Power generation and energy storage devices are essential components of the operational capabilities of the modern U. S. military. They are paramount to the tactical performance of advanced electronic systems such as Night Vision Goggles, GPS systems, and laser target designators. The modern “digitized” U.S. military relies extensively on these electronic technologies and others as they are fully integrated into combat environments. However, the demand for these electronic systems, as well as new tactical capabilities, is outpacing the supply of available power and energy devices. Recent studies from Iraq show that standard military power and energy systems, such as generators and batteries, were in high demand but short supply, which often limited operational speed and capabilities. In an effort to improve upon existing military power generation and energy storage devices, the Army’s Research, Development, and Engineering Centers (RDECs) are evaluating innovative technologies such as fuel cells for military applications. A variety of programs at the U.S. ARMY Communications-Electronics Research, Development, and Engineering Center (CERDEC) Fuel Cell lab are serving to fill the power and energy gap for soldier-based platforms. CERDEC serves as a test, evaluation, and program management center focused on transitioning integrated systems from the labs to the users. CERDEC has adopted a “systems of systems” approach to the development and testing of military fuel cell units and strives to develop completely packaged systems in order to rapidly transition fuel cell technology into the field. This paper will address current Army Communications-Electronics Research Development Engineering Center (CERDEC) fuel cell technology programs and their adaptation into military environments.

Abstract Background The American Geriatrics Society recommends against the use of certain potentially inappropriate medications (PIMs) in older adults. Prescribing of these medications correlates with higher rates of hospital readmissions, morbidity, and mortality. Vanderbilt University Medical Center previously deployed clinical decision support (CDS) to decrease PIM prescribing rates, but recently transitioned to a new electronic health record (EHR). Objective The goal of this study was to evaluate PIM prescribing rates for older adults before and after migration to the new EHR system. Methods We reviewed prescribing rates of PIMs in adults 65 years and older, normalized per 100 total prescriptions from the legacy and new EHR systems between July 1, 2014 and December 31, 2019. The PIM prescribing rates before and after EHR migration during November 2017 were compared using a U-chart and Poisson regression model. Secondary analysis descriptively evaluated the frequency of prescriber acceptance rates in the new EHR. Results Prescribing rates of PIMs decreased 5.2% (13.5 per 100 prescriptions to 12.8 per 100 prescriptions; p < 0.0001) corresponding to the implementation of alternatives CDS in the legacy EHR. After migration of the alternative CDS from the legacy to the new EHR system, PIM prescribing rates dropped an additional 18.8% (10.4 per 100 prescriptions; p < 0.0001). Acceptance rates of the alternative recommendations for PIMs was low overall at 11.1%. Conclusion The prescribing rate of PIMs in adults aged 65 years and older was successfully decreased with the implementation of prescribing CDS. This decrease was not only maintained but strengthened by the transition to a new EHR system.

Full textAbstract:
Purpose – The purpose of this paper is to provide a framework for the optimal design of queueing systems of call centers with delay information. The main decisions in the design of such systems are the number of servers, the appropriate control to announce delay anticipated. Design/methodology/approach – This paper models a multi-server queueing system as an M/M/S+M queue with customer reactions. Based on customer psychology in waiting experiences, a number of different service-level definitions are structured and the explicit computation of their performance measures is performed. This paper characterizes the level of satisfaction with delay information to modulate customer reactions. Optimality is defined as the number of agents that maximize revenues net of staffing costs. Findings – Numerical studies show that the solutions to optimal design of staffing levels and delay information exhibit interesting differences, especially U-shaped curve for optimal staffing level. Experiments show how call center managers can determine economically optimal anticipated delay and number of servers so that they could control the trade-off between revenue loss and customer satisfaction. Originality/value – Many results that pertain to announcing delay information, customer reactions, and links to satisfaction with delay information have not been established in previous studies, however, this paper analytically characterizes these performance measures for staffing call centers.

