Hard SyDR: A Benchmarking Environment for Global Navigation Satellite System Algorithms
Authors: Grenier Antoine , Lei Jie , Damsgaard Hans Jakob , Quintana-Ortí Enrique S. , Ometov Aleksandr , Lohan Elena Simona , Nurmi Jari
Published: January 2024

A Global Navigation Satellite System (GNSS) is widely used today for both positioning and timing purposes. Many distinct receiver chips are available as Application-Specific Integrated Circuit (ASIC)s off-the-shelf, each tailored to the requirements of various applications. These chips deliver good performance and low energy consumption but offer customers little-to-no transparency about their internal features. This prevents modification, research in GNSS processing chain enhancement (e.g., application of Approximate Computing (AxC) techniques), and design space exploration to find the optimal receiver for a use case. In this paper, we review the GNSS processing chain using SyDR, our open-source GNSS Software-Defined Radio (SDR) designed for algorithm benchmarking, and highlight the limitations of a software-only environment. In return, we propose an evolution to our system, called Hard SyDR to become closer to the hardware layer and access new Key Performance Indicator (KPI)s, such as power/energy consumption and resource utilization. We use High-Level Synthesis (HLS) and the PYNQ platform to ease our development process and provide an overview of their advantages/limitations in our project. Finally, we evaluate the foreseen developments, including how this work can serve as the foundation for an exploration of AxC techniques in future low-power GNSS receivers.

Authors: Sun Hao , Cheng Yuehua , Jiang Bin , Lu Feng , Wang Na
Published: January 2024

The power system, as a core component of a launch vehicle, has a crucial impact on the reliability and safety of a rocket launch. Due to the limited measurement information inside the engine, it is often challenging to realize fast and accurate anomaly detection. For this reason, this paper introduces the rocket flight state data to expand the information source for anomaly detection. However, engine measurement and rocket flight state information have different data distribution characteristics. To find the optimal data fusion scheme for anomaly detection, a data set information fusion algorithm based on convex optimization is proposed, which solves the optimal fusion parameter using the convex quadratic programming problem and then adopts the adaptive CUSUM algorithm to realize the fast and accurate anomaly detection of engine faults. Numerical simulation tests show that the algorithm proposed in this paper has a higher detection accuracy and lower detection time than the traditional algorithm.

Gallium liquid metals (LMs) like Galinstan and eutectic Gallium-Indium (EGaIn) have seen increasing applications in heavy metal ion (HMI) sensing, because of their ability to amalgamate with HMIs like lead, their high hydrogen potential, and their stable electrochemical window. Furthermore, coating LM droplets with nanopowders of tungsten oxide (WO) has shown enhancement in HMI sensing owing to intense electrical fields at the nanopowder-liquid–metal interface. However, most LM HMI sensors are droplet based, which show limitations in scalability and the homogeneity of the surface. A scalable approach that can be extended to LM electrodes is therefore highly desirable. In this work, we present, for the first time, WO-Galinstan HMI sensors fabricated via photolithography of a negative cavity, Galinstan brushing inside the cavity, lift-off, and galvanic replacement (GR) in a tungsten salt solution. Successful GR of Galinstan was verified using optical microscopy, SEM, EDX, XPS, and surface roughness measurements of the Galinstan electrodes. The fabricated WO-Galinstan electrodes demonstrated enhanced sensitivity in comparison with electrodes structured from pure Galinstan and detected lead at concentrations down to 0.1 mmol·L−1. This work paves the way for a new class of HMI sensors using GR of WO-Galinstan electrodes, with applications in microfluidics and MEMS for a toxic-free environment.
Positively Charged Organosilanes Covalently Linked to the Silica Network as Modulating Tools for the Salinity Correction of pH Values Obtained with Colorimetric Sensor Arrays (CSAs)
Authors: Pastore Andrea , Badocco Denis , Cappellin Luca , Tubiana Mauro , Pastore Paolo
Published: January 2024

Seven increasing levels of water salinity from 0.029 to 0.600 M (as NaCl) were used to investigate the dependence of pH measurement, performed using colorimetric sensor arrays (CSAs), on ionic strength. The CSAs were arrays of sensing spots prepared in the form of sol–gel-embedding Bromothymol Blue (BB) and Bromocresol Green (BCG) in a porous nitrocellulose support. The support was impregnated over the entire thickness (≈100 µm), allowing for the signal (Hue) acquisition on the opposite side to the contact with the sample solution. Three CSAs were prepared, M1, M2, and M3. M1 contained a free cationic surfactant, hexadecyltrimethylammonium p-toluenesulfonate (CTApTs), for modulating the pKa of the indicators. In M2, the surfactant dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride (DTSACl) was covalently bonded to the sol–gel. M3 was prepared like M2 but using a larger amount of ethanol as the solvent for the synthesis. The modulation of the CTApTs or the DTSACl concentration enabled the tuning of the pKa. In general, the pKa modulation ability decreased with the increase in salinity. The presence of a surfactant covalently linked to the backbone partially reduced the competitiveness of the anionic species, improving the results. Nevertheless, the salt effect was still present, and a correction algorithm was required. Between pH 5.00 and 12.00, this correction could be made automatically by using spots taken as references to produce sensors independent of salinity. As the salt effect is virtually absent above 0.160 M, M2 and M3 can be used for future applications in seawater.
Modeling Structured Dependency Tree with Graph Convolutional Networks for Aspect-Level Sentiment Classification
Authors: Zhao Qin , Yang Fuli , An Dongdong , Lian Jie
Published: January 2024

