    Condition monitoring systems of manufacturing processes have been recognised in recent years as one of the key technologies that provide the competitive advantage in many manufacturing environments. It is capable of providing an essential means to reduce cost, increase productivity, improve quality and prevent damage to the machine or workpiece. Turning operations are considered one of the most common manufacturing processes in industry. It is used to manufacture different round objects such as shafts, spindles and pins. Despite recent development and intensive engineering research, the development of tool wear monitoring systems in turning is still ongoing challenge. In this paper, force signals are used for monitoring tool-wear in a feature fusion model. A novel approach for the design of condition monitoring systems for turning operations using novelty detection algorithm is presented. The results found prove that the developed system can be used for rapid design of condition monitoring systems for turning operations to predict tool-wear

    \ua9 Author(s) (or their employer(s)) 2024.Reading for Wellbeing (RfW) is a pilot initiative, aimed at improving mental health and well-being through supporting access and increasing opportunities to read for pleasure. RfW was implemented across six North-East local authorities in England and employed Community Reading Workers to support access to books and reading for targeted populations. The current study used realist methodology to understand context, potential mechanisms of action, acceptability and reported outcomes. Data generation and analysis were conducted iteratively, using focus groups, interviews and observations. The analysis of the collated data highlighted that a positive attitude towards reading and a desire for social connections were significant motivators for engagement with RfW. This paper postulates eight programme theories relating to that context, which describe key mechanisms within RfW linked to engagement with reading, well-being, connections and practice. The paper concludes that previous notions of positivity associated with reading for pleasure enable participants to experience RfW as a positive social encounter. This positive social encounter enhances participants’ multiple resistance resources such as increased sense of self-efficacy and connectedness that could impact on their sense of well-being

    Do Policy Implementation Support Programmes Work? The Case of the Care Act 2014

    Get PDF
    Context: Policy implementation is an often overlooked stage when policy is introduced. Too often the result is policy failure caused by overly optimistic expectations, implementation in dispersed governance, inadequate collaborative policy-making, and the vagaries of the political cycle. The Care Act 2014 introduced the most significant change in social care law in England for 60 years. Given the complexity of the changes, the Department of Health and Social Care and its key partners introduced an Implementation Support Programme (ISP) to increase the likelihood of smooth implementation. Objective: To assess the impact of the ISP on local implementation of the Care Act and develop a framework for understanding the requirements of a successful ISP. Methods: Analysis was undertaken of the relevant theoretical and conceptual literature in addition to a review of support programmes for other national policies. The empirical study of the impact of the Care Act’s ISP, conducted in six local authorities, focused on three levels of activity that shaped outcomes: national, regional and local. Data were collected through interviews with key stakeholders at each level. Findings: The ISP enjoyed several successes including: helping to secure policy legitimacy, developing stakeholder engagement, sustaining political support, and ensuring the readiness of local implementation agencies. Limitations: The empirical research was confined to six English local authorities which limits drawing general conclusions applicable to the whole country. Implications: Little evidence exists on the value of ISPs. The research goes some way to closing the gap and offers provisional messages on their value to policy-makers and practitioners

    Dietary experience modifies horses' feeding behavior and selection patterns of three macronutrient rich diets

    Choice feeding is often used to investigate an animal’s nutritional requirements and dietary preferences. A problem with this approach is that animals with long gut transit times, such as the horse, may find it difficult to associate a chosen food with its nutritional consequence when alternative foods are presented simultaneously. One solution is to present foods singly for a period of time before a simultaneous choice session to allow the development of learned associations. This method was used to determine if horse’s voluntary intake and feeding behavior was influenced by the macronutrient composition of the diet. Seven stabled horses, maintained on a low intensity exercise regimen, were allowed, on an ad libitum basis, haylage and 3 isocaloric forage based diets that were rich in 1 of 3 macronutrients (protein, lipid, and hydrolyzable carbohydrate). Initially, diets were presented as a 3-way choice for 5 d (self-selection a [SSa]), then singly (monadic phase) with exposure to each diet for 2 separate periods of 3 d each, and finally again as a choice for 5 d (self-selection b [SSb]). The total amount of trial diet offered differed with trial phase, with 2 to 2.5% of BW during SSa and the monadic phase, increasing to ad libitum access during SSb. To control differences in the total amount of trial diet offered, 2 measurements of voluntary intake were taken at 4 and 22 h postpresentation. Daily macronutrient and energy intakes were estimated from proximate analysis of the trial diets and batches of haylage fed. Feeding behavior was observed over a single 4-h period during both self-selection phases. Horses showed no initial preference after 4 h for any 1 diet during SSa. Following the monadic phase, horses demonstrated a preference for the protein and hydrolyzable carbohydrate rich diets over the lipid rich diet (P < 0.001). Dietary experience modified foraging behavior as the total number of visits to the diets decreased during SSb (P < 0.005). Analysis of 24 -h macronutrient consumption showed that protein and hydrolyzable carbohydrate intake increased during SSb, whereas lipid intake remained constant over both self-selection phases (P < 0.001). These data indicate for perhaps the first time that horses can respond to dietary macronutrient content and that single presentations during choice studies facilitates expression of dietary preferences

