Convolutional Neural Network is one of state-of-the-arts and demonstrated its superior performance in various computer visions systems recently. The conventional convolutional neural network has one-way structure to train image information with fixed sizes of filters in general. However, this structure only learns image information followed by one fixed sizes of filters and this is not the best to achieve high performance of the network. In order to achieve high performance of the network, this paper suggests a novel convolutional neural network which consists of spatial transformer network and multi-structure convolutional neural network. Spatial transformer network is robust against distorted images. Multi-structure convolutional neural network uses different sizes of filters for global and local information from the given images. The proposed algorithm, spatial transformer with multi-structure convolutional neural network (SPMCNN) demonstrates its classification performance on German traffic sign recognition benchmark.

The concept of passivity for nonlinear systems attracted new interest in nonlinear system control. This work aims to develop a control algorithm using Passivity Based Control (PBC) for a Two Input Two Output (TITO) system namely spherical-conical interacting coupled tank system in real time. Conical tank spherical tank combination together with the interaction makes the system highly nonlinear system. Real time model of the SISO and TITO systems are obtained experimentally by black box modeling. A computer based control system is developed and the process data is obtained using USB based VUDAS-100 data acquisition module. The algorithm for control is developed in the PC with conventional PI controller and also with PBC and the controller performance is compared. The robustness of the controllers is validated by imposing both servo and regulatory operations. Both the SISO and TITO system results obtained in real time shows that PBC works efficiently with improved performance compared to ZN based PI controller.

The compressive strength of lightweight concrete using palm kernel shell (pks) and periwinkle shell (pws) is reported. The strength as a function of aggregates ,age, and density were investigated. The strengths were measured at interval of 7-day for 28 days. The strengths obtained were in the range of those reported in the standards for lightweight concretes. The densities were also observed to increase with age and fall within the range of those reported in the literature. The results for the compressive strength showed that the strength increases with age for both aggregates.

India is an Agricultural Nation. Its primary occupation is Agriculture. Today, India ranks second worldwide in farm output. Agriculture and allied sectors like forestry and fisheries accounted for 13.75% of the GDP in 2013, about 50% of the workforce. The crops are generally grown in combination and a particular crop occupies a position of total isolation from other crops. The studies of crop combination regions constitute an important aspect of agricultural geography as it provides a good basis for agricultural regeneration. Through different regions may have different climate and soil conditions. But each region is Individual to crops. For a comprehensive and better understanding of agricultural system the study of crop combination is of great significances and is essential for agricultural planning. The present study enlights to the crop combinations in Thiruvarur District. Agricultural Geography is very need for rural planning, because high density of population and increasing annual growth rate of population. It is necessary to producer cultivate more crops in the same field. So diversification and suitable combination of crops with short duration is necessary for an increase in the production. The study of crop combination is also helpful for the study of the comprehensive area development planning particularly for the rural areas.

Human Bones are very important elements of human body. A bone is a rigid and brittle organ that constitutes part of the vertebral skeleton. The skeletal system is subjected to a complex System of loading exerted by the forces of gravity and the muscles attached to the bones. Such loading modes include tensile, compressive, bending, and torsional forces applied to the bones of the skeletal system. The proposed work is aimed to investigate correlation between HU, STRENGTH & BMD of humerus bone and evolution of humerus by torsion testing setup. Model of human humerus bone sample obtained from CT- scan in the form of Hounsfield Units (HU) scale and BMD obtained from Dual-Energy X-ray Absorptiometry (DEXA) scan.
