The probability models of two and three mixed gamma distributions, specifically the Lindley and Sujatha distributions, will be enhanced through the application of random variable transformation techniques, resulting in the Power Lindley and Power Sujatha probability models. This study employs four probability models: Lindley, Sujatha, Power Lindley, and Power Sujatha, to analyze the survival time of diabetic patients. All probability models in this study will utilize the maximum likelihood method for parameter estimation. The optimal model will be determined based on a goodness-of-fit test, which will incorporate both graphical methods (density and cumulative distribution graphs) and numerical methods (Akaike's Information Criterion (AIC) and negative log-likelihood). The results of the goodness-of-fit test indicate that the model derived from the random variable transformation yields a superior probability model compared to its original form.

Specific instability of boreholes drilled through rocks, such as borehole breakout, borehole collapse, and shale swelling, is a significant concern in drilling operations due to the adverse impact it has on drilling safety and efficiency. Despite considerable research on borehole instability, finding a solution to this problem remains elusive. The objective of this review is to examine the primary mechanisms of instability in rocks from a general physical instability principle perspective. A key criterion for the analysis of specific instability problems is the construction of comprehensive phase diagrams. Within this context, three main approaches and their partial implementation are discussed. The first approach involves constructing phase diagrams under the assumption that the borehole has already caved and aims to determine the final position of the cave wall. However, this approach presents several challenges. Caving may lead to severe kick-off or break-off problems, instability during the caving process, and complications in simultaneously modeling caving in a fluid-like porous material alongside flow filtration through the open walls of the borehole. The second approach entails developing phase diagrams that characterize the mechanical and hydraulic instability of the borehole wall being driven. These phase diagrams serve as specific instability criteria, but they face difficulties in generalizing across various failure mechanisms since they are typically non-quasi-static and are disregarded after failure occurs and the propagation ban is implemented. The third approach involves analyzing phase diagrams to investigate the results of the touch modes of compliance. However, these phase diagrams and the collapse of final boundary conditions often overlook the main depletions and in-situ impedances, which are crucial system-specific physical complements that enhance the classical mode of balance equation. Therefore, the integration of these factors is essential for a more comprehensive understanding of borehole instability.

Consequently, the following conclusions could be drawn from the research of the sources provided. Multimedia is a relatively new concept in the teaching and learning process, and different people have given it varied definitions. Some individuals only connect multimedia with computer-based education. But without any doubt it goes beyond this. The word ‘multi’ in multimedia means ‘many’, this has a implication that many media are combined together to form one media of teaching and learning which is done through use of the PC [1, 2, 11, 13]. The pc develops into function as the compiler. The other word that would be used is ‘interconnection’ of different media to form a single medium. This is capable of being talked about in details later. “Multimedia” is a phrase which may be defined as one that is currently popular among educational technologists. Unless its meaning is specified, the term may mean “a wise blend of different mass media including print, audio and video” or it will mean the development of computer technologies that are mass-produced and yet still provide options for individual utilization when it comes to acquiring knowledge. In other words, multimedia combines various forms of learning into an academic device that allows the plurality of approaches to curriculum delivery. “Multimedia is that the enthralling interconnection of hardware and software which allows one to use video, animation, audio, graphics and test resources to create competent presentations for a reasonable desktop”. “Multimedia is defined as the system that includes or can include text, pictures, sound, animation and video, of which one or several are structured in some kind of program”. Multimedia of today may well be an intricately designed and executed blend of words, graphics, music, texts and visuals, animation and video. as soon as one permits an user or the viewer of a multimedia project to control ‘what’, ‘when’ and ‘how’ of the weather that are being brought and presented then it becomes hypermedia.

Visual Basic provides a variety of tools and features that facilitate the design and construction of an electronic archiving system in an effective and integrated manner, which increases the efficiency and effectiveness of the archiving and data management process. In Visual Basic, electronic archiving applications can be seamlessly integrated with existing systems in the organization, which reduces confusion and disturbances in daily operations. The work focuses on designing and implementing an electronic archiving program based on Visual Basic. We have built a highly efficient program based on Visual Basic to organize electronic archiving with the aim of saving effort and time for workers in the archiving units for official documents and correspondence. Through the research, we demonstrate the ability of Visual Basic to transform paper mail work into electronic archiving characterized by transparency, speed, and no delay in delivering documents and preserving them from damage due to their storage in the database and the possibility of retrieving them at any time. It also reduces the burden on people responsible for archiving, mail and documents. Visual Basic's API can be easy to use and suitable for non-tech-savvy users. The cost of building and designing electronic archiving applications using Visual Basic can be lower compared to custom development solutions or using off-the-shelf commercial systems, reducing capital expenditures.

This paper explores the influence mechanism of artificial intelligence application on corporate green innovation with a sample of A-share listed companies in Shanghai and Shenzhen from 2010 to 2023. It is found that artificial intelligence application is significantly positively related to corporate green innovation. After robustness tests such as replacing core variables, excluding new crown epidemics, and excluding green innovation outliers, the finding remains unchanged, indicating that AI application significantly promote corporate green innovation. Further analysis reveals that the promotion effect of AI application on corporate green innovation is more obvious in high management shareholding ratio and non-heavily polluted enterprises, while it does not show a significant difference in the nature of ownership and industry attributes. The findings of this paper not only enrich the existing literature on AI application, but also provide empirical evidence on how governments can promote corporate green innovation.

This study examined the probability of death using survival data of individuals with diabetes. The main objective of this study was to identify the most appropriate distribution to represent the survival time of patients with diabetes from 50 individuals in the Bengkalis area using 1-parameter probability modeling, such as the Lindley (LL), Sujatha (SJ), Amarendra (AR), Devya (DV), and Shambhu (SB) distributions. The maximum likelihood method was used to estimate the parameter values of the distributions used in this study. In addition, graphical assessment (density-density plots) and numerical criteria (Akaike’s Information Criterion (AIC), -2 log likelihood (-2*l)) will be used to determine the most appropriate model. In most cases, the results obtained from the graphical assessment were consistent but differed from the numerical criteria. The model with the lowest AIC value (-2*l) is selected as most appropriate. Overall, the Amarendra and Devya distributions were identified as the most appropriate models.

Due to the ever increase in energy demand, it becomes imperative to design appropriate reactor for the conversion of available raw materials to energy source such as bio oil. A fluidized bed reactor is one the most promising reactor for the conversion of biomass to bio-oil via pyrolysis. This work take into consideration the design of fluidized bed reactor and its subsidiaries (cyclone, filter, condenser and feed hopper) to be used for bio-oil production using sawdust as the feedstock. The operating conditions were temperature between 400-6000C, pressure 9.9atm and flow rate 1.86m/s. From the design calculations, it was found that the volume of the reactor, area, height, diameter and minimum fluidized velocity were 15.0796mm3, 5026mm2, 300mm, 80mm and 1.86m/s respectively. The material for construction for the reactor is stainless steel because of its high thermal conductivity and resistance to corrosion.
