Nowadays, the main problem we found in most Smartphones is the poor battery life when using applications that make an intensive use of connectivity services. This becomes a serious problem in specific applications such as telemedicine;where services such as WiFi and 3G connection are the largest consumers of energy, but are essential for the transfer of data required by these applications. This paper examines different energy consumption studies on mobile devices via WiFi and 3G. After this analysis, we propose a strategy for choosing the network with lower energy consumption based on the characteristics of the data transfer that the application requires. © 2013 Infonomics Society.

With the rapid development of technology, the use of social media by the public, especially among young people, is increasing. One of the social media platforms currently used by young people is the TikTok application. It is a video-based TikTok feature accompanied by music, writing, and pictures that are considered attractive, so teenagers like it to show their existence and self-disclosure. Therefore, this study aims to examine the intention of users to disclose their privacy. As the basis of the theory, this study deployed the privacy calculus theory, where the perceived benefits and perceived risks play crucial roles in the intention to disclose their privacy. The study successfully collected 369 responses. The empirical findings indicated that only the relationship between Perceived Personalization (PP) and Perceived Risk (PR) was not supported. However, all the remaining hypotheses were supported. These findings emphasize how several complicated variables influence social media users' intentions to disclose their privacy. When people feel in control of their privacy settings and see significant benefits, they are more likely to divulge personal information;nevertheless, perceived risks can greatly discourage users. © 2024 IEEE.

Regulations governing the discharge of sewage from ships have been in force since the early 1970's. In response, the marine industry has developed ever more complex systems and processes for managing these wastes. The first compliance method involved holding wastes until they could be legally discharged;as technology advanced, treatment systems were developed and installed to enable discharge within regulated waters. As the size and number of ships as increased with maturation of the ocean tourism business, more restrictive regulations have been enacted to minimize the impact on sensitive waters. The trend is toward increasing regulation of both sewage and graywater. The most recent action occurred on 12 October 2005 when the Governor of California signed into law Senate Bill 771 regulating most ship liquid discharges within state waters. This paper describes the development of an innovative advanced wastewater treatment technology, based on advanced oxidation, bearing in mind the lessons learned from systems developed by industry over the past thirty years.

The state of Wisconsin and state of Hawaii are the only states in the nation to have offered MentorNet membership to all public universities and technical colleges. This innovative partnership highlights a new model to launch MentorNet on college campuses. MentorNet, the E-Mentoring Network for Diversity in engineering and Science and an award-winning nonprofit e-mentoring organization, offers a proven effective means to connect students (protégés) in science, technology, engineering, and math (STEM) majors with professionals (mentors) in industry, government and higher education. Since mentoring is recognized as an important engagement strategy to encourage women and girls to pursue STEM education and careers, other states can benefit from the story of the Wisconsin and Hawaii collaboration. Hawaii's Maui Economic Development Board and Wisconsin's Milwaukee School of engineering have partnered under a Women in Technology grant from the U.S. Department of Agriculture Cooperative State Research, Education, and Extension Service. This grant is to encourage women and girls in rural areas to pursue STEM education and careers. Because students at the Hawaii and Wisconsin partner campuses were enthusiastic about their MentorNet experience, the Women in Technology grant funded a two-year contract to waive membership fees for MentorNet for all four-year and two-year University of Wisconsin system and Wisconsin Technical College system campuses;30 institutions could potentially participate. One of the aims of this program was to encourage more technical/community colleges to partner with MentorNet, broadening the range of mentoring opportunities for the diverse population of students who attend such schools. To promote MentorNet participation in the Wisconsin systems, a collaborative team from Hawaii, Milwaukee School of engineering, MentorNet, the University of Wisconsin system, and the Wisconsin Technical College system held a one-day orientation training in August 2005.

