Core Metrology Concepts

• Accuracy: The degree of approximation of a measurement to the actual or conventional value.
• Precision: The ability of an instrument to consistently reproduce measurement results.
• Appreciation: The smallest unit fraction readable on an instrument.
• Conventional Value: The standard value used as a reference for manufacturing.

Error Analysis

• Absolute Error: The difference between the measured value and the conventional magnitude.
• Relative Error: The ratio of the absolute error to the conventional value magnitude.

Measurement Methods

• Direct Measurement: Reading values directly from instrument divisions.
• Comparison Measurement: Measuring differences between an unknown dimension and a known pattern.
• Verification Measurement: Checking

Organization

Organization is a pattern of many interwoven, simultaneous relationships through which people under a director or manager pursue their goals.

Task in Organization

Organizational Design is the determination of the organizational structure that is most appropriate for a strategy, people, technology, and tasks of the organization.

Organizational Structure

The organizational structure is the way in which the organization's activities are divided, organized, and coordinated. It is a basic framework within which managers' decision making takes place.

Building Blocks

1. Division of work
2. Departmentalization
3. Organizational hierarchy
   • Tall: narrow span; many levels between high and low managers; long chain of command
   • Flat: wide span; fewer management levels

Primerjava vrelišč organskih spojin

Spojina z daljšo verigo ima višje vrelišče, spojina z manj razvejano verigo ima višje vrelišče. Karboksilne kisline imajo višja vrelišča kot alkoholi, sledijo ketoni, aldehidi (podobno), estri, etri in ogljikovodiki.

Reakcije eliminacije in sinteza alkenov

• propan-2-ol (CH₃-CH(OH)-CH₃) CH₂=CH-CH₃ (propen)
• 2-metilpropan-1-ol (CH₃-CH(CH₃)-CH₂OH) → CH₃-C(CH₃)=CH₂ (2-metilpropen)
• 2-feniletanol (CH₂OH-CH₂-C₆H₅) → CH₂=CH-C₆H₅ (fenileten)
• 2-metilpropan-2-ol (CH₃-C(OH)(CH₃)-CH₃) → CH₃-C(CH₃)=CH₂ (2-metilpropen)
• cikloheksanol (šestkotnik-OH) → cikloheksen (šestkotnik s črtico znotraj)

Oksidacija aromatskih derivatov

• šestkotnik 1-CH₂CH₂CH₃, 2-CH₃ šestkotnik 1-COOH, 2-COOH (benzen-1,2-dikarboksilna

8 Essential Information Architecture Principles

The Principle of Objects

This principle focuses on how you see your content. You should try to see it as a living thing—complete with its own lifecycle, behaviors, and characteristics.

The Principle of Choices

People often have the illusion that they want as many choices as possible. However, the more choices we have to make, the more cognitive power it takes for us to actually make the call. This may even cause anxiety. This is why it is better to create specific categories; otherwise, users can easily get lost.

The Principle of Disclosure

People can only process new information in a certain way. This principle is about showing more information depending on the stage or page you are looking for....

Excellent managers come in all shapes and sizes. Their management style can be as unique as their personalities. Here are five things the best managers do – and don’t do.

What Effective Managers Do:

On the positive side, the best managers:

1. Keep the big picture in mind – They have a sound strategic mindset. They know their company’s business well and ensure that the activities of their unit, department, or division are always firmly aligned with broader initiatives and strategies.
2. Are consistent in their behavior – People like and need predictability. Problems arise for employees when a manager is erratic – for example, lenient and upbeat one day, and controlling and dour the next.
3. Treat their employees’ time as if it’s as important
