ABSTRACT

The incorporation of acoustic comfort and strategies into public library design is discussed in this paper. For decades, one of the main goals of acoustic theory and experiments has been to solve architectural acoustic issues. Recent contributions by the soundscape approach have highlighted wider beneficial goals that acoustic designers can follow, such as encouraging ecological reasoning about the acoustic system and its understanding as a whole. Using references from the literature, this paper illustrates the application of architectural acoustics and soundscape methods into the field of architectural architecture education, stressing the importance of unique design circumstances and aural teaching strategies in learning contexts. According to the findings of this study, the incorporation of Acoustic comfort can be accomplished by architectural design rather than active means, and the literature review discusses all methods of achieving Acoustic comfort or Architectural Acoustics. This research would look at potential noise sources as well as steps or technology that can be incorporated into the architectural design of a public library to improve acoustic comfort. HVAC, atmospheric noise from outside the lecture room, low sound insulation construction materials, and so on are examples of noise sources.

Keywords: Acoustic design, soundscape, architectural acoustics, education, acoustic comfort.

ABSTRACT

A library is a well-planned facility where information’s are curated collection from a source or similar resources, selected by experts and are made accessible to a defined community for reference or borrowing is of high importance. A library that is designed with keen consideration on proper spatial organization and relationship to optimize efficiency and ensure it is a digitally considered space. Library should no longer be confined places  but should adopt and open spatial plan that will allow interaction between scholars this why including  learning commons are necessary, in line with this, emphasis on design methods that will allow for purpose is highlighted here. The functionality of the library space and how this space relate is dependent on how functional and the spaces flow into themselves. Principles and guidelines in achieving this paper carefully examined.  This paper therefore seeks to emphasize principles that should be adhered, to ensure the optimization of space and how they relate to themselves through the review of studies and related articles.

Keywords: Library, Spatial Organization, Optimal Efficiency, Learning Common.

ABSTRACT

In order to respond to the harsh environmental challenges, buildings are evolving to adapt to meet the needs of the people without harming the environment within its context. This research considers the Muttrah fish market project located in Muscat city, Oman and how it successfully implemented sustainability principles into its design process and construction. Several traditional markets in Oman experienced a great competition from the entrants of modern markets. The traditional markets failed to compete because of poor planning, inconvenient access, overcrowded trading activities, lack of air circulation and poor sanitation, affecting thousands of vendors. The former local market of Muttrah needed a new design to upgrade its commercial operations, in response to this, a more sustainable development model for Oman’s traditional markets is proposed based on sustainability and hopefully could become an example of traditional market revitalization in Oman.

DETERMINATION OF SCHWARZSCHILD’S RADIUS OF SOME PLANETARY BODIES IN THE SOLAR SYSTEM USING NEWTONIAN MECHANICS

ABSTRACT

The need to understand black hole formation, property and absorption of other celestial bodies is an interesting issue in Astrophysics and Astronomy. In this short article we avoided complex mathematical difficulty to obtain Schwarzschild’s radius of some planetary bodies, and this radius was computed using Newtonian expression for escape velocity. Results obtained shows that among the planets Jupiter requires a very large amount of gravitational pull to reduce to black hole and was found to be exactly the same with that using Schwarzschild’s metric.

Keywords and phrases: Black hole, Schwarzschild’s radius, Newtonian expression, escape velocity
