Comprehensive knowledge of the complicated physical behavior of the induction furnace with cold crucible (IFCC) is required to utilize the advantages of this melting aggregate in melting and casting chemically high‐reactive materials, like titanium‐aluminides (TiAl). Practical experiences show that the overheating temperature of the melt is decisive for the quality of the cast products. Therefore, a systematic analysis of the electromagnetic and in particular, the hydrodynamic and thermal behavior of the IFCC is carried out. The examinations of the influence of the construction elements as well as the process parameters on the temperature field and finally the overheating temperature in the IFCC are performed using specifically developed numerical models. The evaluation of the numerical results is done by experimental investigations, where aluminum serves as a model melt for the experimental determination of the thermal and hydrodynamic field of the melt. The analysis of the influence of construction‐elements on the overheating temperature is focused on the design of the crucible wall and the crucible bottom, on the height‐diameter ratio of the crucible and on the axial inductor position. The inductor current, the operation frequency and the crucible filling level are found to be very important for reaching a high overheating temperature.

This paper aims to demonstrate the benefits of using different impeder materials for induction tube welding systems.

To show the difference in using various impeder materials, a new approach was taken to model tube welding systems in two and three dimensions. Three-dimensional (3-D) electromagnetic models were used to determine the current distribution along the weld vee as well as the permeability of the tube along the length of the welding system. Two-dimensional (2-D) coupled electromagnetic plus thermal models with rotational movement were used to determine the temperature distribution in the heat-affected zone.

Simulation results suggest upwards of 25 per cent system power savings when using a soft magnetic composite (SMC) impeder rather than the traditional ferrites.

There is currently a lack of experimental data to validate the models, but future work will include comparison of models to real-world trials.

When dealing with tube welding systems, there are possibilities to improve process efficiency or increase production quality and output by improving the impeder material.

While simulations of tube welding systems have been done previously, studies on improving impeder materials are rarely carried out. This paper brings to light possible improvements to be made to induction tube welding systems.

The purpose of this paper is to introduce a numerical calculation method to study the uniformity of the magnetic field in a cold crucible used for directional solidification (DS) and provide information for designing a cold crucible that can induce a uniform magnetic field.

To obtain the characteristics of the magnetic field in a cold crucible and its influence on the directional solidification processing, based on experimental verification, 3‐D finite element (FE) models with different crucible configuration‐elements and power parameters were established to study the uniformity of the magnetic field in a cold crucible. In addition, different TiAl ingots were directionally solidified with different cold crucibles, and the solid/liquid (S/L) interfaced were examined to investigate the effect of the magnetic field on the macrostructure of those ingots.

The uniformity of the magnetic field in a given domain can be quantitatively analyzed by statistical methods. Numerical calculation results showed that the uniformity of the magnetic field can be improved by optimizing the crucible configuration and adopting lower frequency. Better uniformity of the magnetic field in a cold crucible is beneficial to directional solidification.

The calculation of the uniformity of the magnetic field is proposed as a method for quantitative study of the distribution characteristics of the magnetic field in a cold crucible. The relationship between the S/L interfaces of TiAl ingots and the uniformity of the magnetic field is initially characterised; additionally, techniques for improving the uniformity of the magnetic field in a cold crucible are suggested.

An overview of the current use of handwritten text recognition (HTR) on archival manuscript material, as provided by the EU H2020 funded Transkribus platform. It explains HTR, demonstrates Transkribus, gives examples of use cases, highlights the affect HTR may have on scholarship, and evidences this turning point of the advanced use of digitised heritage content. The paper aims to discuss these issues.

This paper adopts a case study approach, using the development and delivery of the one openly available HTR platform for manuscript material.

Transkribus has demonstrated that HTR is now a useable technology that can be employed in conjunction with mass digitisation to generate accurate transcripts of archival material. Use cases are demonstrated, and a cooperative model is suggested as a way to ensure sustainability and scaling of the platform. However, funding and resourcing issues are identified.

The paper presents results from projects: further user studies could be undertaken involving interviews, surveys, etc.

Only HTR provided via Transkribus is covered: however, this is the only publicly available platform for HTR on individual collections of historical documents at time of writing and it represents the current state-of-the-art in this field.

The increased access to information contained within historical texts has the potential to be transformational for both institutions and individuals.

This is the first published overview of how HTR is used by a wide archival studies community, reporting and showcasing current application of handwriting technology in the cultural heritage sector.

