These are some essays and workups I've written for GURPSnet, the Traveller Mailing List, and others (including complete mathematical derivations, if appropriate):

    Berthing costs -- results of some research into real-world berthing and landing costs for commercial ships and aircraft
    Starship hulls -- a discussion of engineering requirements for ship structure and realistic hull size limitations in Traveller

    Deadstick glide ratios for air- and spacecraft created using GURPS Vehicles, 2d Ed. and especially GURPS Traveller
    Architectural standards for starship deckplans
    Jump point masking, where the jump point of the system's star blocks (masks) the jump point of the mainworld -- a significant hindrance to interstellar travel in GURPS Traveller
    First In statistics -- expected outcomes of world generation under GURPS Traveller: First In
    A process for generating more realistic Traveller sectors from Atlas of the Imperium data -- a simpler, 2D version of my JTAS article on the subject

    Trade classifications for GURPS Traveller -- a conversion of Traveller trade classification codes into GURPS Space terms
    The Nature of the Imperium -- a selection of quotes from canon

    Traveller population -- an estimate of the total population of Travellers within the Third Imperium
    Military Forces and Spending in Classic Traveller -- an analysis of the size of the Imperial military establishment and how much it costs to support
    Sectors and Sector Dukes -- a discussion of the limits of Imperial power
    Russians in Space -- an essay on the strategic position of the Imperium and historical models
    No Free Press -- an essay proposing the absence of the media as an effective Fourth Estate in Imperial politics, with a bonus Patron by way of illustration
