The basic design remained unchanged for centuries, with the most significant changes being to the overall proportions, and a move from wooden stocks to those of iron.

The basic APC design was substantially expanded to an Infantry fighting vehicle ( IFV ) when properties of an armoured personnel carrier and a light tank were combined in one vehicle.

This style, called " tabbed " or " ridged ", used the same basic design as the original cartridges with the addition of two small tabs on the cartridge's underside to aid in removal.

There are four versions of the basic design, three of which are surface-to-air and one air-to-air.

These " extras " to the basic systematic search have been empirically shown to be essential for handling the large SAT instances that arise in electronic design automation ( EDA ).

While the complexity, size, construction, and general form of CPUs have changed enormously since 1950, it is notable that the basic design and function has not changed much at all.

Hardwired into a CPU's design is a list of basic operations it can perform, called an instruction set.

The way a CPU represents numbers is a design choice that affects the most basic ways in which the device functions.

Internal microcode execution in CISC processors, on the other hand, could be more or less pipelined depending on the particular design, and therefore more or less akin to the basic structure of RISC processors.

Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years.

Seeing the success of the LINC, in 1963 DEC took the basic logic design but stripped away the extensive A to D systems to produce the PDP-5.

Like the PDP-1 before it, the PDP-5 inspired a series of newer models based on the same basic design that would go on to be more famous than its parent.

This gave the company two years of unrestricted leadership, and eventually 1450 " straight eight " machines were produced before it was replaced by newer implementations of the same basic design.

A common way to carry out conceptual level design is to use the entity-relationship model ( ERM ) ( both the basic one, and with possible enhancement that it has gone over ), since it provides a straightforward, intuitive perception of an application's elements and semantics.

Dorst and Dijkhuis argued that " there are many ways of describing design processes " and discussed " two basic and fundamentally different ways ", both of which have several names.

Weapons include the " Mighty Foot " ( a basic kick attack ), a pistol, a shotgun, a chain gun ( similar in design to the Nordenfelt gun ), a rocket-propelled grenade launcher, pipe bombs, freeze-and shrink-rays, laser trip mines, and the rapid fire " Devastator " rocket launcher.

The new design used most of the basic PRISM concepts, but was re-tuned to allow VMS and VMS programs to run at reasonable speed with no conversion at all.

The designs of these forges have varied over time, but whether the fuel is coal, coke or charcoal the basic design has remained the same.

The development history is strictly incremental: while there have been many serious improvements, the basic design and architecture have not changed since the early versions.

The basic design of the current flag is specified by ; outlines the addition of new stars to represent new states.

Bel Geddes expounds upon his design in his book Magic Motorways, stating, “ Futurama is a large-scale model representing almost every type of terrain in America and illustrating how a motorway system may be laid down over the entire country – across mountains, over rivers and lakes, through cities and past towns – never deviating from a direct course and always adhering to the four basic principles of highway design: safety, comfort, speed and economy .” He had acknowledged this in the belief that “ A free-flowing movement of people and goods across our nation is a requirement of modern living and prosperity .”

Many building codes specify basic foundation design parameters for simple conditions, frequently varying by jurisdiction, but such design techniques are normally limited to certain types of construction and certain types of sites, and are frequently very conservative.

The pencil is one of the most basic graphic design tools.

The content is not the same, however: rather than individual security, it is the security and continuing existence of an `` ideological group '' -- those in the `` free world '' -- that is basic.

Whitehead contends that the human way of understanding existence as a unity of interlocking and interdependent processes which constitute each other and which cause each other to be and not to be is possible only because the basic form of such an understanding, for all its vagueness and tendency to mistake the detail, is initially given in the way man feels the world.

The basic premise of all mystery stories is that the distinction between good and bad coincides with the distinction between legal and illegal.

Furthermore, the network in Figure 3 is only the basic net through which other networks pertaining to logistics and the like are interlaced.

We are reminded, however, that freedom of thought and discussion, the unfettered exchange of ideas, is basic under our form of government.

The basic truth in the reactionary response is to be found in its realistic assumption of the primacy of the real over the ideational.

When the reactionary response is thus bolstered by an intellectual defense, the characteristics of that defense are explicable only in terms of the basic attitudes of unanalyzed reaction.

The maturity in this point of view lies in its recognition that no basic problem is ever solved without being clearly understood.

The strongest appeal of the Copernican formulation consisted in just this: ideally, the justification for dealing with special problems in particular ways is completely set out in the basic ' rules ' of the theory.

This of course was not true of the educated and sophisticated people we met, who loved their pets, but kindness is not a basic human instinct.

There is a clear relationship between their educational evaluations and their basic pattern of general values.

There is impressive consistency between specific occupational preferences and the student's basic conception of what is for him a good way of life.

Now the basic question to be asked in this situation is what motivates the manipulators, that is, what are their values??

Yet this basic condition of outlawry and anarchy is not the work of Katanga.

Mr. Richard Preston, executive director of the New Hampshire State Planning and Development Commission, in his remarks to the Governors Conference on Industrial Development at Providence on October 8, 1960, warned against the fallacy of attempting to attract industry solely to reduce the tax rate or to underwrite municipal services such as schools when he said: `` If this is the fundamental reason for a community's interest or if this is the basic approach, success if any will be difficult to obtain ''.

In still others which are barely on the threshold of the transition into modernity, the decade can bring significant progress in launching the slow process of developing their human resources and their basic services to the point where an expanded range of developmental activities is possible.

The basic mapping phase of the program has been completed and the inventory phase is scheduled for completion July 1, 1961.

Since the validity of all subsequent planning depends on the accuracy of the basic inventory information, great care is being taken that the inventory is as complete as possible.
