The concept of city information modeling (CIM) has become increasingly popular in recent years. A literature review of previous CIM studies is presented in this paper. First, a bibliometric analysis of the current global CIM research is described, revealing that CIM has become a significant research hotspot. Next, three main research areas of the current CIM technique, namely data collection, integration, and visualization, are summarized to describe the characteristics of CIM research. Furthermore, some widely used CIM platforms are compared, and typical application cases of the CIM technique at different stages of the city life cycle are summarized. Finally, the current issues in CIM research are discussed, and future development directions are proposed. The findings of this study are expected to help researchers understand the current state of CIM and identify future development directions, thereby promoting CIM research development.

Bibliometric Review

Recently, architecture engineering and construction (AEC) industry benefits from building information modeling (BIM) as a technology-based development, to enhance collaboration and increase the efficiency of construction projects. After implementing BIM in design and construction phases, developed countries now head towards utilization of BIM in facilities management (FM) processes. As ranking among the leading AEC industries, Turkey not only follows latest developments but also promises valuable potentials for both theoretical and practical improvement of BIM. Based on the studies published in BIM field, this study applies bibliometric review approach to analyze the state-of-the-art situation of the field in Turkey, and determine potential research areas, especially in BIM and FM intersection. Following the systematic literature search that aims to introduce current efforts of Turkish researchers in BIM field, the qualitative analysis categorizes these efforts according to life cycle phases of a construction project and provides a vision on existing knowledge as well as research gaps. Findings of this study point out the important contributions of Turkey to BIM field especially in design and/or construction phases. A prominent conclusion of this study also signals a need for more FM oriented approach in BIM researches.

Visual simultaneous localization and mapping (SLAM) is well-known to be one of the research areas in robotics. There are many challenges in traditional point feature-based approaches, such as insufficient point features, motion jitter, and low localization accuracy in low-texture scenes, which reduce the performance of the algorithms. In this article, we propose an RGB-D SLAM system to handle these situations, which is named Point-Line Fusion (PLF)-SLAM. We utilize both points and line segments throughout the process of our work. Specifically, we present a new line segment extraction method to solve the overlap or branch problem of the line segments, and then a more rigorous screening mechanism is proposed in the line matching section. Instead of minimizing the reprojection error of points, we introduce the reprojection error based on points and lines to get a more accurate tracking pose. In addition, we come up with a solution to handle the jitter frame, which greatly improves tracking success rate and availability of the system. We thoroughly evaluate our system on the Technische Universität München (TUM) RGB-D benchmark and compare it with ORB-SLAM2, presumably the current state-of-the-art solution. The experiments show that our system has better accuracy and robustness compared to the ORB-SLAM2.

Computing Environments

The explosive emergence of distributed computing environments and component-based architectures increases the demand for flexible information modeling paradigms. A review of the state-of-the-art shows that contemporary modeling methods and technology, such as object-orientation (OO) and CORBA, facilitate to an extent the functional integration of heterogeneous information management systems. However, there are still issues to be resolved that mainly involve (i) the inflexibility of modeling semantics adopted by OO methods, (ii) the complication of developing new service components and their deployment in a distributed management environment. This chapter attempts to pinpoint some of those difficulties and suggests ways to overcome them. In this direction, we give a short overview of the problems encountered in the current state-of-the-art that act as motivation for this research. In response to challenges identified, we then continue on two main strands of analysis, one theoretical and one practical. In the theoretical part we introduce the Model of Object Primitives. It aims at providing a more flexible way to model information. The main objective here is to simply pinpoint the basic principles and elements of the model and not provide a thorough analysis of its semantics. The semantics of the model is analytically described in (Georgalas, 2000). Finally, in the practical part we present an information management architecture that adopts the idea of primitives in order to build components and deliver information services to client applications.

Over recent years, telehealth has increasingly demonstrated its value in supporting the delivery of cardiovascular healthcare. From teletriage services as a portal into healthcare through to telemonitoring of heart failure patients, technology is already increasing the ability of practitioners to provide care remotely, empower patients and improve clinical outcomes. In the future, telehealth services have the potential to have an even greater impact on the provision of cardiovascular care. Embedding telehealth services into mainstream cardiac care, the development of more sophisticated devices and the utilisation of technology in a wider range of clinical contexts will help to accelerate the adoption of telehealth throughout healthcare. This article evaluates the current state of the art in telehealth provision and explores some of the areas for future development in this fast-moving and exciting area of clinical practice.

Software Defined Networking (SDN) is an evolving network architecture paradigm that focuses on the separation of control and data planes. SDN receives increasing attention both from academia and industry, across a multitude of application domains. In this article, we examine the current state of obtained knowledge on military SDN by conducting a systematic literature review (SLR). Through this work, we seek to evaluate the current state of the art in terms of research tracks, publications, methods, trends, and most active research areas. Accordingly, we utilize these findings for consolidating the areas of past and current research on the examined application domain, and propose directions for future research.

Due to the complexity, associated cost, and general uncertainty of performing the creative design process, significant value exists in reusing the design information developed in previous design efforts. This paper outlines the current state of the art in design reuse in various fields as well as identifying both the current and future research areas. In addition, this paper describes the link between adaptable design and design reuse. Finally, as the first step in our research, this paper describes the direction that the research will take: an analysis of the use of adaptable design to enhance the design reuse process.

Private companies play a significant role and are the main growth engine of the global economy. Yet, until recently, empirical research in accounting has focused primarily on public companies. Over the last few years, we have observed a change in trend. Accounting scholars have started researching private firms and have contributed to a better understanding of their accounting decisions. This growing attention is likely due to a better availability of public data and to the fact that several regulators issued specific regulations on private firms’ financial reporting. In this paper, we analyze the state of the art of accounting research in this area. We review 95 papers published in 21 accounting journals over the period 1986–2018. After looking into the definition of private firms, we highlight the role of the private firm status in the research design, classify each paper into four main research areas (i.e., financial accounting, taxation, auditing, and valuation) and discuss the main contributions. We argue that the current state of accounting research on private firms — although quite rich — is still insufficient in light of the relevance of such a segment of the world economy. After soliciting additional research, we devise possible venues for future studies.
