Quantization is the process of mapping continuous, high-precision numerical values (like 32-bit floats) to a smaller, discrete set of lower-precision values (like 8-bit integers). Primarily used in AI and signal processing, it reduces model size, speeds up inference, and lowers power consumption with minimal loss in accuracy.

Key Aspects of Quantization:

How it Works: It compresses data by converting complex floating-point weights and activations into integers (e.g., FP32 to INT8 or INT4).

AI/LLM Benefits: Quantization makes large models (LLMs) smaller and faster, allowing them to run on edge devices like mobile phones, while reducing memory usage and operational costs.

Types:

Post-Training Quantization (PTQ): Applied after a model is trained to reduce size.

Quantization-Aware Training (QAT): Models the loss of precision during training to improve accuracy.

Trade-off: While it improves efficiency, reducing precision can lead to a slight decrease in model accuracy.

Other Applications: Beyond AI, it is used in digital signal processing (e.g., converting audio/images to digital) and music production to align MIDI notes to a timing grid

Coursework Overview

In this assignment, you will analyse two commonly used residential heating systems by applying

thermodynamic principles. Your analysis should include the determination of the energy input for each system,

the evaluation of the operating costs, the assessment of carbon footprint, and the recommendation of system

improvements.

Coursework Tasks to be Completed by Students

Table 1 shows a list of the most common residential heating options. According to Table 1, two heating

systems will be assigned to you, depending on your student ID’s last digit (S). For example, if your ID

number is 12345678, then S=8, so the assigned two heating systems are Heat Pumps and Fireplaces. You

will analyse these systems according to the principles of thermodynamics.

For the two options that have been assigned to you and assuming an 80 m2 house in Newcastle:

a) Identify the physical process of the two heating systems in terms of thermodynamics, heat

production, energy losses, heat transport, etc.

b) Evaluate the energy output and performance of the two systems.

c) Compare installation cost, carbon footprint, and annual cost of electricity or fuel charges.

d) Select the option with the lowest cost assuming a 12-year life span.

e) Choose the optimal option if fuel or electricity prices double to what they are now.

f) Propose solutions and/or improvements that might solve some of the problems of one of the

systems.

Expected Size of Submission

You will submit an A0-sized poster presentation in PowerPoint format. The PowerPoint presentation must

include calculations, diagrams, figures, tables, and text. All together (figures, calculations, tables and so on)

is equivalent to 2500 words.

Referencing Style

You must write your coursework using the Cite Them Right version of the Harvard referencing system. An

online guide to Cite Them Right is freely available to Northumbria University students at

Referral

The Referral Attempt opportunity will generally take place after the end-of-level Progression and Awards

Board (PAB). If you become eligible to complete a Referral Attempt but are subsequently unable to

undertake the opportunity when required, you will be permitted to re-sit the module at the next scheduled

sitting of the module assessment. This will typically entail the suspension of your progression on your

programme of study until such time that you have completed the level and become eligible to proceed.

Question 1.

A particle of mass m is attached to the rim of a disc of radius R that is pinned at its centre as shown. One end of a spring of stiffness k is attached to a drum of radius r that is itself rigidly attached to the disc. Knowing that the spring is unstretched when = 0, use the principle of virtual work to determine the value(s) of at equilibrium.

Question 2.

A ring of mass m slides without friction along a rod that is fixed at an angle with respect to the horizontal. A particle of mass M is attached to the ring with an inextensible, massless string of length L. Write Lagrange’s equations for the system.
