Construction of Intelligent Practice System of Visual Arts Based on VR Technology in Information Age

Abstract Taking visual art intelligence as an entry point, this paper describes the transformation brought by the information age to the expression of visual art. Based on VR technology to build a practice system of visual art intelligence, VR positioning technology is used to locate the three-dimensional coordinates of the operator in order to realize the independent positioning of multiple operators in a large space and avoid positioning interference. Through the eye movement multi-channel interaction algorithm based on head-eye synergy, the two-dimensional interaction task in flow field visualization is completed, and then gesture interaction is added to complete the three-dimensional interaction task. The constructed system was implemented in the teaching of art majors at College Z, and the data were analyzed. The results show that the total average scores of innovative theoretical ideas, interactive experience feeling, symbolic integration of creative content and infinite extension of the multidimensional spatial field are 82.42, 83.57, 80.84 and 80.28, respectively. The data show that teachers, students and parents recognize the intelligent system of visual arts and believe that it improves students’ innovative ability in art creation, enhances the interactive experience feeling of visual arts, and provides data support for the continuous research and exploration of contemporary visual arts.

Mechanisms of forming the image of the Russian Federation in China

The article is about the consideration of the mechanisms for the formation of an objective Russian agenda in the People's Republic of China against the backdrop of a growing trend towards the transmission of a distorted image of Russia by the United States and its allies. China is the most important ally for Russia at the present stage, and, like Russia, it sees a similar structure of the world order and takes an independent and independent position on international issues. Non-alignment with Western sanctions against Russia, as well as active support, which is expressed in increasing strategic cooperation, joint projects, the creation of new agreements that strengthen and develop existing ties in many areas, speak of an unprecedented level of support for China. It is interesting to take a more detailed look at the political interaction between the two countries, namely, the fi eld of public diplomacy and the mechanisms and methods that are used by the parties to promote the image of a partner country in their own country. As noted by A. A. Velikaya, describing the principles on which Russian public diplomacy should be based, notes that special attention should be paid to those countries that already have a positive attitude towards Russia, and efforts to win the critical masses may be ineffective. Taking into account the mutual recognition by Russia and China of the wording "comprehensive partnership and strategic interaction in a new era" to describe bilateral relations, it speaks of the readiness and need for mutual promotion of a favorable image of countries to strengthen dialogue between peoples. Of interest are the advanced methods applied by the two countries to achieve this goal.

Taxonomic status of the Central Asian damselfly Calopteryx samarcandica Bartenev, 1912 (Odonata: Calopterygidae)

The taxonomic status of the Central Asian damselfly Calopteryx samarcandica was determined on the basis of molecular and phenotypic data from the Kugitang Mountains, SE Uzbekistan. Molecular analyses (COI and 18S rDNA, ITS1-5.8S rDNA-ITS2) revealed that C. samarcandica forms part of a clade that includes taxa treated in the literature as subspecies of Calopteryx splendens and/or related species. However, both mitochondrial and nuclear DNA confirmed that C. samarcandica deserves separate species status. The COI distance to C. splendens (including C. xanthostoma) is moderate (3.47%, K2P), but much greater than the internal distances between the sequences qualified in C. splendens (0.4%); this difference is supported by the low values of the barcoding gap in this genus. The rather distant separation of C. samarcandica from both C. splendens (ancilla, taurica, intermedia) and C. orientalis and the length of the samarcandica-branch recognisable in nuclear rDNA strengthen the independent position of the first species. The phylogenetic position of C. samarcandica in the genus Calopteryx remains unclear due to the low variability of nuclear rDNA markers and insufficient and partly incomparable data for other taxa. The molecular data support the phenotypic and ecological specificity of C. samarcandi­ca, defined by a diagnostic combination of its traits (male and female wing colours and large size and basal diffusion of the wing spot in males) and the conservative association with groundwater-fed natural watercourses in the mountains and foothills fringing the vast Central Asian mountain block.

Trans-Japan Sea land-bridge disjunction: A case of vicariance in the subterranean genus Nipponasellus (Crustacea, Isopoda, Asellidae) in a large-scale biogeographical context.

