Correspondingly connected layers

Figure 4 a Two fully interconnected layers of PEs. b Two correspondingly connected layers of PEs. c Two round-robin-connected layers of PEs. d One layer of PEs fully connected to itself. 

Structure of cubic (left) and hexagonal (right) diamond. Top row connected layers as in a-As. Central row the same layers in projection perpendicular to the layers. Bottom unit cells when the light and dark atoms are different, this corresponds to the structures of zinc blende (sphalerite) and wurtzite, respectively... 

This structure formed a feed-forward network (Fig. 7.4) (4). Input nodes in the hrst layer corresponded to the independent variables characterizing each observation taken directly from the parameters of the experimental design. The input information was transmitted to layer 2 where the data were processed. Layer 2 consisted of numerous hidden nodes that connected layer 1 to layer 3. Layer 3 consisted of the output nodes, which were the mobilities of the analytes. 

Figure 6 A simple biassociative memory (BAM) network see Figure 5 for an explanation of the labels. The first BAMl layer has the same number of PEs as the input layer and is correspondingly connected to it the BAM2 layer has the same number of PEs as the output layer and is correspondingly connected to it. The two BAM layers are fully connected in both directions to each other.

The textile with embedded flexible solar cells overcomes the aforementioned technical problems. According to a first aspect, its subject matter is a reliable photovoltaic composite, employed in particular for solar protection, which includes at least one flexible photovoltaic panel and at least one textile panel on the outside face, on which the said photovoltaic panel is laminated by means of a first connecting layer. In a characteristic manner, in the direction transverse to that in which it is to be rolled and at any level of the photovoltaic panel, the said composite is of more-or-less constant thickness, including one or more reduced thickness zones, where the said reduced thickness corresponds to the thickness of the textile panel possibly covered with a film on its inside face. This particular arrangement is used to prevent the formation of folds in the composite, whether during the rolling operation or in the deployed position. 

There is a fundamental relationship between d-dimensional PCA and d + 1)-dimensional Ising spin models. The simplest way to make the connection is to think of the successive temporal layers of the PCA as successive hyper-planes of the next higher-dimensional spatial lattice. Because the PCA rules (at least the set of PCA rules that we will be dealing with) are (1) Markovian (i.e. the probability of a state at time t + T depends only on a set of states at time t, and (2) local, one can always define a Hamiltonian on the higher-dimensioned spatial lattice such that the thermodynamic weight of a configuration 5j,( is equal to the probability of a corresponding space-time history Si t). ... 

On the basis of crystallochemistry consideration and taking into account electron microscopy observations of the surface of crystals upon which some polymer was formed,99 Arlman and Cossee13 concluded that the active sites are located on crystal surfaces different from the basal (001) ones. In particular, these authors considered in detail active sites located on crystal surfaces parallel in the direction a — b of the unit cell defined as in Ref. 98. Figure 1.13 illustrates that, if we cut a TiCl3 layer parallel to the direction defined above, which corresponds to the line connecting two bridged Ti atoms, electroneutrality conditions impose that each Ti atom at the surface of the cut be bonded... 

In contrast to acidic electrolytes, chemical dissolution of a silicon electrode proceeds already at OCP in alkaline electrolytes. For cathodic potentials chemical dissolution competes with cathodic reactions, this commonly leads to a reduced dissolution rate and the formation of a slush layer under certain conditions [Pa2]. For potentials slightly anodic of OCP, electrochemical dissolution accompanies the chemical one and the dissolution rate is thereby enhanced [Pa6]. For anodic potentials above the passivation potential (PP), the formation of an anodic oxide, as in the case of acidic electrolytes, is observed. Such oxides show a much lower dissolution rate in alkaline solutions than the silicon substrate. As a result the electrode surface becomes passivated and the current density decreases to small values that correspond to the oxide etch rate. That the current density peaks at PP in Fig. 3.4 are in fact connected with the growth of a passivating oxide is proved using in situ ellipsometry [Pa2]. Passivation is independent of the type of cation. Organic compounds like hydrazin [Sul], for example, show a behavior similar to inorganic ones, like KOH [Pa8]. Because of the presence of a passivating oxide the current peak at PP is not observed for a reverse potential scan.
