The Research on Cloud Manufacturing Service Discovery Strategy Based on Mapping Reuse

In view of the heterogeneous gulf between service providers and resource service demanders in cloud manufacturing platform, an ontology mapping reusing algorithm was proposed to improve the performance of service discovery. Firstly, a semantic bipartite graph between the concepts profile was built to get the similarity of neighboring concepts from the best match of the bipartite graph. Then inspired by the similarity transmission between neighboring concepts, whether the new mapping should be established was decided by the existing mapping and the similar degree between the neighboring concepts. Finally, I testified the algorithm by an experiment.
Design Methodology for Offshore Platform Conductors

The problem of analyzing and designing that segment of an offshore platform conductor located between the mudline and deck is examined. A new set of efficient and easy-to-use conductor design equations has been developed on the basis of the fundamental principle that internal casing string loads do not produce any buckling tendencies. An example conductor design has been included which illustrates that the method, when compared with the typical conductor design approach, is extremely efficient and cost effective, capable of producing several million dollars of cost savings for a major platform project. A new method of designing offshore conductors has been developed. The method properly distinguishes between the nature of internal casing string loads and loads produced by external effects such as dead load caused by the wellhead and BOP stack. Implementation of the method is easily accomplished by use of a new set of extended interaction equations, which have been validated through numerical simulation. Application of the method to an example conductor design problem has been demonstrated. A comparison of the new design solution with the traditional design approach indicates that substantial cost savings can be achieved amounting to several million dollars for a major platform project. The methodmore » is based on the widely used AISC stability criterion, which has been developed for nontubular structural members. Application of the method to the design of tubular conductors should provide conservative results. Future work is suggested that would synthesize conductor design criteria utilizing the increasing volume of information becoming available on tubular member behavior. Development of a probability-based load and resistance factor design approach to conductor design is also suggested. « less
The Design of Wireless Sensor Network System Based on ZigBee Technology for Greenhouse

Wireless sensor network is a new research field. It can be used in some special situation for signal collection, processing and transmitting. Zigbee is a new Wireless sensor network technology characteristic of less distance and low speed. It is a new wireless network protocol stack of IEEE 802.15. 4. Lately traditional system to collects parameters for Greenhouse is widely used in agriculture. The traditional system adopts wired way wiring, which makes the system complex and expensive. Generally modern Greenhouse has hundreds of square meters and they may plant variety of plants depending on different seasons. So we need to adjust the sensors which collect parameters for Greenhouse to a better place to work more efficient. Adopting wireless way wiring is convenient and economical. This paper developed a wireless sensor network system based on ZigBee technology for greenhouse. It offers flexibility and mobility to save cost and energy spent on wiring. The framework hardware and software structure, related programming are also discussed in this paper. Comparing the system which uses ZigBee technology with traditional wired network system for greenhouse, it has advantage of low cost.low power and wider coverage. Additionally it complies with IEEE802.15. 4 protocol, which makes it convenient to communicate with other products that comply with the protocol too.
Global Oceans

Trends in the 0–700-m layer all agree within their 5%–95% confidence intervals. However, as noted in previous reports, the trends in the 700–2000-m layer, which is quite sparsely sampled prior to the start of the Argo era (circa 2005), do not all overlap within uncertainties. Different methods for dealing with under-sampled regions likely cause this disagreement. Using repeat hydrographic section data collected from 1981 to 2021 to update the estimate of Purkey and Johnson (2010) for 2000–6000 m, the linear trend is 0.07 (±0.03) W m −2 from September 1992 to January 2012 (these dates are global average times of first and last sampling of the sections). Summing the three layers (despite their slightly different time periods as given above), the full-depth ocean heat gain rate ranges from 0.64 to 0.80 W m −2 applied to Earth’s entire surface.
Vamos passear na floresta! O conforto térmico em fragmentos florestais urbanos

This study investigated the role of urban forest fragments in thermal comfort. For that purpose, five different locations in the city of Campinas (Brazil) were monitored during the summer, autumn and winter of 2009. Microclimatic data were obtained with the use of a portable weather station that measured air temperature, air humidity, radiation, wind speed and globe temperature. In addition, structured interviews and field observations were carried out to evaluate the thermal comfort conditions and the occupants’ perceptions of their environment. The PMV and PET indices were calculated by the RayMan 1.2 software and compared with the actual votes obtained through the interviews. The results indicate that urban forest fragments improve thermal comfort. The percentage of subjects reported as thermally neutral varied between indices: 72.4% were found comfortable, 63.3% were in the PET limit of 18-23 o C, and 39,8% were in the PMV range of -0.5 to +0.5. Occupants perceived those places as comfortable, linking this to nature, but they also observed some problems regarding conservation and occupation. The specific forest microclimate, fresh air, and the perception of clean air were also cited by the population and can be linked to environmental comfort.
Influence of Heavy Data Transmission Losses on Spectra of Signals

