Gauss and Codazzi equations for a submanifold N in a Banach manifold M are obtained in [1]. If in the capacity of the manifold M, we consider a Hilbert manifold E, then Gauss and Codazzi equations can make more precise. In this paper, the mentioned equations are established for submanifolds in Hilbert ones. Also when codim N=1 we derive the previous equations for a hyper surfaces in a Hilbert manifold.

In this work a novel wavelet-fuzzy logic approach to feature extraction and damage classification in structural health monitoring is proposed. The proposed method combines the effectiveness of the Wavelet Packet Transform (WPT) as a tool for feature extraction and the capabilities of fuzzy sets to model vagueness and uncertainty. Two stages of operation are considered: pattern training and health monitoring. Pattern training is concerned with the determination of fuzzy sets based baseline patterns representing health condition states for which training data are available. Health monitoring is concerned with the classification of new data into the different structural health states. This classification problem is solved based on determining degrees of membership values to each one of the previously defined fuzzy patterns. In order to demonstrate the effectiveness and viability of the proposed approach, the method was applied to data collected from an experiment involving repeatedly impact excitations of an aluminium cantilever beam. Different damage cases in the beam where emulated by adding a lumped mass at different locations. The measured vibration response data provided by six accelerometers were analysed. Results show that the method is effective in classifying the different damage cases. Therefore, the proposed method has potential for structural health monitoring applications.

The purpose of this paper is to introduce a new compound optimum design called DAT. The proposed design combines D-optimality, A-optimality and T-optimality together. The importance of DAT optimality criteria comes from its flexibility in parameter estimation, minimizing the average variance and model discrimination. Part of this flexibility results from the algorithms that can be derived using the equivalence theorem that introduced in this paper. An extension of DAT optimality criteria was also introduced.

Guts of Crassostrea gigas, C. corteziensis, and Atrina maura were screened for bacilli and lactic acid bacteria with probiotic properties for bivalve mollusks. Characterization of the isolates included Gram stain, morphology, cell arrangement, catalase and hemolytic activity, hydrophobicity, autoaggregation, coaggregation against Vibrio sinaloensis VHPC23, biofilm formation, counting of colony forming units (CFU), NaCl and pH tolerance, enzymatic activity, resistance to antibiotics, antagonism against Vibrio sinaloensis VHPC23, and molecular identification.

The coronary stent quality is measured by many variables such as shape, material, design, manufacturing, and coating. From another prospective, it is evaluated by haemostasis and restenosis values. The aim of this paper is to reduce the effect of the coronary stent on the vascular system after the implantation process. This paper proposes using the polyimide P84 as a coating for coronary stents to reduce restenosis and haemostasis values. The experimental results have indicated that the elapsed time of the blood flow on a coated surface has been reduced to the half of a metallic one without coating. In addition to this, the surface tension has been decreased after coating and consequently the adhesion has been decreased by 26 times.

The distillation column is basically a MIMO process that means all the inputs and outputs are coupled to each other. It is very hard to control such type of process so, we have to eliminate the interaction among the inputs and outputs. Therefore the process can be converted to a single input and single output system (SISO). In order to convert the MIMO system to SISO system it is necessary to design a decoupler which will reduce the interaction between all the inputs and outputs.\n\nIn this paper, a generalized decoupling technique is proposed. The proposed technique uses relative gain array (RGA) to select proper pairing and hybrid approach involving Particle Swarm Optimization (PSO) and Bacterial Foraging Optimization Algorithm (BFOA) called Bacterial Swarm Optimization (BSO) technique to estimate the optimal elements’ values of steady state decoupling compensation matrix constituting the decoupling compensator unit. The proposed technique is applied on a two thermally coupled distillation column characterized with four Inputs-four outputs. This proposed technique proves wonderful success in minimizing the interaction between every input and all outputs except that output has been proper paired with.

In this paper, we consider a mixed integral equation in position and in time. Then, the solution of such integral equation is discussed and obtained in the space under certain conditions. The kernel of Fredholm is considered in position in the form of Carleman function, while the kernel of Volterra is taken in time as a continuous function. Using a numerical method we obtain a linear system of Fredholm integral equations in position. Then, using Toeplitz matrix method (TMM) and Product Nystrom method (PNM), the system of Fredholm integral equation, in each method, will be transformed to a linear algebraic system (LAS). Moreover, some examples are considered and the error estimate, in each case, is computed.

In this paper, we present approximate analytical solution of a time-fractional Biological Population equation via the fractional iteration method (FIM). The fractional derivatives are described in the Caputo sense. The approximate results show that the fractional iteration method is a very efficient technique to handle fractional partial differential equations. The fractional complex transform (FCT) with help of variational iteration method (VIM) is used to obtain numerical and analytical solutions for the fractional Biological equations. Fractional complex transform (FCT) is proposed to convert fractional Biological equations to its differential partner and then applied VIM to the new obtained equations. Several examples are given and the results are compared with (FCT) and exact solutions. The results reveal that the method is very effective and simple.
