Realist Constructivism: An Introduction

This chapter looks at the general relationship between realism and constructivism in international relations theory. It introduces both approaches, and argues that the distinctions often drawn between them, such as those between materialism and idealism and between logics of consequences and appropriateness, do not in fact make them incompatible. It suggests that areas of fruitful overlap between realism and constructivism are to be found in the study of the institution of the state and of individual agency in foreign policy. The chapter also lays out the plan of the book, and briefly introduces the other chapters.
Robust Reliable Control for a Class of Uncertain Time-Delay Switched Fuzzy Systems Based on Observers Switching

It is presented a model of uncertain time-delay switched fuzzy systems, which each subsystem of switched system is an uncertain time-delay fuzzy system. The robust reliable control problem is studied by multi-Lyapunov functions. When the actuators are serious failure – the residual part of actuators can not make original system stability, using switching technique depend on the states of observers, robust fuzzy reliable controller is built to ensure the relevant closed-loop system is asymptotic stability. The results for example are used to illustrate the feasibility and the effectiveness of the method.
Analysis and implementation of a series-parallel resonant converter with magamp postregulators

A half-bridge series-parallel resonant converter (SPRC) with and without post-regulators is investigated in discontinuous conduction mode operation, A comprehensive analysis of the SPRC is presented. The SPRC is superior to the pure series and parallel converters, having the desirable characteristics of each, without the disadvantages. The SPRC with a magnetic amplifier (magamp)which blocks the rising edge of the secondary voltage, is analysed. Modified topological modes and steady-state analysis are proposed. Experimental results show that the SPRC with postregulators has good cross-regulation. A 100 kHz SPRC with and without magamp postregulators is designed and tested.
An Ensemble Learning Short-Term Traffic Flow Forecasting with Transient Traffic Regimes

Short-term traffic flow forecasting has a rich and substantive research history. For layered hybrid forecasting approaches, traffic flow series are classified into distinct regimes based on characteristics of different traffic conditions so that regime-specific forecasting models can be trained to adequately and consistently approximate dynamic traffic dynamic behaviors. However, traffic regimes are inherently changing and transient, making it a challenging task to perform regime-specific forecasting. In this paper, an ensemble learning approach is proposed and regime-based forecasting models are developed to address the nonlinearity and non-stationarity of traffic flow data. Case study results demonstrate that the proposed approach can effectively account for transient regimes and produce accurate online short-term traffic forecasts.
Study on Multi-DOF Ultrasonic Actuator for Laparoscopic Instrument

In surgical robots, compact manipulators with multi-degree-of-freedom (DOF) are essential owing to a small work volume in the patient body. Conventional single-DOF actuators such as electromagnetic motors require a multiple number of actuators to generate multi-DOF motion, which in turn results in bulky mechanism combined with transmission device. Our previous work has developed a compact ultrasonic motor capable of generating a multi-DOF rotation of a spherical rotor utilizing three natural vibration modes of a bar-shaped stator. The present study designs and builds a novel multi-DOF master-slave system for laparoscopic surgical procedures, using a single ultrasonic actuator. The system consists of surgical forceps on multi-DOF wrist with joystick controller. Experimental results have confirmed high responsiveness and precise position control of the master-slave system.
Performance evaluation of a simple and general space vector pulse-width modulation-based M-level inverter including over-modulation operation

This study presents a simple and a generalised space vector pulse-width modulation scheme for a neutral point clamped multi-level inverter as well as cascaded inverter of any level. This modulation algorithm implements the online generation of desired switching states and their sequences through generalised expressions without any predetermined stored data in a memory look-up table. The proposed algorithm also incorporates the concept of reference vector and on-time modification combined during the over-modulation region for any level of inverter. Performance of the proposed modulation algorithm is tested experimentally through a digital signal processor-based controller for a five-level cascaded inverter with very low execution time that does not depend much on the level of inverter. The simulation waveform and the harmonic analysis of the voltage at different modulation index are presented and these are verified with the experimental results.
A Framework for Computer Supported Cooperative Work