NAVAL ENGINEERS JOURNAL 1985年第5期97卷 139-146页

作者： DONOVAN, MR MATTSON, WS Michael R. Donovanis a 1974 graduate of the United States Naval Academy where he received his undergraduate degree in naval architecture. In 1975 he received a master of science degree in naval architecture and marine engineering from the Massachusetts Institute of Technology. After completing the Navy's nuclear power training program he served as machinery division officer in USSBainbridge (CGN-25) and chemistry and radiological controls assistant in USSLong Beach (CGN-9). He successfully completed the Navy's surface warfare officer qualification and passed the nuclear engineer's examination administered by Naval Reactors. He was then assigned to the Ship Design and Engineering Directorate (SEA-05) Naval Sea Systems Command as head systems engineer on the DDG-51 ship design project where he received the Navy Commendation Medal for outstanding performance. He is currently with Solar Turbines Incorporated as manager ship integration and integrated logistic support for the Rankine cycle energy recovery (RACER) system. Mr. Donovan has lectured at Virginia Polytechnic Institute teaching marine engineering and has given presentations on ship design at various symposiums and section meetings for both ASNE and SNAME. He has been a member of ASNE and SNAME since 1972 and is registered as a professional engineer in California and Virginia. Wayne S. Mattsonreceived his B.S. degree in mechanical engineering from Western New England College in 1972. Following graduation he attended Naval Officer Candidate School and was subsequently assigned as a project officer to COMOPTEVFOR where he was responsible for technical and operational test plans their execution and final equipment appraisal. Following a tour as engineering officer aboard the USSNespelen (AOG-55) he was assigned as commissioning MPA aboard the USSElliot (DD-967) the fifthSpruanceclass destroyer. For the past six years he has been employed by Solar Turbines Incorporated in program management within the advanced development department. He is currently

There is a great deal of emphasis currently in the Navy on the issues of reliability and maintainability. If a system or component is out of commission, it obviously cannot perform its mission. Thus, systems and components must be reliable, with low failure rates, and maintainable, with short repair times when the system does become inoperable. To be effective, these attributes must be incorporated into new ship systems early in the design stage. The Rankine cycle energy recovery (RACER) system is a heat recovery steam cycle designed to recover energy from the exhaust of an LM2500 gas turbine for augmentation of a ship's propulsion system. The RACER system provides several advantages to a gas turbine powered ship, one of which is improved fuel efficiency for significant annual fuel savings. This saving does not come free, however, since, in general, any additional system installed in the ship will have some maintenance requirements. In keeping with the Navy's current emphasis, a key philosophy in the design of the RACER system has been to minimize this maintenance burden. After a brief description of the RACER system and its design philosophy, the techniques being used during the design phase to minimize the maintenance burden on the fleet are presented. Trade-off studies concerning acquisition versus life-cycle costs, including fuel and maintenance costs, are discussed. Innovations incorporated into this state-of-the-art system are reviewed with an emphasis on design for affordability.

This paper defines, develops and examines a set of generic analysis tools that can be applied to Models and Simulations at the systems engineering level of fidelity. The tools examine the performance and effectiveness of Sensors;Weapons;and Battle Management, Command, Control, Communications, Computers, and Intelligence ((BMCI)-I-4) systems and equipment. The Measures of Performance (MOPs), Measures of Effectiveness (MOEs) and Measures of Force Effectiveness (MOFEs) were extracted from the Modular Command and Control Structure Paradigm which was developed at the Naval Postgraduate School. The paradigm provides for the development of evaluation criteria (MOPs, MOEs, and MOFEs) in a framework that ensures the traceability of system performance and effectiveness to the system operational requirements as specified in the Operational Requirements Document (ORD). Also, the analysis tools provide insight and valid estimates of numerical measures of the defined system functionality threads, which represent the system's operational requirements as specified in the ORD. The tools are directly transferrable and applicable to test and evaluation exercise events which are conducted in support of the development and acquisition of systems and equipment. Once the levels of system performance have been defined, the Paradigm generates a quantitative database that becomes a useful tool in system tradeoffs and selection. Once the alternative system suites have been defined, the suites can be analyzed in terms of system functionality threads and their corresponding performance capabilities versus cost.

Mr. Mittura received a B.S. in electrical engineering from Penn State University in 1978 and an M.S. in engineering management from Catholic University of America in 1982. He is a licensed professional engineer with the State of Virginia. Mitchel S. Karp:cofounded K&K Software Engineering Inc. in February 1970. He is currently secretary/treasurer and senior system engineer. His involvement in combat systems began with NTDS in 1963. He has been involved in the Aegis Program since 1968 and has worked in all aspects of combat system development including computer programming tactical analysis software development and management. He has given several seminars on real-time software development and documentation. He currently is working under contracts to NSWCDD in the areas of combat system architecture and connectivity configuration management and documentation. Mr. Karp received a B.S. in engineering physics from Lehigh University in 1958.

