Arbitration in CAN is a process of resolving conflicts when multiple nodes try to transmit data simultaneously.

• Arbitration is used in Controller Area Network (CAN) to ensure that only one node transmits data at a time.

• Each node on the CAN bus has a unique identifier, and the node with the highest priority identifier gets to transmit its data first.

• If two or more nodes try to transmit data at the same time, the arbitration process determines which node has the highest priority...read more

Duplicate values can be created by copying the original values and inserting them again into the dataset.

• Copy the original values in the dataset

• Insert the copied values back into the dataset

Elastic stack is a collection of open-source tools for data ingestion, storage, search, and visualization.

• Includes Elasticsearch for search and analytics

• Includes Logstash for data collection and parsing

• Includes Kibana for data visualization and dashboarding

• Can also include Beats for lightweight data shippers

Factory creates objects without specifying the exact class, while builder constructs complex objects step by step.

• Factory pattern creates objects without specifying the exact class to create, using a common interface.

• Builder pattern constructs complex objects step by step, allowing different representations of an object to be created using the same construction process.

• Factory pattern is used when the creation process is simple and does not require many parameters, while buil...read more

Aircraft maintenance involves regular inspections, repairs, and servicing to ensure safe and efficient operation.

• Perform regular inspections of aircraft components and systems

• Follow manufacturer's maintenance guidelines and schedules

• Replace worn or damaged parts as needed

• Keep detailed maintenance records for tracking and compliance purposes

• Adhere to safety regulations and standards

• Utilize specialized tools and equipment for maintenance tasks

An optimizer is a software tool or algorithm used to improve the performance of a system by minimizing errors or maximizing efficiency.

• Optimizers are commonly used in programming languages to improve code execution speed and reduce memory usage.

• Examples of optimizers include compiler optimizers, database query optimizers, and machine learning model optimizers.

• Optimizers work by analyzing code or data to identify inefficiencies and then making adjustments to improve performanc...read more

LSTM stands for Long Short-Term Memory, a type of recurrent neural network (RNN) architecture.

• LSTM networks are designed to overcome the vanishing gradient problem in traditional RNNs.

• They are capable of learning long-term dependencies in data sequences.

• LSTM networks have gates (input, output, forget) that regulate the flow of information within the network.

• They are commonly used in tasks such as speech recognition, language modeling, and time series prediction.
