Application of Compensation Algorithms to Control the Speed and Course of a Four-Wheeled Mobile Robot

This article presents a tuned control algorithm for the speed and course of a four-wheeled automobile-type robot as a single nonlinear object, developed by the analytical approach of compensation for the object’s dynamics and additive effects. The method is based on assessment of external effects and as a result new, advanced feedback features may appear in the control system. This approach ensures automatic movement of the object with accuracy up to a given reference filter, which is important for stable and accurate control under various conditions. In the process of the synthesis control algorithm, an inverse mathematical model of the robot was built, and reference filters were developed for a closed-loop control system through external effect channels, providing the possibility of physical implementation of the control algorithm and compensation of external effects through feedback. This combined approach allows us to take into account various effects on the robot and ensure its stable control. The developed algorithm provides control of the robot both when moving forward and backward, which expands the capabilities of maneuvering and planning motion trajectories and is especially important for robots working in confined spaces or requiring precise movement into various directions. The efficiency of the algorithm is demonstrated using a computer simulation of a closed-loop control system under various external effects. It is planned to further develop a digital algorithm for implementation on an onboard microcontroller, in order to use the new algorithm in the overall motion control system of a four-wheeled mobile robot.

Effects of carrier structure parameters on diesel particulate filter capture performance based on grey relational analysis

To reduce the pressure drop of diesel particulate filter (DPF) as well as improve its collection efficiency. A mathematical model of DPF pressure drop and capture efficiency was established. This research systematically investigates the effects of channels per square inch (CPSI), wall thickness, and carrier ratio on DPF performance through grey relational analysis (GRA) and polynomial approximation algorithm (PAA). The findings reveal that DPF exhibits lower pressure drop and higher collection efficiency in the case where the carrier ratio, wall thickness, and CPSI are within the ranges of 1.40 to 1.53, 9.8 to 10.5 mil, and 200 to 300, respectively. Particularly, at a carrier ratio of 1.52 and a wall thickness of 10.38 mil, the pressure drop reaches a minimum value of 4.23 kPa, with a collection efficiency of 90.28%. Meanwhile, at a carrier ratio of 1.52 and a CPSI of 200, the pressure drop reaches a minimum value of 4.17 kPa, with a collection efficiency of 90.21%. The model expressions for pressure drop and collection efficiency derived from the PAA are: y 1 = 51.19 + 3.815 x 1 − 8.726 x 2 + 3.794 x 1 2 − 1.735 x 1 x 2 + 0.524 x 2 2 , and y 2 = 0.383 + 0.105 x 1 + 0.085 x 2 + 0.032 x 1 2 − 0.016 x 1 x 2 − 0.0032 x 2 2 . The foregoing models exhibit excellent predictive accuracy and goodness of fit for the DPF performance. Under the interactive influence of carrier ratio and wall thickness, the root mean square errors (RMSE) for pressure drop and collection efficiency are 0.0110 and 0.0002, respectively, with corresponding goodness of fit values of 0.9996 and 0.9985. As revealed by the GRA results, wall thickness exerts the most significant impact on DPF performance, presenting a GRG of 0.84 for filtration efficiency and 0.79 for pressure drop. The overall influence on both collection efficiency and pressure drop follows the descending order: wall thickness > carrier ratio > CPSI. This work has important engineering significance for optimizing the DPF capture performance and extending its working time.

Analytical Evaluation of MOSFET Secondary Effects

Abstract. MOSFET is a field effect transistor that can be used in a wide range of analog and digital circuits. It has the advantages of low power consumption, high speed and high integration. Its abbreviation is MOS. During the operation of MOS tubes, there are some secondary effects that cannot be ignored in circuit analysis and there is a research gap in analyzing and evaluating these effects. Therefore, in this paper, we will analyze and evaluate the body effect, channel length modulation effect, subthreshold conductivity effect, and short channel effect among the secondary effects by reviewing the related literature and give some methods to minimize the impact of secondary effects on circuits. In this study, the secondary effects of MOS tubes are discussed in depth. In the combing of previous related studies, the above several common secondary effects of MOS tubes are summarized and inductively analyzed, and the effects of reduced body effect and channel length modulation effect on circuits are summarized and evaluated. These results provide important theoretical support and practical guidance for MOSFET research.

