If only the need to provide energy to a city is considered, the find more info relevant figure is simply the total amount of energy that must be supplied. The traditional solution to this problem is to concentrate all readings in a central processor. The calculation is indeed very simple (most likely a simple sum), but the difficulty is in obtaining all of this information at the central server and possibly also in the size of the server, provided that it is capable of processing such a large volume of information. We might consider a second alternative, where instead of using a single central server, multiple servers are placed on a smaller scale with a distributed approach, which could offer some advantages over the centralised solution.

Due to the remarkable growth in the video surveillance market over the last few years [1�C3], high-quality imaging results from Inhibitors,Modulators,Libraries zoom operation are now demanded by consumers [4,5], particularly in traffic management and security monitoring [6�C8]. Maintaining image sharpness or focus during the entire zoom process is the main challenge of zoom tracking. Figure 1 shows the zoom tracking effect as the zoom is changed from a wide-angle zoom to a tele-angle zoom. As shown in this figure, the plant remains in-focus as the zoom is changed by the user in the presence of zoom tracking. However, the image becomes out-of-focus in the absence of zoom tracking, and the image finally clarifies after zoom tracking due to an auto-focusing (AF) [9] algorithm.Figure 1.Illustration of the zoom tracking effect.1.1.
Zoom Tracking PrincipleUsers often utilise two different zoom options in a digital video system: optical zoom and digital zoom. Digital zoom works by cropping and subsequently enlarging a captured image, which produces an image of lower optical resolution. In contrast, optical zoom uses the optic lens to bring the subject closer [10]. In this paper the zoom tracking problem Inhibitors,Modulators,Libraries is only studied for optical zoom. Figure 2(a) shows an actual zoom system, and its structure chart is shown in Figure 2(b).Figure 2.(a) Illustration Inhibitors,Modulators,Libraries of an actual zoom system; (b) The structure of a zoom system; (c) Zoom tracking mechanism.Figure 2(c) introduces the zoom tracking mechanism in detail. When the zoom is changed from wide-angle to tele-angle, the zoom lens focal length increases from Fwide to Ftele, whereas the angle of view reduces from ��wide to ��tele.
In response to this change, the in-focus plane (image distance) Inhibitors,Modulators,Libraries Entinostat should shift during this process. For an object at a distance d, sd(zwide) and sd(ztele) are defined as the image distance at wide-angle and tele-angle zooms, respectively. Thus, when the zoom is changed from wide-angle to tele-angle, to maintain image sharpness, the image sensor must be moved from the wide-angle in-focus plane at sd(zwide) to the tele-angle in-focus plane at sd(ztele).
