Description:
The 6NPM is a very high efficiency, (101.8 dB 1watt / 1 meter) 6-inch midrange speaker with incredibly linear frequency response characteristics and ultra low harmonic distortion artifacts. The 6NPM has extremely high sound quality. The 6NPM uses a lightweight paper pulp, specifically developed for this application. This unique cone provides the ideal weight to strength ratio.
At the core of the 6NPM is it’s voice coil technology featuring edge wounded aluminum ribbon wire. Unique lightweight and very short former provides the ideal transfer of power between the voice coil and the cone assembly and assists in reducing the distortion artifacts. By combining this material with the state of the art adhesives, the 6FPM delivers incredible performance. The magnetic circuit design is optimized to generate the minimum amount of flux modulation, providing exceptional stability. The neodymium magnet is in a direct contact with the CNC exposed aluminum section of the basket, hold in place by our thermal transfer adhesives. This design dramatically improves the heat transfer. The 6NPM is ideal for use in both sealed and vented enclosure designs. The most suitable applications are in high quality professional audio, as line array systems, 3-way designs, where extreme SPL outputs are desired. The 6NPM can be horn loaded or used in directly radiated midrange applications.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

(*2) Maximum continuous output current on VA+ and VA- is in sum 600mA. This allows for any
load combination between the two outputs in total giving 600mA, i.e at most 600mA on
one and 0mA at the other. If these outputs are shorted a fuse resistor (R209) blows and
has to be replaced. See below for details.

THD vs power both channels driven and single channel driven
Anaview is here showing the THD vs power measurement with two channels driven and
one channel driven. The reason for this is that in applications where both channels are
driving similar loads, like in a stereo amplifier, the power supply is loaded by both
channels and therefore limits how much total power that can be output. In an active 2-
way speaker, which is quite a common application, only one channel drives a heavy load
(the bass driver) and the other channel delivers a significantly lower RMS-power into the
tweeter.
Both channels driven (stereo applications) and BTL

APPLICATION NOTES
Optimizing input stage CMRR
This is simplified drawing of the input of AMS0100. It is a typical circuit used where the
source impedance is well known and does not vary too much. Input current are
calculated when a balanced signal is applied. As can be seen the input impedance is not
the same on both inputs and depending on which type of signal is applied (single ended
or balanced) the input impedance changes.
This is however not a problem as long as a few precautions are made. Common mode
rejection CMRR will be significantly improved by having the same source resistance on
both the inputs.
Impedance balancing with single ended signal
Below is shown a setup with an impedance balanced single ended source. This requires a
balanced cable.
It is quite common to have a series resistance of 50ohm or more on the signal output so
if the same resistance is placed in the opposite side of the signal of either sending or
receiving side of the cable the CMRR rejection is intact.

Balanced input signal
If a balanced signal source is used the following setup applies.
If long cables are used the cable impedance itself can contribute a lot to the series
impedance and since that impedance is not very well defined (symmetrically) it can be an
advantage to increase both the diff mode and common mode input impedance. In such a
case an additional circuit as below can be added before the AMS module.
