Purpose: This review focuses on the major 3-D image reconstruction techniques and their applications in plant and animal morphological analysis. Methods & Results: This paper begins with an overview of major 3-D image reconstruction techniques and their basic principles. Subsequently, their applications in plant and animal morphological analysis are reviewed. A discussion on the limitations and future research direction of 3-D imaging techniques for accurate, fast measurements and modeling of plant and animal morphological analysis follows. Conclusions: Owing to the increasing demand for plant and animal morphological analysis, the application of 3-D imaging techniques will increase in popularity among researchers and the agricultural industry.

This paper investigates several existing techniques to reduce high-availability seamless redundancy (HSR) traffic. HSR is a redundancy protocol for Ethernet networks that provides duplicated frames for separate physical paths with zero recovery time. This feature makes it very useful for real-time and mission-critical applications, such as military applications and substation automation systems. However, the major drawback of HSR is that it generates too much unnecessary redundant traffic in HSR networks. This drawback degrades network performance and may cause congestion and delay. Several HSR traffic reduction techniques have been proposed to reduce the redundant traffic in HSR networks, resulting in the improvement of network performance. In this paper, we provide an overview of these HSR traffic reduction techniques in the literature. The operational principles, advantages, and disadvantages of these techniques are investigated and summarized. We also provide a traffic performance comparison of these HSR traffic reduction techniques.

The application of LCC-techniques is being introduced at the on-going procurement programs of various techniques. LCC-techniques have the common characteristic that all are designed to motivate contractors to design, manufacture and deliver equipment with lower life cycle costs. You may believe that savings may be in the acquisition cost component of life cycle costs. However, primary emphasis is generally on reducing and controlling operating and support costs by transferring more responsibility to the contractor for equipment operating and support cost performance. It has been found that life cycle cost procurement provisions must be individually tailored to each program. In this study, the currently identified LCC procurement techniques including a variety of LCC incentive provisions are introduced. Moreover, verification method, a procedural issue and incentive to application of LCC-techniques are examined.

In modern society as people adapt to social and cultural changes, people prefer high-scarcity designed products rather than standardized ones. Consequently, this adaptation lays a foundation in art and cultural domains to express uniqueness and individuality. The purpose of this study is to develop fashion designs by fusing fashion painting and handicraft techniques through creative and various artistic expressions. The researchers studied the sociocultural background of modern handicraft fashion using document-based research methods. Based on the characteristics of modern handicraft, we produced six garments that applied fashion painting techniques. In this study, the origin of fashion painting was found in ornaments such as tattoo or body-painting. We determined that modern designers were using various fashion painting techniques and motives as unique and advanced ornamentary skills. Harmonizing various handicraft techniques(dyeing, embroidery, quilt, patchwork, beads, fashion painting, etc.) centered on fashion painting enabled creation of unique fashion design through varieties of artistic expressions.

This paper reviews dynamic programming (DP), surveys approximate solution methods for it, and considers their applicability to process control problems. Reinforcement Learning (RL) and Neuro-Dynamic Programming (NDP), which can be viewed as approximate DP techniques, are already established techniques for solving difficult multi-stage decision problems in the fields of operations research, computer science, and robotics. Owing to the significant disparity of problem formulations and objective, however, the algorithms and techniques available from these fields are not directly applicable to process control problems, and reformulations based on accurate understanding of these techniques are needed. We categorize the currently available approximate solution techniques fur dynamic programming and identify those most suitable for process control problems. Several open issues are also identified and discussed.

Autoregressed Controller, which have trend algorithm, seeks to minimize variability by transferring the output variable to the related process input variable, while multivariate process control techniques seek to reduce variability by detecting and eliminating assignable causes of variation. In the case of process control, a very reasonable objective is to try to minimize the variance of the output deviations from the target or set point. We also investigate algorithm with relevant Shewhart chart, Theoretical control charts, precontrol and process capability. To help the people who want to make the theoretical system, we compare the main techniques in "a study on the relation between multivariate process control techniques and trend algorithms".

Current techniques of residential planning are based upon planning theories and experiences which have evolved over time. These techniques are prerequisite conditions in establishing a firm foundation upon which residential sites can be developed. Residential planning techniques, which have been introduced to Korea from such areas as Western Europe, North America and Japan, have been changing as a result of attempt to properly acculturate these foreign influences into a traditional, yet rapidly progressing Korean society. It has been this objective of Korean planners, of considering domestic conditions while incorporating planning experiences of other countries, that has spearheaded Korea's phenomenal development in recent times. In this study, the changes and perspectives of residential planning concepts are examined from a historically comparative point of view. This approach allows for a macroscopic perspective on the various theories of residential planning which are constantly changing.

Edges are one of the most important features used in various computer vision applications. Most of the known edge detection techniques are categorized into three gropus: First two approaches are to find gray level changes using first-order or second-order differentiation. The third method uses intrinsic propoeties of edges such as the result shown during scale space filtering. In this paper, we study various kind of edge detection techniques. Two images (Lenna image and a certain image which is composed of step, ramp, roof, and other artificial edge patterns) are used to compare different edge detection techniques and to verify the advantages and disadvantage of each techniques.

A lot of PSC railway bridges have been constructed in countries and, they are considered as cost-effective and less maintenance-demanded structures. However, recently several collapse of PSC bridges happened in Europe show that PSC bridges have some serious maintenance problems related to tendon corrosion and wire fractures. Furthermore, any reliable NDT method is not presented until recently. In this paper, AE techniques are investigated for detection of wire fractures in PSC beam. Using long-term monitoring AE techniques, two acoustic signals of wire fractures in a PSC beam are obtained. These data are compared to other noise signals. Based on the test results, the characteristics of the AE signals are classified and wire fracture signals are figured out among the other AE signals. As a result, AE techniques are certainly exposed to tendon fracture sound, and application of AE techniques are better than any other non-destructive method.

This study was performed to report the effectiveness of oriental medical treatment and muscle energy techniques on a patient with piriformis syndrome. The patient was diagnosed as piriformis syndrome and treated with acupuncture, herb medicine, physical therapy and muscle energy techniques. We have evaluated curative efficacy with measuring changes of visual analogue scale and physical examination according to period of hospitalization. After treatment, pain and visual analogue scale decreased. Physical examinations were recuperated nearly to normal findings and ambulation was improved. These results suggest that oriental medical treatment and muscle energy techniques were effective on patient with piriformis syndrome.
