Null alleles complicate the interpretation of microsatellite allele frequencies and thus make estimates of relatedness faulty.

Null ciphers can also be used to hide ciphertext, as part of a more complex system.

* Null component: A Null component can make sure nothing happens in an IF-ELSE statement.

Null vector can refer to:

The Telepod technology was reverse-engineered by Tekla to create a force field generator so anyone can physically fight a Null Matter being without disintegrating on contact.

Even major injuries to his Darkhawk body can be repaired by switching back to his human form ; his Darkhawk body teleports back to its holding space on the Darkhawk ship in Null Space, where it can be repaired almost instantly.

As the Darkhawk body is no longer separate from Chris and does not teleport to Null Space when not in use, it is questionable whether it can be repaired as quickly as it once was.

Null objects occur with anaphoric Direct Objects, that is, those whose referents can be understood from the prior or ongoing discourse context as well as sufficiently salience in that context to be encoded pronominally.

* Null dust solutions: must correspond to a stress-energy tensor which can be interpreted as arising from incoherent electromagnetic radiation, without necessarily solving the Maxwell field equations on the given Lorentzian manifold,

Because of this, comparisons with Null can never result in either True or False, but always in a third logical result, Unknown.

However, certain operations on Null can return values if the value of Null is not relevant to the outcome of the operation.

Because it can be evaluated as a series of equality comparison conditions, a simple expression cannot check for the existence of Null directly.

Null congruences are also important, particularly null geodesic congruences, which can be interpreted as a family of freely propagating light rays.

This incident led to German Admiral Dönitz issuing the Triton Null signal on 17 September 1942, which came to be known as the " Laconia Order "; the signal forbade submarine commanders from rescuing survivors from torpedoed ships.

* Which suit, if any, will be the trump suit, or if a special type of contract ( such as Null ) will be played

Null and filter approaches must be used with bistatic radar, like semi-active radar homing, for practical reasons because side-lobes from the illumination radar will illuminate the environment in addition to the main-lobe illumination on the target.

Codd indicated in his 1990 book The Relational Model for Database Management, Version 2 that the single Null mandated by the SQL standard was inadequate, and should be replaced by two separate Null-type markers to indicate the reason why data is missing.

For example, if overloaded functions are supported by the RDBMS, SQL might not be able to automatically resolve to the correct function without knowing the data types of all parameters, including those for which Null is passed.

SELECT CASE i WHEN NULL THEN ' Is Null ' -- This will never be returned

Because the expression evaluates to Unknown no matter what value column i contains ( even if it contains Null ), the string will never be returned.

SELECT CASE WHEN i IS NULL THEN ' Null Result ' -- This will be returned when i is NULL

The following example table with a check constraint will prohibit any integer values from being inserted into column i, but will allow Null to be inserted since the result of the check will always evaluate to Unknown for Nulls.

The result of the code above will always be the message since the comparisons with Null always evaluate to Unknown.

If particular Weyl components vanish, then and / or are said to be Weyl-Aligned Null Directions ( WANDs ).

* Null ( mathematics ), a zero value in several branches of mathematics

Following several years in the Japanese noise rock scene that included collaborations with Merzbow and Hanatarashi, experimental noise rock guitarist and electronic programmer KK Null formed Zeni Geva in 1987 with guitarist Fumiyoshi Suzuki ( also known as " NP "), vocalist Elle, and drummer Ikuo Taketani of the Japanese experimental groups The Boredoms and Hanatarashi.

Null remained prolific via solo and collaborative releases, while Tabata worked with several projects, including Acid Mothers Temple.

Null set was once a common synonym for " empty set ", but is now a technical term in measure theory.

Amidst the devastation of the Stunde Null year of 1945 cinema attendance was unsurprisingly down to a fraction of its wartime heights, but already by the end of the decade it had reached levels that exceeded the pre-war period.

The Null Stern Hotel in Teufen, Appenzellerland, Switzerland and the Concrete Mushrooms in Albania are former nuclear bunkers transformed into hotels.

Carroll's 1987 book Liber Null & Psychonaut is considered one of the defining works of the chaos magic movement.

The results of the data analysis in confirming or failing to reject the Null hypothesis are then reported and evaluated.

Null space of the Gram matrix is given by vectors for which.

Another feature is the NET ( Null End Tag ) construction:, which is structurally equivalent to.

Christopher Null of Filmcritic. com said, " In our collective consciousness, Leatherface and his chainsaw have become as iconic as Freddy and his razors or Jason and his hockey mask.

Because of the significance of this distinction, gender changers and null modems for serial communications are typically labeled with the words Gender Changer or Null Modem to clarify the internal wiring.

# Null ( A ) always contains the zero vector, since A0 = 0.

Christopher Null believes, " the send-up of Mussolini-types doesn't quite pan out.

Other key Japanese noise artists that contributed to this upsurge of activity include Hijokaidan, Boredoms, C. C. C. C., Incapacitants, KK Null, Yamazaki Maso's Masonna, Solmania, K2, The Gerogerigegege and Hanatarash.

* Null reference device: Does nothing.
