The Effect of Team Identification, Knowledge Integration on Project Management Performance

This study examines the relationships among team identification, knowledge integration and project management performance. Using data from 22 high-tech companies with 115 employees in China, this study finds that team identification is positively related to knowledge integration but not related to project management performance. In addition, knowledge integration plays an intermediary role on team identification and project management performance, and has direct positive impact on project management performance.
Acquisition of Throwing Skill Involving Projectiles of Varying Weights

Abstract This investigation was conducted in order to determine if there were differences in the degree to which accuracy in throwing with the nonpreferred hand was developed when practice with projectiles of varying weights was used during the learning period. The effects of transfer of learning from the throwing of a ball of one weight to performance with a ball of another weight was also studied. The result indicated that practice with a light ball was as effective as practice with a heavier ball in developing skill to throw a heavier ball. Practice with the heavier ball when transferred to the lighter ball did not demonstrate a corresponding effect.
Fuzzy-logic-based VAr stabiliser for power system control

The paper presents a new approach to the design of a robust controller for the auxiliary control loop of a static VAr system using both fuzzy logic and variable structure system (VSS) concepts. Also, the design of a simple fuzzy controller using the least number of rules for stabilisation of a synchronous generator connected to a large power system is presented. The performances of fuzzy, variable structure fuzzy and VSS stabilisers are compared with a conventional stabiliser for a variety of transient disturbances, highlighting the effectiveness of these stabilisers in providing significant damping to the system oscillations.

These can be of great useful for image restoration of many blurring circumstances such as camera and printing images.
Wave Equalization - A New Image Enhancement Method for Gray Image Binarization under Uneven Illumination

The gray image can be viewed as a 3D terrain consisting of intensity waves. The Wave Equalization introduced in the paper is to weaken the influence of uneven illumination on the gray image binarization. The 2D wave is decomposed into several 1D waves corresponding to different directions for 1D equalization. Then PCA algorithm is used to compress all 1D results to the final image with uniform illumination. The extensive experiments in the paper had proved that our method has excellent performance and adaptability for various uneven illumination environments.
Anti- Ehrlichia properties of the dichloromethane extract of Ageratum conyzoides

Ehrlichia canis is an intracellular bacterium that infects hematopoietic cells. It is the causative agent of canine monocytic ehrlichiosis (CME). The disease may be acute, subclinical, or chronic, and is treated with tetracyclines including doxycycline. However, this class of tetracyclines may cause several side effects due to prolonged treatment. Bacterial resistance to antimicrobials has been extensively reported. The present study aimed to assess the anti- Ehrlichia activity of the dichloromethane extract (DCM) of Ageratum conyzoides L. on Ehrlichia- infected DH82 cells. For this purpose, the DCM extract of A. conyzoides collected in the municipality of São Luís, State of Maranhão (MA), northeast Brazil, was obtained from the aerial parts of the plant by exhaustive percolation in H 2 O- CH 2 Cl 2 (2:8) and subsequent extraction of the chemical compound. The chemical composition of these samples was investigated. The anti- Ehrlichia properties of A. conyzoides were confirmed in Ehrlichia- infected DH82 cells at a concentration of 200 μg. mL -1 of its DCM extract. The results of the treatments were evaluated at 18h and 36h after the insertion of the treatments evaluated with A. conyzoides.Based on the results of the chemical analysis of the samples, we may attribute these antirickettsial properties to the compounds from the lignan family that are found in this medicinal plant .
Die großen Buddha‐Statuen von Bamiyan ‐ Zustand, Stabilität und Möglichkeiten der Rekonstruktion

Im März 2001 wurden die großen Buddha‐Statuen im Tal von Bamiyan, Afghanistan, von den Taliban zerstört. Die Rettung der noch erhaltenen Überreste ist seither das Ziel internationaler Bemühungen. Der Zustand der beiden großen Statuen sowie die Stabilität der Felsnischen, in denen sie sich befanden, wurden im vergangenen Jahr von einer Expertengruppe der ICOMOS (International Council on Monuments and Sites) untersucht. Die durch Sprengungen herabgefallenen originalen Statuenbruchstücke müssen danach dringend vor Verwitterungen geschützt werden.
Dynamic modeling of ergometer and on-water rowing

