Cartographic Materials and Cataloguing Standards

To excel in your examination, present this information using precise library science terminology, structured for immediate clarity.

1. Kinds of Cartographic Material

Under AACR2 and RDA, cartographic materials represent the Earth or celestial bodies at any scale. Major categories include:

• Maps (Single Sheets or Thematic): Flat representations of an area (e.g., Survey of India 1:50,000 series, thematic population maps).
• Atlases: Volumes of maps bound in book format (e.g., Oxford School Atlas).
• Globes: Three-dimensional spherical models of the Earth or sky.
• Charts: Specialized maps for navigation (e.g., nautical or aeronautical charts).
• Plans and Sections: Large-scale drawings for architectural or engineering

Influence Lines and Structural Analysis

Influence lines (IL) and their use in structural analysis. Methods of IL construction.
Internal forces and bending moments caused by moving loads can be solved with the help of influence lines. Influence line S graphs the variation of a quantity S at a specific point x on a beam or truss caused by a unit load F=1 placed at any point u along the structure.
Methods for constructing the influence line:

• Analytical method (creating equations using equilibrium conditions)
• Kinematic method (Müller-Breslau Principle; using principal of virtual work)
• Combination of above-mentioned methods
• Numerically (based on definition, i.e. tabulation of the influence values for multiple points along the structure)

Port Sizing: Key Factors

Physical Factors

1. Oceanographic and Meteorological Conditions

These conditions define navigational restrictions. Wind conditions are classified as:

• Soft: Up to 36 kph
• Moderate: 36 - 63 kph
• Severe: 63 - 108 kph

2. Vessel Dimensions

Design vessel dimensions (LOA, breadth, freeboard, draft) are crucial for port design.

3. Vessel Maneuverability

• High: Light war vessels, cruises, bulk carriers, Ro-Ro vessels, first-generation containerships
• Medium: Modern war vessels, oil carriers (T-2), bulk carriers, second-generation containerships
• Low: Aircraft carriers, VLCC tankers, third and fourth-generation containerships, older or damaged vessels

4. Vessel Squat

Two main effects:

• Vertical movement (sinking)
• Longitudinal rotation

5. Vessel Movements

Site Layout or Field Drawing

Materialization of Project Axes

Depending on the type of work, required accuracy, and project scope, equipment ranging from common tools (hose level, spirit level, steel tape measures, and other fabric measuring tapes) to more precise instruments like the telescopic level, total station, or theodolite may be used. These advanced instruments...

13. Thermal loads in Force Method.

Due to the change Of the temperature into the element the displacement of the structure is Described the following formula:

Where:

t – Is calculated: t = t_C – t₀.

t_C - current temperature in the Element at the centroid of element cross-section.

t₀ - the beginning temperature in The element.

α_t –thermal expansion ratio.

N_i – the values of axial forces in The elements under the unit force X_i.

Due to the temperature Difference around the element the displacement of the structure is Described the following formula:

Where:

Δt – is Calculated: Δt = t_u – t_d.

α_t – thermal expansion ratio.

h – a height of element cross-section.

M_i – the values of moments in the Elements under the unit force X_i.

Inventory Management

Safety Stock: The amount of inventory carried in addition to the expected demand.

Stock Keeping Unit (SKU): A common term used to identify an inventory item.

Material Requirements Planning (MRP)

Available to Promise: A feature of MRP systems that identifies the difference between the number of units currently included in the master schedule and actual (firm) customer orders.

Bill of Materials (BOM): A computer file that contains the complete product description, listing the materials, parts, and components, and the sequence in which the product is created.

Closed-loop MRP: The use of actual data from the production system to continually update the MRP system. This feedback is provided so that planning can be kept valid at all...

Open and Closed Loop Control Systems

Open Control System

An open-loop control system refers to a configuration where the controller is disconnected from the process. In this state, the controller has no influence over the controlled variable and cannot maintain the desired setpoint.

Closed Loop Control System

A closed-loop control system refers to a configuration where the controller is connected to the process. The controller continuously compares the setpoint (reference) with the controlled variable and determines the necessary corrective action.

Key Process Control Terminology

• Controlled Variable: The specific variable that must be maintained or regulated at a desired value.
• Setpoint (Reference): The target value for the controlled variable.
• Manipulated
