    The aim of a joint research and development project at the BME and HWU is to produce a cheap, reliable, low-power and CMOS-MEMS process compatible capacitive type relative humidity (RH) sensor that can be incorporated into a state-of-the-art, wireless sensor network. In this paper we discuss the preparation of our new capacitive structure based on post-CMOS MEMS processes and the methods which were used to characterize the thin film porous alumina sensing layer. The average sensitivity is approx. 15 pF/RH% which is more than a magnitude higher than the values found in the literature. The sensor is equipped with integrated resistive heating, which can be used for maintenance to reduce drift, or for keeping the sensing layer at elevated temperature, as an alternative method for temperature-dependence cancellation.Comment: Submitted on behalf of EDA Publishing Association (http://irevues.inist.fr/handle/2042/16838

    This research is a study on the refurbishment of old building and heritage building in Malaysia. This research intends to highlight the existing practice on rehabilitation projects in Malaysia with the main focus on guidelines at rehabilitation work stages. Besides that, this research describes building restoration and the process of the renewal and refurbishment of the fabric of a building. The objectives of doing this research are to emphasize the importance of refurbishment in order to reserve an old and historical building without make big changes at the façade and structure of the buildings. This research also important in order to study on the space utilization for internal after the buildings have been refurbished and finally to determine various of commercial building that have been refurbished for a new facilities and find the most rapidly area with the preservation and conservation of buildings. The phase covers a wide span of activities, from the cleaning of the interior or exterior of a buildings Buildings are structures which have, from time to time, particular purposes. They require ongoing maintenance to prevent them falling into disrepair as a result of the ravages of time and use. Building restoration can be thought of as that set of activities which are greater than year-to-year maintenance. This research was held at Malacca, Batu Pahat and Muar. This is because; there is many old building and historical building that constructed during the British Colonial and others. The design gave an aesthetic value to the tourist. Based on this research, Malacca is the most rapid area with a refurbishment development because Malacca was awarded with World Heritage List by UNESCO. It is important for Malacca to maintain their historic and aesthetic value of the buildings. Batu Pahat was found the slowest region in refurbishment development

    Integrating Neural Networks with a Quantum Simulator for State Reconstruction

    We demonstrate quantum many-body state reconstruction from experimental data generated by a programmable quantum simulator, by means of a neural network model incorporating known experimental errors. Specifically, we extract restricted Boltzmann machine (RBM) wavefunctions from data produced by a Rydberg quantum simulator with eight and nine atoms in a single measurement basis, and apply a novel regularization technique to mitigate the effects of measurement errors in the training data. Reconstructions of modest complexity are able to capture one- and two-body observables not accessible to experimentalists, as well as more sophisticated observables such as the R\'enyi mutual information. Our results open the door to integration of machine learning architectures with intermediate-scale quantum hardware.Comment: 15 pages, 13 figure

    Development of the target therapies of lung cancer was a rapid process which fundamentally changed the pathological diagnosis as well. Furthermore, molecular pathology became essential part of the routine diagnostics of lung cancer. These changes generated several practical problems and in underdeveloped countries or in those with reimbursement problems have been combined with further challenges. The central and eastern region of Europe are characterized by similar problems in this respect which promoted the foundation of NSCLC Working Group to provide up to date protocols or guidelines. This present paper is a summary of the molecular pathology and target therapy guidelines written with the notion that it has to be upgraded continuously according to the development of the field

    First identification of excited states in the Tz_z = 1/2 nucleus 93^{93}Pd

    No full text
    The first experimental information about excited states in the N = Z + 1 nucleus 93Pd is presented. The experiment was performed using a 205 MeV 58Ni beam from the Vivitron accelerator at IReS, Strasbourg, impinging on a bismuth-backed 40Ca target. Gamma-rays, neutrons and charged particles emitted in the reactions were detected using the Ge detector array Euroball, the Neutron Wall liquid-scintillator array and the Euclides Si charged-particle detector system. The experimental level scheme is compared with the results of new shell model calculations which predict a coupling scheme with aligned neutron-proton pairs to greatly influence the level structure of NZN\approx Z nuclei at low excitation energies

    Relative spins and excitation energies of superdeformed bands in 190Hg: Further evidence for octupole vibration

    Get PDF
    An experiment using the Eurogam Phase II gamma-ray spectrometer confirms the existence of an excited superdeformed (SD) band in 190Hg and its very unusual decay into the lowest SD band over 3-4 transitions. The energies and dipole character of the transitions linking the two SD bands have been firmly established. Comparisons with RPA calculations indicate that the excited SD band can be interpreted as an octupole-vibrational structure.Comment: 12 pages, latex, 4 figures available via WWW at http://www.phy.anl.gov/bgo/bc/hg190_nucl_ex.htm

    Chronology of Pleistocene sedimentary cycles in the western Mediterranean

    [eng] This study focuses on the sedimentological and stratigraphic description and chronology of Pleistocene coastal deposits on the Pityusic Islands (Balearic Islands, Spain). These deposits show evidence of interference between processes characteristic of alluvial, marine, and aeolian environments. Optically stimulated luminescence dating of aeolian levels indicates that deposition took place from the Lower to Upper Pleistocene. The sedimentological and chronological analysis of these deposits allows reconstruction of coastal Pleistocene environmental history from MIS 22 to MIS 2. The results show that changes in the average wind direction over time, modulated by the interaction with coastal relief orientation, were the main controls on the Lower to Upper Pleistocene coastal landscape evolution on the Pityusic Islands. The main episodes of aeolian activity identified in the Western Mediterranean, can be linked to periods of low sea level. The study's findings the presence of two dominant environments, coastal aeolian and alluvial, each characterized by distinct geological processes. Interestingly, these processes have led to the formation of deposits that exhibit a combination of characteristics from both environments. Moreover, these deposits retain elements inherited from each environment in terms of sedimentary supply, precipitation, runoff or aeolian transport. These results corroborated by OSL dating provide a useful indicator of the geomorphological processes and changes that occurred during the Pleistocene, unraveling the environmental evolution, and contributing to the growing knowledge on western Mediterranean aeolian or aeolian-alluvial interacting environments during the last 1000 ka
