Improved attention-based PCNN with GhostNet for epilepsy seizure detection using EEG and fMRI modalities: extractive pattern and histogram feature set
No full textIntroductionDetecting epileptic seizures remains a major challenge in clinical neurology due to the complex, heterogeneous, and non-stationary characteristics of electroencephalogram (EEG) signals. Although recent machine learning (ML) and deep learning (DL) approaches have improved detection performance, most methods still struggle with limited interpretability, inadequate spatial–temporal modeling, and suboptimal generalization. To address these limitations, this study proposes an enhanced hybrid parallel convolutional-GhostNet framework (HPG-ESD) for robust seizure detection using multimodal EEG and functional Magnetic Resonance Imaging (fMRI) data.MethodsThe experimental data consist of pediatric scalp EEG recordings from 24 subjects in the CHB-MIT dataset (22-channel 10–20 system, 256 Hz sampling, continuous multi-hour recordings) and resting-state 3T fMRI scans from 52 participants in the UNAM TLE dataset (26 epilepsy patients and 26 healthy controls). EEG data underwent Gauss-based median filtering, while fMRI images were denoised using an adaptive weight-based Wiener filter. Spatial, temporal, and spectral EEG features were extracted alongside an enhanced common spatial pattern (E-CSP) representation, whereas fMRI features were obtained using deep 3D CNN embeddings combined with a smoothened pyramid histogram of oriented gradients (S-PHOG) descriptor. These multimodal features were fused within a soft voting hybrid parallel convolutional–GhostNet (S-HPCGN) model, integrating an improved attention based parallel convolutional network (IAPCNet) and GhostNet to capture complementary spatial–temporal patterns.ResultsThe proposed HPG-ESD framework achieved an accuracy of 0.941, precision of 0.939, and sensitivity of 0.944, outperforming conventional unimodal and state-of-the-art methods.DiscussionThese results demonstrate the potential of multi-modal learning and lightweight attention-enhanced architectures for reliable and clinically relevant seizure detection
A System for Movement Detecting Congestion.
No full textIn this paper, we present a system for tracking and provide early information of hazardous locationsin huge gatherings. It is based on optic flow estimations and detects sequences of crowd motion that are characteristic for devastating congestions. For optic flow computation, Lucas- Kanade method is employed to determine the optical flow vectors for the gathered video. Segmentation of video sequences is done and optic flow is determined for respective segments. A threshold optic flow is chosen in such a way that the tracking of congested area in video is easilydoneby comparing it with respective segment’s determined optic flow values. Finally, we present the location of crowd congestion which helps in taking further protective measures to handle unusual events.  </jats:p
Unveiling Domesticity: Everyday Life and Lived Experiences in Shakespeare's Select Comedies
No full textShakespeare’s plays have long captivated scholars and lay readers alike, inviting multiple readings and interpretations aimed at uncovering the layered, often hidden meanings embedded in his works. The profound worldly wisdom Shakespeare imparts and his keen observation of human nature stem, in part, from his deep acquaintance with the lives of both rural and urban communities. Born in Stratford-Upon-Avon, a small English town, Shakespeare’s formative years were shaped by the rhythms of provincial life. Later, his relocation to London and his professional successes in the city’s vibrant playhouses exposed him to the complexities of urban existence. These dual experiences—rural simplicity and urban sophistication—imbued his works with a rich tapestry of human experiences, reflected in his nuanced portrayal of everyday life. Shakespeare’s unparalleled ability to depict the domestic world of his time is especially evident in his comedies. These plays often serve as windows into the household dynamics, social customs, and intimate relationships of the early modern period. The domestic sphere, encompassing themes of marriage, family life, gender roles, and economic concerns, is intricately woven into the narratives, creating a mirror for the audiences of his day to reflect on their own lives. His comedies, in particular, lend themselves to a careful examination of how the ordinary yet essential aspects of domesticity intersect with broader social and cultural structures. This paper seeks to explore the ways in which Shakespeare’s own lived experiences—rooted in the everyday lives of villagers in Stratford-Upon-Avon and city dwellers in London—inform his artistic portrayal of domestic life. By undertaking a general survey of domestic life during the early modern period, this study contextualizes Shakespeare’s treatment of domesticity within the cultural and historical framework of his era. It further investigates how the themes of household affairs, interpersonal relationships, and societal expectations manifest in selected comedies, revealing Shakespeare’s acute sensitivity to the interplay between the personal and the social. Ultimately, this analysis aims to illuminate how Shakespeare’s comedies resonate with universal truths about human existence while capturing the specificities of domestic life in his time.

Development of efficient, stable organic-inorganic hybrid solar cells
No full texttextDeveloping a fundamental understanding of photocurrent generation processes at organic-inorganic interfaces is critical for improving hybrid solar cell efficiency and stability. This dissertation explores processes at these interfaces by combining data from photovoltaic device performance tests with characterization experiments conducted directly on the device. The dissertation initially focuses on exploring how morphologically and chemically modifying the organic-inorganic interface, between poly(3-hexylthiophene) (P3HT) as the electron donating light absorbing polymer and titanium dioxide (TiO₂) as the electron acceptor, can result in stable and efficient hybrid solar cells. Given the heterogeneity which exists within bulk heterojunction devices, stable interfacial prototypes with well-defined interfaces between bilayers of TiO₂ and P3HT were developed, which demonstrate tunable efficiencies ranging from 0.01 to 1.6 %. Stability of these devices was improved by using Cu-based hole collecting electrodes. Efficiency values were tailored by changing TiO₂ morphology and by introducing sulfide layers like antimony trisulfide (Sb₂S₃) at the P3HT-TiO₂ interface. The simple bilayer device design developed in this dissertation provides an opportunity to study the precise role played by nanostructured TiO₂ surfaces and interfacial modifiers using a host of characterization techniques directly on a working device. Examples introduced in this dissertation include X-ray photoelectron spectroscopy (XPS) depth profiling analysis of metal-P3HT and P3HT-TiO₂ interfaces and Raman analysis of bonding between interface modifiers like Sb₂S₃ and P3HT. The incompatibility of TiO₂ with P3HT was significantly reduced by using P3HT derivatives with -COOH moieties at the extremity of a polymer chain. The role of functional groups like -COOH in interfacial charge separation phenomena was studied by comparing the photovoltaic behavior of these devices with those based on pristine P3HT. Finally, for hybrid solar cells discussed in this dissertation to become commercially viable, high temperature processing steps of the inorganic TiO₂ layer must be avoided. Accordingly, this dissertation demonstrates the novel use of electromagnetic radiation in the form of microwaves to catalyze growth of anatase TiO₂ thin films at temperatures as low as 150 °C, which is significantly lower than that used in conventional techniques. This low temperature process can be adapted to a variety of substrates and can produce patterned films. Accordingly, the ability to fabricate TiO₂ thin films by the microwave process at low temperatures is anticipated to have a significant impact in processing devices based on plastics.Materials Science and Engineerin
