The use of casting CAE (solidification analysis and fluidity analysis) technologies, developed through previous research activities, has enabled, to some extent, a reduction in both shrinkage cavities, through an improved feeding method, as well as misruns and cold shut defects, thanks to an improved runner. On the other hand, however, throughout the entire casting process, the work hours requi...

Combining Mikhail Bakhtin’s concept of the chronotope and Sarah Dillon’s notion palimpsest, essay highlights dialogic relationship between narrative time space in Chicana author Helena María Viramontes’s novel, Their Dogs Came with Them (2007). Set East Los Angeles 1960s 1970s—the heyday urban renewal projects rapid spread freeways—the novel registers geographical displacement constrained socio...

The interpretation of metaphorical utterances often results in the attribution of emergent properties; these are properties which are neither standardly associated with the individual constituents of the utterance in isolation nor derivable by standard rules of semantic composition. For example, an utterance of ‘Robert is a bulldozer’ may be understood as attributing to Robert such properties a...

The hydraulic torque converter is a critical component in high-power tracked vehicles such as bulldozers or bridge machines. Its axial force has significant impact on the reliability and load-carrying capacity of transmission system, which greatly influenced by charging oil conditions. To investigate characteristic its effects, computational fluid dynamics (CFD) method established considering i...

This paper reports on a set of theoretical and experimental investigations into the use of force reflection to enhance the dynamic behavior of human piloted vehicles, especially joystickcontrolled vehicles such as fly-by-wire jets, bulldozers, and powered wheelchairs. Briefly, force reflection is used in the manual controls to cancel the effects of feedthrough dynamics. Feedthrough dynamics ref...

The levels of exposure whole-body vibration (WBV) while performing mechanized soil preparation operations are concerning due to the time operators at their work stations, adverse terrain topography, and types wheels on machines used. Thus, this study aimed evaluate WBV in bulldozers hydraulic excavators for forest plantation order identify possible ergonomic problems propose improvements workin...
