This paper considers the problem of visual-inertial sensor fusion in the cooperative case and it provides new theoretical contributions, which regard its observability and its resolvability in closed form. The case of two agents is investigated. Each agent is equipped with inertial sensors (accelerometer and gyroscope) and with a monocular camera. By using the monocular camera, each agent can o...

The counterpart for Euler’s buckling problem is Greenhill’s problem, which studies the forming of a loop in an elastic beam under torsion. In context twisted shafts, optimal shape along its axis searched. A priori form cross-section remains unknown. For solution actual stability equations take into account all possible convex and simply connected shapes cross-section. cross-sections are similar...

Conventionally, space resection has been solved by iterative means, although for many years photogrammetrists have attempted to find a solution in a closed form. Recent work with the projective transformation approach as utilized in the Direct Linear Transformation (DLT) formulation has led to a closed solution for a plane object. Tests of this solution are reported together with a critical rev...

Using an idealized semianalytical model of charge transport for InAs-based tunneling FET, it is shown that the output and transfer characteristics can be accurately reproduced and could be used to develop compact models. The use of a mathematical approximation for the analytical solution of the surface potential is vital here to minimize the computation time. The 20-nm gate homojunction and 40-...