Full textAbstract:
The global center is a newly proposed graph concept. For a graph G = (V(G), E(G)), a set S ⊆ V(G) is a global distribution center if every vertex v ∈ V(G)\S is adjacent to a vertex u ∈ S with |N[u] ∩ S| ≥ |N[v] ∩ (V(G)\S)|, where N(v) = {u ∈ V(G)|uv ∈ E(G)} and N[v] = N(v) ∪ {v}. The global distribution center number of a graph G is the minimum cardinality of a global distribution center of G. In this paper, we investigate the global distribution center number for special families of graphs. Furthermore, we develop a polynomial time heuristic algorithm to find the set of the global distribution center for general graphs.

Full textAbstract:
The availability of freshwater is becoming a global concern. Because agricultural consumption has been increasing steadily, the mapping of irrigated areas is key for supporting the monitoring of land use and better management of available water resources. In this paper, we propose a method to automatically detect and map center pivot irrigation systems using U-Net, an image segmentation convolutional neural network architecture, applied to a constellation of PlanetScope images from the Cerrado biome of Brazil. Our objective is to provide a fast and accurate alternative to map center pivot irrigation systems with very high spatial and temporal resolution imagery. We implemented a modified U-Net architecture using the TensorFlow library and trained it on the Google cloud platform with a dataset built from more than 42,000 very high spatial resolution PlanetScope images acquired between August 2017 and November 2018. The U-Net implementation achieved a precision of 99% and a recall of 88% to detect and map center pivot irrigation systems in our study area. This method, proposed to detect and map center pivot irrigation systems, has the potential to be scaled to larger areas and improve the monitoring of freshwater use by agricultural activities.

Full textAbstract:
U-healthcare systems are based on a ubiquitous and wireless computing and communication environment. They are comprised of the U-healthcare management center, electronic medical records (EMR) system, and the associated services for users and patients. The U-healthcare management center performs continuous monitoring and provides support services in multiple areas, requiring careful allocation of the limited service resources to provide customized healthcare services for users of the mobile distributed system. When the number of locally connected users increases rapidly, a mobile allocation and distribution server can be imbalanced by the load on service resources, resulting in delayed services. This study proposes a dynamic load balancing model for reducing the load of users on service resources and supporting efficient response services in a mobile distributed system. The proposed dynamic load balancing model clusters the system resources of servers dynamically, according to each users' movement and time. The dynamic clustering of system resources uses wFCM (weighted Fuzzy C-Means), which changes the cluster center by transforming existing FCM (Fuzzy C-Means) from a fixed weight to a dynamic one. Using wFCM, the load balance can be maintained, based on the usage rate of service resources, such as CPU, memory, and network. In addition, the balance between QoS (Quality of Service) requests and network response times can be maintained by adding an abstraction layer between application services and network infrastructure. Therefore, when the proposed model is applied to a U-healthcare monitoring system, the system can perform near real-time monitoring of service users in the mobile distributed environment, and effectively address emergent situations. This study evaluates the response time of the implemented model in relation to the number of concurrently connected users, and confirms that the proposed model is faster in response and service processing than existing WLC (Weighted Least-Connection Scheduling) and FCM (Fuzzy C-Means).

SUMMARY: An ever-increasing volume of traffic on Croatian roads increases the volume of maintenance work. Road works negatively impact traffic mobility and road user safety, and also safety of the maintenance workers. Improving traffic mobility and safety is the key issue that all interested parties (planning and managing road works and those executing them) should address. Mitigation of negative effects is possible via certain expert system measures. Presented in the paper are the options provided by expert systems implemented in the road work zones as factors for improving road maintenance and safe traffic flow, as well as road workers safety. Introducing relevant data into the data base, an expert system is created providing the driver approaching a road work zone with a number of alternative routes. Also shown is a driving diagram for road work zones with special focus on slowing down speed upon entering the road work zone. The results show that the implementation of expert systems based on relevant data would significantly facilitate traffic management in road work zones and improve the safety of traffic and road workers, as well as the workers' efficacy.

