(Noctuidae: Lepidoptera), a notorious and polyphagus pest of pulses and vegetables in India. Attempt has been made to initiate their mass multiplication for successful biocontrol programme. Behavioral studies, food stuffs, host selection aspects plays a crucial role in mass multiplication of biocontrol agents. Therefore, present work was conducted to study the optimum host age, specificity and host density for maximum progeny production of the parasitoid under laboratory conditions and later their release in the field for the management of pest species. The parasitoid caused highest mortality in the pest larvae of second instars, 4 day old larvae were attacked most with high percent parasitism, 39.00%. Optimum density for maximum progeny production of D. argenteopilosa was 20, which generate maximum parasitism (43.00%). Host specificity by exposing the parasitoids towards different host species and analyse parasitoid preference by S. litura > Helicoverpa armigera (Hubner) > Mythimna separata Walker > Achaea janata (Linnaeus). Nutritional requirement of parasitoid was tested with different foodstuffs and found 50% honey best suited for maximum longevity 8.2 and 11.4 days for males and females respectively. The longevity ratio also female biased, 1: 1.39 (Male: Female). From the results it concludes that D. argenteopilosa fed with 50% honey solution, exposed to 3-5 day old caterpillars of S. litura at density of 20 gave maximum progeny production and effectively utilized in the biocontrol programme.

An important class of such patterns involve subscripted subscripts, wherein an array value appears in the index expression of another array. Even though the information required to parallelize loops with such patterns is often available in the program, present compiler techniques fall short of analyzing that information. In this paper we present a study of subscripted subscripts, the properties that define the subscript arrays, and an algorithm based on symbolic range aggregation, that will help prove the presence of some of the properties of the subscript array in the program. We show that, in an important class of programs, the algorithm can boost the performance from essentially sequential execution to close to fully parallel.

In the class of irregular applications that we have analyzed, the presence of subscripted subscript patterns was one of the primary reasons why a significant number of loops could not be automatically parallelized. Loops with such patterns can be parallelized, if the subscript array or the expression in which the subscript array appears possess certain properties, such as monotonicity. The information required to prove the existence of these properties is often present in the application code itself. This suggests that their automatic detection may be feasible. In this paper, we present an algebra for representing and reasoning about subscript array properties, and we discuss a compile-time algorithm, based on symbolic range aggregation, that can prove monotonicity and parallelize key loops. We show that this algorithm can produce significant performance gains, not only in the parallelized loops, but also in the overall applications.

These procedures deal with multidimensional datasets that often require different feature engineering and data preparation techniques. Robust design methods proposed by Taguchi have been extensively used in engineering design problems in relation to quality improvement. However, the potential for robust design techniques in the domain of cybersecurity has remained unexplored. In this article, a network intrusion detection system has been developed by implementing the Mahalanobis-Taguchi System (MTS), which is a derivative of the Taguchi methods. In the context of intrusion detection, MTS provides a supervised learning approach in which the attack instances are distinguished from the normal instances based on the Mahalanobis Distance (MD). Since network logs contain a number of variables, a principal component analysis (PCA) based framework has been developed for feature reduction, and subsequently, MTS is applied for classification. This new method is named PC-MTS, the effectiveness of which is demonstrated through implementation on two network intrusion datasets, viz. NSL-KDD and IDS2017. The results show that the proposed method gives a high degree of accuracy at par with or even better than existing intrusion detection methods.

Considering air conditioning, evaporative cooler is used in dry climates. But such evaporative coolers are not suitable in humid environment and also their performance is poor in the places where ventilation is not proper. Reason behind this is nothing but, uncontrollable humidity increment in the working environment (cabin) due to process of evaporation. Report is sequential details about research carried out on the evaporative cooler in order to remove this disadvantage. The important parameter in whole report is nothing but relative humidity which should be maintained in specific range for getting better thermal comfort. Report briefly explains the basic concept required to understand evaporative cooling and performance of evaporative cooling.

