Function shared object

Unlike the procedural languages discussed above, C language functions are compiled separately. The code itself is not included in the SQL create function command. Instead, the create function command refers to a compiled object such as shared object (.so) file located in some directory on the server running the RDBMS. For example, the CHORD oe smiles function is defined as follows. 

This defines the SQL function oe smiles, which is realized by calling the C function oe anysmiles in the shared object file gnova.so. The definition of the input arguments and return values is done in the same way as for a function written in any other procedural language. 

In functions written in other languages, the code appears in the create command, whether it is written in SQL, plpgsql, plperl, or plpython. For C language functions, the name of the shared object, here bits.so, and the name of the c function, here nbits set are named in the create command. 

The mathematical formulation that addresses the above two problems share the same constraints, the only difference is in the solution procedure and the objective functions. 

In the beginning, functionalization reactions were applied to fullerenes [1], later to CNTs [4,3], and recently to graphene [5]. Although both functionalization approaches have clear differences, they share the same intrinsic objective the creation of defects or doping within the surface of the carbon nanostructures in order to facilitate the interactions between the matrix and the filler. 

Hydrocracking and hydroisomerization are related bond breaking and rearrangement processes which rely on the use of dual function catalysts operating under high hydrogen pressure to achieve their objectives. In fact, they share the same fundamental mechanistic steps and differ mainly in the degree to which some... 

The ethical implications also cannot be ignored. Any research that uses human volunteers must examine its motives and methods to make certain that human beings are not being manipulated like objects for purposes they do not understand or share. But in research with powerful mental chemicals that may influence the most cherished human functions and values, the ethical problem is even more acute. The mystical experience, historically, has filled man with wondrous awe... 

The objective function of a supply network design model can either minimize costs or maximize profits. In practice the production function is often required to assume that all forecasted demands have to be met. In this constellation cost minimization and profit maximization lead to identical results and consequently cost minimization models are used. From an economic perspective this simplification can be justified in cases where a high share of fixed costs allows the assumption that any product sale con-... 

It is important to note that the use of Logsdon et al. s objective function will not change the number of plates and operating policies if the mixtures were to share the column by a certain fraction of time (the profit function of Logsdon et al. does not include the allocation time). However, for different allocation time to each mixture, the total number of batches for each separation, individual and total yearly profit, etc. can be evaluated by using the results presented in Table 7.7. These are summarised in Table 7.8. Comparison of the results in Table 7.4 and 7.8 clearly... 

For the derivation of appropriate fuzzy membership functions for the electronic densities of functional groups, first we take each individual functional group Fj, with its share PfiC1 ) °f the complete electron density of molecule X, and consider this share as a separate, individual object in the absence of all other functional groups of... 

The addition of a second spatial dimension to the line imaging experiment yields the technique most commonly referred to simply as Raman imaging (1,2). Although several approaches to the problem are available commercially, they share a common objective of providing Raman intensities as a function of Av, x, y, and sometimes depth (z). To illustrate an example of two-dimensional Raman imaging. Figure 11.17 shows both a Raman image... 

PostgreSQL is generally referred to as an Object Relational Database Management System (ORDBMS). The use of the word object implies objects in the sense of an object-oriented computer language. While not intended to be fully object-oriented in the same sense as a computer language, an ORDBMS shares the essential aspects of objects. These include composite data types, methods (functions), and inheritance.
