Abstract:
Plastic welding method is a widely used technology for the welding of pressure and vacuum bags using plastic valves. Conducting this process with traditional methods creates disadvantages in terms of production speed, product quality and economical aspects. Today, assembly costs make up the majority of total production costs, manufacturers pay more attention to assembly automation and work in this direction in order to reduce costs, speed up the production process and increase efficiency. In this study, it is aimed to design and manufacture a single Automatic Valve Welding Machine that can do all of these operations and integrated automation system instead of cutting, punching and plastic welding process that can be performed with multiple machines and workers. In this context, a new automated machine was designed in 3 D, and engineering analyzes were carried out to manufacture a prototype. In design, the machine has been made suitable for developing technology by using PLC (Programming Logic Controller) and pneumatic system. In addition, static analyzes of the machine were made. With the inclusion of a production-specific automatic controlled plastic welding machine, manufacturing can be done faster, with higher quality, lower costs and less wastage compared to the traditional manufacturing process.

Abstract:
The industry is at the heart of a country’s development, and robot automation is the key to this. The automation of industrial robots is extremely beneficial to industrial development. Although China has been increasing its investment in industrial robot automation and control research, there are still many problems in the field of automation and control in the application of industrial robot technology, and there is still a certain gap between the developed countries. On the one hand, this is a serious obstacle to the development of industrial robotics in China, and on the other hand, it has a direct impact on the automation of industrial production, which has a very restrictive effect on industrial development. Therefore, it is necessary to focus on the value of computer technology, automation control technology, and sensor technology in the field of automation. The use of industrial robots can replace monotonous manual labour, reduce the intensity of operations, and increase productivity through high operational precision values. Scientific progress has driven the development process of industrial automation to a new level, allowing fully automated production equipment to become mainstream and gradually replace manual operations. In recent years, the development of industrial automation has led to the development of a series of related industries, of which automated manipulators are one. As a new automatic production line operation equipment, the development of manipulators can greatly improve the automation production level of enterprises and improve labour efficiency. This paper explores the development status of automated manipulators and explore the optimal motion path of manipulators in automatic control engineering by combining simulated annealing algorithm and PID algorithm, so as to greatly enhance the application of truss manipulators in production lines.

Abstract:
Gas content measurement is a common technique in the prevention of coalmine gas disasters. During the measurement, the gas desorption amount of field coal samples needs to be obtained by an instrument working under the principle of gas collection by water displacement (GCWD). The instrument is poorly automated, and susceptible to the influence of subjective factors. To overcome these defects, this paper designs an automatic detector of gas desorption, aiming to realize automated detection. Firstly, the authors analyzed the gas desorption detection process, and clarified the contents and features of the information to be collected. On this basis, the hardware and software systems of the multi-data automatic detector were developed based on digital circuit design and multi-sensor detection. To further improve the measuring accuracy of gas desorption, the multi-range multi-stage mode was introduced to the automatic detector. Application results show that the proposed detector can automatedly collect and store gas desorption amount, ambient pressure, and temperature, greatly improve the degree of automation, and minimize the influence of subjective factors. The popularization of this detector will make gas desorption measurement more efficient and effective, laying a solid basis for the prevention of coalmine gas disasters.

Abstract:
Currently, the spring machine tool is fixed by means of manual clamping and positioning by bolts. The automation of the tool change is low, and the accurate value of the tool position cannot be determined. The automatic tool change system for spring machine was designed by using the standard functional parts of the automatic tool change system of the machining center. It mainly includes the design of the automatic loose clamp device and that of the multispindle automatic tool change arm. After static analysis, the deformation of the automatic tool change arm is 0.153 mm, which satisfies the requirements for usage. Kinematic analysis of the designed automatic tool change arm was carried out. After actual verification, the designed automatic tool change system of spring machine realizes the functions of the tools automatic replacement and positioning of the spring machine, which improves the automation of the spring forming equipment.

Abstract:
A significant problem in the automatic design of 3D graphics is the configuration of the lighting for a scene. The number of lights included, and the properties of these lights, has an enormous impact on what a viewer can judge about the content (the objects), properties (the geometric characteristics and spatial relations of the objects) and other aesthetic qualities of a scene. The traditional approach to lighting design for image synthesis is based on manual design methods, whereby users interactively specify values of lighting parameters, render the scene, and modify the lighting parameters until the desired visual properties of the scene are achieved. Non-expert users encounter a number of difficulties in selecting the appropriate lighting parameters, as the process requires both a subtle technical and aesthetic understanding of lighting in computer graphics. In this thesis, perceptual aspects such as contrast and the non-linear characteristics of our perceptual response to colour are combined with practical studio lighting techniques and a novel treatment of shadows, to yield an extension to existing perceptual approaches to lighting design. This so-called ideal lighting approach optimises the lighting configuration for a scene with respect to a set of absolute perceptual metrics. An intuitive approach to lighting design, lighting-by-example, is also proposed and extensively explored in forms that exploit both the perception-based lighting framework and a new wavelet formulation. User studies are conducted both to configure the perception-based lighting objective function and to evaluate the performance of the proposed lighting design approaches. Finally, we develop an interactive interface for the lighting design process that incorporates both the ideal lighting and lighting-by-example approaches.

