Circuit models with mixed lumped and distributed elements for passive one-port devices
(Işık Üniversitesi, 2006-01-23)In this thesis, to model measured data obtained from an actual passive one-port device, a circuit modeling method with mixed lumped and distributed elements is proposed. Namely, measured data is modelled by means of its ... -
Co-training using prosodic, lexical and morphological information for automatic sentence segmentation of Turkish spoken language
(Işık Üniversitesi, 2018-01-15)Sentence segmentation of speech aims detecting sentence boundaries in a stream of words output by the speech recognizer. Sentence segmentation is a preliminary step toward speech understanding. It is of particular importance ... -
Cooperative strategies, achievable rates and resource allocation for OFDMA channels
(Işık Üniversitesi, 2011-07-28)The design of next generation wireless communication systems brings along new challenges, since the degrading factors such as fading and multi-user interference become harder to deal with as the number of users and the ... -
Design and optimization of multiuser cooperative protocols for wireless networks
(Işık Üniversitesi, 2014-09-12)Recently, the main trend in wireless communications has shifted from voice transmission to data communication. Naturally, this shift caused an increase in the data rate and bandwidth requirements. Being a limited and thus ... -
Facial expression recognition based on facial anatomy
(Işık Üniversitesi, 2013-06-06)In this thesis we propose to determine the underlying muscle forces that compose a facial expression under the constraint of facial anatomy. Muscular activities are novel features that are highly representative of facial ... -
Head-on collisions of solitary waves
(Işık Üniversitesi, 2015-12-11)The interaction of solitary waves in various physical media is a long time studied subject in nonlinear wave theory. For overtaking collision between solitary waves, one can use the inverse scattering transform method to ... -
An inverse source problem connected thermoacoustic imaging in multi-layer planar medium
(Işık Üniversitesi, 2018-06-04)In this thesis, we mentioned imaging technics used today, and microwave induced thermoacoustic procedure and imaging. We made literature survey about solution of the thermoacoustic equation for homogeneous and inhomogeneous ... -
KeNet: a comprehensive Turkish wordNet and its applications in text clustering
(Işık Üniversitesi, 2018-06-07)In this thesis, we summarize the methodology and the results of our e?orts to construct a comprehensive WordNet for Turkish. Most languages have access to comprehensive language resources. Traditional resources like bilingual ... -
Metamutator: Its Realizations and Its Applications
(Işık Üniversitesi, 2019-07-22)Mutators became very popular after 1971, when Leon Chua realized the memristor, his postulated fourth circuit element, using them. The reason for the popularity of mutators, which are easily realizable 2-port devices, lies ... -
Multiband and concurrent matching network design
(Işık Üniversitesi, 2020-02-05)Multiband network design has become a big issue due to the current improvements in RF and MW technologies. Since the new wireless protocols come up fast such as 3G, 4G, 5G etc., the RF and MW hardware must be designed to ... -
New approaches for channel estimation in wireless communications
(Işık Üniversitesi, 2006-03-10)This thesis first proposes a conputationally efficient, pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorthm for the orthogonal frequency division multiplexing OFDM systems in unkonown ... -
Parallel proposition bank construction for Turkish
(Işık Üniversitesi, 2019-04-02)PropBank is the bank of propositions which contains hand-annotated corpus for predicate-argument information and semantic roles or arguments. It aims to provide an extensive dataset for enhancing NLP applications such as ... -
Ring array processing for forward-looking intravascular and intracardiac ultrasonic imaging
(Işık Üniversitesi, 2010-06-08)Forward-looking (FL) catheter-based imaging systems are highly desirable for guiding interventions in IVUS and ICE applications. One of the main challenges in the array based FLIVUS systems is the large channel count which ... -
Software defect prediction using Bayesian networks and kernel methods
(Işık Üniversitesi, 2012-07-01)There are lots of different software metrics discovered and used for defect prediction in the literature. Instead of dealing with so many metrics, it would be practical and easy if we could determine the set of metrics ... -
Solid-state arrays and beamformers for side-looking intravascular ultrasonic imaging
(Işık Üniversitesi, 2010-06-08)Current solid-state intravascular ultrasound (IVUS) devices use a one-dimensional (1-D) rectangular array wrapped around the cylindrical catheter. Beamforming in these devices is limited to synthetic phased array processing, ...
