Cost Control of the Marine Diesel Based on Value Engineering

Cost control is an important measure to improve economic benefit of enterprises, while the theory of value engineering (VE) is the best method to coordinate improving product performance with reducing the cost of production. It realizes the improvement of the value of product and economic benefit, and achieving the purpose of optimizing the cost structure. The theory of value engineering is innovatively applied to the study of cost control of the marine diesel, the function analysis system technique graphical method (FAST) is used to analyze the function of the marine diesel to screen out 16 key components which are the research elements of Value Engineer. The comprehensivefunction proportion analysis and cost analysis method are used to analyze their value and determine the components which need to be improved. At last, this paper gives out the enforceable improving scheme.
A low-profile circularly polarized microstrip antenna using elliptical electromagnetic band gap structure

Abstract This study investigates a low-profile circularly polarized (CP) antenna using coplanar waveguide feeding. Rectangular-shaped slots and an inverted L-shaped slit are entrenched into the ground plane to enhance the impedance bandwidth of the antenna. Furthermore, the antenna is implemented with six elliptical electromagnetic band gap structures on its substrate to enhance the −10 dB return loss bandwidth and also to generate CP waves. The experimental and theoretical results closely match each other and indicate that a simple and compact design antenna with dimensions of 0. 317λ0 × 0. 317λ0 × 0. 023λ0(λ0 is the operating wavelength at 4.74 GHz in free space) achieves 36.9% (3.91–5.68 GHz) of the −10 dB return loss bandwidth and 9.98% (4.09–4.52 GHz) of the 3-dB axial ratio bandwidth, thus making it a favorable entrant for radio altimeter and wireless avionics infra-communication systems.
Entrepreneurs’ self-perceived social status and firms’ philanthropy: evidence from Chinese private firms

ABSTRACT Executives’ status is increasingly recognized as an important factor in firms’ decision-making, while the way executives’ perception of their status influences firms’ strategy is underexplored. Building on insights from both upper echelons and psychological studies, this study investigates the effect of entrepreneurs’ self-perceived social status on firms’ philanthropy. Using a sample of Chinese private firms, we find that entrepreneurs’ self-perceived social status positively affects firms’ donations by drawing their attention to the benefits of philanthropy and enhancing their altruism values. However, such relationships are weakened for entrepreneurs who know about awards related to CSR and firms that join a business association that values CSR; this shows that external information about the value of CSR reduces the effect of entrepreneurs’ self-perceived social status. Our findings highlight the importance of executives’ self-perceived social status, offering important implications for both CSR and upper echelons research.
Monilogging for executable domain-specific languages

Runtime monitoring and logging are fundamental techniques for analyzing and supervising the behavior of computer programs. However, supporting these techniques for a given language induces significant development costs that can hold language engineers back from providing adequate logging and monitoring tooling for new domain-specific modeling languages. Moreover, runtime monitoring and logging are generally considered as two different techniques: they are thus implemented separately which makes users prone to overlooking their potentially beneficial mutual interactions. We propose a language-agnostic, unifying framework for runtime monitoring and logging and demonstrate how it can be used to define loggers, runtime monitors and combinations of the two, aka. moniloggers. We provide an implementation of the framework that can be used with Java-based executable languages, and evaluate it on 2 implementations of the NabLab interpreter, leveraging in turn the instrumentation facilities offered by Truffle, and those offered by AspectJ.
Fabrication of 1-Mbit DRAMs By Using X-Ray Lithography

Functional 1-Mbit DRAM devices were fabricated by using x-ray lithography. An x-ray stepper ( Nikon SX-5) which has a high brightness x-ray tube (10 kW) with a Pd rotating target was used for the fabrication of the devices. The alignment system is based upon the use of a linear diffraction grating as an alignment target. The mask-to-wafer alignment is performed by detecting the first-order diffraction beam of incident laser beams from the grating alignment target. The wafer diameter is 150 mm, the mask diameter is 75 mm, and the exposure field size is 25x25 mm2. A W-Ti alloy absorber was used as an x-ray mask absorber. Since W-Ti absorber films can be controlled to have an internal stress of less than 1 x 108 dyne/cm2, the mask distortion was less than 0.1 μm for the 15x15 mm2 field including two 1-Mbit DRAM chips. The x-ray lithography was applied to the contact process by using a novolak-based positive resist XPB. The XPB resist has high sensitivity, high resolution capability, and high dry etch resistance. The alignment error was less than 0.15μm in 3σ. A 1-Mbit DRAM with a bit yield of 99.5% was obtained. It was thus demonstrated that x-ray lithography technology has the potential for use in VLSI fabrication.
Extensions and performance/robustness tradeoffs of the EWMA run-to-run controller by using the internal model control structure

