Light-driven transport of microparticles with phase-gradient metasurfaces.

Optical tweezers have opened numerous possibilities for precise control of microscopic particles for applications in life science and soft matter research and technology. However, traditional optical tweezers employ bulky conventional optics that prevents construction of compact optical manipulation systems. As an alternative, we present an ultrathin silicon-based metasurface that enables simultaneous confinement and propulsion of microparticles based on a combination of intensity and phase-gradient optical forces. The metasurface is constructed as a water-immersion line-focusing element that enables trapping and transport of 2μm particles over a wide area within a thin liquid cell. We envisage that the type of multifunctional metasurfaces reported herein will play a central role in miniaturized optical sensing, driving, and sorting of microscopic objects, such as cells or other biological entities.

Strength Pareto Evolutionary Algorithm Based on New Fitness Strategy for Multi Objective Knapsack Problem

problems. Many different experiments have shown that the evolutionary algorithm Strength Pareto Evolutionary Algorithm 2 (SPEA2) outperforms other approaches, and this makes it an excellent candidate for inclusion in the final design. According to Strength, one of SPEA2's core concepts, the population is sorted into niches based on the Pareto Front idea. With regard to outcomes this technique has a flaw that is mitigated by adding a fitness density estimator. Weakness in Strength is addressed with an approach called Strength by objective, which aims to include solution who do not dominate or are dominated by others inside the process. In this paper, the results will show a clear superiority of the proposed method comparing with the original method in solving the multi-objective Knapsack problem using three sizes of the Knapsack and the problem size of 750 items which is generated randomly. The comparison results between the proposed method and the other algorithms show outperformance of the Proposed algorithm using the dominance inductor showed the superiority of the proposed algorithm by a percentage of more than 1 %, Thanks to a highly diverse population and the inclusion of solutions that can be improved, the (SPEA2) algorithm's performance has been vastly enhanced by the Objective sorting mechanism

A Statistical Approach to Classification: A guide to hierarchical cluster analysis in agricultural communications research

Classification, the sorting of similar objects or organisms into groups based on shared qualities and characteristics, is how we make sense of the world. As the field of agricultural communication and our understanding of media effects becomes more complex, it is important to have approaches that allow for a valid and reliable method of classifying units of analysis — whether they are texts, people, or other artifacts — into groups based on theoretically sound variables. This paper discusses one method of classification, the hierarchical cluster analysis, and how this method may be applied by 1) Developing Variables for Study, 2) Choosing a Sample, 3) Removing Unnecessary Variables, 4) Running the analysis, and 5) Interpreting Clusters. This professional development paper suggests this method could have positive implications for agricultural and science communication research including increased validity and reliability, rigorous development, and deeper understanding of mass communication theory. In addition, we provide recommendations for future research such as audience segmentation in agricultural and science communication research.

Design and production of an automatic solid waste sorting machine with smart digital counter

Sorting of objects is the first step of a waste management process. These objects should be sorted according to the type of material for effective waste recycling. Therefore, the focus of this work is to design and produce an automated sorting machine that can be used to sort metals and non-metals autonomously. The automatic sorting machine with a smart digital counter was designed to use a microcontroller (Arduino Mega) to control the conveyor systems which consist of the conveyor support, driving unit and the driven unit. The sorting mechanisms consist of the inductive sensor, infrared Sensor and the actuating system using servo motor. The conveyor system helps in the conveyance of objects towards the sorting chute. The actuating system receives signal from the microcontroller and the device does the sorting of the objects based on their characteristics while the digital counter counts the number of metallic objects dropping into the designated cart. The time taken for the inductive sensor to sense an object, the waiting period for the servo motor to be actuated and the time taken for the counter to count after a metallic object is sensed are 1s, 2s and 1s respectively. After its development, it was tested and observed to meet the design requirements.

FeetBack-Redirecting touch sensation from a prosthetic hand to the human foot.

