Abstract : Egypt is renowned for hosting a diverse array of special events and temporary activities annually, encompassing cultural, tourism, sports, and religious gatherings. Despite the vibrancy these events bring, many of these events lack a regulatory framework to mitigate their adverse effects on the host region. The key adverse outcomes of these occurrences include event ineffectiveness, strain on infrastructure and services, financial detriments, and ecological and societal repercussions. Conversely, the temporary urbanism strategy can be employed to enhance the organization and effectiveness of temporary events and activities. Despite its significance, this approach is not currently implemented in the context of Egyptian context. Consequently, this study seeks to investigate the feasibility of integrating the temporary urbanism approach into the coordination of events and activities within Egyptian context. This involves developing a framework for the design of temporary special event sites. And to reach the goal of the research, the methodology used depends on a preliminary theoretical review of temporary urbanism, covering its essential elements and core concepts. Following this, the characteristics of transient events and activities in Egypt are examined, considering their impact on the host sites as well as their potential benefits and drawbacks. Secondly, building a proposed theoretical framework for dealing with temporary events in Egyptian context. Finally, a survey engaging academic and professional experts is carried out to evaluate the practicality of applying this model to Egyptian context. The research concludes by proposing a framework for designing temporary event sites and dealing with events and activities, which contributes positively to achieving sustainability and flexibility, in addition to being a tool for planners and event managers that contributes to managing the event efficiently and effectively..

Abstract : Speech enhancement is a field of research that aims to improve the quality of speech communication in noisy environments. In this paper, we provide an overview of the key issues and challenges in speech enhancement, including the impact of noise on speech quality, the need for effective noise reduction techniques, and the importance of evaluation metrics. We also review a range of speech enhancement techniques, including traditional signal processing methods and more recent machine learning-based approaches such as deep neural networks and convolutional neural networks. We discuss commonly used speech databases for speech enhancement research and highlight the strengths and limitations of signal processing and machine learning techniques. We also review commonly used speech enhancement metrics, including objective measures such as signal-to-noise ratio and subjective measures such as mean opinion score. Finally, we discuss potential future horizons for speech enhancement research, including the integration of multiple techniques, real-time processing, robustness to diverse acoustic conditions, multilingual speech enhancement, personalized algorithms, and the development of more sophisticated evaluation metrics. Overall, this paper provides a comprehensive overview of speech enhancement research, and highlights some of the most promising directions for future research in this field..
