A Genetic Algorithm Based Feature Selection for Classification of Brain MRI Scan Images Using Random Forest Classifier

A brain tumour is a mass of tissue that is formed by a gradual addition of anomalous cells and it is important to classify brain tumours from the magnetic resonance imaging (MRI) for treatment. Magnetic Resonance Imaging is a useful imaging technique that is widely used by physicians to investigate different pathologies. After a long clinical research, it is proved to be harmless. Improvement in computing power has introduced Computer Aided Diagnosis (CAD) which can efficiently work in an automated environment. Diagnosis or classification accuracy of such a CAD system is associated with the selection of features. This paper proposes an enhanced brain MRI image classifier targeting two main objectives, the first is to achieve maximum classification accuracy and second is to minimize the number of features for classification. Feature selection is performed using Genetic Algorithm (GA) while classifiers used are Random forest Classifier

Event segmentation and biological motion perception in watching dance

We used a combination of behavioral, computational vision and fMRI methods to examine human brain activity while viewing a 386 s video of a solo Bharatanatyam dance. A computational analysis provided us with a Motion Index (MI) quantifying the silhouette motion of the dancer throughout the dance. A behavioral analysis using 30 naïve observers provided us with the time points where observers were most likely to report event boundaries where one movement segment ended and another began. These behavioral and computational data were used to interpret the brain activity of a different set of 11 naïve observers who viewed the dance video while brain activity was measured using fMRI. Results showed that the Motion Index related to brain activity in a single cluster in the right Inferior Temporal Gyrus (ITG) in the vicinity of the Extrastriate Body Area (EBA). Perception of event boundaries in the video was related to the BA44 region of right Inferior Frontal Gyrus as well as extensive clusters of bilateral activity in the Inferior Occipital Gyrus which extended in the right hemisphere towards the posterior Superior Temporal Sulcus (pSTS)

Forests Fanned by Waves: Embodied Ways of Knowing in a Mangrove Landscape

This narrative article explores a boatman's intimate relationship with the mangrove forests he had grown up with from his childhood. The author listens to the boatman's stories  about his life when he is in his sixties. How he assessed the author also implied what part of his world the author would be invited to see.  This is a narrative of warmth and friendship built through traversing the mangrove forest in a handmade raft, watching birdlife, lotuses and other mangrove species. The narrative captures the ecosophy of this boatman in his lived and embodied experience

Perception, Temporality And Symbol: A Study Of Man With Cockerel By Ranbir Kaleka (2001-2002)

This article makes an early attempt to emerge a dialogue between neuroscientific theories of perception and video art while proposing alternate lenses to view Kaleka’s installation in the context of Indian contemporary video art. The author proposes that Neuroaesthetics as a field may benefit from studying screendance and audience engagement because the conceptual complexity offered by screendance has the potential to throw light on cognitive and affective systems during emergent aesthetic episodes. Time and symbol, two critical elements that pave the way for new perception, and how these elements transform into materiality in Kaleka’s work are discussed. This discussion reveals in more depth, the illusory loop that Kaleka constructs in order to engage the audience in a deeper and more critical perception of the human condition at the interface of society, politics and economics with the techniques of video art. While the paper places greater emphasis on perception of an artwork by its audience, artists may be able to use the neurocognitive model analysis to develop different engagement strategies with their audiences. The author’s intention is to delve into an expanded investigation of aesthetic experience and perception using the elusive links between art and science

Unveiling the Collective Unconscious: A Jungian Reading of Prophetic Vision in Tahereh Mafi’s Shatter Me

This paper offers a Jungian psychoanalytic reading of Shatter Me, a young adult dystopian novel by Tahereh Mafi. It focuses on the psychological evolution of Juliette, the protagonist, who transitions from repression and isolation to empowerment and self-actualization. Based on the ideas of Carl Jung—collective unconscious, archetypes, the Shadow, and individuation—the analysis interprets the symbolic language and inner struggle of the novel. The repeated motifs, such as Juliette\u27s visions of a bird, symbolize her unconscious desire for freedom and transformation. Her changing relationships, particularly with Warner and Adam, take Juliette\u27s psyche through the integration of polarities within her. The paper also explores how Mafi’s stream-of-consciousness style and fragmented syntax mirror Juliette’s fractured mental state. Ultimately, this approach positions Shatter Me as more than a dystopian romance; it becomes a psychological allegory that reflects timeless struggles of identity, emotional trauma, and inner unity

Will Migrant Pacific Workers Be a Part of Aotearoa New Zealand’s Farming Futures? A call to design future agritech industry transformation plans with a reciprocal framework

In 2020 and 2023 the New Zealand government depicted a vision for technology-enhanced farming futures in the Agritech Industry Transformation Plan. However, the plan overlooks the critical role of seasonal, migrant Pacific workers in sustaining Aotearoa New Zealand’s horticulture industry. It also contains little practical planning for what a transition from a largely human to a largely robotic workforce should entail. We show how these omissions reflect an extractive framework which threatens workers’ wellbeing and the sustainability of Aotearoa New Zealand’s horticulture industry. We provide recommendations for how future agritech industry plans can consciously adopt a more sustainable reciprocal framework

COMPARISON OF AMINO ACIDS IN 8 DIFFERENT BOILED TROPICAL FRUITS

Objective: To determine the protein quality, especially the amino acid content of 8 tropical fruits both raw and boiled samples. Eight different tropical fruits were used in the study (Apricot, Jamun, Dragonfruit, Pomegranate, Mangustan, Litchi, Jackfruit, and Kiwi.Methods: Ninhydrin method was used for the estimation of the concentration of amino acids present in the above fruits. Raw and boiled fruits were used for the study.Results: Both raw and boiled forms which showed thats Jamun and Mangustan contained highest concentration amino acids whereas apricot shows the lowest concentration of amino acids except in Jamun which showed higher values in the raw fruit whereas in others the boiled samples showed higher values.Conclusion: It was evident that tropical fruits have a good balance of the essential amino acids (both raw and boiled fomr) which provide significant sources of protein in our diet

Design of Ripple Free Single Phase Isolated Converter using DC Active Filter with Centre Tap Transformer

A ripple current reduction method is proposed that does not require additional switching devices. A current ripple that has twice the supply frequency of the power supply is generated in the dc part when a single-phase pulse width modulated inverter is used for a grid connection. The current ripple causes shortening of the lifetime of electrolytic capacitors, batteries, and fuel cells. The proposed circuit realizes a dc active filter function without increasing the number of switching devices, because the energy buffer capacitor is connected to the center tap of the isolation transformer. In addition, the buffer capacitor voltage is controlled by the common-mode voltage of the inverter. The features of the proposed circuit are described and Simulation results are presented.Simulation results proves the ripple reduction, to approximately 20% that of the conventional circuit
