Timed Tissue P Systems With Channel States.

Tissue P systems with channel states are a variant of tissue P systems that can be employed as highly parallel computing devices, where the channel states can control the movements of objects. In a sense, the time-free approach can improve the robustness of P systems; hence, in this work, we introduce the time-free property into such P systems and explore their computational performances. Specifically, in a time-free manner, it is proved that this type of P systems have Turing universality by using two cells and four channel states with a maximum rule length of 2, or by using two cells and noncooperative symport rules with a maximum rule length of 1. Moreover, in terms of computational efficiency, it is proved that a uniform solution of the satisfiability ( SAT ) problem can be obtained in a time-free manner by applying noncooperative symport rules with a maximum rule length of 1. The research results of this paper show that a highly robust dynamic membrane computing system is constructed. Theoretically, relative to the existing system, our constructed system can enhance robustness and expand its application scope.

Dynamic Physics Educational Application for AR Environment

We propose a physics simulation application designed for Augmented Reality (AR), aiming to help high school students understand physical concepts such as mass, gravity, and friction. This application incorporates real-time object movement on a ramp, vector modulation based on forces, and physics calculations using user-specified parameters. Users can observe how objects respond to physical laws expressed by relevant formulas, enhancing comprehension of fundamental principles. Our research aims to enhance physics education by delivering an immersive learning experience through mobile devices. Through this approach, we also seek to make physics more accessible for students, fostering a grasp of challenging concepts.

Efficient Distortion-Free Neural Projector Deblurring in Dynamic Projection Mapping.

Dynamic Projection Mapping (DPM) necessitates geometric compensation of the projection image based on the position and orientation of moving objects. Additionally, the projector's shallow depth of field results in pronounced defocus blur even with minimal object movement. Achieving delay-free DPM with high image quality requires real-time implementation of geometric compensation and projector deblurring. To meet this demand, we propose a framework comprising two neural components: one for geometric compensation and another for projector deblurring. The former component warps the image by detecting the optical flow of each pixel in both the projection and captured images. The latter component performs real-time sharpening as needed. Ideally, our network's parameters should be trained on data acquired in an actual environment. However, training the network from scratch while executing DPM, which demands real-time image generation, is impractical. Therefore, the network must undergo pre-training. Unfortunately, there are no publicly available large real datasets for DPM due to the diverse image quality degradation patterns. To address this challenge, we propose a realistic synthetic data generation method that numerically models geometric distortion and defocus blur in real-world DPM. Through exhaustive experiments, we have confirmed that the model trained on the proposed dataset achieves projector deblurring in the presence of geometric distortions with a quality comparable to state-of-the-art methods.

Motion-Based Visual Encoding Can Improve Performance on Perceptual Tasks with Dynamic Time Series.

Dynamic data visualizations can convey large amounts of information over time, such as using motion to depict changes in data values for multiple entities. Such dynamic displays put a demand on our visual processing capacities, yet our perception of motion is limited. Several techniques have been shown to improve the processing of dynamic displays. Staging the animation to sequentially show steps in a transition and tracing object movement by displaying trajectory histories can improve processing by reducing the cognitive load. In this paper, We examine the effectiveness of staging and tracing in dynamic displays. We showed participants animated line charts depicting the movements of lines and asked them to identify the line with the highest mean and variance. We manipulated the animation to display the lines with or without staging, tracing and history, and compared the results to a static chart as a control. Results showed that tracing and staging are preferred by participants, and improve their performance in mean and variance tasks respectively. They also preferred display time 3 times shorter when staging is used. Also, encoding animation speed with mean and variance in congruent tasks is associated with higher accuracy. These findings help inform real-world best practices for building dynamic displays.

