Assessing the green behaviour []

In today's society and organizations, environmental protection has become critical. Natural disasters, climate change, and the loss of natural resources have all become a cause of concern. The destruction of forests, the combustion of fossil fuels, and the emission of carbon monoxide as a result of organizational and human activities are the causes of today's dire environmental situation. To counteract these effects, governments, especially those in developing countries, have pledged their support for global movements such as AGENDA 2030 and adopted policies encouraging businesses to adopt environmentally friendly practices. As a result, many businesses are focusing on implementing environmental management systems (EMS) or green programs to ensure that their everyday activities are less detrimental to the environment. Reduced carbon emissions, such as reduced energy and office materials use, and adequate recycling of materials are among these measures. Employee environmental efficiency and attitude are critical to the success of these green programs in businesses. It is wise to concentrate on improving the environmental skills, attitude, and behaviour of employees in order to improve an organization's environmental efficiency. A few air terminals experience serious clog probably a portion of the time, where 'blockage' implies that one airplane postpones the utilization of the air terminal or denies the utilization of the air terminal by another airplane in that time allotment. Essentially all financial experts acknowledge that when an asset is restricted, with the utilization of a framework that costs it to address its worth to any remaining expected shoppers, it very well may be dispersed most successfully. In any case, hypothetically, effective costs must be ensured if all organic market are cutthroat, markets are full (they permit any amount of exchanges whenever), and the members improve helpfulness by advancing benefit incomes.

Alpha and Beta []

Abstract The main problem in portfolio management is the question How an investor should distribute his wealth to gain the best possible expected return for the amount of risk, he is willing to suffer from. To solve this problem, Alpha is a measure of the performance of an investment as compared to a suitable benchmark index, such as the S&P 500. An alpha of one (the baseline value is zero) shows that the return on the investment during a specified time frame outperformance the overall market average by 1%. A negative alpha number reflects an investment that is underperforming as compared to the market average. Beta, on the other hand, is a measure of a stock's systematic risk or volatility.

An Effective Tea Leaf Classifier Using Faster R-CNN with Real-Time Object Detection []

Tea is one of the most significant beverages preferred all across the world and is undoubtedly a huge cash crop in the world, grown in climatically restricted geographic areas. The best Tea is prepared from the best Tea leaves grown under optimum conditions. Since the quality and the condition of the tea leaves is so vital in the Tea Industry as a beverage, the classification of eligible tea leaves that should be plucked has become an active area of research as the Tea Cultivation industry itself is facing threats due to lack of labor. This paper is mainly focused on classifying the 21-days old tender tea shoots from the younger buds. Images of the Tea Leaves are fed to the classifier from a mobile camera. This proposed approach consists of three phases such as preprocessing, classification to process the fed image and predictions through real-time Object Detection. The captured images are preprocessed using the Grabcut-image segmentation technique in order to introduce masking to support the followed labeling process. The Faster R-CNN model is trained with the labeled images to classify the leaves into 2 - classes, ready to be plucked and not-ready to be plucked. The trained model is experimented with video footage to provide prediction through real-time Object Detection. The experimental results of the tested tea leaf images proved that the proposed method classifies the tea leaves with an IoU of 0.670.


Preparing drilled well for completion and production requires comprehensive wellbore clean-up operation for all sections of the drilled well. Ineffective wellbore clean-up can result in formation damage and reduce the productive life of the well resulting in remedial and workover operation. Complete wellbore clean-up solution usually consists of a set of mechanical tools (scrappers, brush, junk basket, deburr tools, BOP jetting tool etc.), chemicals (cleaning surfactant spacer, transition spacer, etc), filtration equipment, and modelling software for the operation. An efficient wellbore cleaning solution would resolve wellbore cleaning challenge for the specific well within a considerable time frame leading to cost saving for the operator. To achieve this, different parameters and factors affecting wellbore clean-up are optimised experimentally and/or through modelling. Among these factors is the cleaning efficiency of the surfactant used for spacer formulation for well clean-up. These research analysis the performance of surfactants in wellbore clean-up operations considering contaminated and non-contaminated spacer condition. This work employed experimental approach to study the effect of the type of surfactant, RPM and flow rate, time and contamination in relation to the cleaning efficiency of the surfactant in unit of mud removal efficiency (%). Different surfactant samples were used for spacer formulation and their cleaning efficiency for cleaning/removing mud, varying the mentioned factors and analysing its effect on the surfactant cleaning efficiency. The study revealed that increasing the RPM, flow rate and reducing contamination results to higher cleaning efficiency with time. The different surfactant samples (A, B, C and D) also exhibited different cleaning efficiency with sample C yielding 98% and 95% mud removal after 4 minutes and 8.5 minutes contact time for non-contaminated and contaminated wellbore clean-up (WBC) test while Sample D cleaner surfactant resulted in 100% mud removal after 1.5 minutes for non-contaminated test. Sample C and D where the best performing surfactant sample among the alternatives.

Simulation and Optimization of Natural Gas Sweetening Plant []

This study is pursuing to quantitatively simulate an existing natural gas sweetening plant with a commercial process simulator (Aspen Hysys version10), using Peng Robinson as the fluid package. In this dissertation, one of the typical processes present in the natural gas chain were modelled: via chemical absorption with methyldiethanol amine, which has absorption selectivity of H2S preferentially to CO2 but for purpose of this project, the process parameter was modified to increase CO2 loading because the natural gas contain negligible amount of H2S. As the plant is considered new, there is a requirement to review the current plant operation and investigate any possible optimization and modification that can lead to reduction in the flared waste gases without violating the sweet gas specifications. Reduction of the operating costs and increasing the environmental sustainability of the process are two critical concerns in Greenville oil and gas. The plant operation was optimized by carrying out sensitivity analysis of the operating parameters (amine circulation rate and concentration simultaneously) which showed a decrease in CO2 loading in lean amine. Also, graph of mole fraction of CO2 in the sweet gas was plotted against amine circulation rate and amine concentration which showed a reduction in CO2 concentration in the sweet gas thereby meeting the liquefied natural Gas (LNG) specifications. It was found that increasing the absorption column temperature will increase the losses of water and amine to the sweet gas. There is a water loss of approximately 0.5 kmol h-1 for every 5°C increase in temperature. So, it is recommended that sensitive temperature difference between feed gas and the amine should be establish to eradicate excessive rich amine loss to the sweet gas at the top of the column. Also, it is recommended that, to avoid any condensation of light hydrocarbons which can cause foaming. So, a flow rate difference of at least 7m3/h should be establish between the feed gas entering the contactor and the amine in a counter current manner. The result of this work shows that at circulation rate of 22.7m3/hrs and concentration of 45% yielded the optimum natural gas composition (CH4 = 91.4, C2H6 = 3.3459, C3H8 = 2.7336, i-C4H10 = 0.5784, n- C4H10 = 0.8530etc) required for LNG production.
