Pointer system

State driver licensing officials query the NDR to determine if an individual s license or privilege has been withdrawn by any other state. Other authorized users have access to the NDR for transportation safety purposes. All 50 states and the District of Columbia participate in the NDR. The system is also referred to as the Problem Driver Pointer System (PDPS). 

The first part of the method involves sorting all the atoms into their appropriate cells. This sorting is rapid, and may be perfonned at every step. Then, within the force routine, pointers are used to scan tlirough the contents of cells, and calculate pair forces. This approach is very efficient for large systems with short-range forces. A certain amount of unnecessary work is done because the search region is cubic, not (as for the Verlet list) spherical. 

This can be checked with the help of a phase sequence indicator. This is a simple instrument that houses a small 30 motor, which rotates a pointer connected to the motor through a gearbox. The direction of rotation of the pointer will determine the phase. sequence of the system. 

The movement of the pointer may be observed with respect to a reference pointer which is sealed into the jacket from above. The pointer P can also be made to move a glass lever system which magnifies the movement (S. G. Foord, 1934). 

In the direct-reading instruments the emf of the cell is led through an (operational) amplifier across a standard high resistor yielding a current that is measured by a milliammeter calibrated to be read in pH units or millovolts. So, while the null-point system provides a truly potentiometric (non-faradaic) measurement where the off-balance adjustment remains limited to an interrupted temporary current draw-off, the direct-reading system represents an amperometric measurement where a continuous steady-state current draw-off takes place as long as the meter is switched on. In fact, the latter is a deflection method as a pointer indicates the pH units or millivolts by its deflection on the meter scale. 

This is an abstract model of the state of the whole System, and says nothing about its construction — whether it is distributed or centralised, whether the links are database keys or pointers, whether the types can be found in the implementation as individual classes. These matters are all left to the design phase a distributed object implementation, or a server-based one with remote screen-control clients would both be equally valid choices. 

Program each system-level action. For each action specified for the component as a whole, design how its spec will be fulfilled by a collaboration of objects within the component. Make the starting assumption that the classes and pointers available are the types and associations from the component spec s static model. 

In addition to the fully automated 670 system, Metrohm also supply simpler units with more limited facilities which nevertheless are suitable for more simple titrations. Thus the model 682 titroprocessor is recommended for routine titrations with automatic equivalence pointer cognition or to preset end points. The 686 titroprocessor is a lower-cost version of the above instrument, again with automatic equivalence point recognition and titration to preset end points. 

When a novel homology domain has been discovered, it is possible to store the corresponding domain descriptor (profile or HMM) in a number of dedicated domain databases, which can be used to analyze newly identified sequences for their domain content [9, 10]. Several competing domain- and motif-databases exist, including PROSITE, PFAM, SMART, and Superfam, which contain descriptors for most, if not all, of the known domains involved in the ubiquitin system [11-14]. Recently, a new meta-database named INTERPRO has been established, which tries to combine the descriptors of several domain databases under a single user interface [15]. Pointers to the very useful search engines of the domain databases are provided in Table 12.1. 

A side effect of this approach is the consistency and completeness checking which is performed at building time when the rule pointers are being set up. Errors and oversights are caught at this stage and corrected before the iterative development cycle is continued. Most expert system approaches do not support error... 

By comparison with studies of complex formation in aqueous solution, the gaseous transport of coordination compounds in geochemical systems has received scant attention despite many pointers to the possibility, especially concerning volcanic emanations, arising from metallurgical processes. In Section 64.2 reference was made to a number of halides associated with fumarolic...
