Studer’s popular Vista 5 console gets an upgrade to the M2 with the optional addition of the precision TFT metering system introduced on the flagship Vista 9 console.
The new metering is capable of displaying signal levels from mono through to 5.1 channels on each input, with a configurable lower area which can be used to display bus assignments, surround images or the unique History mode, where a scrolling audio waveform displays signal anomalies and highlights them for up to 50 seconds to allow the engineer to identify where the event occurred. Metering for ‘layer 2’ signals can also be viewed, while the Control Bay screen can be used to provide configurable user pages with up to 40 meters.
When the TFT meter bridge is fitted, the external GC screen becomes an integral part of the chassis.
The Vista 5 M2 is based on the well known and widely praised Vista 5 console, which has found its home in all kinds of broadcast and theater production facilities around the world, and existing Vista 5 owners will be pleased to learn that their console may be easily upgraded to the M2 version to be ready for the optional meter bridge, which is a simple add-on to the console chassis.
Available in two frame sizes, 32 and 42 fader, the Vista 5 M2 brings precision signal monitoring to an already versatile and highly-regarded console.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
Redefining brain tumor segmentation: a cutting-edge convolutional neural netw...IJECEIAES
Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical

A SYSTEMATIC RISK ASSESSMENT APPROACH FOR SECURING THE SMART IRRIGATION SYSTEMSIJNSA Journal
The smart irrigation system represents an innovative approach to optimize water usage in agricultural and landscaping practices. The integration of cutting-edge technologies, including sensors, actuators, and data analysis, empowers this system to provide accurate monitoring and control of irrigation processes by leveraging real-time environmental conditions. The main objective of a smart irrigation system is to optimize water efficiency, minimize expenses, and foster the adoption of sustainable water management methods. This paper conducts a systematic risk assessment by exploring the key components/assets and their functionalities in the smart irrigation system. The crucial role of sensors in gathering data on soil moisture, weather patterns, and plant well-being is emphasized in this system. These sensors enable intelligent decision-making in irrigation scheduling and water distribution, leading to enhanced water efficiency and sustainable water management practices. Actuators enable automated control of irrigation devices, ensuring precise and targeted water delivery to plants. Additionally, the paper addresses the potential threat and vulnerabilities associated with smart irrigation systems. It discusses limitations of the system, such as power constraints and computational capabilities, and calculates the potential security risks. The paper suggests possible risk treatment methods for effective secure system operation. In conclusion, the paper emphasizes the significant benefits of implementing smart irrigation systems, including improved water conservation, increased crop yield, and reduced environmental impact. Additionally, based on the security analysis conducted, the paper recommends the implementation of countermeasures and security approaches to address vulnerabilities and ensure the integrity and reliability of the system. By incorporating these measures, smart irrigation technology can revolutionize water management practices in agriculture, promoting sustainability, resource efficiency, and safeguarding against potential security threats.

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024Sinan KOZAK
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.

32. 3 Replace Fan Unit
The fan can be replaced during normal operation. It is recommended to
complete the replacement of the fan within 10 minutes to not overheat the AIR
unit.
Warning!
When working at height, there is a risk of falling objects. Falling objects can cause
serious injury or even be fatal. Always wear a helmet and avoid standing in an area
where objects can fall.
3.1 RF Safety Guidelines when Replacing Fan Module
The AIR 32 product has been tested in accordance with relevant technical
standards to determine the RF safety limit compliance boundary for
standalone operation. A compliance boundary is the volume around the
product outside of which the RF exposure is below applicable limits.
Information about RF electromagnetic field exposure and compliance
boundaries for this product is provided in Radio Frequency Electromagnetic
Exposure.
For the configurations tested by Ericsson, the compliance boundary for
occupational exposure extends 0 cm behind the AIR 32 product. This means
that fan unit replacement work can be conducted behind the product. For other
configurations than those tested or for markets with exposure limits different
from the international limits applied in the tests, the RF safety limit compliance
boundary need to be determined before the work is commenced.
