Two-way transducers are ordinary finite two-way automata that are provided with a one-way write-only tape. They perform a word to word transformation. Unlike one-way transducers, no characterization of these objects as such exists so far except for the deterministic case. We study the other particular case where the input and output alphabets are both unary but when the transducer is not necess...

Varieties of multi-modal menu outputs were examined in a real driving situation with respect to efficient system interaction and aspects of safety. An electronic manual served as an exemplary application. The speech output was combined with four different display-versions concerning the timing of the output. The test was based on a within-subject-design. Every subject performed one control cond...

We present a comparative analysis of multi-modal user inputs with speech and pen gestures, together with their semantically equivalent uni-modal (speech only) counterparts. The multimodal interactions are derived from a corpus collected with a Pocket PC emulator in the context of navigation around Beijing. We devise a cross-modality integration methodology that interprets a multi-modal input an...

In recent years some multi-mode pushover procedures taking into account higher mode effects, have been proposed. The responses of considered modes are combined by the quadratic combination rules, while using the elastic modal combination rules in the inelastic phases is not valid. Here, an optimum weighted mode combination method for nonlinear static analysis is presented. Genetic algorithm is ...