Indoor rowing, which began as a means of keeping fit when conditions do not allow training on the water, has become a sport in its own right, and indoor rowers are found in gyms and fitness clubs worldwide and performed by many athletes for cross‐training and conditioning. A mathematical model is presented and is used to analyze the dynamics of a rower in a single scull on the water and to compare these with the dynamics of the ergometer system. The results show that while the ergometer provides an acceptable simulation of the entire system dynamics, it cannot simulate the movement of the boat during the recovery, the sensitivity of the boat to movement of the body during the recovery when the blades are out of the water. The model shows that the hull speed of the boat, and hence the drag on the boat, is highest during the recovery, and hence underlines the importance of technique during the recovery to the overall speed of the boat on the water. It can be concluded that the ergometer is a useful training.
A Dynamic Estimator for Tracking the State of a Power System

The problem of real-time estimation of the state of a power system is treated from the point of view of the theory of least-squares estimation (Kalman-Bucy filtering). Since under normal operating conditions, the power system behaves in a quasi- static manner, a simple model for the time behavior of the power system is derived. This model, together with the real-time measurement system, enables the design of a tracking state-estimator algorithm. The proposed algorithm has several advantages over the previously suggested static estimator algorithm in regard to its computational aspects, real-time implementation, and the accuracy of the estimated state.
Temperature Effect on Creep Behavior of CFST Arch Bridges

Because concrete-filled steel-tube (CFST) arch bridges usually reside in areas with strong temperature effects, which influence concrete creep behavior considerably, this paper aims to present an approach to evaluate the temperature influence on the creep behavior of CFST arch bridges, which has not been reported until now. Based on the microprestress-solidification theory for concrete creep, the age-adjusted effective modulus method and a proposed temperature estimation method were integrated into a finite-element model to calculate the creep behavior of a half-through long-span CFST arch bridge. The comparison between the predictions and measurements validated the efficiency of this approach and also demonstrated the necessity of considering temperature history in the creep-effect analysis of CFST arch bridges. The numerical method proposed in this paper provides a practical way to evaluate the temperature-involved creep effects on CFST structures.
Augmenting Social Media Research with Q Methodology: Some
 Guiding Principles

This paper proposes that social media studies could be complemented with Q methodology when a topic that plays out in social media is complex, controversial or sensitive to allow for deep‑seated, integrated online and off‑line perspectives. Although the Fourth Industrial Revolution brought researchers more opportunities and advantages to study topics that were previously inaccessible, using technologies for research does not come without challenges. This is especially the case with social media studies comprising large datasets and where it is not always possible to identify fake profiles, bots, spam or manipulated information without having access to advanced data analysis software. Another point is that views expressed in social media do not always represent offline perspectives. However, while Q methodology has, over the years, adapted its techniques to accommodate new technologies, more can be done to embrace a web 2.0 environment. Why and how social media studies could be augmented with Q methodology to reveal individuals’ perspectives and attitudes about topics will be examined and potential difficulties will be highlighted. Not yet a mainstream method, Q methodology combines the strengths of two robust qualitative and quantitative methods sequentially to reveal and isolate the subjective perspectives of groups of participants. This methodology could, therefore, be useful when a social media study puts forward novel ideas and findings that should be supported by offline views. In this regard, the paper provides some guidelines by referring to the five phases of a Q study and describing how a social media study could not only benefit from but also apply Q methodology to augment results. Supplementing social media research with Q methodology could be empowering and provide opportunities for further research and debate.