We consider the run-to-run (RtR) correction of input recipes for semiconductor manufacturing processes using measurement information from previous runs. A RtR control algorithm that has been experimentally tested by industry and academia is the EWMA (exponentially weighted moving average) RtR controller. In this paper we provide extensions to this algorithm to address some of its drawbacks and also provide a rigorous theoretical analysis of its properties based on discrete control theory. By formulating the RtR control problem in the internal model control (IMC) structure used in feedback process control, we are able to extend the algorithm to completely eliminate offsets due to unmodeled process drifts, which is a common problem in semiconductor manufacturing. We also develop conditions for robustness with respect to modeling error and measurement delays. Tradeoffs between robustness guarantees and fast RtR response as well as handling of measurement noise are developed and presented in the form of plots that can be used for tuning the parameters of the RtR-IMC controller to accomplish the objectives set by the process engineer. The results are illustrated through several simulations including control of film deposition uniformity in an epitaxial reactor and tungsten deposition rate in a tungsten CVD reactor.
Proactive language control during bilingual sentence production

Aims and objectives/purpose/research questions: While evidence for proactive language control processes has been found during single word production, very little and conflicting evidence has been observed for such control processes during sentence production. So, the main goal of this study was to investigate whether proactive language control can occur during sentence production. Design/methodology/approach: To investigate proactive language control during sentence production, we relied on a description task in single and mixed language blocks. Data and analysis: Mixing costs and the reversed language dominance effect of language intrusions and filled pauses were used to examine proactive language control. Findings/conclusions: Evidence for proactive language control during sentence production came from the mixing cost effect observed with both language intrusions and filled pauses. Whereas no reversed language dominance effect was observed in mixed language blocks, a significant difference in language pattern was observed between single and mixed language blocks, indicating that proactive language control of the first language might be implemented in mixed language blocks during sentence production. Originality: Unlike the vast majority of studies investigating language control, this study relied on sentence production instead of single word production. Moreover, to the best of our knowledge, this is the first study to examine filled pauses to gain insight into language control. Significance/implications: These data indicate that proactive language control can be implemented during bilingual sentence production.
MAC protocols and fairness control in WDM multirings with tunable transmitters and fixed receivers

The paper illustrates novel proposals for medium access control protocols in all-optical packet networks based on WDM multichannel ring topologies where nodes are equipped with one fixed-wavelength receiver and one wavelength-tunable transmitter. Such networks provide separate slotted channels for disjoint subsets of destination nodes. Three access protocols based on local status information are described. A channel inspection capability is assumed to be available for the implementation of the access protocols. Global fairness control algorithms derived from those adopted in the Metaring high-speed metropolitan area network are also proposed. Access delays and throughputs are taken as performance Indices for a simulation-based comparison of the proposed protocols, in the case of a 16-node multiring with either balanced or unbalanced traffic. Simulation results show that the throughput limitations and the fairness problems inherent in the network topology can be overcome with relatively simple protocols.
Robotics: Modelling, Planning and Control

The classic text on robot manipulators now covers visual control, motion planning and mobile robots too! Robotics provides the basic know-how on the foundations of robotics: modelling, planning and control. The text develops around a core of consistent and rigorous formalism with fundamental and technological material giving rise naturally and with gradually increasing difficulty to more advanced considerations. The theory of manipulator structures presented in the early part of the book encompasses: the fundamentals: kinematics, statics and trajectory planning; and the technology of actuators, sensors and control units. Subsequently, more advanced instruction is given in: dynamics and motion control of robot manipulators; mobile robots; motion planning; and interaction with the environment using exteroceptive sensory data (force and vision). Appendices ensure that students will have access to a consistent level of background in basic areas such as rigid-body mechanics, feedback control, and others. Problems are raised and the proper tools established to find engineering-oriented solutions rather than to focus on abstruse theoretical methodology. To impart practical skill, more than 60 examples and case studies are carefully worked out and interwoven through the text, with frequent resort to simulation. In addition, nearly 150 end-of-chapter problems are proposed, and the book is accompanied by a solutions manual (downloadable from www.springer.com/978-1-84628-641-4) containing the MATLAB code for computer problems; this is available free of charge to those adopting Robotics as a textbook for courses. This text is suitable for use in senior undergraduate and graduate courses in automation and computer, electrical, electronic and mechanical engineering courses with strong robotics content.
Clinical utility of hand held, non invasive transcutaneous bilirubinometer in neonatal jaundice: a prospective observational study

