Needle localization using gabor filtering in 2D ultrasound images
(IEEE, 2014)In the percutaneous needle procedures using ultrasound (US) imaging, the needle should be detected precisely to avoid damage to the tissue and to get the samples from the appropriate site. Excessive artifacts and low ... -
NEEL: The nested complex event language for real-time event analytics
(Springer International Publishing, 2011)Complex event processing (CEP) over event streams has become increasingly important for real-time applications ranging from health care, supply chain management to business intelligence. These monitoring applications submit ... -
Negotiation for incentive driven privacy-preserving information sharing
(Springer International Publishing, 2017)This paper describes an agent-based, incentive-driven, and privacy-preserving information sharing framework. Main contribution of the paper is to give the data provider agent an active role in the information sharing process ... -
Network topology modulation for energy and data transmission in internet of magneto-inductive things
(IEEE, 2016)Internet-of-things (IoT) architectures connecting a massive number of heterogeneous devices need energy efficient, low hardware complexity, low cost, simple and secure mechanisms to realize communication among devices. One ... -
Network-coded cooperative systems in cognitive radio networks
(IEEE, 2022-12)We study the performance of a network-coded cooperative (NCC) system in an underlay cognitive radio network (CRN). The primary network (PN) consists of a single transmitter-receiver pair, and the secondary network (SN) is ... -
Network-coded cooperative systems with generalized user-relay selection
(IEEE, 2020-11)We consider a network-coded cooperative (NCC) system that consists of N >= 2 sources, M >= 1 decodeand-forward (DF) relays, and a single destination. The relays perform network coding (NC) on the received sources' symbols ... -
Neural network based digital pre-distorter design for DCO-OFDM visible light communications
(IEEE, 2022)Direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM) is an appealing modulation scheme for reliable, high-speed optical transmissions and foreseen to be used in the upcoming IEEE 802.11bb ... -
A new application of the traveling salesman problem: The Turkish cashier problem
(Ministry Communications & High Technologies Republic Azerbaijan, 2022)We define the problem of finding a route for the cashier that minimizes the cost of transportation as the Turkish Cashier Problem (TCP). It is a special case of the well-known traveling salesman problem. To solve the TCP, ... -
A new boson with a mass of 125 GeV observed with the CMS experiment at the large hadron collider
(American Association for the Advancement of Science, 2012-12-21)The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would ... -
A new calibration method for charm jet identification validated with proton-proton collision events at √s = 13 TeV
(IOP Publishing, 2022-03-17)Many measurements at the LHC require efficient identification of heavy-flavour jets, i.e. jets originating from bottom (b) or charm (c) quarks. An overview of the algorithms used to identify c jets is described and a novel ... -
A new control plane for 5G network architecture with a case study on unified handoff, mobility, and routing management
(IEEE, 2014-11)The tremendous growth in wireless Internet use is showing no signs of slowing down. Existing cellular networks are starting to be insufficient in meeting this demand, in part due to their inflexible and expensive equipment ... -
A new deep learning restricted boltzmann machine for energy consumption forecasting
(MDPI, 2022-08)A key issue in the desired operation and development of power networks is the knowledge of load growth and electricity demand in the coming years. Mid-term load forecasting (MTLF) has an important rule in planning and ... -
A new LED response model and its application to pre-equalization in VLC systems
(IEEE, 2021-09-01)With the growing interest in visible light communication (VLC), it is desired to transmit data at very high rates despite the LED's bandwidth becoming a bottleneck. The bandwidth of a white LED usually ranges between ... -
A new methodology to determine the design sensitivity of critical automotive body joints for basic design cycle
(Sage, 2019-09)As a result of more stringent requirements for improved fuel economy and emissions, there has been an increasing research activity to make vehicles lighter weight under some predetermined structural performance targets ... -
A new model for predicting the required pressure difference for pressure swirl atomizers
(Europe, Institute for Liquid Atomization and Spray Systems, ILASS, 2020)Prior to this study an investigation is made to analyze the accuracies of the semi-empirical correlations of the previous studies by comparing them with a large number of experimental data which is extracted from the works ... -
A new voltammetric sensor for penicillin G using poly(3-methylthiophene)-citric acid modified glassy carbon electrode
(Elsevier, 2022-10)In this study, an effective voltammetric sensor was developed for determination of penicillin G by electropolymerization of 3-methylthiophene with citric acid on glassy carbon electrode. Penicillin G selective electrode ... -
Next generation M2M cellular networks: challenges and practical considerations
(IEEE, 2015-09)In this article we present the major challenges of future machine-to-machine (M2M) cellular networks such as spectrum scarcity, and support for a large number of low-power, lowcost devices. As an integral part of the future ... -
Next-day operating room scheduling with time-dependent stochastic surgery durations
(Springer, 2022)Operating rooms (ORs) are the most costly part of hospitals, thus a priority for hospital administrations. In this paper, we consider the next-day OR scheduling problem for multiple operating rooms. We assume that surgeries ... -
Next-day operating room scheduling with uncertain surgery durations: Exact analysis and heuristics
(Elsevier, 2020-10-01)Operating rooms are units of particular interest in hospitals as they constitute more than 40% of total expenses and revenues. Managing operating rooms is challenging due to conflicting priorities and preferences of various ... -