This study examines nineteen phreatobiological hand pump samples collected in 20092010 in three separate areas of salmon river basins in the southern part of Primorye, in the Far East of Russia. For the first time, faunal groundwater patterns were assessed for the rivers of Eastern Manchuria, the Ussury River Basin and the rivers of the south-western slope of Sikhote Alin. A total of 164 species (including 32 stygobionts) belonging to the phyla Annelida, Mollusca and Arthropoda are first records of groundwater animals, and two of the stygobionts are described below as new species for Science. Nipponasellus sudzukhensis spec. nov. and N. matsumotoi spec. nov. are described and illustrated, and their taxonomic affinities with congeners are discussed. The morphology of male pleopod 2 of the genus Nipponasellus is re-examined using scanning electron microscopy (SEM), which revealed fine details of the pleopodal structures. The two new continental species of Nipponasellus were characterised by a distinct cannula completely immersed in ctenoid cuticular scales and the absence of a labial spur. Informal macrogroups were proposed based on the structure of the appendix masculina and an analysis of family distribution. The results of cladistic analyses revealed relationships between the proposed groups, but phylogenetic relationships within the Caecidotea-Proasellus group remain challenging. Common diagnostic characters of Nipponasellus showed that the group occupies an independent position close to the Caecidotea-Proasellus group rather than the Asellus-pattern sensu Magniez. Revised diagnosis for the genus Nipponasellus is given, including the two new species and the five previously described ones. The species diversity of East Asian stygobiotic asellid isopods is briefly reviewed to infer a biogeographic distribution pattern that emphasises the strict endemicity of members of the genus Nipponasellus. The intracontinental separation between continental Far East Asia and the Japanese archipelago highlights the biogeographic importance of the land-bridge in the Oligocene and raises questions about hypotheses explaining the (disjunct) distribution in East Asia, together with the circumstances preceding an ancient colonisation of the region.

Gosplan and the problem of conversion in the Soviet military industry in the second half of the 1940s

There is an opinion about the exclusively technical functions of the State Planning Committee in historiography. However, this institution played a significant role in the development of economic policy strategies and its implementation. Using the example of the conversion of the military industry in 1945-1950. the role of the State Planning Committee is shown as an important element of the state system. He was not a conductor of the decisions of the Stalinist leadership, but took an independent position on carrying out the conversion and limited the “opportunism” of the military-industrial departments. The determining factor was the personality of N.I. Voznesensky. Throughout the 1940s. he was a member of the leadership of all senior structures involved in economic management. The influence of the State Planning Committee on political decision-making was directly related to the career growth and strengthening of the administrative weight of its leader.

Motion Control of Capsule Robot Based on Adaptive Magnetic Levitation Using Electromagnetic Coil

In view of the magnetically actuated capsule robot applications in diagnoses of human stomach disease, the challenges that are associated with degrees-of-freedom (DOF), environmental adaptability, and the size of the entire system must be addressed. In this study, a new electromagnetic coil system that is based on adaptive magnetic levitation is presented; it is mainly composed of an independent orientation control electromagnetic coil and a magnetic levitation control electromagnetic coil. The system is designed to perform motion control of the capsule, including 3-DOF levitating translational motion control, and pitch and yaw motion control in levitation. In this manner, it compensates for the lack of previous magnetic levitation systems that were based on electromagnetic coils for the control of the tilt angle of the capsule. With torque-based actuation control, the tilt angle of the capsule can be controlled continuously with an angle increment of no more than 2 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$^{\circ}$</tex-math> </inline-formula> (within 30 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$^{\circ}$</tex-math> </inline-formula> ) during levitation. The capsule under the magnetic levitation control, which is based on the fuzzy proportional-integral -derivative controller, can maintain the stability of levitation; the error between the actual capsule position and the required position did not exceed 0.1 mm when the capsule was out of water or completely immersed in it. Moreover, the experiment of the capsule levitating from air to water further verifies the adaptability of the system with regard to the environment; this provides a new examination method for capsule endoscopy. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Note to Practitioners</i> —This work is caused by the motion manipulation problem of a magnetically driven capsule robot. Most of the existing magnetically driven capsule robots use a rolling or sliding method that fits tightly against the stomach wall, and these forms of motion make it possible to risk missing diagnoses in the examination of gastric diseases, and the maneuverability limits its further application. This paper proposes an adaptive control strategy for a magnetically driven capsule robot based on magnetic levitation motion. It allows the magnetically driven capsule robot to levitate to any position in the stomach for photography and observation without external mechanical support, and this levitation motion is sufficiently stable. In addition, the proposed capsule robot has independent orientation and position control, which has the potential to achieve automated inspection.

Pathway to Independence Awards (K99/R00): Funding Dynamics and Prediction of Future National Institutes of Health Research Project Funding.