Measurements of machine vibrations are often influenced by heavy data losses during wireless transmission of signals, which arise because of electromagnetic interference of electric motors. In this paper, authors present an analytic calculation of distortions introduced in spectra of harmonic signals by heavy data transmission losses, which are characterized by the loss ratio and frequency of losses. The results may be used to reduce errors that arise during spectral analysis of signals in conditions of heavy spectral losses.
Detection of Buried FRP Composite Pipes Using Ground Penetrating Radar

Millions of miles of pipelines are used in the United States to transport natural gas and petroleum products. The traditional metallic pipelines undergo significant amount of corrosion related degradation in the field environment, which have led to numerous accidents. This research proposes innovative Fibre Reinforced Polymer (FRP) composite pipes for replacing degraded metallic pipes and for new pipeline construction. The FRP composite pipes are lighter, non-corrosive and have a long service life. However, they pose a challenge for subsurface detection and mapping since the traditional techniques used by construction crews to detect buried metallic pipes do not work for non-metallic composite pipes. This research investigates the use of Ground Penetrating Radar (GPR) Nondestructive Testing (NDT) technique in conjunction with innovative strategies to make buried FRP composite pipes detectable, which is crucial for the field implementation of the new generation of pipelines.
DESIGN FEATURES OF A PARALLEL TESTING PLATFORM FOR SIMULATING KINEMATIC CHARACTERISTICS OF HIP JOINT

To simulate the movement of a human during daily activities, such as walking, running, squatting, and kneeling, a novel parallel hip joint simulator whose key movement component is a 3SPS + 1PS parallel manipulator with four degrees of freedom (DOF) was proposed. SPS denotes the spherical-prismatic-spherical leg, and PS denotes the prismatic-spherical leg where only the prismatic joint is actuated and hence underlined. Firstly, the formulae for solving the inverse kinematics of the 3SPS + 1PS parallel manipulator were derived based on the unit quaternion method. Then, the parallel hip joint simulator was designed and finally developed by means of constructing the mechanical module, control module, hydraulic loading module, and data transmission module. In addition, three linear actuators are driven by the scheduled inverse displacement trajectories to enable the moving platform to output rotations about the Z-, Y-, and X-axes for representing flexion/extension, abduction/adduction, and external/internal rotations of the human hip joint. Simultaneously, the hydraulic loading module represents the dynamic loading as described by ISO 14242 Part-1 acting on the hip joint during the kinematic experiment. The kinematic experiment and dynamic loading experiment show that the fitting curves of the experimental results are consistent with the designed movement and loading trajectories. All these illustrate that the developed 3SPS + 1PS parallel hip joint simulator with effective design of all modules can substantially represent the designed movement and loading trajectories. The developed hip joint simulator can provide more reliable tribology test data for artificial prosthesis of hip joint.
Statistical Energy Analysis of Wind Noise in High-Speed Train Cab

Statistical energy analysis(SEA) method has many advantages in analysis of high frequency, high modal density and complex dynamic systems. Dividing high-speed train cab into a series of sub-systems, the SEA model of high-speed train cab was established. The factors affecting the cab noise, such as modal density, damping loss factors, coupling loss factors, were gotten by theoretical analysis combined with experiments. Using large eddy simulation method, the fluctuation pressures from train head surface were calculated. Using fluctuation pressure as excitation source, wind noise spectra and power flow of sub-systems in cab were obtained, which provided the basis for the control of high-speed train cab noise.
Emergence of a New Policy for Asbestos: A Result of the World Trade Center Tragedy

Modern day risks from asbestos, especially in environmental settings, have been questioned. The concerns associated with stringent regulation of asbestos are mostly no longer voiced in regulatory communities. As a result of the World Trade Center (WTC) event in 2001, issues relating to the actual risks of asbestos in building materials have re-surfaced. Regulatory agencies, through their policy statements, have downplayed the risks associated with the WTC event of asbestos in debris and dust which covered the surrounding area. These statements now question past practices and requirements associated with asbestos as mandated by these same agencies. It is suggested that such statements by asbestos regulatory agencies will reduce and lower the current regulatory requirements, and change the direction of regulatory policy. This paper discusses risks from asbestos and the possible future direction of regulatory standards for these minerals in the United States. Future risks from ‘‘hazardous’’ materials, it is suggested, should be based on actual scientific facts, with less influence from social and political factors.
Some Magic Tees with 2 to 3 Octaves Bandwidth

