Making use of historical case material: the problems of looking back and the implications for service development in relation to research and evaluation activities

Abstract This methodological paper details the process of embarking on a follow-up study of young people with sexual behaviour problems who were known to services in the 1990s and who are now young adults in their 20s or early 30s. In the context of the importance of such follow-up work, the overall aim and objectives of the funded research project are specified and the challenges presented in setting up research partnerships with service sites, including the negotiation of access and ethical approval, are the subject of overview and reflection. The practicalities of beginning the fieldwork which comprised an initial analysis of historical case material held in the research sites are then detailed and the solutions to the problems encountered are explained. The paper concludes by identifying the kinds of questions services and researchers need to consider when wanting to engender or enhance a research culture which is facilitative of this kind of outcome research. These relate to the resources necessary to support a research culture, the requirements of data protection and ethical approval processes, obtaining service user consent to participate in future research, secure but accessible storage of records, staff development and researchers’ obligations to minimise disruption to already hard-pressed services.
The Proto-Fuse project: methods to boost creativity for architects

Human civilization can be ameliorated by human creativity. Innovation and progress of human civilization result from a change in our thinking patterns, thus, potentially transforming the present into a creative future. Accentuating the role of creativity in design even more than other disciplines pushes one to underpin the understanding of creativity as a key role player in architecture. Furthermore, by identifying the basic principles of our ingenuity/creativity, researchers might be able to enhance this ability in the future. The digital era allows for a new domain of architectural experience. It is assumed that new designs in virtual environments can be created that go beyond the mere accommodation of literal functions, and affect human experiences. This paper presents the role of a method developed by the authors: ‘Proto-Fuse’, experimented with, as an artwork for the survey of cognitive perception of humans, specifically targeting enhancement of spatial creativity. The logic behind this method is based on two psychological concepts: 1 – conceptual blending, 2 – tolerance of ambiguity. Two experimental projects were conducted for exploring the Proto Fuse method: (a) “unconventional virtual environments (UVEs)” to improve conceptual blending and (b) “Extracting local distance” to enhance tolerance of ambiguity. The paper concludes with an implementation scenario of the Proto-Fuse method in the pedagogy of architecture and elaborates on the results of the projects and analysis of the feedbacks received during the project session.
Development and testing of a magnetorheological actuator for an assistive knee brace

This paper proposes an assistive knee brace that is aimed to provide assistance to old or disabled people. A magnetorheological (MR) actuator is developed to be used in assistive knee braces to provide controllable torque. The MR actuator consists of a DC motor and an MR brake/clutch. When active torque is needed, the DC motor works and the MR actuator functions as a clutch to transfer the torque generated by the motor to the leg; when passive torque is desired, the DC motor is turned off and the MR actuator functions as a brake to provide controllable passive torque. The prototype of this MR actuator is fabricated and experiments are carried out to investigate the characteristics of the MR actuator. The results show that the MR actuator is able to provide sufficient torque needed for normal human activities. Adaptive control is proposed for controlling the MR actuator. Experiments of the MR actuator under control are performed to study the torque tracking ability of the system.
Broadband low-crosspolarisation horn

The authors describe preliminary theoretical results for a new type of feed which offers the potential for low crosspolarisation over a broadband. The canonical structure is a corrugated waveguide partially filled with a dielectric rod. The new structure radiates like a corrugated horn when the corrugation depth is near lambda /4 and like a dielectric loaded smooth wall horn when the corrugation depth is near lambda /2.
Amplified spontaneous emission in semiconductor laser amplifiers: validity of the transmission-line laser model

Previously, the transmission line laser model (TLLM) has been used to predict the pulse response of semiconductor laser amplifiers. This paper shows that it can also be used to find the magnitude and spectral properties of internally amplified spontaneous emission noise in travelling-wave, Fabry-Perot and DFB laser amplifiers. >
Numerical Simulation on Convective Heat Transfer in Microchannels of Two-Stage Y-Branch Bifurcation Structures