The authors used the National Institutes of Health (NIH) RePORTER (Research Portfolio Online Reporting Tools) to evaluate funding trends and historic NIH investment increase in the K99 award pathway and examine whether R00 to R01 or R21 achievement time correlated with the future success of an early-stage NIH-funded investigator. All K99 awards and funding data in this study were limited to all clinical departments. The authors identified all researchers and awards through a K99 search from fiscal years (FYs) 2007 to 2022 across all clinical departments and investigated trends in K99 awards and funding from NIH FYs 2007 to 2022. They generated an R00 data set and analyzed the K99 to R00 achievement statistics from FYs 2007 to 2022. The authors aggregated NIH annual data files for FYs 2007 to 2021 to generate a master data file of all R01 and R21 awards. They linked R01 and R21 award data to the researcher previously identified through the K99 search and focused on the connection between K99/R00 awardees and subsequent R01 or R21 awards. From FY 2008 to FY 2022, the NIH K99 budget increased 127.0%, whereas the NIH program-level budget increased 17.3%. A principal investigator's mean funding per year significantly decreased as time from R00 to R01 or R21 increased ( P < .001); 7 of 15 comparisons differed significantly (2 at P < .01 and 5 at P < .001). NIH investment in the K99 award pathway has substantially outpaced the NIH program-level budget increase, and there is a strong association between mean funding per year since the start of the R00 phase and time from R00 to R01 or R21. This analysis may be useful to clinical departments as they evaluate selecting new and retaining current biomedical scientists for independent research positions.

The application of extended kalman filtering based on SLAM

EKF (Extended Kalman Filter) is a non-linear state estimation algorithm based on the development of Kalman filtering technology. In SLAM (Simultaneous Localization and Mapping), EKF technology is widely used to realize robots' independent positioning and map construction. EKF technology mainly estimates the state of the robot by using the information provided by the sensor, and then realizes the robot's self-positioning and the environment's map. This paper uses EKF algorithm for testing, and analyses the simulation results, which compared with Kalman filtering technology, the main difference between the two is that EKF can handle non -linear dynamic systems. In SLAM, robots often detect environmental detection through sensors such as laser radar, camera, and then update the position and posture of the robot by the receiving sensor data. In this process, the EKF technology can perform non -linearity by sensor data by sensor data Transformation makes the state of the robot more accurately estimate. Specifically, Extended Kalman Filtering technology can be divided into two steps: prediction and update. In the predicted phase, EKF uses the current robotic status and motion equation to predict the robot status of the next moment; in the update stage, EKF uses sensors to measure data to update the current state of the robot. By repeating the prediction and updating two steps, you can get the trajectory of the robot movement and the map of the environment where the robot is located.

Combining Magnetic and Gyroscopic Surveys Provides the Best Possible Accuracy

Summary A survey program is designed for every well drilled to meet the well objective of penetrating the target reservoir and avoiding a collision with nearby offset wells. The selection of the wellbore survey tools within the survey program is limited in number and accuracy by the current surveying technologies available in the industry. This article demonstrates how a higher level of accuracy can be achieved to meet challenging well objectives when the accuracy of the most accurate wellbore surveying tools and technologies taken individually is insufficient. This high level of wellbore positioning accuracy is achieved by combining two independent wellbore positions of the same wellbore trajectory. The first wellbore position is calculated using the latest technology of magnetic measurement-while-drilling (MWD) definitive dynamic surveys (DDS). The accuracy of the MWD DDS can be further improved by minimizing error sources such as misalignment of the survey package from the borehole, drillstring magnetic interference, the use of localized geomagnetic reference, using high-accuracy accelerometer sensors, and a high-accuracy gravity reference. Furthermore, the MWD DDS inclination accuracy is improved using an independent inclination measurement from the rotary steerable system. A first wellbore position is calculated from the magnetic MWD DDS after applying in-field referencing (IFR), multistation analysis (MSA), bottomhole assembly (BHA), sag correction (SAG), and dual-inclination (DI) corrections to improve both azimuth and inclination accuracy. A second wellbore position is calculated using gyro-MWD (GWD) technology. The results and comparisons of multiple combined survey runs are presented. The highest accuracy of wellbore positioning had been proved in this successful case study by penetrating a very small reservoir target on an extended-reach well that was unfeasible using either the most accurate enhanced MWD DDS or GWD technology individually. The presented case study shows how the wellbore objectives of penetrating a very small reservoir target had been confirmed by logging-while-drilling images and the reservoir mapping interpretation of the client subsurface team. This gave a high-accuracy wellbore position during drilling and provided higher confidence in wellbore placement to maximize reservoir production without colliding with nearby offset wells. Wellbore survey accuracy limits a borehole’s lateral and true vertical depth (TVD) spacing, constraining reservoir production in those sections. In the top and intermediate sections, wellbore survey accuracy limits how close the wellbore can be drilled to other offset wells due to collision concerns. This directly impacts the complexity of the directional work and the cost per section. Combining independent wellbore surveys unlocks the potential to improve the wellbore positioning accuracy significantly. It demonstrates the highest wellbore positioning accuracy that can be achieved to date compared with the latest magnetic MWD surveys after correcting all known errors or compared with GWD.

