Characterization of Qubit Control Pulse Distortions in Superconducting Quantum Hardware

Input qubit control signals from an arbitrary waveform generator (AWG) operating at room temperature undergo linear dynamical distortions as it traverses various electrical components on the control line connecting to the quantum device. <br/>If uncompensated for, such distortions can have detrimental effects on gate performance, affecting...

Density and level-set based topology optimization for structural vibration problems: A comparative study

High performance machines rely on fast moving parts and generally avoid resonance for improved accuracy. To improve the dynamic properties of these high performance machines, their parts are optimized via a lengthy iterative process. Topology optimization for vibrations problems could shorten this time consuming design process and provide a more...

Including service information in a topological comparison of metro networks worldwide: A comparison of 51 metro networks worldwide using GTFS static data

Public transport (PT) plays a vital role in commuting billions of travellers in cities all over the world, providing a mode that is both sustainable and accessible. Metro networks are especially apt at this considering their high-capacity and high-speed operation in urban environments. Comparing different metro networks to one another is a...

Comparison Studies of Estimators for the Generalized Gamma Distribution and New Findings

The Generalized Gamma Distribution (GGD) is a three-parameter distribution with desirable properties. For certain values of the parameters, the GGD can reduce to the gamma, exponential and lognormal distribution, among others. This makes it a flexible distribution that can be used in various scenarios. The problem with implementation of the GGD...

Consolidating Gauge, Weather Radar and GPM DPR Level 2A Observations of High-intensity Rainfall Events in the Netherlands

The Dual-Frequency Precipitation Radar on board the Global Precipitation Measurement (GPM) mission core satellite has been providing precipitation products across the globe for over 6 years, thereby even supplying precipitation estimates for areas on Earth where surface-based precipitation measurements are not possible, like in remote regions,...

Differences Between MR Brain Region Segmentation Methods: Impact on Single-Subject Analysis

For the segmentation of magnetic resonance brain images into anatomical regions, numerous fully automated methods have been proposed and compared to reference segmentations obtained manually. However, systematic differences might exist between the resulting segmentations, depending on the segmentation method and underlying brain atlas. This...

Which error detection tool to choose?

The amount of data being collected is growing exponentially, both in academics as well as in business. Unfortunately, the quality of that data can be poor, leading to poor decisions and increasing costs. Data cleaning, the process of detecting and correcting errors from a dataset, could be the solution to improve bad data.<br/>This research...