A conceptual framework for computer supported cooperative work is presented. A distinction is made between the context of the work, the use situation (which is a part of the context), and the computer system. The context of the work refers to the totality of the work: the kind of work, its organisation, etc. Cooperative work is seen as an aspect of the context of the work. The use situation is more delimited, it is the work situation(s) where the computer system actually is used. The use relation is defined to be the relation between the context of the work, including the use situation, and the computer system. Computer supported cooperative work is defined as a quality of this relation. This quality is obtained when the computer system is used in such a way that the cooperative aspects of the work are supported. This definition denies that computer supported cooperative work should be seen as a property of the context of the work or of the computer system alone. The use relation can be of many kinds. Three use relations: medium, shared material, and tool are of special interest to computer supported cooperative world. Two applications of the framework are pointed at. One is its use in analysis when computer support for cooperative work is to be developed. The other is its application as a relevance criterion for research in computer supported cooperative work.
Związek między członkostwem w organizacjach a przynależnością klasową w perspektywie międzynarodowej

Currently, there is only a limited amount of research on the propensity of people in different classes to participate in civic organization. Using data from the European Social Survey 2002 the author explores the patterns and intensity of relations between civic participation and social class in 19 countries. He examines class differences in the recruitment to four basic types of the associational membership on the assumption that there may be various forms of social exclusion and inequality. This relationship is compared across various types of welfare regime, in line with the suggestion that there is signiﬁcant variation in social involvement across welfare regimes. This analysis shows that, indeed, civic associations could be differentiated according to their class composition. In line with expectations class differences are ordered from the most to the least advantaged groups with respect to their socio-cultural position. In all countries, representatives of the service class are most likely to take part in civic organizations. They are followed by lower non-manual categories, and owners, and most disengaged from formal participation are working class people and agricultural categories. This suggests that civic organizations appear to be preservers of advantaged categories (i.e. higher professionals and managers) while categories located near the bottom of socio-economic ladder are deprived of access to them.
MRAS for Speed Sensorless Direct Torque Control of a PMSM Drive Based on PI Fuzzy Logic and Stator Resistance Estimator

In this paper, a sensorless Direct Torque control (DTC) for Permanent Magnet Synchronous Motor (PMSM) drive based on Adaptive Model Reference (MRAS) algorithm and PI with adapted gains fuzzy logic (FL) are presented. The MRAS is utilized to estimate speed and stator resistance and compensate the effects of parameter variation on (stator resistance variation introduce errors flux and torque estimation and affect the performance of DTC). In other hand, speed regulation by PI with two adaptive FLC is investigated and compared with classical PI controller. Simulation results are presented and show the effectiveness of the proposed method.
Dynamic sensing optimization strategy for mobile nodes deployment in wireless sensor networks

Sensor nodes deployment problem is one of the fundamental issues in wireless sensor networks (WSNs) which should consider a tradeoff among several metrics, such as coverage area, reliability, accuracy, lifetime etc. The mobile sensor nodes which can relocate themselves can be used to optimize the nodes deployment under various kinds of situations. Because coverage area is hard to be calculated by analytical method, an areas division method is introduced to evaluate the coverage area metric for simplifying calculation. Then we introduce a practically feasible combined metric which refers to coverage area, reliability, accuracy and lifetime, which uses areas division, detecting reliability, Mahalanobis distance and energy entropy as metric functions. Here, nodes deployment is considered as an optimization problem. Particle swarm optimization (PSO) algorithm, which has a series of advantages, such as, high-speed regional convergence, efficient global searching ability, and so on, is suitable for solving multi-dimension function optimization in continuous space. So we adopt PSO for nodes deployment optimization where the combined metric is considered as fitness function. Because the combined metric is multiform and changeable in PSO, we can adopt different combined metrics for different applications, while other strategies just consider the coverage area in nodes deployment. The experimental results verify that the PSO based mobile nodes deployment strategy has good performance in quickness, which can improve the capabilities of WSNs and dynamically adjust the deployment according to the changes of situation, especially when some areas need multiple-node-measurement.
NONLINEAR ANALYSIS OF PRESTRESSED CONCRETE BOX GIRDER BRIDGES UNDER FLEXURE

One-seventh scale direct models of single-cell and two-cell prestressed concrete box girder bridges, tested to destruction at McGill University, are analyzed by the nonlinear finite element technique. The nonlinear program NONLACS, utilized in the analysis, is described in detail together with the material models employed. The objective of the current study is to demonstrate the capabilities of the finite element program NONLACS in predicting the ultimate strength and complete response of prestressed concrete box girder bridges at all stages of loading up to the ultimate load. The load–deflection curves, concrete and steel stresses, and deflected shapes of the bridges at different load levels are compared with the corresponding experimental data. The results verify the applicability of the nonlinear finite element method as an economical and expedient alternative, in some cases, to expensive experimental work aimed at the investigation of the complete response of complex structures to applied loads.

