TOPIC COVERED TODAY:
Scanner
1. Optical scanners
a. Optical character Recognition(OCR)
b. Optical mark recognition(OMR)
c. Optical barcode recognition(OBCR)
2. Magnetic Ink Character Recognition(MICR)

Scanner
• It is an input device that can read text or illustrations printed on
paper and translate into digital form.
• The main advantage of these scanners is that the data need not be
entered separately resulting in saving lot of time.

• Scanners are of two types: i) optical scanners ii) MICR

Optical scanners
• a. Optical character Recognition(OCR): In this, characters are read with
the help of a light. This is used in office atomization, documentation in
library etc.
• b. Optical mark recognition(OMR): It is a technology where an OMR
device senses the presence or absence of a mark such as a pencil
mark. OMR is used in tests such as aptitude tests.
• c. Optical barcode recognition(OBCR): Barcode readers are
photoelectric scanners that read the bar codes or vertical zebra striped
marks printed on product containers. This is used in super markets,
book shops etc.

Magnetic Ink Character Recognition(MICR)
• It is a character recognition technology used primarily by the banking
industry to facilitate the processing of the cheques.
• MICR characters ( cheque No., Acc.No.etc) are printed in special ink
usually containing iron oxide.
• When a document that contains the ink needs to be read, it passes
through a machine which magnetizes the ink and there will be a
reader sorter unit which translates the magnetic information into
characters.
• MICR provides a secure, high speed of scanning and processing
information. It scans about 2600 cheques/min.

Barcode Reader(Scanner)

Barcode or Barcode Reader is an optical machine-readable representation of data relating to the object to which it is attached. Originally barcodes systematically represented data by varying the widths and spacing of parallel lines, and may be referred to as linear or one-dimensional (1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in two dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to as barcodes as well. A barcode reader uses a photo sensor to convert the barcode into an electrical signal as it moves across a barcode. Mechanism: The scanner then measures the relative widths of the bars and spaces, translates the different patterns back into regular characters, and sends them on to a computer or portable terminal. If we use barcodes, we get online information without giving any data to the computer. If the manufacturing company produces large quantity of products, then these barcodes are very useful.

Optical character recognition (OCR) is process of classification of optical patterns contained in a digital image. The process of OCR Recognition involves several steps including pre-processing, segmentation, feature extraction, classification. Pre-processing is for done the basic operation on input image like noise reduction which remove the noisy signal from image. Segmentation stage for segment the given image into line by line and segment each character from segmented line. Future extraction calculates the characteristics of character. A Radial Basis Function Neural Network (RBFNN) is used to classification contains the database and does the comparison.

ScyllaDB has the potential to deliver impressive performance and scalability. The better you understand how it works, the more you can squeeze out of it. But before you squeeze, make sure you know what to monitor! Watch our experienced Postgres developer work through monitoring and performance strategies that help him understand what mistakes he’s made moving to NoSQL. And learn with him as our database performance expert offers friendly guidance on how to use monitoring and performance tuning to get his sample Rust application on the right track. This webinar focuses on using monitoring and performance tuning to discover and correct mistakes that commonly occur when developers move from SQL to NoSQL. For example: - Common issues getting up and running with the monitoring stack - Using the CQL optimizations dashboard - Common issues causing high latency in a node - Common issues causing replica imbalance - What a healthy system looks like in terms of memory - Key metrics to keep an eye on This isn’t “Death-by-Powerpoint.” We’ll walk through problems encountered while migrating a real application from Postgres to ScyllaDB – and try to fix them live as well.

Syngulon’s technology expands the capacity for selection of microorganisms. The ability to select individual microbes with a behavior of interest is essential, whether for simple cloning at the bench, or for industry-scale production. Synthetic biology uses the concept of “bioengineering” to improve or modify existing genetic systems to create microbes with desired behaviors, and Syngulon uses this approach to develop its selection technologies. This selection technology is based on bacteriocins, ribosomally-produced peptides naturally made by most bacteria to kill competitive microbial species. These bacteriocins can have a limited or wide target range against other microbial species. This technology offers advantageous over antibiotic selection for several reasons: it avoids the use of antibiotics in the first place, helping to reduce the spread of antibiotic resistant microbes. The technology also increases product yield; as bacteriocins are generally smaller peptides, they do not impose a heavy metabolic burden on the producing cell. They can have a wide target specificity, helping to avoid genetic drift. Finally, our system is 100% plasmid-based (e.g. without chromosomal mutations), making it applicable for use in any E. coli strains.

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “Enterprise Knowledge Graphs: The Importance of Semantics” on May 9, 2024, at the annual Data Summit in Boston. In her presentation, Hedden describes the components of an enterprise knowledge graph and provides further insight into the semantic layer – or knowledge model – component, which includes an ontology and controlled vocabularies, such as taxonomies, for controlled metadata. While data experts tend to focus on the graph database components (RDF triple store or a label property graph), Hedden emphasizes they should not overlook the importance of the semantic layer.

The standard Salesforce Approval process can be limiting in many ways, especially in complex scenarios. What if there was a way to implement very flexible approvals where one can use Apex code to make data updates in unrelated records, dynamically generate next steps details, and compute assignees on the fly? And still use UI-based configurations to implement concrete approval processes. In this session, we will share ideas behind such a solution and show a few lines of code to get you started.
