Distributed systems, such as the Internet of Things (IoT) and cloud computing, are becoming popular. This requires modeling that reflects the natural characteristics of such systems: the locality of independent components, the autonomy of their decisions, and asynchronous communication. Automated verification of deadlocks and distributed termination supports rapid development. Existing techniques do not reflect some features of distribution. Most formalisms are synchronous and/or use some kind of global state, both of which are unrealistic. No model supports the communication duality that allows the integration of a remote procedure call and client-server paradigm into a single, uniform model. The majority of model checkers refer to total deadlocks. Usually, they do not distinguish between communication deadlocks from resource deadlocks and deadlocks from distributed termination. Some verification mechanisms check partial deadlocks at the expense of restricting the structure of the system being verified. The paper presents an original formalism for the modeling and verification of distributed systems. The Integrated Model of Distributed Systems (IMDS) defines a distributed system as two sets: states and messages, and the relationship of the “actions” between these sets. Communication duality provides projections on servers and on traveling agents, but the uniform specification of the verified system is preserved. General temporal formulas over IMDS, independent of the structure of the verified system, allow automated verification. These formulas distinguish between deadlocks and distributed termination, and between communication deadlocks and resource deadlocks. Partial deadlocks and partial termination can be checked. The Dedan tool was developed using IMDS formalism.

This article examines how Tarekat Qadiriyah wa Naqshabandiyah (TQN) utilizes online media to strengthen its existence. As an integral part of the Islamic revival in Indonesia, Sufi orders (tarekat) are facing remarkable challenges and opportunities in maintaining their existence in the digital era. Nevertheless, previous studies observed Sufi orders as a traditional community that would be exterminated by the pace of modernization and globalization. This article argues that Sufi orders may survive in the internet of things era, contrary to preceding discourses. Based on ethnography research, both online and offline, the authors found out that the vitality of the Sufi order can adapt, develop, and innovate using online media. TQN's use of online media through various platforms proves Sufi order’s adaptive efforts to the internet-based era. TQN’s online media provide informations on Islamic  and Sufism teachings, news, schedule of activities, and fundraising. Even though TQN members’ being active in cyber-Islamic environments, they resist online asceticism thus leverage the vertical-personal obedience, conservative authorities, and sacred rituals. These practices done by TQN members illuminate its identity as an authentic online sufism. Premises shown in this paper may enrich the scope of study within the relationship of Sufi orders and Islamic-cyber environment, especially in Indonesian context.

In the recent years, developments growth have been rising in utilizing of recent technologies; Smart cities have been furnished with various electronic devices concentrated on the Internet of Things (IoT) to be more smarter than before. The Internet of Things is empowered by various emerging technologies such as smart cameras, sensors, wireless communication devices etc. Smart cities are huge systems connected with countless sub-systems, and these systems are depending on the electricity to move the human, things, and data to share information. Without electric power and Internet of Things, the smart city cannot be achieved and services cannot be provided. This paper aims to provide a comprehensive concept of IoT, the smart city as well as the relationship of Smart Cities to IoT. Moreover, an extensive review of the relationship of IoT to the smart city discussed with few instances of services provided by the government using IoT technologies for the citizens. Therefore the objects and applications which come under the IoT technology that can be used to meet the objective of having a smart city. In this paper, a thorough literature on the concept of IoT with Smart City and a brief comparison of it in terms of services, challenges, and issues are discussed. Also the discussion on the issues faced by service providers with regards to technologies used to equip the citizens with up to date services.

We present a typology and process model that integrate dialectical and paradox perspectives on managing contradictions in organizations. Whereas paradox research depicts tensions between contradictory elements as irreconcilable and best managed through acceptance and synergy, the dialectical perspective portrays the relationship of such elements as adversarial and transformed through conflict. Our integrated typology and process model account for both dialectical and paradox approaches to managing contradictions and also identify two approaches, assimilation and adjustment, which combine the two. The model also identifies a key contingency, the expected distribution of power between contradictory elements, as a key influence on actors’ approaches to managing contradictions. For paradox researchers our integrated model emphasizes the need for more attention to the political, institutional, and social contexts of contradictions, practices for managing conflict, and transformation of organizational contradictions. Our integrated model suggests that dialectics researchers pay attention to the strategies managers use to productively manage tensions between contradictory elements, take a contingent view of transformation, and recognize that acceptance of contradiction may play a role in transformation. Hence our integrated model suggests a broadened agenda for both paradox and dialectics researchers.

The technological advance of the new era has led to the interconnection of devices, applications, people and data, giving way to the generation of the Internet of Things (IoT). The multiple data collected is so voluminous and variable that it must be stored in Big Data architectures. This evolution has provided the opportunity to have better access, quality and analysis of information, but at the same time, there is a challenge to prevent and mitigate the security risks associated with the relationship between IoT and Big Data, endangering the information collected and the user’ sensitive data, among others. The purpose of this document is to carry out a literature review to collect the security risks found between the relationship of Big Data and IoT, as well as evaluate the current solutions implemented and conclude if they cover the needs for prevention and mitigation of the risk.

Abstract The rapid development of technology has allowed computer simulations to become routinely used in an increasing number of fields of science. These simulations become more and more realistic, and their energetic efficiency grows due to progress in computer hardware and software. As humans merge with machines via implants, brain-computer interfaces and increased activity involving information instead of material objects, philosophical concepts and theoretical considerations on the nature of reality are beginning to concern practical, working models and testable virtual environments. This article discusses how simulation is understood and employed in computer science today, how software, hardware and the physical universe unify, how simulated realities are embedded one in another, how complicated it can get in application, practical scenarios, and the possible consequences of these situations. A number of basic properties of universes and simulations in such multiply nested structures are reviewed, and the relationship of these properties with a level of civilizational development is explored.