Optimizing Circular MIMO Array Imaging Using Partial Equivalent Method for Sidelobe Suppression

In this paper, we propose a novel approach for circular Multiple-Input Multiple-Output (MIMO) array imaging, termed the Partial Equivalent Method (PEM), aimed at sidelobe suppression. In our method, the imaging process of the circular MIMO array is initially decomposed into bistatic circular synthetic aperture radar (BCSAR) components with different bistatic angles. Components with larger bistatic angles produce equivalent channels whose wavenumber spectra are concentrated near zero frequency, leading to significant broadening of the main lobe in the corresponding point spread function (PSF). In traditional MIMO imaging, each transmit–receive antenna pair is considered an equivalent channel, and all these channels are utilized for imaging. However, components with large bistatic angles, when integrated into the MIMO imaging output, result in increased sidelobe levels. To address this issue, we employ the PEM to restrict the range of equivalent channels. This method selectively retains effective channels generated by components with specific bistatic angles, effectively mitigating the adverse effects of BCSAR components with larger bistatic angles. Through point target simulations, electromagnetic simulations, and practical experiments, we demonstrate that the PEM significantly reduces sidelobes and enhances image quality in circular MIMO array imaging.

Energy-efficient design and CNFET implementation of GDI-based ternary prefix adders

Abstract Ternary adders have produced more benefits compared to binary adders i.e., the ternary adder occupies less amount of area as well as produces less interconnect complexity. However, the CMOS implementation of the ternary adders failed to perform the process when the channel length was taken as 32 nm. At 32 nm technology, the CMOS transistors exhibit undesired effects such as Short Channel Effects (SCEs), mobility degradation, high leakage current, etc. Multi-gate devices are preferred to overcome these issues. Carbon Nano-tube Field Effect Transistors (CNFETs) are one of the technologies to work efficiently when the channel length is 32 nm. In this paper, CNFET-based ternary prefix adders are designed. Power consumption is the most critical requirement for the VLSI system, as it enhances energy efficiency and reduces heat dissipation. One way to achieve this power reduction is by minimizing the number of transistors employed in the adder circuits. This study employed a reduction technique known as Gate Diffusion Input (GDI) logic included in the proposed prefix adder design. The overall experimental investigation is done with the help of the HSPICE supporting platform. The proposed adder improved by reducing the power by up to 83%, energy by up to 83%, current by up to 78%, and delay by up to 96%. Finally, the Power Delay product (PDP) was also reduced by 84% compared to existing ternary adders. The proposed design proves to be highly effective in implementing the neuron structure, with the corresponding parameters thoroughly analysed and well-documented in this study.

Device to circuit level implementation of JL-NSFET for DC/analog/RF applications at sub-5nm technology node: design optimization and temperature analysis

Abstract This manuscript introduces, for the first time, a novel approach that incorporates a comprehensive analysis of sheet variations (1–5) and every individual sheet wise temperature variation, and as well as an investigation of various GS high-k gate dielectrics in Junction-less (JL) Nanosheet FET (JL-NSFET). The study starting from device level (Digital/Analog/Radio Frequency) to circuit (CMOS Inverter and ring oscillator) as a whole package is investigated through well calibrated TCAD simulation and the results portrayed. NSFETs are the ultimate choice for integrated circuits (ICs) at sub-5 nm technology node. The notion of this paper is to design and optimization of NSFET with GS high-k gate dielectrics (Al2O3, HfO2, ZrO2 and TiO2) Initially. The switching/analog and RF metric revels that HfO2 is superior in terms SS, switching applications and more compactable with CMOS process. Further, adding number of sheets and temperature variation has been done later. As number of sheets increases, the effective channel width increases, electric field distribution takes place evenly and enhanced gate control owing to improved I O N , I O N / I O F F r a t i o , SS and DIBL. However, increasing the number of vertical channel layers (sheets) more than 2 results into diminished analog/RF performance of JL-NSFET owing to increased parasitic capacitances. Further, the impact of temperature variations (250 K to 450 K) studied for different sheet variations (1 to 5) and noticed that analog/RF such as gm, gds, fT, TFP and GTFP are enhanced by 40.82%, 28.76%, 40.69%, 64.62% and 70.59%, respectively at lower temperature (250 K) when compared to high temperature (450 K). These enhancements make the device is ideal for applications in cryogenic computing systems, satellites, deep space probes, and other aerospace technologies. Furthermore, as the circuit level implementation CMOS inverter and 5-stage ring oscillator (RO) are examined for different sheets and observed as sheets increase delay and EDP increases. For a CMOS inverter the NMH (0.295 V) and NML (0.280 V) are better at 2 sheets with a highest gain of 9.38 V/V. Hence, it is advised to use two or three sheets-based JL-NSFETs for high-performance and lower-power analog/RF applications.