Techniques have been developed which extend the frequency range of ring magic tees to 7:1 or more. Experimental 250 to 1000 MHz ring magic tees have been built with 0.6 db insertion loss (above the 3 db power split), 0.2 db amplitude balance, 2/spl deg/ phase balance, and a 1.5:1 maximum VSWR over the 2-octave frequency range. An experimental 300 to 1800 MHz ring magic tee has been built with the performance shown in Figure 5. Figure 1 shows schematically the basic ring magic tee, and a typical curve of VSWR versus electrical length. The four transmission lines are nominally 70.7 ohms characteristic impedance for a maximally flat design. If the line impedances are made 65 ohms, then the basic design has an equal ripple 1.18:1 VSWR bandwidth of one octave.
A Tale of Two States: The Hanger and Niland Reports

Abstract The paper compares and contrasts the Hanger and Niland reports—two major reports on industrial relations reform at a State level. It locates these reports within a political framework. The Hanger Report, relating to Queensland, was cautious and endorsed the centralized arbitration system. The Niland Report (relating to New South Wales), supported a decentralized, enterprise-based system. Both reports emphasize procedures at the expense of considering the content of industrial relations.
Identifying the challenging factors in the transition from colleges of engineering to employment

The transition from university to a career in engineering is a challenging process. This study examined the perceptions of engineering graduates regarding the difficulties they encountered in their transition from the university to the workplace. Lebanese practising engineers (n=217), living around the world, were surveyed to identify their current employment situations and their attitudes toward their academic preparation. Factor analysis revealed three main challenges facing engineering graduates: communication; responsibility; self-confidence. Seventeen interviews were conducted to gather information on ways to facilitate this transition. Comments reflected the need for better collaboration between engineering schools and engineering firms. The results will provide insight for engineering colleges, faculty members and administrators into the challenges faced by graduates and their aspirations for a smoother transition into employment.

A non-redundant transition clock chain is proposed and applied to differential edge-triggered flip-flops. PSPICE simulation shows that compared to a recently published design the proposed circuit can save power when switching activity of the input signal <0.65. Power reduction can be as high as 86% when the input is idle.
Silicon sensors for catheters and guide wires

One area that can make use of the miniature size of present day micro electromechanical systems (MEMS) is that of the medical field of minimally invasive interventions. These procedures, used for both diagnosis and treatment, use catheters that are advanced through the blood vessels deep into the body, without the need for surgery. However, once inside the body, the doctor performing the procedure is completely reliant on the information the catheter(s) can provide in addition to the projection imaging of a fluoroscope. A good range of sensors for catheters is required for a proper diagnosis. To this end, miniature sensors are being developed to be fitted to catheters and guide wires. As the accurate positioning of these instruments is problematic, it is necessary to combine several sensors on the same guide wire or catheter to measure several parameters in the same location. This however, brings many special problems to the design of the sensors, such as small size, low power consumption, bio-compatibility of materials, robust design for patient safety, a limited number of connections, packaging, etc. This paper will go into both the advantages and design problems of micromachined sensors and actuators in catheters and guide wires. As an example, a multi parameter blood sensor, measuring flow velocity, pressure and oxygen saturation, will be discussed.
An Emulative Precast Segmental Concrete Bridge Column for Seismic Regions

This work proposes a new precast segmental concrete bridge column. The lower region of the column is built using cast-in-place (CIP) construction. The height of the CIP region and level of post-tensioning force in the precast region are selected such that the ultimate condition of the column under seismic loading is governed by a conventional plastic hinge mechanism in the CIP region. A tall column was constructed and subjected to cyclic loading. Test results indicate that the column has excellent ductility and energy dissipation. A pushover analytical method was proposed and applied to the proposed column. This method captured joint opening through the joint rotation length and the amount of curvature exceeding the cracking curvature. Analytical results agree well with test results in predicting the envelope of hysteretic behavior, the increase in axial force in the precast region, and the contribution of precast and CIP regions to column displacement.

