The Interactive Learning Wall is a Windows/PC-based virtual blackboard system that can be controlled remotely by a classroom instructor and/or students. A laser pointer used by the instructor emulates mouse actions on a computer projection screen. An inexpensive video camera sends each projected frame to a video capture card in the computer; our software detects the bright laser spot, moves a s...

BACKGROUND Numerous physical exercises trigger positive changes in affect after relatively short workouts. Spinning, also known as indoor-cycling, is a very popular form of exercise, especially among women, but its impact on affect have not been examined to date. AIMS The purpose of the current work was to investigate the possible benefits of spinning on affect in self-controlled and in instr...

in this paper, an intelligent control strategy based on combination of the “flatness based control technique” and the “perturbation and observation (p&o;) mppt algorithm” is developed and investigated to control a hybrid electric energy source (heps). this ehps is composed of a fuel cell system (fc) and a solar panel (sp), as the main source and a supercapacitor bank (sc), as the auxiliary sour...

The spin states of iron(ii) complexes 1-bpp derivatives bearing tether group substituents are controlled by the electronic properties linker functional (carboxamide, in this example).

Two groups of children, a pragmatically impaired (PI) group and a group of language-normal (LN) age-matched peers, were compared by use of a referential communication task. Experimenter and child both played the roles of listener and instructor during the task and, in addition, the experimenter sometimes failed to give adequate information when in the role of instructor. Lexical content and str...