Background: Neonatal Jaundice is the most common morbidity in the first week of life, occurring in 60% of term and 80% of preterm newborn. However, visual inspection, being subjective, usually inaccurate and unreliable and will result in a number of unnecessary blood sampling. Taking all these in to considerations, transcutaneous bilirubinometer (TCB) may provide a solution which is an objective, noninvasive, fast and painless method of bilirubin estimation.Methods: Transcutaneous bilirubinometer levels were measured at forehead and sternum and blood samples for TSB were collected by venepuncture within 30 minutes and sent to biochemistry lab. After getting serum bilirubin reports, TCB and TSB values were compared by using Bhutani’s hour specific nomogram. Results: The correlation between serum bilirubin and transcutaneous bilirubin measured at forehead and sternum is very good at serum bilirubin <15 mg/dl, r value (Karl Pearson’s Correlation co-efficient) is 0.93 and 0.94 respectively.Conclusions: The findings of the present study indicate that the TCB is a reliable screening tool for hyperbilirubinemia in newborns >35 weeks of gestation, especially with bilirubin levels ≤15 mg/dl in 2-7 days of life. TCB can be a viable option for universal screening. Incorporating the use of TCB devices in clinical practice, can reduce the need for blood sampling for the management of neonatal jaundice.
Model predictive control with constraints for a nonlinear adaptive cruise control vehicle model in transition manoeuvres

A vehicle following control law, based on the model predictive control method, to perform transition manoeuvres (TMs) for a nonlinear adaptive cruise control (ACC) vehicle is presented in this paper. The TM controller ultimately establishes a steady-state following distance behind a preceding vehicle to avoid collision, keeping account of acceleration limits, safe distance, and state constraints. The vehicle dynamics model is for continuous-time domain and captures the real dynamics of the sub-vehicle models for steady-state and transient operations. The ACC vehicle can execute the TM successfully and achieves a steady-state in the presence of complex dynamics within the constraint boundaries.
Impact of Shading of a Silvopastoral System on Microclimate and Botanical Composition of Polyphytic Pasture: A Preliminary Study in the Subtropics

The silvopasture system is an integrated system which has been widespread in tropical and sub-tropical climates. However, there is a lack of detailed studies regarding agroecological silvopasture systems. This study assessed whether the different levels of shading in an agroecological silvopastoral system influences the microclimate and botanical composition of polyphytic pasture. We used eight paddocks composed of a silvopastoral system in a subtropical climate, with different tree species arranged in simple lines with polyphytic pasture. In each paddock, we established three levels of visual shading (under the canopy, intermediate and full sun). The following microclimatic variables were recorded monthly during the daytime: illuminance, air temperature, air relative humidity, wind speed, and surface soil temperature. The samples of forages were separated into grasses, legumes and spontaneous, then fractionated into leaves, stems, and senescent material. We observed lower values of illuminance and surface soil temperature under the canopy, with differences between full sun and under the canopy at noon. Regarding the forage, the percentage of legumes was higher in full sun, and spontaneous species and leaves had high proportions under the canopy. Based on the results, the agroecological silvopastoral system changed the microclimatic characteristics and altered the plant composition of polyphytic pasture.
Relationship between quality‐management systems and organizational innovations

The purpose of this study is to ascertain whether there is any correlation between the implementation of quality‐management systems (QMSs) in manufacturing firms and the use of certain organizational innovations in those firms. A conceptual model of the relationships among the constructs of “organizational innovations” and “level of quality management” is proposed and tested. The study finds a correlation between the level of quality management in an organization and the implementation of procedural organizational innovations. Because the study is pioneering and exploratory in nature, the analysis is confined to the use of a limited number of organizational innovations in Spanish manufacturing firms. The findings will assist managers to make appropriate strategic decisions when implementing QMSs. © 2010 Wiley Periodicals, Inc.
APPLICATION OF HIGH-LOW BED CFB COMBUSTION TECHNOLOGY TO OIL SHALE COMBUSTION

A 75 t/h pulverized coal-fired boiler has been successfully revamped to a 65 t/h oil shale-fired circulating fluidized bed (CFB) boiler employed by the high-low bed CFB combustion technology. The 65 t/h boiler was installed in Suixi cement factory, Guangdong province, China, and put into operation in 2006. The designed fuel is oil shale and comes from Maoming deposit, Guangdong province. The average low heating value is about 4.1 MJ/kg. Boiler performance tests showed that the main technical and economic parameters meet the designed requirements, which can provide a theoretical and technical basis for the design and operation of a large-scale oil shale-fired circulating fluidized bed boiler.
Innovative approaches to the development of a new sour milk product

