Characterization of Performance Anomalies in Hadoop

With the huge variety of data and equally large-scale systems, there is not a unique execution setting for these systems which can guarantee the best performance for each query. In this project, we tried so study the impact of different execution settings on execution time of workloads by varying them one at a time. Using the data from these experiments, a decision tree was built where each internal node represents the execution parameter, each branch represents value chosen for the parameter and each leaf node represents a range for execution time in minutes. The attribute in the decision tree to split the dataset on is selected based on the maximum information gain or lowest entropy. Once the tree is trained with the training samples, this tree can be used to get approximate range for the expected execution time. When the actual execution time differs from this expected value, a performance anomaly can be detected. For a test dataset with 400 samples, 99% of samples had actual execution time in the range predicted time by the decision tree. Also on analyzing the constructed tree, an idea about what configuration can give better performance for a given workload can be obtained. Initial experiments suggest that the impact an execution parameter can have on the target attribute (here execution time) can be related to the distance of that feature node from the root of the constructed decision tree. From initial results the percent change in the values of the target attribute for various value of the feature node which is closer to the root is 6 times larger than when that same iii feature node is away from the root node. This observation will depend on how well the decision tree was trained and may not be true for every case

An Assessment of Indoor Air Quality (IAQ) in Metal industries of Delhi

With growing realization and concern for our health, the focus on Indoor Air Quality has increased. Exposure to indoor air pollution is responsible for nearly 2 million excess deaths in developing countries and for some 4% of the global burden of disease. Today it is critical that the industry be familiar with the environmental hazards that employees are subjected to in the workplace. Iron & steel and other manufacturing industries, foundries and forges produce a lot of pollutants in the indoor environment. Exposures to mineral dusts, metal fumes, products of combustion, resin bonding systems, physical noise and heat and vibration hazards may seriously impact the health of workers in foundries. The study aimed at assessing Indoor Air Quality in Metal industries of Delhi in Mayapuri industrial area. The study was carried out in 3 phases. In the first phase, the study collated awareness about Indoor Air Quality and related health effects amongst the owners and employees working in the enterprises. In the second phase, the study involved monitoring of the randomly selected enterprises in terms of CO2, PM2.5, PM10 and presence of dampness and molds in the enterprises. The third phase involved spreading awareness regarding Indoor Air Quality amongst the sample. Highlights of the study are: Majority of the owners were aware about the concept of Indoor Air Quality and its relationship with productivity and health of a person. They could also cite some of the health impacts caused due to poor Indoor Air Quality. In spite of their wisdom on Indoor Air Quality, there were no monitoring and maintenance provisions in their enterprises. Also, none of the owners provided their employees personal protective equipment (PPE) and any information or training regarding Indoor Air Quality and its health hazards. Majority of the employees were unaware of the concept of Indoor Air Quality. The employees could neither relate health with Indoor Air Quality nor showed any interest in improving the same. It was seen that there was a moderately high level of CO2 concentrations in the enterprises, mainly due to insufficient ventilation in the enterprises. PM2.5 concentrations were found to be poor and were almost double than its acceptable limits. While it was seen that PM10 concentrations were within their acceptable limits. It was observed that in majority enterprises presence of molds and dampness was observed. It was observed on walls and ceilings. The areas near the walls and places with molds were surrounded by a bad odor. This study has been helpful in providing clear direction towards the Indoor Air Quality in Metal industries operating in Mayapuri. It also highlights the awareness regarding Indoor Air Quality amongst the sample. The study concludes that there is a sense of knowledge regarding Indoor Air Quality amongst the owners/managers of the enterprises but a huge scope in monitoring and maintenance provisions. The need for spreading awareness about IAQ and its related health effects were highlighted which would improve Indoor Air Quality in industries. The study showcased a clear scope for awareness generation and training amongst the owners and employees of the enterprises regarding Indoor Air Quality. The study suggests surveying of health status in metal industries and similar research in other industries. The findings were also shared with competent authorities to sensitize them towards poor Indoor Air Quality in the metal industries

