On the hypercomplex numbers and normed division algebra of all dimensions: A unified multiplication
Authors: Singh Pushpendra , Gupta Anubha , Joshi Shiv Dutt
Published: December 2023

Mathematics is the mother of all the sciences, engineering and technology, and a normed division algebra of all finite dimensions is the mathematical holy grail. In search of a real three-dimensional, normed, associative, division algebra, Hamilton discovered quaternions that form a non-commutative division algebra of quadruples. Later works showed that there are only four real division algebras with 1, 2, 4, and 8 dimensions. This work overcomes this limitation and introduces generalized hypercomplex numbers of all dimensions that are extensions of the traditional complex numbers. The space of these numbers forms non-distributive normed division algebra that is extendable to all finite dimensions. To obtain these extensions, we defined a unified multiplication, designated as scaling and rotative multiplication, fully compatible with the existing multiplication. Therefore, these numbers and the corresponding algebras reduce to distributive normed algebras for dimensions 1 and 2. Thus, this work presents a generalization of $\mathbb{C}$ in higher dimensions along with interesting insights into the geometry of the vectors in the corresponding spaces.

A New Mobile RF Drive Test Application
Authors: Samani Siewe Darix
Published: December 2023

To enhance the quality of service (QoS) provided to users, network operators are compelled to continually refine their network infrastructure through the iterative process of drive testing. Drive testing is a method used to measure and assess the coverage, capacity, and QoS in a mobile radio network. However, the conventional paradigm governing drive testing, which entails the deployment of either radio frequency equipment or software solutions such as TEMS Investigation accompanied by GPS and an MS (Mobile Station), is marred by inherent limitations that hinder precision in data collection spatiality and necessitate a cumbersome use of multiple tools. In our work, we embark on a novel trajectory, anchoring our non-invasive drive test methodology  on the potency of a wearable device such as smart phones. Inspired by this, we design  an Android-based drive test platform that stands as a fulcrum of innovation. This platform consists primarily of a mobile application that acts as a measuring instrument, and an API to relay the data collected by the mobile application. This Android-based approach provides operators with heightened precision in both location determination and parameter measurements. Moreover, it streamlines service provisioning, eliminating the need for a range of complex tools, and instead offering a simple application-based solution. By adopting our mobile application, the drive testing process becomes adaptable to a variety of scenarios, including roads with high traffic density or narrow pathways. Our methodology signifies a significant step forward in improving resources-efficient drive testing process for operators.

Enhancement of Ultrasound Microbubble and Blood Flow Imaging using Similarity Measurement
Authors: Huang Chengwu
Published: December 2023

Recent advancements in ultrasound technologies, such as ultrasound localization microscopy and ultrafast ultrasound Doppler, have enabled high-definition imaging of microvasculature. However, detecting weak microbubble or blood flow signals amid strong background noise remains a challenge, particularly in deep tissues. This study aims to enhance the signal contrast of microbubble and blood flow by leveraging their distinct spatial-temporal coherence in comparison to undesired noise for robust microbubble detection and microvascular imaging. We propose to quantify the signal coherence based on similarity analysis of beamformed ultrasound microbubble/blood flow data within the plane wave imaging framework. A spatial pixel is considered more likely to be a true microbubble/blood flow signal with a higher level of similarity, which can be measured by either of the following methods: 1) spatially block-wise normalized cross-correlation between two compounded frames; 2) temporally normalized autocorrelation across multiple compounded frames; 3) normalized cross-correlation between two subsets of post-compounded frames; 4) normalized autocorrelation of the pre-compounded data across angular direction. The original microbubble/blood flow signal is then weighted by the similarity measurement on a pixel-by-pixel basis to generate images with an improved signal contrast. The robustness of the proposed methods was first demonstrated in both phantom experiments and in vivo microbubble data from kidney transplant. We further validated their feasibility in blood flow imaging without the use of microbubbles based on in vivo data of human liver and kidney. Significant contrast improvement was observed, facilitating better visualization and detection of both microbubble and noncontrast microflow signals, which indicates a great potential of the methods for improved microvascular imaging and widespread clinical translation.
Directivity of Radiating Quantum Source Systems
Authors: Mikki Said
Published: December 2023