    A realist approach to understanding alliancing within Local Government public health and social care service provision’

    Get PDF
    Background: Within the current context of continued austerity and post pandemic recovery, it remains important that Local Government services address the increasing needs of residents as cost-effectively as possible. Alliancing, whereby services work collaboratively focusing on the ‘whole-system’, has gained popularity as a tool with the potential to support collaborative whole systems approaches. This synthesis aims to identify how alliancing can be successfully operationalised in the commissioning of public health, wider NHS, and social care related services. Methods: A realist literature synthesis was undertaken in order to identify underlying generative mechanisms associated with alliancing, the contextual conditions surrounding the implementation and operationalisation of the alliancing approach mechanisms, and the outcomes produced as a result. An iterative approach was taken, using a recent systematic review of the effectiveness of Alliancing, online database searches, and grey literature searches. Results: Three mechanistic components were identified within the data as being core to the successful implementation of alliances in public health and social care related services within Local Government: (1) Achieving a system level approach; (2) placing local populations at the heart of the system; and (3) creating a cultural shift. Programme theories were postulated within these components. Conclusions: The alliancing approach offers an opportunity to achieve system-level change with the potential to benefit local populations. The realist synthesis approach taken within this study has provided insights into the necessary contextual and mechanistic factors of the Alliancing approach, above and beyond effectiveness outcomes typically collected through more conventional evaluation methodologies

    Highlights lecture EANM 2015: the search for nuclear medicine’s superheroes

    Get PDF
    The EANM 2015 Annual Congress, held from October 10th to 14th in Hamburg, Germany, was outstanding in many respects. With 5550 participants, this was by far the largest European congress concerning nuclear medicine. More than 1750 scientific presentations were submitted, with more than 250 abstracts from young scientists, indicating that the future success of our discipline is fuelled by a high number of young individuals becoming involved in a multitude of scientific activities. Significant improvements have been made in molecular imaging of cancer, particularly in prostate cancer. PSMA-directed PET/CT appears to become a new gold standard for staging and restaging purposes. Novel tumour specific compounds have shown their potential for target identification also in other solid neoplasms and further our understanding of tumour biology and heterogeneity. In addition, a variety of nuclear imaging techniques guiding surgical interventions have been introduced. A particular focus of the congress was put on targeted, radionuclide based therapies. Novel theranostic concepts addressing also tumour entities with high incidence rates such as prostate cancer, melanoma, and lymphoma, have shown effective anti-tumour activity. Strategies have been presented to improve further already established therapeutic regimens such as somatostatin receptor based radio receptor therapy for treating advanced neuroendocrine tumours. Significant contributions were presented also in the neurosciences track. An increasing number of target structures of high interest in neurology and psychiatry are now available for PET and SPECT imaging, facilitating specific imaging of different subtypes of dementia and movement disorders as well as neuroinflammation. Major contributions in the cardiovascular track focused on further optimization of cardiac perfusion imaging by reducing radiation exposure, reducing scanning time, and improving motion correction. Besides coronary artery disease, many contributions focused on cardiac inflammation, cardiac sarcoidosis, and specific imaging of large vessel vasculitis. The physics and instrumentation track included many highlights such as novel, high resolution scanners. The most noteworthy news and developments of this meeting were summarized in the highlights lecture. Only 55 scientific contributions were mentioned, and hence they represent only a brief summary, which is outlined in this article. For a more detailed view, all presentations can be accessed by the online version of the European Journal of Nuclear Medicine and Molecular Imaging (Volume 42, Supplement 1)