Over-Reliance Issues with Task Guidance Systems

Over-reliance occurs when the human responsible for completing a task allows a task aid to have too much authority. Over-reliance, long recognized as a problem with automation and decision aiding systems, now appears to also be an issue for task guidance systems. Task guidance systems are computer-based systems that guide a user through a task. A recent investigation of how the capabilities of a wearable computer may be used to provide task guidance in mobile environments demonstrated the possibility for over-reliance in these systems. Specifically, this investigation examined a wearable computer inspection aid for preflight inspection of general aviation aircraft. Pilots using the wearable computer inspection system were less thorough in their inspection than the pilots completing the inspection from memory. Deficiencies in the procedures used on the task guidance systems made it clear that the pilots with the wearable computer inspection aid were over-relying on its information. Details of this investigation and goals for future investigations into an interface design process to mitigate over-reliance in task guidance systems are discussed in this paper.
A Systemic Functional Grammar-Based Critical Discourse Analysis of Jamaica Kincaid’s Lucy

The present paper investigates the grammatical choices made by Jamaica Kincaid in her work Lucy. It analyzes how the selected structure contributes to the realization of particular beliefs such as gender inequality, using the Systemic Functional Grammar (SFG) approach (Halliday 1973, 1985, 1994; Halliday and Hasan 1989; Halliday and Matthiessen 2004). In particular, the study examines the participants’ roles and the processes types assigned to them with reference to the transitivity system. The data of the present study are collected from the first three chapters of Lucy. The corpus belongs to seven males and eleven female characters who were directly involved in all the actions in the text. A total of 325 sentences were extracted. They were quantitatively and qualitatively analyzed. The results of the study revealed the writer’s subvert of traditional gender stereotypes through displaying women as effectual dynamic actors and assertive sayers. In addition, all female characters were shown as the main participants of the other minor processes, in the sense that they were the behavers and sensers in both behavioral and mental clauses. Keywords: critical discourse analysis, gender inequality, systemic functional grammar, transitivity system.
RSS-Based Indoor Localization System with Single Base Station

: The paper proposes an Indoor Localization System (ILS) which uses only one fixed Base Station (BS) with simple non-reconfigurable antennas. The proposed algorithm measures Received Signal Strength (RSS) and maps it to the location in the room by estimating signal strength of a direct line of sight (LOS) signal and signal of the first order reflection from the wall. The algorithm is evaluated through both simulations and empirical measurements in a furnished open space office, sampling 21 different locations in the room. It is demonstrated the system can identify user’s real-time location with a maximum estimation error below 0.7 m for 80% confidence Cumu-lative Distribution Function (CDF) user level, demonstrating the ability to accurately estimate the receiver’s location within the room. The system is intended as a cost-efficient indoor localization technique, offering simplicity and easy integration with existing wireless communication systems. Unlike comparable single base station localization techniques, the proposed system does not require beam scanning, offering stable communication capacity while performing the localization process.
Effects of Seed Rates and Herbicides Application on Weed Management and Productivity of Wheat (Triticum aestivum L.) at Holeta Ethiopia

Wheat is one of the most important food security crops which is cultivated from small to large scale farms in Ethiopia. However, its productivity has been limited due to various abiotic and biotic factors including weeds. The aim of the study was to investigate the effects of seed rates and post emergence herbicides application on weed management and productivity of wheat. Factorial combinations of three levels of seed rates (100,150 and 200 kg ha -1 )and four types of herbicides (Agro 2,4-D 720 g/L 1lt ha -1 ,Pallas 45 OD 0.5lt ha -1 ,Derby 175 SC 100ml ha -1 and Lancolet 450 WG 33 gm ha -1 )along with control (a weedy check) were laid out in RCBD with three replications. A total of identified 12 weed species were recorded (86 % broad and 14 % grass weeds). Results also revealed that significant effects of seed rate by herbicide interaction for all the traits studied. The minimum weed densities (2.7 m -2 ) at 45 days after planting , dry biomass of grass weeds (33.33 kg ha -1 ) and the highest weed control efficiency (81.22%) were recorded from the interaction effects of 150 seed rate with Pallas 45 OD while the minimum dry biomass of broad leaf weeds (53.33 kg ha -1 ) was recorded at 200 kg ha -1 seed rate with Lancolet 450 Wattable Granule (WG). The highest number of productive tillers(133.33 m -2 ),seeds per spike(76.48), thousand grain weight (44.36 g),grain yield (4516.42 kg ha -1 )and biological yield(13100 kg ha -1 ) were recorded from the combination of 150 kg ha -1 seed rate with Pallas 45 OD while the lowest values were observed from the weedy check . Grain yield had strong positive correlations with each of the yield components, however it was negatively correlated with dry weed biomass. Based on partial budget analysis, the maximum net benefit was obtained from the interaction of 150 kg ha -1 seed rate with Pallas 45 OD but higher number of marginal rate of return was calculated from 150 kg ha -1 seed rate with 2,4-D . It was also observed that, the combined use of seed rate 150 kg ha -1 with Pallas 45 OD effectively managed weeds, economical and gave maximum yields, which could be recommended for the test environment. Since the experiment was conducted in one location and for a single season, it should be repeated over seasons or multi locations for best recommendation.