We explore essential factors pertaining to the spatial directivity of quantum radiating source systems (QSSs), encompassing quantum antennas and quantum sensors. Our primary focus is on their capacity to control the emission of photons in specific spatial directions. We present a comprehensive definition of quantum directivity, drawing inspiration from Glauber’s photon detection theory. This definition closely parallels the framework of analogous concepts in classical antenna theory. By conducting thorough conceptual and mathematical analysis, we address the challenge of characterizing the directive properties of a general QSS. Essentially, our approach presents a computational model that relies solely on the radiation field operator’s density as input.
Artificial Intelligence in Governance: A Comprehensive Analysis of AI Integration and Policy Development in the German Government
Authors: Bodemer Oliver
Published: December 2023

In the intricate tapestry of modern governance, the role of technology, particularly Artificial Intelligence (AI), has become increasingly pivotal. Germany, renowned for its bureaucratic efficiency and technological innovation, stands at the crossroads of a significant transformation. This paper delves into the heart of this evolution, exploring how AI is being integrated into the German government’s operations.  

At present, Germany’s bureaucratic system, known for its precision and thoroughness, faces the universal challenges of modern governance: increasing complexity, demand for faster service delivery, and the need for cost-effective administration. In this context, AI emerges as a beacon of potential, promising to enhance efficiency, reduce bureaucratic bottlenecks, and enable more informed decision-making through data-driven insights.  

The investigation reveals that while Germany has made strides in digitizing its public services, the full integration of AI is still in its nascent stages. The potential benefits are manifold: from automated tax processing systems that promise greater accuracy and speed, to AI-driven public safety measures that can predict and prevent incidents before they occur. These advancements not only aim to streamline administrative processes but also enhance the citizen-government interface, making it more responsive and user-friendly.  

However, the journey is not without its challenges. Issues of data privacy, ethical considerations in AI deployment, and the need for robust regulatory frameworks are at the forefront of this technological shift. The study, through its methodical examination of two case studies, seeks to provide a comprehensive understanding of how AI can be harmoniously woven into the fabric of German governance, ensuring efficiency and innovation while upholding the values of transparency and accountability.  

In conclusion, the paper presents a detailed narrative of Germany’s current bureaucratic landscape and the transformative role AI could play, offering insights and recommendations for policymakers, technologists, and administrators alike. As Germany stands on the brink of this digital revolution, the lessons gleaned from this inquiry could well chart the course for a new era of governance.  
Reconstruction of the frequency-wavenumber spectrum of water waves with an airborne acoustic Doppler array for non-contact river monitoring
Authors: Krynkin Anton , Dolcetti Giulio , Alkmim Mansour , Cuenca Jacques , De Ryck Laurent , Sailor Gavin , Muraro Fabio , Tait Simon , Horoshenkov Kirill
Published: December 2023

This work presents a novel method to reconstruct the frequency-wavenumber spectrum of water waves based on the complex acoustic Doppler spectra of scattered sound measured with an array of microphones. The reconstruction is based on a first-order small-roughness-amplitude expansion of the acoustic wave scattering equation, which is discretized and inverted by means of a singular value decomposition. An analogy of this approach to the first-order Bragg scattering problem is demonstrated by means of a stationary phase expansion. The approach enables the reconstruction of the dispersion relation of water waves when the ratio between roughness height and acoustic wavelength is less than 0.1, and when the surface wavelength is larger than 1/2 of the acoustic wavelength. The method is validated against synthetic data and data from laboratory and field experiments, to demonstrate its applicability to two- and three-dimensional complex patterns of water waves, and specifically to the surface deformations that arise naturally in a turbulent open-channel flow. Fitting the reconstructed data with the analytical dispersion relation enables the non-contact estimate of the underlying flow velocity for hydraulic conditions where the coexistence of different types of turbulence-forced and freely propagating water waves would limit the accuracy of standard non-contact Doppler velocimetry approaches, paving the way for robust and accurate non-contact river monitoring using acoustics.

