Diode lasers have a broad wavelength range, from the visible to beyond 2.2μm. This allows for various applications in the defense sector, ranging from classic pumping of DPSSL in range finders or target designators, up to pumping directed energy weapons in the 50+ kW range. Also direct diode applications for illumination above 1.55μm, or direct IR countermeasures are of interest. Here an overvi...

Abstract With the rapid development of national power industry, security information network has been widely concerned by society, and related impact also prominent. At this stage, technology is more inseparable from network, so become important, if a serious threat in practical application, loss caused will be unbearable. In process controlling one most important effective methods active defen...

This paper studies the dimension of secant varieties to Segre varieties. The problem is cast both in the setting of tensor algebra and in the setting of algebraic geometry. An inductive procedure is built around the ideas of successive specializations of points and projections. This reduces the calculation of the dimension of the secant variety in a high dimensional case to a sequence of calcul...

Let X ⊂ P be an n-dimensional connected projective submanifold of projective space. Let p : P → P denote the projection from a linear P ⊂ P . Assuming that X 6⊂ P we have the induced rational mapping ψ := pX : X → P. This article started as an attempt to understand the structure of this mapping when ψ has a lower dimensional image. In this case of necessity we have Y := X ∩ P is nonempty. The s...

State estimation is an important power system tool used to best estimate the system state through analysis of remotely collected sensor measurements and the power system topology. The reliability of the estimated output depends on the quality of the input measurements. Therefore, grid operators use Bad Data Detection (BDD) techniques to filter out grossly erroneous measurements from the state e...

The power supply system of future communities can be considered in the form of a small microgrid or a nanogrid which is mainly based on renewable energy resources. Such a system can lead to a sustainable development of electrical systems and can help the current and future generations to access the benefits of electricity without adding more emissions and pollutions to the environment. A nanogr...
