    Reconstruction of geospatial networks (2016)
    Royal Society
    Details
    Publication Date: 2016-01-30
    Description: Given a complex geospatial network with nodes distributed in a two-dimensional region of physical space, can the locations of the nodes be determined and their connection patterns be uncovered based solely on data? We consider the realistic situation where time series/signals can be collected from a single location. A key challenge is that the signals collected are necessarily time delayed, due to the varying physical distances from the nodes to the data collection centre. To meet this challenge, we develop a compressive-sensing-based approach enabling reconstruction of the full topology of the underlying geospatial network and more importantly, accurate estimate of the time delays. A standard triangularization algorithm can then be employed to find the physical locations of the nodes in the network. We further demonstrate successful detection of a hidden node (or a hidden source or threat), from which no signal can be obtained, through accurate detection of all its neighbouring nodes. As a geospatial network has the feature that a node tends to connect with geophysically nearby nodes, the localized region that contains the hidden node can be identified.

    Hydrodynamic optimization of trust ring pump and lubricating oil system for large hydroelectric units thrust bearing (2014)
    Institute of Physics (IOP)
    Details
    Publication Date: 2014-12-11
    Description: Thrust-ring-pump is a kind of extreme-low specific speed centrifugal pump with special structure as numerous restrictions form thrust bearing and operation conditions of hydro turbine generator unit. Because the oil circulating and cooling system with thrust-ring- pump has a lot of advantages in maintenance and compactness in structure, it has widely been used in large and medium-sized hydro-generator units. Since the diameter and the speed of the thrust ring is limited by the generator set, the matching relationship between the flow passage inside the thrust ring (equivalent to impeller) and oil bath (equivalent to volute) has great influence on hydrodynamic performance of thrust-ring-pump, additionally, the head and discharge are varying with the operation conditions of hydro-generator unit and characteristic of the oil circulating and cooling system. As so far, the empirical calculation method is employed during the actual engineering design, in order to guarantee the operati...

    Influence of initial nozzle opening on the maximum pressure head at the impulse turbine inlet and set of needle closing law (2014)
    Institute of Physics (IOP)
    Details
    Publication Date: 2014-12-11
    Description: The maximum pressure head at the impulse turbine inlet is one of the most important parameters for operation of the impulse turbine. In order to determine the most critical operating condition for the maximum pressure head rise at the impulse turbine inlet, the formula which demonstrates the relation between relative pressure head and the initial opening is obtained through theoretical derivation. It shows a good agreement with the numerical results by the method of characteristics. A parabolic shaped flow characteristic of the nozzle is utilized in the derivation. Besides, the fact that the maximum pressure often occurs in the moment of the first wave reflection for the hydropower plants with impulse turbines is considered. The formula indicates that the maximum of pressure head rise increases monotonously with the initial opening decreasing. Therefore, the most critical condition for the maximum pressure head at the impulse turbine inlet is the condition of load rejection from...

    Appliance-Aware Activity Recognition Mechanism for IoT Energy Management System (2013)
    Oxford University Press
    Details
    Publication Date: 2013-07-31
    Description: The Internet of Things (IoT) interconnects Internet and end device networks connected by identification information, which not only extends and explores the range of the Internet, but also constructs bridges of communication between realistic objects and the Internet. With increasing awareness about the energy crisis, the development of intelligent energy-saving systems has become a new trend in all circles. This work proposes an appliance-aware activity recognition mechanism for an IoT energy management system, and especially an intermediate management service layer for the conformability of current household appliances, which not only establishes communication services among various appliances, but also provides services for upper-layer application based on a service-oriented architecture. Further, the presented system has the capability to deduce human activities from appliances being used and the variation of their states, and provide energy management services. In other words, the system can identify home activities at present, and notify users what unused appliance is or turn them off automatically. According to experiment results, improving the usage behaviour of appliances by means of a remainder system improves the efficiency in saving household electricity.

