Papers, Notes, Lists etc. Here you will find some technical papers, notes and lists on subjects that interest me. Feel free to save or print these.

• Paper: Kelvin Functions and their Derivatives provides a brief background history and presentation of the functions up to the 4th derivative.

• List: Pressure Vessel Reading List here is a short list of some of the key books and papers related to pressure vessels that I have found useful.

• Note: AutoCAD useful notes for engineers and draughtsmen gives some setup rules that I have found to be useful reminders given the various releases of AutoCAD that are currently in use.

• Paper: Engineering Activities, man-hour estimates gives some guidance for the preparation of man-hour estimates so that project management cost and time scale estimates can be made.

• Paper: Oval Pipe a Non-Linear Problem provides a brief introduction to an interesting stress analysis problem of an out-of-round pipe (or tube) subjected to internal pressure.

• Paper: Essential Checking of Finite Element Analysis This document describes the essential checking requirements necessary to ensure that a Finite Element Analysis (FEA) has a reasonable chance of being correct.

• List: Pressure Piping Reading List here is a short list of some of the key books and papers related to pressure piping that I have found useful.

• Research Technical Note: Motor Ship Swanley and its Double-acting Diesel Engine The Swanley was the first British built ship with a double-acting diesel engine. The engine was not a success but did have some unique features and was mechanically very interesting. This note describes why the engine was built and why the unique features were incorporated into the design. An animation of the engine is available.

• Research Technical Note: The Sentinel Steam Waggon at Riverside Museum The museum waggon was built 100 years ago, in 1916, during the First World War. This technical note describes some of the features of the waggon.

• Research Technical Note: Some Features of Dredgers – the Crane (Rock Cutter) Dredger. This note describes some features of the Buarque de Macedo a Lobnitz twin screw crane hopper dredger shown in use as a rock cutter (rock breaker).

• Research Technical Note: HMS Howe and the Walrus at Riverside Museum This technical note describes some of the features of the Supermarine Walrus seaplane.

• Research Technical Note: HMS Ocean and the Vampire at Riverside Museum This technical note describes some of the features of the de Havilland Vampire jetfighter.

• Research Technical Note: The Model Deltic Locomotive at Riverside Museum This technical note describes some of the features of the British Railways (British Rail), Class 55, diesel-electric Deltic locomotive.

• Research Technical Note: The Model SS Simla Engine at Riverside Museum. This note describes some features of the quarter scale model of the "Steeple Engine" for the single screw steamship Simla.
  
  
• Paper: Checking the Units of Engineering Calculations. This paper on dimensional analysis describes how to check the units of equations by cancellation.
