Figure 12 in Conversion of the egg nest to a brood nest by the female Brettus cingulatus (Araneae: Salticidae: Spartaeini)
No full textFigure 12. Immature Brettus cingulatus feeding on late instar I (fully pigmented) B. cingulatus spiderlings in an untended nest. It appears that the female left this brood without converting the egg nest to a brood nest, and the instar I spiderlings, now exposed and vulnerable outside of that nest, had no guardian. At this stage (instar I) it is likely that the spiderlings were still completely blind. Photographs by Hemanth Kumar H M.Published as part of Hill, David E., C., Abhijith A.

Some New Extensions of Multivalued Contractions in a b-metric Space and Its Applications
No full textThe Hβ-Hausdorff–Pompeiu b-metric for β∈[0,1] is introduced as a new variant of the Hausdorff–Pompeiu b-metric H. Various types of multi-valued Hβ-contractions are introduced and fixed point theorems are proved for such contractions in a b-metric space. The multi-valued Nadler contraction, Czervik contraction, q-quasi contraction, Hardy Rogers contraction, weak quasi contraction and Ciric contraction existing in literature are all one or the other type of multi-valued Hβ-contraction but the converse is not necessarily true. Proper examples are given in support of our claim. As applications of our results, we have proved the existence of a unique multi-valued fractal of an iterated multifunction system defined on a b-metric space and an existence theorem of Filippov type for an integral inclusion problem by introducing a generalized norm on the space of selections of the multifunction

Improving Intent Classication By Automatic Data Augmentation Using Word Sense Disambiguation
No full textabstract: Virtual digital assistants are automated software systems which assist humans by understanding natural languages such as English, either in voice or textual form. In recent times, a lot of digital applications have shifted towards providing a user experience using natural language interface. The change is brought up by the degree of ease with which the virtual digital assistants such as Google Assistant and Amazon Alexa can be integrated into your application. These assistants make use of a Natural Language Understanding (NLU) system which acts as an interface to translate unstructured natural language data into a structured form. Such an NLU system uses an intent finding algorithm which gives a high-level idea or meaning of a user query, termed as intent classification. The intent classification step identifies the action(s) that a user wants the assistant to perform. The intent classification step is followed by an entity recognition step in which the entities in the utterance are identified on which the intended action is performed. This step can be viewed as a sequence labeling task which maps an input word sequence into a corresponding sequence of slot labels. This step is also termed as slot filling.
In this thesis, we improve the intent classification and slot filling in the virtual voice agents by automatic data augmentation. Spoken Language Understanding systems face the issue of data sparsity. The reason behind this is that it is hard for a human-created training sample to represent all the patterns in the language. Due to the lack of relevant data, deep learning methods are unable to generalize the Spoken Language Understanding model. This thesis expounds a way to overcome the issue of data sparsity in deep learning approaches on Spoken Language Understanding tasks. Here we have described the limitations in the current intent classifiers and how the proposed algorithm uses existing knowledge bases to overcome those limitations. The method helps in creating a more robust intent classifier and slot filling system.Dissertation/ThesisMasters Thesis Computer Science 201
MICRO-MORPHOLOGICAL AND BIOCHEMICAL RESPONSE OF MUNTINGIA CALABURA L. AND IXORA COCCINIA L. TO AIR POLLUTION
No full textThe present study was carried out to assess the air pollution effects on micro morphological and biochemical parameters of Muntingia calabura and Ixora coccinia. In polluted area samples the number of stomata and unclogged stomata were found to be less then control, where as the number of clogged stomata are found to be higher in the polluted site when compared to control. The stomatal pore length and breadth were also found to be less in polluted area in both the plants when compared to control. The number of epidermal cells, trichome length values was found to be less then control in both the plants. While the trichome number was found to be less than control in Muntingia calabura and more then control in Ixora coccinia. The stomatal index in both the species is higher than the control. The amount of chl. a, chl. b, total chlorophyll content were found to be higher in control samples when compare to polluted samples. But relative water content, ascorbic acid, pH and air pollution tolerance index were found to be higher in polluted site samples when compare to control samples

No full textAn Authenticated Bit Shifting and Stuffing (BSS) Methodology for Data Security
No full textProviding security to the data means the third party cannot interpret the actual information. When providing authentication to the data then only authorized persons can interpret the data. One of the methodology to provide security is cryptography. But in previous paper we have proposed a methodology for the cryptography process is BSS. In Bit Shifting and Stuffing (BSS) system to represent a printable character it needs only seven bits as per its ASCII value. In computer system to represent a printable character it requires one byte, i.e. 8 bits. So a printable character occupies 7 bits and the last bit value is 0 which is not useful for the character. In BSS method we are stuffing a new bit in the place of unused bit which is shifting from another printable character. To provide authentication a four bit dynamic key is generated for every four characters of the encrypted data and the key is also maintained in the data itself. While decryption the key is retrieved from the data and check whether the data is corrupted or not
