... The choice of which type of electricity is called "positive" and which "negative" was made around 1750 by Ben Franklin, early American scientist and man of many talents (the stamp on the left commemorates his role as first US postmaster--and colonial postmaster before that). ... Franklin knew of two types of electric charge, depending on the material one rubbed. ... Later, when electric batteries were discovered, scientists naturally assigned the direction of the flow of current to be from (+) to (-...

... I am developing an Informed Prefetching and Caching system as part of the kernel in which it is very important that the memory assigned to hold the data does not get swapped to disk. Without any thought to swapping I used vmalloc() to assign memory to the data structures of the Informed prefetching system. ... I later realized that most probably the pages assigned using vmalloc() were getting swapped to the disk and when I referenced them, they were brought from the disk rather than memory. ...

. The process identity (PID) number for this process. As each process is begun it is assigned a process number. Each system has a maximum value for the PID number. When this is reached the PID numbering is started again. This number is used to kill the process .

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

... Any events that have obtained a negative charge sum PI (see above) and a get a positive total charge PI assigned; if these have then they get a positive total charge PI assigned and the INVALID_PATTERN bit set in the FLAG column. In the implementation of version 6.30.3 (and earlier) single events close to edges or bad pixels do not get PATTERN=0 but get the bit set, too, and thus PATTERN=128 (Sect. ... All (apparent) singles at the CCD edges, readout window, or close to bad pixels get PATTERN=128. ...

In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ... Work of the resident. ... Any change of the list of target processes or arguments of resident function results in activation of the resident and repeated collection of information in the target worlds. ...

... Satellites of the planets are assigned a provisional designation (indicating year of discovery) by the Central Bureau for Astronomical Telegrams ( CBAT ) upon satisfactory demonstration of the existence of a new object. ... In the past, Comets were first given a provisional designation, consisting of the year and a lowercase letter indicating the order of discovery in the year (e.g., 1994a was the first comet discovered or recovered in 1994, 1994b the second, etc.) ...

... First of all, you can obtain a map of the final coordinates of your objects and guide stars by using the command: PLOT/OPTOPUS [table] [label] [EW_flag] , . where [table] is the table output by REFRACTION/OPTOPUS . ... In order to avoid object misidentifications at a later stage, and for a cross identification between object identifiers and hole numbers, it is recommended to bring a printout of the table output created by the command REFRACTION/OPTOPUS to the telescope. ...

Describes how spatial region boundaries are handled. The golden rule for spatial region filtering was first enunciated by Leon VanSpeybroeck in 1986: . ... With this in mind, the rules for determining whether a boundary image pixel or table row are assigned to a region are defined below. For image filtering, pixels whose center is inside the boundary are included. ... That is, an row is inside the boundary without regard to its integerized pixel value. ...