A Study of Visual Perception Based on Colour and Texture of Reconstituted Decorative Veneer

Color and texture, as vital physical attributes of recombinant decorative thin wood, represent the initial visual information perceived by the human eye. These elements play a crucial role in shaping the human viewing experience. This paper centers on the user’s visual perception of recombinant decorative thin wood and is divided into two main sections: the extraction and analysis of color and texture features, and experimental research evaluating combinations of color and texture. The experiments yielded conclusions indicating that the design of color and texture significantly influences objective eye movement data. Specific findings include: (1) The gaze duration, gaze counts, and hotspot maps of the subjects consistently demonstrate high agreement across the three eye movement indicators. Notably, a significant difference is observed between gaze indicators and color blending modes. (2) Asymmetric oblique blending and high-brightness circumferential blending tend to attract subjects’ eye attention more effectively. These color groups are characterized by transparent layers, increased brightness, and a pronounced visual impact. Such features enhance the design effect of the texture, highlighting its layers.

Modeling objects movement when collising with obstacles in PascalABC.NET language in schoolchildren's project activities

To solve the methodological problem of expanding the content of school informatics textbooks in terms of practical tasks, assignments for project work can be used, which are completed by students individually or in groups. Carrying out project work that involves the application of knowledge from other subject areas contributes to the development of meta-subject skills in students. The use of group work as the main form of performing practical tasks is aimed at achieving personal learning results. The project-activity approach helps to achieve the planned learning outcomes in the section of the informatics course under consideration. The article discusses assignments in the "Beginnings of programming" section of the VIII grade informatics course, which can be offered for students' project activities to create graphical and information models and when conducting a computer experiment. Based on the implementation of gradually more complex examples, students are introduced to project-type tasks — modeling the movement of objects when collising with obstacles. The software implementation of the models is carried out in the PascalABC.NET language.

ANALISIS BUKU GLOBALISASI (JALAN MENUJU KESEJAHTERAAN) DAN KAITANNYA DENGAN PEMBELAJARAN IPS

This writing aims to analyze the content of the book “Globalization: Road to Prosperity” and its relevance to social studies education, particularly in preparing social studies teachers to equip themselves as educators teaching social studies from a global perspective. The qualitative method is employed with a literacy study approach. Based on the analysis results, it can be concluded that the book “Globalization: Road to Prosperity” is more applicable to developed countries, while for developing countries, including Indonesia, it is more of a discourse, indicating that although we are in the era of globalization, entering it still requires a considerable amount of time. One notable agreement is that a statement in this book mentions, "Undeniably, we are now in communication, meaning that global communication is deceptive. When the internet is present in a country, it becomes more difficult to control what citizens do with it. However, modern technology is a double-edged sword, making it easier to regulate and monitor specific object movements. In education, facing the era of globalization, educators are responsible for developing and equipping learners with skills and confidence to face increasingly challenging life situations. Social studies educators can incorporate global education into social studies instruction to make learning more meaningful.

Phasal transfer and anti-locality: Movement of objects in Japanese

In this paper, based on an analysis of the scope properties of objects in Japanese, I argue that (i) an entire phase is transferred when a higher phase is completed, and (ii) the movement of objects and adjuncts is constrained by anti-locality. I propose that in the potential construction, the movement of accusative objects is more constrained than the movement of nominative objects owing to the interaction between phasal transfer and anti-locality, which leads the accusative and nominative objects to exhibit distinct scope behaviors. This analysis leads us to conclude that negation in Japanese is an adjunct. Furthermore, the analysis correctly predicts the movement of objects in simple transitive sentences and the non-movement of nominative phrases in certain cases.

Open-Source Instrumented Object to Study Dexterous Object Manipulation.

