Continuous butanol fermentation with submerged ceramic membranes

Introduction. Building block chemicals, such as butanol, can be produced via fermentation and biobased feedstocks as a more sustainable alternative compared to the current petrochemical methods. However, the butanol fermentation is subjected to low product titres (<20 g/L) due to product inhibition of the bacteria [1]. To overcome this continuous fermentation can be applied, as it offers considera

Intensified butanol production through optimisation of integrated membrane bioreactor operation

Fermentation intensification is crucial for the economic viability of biobased chemical production through fermentative routes, including a shift from batch/fed-batch to continuous fermentations to enhance volumetric productivity. This is especially relevant for the Acetone Butanol Ethanol (ABE) fermentation due to low productivities and concentrations caused by product toxicity. However, transiti

Advancing Software Monitoring : An Industry Survey on ML-Driven Alert Management Strategies

With the dynamic nature of modern software development and operations environments and the increasing complexity of cloud-based software systems, traditional monitoring practices are often insufficient to timely identify and handle unexpected operational failures. To address these challenges, this paper presents the findings from a quantitative industry survey focused on the application of Machine

Asynchronous vs Synchronous SAR ADCs - Performance Beyond Nominal Speed

This paper presents a comparison between a Itl-bit asynchronous SAR (ASAR) ADC and a 10-bit synchronous SAR (SSAR) ADC, both designed and simulated in a 22-nm FDSOI CMOS process. To further support the simulation results, the ASAR ADC has also been fabricated and measurements are pre-sented. As opposed to the abrupt SNDR collapse in the SSAR ADC, the SNDR of the ASAR ADC shows a more graceful deg-

Unveiling the Mechanisms Behind Temperature-Dependent Impedance Behavior in Polymer Electrolyte Fuel Cells at High Current Loads

Positioning Polymer Electrolyte Fuel Cells (PEFCs) in the market depends on substantial advances that start from a deep knowledge concerning the influence of operating parameters, such as temperature-sweep and high-current density. In the present study, a comprehensive analysis of the impedance behavior of a single PEFC via Electrochemical Impedance Spectroscopy (EIS) was carried out in order to u

UAV-electromagnetic measurements to map variations of depth to bedrock in southern Sweden

In the context of an infrastructure project UAV-electromagnetic measurements at five areas in southern parts of Sweden are conducted to study the variation of depth to the bedrock. The source signals are the distant radio transmitters in the band 15-350 kHz. The example shown in this work is from Area 5 where the underlying bedrock is a gneissic granite with reasonably high resistivity. The resist

QT-RR Adaptation Time Lag Estimation and its Dependence on Heart Rate Trend Frequency Content in Exercise Stress Testing

A new model for the estimation of the QT-RR adaptation time lag using exercise ECG stress testing has been proposed, assuming a linear heart rate trend during the test. In this work, simulated ECGs have been generated based on heart rate patterns with oscillations at different frequencies to demonstrate that the assumption can be relaxed so that the QTRR adaptation time lag can be adequately estim

Circularly polarized sub-THz antenna design for distributed deployment

Sub-THz deployment is challenging due to high propagation losses, necessitating dense deployment. To reduce cost, RF signal can be distributed via plastic fiber to remote radio units to increase coverage area. In this paper, we propose an antenna-in-package concept for the single-layer substrate on low-cost embedded wafer level ball grid array (eWLB) packages. To suppress the distortion in the bro

Leveraging Deep Learning for Approaching Automated Pre-Clinical Rodent Models

We evaluate deep learning architectures for rat pose estimation using a six-camera system, focusing on ResNet and EfficientNet across various depths and augmentation techniques. Among the configurations tested, ResNet 152 with default augmentation provided the best performance when employing a multi-perspective network approach in the controlled experimental setup. It reached a Root Mean Squared E

Noisy One-Point Homographies are Surprisingly Good

Two-view homography estimation is a classic and fundamental problem in computer vision. While conceptually simple, the problem quickly becomes challenging when multiple planes are visible in the image pair. Even with correct matches, each individual plane (homography) might have a very low number of inliers when comparing to the set of all correspondences. In practice, this requires a large number