    Present-day crustal deformation in China constrained by global positioning system measurements (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-10-20
    Description: Global Positioning System (GPS) measurements in China indicate that crustal shortening accommodates most of India's penetration into Eurasia. Deformation within the Tibetan Plateau and its margins, the Himalaya, the Altyn Tagh, and the Qilian Shan, absorbs more than 90% of the relative motion between the Indian and Eurasian plates. Internal shortening of the Tibetan plateau itself accounts for more than one-third of the total convergence. However, the Tibetan plateau south of the Kunlun and Ganzi-Mani faults is moving eastward relative to both India and Eurasia. This movement is accommodated through rotation of material around the eastern Syntaxis. The North China and South China blocks, east of the Tibetan Plateau, move coherently east-southeastward at rates of 2 to 8 millimeters per year and 6 to 11 millimeters per year, respectively, with respect to the stable Eurasia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Q -- Zhang, P Z -- Freymueller, J T -- Bilham, R -- Larson, K M -- Lai, X -- You, X -- Niu, Z -- Wu, J -- Li, Y -- Liu, J -- Yang, Z -- Chen, Q -- New York, N.Y. -- Science. 2001 Oct 19;294(5542):574-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Seismology, China Seismological Bureau, Wuhan 430071, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11641493" target="_blank"〉PubMed〈/a〉

    Adaptive immune response of Vgamma2Vdelta2+ T cells during mycobacterial infections (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-03-23
    Description: To examine the role of T cell receptor (TCR) in gammadelta T cells in adaptive immunity, a macaque model was used to follow Vgamma2Vdelta2+ T cell responses to mycobacterial infections. These phosphoantigen-specific gammadelta T cells displayed major expansion during Mycobacterium bovis Bacille Calmette-Guerin (BCG) infection and a clear memory-type response after BCG reinfection. Primary and recall expansions of Vgamma2Vdelta2+ T cells were also seen during Mycobacterium tuberculosis infection of naive and BCG-vaccinated macaques, respectively. This capacity to rapidly expand coincided with a clearance of BCG bacteremia and immunity to fatal tuberculosis in BCG-vaccinated macaques. Thus, Vgamma2Vdelta2+ T cells may contribute to adaptive immunity to mycobacterial infections.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2872146/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2872146/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, Yun -- Zhou, Dejiang -- Qiu, Liyou -- Lai, Xioamin -- Simon, Meredith -- Shen, Ling -- Kou, Zhongchen -- Wang, Qifan -- Jiang, Liming -- Estep, Jim -- Hunt, Robert -- Clagett, Michelle -- Sehgal, Prabhat K -- Li, Yunyaun -- Zeng, Xuejun -- Morita, Craig T -- Brenner, Michael B -- Letvin, Norman L -- Chen, Zheng W -- HL64560/HL/NHLBI NIH HHS/ -- R01 HL064560/HL/NHLBI NIH HHS/ -- R01 HL064560-04/HL/NHLBI NIH HHS/ -- R01 RR013601/RR/NCRR NIH HHS/ -- R01 RR013601-04/RR/NCRR NIH HHS/ -- RR13601/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2002 Mar 22;295(5563):2255-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tuberculosis Research Unit, Division of Viral Pathogenesis, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11910108" target="_blank"〉PubMed〈/a〉

    Onset of catalytic activity of gold clusters on titania with the appearance of nonmetallic properties (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-09-11
    Description: Gold clusters ranging in diameter from 1 to 6 nanometers have been prepared on single crystalline surfaces of titania in ultrahigh vacuum to investigate the unusual size dependence of the low-temperature catalytic oxidation of carbon monoxide. Scanning tunneling microscopy/spectroscopy (STM/STS) and elevated pressure reaction kinetics measurements show that the structure sensitivity of this reaction on gold clusters supported on titania is related to a quantum size effect with respect to the thickness of the gold islands; islands with two layers of gold are most effective for catalyzing the oxidation of carbon monoxide. These results suggest that supported clusters, in general, may have unusual catalytic properties as one dimension of the cluster becomes smaller than three atomic spacings.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Valden -- Lai -- Goodman -- New York, N.Y. -- Science. 1998 Sep 11;281(5383):1647-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Texas A&M University, College Station, TX 77842-3012, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9733505" target="_blank"〉PubMed〈/a〉