Adding sensory feedback to myoelectric prosthetic hands was shown to enhance the user experience in terms of controllability and device embodiment. Often this is realized non-invasively by adding devices, such as actuators or electrodes, within the prosthetic shaft to deliver the desired feedback. However, adding a feedback system in the socket adds more weight, steals valuable space, and may interfere with myoelectric signals. To circumvent said drawbacks we tested for the first time if force feedback from a prosthetic hand could be redirected to another similarly sensitive part of the body: the foot. We developed a vibrotactile insole that vibrates depending on the sensed force on the prosthetic fingers. This self-controlled clinical pilot trial included four experienced users of myoelectric prostheses. The participants solved two types of tasks with the artificial hands: 1) sorting objects depending on their plasticity with the feedback insole but without audio-visual feedback, and 2) manipulating fragile, heavy, and delicate objects with and without the feedback insole. The sorting task was evaluated with Goodman-Kruskal's gamma for ranked correlation. The manipulation tasks were assessed by the success rate. The results from the sorting task with vibrotactile feedback showed a substantial positive effect. The success rates for manipulation tasks with fragile and heavy objects were high under both conditions (feedback on or off, respectively). The manipulation task with delicate objects revealed inferior success with feedback in three of four participants. We introduced a novel approach to touch sensation in myoelectric prostheses. The results for the sorting task and the manipulation tasks diverged. This is likely linked to the availability of various feedback sources. Our results for redirected feedback to the feet fall in line with previous similar studies that applied feedback to the residual arm.

Does Each of Us Think Our Own Universal? An Averroean Challenge for (Aquinas and) Hervaeus Natalis

AbstractThis paper aims to address a problem faced by any philosopher who treats universals as intentional objects: in defending this thesis, aren't they committed to the view that each of us thinks an individuated universal, since each of us, when thinking of a universal, must have our own intentional object? This problem, which is mentioned by Brentano at the turn of the twentieth century, originated in the Middle Ages in debates initiated by Averroes about the nature of the intellect. It shows up in the later Aquinas, due to his theory of the verbum, which might be interpreted as a sort of intentional object, but it is solved without too much difficulty. It is later found in Hervaeus Natalis, who does accept intentional objects; in contrast to Aquinas, it is not clear that Hervaeus has a good solution to the problem. After first presenting the problem, this paper then turns to its medieval origins by analyzing its occurrence in Aquinas's criticism of Averroes. It then explains why Hervaeus has more difficulties than Aquinas in solving the problem. It concludes with a systematic reflection on the various possible solutions to the problem.

Design & Fabrication of Automatic Color & Weight-Based Sorting System on Conveyor Belt

Object sorting is a basic process that is employed in a variety of disciplines in our daily lives for our convenience. Previously, the sorting operation was done by hand using labor justification. Because product quality does not remain consistent during the typical sorting process, it adds complexity to the segregation of products based on their height, color, size, and weight. This method is also time-consuming and slows down output. To overcome these problems, Low-Cost Automation (LCA) has been implemented in the sorting system, which aims to reduce production time, labor cost, and processing complexity, improve product quality, increase production rate, etc. So, in this project, an effective method has been developed for automatically sorting the object based on color and weight. This method uses a conveyor belt, strain gauge load cell, DC motor, servo motor, TCS 34725 RGB color sensor, LCD, LED, and LDR to identify, separate, and collect the objects according to their color and weight. Arduino is used to controlling all the processes. This work has sorted three types of colors -red, , green, and blue, and the weight of different ranges. Firstly, the weights have been sorted by load cell, and then the desired colors have been sorted by color sensor. A bucket at the end of the conveyor belt can be rotated depending on the signal sent from the Arduino to collect the box. The collecting box has a specific portion in a particular color. Hence, it could be rotated at a specific angle for an exact weight for red, blue, and green colors.

Development of Multi-Robotic Arm System for Sorting System Using Computer Vision

This paper develops a multi-robotic arm system and a stereo vision system to sort objects in the right position according to size and shape attributes. The robotic arm system consists of one master and three slave robots associated with three conveyor belts. Each robotic arm is controlled by a robot controller based on a microcontroller. A master controller is used for the vision system and communicating with slave robotic arms using the Modbus RTU protocol through an RS485 serial interface. The stereo vision system is built to determine the 3D coordinates of the object. Instead of rebuilding the entire disparity map, which is computationally expensive, the centroids of the objects in the two images are calculated to determine the depth value. After that, we can calculate the 3D coordinates of the object by using the formula of the pinhole camera model. Objects are picked up and placed on a conveyor branch according to their shape. The conveyor transports the object to the location of the slave robot. Based on the size attribute that the slave robot receives from the master, the object is picked and placed in the right position. Experiment results reveal the effectiveness of the system. The system can be used in industrial processes to reduce the required time and improve the performance of the production line.