Exploring characteristic features for effective HCN1 channel inhibition using integrated analytical approaches: 3D QSAR, molecular docking, homology modelling, ADME and molecular dynamics.

Neuropathic pain (NP) is characterized by hyperalgesia, allodynia, and spontaneous pain. Hyperpolarization-activated cyclic nucleotide-gated (HCN) channel involved in neuronal hyperexcitability, has emerged as an important target for the drug development of NP. HCN channels exist in four different isoforms, where HCN1 is majorly expressed in dorsal root ganglion having an imperative role in NP pathophysiology. A specific HCN1 channel inhibitor will hold the better potential to treat NP without disturbing the physiological roles of other HCN isoforms. The main objective is to identify and analyze the chemical properties of scaffolds with higher HCN1 channel specificity. The 3D-QSAR studies highlight the hydrophobic & hydrogen bond donor groups enhance specificity towards the HCN1 channel. Further, the molecular interaction of the scaffolds with the HCN1 pore was studied by generating an open-pore model of the HCN1 channel using homology modelling and then docking the molecules with it. In addition, the important residues involved in the interaction between HCN1 pore and scaffolds were also identified. Moreover, ADME predictions revealed that compounds had good oral bioavailability and solubility characteristics. Subsequently, molecular dynamics simulation studies revealed the better stability of the lead molecules A7 and A9 during interactions and ascertained them as potential drug candidates. Cumulative studies provided the important structural features for enhancing HCN1 channel-specific inhibition, paving the way to design and develop novel specific HCN1 channel inhibitors.

Computational Analysis of Interactions Between Drugs and Human Serum Albumin.

Drug molecules exist as complexed with serum proteins such as human serum albumin (HSA) and/or unbound free form in the blood circulation. Drugs can be effective only when they are free. Thus, it is important to understand aspects that are important for interaction between drugs and interacting proteins. In this study, interactions among 2990 FDA approved drugs and HSA were computational analyzed to unravel principles that are critical for drug-HSA interactions. Docking results showed that drugs have higher affinity toward cavity-1 (C1) than cavity-2 (C2). A total of 1131 drug molecules have docking score greater than 60 while 768 molecules have docking score greater than 60 when they are docked in C2. In addition, three solvent channels have potential to direct solvent to C1 cavity while C2 does not have any effective channel. The post MD analyses demonstrated that drugs are making polar interactions with basic amino acids in the binding cavities. Verbscoside and ceftazidime both have stable low RMSD values throughout MD simulation with 2 Å on average in C1 cavity. The ligand RMSD shows less stability for verbscoside, which is around 4 Å when it is in complex with HSA in C1. The individual contribution of the residues K192, K196, R215, and R254 to ceftazidime are -1.92 ± 0.18, -3.09 ± 0.09, -2.17 ± 0.17, and - 2.32 ± 0.098, respectively. These residues contribute the binding energy of the verbscoside by -6.06 ± 0.08, -2.10 ± 0.06, and - 1.57 ± 0.03 kcal/mol individually in C1 cavity. C2 is making polar interactions with drug via R469, K472, and K488 residues and their contribution to the two drugs are -3.13 ± 0.21 kcal/mol for R469, -1.94 ± 0.18 kcal/mol for K472, and -1.96 ± 0.11 kcal/mol for K488 to total binding energy of ceftazidime. The binding energy of verbscoside is 57.17 ± 7.00 kcal/mol and Arg-407 has the highest contribution this bind energy individually with -4.29 ± 0.12 kcal/mol. Drugs with hydrogen bond donor/acceptor chemical adducts such as verbscoside involve higher hydrogen bond formation in C1 pocket. Ceftazidime makes interaction with HSA toward hydrophobic residues, L384, L404, L487, and L488 in the C2 cavity.

