Mixing Strategy

The aim of the mixing air conditioning strategy is to provide uniform conditions throughout the air-conditioned room. 

The contaminant removal and temperature effectiveness in the mixing strategy are equal to 1. In practical installations incomplete mixing in the room and unfavorable temperature gradient and location of the exhaust openings in relation to air supply may, however, cause short-circuiting of the supply air into the exhaust openings and the efficiency may remain below 1.

Air jets are used to create enough air movement inside the room to circulate and mix the whole room air. This strategy is often called dilution ventilation as the contaminants created inside the room are mixed into the whole room volume thus reducing the local peak concentrations. 

The room airflows are controlled mainly by the supply or/ md circulation air jets using, for example, concentrated jets, ceiling air supply, or high-impulse nozzle systems. Examples of different methods are illustrated in Fig. 8.14.

Other important aspects include the effect of temperature (via activation energy) and mixing, particularly for multiphase reactions. Both of these can impact on selectivity and thus can be improved in operating continuously using the inherent benefits of heat transfer area and mixing strategies discussed previously. 

In addition, SPOS can easily be automated using appropriate robotics for both filtration and evaporation of the volatiles from the reaction mixture to obtain the cleaved product. Furthermore, SPOS can be applied to the powerful split-and-mix strategy, which has proved to be an important tool in combinatorial chemistry [7]. 

I hypothesised (Baker and Beilis 1995 Baker 1996) that the within-population frequency distribution of testes size reflects a balanced polymorphism. In this hypothesis, men with larger testes were programmed to spend less time with partners, ejaculate often, and expose their sperm more often to sperm competition. Men with smaller testes were programmed to invest more in mate guarding and only infrequently to expose their sperm to competition. Between the two extremes, the intermediate men were programmed to pursue a more mixed strategy. 

This dendritic support (1) was used to generate a library of indole derivatives with three centers of diversity following the Fischer protocol and the split and mix strategy. One example of this sequence is outlined in Scheme 7.1. 

The best strategy on how to spend resources of time and money most efficiently can be considered a problem in operations research, under the topic of optimal resource allocation. The best way to use the limited resources of money and time effectively may be a mixed strategy, with some guided and some random searches. 

Mixing strategies for droplets formed at low aspect ratio/split and merge mixing... 

M 14] [P 14] Splitting of droplets can only occur at aspect ratios <0.2 (for definition see Effect of aspect ratio) [29]. Since this is an important microfluidic action, it was worth finding suitable novel mixing strategies to overcome this limitation. 

The double side-band receiver noise temperature has been measured for a variety of receivers based on several mixing strategies. An InSb hot-electron bolometer operated as a mixer was found to have a double side-band receiver noise temperature = 300 K at 220 GHz (Blaney, 1980). This corresponds to an NEP = 10 W/ /Hz referred to a predetection bandwidth of 100 GHz. The single frequency performance of mixer-based receivers does not generally match this performance, however (Boucher et al., 1993). 

All these sequences include a (90°) preparation pulse which flips the magnetization of the spin system into the xy plane. The evolution period is then the period of free precession of the spin system in the xy plane, in the Hahn spin echo experiment (Fig. 6). The almost infinite variations in the mixing strategies serve the purpose of bringing out those features of the correlated motions in the system of coupled spins which one wishes to observe. 

As indicated in Fig. 1. lb, the individual matchers may either be executed sequentially, independently (in parallel), or in some mixed fashion. In the sequential approach, the matchers are not executed independently, but the results of initial matchers are used as input by subsequent matchers. A common strategy, e.g., used in Cupid (Madhavan et al. 2001), is to first execute a linguistic matcher to compare the names of schema elements and then use the obtained similarities as input for structure-based matching. In the parallel matcher strategy, individual matchers are autonomous and can be independently executed from other matchers. This supports a high flexibility to select matchers for execution and combination. Furthermore, these matchers may also physically be executed in parallel, e.g., on multicore or multiserver hardware. On the other hand, the autonomy of individual matchers may introduce redundant computations, e.g., of name similarities to be used for structural matching. The mixed strategy combines sequential and parallel matcher execution and is thus most complex.
