    • A method and an apparatus for adaptive data rate selection in a high data rate (HDR) communication system are disclosed. An exemplary HDR communication system defines a set of data rates, at which an access point (AP) may transmit data packets to an access terminal (AT). The transmission data rate is selected to maintain target packet error rate (PER). Each AT monitors signal quality metric of signals received from APs. An AT receiving forward link signals from multiple ATs identifies the AT associated with the highest quality forward link signal. The AT then evaluates the rate at which a tail probability of error is greater than or equal to a target tail probability of error. The AT then generates a prediction of a first data rate at which the PER of packets received from the identified AP will not exceed the target PER, and a prediction of a second data rate at which the PER of packets received from the selected AP will exceed the target PER. The AT uses the values of the first and second data rates to predict probabilities of selecting the first and the second data rates such that a throughput of the HDR system is maximized and the target PER is achieved. The predicted probabilities are then utilized as biases for a method identifying whether the first data rate or the second data rate will be requested from the AP. The disclosed method and apparatus may be extended to the full set of available data rates.
    • 公开了一种在高数据速率(HDR)通信系统中进行自适应数据速率选择的方法和装置。 示例性HDR通信系统定义了一组数据速率,接入点(AP)可在该组数据速率上向接入终端(AT)发送数据分组。 选择传输数据速率以维持目标分组错误率(PER)。 每个AT监视从AP接收的信号的信号质量度量。 从多个AT接收前向链路信号的AT识别与最高质量的前向链路信号相关联的AT。 AT然后评估误差的概率大于或等于目标尾部误差概率的速率。 然后,AT产生对从所识​​别的AP接收的分组的PER不超过目标PER的第一数据速率的预测,以及从所选择的AP接收的分组的PER将超过的第二数据速率的预测 目标PER。 AT使用第一和第二数据速率的值来预测选择第一和第二数据速率的概率,使得HDR系统的吞吐量最大化并且实现目标PER。 然后,将预测概率用作用于识别从AP请求第一数据速率或第二数据速率的方法的偏差。 所公开的方法和装置可以扩展到全部可用数据速率。

    • There is described a circuit electrode formed in an integrated circuit package, which imparts sufficient bonding strength to a soldered section and prevents oxidation of the surface of an Ni—P film without fail. A circuit electrode to be electrically connected to a pattern formed on an organic substrate is formed. An electroless high-concentration Ni—P plating film containing phosphorous at a concentration of 7 to 12 wt. % is formed to a thickness of 3 to 10 &mgr;m so as to cover predetermined portions of the pattern. An electroless low-concentration Ni—P plating film containing phosphorous at a concentration of 3 wt. % or less is formed to a thickness of 0.5 to 10 &mgr;m so as to cover the electroless high-concentration Ni—P plating film. An electroless gold plating film is formed, as an oxidation prevention film, to a thickness of 0.05 to 0.5 &mgr;m so as to cover the surface of the electroless low-concentration Ni—P plating film.

    • Described is estimating whether an online search query is a news-related query, and if so, outputting news-related results in association with other search results returned in response to the query. The query is processed into features, including by accessing corpora that corresponds to relatively current events, e.g., recently crawled from news and blog articles. A corpus of static reference data, such as an online encyclopedia, may be used to help determine whether the query is less likely to be about current events. Features include frequency-related data and context-related data corresponding to frequency and context information maintained in the corpora. Additional features may be obtained by processing text of the query itself, e.g., “query-only” features.
    • 描述了估计在线搜索查询是否是新闻相关查询,如果是,则输出与响应于该查询返回的其他搜索结果相关联的新闻相关结果。 该查询被处理成特征,包括通过访问对应于相对当前事件的语料库,例如最近从新闻和博客文章中爬行。 可以使用诸如在线百科全书的静态参考数据的语料库来帮助确定查询是否不太可能关于当前事件。 特征包括频率相关数据和对应于语料库中维护的频率和上下文信息的上下文相关数据。 可以通过处理查询本身的文本,例如“仅查询”特征来获得附加特征。
