    Self-phase modulation induced spectral broadening has been observed for ultrashort pulses propagating through Ta2O5 rib waveguide. The associated nonlinear refractive index was estimated to be 7.23 x10-19 m2/W, which is higher by one order of magnitude than silica glass

    On-load Tap Changer Diagnosis on High-Voltage Power Transformers using Dynamic Resistance Measurements

    No full text
    High-voltage transformers have tap changers to regulate the voltage in the high-voltage network when the load changes. Those tap changers are subject to different degradation mechanisms and need regular maintenance. Various defects, like contact degradation, often remain undetected and the probability of maintenance errors cannot be neglected. Preventive diagnosis of dynamic resistance can be used to determine the contact condition and to check the basic function of the tap changer. This can guarantee that the high-voltage transformer can be put back into operation safely after maintenance. In addition, the information obtained can be used for condition-based maintenance. The research of Jur Erbrink elaborates on the condition assessment of tap changers using dynamic resistance measurements. He describes in his thesis the different ways in which the measurements can be performed and how this influences the measurement results. In particular it was emphasized that the dynamic resistance measurements at a lower the test current are more sensitive for long term aging effects. It is also investigated which defects can be detected and how the results can be interpreted.High Voltage Technology and ManagementElectrical Engineering, Mathematics and Computer Scienc

    Psychological Therapies, Psychological Therapists, Psychological Models of Mental Disorder and the Role of Applied Psychologists

    Guidelines from NICE (the National Institute for Health and Clinical Excellence) and academic papers have repeatedly stressed the effectiveness and appropriateness of psychological therapies for a range of mental health problems. The Department of Health’s and the Care Services Improvement Partnership’s (CSIP) Programme Improving Access to Psychological Therapies (IAPT) sets out a framework for action, including two national demonstration sites, to address these issues in England. Clearly, as experts in conducting and delivering psychological interventions, clinical and applied psychologists have a key role here. Psychologists are the key profession delivering such therapies, but the IAPT programme envisages an expansion of psychological therapists more generally. This means commissioners contracting with NHS Trusts (and potentially other bodies) to employ a range of professionals, including new graduates, to be trained in specific therapies such as cognitive behavioural therapy (CBT). Therefore, psychologists are also important as managers, supervisors and trainers of such psychological therapists. Psychologists’ training enables them to formulate individualised complex care plans where the application of manualised and deliverable packages of therapy can be integrated into more holistic care plans. This paper discusses the distinctive roles of psychologists and psychological perspectives in the light of these proposals. The paper is written from the perspective of one professional group – clinical psychology – and should be read in that context

    Among the varied programs offered by the Library during the Spring, a series of lectures, Fables: From Aesop to La Fontaine, gets a page of recognition. The series is done by Marcel M. Gutwirth. It is meant to support and coincide with the Library's La Fontaine: The Power of Fables exhibition, co-curated by Paul LeClerc. The booklet features eight outstandingly-reproduced engravings by J.J. Grandville, including the cover engraving of the two high-society goats unable to pass through the doorway at the same time.Paul LeClerc
