Diabetic Macular Edema (DME) is a common retinal complication associated with diabetes. It is a major cause of permanent vision loss. Therefore early detection will be highly beneficial in controlling the progress of the disease. Since the ratio of people affected with the disease is very high when compared to the number of eye specialist, there is a need for automated diagnostic system for DME, so that only diseased persons can be referred to the specialist for further intervention and treatment. In order to assess DME, Detection of Hard Exudates is now considered as a standard method. In this paper the Hard Exudates are segmented using Fuzzy Clustering algorithm. Local Binary Pattern features are extracted from the segmented regions and are input to the Support Vector Machine (SVM) Classifer. The SVM classifier classifies the image as Normal and Abnormal.

Expansive soils possess undesirable engineering behaviour such as low bearing capacity, high shrinkage and swelling characteristics. It forms poor subgrade material due to low CBR values and hence excessive pavement thickness is required for designing flexible pavement. Ground improvement techniques such as soil stabilization are employed to improve the bearing capacity and to control volume change in expansive soils. The most commonly used method is addition of stabilizing agents such as lime or cement to the expansive soil. In developing countries like India, industrialization has led to the generation of large amount of fly ash,which poses a great challenge for its safe disposal without affecting the environment. In addition, the increasing cost of traditional stabilizing agents and the need for the economical utilization of industrial waste has paved way for an investigation into the stabilizing potential of fly ash in expansive soil. Hence, the present study focuses on the assessing the suitability of stabilized expansive soil with cement and fly ash for subgrade in flexible pavement. Cement was added to expansive soil at 0-4%. The percentage of fly ash, which is used in the present study, is varied from 0-8%. Test specimens were subjected to Atterberg limits,Differential free swell, Standard Proctor Compaction and CBR tests. This research helps to assess the behaviour of expansive soil mixed with cement and fly ash independently. Based upon the favourable results obtained, it can be concluded that the expansive soil can be successfully stabilized with cement or fly ash.

DC-DC converters are switched power converters. They are used to convert one DC voltage to another. Boost converters are inordinately used in industry as well as in research. The model of the converter system varies from ON state to OFF state. The major drawback is the unlimited supply of voltage and current. Hence a MPC is implemented to produce a constant voltage with varying input supply. The performance of MPC is further improved using NARMA-L2 control as shown in the simulation results in MATLAB.

The continuous scaling of VLSI technology and the possibility to run circuits in sub-threshold voltage range make it possible to implement standard cryptographic primitives within the very limited circuit and power budget of radio frequency identification (RFID) devices. However, such cryptographic implementations raise concerns regarding their vulnerability to both active and passive side-channel attacks. In particular, when focusing on RFID targeted designs, it is important to evaluate their resistance against low-cost physical attacks. A lowcost fault injection attack can be mounted, for example, by lowering the supply voltage of the chip with the goal of causing setup time violations. In this paper, we provide an in-depth characterization of a chip implementation of the AES cipher. Identifying sensitive logic signals allows us to suggest to the designer a tailored countermeasure strategy for thwarting these attacks, with a minimal impact on the circuit’s performance.

Automotive engineers are continuously researching new technology in the field of engine, transmission and suspension to improve fuel efficiency, power output and safety of automotive vehicles. Continuously Variable transmission (CVT) is one of the important steps towards it. CVT is an infinite gear system as it provides infinite gear ratio and it also helps in decreasing power loss. It helps in providing jerk free transmission, which can be observed in manual as well as in automatic gear transmission. There are different types of CVT available and one of the types is Pulley driven CVT. Primary aim of this project is to study various parameters like fly mass, drive pulley spring, driven pulley spring, cam angles and their effect on engagement rpm of CVT and also design manually operated model of CVT. As it is difficult to get the actual design specifications of CVT from the companies, some of the dimensions are assumed. The dimensions of other parts have been calculated based on the assumed dimensions. Experimentation is done on a Baja SAE vehicle which shows the effects of changing different parameters on engaging rpm of driven shaft. A static analysis as well as motion analysis is done on the CVT model.

A wireless sensor network (WSN) (sometimes called a wireless sensor and actor network [1](WSAN)[1]) are spatially distributed autonomous sensors to monitor physical or environmental conditions,[2] such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. The more modern networks are bi-directional, also enabling control of sensor activity. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance; today such networks are used in many industrial and consumer applications, such as industrial process monitoring and control, machine health monitoring,and so on. A large amount of different key distribution schemes were implemented, targeting different types of WSNs. These schemes face issues with respect to their requirements,implementations, and theoretic foundations [3]. Though security is regarded as a standalone component of the architectures of many systems, in case of wireless sensor networks, it must get adequate attention. In most application domains, the sensors are used to collect a specific type of data from particular target areas, and the collected data are often considered secret and are not intended for public disclosure. Hence, efficient and secure mechanisms are needed to transmit acquired data securely to the appropriate recipients.

Over the past decades, wireless sensor networks (WSNs) have been widely applied in many different fields in which routing protocol is one of the key technologies. Since a sensor node exploits a path depending only on the location information of neighbor nodes in geographic routing, routing protocol based on geographic information is more efficient. To solve the routing void problem in geographic routing, high control overhead and transmission delay are usually taken in wireless sensor networks. Inspired by the structure composed of edge nodes around which there is no routing void, this project proposed an efficient bypassing void routing protocol based on virtual coordinates. The basic idea of the protocol is to transform a random structure composed of void edges into a regular one by mapping edge nodes coordinates to a virtual circle. By utilizing the virtual circle, the greedy forwarding can be prevented from failing, so that there is no routing void in forwarding process from source to destination and control overhead can be reduced. Furthermore, the virtual circle is beneficial to reduce average length of routing paths and decrease transmission delay. The proposed protocol has higher delivery ratio, shorter path length, less control packet overhead, and energy consumption.

In this paper the thermal comfort condition for mushroom cultivation was studied. In addition to this the cooling load needed for bring that thermal comfort condition was calculated. Mushroom cultivation was done by so many peoples in the hot and dry climatic places. In the cold places the yield of mushroom was more compared with the cold climatic places this is due to thermal comfort condition needed for mushroom cultivation. The solution for even yield in dry and cold climatic condition is to bring the thermal comfort condition at dry places by means of a refrigeration system. To design a refrigeration system cooling load calculation is necessary. So a prototype model for refrigeration system geometry for mushroom cultivation was developed and its necessary cooling load was calculated.

A multiband broadcasting that can be used for mobile handsets is presented. This antenna consists of a smart micro strip patch antenna, passive antenna data broadcasting and a low noise amplifier. The design procedure of this antenna, in which the passive antenna shows very different impedances at each band, is also presented. It is proposed configuration can be used as a multiband receiving patch antenna for multiple band. In environments with locality of client demands, the use of multiple directional antennas at the Broadcasting has been shown to increase performance. In many cases such broadcasting systems fail to exploit the full potential of the multiple antennas as they do not take into account the geographical distribution of clients within the coverage area of the mobile. This letter proposes smart patch antenna based wireless push system where the beam width of each micro strip patch antenna is altered based on the current placement of clients within the network. Coupled with a modification of the broadcast schedule, the proposed approach significantly increases the performance.
