Lean manufacturing is a systematic approach aimed at eliminating waste and improving efficiency in production processes. It focuses on delivering value to the customer by optimizing resources and streamlining operations. The primary goal of Lean is to maximize value while minimizing waste, which is defined as anything that does not add value to the product or service. Key principles of Lean manufacturing include: 1. **Value**: Understanding what customers consider valuable and focusing on delivering it. This often involves direct communication with customers to learn their needs and preferences.
A bottleneck in production refers to a stage in a process that reduces the overall speed or efficiency of the entire system. It is typically the point where the capacity is limited and cannot keep up with the demand or output requirements of the subsequent stages. This limitation can cause delays, increased lead times, and decreased productivity.
Material Requirements Planning (MRP) is a production planning, scheduling, and inventory control system used to manage manufacturing processes. MRP ensures that the right materials are available for production at the right time, while also maintaining the lowest possible inventory levels.
The Shifting Bottleneck Heuristic is an optimization technique commonly used in scheduling problems, particularly in job shop scheduling and flow shop scheduling scenarios. The primary objective of this heuristic is to improve performance by focusing on the scheduling of the most critical resources or "bottlenecks" in the production or processing sequence. **Key Concepts:** 1. **Bottleneck:** A bottleneck is a stage in a process that reduces the overall speed of the entire system.
Kernel preemption is a feature of operating systems, particularly within the context of the Linux kernel, that allows a running process to be interrupted so that the operating system can switch to another process. This mechanism is crucial for allowing a responsive multitasking environment, enabling the system to handle various processes efficiently. In preemptive multitasking systems, the kernel can suspend the execution of a process to allocate CPU time to another process that is ready to run.
The point of subjective simultaneity (PSS) is a concept in the study of perception and time within the field of psychology and neuroscience. It refers to the moment at which two stimuli are perceived as occurring simultaneously by an observer, even if they are presented at different times according to an objective time scale. This concept is often explored in experiments involving auditory and visual stimuli.
The mathematical principles of reinforcement primarily relate to the field of reinforcement learning (RL), which is a subset of machine learning. Reinforcement learning focuses on how agents should take actions in an environment to maximize some notion of cumulative reward. Here are some key concepts and principles related to the mathematics of reinforcement learning: 1. **Agent, Environment, and Rewards**: - **Agent**: The learner or decision maker. - **Environment**: Everything the agent interacts with.

Douglas N. Jackson is a notable figure in the field of psychology, particularly known for his contributions to the development of personality assessment tools. He is best recognized for creating the Jackson Personality Inventory (JPI), which is a widely used psychological assessment instrument designed to measure various aspects of personality and individual differences. Jackson's work often focuses on the empirical study of personality and the development of reliable methods for personality assessment.
The Center for Quantum Information Science & Technology (CQIST) is typically an interdisciplinary research center focused on advancing the field of quantum information science and technology. Although specific details may vary depending on the institution, such centers generally engage in a range of activities related to quantum computing, quantum communication, quantum cryptography, and related areas. Key activities and goals of such centers may include: 1. **Research and Development**: Conduct cutting-edge research in quantum algorithms, quantum hardware, and applications of quantum technology.
The Dining Philosophers Problem is a classic synchronization problem in computer science and an example of a problem of concurrency. It illustrates the challenges of resource sharing and avoiding deadlock in a multi-threaded environment. ### Problem Description: The setup involves five philosophers who spend their lives alternately thinking and eating. They sit around a circular dining table with a fork placed between each pair of philosophers. In order to eat, a philosopher must have both forks (one from either side).
D-Wave Two is a quantum computer developed by D-Wave Systems, Inc. It was introduced in 2013 as an improvement over its predecessor, the D-Wave One. The D-Wave Two system implements quantum annealing, a specific type of quantum computing that leverages quantum mechanics to solve optimization problems.
The Elitzur–Vaidman bomb tester is a thought experiment in quantum mechanics, proposed by physicists Avshalom C. Elitzur and Lev Vaidman in 1993. It illustrates the concept of using quantum superposition and interference to perform measurements that can detect the presence of a potentially dangerous object (like a bomb) without detonating it.
KLM protocol, short for "Knuth-Liu-Meng," is a specific type of protocol used in distributed systems, particularly in the context of consensus algorithms and communication between nodes. It was proposed to help achieve consensus in a fault-tolerant manner, addressing challenges such as message passing in unreliable environments. However, it’s important to clarify that KLM typically refers to specific algorithms or methods that are aimed at improving the efficiency and reliability of distributed computing.
A Quantum LC circuit is a type of quantum circuit that is based on the principles of quantum mechanics and utilizes the properties of inductance (L) and capacitance (C) to create electrical circuits that can exhibit quantum behaviors. The "LC" in the name refers to the combination of inductors (L) and capacitors (C) that form resonant circuits.

D* (pronounced "D-star") is a dynamic pathfinding algorithm used in robotics and artificial intelligence for real-time path planning in environments where obstacles may change over time. It is particularly useful in situations where a robot needs to navigate through a space that may have shifting or unknown obstacles. D* was originally developed for applications in mobile robotics, allowing a robot to efficiently update its path as the environment changes.
The Quantum Cramér–Rao bound (QCRB) is a fundamental result in quantum estimation theory. It generalizes the classical Cramér-Rao bound to the realm of quantum mechanics, providing a theoretical lower limit on the variance of unbiased estimators for quantum parameters. ### Key Concepts: 1. **Parameter Estimation**: In quantum mechanics, one often wishes to estimate parameters (like phase, frequency, etc.) of quantum states.
Quantum illumination is a protocol and concept in quantum information science and quantum optics, which is primarily used for the detection of weak signals in the presence of noise. It is based on the principles of quantum mechanics and leverages entanglement and quantum correlations to improve detection performance. In classical sensing scenarios, detecting a faint signal (like a weak reflection from an object) can be challenging because of environmental noise that obscures the signal. Quantum illumination utilizes pairs of entangled photons.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