Parametric Observer Controlled Motor Invariant Electronic Commutation of Photovoltaic Powered BLDCM Without Position Sensor

The development of parameter independent position sensor free control of permanent magnet brushless DC (PMBLDC) motor is one of the most challenging tasks. A motor parameter independent parametric observer based electronic commutation control is developed here without using rotor position sensor. The effect of motor parameter variation along with the change of motor, on electronic commutation control without using the rotor position sensor is considered as the disruption parameter for the developed control algorithm to mitigate the external disruption. Mitigation of control loop disturbances is done using the parametric observer based feedback control. A hybrid maximum power extraction algorithm using traverse and incremental conductance is implemented here for effective solar maximum power extraction. The implemented parametric observer motor invariant (POMI) based position sensor free control algorithm is verified using experimental process. Performance of the implemented POMI control is observed better in performance in comparison with the conventional position sensor free control as parametric variation is not considered in conventional control. The solution proves to be the best fit for any type of BLDC motor based water pumping solution irrespective of the pump configuration.

Adaptive Robust Time-Varying Formation Control of Quadrotors under Switching Topologies: Theory and Experiment

This paper investigates a practical time-varying formation control method for quadrotors subjected to disturbances, uncertainties, and switching-directed topologies. A fully distributed formation control scheme is proposed using a linear-velocity independent position controller (LVIPC) and a nonsingular terminal sliding mode attitude controller (NTSMAC). A distributed observer is adopted to eliminate the measurement of linear-velocity states, and only local neighbor states are needed to realize formation flight. A time-varying nonsingular terminal sliding mode manifold is designed to suppress the reaching phase and ensure the finite-time convergence. Adaptive estimators are employed to remove the reliance on the prior knowledge of the upper bound of lumped uncertainties. It is then proven that all the closed-loop signals are bounded under the proposed method. Comparative experimental results based on a practical outdoor hardware solution are presented to confirm the effectiveness of the suggested control algorithm.

RETRACTED ARTICLE: Intelligent monitoring methodology for large-scale logistics transport vehicles based on parallel Internet of Vehicles

The essence of the Internet of Vehicles is a social and physical information system, including the psychological and organizational factors of human beings. The complexity of the Internet will lead to certain deviations when monitoring vehicles. Therefore, the Parallel Internet of Vehicles is employed to monitor the information on large-scale logistics transport vehicles. This platform is built based on the ACP intelligent approach, which consists of three parts: An artificial system (A), a computational experiment (C), and parallel execution (P). The Adaboost algorithm is used to extract information on large-scale logistics transport vehicles from the ACP parallel Internet of Vehicles, and the Tabu search strategy is applied to optimize the Monte Carlo positioning algorithm. The approximate optimal estimation is obtained by optimizing the filtering to eliminate vehicle positions with fewer possibilities. The weight of important sampling values of the independent vehicle node positions is integrated to complete the posterior probability distribution estimation of the possible positions of vehicles, in order to realize vehicle position monitoring. It is verified that the root-mean square error of the algorithm when positioning a vehicle is less than 0.18, and the monitoring deviation is quite small.

Atomic distributions of Ag and In in the γ-brass type Ag9In4

The γ-brass type phase Ag9In4 in the binary Ag–In system has been synthesized by high-temperature method and, the crystal structure has been determined by the means of X-ray diffraction techniques and energy dispersive X-ray spectroscopy. The structure crystallizes in the primitive cubic space group P4‾3m (cP52) with a cell parameter of ∼ 9.89 Å. The unit cell contains 52 atoms distributed over 8 crystallographically independent positions. Due to weak X-ray scattering contrast between Ag and In, first principle DFT calculations have been carried out to determine the accurate site occupancy pattern of Ag and In in the structure of Ag9In4. The structure can be viewed in terms of two symmetrically inequivalent 26-atom γ-clusters (Ag22In4 and Ag14In12). The density of state (DOS) curve shows a pseudogap near the Fermi level, which endorses the phase stability by Hume-Rothery mechanism due to interaction between the Fermi surface and the Brillouin zone (FS-BZ). Bonding analysis shows that Ag–In contact has the highest contribution in stabilizing the titled phase.

