A Smart Hybrid System for Parking Space Reservation in VANET

Nowadays, developed and developing countries using smart systems to solve their transportation problems. Parking guidance intelligent systems for finding an available parking space, are considered one of the architectural requirements in transportation. In this paper, we present a parking space reservation method based on adaptive neuro-fuzzy system(ANFIS) and multi-objective genetic algorithm....

Bi-space pullback attractors for closed processes

In the description of the long-time behavior of solutions to nonautonomous differential equations the notion of a pullback attractor plays a similar role as the global attractor in autonomous dynamical systems. We present the theorem on the existence of a pullback attractor if the evolution process is a family of closed operators. The abstract result is formulated in the context of the smoothin...

Closed reservoir system for angiography.

For many years , radiologists kept saline and contrast material in open basins for use during angiographic procedures . More recently , c losed systems have been advocated to avoid contamination by foreign bodies such as cotton fibers or talc [1, 2]. Such arrangements use intravenous sets hung on a trolley , which is often positioned behind the radiologist and requires that an assistant turn hi...

Closed Curves and Space Curves

So far we have discussed only ‘local’ properties of (plane) curves. These properties depend only on the behavior of a curve near a given point, and not on the ‘global’ shape of the curve. Now let us look at some global results about curves. The most famous, and perhaps the oldest, of these is the ‘isoperimetric inequality’, which relates the length of a certain ‘closed’ curve to the area it con...

Closed Strings in Misner Space

Misner space, also known as the Lorentzian orbifold R1,1/boost, is one of the simplest examples of a cosmological singularity in string theory. In this work, the study of weakly coupled closed strings on this space is pursued in several directions: (i) physical states in the twisted sectors are found to come in two kinds: short strings, which wind along the compact space-like direction in the c...
