The new trends and developments in the novel functional materials and material research innovations presented at the 3rd Global Conference on Materials Science and engineering (CMSE2014), which was held on 20-23 October 2014 in Shanghai, China, is discussed. R. Toyoda, M. Tawata, M. Hashimoto, and Y. Matsumura presented 'Internal stress control of transition-metal thin films', where the effects of ion bombardment parameter Pi on the internal stress of thin films were evaluated. X.G. Wang, Z.L. Chen, and X.Y. Wang presented their study 'Measurement of the interface characteristic based on ultrasonic longitudinal wave', which provided a lucrative alternative to conventional ultrasonic techniques, since it allows one to avoid the mutual superposition of reflected waves at the same thin coating interface. P. Wang and C.Y. Zhao presented their 'Study on reducing railway noise by porous concrete sound-absorbing panel', which is crucial for noise reduction near the railway lines. In the paper entitled 'Numerical study on the heat preservation of the ladle used for twin-roll strip casting', J.H. Dong, M. Chen and N. Wang developed a 3D mathematical model, in order to analyze the heat transfer and temperature drop on the ladle using the finite volume method.

Artificial flowers are mainly static objects. If we can make them movable with actuating mechanisms, sensors and controllers, this will make them more lively and entertaining. The aim of this paper is to develop artificial flower ornaments with dynamic, modular, programmable and green-energy characteristics. The dynamically artificial flower ornaments show the performances: bending of stems, blooming of petals, spreading of fragrance and flapping of butterflies. Besides, solar power to simulate photosynthesis (it is just an analogy to actual photosynthesis) will be used to energize the dynamically artificial flower ornaments. Instead of using conventional mechanisms and electromagnetic motor to actuate the flower ornaments, we use shape memory alloy (SMA) as actuators and pulse width modulation (PWM) as drive circuit to avoid complication, lager volume and noise generation of the components. Four types of the SMA actuators are made of SMA wire (Ti50%-Ni45%-Cu5%) with one way shape memory effect and 0.6mm in diameter. The performance of each SMA actuator is evaluated. By using PWM, the SMA actuators have high response time and low energy consumption in acting cycle.

Statechart has been utilized as a visual formalism for the modeling of complex and interactive systems for its illuminating features on describing properties of causality, concurrency, and synchronization. This paper presents the application of satechart to the modeling, design and implementation of an elevator system, whose system behavior involves aggregating complexity of state descriptions, and imposition of underlying control policy. Based on the operational flow of an elevator, we derive the associated statechart model by looking into the inherent hierarchical structure of the elevator. The advantage of the proposed approach is the clear presentation of system behavior in terms of conditions and events that cause the transitions in system dynamics. Implementation of the controlled elevator based on the modeled statechart is also presented.

One key, but little documented and empirically supported, input in the ship design cycle is the expected operating speed profile. This real-world constraint affects many decisions regarding bull form and power systems, from fuel tanks to main propulsion and ship's service machinery selection and operation. These decisions, in turn, ripple through the design of a ship in ways that are often bard to discern, but clearly impact acquisition and life cycle costs. Recent studies of DDG 51 operating speed profiles demonstrate that the Navy regularly operates with speed profiles considerably different than used to design the ship. In general, warships operate in standard engine order telegraph increments (e.g., Ahead 2/3) and at lower speeds than designed for.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central Control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.

This paper reviews an inexpensive statistical-sampling methodology that can be used to determine the attrition rates of certain types of shipboard equipment. The methodology relies on surveys that are conducted in conjunction with regularly scheduled ship visits over a period of time and a statistical analysis of the survey results. The statistical technique allows for reasonably accurate estimates to be made of attrition rates. The specific example cited in this paper is related to galley-type refrigeration equipment, such as salad chillers, beverage dispensers, et cetera. In the case of galley-type refrigeration equipment, the Navy needs to know whether the Fleet's inventory of equipment relying on Class I Ozone-Depleting Substances (ODSs) will be replaced through natural attrition by the end of fiscal year (FY) 2005, at which time supplies of ODS-based refrigerants will no longer be available for use by ship galleys. This paper outlines the process used to gather data, the analysis of the data, and concludes that the Navy's inventory of galley equipment using Class I ODSs will be replaced through natural attrition by the end of FY05. The methodology reviewed by this paper has wider applications. For various types of shipboard equipment, the methodology can also be used to estimate with reasonable accuracy life expectancies, configurations, conditions, and other items of interest.

