¡Escribe tu texto aquí!¿What this maritime transportation brought to The ports? Ports Were born as protected places with a sea connection; this concept thru the Years produced an operational loss to vessels, up to a 30% of their useful Life, because they were obliged to stay at port docks for a long time, loading And discharging cargoes, causing high operational costs, affecting freights and Affecting final users, on the other hand, there was no other vision.

¿What originated this stagnant situation in the Ports? 1. Ports Were only considered to be an infrastructure for National Defense of countries.2. Ports did not enter to the transformation Of the port-maritime business, because most of the ports were state owned.3. They did not modernize

a structure is called statically indetermined if there is at least one load for which the external and internal reactions can be comptuted from the psequilibrium equation but not uniquely.

PS. A satically determined structure obtained from the original one by removing. N constraints and introducing the corresponding force/moments as redundants (Xi, i=1,2,...N)

Flexibility coeff. Aij is the displacement in the line of Xi due to Xgorritoj=1

Stiffness coefficients aij unbalanced force/moment at the ith artificial constraint due to a unit displacement applied at the jth artificial constraint

Load constants ai0 unbalanced force/moment at the ith artificial constraint due to the action of the given loads a0

c)Comment On the use polymers in construction giving examples of their use and describe The problems presented by the use of polymers in the event of a fire.

Answers 5 c):

Polymers are more common in the Construction industry than ever before and composite materials can offer good Strength to weight ratios as well as good levels of durability. GRP can offer alternative Bridge design options, particularly in remote areas where large section can be Flown in by helicopter and erected in shorter time periods. Other examples Include:

  • Window frames – UPVC

  • Rain-water goods – UPVC

  • Waste systems – UPVC / ABS

  • Glazing – Acrylics

  • Cold-water cisterns – Glass reinforced polyester

  • Cavity insulation – Polystyrene bats

  • Sealants are specified with a movement

PRINCIPLE

DESCRIPTION

LAYOUT

The interface should be a series of areas on the screen that are used consistently for different purposes

CONTENT AWARENESS

Users should always be aware of where they are in the system and what information is being displayed

AESHETICS

Interfaces should be functional inviting users through careful use of white space, colours and fonts. There is often a trade off between including enough white space to make the interface look pleasing without losing so much space that important information does not fit on the screen

USER EXPERIENCE

Although ease of use and ease of learning often lead to similar design decisions, there is sometimes a trade-off between the 2, novice users or infrequent users of software will prefer ease of learning,
