We apply independent component analysis (ICA) for extracting an optimal basis to the problem of finding efficient features for representing speech signals of a given speaker The speech segments are assumed to be generated by a linear combination of the basis functions, thus the distribution of speech segments of a speaker is modeled by adapting the basis functions so that each source component is statistically independent. The learned basis functions are oriented and localized in both space and frequency, bearing a resemblance to Gabor wavelets. These features are speaker dependent characteristics and to assess their efficiency we performed speaker identification experiments and compared our results with the conventional Fourier-basis. Our results show that the proposed method is more efficient than the conventional Fourier-based features in that they can obtain a higher speaker identification rate.

This study is to examine and classify the phasic characteristics of organic thoughts in modern architecture. Organic architects have applied organic thoughts to solutions for the problems of each period in architecture since modern times. As results of this study, the architecture of organic thoughts from 1850s to 1940s could be divided into two phases. The phasic characteristics of the first phase from 1850s to 1910s was physical resemblance in real or fantastic appearance that the work of art and architecture should imitate organic forms from the view of solid empiricism. The phasic characteristics of the second phase from 1920s to 1940s was organic growth that the form appropriate to a work of art and architecture should grow from the nature of the problem itself as a system in nature grows from the view of pragmatism and was organic unity that the form and function or the form and content of a work of art should be inseparably integrated as the form in nature should grow out of the inner nature of the thing and be an expression of that inner nature from the view of expressive theory.

Tongdo temple is one of the representative temples that the Buddhistic outlook on the universe and the world is well expressed. This article will discuss the expressive and symbolic meaning that Darma talk on vulture peak signifies by contemplating the road leading from Ilju gate to Buddha's hall in terms of Karam arrangement of the temple and the unique plane delineation of Bulee gate. It seems that Darma talk on vulture peak is related to the reason why there is no Buddha statue in Buddha's hall and why the name of the mountain has been changed considering the resemblance of its shape to India's Youngchook mountain. The present study will take this relation into account and will show the religious faith and architectural meaning with respect to this relationship.

Image retrieval is a procedure to find images based on the resemblance between query image and all images. In retrieving images, the crucial step that arises is how to define the similarity between images. In this paper, we propose a new similarity measure which is based on distribution of color. We apply the new measure to retrieving two different types of images, wallpaper images and the logo of automobiles, and compare its performance to other existing similarity measures.

This paper presents on research findings of how Visual C++ program can be used to generate codes capable of performing ramjet engine simulation To understand the diversity and applicability of this tool an arbitrary ramjet model will be considered for which generated output values will be compared with those from a commercial program GASTURB 9 iterated under the same input parameters. Several governing thermodynamic equations will first be discussed in order that we understand the fundamental idea behind values printed out on the GUI. C++ compiler was chosen as a tool of use due to its availability, ease of use, ability to compute functions faster and uniquely possible to make a stand alone GUI executable in DOS mode. The program is developed in such a way that given the ambient flight conditions, burner exit temperature and several geometry areas the program generates its own input values used in the succeeding stations. A close resemblance of output values that define performance and thermodynamic state of the engine was realized between GASTURB 9 and using this code made from C++ compiler.

Vibrational spectroscopy has been applied to the benzenethiol molecule adsorbed on the silver surface. The results of infrared and Raman spectral studies have led to the conclusion that benzenethiol is chemisorbed dissociatively on the silver surface by rupture of S-H bond and the benzenethiolate formed upon adsorption is bound to silver via its sulfur atom. It seemed more likely that benzenethiol is adsorbed as being inclined to the silver surface. On contact with oxygen, the geometry of the adsorbed species appeared to bear a resemblance to that of silver benzenethiolate salt. The infrared bands of adsorbed species remained with little decrease of intensity even after the prolonged evacuation at 673 K, indicating that benzenethiol is very strongly chemisorbred to the silver surface.

The effects of longitudinal velocity dusty fluid flow in a weak magnetic field are investigated in this paper. An external uniform magnetic field parallel to the flow of dusty fluid influences the flow of dusty fluid. Besides that, the problem under investigation is completely defined in terms of identifying parameters such as longitudinal velocity (u), Hartmann number (M), dust particle interactions β, stock resistance γ, Reynolds number (Re) and magnetic Reynolds number (Rm). While using suitable transformations of resemblance, The governing partial differential equations are transformed into a system of ordinary differential equations. The Hankel Transformation is used to solve these equations numerically. The effects of representing parameters on the fluid phase and particle phase velocity flow are investigated in this analysis. The magnitude of the fluid particle is reduced significantly. The result indicates the magnitude of the particle reduced significantly. Although some of our numerical solutions agree with some of the available results in the literature review, other results differs because of the effect of the introduced magnetic field.

