This paper describes the formulation for the analysis of the free vibration of cylindrical shell panels with elastic supports by the transfer influence coefficient method. This method was developed on the base of the concept of the successive transmission of dynamic influence coefficients. The analysis algorithm for cylindrical shell elastically restrained by springs, which plays an important role in many industrial fields, is discussed. The supporting springs have the axial, circumferential, radial and rotational spring constants uniformly distributed along the circumference of the shell. The simple computational results on a personal computer demonstrate the validity of the present method, that is, the numerical high accuracy analysis method and the flexibility for programming, compared with results of the transfer matrix method. We also confirmed that the present algorithm could obtain the solutions of high accuracy for system with a number of intermediate rigid supports. And we could easily treat the intermediate support and all boundary conditions by adequately varying the values of spring constants.

The analysis algorithm for thick urved plates is discussed as they are extensively used in many industrial fields such in marine, nuclear and aerospace structures. The equations of vibration of a cylindrically thick curved plate based on the Herrmann Mirsky theory are written a coupled set of first order differential equations. By introducing the transfer matrix of the curved plates in the circumferential direction, these equations are written in a matrix differential equation. The supporting springs have the axial, circumferential, radial and two rotational spring constants uniformly distributed along the axis of the curved plates. The natural frequencies are calculated numerically up to higher modes for simple computational models. We also investigated the dynamic characteristics of various of type of vibration arising in the curved plates quantitatively.

A 1-year old, intact male Jin-do dog with ataxia, hypersalivation and anorexia was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. Ivermectin toxicosis was diagnosed by the history taking, clinical signs, physical examination and neurological examination. After therapy with intravenous fluid and lipid emulsion administration, the clinical signs were found to have significantly improved.

In this study, a methodology of synchronous control which can be applied to position synchronization of a two-axes rotating system is developed. Based on coupling structure, the synchronous control system is composed of disturbance observer, speed and synchronous controllers. The speed controller is designed to follow speed reference. And the disturbance observer is designed to restrain synchronous error generated by torque disturbance. In addition, the synchronous controller is designed for a viewpoint of accurate synchronization. The effectiveness of the proposed method is verified through various simulation

This paper describes the formulation for the analysis of the flexural free vibration of rectangular plate structure with elastic supports and stiffeners by the transfer influence coefficient method. This method was developed on the base of the concept of the successive transmission of dynamic influence coefficients. Rectangular plate are simply supported at two opposite sides, and it has the stiffeners and distributing springs over node line normal to two simply supported edge. The validity of the present method is demonstrated through simple numerical example, and is also compared with results of the transfer matrix method on a personal computer. And all boundary conditions and the intermediate stiff can be treated only by adequately controlling the values of spring constants.

<P>Solution‐processable reduced graphene oxide as a hole‐transporting layer for highly efficient and stable organic solar cells is reported on page 4923 by Dong‐Yu Kim, Seok‐In Na, and co‐workers. Introduction of a newly reduced graphene oxide by simple solution processing into solar cells dramatically raises the cell efficiency and cell life‐time. The results will allow full use of chemically reduced graphene and will advance the realization of carbon‐based printable optoelectronic devices. </P>

This study Focuses on developing several modules involved in an integrated production information system for medium- or small-sized industries. The modules of order management, quality control, production scheduling, and shop management are executed for an example case industry. The potential values of this research includes that the major information modules to collect, analysis, and display production data and shop data for constructing the computer integrated manufacturing system(CIMS) are programmed with various features of medium- or small-sized industries
