Abstract

Imageability is the quality of a place that makes it distinct, recognizable, and memorable. It defines the character and identity for cities. However, the fast expansion of urban development affects the image of city and its fabric toward the mega scale and transforms cities local cultural life as loosing most of their historic fabrics. These make cities loose there images gradually. Hence, the aim of this paper is to explore the main physical elements that contribute toward attractiveness as one of imageability character in Salt City in Jordan. Historical review and site analysis were the main methodology used in this study. This paper show some of the physical elements that contribute to attractiveness connected with image of the Salt City in Jordan, these elements are: building appearance (material, façade design) and landscape (topography).

Abstract

Rapid development has affected the elements of urban spaces adversely, particularly streets. These changes produce faceless cities with high dependency on vehicles for transportation to key ‘consumers’ aside from buildings that are not designed for the local environment and local needs. In urban design, concerns on character affect the sense of place. Thus, this paper assesses the crucial element of streets with respect to design and character in the urban setting, the subsequent issues, and the recommended solution. This study focuses on the scenarios that threaten today's street design. This work will discuss the advantages of traditional streets, which could be a potential solution to the issues mentioned earlier. Finally, a street design based on the traditional street model is proposed to fulfill the criteria necessitated by the local community.

Abstract

In Hungary a lot of people live in condominiums or in block of flats where fire often occurs despite of precise design and effective fire protection arrangements. This means a hazard for the people living there, for the building constructions and also for the environment. A deeper knowledge of the burning process and examining the negative effects of fire load on building constructions with scientific methods are actual questions nowadays. In order to get to know the phenomena more accurately, fire spread in a bedroom was modeled and numerical simulation was carried out, which is presented in this paper in detail. These experiences may help increasing the fire safety and preventing fires in apartments. The simulations were carried out considering the characteristics of the Hungarian architecture.

Abstract

In order to develop the quality of urban spaces, street furniture seems to be the significant element that defines the city’s social attraction points. It stimulates outdoor spaces because of its location, buildings and sidewalk meet. This study explores the issues of design criteria that introduce sustainability into street furniture design in urban public space in Tunisia. This research is based on the role of street furniture and its importance in urban public spaces, and the possibility of supplementing a recycling design. This paper aims to explore the necessary criteria to design sustainable street furniture in order to present its importance in a way that helps to ameliorate the quality of living in urban areas and cities.

Abstract

In watershed modeling research, it is practical to subdivide a watershed into smaller units or sub-watersheds for modeling purposes. The ability of a model to simulate the watershed system depends on how well watershed processes are represented by the model and how well the watershed system is described by model input. This study is conducted to evaluate the impact of watershed subdivision and different weather input datasets on streamflow simulations using the soil and water assessment tool model. For this purpose, Cuhai-Bakonyér watershed was chosen as a study area. Two climate databases and four subdivision variations levels were evaluated. The model streamflow predictions slightly effected by subdivision impact. The climate datasets showed significant differences in streamflow predictions.

Abstract

With the development of economic globalization and the information age, architecture has gradually become a kind of seal of politics, capital and culture, and is divorced from the spirit and life experience of the existing places in the region. Therefore, the field of architecture constantly seeks new research paradigm from the interdisciplinary perspective and reconsiders the creative activities of architecture. From the late last century, with the introduction of architecture by postmodern philosophy, semiotics, geographical psychology, phenomenology and cultural anthropology, there has been a cross-research between architecture and narratology. The recent research hopes to conduct an in-depth analysis of the theory of architectural spatial narrative and its development in the context of complex disciplines, and to research spatial narrative as a design methodology for architecture.

Abstract

Supply chain management intends to integrate supply chains' activities such as material flow, information flow and financial issues. Material flow management is the most significant issue since the inventory level in the whole supply chain could be optimized by an integrated plan. In other words, when one member of the supply chain plans to reduce its inventory level solely, despite reducing inventory in this node the inventory will be stocked in other partners' warehouses. Therefore, in this paper a new mathematical model has been developed to facilitate the process of finding the optimum solution in economic production, purchase and delivery lots and their schedules in a three-echelon supply chain environment; including raw material in suppliers, manufacturer and assembly facility as a customer. The manufacturer with a flow shop system provides its requirements from supplier, assemble multiple products, and delivers products to the customer (automotive OEM alike) on an optimum multiple delivery points. The delivery cycles would be identified through the production common cycle regarding the supply chain flexibility. Finally, a modified real-valued Genetic Algorithm (MRGA), and an Optimal Enumeration Method (OEM) are developed, and some numerical experiments have been done and compared as well.

Abstract

The axial capacity of light–gauge steel tube columns filled with concrete including recycled asphalt pavement (RAP) aggregates and recycled concrete aggregates (RCA) was investigated. A total of 51 specimens, including 6 bare steel tubes, 30 composite columns and 15 concrete-only columns were tested under uniaxial load. Fifteen concrete mixes were considered by replacing the weight of natural coarse aggregates (NA) with RCA and RAP at replacement levels of 0, 20, 40, 60, 80, and 100%. In addition, RAP and RCA were combined in the same mixes with replacement levels of (1) 20% RAP and 80% RCA; (2) 40% RAP and 60% RCA; (3) 60% RAP and 40% RCA; and (4) 80% RAP and 20% RCA. Experimental results were analyzed by reporting the ultimate capacities and the patterns of failure. Moreover, the predictions of EUROCODE 4 (EC4) and American Institute of Steel Construction (AISC) codes were checked. ABAQUS software was used to perform a finite element analysis (FEA) of the tested composite specimens. The results showed that using recycled aggregates decreased the carrying capacity of columns. Carrying capacity of light–gauge steel tubes filled with concrete including different combinations of RCA, NA and RAP aggregates can be conservatively predicted by the AISC and EC4 recommendations. Results of FEA showed a good agreement with the experimental results.
