In terms of competitors, spectators, and media interest, cricket is one of the favorite international sports. At the international level, cricket may be played in three formats: a five-day Test, a one-day International (ODI) for each squad of 50 overs, and a Twenty-Twenty (T20) for each team of 20 overs. Various online games that are based on the aforementioned cricket forms allow players to form a virtual squad of real-life players and score points based on how well they perform in real matches. A user gains better rank on the leaderboard if they get the most points in all of the contests they have participated in. Dream11 is one such online gaming platform which offers free and paid contests and thereby gamers can win some cash rewards. So users can select the eleven players and form a team. These eleven players should be selected from the two teams between which the match will be played. Additionally, these eleven players may be chosen from either one team or a combination of the two teams. To identify the eleven players for the T20 cricket format who can provide the maximum score to get the best rank in competitions, many studies employ Multi Criteria Decision Making (MCDM).In this paper, the TOPSIS method is utilized (weights of the performance factors of players are evaluated by using AHP) to determine the top eleven players.

This paper describes the adaptive optimal control of the inventory production system with Weibull-distributed deterioration items. First of all, the dynamic model of the system is presented with all possible disturbances and uncertainties. Then, it is controlled using an adaptive and optimal controller. In this method, by having numerical data from the output of the system without using its dynamic equations, an LQR controller is estimated for it. This is important and practical because in physical systems under significant disturbances and fundamental uncertainties, the dynamic equations of the system will not have the former reliability; And it is possible to change the equations of motion by adding any non-linearity so that the conventional controllers will suffer an error. Finally, it is shown that due to the nature of the system and existing uncertainties, the used method has a clear advantage over other optimal control methods and their application in optimizing the inventory production system in the supply chain.

The primary objective of this study was to investigate the effectiveness of an intervention program implemented in Saudi Arabia, aimed at equipping children diagnosed with autism spectrum disorder (ASD) with essential self-care skills. The research employed a quasi-experimental design, encompassing both an intervention group and a non-intervention group. The results of the study revealed that following the implementation of the intervention, the experimental group exhibited a noteworthy enhancement in their self-care capabilities in comparison to the control group. The results of the study revealed a noteworthy disparity in the post-test scores between the experimental group and the control group, thus providing compelling evidence for the effectiveness of the training program in fostering the development of self-care skills. The findings align harmoniously with previous research endeavors that have explored effective strategies for enhancing self-care skills among children diagnosed with autism spectrum disorder (ASD). The intervention demonstrated a commendable display of cultural sensitivity by duly considering the intricacies of Saudi Arabian culture, which places great value on the significance of familial and communal bonds. The efficacy of the intervention can be attributed to its astute consideration of cultural norms and its inclusive approach involving parents and other caretakers. The results of this study suggest that the integration of culturally appropriate modifications to evidence-based interventions holds promise in facilitating the development of self-sufficiency and improving the overall quality of life for children diagnosed with autism spectrum disorder (ASD). The study's limitations, including its modest sample size and absence of extended follow-up, warrant further inquiry into strategies to enhance the study's robustness and applicability.

In Dubai, the government alone cannot bring about economic development and provide jobs to all and sundry. Businesses established by individuals and corporate entities aid the government in the provision of jobs to people and contribute to the economic growth and development of a country. The role of SMEs is crucial in most of the countries of the world and they contribute significantly towards provision of employment opportunities in their local communities and development of their economies. The main objective of this study is to examine the factors influencing the performance of SMEs in the UAE. The findings from the analysis found that technological factors and environmental factors have a positive and significant impact on SMEs performance. This study has a significant contribution to the body of literature as it provides a worthy theoretical framework in it. Besides theoretical contribution, this study also provides practical implications to SMEs, government and policymakers. The future direction of this study would enhance the future body of literature.

This paper analyses the impact of economic policy uncertainty at the firm level on the inconsistency of words and actions in their digital transformation. Using new quantitative indicators of the gap as well as robust models, we find that firm economic policy uncertainty can exacerbate the gap between what firms say and do about digital transformation. In light of these findings, the paper concludes that there tends to be a certain amount of digital transformation hype among listed firms.

Manual labour in slaughterhouses is hazardous work. Workers suffer from injuries and occupational illnesses resulting from repetitive movements with sharp knives. There is a need for a robotic tool which can perform versatile tasks with a high level of precision. This knife must be able to imitate the same primary cuttings of a professional butcher and produce meat products which are acceptable to the end-market. This paper reports the results of a world-wide assessment of the fresh pork meat cuts as a performance indicator of knives specifically adapted for automated operation. These knives included Victorinox knife, bespoke double bladed Uddeholm knife, vibrating knife and novel smart knife with built-in sensing mechanism that detects in real time the contact with meat and cut depth. Physical appearances of cuts were assessed anonymously by independent responders with different backgrounds. All knives were deemed acceptable in terms of cutting quality. There was also no discernible difference of opinion between manual and robot cuts. This indicates that the new knife for robot-assisted cutting is acceptable by market.

In this manuscript, the mean of the study and the auxiliary variable, as well as the rank of the auxiliary variable, were needed to develop a new, improved ratio-in-regression type estimator for population mean. Up to the first order of approximation, expressions for the bias and mean square error of the existing and proposed estimators are computed. The effectiveness and stability of our new, enhanced estimator are evaluated using simulation and two actual data sets. The suggested estimator's superior performance to all other considered estimators is shown both conceptually and numerically. The mean square error is the lowest, and PREs out-performs other known estimators by a factor of more than one hundred. Overall, we draw the conclusion that the suggested new improved estimator outperforms all its predecessors.
