The dynamic model calculations are done in a two phase process. In the first phase, the solids stream dynamic equations are integrated for the reactor while keeping gas stream conditions constant. When necessary, intermediate gas stream values are obtained by interpolation between storage nodes. These calculations proceed down the reactor for the distance and time method of lines, and back up the reactor for the method of characteristics. In the second phase, the gas stream steady state equations are integrated from the bottom to the top of the reactor while keeping the solids stream conditions constant. Intermediate solids stream values are obtained by interpolation between storage nodes. [Pg.344]

Before the metal-organic CVD (MOCVD) process of the BST film is discussed, the reasons for using the CVD process, despite its difficulties should be described. The storage node size of the capacitors in the current state-of-the-art DRAMs is about 0.15 x 0.35 x 1.0 pm with minimum spacing of about 0.15 pm between the nodes when the dielectric layer is a SiO/SijN bi-layer or Ta O, and the electrode materials are poly-Si. Here 1 pm is the height of the nodes. Even smaller lateral dimensions are expected when DRAMs use a BST thin film as the capacitor dielectric layer. Even though the BST films have a much smaller t value, which... [Pg.206]

Another requirement for the CVD barrier layer comes from the so called buried barrier scheme, as shown in Figure 24c. As the storage node size decreases to about 100 nm, oxidation of the barrier primarily proceeds from the side wall area rather than the interface with the storage electrodes. One way to alleviate this problem is to bury the barrier layer in the... [Pg.233]

MOCVD is the process of choice for the deposition of BST films considering the requirement of conformal deposition on three dimensional storage nodes. The precursors and hardware systems for MOCVD were discussed keeping in mind the mass production compatibility of the processes. The quite different chemical properties of group II (Ba and... [Pg.238]

Demons and Variables. ALEX provides a three-tiered knowledge representation structure of contexts, demons, and variables. Contexts are top-level structures that isolate individual major areas of the problem under analysis. Demons are the central knowledge representation structure they are essentially frame-based information storage nodes with slots both to hold information on the content of the demon and to reflect the impact of one or more variables on the status of the demon. Variables may hold user-input, default, or calculated information. [Pg.138]

Storage nodes All ports of a storage node are storage ports, which means that one of the port variables has to be integrated with respect to time before it plays a role in the constitutive relation of the node or obtained by differentiation with respect to time from a result of the constitutive relation. If the flow variable is integrated with respect to time into a so-called g-type state variable or if the flow variable is obtained by differentiation with respect to time of the constitutive relation, that is, a function of the effort, the port is called a C-type port (or -type port). If the effort variable is integrated with respect to time into a so-called p-type state variable or the effort is obtained by differentiation with respect to time of the con-... [Pg.12]

There is a preference for a particular causality. For example, in case there is a preference for integration over differentiation with respect to time, the ports of the storage nodes, (M)C and (M)I, may be given a preferred causality, viz., effort-out (C) and flow-out (I), respectively. This will turn out to be the most common preferred causality later, when a causality assignment algorithm is discussed aimed at generating a set of differential equations that is in an optimal form for numerical simulation. [Pg.23]

The overall model for this scenario involves 5614 constraints, 1132 continuous 280 binary variables. Three major iterations with an average of 1200 nodes in the branch and bound search tree were required in the solution. The objective value of 1560 kg, which corresponds to 33.89% reduction in freshwater requirement, was obtained in 60.24 CPU seconds. An equivalent of this scenario, without reusable water storage, i.e. scenario 2, resulted in 13% reduction in fresh water. Figure 4.12 shows the water recycle/reuse network corresponding to this solution. [Pg.93]

Table 4.4 is the summary of the mathematical model and the results obtained for the case study. The model for scenario 1 involves 637 constraints, 245 continuous and 42 binary variables. Seventy nodes were explored in the branch and bound algorithm. The model was solved in 1.61 CPU seconds, yielding an objective value (profit) of 1.61 million over the time horizon of interest, i.e. 6 h. This objective is concomitant with the production of 850 t of product and utilization of 210 t of freshwater. Ignoring any possibility for water reuse/recycle, whilst targeting the same product quantity would result in 390 t of freshwater utilization. Therefore, exploitation of water reuse/recycle opportunities results in more than 46% savings in freshwater utilization, in the absence of central reusable water storage. The water network to achieve the target is shown in Fig. 4.14. [Pg.95]

Deployment of software is shown here against this physical model, with different software components shown on different hardware nodes for example, the software components in the four-tier system are shown in Figure 12.5. Note that software component requirements, such as memory and storage space, can be modeled as attributes and matched against the corresponding attributes of the hardware. If needed, you can also explicitly specify the effect of actions, such as node failures (failover requirements) or network load, against such a model. [Pg.509]

Genetic mannosidosis has been described in man, Angus cattle and Murray Gray cattle, and is characterized by a deficiency of a-mannosidase leading to storage of excess mannose-rich oligosaccharides in lysosomes. Pathologically, there is vacuolation of reticuloendothelial cells in the liver and lymph nodes, pancreatic exocrine cells, and neurons. Affected cattle are ataxic, uncoordinated, fail to thrive, and die in the first year of life. [Pg.46]

Increases in processor speeds and storage capacity allowed these system to acquire and process data rapidly. Many fourth-generation systems became nodes in laboratory computer UMS networks. They communicate with host computers to receive instructions for analyses and for transferring results. Programs and values of parameters for specific analytical methods can be stored in memory and recalled by the analyst as needed. While the analyst found interaction with these systems easier, he or she became further removed from the system components and often more dependent on the vendor s software. Tailoring requirements to individual user requirements was often not viable with this approach. [Pg.232]

Factors which tend to decrease bioavailability of pyridoxine include (1) Administration of isoniazid (2) loss in cooking (estimated at 30-45%)—vitamin is water-soluble, (3) diuresis and gastrointestinal diseases (4) irradiation. Availability can be increased by stimulating intestinal bacterial production (very small amount), and storage in liver. The target tissues of Be are nervous tissue, liver, lymph nodes, and muscle tissue. Storage is by muscle phosphorylase (skeletal muscle—small amount). It is estimated that 57% of the vitamin ingested per day is excreted. The vitamin exerts only limited toxicity for humans. [Pg.1701]
