The lightweight design of railway vehicle components using fiber reinforced polymers (FRPs) has become a research hotspot due to the strong need for energy saving and environmental protection. This paper aims evaluate impact damage behavior carbon (CFRP) protection suspender, which is component on vehicles prevent falling joist bolster from touching rails avoid derailment trains. A finite eleme...

We study the starting resources of start-ups, which develop and market new products or services based upon a proprietary technology or skill. We define these companies as research-based start-ups (RBSUs). We look at how technological, financial and human resources at founding cluster together to form different starting resource configurations. Using a unique hand-collected dataset of RBSUs in B...

This paper describes the kinematics and muscle activity associated with the standard sit-up, as a first step in the investigation of complex motor coordination. Eight normal human subjects lay on a force table and performed at least 15 sit-ups, with the arms across the chest and the legs straight and unconstrained. Several subjects also performed sit-ups with an additional weight added to the h...

The decline in religious identification and corresponding increase in the unaffiliated has been one of the most important religious changes in the United Kingdom (UK). The emergence of the “religious nones” is the most obvious sign of continuing secularization and the declining social and cultural relevance of religion. Yet while the religiously-unaffiliated often form the plurality — if not so...

In this paper, an open framework based smart energy storage system (ESS) profile for photovoltaic (PV)-ESS and uninterruptible power supply (UPS)-ESS is proposed and designed. An open framework based smart ESS is designed and developed for unifying the different interfaces among manufacturers. The smart ESS operates under the profile which provides the specifications of peripheral devices such ...

Abstract This paper presents a study of compressed thin-walled composite columns with an open cross-section. The tested specimens top-hat cross-section were made CFRP material. Two arrangements layers [0/-45/45/90]s and [90/0/90/0]s compared. focuses on the buckling phenomenon determination critical loads structure. It includes both numerical analyses using finite element method (FEM) validatio...

The thermal buckling response of square plates with variable angle tows under simply supported conditions is modeled numerically. path tow as a function lateral location. classical lamination theory utilizes fiber paths to calculate loads and stiffness matrices. Using Kirchhoff plate finite element theory, the global material matrix geometric are obtained. By using these matrices, eigenvalues o...
