  • The HCCI combustion mode poses its own set of narrow engine operating by knocking. In order to solve this, inhomogeneity method of mixture and temperature is suggested. The purpose of this research is to get fundamental knowledge about the effect of thermal stratification on HCCI combustion of PRF -Air mixture. The temperature stratification is made by buoyancy effect in combustion chamber of RCM. The analysis items are pressure, temperature of in-cylinder gas and combustion duration. In addition, the structure of flames using the two dimensional chemiluminescence's images by a framing camera are analyzed. Under stratification, the LTR starting time and the HTR starting time are advanced than that of homogeneous. Further, the LTR period of homogeneous conditions became shorter than that of the stratified conditions. With the case of homogeneous condition, the luminosity duration becomes shorter than the case of stratified condition. Additionally, under stratified condition, the brightest luminosity intensity is delayed longer than at homogeneous condition.

  • This article assesses the recent development of libraries in Myanmar and efforts to build the sector's capacity leading up to and after the first democratic elections held in the country in nearly 50 years, at the end of 2015. Cyclone Nargis in 2008 is viewed as a 'framing event' (Birkland, 1998) that led to national legal and policy reforms, an increase in national and international projects to support development of Myanmar libraries, and the strengthening of local actors including the Myanmar Library Association to coordinate and lead development activities. Although in need of modernisation, networking, and professional skills, the existence of a widespread number of all library types across the country provides an important foundation for further development. The current status and readiness of libraries is explored in the broader context of the rapid leap from limited to more widely available access to information and technology. The article finds that there is great potential for libraries in Myanmar to support the continued transition to democracy as evidenced by the role of libraries and access to information in other countries that have transitioned. Remaining challenges include the potential of backsliding on national reforms, and the need for significant investments in infrastructure and skills. Libraries must be transformed to meet the changing needs of information users in a young democracy.

  • This paper analyzes two films on the theme of love, and , which were released in 2002 and 2015 respectively, directed by Tod Haynes. Both movies have similar narratives of obstacles and overcoming of love, and deal with love that is not accepted by society. Two films conclude differently under similar situations, where the author's change can be observed. The purpose of this study is to examine the author's arguments and the process of change through comparison with the original novels and image expression method used in the films, especially focusing on the variations of characters in the original novels and Mise-en-scene and framing methods that visually depict the obstacles to the mind and love of lovers.

  • The main aim of the study is to test a house pricing model by combining hedonic and asset-based pricing models. An understanding of the relationship between house pricing and its return (the rental income) helps to establish houses as a significant asset class. The model tested the relationship between house pricing (dependent variable) and the house attributes (independent variables) derived from Freeman's framework of housing attributes. This study uses a large data-set of 1,899 sample of new, high-end houses purchased between 2016 and 2019 collected from the national capital region of India (Delhi-NCR). The algorithm was built in R-Script, and stepwise multiple linear regression was used to analyze the model. The analysis of the model proves that the three significant variables, namely, carpet area, pay-off, and annual maintenance charges explain the price function. Further, the model is statistically fit. The major contribution of the study is to understand the key factors and their influence on the house pricing. The model will be helpful in risk assessment in the housing investment and enhance the chances of investment. Policy-makers can use information about the underlying valuation drivers of the house prices to stabilize the market and also in framing the tax policies.

  • The use of light steel framing as a method of house construction has increased significantly throughout Japan, United States and Europe. Industrialized unit method are prevailing in developed countries. Unit modular house industry has supported an intensive technical development, and housing systems are now available, which are highly adaptable in form and use. Unit modular house have their own merits and demerits, but the more crucial aspect is that the constant design standard should be applied in each design procedure. It entails the necessity of industrial housing development on the open system basis. This paper describes the general forms of factory product system of unit modular housing system in Korea, United States, Japan. And this study attempts to propose the unit factory product system of which the rate of pre-fabrication is the biggest, that can cope with the demand of user on the basis of open-system.

