Development of an autonomous unmanned surface vehicle (USV) that may serve as a mother ship for a small unmanned aerial vehicle (UAV) and a small autonomous underwater vehicle (AUV), in support of surface autonomy in sensing and surveillance missions, is described. The USV development includes implementation of low-level controls, stereovision perception, and a task-oriented high-level planner, which...
Traditionally unmanned undersea vehicles (UUVs) have been large, complex and expensive. Development of UUVs has been driven by defense and commercial requirements. This has allowed for extensive research and development budgets and long development cycles. This paper briefly discuses these historic drivers and how this situation has changed. It focuses on a new compact affordable UUV. In 2015, several...
A real sea survey result of sea floor at Middle Okinawa Trough by a hovering type AUV (Autonomous Underwater Vehicle) HOBALIN is reported. The depth of the survey target area is almost the intended limit of the AUV and it was the first time for the AUV to dive down to that depth since the AUV dived first time into the real sea almost one year ago. The operation of the survey with the AUV was done...
One of the most common ways of collecting ocean data is to deploy sensors from the surface, allowing to understand the variation of water properties with depth. Autonomous vertical profilers are robotic vehicles that replace human operators in this task. They form a particular class of autonomous underwater vehicles that move predominantly along the vertical axis, typically with reduced control on...
In order to solve a series of problems about IT service management in Enterprise, such as lower efficiency and service quality, complexed business processes and communication patterns, huge static management data and dynamic control data, etc., an intelligence-awareness IT service management platform, which is based on the Cyber Physical System (CPS) for constructing smart Industry 4.0, is proposed...
Inorganic phosphor material, gadolinium oxysulphide active with terbium (Gd2O2S:Tb3+) has been previously investigated as a scintillator used in the dosimeter to detect the X-Ray dose due to its high light yield efficiency of converting the X-Ray into the visible green lights. Apart from the properties of light yield efficiency, fast scintillation and lower energy resolution matters for the clinic...
In 2015, Zheng & Carter warned that the Internet of Things (IoT) would have an exponential deployment in all types of industry in order to improve the efficiency and effectiveness of its operations. In the military sphere, it has not been different. The Ecuadorian Armed Forces are trying to equip their soldiers with IoT Technology to monitor and visualize in real time the state of health during...
Smart grid software integrates various software components in Generation, Transmission, Distribution, Smart Metering and Cloud systems. The smart grid architecture is evolving with new features and to accommodate legacy software elements. Smart grid integrated software is an evolving approach in line with modern Information and Communication technology. In this paper, the authors propose a software...
Cyber-physical agnosticism (CPA) is a property of software in cyber-physical systems (CPS) to withstand various disturbances and keep maintaining the required behaviour of the physical process. With the increased research on the use of internet of things (IoT) in industrial automation (IoT-A), there is a need for robust distributed automation control systems that can take into account some overheads...
In Internet of Things (IoT) world, there can be many sensors deployed in a system, thus their costs must be considered during the system design and material selections, in order to support massive production and deployment. Design-To-Cost (DTC) is an effective technique for this situation. In Model-Based Design (MBD), DTC cost estimates are preferred to be generated from models as one of the parameters...
Due to the advantages of cost, volume and efficiency, transformerless grid-connected power converters have drawn an increasing attention, especially in low-power PV applications. However, the lack of isolation between inverter and grid brings in some potential risks to the distribution network. Among them, the dc injection flows into the grid remains a significant concern. Owing to the offset and...
This paper proposes two non-uniform quantization schemes and also introduces an implementation system based on Software Defined Radio (SDR) consisting of GNU Radio and Universal Software defined Radio Peripheral (USRP) to sense a spectrum. In cognitive radio (CR) systems, detection and error probability are representative indicators of system performance. These performance indicators are influenced...
The paper presents a system that uses Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software to monitor, and to control the state of an electrical machine depending on user imposed limits. In this system, the real-time variables of an electrical machine are measured and transferred to a controller (PC) through Data Acquisition Card (DAQ). The NI USB 6009 DAQ is selected for this project...
This paper presents the use of a new concept: Internet of Things (IoT), applied to the fermentation process of Cocoa at the Piura's mountain range. A prototype was designed and built with sensors that record the variables of temperature, oxygen and carbon dioxide during the process and send this information to the Internet. Finally a system has been developed that receives this information, visualizes...
Software Defined Networks (SDN) has been attracting various researchers from both academia and industry to enhance the current ICT stakes and networking paradigm. The beauty of SDN is the division of Control and Data planes and make it easy for the engineers to modify the networking protocols without visiting onsite devices. Similarly, Smart Cities concept has been coined recently, where a plethora...
This paper presents the design for a prototype tactical dynamic spectrum access (DSA) mobile ad hoc network, where the network is organized into clusters operating on a single frequency. The frequency may be changed autonomously by the network in response to jamming or interference, after some frequency switching delay. The network node design is implementable on a software defined radio (SDR), such...
Combined with popular Internet of things and virtual reality technology, this paper has developed a set of intelligent agriculture, intelligent home in one of the intelligent manor sand table demo system.

Shorter innovation cycles along with the demand for individualized, high-quality products pose high challenges on today's automated material flow systems. These systems, suitable for producing bulk goods, but inflexible in case of product changes, need to react flexibly to unplanned configurations. Especially in the software domain retroactive adaptations are tedious work and prone to errors. By deploying...
