Abstract

Self-adaptivity is mainly used to address uncertainties, unpredicted events, as well as to automate administration tasks. It allows systems to change themselves while executing in order to address expected or unexpected changes and to adapt as much as possible to the current execution context. Self-adaptivity is particularly meaningful for dynamic application domains such as Internet of Things (IoT), Cyber-Physical Systems (CPS), service oriented based solutions (SOA), cloud computing, robotics, among many others. There are various available solutions in these domains that exploit self-adaptivity. The question is how can we analyze them to understand how self-adaptivity is implemented and exploited in order to use and re-use, as well as to adapt existing solutions to new or other systems? In this paper, we propose a first step in this direction, by analyzing available self-adaptive systems (and especially their self-adaptive mechanisms) in various application domains using the Understand tool - widely used for software development, analysis, and quality assessment.

Abstract

The purpose of this study was to determine the effect of the capital adequacy ratio on return on capital in the Islamic banking sector and in conventional banks within five years of observation (2018-2022). The population used in this study consisted of 6 banking companies. The sampling technique is a purposive sampling technique. Based on the results of multiple linear regression analysis, it can be concluded that the effect of CAR on ROA in Islamic banks and conventional banks states that the CAR value based on statistical tests has a positive and significant effect on ROA

Abstract

Online software services are often designed as multi-tenant, API-based, microservice architectures. However, sharing service instances and storing sensitive data in a shared data store causes significant security risks. Application-level access control plays a key role in mitigating this risk by preventing unauthorized access to the application and data. Moreover, a microservice architecture introduces new challenges for access control on online services, as both the application logic and data are highly distributed. First, unauthorized requests should be denied as soon as possible, preferably at the facade API. Second, sensitive data should stay in the context of its microservice during policy evaluation. Third, the set of policies enforced on a single application request should be consistent for the entire distributed control flow.
