Abstract: Methods and system of traffic load balancing between a plurality of Points of Presence (PoP) of a cloud computing infrastructure are described. A first PoP of multiple PoPs of cloud computing infrastructure that provides a cloud computing service receives a packet. The packet includes as a destination address an anycast address advertised by the first PoP for reaching the cloud computing service. The first PoP identifies a network address of a second PoP that is different from the first PoP. The first PoP forwards the packets as an encapsulated packet to the second PoP to be processed in the second PoP according to the cloud computing service.

Abstract: Methods for operating real-time wireless networks enable robust medium access strategies for communicating nodes in the network. A given wireless channel is divided into several sub-carriers, with each node assigned to a subset of sub-carriers. A master wireless node uses different subsets of the sub-carriers to communication with two or more slave wireless nodes simultaneously. The method includes generation of preambles that are robust to interference and multipath conditions. The method also enables communication within a maximum predetermined latency bound.

Abstract: The water retention agents according to the invention are outstandingly suitable as additives in construction chemistry systems and in the development, exploitation and completion of underground mineral oil and natural gas deposits and in deep wells, their effect being particularly advantageous at increased temperatures and because of their lack of influence on the rheological properties of the well slurries.

Abstract: The invention describes amphiphilic polymer compounds which are prepared by a) reacting a di-, tri- or tetraglycidyl compound (A) with an optionally unsaturated reactive component (B) consisting of C8-C28-fatty acid, a C8-C28-alcohol or a secondary C8-C28-amine, and allowing b1) the reaction product from stage a) to react further first with b1?) an aliphatic or aromatic polyisocyanate compound (C) b1?) and optionally then with a polyalkylene oxide compound (D), and b1?) reacting the reaction product from stage b1?) or optionally b1?) with a component (E) which is reactive towards isocyanates and has at least one OH, NH2, NH or SH group, or b2) allowing the reaction product from stage a) to react to completion with the reaction product of component (C) with component (E) and optionally (D) and (C), or b3) allowing the reaction product from stage a) to react to completion with the reaction product from component (C) and component (D) and optionally (C) and optionally the reaction product of component (C) and

Abstract: Methods and apparatuses for selective epitaxial formation of films separately inject reactive species into a CVD chamber. The methods are particularly useful for selective deposition using volatile combinations of precursors and etchants. Formation processes include simultaneous supply of precursors and etchants for selective deposition, or sequential supply for cyclical blanket deposition and selective etching. In either case, precursors and etchants are provided along separate flow paths that intersect in the relatively open reaction space, rather than in more confined upstream locations.

Abstract: The present invention relates to the use of epoxy derivatives which have been prepared by reacting a di-, tri- or tetraglycidyl compound (A) with an optionally unsaturated reactive component (B) consisting of a C8-C28-fatty acid, a C8-C28-alcohol or a secondary C8-C28-amine as additives to cementitious building materials. The epoxy derivatives proposed according to the invention are outstandingly suitable as compositions for preventing or suppressing efflorescence on surfaces of set cementitious building materials and/or for hydrophobing the corresponding cementitious systems. In addition, the cementitious products take up substantially less water owing to the additives proposed according to the invention, with the result that frost damage and rapid rusting of the reinforcing steel can be substantially reduced.

Abstract: The invention relates to carboxylic acid derivatives which are obtained by reacting an unsaturated dicarboxylic acid anhydride (A) with a hydrophobic reactive component (B) that contains at least one group reacting to carboxylic acid anhydrides and has an average molecular weight of 200 to 50,000 Dalton. The inventive carboxylic acid derivatives are excellent as a substance for preventing efflorescences on surfaces of hardened cementitious construction materials and/or hydrophobizing the corresponding cementitious systems. Furthermore, said cementitious products absorb considerably smaller amounts of water as a result of the inventive additives such that frost damage and premature rusting of the reinforcing steel can be significantly reduced.

Abstract: A user is provided with the choice of selecting either a client or a server for providing either local or remote services on a data file, respectively, if both the server and the client have the resources for the desired service. The user may select the client or the server upon requesting a particular operation or service on a data file or may enter pre-selections according to which of the client or the server will be selected for execution of the operation. A client program and a server program for providing the service may be divided into at least two modules and the client and server may be selected for executing the first and second modules.

Abstract: A method and system are provided for managing files which are modified while the contents of the files are being viewed in a browser window in a data processing system. During execution of the browser, if a request to close a window in the browser is received, it is determined whether a file which was displayed in the window was modified since a last save operation for the file. If the file was modified, and the file had not been saved with the modifications, then an indicator of the modified file is included in a modification list with a reference to enable access to the modified file. The modification list is then sent to a user of the file so that the user may select options for saving the modified file, discarding the modifications, or resuming editing of the file. Thus, integrity of file modifications is enhanced.

Abstract: A method for identifying one file in a plurality of files facilitates a user rapidly selecting the file. In an input operation, at least one character that was input by a user is received. In a find file operation, the method compares an input character string that is, or that includes, the at least one character with each individual data file name of a plurality of data file names. The find file operation identifies individual data files names that include a character string that corresponds to, i.e., matches, the input character string. A send to display operation sends at least one of the identified individual data file names to a display unit, which in turn displays the sent information to the user, i.e., suggests an individual data file name to the user. If the user accepts the suggested individual data file name via one input order action forwarded, the selected file is processed as desired by the user.

Abstract: A graphic user interface for entering a new file directory on a computer uses a single file navigation dialogue window that displays a user selectable list of predetermined default directories, user-defined directories, and previously used directories. The user uses a single action to navigate among the directories listed in the single file navigation window.