THE CONCEPT COLOUR IN ESSAYS ON ART WRITTEN IN ENGLISH: A COMPARATIVE ANALYSIS OF JOHN BERGER’S AND JED PERLS’S ESSAYS ABOUT HENRI MATISSE

Introduction. The paper is devoted to the analysis of the concept COLOUR verbalized in the essays about Henri Matisse written by John Berger and Jed Perl. The context for the linguistic studies of the concept of COLOUR is provided through a brief outline of the linguistic approaches to the analysis of this concept and identification of the relation of the research on the verbalized concept COLOUR with the attempts to solve the question about the connection between language and thought as one of the key linguistic questions. The conception of A. Prikhodko about different types of concepts depending on their roles in constituting certain types of discourse is employed to identify the concept COLOUR as autochthonous, having the key role in the art-critical discourse. The purpose of the study is reveal the similarities and differences in the verbalization of the concept COLOUR in Berger’s and Perl’s essays. Methodological foundations of the research are the principles of the cognitive-discursive paradigm in modern linguistics. The following methods were used to analyse the data: analysis of definitions of lexemes, componential analysis, interpretation in the context, cognitive and pragmatic interpretation, comparative analysis. The study has revealed that the essays share the positive evaluation of the art of Matisse. However, the essays have different communicative aims with Berger striving to explain the creative genius of Matisse and Perl intending to get the readers interested in Matisse’s retrospective exhibition. Thus the concept COLOUR plays the key role in Berger’s essays as a means of interpretation of Matisse’s art, whereas it shares this role with three other concepts in Perl’s essay. The analysis has revealed a number of the similarities in the actualization of the concept COLOUR in both essays. This concept is verbalized by the lexeme colour / color or the names of specific colours; in both essays the conceptual metaphor COLOUR IS SOUND is used; in both essays there are contexts of the actualization of the conceptCOLOUR which perform such functions: discussing the main principle of how Matisse used his colours, placing Matisse in the context of the art styles and comparing Matisse with other artists. Such similarities make the conclusion that it is possible to provide some sort of objective, well-grounded interpretation of the works of art plausible.

Smart Living in the Digital Age


 
 
 The digital age is the age of smart systems. Smart living has already emerged as the conceptual hallmark of the digital future. We have we or will soon have smart homes, cities, and all sorts of smart interconnected objects. This paper deals, firstly, with the meaning of smart as related to the Greek concept of metis or cunning intelligence, the contexts of use being not only of human beings but also of gods, animals and artificial devices. The 19th century application of the concept referred to devices in general and in the 20th century to digital devices and systems in particular for which the leading sense is human intelligence. At present, it is not human but digital intelligence that leads the meaning of smart. Artificial smart systems receive their goals from the outside even if they can further develop such goals, giving the impression that they have conceived their goals on their own. They behave as if they were guided by a 'who' while in fact it is just a reified one, or a 'what'. The difference between who and what is the basis of ethical thinking in the age of smart systems.

Foundation of the Manipulation Technology for Tiny Objects Based on the Control of the Heterogeneity of Electric Fields

Effective sorting and extraction of tiny plastic objects is becoming increasingly important for manufacturing high-quality recycled plastics. Herein, we designed a manipulation device for tiny objects that can drive multiple target objects individually. This type of device has a potential to sort tiny pieces of a wide variety of materials, not strongly depending on their physical properties, by combining different detection meanings. In this study, two types of devices were tested as the basic components of the proposed device. One of them had a single object-holding point and the other had two of them. These holding points consisted of strip-shaped electrodes facing each other. The high voltage applied to the facing electrodes created forces heading toward the object-holding points caused by the heterogeneity of the electric field in the devices. The forces created in these devices were determined from the motion analysis of a glass sphere, which is a model for target objects, and a numerical simulation. The results indicate that dielectrophoretic forces are dominant at locations that are sufficiently remote from the holding point, and the Coulombic force caused by dielectric barrier discharge is dominant near the high-voltage electrodes with the holding point. Moreover, the transfer of a glass sphere from one holding point to an adjacent point was successfully demonstrated.

