In the grinding process of workpiece, because wheel will produce wear, it is difficult to control machining accuracy workpiece by grinder itself. Using radial measuring instrument measure size in real time, detect change and guide adjustment parameters can improve production efficiency reduce cost. It an important link grinder. Different from traditional two-point contact on-line measurement te...

Abstract In this study, a light weight portable manual food grinder for domestic use was designed and fabricated to meet grinding needs that arise from erratic power supply in Nigeria. The design analysis crank lever parameters conveyor shaft diameter were done. To make the weight, body of machine, front cover house mechanisms support stand printed with Fused deposition modelling 3D printer. le...

Abstract Technical failures in machines are major sources of unplanned downtime any production and result reduced efficiency system reliability. Despite the well-established potential Machine Learning techniques condition-based maintenance (CBM), lack access to failure data has limited development a holistic approach address machine-level CBM. This paper presents practical for mode prediction u...

Nonmissile low-velocity penetrating brain injuries are unusual among civilian population. Work-related penetrating head wounds are rarer among this group. Here, we report two rare cases of penetrating head wounds caused by industrial grinder tool. The patients (both men) were struck to the head by detached blades of the grinder tool. Depressed fractures, penetrated bone fragments, and dural lac...

In this paper, we present a study of a large corpus of student logic exercises in which we explore the relationship between two distinct measures of difficulty: the proportion of students whose initial attempt at a given natural language to first-order logic translation is incorrect, and the average number of attempts that are required in order to resolve the error once it has been made. We dem...

Experiments were conducted on soft-tissue and bone preparations to determine the morphological characteristics of angle grinder injuries. The grinding effect of the rotating cutting-off wheel causes severances with local loss of tissue, resulting in tool-specific wound features. Superficial skin notches and (incomplete) severances of bony structures are of particular significance. Mutual trace ...