INDEPENDENT DIRECTORS: A COMPARATIVE STUDY OF INDIA AND SINGAPORE

Any economy's ability to grow and develop sustainably depends heavily on the corporate sector. Comparatively speaking, jurisdictions with stronger governance are more prosperous than those with weaker corporate governance. Although the concept of an independent director was first introduced in the United States of America as a voluntary measure, it was made mandatory due to issues with management and shareholder agency theory, commonly known as the outsider's model issues. Regardless of the form of corporate governance they were using, the massive business failures that were taking place in different jurisdictions forced regulators all over the world to enact mandatory provisions addressing the Independent Directors. Several other countries adopted the concept to reorganize and rebuild the board structure in order to provide enhanced governance through the nomination of independent directors after the US and UK pioneered in this direction. The current paper's main objective is to examine the legal guidelines governing the independent director positions in Singapore and India, two Asian Pacific countries.

Visions of the Islamic State

Proponents of reform in Islamic political thought and practice frequently describe the work of Fazlur Rahman, the twentieth-century modernist scholar of Islam, and his method of Qur’ānic interpretation as a source of intellectual and political rejuvenation for contemporary Muslims. This article describes the ethicist underpinnings and content of Fazlur Rahman’s democratic vision of the Islamic state, as expressed in his major writings of the 1960s, and contrasts that vision with other proposals for establishing an Islamic nomocracy in contemporary Pakistan. The context of state building fundamentally shaped Fazlur Rahman’s constitutional theory, and his arguments expressly repudiate the traditional, independent position of the religious elites or ‘ulamā’ and aim at absorbing them into the state apparatus. This article contributes to the literature by explicating in a systematic way Fazlur Rahman’s constitutional theory, clearly drawing the connection between the ethicist content of his double-movement hermeneutic with the statism of his vision of Islamic democracy. Fazlur Rahman’s theory fails to establish a framework for an Islamic nomocracy, posing a significant challenge for advocates of intellectual and constitutional reform who champion the ethicist approach.

Konseptualisasi Klinik Penegakan Hukum Pemilu dalam Penanganan Pelanggaran Pemilu Tahun 2024

The election law enforcement clinic was introduced as an innovative endeavor to strengthen the mechanism for addressing violations in the upcoming 2024 elections. This idea emerged in response to the need for a more accountable, transparent, and violation-free election process that preserves its integrity and democratic credibility. The research conducted is a normative study that employs a legislative and conceptual approach. This study is grounded in theories of authority, concept formation, and the reality theory posited by Pierre Bourdieu. Through these theoretical lenses, the research delves deeply into the discourse on the establishment of the election law enforcement clinic. The findings indicate several crucial points. First, the authority to establish an election law enforcement clinic in Law Number 7 of 2017 is not explicitly stated. However, its regulation, which is implicit in nature, is facultative. This means that such a regulation is not binding or mandatory for implementation. Secondly, the design for the election law enforcement clinic can be developed using specific methods. Characteristics of this design include an ad hoc institutional structure, an independent position outside of Bawaslu, personnel comprising of election overseers and academics, and the utilization of a cooperation agreement as a legal instrument. Furthermore, funding for the clinic's operations can come from both Bawaslu and higher education institutions.

Detection and description of Ditylenchus israelensis n. sp. (Nematoda: Anguinidae) from bulbs of the Persian buttercup (Ranunculus asiaticus L.)

Summary The present study describes a new Ditylenchus species, isolated from the bulbs of the Persian buttercup (Ranunculus asiaticus L.) imported from Israel at the Ningbo plant quarantine lab, Ningbo, P.R. China. Ditylenchus israelensis n. sp. is an amphimictic species; females have six incisures in the lateral field, a long and slim body, a delicate, short stylet (7-8 μm) with small and rounded knobs, excretory pore in the anterior region of the basal pharyngeal bulb, posteriorly located vulva (V = 78.6-83.1), a short PUS (15.0-24.0 μm), and a long conical tail with a pointed terminus. Males are similar to females in general morphology and have 14.0-18.0 μm long spicules. The new species was also characterised molecularly using 18S, ITS and D2-D3 expansion segments of 28S rDNA genes. Our phylogenetic analyses showed its independent position among available Ditylenchus species and a close phylogenetic affinity with D. valveus. Several Ditylenchus species are regulated pests; their detection in a given sample can implement quarantine measures. However, to our knowledge D. israelensis n. sp. did not cause any damage to the R. asiaticus bulbs. In addition, future studies regarding fecundity and host association may shed some light on the pathogenic potential of D. israelensis n. sp.
