Abstract: This paper introduced a supervised method for blood vessel detection in digital color retinal images. Neural network (NN) scheme is used for pixel classification and computes a 7-D vector composed of gray-level and moment invariants-based features for pixel representation. DRIVE databases are used for this purpose. Segmentation of blood vessels in retinal images allows early diagnosis of diseases. The results are encouraging and will be used for further application such as personal identification and are evaluated in terms of sensitivity and specificity and accuracy.

Keywords: Diabetic retinopathy, moment invariants, retinal blood vessel segmentation, gray level features.

Abstract: The organization, depending on its unique characteristics, needs to establish a system of how the records will be restored that will manage the stored records and which will maintain a list of the stored records.  The regulation that governs retention periods depends on the organization. Effective records management is more than just a filing and storage system. Records management is the systematic control of recorded information that is required in the operation of an organization.

Abstract: This review paper summarizes the current knowledge about high internal phase emulsion polymerization (PolyHIPEs), route of polymerization, where an emulsion is formed. The polymerization of the external phase occurs around emulsion droplets of the internal phase, thus creating an open, highly interconnected porous network, after the removal of the internal phase. This review further describes the characteristic features of these monolithic materials, and their application in several areas in material science, such as solid supported organic chemistry, sensoring, cell culturing and tissue engineering. The paper additionally describes how each of these characteristics can be tailored in order to meet the requirements for the desired applications.

Abstract: Classifier is a type and can own generalizations, thereby making it feasible to define generalization relationships to other classifiers. In this classifier is a redefinable element, as it is feasible to redefine nested classifiers. In the classification given a set of data representing examples of a target concept make a model to explain the concept and this model classifying future or unknown cases. Classification also estimates the accuracy of the model. This paper presents a survey of current methods for classification designs and the various existing issues. Many tasks that have been conventionally done by humans are now being passed to machines; one may therefore expect there are now an abundance of vision problems posed to computers. In this classifier system is much more than a simple expert system that can learn from experience (which in itself is an immense boon). In this paper design classifier for more than one class and for designing classifier used different operation of genetic programming. The results show that by applying different crossover together with different Mutation increase the performance of the classifier.

Abstract: This study shows that how the performance of a natural draft cooling tower can be improved by optimizing the heat transfer along the cooling tower packing using a suitable water distribution across the plane area of the cooling tower. In natural draft cooling towers, a process of counter flow heat transfer, which the water is cooled by air, takes place. Between the water and the air, a boundary layer is established, which is considered to be saturated air at the same temperature as the water. In the heat transfer process more than two-thirds of the heat is transferred by evaporation, with the rest being transferred by convection. An improved cooling tower performance is the result of an optimum mass flow rate of cooling water with respect to the power plants operating conditions. It is also possible to improve conditions with a proper distribution of water across the cooling towers plane area. On the basis of cooling air measurements, it is possible to distribute the water in such a way it ensures the homogeneity of the heat transfer and a reduction of entropy generation, thus minimizing the amount of energy lost. The velocity and temperature fields of the airflow were measured at an arbitrary point above the spray zone over the entire plane area of the cooling tower. The structures of the moist air velocity profiles and the temperature profiles above the spray zone were used as input data for optimum water distribution. Optimum water distribution system is applied with minimum possible alterations in existing system to ensure the minimum expenditure. Further, the experiment is carried out to evaluate the cooling tower performance with optimal water distribution system.