Convective heat transfer in microchannels of two-stage Y-branch bifurcation structures at different inlet velocities and branch angles were simulated, and the temperature, static pressure drop as well as the relationship between Reynolds Number (Re) and Nusselt Number (Nu) of fluid were compared and analyzed. The results indicate that the flow in microchannels with 30° branch angle has the minimum pressure drop for the velocities from 0.5 m/s to 2.5 m/s, while it comes at 60° for the velocities from 2.5 m/s to 3.5 m/s. It can also be found that the laminar-turbulent transition comes in advance compared with the common round channels. The critical Reynolds Number is found to be in 1997-2224, which is smaller than the known value of 2300. The Nu increases with increasing Re with a same trend for the different branch angles.
Self-sensing High Speed Controller for Piezoelectric Actuator

This study proposes an effective scheme for high speed positioning control of a piezoelectric actuator. The proposed approach is based on the combination of a feedforward branch and a proportional integral derivative (PID) feedback controller. The feedforward branch consists of an inverse model of the actuator that includes hysteresis compensation, inverse mechanical transfer function, and electrical losses compensation. In order to avoid using a bulky and costly displacement sensor, a detection model has been developed to compute the displacement of the piezoelectric actuator as a function of the current. This approach has been compared with a regular PID feedback control scheme, and with a feedforward/feedback controller using a sensor. Experiments have been carried out for a 2ms pulse excitation of the actuator. It is shown that the proposed approach allows to combine feedforward advantages (quickness and hysteresis compensation) and feedback advantages (static error and creep cancellation). Moreover, it is shown that the detection model allows to smartly avoid using any mechanical sensor.
MODULAR MULTI-SENSORY FLUIDIC ACTUATOR WITH PLEATED ROTARY ELASTIC CHAMBERS

Abstract This paper describes the concept and development of a new fluidic rotary actuator with natural compliance, intended for industrial automation devices and robots working in human environment. The actuator comprises few fully integrated modules with matched mechanical, electrical and software interfaces. The core element of the actuator is newly developed fluidic motor with pleated rotary elastic chambers, which replace rigid chambers of the conventional vane motor. Compact mechatronic module in hydraulic realization is presented, while considering pneumatic realization also. Due to its modular design and inherent compliance, the actuator is particularly suitable for building complex kinematic structures, as for example soft robotic arms.
Simple printed monopole slot antenna for penta‐band wireless wide area network operation in the mobile handset

A simple printed monopole slot antenna for penta‐band wireless wide area network operation (824–960/1710–2170 MHz) in the mobile handset is presented.The monopole slot has a length of 50 mm only and is embedded close to the bottom edge of the system ground plane of the handset with a small distance of 11 mm. By adding a small‐size C‐shaped strip connected orthogonal to the bottom edge of the system ground plane, good excitation of the monopole slot antenna at its fundamental (0.25 wavelength) and higher‐order resonant modes can be obtained. The excited resonant modes form two wide operating bands to cover the GSM850/900 operation (824–960 MHz) and GSM1800/1900/UMTS operation (1710–2170 MHz). Detailed operating principle and radiation characteristics including the specific absorption rate results of the proposed monopole slot antenna are described. Measured results of the fabricated antenna are also presented. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett 53:1399–1404, 2011; View this article online at wileyonlinelibrary.com.

How teams in networked organisations develop collaborative capability: processes, critical incidents and success factors

In this article, we present a study on collaborative capability of teams in three networked organisations in Austria and Switzerland. So far, collaborative capability has mostly been conceptualised on an organisational or individual level as a set of attributes that actors employ to collaborate successfully. We found that this view of collaborative capability needs to be enlarged. Collaborative capability of teams is characterised by at least two components: an attribute-based perspective that focuses on capabilities of single actors or organisations, and a perspective on group dynamics which describes how teams successfully develop collaborative capability. We examined collaborative work processes and task requirements and the way critical incidents in different project stages influenced the development of collaboration. We discuss our findings with regard to the different organisational settings of the networks analysed and the current literature on collaborative capability and networked organisations. Moreover, we identify six critical success factors for collaboration and discuss the role of network management in co-innovation.
A novel PWM control for a bi-directional full-bridge DC–DC converter with smooth conversion mode transitions

