    A major open question in astrophysics concerns the formation of highly collimated beams of matter and electromagnetic radiation, so-called relativistic jets, emerging from active galactic nuclei (AGN) in the center of certain galaxies. It is not known how, or why, these jets are formed nor how they maintain their collimated state for such large distances. For long it has been thought that jets can only be hosted in large, elliptical galaxies, though quiterecently AGNs have been discovered that contradict these beliefs. These objects are called radio-loud narrow-line Seyfert 1 galaxies (RLNLSy1). In this thesis an AGN belonging to this class is analysed. Utilising an X-ray spectral fitting package (XSPEC), data from two separate observations obtained from the X-ray Multi-Mirror Mission observatory (XMM-Newton) of the radio-loud narrow-line Seyfert 1 galaxy SDSS J154817.92+351128.0 are fitted through the use of different models and analysed in the energy region of 0.3 keV to 10 keV. The purpose is to disentangle the emission from the light-emitting accretion disk surrounding the central supermassive black hole(SMBH) and the emission from a possible jet, as well as to determine their properties. The results indicate a strong presence of a jet while still maintaining a visible spectrum from the accretion disk. No sign of the Fe line, usually seen in radio-quiet NLSy1s, can be detected, even though the data is not of sufficientquality to exclude the possibility of detection. Furthermore, considerable amounts of enhanced emission below 2 keV is observed, a so-called soft excess. The soft excess could be explained by inverse comptonisation of the light emitted from the disk and/or reflections in the disk. Our results confirm the presence of powerful relativistic jets emerging from J1548+3511. The wider implications of jet formation are further discussed

    The purpose of the NASA University Program Review Conference was to describe the nature of the Program, the manner in which it is being conducted, the results that it is producing, and the impact it may be having. The presentations, except for some expository papers by NASA offi- cials, were made by members of the university and nonprofit community. ference message as it has come to me, a university professor spending a year in making a study of NASA-University relations under a NASA contract with my institution. In preparing the report, my guiding principle has been to try to maximize its usefulness by making it accurate, brief, and prompt. These qualities are largely incompatible, and I am sure that the result of my search for an optimum compromise will please no one. Open editorializing is mainly confined to a brief section constituting my Evaluation of Program. The complete transcript will shortly be available, to stand as the authoritative source for statements that anyone may wish to attribute to the speakers

    Overview of Remaining Useful Life prediction techniques in Through-life Engineering Services

    Get PDF
    Through-life Engineering Services (TES) are essential in the manufacture and servicing of complex engineering products. TES improves support services by providing prognosis of run-to-failure and time-to-failure on-demand data for better decision making. The concept of Remaining Useful Life (RUL) is utilised to predict life-span of components (of a service system) with the purpose of minimising catastrophic failure events in both manufacturing and service sectors. The purpose of this paper is to identify failure mechanisms and emphasise the failure events prediction approaches that can effectively reduce uncertainties. It will demonstrate the classification of techniques used in RUL prediction for optimisation of products’ future use based on current products in-service with regards to predictability, availability and reliability. It presents a mapping of degradation mechanisms against techniques for knowledge acquisition with the objective of presenting to designers and manufacturers ways to improve the life-span of components

    Promoting Academic Entrepreneurship in Europe and the United States: Creating an Intellectual Property Regime to Facilitate the Efficient Transfer of Knowledge from the Lab to the Patient

    In 2014, the European Commission announced the launch of a study of knowledge transfer by public research organizations and other institutes of higher learning “to determine which additional measures might be needed to ensure an optimal flow of knowledge between the public research organisations and business thereby contributing to the development of the knowledge based economy.” As the European Commission has recognized, the European Union (“EU”) needs to take action to “unlock the potential of IPRs [intellectual property rights] that lie dormant in universities, research institutes and companies.” This article builds on our earlier work on structuring efficient pharmaceutical public-private partnerships (“PPPPs”), but focuses on the regulatory infrastructure necessary to support the efficient commercialization of publicly funded university medical research in both the European Union and the United States (“U.S.”). Our comparative analysis of the EU and U.S. approaches to translational medicine shows that there are lessons to be shared. The EU can apply the experiences from the U.S. Bayh-Dole Act and PPPPs in the United States, and the United States can emulate certain of the open innovation aspects of the European Innovative Medicines Initiative and the tighter patenting standards imposed by the European Patent Office. Thus, a secondary purpose of this article is suggesting amendments to the U.S. laws governing the patenting and licensing of government-funded technology to prevent undue burdens on the sharing of certain upstream medical discoveries and research tools
