Superyachts are passenger vessels whose hull exceeds 24m. They are a kind of luxurious leisure ships. Interior designers can contribute in the field of space design of superyachts. This study is intended to investigate the space elements and their organization of superyachts for putting the base of superyachts interior design. Especially it is focused on the interior space division by structural elements such as the watertight bulkheads and decks. In this study we analyze general arrangements, floor plans of decks, of 31 superyachts and extract space elements and their disposition in three dimension. On the basis of the space arrangement we classify the types of space organization of superyachts. And then we inquire the interior space division of superyachts, which is characterized by the structural elements of the ship. The watertight compartments made by the bulkheads and decks have a great effect on interior space design in super yachts. The results of this study are summed up as follows: At first, the small-size superyacht has 3 decks and the midium or large-size superyachts has 4decks. Secondly, depending on the number of decks the superyachts has several typical patterns of space organization. Thirdly, in general there are 5-6 watertight compartments on a deck depending on the superyachts scale. Finally, there are distinct separation between the passenger's movement and the crew's movement on the ship.

In this letter, we investigate the spectral efficiency of IEEE 802.22 wireless regional area network (WRAN) spectrum overlay when it is used in TV white space. Since 2004, when the FCC published the notice of proposed rule making 04-186 to make use of unused TV spectrum, the IEEE 802.22 working group has been standardizing specifications for WRAN operations. There have been a few papers investigating the spectral efficiency of this, but their analyses were limited to the cases for various guard distances between WRAN base stations. Since WRAN base station (BS) power for WRAN service may differ from country to country, it is important to analyze the spectral efficiency for various WRAN BS powers. In this letter, we analyze the spectral efficiency of WRAN spectrum overlay as a function of the power of WRAN BSs. The simulation results show that spectral efficiency decreases as the power of WRAN BSs and guard distances increase.

The integration of PV modules into building facades or roof could raise their temperature that results in the reduction of PV system's electrical power generation. Hot air can be extracted from the space between PV modules and building envelope, and used for heating in buildings. The extraction of hot air from the space will enhance the performance of BIPV systems. The solar collector utilizing these two aspects is called PV/T(photovoltaic/thermal) solar collector. This paper compares the experimental performance of two different types of air type PV/T collector units: the base case of a collector unit with 10cm gap for forced ventilation and the other unit with copper pin attached to PV module to enhance its thermal performance. The experimental results shows that the base case unit had the overall efficiency of 41.9% and the improved unit with copper pin attached to PV module had 50.1% efficiency. For these air type PV/T units, the forced ventilation of the air space improved the electrical performance as well as the thermal performance.

This study examines the space composition and character of Elizabethan Theater base on the theory of drama and Shakespeares play in the english traditional theater. Contemporary multi purpose theater and public space is considered as a symbolic representation of the Elizabethan theaters organization and renaissance culture. In the historical theory, the Shakespeares theater was a common tool and best systeme in reflecting peoples lives. This role of theater as mass culture and new style of theater permanent design has get its value with the population increase and the urban centralization of the city and urban common sense. This study attempts to reevaluate the need of public space in modern society through a critical review of theater and its use as a open space design. Content analysis was used to discuss the topics of this study including the historical background of the theater, the relationship between Greek culture and modern design, and the role of scenery, auditorium and its impact on urban environment. The scope of the study is limited to the comparison of Elizabethan theater and space use program from the space critic and sociologist. Today the concept of theatrical space is altered with the advent of non-objects and multi media space. This study provides insights for the future implications of theatrical space in developing public space for its a new definition as cultural representation.

This study was to analyze the displacement and the magnitude and mode of distribution of the stresses in the lower overdenture, the mucous membrane, the abutment teeth and the mandibular supporting bone when various abutment designs were subjected to different loading schemes. For this study, the two-dimensional finite element method was used. The models of overdenture and mandibe with the canine and the second premolar remaining, were fabricated. In the first design, a 1 mm space was prepared between the denture and the dome abutment with the height of 2 mm(OS). In the second design, a contact between the denture and the occlusal third of the dome abutment with the hight of 2 mm was prepared(OC). In the third design, a 0.5 mm space was prepared between the denture and 8 degree tapered cylindrical abutments with the height of 7 mm(TS). In the fourth design, a contact between the denture and the occlusal two thirds of the conical abutments with the height of 7 mm was prepared(TC). In order to represent the same physiological condition as the fixed areas of the mandible under loading schemes, the eight nodes which lie at the mandibular angle, the coronoid process and the mandibular condyle were assumed to be fixed. Each model was loaded with a magnitude of 10 Kgs on the first molar region (P1) and 7 Kgs on the central incisor region (P2) in a vertical direction. The force of 10 Kgs was then applied distributively from the first premolar to the second molar of each motel in a vertical direction (P3). The results were as follows: 1. The vertical load on the central incisor region(P2) produced the higher displacement and stress concentration than that on the posterior region(P1, P3). 2. The case of space between abutment and denture base produced higher displacement than that of contact, and the case of long abutment produced higher displacement than that of short abutment because of low rigidity of denture base. 3. The magnitude of the torque and vertical force to the abutment teeth and the stress distribution to the denture base was higher in the telescope coping than in the overdenture coping. 4. The vertical load on the central incisor region(P2) produced higher equivalent stress in the mandible than that on the posterior region(P1, P3). 5. The case of space between abutment and denture base produced better stress distribution to the farther abutment from the loading point than that of contact. 6. In case of sound abutment teeth, the type of telescope coping can be used, hilt in case of weak abutment, the type of overdenture coping is considered to be favorable generally.

In this paper we describe the method which optimizes the partition of the input space by means of measure of fuzziness for fuzzy neural network. It covers its generation of fuzzy rules for input sub space. It verifies the performance of the system depended on the various time interval of the input. This method divides the input space into several fuzzy regions and assigns a degree of each of the generated rules for the partitioned subspaces from the given data using the Shannon function and fuzzy entropy function generating the optimal knowledge base without the irrelevant rules. In this scheme the basic idea of the fuzzy neural network is to realize the fuzzy rule base and the process of reasoning by neural network and to make the corresponding parameters of the fuzzy control rules be adapted by the steepest descent algorithm. According to the input interval the proposed inference procedure proves that the fast convergence of root mean square error (RMSE) owes to the optimal partition of the input space