An Ultra Fast Settling and Low Area Bit Synchronizer Architecture
Authors: Ghosh Amitava , Dhar Anindya S.
Published: December 2023

The research is focussed on designing a bit synchronizer for wireless sensor node (WSN) applications and specifically Medical Implant Communications Service (MICS) band WSNs. The basic philosophy is that on receiving a 0-1 initial bit transition from the transmitter, the bit synchronizer is activated and it generates a strobe signal at bit time intervals from an initial latency. Two methods for latency calculation has been described. One is off-chip and another is on-chip. The bit synchronizer has ultra fast settling capability, ultra low power consumption and low silicon area. These requirements are a must for bit synchronizers in WSNs. A non-ideal model of a BFSK receiver has been designed in MATLAB and the bit synchronizer operation has been tested. Bit error ratio less than 10-3 has been obtained (WSNs have less stringent error ratios).
A Scene Boundary Detection Approach Using Audio Features
Authors: Akewar Mayur
Published: December 2023

Scene boundary detection is essential in video intelligence, video analytics, and video summarization. Cutting long videos into short meaningful and semantic scenes helps in applying video classification tasks and extracting useful information from the video. It’s a challenging task to extract meaningful scenes from the video. Previous work involved scene detection using camera angle change detection and subtitle text timestamps. This approach extracts tiny scenes that are irrelevant in many video intelligence applications that involve extracting long scenes such as video summarization video analytics and video content moderation. Here, we proposed an efficient scene-extracting mechanism using audio features that extract long and relevant scenes by identifying changes in audio features like speech, music, background audio, human voice, animal voice, etc. The proposed approach is efficient in terms of speed and extracting well-formed scenes.
Nonlinear Efficiency-Optimal Model Predictive Torque Control of Induction Machines
Authors: Becker Marius , Stender Marius , Wallscheid Oliver
Published: December 2023

Induction machines (IMs) are widely used in many applications, e.g., electric vehicles or industrial automation, which motivates efficiency-optimal operation for the sake of energy and cost savings. However, a loss-minimal IM control leads to reduced flux operation at partial load, i.e., achievable torque dynamics after load steps are physically limited due to the IM’s large rotor time constant. Hence, designing the IM torque control for minimal settling time is of particular importance to allow both an efficient and sufficiently dynamic drive operation. Against this background, a model predictive control (MPC) framework is proposed, which utilizes a precise model of the IM covering magnetic saturation, iron losses, skin effect and thermal influences. As this model is highly nonlinear, it is iteratively linearized along the predicted control trajectory so that a computationally efficient quadratic program can be defined for the MPC problem. To enable sufficiently long prediction horizons, a hierarchical control structure with the stator currents as the actuation variables of the model predictive torque control is utilized. Thanks to this scalable control approach, the proposed framework can be easily extended to multi-machine drive systems covering higher-dimensional problem spaces. Empirical tests validate the feasibility of the proposed approach both for single as well as multi-machine drive applications.
Evaluation of SiC MOSFET Key Parameters for Nanosecond Pulsed Field Ablation: Investigating Discrepancies Between Experimental Data and Manufacturer Datasheet Values
Authors: Zhu Kai , Shi Fukun , Guo Yuyi , Gong Jinling , Rao Junfeng , Zhuang Jie
Published: December 2023

Nanosecond pulsed field ablation (nsPFA) is a promising modality for clinical tissue ablation. The performance of the pulse generator (PG) strongly depends on the switching characteristics of the SiC MOSFET. Currently, many key parameters listed in SiC MOSFET datasheets are determined using double-pulse test circuits with inductive loads, whereas loads in nsPFA-applications are predominantly resistive. This study proposes a test scheme for SiC MOSFETs under nsPFA-like operating conditions. Key parameters to be evaluated are pulsed drain current (IDM), on-resistance (Ron), rise/fall time, turn-on/off delay, and minimum pulse width. The results show significant differences between manufacturer datasheet values and experimental data. For example, one switch under test has an Idm value of 40 A in the datasheet but 153 A in experimental test. This study recommends that custom testing of SiC MOSFETs is essential when designing PGs for nsPFA-applications.