Research on the influence of Spillover effect on dual-channel supply chain under the background of live-streaming marketing

In the context of live streaming marketing, it is crucial for members of the supply chain to allocate resources not only to enhance product quality through quality improvement efforts but also towards marketing initiatives aimed at boosting sales. This paper focuses on a dual-channel supply chain comprising a brand vendor and a streamer and investigates the spillover effect of the live streaming channel on traditional channels and product goodwill. By analyzing the Stackelberg game and differential game, this study compares the optimal equilibrium strategy and equilibrium profit under two decentralized models: the brand vendor-dominated decentralized model and the streamer-dominated decentralized model, as well as the centralized decision-making model. Additionally, this paper presents the optimal strategy and profit function of the product goodwill trajectory for the brand vendor, streamer, and the entire supply chain, considering different spillover effects using numerical simulation. The analysis reveals that the level of quality improvement consistently increases over time, while the variation in product goodwill is more diverse. The optimal pricing of products is influenced by the market share of the channel with goods under the decision of the two decentralized models. Risk-averse brands tend to collaborate with waist and tail streamers to gain control over bargaining power, while risk-seeking brands often choose top streamers to distribute their goods when the market share of goods channels is significant. The overall profitability of the supply chain is influenced by consumers’ preferences for quality and marketing.

Overcoming volumetric capacitance-rate performance tradeoff with 0D/2D conductive carbon nitride/phosphorene heterostructure for flexible supercapacitor

Few-layer black phosphorus (FL-BP) is considered a rising star 2D material for flexible supercapacitors (FSCs) due to its exceptional properties, including mechanical flexibility and high active surface area. However, the disordered deposition of FL-BP nanoflakes often leads to face-to-face restacking, which diminishes the effective active area and ion transport channels. This poses a huge challenge in simultaneously achieving high volumetric capacitance and rate capability. To address this, a 3D porous 0D/2D FL-BP/conductive carbon nitride (FL-BP/c-CN) film has been developed. The introduction of 0D c-CN nanoparticles effectively prevents the restacking of FL-BP nanoflakes and expands the nanofluidic channels, thus facilitating charge transport and ions diffusion. Additionally, the highly conductive c-CN nanoparticles embedded into the FL-BP layers significantly improve overall conductivity. As a result, the FL-BP/c-CN film-based FSC demonstrates a remarkable rate performance, retaining 70% capacitance as the scan rate increases from 10 to 100 mV/s. Moreover, the incorporation of 0D c-CN nanoparticles increases the available space for charge accumulation, yielding a volumetric capacitance of 28.5 F/cm3 at a scan rate of 10 mV/s, which is three times higher than that of a pure FL-BP film electrode (9.2 F/cm3). This work presents an innovative approach for developing high-performance FL-BP-based FSCs.

Synergistic potentiation between P3HT and PTAA enables blade-coated carbon-electrode perovskite solar cells with >21% outdoor and >35% indoor efficiencies

P3HT is a promising hole-transport layer (HTL) for efficient and stable carbon electrode-based perovskite solar cells (C-PSCs). However, the reported low efficiencies of P3HT C-PSCs, resulting from the unmatched band alignment and electronically poor contact between perovskite and P3HT, is an obstacle. In this work, we propose a binary HTL system that incorporates PTAA into P3HT to address this issue, thereby achieving efficiencies of 21.3 % (0.04 cm2) and 18.8 % (1.0 cm2) under AM 1.5G illumination, and 35.2 % under indoor illumination of 1000 lx, all of which are the highest reported values for low-temperature printable C-PSCs. Experimental and theoretical results revealed that the performance improvements mainly stem from the following collaborative effects between P3HT and PTAA: 1) the introduction of PTAA increases more face-on orientations of P3HT as well as enhanced π–π stacking, forming more effective charge transport channels as molecular bridges; 2) the hole extraction barrier from perovskite to P3HT is reduced by 0.07 eV through incorporating PTAA; 3) triarylamine PTAA and other more face-on configurations can provide additional and stronger passivation sites, intensifying the defect passivation effects. Finally, unencapsulated P3HT-PTAA C-PSCs maintain ≈91 % of initial performance after maximum power point tracking for over 900 h.

