Abstract

This work, presents a novel optimizer called fertilization optimization algorithm, which is based on levy flight and random search within a search space. It is a biologically inspired algorithm by the fertilization of the egg in reproduction of mammals. The performance of the algorithm was compared with other optimization algorithms on CEC2015 time expensive benchmarks and large scale optimization problems. Remarkably, the fertilization optimization algorithm has overcome other optimizers in many cases and the examination and comparison results are encouraging to use the fertilization optimization algorithm in other possible applications.

Abstract

Telemedicine is one of the most rapidly developing areas of healthcare and it plays an increasing role in modern medicine. As the amount of data and demand for features increase, the data paths are becoming ever-more complex. Owing to this, it is vital in telemedicine to find a proper balance between consistency and availability under any given circumstances. However, making a trade-off can significantly influence the quality of the data. This study seeks to get an in-depth view of the problem by considering a real-world telemedicine use-case and elaborating the formal system specification of the scenario. After evaluating the specification, the constructed state graph is examined using graph coloring and other graph algorithms.

Abstract

Distinct technological trends seriously influence the modern software architectures. In this paper, four different software architectures and framework combinations were generally compared. The basis for the analysis is the developer's productivity.

In a 3 year-long research and development project, a real-world telemedicine application was efficiently implemented four times with various software architectures and architectural patterns. More than 5,000 person-hours were spent on carrying out them.

At present, a unique dataset is available, which provides the opportunity to compare the cost of spent person-hours in different approaches.

The goal of this research is to describe the measurement approach, the dataset and the applied architectures considering the software developer's productivity.

Abstract

Scours creation in riverbed at the Hričov weir is a permanent problem since its construction. It is caused by the shortened stilling basin of the weir. In almost all cases of flow control at the weir the energy is not dissipated sufficiently. A 3D physical model was built in the hydraulic laboratory to investigate the measures for reduction of the scour creation. To simulate uneven loads on the downstream riverbed, a flood discharge controlled by the weir in symmetric and asymmetric operations was used for simulations. The scours were evaluated using short-range photogrammetry for contactless measurements. Based on this method digital models of the riverbed for each simulation were created and the scours were assessed to determine the effect of the investigated measures on scour reduction.

Abstract

With the rise of the urban renewal motion in recent years in China, more and more cities have shifted the focus of construction to the renovation and renewal of old areas. The renewal of the old community plays an essential role in the urban upgrading of China, which is related to the quality of a city, as well as a crucial criterion for evaluating the comfort of the living environment. The old community to retain their vibrancy and culture is needed to renew by a way of modernization. The paper will discuss how to use micro-renewal design to improve the quality of the old community, awaking the historical memories of the community simultaneously, thereby balance the relationship between history and use-value.

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

Despite the clear benefits of maintaining a human relationship with nature, people increasingly live in urban settings. As a result of urbanization, numerous urban communities are confronting social and natural problems, which have genuinely compromised residents’ wellbeing and health. Thus, holistic planning and designing are needed to tackle these problems, integrating nature-based thinking into urban environmental development. The aim of this paper is to explore components of a sustainable city and biophilic design patterns and analyze the relationship between them. Finally, the conceptual model of a sustainable city has been proposed based on biophilic design approaches.

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.