The Worst Case: Planetary Defense against a Doomsday Impactor

Current planetary defense policy prioritizes a probability assessment of risk of Earth impact by an asteroid or a comet in the planning of detection and mitigation strategies and in setting the levels of urgency and budgeting to operationalize them. The result has been a focus on asteroids of Tunguska size, which could destroy a city or a region, since this is the most likely sort of object we would need to defend against. However a complete risk assessment would consider not only the probability of an impact but also the magnitude of its consequences, which in the case of an object of Chicxulub size could be the end of civilization or even human extinction. This paper argues that a planetary defense policy based on a complete (or one could say genuine) risk assessment would justify expenditures much higher than at present.

Programmable micro-transfer-printing for heterogeneous material integration

Micro-transfer printing is an emerging assembly technique to deterministically transfer ink comprising micro-/nano-objects from a donor substrate to a receiver substrate. This technique has generated increasing interest over the last decade due to its unique capability of integrating diverse heterogeneous materials into various structures and layouts. The growing number of applications enabled by micro-transfer printing includes flexible electronics, sensors, photovoltaics, and micro-LED displays. This work presents a micro-transfer printing approach, which relies on thermally induced adhesion modulation of shape memory polymer materials. An individually addressable micro-fabricated resistive heater array is used to locally deliver the heat for transfer pixel actuation. Selectively transferring chips from a closely packed microchip donor array (pitch: 100 µm, size: 50 × 50 µm2) is demonstrated. The transfer head can be dynamically configured to assemble micro-objects in arbitrary patterns, allowing digital manufacturing, object sorting, or in-line assembly correction of defects. These capabilities, together with the simple and robust structure of the transfer head, can enable high process scalability and flexibility for heterogeneous material integration.

Bio-Medical Waste Management System

Abstract: Sorting of products is a very difficult industrial process. Continuous manual sorting creates consistency issues. This paper describes a working prototype designed for automatic sorting of objects based on the colour. We are using Pi camera to detect the object and the Raspberry Pi microcontroller was used to control the overall process. The identification of the biomedical Waste is based on the image processing using Pi camera module. Two conveyor belts were used, each controlled by separate Servo motors. The first belt is for placing the product to be analysed by the pi camera module, and the second belt is for moving the container, having separated compartments, in order to separate the products. The experimental results promise that the prototype will fulfil the needs for higher production and precise quality in the field of automation.

Learn multi-step object sorting tasks through deep reinforcement learning

AbstractRobotic systems are usually controlled to repetitively perform specific actions for manufacturing tasks. The traditional control methods are domain-dependent and model-dependent with cost of much human efforts. They cannot meet the new requirements of generality and flexibility in many areas such as intelligent manufacturing and customized production. This paper develops a general model-free approach to enable robots to perform multi-step object sorting tasks through deep reinforcement learning. Taking projected heightmap images from different time steps as input without extra high-level image analysis and understanding, critic models are designed to produce a pixel-wise Q value map for each type of action. It is a new trial to apply pixel-wise Q value-based critic networks to solve multi-step sorting tasks that involve many types of actions and complex action constraints. The experimental validations on simulated and realistic object sorting tasks demonstrate the effectiveness of the proposed approach. Qualitative results (videos), code for simulated and realistic experiments, and pre-trained models are available at https://github.com/JiatongBao/DRLSorting

Complex Analysis of the Necessary Geometric Parameters of the Tested Component in the Ring-Core Evaluation Process

Abstract Residual stress measurement in different sorts of mechanical and mechatronic objects has become an important part of the designing process and following maintenance. Therefore, a sufficient experimental method could significantly increase the accuracy and reliability of the evaluation process. Ring-Core method is a well-known semi-destructive method, yet it is still not standardized. This work tries to improve the evaluation process of the Ring-Core method by analyzing the influence of the necessary geometric parameters of the investigated object. Subsequently, residual stress computation accuracy is increased by proposed recommendations.