The Influence of 40 Hz Electromagnetic Wave Induce Phase-Synchronization on Brain

Auditory phase-synchronization near 40Hz is reportedly related to sensory stimulation. This study applied the phase synchrony analysis and Bi-coherence analyses to analyze the electroencephalographic measurements. Four experimental stages were conducted with 34 healthy high school students to collect the data: (A) resting with eyes closed, (B) listening to the classical music, (C) resting with eyes closed, and (D) listening to popular music. The result shows that the whole brain phase-synchronization occurs at 40Hz and lasts about 400 ms, which is quite different from the estimated 40Hz phase-coupling lasting about 20–25 ms in previous studies and seems to play an important role in inducing auditory attention loss. Additionally, the result also shows that hypersynchronous states may affect perceptual processing. This study develops an original nonlinear time serial analytical approach and suggests that 40Hz phase-synchronization might be an important indicator in perceptual process.
Ensuring the quality, reliability and precision of measurement processes through traceability

Inadequate measurement capability can place a heavy burden of implicit costs on manufacturers – even drive them out of business. It can have serious consequences for stakeholders in industry, commerce or science. High‐technology manufacturing must ensure a high level of precision in measurements, often to as much as a millionth of an inch. In seeking such high levels of precision, measurement laboratories often use traceability as a key precision criterion. Two comprehensive sets of measurements made over time by high‐precision laboratories on gauge blocks are used to explore the scope of traceability in ensuring high‐precision measurements. Significant differences were found between the high‐precision primary laboratories traceable to the National Institute of Standards and Technology in the USA. Explores general implications of such between‐laboratory differences and makes recommendations for secondary laboratories and stakeholders in dimensional metrology seeking to ensure a high level of precision in .
From HRM practices to the practice of HRM: setting a research agenda

Purpose – The purpose of this paper is to develop an “HRM-as-practice” research agenda. The authors suggest that the HRM-performance literature would benefit from an actor-centric approach and a focus on activities, and that the HR roles research needs to shift its attention toward a more dynamic perspective of HR work and link this further to performance. Design/methodology/approach – The paper first provides an overview of strategy-as-practice (SAP) literature, and then review how extant HRM literature deals with three core notions of SAP: practices, praxis and practitioners. Based on this, the paper outlines an “HRM-as-practice” research agenda. Findings – Focussing on the intersections between praxis, practitioners and practice, the paper suggests that an “HRM-as-practice” approach can give new insights into first, how people-related decisions are made, implemented and enacted in organizations; second, how employees and other HRM stakeholders interpret and engage with HRM; third, how HR actors become .

Design and Implement of Intelligent Monitoring System Driven by Ultrasonic Motor

A visual tracking system based on ultrasonic motors is designed in view of shortcoming of traditional video surveillance system, which has a large volume, complicated structure. The pan-tilt can rotate in horizontal and vertical directions by using two ultrasonic motors served as the driving units. The image from video camera is processed and the target is identified and real-time tracked by rotating the pan-tilt which is controlled by ultrasonic motor. Compared with electromagnetic motor, the ultrasonic motor has advantages of high torque at low speed, quick response, high precision and self-locked, which makes the structure simpler and control more convenient. Experimental results show that the system can be stably tracking the selected target with fast response speed and relatively high tracking accuracy.
Real-Time Water Allocation for Irrigation

Throughout the world the importance of water management is becoming more important as the demand for water increases. As one of the major uses of water, irrigation could benefit from improved management practices. The establishment of a Water Operations Centre in Indonesia has seen the development of a real-time water-allocation model for a complex irrigation system covering 60 000 ha. The model uses linear programming (an optimization technique) to determine the best way in which to allocate limited water supplies while keeping crop yield losses to a minimum.
The culinary creative process of Michelin Star chefs

ABSTRACT Fascination for modern forms of creativity in the kitchen constitutes a differentiating factor in restaurants and for chefs in a particular destination. It finds its maximum expression in fine dining restaurants and more specifically in restaurants with Michelin Star chefs. This study explores the culinary creativity of Michelin Star chefs, with the assumption that the cuisine prepared by them can be considered art, or at least, that it has an artistic component which makes each restaurant unique. This research analyses creativity in haute cuisine through an exploratory qualitative approach that included in-depth personal structured interviews with eighteen Michelin Star chefs in Portugal. The research method based on oral narratives was chosen to evaluate emotions, to explore desires and to understand chefs’ creative processes, from the initial idea to the conception of the dish. The study shows that although there is a consensus regarding the different forms of inspiration and generation of ideas, there are also many different perspectives on the creative process, which differentiate culinary artisans.
Experimental Research on Cavitation Characteristics of a Novel Hybrid Journal Bearing