  • After the large destruction of Lisbon due to the 1755 earthquake, the city had to be almost completely rebuilt. In this context, an innovative structural solution was implemented in new buildings, comprising internal timber framed walls which, together with the floors timber elements, constituted a 3-D framing system, known as "cage", providing resistance and deformation capacity for seismic loading. The internal timber framed masonry walls, in elevated floors, are constituted by a timber frame with vertical and horizontal elements, braced with diagonal elements, known as Saint Andrew's crosses, with masonry infill. This paper describes an experimental campaign to assess the in-plane cyclic behaviour of those so called "frontal" walls. A total series of 4 tests were conducted in 4 real size walls. Two models consist of the simple timber frames without masonry infill, and the other two specimens have identical timber frames but present masonry infill. Experimental characterization of the in-plane behaviour was carried out by static cyclic shear testing with controlled displacements. The loading protocol used was the CUREE for ordinary ground motions. The hysteretic behaviour main parameters of such walls subjected to cyclic loading were computed namely the initial stiffness, ductility and energy dissipation capacity.

  • A pilot study has been conducted to guide the development of a finite element modeling formulation for the analysis of architectural glass curtain walls under in-plane lateral load simulating earthquake effects. This pilot study is one aspect of ongoing efforts to develop a general prediction model for glass cracking and glass fallout for architectural glass storefront and curtain wall systems during seismic loading. For this study, the ANSYS finite element analysis program was used to develop a model and obtain the stress distribution within an architectural glass panel after presumed seismic movements cause glass-to-frame contact. The analysis was limited to static loading of a dry-glazed glass curtain wall panel. A mock-up of the glass curtain wall considered in the analysis with strain gages mounted at select locations on the glass and the aluminum framing was subjected to static loading. A comparison is made between the finite element analysis predicted strain and the experimentally measured strain at each strain gage location.

  • In current ductility-based earthquake-resistant design, the estimation of design forces continues to be carried out with the application of response modification factors on elastic design spectra. It is well-known that the response modification factor (R) takes into account the force reduction, strength, redundancy, and damping of structural systems. The key components of the response modification factor (R) are force reduction ($R_{\mu}$) and strength ($R_S$) factors. However, the response modification and strength factors for structural systems presented in design codes were based on professional judgment and experiences. A numerical study has been accomplished to evaluate force reduction, strength, and response modification factors for special steel moment resisting frames. A total of 72 prototype steel frames were designed based on the recommendations given in the AISC Seismic Provisions and UBC Codes. Number of stories, soil profiles, seismic zone factors, framing systems, and failure mechanisms were considered as the design parameters that influence the response. The effects of the design parameters on force reduction ($R_{\mu}$), strength ($R_S$), and response modification (R) factors were studied. Based on the analysis results, these factors for special steel moment resisting frames are evaluated.

  • People live in an environment which affects the human b by way of ‘Affordance’ .. And the interaction between h human and the surrounding environment arises ‘the sense of place' through adoptation. Considering the human emo¬t tional and psychological needs, besides the functionalones, for the design of environment gives ‘the place’ the h humanized atmosphere. Then the viewing-window, re¬f fleeting the dweller’s sensibility and aesthetic aspect, be¬c comes an important design element for the human interi¬o or atmosphere. G Generally, the view has the character of the Panorama a and sometimes of the Picture. And the viewing - window t transfigures the visual effects by ways of ‘Framing’, at t taching the ’Screen’ and ‘Successive development' of the views through openings on the wall. Hence this study w was developed from the aesthethic view-points of archi t tecture, cinema, picture and photography etc., and the c conclusions are as follows. T The ‘Frame’ limits the boundary of the view into a p particular area, while the ‘Screen’ changes the clear view t to an obscure one. And the wall-openings located with i intervals show the fragments of the outer view in a suc¬c cessive way. And these techniques applied to the viewing window make the viewer have the associated meanings d derived from the ‘Guided Projection'. So, the associative p psychology of the viewer complements the partiality, ob¬s scurity and brokenness of the view into a complete one, a and finally the view comes to be an aesthetic one to the v vIewer.