Abstract:
Evolvable Hardware (EHW) is a promising area in electronics today. Evolutionary Algorithms (EA), together with a circuit simulation tool or real hardware, automatically designs a circuit for a given problem. The circuits evolved may have unconventional designs and be less dependent on the personal knowledge of a designer. Nowadays, EA are represented by Genetic Algorithms (GA), Genetic Programming (GP) and Evolutionary Strategy (ES). While GA is definitely the most popular tool, GP has rapidly developed in recent years and is notable by its outstanding results. However, to date the use of ES for analogue circuit synthesis has been limited to a few applications. This work is devoted to exploring the potential of ES to create novel analogue designs. The narrative of the thesis starts with a framework of an ES-based system generating simple circuits, such as low pass filters. Then it continues with a step-by-step progression to increasingly sophisticated designs that require additional strength from the system. Finally, it describes the modernization of the system using novel techniques that enable the synthesis of complex multi-pin circuits that are newly evolved. It has been discovered that ES has strong power to synthesize analogue circuits. The circuits evolved in the first part of the thesis exceed similar results made previously using other techniques in a component economy, in the better functioning of the evolved circuits and in the computing power spent to reach the results. The target circuits for evolution in the second half are chosen by the author to challenge the capability of the developed system. By functioning, they do not belong to the conventional analogue domain but to applications that are usually adopted by digital circuits. To solve the design tasks, the system has been gradually developed to support the ability of evolving increasingly complex circuits. As a final result, a state-of-the-art ES-based system has been developed that possesses a novel mutation paradigm, with an ability to create, store and reuse substructures, to adapt the mutation, selection parameters and population size, utilize automatic incremental evolution and use the power of parallel computing. It has been discovered that with the ability to synthesis the most up-to-date multi-pin complex analogue circuits that have ever been automatically synthesized before, the system is capable of synthesizing circuits that are problematic for conventional design with application domains that lay beyond the conventional application domain for analogue circuits.

Abstract:
El desarrollo de tecnologías para sintetizar nuevos genomas e introducirlos dentro de hospedadores con sus respectivos cromosomas naturales inactivados abre las puertas a nuevos horizontes en biología sintética. Es de suma importancia aprovechar la habilidad de usar métodos computacionales para predecir y optimizar genomas sintéticos antes de llevar a cabo su síntesis. El objetivo de esta tesis es propulsar la ingeniería de genomas sintéticos de una célula procariota y otras dos eucariotas usando modelos cuantitativos a escala genómica. Así pues, he desarrollado una nueva metodología para el diseño automatizado de genomas sintéticos que se basa en una optimización que computacionalmente imita la evolución natural de genomas. Primero, he abordado el diseño de la red genómica transcripcional de Escherichia coli con adaptación a entornos cambiantes. Aplicando métodos de ingeniería reversa a los datos masivos disponibles de la transcripción y señalización para la bacteria, tratamos entender los principios de diseño que determinan la regulación de su transcriptoma. Encontramos que el genoma de E. coli puede ser rediseñado de tal forma que tenga una estructura reguladora transcripcional más simple manteniendo aún la respuesta fisiológica global ante ambientes fluctuantes. Estos genomas son más sensibles y muestran una respuesta más robusta ante ambientes agresivos. Segundo, he estudiado cómo los virus reprograman los chasis celulares de sus hospedadores asumiendo que existen mecanismos por los cuales los virus son capaces de superar con éxito las defensas expuestas por los hospedadores y modificar la expresión de sus genes en su propio beneficio. He desarrollado un nuevo modelo cuantitativo de la regulaci\'on transcripcional a nivel genómico de Arabidopsis thaliana para explorar el paisaje de posibles genomas rediseñados. Encontré un conjunto básico de genes del hospedador cuyos silenciamiento o sobre-expresión dieron pie a la predicción de perfiles de transcripción que s

Abstract:
Abstract In many industrial applications, such as product prototype development, automation of inspection process can greatly improve product quality and product development cycle, time. This paper discusses a development of a vision aided automatic inspection using Coordinate Measuring Machine (CMM). We seek to integrate the flexibility afforded by computer vision systems with the precision of numerically controlled coordinate measuring machines to achieve a fully automatic and reliable inspection of the industrial parts. The 3-D design information and part specification from computer-aided design file is used for inspection point placement and CMM path planning. The proposed system demonstrates that optimal collision-free inspection paths can be efficiently generated for geometrically complex parts consisting of multiply intersecting features. This is made possible by using iterative subdivision of surfaces for point placement coupled with, efficient 3-D collision avoidance and path planning. The paper discusses different algorithms used, and presents experimental results.

