These IoT devices chain sensing, computation, and communication techniques, which facilitates remote data collection and analysis. wireless sensor networks (WSN) connect sensing devices together on a local network, thereby eliminating wires, which generate a large number of samples, creating a big data challenge. This IoT paradigm has gained traction in recent years, yielding extensive research from an increasing variety of perspectives, including scientific reviews. These reviews cover surveys related to IoT vision, enabling technologies, applications, key features, co-word and cluster analysis, and future directions. Nevertheless, we lack an IoT scientometrics review that uses scientific databases to perform a quantitative analysis. This paper develops a scientometric review about IoT over a data set of 19,035 documents published over a period of 15 years (2002–2016) in two main scientific databases (Clarivate Web of Science and Scopus). -
Distributed Or Monolithic? a Computational Architecture
TO APPEAR IN IEEE SYSTEMS JOURNAL, DOI: 10.1109/JSYST.2016.2594290 1 Distributed or Monolithic? A Computational Architecture Decision Framework Mohsen Mosleh, Kia Dalili, and Babak Heydari Abstract—Distributed architectures have become ubiquitous in Distributed architecture is a common approach to increase many complex technical and socio-technical systems because of system flexibility and responsiveness. In a distributed architec- their role in improving uncertainty management, accommodating ture, subsystems are often physically separated and exchange multiple stakeholders, and increasing scalability and evolvability. This departure from monolithic architectures provides a system resources through standard interfaces. Advances in networking with more flexibility and robustness in response to uncertainties technology, together with increasing system flexibility require- that it may confront during its lifetime. Distributed architecture ments, has made distributed architecture a ubiquitous theme does not provide benefits only, as it can increase cost and in many complex technical systems. Examples can be seen complexity of the system and result in potential instabilities. in many engineering systems: Distributed Generation, which The mechanisms behind this trade-off, however, are analogous to those of the widely-studied transition from integrated to modular is an approach to employ numerous small-scale decentralized architectures. In this paper, we use a conceptual decision frame- technologies to produce electricity close to the end users of work that unifies modularity and distributed architecture on a power, as opposed to the use of few large-scale monolithic five-stage systems architecture spectrum. We add an extensive and centralized power plants [2]; Wireless Sensor Networks, computational layer to the framework and explain how this can in which spatially distributed autonomous sensors collect data enhance decision making about the level of modularity of the architecture. -

These spacecraft are not responsive to failures or changes in mission requirements, as both require the launch of a completely new spacecraft. The concept of fractionated spacecraft was introduced in 2006 by the US Defence Advanced Research Projects Agency (DARPA) as a way of designing and operating space systems which is more responsive than current methods. -

HIP Brief History of the Internet of Things and the Elusive Quest to Measure Performance
HIP Brief History of the Internet of Things and the Elusive Quest to Measure Performance Shoumen Palit Austin Datta MIT Auto-ID Labs, Department of Mechanical Engineering, Massachusetts Institute of Technology, Cambridge, MA MDPnP Lab, Department of Anesthesiology, Massachusetts General Hospital, Harvard Medical School, Cambridge, MA Center for Robots & Sensors in Human Well Being, School of Engineering Technology, Purdue University, W. Lafayette, IN ABSTRACT Performance is a purveyor for the progress of civilization. Progress is synonymous with improvement, efficiency and a general sense of being or building better than before. Quantification of states before and after are indicators of the value of performance, which, if positive, may constitute tangible (physical, procedural) or intangible (moral sentiments, security) contribution toward progress. Social and scientific tools to measure performance are a part of our historical progress. In the past few centuries frameworks and tools have been developed. In the 20th century electrification, automobiles, computation and connectivity accelerated our pace of progress. In the 21st century even more tools and technologies are attempting to measure many different aspects of performance. This brief essay is an attempt to selectively discuss a few of these concepts and how they relate to performance measurements. Here we consider the underlying concept of connectivity and how it has germinated the ideas we refer to as the internet of things (IoT), context awareness and the interaction between percepts, environment, actuators and sensors (PEAS). The complexity of these related domains and their convergence shapes performance. Measurement of isolated parts may offer an incomplete glimpse of performance but that is all which is possible, at present. -

Rocha Submitted to the Program in Media Arts and Sciences, School of Architecture and Planning, on August 5, 2005, in partial fulfillment of the requirements for the degree of Master of Science in Media Arts and Sciences Abstract This thesis proposes a network architecture, called SMPL, for the design and development of collaboration-oriented, distributed applications over the Internet. The goal of SMPL is to enable the development of applications that easily integrate the capabilities of different types of computing resources, software platforms, and data repositories across the Internet transcending the level of a single device. SMPL proposes a new abstraction of the Internet as a network composed of services, resources, and capabilities instead of just machines. -

Proceedings of the 2nd International Conference On Systems Engineering and Modeling (ICSEM-13) Hybrid Approach to Optimize the Cluster Flying Orbit for Fractionated Spacecraft Based on PSO-SQP Algorithm Shenghui Wan1, a, Junling Song 2,b, Jian Chen 1,c , Min Hu2,b 1China Satellite Maritime TTC Department, Jiangyin, China 2Academy of Equipment, Beijing, China [email protected], [email protected], [email protected] Keywords: Fractionated spacecraft; Cluster flying orbit; Relative orbital elements; Particle swarm optimization; Sequential quadratic programming. Abstract. This template This paper investigates the optimal cluster flight orbit design issue for the fractionated spacecraft according to three main goals: keeping the cluster as stable as possible, preventing the collisions within the cluster, maintaining the inter-satellite distance within the maximum region. Firstly, the relative orbital elements are adopted to describe the relative motion. Then, the formation design requirements are formulated in terms of the relative orbital elements, the constrained optimization problem is solved using the hybrid particle swarm optimization algorithm integrated with sequential quadratic programming local search. The simulation results show that the hybrid PSO-SQP algorithm is effective. Introduction Fractionated spacecraft has been well concerned in recent five years because of its unique technical merits. The concept of the fractionated spacecraft is to separate the traditional monolithic satellite into free-flying service modules and different payloads, which are connected by self-organizing network wirelessly. DARPA began a program called the System F6 (Future, Fast, Flexible, Fractionated, Free-Flying Spacecraft) in 2008. The fractionated spacecraft usually consist of tens and scores of modules and the modules often operate in close proximity, which make the cluster flying orbit design issue more challenging [1]. -

Untuk keluarga penulis yang selalu memberikan masukan serta saran kepada penulis. Untuk kemajuan teknologi dan keilmuan di Indonesia. iv v vi ABSTRAK Angka konsumsi LPG untuk rumah tangga di Indonesia terus meningkat setiap tahunnya. Pemerintah Indonesia sendiri pernah mensosialisasikan program konversi minyak tanah ke gas LPG pada tahun 2007. Hal inilah yang mendasari maraknya penggunaan LPG untuk rumah tangga. Namun, ketergantungan terhadap LPG ini masih menimbulkan adanya masalah. LPG yang digunakan untuk kebutuhan rumah tangga sering kali mengalami kebocoran. Kebocoran gas tersebut sering mengakibatkan kebakaran dalam rumah, sehingga banyak masyarakat yang masih khawatir dalam penggunaan LPG. Berdasarkan latar belakang inilah penulis membuat rancang bangun kendali gas untuk mencegah kebakaran akibat kebocoran LPG menggunakan Fuzzy Logic berbasis Internet of Things.
