This interactive demo features MIXER, a Virtual Learning Environment (VLE) consisting of synthetic characters representing the various actors in a scenario group difference scenario. MIXER creates virtual dramas by using interactive narrative with those characters. The goal is to enable children to identify social rule differences, by interacting with one of the characters to which they become ...

In this paper, the control over the second gate voltage in a dual-gate FET resistive mixer is employed for amplitude remodulating the response signal in a retrodirective array. A resistive mixer is integrated with an aperture coupled square patch, and a data signal voltage, Vg2s(t), is appropriately conceived in order to control the magnitude of the device time-varying output conductance. Measu...

We report on the first THz balanced mixer/upconverter using a Schottky diode MMIC chip. Using an optically pumped laser at 1562 GHz as an LO source with a coupled power of about 1 mW, and 1 mW input at an IF frequency of 10 GHz, we obtained a sideband output power of 23 uW (sum of two sidebands). As a mixer, at an LO of 1621 GHz, we obtain a conversion loss of 12.4 dB DSB and a noise temperatur...

A few years ago, the process of selecting a mixer for most applications was straightforward. When increased demand required an increase in production, process engineers were naturally inclined to choose the type of mixer that had worked before in the same application. When they began talking to equipment manufacturers, their questions focused on capacity, auxiliary equipment, projected delivery...

This paper discusses the design and evaluation of the system MIXER (Moderating Interactions for Cross-Cultural Empathic Relationships), which applies a novel approach to the education of children in cultural sensitivity. MIXER incorporates intelligent affective and interactive characters, including a model of a Theory of Mind mechanism, in a simulated virtual world. We discuss the relevant peda...

The mixer chain on a graph G is the following Markov chain. Place tiles on the vertices of G, each tile labeled by its corresponding vertex. A “mixer” moves randomly on the graph, at each step either moving to a randomly chosen neighbor, or swapping the tile at its current position with some randomly chosen adjacent tile. We study the mixer chain on Z, and show that at time t the expected dista...

We have developed a microfluidic mixer for studying protein folding and other reactions with a mixing time of 8 mus and sample consumption of femtomoles. This device enables us to access conformational changes under conditions far from equilibrium and at previously inaccessible time scales. In this paper, we discuss the design and optimization of the mixer using modeling of convective diffusion...

In microfluidics mixing of different fluids is a highly non-trivial task due to the absence of turbulence. The dominant process allowing mixing at low Reynolds number is therefore diffusion, thus rendering mixing in plain channels very inefficient. Recently, passive chaotic micromixers such as the staggered herringbone mixer were developed, allowing efficient mixing of fluids by repeated stretc...

In this paper the selection of a mixer topology for a multi-standard, non-concurrent front-end is presented. The front-end is designed for Digital Enhanced Cordless Telephone (DECT) systems and systems for wireless communications, which operate in the 2.4 GHz Industrial Scientific Medical (ISM) band (like Bluetooth or DECT alike systems at 2.4 GHz). Three mixer topologies are presented and eval...

Accurately identifying patient’s status through medical images plays an important role in diagnosis and treatment. Artificial intelligence (AI), especially the deep learning, has achieved great success many fields. However, more reliable AI model is needed image guided therapy. To achieve this goal, developing a balanced, safe robust with unified framework desirable. In study, new termed as aut...
