In this era of pervasive connection and data collecting, it is more important than ever that people have access to and control over their own health data. This presentation offers a comprehensive overview of the most recent techniques and algorithms for the expedited processing of health-related data. Individuals may now gather and track an unprecedented amount of data about their health and fitness thanks to wearable devices, smartphone applications, and Internet of Things (IoT) sensors. The potential benefits of better health outcomes, accelerated research, and patient empowerment may be enormous if this data could be managed correctly. This article digs into the innovative programs and algorithms that are changing the face of current healthcare data management. First, we examine the scalability, security, and interoperability of current data storage and retrieval techniques in detail. Some examples of information that might be collected, saved, and accessed with the use of such devices include physiological measurements, data on lifestyle choices, and medical records. This abstract also investigates potential future applications of innovative data processing and analysis techniques for gathering data on the health of the general public. Innovative methods for health data management, such as blockchain and federated learning, are discussed in depth in the abstract. By facilitating the safe and transparent exchange of data between academics, healthcare providers, and patients, technology developments like these foster collaboration and accelerate medical research. The study emphasizes the significance of users having control over and ownership of their data in health data management. Customizable dashboards, mobile applications, and user interfaces that are made as simple as possible allow people to actively engage with their own health data and make informed decisions. The vast potential of the health data landscape may be tapped with the help of state-of-the-art

OPC (optical Proximity Correction) technology has been evolving to assist on the continues improvement of pattern resolution. One approach for further extending lithography resolution is ILT (Inverse Lithography technology). This technology, based on applying an inverse model to the target design, creates curves from the design layouts. The adoption of ILT is now enabled by the improvement of runtime obtained by enhancements in algorithms and computing power as well as the new generation of mask writers (multibeam) which enables writing complex features in an acceptable time. The last blocking points were the data volume required to store, and the challenge of handling complex structures. If the standard data storage is used, curvilinear shapes are stored as polygons, which produces larger file sizes. The file size issue has been identified and addressed by the industry in recent years. File formats proposing compact ways to represent curves usually propose Implicit Bezier and B-Spline as main curve representations. The recent development of High-NA lithography requires anisotropic scaling of the patterns for writing on mask (4x, 8x). This adds another challenge to the data preparation flow to maintain the benefits of the proposed curve representations. This work assesses the impact of adoption of curvilinear representations, with the spotlight on the needs for High-NA mask data preparation.

The modern solutions for fetching content from PDF documents or images includes fetching document’s multiple features like processing using Natural Language Processing (NLP), border-less table contents, processing it’s stacked lines, fetching document layout information and working on region-based features from documents. There are new challenges like fetching a table’s content where the table is included in borders of other content. In this paper, we have used LayoutLM for parsing the content and RetinaNet for table detection in a particular document. The pretrained models were trained on very less data-set to decide for large scale use. We also have discussed architecture of LayoutLM and tesseract that we used in building the tool with discussing output of some other approaches. © Grenze Scientific Society, 2023.

The global datasphere is experiencing significant expansion, largely driven by the relentless advancement of artificial intelligence technology. Cold data, in particular, is garnering increasing attention and is now considered a vital asset, constituting a substantial portion of data capacity. optical discs stand out as a highly promising solution for cold data archiving due to their robust data security, longevity, durability, and non-volatile nature. Additionally, their total cost of operation (TCO) further enhances their appeal. To increase the recording density, signal processing techniques must evolve along with the degradation of signal quality. In this paper, we conduct a comprehensive study of partial response maximum likelihood (PRML) detection based on simulation and real signal testing and compare an adaptive equalized detection scheme with a neural network equalized detection method for BD-ROM and BDXL systems. Results show the effectiveness of PRML method for both BD-ROM and BDXL. The neural network equalized detection method can also improve the detection performance of BD-ROM and BDXL at lower signal-to-noise ratio (SNR) levels.

In this paper, we propose a super-resolution holographic data storage system based on deep learning. A low-pass filter was introduced into the Fourier plane to remove the high frequency. This produces a blurred intensity image of the reconstructed beam. A convolutional neural network is used to establish the relationship between the blurred intensity image and the data page. The encoded phase data page can be directly demodulated from a captured intensity image, which is a non-interferometric method without iterations. The function of the filter is to generate the blurred intensity image and to reduce the recording area to improve the recording intensity. Usually, the limit of the aperture is the Nyquist size. Here, by introducing embedded data on the phase data page, the aperture size of the recording can be reduced to smaller than the Nyquist size. A simulation experiment was established to verify the effectiveness of the proposed method. © 2023 SPIE.

Tulu, largely spoken in coastal Karnataka, has a distinct alphabet that used to be written on palm leaves. This study addresses the scarcity of efficient OCR solutions. Employing machine learning algorithms that include decision tree, k-nearest neighbors (KNN), and random forest. The system achieves its highest accuracy of 92.35% with the random forest algorithm. The system's versatility in handling diverse font styles and sizes is crucial for Tulu character recognition. The inclusion of a classifier-level fusion strategy enhances recognition accuracy, which is vital given the intricate nature of Tulu characters. This research advances OCR technology for Indian languages, specifically meeting the unique needs of the Tulu script. The effectiveness of the random forest algorithm, achieving high accuracy, underscores its potential for broader applications. The proposed Tulu Character Recognition System represents a pivotal step in addressing the OCR gap for Indian languages, holding promise for future linguistic technology advancements. © 2024 IEEE.
