PROCESS FOR PRODUCTION OF CHLORINE DIOXIDE

A process for production of chlorine dioxide which is substantially free of by product chlorine. Chlorinedioxide is produced from an alkali metal chlorate, a mineral acid and a reducing agent such as methanol in a reaction medium maintained at an acid normality of less than 9 and with a high chlorate molarity. The process is carried out in the substantial absence of additional chloride ion being fed to the process. It has been found that increasing the chlorate concentration at a given acid normality reduces the amount of chloride in the reaction medium thus reducing the amount of chlorine by-product. The process is carried out in a vessel operated under subatmospheric pressure, whereby water is evaporated and withdrawn together with chlorine dioxide and the alkali metal salt of the mineral acid is crystallized within the reaction vessel and withdrawn therefrom. According to the invention, high production rates with high efficiency of chlorine dioxide can be achieved while producing essentially ...

Method and system for uneven distribution of data

A method for BLER management of radio bearers for TCP traffic is described. The method helps TCP to accelerate during its initial slow start phase or during congestion control. A BLER target management method improves TCP performance under efficient radio resource utilization. The BLER target is set low to help TCP to accelerate until the maximum bit rate of the radio bearer has been reached. Then the BLER target is set to a high value. The low BLER value reduces the number of radio link retransmissions and, hence, reduces the end-to-end RTT.

Fremgangsmate og system for ujevn datadistribuering

Det beskrives en fremgangsmåte for BLER-behandling av radiobærere for TCP-trafikk. Fremgangsmåten hjelper TCP å akselerere under sin initiale trege startfase eller under opphopningskontroll. En fremgangsmåte for BLER-målbehandling forbedrer TCP-ytelsen under effektiv radioressursanvendelse. BLER-målet blir satt lavt for å hjelpe TCP å akselerere helt til den maksimale bitraten for radiobæreren har blitt nådd. Deretter blir BLER-målet satt til en høy verdi. Den lave BLER-verdien reduserer antallet radiolinkresendinger og derfor reduserer ende-til-ende RTT.

Fremgangsmåte og system for å styre overføringseffekt for dataoverføring i et trådløst kommunikasjonssystem.

Det beskrives en fremgangsmåte for BLER-behandling av radiobærere for TCP-trafikk. Fremgangsmåten hjelper TCP å akselerere under sin initiale trege startfase eller under opphopningskontroll. En fremgangsmåte for BLER-målbehandling forbedrer TCP-ytelsen under effektiv radioressursanvendelse. BLER-målet blir satt lavt for å hjelpe TCP å akselerere helt til den maksimale bitraten for radiobæreren har blitt nådd. Deretter blir BLER-målet satt til en høy verdi. Den lave BLER-verdien reduserer antallet radiolinkresendinger og derfor reduserer ende-til-ende RTT.

Method and system for uneven distribution of data

A method for BLER management of radio bearers for TCP traffic is described. The method helps TCP to accelerate during its initial slow start phase or during congestion control. A BLER target management method improves TCP performance under efficient radio resource utilization. The BLER target is set low to help TCP to accelerate until the maximum bit rate of the radio bearer has been reached. Then the BLER target is set to a high value. The low BLER value reduces the number of radio link retransmissions and, hence, reduces the end-to-end RTT.

Core network processing load reduction

A cellular radio communications network includes a core network with a core network node coupled to a radio access network (RAN) associated with a first radio access technology for communicating with mobile radio terminals. The RAN includes multiple RAN nodes. Each mobile radio terminal has an associated access class for accessing service from the cellular radio communications network. The core network node detects an overload condition and sends an overload message to the RAN nodes that includes information for reducing the overload condition. Each of the RAN nodes receives the overload message and determines whether an access class restriction should be implemented to reduce the number of mobile radio terminals permitted to access the cellular radio communications network. If so, the RAN node determines one or more access classes of mobile radio terminals to be restricted based on the information in the overload message. Information relating to the one or more restricted access classes is transmitted in an area associated with the RAN node so that the mobile terminals of a restricted access class are prohibited from accessing the cellular radio communications network.

The reference eye tracking data is generated by the eye tracking system based on sensor data obtained by the second eye tracking sensor at the time instance. The method comprises training (303) the eye tracking model based on the sensor data obtained by the first eye tracking sensor at the time instance and the generated reference eye tracking data.

Method of sharing a mobile telecommunication network with restricted access and telecommunication network implementing the method

The invention relates to a method of sharing a mobile telecommunication network with restricted cell access in non-shared cells and such a telecommunication system. The intended use of the invention is to make it technically feasible to differentiate radio coverage between partners sharing a common third generation, e.g. WCDMA, network in areas where expanded coverage results in non-shared cells. The present invention proposes to use the cell access classes. A unique subset of the first ten access classes is allocated to each sharing partner. Each operator then assigns the given set of access classes among its subscribers. In areas (3A, 3B) where only subscribers of one of the sharing partners should have access to the radio network, the cell's access restriction is set to only allow customers from one of the uniquely assigned sets of access classes, i.e. the ones corresponding to the sharing partner.