Engineering peroxisomal surface display for enhanced biosynthesis in the emerging yeast Kluyveromyces marxianus

The non-conventional yeast Kluyveromyces marxianus is a promising microbial host for industrial biomanufacturing. With the recent development of Cas9-based genome editing systems and other novel synthetic biology tools for K. marxianus, engineering of this yeast has become far more accessible. Enzyme colocalization is a proven approach to increase pathway flux and the synthesis of non-native products. Here, we engineer K. marxianus to enable peroxisomal surface display, an enzyme colocalization technique for displaying enzymes on the peroxisome membrane via an anchoring motif from the peroxin Pex15. The native KmPex15 anchoring motif was identified and fused to GFP, resulting in successful localization to the surface of the peroxisomes. To demonstrate the advantages for pathway localization, the Pseudomonas savastanoi IaaM and IaaH enzymes were co-displayed on the peroxisome surface; this increased production of indole-acetic acid 7.9-fold via substrate channeling effects. We then redirected pathway flux by displaying the violacein pathway enzymes VioE and VioD from Chromobacterium violaceum, increasing selectivity of proviolacein to prodeoxyviolacein by 2.5-fold. Finally, we improved direct access to peroxisomal acetyl-CoA and increased titers of the polyketide triacetic acid lactone (TAL) by 2-fold through concurrent display of the proteins Cat2, Acc1, and the type III PKS 2-pyrone synthase from Gerbera hybrida relative to the same three enzymes diffusing in the cytosol. We further improved TAL production by up to 2.1-fold through engineering peroxisome morphology and lifespan. Our findings demonstrate that peroxisomal surface display is an efficient enzyme colocalization strategy in K. marxianus and applicable for improving production of a wide range of non-native products.

Comprehensive Study of Low-Power SRAM Design Topologies

: The need for low power in portable and smart devices is the demand to be fulfilled for sustaining the semiconductor industry. Static Random Access Memory (SRAM) is the main part of the core design in chips. It is important to reduce the leakage power consumption during the steady mode of the device for the long run of the battery. This article is about the study of different modules using pre-existing low power. Application of different methods other than lowering the supply voltage leads to an increment in the number of transistors in conventional 6T (six transistor) SRAM cells like 7T to 14T. Power gating and the Multi-threshold complementary metal oxide semiconductor (MTCMOS) technique is the most relevant method. Hybrid low power techniques are in high demand because it shows better results than using individual techniques. However, the biggest challenge is to maintain the area and delay as well. FinFET came into the scenario to overcome the leakage power and short channel effect due to scaling in CMOS. Comparative study analysis shows that FinFET decreases the overall power and delay even when the number of transistors increases. A comparison was done between 6T, 8T, and 10T using FinFET and CMOS in a paper, and concluded that FinFET shows 77.792% improved write power.

An Examination of the Effects of 2M Channel Airing Turkish Soap Operas on Moroccan Audiences: 2009-2019

