EMIP: The eye movements in programming dataset

A large dataset that contains the eye movements of N=216 programmers of different experience levels captured during two code comprehension tasks is presented. Data are grouped in terms of programming expertise (from none to high) and other demographic descriptors. Data were collected through an international collaborative effort that involved eleven research teams across eight countries on four continents. The same eye tracking apparatus and software was used for the data collection. The Eye Movements in Programming (EMIP) dataset is freely available for download. The varied metadata in the EMIP dataset provides fertile ground for the analysis of gaze behavior and may be used to make novel insights about code comprehension

Modernization of the Turning Mechanism of the T -72 Turret

Abstract In the process of T-72 tank modernization, reconstruction of the spherical pathway of the turret turning mechanism was carried out. Following the the turret load analysis at the moment of firing and identification of the allowance in the bearing, the turret turning mechanism was rebuilt completely. Analyses show that the cannon muzzle oscillation is caused by several factors. Having analyzed them, specific measures were adopted, such as for instance the elimination of allowance in the spherical pathway seating of the tank turret
