摘要:
To create a network that connects a plurality of wireless communication systems to create optimal systems for various environments, and that seamlessly integrates the resulting systems together in order to provide more efficient and advanced service in general. A network system that can seamlessly integrate wireless communication systems employs a heterogeneous network architecture with at least four building blocks, including a mobile host 40, a wireless access network 41, a common core network 42, and an external network 43.

A viewing user is provided with social advertisements when accessing content associated with a social networking system. A social advertisement can include a candidate advertisement and an associated social story. Candidate advertisements are advertisements provided by one or more advertisers, where the advertisements each specify a relationship between their advertising content and one or more social networking objects. To identify social stories associated with the candidate advertisements, the social networking system identifies other users associated with the viewing user who has interacted with social networking objects that are related to candidate advertisements. Additionally, the social networking system identifies the one or more interactions between the other users and the one or more objects as a social story. The social networking system selects a candidate advertisement and combines it with a social story to create a social advertisement and sends the social advertisement for display to the viewing user.

An energy-saving optimized control system for a chiller plant room comprises an industry control computer, a flow sensor, a temperature sensor, an outdoor temperature and humidity sensor, a three-phase active power transmitter, a water pump variable speed driver and a cooling tower fan variable speed driver, which are respectively connected with a programmable controller, wherein the programmable controller communicates with the industrial control computer through an industrial Ethernet; and an RS485 communication interface module is connected with chillers and communicates with the industrial control computer through a ModBus protocol. An energy-saving optimized control method for a chiller plant room is also provided. By establishing a mathematical model of the relationship between the energy consumption and operation parameters of each equipment in the refrigeration plant room and combining the real-time cooling loads and weather parameters, the operating state of each equipment is adjusted so as to reach the lowest operating energy consumption of the whole chiller plant room under the premise of meeting the cooling loads.

It is an object of the present invention to provide a sulfonic acid group-containing polymer and a sulfonic acid group-containing aromatic compound, which have excellent proton conductivity even under the low humidification condition, are excellent in mechanical strength and chemical stability and, moreover, can attain high output and excellent physical durability when processed into a solid polymer fuel cell, as well as a polymer electrolyte material, a polymer electrolyte molded product and a solid polymer fuel cell respectively using the same. The sulfonic acid group-containing polymer of the present invention is a sulfonic acid group-containing polymer comprising a constituent unit containing a sulfonic acid group (A1), and a constituent unit not containing a sulfonic acid group (A2), wherein the polymer contains a constituent unit having a specified structure as at least one constituent unit containing a sulfonic acid group (A1) at 25 mol % or more based on a sum of the constituent unit containing a sulfonic acid group (A1). Further, the polymer electrolyte material, polymer electrolyte molded product and solid polymer fuel cell of the present invention are constituted using such a sulfonic acid group-containing polymer.

A social networking system provides access to personas comprising information, for example, web pages describing users or entities. The information may be suggested by the social networking system or requested by the user, for example, via search. The social networking system authenticates the personas so that only authentic personas are suggested to users or returned when a user is searching for information. The authenticity of a persona is determined based on the connections and/or likes coming from other personas, user accounts, or other entities represented within the social networking system that have been previously authenticated. The authenticity of the person is also determined based on external links to the persona, for example, external websites referring to the persona or the rate at which external systems such as search engines direct web traffic to the persona.
摘要:
A Fe—Co hybrid catalyst for oxygen reaction reduction was prepared by a two part process. The first part involves reacting an ethyleneamine with a cobalt-containing precursor to form a cobalt-containing complex, combining the cobalt-containing complex with an electroconductive carbon supporting material, heating the cobalt-containing complex and carbon supporting material under conditions suitable to convert the cobalt-containing complex and carbon supporting material into a cobalt-containing catalyst support. The second part of the process involves polymerizing an aniline in the presence of said cobalt-containing catalyst support and an iron-containing compound under conditions suitable to form a supported, cobalt-containing, iron-bound polyaniline species, and subjecting said supported, cobalt-containing, iron bound polyaniline species to conditions suitable for producing a Fe—Co hybrid catalyst.

According to one embodiment, a method for transmission/reception contention resolution in D2D communication is provided. The method includes detecting, at a device-to-device (D2D) node, re-usable cellular resources based on the scheduling information. The method also includes receiving related information from another D2D node identifying the re-usable cellular resources for the another D2D node, and identifying common and different re-usable cellular resources between the D2D node and the another D2D node. The method also includes receiving updated scheduling information, and determining, from the detected re-usable cellular resources, whether there is a simultaneous transmission/reception contention. When it is determined that there is a simultaneous transmission/reception contention, the method includes resolving the contention by dynamically selecting a direction of communication based on a preconfigured decision criteria, wherein the direction of communication is one of transmission or reception.

Various embodiments pertain to serving a number of advertisements in view of browser information and a user's interaction with the web page containing the advertisements. In at least some embodiments, information regarding the size of a browser user interface in which a browser renders the web page, visibility of the browser user interface, or status of the browser can be obtained and utilized to determine a number of slots available for advertisements. For example, if a browser is being used to render a web page on a screen of a mobile device, fewer advertisements can be served compared to when the same web page is rendered by a browser on a desktop monitor. In some embodiments, page script can be used to obtain information regarding the size of a browser user interface, visibility of the browser user interface, or status of the browser.
摘要:
A mold and a method for integrally manufacturing a functional cored slab and a solid slab with a polygonal grid honeycomb structure. The mold for manufacturing the cored slab comprises a female mold and multiple male molds which are provided in the female mold. The male molds include polygonal cylinders capable of melting, dissolving, or vaporizing. A clearance exists between at least one pair of adjacent polygonal cylinders. The mold for manufacturing the solid slab is provided with a male mold main-body of polygonal cylinders which share the same shape and amount as the polygonal grids. The male mold main-body, which is made of one of the functional materials including sound insulating materials, flame retardant materials, and thermal insulating materials, is located in the frame-like female mold having a bottom plate. Clearances are provided between the adjacent male mold bodies. A casting method is adopted when manufacturing the slabs.
