The problem of scalability of trajectories in homogeneous and locally homogeneous systems is considered. It is shown that the homogeneous systems have scalability property, and locally homogeneous systems possess this property approximately. The issue of closeness of trajectories for the system and its local homogeneous approximation is investigated. The notions of scale invariance and fold change detection are also studied. The results are illustrated by a cascade system analysis.

We consider a class of convex feasibility problems where the constraints that describe the feasible set are loosely coupled. These problems arise in robust stability analysis of large, weakly interconnected uncertain systems. To facilitate distributed implementation of robust stability analysis of such systems, we describe two algorithms based on decomposition and simultaneous projections. The first algorithm is a nonlinear variant of Cimmino's mean projection algorithm, but by taking the structure of the constraints into account, we can obtain a faster rate of convergence. The second algorithm is devised by applying the alternating direction method of multipliers to a convex minimization reformulation of the convex feasibility problem. Numerical results are then used to show that both algorithms require far less iterations than the accelerated nonlinear Cimmino algorithm.

The paper is concerned with the control of doubly fed induction generator applied in wind power technology. Assuming stator flux oriented vector control, the torque and power relations are derived. Using the relations, the slip versus torque and slip versus stator reactive power characteristics are drafted in subsynchronous and in supersynchronous state for investigating the control possibilities of the generator side converter supplying the rotor circuit. The effects of the d and q component of the converter output voltage for the torque, power and speed are studies in qualitative and quantitative way. The active and reactive power flows in stator and rotor side are shown.

As no civil infrastructure can escape aging and deterioration,health monitoring can prevent and report serious structural damage. With the rapid evolution of computer vision algorithms,optical-based systems become an increasingly feasible option for automatic monitoring. This paper proposes a cheap and flexible standalone system based on marker tracking to report deflection of structural elements of civil infrastructure. A single marker is placed on tracked objects,which allows unambiguous identification of objects and accurate movement tracking. Accuracy of the system is discussed by presenting a theoretical analysis of the translation error. Additionally,as a proof of concept we extend our work with a low-cost laboratory test implementation.