Under high and super high speed, the oil film of a journal bearing is easy to crack and then becomes cavitation. The existence of cavitation has a great effect on the work performance of the bearing. The cavitation mechanism of a spiral oil wedge journal bearing was investigated on the experimental rig. The effects of rotating speed and supply pressure on the cavitation shape of oil film and the number of cavitation strip in the rupture zone were analyzed. The results show that the cavitation shape of oil film is a long strip. The number of cavitation strip increases when supply pressure has been improved, and the location of oil outlet must be designed optimally.
Analysis of waveguide discontinuities using a hybrid method combining the Helmholtz weak form and mode expansion

A new approach for the analysis of waveguide multiports discontinuities is presented in this paper. This approach is a combined method of the mode‐expansion method and finite‐element method, which is based on the weak form of the Helmholtz equation. We use a mode expansion technique other than PML to truncate the computing space of finite element. Multiport structures such as H‐Plane forked T‐junction, waveguide loaded with two dielectric posts, and E‐plane filter are studied as examples. The calculated results of these structures are shown and compared, respectively, to those in references. Good agreement between them is observed. © 2004 Wiley Periodicals, Inc.

Salt Effects in Plastered and Unplastered Outdoors Brick Masonry: Quantitative Laser Monitoring of Surface Decay Evolution

In masonry materials, the superficial decay is a widespread problem. Aggressive environmental agents such as moisture and salts trigger the damage by propagating through the material capillary pores. Although several studies have been carried out on salt crystallization and their damaging effects, additional research effort is required to better investigate this phenomenon on real cases and real weathering conditions. To this purpose, testing and monitoring tools capable of following degradation process since the early beginning are necessary. Repeated visual inspections are commonly used to monitor the superficial decay, but this technique is subjective and thus not capable of providing any quantitative information. In this work, an experimental campaign, carried out in Bologna, Italy, is presented. A two-header brick wall, one main face unplastered and one plastered, was stored outdoors and exposed to weathering over two summers. Before the start of the second aging season, moisture and salt capillary rise was simulated by low-concentrated sodium chloride solution (0.1% -wt). The aim was to favor solution evaporation and salt crystallization and to provoke material damage. The degradation process was monitored based on a contactless, rapid and accurate image diagnostic technique. In particular, high-resolution laser scanning by triangulation technique was adopted. Three-dimensional data acquisition was repeated at the end of both seasons. The proposed procedure successfully extracted quantitative information approximately areas of material spalling and detachment even in the initial phases of decay.
A Current-Mode Common-Mode Feedback Circuit (CMFB) with Rail-to-Rail Operation

Abstract This paper presents a current-mode common-mode feedback (CMFB) circuit with rail-to-rail operation. The CMFB is a stand-alone circuit, which can be connected to any low voltage transconductor without changing or upsetting the existing circuit. The proposed CMFB employs current mirrors, operating as common-mode detector and current amplifier to enhance the loop gain of the CMFB. The circuit employs positive feedback to enhance the output impedance and gain. The circuit has been designed using a 0.18 μm CMOS technology under 1V supply and analyzed using HSPICE with BSIM3V3 device models. A pseudo-differential amplifier using two common sources and the proposed CMFB shows rail to rail output swing (± 0.7 V) with low common-mode gain (–36 dB) and power dissipation of 390 μW.
International Conference on High Performance Cutting , HPC 2014 Development of a chip pulling system for efficient turning

Combined with the chip guiding, this paper presents a new “assisted turning method” where the cut chip is pulled using an external pulling device to improve the performance of turning process. In the proposed method, straight unbroken chip is generated by utilizing special tool tips and guided through a guide tunnel for automated chip pulling. The first prototype of chip pulling device is designed that can pull the guided straight chip continuously as the turning operation is carried on. Design of the chip pulling system, proposed pulling device and its automatic control are presented in this research. A brief insight on the effect of chip pulling to the turning process is discussed by inspecting fundamental process parameters. Experimental results show that by pulling the chip in a controlled manner, process can be improved dramatically. Cutting forces and temperature are effectively reduced in actual “chip pulling turning”. © 2014 The Authors. Published by Elsevier B.V.
