Towards a DEVS Model Management System for Decision-Making Web Applications

The discrete event system specification formalism introduced by Zeigler in the 1970s is ideally associated with new technological advances in the web to offer an almost quasi-automatic mechanism for exporting its simulation models associated with experimental frames into web apps. In this paper, we show how, thanks to the association of certain current web concepts (cloud computing, application virtualization, etc.), discrete event system specification formalism makes it easier to develop web apps that use simulation models to assist decision-making. We propose a simulation model management system used by teams of data scientists, modelers, and developers (engineers) capable of building and deploying web applications from simulation models with minimal web development knowledge.

Adaptive technologies for rapid web interface design of corporate educational systems within the framework of the 1C:Enterprise 8.3 platform

The article discusses technologies for fast web application deployment design based on continuous information exchange with a corporate system developed using the 1C:Enterprise 8.3 platform. We identify data exchange formats between a web application and a software product based on the 1C:Enterprise 8.3 platform to handle the tasks of dynamically generated and adaptable interfaces. The study proposes the concept of a modifiable component-based architecture for the interaction of a web application with commercial data storage and processing systems. This concept makes it possible to implement a dynamic web application interface design and to automate the data management functionality directly from the enterprise solution based on the 1C:Enterprise 8.3 platform. The article formulates the criteria and operating principles for such an application. We have also developed system technologies to design a web application that can be integrated into replicated software solutions permitting control of the mechanisms for dynamic interface design and data transfer from the solution to a web application. The launched application for web application interfaces designing makes it possible to dynamically change the components of web forms as well as determine the details displayed to the user in the output interface. In addition, we describe the principles of dynamic interaction between a web application and the data interface management component. The research enabled us to identify the components of the module for interaction of interfaces with the web application. A conceptual universal control scheme for generating dynamic interfaces has been formulated. It can be implemented to create almost any kind of web forms, including processing incoming data from a web application using the REST interchange in JSON format. The article provides a comparison of interchange formats. We describe implemented IT-projects for organizing a prospective student’s personal account and the applicant’s dynamic rating.

Development and Deployment of Web Application Using Machine Learning for Predicting Intraoperative Transfusions in Neurosurgical Operations

Background and Aim: Preoperative blood product preparation is a common practice in neurosurgical patients. However, over-requesting of blood is common and leads to the wastage of blood bank resources. Machine learning (ML) is currently one of the novel computational data analysis methods for assisting neurosurgeons in their decision-making process. The objective of the present study was to use machine learning to predict intraoperative packed red cell transfusion. Additionally, a secondary objective focused on estimating the effectiveness of blood utilization in neurosurgical operations. Methods and Materials/Patients: This was a retrospective cohort study of 3,021 patients who had previously undergone neurosurgical operations. Data from the total cohort were randomly divided into a training dataset (N=2115) and a testing dataset (N=906). The supervised ML models of various algorithms were trained and tested with test data using both classification and regression algorithms. Results: Almost all neurosurgical conditions had a cross-match to transfusion ratio of more than 2.5. Support vector machine (SVM) with linear kernel, SVM radial kernel, and random forest (RF) classification had a performance with good AUC of 0.83,0.82, and 0.82, respectively, while RF regression had the lowest root mean squared error and mean absolute error. Conclusion: In almost all neurosurgical surgeries, preoperative overpreparation of blood products was detected. The ML algorithm was proposed as a high-performance method for optimizing blood preparation and intraoperative consumption. Furthermore, ML has the potential to be incorporated into clinical practice as a calculator for the optimal cross-match to transfusion ratio.

Thanks to the rapid development of the computing power of personal computers, network data exchange mechanisms, cloud technologies and Open Source software, it has become possible to use more complex and efficient approaches to architecture design and deployment of web applications, such as a service-oriented, microservice model and deployment on a virtual machine or cloud. Due to the emergence of a large number of new technologies described above, it is quite difficult to apply them effectively enough without proper experience, as well as to switch to new models of architecture design.

