For recognizing two-width barcodes having N bars and N spaces, a first class (cluster) A of wide bars or spaces contains n elements Array [1] to Array [n], and a second class (cluster) B of narrow bars or spaces contains N−n elements Array [n+1] to Array [N] are created. Looping n times where n=1 to N−1, a mean value μA to of class A and a mean value μB of class B are calculated, a between-class difference D=μA−μB is calculated, a value of n when D achieves a maximum value is recorded, and if n=M when D achieves the maximum value, then the N bars or spaces are recognized as a two-width barcode; otherwise, the N bars or spaces are determined as not a two-width barcode.

The present invention relates to the use of LCOs in initiating earlier flowering, increased number of buds and flower buds and earlier fruit development in non legume and legume plants, as compared to flowering and fruit development under conditions without use of LCOs, and the enhancement of plant growth and yield associated therewith; to compositions comprising an effective amount of at least one LCO and agriculturally acceptable carriers, associated with earlier flowering, increased bud and flower numbers and earlier initiation of fruit development as compared to conditions without use of LCOs, and with increased growth and plant yield; and to methods using LCOs and compositions of one or more LCOs and agriculturally acceptable carriers, associated with earlier flowering initiation, increased bud and flower numbers and earlier fruit development in both legume and non-legume crop plants as compared to conditions without use of LCOs and associated enhancement of growth and yield.
摘要:
The invention relates to a cognitive SIMO network access method based on cooperative relay, wherein a cognitive base station collects channel responses in a network and judges whether the cognitive users can cooperate with a primary user to achieve the target transmission rate required by the primary user or not, if so, a cognitive SIMO network is accessible to a frequency band licensed to the primary user; otherwise, the cognitive SIMO network is non-accessible. The access method can enable a plurality of the cognitive users and the primary user to simultaneously use the same licensed spectrum in the same geographical position, on the premise of ensuring the target transmission rate of the primary user, and further improve the utilization efficiency of the spectrum as far as possible. As the access method is based on cooperative communication, the nearer the distance from the cognitive network to the primary network is, the greater the network throughput can be achieved; and furthermore, a large-range network coverage can be realized, so the deficiencies in the existing cognitive radio access ways are made up.

Technologies for a human computation framework suitable for answering common sense questions that are difficult for computers to answer but easy for humans to answer. The technologies support solving general common sense problems without a priori knowledge of the problems; support for determining whether an answer is from a bot or human so as to screen out spurious answers from bots; support for distilling answers collected from human users to ensure high quality solutions to the questions asked; and support for preventing malicious elements in or out of the system from attacking other system elements or contaminating the solutions produced by the system, and preventing users from being compensated without contributing answers.

A precursor solution for producing a semiconductor includes at least one of an alkali metal or an alkali metal compound dissolved in a solvent, and a metal chalcogenide dissolved in the solvent. A method of producing a precursor solution for a semiconductor includes preparing a first precursor solution that has at least one of an alkali metal or an alkali metal compound dissolved in a first solvent, preparing a second precursor solution that has a metal chalcogenide dissolved in a second solvent, and combining the first and second precursor solutions to obtain the precursor solution for producing the semiconductor. A method of producing a semiconductor device includes providing a precursor solution for producing a semiconductor layer on a substructure, and forming a layer of the precursor solution on the substructure. The precursor solution includes at least one of an alkali metal or an alkali metal compound dissolved in a solvent, and a metal chalcogenide dissolved in the solvent.
摘要:
Mobile device assisted secure computer network communications embodiments are presented that employ a mobile device (e.g., a mobile phone, personal digital assistant (PDA), and the like) to assist in user authentication. In general, this is accomplished by having a user enter a password into a client computer which is in contact with a server associated with a secure Web site. This password is integrated with a secret value, which is generated in real time by the mobile device. The secret value is bound to both the mobile device's hardware and the secure Web site being accessed, such that it is unique to both. In this way, a different secret value is generated for each secure Web site accessed, and another user cannot impersonate the user and log into a secure Web site unless he or she knows the password and possesses the user's mobile device simultaneously.
摘要:
An encoder employs a trellis coded quantization (TCQ) unit and a compression unit. The TCQ uses a set of polynomials that have been selected to maximize granular gain. The TCQ unit operates on a block of samples from a source. The compression unit compresses bit planes of the TCQ output, using parity check matrices of corresponding LDPC codes, to obtain corresponding syndromes. The parity check matrices are selected so their compression performance approaches close to the limit for Slepian-Wolf coding. A decoder employs a decoding unit and an estimation unit. The decoding unit decodes the syndromes using side information to produce an estimate for the TCQ output. The side information is correlated with the source. The estimation unit estimates the block of source samples using the estimated TCQ output and the side information. Trellis coded vector quantization may be used as an alternative to TCQ.

The present invention relates an antifouling electrocatalytic composite membrane and a membrane reactor. The electrocatalytic composite membrane (3) consists of a substrate and a catalytic coating, wherein the substrate is selected from a conductive substrate or a nonconductive substrate coated with a conductive coating, and the substrate is a porous support having supporting, conducting and separating functions. The catalytic coating is supported or coated on the surface and in the pores of the conductive substrate or the conductive coating so as to increase the electrocatalytic activity of the substrate. The membrane reactor provides a trans-membrane pressure as the membrane separation power generated by a pump (7) and dead-end filtration or cross-flow filtration is applied, then the feed liquid permeates through the membrane from one side to the other to achieve the separation of the liquid; meanwhile, an electrocatalytic composite membrane (3) as anode and an auxiliary electrode (4) as cathode are connected to a power supply (1) separately by conducting wires (2) so that an electrolysis apparatus is formed. The electrocatalytic composite membrane (3) has a self-cleaning function and achieves the pollution-free operation during the membrane separation.
