Unlike British models, all New Zealand Avengers from 1973 onwards had metric instruments.

Unlike I-95, I-495, DE 141, and the New Jersey Turnpike, which use a sequential exit system, or the Pennsylvania Turnpike, Atlantic City Expressway, and Garden State Parkway, which use a mileage-based system, the Korean War Veterans Memorial Highway segment of DE 1, along with the DE 9 and DE 12 interchanges, utilizes a kilometer-based system, in anticipation of a mid-1990s conversion of all measurements in the U. S. from the standard US measurement system to the metric system.

Unlike Euclidean space — where the dot product is positive definite — the metric gives each tangent space the structure of Minkowski space.

Unlike most universities which provide accommodation to faculty and staff on campus, due to a shortage of space, faculty housing is provided in the campus as well in nearby areas.

Unlike the physics of rigid bodies where the equations of motion describe the physical location of the rigid body, fluid dynamics describes the flow as a velocity field, i. e. a solution associates each point in space with a vector that represents the speed and direction of the flow at that point.

Unlike the other Star Trek TV shows, it took place on a space station instead of a starship, so as not to have two series with starships at the same time ( the starship USS Defiant was introduced in season 3, but the station remained the primary setting for the show ).

Unlike more recent concepts for space elevators, Tsiolkovsky's ( conceptual ) tower was a compression structure, rather than a tension ( or " tether ") structure.

Unlike tensors, the space of spinors cannot be built up in a unique and natural way from spatial vectors.

Unlike the AEC work, which was intended to study the reactor design itself, NERVA's goal was to produce a real engine that could be deployed on space missions.

Unlike on Earth, where heat can be transferred by convection to the atmosphere, in space, heat can be lost only by thermal radiation or by conduction to objects in physical contact with the exterior of the suit.

Unlike a graph, however, the number of semitones represented by a vertical step from a line to an adjacent space depends on the key, and the exact timing of the beginning of each note is not directly proportional to its horizontal position ; rather, exact timing is encoded by the musical symbol chosen for each note in addition to the tempo.

Unlike previous stations, the Soviet space station Mir had a modular design ; a core unit was launched, and additional modules, generally with a specific role, were later added to that.

: Unlike the science fiction Western, the space Western transposes traditional genre themes onto a space frontier backdrop, updating them with futuristic technologies.

Unlike novels, they are not divided into chapters, and are often intended to be read at a single sitting, as the short story, although white space is often used to divide the sections.

Unlike many colleges, St Catherines is no labyrinth of corridors and passages ; apart from the uncarpeted JCR, SCR and the office spaces in between, there is little indoor space in the college.

Unlike other CBDs, MIBC is being created as a single project, run by one designated company, and combines business activity, living space, retail trade, and entertainment in one single development.

Unlike those types however, the artists of this circle were highly influenced by the paintings of the impressionists, and thus while sharing the flatness, page layout and negative space of art nouveau and other decorative modes, much of Nabis art has a painterly, non-realistic look, with color palettes often reminding one of Cézanne and Gauguin.

Unlike the Seifert – van Kampen theorem for the fundamental group and the Excision theorem for singular homology and cohomology, there is no simple way to calculate the homotopy groups of a space by breaking it up into smaller spaces.

Unlike competing formats that have spaces in the casesette for the tape loading mechanism to be inserted, thus exposing the delicate magnetic tape surface, VCCs had a retractable sheath that covers such space.

Unlike a product space, principal bundles lack a preferred choice of identity cross-section ; they have no preferred analog of ( x, e ).

Unlike the true flight dynamics of space, those seen in Star Wars closely mirror the familiar dynamics of flying in Earth's atmosphere.

Unlike the zero volume assumed in a random walk calculation, all real polymers ' segments occupy space because of the van der Waals radii of their atoms, including bulky substituent groups that interfere with bond rotations.

Unlike the side tank, they did not go all the way down and there was space between the tank and the running plate.

Unlike the other two fictitious forces, the centrifugal force always points radially outward from the axis of rotation of the rotating frame, with magnitude, and unlike the Coriolis force in particular, it is independent of the motion of the particle in the rotating frame.

Unlike the other islands of the archipelago, Fuerteventura has a shelf which at some points goes up to 30 km, making it an ideal place to practice this sport.

Unlike the old code of points, there are two separate scores.

Unlike the d20 System and many other game systems, experience awards are in the form of character points, which have the same value as those used in character creation and can be applied directly to the character's abilities upon receipt.

Unlike the other Lagrangian points, would exist even in a non-rotating ( static or inertial ) system.

Unlike sodium, lead is mostly inert, so there is less risk of explosion or accident, but such large quantities of lead may be problematic from toxicology and disposal points of view.

Unlike the earlier Bohr model of the atom, however, the wave model describes electrons as " clouds " moving in orbitals, and their positions are represented by probability distributions rather than discrete points.

Unlike single-owner networks, the Internet is a series of exchange points interconnecting private networks.

Unlike the Giants, the Bills routinely used the no-huddle offense to storm down the field and score points very quickly.

Unlike barbed wire, which usually is available only as plain steel or galvanized, barbed tape is also manufactured in stainless steel, to prevent the points from rusting to bluntness.

Unlike in the " Sub Club " program, no other purchase is needed when redeeming points, and registered cards can be replaced if lost or stolen.

Unlike the concept of UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces.

: Unlike Shining Path, and like other armed Latin American organizations with which it maintained ties, the MRTA claimed responsibility for its actions, its members used uniforms or other identifiers to differentiate themselves from the civilian population, it abstained from attacking the unarmed population and at some points showed signs of being open to peace negotiations.

Unlike other woodwind instruments, in most wooden piccolos the tenon joint connecting the head to the body has two interference fit points which surround both the cork and metal side of the piccolo body joint.

Unlike the other villains, Marvin can be actually evil at most points, and not just daft.

Unlike other systems, which use " hit points " to tally damage, DQ has a two-tiered system of fatigue and endurance.

Unlike the critical points in, however, the critical points in h occur at local minima, so numerical optimization techniques can be used to find them.

Unlike in a conventional front loader, the lift arms in these machines are alongside the driver with the pivot points behind the driver's shoulders.

Unlike junction points, a symbolic link can also point to a file or remote Server Message Block ( SMB ) network path.

Unlike some home consumer models, industrial wireless access points can also act as a bridge, router, or a client.

Unlike French horns, the bell points to the left of the player instead of on the right.

Unlike the speculative proposal of ultraviolet fixed points, fixed points in the infrared are known to exist in asymptotically free theories, arising at two loops in the beta function providing that the fermion count N < sub > f </ sub > is large enough.