Tethys App Store: Simplifying deployment of web applications for the international GEOGloWS initiative

Portability of web applications between web servers of different organizations can be challenging and can complicate sharing and collaborative use of such tools. Given the distributed nature of the web, this lack of portability is usually not a concern because a user in one organization can link to and use a web application hosted by another organization. However, access control or differentiation may be needed by an organization in terms of area of interest, input data, analytical techniques, access control, presentation, branding, and language. This is true for many government organizations, and their associated web sites, and servers. In such cases, there are compelling political, branding, security, and privacy motivations that require each organization or agency to host and manage web applications on their own servers rather than using third party web sites over which they have little or no control. We present the design, development, and testing of a system for discovering, installing, and configuring environmental analysis web applications on localized web servers. The system works with applications developed using Tethys Platform, which is an open-source software stack for creating geospatially enabled web-based applications. The developed Tethys App Store includes a Tethys application user interface that allows a server manager to retrieve applications from the central repository and install them on a local server with relative simplicity, similar to the installation of a mobile application to a mobile device from a mobile application store. The system was developed to support deployment of water and environmental analysis web apps for the international Group on Earth Observations (GEO) Global Water Sustainability (GEOGloWS) initiative of the National Aeronautics and Space Administration (NASA) and several partner organizations.

Deep Learning-Based Autoscaling Using Bidirectional Long Short-Term Memory for Kubernetes

Presently, the cloud computing environment attracts many application developers to deploy their web applications on cloud data centers. Kubernetes, a well-known container orchestration for deploying web applications on cloud systems, offers an automatic scaling feature to meet clients’ ever-changing demands with the reactive approach. This paper proposes a system architecture based on Kubernetes with a proactive custom autoscaler using a deep neural network model to handle the workload during run time dynamically. The proposed system architecture is designed based on the Monitor–Analyze–Plan–Execute (MAPE) loop. The main contribution of this paper is the proactive custom autoscaler, which focuses on the analysis and planning phases. In analysis phase, Bidirectional Long Short-term Memory (Bi-LSTM) is applied to predict the number of HTTP workloads in the future. In the planning phase, a cooling-down time period is implemented to mitigate the oscillation problem. In addition, a resource removal strategy is proposed to remove a part of the resources when the workload decreases, so that the autoscaler can handle it faster when the burst of workload happens. Through experiments with two different realistic workloads, the Bi-LSTM model achieves better accuracy not only than the Long Short-Term Memory model but also than the state-of-the-art statistical auto-regression integrated moving average model in terms of short- and long-term forecasting. Moreover, it offers 530 to 600 times faster prediction speed than ARIMA models with different workloads. Furthermore, as compared to the LSTM model, the Bi-LSTM model performs better in terms of resource provision accuracy and elastic speedup. Finally, it is shown that the proposed proactive custom autoscaler outperforms the default horizontal pod autoscaler (HPA) of the Kubernetes in terms of accuracy and speed when provisioning and de-provisioning resources.

Fuzzy and Mathematical Effort Estimation Models for Web Applications

This paper proposed an Effort Estimation Model for optimizing the deployment of Web Applications Based Fuzzy and Practical Models. Fuzzy logic approach is applied for estimating the development effort, which is compared with practical efforts model in the development process with interpreting the historical data available for the existing functionalities. This paper presented effort estimation model that involves two levels development and requirements for web applications built on three-tier architecture using Microsoft technologies. The first level estimates published by Project Managers and the second level estimates presented by Project Leaders or Developers for any new requirement or enhancements. The model considers the classification of each task as either Low or Medium or High complexity. These tasks pertain to the lowest level parts in bottom-up estimation. Efforts are estimated for designing, coding and unit testing of these tasks and the efforts are summed up to get the effort estimation for the higher level which is a feature to be implemented. The paper also discusses about the application of the effort estimation model by taking a new requirement as a case study. The first level estimates calculated using the effort estimation model has a variance of about 25% when compared with the actual effort. This variance is very much acceptable considering the fact that the first level estimates can be tolerable up to 35%. The proposed effort estimation model would help the project managers to efficiently control the project, manage the resources effectively, and improve the software development process and also trade off analyses among schedule, performance, quality and functionality. Fuzzy logic is used to verify the claims made in efforts estimation. It is proposed a new relation between the number of data and efforts value membership for actual data.

