Government agencies and companies are establishing and promoting digital transformation strategies in various industrial fields, and are leading the era of the 4th industrial revolution through successful technological innovation. In this time of change, we can see many stories of global companies Nike and Starbucks as successful examples of digital transformation. These two companies are showing successful results through digital transformation. Domestic companies are also conducting digital innovation based on mobile, cloud, IoT, artificial intelligence, and AR/VR technologies, and are establishing RPA (Robotic Process Automation) processes for high efficiency and high productivity. In this paper, we introduce the 3D digital twin space construction automation process technique using data from the entire construction cycle of design, construction, and maintenance of the construction industry, and look into the digital transformation strategy of the construction industry in the future.

The purpose of this study was to investigate the Digital Paradigm cords depicted on the Digital Clothing by borrowing nearby fields. Therefore, it will offer not only theoretical data but also databases for product development on functional and aesthetic views even though it is not systematically set up the idea vet. The Digital Paradigm cords of Interactivity. Nonlinearity and Combination in the Digital Clothing were determined. This study found that Interactivity Paradigm cord was expressed by the interaction of clothing and computer, the techniques of built in·attach·detach·fragment of the Digital Clothing at the external indicators, and maintained this personalizing that was pursued comprehension and the shape and silhouette of the existed clothing, that Nonlinearity Paradigm cord was able to overcome the limitation of a successively approach, in other words the discontinuous moving possibilities of time and space, that Combination Paradigm cord was contained creative concept without fixed ideas through coordination of Digital Clothing that was combination. continuous creation, changes and process between heterogeneous factors. In conclusion, introduction of the new Digital Paradigm is going to accelerate on lasting development and research.

The purpose of this paper is to study the initiatives on digital collection and development in engineering college libraries in the Rayalaseema Region of Andhra Pradesh. Eighty-one engineering college libraries in Rayalaseema Region have been surveyed to assess the initiatives taken on digital collection and development. This paper highlights opinions of librarians on most preferred digital materials and various digital resources acquainted with their library. The digital library initiatives cover a variety of activities starting from the digital collection building, digitization, digital collection, maintenance, and digital preservation. It is found that 34.57% of libraries are in the process of building digital collections, which is an encouraging trend among Engineering Educational Institutions in Rayalaseema Region.

We propose the hybrid control for the path control of wheeled mobile robot system. To develop the hybrid control of mobile robot, the continuous dynamics of mobile robot are modeled by the switched systems. The abstract model and digital automata for the path control are developed. This hybrid control system has the 3-layered hierachical structure : digital automata as the higher process, mobile robot system as the lower process, and the interface as the interaction process between the continuous dynamics and the discrete dynamics. The control of following the desired-paths with edges are investigated as the applications by the computer simulation.

Data mining is the process of autonomously extracting useful information or knowledge from large data stores or sets. For analyzing data of manufacturing processes obtained from database using data mining, source data should be collected form production process and transformed to appropriate form. To extract those data from database, a computer program should be made for each database. This paper presents a program to extract easily data form database in industry. The advantage of this program is that user can extract data from all types of database and database table and interface with Teamcenter Manufacturing.

Abstract In a conventional digital sector scan system in the ultrasound medical imaging, the sampling space is in the polar coordinates while the display space is in the cartesian coordinates, which necessitates a coordinate transformation process resultion process resulting the overall system very complex and bulky. In this paper we propose a new architecture of the Digital-Scan-Converter (DSC) for the ultrasound sector scan system in which sampling space is the same as the display space, so the data are displayed as they are acquired without any interpola- tion process required. To implement the above real time DSC. two frequency synthesizes with very high switching time and a low-pass filter are required. The former determines the precise location of the data points and the latter fills the gap betw- een pixels in the horizontal direction.

The effects of the MgO fabrication process on the properties of AC-PDPs were examined. MgO films were deposited by e-beam evaporation with various substrate temperatures and oxygen flow rates. MgO films were analyzed by XRD, CL and ellipsometer. Panel properties such as luminance, efficiency, discharge voltage and discharge delay time were measured with test panels. MgO films with higher temperature, smaller oxygen flow rate showed shorter discharge delay time. Also they showed smaller XRD peak intensity. These results revealed that the discharge delay time was strongly influenced by temperature and oxygen flow rate of the MgO fabrication process.

Topology optimization is widely accepted as a conceptual design tool for the product design. Since the resulted layout of the topology optimization is a kind of digital images represented by the density distribution, the seamless process is required to transform digital images to the CAD model for the practical use. In this paper, the general process to construct a CAD model is developed to apply for topology images based on elements. The node density and the morphology technique are adopted to extract boundary contour of the shape and remove the noise of images through erosion and dilation operation. The proposed method automatically generates point data sets of the geometric model. The process is integrated with Pro/Engineer, so that the engineer in practice can directly handle with curves or surfaces form digital images.
