In this paper, we describe a unique self oscillating and mixing (SOM) down-converter design using a modified defected ground structure (DGS). The proposed SOM converter is consisted of self-oscillator, which can produce negative resistance and select resonance frequency, RF matching circuit, and IF low pass filter. As the advantage of this SOM converter can mix LO and RF signals as well as inducing LO signal with only one active device. it is designed as a simple structure and the low cost. Also, there is easy advantage to be applied in RFIC/MMIC technology because it offers excellent phase noise performance in spite of using micro-strip structure. The LO signal for the proposed SOM converter is designed at 1㎓ and RF frequency was chosen to be 800MHz. The achieved conversion loss and phase noise performances of the implemented SOM converter are 15㏈ and -95dBc/Hz at 100KHz offset frequency respectively. The equivalent circuit parameters for DGS are extracted by using a three dimensional EM simulator and simple circuit analysis method.

Here we describe a unique self-oscillating mixer (SOM) design using a modified defected ground structure (DGS) for down-converter. Proposed SOM is consisted of self-oscillator, which can produce negative resistance and select resonance frequency, and input/output matching filter. As the advantage of this SOM can be reused by module that mix signals with transistor that is used to oscillator, it is simply and low-costly designed Also, there is easy advantage to be applied in RFIC/ MMIC technology because it offers excellent high Q value in spite of using micro-strip structure. Designed self-oscillating frequency is 1.04GHz and RF frequency established is 0.8GHz. It was achieved 20dB conversion loss and phase noise of -95dBc/Hz at 100KHz offset frequency over intermediate frequency (IF). The equivalent circuit parameters for DGS are extracted by using a three dimensional EM simulator and simple circuit analysis method.

This paper reports on punching shear behavior of reinforced concrete panels, investigated experimentally and through finite element simulation. The aim of the study was to examine the punching shear of high strength concrete panels incorporating different types of aggregate and silica fume, in order to assess the validity of the existing code models with respect to the role of compressive and tensile strength of high strength concrete. The variables in concrete mix design include three types of coarse aggregates and three water-cementitious ratios, and ten-percent replacement of silica fume. The experimental results were compared with the results produced by empirical prediction equations of a number of widely used codes of practice. The prediction of the punching shear capacity of high strength concrete using the equations listed in this study, pointed to a potential unsafe design in some of them. This may be a reflection of the overestimation of the contribution of compressive strength and the negligence of the role of flexural reinforcement. The overall findings clearly indicated that the extrapolation of the relationships that were developed for normal strength concrete are not valid for high strength concrete within the scope of this study and that finite element simulation can provide a better alternative to empirical code Equations.

Concrete mix design is used as essential data for the quality of concrete, analysis of structures, and stable use of sustainable structures. However, since most of the formulation design is established based on the experience of experts, there is a lack of data to base it on. are suffering Accordingly, in this study, the purpose of this study is to build a predictive model to use the concrete mixing factor as basic data for calculation using the DNN technique. As for the data set for DNN model learning, OPC and ternary concrete data were collected according to the presence or absence of admixture, respectively, and the model was separated for OPC and ternary concrete, and training was carried out. In addition, by varying the number of hidden layers of the DNN model, the prediction performance was evaluated according to the model structure. The higher the number of hidden layers in the model, the higher the predictive performance for the prediction of the mixing elements except for the compressive strength factor set as the output value, and the ternary concrete model showed higher performance than the OPC. This is expected because the data set used when training the model also affected the training.

This research analyzed the expression trend about the slit which composes the open space by the visual concept and then introduced the imbedded aesthetic value in it. Based on it, this work aims at showing the evidence on the slit as a utilizing tool for various design applications and providing the basic materials in order to develop the creative design production in the fashion area in the future. Specifically, for the theoretical background in this research, the concept of slit and its chronological changes were reviewed through literature. For the empirical analysis on the slit, a total of 226 designs with its application were analyzed from collection pieces in the four major collections including Paris, Milan, New York, and London from 2006S/S to 2012S/S. As a result of analysis, types of slit appeared as a slash, opening, slit, or a mix of them. These were applied to many different items of clothing, and among which, one-piece or dress was adopted most for application. In regard to space form, perpendicularity was used most frequently. But other various forms like cross and geometrical pattern were also used as well as curve, oblique line and horizontality. As to the arrangement of slit, single type was most frequently used. However, in addition to it, other types were also applied, producing both the functionality and the decorative detail such as bilateral symmetry, free irregularity, and a combination of regular and repeated layout which makes an effect of single pattern. Aesthetic values imbedded in slit were revealed as functionality, sensuality, spatiality, and decorativeness.
