Cryptographic security concerns on timestamp sharing via a public channel in quantum-key-distribution systems
(American Physical Society, 2022-07)Quantum-key-distribution protocols are known to be vulnerable against a side channel attack that exploits the time difference in detectors' responses used to obtain key bits. The recommended solution against this timing ... -
CSSTag: optical nanoscale radar and particle tracking for in-body and microfluidic systems with vibrating graphene and resonance energy transfer
(IEEE, 2017-12)Biological particle tracking systems monitor cellular processes or particle behaviors with the great accuracy. The emissions of fluorescent molecules or direct images of particles are captured with cameras or photodetectors. ... -
Current balancing circuit design for parallel LED strings in QDOT high bright TV with dual-transformer LLC resonant topology
(IEEE, 2022)New LED technologies demand slim designs with increased backlight power. When the parallel-connected LED strings are driven by multiple transformers, the magnetic coupling difference and the LED string voltage difference ... -
Curriculum learning for face recognition
(IEEE, 2021)We present a novel curriculum learning (CL) algorithm for face recognition using convolutional neural networks. Curriculum learning is inspired by the fact that humans learn better, when the presented information is organized ... -
A custom brace design to connect a user limb to an exoskeleton link with minimal discomfort
(IEEE, 2021)Exoskeletons are increasingly helping people with different applications. Regardless of what they were built for, exoskeletons have a common discomfort problem from the misalignment of robot and human joints. In this paper, ... -
A custom-design atmospheric channel emulator for the performance evaluation of free space optical communication systems
(IEEE, 2017)In this paper, we present our custom design atmospheric channel emulator for free space optical (FSO) system evaluations in a controlled environment. Our emulator is in the form of an atmospheric chamber with dimensions ... -
CWT-DPA: Component-wise waiting time for BC-enabled data plane authentication
(Elsevier, 2022-11-24)Software-Defined Networking (SDN) is a promising networking paradigm that brings central management and network programmability to improve existing networking systems. However, SDN has several security threats due to its ... -
Cyclic deformation response of ultra-fine grained titanium at elevated temperatures
(Elsevier, 2019-05)This study focuses on the high-temperature cyclic deformation response (CDR) of ultra-fine grained (UFG) titanium of commercial purity (grade 4) processed via equal channel angular extrusion as a severe plastic deformation ... -
Cyclic delivery schedules for an inventory routing problem
(Informs, 2015-11)We consider an inventory routing problem where a common vendor is responsible for replenishing the inventories of several customers over a perpetual time horizon. The objective of the vendor is to minimize the total cost ... -
Cyclic ordering policies from capacitated suppliers under limited cycle time
(Elsevier, 2019-02)In this paper, we study the ordering policy of a manufacturer/retailer which procures a single item from multiple capacitated suppliers and satisfies an exogenous deterministic and constant demand. Manufacturer's objective ... -
Çevik yöntemlerde cosmic i̇şlev puanı ve hikaye puanının birlikte kullanımı
(CEUR-WS, 2017)Hikaye Puanı (SP: Story Point), Scrum ve Kanban gibi çevik yöntemlerde kullanılan en yaygın metriklerden birisidir. Subjektif bir metrik olsa da kullanışlı ve basit olması nedeniyle çevik ekiplerin birikim listelerinde ... -
Çimento-esaslı harçlarda kendiliğinden iyileşmenin sağlanması için 2 bileşenli biyolojik katkı maddesinin geliştirilmesi
(Gazi Üniversitesi, 2021)Purpose: Throughout the literature, studies showed that among several alternatives such as diatomaceous earth (DE), metakaolin, zeolites and expanded clay could be suitable for protection of the bacteria based on their ... -
D0-meson RAA in PbPb collisions at √sNN = 5.02 TeV and elliptic flow in pPb collisions at √sNN = 8.16 TeV with CMS
(Elsevier, 2019-02)The study of charm production in heavy-ion collisions is considered an excellent probe for the properties of the hot and dense medium created in heavy-ion collisions. Measurements of D-0-meson nuclear modification factor ... -
Dağıtık bir openflow kontrol birimi mimarisi
(IEEE, 2012)Considering the modern internet traffic rates, the network architecture is of particular importance as the running services itself. On the other hand, due to the increasing complexity and black-box structure of the available ... -
DAPNA: an architectural framework for data processing networks
(Springer Science+Business Media, 2013)A data processing network is as a set of (software) components connected through communication channels to apply a series of operations on data. Realization and maintenance of large-scale data processing networks necessitate ... -
Darbe i̇şaretleri̇ i̇çi̇n aşırı-hızlı FPGA tabanlı eǧri̇ beti̇mlenmesi̇
(IEEE, 2012)Bu çalışmada anlatılan donanım 1.5 GHz Analog-Sayısal- Çevirici’den gelen darbe işaret dizisini işleyebilmekte ve darbe işaretlerini genlik, yükselme/düşme süresi ve varış zamanı parametreleriyle özetleyebilmektedir. Söz ... -
Data model extension impact analysis
(IEEE, 2021)Relational database schemas are subject to change. For instance, columns of a table can be modified, deleted or extended. These changes have an impact on the source code that utilizes the corresponding table. They also ... -
Data stream analytics and mining in the cloud
(IEEE, 2012)Due to prevalent use of sensors and network monitoring tools, big volumes of data or “big data” today traverse the enterprise data processing pipelines in a streaming fashion. While some companies prefer to deploy their ... -
Data-driven bandwidth prediction models and automated model selection for low latency
(IEEE, 2021)Today's HTTP adaptive streaming solutions use a variety of algorithms to measure the available network bandwidth and predict its future values. Bandwidth prediction, which is already a difficult task, must be more accurate ... -
A data-driven matching algorithm for ride pooling problem
