Current free-to-play mobile games use various mechanics to control player progression. Through the game Jelly Splash, we study three such gating mechanics: occasional spikes in level difficulty, chapter gates every 20 levels, and a limited number of lives regenerating slowly over time. Using telemetry data from a quarter-million players, we explore how players approach each gating mechanic, foc...

The nonlinear thermo-mechanic coupling effect refers to the interaction between dynamic characteristics of a dual-rotor system and thermal an intershaft bearing. In this paper, is proposed studied by operating radial clearance load A model under bearing established considering factors such as Hertzian contact force obtained based on responses system. Based this, proposed. attained according tem...

The real contact area of rough surfaces has significant importance in many engineering applications, such as tribology, wear, lubrication and seals. A continuous observation length-dependent mechanic model without adhesion is proposed, which assumes that the surface divided into ideal subplanes. However, ignores elastoplastic deformation asperities, standard deviation subplanes’ heights assumed...

background: the aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age. materials and methods : twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angels were estimated by this algor...

at the present study, different properties of sarin with the formula [(ch3)2cho]ch3pof was studiedin gas phase. geometrical optimizations of sarin, single point calculation, nmr and electricalparameters were carried out in gas phase with the hartee -fock method coupled to 6-31g* basis setsfor all atoms. the results obtained from a comparison between tables and charts came up fordiscussion and a...
