Fabrication of Dish-Shaped Micro Parts by Laser Indirect Shocking Compound Process

open access: yesMicromachines, 2016
Compound process technology has been investigated for many years on a macro scale, but only a few studies can be found on a micro scale due to the difficulties in tool manufacturing, parts transporting and punch-die alignment.

The Effect of Intermittent Signal on the Performance of Code Tracking Loop in GNSS Receivers

open access: yesJournal of Electrical and Computer Engineering, 2011
This paper analyzes the code tracking performance in the presence of signal blanking in Global Navigation Satellite System (GNSS). The blanking effect is usually caused by buildings that obscure the signal in either a periodic or random manner.

Galling-Free Fine Blanking of Titanium Plates Using Carbon-Supersaturated High-Speed Steel Punch

open access: yesC, 2023
A carbon-supersaturated (CS-) high-speed steel punch was prepared using low-temperature plasma carburizing for fine blanking of pure titanium plates. The bare high-speed steel punch was also prepared as a reference to describe the adhesion and abrasive ...

Demonstration of wavelength packet switched radio-over-fiber system [PDF]

open access: yes, 2007
The authors present a novel concept of employing optical wavelength packet switching in radio-over-fiber access networks. In such a system, the tunable laser (TL) would be employed as a transmitter in the central station. The optical carrier generated by

Effect of the individual layer thickness and relative blanking clearance on micro-blanking for Cu/Nb multilayer composite sheets [PDF]

open access: yesMATEC Web of Conferences
In this study, two types of Cu/Nb multilayer composite sheets with individual layer thicknesses of 11.11 μm and 0.35 μm, respectively, were first prepared and then tested by micro-blanking.

Roseomics: a blank slate [PDF]

open access: yesCurrent Opinion in Virology, 2014
Recent technological advances have led to an explosion in the system-wide profiling of biological processes in the study of herpesvirus biology, herein referred to as “-omics”. In many cases these approaches have revealed novel virus-induced changes to host cell biology that can be targeted with new antiviral therapeutics.

Analysis of GFDM as a robust 5G communication technique in noisy environment [PDF]

open access: yes, 2020
One of the challenges of modulation techniques used in Fifth-Generation (5G) is their robustness in noisy environment. Conventional Orthogonal Frequency Division Multiplexing (OFDM) cannot be considered as a 5G waveform in its original form because of ...