Full textAbstract:
The increase in business competitiveness forces companies to adopt new technologies to redesign business processes, improve products, and support organizational changes necessary for better performance. The literature on Competitive Intelligence (CI) touts its importance in providing corporate strategic vision to improve company competitiveness and success. To implement their strategic vision companies have to implement changes to their business processes, products, and/or to the organization itself. The voluminous body of literature on the management of change, including sub-areas such as Business Process Reengineering (BPR), Total Quality Management (TQM), and product improvement, implicitly or explicitly propose that company strategic intelligence is a pre-requisite for change, and that effective Information Systems (IS) support is a critical requirement for implementing change. There is some empirical evidence supporting these two hypotheses based on U.S. business organizations and there is little reason to believe that the relationships do not hold for Japanese companies. Whether or not U.S. and Japanese organizations are different in any way along these important variables is an interesting question. A field test of how effectively U.S. and Japanese business organizations are identifying strategic problems and opportunities, how effectively they implement business changes, and use IS technology to do so, was undertaken to empirically explore any differences. Despite the relatively small sample size, the results corroborate the importance of competitive intelligence and IS support for effectively implementing business change in U.S. and Japanese companies. The findings indicate, on the average, American companies are more effective in providing IS support for business change and Japanese companies are more effective in CI activities.

<em>Abstract</em>.—Habitat for striped bass <em>Morone saxatilis</em>, hybrid striped bass, salmonids, and other coolwater and coldwater fishes can be limiting in stratified reservoirs during summer and early autumn as surface water temperatures increase above tolerable ranges and deeper waters are depleted of dissolved oxygen (DO). Usable habitat can be increased in these reservoirs using oxygen diffusers to increase DO concentrations in the cooler, deeper waters. Several oxygen diffuser systems are currently in operation. Some of the systems were originally designed to increase DO in hydropower reservoir releases, but have also created fish habitat as a result of the diffuser system’s efficient oxygen transfer capabilities in the reservoir. Several other systems are operated to improve water quality in the reservoir for water supply, and two systems have specific fish habitat maintenance goals. Improvements in DO for fish have been obtained at Calaveras Reservoir, California by the San Francisco Public Utility Commission, and fish studies at this reservoir are currently underway. In North Twin Lake, Washington, the Colville Confederated Tribes and Washington State University have documented improved trout habitat and reduced sulfide concentrations. Oxygenation of cool, deep water is now a proven technology that can alleviate summertime thermal and oxygen stress on striped bass and hybrid striped bass and can minimize habitat-related mortalities. The technology is being implemented specifically for striped bass with a large installation in J. Strom Thurmond Reservoir, South Carolina, for the Savannah District of the U. S. Army Corps of Engineers.

It has exceptional landscape conditions, highly productive lands, and a large percentage of the water reserve that supplies the region and the country, giving the territory an economic center character since the colony. These physical values make part of collective imagination as a recreation area and an opportunity for development in the 1960s, according to the construction of large national infrastructure works. At the same time, it was object of armed conflict in the 1980s and 1990s, and more recently, directly related to the spatial dynamics of the region: unplanned urban expansion, changes in land use and vegetation cover, with effects on the cultural landscape. In a post-conflict situation, the economic strategies of different actors trust on tourism as a social-spatial management strategy to improve the territory. However, the identity of rurality shows spatial imbalances without recognizing elements of historical construction whose legacies must be revealed to ensure equitable development. To do this, we propose an approach from the cultural landscape in a revision of the historical, symbolic and relational transformation through five systems (anthropic, productive, political, symbolic and spatial), analyzing competitiveness, tourism, landscape and social management, in different scales and during three historical moments.

