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.

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.

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 Office of Business Economics ( OBE ) of the U.S. Department of Commerce provides basic measures of the national economy and current analysis of short-run changes in the economic situation and business outlook.

Much of the current work in cosmology includes understanding how galaxies form in the context of the Big Bang, understanding the physics of the Universe at earlier and earlier times, and reconciling observations with the basic theory.

Ohm's law is a basic law of circuit theory, stating that the current passing through a resistance is directly proportional to the potential difference across it.

There have been three Grey Ghost Press editions, the most current being the Fudge 10th Anniversary Edition, which includes several suggested rules systems for common RPG elements and an example basic fantasy " build " of the game.

The conventional SI system of units is based on seven basic dimensional quantities, namely distance, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity.

Somatic gene therapy represents the mainstream line of current basic and clinical research, where the therapeutic DNA transgene ( either integrated in the genome or as an external episome or plasmid ) is used to treat a disease in an individual.

Inductors are one of the basic components used in electronics where current and voltage change with time, due to the ability of inductors to delay and reshape alternating currents.

The current worldview has it that everything is made of matter, and everything can be reduced to the elementary particles of matter, the basic constituents — building blocks — of matter.

To this end, he compares George Orwell's Coming Up for Air with Frederik Pohl and C. M. Kornbluth's The Space Merchants and concludes that the basic building block and distinguishing feature of a science fiction novel is the presence of the novum, a term Darko Suvin adapts from Ernst Bloch and defines as " a discrete piece of information recognizable as not-true, but also as not-unlike-true, not-flatly-( and in the current state of knowledge ) impossible ".

This is a chart of trend of regional gross value added of Suffolk at current basic prices published ( pp. 240 – 253 ) by Office for National Statistics with figures in millions of British Pounds Sterling.

The current notion of state sovereignty is often traced back to the Peace of Westphalia ( 1648 ), which, in relation to states, codified the basic principles:

The ideal model not only neglects basic physics factors in terms of primary current required to establish a magnetic field in the core and the contribution to the field due to current in the secondary circuit but also assumes a core of negligible reluctance with two windings of zero resistance.

The basic invention involves passing an electric current through a bath of alumina dissolved in cryolite, which results in a puddle of aluminum forming in the bottom of the retort.

The anti-psychiatry movement says that the specific definitions of, or criteria for, hundreds of current psychiatric diagnoses or disorders are vague and arbitrary, leaving too much room for opinions and interpretations to meet basic scientific standards.

The basic Chevrolet small-block V-8 design has remained in continuous production since its debut in 1955, longer than any other mass-produced engine in the world, although current versions share few if any parts interchangeable with the original.

The basic sensitivity of a meter might be, for instance, 100 microamperes full scale ( with a voltage drop of, say, 50 millivolts at full current ).

The product of the basic full-scale deflection current of the movement, and the sum of the series resistance and the movement's own resistance, gives the full-scale voltage of the range.

Higher DC voltage ranges, current, resistance, AC and other ranges will usually have a lower accuracy than the basic DC volts figure.

Since the basic indicator system in either an analog or digital meter responds to DC only, a multimeter includes an AC to DC conversion circuit for making alternating current measurements.

In a basic analog multimeter the current to deflect the coil and pointer is drawn from the circuit being measured ; it is usually an advantage to minimize the current drawn from the circuit.

Some basic circuits can be designed by assuming that the emitter – base voltage is approximately constant, and that collector current is beta times the base current.
