S Juzar, M Sivalingam , (2020), -"Automated greenhouse monitoring and control system", 209 – 214,

Greenhouse is a structure used to grow crops, in which environmental factors are controlled to provide an ideal setting for crop growth. Decision making done by humans to deliver these ideal conditions is not reliable since an accurate measure of environmental parameters cannot be provided. Relying fully on weather forecast is also not recommended especially for areas where the weather conditions are uncertain. This would lead to human error, and thus decrease the reliability. In addition, it would cause the crops to go bad or develop a disease, wasting resources that have been used to mature the crop to that level. Furthermore, humans cannot be relied on 24/7 to ensure the essential conditions are being met as this puts a strain on labourers. This causes crop quality and yield to decline, and in turn increase food wastage at the production level. Thus, the rationale behind automating the process of a greenhouse using a robot will increase yield and quality of the crops, ensure resources are used efficiently and decrease food wastage at the production level. Additionally, it will compensate for limitations in the existing systems by allowing the user to change the threshold values. This is a beneficial feature because growers commonly grow different types of crops in a greenhouse, or want to replace a crop once its lifetime is over. The autonomous robot will sense the environmental parameters of the greenhouse, and accordingly the actuators in the control system will function and also depending on the threshold values sent through SMS it allows the user to change the threshold values of the actuators in the control system.

A A E Madhushan, A M Welhenge, M Sivalingam , (2020), -"Arduino based automatic option control unit for electric sewing ", 87 – 94,

Modern electric sewing machines are having more electric and electronic applications than mechanical applications. But, due to the long-term operation and improper usage certain electronic issues can occur in these machines. Besides, there may be mechanical errors as well. Most of the garment factories are having their own repair centre to repair their machines. After repairing a machine, those machines should be tested for 45 minutes to ensure the sewing machine is production

floor worthy. In some of the sewing machines there is an in-built auto run parameter which sets the machine to autorun mode and the machine is tested in this mode after repairing. There are many brands of electric sewing machines in which this parameter is unavailable. As a solution for this problem a prototype is designed and implemented to test machines after doing a repair as per the manufacturer’s recommendation. The test kit designed is named as AOC unit which stands for Automatic Option Control unit. This option controlling unit is designed to install to any sewing machine externally and the servo motor used in the unit is attached to the speed controller of the sewing machine. Sewing machine speed controller has been designed by the manufacturer to provide command signals to the microprocessor when the pedal position is changed by the operator. AOC unit actuates the speed controller without any interference of the operator and sewing machine operates

automatically within a given time. This operation is stopped by the countdown timer in the unit at the end of the set time.

Nivarthana D.G.S, Abeyrathna W.A.M.I., (2022), -"The country of origin effect on undergraduate purchase intention: Special Reference to imported shopping goods",

Country of Origin and purchase intention are highly connected in the global marketing context because, in the modern era, the consumers’ (undergraduates) purchase intention depends on the country of origin. The main objective of this research is to identify the country of origin’s effect on undergraduate purchase intention. The paper has conducted with particular reference to imported consumer goods for undergraduates in Horizon Campus. The country of origin effect on undergraduate purchase intention was identified under 19 indicators, including 14 for country of origin (Independent variable) and 5 for purchase intention (Dependent variable). The sample of 300 students was selected using the simple random sampling technique, and data were collected using a standard questionnaire to identify the country of origin on undergraduate purchase intention. In this study, Cronbach’s alpha value ensures the questionnaire’s reliability. Furthermore, SPSS 25 version was used to analyse the data. The data were analysed using mean, correlation, and regression analysis. Correlation analysis was used to identify the relationship between country of origin and undergraduate purchase intention. According to the hypothesis developed, it can be concluded that the relationship between country of 0oigin and undergraduate purchase intention. According to the research findings, there is a positive relationship between the two variables. Based on the study results, it can be concluded that purchase intention can be changed with the country of origin. These research findings will be beneficial for the decision-makers to make better decisions according to their preference and save the cost.

Balamanage D.A, Abeyratna W.A.M.I., (2022), -"Impact of Self-Congruence on emotional brand attachment of undergraduates: With special reference to smartphone brands in Sri Lanka",

The purpose of this research is to examine the impact of self-congruence on the emotional brand attachment of undergraduates: with special reference to smartphone brands in Sri Lanka. In this study, data were collected using self-administered questionnaires through snowball sampling to identify the impact of self-congruence on the emotional brand attachment of undergraduates. The sample comprised 331 undergraduates. Data were analyzed using Mean, Correlation and Regression Analysis. The study findings of this research interpret that the effect of actual self-congruence on emotional brand attachment is lower than the effect of ideal self-congruence on emotional brand attachment. As per regression analysis, self-congruence has a significant positive impact on emotional brand attachment. The findings of this study support the view that self-congruence can increase emotional brand attachment. The findings of the paper led to some important theoretical and managerial implications for researchers and practitioners in the smartphone industry in the South Asian context.

M S A Azeez, W A M I Abeyratna, (2020), -"The Impact of Personal Selling on Buying Behavior with Special Reference to Clothing Stores in Sri Lanka", The IUP Journal of Marketing Management, (Volume 19),

Personal selling and buying behavior are areas of interest in the global marketing context.
Businesses need to identify the correct techniques for personal selling with the aim of
influencing consumers’ buying behavior. The main objective of this study is to identify
the impact of personal selling on buying behavior. The study has been carried out with
special reference to clothing stores in Sri Lanka. The impact of personal selling on
buying behavior is identified under four dimensions, namely, salespersons’ personal
characteristics, presentation of commodities (goods) by salespersons, characteristics of
clothing sale stores and promotion conducted by the salespersons in clothing sale stores.
For this study, 322 undergraduate students were selected as the sample using the simple
random sampling technique. Furthermore, SPSS 25 version was used to analyze the
data. Regression analysis was utilized to test the hypotheses of the study. The results of
the study found that there is a significant positive impact of salespersons’ personal
characteristics, characteristics of clothing sale stores and promotion conducted by salesperson
in clothing sale stores on the buying behavior. However, no impact of presentation of
commodities (goods) by the salespersons on buying behavior has been found.

W.A.M.I. Abeyratna, Dr. B.J.H. Arachchige, (2019), -"Impact of Envy on Emotional Engagement: A Study of the Academic Staff Members in the Private Higher Education Sector in Sri Lanka", IOSR Journal of Business and Management, (Volume 21),

Employees are emotional beings. Therefore, it is difficult to suppress the emotions of an employee throughout the work time, though it is sometimes intentionally required. Naturally negative emotions in the workplace are neglected even though positive emotions tend to get reinforced with ease. In addition, emotional engagement is also an important topic in management and psychological literature. People who are engaged in their jobs are driven by enthusiasm and pride towards the job. Even though there are various factors which directly influence emotional engagement, this research focuses only on envy as an emotion and its impact on emotional engagement as envy is a factor which has received less scholarly attention. Therefore, this study presents envy that is one of the rampant negative emotions in the workplace and its impact on emotional engagement. The study was conducted on a sample of 162 academic staff members working as full time academics in private higher educational institutes in the Colombo District of Sri Lanka. The data was analysed using Statistical Packages Social Sciences (SPSS) version 20. Results of the study found that there is a significant impact of feeling envied by others and feeling envious of others on emotional engagement. Moreover, the study illustrated that feeling envied by others and feeling envious of others is negatively associated with emotional engagement. Accordingly, the findings have proposed managing employee envy is worthwhile as it leads them to better engage themselves in their jobs emotionally.