Full textAbstract:
Five years after the introduction of gas turbine propulsion in major U. S. Navy combatants, the engineering training pipeline, populated with cross-rates primarily from the existing machinist, engineman, and electrical ratings, consisted of a series of contractor developed block courses operationally centered around the propulsion and electrical control consoles. The rapid introduction of new ships in the late seventies and eighties required an accelerated training pipeline and the use of mostly apprentice candidates directly from recruitment. This increased need, the recognition in the fleet that existing training was not providing system knowledge, and the construction of a gas turbine training hot plant precipitated the development of a new training curriculum. Course development was derived from documentation which dictates plant operation: the equipment/system design; the Preventive Maintenance System (PMS); the Engineering Operating Sequencing System (EOSS); Fleet commander engineering management programs; and the Ships’ Manning Document (SMD). Using a disciplined approach, essential student performance objectives were defined and necessary learning objectives developed from the above documentation. The scope of the course encompassed the “cradle to grave” concept from apprentice training through journeyman and supervisor, and necessitated incremental and refresher training throughout the career of the gas turbine mechanic and electrician.

Full textAbstract:
The former production site of NUKEM where nuclear fuel-elements were developed and handled from 1958 to 1988 was situated in the centre of an industrial park for various activities of the chemical and metallurgical industry. The size of the industrially used part is about 300.000m2. Regulatory routine controls showed elevated CHC (Chlorinated Hydro-Carbons) values of the ground water at the beginning of the 1990’s in an area which represented about 80.000 m2 down-gradient of locations where CHC compounds were stored and handled. Further investigations until 1998 proved that former activities on the NUKEM site, like the UF6 conversion process, were of certain relevance. The fact that several measured values were above the threshold values made the remediation of the ground water mandatory. This was addressed in the permission given by the Ministry for Nuclear Installations and Environment of Hesse according to §7 of the German atomic law in October 2000 [1]. Ground water samples taken in an area of about 5.000 m2 showed elevated values of total Uranium activity up to between 50 and 75 Bq/l in 2002. Furthermore in an area of another 20.000m2 the samples were above threshold value. In this paper results of the remediation are presented. The actual alpha-activities of the ground waters of the remediation wells show values of 3 to 9Bq/l which are dominated by 80 to 90% U-234 activity. The mass-share of total Uranium for this nuclide amounts to 0,05% on average. The authority responsible for conventional water utilisation defined target values for remediation: 20μg/l for dissolved Uranium and 10μg/l for CHC [2]. Both values have not yet been reached for an area of about 10.000 m2. The remediation process by extracting water from four remediation wells has proved its efficiency by reduction of the starting concentrations by a factor of 3 to 6. Further pumping will be necessary especially in that area of the site where the contaminations were found later during soil remediation activities. Only two wells have been in operation since July 2002 when the remediation technique was installed and an apparatus for direct gamma-spectroscopic measurement of the accumulated activities on the adsorbers was qualified. Two further remediation wells have been in operation since August 2006, when the installed remediation technique was about to be doubled from a throughput of 5 m3/h to 10 m3/h. About 20.000 m3 of ground water have been extracted since from these two wells and the decrease of their Uranium-concentrations behaves similar to that of the two other wells being extracted since the beginning of remediation. Both, total Uranium-concentrations and the weight-share of the nuclides U-234, U-235 and U-238 are measured by ICP-MS (Inductively Coupled Plasma – Mass Spectrometry) besides measurements of Uranium-Alpha-Activities in addition to the measurement of CHC components of which PCE (Perchlor-Ethene) is dominant in the contaminated area. CHC compounds are measured by GC (Gas Chromatography). Down-gradient naturally attenuated products are detected in various compositions. Overall 183.000m3 of ground water have been extracted. Using a pump & treat method 11 kg Uranium have been collected on an ion-exchange material based on cellulose, containing almost 100 MBq U-235 activity, and almost 15 kg of CHC, essentially PCE, were collected on GAC (Granules of Activated Carbon). Less than 3% of the extracted Uranium have passed the adsorber-system of the remediation plant and were adsorbed by the sewage sludge of the industrial site’s waste water treatment. The monthly monitoring of 19 monitoring wells shows that an efficient artificial barrier was built up by the water extraction. The Uranium contamination of two ground water plumes has drastically been reduced by the used technique dependent on the amounts of extracted water. The concentration of the CHC contamination has changed depending on the location of temporal pumping. Thereby maximum availability of this contaminant for the remediation process is ensured. If locations with unchanged water quality are detected electrochemical parameters of the water or hydro-geologic data of the aquifer have to be taken into further consideration to improve the process of remediation.