Comparative Study of Online and Offline Shopping: A Case Study of Rourkela in Odisha

The study tries to recognize that, how consumer measure channels for their purchasing. Specifically, it progresses a conceptual model that addresses consumer value perception for using the internet shopping versus the traditional shopping. Earlier study showed that perceptions of price, product quality, service quality and threat strongly impact perceived value and purchase intents in the offline and online network. Observations of online and offline buyers can be evaluated to see how value is constructed in both channels. It is hitherto to recognize what factors influence online and offline shopping choice progression. The objective of this study is to provide an impression of online shopping decision process by comparing the offline and online decision making and identifying the factors that motivate customers to decide whether to do online shopping or go for the offline shopping. Consumer’s shop when and where they want, where they are comfortable with the products and the choice of shopping. The study finds that female are more into online shopping than male. Since last two years as population are more aware of the technology the online shopping increased immensely. The people from the age group 35 and above are less likely to do online shopping because they are less aware of the technology. However the respondent said that they will love to purchase from online shopping if only the price of the product is less than the market. They revealed that it is fairly important to go for e-shopping

Effect of paclobutrazol and benzyl adenine on oriental lily hybrids

Studies on the effect of growth regulators viz., Paclobutrazol and Benzyl Adenine (PBZ and BA, respectively) on Oriental Lily Hybrids, 'Star Gazer Pink' and 'Star Gazer White' in the second year were carried out at Department of Floriculture and Landscaping, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P). The effect of growth regulators applied in the first year, was studied on growth and flowering of Oriental lily hybrids in the second year. Plant height and number of leaves plant-1 were recorded maximum when PBZ 25 ppm was applied in the first year. Maximum plant height and number of leaves plant-1 were found in 'Star Gazer White' (84.46 cm; 35.04 cm). Bulbs of 'Star Gazer White' when dipped in PBZ 25 ppm for 12 h in the first year resulted in maximum plant height (102.50 cm) in the second year. Leaf area in the second year was recorded maximum in 'Star Gazer White' (34.40 cm2) when PBZ 50 ppm was applied as bulb dip in the first year. Flower buds were initiated earlier in 'Star Gazer White' (84.48 days) as compared to 'Star Gazer Pink' (85.90 days). Days to bud initiation were also recorded minimum (75.81 days) when PBZ 25 ppm was applied as pre-plant bulb dip. More number of flowers plant-1 was recorded in 'Star Gazer White' (5.42) which lasted longer on stems (16.77 days). Bulbs dipped in growth regulators in the first season produced maximum number of flowers plant-1 (5.72) and duration of flowering was also maximum (18.28 days)

Seasonal Variation of Tropospheric Ozone and Its Association with the Chemical and Meteorological Precursors in Delhi, India

In the present study, profile of tropospheric ozone and its variation with its chemical and meteorological precursors has been assessed in Delhi. The ambient air of Anand Vihar ISBT was found to be mainly dominated by NOx (335 ug/m3) and BTX (Benzene-12.2 ug/m3, Toluene -37 ug/m3 and pXylene -8.2 ug/m3) amongst the selected sites of Delhi. NOx was found to be predominately high due to high vehicular traffic, fireworks during festivals and crop burning in and around Delhi during November 2015. The concentration of benzene was exceeding the permissible standards in all the selected sites of Delhi. The study also revealed that the highest annual concentration of tropospheric Ozone (56.2 ± 23.5 ug/m3 ) was reported from Punjabi Bagh among the selected sites of Delhi and was recorded primarily in summers (March 2016-June 2016). The results indicate that higher temperature, lower humidity and high intensity of solar radiation contribute to the formation of tropospheric ozone in Delhi. The minimum concentration of ozone was recorded during the monsoons (July, 2016-September, 2016). This indicates the high humidity, large cloud cover, low intensity of solar radiation which could have been the reason for slowdown of the photochemical process. A positive correlation was observed between tropospheric ozone and ambient temperature in Delhi