Aspect-based sentiment analysis is a fine-grained task where the key goal is to predict sentiment polarities of one or more aspects in a given sentence. Currently, graph neural network models built upon dependency trees are widely employed for aspect-based sentiment analysis tasks. However, most existing models still contain a large amount of noisy nodes that cannot precisely capture the contextual relationships between specific aspects. Meanwhile, most studies do not consider the connections between nodes without direct dependency edges but play critical roles in determining the sentiment polarity of an aspect. To address the aforementioned limitations, we propose a Structured Dependency Tree-based Graph Convolutional Network (SDTGCN) model. Specifically, we explore construction of a structured syntactic dependency graph by incorporating positional information, sentiment commonsense knowledge, part-of-speech tags, syntactic dependency distances, etc., to assign arbitrary edge weights between nodes. This enhances the connections between aspect nodes and pivotal words while weakening irrelevant node links, enabling the model to sufficiently express sentiment dependencies between specific aspects and contextual information. We utilize part-of-speech tags and dependency distances to discover relationships between pivotal nodes without direct dependencies. Finally, we aggregate node information by fully considering their importance to obtain precise aspect representations. Experimental results on five publicly available datasets demonstrate the superiority of our proposed model over state-of-the-art approaches; furthermore, the accuracy and F1-score show a significant improvement on the majority of datasets, with increases of 0.74, 0.37, 0.65, and 0.79, 0.75, 1.17, respectively. This series of enhancements highlights the effective progress made by the STDGCN model in enhancing sentiment classification performance.
Active Compliance Smart Control Strategy of Hybrid Mechanism for Bonnet Polishing
Authors: Li Ze , Cheung Chi Fai , Lam Kin Man , Lun Daniel Pak Kong
Published: January 2024

Compliance control strategies have been utilised for the ultraprecision polishing process for many years. Most researchers execute active compliance control strategies by employing impedance control law on a robot development platform. However, these methods are limited by the load capacity, positioning accuracy, and repeatability of polishing mechanisms. Moreover, a sophisticated actuator mounted at the end of the end-effector of robots is difficult to maintain in the polishing scenario. In contrast, a hybrid mechanism for polishing that possesses the advantages of serial and parallel mechanisms can mitigate the above problems, especially when an active compliance control strategy is employed. In this research, a high-frequency-impedance robust force control strategy is proposed. It outputs a position adjustment value directly according to a contact pressure adjustment value. An open architecture control system with customised software is developed to respond to external interrupts during the polishing procedure, implementing the active compliance control strategy on a hybrid mechanism. Through this method, the hybrid mechanism can adapt to the external environment with a given contact pressure automatically instead of relying on estimating the environment stiffness. Experimental results show that the proposed strategy adapts the unknown freeform surface without overshooting and improves the surface quality. The average surface roughness value decreases from 0.057 um to 0.027 um.

Published: January 2024

To investigate the impact of underground water seepage and soil stress fields on the deformation of excavation and support structures, this study initially identified the key influencing factors on excavation deformation. Subsequently, through a finite element simulation analysis using Plaxis, this study explored the effects of critical factors, such as the excavation support form, groundwater lowering depth, permeability coefficient, excavation layer, and sequence on excavation deformation. Furthermore, a comprehensive consideration of various adverse factors was integrated to establish excavation support early warning thresholds, and optimal dewatering strategies. Finally, this study validated the simulation analysis through an on-site in situ testing with wireless sensors in the context of a physical construction site. The research results indicate that the internal support system within the excavation piles exhibited better stability compared to the external anchor support system, resulting in a 34.5% reduction in the overall deformation. Within the internal support system, the factors influencing the excavation deformation were ranked in the following order: water level (35.5%) > permeability coefficient (17.62%) > excavation layer (11.4%). High water levels, high permeability coefficients, and multi-layered soils were identified as the most unfavorable factors for excavation deformation. The maximum deformation under the coupled effect of these factors was established as the excavation support early warning threshold, and the optimal dewatering strategy involved lowering the water level at the excavation to 0.5 m below the excavation face. The on-site in situ monitoring data obtained through wireless sensors exhibited low discrepancies compared to the finite element simulation data, indicating the high precision of the finite element model for considering the fluid–structure interaction.

