vasopressin-containing neurons in the human suprachiasmatic nuclei (SCN), in circulating melatonin at middle latitudes at night during years of minimal solar activity or around noon at high latitudes, and in an unusual circasemiannual aspect of a birth-month-dependence of human longevity. Others have asked whether annual rhythms in human reproduction are biological, sociological or both. We show some other possibilities herein, involving the physical environment, hardly to be neglected in the case of open systems. As to almost certainly multifactorial circasemiannual rhythms, geomagnetics may also be a signal, a proxy or a putative, at least partial mechanism. Geomagnetic activity is related in its turn to solar and galactic activity, and may be a marker for other cyclic events that affect the biosphere. The similarity of cycle lengths in itself can only be a hint prompting the search for causal relations

A Writer’s Board and a Student-Run Writing Clinic: Making the Writing Community Visible at Law Schools
No full textIn this article the author explains institutional programs she has developed in response to a common problem, students’ frustrations with the limits of a law school’s legal writing program. The author proposes establishing a Writers’ Board, where members of the law school community who care most about legal research and writing training can work together to create opportunities for students to learn more. The Writers’ Board’s primary project is a Writing Clinic that offers diverse ways to improve legal research and writing on campus. Despite problems that are likely to arise when creating a Writers’ Board and Clinic, the author concludes that these projects will not only improve legal research and writing training, but also raise students’ confidence in the writing program and in themselves, and draw positive attention to a law school’s legal writing program
DEFENSE INSTALLATION ENERGY RESILIENCE FOR CHANGING OPERATIONAL REQUIREMENTS
No full textA process is proposed to determine the impact of different potential mission scenarios upon energy resilience for mission-critical loads attached to a military base’s microgrid infrastructure. This process applies to any institution with changing operational states whose energy resilience requirements necessitates redundant electrical supply. The methodology may be used by energy managers to account for potential mission scenarios that a base may be part of, followed by assessing the microgrid energy resilience to supply the critical loads for said mission scenarios, especially where external grid power may be unavailable and/or damage to facility microgrid systems may be present. In the event a microgrid design is unable to provide sufficient electrical energy, distributed energy resources (DERs), including energy storage systems and renewable energy resources, may be added to improve energy resilience. A case study is conducted with a fictitious military base, microgrid design, and changing operational demands to demonstrate the application of the methodology. This paper contributes a method for energy managers to evaluate energy resilience using microgrids by accounting for potential mission operations, their energy requirements, resulting energy preparedness, and recommendations for improvement as necessary.Approved for public release.

MODELLING THE PERFORMANCE OF AND ANALYZING THERMAL RADIANCE REDUCTION BY A WATER-COOLED THERMOELECTRIC WASTE HEAT HARVESTING SYSTEM AND THE DEVELOPMENT OF AN AIR-COOLED HEAT SINK REPLACEMENT
No full textPropulsion and electrical generator systems that utilize fossil fuels experience losses in efficiencies due to waste heat. While there are a number of ways to recover some of this waste heat, this research focuses on a waste heat harvesting system that uses thermoelectric generators (TEGs). TEGs operate via the Seebeck effect, where a temperature difference generates an electric potential. This project consists of three parts. The first part details the steps taken to model the existing water-cooled thermoelectric waste heat harvesting prototype using COMSOL Multiphysics Finite Element Analysis Software. The second part analyzes how well the water-cooled prototype reduces the thermal signature of the gasoline-powered generator’s muffler. This application shows that it could be useful in minimizing asset visibility in the infrared spectrum for expeditionary missions. The last part discusses the design, fabrication, and performance of a passive, air-cooled variant of the thermoelectric waste heat harvesting system. When water-cooled applications are not feasible, as with expeditionary vehicles, having an air-cooled version is possible.Approved for public release. distribution is unlimitedLieutenant, United States Nav
ASSESSMENT OF EXTERNAL RELIABILITY DATA SOURCES AND RELIABILITY PREDICTIONS OF COMPLEX SYSTEMS IN EARLY SYSTEM DESIGN
No full textTwo common reliability prediction methods are the traditional method and physics of failure method. Each method requires accurate failure data in order to fully assess a system’s durability. This is particularly important in early system design when historical design and relative failure rates are non-existent. Consequently, practitioners rely on the use of external reliability data sources such as MIL-HDBK-217F, especially when using the traditional reliability approach. Several other external reliability data sources are available to the practitioner, each with its own strengths and limitations. This thesis surveys the various external data sources industries use in reliability predictions and assesses the completeness of the reliability data sources. The thesis presents the inherent limitations of all external data sources along with further considerations on using the traditional reliability approach. Early system design offers practitioners a significant amount of decision-making flexibility. This thesis further analyzes both reliability approaches and addresses when it is appropriate for a practitioner to use either approach or a combination of the two approaches. The author develops a reliability decision framework to aid practitioners in selecting the reliability prediction approach appropriate for the system.Approved for public release; distribution is unlimited.Civilian, Department of the Navyhttp://archive.org/details/assessmentofexte109456042
Diagnosis and Analysis of Marine Corps Organizational Culture
No full textThis report presents the results of a study into Marine Corps organizational
