Analysis of a GaN based PWM AC-AC Converter with an Improved Switch Loss Model
(Kırşehir Ahi Evran Üniversitesi, 2021)
AC-AC converters have a wide range of use in industrial applications mostly with installed silicon switches. In
last decade, GaN’s are served to market with their high efficiency and fast on-off times, hence implementation ...
The Impact of Aging and Drag-Finishing on The Surface Integrity and Corrosion Behavior of The Selective Laser Melted Maraging Steel Samples
(Wiley-VCH GmbH, 2021)
The maraging steel components fabricated using the selective laser melting process exhibit remarkable static strength. However, high pore density and large surface imperfections impede their overall mechanical and chemical ...
The Interrelationship of Attachment Style, Sense of Loneliness, and Social Dissatisfaction in Children Aged 60–72 Months
(Springer, 2020)
The aim of this correlational survey-based research is to examine the relationships between the attachment styles of children aged
60–72 months and their senses of loneliness and social dissatisfaction. The participants ...
A Study on the Effects of Different Heat-Treatment Parameters on Microstructure–Mechanical Properties and Corrosion Behavior of Maraging Steel Produced by Direct Metal Laser Sintering
(Wiley, 2020)
Herein, direct aging (aged‐490 °C/6 h) and solution heat treatment and subsequent aging (SHT‐940 °C/2 h + 490 °C/6 h) heat treatments are applied to maraging steel (MS1) produced by direct metal laser sintering (DMLS) ...
A Comprehensive Approach to Analyze the Discrepancies in Heat Transfer Characteristics Pertaining to Radiant Ceiling Heating System
(Elsevier, 2021)
Radiant heating/cooling systems are being popular thanks to their ability of regulating the living-environment
with the use of low temperature heating and high temperature cooling. In this work, an artificial neural
network ...
Investigation of Direct Metal Laser Sintering Downskin Parameters’ Sagging Effect on Microchannels
(Springer, 2021)
Additive manufacturing technology is an innovative and advantageous production technology in producing microchannels, heat
exchangers designed in complex geometries. Process parameters developed to provide production ...
Quasi–Minimal Surfaces of Pseudo–Riemannian Space Forms with Positive Relative Nullity
(Elsevier, 2020)
In this paper, we consider surfaces in 4–dimensional pseudo–Riemannian space–forms with index 2. First, we obtain some of geometrical properties of such surfaces considering their relative null space. Then, we get ...
Influence of the Post-Processing Operations on Surface Integrity of Metal Components Produced by Laser Powder Bed Fusion Additive Manufacturing: a Review
(Taylor & Francis Group, 2021)
As industries are increasingly adopting the laser powder bed
fusion (LPBF) additive manufacturing (AM) process, it is crucial
to understand the process closely and to find ways to improve
the final quality of the finished ...
rGO / MnO2 / Polyterthiophene Ternary Composite: Pore Size Control, Electrochemical Supercapacitor Behavior and Equivalent Circuit Model Analysis
(Springer, 2020)
In this work, a new electrode active materials including reduced graphene oxide (rGO), Manganese dioxide (MnO2) /
polyterthiophene (PTTh) has been synthesized as a nanocomposite using in-situ polymerization method, ...
A Portable Wearable Tele-ECG Monitoring System
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
This paper introduces a wearable Tele-ECG and heart rate (HR) monitoring system which has a novel architecture including a stretchable singlet redesigned with textile electrodes (TEs), textile threads, snap fasteners, ...