However head formation was earliest (158.53 days) in 1 December planting

Evaluating the Impact of AI-Based Sustainability Measures in Industry 5.0: A Longitudinal Study

In the context of Industry 5.0, this long-term study assesses the significant influence of AI-based sustainability metrics. It also illuminates a novel paradigm in which artificial intelligence (AI) and human expertise work together to jointly drive sustainability, financial performance, employee satisfaction, and overall ecological responsibility. AI-driven sustainability efforts produced a surprising 12% reduction in trash creation, an amazing 7% reduction in energy usage, and an 8% drop in CO2 emissions over a five-year period. Financially speaking, these actions showed up as a steady 4% annual revenue growth, $2 million in cost reductions on average each year, and a cumulative 3.4% gain in return on investment. The human factor is even more notable, with employee satisfaction ratings rising from 4.2 to 4.7 and work-life balance scores significantly rising from 4.1 to 4.6. By 2024, 70% of workers will have adopted AI, demonstrating how essential AI has become to the working. An all-encompassing sustainability score that included these dynamic components increased from 60 to 75 in 2024, indicating a general improvement in sustainability. This study emphasizes the mutually beneficial relationship between artificial intelligence (AI) and sustainability in Industry 5.0. It shows how AI fosters a sustainable and balanced industrial future by improving environmental responsibility and workforce satisfaction while also producing significant financial benefits

Development of an EGFRvIII specific recombinant antibody

<p>Abstract</p> <p>Background</p> <p>EGF receptor variant III (EGFRvIII) is the most common variant of the EGF receptor observed in human tumors. It results from the in frame deletion of exons 2-7 and the generation of a novel glycine residue at the junction of exons 1 and 8. This novel juxtaposition of amino acids within the extra-cellular domain of the EGF receptor creates a tumor specific and immunogenic epitope. EGFRvIII expression has been seen in many tumor types including glioblastoma multiforme (GBM), breast adenocarcinoma, non-small cell lung carcinoma, ovarian adenocarcinoma and prostate cancer, but has been rarely observed in normal tissue. Because this variant is tumor specific and highly immunogenic, it can be used for both a diagnostic marker as well as a target for immunotherapy. Unfortunately many of the monoclonal and polyclonal antibodies directed against EGFRvIII have cross reactivity to wild type EGFR or other non-specific proteins. Furthermore, a monoclonal antibody to EGFRvIII is not readily available to the scientific community.</p> <p>Results</p> <p>In this study, we have developed a recombinant antibody that is specific for EGFRvIII, has little cross reactivity for the wild type receptor, and which can be easily produced. We initially designed a recombinant antibody with two anti-EGFRvIII single chain Fv's linked together and a human IgG1 Fc component. To enhance the specificity of this antibody for EGFRvIII, we mutated tyrosine H59 of the CDRH2 domain and tyrosine H105 of the CDRH3 domain to phenylalanine for both the anti-EGFRvIII sequence inserts. This mutated recombinant antibody, called RAb^DMvIII, specifically detects EGFRvIII expression in EGFRvIII expressing cell lines as well as in EGFRvIII expressing GBM primary tissue by western blot, immunohistochemistry (IHC) and immunofluorescence (IF) and FACS analysis. It does not recognize wild type EGFR in any of these assays. The affinity of this antibody for EGFRvIII peptide is 1.7 × 10⁷M^-1as determined by enzyme-linked immunosorbent assay (ELISA).</p> <p>Conclusion</p> <p>This recombinant antibody thus holds great potential to be used as a research reagent and diagnostic tool in research laboratories and clinics because of its high quality, easy viability and unique versatility. This antibody is also a strong candidate to be investigated for further in vivo therapeutic studies.</p