The Navy's focus has shifted from global war scenarios to preparedness for the prospect of involvement in regional, littoral contingencies and conflicts. Operationally, shipboard personnel will need the ability to shift focus from the combat system multimission roles to that of only a single mission. From a development perspective, combat systems must accommodate a continual infusion of technology in a budget constrained environment. Combat system architecture is the single most important feature affecting combat system flexibility, from both an operational and developmental aspect. There is a fundamental partitioning of combat svstem functions into detect, command, and engage in a horizontal integration approach that enhances this needed flexibilitv. This fundamental partitioning is currently applied to individual weapon systems, but not to combat svstems as a whole. Instead, self-contained weapon systems are often developed and then vertically integrated to form a combat svstem, causing reduced flexibility. The battle organization is the principal driving requirement for combat system architecture. This paper shows that that the battle organization is best supported by a horizontally integrated combat system of detect, command, and engage. It concludes that a horizontally integrated combat svstem architecture of detect, command, and engage should be a candidate for future combat systems.

THE EVOLUTION OF MACHINERY CONTROL-systemS ABOARD UNITED-STATES-NAVY GAS-TURBINE SHIPS

引用

NAVAL ENGINEERS JOURNAL 1989年第3期101卷 102-113页

作者： PREISEL, JH The author:is the DDG-51 program manager at the Naval Ship Systems Engineering Station in Philadelphia. He graduated from the U.S. Naval Academy with a B.S. in marine engineering in 1972 and completed graduate studies at the Naval Postgraduate School in 1978. In addition to an initial sea tour aboard a destroyer he has served at Charleston Naval Shipyard and at NavSea in both ship design and modernization. He recently completed a short assignment as the NavSea representative at the G.E. Simulation and Control System Department during the design manufacturing and testing of the DDG-51 Machinery Control System. Commander Preisel is a member of ASNE Sigma Xi ASME and SNAME and is a registered professional engineer.

Almost 25 years ago, the U.S. Navy committed to gas turbines for propulsion and electrical power generation for surface combatants. Jet engines from the aerospace industry were “marinized” and specified for several designs. Today, there are over one hundred gas turbine powered surface ships; almost half also have gas turbine generators. This fundamental change, notably from steam to gas turbine power, brought with it a new philosophy in the way prime movers are controlled and monitored. Unmanned engineering spaces were a fundamental part of the new design. Direct thrust control in the hands of the helmsman was possible. Possibly the most profound effect was the introduction of electronics in the main engineering spaces on a large scale. Data buses for data logging and bell logging were used as a means to reduce the tedium of normal watch standing. Gas turbine machinery control systems have entered a second generation with the introduction of the DDG-51 class destroyer and the AOE-6 supply ship. Hard-wired analog interfaces have given way to digital interfaces over asynschronous multiplexed data buses. Dedicated pushbuttons and indicators have given way to keyboards and plasma displays. Single use microprocessors with firmware coding have given way to standard microcomputers and general high order language (HOL) software code. This paper will trace the control systems' evolution from the Spruance and Perry classes to today's gas turbine designs. An attempt will be made to draw a sense of direction from this evolution. An in-depth explanation of the DDG-51 control system will be offered, as well as suggestions as to the future of control systems for gas turbine ships. Particular emphasis will be placed on the man-machine interface and the maintenance philosophy for both the control system hardware and software.

A turning point occurred in naval engineering in 1972 when the U.S. N avy chose to use marine gas turbines for the propulsion of its new SPRUANCE and PERRY Class ships. This paper reviews the more than twenty years of experience with turbine technology and its design integration into combat ships needed to make that decision. It is concluded that the availability of a good second generation aircraft derivative engine with proven reliability and a strong commercial base, i.e., the LM-2500, was as important to the decision as was the predicted improved ship effectiveness and cost benefits. This paper discusses improvements that can be made to the twin engine, single gear, single propeller shaft system. Focusing only on this mechanical transmission concept, it addresses the impact of possible improvements to the engine, gear, and shafting. In particular, the paper discusses current LM-2500 related R&D efforts to: (a) obtain improved part-power fuel rates, (b) integrate with a reversing reduction gear, and (c) add on a waste heat recovery steam cycle. Looking ahead to the year 2000, this paper suggests that a successor to the ubiquitous LM-2500 will appear in the 15 MW power range to provide the next step in the evolution of the twin engine package. This new naval engine will most likely be based on an aircraft core that exists at present, such that it will have demonstrated its reliability and commercial potential through many hours of testing prior to its mid-1990 marine conversion. This new engine is expected to offer improved air flow, an excellent fuel rate (approaching a flat 0.30 LB/HP-HR), and effective maintenance monitoring, all at some expense in size, weight, and cost. The year 2000 engine will burn a liquid hydrocarbon fuel similar to JP-5 because of its aircraft origins. Combined with advances in gear and shafting technology, the full twin engine propulsion system of the year 2000 should be markedly lighter, smaller, and more efficient than today's units.
