This paper describes the development of a novel humanoid robot foot/ankle based on an orientation Parallel Kinematic Mechanism for intelligent and flexible control. With three identical Universal-Prismatic-Spherical prismatic-actuated limbs and a central Universal-Revolute passive limb, the PKM can perform three degrees of freedom rotation motions. In order to enable the humanoid robot safely t...

Abstract Concrete mix design is the methodology for mixing binder, aggregate and water to achieve required physical, mechanical, thermal properties. In particular, physical properties depend on volume fraction of each element in concrete recipe. this study we considered cement mortar, complying with ASTM C105, as reference binder silica sand aggregate. The mortar was denser high conductivity co...

Cold in-place recycling (CIR) has become an attractive method for rehabilitating asphalt roads that have good subgrade support and are suffering distress related to nonstructural aging and cracking of the pavement layer. Although CIR is widely used, its use could be expanded if its performance were more predictable. Transportation officials have observed roads that were recycled under similar c...

This study is the development of a usability test plan for implementation of an Enhanced 911 Computer Aided Dispatch (CAD) system by emergency response dispatch centers. Enhanced 911 system technologies will allow emergency response personnel to locate cellular 911 callers in distress by pinpointing the latitude and longitude of their location, and mapping it through the use of a Geographic Inf...

This paper seeks to conceptualise a new approach to the identification of the factors influencing the adoption of a political risk assessment (PRA) function. The research population will comprise a convenience sample of Czech international firms. The information whether or not a firm has set up a PRA function will be obtained via a questionnaire survey. By making use of firm value maximization ...

Objective: to examine the underlying mechanisms of adults’ intended caregiving responses to cry sounds in a behavioral genetic design and to investigate the role of cry pitch and perceived urgency in sensitive and harsh caregiving responses. Methods: the sample consisted of 184 adult twin pairs (18-69 years), including males and females, parents and nonparents. in an experimental design we pres...