Fresh water is one of the few resources which is scarce and has no replacement; it is also closely coupled to energy consumption. Fresh water usage for power generation and other cooling applications is well known and accounts for 40% of total freshwater withdrawal in the U. S[1]. A significant amount of energy is embedded in the consumption of water for conveyance, treatment and distribution of water. Waste water treatment plants also consume a significant amount of energy. For example, water distribution systems and water treatment plants consume 1.3MWh and 0.5MWh[2], respectively, for every million gallons of water processed. Water consumption in data centers is often overlooked due to low cost impact compared to energy and other consumables. With the current trend towards local onsite generation[3], the role of water in data centers is more crucial than ever. Apart from actual water consumption, the impact of embedded energy in water is only beginning to be considered in water end-use analyses conducted by major utilities[4]. From a data center end-use perspective, water usage can be characterized as direct, for cooling tower operation, and indirect, for power generation to operate the IT equipment and cooling infrastructure[5]. In the past, authors have proposed and implemented metrics to evaluate direct and indirect water usage using an energy-based metric. These metrics allow assessment of water consumption at various power consumption levels in the IT infrastructure and enable comparison with other energy efficiency metrics within a data center or among several data centers[6]. Water consumption in data centers is a function of power demand, outside air temperature and water quality. While power demand affects both direct and indirect water consumption, water quality and outside air conditions affect direct water consumption. Water from data center infrastructure is directly discharged in various forms such as water vapor and effluent from cooling towers. Classification of direct water consumption is one of the first steps towards optimization of water usage. Subsequently, data center processes can be managed to reduce water intake and discharge. In this paper, we analyze water consumption from data center cooling towers and propose techniques to reuse and reduce water in the data center.

Abstract Introduction In the United States, the Bureau of Safety and Environmental Enforcement (BSEE) requires an offshore lease operator to implement a Safety and Environmental Management System (SEMS), and to have it audited at least once every 3 years to evaluate its compliance to the regulatory requirements detailed in 30 CFR 250, Subpart S. The first round of these SEMS audits, which concluded in 2013, was executed using varying audit styles – from system audits through to compliance audits. These varying audit styles, in turn, lead to differing types output, levels of detail, format and presentation.These diverse approaches may have been due, at least in part, to disparities in the expectations of stakeholders, differing interpretations of the use of the Center for Offshore Safety's (COS) SEMS Audit Protocol tools, use of other audit protocols, the experience-level of individual auditors, and the newness of the regulation. System audits are intended to be a holistic assessment of a system, its elements, and how the elements work together to achieve system objectives. Compliance audits, on the other hand, are intended to assess adherence to specific requirements. This white paper proposes that both types of audits should be used in tandem to reduce risk and increase confidence that a management system, and its verification programs, is operating as designed and meeting regulatory and company requirements.

