Timing and spectral analysis of 2S 1417-624 during its 2018 outburst
(2021)
We investigate timing and spectral characteristics of the transient X-ray pulsar 2S 1417-624 during its 2018 outburst with NICER follow up observations. We describe the spectra with high-energy cut-off and partial covering ...
A Mathematical Formulation And Heuristic Approach For The Heterogeneous Fixed Fleet Vehicle Routing Problem With Simultaneous Pickup And Delivery
(2021)
This study considers a variant of the vehicle routing problem (VRP) called the heterogeneous VRP with simultaneous pickup and delivery (HVRPSPD). The HVRPSPD may broadly be defined as identifying the minimum cost routes ...
Electronic Structure of Cuprates in a Boson-Fermion Mixture Theory
(2021)
In a nearly-filled energy band where scattering of electrons is hampered, a pairing interaction between two electrons and quanta in a solid (e.g., phonons or spin-resonances or some other excitation of electronic origin) ...
Three in One Sensor: A Fluorometric, Colorimetric and Paper Based Probe for the Selective Detection of Mercury(Ii)
(2021)
In this work, a 3,4-ethylenedioxythiophene and tetrahydrophenazine based donor-acceptor-donor-type conjugated molecule was used for the first time as a turn-off fluorescence sensor for the detection of mercury (Hg2+) ions. ...
Comparison of Different Machine Learning Approaches to Detect Femoral Neck Fractures in X-Ray Images
(2021)
Femoral neck fractures are a serious health problem, especially in the elderly population. Misdiagnosis leads to improper treatment and adversely affects the quality of life of the patients. On the other hand, when looking ...
Prevention of urinary infection through the incorporation of silver-ricinoleic acid-polystyrene nanoparticles on the catheter surface
(2021)
Nosocominal infections associated with biofilm formation on urinary catheters cause serious complications. The aim of this study was to investigate the feasibility of the polyurethane (PU) catheter modified with tetracycline ...
Na Incorporation into Cu2ZnSnS4 Thin Film Absorbers from RF-Sputtered Naf Precursors
(2021)
In this work, we report the incorporation of sodium (Na) alkaline element into copper-zinc-tin-sulphide (Cu-Zn-Sn-S) precursor films by adding radio frequency (RF)-sputtered sodium fluoride (NaF) intermediate layers bringing ...
Multi-objective Optimization of Turning Parameters for SiC- or Al2O3-Reinforced Aluminum Matrix Composites
(2021)
This paper investigates the turning performance of particle-reinforced composite materials in terms of energy consumption and surface quality. The proposal of an experimental design approach pertinent to the optimization ...
Brain tumor prediction on MR images with semantic segmentation by using deep learning network and 3D imaging of tumor region
(2021)
When it comes to medical image segmentation on brain MR images, using deep learning techniques has a significant impact to predict tumor existence. Manual segmentation of a brain tumor is a time-consuming task and depends ...
System Identification for A Six-Storey Precast Concrete Frame Building
(2021)
This paper presents forced and ambient vibration tests on a six-storey precast concrete frame building, a structural system that has not often been the focus of such tests in spite of its widespread use. Precast buildings ...
