Object-Oriented Software Construction contains a detailed treatment of the concepts and theory of the object technology that led to Eiffel's design.

Eiffel's most important contribution to software engineering is design by contract ( DbC ), in which assertions, preconditions, postconditions, and class invariants are employed to help ensure program correctness without sacrificing efficiency.

Under Eiffel's design, a software text should be able to reproduce its design documentation from the text itself, using a formalized implementation of the " Abstract Data Type ".

The usual pattern for building a railway terminus was to conceal the metal structure behind an elaborate facade: Eiffel's design for Budapest used the metal structure as the centrepiece of the building, flanked on either side by conventional stone and brick-clad structures housing administrative offices.

The enhanced idea gained Eiffel's support for the project, and he bought the rights to the patent on the design which Koechlin, Nougier and Sauvestre had taken out.

A budget for the Exposition was passed and on 1 May Lockroy announced an alteration to the terms of the open competition which was being held for a centerpiece for the exposition, which effectively made the choice of Eiffel's design a foregone conclusion: all entries had to include a study for a four-sided metal tower on the Champ de Mars.

In the early 1990s Angela Gardner, an American architectural student who visited Santa Rosalía and examined the church, came to a hypothesis that the church design was from a different architect, belonging to the House of Duclo rather than Eiffel's firm, to the dismay of the locals, who believe this would diminish the appreciation of the building.

Eiffel's simplicity is intended to promote simple, extensible, reusable, and reliable answers to computing problems.

In the group of islands in the “ middle ” of the Kvarken region, in Swedish called Valsörarna – Finnish Valassaaret, is a 36 meter high lighthouse designed by Henry LePaute who worked for Gustave Eiffel's engineering bureau.

Eiffel's proposal was for a bridge whose deck was supported by five iron piers, with the abutments of the pair on the river bank also bearing a central supporting arch.

On 12 May a commission was set up to examine Eiffel's scheme and its rivals and on 12 June it presented its decision, which was that only Eiffel's proposal met their requirements.

Eiffel's control structures are strict in enforcing structured programming: every block has exactly one entry and exactly one exit.

One of these, a pavilion for the Paris Gas Company, was Eiffel's first collaboration with Stephen Sauvestre, who was later to become the head of the company's architectural office.

Visitors can peek inside port windows and see mannequins of Edison and Eiffel ( and Eiffel's daughter, posed with the phonograph ), the tableau commemorating their fabled meeting of September 10, 1899 in which, over cigars and cognac, they discussed possible joint projects and their participation in Jules Verne's " smoking club " for avowed futurists, dubbed Plus Ultra.

The structure was famous for its era, competing with Gustave Eiffel's engineering works in France — the Garabit viaduct and the Eiffel Tower in Paris.

Eiffel's standard data types, such as, and, are all themselves classes.

The Bordeaux bridge, Eiffel's first major work.

Eiffel's principal job was to draw up the arch girders of the Galerie des Machines.

Eiffel's reputation was badly damaged when he was implicated in the financial and political scandal which followed.

Yet within this limitation there is an astonishing variety: design as intricate as that in the carpet or miniature, with the melodic line like the painted or woven line often flowing into an arabesque.

The design is determined emotionally: `` I must reach into myself for the spring that will send me catapulting recklessly into the chaos of event with which the dance confronts me ''.

The answers derived by these means may determine not only the temporal organization of the dance but also its spatial design, special slips designating the location on the stage where the movement is to be performed.

The mystique of sex, combined with marijuana and jazz, is intended to provide a design for living.

I refer to the notion that the structure of society is a microcosm of the cosmic design and that history conforms to patterns of justice and chastisement as if it were a morality play set in motion by the gods for our instruction.

The work is executed in England ( by hand ) and can be worked in any desired design and color.

American technology in engine and hull design is largely responsible for the plentiful interest in American boating.

The design of a mechanical interlocking frame is much like a mechanical puzzle, but once understood, the principles can be applied to any track and signal arrangement.

Previously known as Jefferson Arms, Kodiak has given this 11-shot hammerless job an exceptionally fine stock design, and the 260 is the first autoloader to handle

This design is hard to beat for timber hunting or for packing in a saddle scabbard.

Stock design is excellent, and this model is a good first gun.

If the background of design is too smooth, or you wish to create a wood-grained effect, it may be added at this time with a dull tool such as the handle of a fine paintbrush.

While assembled lid is still on design head, gently but firmly press it on plaster board.

The idea behind our design is modular units, or panelization.

What I have observed time and time again is a process of integration, integration that begins as abstract design and gradually takes on recognizable form ; ;

Just because a tree or other object appears in a certain spot is absolutely no reason to place it in the same position in the painting, unless the position serves the design of the whole composition.

`` Speed in painting a picture is valid only when it imparts spontaneity and crispness, but unless the artist has lots of experience so that he can control rapid execution, he would do well to take these first sketches and soberly reorder their design to achieve a unified composition.

It is possible, of course, to work on extant or projected buildings where either architect or owner will explain their necessities so that the student may get `` the feel '' of real interior design demands.

Considerable specialization in teaching subjects such as architecture, furniture design, textiles and color is also desirable.

It is only fair to demand that teachers of courses in English, history, psychology and so on be as well informed in matters of art, especially interior design, as are the art teachers educated in the academic subjects.

Harold E. Strang, expert in switchgear design, for a long period vp & gm of the Measurements & Industrial Products Division, and who currently, approaching retirement, is vice-president and consulting engineer in the Switchgear & Control Division.

One of the most significant advancements in design of plastics signs is the so-called trans-illuminated billboard, now being produced by several large sign manufacturers such as Advance Neon Sign Co., Los Angeles, and Industrial Electric Inc., New Orleans, La..

Perhaps the best way to indicate the versatility of design that characterizes the use of plastics in signs and displays would be to look at what is happening in only one of the areas in this complex field -- changeable signs.

In this design the anode holder is water cooled and the heat losses by conduction from the anode were determined by measuring the temperature rise of the coolant.