Sažetak: U radu se obrađuju metode i načini upravljanja rizicima karijere u poslovima kvalitete. Prošlo je više od 30 godina od kada se intenzivno implementiraju sustavi upravljanja prema ISO normama, a usporedo s time su se profilirala brojna zanimanja u kojima pojedinci vide razvoj svoje profesionalne karijere. Poseban poticaj i usmjerenje razvoja određenih profesija u kvaliteti dala je EOQ (Europska organizacija za kvalitetu) koja je istražujući potrebe organizacija za takvim znanjima i profesijama razvila sheme za školovanjem profesionalnog osoblja u kvaliteti. Nakon određenog razvojnog perioda postalo je vrlo aktualno da se otpočnu izučavati rizici koji prate razvoj karijere profesionalnog osoblja u kvaliteti te da se osvijesti što može poći po zlu u takvom opredjeljenju. Istraživanja i pisani izvori o ovoj temi su skromni pa su se autori oslanjali na izvore razvoja karijere u drugim poslovima, a korišteni su i pokazatelji analiza provedene edukacije i intervjui vođeni s polaznicima edukacije za kvalitetu koje u posljednjih 30 godina vodi OSKAR d.o.o. Autori su svjesni da se o toj problematici ne mogu napisati gotovi recepti, ali se mogu osvijestiti metode i način kako izbjeći zamke rizika u planiranju vlastite karijere u kvaliteti. Autori su također svjesni činjenica da u državama koje su u tranziciji (na koje se odnosi ovaj rad) vlada stanje opće nesigurnosti, a vrlo često se nesigurna gospodarska stanja reflektiraju na status i karijeru profesionalnog osoblja u kvaliteti. Pored svega toga vrijeme je da se otpočne ozbiljnije razmatrati i istraživati upravljanje rizicima karijere u poslovima kvalitete. Abstract: The paper deals with methods and ways of managing career risks in quality jobs. It has been more than 30 years since the management systems according to ISO standards have been intensively implemented, and in parallel, numerous occupations have been profiled in which individuals see the development of their professional careers. A special impetus and direction for the development of certain professions in quality was given by EOQ, which, researching the needs of organizations for such knowledge and professions, developed schemes for training professional staff in quality. After a certain period of development, it has become very important to start studying the risks that accompany the career development of professional staff in quality and to become aware of what can go wrong in such a commitment. Research and written sources on this topic are very modest, so the authors relied on sources of career development in other jobs, and used indicators of analysis of education and interviews conducted with participants in quality education conducted in the last 30 years by OSKAR Ltd. The authors are aware that ready-made recipes cannot be written on this issue, but methods and ways to avoid risk traps in planning one's own career in quality can be made aware. The authors are also aware of the fact that in countries in transition (to which this paper refers) there is a state of general insecurity, and very often uncertain economic conditions are reflected in the status and career of professional staff in quality. In addition to all this, it is time to start seriously considering and researching career risk management in quality jobs.

Full textAbstract:
Abstract: Risk management is an indispensable part of the financial market and banking sector and consists of the identification of various forms of risk to which banking operations are exposed. Accelerated and constant market development, globalization and internationalization of the market and new technologies bring new challenges but also risks. Risk management in today's dynamic environment brings with it numerous obstacles but also poses new challenges and opportunities for companies, which implies the establishment of appropriate corporate management and risk culture. Through an adequate and appropriate risk management system tasks and responsibilities of the supervisory and management body and senior management, the system of internal controls, control functions, organizational chart and tasks of individual organizational parts and functions are defined. The banking sector and banking operations are exposed to many risks where several risks occur simultaneously, there is no risk that is only one or placement that carries only one risk, while an additional problem that the bank faces is the quantification of risk. Identifying, measuring, assessing, managing, monitoring and reporting on risks implies defining a risk management strategy which defines the basic guidelines for medium-term risk assumption and the development of risk management and control systems. The risk management strategy is aimed at defining a set of basic standards for sustainable and effective management and control of all identified risks to which the bank is or could be exposed in its operations, taking into account the quality of implementation and compliance with business plans and objectives. The aim of this paper is to present the potential risks that arise in regular banking operations and to show banks risk management system in order to increase the quality of bank operations. Sažetak: Upravljanje rizicima neizostavan je dio financijskog tržišta odnosno bankarskog sektora, a sastoji se od identifikacije različitih oblika rizika kojim je izloženo bankarsko poslovanje. Ubrzani i konstantni razvoj tržišta, globalizacija i internacionalizacija tržišta, nove tehnologije sa sobom nose nove izazove ali rizike. Upravljanje rizicima u današnjem dinamičnom okruženju nosi sa sobom brojne prepreke ali i stavlja pred poduzeća nove izazove i prilike što podrazumijeva uspostavu odgovarajućeg korporativnog upravljanja i kulture rizika. Upravo kroz adekvatan i odgovarajući sustav upravljanja rizicima definiraju se uloge, zadaci i odgovornost nadzornog i upravljačkog tijela i višeg rukovodstva, sustav unutarnjih kontrola, kontrolne funkcije, organizacijska shema i poslovi pojedinih organizacijskih dijelova i funkcija. Bankarski sektor i bankarsko poslovanje izloženo je mnogobrojnim rizicima gdje se nekoliko rizika javlja istovremeno, ne postoji rizik koji je samo jedan ili plasman koji sa sobom nosi samo jedan rizik dok je dodatni problem s kojim se banka susreće kvantifikacija rizika. Utvrđivanje, mjerenje, procjenjivanje, ovladavanje, praćenje i izvještavanje o rizicima podrazumijeva definiranje strategije upravljanja rizicima kojom se definiraju osnovne smjernice za srednjoročno preuzimanje rizika te razvoj sustava upravljanja i kontrole rizicika. Strategije upravljanja rizicima usmjerena je na definiranje skupa osnovnih standarda za održivo i učinkovito upravljanje i kontrolu svih identificiranih rizika kojima banka je ili bi mogla biti izložena u svojem poslovanju, vodeći računa o kvaliteti primjene i usklađenosti istih s poslovnim planovima i ciljevima organizacije. Cilj ovog rada je izložiti potencijalne rizike koji se javljaju u redovnom bankarskom poslovanju i prikazati načine na koje se banka nosi s njima, odnosno upravljanja rizicima u funkciji povećanja kvalitete poslovanja.