culture. This report is being submitted to the Naval Postgraduate School’s Senior Marine in partial fulfillment of the requirements of an Executive Masters in Business Administration program. Organizational culture consists of all of the taken for granted values and underlying assumptions that characterize an organization and its members (Robbins & Judge, 2012). It is the tie that binds an organization together (Cameron & Quinn, 2011). Organizational performance is often linked to organizational culture (Robbin & Judge, 2012), and can change in response to internal or external stimuli (Cameron & Quinn, 2011). The Organizational Culture Assessment Instrument (OCAI) is based on the Competing Values Framework, which characterizes culture as a competition between flexibility and discretion versus stability and control on one hand, and internal focus and integration versus external focus and differentiation on the other. This struggle results in four common cultures: clan, adhocracy, market, and hierarchy. (Cameron & Quinn, 2011) The Organizational Culture Assessment Instrument was administered to Marine Officers (students) at the Naval Postgraduate School by the Senior Marine Staff in December of 2014. In all, 173 questionnaires were completed. Data from these questionnaires were put in a spreadsheet and forwarded to the author for subsequent analysis. Analysis found that Marine Corps organizational culture is currently 21.2 percent clan, 13.4 percent adhocracy, 35.4 percent market, and 29.9 percent hierarchy. The current organizational culture is weighted toward stability and control, as well as toward viii external focus and differentiation. The data reveals a desire to move toward flexibility and discretion, and external focus and differentiation. Specifically, the data reveals the desire to move from hierarchy and toward adhocracy culture in terms of the Dominant Characteristic, Management of Employees, and Organizational Glue dimensions. The data also reveals a desire to move from market and toward clan culture in the Organizational Leadership dimension. No distinguishable Company and Field Grade sub-cultures are noted, suggesting that current Marine Corps organizational culture is vertically homogeneous (characteristic of high-functioning organizations). Current Marine Corps organizational culture contains marginally distinguishable Service Group or community sub-cultures. Air Officers find the current organizational culture more market-like, while Ground Officers find the current organizational culture more clan-like. Service Support Officers are essentially a hybrid of the Air and Ground sub-cultures. The value of cultural change is illustrated with a story about the New United Motors Manufacturing Incorporated (NUMMI) plant in Fremont, California. The value of initiating organizational culture change in the Marine Corps is briefly discussed, as well as the idea that individual change is the key to organizational change via a known six step process. Finally, recommendations are made, to include recommendations for future work. The principle recommendation is to initiate internal discussion and raise awareness of the value of organizational culture, and the need to manage it, by publishing the current and preferred Marine Corps organizational culture profiles in a visible venue like the Marine Corps Gazette.Approved for public release; distribution is unlimited.http://archive.org/details/diagnosisndanaly109456327
EXPERIMENTAL VALIDATION OF RESILIENCE MODELS FOR ISLANDED MICROGRIDS FOR MILITARY OPERATIONS
No full textModern warfighters rely heavily on fast, accurate information to conduct all forms of military operations. It is critical that deployed Command and Control centers have reliable power for conduct of military operations and serve as a central node for information relay. For military deployments outside areas with prepared infrastructure for utility power, or in locations with no reliable utility power, stable power supply from microgrids for operations will be required. Such operations range from peacekeeping to humanitarian aid and disaster relief operations. Although such microgrids are generally reliable at providing stable power, their resilience to disruption is poor. Common interruptions include natural disasters like earthquakes, and man-made causes like cyber or physical attacks. Previous research into microgrid resilience evaluation efforts center on theoretical modeling of total electrical microgrid loading, critical electrical load prioritization, assumed capacity of renewable energy sources and their associated energy storage systems, and assumed availability of emergency generators. Experimental data from a scaled microgrid system was collected and assessed against the results from two simulation models by Peterson and Anderson. The results validate the simulation models and highlight some areas for model improvement.Approved for public release. Distribution is unlimited.Military Expert 5, Republic of Singapore Air Forc
FEASIBILITY ANALYSIS OF A MOBILE MICROGRID DESIGN TO SUPPORT DOD ENERGY RESILIENCE GOALS
No full textThis research investigates the feasibility of using mobile microgrids to increase energy resilience on Department of Defense installations. The primary question examined is whether a standardized mobile microgrid, constrained within an ISO TriCon container, can provide the necessary power for small critical sites with an average 10 kW load with similar resilience to a customized single load microgrid or emergency backup generator. Key assumptions for this research are that power outages may be accompanied by a fuel-constrained environment (e.g., natural disaster that restricts fuel transport), that an existing installation microgrid is in place, and that the risk of outages does not warrant the development of redundant customized single load microgrids for each critical load. Feasibility was examined by constructing an architectural design that attempts to find a satisfactory combination of commercial off-the-shelf components for battery energy storage, photovoltaic power, and generator power within the constraints of an 8 ft x 6.5 ft x 8 ft shipping container. That design was modeled and simulated over a two-week period using Global Horizontal Index solar irradiation data, and a randomized average 10 kW load. Results of the model were used to analyze the feasibility of the system to meet the load while reducing dependency on fuel resources. Trade-offs between a customized single load microgrid and standardized mobile microgrid are discussed.Approved for public release. Distribution is unlimited.Major, United States Arm
