Several non-minimum-bandwidth partial-response-signaling (PRS) techniques were compared in the above paper (ibid., vol.COM-35, p.475-80, April 1987). One of the criteria used for the comparison was the robustness to the timing jitter. The commenter shows that according to this criterion the duobinary signaling technique is superior to the dicode scheme at low values of the roll-off factor, in contradiction to the conclusion in the original study. In reply the author agrees that the comment is correct and that unnormalized and normalized figure-of-merit plots show different aspects of timing jitter sensitivity as a function of excess bandwidth.


Performance comparison of the 3D-printed and injection-molded PLA and its elastomer blend and fiber composites
Kaynak, Cevdet (2019-04-01)
The purpose of this study was to compare the performance of polylactide (PLA)-based materials shaped by the traditional injection molding technique versus three-dimensional (3D)-printing additive manufacturing. Comparisons were performed not only for neat PLA but also for its thermoplastic polyurethane elastomer (TPU) blend and for its E-glass fiber (GF)-reinforced composites. Performance comparison of the injection-molded and 3D-printed specimens was especially conducted to compare their mechanical propert...
Thermal and structural characterization of polypyrrole by direct-insertion probe pyrolysis mass spectrometry
Uyar, T.; Toppare, Levent Kamil; Hacaloğlu, Jale (2001-03-15)
There have been extensive studies on structural characterization of conducting polypyrrole, PPY using various techniques. The two proposed structures are the aromatic form corresponding to the undoped state and the quinoid form corresponding to the doped state. However, actual structure appears to be more complicated and the relationship between the dopant used and the structure was not totally clarified. In this study direct insertion probe pyrolysis mass spectrometry technique was applied to monitor therm...
Chatter Reduction in Turning by Using Piezoelectric Shunt Circuit
Yiğit, Ufuk; Ciğeroğlu, Ender; Budak, Erhan (null; 2014-02-11)
In this paper, the effect of piezoelectric shunt damping (PSD) on chatter vibrations in turning process is studied. Chatter is a self-excited type of vibration that develops during machining due to process-structure dynamic interactions resulting in modulated chip thickness. Chatter is an important problem, since it results in poor surface quality, reduced productivity and reduced tool life. The regenerative chatter results from phase differences between two subsequent passes of the cutting tool and occurs ...
Filter design software by synthesis method
Yayla, İhsan; Yıldırım, Nevzat; Department of Electrical and Electronics Engineering (2009)
In this study, Window-based computer program, named Synthesis Software, is developed for designing filters with equal-ripple or maximally flat passbands and general stopbands by using cascade synthesis technique in transformed frequency domain. Synthesis technique is applicable to lumped element and commensurate line distributed element filters with Lowpass, Highpass or Bandpass characteristics. Singly or Doubly terminated filters can be synthesized. friendly environment for typing in the parameters of the ...
Nonlinear Vibrations of a Beam with a Breathing Edge Crack Using Multiple Trial Functions
Batihan, Ali C.; Ciğeroğlu, Ender (2016-01-28)
In this paper, a beam like structure with a single edge crack is modeled and analyzed in order to study the nonlinear effects of breathing crack on transverse vibrations of a beam. In literature, edge cracks are generally modeled as open cracks, in which the beam is separated into two pieces at the crack location and these pieces are connected to each other with a rotational spring to represent the effect of crack. The open edge crack model is a widely used assumption; however, it does not consider the nonl...