The rapid development of website-based applications that can be accessed on various computer platforms and smart phones, causing the infrastructure of web application deployment, especially servers, is needed. This causes sometimes the organization needs to invest in a server. With virtualization, companies can create multiple servers on the same machine, and each server functions as an individual machine. Lightweight based virtualization or known as containers is an approach where the host operating system is shared with a virtual server which means that the parent kernel is shared with virtual servers or containers. The method used is an experimental method, this study measures the effect of a particular treatment on a variable with different treatments. Research variables carried out in the lightweight virtualization system research, including: throughput, Average Latency, response time and Dropped Request.

User arrival rate dependent profit maximisation of web application deployment on cloud

The user arrival rate dependent profit maximisation is derived for cloud service provider (CSP) when web applications are deployed on the cloud for various instances of VM's operated using multi server queueing model. For any web application deployment on cloud, investigating the influence of user arrival rate to ensure accurate and productive usage of data to attain maximum profits is necessary. This paper is to find the profit maximisation with user arrival rate, keeping in mind the view of the dynamical changes of user requirements and attraction of the charges. The user request rate is independent of the configurable parameters like buffer size, number of VM's, and speed of the VM. To reach this objective, the finite multi-server profit queuing model is adopted and derived maximum profit through partial derivative with combination of bisection search method. Then sensitive analysis is processed and numerical illustrations are presented.

АНАЛИЗ ВАРИАНТОВ ДВУХВЕРСИОННЫХ МНОГОМОДУЛЬНЫХ ВЕБ-ПРИЛОЖЕНИЙ С ИСПОЛЬЗОВАНИЕМ ОБЛАЧНЫХ СЕРВИСОВ

The article is devoted to the analysis of a variant of two-version multi-module web application using cloud services. As the design and development of web applications are increasingly active, there is a need to increase their reliability in the face of the increasing complexity of the applications themselves and the infrastructure on which they are based. One of the key solutions to this problem is the use of cloud services, which can greatly simplify the task of ensuring the reliability and security of various applications. At the same time, cloud providers cannot fully guarantee the fault tolerance of applications that run in their environment. Therefore, users should worry about this themselves. One of the most promising approaches is the use of diversity to increase the security and reliability of web applications hosted in the clouds. The object of research and analysis of this work is a multi-module web application designed using cloud services. The study of this work aims to compare modern solutions and technologies that allow implementing sabotage for a web application. Since many companies are moving their infrastructure to the clouds, it becomes necessary to consider the possibility of using diversity by cloud services. They allow you to create and deploy web applications developed in various programming languages on the servers of cloud providers. Thus, part of the responsibility for ensuring reliability is transferred to them. However, it is still necessary to ensure the resiliency of your programs, which may fail due to defects in the program code. One of the main solutions to this problem is N-version programming, which allows you to create an application from several independent versions. Each version can be written in different programming languages and using various technologies by separate development teams, thereby increasing the reliability of the final software product. As a result, in this paper, we conclude that leading cloud providers provide the opportunity to implement diversity using services of various presentation models, such as IaaS and PaaS. Using the principle of diversity, you can design a reliable web application that will avoid its failure in case of an error in the program code.

Deployment of Web Application in LAN based 3 Tier Architecture

In the Client-Server architecture, any of web and desktop application that can be deployed with the help of 3-tier application architecture. It is consist of a presentation layer, an application layer and a data layer. All there layers does play vital role in the 3-tier architecture for performing variety of operations including business logic, storage of data and handling request. In this paper, we presented deployment process of any web application in the local area network where database and application is located on the remote or web server. Other clients only access the application via specific IP address and valid credentials. The entire request transmitted through the client application and send to the web server. Web server does provide resulted data to the requested client via the web application. We identified several loopholes from the 3-tier architecture adoption perspective and we highlighted the web application deployment interoperability issue that deserves substantial further research and development. In this paper, we investigate several tools and techniques including web server, database server and front-end tools for the successful deployment of the web application in the LAN based 3-tier architecture.
