A field experiment was conducted to study the genetic variability, heritability and genetic advance of seven characters namely, days of first flower, plant height, number of nodes per plant, number of fruits per plant, fruit length, single fruit weight and fruit yield per plant in the segregating generations of crosses Arka Anamika x MDU 1 and Parbhani Kranti x MDU 1. For fruit yield per plant in all the crosses, the variability in F2 generation in general were high when compared to F3 generation. High PCV and GCV were observed in all three crosses for number of nodes per plant, number of fruits per plant and single fruit weight. The traits single fruit weight and fruit yield per plant showed high heritability along with high genetic advance in all the crosses which indicated that is might be due to the predominance of additive gene effects.Keywords

Currently, polymer lattice composites reinforced with filaments, for the substances which holds expansion in livelihoods due to of their optimal mechanical qualities. Despite these slants, the regardless of what you look like at it utilization of made fiber-animated polymer composite tends to reduction as a result of their high-beginning expenses, their utilization in non-helpful basic structures or all the more all their antagonistic typical effect. Of course, the grow excitement for using basic strands as backing as a piece of plastics to substitute standard built fibers in some assistant applications has transform into one of the essential concerns to inspect the capacity of using trademark strands as fortress for polymers. In the light of this, researchers have focused their thought on general fiber composite (i.e. bio-composites) which are made out of brand or mechanical pitches, propped with run of the mill fiber. The utilization of characteristic strands, got from easily available resources, as spiraling fibers in both thermoplastic and thermo set structure filaments outfit with acceptable natural focal points concerning amazing pointlessness and rough material utilization.Keywords

Combining ability analysis was studied in a line x tester analysis of rice (Oryza sativa L.). The analysis of variance for combining ability revealed that the variance due to GCA and SCA were highly significant for all the characters indicated that nonadditive gene actions were involved in the expression of the traits. Among the line AURC 14 and testers IR 64 and ADT 43 were considered as the best general combiners, while hybrids AURC 1×ADT 36, AURC 8×ADT 36, AURC 8 ADT 43, AURC 10×ADT 43, AURC 14×ADT 36, AURC 14×TRY 1, AURC 22×IR 64, AURC 22×TRY 1 and AURC 25×ADT 36 as good specific combiners for grain yield and other yield contributing and quality traits. The promising line AURC 14 and testers IR 64 and ADT 43 which are having high GCA effects in desirable direction for yield components and for quality traits may be incorporated in crossing programme. The crosses AURC 14×TRY 1 and AURC 22×IR 64 exhibited good SCA effects for major yield and more than seven yield contributing characters. This may be exploited for better yield and quality either by exploiting them through heterosis breeding or involving them in multiple cross breeding programme.Keywords

A Fault-tolerant dynamic scheduler meant for grid applications that uses job replication along with combines the compensation of static scheduling, specifically no overhead for the mistake free case, and low overhead in case of a fault. The dependency arrangement of a parallel program can be described by means of a directed acyclic graph (DAG). Scheduling graph consists of ordering the jobs and mapping them to processing units. Faults can happen at any point during time. A fault can be detected either because a processing unit and it does not send data at a prearranged time. Provide that fault-tolerance can be achieved while detecting that a processing unit has stopped through completing of a job, the status of this job is recovered from some checkpoint, and this job is re-executed on another processing unit, and all jobs (potentially) to be executed on this processing unit are reorganize to one more processor. Co-allocation involves transmission jobs to favorable resources. This is achieved by obtaining information from a variety of nodes of the grid and updating them as and when a modification occurs and assigning resources to the jobs based on their specifications and performances.Keywords

The present investigation was carried out in the Department of Horticulture, Faculty of Agriculture, Annamalai University, during the period 2014 - 2015 to asses the correlation and path co-efficient analysis of 60 genotypes of brinjal for yield and shoot and fruit borer tolerance. The experiment was laid out in Randomized Block Design with three replications. Among the sixteen morphological characters studied, number of long styled flowers per plant (8.803), number of short styled flowers per plant (5.403), number of fruits per plant (3.099), fruit weight (0.757), days to first harvesting (0.133) and shoot and fruit borer incidence (0.082) showed positive direct effect in path co-efficient analysis. Positive correlation was recorded for fruit weight (0.885), fruit girth (0.644) and number of fruits per plant (0.622). Therefore, these characters are important which may be included in selection criteria for improvement in fruit yield per plant as well as tolerance to shoot and fruit borer incidence.Keywords

Objectives: To study the yield behavior and plastic flow of an anisotropic sheet metal during forming operations, various mathematical formulations of the plastic state of the sheet metals have been proposed, known as yield functions. Different yield functions pertain to different criteria and have different characteristics. Methods/Statistical Analysis: There are several yield criteria proposed for the study of yield behaviors of sheet metals. This paper aims at reviewing the most frequently and commonly employed for the purpose yield criteria i.e. Hill 1948, Barlat 1989, Hill 1990 and BBC 2000. The study is focused on discussing the form of each criterion, their implementation details and comparing their predictive accuracies. Findings: The methods followed to obtain the yield surface diagram have been reviewed and discussed. Application/Improvement: Inference has been drawn based upon the agreement between theoretical and experimental value for a particular case.Keywords

