Synthetic vision and emotion calculation in intelligent virtual human modeling

The virtual human technique already can provide vivid and believable human behaviour in more and more scenarios. Virtual humans are expected to replace real humans in hazardous situations to undertake tests and feed back valuable information. This paper will introduce a virtual human with a novel collision-based synthetic vision, short-term memory model and a capability to implement the emotion calculation and decision making. The virtual character based on this model can ‘see’ what is in his field of view (FOV) and remember those objects. After that, a group of affective computing equations have been introduced. These equations have been implemented into a proposed emotion calculation process to enlighten emotion for virtual intelligent huma

A Test of Monopoly Price Dispersion Under Demand Uncertainty

Dana (2001) developed a model of price dispersion under demand uncertainty. The model predicts that, in the face of uncertain demand and inflexible prices, monopolists maximizes pro fits using ex ante price discrimination. We test the predictions of this model using a unique data set from Major League Baseball (MLB). Estimation of a two-way fixed effects model indicate that ticket price dispersion changes systematically with demand uncertainty in MLB, verifying the predictions of the model.price dispersion; demand uncertainty; sports

Experimental validation of the continuous evolution of flow topology from compressor mode to highly loaded windmill of low-speed axial machines

In aeronautics, onboard axial fans, only used on the ground to cool heat exchangers, can be regarded as potential electrical generation devices when operating at freewindmill in flight. In this case, the appropriate windmilling configuration is the load-controlled one, from which energy recovery is possible. This paper presents a detailed experimental analysis, on a conventional axial compressor, of the continuous local topology evolution on both rotor and stator rows from compressor mode to highly loaded windmill. The objective is to deepen the understanding of windmilling flows and validate experimentally numerical results obtained on a previous paper from the present authors. In this latter, the innovative concept of a dualmachine, meant to reach good performances in both compressor and turbinemodes, was presented and numerically validated. The present paper experimentally confirms the relevance of the new design

The Laboratory Excavation of a Soil Block from Sylvester Manor

This article describes a method of retrieving a large intact soil block from the midden area of the Sylvester Manor site. The soil was micro-stratigraphically excavated within a laboratory setting and analyzed using new approaches to the direct observation of micro-artifact distributions and trace residues on soil surfaces. Low technology analytical methods were selected from fields unrelated to archaeology but readily accessible to workers in a standard archaeological processing laboratory. Preliminary findings are presented in the hope that new low-cost field and laboratory methods can be developed. For example particle mapping of micro-artifacts by direct observation of soil profiles is explored as a possible method of determining the relative dates of bioturbated deposits. A method of visualizing degraded proteins on soil surfaces by ultraviolet fluorescence tagging is presented as a way of collecting soft tissue residues. Lastly, the use of density beads with an aqueous heavy liquid is shown as a promising method for the collection of heavy minerals from soil samples