A novel CMOS integrated pulse-width modulation (PWM) control circuit allowing smooth transitions between conversion modes in full-bridge based bi-directional DC–DC converters operating at high switching frequencies is presented. The novel PWM control circuit is able to drive full-bridge based DC–DC converters performing step-down (i.e. buck) and step-up (i.e. boost) voltage conversion in both directions, thus allowing charging and discharging of the batteries in mobile systems. It provides smooth transitions between buck, buck-boost and boost modes. Additionally, the novel PWM control loop circuit uses a symmetrical triangular carrier, which overcomes the necessity of using an output phasing circuit previously required in PWM controllers based on sawtooth oscillators. The novel PWM control also enables to build bi-directional DC–DC converters operating at high switching frequencies (i.e. up to 10 MHz and above). Finally, the proposed PWM control circuit also allows the use of an average lossless inductor-current sensor for sensing the average load current even at very high switching frequencies. In this article, the proposed PWM control circuit is modelled and the integrated CMOS schematic is given. The corresponding theory is analysed and presented in detail. The circuit simulations realised in the Cadence Spectre software with a commercially available 0.18 µm mixed-signal CMOS technology from UMC are shown. The PWM control circuit was implemented in a monolithic integrated bi-directional CMOS DC–DC converter ASIC prototype. The fabricated prototype was tested experimentally and has shown performances in accordance with the theory.
Information Technology Business Value Model for Engineering and Construction Industry

The idea that the deployment and strategic utilization of information technology (IT) resources as factors of production can be used by organisations to improve performances has been around for many decades. The contributions of the IT resources in improving organisation’s performances give rise to what is termed IT business value (ITBV). There have been varieties of conceptualizations and attempts to measure the ITBV by different researchers. However, most of these attempts to quantify ITBV have led to inconsistencies and paradoxes. Furthermore, a major part of the literature in the area continues to be anecdotal and primarily descriptive. Therefore, there is little evidence of an accepted theoretical framework for applying the ideas and there is even less in the way of empirical evidence concerning the validity and utility of these concepts. The research adopts multi-theoretical concepts of process-based, resource-based and microeconomics views as the theoretical framework in order to mitigate the absence of structured theoretical framework in the previous studies. A non parametric approach of Data Envelopment Analysis was used for empirical testing of the model developed. The findings present an empirically tested model for benchmarking IT-induced productivity in construction industry. Also the outcome of the research establishes that IT provides business value in undertaking the engineering and construction business processes, which leads to significant impact on the organisations performances in the areas of project delivery, customer relationship and overall profit growth. For practical purposes, the model could be used to provide support to managers in decision making on IT investments, utilization of the IT resources and how combination of strategic IT resources with other organizational resources could in increase efficiency in delivering project value chains.
In-Process Detection of Weld Defects Using Laser-Based Ultrasonic Lamb Waves

Laser-based ultrasonic (LBU) measurement shows great promise for on-line monitoring of weld quality in tailor-welded blanks. Tailor-welded blanks are steel blanks made from plates of differing thickness and/or properties butt-welded together; they are used in automobile manufacturing to produce body, frame, and closure panels. LBU uses a pulsed laser to generate the ultrasound and a continuous wave (CW) laser interferometer to detect the ultrasound at the point of interrogation to perform ultrasonic inspection. LBU enables in-process measurements since there is no sensor contact or near-contact with the workpiece. The authors have used laser-generated plate (Lamb) waves to propagate from one plate into the weld nugget as a means of detecting defects. This report recounts an investigation of a number of inspection architectures based on processing of signals from selected plate waves, which are either reflected from or transmitted through the weld zone. Bayesian parameter estimation and wavelet analysis (both continuous and discrete) have shown that the LBU time-series signal is readily separable into components that provide distinguishing features, which describe weld quality. The authors anticipate that, in an on-line industrial application, these measurements can be implemented just downstream from the weld cell. Then the weld quality data can be fed back to control critical weld parameters or alert the operator of a problem requiring maintenance. Internal weld defects and deviations from the desired surface profile can then be corrected before defective parts are produced. The major conclusions of this study are as follows. Bayesian parameter estimation is able to separate entangled Lamb wave modes. Pattern recognition algorithms applied to Lamb mode features have produced robust features for distinguishing between several types of weld defects. In other words, the information is present in the output of the laser ultrasonic hardware, and it is feasible to extract it. Wavelet analysis produces results that are almost as good as Bayesian, but execute a thousand times faster. This study demonstrates the principle that it is feasible to construct a laser ultrasonic system to detect weld defects in thin metal parts on-line in real-time, and to classify the defects according to type.

