Novel Method for Modeling IBIS4.2 Four-Level Hysteresis Behavior in an Analog Simulator
Sabry, Yasser M.; Hareedy, Ahmed; Selim, Mohamed A. (2008-01-01)
IBIS4.2 (I/O Buffer Information Specification) standard describes the hysteresis behavior from one simulation point to the other. In an analog simulator, solution is obtained based oil multiple iterations in between simulation points. These iterations call lead to undesired behavior. The common problem that might be encountered with this specific behavior in an analog simulator due to iterations will be discussed, and a novel way for implementation that overcomes this problem will be proposed.
Novel multi-band metamaterials in microwave region with applications in antennas
Küçüksarı, Öznur; Sayan, Gönül; Department of Electrical and Electronics Engineering (2014)
This dissertation is focused on the design, fabrication, and characterization of multi-band metamaterials in microwave region with novel applications in antennas with the following outcomes: In the first part of dissertation, important concepts that have to be considered during the design, simulation and characterization of planar metamaterial arrays are investigated. All investigations are performed using the planar dual band nested U-ring resonator (2-NURR) metamaterial array that is a novel exemplar of t...
Novel position measurement and estimation methods for CNC machine systems
Kılıç, Ergin; Dölen, Melik; Department of Mechanical Engineering (2007)
Precision control of translational motion is vital for many CNC machine tools as the motion of the machinery affects the dimensional tolerance of the manufactured goods. However, the direct measurement along with the accurate motion control of machine usually requires relatively expensive sensors i.e. potentiometers, linear scales, laser interferometers. Hence, this study attempts to develop reference models utilizing low-cost sensors (i.e. rotary encoders) for accurate position estimation. First, an indire...
Prototype Implementation of DynaVote e-Voting Protocol
Cetinkaya, Orhan; Koc, Mehmet Levent (2009-06-30)
Voting is regarded as one of the most effective methods for individuals to express their opinions on a given topic. Electronic voting (eVoting) refers to the use of computers or computerised voting equipments to cast ballots in an election. eVoting performed over Internet can be universally accepted in the upcoming years due to the fact that Internet plays key roles in people's lives. The DynaVote eVoting protocol claims that it is practical over a network since it does not use complex algorithms and has no...
Improved ADMM-Based Algorithm for Multi-Group Multicast Beamforming in Large-Scale Antenna Systems
Demir, Özlem Tuğfe; Tuncer, Temel Engin (2018-08-07)
In this paper, we consider beamformer design for multi-group multicasting where a common message is transmitted to the users in each group. We propose a novel effective alternating direction method of multipliers (ADMM) formulation in order to reduce the computational complexity of the existing state-of-the-art algorithm for multi-group multicast beamforming with per-antenna power constraints. The proposed approach is advantageous for the scenarios where the dimension of the channel matrix is less than the ...