The traditional VC technique is capable of sharing only a single secret. Many researchers have developed techniques for sharing multiple secrets. Most of these techniques use either a circular or cylindrical or ring shaped shares. These shares must be rotated by a specific angle to reveal the secrets. Theoretically, these techniques may give good results but practical implementation of these techniques is tedious. These techniques use ring or cylindrical shaped shares which are difficult to handle. The measurement of the angle by which the share has to be rotated is difficult. In this paper, we have proposed a (2, 2) VC technique capable of sharing two secrets using only two shares. The first secret can be revealed by overlapping both the shares, while for revealing the second secret, we have to flip the second share horizontally and then overlap on the first share. The other advantage of the proposed technique is that the two secret images can have different dimensions, such that the rows and columns of one secret image are less than or equal to the other secret image. The proposed technique is applied on different type of binary images and the quality of recovered secret images is evaluated using different performance metrics.

Every node has high mobility and fast-changing topology. Each node can sense its coverage area to make available services related to traffic control. To make a connection between nodes routing is done with the help of routing protocol. The reactive routing protocol called Ad-Hoc On-demand Distance Vector (AODV) is the most advanced and commonly used in topology-based routing. Nodes (i.e. Vehicles) are fast moving thus the connection between nodes breaks frequently. This paper, we are going to analyze the Quality of Service (QoS) parameters for UDP and TCP traffic types. This paper is presenting a normal AODV routing protocol to analyze QoS parameters that are Delay and Throughput.

It also try to coin the concept of utilization of Solar dryer at farm side. In a developing country like India, having the second largest population and agriculture as the source of income to nearly 60 % of the total population, post-harvest and storage loss is a major quandary, which needs to be addressed in due diligence. Many food preservation techniques like cold storage, drying, etc., have been evolved out over the years to tackle the above losses. The major constraint is that almost all the technologies are utilizing fossil fuel resources, which are depleting very fast and wise use of these precious resources are preferred for longterm energy sustainability. Therefore, sustainable methods for food preservation are the need of the hour. Solar drying is one of the best choices in this context. The effect of temperature to moisture contents against time and rate of dr...

In this technique the pixels of image are coded using adjusted binary coding and Golomb-Rice coding. The coding of the pixel depends upon the position of the pixel in the image. The original image template in the FELICS algorithm has four different cases for position of pixel, but in this modified image template for FELICS algorithm we have proposed five cases. The quality of compressed images is compared by using various image quality parameters. After using this modified image template, we get slightly better compression ratio and reduced bit rate, this is achieved without affecting the other image quality parameters.

In the class of irregular applications that we have analyzed, the presence of subscripted subscript patterns was one of the primary reasons why a significant number of loops could not be automatically parallelized. Loops with such patterns can be parallelized, if the subscript array or the expression in which the subscript array appears possess certain properties, such as monotonicity. The information required to prove the existence of these properties is often present in the application code itself. This suggests that their automatic detection may be feasible. In this paper, we present an algebra for representing and reasoning about subscript array properties, and we discuss a compile-time algorithm, based on symbolic range aggregation, that can prove monotonicity and parallelize key loops. We show that this algorithm can produce significant performance gains, not only in the parallelized loops, but also in the overall applications.

It also try to coin the concept of utilization of Solar dryer at farm side. In a developing country like India, having the second largest population and agriculture as the source of income to nearly 60 % of the total population, post-harvest and storage loss is a major quandary, which needs to be addressed in due diligence. Many food preservation techniques like cold storage, drying, etc., have been evolved out over the years to tackle the above losses. The major constraint is that almost all the technologies are utilizing fossil fuel resources, which are depleting very fast and wise use of these precious resources are preferred for longterm energy sustainability. Therefore, sustainable methods for food preservation are the need of the hour. Solar drying is one of the best choices in this context. The effect of temperature to moisture contents against time and rate of dr...

In this technique the pixels of image are coded using adjusted binary coding and Golomb-Rice coding. The coding of the pixel depends upon the position of the pixel in the image. The original image template in the FELICS algorithm has four different cases for position of pixel, but in this modified image template for FELICS algorithm we have proposed five cases. The quality of compressed images is compared by using various image quality parameters. After using this modified image template, we get slightly better compression ratio and reduced bit rate, this is achieved without affecting the other image quality parameters.
