For research into bipedal walking machines, autonomous operation is an important issue. The key engineering problem is to keep the weight of the actuation system small enough. For our 2D prototype MIKE, we solve this problem by applying pneumatic McKibben actuators on a passive dynamic biped design. In this paper we present the design and construction of MIKE and elaborate on the most crucial s...

Objectives: Specific language impaired children, despite being normal in cognitive and neurological characteristics, and also normal levels of hearing, experience multiple problems in syntax comprehension. This study compared the passive comprehension as one of Syntactic Structures in Persian-speaking typically developing children and Specific language impaired children. Methods: 10 children w...

Energy demand for active mechanical space cooling is projected to double by 2050. Wider adoption of passive systems can help reduce demand. However, familiarity with these remains low, and innovation in the field constrained due a lack cost-effective, accessible performance evaluation methods. This paper reports design, construction, commissioning an affordable, self-contained environmental tes...

The State of Florida has developed a draft radon standard for new residential construction. A study was conducted to evaluate the effectiveness of the standard's features in controlling radon entry in new houses built over relatively high radon potential soils. Special attention was given to foundation preparations and slab placements to insure that the draft standard requirements were being me...

Two generic classes of chaotic oscillators comprising four different configurations are constructed. The proposed structures are based on the simplest possible abstract models of generic second-order RC sinusoidal oscillators that satisfy the basic condition for oscillation and the frequency of oscillation formulas. By linking these sinusoidal oscillator engines to simple passive first-order or...

The State of Florida has a draft radon standard for new construction. This study was conducted to evaluate the effectiveness of two slab types (monolithic and slab-in-stem wall) in retarding radon entry in new houses built in accordance with the proposed standard over high radon potential soils. Fourteen houses were monitored during their construction on sites whose soil gas radon concentration...