Humans use tactile feedback to perform skillful manipulation. When tactile sensory feedback is unavailable, for instance, if the fingers are anesthetized, dexterity is severely impaired. Imaging the deformation of the finger pad skin when in contact with a transparent plate provides information about the tactile feedback received by the central nervous system. Indeed, skin deformations are transduced into neural signals by the mechanoreceptors of the finger pad skin. Understanding how this feedback is used for active object manipulation would improve our understanding of human dexterity. In this paper, we present a new device for imaging the skin of the finger pad of one finger during manipulation performed with a precision grip. The device's mass (300 g) makes it easy to use during unconstrained dexterous manipulation. Using this device, we reproduced the experiment performed in Delhaye et al. (2021) We extracted the strains aligned with the object's movement, i.e., the vertical strains in the ulnar and radial parts of the fingerpad, to see how correlated they were with the grip force (GF) adaptation. Interestingly, parts of our results differed from those in Delhaye et al. (2021) due to weight and inertia differences between the devices, with average GF across participants differing significantly. Our results highlight a large variability in the behavior of the skin across participants, with generally low correlations between strain and GF adjustments, suggesting that skin deformations are not the primary driver of GF adaptation in this manipulation scenario.

“Holy to the Lord”: The Material Conversion of the Cammarata Finials

This article sets out to trace the trans-religious journey of two objects in the western Mediterranean at the end of the fifteenth century. The expulsion of Jews from all Spanish territories in 1492–1493 instigated the movement of objects from Jewish to Christian hands. Among these were a pair of Torah finials that belonged to the Jewish community of Cammarata, Sicily, where they were set on top of the rods around which the Torah scroll was rolled. These two finials were sold in Sicily and, through a chain of merchants and ecclesiastics, arrived at the Cathedral of Palma and were incorporated into the local Christian liturgy, a process that continued well into the twentieth century. This article analyzes the use and performance of the finials in their different liturgical settings and examines their conversion from Jewish ceremonial objects to ecclesiastical implements. It concludes with a discussion of temporality in studying converted objects, a factor that played a key role in the finials’ migration between socio-religious contexts and resulted in the creation of multifaceted objects.

CHALCOLITHIC/EARLY BRONZE AGE AND ADDITIONAL MAGDALENIAN RADIOCARBON DATES FOR EL MIRÓN CAVE (RAMALES DE LA VICTORIA, CANTABRIA, SPAIN). DATE LIST VII

ABSTRACTThere are now 101 radiocarbon dates from the long Paleolithic and post-Paleolithic culture-stratigraphic sequence in El Mirón Cave, Cantabrian Spain. Here we report on two dates on bone from two different humans whose remains were found in disturbed surface sediments in the cave vestibule rear and that confirm the existence of burials in addition to previously reported residential occupations in the vestibule front pertaining to the Chalcolithic and early Bronze Age periods (ca. 5500–3500 cal BP). In another attempt to resolve problems of stratigraphic incoherence of dates from the early Magdalenian periods in the vestibule rear, six new assays on faunal remains from Levels 119, 117, 114, 108, and 106 were run at Queen’s University in Belfast. There continue to be date inversions in the Lower Magdalenian range of levels that may be explained by a combination of intensive anthropic and rodent activity, major rock fall, slope wash and gravity-caused object movements, as well as possible problems in following some thin levels during excavations over a large area and across many years of work in the cave vestibule interior, particularly in the absence of any layers that are culturally sterile or even poor. Nonetheless, the coherent age of the Initial Magdalenian is fully confirmed by a new date from Level 21 in the vestibule front at ca. 22,000–20,500 cal BP), as is the general age range of the Lower Magdalenian (ca. 20,500–18,000 cal BP).

The Role of Agentive and Physical Forces in the Neural Representation of Motion Events.

How does the brain represent information about motion events in relation to agentive and physical forces? In this study, we investigated the neural activity patterns associated with observing animated actions of agents (e.g., an agent hitting a chair) in comparison to similar movements of inanimate objects that were either shaped solely by the physics of the scene (e.g., gravity causing an object to fall down a hill and hit a chair) or initiated by agents (e.g., a visible agent causing an object to hit a chair). Using an fMRI-based multivariate pattern analysis (MVPA), this design allowed testing where in the brain the neural activity patterns associated with motion events change as a function of, or are invariant to, agentive versus physical forces behind them. A total of 29 human participants (nine male) participated in the study. Cross-decoding revealed a shared neural representation of animate and inanimate motion events that is invariant to agentive or physical forces in regions spanning frontoparietal and posterior temporal cortices. In contrast, the right lateral occipitotemporal cortex showed a higher sensitivity to agentive events, while the left dorsal premotor cortex was more sensitive to information about inanimate object events that were solely shaped by the physics of the scene.

