Design of an Interconnection Architecture and Sizing of Two (2) EPC Core Networks: The Case of Orange-Guinea

With the arrival of the 4G and 5G,the telecommunications networks have experienced a large expansion of these networks.That enabled the integration of many services and adequate flow,thus enabling the operators to respond to the growing demand of users.This rapid evolution has given the operators to adapt,their methods to the new technologies that increase.This complexity becomes more important,when these networks include several technologies to access different from the heterogeneous network like in the 4G network.The dimensional new challenges tell the application and the considerable increase in demand for services and the compatibility with existing networks,the management of mobility intercellular of users and it offers a better quality of services.Thus,the proposed solution to meet these new requirements is the sizing of the EPC(Evolved Packet Core)core network to support the 5G access network.For the case of Orange Guinea,this involves setting up an architecture for interconnecting the core networks of Sonfonia and Camayenne.The objectives of our work are of two orders:(1)to propose these solutions and recommendations for the heart network EPC sizing and the deployment to be adopted;(2)supply and architectural interconnection in the heart network EPC and an existing heart network.In our work,the model of traffic in communication that we use to calculate the traffic generated with each technology has link in the network of the heart.

The Value of Section Model Making in the Teaching of Architecture Major in Colleges and Universities

Section model making is an important part of teaching of architecture major in colleges and universities,which can train students’ comprehensive ability and professional quality,and make students meet the needs of the construction industry.In order to ensure the quality of section model making,it is necessary to collect and analyze the data in the early stage to ensure the smooth process of manual production.As far as the production process is concerned,it is necessary to do a good job in the early planning and control of the manual modeling,and pay attention to the coordination and cooperation of the group and the later inspection.

The Pedagogic Capacity of Architecture the Macro Project University Citadel—University of Atlántico Barranquilla—Colombia

Urban agenda nowadays puts pedestrians as the axis of urban design, and pedestrians are the most important thing in the city. The architect takes that idea and applies it in the project, and he focuses on prioritizing the pedestrian over the cars. Public spaces filled with green zones are a main element, water treatment is a design determinant, buildings use natural illumination as much as possible and culture and arts are reinforced through new scenarios.

The Central Axis of Beijing Described in Western Records

Many of the earliest Western adventurers to China elaborated in their writings about the symmetric structure of Beijing anchored on a central axis.KNOWN as a confluence of Eastern civilizations, ancient Beijing fascinated Europeans for its grand size and majestic buildings. At the core of the city is a 7.8-kilometer Central Axis that extends between the Drum Tower and Bell Tower in the north and the Yongding Gate in the south, along which stand many architectural icons that have been preserved to date.

Development of a “Space-Saving Model” for a One-Family Dwelling Case Study of Japanese Architecture with Space Limitations

The rapid globalization of building standards and codes in regards of contemporary housing and the growth of populations during this century demands an immediate response from designers in terms of space rationalizing to fulfill the forthcoming lack of architectural habitat on earth. The differences in culture imply a difference in the way of living, and the way of living indicates a contrast in the way of designing houses. A western house does not need an extra room covered with tatami mats for relaxation as a modern Japanese home would most likely do, as a separate living-like space. Organizations, among others, like CABO (Council of American Building Officials) and, in our specific case study, BCJ (Building Center of Japan) together with BRI (Building Research Institute) try to overcome these differences to provide better housing conditions to the world through the formulation of global designing and building standards. International publications like UBC (Uniform Building Code), IBC (International Building Code), OTFDC (One and Two Family Dwelling Code) and BSLJ (Building Standard Law of Japan) have also played an important role to globalize safety and design codes to better understand global housing under normal conditions. However, space limitations and concentration of human masses in mega cities result in a crucial new consideration: the urgent need of investigating the possibilities of rationally living within less space. Minimums provided by most codes do not take into account the space issue and overpopulation of large cities. Providing with some design recommendations for one-family dwellings has been the departure point and main motivation to carry out this case study based on actual buildings with the lack of space conditioning in a country where these conditions turn into reality.

Prolegomena for a Living Architecture

Rational and intuitive can be considered as two sides of the same coin? If they coexist in the design process,what do they refer to and what do they stand out for? What kind of relationship can be established between the act of prefiguring the work and of putting it into operation,according to procedures and techniques that are coherent and necessary for its construction? The value of an architectural project is shown by its being a continuous search for expression of art,even if,as we know,architecture also has a social function and plays a civil role.The universal meanings and the cultural reference context,which have always been the heritage of the architectural project,are increasingly taking on a secondary value.Issues and concepts such as:tradition,memory,modernity,invention and location seem to have lost any research prerogative at the expense of the meaning and use attributed to the architectural and urban composition in the overall design process.

Architectural Color of Streets in Cultural Quintessence Area of Dongjiaomin Lane in Beijing City

Based on the research on architectural color context in cultural quintessence area of Dongjiaomin Lane in Beijing City,the historical causes and changes of architectural color characteristics are explored.Through the investigation on the architectural color status of streets,GIS technology is used to construct architectural color information database for systematic study,and the typical characteristics,main laws and major problems of architectural color of streets are excavated.Combining social investigation and psychological evaluation,the public’s psychological judgment and demands on architectural color are mastered in a multi-dimensional way.Based on various conclusions,this paper explores scientific and effective methods for architectural color planning and coordination of streets,and puts forward specific suggestions for color protection planning,with a view to creating a architectural color pattern of streets in cultural quintessence area of Dongjiaomin Lane with overall harmony,perfect order,ancient and modern integration,and distinctive characteristics.