Primary and secondary school education plays important role in the knowledge development of any country. In India, government schools gaining less admission due to the infrastructure and quality of education. There are many proactive methods taken by the government to ensure that the school education empowers the students in the knowledge acquisition. Performance assessment of the schools, teachers and students is required at the periodic interval to validate the quality of the education. Also, school education department requires multi-dimensional reports of the school, staff and students for the allocation of funds and implementation of different schemes. Currently, these reports are prepared manually in paper format and communicated to the district offices. It is time consuming as well as requires man effort. This paper proposes an android based performance assessment system by which the details can be collected through android mobiles/tablets and stores in the server. Web based system is also facilitated to the schools to input the details whenever required. It helps the school education department to extract the data at anytime, anywhere. Also, this system reduces the time and effort of the staff in manual preparation. The results are evaluated for the effectiveness and found that android based mobile application gives good results.

The present study was intended to screen the wild shrimps of Andaman and Nicobar Islands (ANI) against infectious diseases. A total of 175 shrimp samples (35 pools) consisting of Fenneropenaeus indicus, Penaeus monodon, Penaeus merguiensis and Metapenaeus monoceros were collected from different landing centres across ANI. Out of 35 pools of samples analysed by polymerase chain reaction (PCR), a total of 10 pools of Penaeus monodon collected from Betapur (1 pool), Lohabarrack (4 pools) and Campbell Bay (5 pools) were found positive for Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV). Nucleotide sequence of IHHNV isolated from ANI showed 100% identity to the sequences of IHHNV reported from Vietnam, Taiwan, Australia, China, Egypt, USA, Ecuador, 99% identity to IHHNV reported from Brazil, Venezuela, Korea, 96% identity to IHHNV reported from Thailand and 95% identity to IHHNV reported from India. Based on phylogenetic tree analysis, IHHNV of ANI is closely related to IHHNV of Vietnam. Histopathological analysis revealed typical eosinophilic intranuclear cowdry type A inclusion bodies in gill lamellae which further confirmed the IHHNV infection. The present study provides a definitive evidence for the first report of infectious IHHNV in wild P. monodon from ANI.Keywords

Rice is one of the main staple food of man and is grown in almost all the tropical and subtropical regions of the world. An experiment was carried out to investigate the effect of pre-sowing seed hardening treatment with different chemicals such as 1% CaCl2, 1% KCl, 1% KNO3 and 1% NaCl and organics such as 10% cow dung and 3% panchagavya on seed quality and seed yield in rice cv. ADT 36. In general seed hardening treatment of rice before sowing significantly increased the seed quality characteristics and yield attributing characters when compared to untreated seeds. From the result, it was observed that 1% CaCl2 seed hardening treatment improved the seed quality characters such as germination percentage, speed of germination, shoot length, ischolar_main length, seedling length, dry matter production, vigour index and yield attributing characters such as number of productive tillers per plant, number of seeds per panicle and seed yield per plant.

This paper details the failure analysis of deformed passenger car door lock case and presents a solution to avoid the part deformation during caulking process. This failure was observed during the assembly of case and its cover by caulking process. Mechanical properties and chemical composition of case (Zn Al4 material) has been checked by universal testing machine and spectra material analyser. The material composition having less aluminium content leads to the casting strength and cast ability losses. In order to get the exact load requirement for caulking process, analysis has been carried out by using finite element method. In finite element method, the case and case cover model has created by AUTODESK INVENTOR and stress analysis was carried using same software. The induced stress and deflection are obtained for various load conditions. The experimental measurement was taken from the machine by using load cells. By comparing the experimental data with FEM data we found that the problem happened due to the overload. From this result data the machine design was optimized by changing booster and cylinder which is used to generate the load. The hydro pneumatic circuit of the caulking machine has been optimized and redesigned to avoid future problems.Keywords

Heat treatment of metal alloys is one of the most widely used techniques for achieving the desired mechanical properties by modifying the microstructure namely the grain and or by altering the second phases present in heat treat able alloys. At times heat treated materials undergo further process like forming, machining, welding etc. Thus the present work describes the effect of heat treatment of AISI 1050 steel and its associated micro structural changes that correlate it with the mechanical behaviour. AISI 1050 steel is widely used in the production of bearings, landing gear, actuators and aerospace structural components. In this study, different samples of AISI 1050 steel were heat treated to temperature above the austenitic region and were subjected to annealing or normalising, or spheroiding. It is indicative that the properties of the AISI 1050 steel can be easily altered by heat treatment to suit a particular application and for secondary processing. The property comparison includes micro structural grain size, yield strength, tensile strength, hardness and percentage elongation. Thus the results provide a better insight on the process of increasing the versatility of the AISI 1050 steel for its demanding use in aerospace structural applications and related mechanical processing. It was found that the effect of heat treatment has resulted in increased grain size, decreased strength and hardness, and improved properties which were more suitable for machining and forming process.Keywords