This paper attempts to shed light on the media effects of the 2M channel on Moroccan audiences viewing dubbed Turkish soap operas (TSO). In particular, the study limits its scope to 2009-2019 period of broadcasting. It is noted that the viewing process is a prerequisite for social change and media effects. This consideration of direct exposure hastens the effects and influences in the audiences’ lives. Not all media effects of TSO are detrimental to the Moroccan audience and government. No sooner had the audience finished a dubbed Turkish serial than the 2M started broadcasting a new one. Additionally, to examine this decade, the paper invests structured interviews and mail surveys to collect data. The study treats the research findings with content analysis and discourse analysis. Presumably, it is noticeable that females are the majority of viewers. Accordingly, the research findings are manifold. The study’s research findings seriously alert the media analysts and Moroccan cultural authorities concerned with Moroccan audiences susceptible to the TSO increasing dangers and insidious menaces. These foreign influences are disseminated through the ignorance, recipient, and Moroccan female lifestyles. Therefore, the result discussion necessitates an awakening paradigm shift in Moroccan cultural policy. In conclusion, the paper calls for an invigorating Moroccan public screen. Moroccan soap opera alternative likely replaces Turkish soap opera since Moroccan audience counts in millions alongside religious diplomacy as a form of soft power.

A user selection algorithm for downlink MU-MIMO systems using product of singular values of effective channels

User selection plays a crucial role when aiming to improve channel throughput in multiuser multiple- input multiple-output downlink systems with block diagonalization linear precoding. While an optimal group of users can be found by exhaustively searching all possible combinations of users, the process becomes prohibitively complex when there is a large number of users. In this paper, we propose a greedy suboptimal user selection algorithm, which iteratively selects a user to maximize the product of the singular values of the effective channels from a set of unselected users. The proposed algorithm is based on the iterative precoder design method, whereby interuser interference is perfectly cancelled with lower complexity than with the singular value decomposition-based precoding technique. Moreover, to avoid frequent use of singular value decomposition, the proposed algorithm applies QR decomposition to the selected channel matrices in order to obtain singular values, which are equivalent to the product of diagonal elements in the upper triangular matrix. Simulation results show that, under a high SNR regime, the proposed algorithm outperforms several other greedy algorithms and can provide the same performance as a capacity-based algorithm for both correlated and uncorrelated channels with significantly reduced complexity.

From sustainable development towards resilience: Does digital finance matter in enhancing ecological resilience?

AbstractDigital finance, as a representative of the digital economy, provides unprecedented opportunities for enhancing the adaptability and resilience of ecosystems. However, there is currently no literature that integrates digital finance and urban ecological resilience into the same research framework. In light of this, we utilize panel data from 2011 to 2019 to investigate the impact of digital finance on ecological resilience. Our results indicate that (1) Digital finance can effectively enhance ecological resilience, a conclusion corroborated by both theoretical frameworks and empirical evidence. Specifically, the coverage breadth and usage depth of digital finance can effectively enhance ecological resilience, while the digitization level has not shown a significant impact. (2) Green technological innovation, improvements in energy efficiency, and the agglomeration of producer services are identified as effective channels through which digital finance promotes ecological resilience. (3) The impact of digital finance on ecological resilience exhibits significant regional heterogeneity, with more pronounced effects observed in cities with advanced traditional financial systems, non‐resource‐based cities, and central cities. These findings will help policymakers better understand the relationship between digital finance and urban ecological resilience, and formulate targeted policies that leverage digital finance development to enhance ecological resilience.

This multifaceted approach underscores the dynamic and ever-evolving nature of FET technology, positioning it as a cornerstone for future advancements in electronics.

An In Vitro Study of 355‐nm Laser Ablation of Atherosclerotic Lesions Model

ABSTRACTA study of 355 nm laser with high pulse energy across various types of atherosclerotic lesion models is presented. The 355 nm laser pulses (10 ns) are delivered via a single fiber (600 μm diameter), and the ablation of calcified tissue, lipid tissue, and thrombus‐like tissue are studied under varied laser fluence (40–70 mJ/mm2) and repetition rate (5–30 Hz). The contact and noncontact ablation processes of chicken tibia samples (calcified tissue) are compared at 60 mJ/mm2 and 30 Hz, and the size of ablation particles is in the range of 0.1–1 μm. At the same repetition rate, the advancement rate of tricalcium phosphate samples reaches 150 μm/s at 70 mJ/mm2. Calcified and lipid models demonstrate predictable increases in ablation with higher laser fluence and repetition rate. The fresh porcine blood clot samples exhibit high‐quality ablation with good channel effect at 50 mJ/mm2 and 30 Hz.