Switched filter banks find widespread application in frequency-hopping radar systems and communication networks with multiple operating frequencies, especially in situations demanding elevated filter element isolation. In this paper, the design and implementation of a highly isolated switchable narrow-bandpass filter bank architecture using hairpin microstrip topology is presented. The filter bank has four discrete bandpass filters with passbands of 2.0–2.2 GHz, 2.3–2.5 GHz, 3.1–3.3 GHz, and 3.9–4.1 GHz. These filters span the radar S-frequency band (2.0–4.0 GHz). In order to switch between channels with a switching speed of nanoseconds, low-loss and highly isolated SP4T switches are implemented. Advanced design system (ADS) software is used to design the various filter functionalities, and the entire system is tested on a vector network analyzer (VNA). The proposed architecture makes it much easier to put the filter bank into practice and switch it to the desired frequency, which is useful for radar receiver applications.

A ruptura do LCCr resulta em instabilidade e é conhecida como insuficiência ou doença do ligamento cruzado cranial (DLCCr), envolvendo alterações morfofuncionais associadas a essa estrutura anatômica. Uma técnica cirúrgica mais recente para a reconstrução do LCCr é a substituição do ligamento intracapsular por uma prótese ligamentar sintética, conhecida como Evolig® (prótese ligamentar de tereftalato de polietileno tipo 155), desenvolvida pelo Dr. J. P. Laboureau. Sendo assim, este trabalho irá relatar um caso de reconstrução do ligamento cruzado cranial utilizando a prótese ligamentar sintética Evolig® por meio de uma técnica intracapsular em um cão, sem raça definida de 32 kg com ruptura do LCCr direito, utilizando o ligamento de tamanho L2. Durante o acompanhamento pós-operatório de 90 dias, observou-se uma melhora significativa da estabilidade e função do joelho do animal, portanto a utilização da prótese Evolig® apresentou vantagens notáveis, como a possibilidade de carga compartilhada entre a prótese sintética e o tecido biológico, permitindo uma construção de ligamento cruzado cranial eficaz.

PERAN REGULASI DALAM MENGATUR PERDAGANGAN ONLINE DI INDONESIA: KEPATUHAN, PENYELESAIAN SENGKETA, DAN DAMPAKNYA PADA BISNIS ONLINE
Authors: Putra Dwi Savedo Yusuf Ardiyanto
Published: January 2024

Abstrak.

Peran regulasi dalam mengatur perdagangan online di Indonesia menjadi sangat penting. Regulasi, seperti Undang-Undang No. 19 Tahun 2016 tentang Perdagangan Elektronik (UU ITE), Undang-Undang Perlindungan Konsumen, dan peraturan lainnya, membentuk kerangka hukum yang mengawasi praktik bisnis online. Peraturan ini bertujuan untuk memastikan bahwa perdagangan online berlangsung secara adil, aman, dan terpercaya. Namun, masih ada sejumlah tantangan yang harus dihadapi dalam perdagangan online. Salah satunya adalah penyelesaian sengketa yang seringkali rumit, terutama dalam konteks sengketa lintas yurisdiksi. Selain itu, kepatuhan terhadap regulasi, seperti peraturan perpajakan dan perlindungan konsumen, menjadi isu penting. Beberapa pelaku bisnis online mungkin tidak mematuhi aturan ini. Simpulan dari penelitian ini adalah bahwa kepatuhan terhadap regulasi adalah kunci untuk menjaga integritas bisnis online, melindungi konsumen, dan mencegah risiko hukum. Selain itu, diperlukan mekanisme penyelesaian sengketa yang lebih efisien dan mekanisme Online Dispute Resolution (ODR) yang lebih kuat untuk mengatasi sengketa dalam perdagangan online. Rekomendasi yang dapat diambil adalah pembaruan dan penguatan regulasi yang responsif terhadap perubahan teknologi dan perilaku konsumen. Selain itu, pendekatan yang lebih aktif terhadap penegakan hukum dan pengawasan terhadap pelaku bisnis online perlu diterapkan. Dengan cara ini, kita dapat menciptakan lingkungan perdagangan online yang lebih adil, aman, dan terpercaya di Indonesia.

South Central Timor Regency, especially the South Coastal part, is an area with a dry climate which is an optimal area for the growth of the genus Ficus. Previous research data shows that on Timor Island there are 25 types of Ficus out of 252 species found in Indonesia. However, this data is not based on the results of field research, but from the results of reviews of other studies. Therefore, the purpose of this study was to identify the types of plants of the Ficus genus found on the South Coast of South Central Timor and determine the level of species diversity. The method used in this study is the exploratory method by exploring each coastal habitat, rivers, rocky hills or steep slopes, agricultural land, settlements and forests. To determine the type of Ficus, it was identified based on the criteria of Berg & Corner (2005) while the level of species diversity was determined based on the Shannon Wiener diversity index. The results showed that on the South Coast of Timor Tengah Selatan there were 956 individuals consisting of 19 species of Ficus and 3 of them namely Ficus callophylla, Ficus drupacea and Ficus microcarpa which had never been reported on the island of Timor. The level of species diversity is included in the moderate category, this is because only a few species dominate.
