Efficiency Enhancement of Bowtie Photomixer Antenna by Using Resistively Loaded Line

YILMAZ, Adem | ÜNLÜ, Mehmet

In this paper, the effects of the DC bias lines on bowtie terahertz photomixer antenna are investigated, and a method, namely resistively loaded lines (RLL), is proposed to compensate the effects of the DC bias lines. The numerical results of the bowtie antenna show that RLL almost removes the effects of the bias lines compared to that of the commonly used bias line types, such as coplanar stripline and photonic bandgap type bias lines.

Profiling Subscribers According to Their Internet Usage Characteristics and Behaviors

ÖZTOPRAK, Kasım

Providers (SP) are wishing to increase their Return of Investment (ROI) by utilizing the data assets generated by tracking subscriber behaviors. This results in the ability of applying personalized policies, monitoring and controlling the service traffic to subscribers and gaining more revenues through the usage of subscriber data with ad networks. In this paper, a framework is developed to monitor and analyze the Internet access of the subscribers of a regional SP in order to categorize the subscribers into an interest category from The Interactive Advertising Bureau (IAB) categories. The stu ...Daha fazlası

A Multistage Deep Learning Algorithm for Detecting Arrhythmia

ALLAHVERDİ, Novruz | KUTLU, Yakup | ALTAN, Gökhan

Deep Belief Networks (DBN) is a deep learning algorithm that has both greedy layer-wise unsupervised and supervised training. Arrhythmia is a cardiac irregularity caused by a problem of the heart. In this study, a multi-stage DBN classification is proposed for achieving the efficiency of the DBN on arrhythmia disorders. Heartbeats from the MITBIH Arrhythmia database are classified into five groups which are recommended by AAMI. The Wavelet packet decomposition, higher order statistics, morphology and Discrete Fourier transform techniques were utilized to extract features. The classification pe ...Daha fazlası

Sliding Mode Control of a Two-link Robot Manipulator Using Adams & Matlab Software

İLGEN, Sinan | DURDU, Akif | GÜLBAHÇE, Erdi | ÇAKAN, Abdullah

This paper presents the design of a sliding mode controller (SMC) for trajectory tracking problem for a two-link planar robot manipulator. A virtual prototype of the manipulator has been built by using Adams software. Also, the controller works is achieved in Matlab/Simulink software. The system is simulated in both Matlab and Adams software together which is called co-simulation. The manipulator system has two inputs (torques of actuators) and four outputs (angle of 1st joint, angle of 2nd joint and x-y components of end effector position). The sliding mode controller (SMC) is designed with t ...Daha fazlası

mCSDN: A Software Defined Network Based Content Delivery System with D2D Contribution

ÖZTOPRAK, Kasım

Mobile Content Delivery systems are becoming more popular with the increasing capacity demand by mobile subscribers. In order to reduce the total outgoing traffic a Content Delivery System for Mobile Operators (mCSDN) was proposed. The strength of the proposed system inspired by the idea of using Device-to-Device Communication (D2D), and Software Defined Networks (SDN) based middleware as the orchestrator of mobile device management and content locating. The approach of the study is assumed to be ``using the content from the node as close as possible to the mobile user{''}. The video used in t ...Daha fazlası

Statistical Analysis of Electromagnetic Structures and Antennas Using the Polynomial Chaos Expansion Method

AÇIKGÖZ, Hulusi | MITTRA, Raj

Electromagnetic (EM) structures such as antennas, resonators, are widely used in EM communication systems. It is not uncommon to find that the performance characteristics of these structures are not as expected because of the uncertainties introduced during the manufacturing process. These uncertainties may arise, for instance, from variations of the dimensions of the device or its material properties, e.g., permittivity and permeability. A statistical tool based on the use of the Polynomial Chaos Expansion (PCE) technique is proposed in this work. The results of investigation of two EM struct ...Daha fazlası

Statistical Investigation of a Dual-Band Wearable Patch Antenna

AÇIKGÖZ, Hulusi | MITTRA, Raj

We present a stochastic modeling strategy for studying a wearable textile antenna under different manufacturing conditions. The studied device is a patch antenna designed for energy harvesting, which operates at the GSM and DCS bands, 900MHz and 1800MHz, respectively. The performance of the conductive patch printed on a textile substrate backed by a ground plane is investigated. A stochastic approach is employed to assess the variability of the observable because of the uncertainties introduced in the manufacturing process, such as laminating and embroidering.

İki Linkli Robot Manipülatörün Modellenmesi ve Bozucu Etki Altında Yörünge Kontrolü

İLGEN, Sinan | DURDU, Akif | GÜLBAHÇE, Erdi | ÇAKAN, Abdullah

Bu çalışmada, iki linkli düzlemsel bir robot manipülatörün bozucu etki altında yörünge kontrolü yapılmıştır. ADAMS yazılımı vasıtasıyla manipülatörün sanal bir prototipi oluşturulmuştur. Ayrıca, sistem için gerekli olan kontrolcü tasarımı MATLAB/Simulink ortamında gerçekleştirilmiştir. Sistemin simülasyonu ise MATLAB ve ADAMS yazılımlarının eş zamanlı olarak çalıştırılması ile gerçekleştirilmiştir. Robot manipülatör iki giriş ve dört çıkışa sahiptir. Girişler, her iki eklemin tahriki için gerekli olan motor torkları, çıkışlar ise her iki eklemin açıları ve uç elemanın konumunun x-y bileşenleri ...Daha fazlası
