Wavelet transform is a powerful instrument in catching zero-dimensional singularities. Ridgelets are a powerful instrument in catching and representing monodimensional singularities in bidimensional space. In this paper we propose a hybrid video coder scheme using ridgelet transform for the first approximation of line-edge singularities in displaced frame difference images. We demonstrate the p...

China became the second-largest economy behind the USA in 2010. While there is quite some macroeconomic research documenting the technological catching-up of China as a nation, there is only little research studying how individual Chinese firms are catching up. This paper draws on the open innovation perspective to explore how Chinese firms improve their innovative performance. Our empirical an...

According to the action-specific account of perception, a perceiver's ability to act influences how the environment is perceived. For example, in a computer-based task, participants perceive fish as moving faster when they use a smaller net, and are thus less effective at catching the fish (Witt & Sugovic, 2013a). Here, we examined the degree to which attention may influence perceptual judgment...

Factors shaping joint coordination during multijoint movements were studied using a one-handed ball-catching task. Typically developing (TD) boys between 9 and 12 yr of age, at which catching becomes consistently successful, and boys with developmental coordination disorder (DCD) of the same age participated in the study. The arm was initially stretched down. Catching was performed by flexing t...

We tested the performance of ten commercial mosquito traps with varying attractive features, against three CDC traps (an unlit model 512, an incandescently lit model 512, and a UV lit model 1212) as well as simple sticky paper, for their ability to attract and capture Phlebotomus papatasi in Israel. The commercial traps tested were the Sentinel 360, the Combo Trap, the Mega Catch Premier, the B...

A majority of the countries of SEE are so-called ‘catching-up’ economies. 1 This basically means that their enterprises operate largely behind the technological frontier, by using the best available foreign technologies and by competing on the basis of production capability. However, catching up is not a process of mere imitation; it requires adaptation and innovation (Fagerberg and...

I N T R O D U C T I O N In Alice's Adventures in Wonderland by Lewis Carrel many of Alice's friends have names that consists of two words, for example: the March Hare, the Mock Turtle, and the Cheshire Cat. '['he individual words in these combinations, if we ignore capitalisation, might be quite common. Individual words usually mean different things when they am free. l:or example, in "The Marc...

The paper presents a biologically-inspired multi-level neural-schema architecture for prey catching and predator avoidance in single and multiple autonomous robotic systems. The architecture is inspired on anuran (frogs and toads) neuroethological studies and wolf pack group behaviors. The single robot architecture exploits visuomotor coordination models developed to explain anuran behavior in ...

Robot hand-eye coordination has recently enjoyed much attention. Previous research at MIT has examined combining vision and manipulation applied to the task of tracking and catching tossed balls in controlled environments. Building upon the foundations of this past research, this paper presents work which incorporates a new active vision system which requires a minimally controlled environment,...

This paper studies the possibility that a “catching-up-with-the-Joneses” effect can cause indeterminacy. In an otherwise standard growth model with an external past consumption habit, we analytically show that a catching-up-with-the-Joneses effect is a possible source of indeterminacy. In the quantitative investigation, we use a calibrated version of the model with a CES utility and find that i...