Full textAbstract:
The VIVACE (Vortex Induced Vibration for Aquatic Clean Energy) Converter was introduced at OMAE2006 as a single, smooth, circular-cylinder module. The hydrodynamics of VIVACE is being improved continuously to achieve higher density in harnessed hydrokinetic power. Inter-cylinder spacing and Passive Turbulence Control (PTC) through selectively located roughness are effective tools in enhancement of Flow Induced Motions (FIMs) under high damping for power harnessing. VIVACE Converters consist of multi-cylinder modules. Single cylinders harness energy at high density even in 1knot currents. For downstream cylinders questions are raised on energy availability and sustainability of high-amplitude FIM. Through PTC and inter-cylinder spacing, strongly synergetic FIM of 2/3/4 cylinders is achieved, harnessing hydrokinetic energy with increased footprint density. Two-cylinder smooth/PTC and four-cylinder PTC systems are tested experimentally. Using the “PTC-to-FIM” map developed in previous work at the Marine Renewable Energy Laboratory (MRELab), PTC is applied and cylinder response is measured for the following parameter ranges: In-flow center-to-center distance 1.63•D–5.00•D (D = diameter), transverse center-to-center distance 0.5•D–1.5•,D, Re ∈[28,000–120,000], m* ∈[1.677–1.690], U ∈[0.36m/s–1.45m/s], aspect ratio l/D = 10.29, and m*ζ ∈[0.0283–0.0346]. All experiments are conducted in the Low Turbulence Free Surface Water (LTFSW) Channel of MRELab. Amplitude spectra and broad filed-of-view (FOV) visualization help reveal complex flow structures and cylinder interference undergoing VIV, interference/proximity/wake/soft/hard galloping.

Full textAbstract:
Health management of a machine, such as a gas turbine engine, offers the potential benefits of efficient operations planning and the reduced cost of ownership. It requires a tight integration of major health management functions, such as trending, failure identification, forecasting, life prediction, operations and maintenance planning. This paper introduces a suite of plug-in tools that enhance the condition monitoring and health management capabilities of operational (or legacy) systems. One of these systems is the U. S. Air Force Comprehensive Engine Trending and Diagnostics System (CETADS), which has been used as the baseline for the development of the tools. These tools are collectively called the Intelligent Condition-based Engine/Equipment Management System (ICEMS). These tools are configured as software modules, which can be incorporated into an operational health management system individually or as a group. ICEMS modules implement the advanced algorithms containing artificial intelligence, statistical, model-based analysis techniques, and RCM practices. Although these modules have been developed and tested using data from the Pratt & Whitney F100-PW-220 engine in service at Luke Air Force Base, the modules are also generalized to cover many generic machines (or equipment).
