Matching principle

Mr. Ray Kurzweil, renowned inventor and author of The Singularity is Near, wrote in 2001 that technological progress was increasing twofold every decade, “We won’t experience 100 years of progress in the 21st century-it will be more like 20,000 years of progress (at today’s rate)” (qtd. in Berman and Dorrier). We are only in the beginning of the 21st century and yet technology is advancing faster than our ability to adapt! Technology has given society convenience and a higher standard of living

2.6.2 Radiation Pattern Microstrip Patch Antenna has radiation patterns that can be simply calculated. The source of the radiation of the electric field at the gap of the edge of the Microstrip element and the ground plane is main factor to the accurate calculation of the pattern for the patch antenna. Simply it can be said that the power radiated or received by the antenna is the function of angular position and radial distribution from the antenna [24]. In the fig.24 [9] below we can see the side

Background The CCA police department began analyzing evidence that was collected in an abandoned building at the Lowry campus on 6th Ave and Alton way. The building was abandon and boarded up five years ago, but it showed signs of forced entry. During the Investigation of the scene, CCA police officers found a human skeleton. The skeletal remains were found dressed in what appeared to be a bloody t-shirt and jeans. No identification was found yet but one of the officers brought a theory to this

4. Design Challenges: The desired operating frequency are given by: 1. US FCC regulation as 3.1 to 10.6GHz 2. European regulation as 6.0 to 8.5GHz A general definition of UWB is stated with the relative bandwidth (fH-fL)/(fH+fL) >0.2 Where fh and fL are upper and lower band limits, respectively. Relative bandwidth in excess of 100% are possible for some antenna types. A. Antenna Characterization Parameters: In contrast to classic narrow-band antenna theory, where the antenna characteristics are regarded

Inspection Using a Hierarchical Pattern Matching Algorithm T. .Mukthar Ahamed Academic Consultant Dept. of CSE YSR Engineering College of YVU Proddatur, India tmukthar@gmail.com Abstract: Detection engines capable of inspecting packet payloads for application-layer network information are urgently required. The most important technology for fast payload inspection is an efficient multipattern matching algorithm, which performs exact string matching between packets and a large set of predefined

prospects. However, revenue recognition requirements in U.S. GAAP differ from those in IFRS, and both sets of requirements are considered to be in need of improvements. Accordingly, the FASB and the IASB initiated a joint project to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and IFRS that would 1) remove inconsistencies and weaknesses in existing revenue recognition standards and practices; 2) provide a more robust framework for addressing

We conducted a literature review as a part of our study, of recent research in the area of sinuous antennas. From the review, it is clear that sinuous antennas are very useful due to their wideband ability and dual polarized application. Hence, we can find a number of applications where these antennas are being used. Waldschmidt et al.1 have conducted a study and evaluated the use of the sinuous antenna for wideband multiple-input multiple-output (MIMO) and diversity applications. They found that

DGS is more advantageous than PBG or EBG structures: (1) For implementing EBG structures, a very large area is required to implement the periodic pattern and it is also very difficult to define the unit element of EBG structure whereas DGS structures has properties similar to EBG and the geometry of DGS can be one or very few etched structures which is very simpler and also does not require large area for implementation of it. (2) DGS can be easily designed and implemented. It has higher precision

A microstrip antenna consists of conducting patch and a ground plane separated by dielectric substrate. The early work of Munson on microstrip antennas for use as a low profile flush mounted antennas on rockets and missiles showed that this was a practical concept for use in many antenna system problems. Different mathematical models were developed for this antenna and its applications were extended to many other fields. The number of articles published in the journal papers for the last ten years

algorithm has a almost 100% correct classified rate for Human and Wrench. We noticed that the Airplanes class is of the lowest correct rate except for the top 3 ranks. And the hit rate declined rapidly which make it singled out from the Table I. The matching distance in this class is carefully investigated and the distance revealed that our descriptors