Sistem Buka-Tutup Sebuah Pintu Rumah Menggunakan Face Recognition Berbasis Mikrokontroler

Internet of Things technology is now widely used in all aspects of life including the application of smart homes. An automation technology is used to facilitate access at home, as well as access to the entrance of the house that uses facial image recognition (face detection). Human facial image recognition is one of the important technologies that continues to develop in the field of computer vision with its application in biometric recognition systems. One of them is by using the facial image recognition method, the Haar Cascade Classifier Algorithm. Therefore, a house door open-close system with facial recognition is designed using the ESP32-Cam module as a camera sensor. Face images were taken using the ESP32-Cam camera and processed using the ESP32 Microcontroller through the Arduino IDE program. Recognition results will be forwarded from the microcontroller to the PIR sensor, DC motor, buzzer, LED and website. The test result of this system is that if the detected face ID matches the data base, the PIR sensor will be active to detect the movement of objects in front of the entrance. When motion is detected, the buzzer as an alarm will be ON and the door will open and close automatically. If Face ID is not detected then the door will not open.

A new tilted aerial robotic platform: Modeling and control

Aerial Manipulators are considered in modern applications due to their essential features that have the maneuverability of Unmanned Aerial Vehicles (UAVs) and abilities of robotics arms. One of the primary challenges encountered by aerial manipulators is their inability to maintain a consistent orientation though the duration of flight. This limits the application of aerial manipulators for movement of fragile and liquid objects that should not change their orientation during the flight. To solve this issue, this study introduced a new Aerial Robot Platform (AR-P) which can decouple all motions by configuring tilting rotors into the structure of the AR-P. The AR-P consists of a Tilted-Rotor Quadcopter (T-RQ) and three linked Aerial Robot Arm (AR-A) that have a gripper to grasp objects. The AR-P with this new mechanism of tilting parts overcomes the problem of manipulation limitations by adjusting the direction of the thrusted rotors according to the exerted forces of the grasped object. The new dynamics model of the AR-P is derived using the Lagrange-d'Alembert approach. A special Multi Input Multi Output (MIMO) Proportional Derivative (PD) controller based on Computed Torque Control (CTC) is designed for the developed AR-P. The method of nonlinear least squares is applied to obtain the optimal gains of the over-looped PD controller. The simulation results showed the ability of the developed CTC to track the required joint angle of each the T-RQ and each link of the AR-A with minimizing steady state errors and without overshooting. The implemented controller showed its robustness against external disturbances in form of wind conditions. On one hand, the controller is tested considering traditional aerial manipulator. On the other hand, the controller is tested by our new tilted aerial robot platform. The comparison results of the flight scenario between the new tilted aerial manipulator and the traditional one approved the advantage of the proposed new tilted AR-P to transport the grasped objects in fixed orientation.

Exploring Complexity in Bronze Age Exchange Networks by Revisiting the Bronze Mirrors of Central Asia and China

The ever-growing body of research on trans-Eurasian exchange during the third–first millennium bce continues to improve understanding of mechanisms that facilitated the movement of objects, materials, ideas, and even people. However, whether bronze mirrors in Central Asia and China represent the exchange of technological knowledge or movement of the objects themselves remains unresolved, as researchers require extensive knowledge of huge quantities of data generated during the Soviet Central Asia campaigns of the mid twentieth century. The often confusing, impenetrable excavation reports, combined with required knowledge of Chinese, Russian and English, have caused much confusion about dates and contexts. This article presents and compares data published in Russian and Chinese reports. By clarifying the chronology for mirrors in Central Asia and China, we challenge simplistic theories of object diffusion and spread that persist in studies of trans-Eurasian exchange. We argue that the early second-millennium bce appearance of mirrors in western and northwestern China resulted from different exchange mechanisms specific to each local socio-cultural context. This demonstrates not only the complexity of interactions at the group and individual levels, but also how these factors can be integrated with data-driven analyses to explore the role they played in large-scale Bronze Age exchange networks.