Miniaturized optical and microwave receiver module using double conductor CPWs for active phased array antennas

Miniaturized optical and microwave receiver module using DCCPWs (double conductor coplanar waveguides) has been developed for active phased array antennas. This antenna requires flexible, lightweight, and low loss feeders to element radiators. This module comprised of a microstrip-to-slot transition, two chips of low-noise MMIC amplifiers, and a laser diode module is fabricated on an ultrathin package with 10/spl times/30/spl times/1.5 mm3 in size and 2 g in weight to achieve an ultra-thin structure of active phased array antenna panels. To provide low noise and ultra-thin size, DCCPWs are employed in the design of input matching circuit of low-noise MMIC amplifiers. In addition, the ultra-thin structure is attributed to the design of laser diode modules using silicon V-groove technology and fiber alignment method.
Convenience and Frequency of Recycling

This research investigated the effect of convenience on recycling frequency and variables that could be used as indicators in the prediction of recycling behavior as a basis for including textiles in curbside recycling programs. Results clearly indicated that access to curbside recycling significantly affected the amount and variety of materials recycled. Logistic regression results pointed to the variables of access, shopping behaviors, age, family size, and income as significant predictors of recycling activity, regardless of how recycling activity was defined. Despite reduced access to textile recycling opportunities, textile recycling overall was still high. The authors concluded that households with high recycling activity could be identified and targeted for extending curbside recycling programs to include textiles. To continue to reduce the amount of solid waste that is diverted to landfills, curbside recycling programs must be extended to include a greater diversity of postconsumer waste products such as textiles and apparel.
An analysis of coplanar waveguides with finite conductor thickness-computation and measurement of characteristic impedance

Computer analysis is performed for coplanar waveguides with finite conductor thickness. Such line parameters as the characteristic impedance and effective filling fraction are obtained. Experimental verification is given for the characteristic impedance. Assuming that the line cross section is approximately symmetrical, Laplace's equation is solved by a successive over-relaxation method for one quarter of the cross section. The characteristic impedance obtained by this approximate method is compared with that obtained by analysis of one half of the cross section with rigorous symmetry and the difference is found to be less than 0.27%. Experimental verification of the characteristic impedance is conducted by correcting the discontinuity between the measurement setup and the line to be measured. The difference between the analytical and experimental results is less than 10%. Approximate analysis by the present method is thus sufficiently accurate. The size of the storage locations in the computer is reduced and the processing time is shortened.
The Application of the Farm Accounting Based on Sufficiency Economy Philosophy (SEP) in Order to Achieve Sustainable Development

The study of social and environmental accounting reveals a lot of critical global problems and need to developing an alternative approach to face economic and social development. This study aimed to review the spiritual-socio-cultural-economy values and criticize the application of Farm accounting cost. The concept reference of the study is based on Sufficiency Economy Philosophy paradigm combined with Laku Prihatin paradigm of Javanese culture, the main principles to create Sufficiency Economy Philosophy are Moderation, Reasonableness and Self Immunity. The study method used is critical ethnomethodology with a qualitative approach. The research site is in the Badegan area, Ponorogo Regency. The study results showed that 1) The concept of financing accounting in the Farm accounting does not represent the level of welfare of farmers, the welfare of farmers not oriented to material and (economic) growth but substance equitable dynamic values by a just relationship with God, society and the natural environment, 2) The concept of financing accounting should be in accordance with spiritual-socio-cultural values, by applying the cost of production with a Sufficiency Economy Philosophy and Net Farm Income (NFI) that is in favor of the farmers, 3) The principle of a Sufficiency Economy Philosophy provides good results for society in physical, social and economic aspects.
The analysis of static random access memory stability under the influence of statistical variability and bias temperature instability-induced ageing

