This paper introduces a time-variant reverberation algorithm as an extension of the feedback delay network (FDN). By modulating the feedback matrix nearly continuously over time, a complex pattern of concurrent amplitude modulations of the feedback paths evolves. Due to its complexity, the modulation produces less likely perceivable artifacts and the time-variation helps to increase the livelin...

A self-report instrument to measure multiple mood states was constructed. Six hundred and forty-eight Japanese affect adjectives were collected and divided into two lists. Japanese undergraduates totaling 1,254 rated each adjective in the list on a 4-point intensity scale to assess their momentary mood states. Factor analyses revealed 131 items with high loading on extracted major factors. The ...

This study investigated the relationship between affective properties of stimuli and their retention. Thirty sentences describing various scenes were chosen as stimuli to elicit affects which are experienced in daily life. Ninety undergraduates rated each sentence on the following eight dimensions: anxiety, hostility, boredom, liveliness, calmness, friendliness, concentration, and surprise. One...

of the displayed information, the importance and the degree of certainty of the information should be communicated along with the main content. The proposed intent expression system aims at conveying this additional information using the eye robot system. Eye motions are represented as the states in a pleasure-arousal space model. Changes in the model state are calculated by fuzzy inference acc...

This paper investigates how the language of instruction in Dutch higher education (Dutch versus English) affects speech production by L1 Dutch-speaking lecturers. In a pairwise design, three young lecturers that were highly proficient English gave two comparable lectures each (L1 and L2 English). Results show consistently given at slightly syllabic articulation rates filled pauses shorter occur...

We propose new criteria for the classi cation of systems for database cooperation, based on the nature of the component databases. In fact, the traditional criteria | heterogeneity, distribution, and autonomy| are often constraints for the design process, rather than design parameters. In this case, other features of the component databases should be addressed. We claim that a more useful class...

In 1974, Hoots classified historical philosophies of elementary-school industrial arts (ESIA) into four categories: subject matter, in which children would study technology and its social impacts (e.g., Gilbert, 1966); arts and crafts, consisting of what Hoots (1974) called “concrete manipulative activities” (p. 225); method of teaching, in which industrial arts delivered, reinforced, and enric...

Speech is one component of most synthetic characters. It is often assumed that the most important objective for such characters is that they should be ‘life-like’, ‘natural’ and ‘believable’. This paper suggests that this is inappropriate and that a better quality is one which we call liveliness. This concept and many of the ideas behind it derive from the theatre. One of the objectives of this...

This article proposes that in the future, P-E fit studies should use objective (as opposed to subjective) measures of the environment, such as the group size, in order to avoid numerous methodological problems. Several hypotheses were formulated in this article. Group size was hypothesised to moderate the following relationships: apprehension, sensitivity, social boldness and extroversion with ...

Today's public Wireless LANs are restricted to hotspots. With the current technology, providers can only target a small audience and in turn charge high prices for their service to generate revenue. Also, providers cannot react appropriately to dynamic changes in the demand. With multi-hop cellular networks the coverage area can be increased and the installation costs as well as investment risk...
