COLOR HISTOGRAM BASED MEDICAL IMAGE RETRIEVAL SYSTEM

This paper aims to focus on the feature extraction, selection and database creation of brain images for image retrieval which will aid for computer assisted diagnosis. The impact of content-based access to medical images is frequently reported but existing systems are designed for only a particular context of diagnosis. But, our concept of image retrieval in medical applications aims at a general structure for semantic content analysis that is suitable for numerous applications in case-based reasoning. By using the features, the database created for comparison. The color histogram is used to measure the similarity between the stored database image and the query image. The image which is more similar to the query image is retrieved as the resultant image. If the quer

MODIFICATION TO SPIHT ALGORITHM USING INCREMENTAL THRESHOLD FOR IMAGE COMPRESSION

The Modified SPIHT represents a more efficient implementation of the SPIHT algorithm by using variable thresholds to sort the list of insignificant pixels (LIP) and the list of insignificant sets (LIS). We observe two interesting facts: (I) most of the initial subsets in LIS are not only insignificant with respect to the maximum threshold, but also insignificant with respect to the smaller threshold. And (2) Most of the pixels generating from sorting LIS are smaller than the current threshold. Based on these two observations, it represents a new image codec method, which can make the binary encoded outputs more efficient, and can work well on different image sizes and different decomposition levels

Learning to Estimate Multi-Relation Aggregation Functions

Multi-relation aggregation queries process the join operator before computing the aggregation function. This join is arguably the most costly operation since traditional join algorithms spend majority of their time trying to join the parts of the relations that do not generate any output tuples. This causes slow response times with large datasets in interactive exploratory environments. In this paper, we outline our vision on using online learning and adaptation to execute binary joins efficiently and to use the samples obtained from our join algorithm to estimate the aggregation functions. In our approach, the scan operators learn which parts of the relations are more likely to join during the query execution and estimate the average with confidence intervals as the joins are produced. Our empirical studies indicate that this approach outperforms current join algorithms and gives faster aggregate estimates

A Review Paper on Automated Fuel Pump Security System

The paper proposes an automated system for fuel pumps which aims at safe and secure fuel delivery, ensuring that the customer gets the equivalent amount of fuel for what he or she has paid, hence successfully eliminating any sorts of fraud or malpractices that mightoccur at a fuel pump station. The existing system involves resetting the transaction when the nozzle has been placed back on the dispenser, which, subsequently leads to misconducts as the operator may or may not reset the same and fuel the vehicle with inappropriate or lesser amount of fuel. The proposed system makes use of a RaspberryPi for resetting the fuel vending machine. It will automatically reset the dispenserwhen the vehicle passes the unit, this will prevent the possibility of fuel theft. The system will also use Bluetooth smart for communication between the RaspberryPi and the reset logic.A RaspberryPi camera will monitor the fueling area which will be displayed to the customer on a screen

Physiological status of male and female Popillia japonica (Coleoptera: Scarabaeidae) affects mating and grouping behavior

Because mating may be costly, sexually active males or females are predicted to be in relatively good physiological condition and may preferentially direct their mating behavior toward relatively high-quality mates. We tested this hypothesis in Japanese beetles (Popillia japonica Newman), a pest species in which males and females may be either isolated or in aggregations while feeding on host plants. We examined male size and lipid content and female size and egg load with respect to both their pairing status and whether they were isolated or in aggregations. Males that were paired had the highest lipid levels, and single, isolated males had the lowest. Paired females had the highest egg loads and single, isolated females had the lowest. Neither male nor female size was related to pairing status. Females captured during the times of relatively high pairing frequency (i.e., morning and evening) had higher egg loads than females captured at times of lower pairing frequency (i.e., afternoon). These results suggest that mating and aggregative behaviors in Japanese beetles are dependent on the physiological status of males and the reproductive condition of females

