A new internal array structure, called a double-array, implementing a trie structure is presented. The double-array combines the fast access of a matrix form with the compactness of a list form. The algorithms for retrieval, insertion and deletion are introduced through examples. Although insertion is rather slow, it is still practical, and both the deletion and the retrieval time can be improv...

This article explores experimental methods in sociology that are used to address sensitive questions. Sensitive questions those involve socially stigmatized or taboo subjects, such as illegal activities, personal beliefs, and sexual behavior. The use of traditional survey investigate may lead response bias social desirability bias. To overcome these limitations, scientists have developed innova...

BACKGROUND The list experiment is a promising measurement tool for eliciting truthful responses to stigmatized or sensitive health behaviors. However, investigators may be hesitant to adopt the method due to previously untestable assumptions and the perceived inability to conduct multivariable analysis. With a recently developed statistical test that can detect the presence of a design effect -...

The knapsack problems are a classic NP-hard problem in the combinational optimization. Inspired by the conclusion of the cognitive psychology about the human memory system, a Tabu Search method based on Double Tabu-List (DTL-TS) has been proposed to solve it. With the addition of the search strategy of intensification and diversification, the excellent experiment results have been gotten. Compa...

If A > B, and B > C, it follows logically that A > C. The process of reaching that conclusion is called transitive inference (TI). Several mechanisms have been offered to explain transitive performance. Scanning models claim that the list is scanned from the ends of the list inward until a match is found. Positional discrimination models claim that positional uncertainty accounts for accuracy a...

As a new joint source-channel coding scheme, the double polar (D-Polar) codes have been proposed recently. In this letter, novel decoder, namely successive cancellation list (J-SCL) is to improve decoding performance of D-Polar codes. We merge trellis source code and that channel construct compound trellis. trellis, variable nodes corresponding information bits representing high-entropy are mer...
