  • The moment-curvature relation for simple bending is a well-studied subject and the classical moment-curvature diagram is commonly found in literature. The influence of axial forces has generally been considered as compression onto symmetrically reinforced cross-sections, thus strain at the reference fiber never has been an issue. However, when dealing with integral structures, which are usually statically indeterminate in different degrees, these concepts are not sufficient. Their horizontal elements are often completely restrained, which, under imposed deformations, leads to moderate compressive or tensile axial forces. The authors propose to analyze conventional beam cross-sections with moment-curvature diagrams considering asymmetrically reinforced cross-sections under combined influence of bending and moderate axial force. In addition a new diagram is introduced that expands the common moment-curvature relation onto the strain variation at the reference fiber. A parametric study presented in this article reveals the significant influence of selected cross-section parameters.

  • This paper proposed a new fast multi-reference frame motion estimation algorithm. The proposed algorithm reduces search areas of motion estimation using a linear relation of motion vector with distance of each reference frame. New algorithm executes full search area motion estimation in reference frame 0 and reference frame 1. After that, search areas in reference frame 2, reference frame 3 and reference frame 4 are minimized by distance of each reference frame and results of motion estimation in reference frame 0 and reference frame 1. The proposed algorithm does not use a threshold value which is obstacle of hardware implementation and processing time schedule. Also, it reduced computation quantity of multi-reference motion estimation. Hardware implementation of multi-reference frame motion estimation is possible by these features. Simulation results show that PSNR drop and bitrate increase of proposed algorithm are lower than those of previous fast multi-reference frame motion estimation algorithm The number of computation of new algorithm is reduced 52.5% and quality of result is negligible when compared with full search area motion estimation which has 5 reference frames.

  • Interpattern association (IPA) model which the interconnection weight matrix(IWM) is constructed by the association between patterns is effective in similar pattern recognitions. But, if the number of reference patterns is increased, the ability of recognition is decreased. Using a hierarchical recognition algorithm which adopts the tree search strategy, we classified reference patterns into sub-groups by similarity. In IPA model, if input includes random noise we make it converge to reference pattern by means of input includes random noise we make it converge to reference pattern by means of increasing the number of pixels of prohibited state in IWM. In relation to reference patterns the pixel of prohibited state made partially prohibited state of no connected state using which is not included common and feature regions by each reference patterns.

  • The recent situation on developments in an expanding field of reference and information service is reviewed through the cooperative arrangements and comprehensive planning among libraries in America. The growth of reference cooperation is examined first along with the social forces that influenced the library interdependence for service. Of the various interlibrary programs identified in relation to the cooperative reference work, interlibrary loan is viewed as the key to the use of library resources based on equal access and making use of the tools for information and research, therefore a reference principle. Several kinds of library systems specifically intended to improve the reference situation are identified and described in detail without any attempt to evaluate their performance in terms of unit size, cost, or quality of the service.

  • This study is intended to build a cross-reference system as syndetic device to provide bibliographic relations and to collocate variant access points through references, by developing a reference record format. To this end, the method of this study are as follows: First, the roles of references, which have long been used in traditional records, have been reviewed. Second, ways in which references are depicted not only by current cataloging rules but also by authority control systems are examined. Major characteristics of the reference record are summarized as fellows: 1) If variations either of an author name or of a title are made, or any related works are published, only a single reference record is created. This record uses existing authority records, and instead of adopting authority headings, it will expand the function of the explanatory reference as well as newly implementing a relational reference which can later be used as a reference record. 2) All the variations of identical personal or group names and of lilies are dealt as one access point. In place of current 'see' and 'see also' references, not drawing lines between authority heading(1XX field), 'see'(4XX field) and 'see also' reference(5XX field), all forms of names will be simply applied to record field '1XX'. 3) Any form of data elements, which are used as access points, will be described in '1XX' which has equal value. When a need arises to explain relationships between various access points, it can be met by applying the general explanation reference-name(666 field). Similarly, when there is a need to articulate bibliographic relationships between related works, they will be suggested through the title and relational reference. 4) The title and relational reference regulates related terms that each relation type contains its field, according to each relational type, by reclassifying entire fields in order to provide direct bibliographic relation types on reference records. 5) Pointers which are connected to each access point present reference control numbers.

  • Objective : We present reference values of flow velocities of intracranial and extracranial cerebral arteries and relation with change factor. Method : We checked transcranial Doppler ultrasonography on mean velocity, systolic velocity, pulsatility index, and resistance index of 252 patients. We also compared differences of change factor. Result : The result showed a difference by sex and age and relevance between vessels besides mean velocity of vessels related with past history and social history. Conclusion : According to the above results, females showed higher velocity of all vessels. With advancing age, subjects showed reduction in velocity and increase in pulsatility index and resistance index. Anterior cerebral, middle cerebral, and posterior cerebral artery increased in proportion to velocity of internal carotid artery and basilar artery. Vessel velocity correlated with diabetes mellitus, hypertension and hyperlipidemia.

  • In this paper, the ID-FDTD scheme, proposed in Reference [1] and [2], is modified and completely analyzed. The modifications are composed of three parts: rigorous stability analysis, dispersion relation for linear lossy media, and new scaling factors for permittivity, permeability, and conductivity. As a result, it is shown that the proposed scheme has lower dispersion error in spite of larger time step than the conventional standard scheme of Reference [3]. To validate the scheme, there are presented two scattering examples, which show excellent results.

  • There have been various cohesion measurements studied considering reference relation among attributes and methods in a class. Generally, these cohesion measurement are camed out in one class. If the range of reference relation considered are extended from one class to two classes, we could find out the reference relation between two classes. Tn this paper, we proposed a neural network to determine the method location. Neural network is effective to predict output value from input data not to be included in training and generalize after training input and output pattern repeatedly. Learning vector is generated with 30-dimensional input vector and one target binary values of method location in a constraint that there are two classes which have less than or equal to 5 attributes and methods The result of the proposed neural network is about 95% in cross-validation and 88% in testing.
