Internet of robotic things : converging sensing/actuating, hypoconnectivity, artificial intelligence and IoT Platforms
The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications
Survey of Inter-satellite Communication for Small Satellite Systems: Physical Layer to Network Layer View
Small satellite systems enable whole new class of missions for navigation,
communications, remote sensing and scientific research for both civilian and
military purposes. As individual spacecraft are limited by the size, mass and
power constraints, mass-produced small satellites in large constellations or
clusters could be useful in many science missions such as gravity mapping,
tracking of forest fires, finding water resources, etc. Constellation of
satellites provide improved spatial and temporal resolution of the target.
Small satellite constellations contribute innovative applications by replacing
a single asset with several very capable spacecraft which opens the door to new
applications. With increasing levels of autonomy, there will be a need for
remote communication networks to enable communication between spacecraft. These
space based networks will need to configure and maintain dynamic routes, manage
intermediate nodes, and reconfigure themselves to achieve mission objectives.
Hence, inter-satellite communication is a key aspect when satellites fly in
formation. In this paper, we present the various researches being conducted in
the small satellite community for implementing inter-satellite communications
based on the Open System Interconnection (OSI) model. This paper also reviews
the various design parameters applicable to the first three layers of the OSI
model, i.e., physical, data link and network layer. Based on the survey, we
also present a comprehensive list of design parameters useful for achieving
inter-satellite communications for multiple small satellite missions. Specific
topics include proposed solutions for some of the challenges faced by small
satellite systems, enabling operations using a network of small satellites, and
some examples of small satellite missions involving formation flying aspects.Comment: 51 pages, 21 Figures, 11 Tables, accepted in IEEE Communications

Modified Stage-Gate: A Conceptual Model of Virtual Product Development Process
In today s dynamic marketplace, manufacturing companies are under strong
pressure to introduce new products for long-term survival with their
competitors. Nevertheless, every company cannot cope up progressively or
immediately with the market requirements due to knowledge dynamics being
experienced in the competitive milieu. Increased competition and reduced
product life cycles put force upon companies to develop new products faster. In
response to these pressing needs, there should be some new approach compatible
in flexible circumstances. This paper presents a solution based on the popular
Stage-Gate system, which is closely linked with virtual team approach. Virtual
teams can provide a platform to advance the knowledge-base in a company and
thus to reduce time-to-market. This article introduces conceptual product
development architecture under a virtual team umbrella. The paper describes all
the major aspects of new product development (NPD), NPD process and its
relationship with virtual teams, Stage-Gate system finally presents a modified
Stage-Gate system to cope up with the changing needs. It also provides the
guidelines for the successful implementation of virtual teams in new product
development.Comment: 24 page

Research on Multi-specialty Coordination, Multi-discipline and Multifunction Integration Oriented Modeling and Simulation Innovation Technology
AbstractThe paper mainly covers the connotations, the functions and the key techniques of the Aircraft Digital Cooperative Robust Integration Optimization Performance Simulation Technology. The Performance Simulation Airplane Integration Design Platform, which has been established by the Performance Simulation Airplane construction analysis, a series of Standard Specification Establishing, the key modules development and a series of the supporting work implementation. It can be customized and be extended, and it is easy to be demonstrated. The platform contains the engineering database including the Performance Simulation Airplane model, simulation process data, simulation results data, and so on. It also provides the closed development process from the initial design to the optimized design, and end to the final detail design. It carries out the configuration selection and performance analysis for the airplane various configurations under the product development requirements in the entire process. It is applicable for the cooperative simulation analysis about the General Configuration research, the Aerodynamic design, the Structure design, the Strength design and some system specialties.
