No full textPhaneroptera rentzi sp. nov. Fig. 1—a, i, j, o; Fig.2 —A–N, Diagnostic characters: Male ( ♂ ). Body yellowish green. Fastigium vertices scapus wider, apically narrow with obtuse, a fine median sulcus (Fig. 2C), strong pigmentation on the dorsal side of fastigium as well as the entire pronotum (Fig. 2B, D); anterior margin of pronotum flat, posteriorly concave; tegmen surpassing the hind wing, dorsally flat, clear wing venation, cerci of male strongly bent inward behind the sub genital plate (Fig. 2K), apex of cercus strongly acute with short and stout black spine (Fig. 2M and Fig. 1a), subgenital plate strongly bifurcate, incurved (Fig. 2 J and Fig. 1j). Colouration. Yellowish green colour. Female. Unknown. Type Material. Holotype: ♂, Dharmapuri (N 0 12007 ’11.21’’E 077051 ’.01.94’’), Tamilnadu, India. 11 II 2018. Coll. G. Divya and N. Senthilkumar. Deposited in Gass Forest Museum (GFM), Institute of Forest Genetics and Tree Breeding, Coimbatore, Tamilnadu (India). Distribution. Dharmapuri, Tamilnadu, India. Etymology. This species is named in honour of Dr D. C. F. Rentz, Australia. Discussion. The new species is completely differs from P. spinosa, P. myllocerca, P. falcata and P. gracilis on the structure of subgenital plate, supra anal plate, pronotum and fastigium vertices. P. rentzi, sp. nov. is entirely differ from the P. spinosa, P. myllocerca and P. falcata by the shape of cerci and subgenital plate. P. gracilis and P. rentzi, sp. nov. are look-alike however, the subgenital plate is entirely different (Fig. 1j, m). The lateral lobe of pronotum deeper than long, without white band; fairly and smoothly rounded not forming angle with disc, sharp emargination at posterior end of insertion. Subgenital plate bilobate at the apex. Distal lobe of subgenital plate not smoothly rounded but pointed. Apex of the cerci abruptly bent inwards. Stridulatory vein large almost as wide as left tegmen; distal end of file as in Fig. 2 E.Published as part of Divya, Govindaraj & Senthilkumar, Natchiappan, 2020, Contribution to the knowledge of the genus Phaneroptera (Tettigoniidae Phaneropterinae) with a new record from Tamilnadu, India, pp. 425-434 in Zootaxa 4860 (3) on page 426, DOI: 10.11646/zootaxa.4860.3.7, http://zenodo.org/record/441406

Defensing Confidentiality During Complete Packet Inspection On A Middlebox
No full textIn Internet to encrypt traffic, HTTPS provides secure and private data communication between clients and servers. Network operators often deploy middleboxes to perform deep packet inspection DPI to detect attacks using techniques ranging from simple keyword matching to more advanced machine learning and data mining analysis. But this approach cannot protect users' private information from a service provider who deploys middleboxes. SPABox, a middlebox based system that supports both keyword based and data analysis based DPI functions over encrypted traffic. SPABox preserves privacy by using a novel protocol with a limited connection setup overhead. In this paper to further improve the performance, we are working on the network performance requirements.

Statistical static timing analysis considering process variations and crosstalk
No full textIncreasing relative semiconductor process variations are making the prediction of
realistic worst-case integrated circuit delay or sign-off yield more difficult. As process
geometries shrink, intra-die variations have become dominant and it is imperative to
model them to obtain accurate timing analysis results. In addition, intra-die process
variations are spatially correlated due to pattern dependencies in the manufacturing
process. Any statistical static timing analysis (SSTA) tool is incomplete without a model
for signal crosstalk, as critical path delays can increase or decrease depending on the
switching of capacitively coupled nets. The coupled signal timing in turn depends on the
process variations. This work describes an SSTA tool that models signal crosstalk and
spatial correlation in intra-die process variations, along with gradients and inter-die
variations

Groundwater management in alluvial, coastal and hilly areas
No full textGroundwater plays a major role in the modern world being used for drinking, irrigation and industrial development. The increasing population and developments in agricultural and industrial sectors depends on groundwater as it is a reliable source, and so it leads to overexploitation of groundwater without due regard to the recharging capacity of the aquifers. Groundwater extraction from most of the aquifers around the world has exceeded its recharge capacity, and hence the water table has gone down drastically leading to adverse environmental consequences like land subsidence and water quality deterioration. A proper assessment of groundwater resource should be undertaken to ensure sustainable management of groundwater. Hence, the present study proposes empirical methods for the sustainable groundwater resource management in alluvial, coastal and hilly regions
