A mechanical device especially designed for the application of low-level posttensioning forces to glass fiber reinforced polymer (GFRP) bars was developed at the University of Missouri-Rolla. Some of the advantageous features of this device are that it is simple to assemble and the low-level post-tensioning forces can be applied manually and safely without the need for hydraulic jacks or heavy ...

Battery charging and State-Of-Charge management is one of the main relevant issues for developing mobile autonomous robots. This paper presents a complete development of an battery charger for an autonomous mobile robot and a discussion of SOC estimation models. Initially a charger prototype, based on a HalfBridge DC-DC converter, was developed and tested. Furthermore, the MATLAB SimPowerSystem...

Abstract With the increasingly deepen knowledge on structural dynamic behaviour, nowadays, monumental staircases and their steps are usually designed with high stiffness low mass, obtaining fundamental frequencies, out of interval step frequencies excitable by human walking. However, neglecting structure’s mass can also result in levels impulsive responses. Furthermore, often connection between...

The absence of agreed definitions and metrics for supercomputer RAS obscures meaningful discussion of the issues involved and hinders their solution. This paper seeks to foster a common basis for communication about supercomputer RAS, by proposing a system state model, definitions, and measurements. These are modeled after the SEMI-E10 [1] specification which is widely used in the semiconductor...

The construction of tall and slender buildings has seen recent growth in many cities around the world. Tall are susceptible to dynamic excitation under wind effects which typically govern structural design for strength, stability, serviceability. This paper presents state art analysis against effects. Structural criteria discussed detail, with serviceability relating occupant comfort noted as b...

in this paper, evaluation of torsional stiffness in beam and slab bridge deck elements is presented. a beam and slab bridge decks structurally behave as a grillage. a grillage has an efficient transverse load distribution due to transverse asymmetric load. in the case of bridge deck without transverse beams in the span, transverse load distribution depends on the torsional stiffness of longitud...