Wireless Sensor Network using DRINA

On demand routing protocols give climbable and price effective solutions for transferring packets in mobile spontaneous networks (MANET). A wireless detector network could be a assortment of distributed nodes to watch and additionally to transmit their information from detector network to a sink node. In wireless detector network, detector nodes area unit set close to every different and additionally act with one another through information routing. In wireless detector network, the information routing takes place in non-aggregated manner would force a lot of energy. Energy conservation is that the major issue in wireless detector network. During this work we have a tendency to propose jury-rigged information routing with in-network aggregation formula which may address this energy consumption issue. It uses information aggregation technique and it will be effective in routing. so information aggregation is beneficial for increasing information accuracy, elimination of information redundancy, and reduction of communication load alongside reducing energy consumption

In vitro florigenesis: an efficient regeneration system avoiding time consuming vegetative phase in popular Indian soybean variety JS-335

458-466Soybean (Glycine max L.) is a major legume crop cultivated principally as protein rich bean. Improving quality and yield received considerable attention from researchers. Here, we explored molecular approaches to improve soybean quality and yield. In spite of recalcitrance, soybean plants successfully regenerated through complex and time consuming in vitro regeneration protocols via organogenesis and/or somatic embryogenesis and being used for transgenic development. Transformation efficiency is highly dependent on the regeneration as not all the cells transformed lead to the recovery of viable plant regeneration. Consequently, efficient in vitro regeneration found to be directly associated with the recovery of transformants. In the present study, we standardized the in vitro florigenesis using cotyledonary node with axillary bud as explant of soybean variety JS-335. Flower buds were directly induced from proximal end of the explant on Murashige-Skoog (MS) medium augmented with thidiazuron (TDZ) and α naphthalene acetic acid (NAA). TDZ proved a potential growth regulator to induce in vitro florigenesis. As a result of in vitro fertilization, pods were developed from flowers and matured within 40-45 days on hormone-free medium. Pods and seed set under in vitro conditions resemble pods and seeds produced under in vivo conditions. This pathway of in vitro florigenesis showed great potential for successful induction of in vitro flowering, which in turn can be explored in producing transgenic soybean seeds in popular Indian soybean genotype without escaping transgene

Green synthesis and anxiolytic activity of some new dibenz-[1,4] diazepine-1-one analogues

AbstractA facile, green approach for the synthesis of some new dibenz[1,4]-diazepine-1-one by a three component reaction of Diamine, 1,3 diketone and aromatic aldehyde using oxalic acid as catalyst in water is described. The products are formed in good yields (92–94%). Newly synthesized dibenz [1,4]-diazepine-1-one analogues were evaluated for the anxiolytic activity by the elevated plus maze method. From the activity data it is observed that compounds, 4g, 4h and 4k show promising anxiolytic activity

Genetic divergence of Chikungunya viruses in India (1963-2006) with special reference to the 2005-2006 explosive epidemic

Re-emergence of Chikungunya (CHIK), caused by CHIK virus, was recorded in India during 2005-2006 after a gap of 32 years, causing 1.3 million cases in 13 states. Several islands of the Indian Ocean reported similar outbreaks in the same period. These outbreaks were attributed to the African genotype of CHIK virus. To examine relatedness of the Indian isolates (IND-06) with Reunion Island isolates (RU), full-genome sequences of five CHIK virus isolates representative of different Indian states were determined. In addition, an isolate obtained from mosquitoes in the year 2000 (Yawat-2000), identified as being of the African genotype, and two older strains isolated in 1963 and 1973 (of the Asian genotype), were sequenced. The IND-06 isolates shared 99.9 % nucleotide identity with RU isolates, confirming involvement of the same strain in these outbreaks. The IND-06 isolates shared 98.2 % identity with the Yawat-2000 isolate. Of two crucial substitutions reported for RU isolates in the E1 region, M269V was noted in the Yawat-2000 and IND-06 isolates, whereas D284E was seen only in the IND-06 isolates. The A226V shift observed with the progression of the epidemic in Reunion Island, probably associated with adaptation to the mosquito vector, was absent in all of the Indian isolates. Three unique substitutions were noted in the IND-06 isolates: two (T128K and T376M) in the Nsp1 region and one (P23S) in the capsid protein. The two Asian strains showed 99.4 % nucleotide identity to each other, indicating relative stability of the virus. No evidence of recombination of the Asian and African genotypes, or of positive selection was observed. The results may help in understanding the association, if any, of the unique mutations with the explosive nature of the CHIK outbreak
