Electronic and mechanical design of high-stability piezoelectric energy harvesting title

Paper ID- AMA-10-02-2023-12007

Piezoelectric energy harvesters are promising for converting the power of pedestrian footsteps or car moving on the road in to electricity. However, existing piezoelectric energy harvesters have limitation of poor durability. In this paper, to overcome that issue, a piezoelectric energy harvester using a flexible piezoelectric sensor is designed and fabricated in a tile protype with the indirect-touch points and a protective spring. The electrical output of the proposed harvester is examined as a function of pressure, displacement, and load resistance. The maximum output voltage and maximum output power are obtained to be 6.8 V and 4.5 mW, respectively at a pressure of 70 kPa, a displacement of 2.5 mm, and a load resistor of 15 k. The designed structure brings about the limitation of destroying risk piezoelectric sensor during operating. As a result, the harvester tile can work properly even after 500 cycles. Furthermore, for demonstration of practical application, the tile is putted on the floor of the overpass and walking tunnel. The electrical energy harvested from the pedestrian footsteps can power up a LED lighting.

Analyzing simulation-based adaptive type-I progressive hybrid censored competing risks data from step stress partially accelerated life testing in agricultural machinery

Paper ID- AMA-10-02-2023-12006

The advancement of new technologies has highlighted the need for a more precise assessment of the life of goods and systems before allowing them to serve in the market. Due to time and cost constraints, tests must be able to generate rapid and reliable life information, which is not attainable using conventional life testing methods. As a result, various censorship schemes, along with accelerated life testing, in which goods are subjected to increased stress in order to determine the life characteristics of products and systems in a short period of time, have been deemed significant tools. In addition to reducing product testing time through the use of accelerated life testing and various filtering techniques, understanding the impact of failure reasons is critical. In order to get precise failure information, the observer must distinguish between various failure causes. The current work aims to quantify the amount of information accessible for test item lifetimes by employing step-stress partly accelerated life tests with competing risks (CR) based on an adaptive type-I progressive hybrid censoring scheme (AdTI-PHCS). The Rayleigh distribution is used to explain the distribution of test item lifespans. To get point and interval estimates, the maximum-likelihood estimation (MxLE) approach is implemented. Moreover, to assess the performance of the given model parameters, a Monte Carlo simulation approach is utilized.

Estimation of Gene Action, Genetic Heritability, and Heterosis for Quantitative Traits in Melon (Cucumis melo, L.)

Paper ID- AMA-09-02-2023-12005

Melon is one of the most beloved healthy food crops worldwide that needs to increase its production and quality. This study was designed to estimate heterosis, combining abilities, gene action, and heritability in hybrids of melons to develop their yield and quality. The half-diallel cross method was used to produce six F1 hybrids driven from four inbred lines in a randomized complete block design (RCBD) with three replications. The hybrids and their parents were evaluated at the El-Gemmeiza Agriculture Research Station, Horticulture Research Institute, Agriculture Research Center, Egypt. The results revealed that the majority of the crosses had significant heterosis over the midparents, with better parent and chick hybrids for the majority of the traits. The highest significant heterosis over mid parents was 135:15%. The cross P1 x P3 was recorded for average fruit weight, followed by total yield / plot (108.97%). Analysis for combining ability indicated that GCA and SCA variances were highly significant. The ratios of GCA/SCA for all traits were lower than unity. The results reported that none of the parents showed either the best combiner or the best specific combiner for all traits. The broad-sense heritability magnitudes for number of leaves / plant and plant length traits ranged from 83.06 to 99.96%, while the narrow-sense heritability values ranged from 0.42 to 74.08% for total yield / plot and number of fruits / plot traits. These results indicate that selection may be more effective for improving traits in genotypes in early generations.

Instrumental Textural Profile Analysis of Tomato with different stage of maturity

Paper ID- AMA-09-02-2023-12004

Texture is perilous to the appropriateness of fruits and vegetables, both fresh and cooked. Textural properties data of tomato are important in adoption and design of various handling, packaging and transportation systems. Textural properties namely, bio yield point, flesh firmness, fracture energy and total energy were determined with respect to maturity stage under immature, mature and over mature situations as well as storage temperatures under ambient condition (25o C) and low temperature condition (6o C). The bio yield point (kg), flesh firmness (kg), fracture energy (kg.s) and total energy (kg.s) decreased with different stage of maturity, storage period and temperature of tomato was significant at 5 per cent level.

Productivity, profitability and soil health assessment of rice-green gram-maize cropping sequence under different sowing dates and nitrogen management in rainfed upland condition of Assam

Paper ID- AMA-09-02-2023-12003

A field experiment was conducted during 2016–17 and 2017–18 to assess the productivity, profitability and soil health of a rice-based crop sequence under different sowing dates and nitrogen management. The experiment was laid out in a factorial randomized block design with three replication. The treatment consisted of four dates of sowing for rice, green gram, maize, and four N management practices. Early sowing of rice, green gram and maize, combined with applications of 50% nitrogen as inorganic plus vermicompost @ 1.0 t/ha, resulted in a significantly higher grain yield. Performance on the crop sequence as a whole showed that early sowing of the crops produced the highest rice equivalent yield (REY), production efficiency (PE), land utilization efficiency (LUE), nutrient use efficiency (NUE), net return and B C ratio compared to later dates of sowing of the crop in the sequence. Application of 50% N as inorganic along with vermicompost @ 1.0 t/ha recorded significantly higher productivity, profitability and efficiency indices as compared to other treatments. There was maximum improvement in soil health indices with respect to organic carbon, microbial biomass carbon and soil microbial populations when inorganic nitrogen sources were combined with organic sources.
