Abstract:
Conductive cement-based compositions exhibiting both good electrical conductivity and mechanical strength have been obtained by ensuring proper dispersion of conductive phase within the composition. The content of the ingredients depends on the preparation method, for instance conventional mixing or slurry infiltration, and on the type of the composition, i.e. conductive paste, mortar or concrete. The broad content ranges of the conductive composition are:a cement binder,a conductive phase consisting of one or more of the following:conductive fibers in the amount from 0 to 15% by volume of the composition;conductive particles in the amount from 0 to 80% by volume of the composition;water, at the weight ratio relative to cement binder from 0.2 to 0.75,fine agregates at the weight ratio relative to cement binder from 0.0 to 2.0, andcoarse aggregates at the weight ratio relative to cement binder from 0.0 to 2.0,conventional additives or admixtures, and optionally a dispersant.Exemplary compositions obtained according to the invention have a 28-day d.c. resistivity of 0.46-43 .OMEGA.cm and 28-day compressive strength of 35-71 MPa.
Abstract:
The present invention includes searching imagery data in order to identify one or more patterned regions on a semiconductor wafer, generating one or more virtual Fourier filter (VFF) working areas, acquiring an initial set of imagery data from the VFF working areas, defining VFF training blocks within the identified patterned regions of the VFF working areas utilizing the initial set of imagery data, wherein each VFF training block is defined to encompass a portion of the identified patterned region displaying a selected repeating pattern, calculating an initial spectrum for each VFF training block utilizing the initial set of imagery data from the VFF training blocks, and generating a VFF for each training block by identifying frequencies of the initial spectrum having maxima in the frequency domain, wherein the VFF is configured to null the magnitude of the initial spectrum at the frequencies identified to display spectral maxima.
Abstract:
The invention provides a method for transmitting data through mobile communication equipment. The mobile communication equipment has a first communication mode and a second communication mode. In the method, it is first determined whether the mobile communication equipment is required to transmit the data by the first communication mode or the second communication mode, wherein the data conforms to a first format related to the first communication mode. Subsequently, when the mobile communication equipment is required to transmit the data by the second communication mode, the data is adjusted according to a second format related to the second communication mode to generate an adjusted data. The adjusted data is then transmitted by the second communication mode.
Abstract:
A communication control system applicable to a portable communication apparatus and a method thereof are disclosed. The communication control system includes a first communication module, a second communication module, a detector, and a controller. A first wireless signal is sent and received between the first communication module and a first base station via a first communication network. A second wireless signal is sent and received between the second communication module and a second base station via a second communication network. The detector detects the statuses of the first communication module and the second communication module. If one of the communication modules is detected being in communication, the detector triggers the controller to stop the other communication module from using the corresponding communication network.
Abstract:
A method and apparatus are provided for measuring the thickness of a test object. The apparatus includes an eddy current sensor having first and second sensor heads. The sensor heads are positioned to have a predetermined gap therebetween for passage by at least a portion of the test object through the gap. The sensor heads make measurements at given sampling locations on the test object as the test object is moved through the gap. The apparatus also includes a position sensing mechanism to determine positions of the sampling locations on the test object. The apparatus also includes an evaluation circuit in communication with the eddy current sensor and to the position sensing mechanism for determining the thickness of the test object at the sampling locations.
Abstract:
The present invention is to provide a method, which employs a detection control software installed in a dual-mode mobile phone of the GSM network communication system and the low power PHS network communication system, so as to automatically detect the dialing network service area of the best communication rate, when the dual-mode mobile phone enters into a selection mode for automatically switching to the optimized dialing network in a time period, and then dial out via the detected dialing network service area of the best communication rate after a dialing message is received. Thus, the users of the dual-mode mobile phones can enjoy the low communication rate, which will largely reduce the cost of their phone bills.
