Cover glass behavior in handheld device drop: modeling; validation and design evaluation
Cover glass reliability performance in a drop test is critical for handheld electronic devices. Handheld device drop test has limitations in measuring dynamic response on the device components which complicates the test control and data ana...
Challenges in setting up and analyzing a multi-stress accelerated test
Planning a viable Multi-stress Accelerated Test can be a good challenge. It should start with the objective of the accelerated test being identified. It might be to estimate life, identify the main failure modes or mechanisms, or perhaps th...
An accelerated on-wafer test to improve long-term reliability of a 0.25 μm PHEMT process
Performance walkout is a phenomenon observed in AlGaAs/GaAs PHEMTs (Pseudomorphic High Electron Mobility transistors) which can adversely affect the long term reliability of devices that have applications in power amplifier design [5]. Temp...
Accelerated stress & reliability testing for software and cyber-physical systems
This paper considers the topic of accelerated testing of cyber-physical systems and software. It compares the testing of these systems to each other and to classical mechanical/electro-mechanical systems. The impact of the software (and com...
Accelerated life testing of a commercial door handle
This paper describes the test methodology, execution, and analysis of an accelerated life test (ALT) of a commercial door handle design (Fig. 1.). ALT is used to force failures to occur in less time by applying increased stresses to the com...
Railway Network Evolution Why it is urgent to wait for 5G?
The 3GPP 5G standard is almost ready. If its first phase, completed in 2018, allows this standard to claim its 5G status, it will become totally standardized after the second round of standardization completed at the end of 2019. The 5G sta...
A Frame Design for MIMO UW based Systems: Overhead Analysis & Channel Estimation
In this paper, we extend the conventional single-input-single-output unique word (UW) based frame designs to MIMO applications with spatial multiplexing. Considering a doubly-dispersive channel where the channel is varying both in time and ...
Dielectric Material Characterization for 5G Propagation Modelling
In this paper, a technique for the characterization of the complex permittivity of flat material panels is presented. Using broadband horn antennas and a simple measurement process, the permittivity and dielectric loss tangent of the materi...
Tractable Scheduling Algorithms for Self-Backhaul in 5G Networks
We consider the problem of scheduling 5G wireless networks with self-backhaul. The key difficulty is coordinating the transmissions on the backhaul and access links since a node cannot transmit and receive at the same time. A well-known sol...
Impact of Bandwidth Part (BWP) Switching on 5G NR System Performance
Bandwidth Parts (BWPs) is a 5G NR feature introduced in 3GPP Release 15 for dynamically adapting the carrier bandwidth and numerology in which a UE operates. BWP allows supporting multiple services per carrier, e.g. eMBB and mMTC. Although ...
