A known characteristic of the Tropical Pacific is the interaction between the zonal winds and the equatorial thermocline, which allows coupled variability like ENSO to evolve. However, this fundamental feedback is the least understood and most poorly modeled element of the tropical climate system. To increase our knowledge of the mechanisms controlling this feedback process, NOAA's National Data Buoy...
Design by contract and relational interface theories are powerful for specifying component-based systems. We extend these theories with real-time properties so that our technique can model component-based real-time systems. In addition, we use linear temporal logic (LTL) for specifying the invariant properties of contracts. To specify the interaction between methods in a component, and the interaction...
A real-time remote data acquisition and process monitor system based on ARM and Ethernet is designed for automatic filling line. The whole scheme of the system is analyzed and the hardware and software design of the system is discussed in details. Though obtaining intuitive image video information and analyzing the real-time display data or history date which come from the production line, people...
We demonstrate a low-power CMOS ISFET array for pH sensing which is inductively powered using NFC. Each pixel in a 3-by-3 array contains an ISFET operating in weak-inversion which detects changes in pH as a current. The output of all pixels is then averaged and converted to a frequency using a current-starved ring oscillator. We make use of a commercial NFC IC, the SIC4310, to harvest power from a...
This article presents a real-time control system for an experimental model of a water distribution system. The hardware and software implementation follows the latest trends in IoT and proves that such an architecture can be used for real-time process control in distributed systems. The control of flow is implemented using a multiple-model control algorithm for the pumping station. A method which...
Precision agriculture relies on real-time data gathering and analysis to maximize yield, minimize environmental impact and reduce cost, which has been envisioned as a new paradigm to revolutionize modern agriculture. However, the collection of farming data, especially geospatial data, raises concerns about potential privacy leakage. In this paper, we propose a novel scalable and private continual...
Real-time DataBase Management Systems (RTDBMS) have been considered as a promising means to manage data for data-centric automotive systems. During the design of an RTDBMS, one must carefully trade off data consistency and timeliness, in order to achieve an acceptable level of both properties. Previously, we have proposed a design process called DAGGERS to facilitate a systematic customization of...
In this paper we propose event goodput, i.e., the fraction of events which may be successfully managed by a system, as a relevant metric to describe the performance of battery powered real-time sensor networks. Unlike other performance metrics as response, completion, maximum lateness times, all representing fundamental, but different, figures of merit for the description of the behavior of real-time...
Water is one of the precious factors in human life. It plays a vital role in the survival and existence of flora and fauna. But, now a days it is been exploited heavily by dumping of human waste, industrial and chemical waste in to the water bodies which is the resultant of water being contaminated with toxic chemicals. Water scarcity and water contamination has been one of the major issues faced...
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...
During recent years, we have witnessed an explosion in the Internet of Thing (IoT) in terms of the number and types of physical devices. However, there are many limitations of these devices regarding their computing power, storage, and connection capabilities. They affect on-device processing of sensed data significantly. Centralized treatment of IoT data has proven challenging for many use cases...
Automation of modern industrial plants require real-time tracking of object locations and sensing of local and ambient parameters for variety of applications such as counting and tracking of objects in assembly line, detection and positioning of failures of machines etc. Mostly, discrete Real Time Location System (RTLS) performs object tracking in existing industrial automation without its integration...
The use of big data for cyber-physical systems (CPS) is gaining more importance due to the ever-increasing amount of collectable data. Due to the decreasing cost of sensors and the growth of embedded systems, which are increasingly used in the industries as well as in the private sectors, new methods are needed to evaluate and process the collected data. Therefore, in this paper we proposed a framework...
The total US box office revenue exceeds ten billion dollars a year. Inevitably, new product forecasting and diagnosis have high financially stakes. The motion picture industry has a huge incentive to perform early prediction of movie success or failure. In this paper, we present a study that evaluate viewer responses to short movie trailers using a cap instrumented with Electroencephalogram (EEG)...
Aiming at the rapid scheduling of collaborative detection traffic in Internet of things (IOT), a cooperative detection scheduling model about the bottom of IOT was designed in the paper; the model prioritized the traffic data of the sensing layer through the local scheduler of the collaboration layer, then an improved weighted round robin (IWRR) method was used to schedule the traffic data, the IWRR...
To address the tip positioning problem among flexible link robotic applications, we propose a new circular beam deformation model that is ideally suited for networked linear accelerometers and rate gyros. Importantly, the tip positioning problem of multiple-flexible-link system is reduced to the tip positioning problem of an individual flexible link subject to the circularly characterized deformation...
Heavy vehicle traffic and flooded areas are problems experienced on roads because of unimproved road infrastructures and environmental deviations. These factors affect vehicle drivers negatively as they contribute to stress, health problems, and wastefulness of time. This study developed a system called ArRoad that monitors and analyzes vehicle traffic and flooded areas using network of sensors and...
Smart environments based on Internet of Things (IoT) are very active area of research. Another task highly relevant in today's world is emergency management and situation awareness support systems.