The domestic production of the most powerful ozone-depleting substances (ODSs) has permanently ceased and the abundant supplies of a number of refrigerants, fire-fighting agents, and solvents, once taken for granted, are now a thing of the past. The Navy has adopted a successful strategy for addressing the threat posed by the unavailability of ODSs. That strategy includes relying on a strategic reserve of ODSs. Considering that the strategic reserve will play a critical role in sustained Fleet operations into the middle of the century, it is important to record the history of the reserve and to document lessons learned in order to educate future generations that may face similar challenges. This is the third of three papers that cover all aspects of the Navy's strategic reserve of ODSs. Breslin (1999) documented the history of the Navy's effort to size, establish, and monitor a reserve designed to support Fleet operations until the middle of the century. Breslin, Smith, and Toms (2000) addressed in detail the process used to estimate the required size of the reserve, including the survey method, statistical analyses, and sizing algorithms. This paper discusses the Navy's plan for monitoring the Navy's strategic reserves of ODSs and describes the methods used in the monitoring process. In particular it discusses the underlying assumptions and statistical techniques associated with the Navy's prediction of the expected drawdown of the reserves. A comparison of actual data, collected since the strategic reserves began operations in 1995, with the predicted reserve drawdown, is included in the paper.

Material characterization tests were performed at the U.S. Naval Academy to identify a toughened laminate for the new Navy 44-foot sail training vessels. After preliminary analysis using classical lamination theory, four different cores, five laminates and seven resin systems were tested in UV exposure, four-point bending, lateral panel pressure, and simulated bow impact. Results showed substantial improvements in strength, toughness, cost and weight were possible over the existing laminate, with the lightest acceptable laminate yielding a weight savings equivalent to 3.5% of the vessel's displacement.

The U.S. Coast Guard is in the concept exploration phase of its Integrated Deepwater System (IDS) acquisition project. This project will define the next generation of surface, air and command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) assets used to perform the Coast Guard's missions in the IDS environment (>50 NM off the U. S. coastline). As part of early technology investigations, the needs exist to: (1) analyze the workload requirements of the IDS, (2) identify alternative means to perform ship's work, and (3) optimize ship manning consistent with ship workload, performance criteria, and the available tools and equipment aboard. To reduce shipboard work requires an understanding of the mission and support requirements placed on the vessel and crew, how these requirements are currently met, and how requirements might otherwise be met to reduce workload and crew size. This study examined currently implemented workload and manpower reducing approaches of commercial maritime fleets, U.S. and foreign navies, and foreign coastguards. These approaches were analyzed according to evaluation criteria approved by the IDS acquisition project team. From this, strategies for shipboard work reduction that may be considered for adoption by the IDS were identified and analyzed according to performance and costs factors. Ten workload-reducing strategies were identified: damage control, bridge, multiple crewing, engineering, risk acceptance, modularity, deck, enabling technologies, ship/personnel readiness, and operability and maintainability.

The domestic production of the most powerful Ozone-Depleting Substances (ODSs) has permanently ceased and the abundant supplies of a number of refrigerants, fire-fighting agents, and solvents, once taken for granted, are now a thing of the past. ne Navy has adopted a successful strategy for addressing the threat posed by the unavailability of ODSs. That strategy includes relying on a strategic reserve of ODSs. Considering that the strategic reserve will play a critical role in sustained fleet operations well into the next century, it is important to record the history of the reserve and to document lessons learned in order to educate future generations that may be faced with similar challenges. This is the second of three papers that will cover all aspects of the Navy's strategic reserve of ODSs. The first paper documented the history of the Navy's effort to size, establish, and monitor a reserve designed to support fleet operations until-the middle of the next century (1). This paper addresses in detail the process used to estimate the required size of the reserve, including the survey method, statistical analyses, and sizing algorithms. The third paper will discuss the development of the plan for monitoring the reserve including the control mechanisms, regression methods, and statistical-process-control techniques (2).
