This paper aims to present the design of a new 3D-printed continuously variable transmission (CVT) developed for an electric vehicle prototype competing in Shell Eco-marathon battery category, world-wide energy efficiency competition sponsored by Shell. The proposed system is composed polymeric conic geared friction wheel assembled motor axle and directly coupled rear tire vehicle. conical shap...

Silicon nanoclusters exhibit light emission with direct-like ns–µs time dynamics; however, they show variable synthesis and structure, optical, electronic characteristics. The widely adopted model is a core–shell in which the core an indirect tetrahedral absorbing Si phase, while shell network of re-structured H–Si–Si–H molecular emitting phases, two connected via back Si–Si bonds, exhibiting p...

Conical stromatolites are thought to be robust indicators of the presence of photosynthetic and phototactic microbes in aquatic environments as early as 3.5 billion years ago. However, phototaxis alone cannot explain the ubiquity of disrupted, curled, and contorted laminae in the crests of many Mesoproterozoic, Paleoproterozoic, and some Archean conical stromatolites. Here, we demonstrate that ...

We present a method for the generation of high kinetic energy attosecond electron packets via magnetostatic and aperture filtering of conical surface plasmon (SP) accelerated electrons. The conical SP waves are excited by coupling an ultrafast radially polarized laser beam to a conical silica lens coated with an Ag film. Electromagnetic and particle tracking models are employed to characterize ...

The output of a piezoelectric nanogenerator based on ZnO nanowire is largely affected by the shape of nanowire. In order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance. This paper presents the various behavior of ...

We study the relation between stellar dynamo-wave propagation and structure of magnetic field. Modeling dynamo waves by well-known Parker migratory dynamo, we vary intensity drivers in order to obtain activity-wave toward Equator (as solar-activity cycle) or towards Poles. match field dynamo-active shell with that surrounding material, using a simple dissipative magneto-hydrodynamic system for ...

We show that the set of conical points of a rational function of the Riemann sphere supports at most one conformal measure. We then study the problem of existence of such measures and their ergodic properties by constructing Markov partitions on increasing subsets of sets of conical points and by applying ideas of the thermodynamic formalism. 1 Introduction. In this paper we recall from U2] the...