Power System Dynamic Stability Improvement with UPFC using LQR Technique

Many damping controller devices based on other techniques have been proposed time to time. For the study of the damping performance, it has been proposed a power systems model with ‘UPFC’ and power oscillation damping controller in the present article. The proposed controller performance has been studied under different simulation condition results and that also includes various loading condition, i.e., normal with 100 percent, under loading 80 percent and overloading with 120 percent at different operational points. Finally, a better result has been observed by using the proposed damping controlling device than earlier available existing devices. However, the result obtained by using Eigen value analysis is supported by the facts obtained by the settling time analysis and the analysis of simulation results
A Simple Formula for the Capacitance of a Disc on Dielectric on a Plane

There is presented a simple explicit formula for the capacitance of a thin circular disc on a dielectric substrate on a plane (so-called "microstrip"). It gives continuous coverage of all shape ratios (r/h) and all dielectrics (k). The formula is developed by transition between asymptotic formulas for small and large discs, and by interpolation between bounding formulas for lo- k and hi- k. The presentation and devlopment are facilitated by a reference formula which is the sum of the C is less than 0.004 for all conditions
The analysis of optical transmission in three-dimensional waveguide coupler

Optical waveguide directional couplers can perform some very useful functions in a variety of integrated optical applications, especially when the branch arm incorporates gain. In this paper, the performance of three-dimensional active optical waveguide directional coupler is analyzed by finite-difference beam propagation method (FD-BPM). The paper analyses the impact of normalized gain difference and normalized phase difference on optical power transfer characteristics. The transmission characteristics of three-dimensional active waveguide coupler in phase matching and mismatching are discussed in detail. In addition, the influence of geometric parameters of three-dimensional waveguide coupler on the transmission characteristics is analyzed. The result of above analysis can be helpful for optimizing the active coupler designing.

Who Signs What

By its essential nature, a national library is one of the most representative institutions in the culture of each country and, for that reason, its main objective is the general culture of the country. Today, one of the roles played by national libraries is to refer to the cultural identity of a country, that is to say, national libraries are seen as cultural flags, as a sign of respect to the unity of a country, as well as evidence of the importance of the national culture in the world and through history. From the beginning, national libraries appear as a proof of the power of the monarchies, so that in France, England, Spain, and so on, the Royal Library is another of the varied signs of the power of the kings. The endeavours of Phillip II in Spain or Louis XIV in France to have very good libraries can be cited, and we can suppose that the real objective was not the library in itself, but the library considered as a proof of power, of cultural power. The French Revolution, in 1789, made the change in the Royal Library to what then was – and is – considered as a ‘National’ Library, the Library of the Nation, the nation being the site of power, and power located in the hands of the citizen, not of the kings. The national library is now seen as the representative of a new idea: the nation is the concretization of a new society, the people’s society, and the national library represents the general culture of the nation. Gradually, the concept of the national library acquires a new meaning: to be, through the support of knowledge by various means, the physical proof of the contribution of a country to universal culture. This is done in two ways: firstly, with collections of essential materials and secondly, using them by means of the national bibliography to define ‘the record of the cultural,
