Abstract: India had reported 150,785 road fatalities in year 2016 and its Karnataka state appeared at 4th rank with 11,133 road fatalities in 44403 road crashes. Age group below 35 years is at most risk with 59 percent share in fatalities in Karnataka. Road engineering is a major road safety issue as Karnataka National & State Highways reported 65 percent of the state road fatalities. Road junctions are critical locations from safety point of view which claimed 3313 lives, 30 percent of fatalities. Drivers killed in road crashes in Karnataka were 32 percent of fatalities (3587 drivers). It is a matter of grave concerns that 32 percent drivers-killed were young drivers below 25 years age. At this age decision making capacity in critical conditions is biologically in developing stage. The facts identify need of strengthening the system of drivers’ training. Drivers’ fault was reported in 88 percent fatal road crashes in Karnataka. Investigations solely blame drivers in most road crashes and si

Abstract: Positioning tables supported by linear bearings are adopted for various machines such as material handling robots and machine tools. The accuracy of positioning tables is acknowledged to be essential for the machines employing the positioning tables. For instance, deflection of a positioning table for a machine tool during operation affects the machining accuracy for the machine tool. Thus, it is of great importance to accurately predict the deflections of the positioning tables in the design process. However, the deflections of positioning tables supported by multiple linear roller bearings (LRBs) are not easy to estimate because of the complicated characteristics of LRBs with regard to the system configuration and applied load. In this study, the static deflection of a large positioning table containing a number of LRBs was investigated. To this end, an improved simulation model for the deflection of a LRB subjected to vertical load was employed. The static deflection model of a LRB