Automotive side impacts are particularly dangerous as location of impact is very close to the passenger, who can be immediately reached by the impacting vehicle. FMVSS 214 static is a US safety regulation for occupant safety during side impacts, in which the vehicle is tested at static loading conditions to measure its load baring capacity and integrity of side closures. The CAE load case, virtually simulating the test, was handled as a quasi-static problem in this study. Impact beam is a component that helps in improving vehicle passive safety performance during side impacts by minimizing door intrusion to the occupant cabin. It plays an important role in achieving side impact regulatory norms. Through this study, a mass optimized front door impact beam design was developed for a passenger car with the help of CAE simulations; FMVSS 214S regulation norms are met. Component thickness, material and cross section shape were the design variables considered for the study. A methodology to perform the component level simulation of the impact beam loading such that it replicates component behaviour during full vehicle simulation was developed. This has helped in reducing the total problem calculation time in solver. This also has minimized the computational cost for the project. CAE simulations required for the study were done using LS-DYNA. ANSA and PRIMER were used as pre-processors and hyper-graph and meta-post were used for post processing.Keywords

This study presents the optimization of machining parameters on ZE41 Mg alloy fabricated by gravity die casting and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Focus on the optimization of machining parameters using the technique to get minimum surface roughness, cutting force, thermal stress, residual stress, chip thickness and maximum MRR. A number of machining experiments were conducted based on the L27 orthogonal array on computer numerical control vertical machining center. The experiments were performed on ZE41 using cutting tool of an ISO 460. 1-1140-034A0-XM GC3 of 20, 25 and 30mm diameter with cutting point 140 degrees, for different cutting conditions. TOPSIS and ANOVA were used to work out the fore most important parameters cutting speed, feed rate, depth of cut and tool diameter which affect the response. The expected values and measured values are fairly close. Finally, the study for optimizing machining process is surveyed and results show improvement in real experiments.Keywords

Industrial enterprises increasingly demand optimum quality of products keeping in consideration a strict adherence where forming parameters are concerned. As far as incorporating the vital forming process upon an assortment of materials is concerned, it has grown excruciatingly challenging for industrial enterprises for laying out the adequately precise and suitable parameters. The flaws that are engendered during the process of sheet metal forming are inevitable. Flaws of this nature can be, however, kept within minimal proportions by introducing variations into the process parameters by Trial and Error methodology. This evidently results in a subsequent financial loss, not to mention an irrevocable loss of time and material. Dynaform simulation of defects combined with optimization is carried out with the help of Minitab. This method, as can be conjectured with considerable ease, yields optimum results, for it replaces much to our convenience the need for specialist industrial expertise besides leading to considerable savings in cost, time and material. This study would optimize the SS304sheet metal forming parameters FLD, thickness and thinning with three input parameters, namely, the lower binder force, tool travel velocity and binder close velocity.Keywords

The emergence of social media on the face of global society has created a new network of social connections. With the advancement in the technology, the interest of Millennials has shifted from traditional methods to the social media for gaining information. Millennials constitutes a large proportion of world‘s population with immense purchasing power enabling many businesses targeting them. Researches show that this generation has different buying behavior as compared to the earlier generation characterizing them as one of the biggest consumer community in the overall global consumption. The role social media played in making them one of the biggest consumer community has also revolutionized the market for Electronic Products. Social networking has armed the fashion apparel industry with the ability to grasp a gigantic mass of consumer with just a single update on social media. Almost all the electronic product brands and consumers are now interacting genuinely on social media platform. This area, studying the impact of social media on consumer buying behaviour has become a favorite topic among the researchers across the world. The current paper aims to dig deeper into the impact of social media on buying behaviour of Millennials at the same time finding the factors influencing the buying of Electronic Products on social media platform.Keywords

We are living in the era known as information era where numerous sectors especially health sectors are put to handle tremendous amount of information. To reduce this burden, an efficient data mining technology has been employed which is a successful evolving technique that has a big future for helping businesses and concentrates on the most valuable data in their data warehouses. Thus, this paper presents the review of Safe Semi Supervised Fuzzy C Means (S3FCM) clustering algorithm which is the key aspect of this work aids in achieving the goal. It has been utilized to cluster and classify the clear and relevant global data formats that many other clustering approaches unable to handle. By limiting the subsequent predictions obtained by unsupervised clustering, incorrectly labelled samples are thoroughly investigated. Meanwhile, the other labelled sample’s predictions are equivalent to the assigned labels. As a result, the labelled samples are safely examined using a combination of unsupervised clustering and Semi-Supervised Clustering (SSC). Therefore, it has been clear that S3FCM yields better result compared to other techniques. The Artificial Neural Network (ANN) based classification algorithm is used, which learns from the training dataset to construct a model. This model helps in the classification of new objects.Keywords