Published: December 2023

In this paper, we develop an economic mechanism for the DSO to exploit the flexibility of the LEM and integrate it into the techno-economic framework for coordinated procurement of DF supported by the novel active network technologies, in this case SOPs. The LEM flexibility mechanism independently clears the LEM, while respecting the network constraints and optimizing network operation cost by leveraging it with the social welfare of the LEM participants. The coordinated procurement framework is based on the bi-level programming approach, where the lower level ensures unconditional clearing of the LEM bids and offers, while the upper level minimizes network operational cost, subject to network constraints and DF originating from all three types of flexibility (i.e., network, contracted, and LEM). Both, the mechanism and the framework can be applied by the DSO to ensure secure and economic network operation while facilitating LEM clearing in the independent manner. In the numerical study, the framework has been applied to IEEE 33-bus benchmark system, where we investigate the performance of the coordination method proposed, evaluate the value of the LEM flexibility mechanism to the DSO, and the value of the novel active network technology (i.e., SOP). Using realistic flexibility demand and supply data, the numerical study showed that the optimal utilization of network and LEM flexibilities can lead to the DSO contracted flexibility service to become unnecessary. While the estimated value of coordinated procurement of the LEM and DSO contracted flexibilities accounts for 26.6% of the network operation cost, technology supported procurement of the LEM flexibility only can reduce the original network operation cost almost twice (by 48.9%).

Published: December 2023

Chronic hyperglycemia in patients with Type 2 Diabetes Mellitus (T2DM) can cause damage to various organs, resulting in both microvascular and macrovascular complications that lead to an increased risk of cardiovascular disease. One of the markers that can detect vascular disorders is D-dimer levels. Fasting blood glucose (FBG) analysis in T2DM patients associated with D-dimer levels is important to know to be used as an indicator in connection with diabetes complications, especially vascular complications. This study aims to determine the correlation between D-dimer levels and FGB. The study was conducted in three hospitals in North Sulawesi province. The study population was T2DM patients (as evidenced by fasting blood glucose >126mg/dL) who examined themselves in the period January-June 2023. Samples were obtained using the total sampling method, where all populations that met the inclusion and exclusion criteria were used as participants. Ninety-four patients with T2DM (62 women and 32 men) were eligible to be participants in this study. Blood pressure, GDP and D-dimer were examined. Based on the results of the blood pressure examination, 40 participants suffered from hypertension and 54 participants did not. The average values of blood glucose, HbA1c and D-dimer levels in hypertensive and non-hypertensive participants are not much different. The results of the analysis using Spearman's rho showed that there was a moderate correlation between D-dimer levels and GDP (p=0.03, r=0.302). In conclusion, although there is a moderate correlation between D-dimer levels and fasting blood glucose levels, D-dimer is not recommended to be used as an indicator of complications in T2DM.

Nasal reconstruction is no longer just about filling in a nasal defect, it aims for an aesthetic and functional results. It is a three-dimensional reconstruction, restoring the mucosal plane, the osteo-cartilaginous architecture and the skin coverage to which Burget added a fourth dimension, the aesthetic result. Frontal flaps have been used for a very long time to repair nasal defects. Their popularity is mainly linked to their proximity to the recipient site, their good vascularization and especially the color and texture of the frontal skin which are significantly similar to those of the nasal skin. The frontal flap is the technique of choice in the reconstruction of full-thickness nasal tissue defects. We adopted the reconstruction by frontal flaps for the repair of multiple nasal defects, concerning multiple patients all treated at the plastic and aesthetic surgery department of the Mohammed VI University Hospital of Tangier over a period of 2 years going from March 2021 to March 2023. The goal of this study is to evaluate its contribution and answer the following question; What are the indications of using frontal flaps, its advantages and limitations in rhinopoiesis? and to draw practical recommendations regarding its use.

Published: December 2023

The large number of inductive loads used, namely 3-phase induction motors and welding machines, has caused a low power factor in the electrical system at PT. Sunrise Steel. In this industry there are 2 production sites for coated steel named Continous Galvalume Line 1 and Continous Galvalume Line 2. There are 6 transformers that supply power to the two places, but there are 2 transformers that have a very low power factor, where Transformer 1 (Continous Galvalume Line 2) a capacitor bank has been installed but the power factor is still low, which is 0.67 and Transformer 3 (Continous Galvalume Line 1) is 0.66. The addition of Capacitor Bank is of course very much needed to increase the value of the power factor in the two electrical systems. This research targets an increase in power factor to 0.98, where Transformer 1 (Continuous Galvalume Line 2) requires the addition of a 17.831 uF capacitor and Transformer 3 (Continous Galvalume Line 1) requires a 2948,81 uF capacitor using an automatic compensation technique. The compensation method used in both is the global compensation method, a capacitor will be installed on each main LVMDP. ETAP Power Station software is used to simulate the results of installing capacitor banks.