Abstract:
Manual construction of design tolerance charts is a popular technique for analyzing tolerance accumulation in parts and assemblies, even though it is limited to one-dimensional worst-case analysis. Since charting rules are GD&T (geometric dimensioning & tolerancing) specification dependent, and the user has to remember all the different rules to construct a valid tolerance chart, manual charting technique is time-consuming and error-prone. The computer can be used for automated tolerance charting, which can relieve the user from the tedious and error-prone procedure while obtain the valid results faster. The automation of tolerance charting, based on the ASU GD&T mathematical model, involves (1) automation of stackup loop detection, (2) formulation of the charting rules for different geometric tolerances and determination of the closed form function for statistical analysis, (3) automatic part arrangement for an assembly level chart analysis, (4) development of the algorithms for chart analysis and automatic application of the charting rules. Since the authors’ previous DETC/CIE’03 paper already discussed tasks 1~2 and part of task 4, this paper will focus upon task 3, i.e. virtual part arrangement in assemblies for tolerance charts, and update the analysis algorithm (related to task 4). These two papers together will provide a complete coverage of automated tolerance charting technique popularly used in industry. The implementation will be briefly discussed as well, and case studies will be provided to demonstrate the approach to virtual part arrangement.

Abstract:
Increasing concerns about global warming, resource depletion, and ecosystem degradation are pushing manufacturing enterprises to consider environmental impacts of the products they make. Tools such as Life Cycle Assessment (LCA) has been developed to quantify environmental performance of a product, yet the implementation of LCA requires a significant amount of time/resources and its potential in assisting eco-design has been limited. Research has been done to conduct automatic LCA using the simplified database for electronics or to investigate the environmental impact of electricity consumption in a manufacturing process. However, a comprehensive and automated approach is in need to perform LCA analysis for a product considering all related materials and manufacturing processes. In this research, a framework for automating LCA analysis for eco-friendly product design has been developed and implemented with a computer program. A case study has been conducted using the proposed automatic LCA tool to perform life cycle analysis in the design process. The result of the tool can, with minimal time required, provide detailed distribution of life cycle impact indicators among direct inputs and assist in making design decisions to reduce the environmental footprints.

Abstract:
Manual construction of tolerance charts is a popular technique for analyzing tolerance accumulation in parts and assemblies. But this technique has some limitations: (1) it only deals with the worst-case analysis, and not statistical analysis (2) it is time-consuming and errorprone (3) it considers variations in only one direction at a time, i.e. radial or linear. This paper proposes a method to automate 1-D tolerance charting, based on the ASU GD&T global model and to add statistical tolerance analysis functionality to the charting analysis. The automation of tolerance charting involves automation of stackup loop detection, automatic application of the rules for chart construction and determination of the closed form function for statistical analysis. The automated analysis considers both dimensional and geometric tolerances defined as per the ASME Y14.5 – 1994 standard at part and assembly level. The implementation of a prototype charting analysis system is described and two case studies are presented to demonstrate the approach.

Abstract:
The objective of the research described here is to develop and demonstrate use of automatic design methods for pre-swirl nozzles. Performance of pre-swirled cooling air delivery systems depends critically on the design of these nozzles which is subject to manufacturing and stress constraints. The best solution may be a compromise between cost and performance. Here it is shown that automatic optimisation using computational fluid dynamics (CFD) to evaluate nozzle performance can be useful in design. A parametric geometric model of a nozzle with appropriate constraints is first defined and the CFD meshing and solution are then automated. The mesh generation is found to be the most delicate task in the whole process. Direct hill climbing (DHC) and response surface model (RSM) optimisation methods have been evaluated. For the test case considered, significant nozzle performance improvements were obtained using both methods, but the RSM model was preferred.

Abstract:
With the advent of high-speed personal computers and modern algorithms, it is possible for the designer to create a wide variety of coating designs automatically. This capability is important because, in many cases, the designer may not have the time and resources to craft a design manually. For unusual designs, where there may be little or no theory to use as a guide, automatic design is indispensable.

Abstract:
Abstract A shape optimization capability which is fully integrated with geometry data is developed in this paper. A key feature of the system is the direct use of parametric solid model as the primary design model for shape optimization. This choice leads to a tight coupling between optimization and geometry, a highly desirable feature for an automated design environment. The approach exploits the parametric engine of the solid modeler to update the geometry at the end of each iteration. Responses are generated using polyFEM, a p-adaptive solver supported by a fully automatic three dimensional p-element mesh generator. It is illustrated that the use of p-adaptive technology and parametrized solid model assist us in achieving a high degree of automation.
