VOICE OVER IP NETWORKS: QUALITY OF SERVICE, PRICING AND SECURITY
(2008)
The growth of the Internet over the past decade together with the promise of lower costs to the customer has led to the rapid emergence of Voice over Internet Protocol (VoIP). As a real-time application in large scale ...
Electromagnetic Modeling Methods for Microstrip Patch Antennas up to the Millimeter-Wave and Sub-Terahertz Bands
(2022-12-16)
In the current world of highly integrated communications, reliable and robust systems will be required to develop the 6G networks. The millimeter-wave band (30 GHz–100 GHz) and the sub-terahertz band (100 GHz–300 GHz) have ...
Computational Electromagnetics Applied to Scattering Observed by Polarimetric Weather Radar
(2015-12-18)
The primary topics of this dissertation are issues existing in the current ensemble scattering procedures. These procedures are failing to quantitatively reproduce polarimetric signatures from resolution volumes filled ...
PHYSICAL TOPOLOGY DESIGN AND ROUTING ALGORITHMS FOR DEGREE-CONSTRAINED FSO MESH NETWORKS
(2008)
Free-space optical (FSO) mesh networks are emerging as broadband communication networks because of their high bandwidth (up to Gbps), low cost, and easy installation. However, there are two existing problems in the deployment ...
Theoretical and experimental investigation of IV-VI mid-infrared multiple quantum wells vertical cavity surface emitting lasers.
(2003)
Lateral mode suppression techniques other than reduction of pump spot size need to be developed. Air-post pillar structure and electrically pumped configuration certainly need to be investigated.
A study of the optical transmission properties of the polymer HPG.
(2000)
Hydroxypropyl Guar (HPG) is a polymer used extensively in the petroleum industry for fracturing oil and gas wells. Understanding the transmission of electromagnetic (EM) radiation in these fluids plays an essential role ...
The multi-layered schema of an extended entity-relationship model /
(1984)
In a database design process, the database model used is essential for producing a good conceptual schema. In some database models, like IMS and CODASYL, a conceptual schema contains too many implementation details which ...
A new multilateration optimization technique for air traffic management and surveillance.
(2007)
Abstract not available.
Multi-area unit commitment via sequential method and a DC power flow network model.
(1997)
The sequential bidding unit commitment method employs an iterative procedure. Each iteration consists of two phases--the sequential commitment phase and the price adjustment phase. The principle of the sequential bidding ...
Channel coding and reduced-complexity detection for magnetic recording.
(1997)
As an application, a modified EEPR4 (MEEPR4) channel with a 3-candidate LVA is shown to exhibit a 2 dB LVA gain. In addition, an error detection code is designed to increase the minimum distance by more than 2 dB with a ...
