Vehicular Networks implementation has become a necessity in Smart Cities, due to the opportunistic network connectivity it offers within the city, where researches has began to focus more on Vehicular Networks, to improve the control over traffics and road safety inside the city; other researches on Smart Cities are more concerned about the transmission of the data collected by sensors, nodes, devices...
This paper presents a HV switch for the 13 series Li-ion battery cells. In order to operate at the large current of 1.0 A with the battery voltage of 46.68 V, the Differential Voltage Shaping Driver is employed to improve the slew rate of the driving voltage by 77.9%. Besides, the isolation is improved from −46.182 dB to −52.254 dB. The proposed design is implemented using a typical 0.25 um 1P3M 60V...
NASA's Unmanned Aerial System (UAS) Traffic Management (UTM) project aims at enabling near-term, safe operations of small UAS vehicles in uncontrolled airspace, i.e., Class G airspace. A far-term goal of UTM research and development is to accommodate the expected rise in small UAS traffic density throughout the National Airspace System (NAS) at low altitudes for beyond visual line-of-sight operations...
Six years have passed since the Deepwater Horizon oil spill. Work is still ongoing to assess and repair the economic and property damage caused by the accident, which was considered to be the largest accidental marine oil spill in the history of the petroleum industry. An estimated 4.9 million barrels of crude oil leaked into the sea over an 87-day period after the initial explosion.
Clean water is a natural resource that is crucial for life but has very little protection. This was exemplified by the Gold King Mine spill on August 7, 2015, in which three million gallons of acidic mine drainage was released into the head waters of the Animas River. The Animas River is the source for five water supply systems, providing drinking water for tens of thousands of people and irrigation...
While autonomy developers have been able to take advantage of external control interfaces on intelligent vehicles for years, they have typically had to choose between control architectures and interfaces that only allowed them to use the existing behaviors of the vehicle (task-level control) or those that allowed them to set desired control values (setpoint control) but then required them to re-invent...
The 2015 Gold King Mine spill exposed the Animas River (located in Durango, Colorado) to over 3 million gallons of toxic water with spiked levels of arsenic and lead among other metals. In response to public concern for the quality of the river's water, a water quality monitoring system has been developed and deployed. Multiple organizations, both local and federal, have joined forces to understand...
NASA's Unmanned Aircraft Systems Traffic Management research aims to develop policies, procedures, requirements, and other artifacts to inform the implementation of a future system that enables small drones to access the low altitude airspace. In this endeavor, NASA conducted a geographically diverse flight test in conjunction with the FAA's six unmanned aircraft systems Test Sites. A control center...
The need for a safe and economically efficient traffic represents a challenge for creating traffic management systems. This paper deals with merging three basic concepts, namely cloud-based technologies, agent-based approaches and fuzzy cognitive maps to solve the localisation and path planing for several vehicles of different types in the form of independent agents, which communicate with a supervisory...
This article studies the smoke and exhaust detection system that has been developed for monitoring exhaust gases to enforce environmental laws and regulations. In many highly populated countries the HSU (Hart ridge Smoke Unit) grade is used to impose penalties. In many cases, HSU values over 40 … 50 are leading to legal actions.
In this paper, the results of a combined numerical-experimental analysis on a system, part of a wireless sensor network, composed by a resonant electromagnetic energy harvester, a suitable power electronic interface and a sensor node are presented and discussed. Such a system is to be used onboard for real-time diagnostics and monitoring in railway vehicles for goods transportation.
One of the global main goal of the safety driving system is protecting the driver, passenger(s), car, and surrounding environment against accident which are caused by external and internal factors. Driver fatigue, one of the major internal factors, is a leading reason of vehicle breakdown according to a survey done by National Highway Traffic Safety Administration (NHTSA). Thus, it is necessary to...
Driver drowsiness monitoring is one of the most demanded technologies for active prevention of severe road accidents. Electroencephalogram (EEG) and several peripheral signals have been suggested for the drowsiness monitoring. However, each type of signal has partial limitations in terms of either convenience or accuracy. Recent emerged concept of in-ear EEG raises expectations due to reduced obtrusiveness...
This paper presents a development algorithm of hemi-cylinder projection plane applied in panorama view of AVM applications. This projection plane is established to maintain the FOV in horizontal axis. The calibration parameters are estimated with OcamCalib toolbox, and comparison of keypoint detection are showed as experimental results. Our panorama view stitching with homography matrix calculated...
Developing driving safety system with medical assistance devices for preventing accidents has become a major social issue in recent year. These devices have been developed using electrocardiogram (ECG) and photoplethysmogram (PPG) for measuring the heart rate (HR). However, driver should directly contact with the sensor for monitoring the HR. Recently, non-contact system based on continuous-wave Doppler...
Cardiovascular disease (CVD) is a considerable risk factor of driving. The pain of cardiac events distracts driver's concentration, and ischemia brought by the CVD induces incapacity of driving. In this study, a prototype of the automated safety vehicle stop system has been developed. The system collects bio-signals through the steer-sensor and recognizes the driver's posture by a camera, and detects...
Multiple objective navigation is commonly found in practice, where a path for an autonomous vehicle needs to be generated to simultaneously optimize a number of different objectives such as distance, safety, and visibility. Objectives can be weighted to solve a single objective optimization problem but appropriate weights may not be known a priori. In this paper, we formulate a series of missions...
The research aims to detect the onset of drowsiness in drivers, while the vehicle is in motion. Detection is done by continuously looking out for symptoms of drowsiness, while considering both physiological and physical signs. Physiological factors include core body temperature and pulse rate. Both of these parameters will decrease during the onset of drowsiness. These are monitored by using somatic...
Driving while feeling fatigue or drowsy may increase the chance to end up in serious accident, resulting in fatality or serious injuries. Many detection and monitoring systems have been developed for fatigue drivers but not many are focusing on sensory modalities to be used as feedback to alert the drivers. By providing multiple channels for receiving information, such a feedback could shorten the...
In this paper we have provided public Smart Assistance in Public Transport System. The project is to be implemented for public bus (for ex: PMTs in Pune).