Models for determining the orientation of the solar battery of an observation spacecraft relative to the Sun during object survey and retargeting

Simplified models and algorithms have been developed to estimate the current value of the angle between the normal to the plane of the solar panel and the sun vector at the time of object survey and during the reorientation of the Earth remote sensing spacecraft, taking into account the relative movement of observation objects in the field of view of the spacecraft. The models differ from the existing ones in that they do not require knowledge of the spacecraft control programs at pitch, roll and yaw angles at each moment of time of the process of its targeted functioning and re-targeting, Based on the obtained models, a software module that does not require large computing resources used in the simulation software package simulating targeted functioning of the space surveillance system has been developed, taking into account the long-term orbital motion of satellites, changes in the parameters of the orbit, the sun vector and other factors. The adequacy of the developed models was verified by visualizing the orbital motion of the spacecraft and its turns during re-targeting, as well as by comparing the simulation results with the results of analytical calculation for particular cases of the initial data. Examples of the implementation of software windows are given.

Research on Visual Fatigue Caused by Color Combinations in Civil Aircraft Cockpit Display Interfaces

In order to analyze the visual fatigue degree of the foreground and background color combination of the display of civil aircraft cockpit, the visual afterimage experimental paradigm is used in the present study. Objective eye movement data and subjective reported visual afterimage color were collected. The difference of pupil diameter under different color combinations showed that background color had a significant effect on visual fatigue. In addition, black background color can lead to the lowest degree of visual fatigue, followed by brown background color. Moreover, blue background color was the most likely to cause visual fatigue. The subjective report data showed that the visual afterimage color was related to the foreground and background color combination. In the combination of background color and foreground color, the ratio of visual afterimage color and background color is the highest, followed by the foreground color, and the complementary color of foreground color or background color. Based on the above results, the color design suggestions of civil aircraft cockpit interface are proposed in this work.

Image deblurring: comparison and analysis

Technological advancements and the advent of digital devices and media make images an important part of today’s social life. Image blurring is a common challenge that results from multiple factors such as object movement, camera shake, and raindrops, among others. Image deblurring has progressively become an important field of image restoration as directed by research findings. After research for more than five decades, significant research efforts have yielded useful technologies of image deblurring. This article provides an overview of the current knowledge on image deblurring technology by focusing on the classical methods and modern trends in the field. The article reviews the conventional methods and achievements made in past studies using evidence from 34 scholarly articles. The article also examines the application of algorithms in specific deblurring methodologies adopted in recent works. It covers the recent trend of learning-based models used to restore images and their effectiveness. They include Convolutional Neural Networks, Recurrent Neural Networks and Graph Convolutional Networks. Novel deep-learning deblurring techniques are also explored. Based on the findings, issues of concerns, opportunities and direction for future research are provided to advance image deblurring technologies.

Kinematic target surface sensing based on improved deep optical flow tracking.

Reconstruction of moving target surfaces based on active image sensing techniques, such as phase-shifting profilometry, has attracted intensive research in recent years. The measurement error caused by object motion can be addressed successfully by tracking the object movement. However, it either requires high-cost color imaging equipment or is limited by the assumption of 2D translation movement. Therefore, this paper proposes what we believe to be a new method to reconstruct the kinematic object surfaces with any 2D movement sensed by affordable monochrome camera. An improved RAFT optical flow algorithm is proposed to track the object based on the object fringe pattern image directly. The feature points on the object are retrieved immune to the fringe pattern illumination. Then, the RANSAC algorithm and an iteration selection process are employed to select feature points with high quality optical flow. At last, the motion is described mathematically, and the dynamic object is reconstructed successfully. Experiments are presented to verify the effectiveness of the proposed method.