In this paper, the stability of static random access memory (SRAM) under the influence of statistical variability and bias temperature instability (BTI) induced ageing is investigated by statistical simulations. Effectively infinite and accurate compact models are successfully generated using ModelGenTM technology to prevent subsampling problem and ensure the statistical SRAM investigation, which successfully present device simulation results for circuits. The impact of transistor’s statistical variability on the SRAM stability is evaluated by SRAM static noise margin (SNM) sensitivity test. Three BTI induced ageing patterns of the SRAM cell are analysed at different ageing levels. The distribution, increase and decrease percentage of SNM is calculated at statistical level to show the combined effects of transistors’ variability with different ageing pattern.
Photonic crystal waveguide directional coupler based on adiabatic coupling

An optimal design of Photonic crystal waveguide (PCW) directional coupler (DC) with adiabatic coupling is presented in this paper. Planar wave expand (PWE) method and FDTD method are used to analyze and optimize PCW-DC. It is shown that use this PCW-DC can achieve efficient transmission ratio in cross state, bar state and power division state at different coupling length. The simulation results show that the coupling ratio can be higher than 90% in some selective wavelength in these states. With the help of adiabatic coupling and bent PCW, the coupling coefficient of two parallel SMFs whose distance from each other at standard interval of 125μm can be higher than 90%. This also suggests that this device can realize a very efficient add/drop filter device which can be used in WDM system.
Application of wavelets in Doppler ultrasound

Provides an introduction into wavelets and illustrates their application with two examples. The wavelet transform provides the analyst with a scaleable time‐frequency representation of the signal, which may uncover details not evidenced by conventional signal processing techniques. The signals used in this paper are Doppler ultrasound recordings of blood flow velocity taken from the internal carotid artery and the femoral artery. Shows how wavelets can be used as an alternative signal processing tool to the short time Fourier transform for the extraction of the time‐frequency distribution of Doppler ultrasound signals. Implements wavelet‐based adaptive filtering for the extraction of maximum blood velocity envelopes in the post processing of Doppler signals.
Active integrated antenna using a T‐shaped microstrip coupled‐patch antenna

In this paper, an active integrated antenna using a T‐shaped microstrip coupled patch antenna, which acts as DC isolation in the RF path, is proposed. The designed feedback‐antenna oscillator has stable oscillation and a clear spectrum at the frequency of 5.813 GHz, which is only a 0.2% deviation from the design frequency. The measured EIRP is 19.2 mW, and the cross‐polarization levels are at least −13 dB lower than the co‐polarization ones for all directions. © 2005 Wiley Periodicals, Inc.

A novel rotor configuration for brushless doubly-fed induction generators

Brushless Doubly-Fed Induction Generator has attractive features to be the first choice in next generation of wind generators. However, its efficiency and power-to-weight ratio are slightly lower in comparison to induction machine with the same rating. Considerable part of these imperfections arises from the rotor design, which produces magnetic field with considerable undesirable spatial harmonics. This paper proposes a novel rotor configuration to reduce spatial harmonic distortion of air-gap magnetic field as well as improving some drawbacks of the conventional structure, including unequal magnitudes of rotor bar currents, teeth saturation at low average air gap magnetic fields, high core loss and inefficient magnetic material utilization. The rotor loops are connected in series in the new scheme rather than nested arrangement of the conventional design. Furthermore, the Imperialist Competitive Algorithm is used for optimising the conductor distributions in order to improve spatial distribution of the rotor magneto-motive force. The rotor current is evaluated in each iterative step using electric equivalent circuit. The analytical procedure of determining the circuit parameters is modified for the case of series loops. Effectiveness of the novel configuration is verified by comparing the results of optimised and conventional designs in several experimental and simulation studies.
Facilitating ambidexterity with HR practices - a case study of an automotive supplier

In dynamic environments organisations are challenged to simultaneously explore new capabilities and to exploit existing ones; a capability that has been named 'ambidexterity'. Research identified that ambidexterity can be achieved through different means (e.g., structural ambidexterity, contextual ambidexterity). Ambidexterity, however, is always based on individual competencies of organisational members. Yet, the link between organisational means aimed at achieving ambidexterity and the individual competencies of the employees have remained imprecise. In order to tackle this link, we conducted a case study at a technological leader in the automotive supplier industry. We analyse how ambidexterity can be combined with issues of psychological management research, transformational leadership style, competency management and new theories on work performance. Thereby, we shed light on the link between individual competencies and human resource (HR) practices aimed at achieving organisational ambidexterity. Our research allows inferring recommendations for academics and practitioners how to better manage ambidexterity.
