    Electrocardiography (ECG) signal recognition is one of the popular research topics for machine learning. In this paper, a novel transformation called tower graph transformation is proposed to classify ECG signals with high accuracy rates. It employs a tower graph, which uses minimum, maximum and average pooling methods altogether to generate novel signals for the feature extraction. In order to extract meaningful features, we presented a novel one-dimensional hexadecimal pattern. To select distinctive and informative features, an iterative ReliefF and Neighborhood Component Analysis (NCA) based feature selection is utilized. By using these methods, a novel ECG signal classification approach is presented. In the preprocessing phase, tower graph-based pooling transformation is applied to each signal. The proposed one-dimensional hexadecimal adaptive pattern extracts 1536 features from each node of the tower graph. The extracted features are fused and 15,360 features are obtained and the most discriminative 142 features are selected by the ReliefF and iterative NCA (RFINCA) feature selection approach. These selected features are used as an input to the artificial neural network and deep neural network and 95.70% and 97.10% classification accuracy was obtained respectively. These results demonstrated the success of the proposed tower graph-based method.

    An examination of film illumination aptitude to influence audience's feelings and attitudes towards what is displayed in front of them of shots and scenes. Existing illumination procedures have been reviewed thoroughly, and two essential hue groups (i.e., warm and cold tones) have been distinguished and ought to be inspected to address the study questions and form its conclusions. To produce the required proof to this exploration work, a few analyses with a delegate sample of viewers took place. These tests proved the existence of straight associations between different hues of film illumination and the recognized look of film actors. Furthermore, some hues of illumination showed more ability compared to others in modifying the recognized look of film actors. The investigation wrapped up that viewers' opinion of looks and appearances within film shots is connected, even partially, to various illumination hues.

    This study investigates the knowledge resources informing television and film lighting design practice in Egypt, and the value of suggesting scientific recommendations to be followed. A questionnaire was circulated to a considerable number of professional lighting designers, lighting directors, directors of photography and cameramen working in the Egyptian media industry. Most of those addressed by the study survey indicated that their main knowledge resource during working is likely to be their own past experience and that very few of them depend on the recommendations of scientific research. Moreover, the critical analysis of the collected data illustrated that there is limited academic research in the discipline of lighting design available for Egyptian television and film practitioners to read and benefit from the generated results and findings. It was concluded that the discipline of lighting design needs more scientific research to establish a database of findings, theories, and paradigms just as any other design discipline.
  • 'Quantifying the unquantifiable: the color of cinematic lighting and its effect on audience’s impressions towards the appearance of film characters.

    This study is an attempt to investigate the ability of different colors used in cinematic lighting designs to affect audience’s impressions towards the appearance and mood of film characters. The study critically appraised existing cinematic lighting techniques and identified the two basic color groups (i.e., warm and cold colors) that should be examined in order to answer the research questions and formulate its conclusions. To provide the needed empirical evidence for this research work, some experiments with a representative sample of viewers were conducted. These experiments confirmed the existence of direct relationships between various colors of lighting and the perceived appearance and mood of film characters. Moreover, specific color hues of lighting appeared to be more effective than others in altering the perceived appearance and mood of film characters. The study concluded that audience’s perception of appearances and moods within cinematic images is linked, even in part, to different colors of lighting.

    Surrealism is not just an art or literature movement; Surrealism is a way to express feelings and emotions and tell a story. Filmmakers heavily used Surrealism in their science fiction movies and T.V. series. Rick and Morty has been praised for its animation style, described as "visually stunning" and "incredibly detailed. The show also features a wide variety of surrealistic locations. Rick and Morty has also been honored for its writing, which often features dark humor and satire. The show has been praised for its ability to tackle difficult topics humorously and for its ability to blend science fiction and comedy, creating a unique and entertaining animation series. This research aims to reveal the surreal elements in Rick and Morty’s fantasy world and its adaptation in the first eleven episodes. Research hypothesis: Filmmakers who apply surrealism to their science fiction movies will boost the magical look and feel in their shows better than filmmakers who do not employ surreal elements. The researcher used Analytical descriptive methodology in his research and discovered The criteria used to identify the critical use of surrealism in since fiction series and found rick and Morty a comprehensive source of surrealist approaches in the placement of the surreal elements in Rick and Morty's first season's fantasy world.