This paper presents extended state feedback control based on impulse response for lane change of autonomous driving vehicle. The triple characteristic root of path tracking system and longitudinal velocity determine feedback gains. We suggest a resemblance of impulse response curve of the system and lane change trajectory of the vehicle. The root affects the duration of lane change and lateral acceleration. The effect of limited lateral acceleration and saturation of steering angle will be analyzed and discussed. Finally, simulation results will show the trajectory of lane change based on impulse response under limitation of lateral acceleration.

Nakseonjae in Changdeokgung Palace was established at The King Hunjong's 13rd year (1847), the mid-19th century. It was constructed for own rests of King Hunjong and the residence of Kyungbin (king's concubines), and is showing features of upper-class houses from several points such as rustic architectural types by getting out of authoritative aspects as king's shelter space within the palace, block and floor distribution that separated spaces for men and women, simplicity in structures and styles, and non-colorful painting etc. This study aims at tracing on which architectural types did the upper-class houses within Hanyang (modern Seoul) at late Joseon Dynasty have and what was characteristics of Nakseonjae. The resemblance between Nakseonjae and the upper-class houses was very little differences from scale aspects, and floor plan shapes of Anchae (women's quarters) and Sarangchae (men's quarters) were followed basic common styles. Also, resemblance could be confirmed in the structural styles too. Characteristics of Nakseonjae are showing apparent differences from clearance compositions such as hall configuration etc. Nakseonjae was king's dwelling place, and spaces for house's collateral functions such as kitchen, stable, and warehouse etc together with shrine were unnecessary, and such places were substituted into servants' quarters for assisting the Royal family. In detailed structural styles, column's size was larger 3cm or more than the upper-class houses, and its height was higher to the degree of 30~60cm. Besides, formality as king's shelter space was raised more in decorating aspects, and Nakseonjae was implemented by getting architectural influences from Qing Dynasty of China. This study induced features of Hanyang's upper-class houses at the 19th century by supplementing distribution and space configurations at existing cases of Seoul and Gyeonggi area together with house diagrams having been collected by Gaokdohyung (site and floor plan) of Jangseogak Library, and confirmed resemblances and differences with Nakseonjae, that is, features of Nakseonjae. Through the result, this study judges a fact that architecture of Nakseonjae seemed to be affected from conveniences of upper-class houses within Hanseong, and also architectural styles and distribution types of Nakseonje would give influences to the upper-class houses.

본 논의의 출발점은 '자신을 본다'는 거울의 시선에 있다. 거울은 시각을 연장하고 자신이 가질 수 없는 상들을 제공하면서, 닮음, 재현, 반성, 실재 등에 대한 여러 의문을 제기하며 자의식을 강화하는 등 수세기 동안 그 의미는 재인식되어 왔다. 이처럼 거울을 본다는 것은 자기상의 또 다른 표면적 존재를 낳아, 거울 자체의 양면성이라는 실체와 허상 간의 모호한 간격으로 인해 지속적인 관심의 대상이다. 오늘날 거울의 반사상에 대한 과도한 열중은 더욱 심화되어 표출된다. 복잡한 이중적인 구조로 채워진 거울의 시선은 보는 자와 보이는 자의 관계로, 주체와 대상, 대상과 주체와의 불분명한 경계를 낳으며, 타인의 시선으로부터 존재하는 모든 국면들과 마주하며 교차적인 세계의 가능성을 열어준다. 더욱이 거울의 반사적 의미는 회화와 문학을 비롯한 여러 가지 미적 표현양식에 다양한 시선으로 떠오르는 모호한 수수께끼의 매체로서, 작가들에게 적지 않게 반영되며 창조적인 담론을 낳았다. 이에 본고에서는 거울의 시선이 세계의 상황 속에 서있는 이중의 영역에 반영된 불투명한 인간의 시선임을 제시하며, 보다 구체적인 접근을 위해 거울의 역사적 흐름을 전개하여 문학, 예술 작품에 투영된 일련의 사례들을 통해 닮음의 반사적 구조를 드러낼 것이다. 이 과정은 보는 자와 보이는 자의 관계, 즉 지각하는 주체와 거울에 반영된 타자의 시선임을 모색해봄으로써, 나와 세계가 상호 얽힘의 교차관계 속에서 자신의 삶이 존재하고 있음을 반추해보는 계기가 될 것이다.
