New Pulse Shapes for CPM Signals
Doyuran, Enis; Tanık, Yalçın (2006-05-10)
A study on finding new pulse shapes for binary CPM (Continuous Phase Modulation) signals to achieve better spectral and detection performance is carried out. Under the constraint that the power spectral density stays below the GSM spectral envelope, pulse shape is optimized to minimize the error probability. Polynomials are utilized in representing pulse shapes. The performance depends on the degree of the polynomials and the pulse length (L). With 8(th) degree polynomials having 4 free parameters, optimiza...
New design methods for polyhedral linkages
Kiper, Gökhan; Söylemez, Eres; Department of Mechanical Engineering (2006)
This thesis analyses the existing types of polyhedral linkages and presents new linkage types for resizing polyhedral shapes. First, the transformation characteristics, most specifically, magnification performances of existing polyhedral linkages are given. Then, methods for synthesizing single degree-of-freedom planar polygonal linkages are described. The polygonal linkages synthesized are used as faces of polyhedral linkages. Next, the derivation of some of the existing linkages using the method given is ...

New morphological methods to generate two-dimensional curve offsets
Dölen, Melik; Yaman, Ulaş (2014-04-01)
For the purpose of generating 2D curve offsets used in 2.5D machining, four new methods based on morphological operations on different mathematical entities are presented in this paper. All of the methods, which lend themselves for parallel processing, exploit the idea that the boundaries formed by a circular structuring element whose center sweeps across the points on a generator/base curve comprise the entire offsets of the progenitor. The first approach, which is a carry-over from image processing, makes...
New methods for public key cryptosystems based on XTR
AKLEYLEK, SEDAT; KIRLAR, Barış Bülent (2015-12-01)
In this paper, we propose novel deterministic and probabilistic public key cryptographic schemes based on an effective and compact subgroup trace representation cryptosystem to handle with the problem of secure and efficient communication between the server and resource-constrained device. The proposed schemes use the hardness of the Trace-discrete logarithmic like problem. We also show that the deterministic version of the proposed scheme is a one-way trapdoor, and the probabilistic version of the proposed...