The topic provides an analysis of the current approach to healthy nutrition and represents a new functional fermented milk drink based on buttermilk containing natural prebiotics - a biologically valuable complex Spirulina platensis. The main tasks of the industry as a holistic system for the management and production of food ingredients and products are outlined. The work highlights the requirements for the quality and context of the functional product manufacture, the main criteria for the consumer choice, and positioning of products in the healthy lifestyle system. The topic covers the most common pro- and prebiotics, including strains. The unique food green microalgae Spirulina platensis as a source of biologically valuable components is proposed for industrial application. A technique for the production of the fermented milk drink based on buttermilk and spirulina as prebiotic was developed and scientifically substantiated. The protein contained in buttermilk is characterized by high nutritional value, exhibits functional properties and can significantly affect the quality of the drink. To confirm this, the possibility of using buttermilk with different protein content from 2.9 to 3.2 to improve the structure of the clot in the composition of the drink and the content of spirulina from 10 to 20% was studied. As single criteria for optimizing the prescription composition of the drink at the different protein content of buttermilk used indicators of product quality - acidity, degree of syneresis, organoleptic parameters. The optimal values of the individual criteria are obtained in different ranges of protein content 3 times 1-2-2; sample 2-3.0; sample 3-3.2%, which allows you to get recommendations for the formulation of a new type of drink.
Reusing software to produce broadband services

Software reusability is a technique for improving productivity and quality, which is finally finding general acceptance. A model for software reuse is described as part of a software development life cycle. The approach takes into account software development with reuse of existing components as well as production of assets for future reuse. A successful experience using this framework to produce broadband services is also presented.
Knowledge‐Elicitation Study in Construction Scheduling Domain

Little discussion has occurred in journal circles regarding knowledge‐elicitation experiences during the development of civil engineering expert systems. This paper focuses on that subject by discussing CRITEX, a system written for the Corps of Engineers with the purpose of critiquing construction schedules. Its perspective is that of an owner's reviewing initial and in‐progress schedules. The following knowledge‐elicitation techniques are used: (1) Published material review; (2) structured interview; (3) observation of tasks and behavior with limited information. Comments are made about using these three approaches, as well as four other available approaches. Use of multiple techniques results in richer systems. The key in selecting the correct combination of knowledge‐elicitation methods starts with looking at the problem‐domain characteristics and system‐developer resources. A novel aspect of this investigation is the knowledge engineering experiment that was conducted. The purpose of this test was to .
Miniaturisation of planar microwave circuits by using resonant-type left-handed transmission lines

It is demonstrated that planar microwave circuits and components such as impedance inverters or power dividers, among others, can be compacted by using artificial left-handed transmission lines in their designs. Key to this size reduction is the possibility to control the electrical characteristics of these lines (namely electrical length and image impedance) over wide margins by means of a single cell structure. It consists of a microstrip line section with a series capacitive gap etched in the conductor strip and loaded with a complementary split rings resonator etched in the ground plane. A recently reported model of the artificial line is used as a first step in the design of the desired devices. To demonstrate the viability of the approach, several prototype device examples are provided, that is a 90° impedance inverter and several power dividers with different topologies. A 50% size reduction (as compared to conventional devices) has been achieved by implementing the devices in conventional low loss microwave substrates, but further levels of miniaturisation can be obtained if the devices are fabricated on advanced technologies such as low temperature co-fired ceramic or multi chip module-deposited, among others.
Characterization, Prediction, and Improvement of Stretched Flat Hexagonal Gossamer Membrane Dynamic Response

1 Abstract This paper provides initial results of a research program to characterize, predict, and improve the dynamic response of gossamer structures. The work described in this paper focused on nominally flat membranes. Flat membranes are of interest as they form the key functional part of many proposed gossamer structure architectures such as sun shields, solar sails, solar cell arrays, fresnel concentrators, and optical flats. Effort was divided into several areas. First discussed is the experimental characterization of the complex stiffness of typical membrane structure materials. Next, the experimental characterization of the response of basic stretched membrane components to disturbances is reviewed. These results were then matched numerically using UAI NASTRAN. Finally, the ability to add damping to such structures through passive approaches is demonstrated. Key findings of interest are that 1) typical gossamer structure materials were experimentally observed to have Young's modulus values that were slightly frequency dependent and structural loss characteristics were more highly frequency dependent over the measurement range, 2) experimentally determined dynamics of flat stretched membranes were confirmed numerically despite the presence of local wrinkling, and 3) the potential to augment inherent damping with passive damping treatments was demonstrated.
