A new multi-bit quantizer for sigma delta modulators is proposed. The multi-bit quantizer has multiple single-bit quantizers, and the output of one of the single-bit quantizers is fed back to the input of another single-bit quantizer via a filter. Multi-bit quantization is achieved by averaging the outputs of the single-bit quantizers. Because of this architecture, the multi-bit quantizer realizes multi-bit quantization without external signals such as dithering signals that are needed in conventional architectures. The multi-bit quantizer allows for designing a new opamp-less multi-bit sigma delta modulator. The opamp-less multi-bit sigma delta modulator uses differential pairs for its loop filter instead of opamps that consume considerable power for high frequency applications. The opamp-less multi-bit sigma delta modulator is designed with a 90nm CMOS process. The achievable SNDR is 43dB with the bandwidth of 80MHz. The sampling frequency is 2.56GHz, and the power consumption of main analog parts is 15mA.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Editor's Notes
Multi-carrier: in multiple carrier per transponder mode, the transponder is assumed to work with sufficient global back off in order to guarantee linear operation. No additional degradation due to distortion is taken into account. Single carrier without predistortion: when a single carrier occupies a full transponder, it can be driven further into saturation (into the non-linear region). This will on one side increase the satellite output power (hence the achievable downlink C/N) while on the other side will also increase the degradation due to non-linearity. A balance between optimal IBO/OBO and resulting degradation needs to be found. The parameters in the output field can be used for this.Single carrier with predistortion: in order to overcome some of the degradation effects due to distortion, Newtec can enable Equalink™ predistortion on the modulator side. This allows to drive the transponder even further into saturation, effectively increasing the possible throughput. This mode is selected for non-linearized transponders.Single carrier in linearized transponder with predistortion: in order to overcome some of the degradation effects due to distortion, Newtec can enable Equalink™ predistortion on the modulator side. This allows to drive the transponder even further into saturation, effectively increasing the possible throughput. This mode is selected for linearized transponders which have a different IBO/OBO relationship compared to non-linearized transponders.
This value is used to determine the maximum occupied bandwidth a carrier is allowed to have. Traditionally, DVB carriers where allowed an occupied bandwidth equal to the transponder bandwidth (defined by the -1 dB points with typical values 36/54 and 72 MHz). With the advent of automatic linear predistortion (Equalink™) it is possible to extend the carrier bandwidth to the occupy the full allocated frequency slot of the transponder.
Allocated bandwidth: allows to enter the allocated bandwidth. From that (using the selected roll-off factor) the usable symbolrate and resulting info rate will be calculated.Baudrate: allows to enter the baudrate (symbolrate) of the carrier. From that (using the selected roll-off factor) the allocated bandwidth and resulting info rate will be calculated.Info rate: allows to enter the information rate. The information rate is the raw input rate at the modulator board so including the encapsulation overhead. From that the needed baudrate (using the selected modulation and coding) is calculated as well as the needed allocated bandwidth.
Select the modcod from the drop down that will be used on the carrier. Depending on the selected system and hardware the list will be updated to reflect only valid selections.Remark that all possible MODCODs are present in this drop-down list. However some MODCODs might be less efficient than higher MODCODs. For a selected list with only the optimal MODCODs, please refer to the table at the bottom of the sheet.
For the upcoming release of the MDM6100 which will also be able to carry transport streams without any encapsulation (MPEG frames are directly injected into baseband frames), the encapsulation can then be switched off.
No label: GSE label addressing is not added. Remote terminals will filter out the data for their destination using the ISI mechanism (which leads to a maximum of 255 channels).Short label (3 bytes): 3 hex bytes are used to address individual channels/terminals. This allows for the addressing of 224 =16 million channels. Additional overhead is about 0.75% (when working with iMix packet sizes).Long label (6 bytes): 6 hex bytes are used to address individual channels/terminals. This allows for the addressing of 248 = virtually unlimited number of channels. Additional overhead is about 1.5% (when working with iMix packet sizes)
iMix: this is a standard mix of a typical internet traffic. It contains an typical mix of VoIP, medium size http packets and large packets. Average packet size is 404 bytes.TSoIP (including RTP): This is used in case a TSoIP is transported over satellite as native IP without encapsulating the TS packets first. The most efficient case of 7 TS frames per IP packet is taken which implies an fixed IP packet size of 7*188 + 20 + 8 + 12 = 1356 bytes. More details in the section TSoIP overhead.TSoIP (excluding RTP): This is used in case a TSoIP is transported over satellite as native IP without encapsulating the TS packets first, also here the case if 7 TS frames per IP packets is considered which implies a fixed IP packet size of 7*188 + 20 + 8 = 1344 bytes. More details in the section TSoIP overhead.This field is not applicable when TS mode (TS over ASI or IP) is selected as the transport stream packets are directly encapsulated in DVB-S2 frames without any overhead.
The performance data is provided for a FER (Frame Error Rate) of 1E-7 or 1E-3 when available. FER corresponds to BER. However in DVB-S2, BER is not easily measure because in case of link errors complete frames will be dropped. The only indication possible in DVB-S2 is the Frame Error Rate. When doing performance measurements, often a Frame Error Rate of 1E-3 is used because that can be reached in an acceptable time, if measurements are done at FER 1E-7, the measurement cycle would be too long. Performance at 1E-7 is extrapolated from these measurements.
Es/No (=C/N+D)Energy per symbol over the noise density. This is the required Es/No threshold in dB for operation in the linear (multiple carrier per transponder) channel. In case the threshold is needed for single carrier per transponder operation, add the “non-linear degradation value” to set the target Es/No (C/N) in the link budget program. This value is also displayed as “C/N” in the right hand side column.
The info rate is often used in link budget programs (such as Intelsat’s LST5) and the encapsulation overhead is entered as an additional percentage