While much research examines the consequences of deinstitutionalization for caregivers, few studies address support mobilization strategies used by patients themselves. We examine the relationship between mental health patients’ needs, their activation of network ties for health discussion, and network dynamics during the course of treatment. We hypothesize that patients strategically activate their network ties for support that matches their needs. Linking activation to network dynamics, we also propose that patients with greater needs exhaust their supportive relationships and experience more network turnover.

We draw on a dataset of new mental health patients (N=173) and their associated network members (N=4,144) observed over three years. Random-intercept regression models test the relationship between patients’ needs and (1) network tie activation for health discussion and (2) network turnover.

Although the overall level of need does not predict network tie activation, mental health patients are more likely to activate network ties who provide support that matches their expressed needs for discussion, emotional, and financial support (although not instrumental or informational support). In addition, patients with elevated needs experience increased network turnover. Strategic activation and its unintended consequence together suggest a revolving door of support for patients in crisis.

In the post-deinstitutionalization era, patients’ informal social safety nets must compensate for needs that are left unmet by deficits in the formal treatment system. We find that patients seek out network members who are well-equipped to help them cope with the onset of illness. At the same time, network activation may lead to instability as high-need patients churn through supportive relationships. Future research should examine the consequences of tie activation and support needs for network dynamics in different treatment contexts.

Recent years have seen the emergence of the recovery perspective. However, as yet there is no overriding theoretical framework which supports our understanding of recovery and its counterpart, stigma. In large part this is because discourses concerning mental health remain dominated by the medical model and an illness ideology, even though there is growing interest in more socially defined determinants of disability. We propose symbolic interaction as a theoretical framework which might address this shortcoming. Published literature concerning the use of this approach in the mental health field is reviewed and we discuss the implications and ways forward for future research on mental health, stigma and recovery. In particular, we consider how this approach can help identify ways in which contemporary practices and conventions might inadvertently hinder recovery and contribute towards a disabled self.

Caring for a person with a substance use disorder (SUD) and/or mental health disorder (MHD) represents a significant burden for family members. The features of “carers/family members” experiences reflect trauma signatures. Consequently, working through this trauma for carers corresponds with psychological recovery, empowerment processes and intrapersonal/interpersonal needs. The purpose of this paper is to outline a framework called the “personal and relational empowerment (PRE)” framework which enables family support practitioners to help family members to be able to take control of their own lives, develop meaningful relationships and live purposeful and fulfilling lives, regardless of whether the person with the SUD and/or MHD is in recovery or not.

This paper critically reviews existing frameworks for carer recovery, through a systematic literature search, and proposes a “PRE” alternative to redress the shortfalls in these existing frameworks.

The PRE framework takes a multi-level needs-based approach to understand carer recovery. This framework links the concepts – psychological recovery, empowerment processes and intrapersonal/interpersonal needs.

The PRE framework recognises the importance of recovery support practitioners being able to balance the immediate carer crisis intervention needs responses with personal growth and well-being supporting interventions.

The PRE framework of family recovery attempts to answer the need to broaden the focus on the family journey to better reflect the principles and practices of contemporary SUD and/or MHD recovery-based support.

In the years 1999 and 2000 the Universities of Hannover and Padua and four industrial partners from Italy and Germany have developed a common research project on TFH financed by the EU (Project JOE3‐CT98‐7023). In this paper, the main results obtained are shortly described.

The purpose of this paper is obtaining the optimal parameters of induction heating and melting systems by use of the new programs ELectro-Thermal Analysis (ELTA) 8.0 and Induction Crucible Furnace (ICF) to improve a quality of final products.

Simulation of continuous through heating prior a drawing through the draw plate is realized by an optimization procedure. Additional application of ELTA 8.0 “Heating of Wire” reveals the relationship between power, time and thermal profile of load during heating. Rational variants of ICFs for melting processes are obtained using several step-by-step iterations.

ELTA 8.0 program permits to optimize the continuous heating of copper, steel, titanium and other wires. ICF ELTA program was used at the initial stage of the development of new technological processes and the ICFs. This program provides a preliminary evaluation of an induction melting process and system before the use of more sophisticated 2D or 3D programs. Results of optimization allowed to find a rational decision of an induction system, the required parameters of a refractory and a power supply. Non-conductive and graphite crucibles of the furnace were compared from electrical and economical points of view.

Fast calculation of ELTA programs allows the designer to provide the required temperature distribution in a cross section and along the part to control the real-time processes of heating and melting.
