In this paper, it is assumed that a robot arm with two links, works to carry out a rescue from a hole in an environment with some obstacles, and their coordinate values are known. The robot must escape to a safe domain so as not to collide with the obstacles. Virtual stakes are arranged around the neighborhood of the obstacles with complicated figures in order to facilitate the computation of distance...
We often use shortest route to reach safety place when disaster occurs, that is because it takes shorter time than others in many cases. However, it sometimes cause congestion and make evacuation time longer. In this paper we propose a method of selecting appropriate route for each evacuee according to variation of person number. We explain algorithms to select appropriate route for each evacuee and...
This paper describes a sophomore-level ECE course that bridges the gap between the maker movement and typical engineering design courses. This course incorporates the practical skills of fabrication, assembly, and hardware integration found in makerspaces but deepens the perspective from one of getting it to work to designing it to work well and efficiently. This paper discusses mastery-based education...
Learning natural disaster safety is important to equip human with awareness and preparedness if the disaster happens. Hurricane is an extreme and dangerous natural disaster which can cause loss of property and life. However, the disaster safety learning in Malaysia only covers flood, earthquake and fire. There is no safety learning to teach hurricane in Malaysia yet. Due to that, Malaysians are still...
This paper proposes an in-vehicle power line communication (PLC) system which provides an in-vehicle communication for the video and vehicle messages transmission as a reliable alternative networking medium. The proposed in-vehicle PLC system adopts an existing in-vehicle 12-V battery power system, which means we don't need an external DC power supply for in-vehicle communication equipment to achieve...
The problem of ensuring the safety of passengers waiting for public passenger transport at a halting point is considered. In addition, due to the large number of vehicles in the streets and road networks of cities, the lack of parking spaces, there is a problem of parking at bus stops. In order to solve the above problems, it is suggested to equip a bus stop with the necessary equipment for admission...
Primary goals of Advanced Driver Assistance Systems (ADAS) are increased safety and situations with no stress for all traffic participants. Parking safety is improved by presenting real-time vehicle environment to the driver (surround view, bird's eye view). Bird's eye view is 3D camera and parking sensors system which assist driver with parking. It covers all angles and alerts the driver about obstacles,...
In embedded applications, some real-time transactions may trigger external device. If these transactions fail, the influence caused by the triggered external device should be removed. The real-time database can't eliminate the influence, then we exploit compensatory task to compensate for the external influences. In this paper, the real-time transaction is divided into two parts: main task and compensatory...
This paper describes the underlying theory and ongoing development of a general-purpose collaborative system. Rooted in the critical literary theories of Barthes and Bakhtin, the dialogic web provides a potential solution to problems of collaboration in knowledge-intensive environments.
The proposed integrated system is based on the methodology and strategy of solving the problem of guaranteed safety and survivability of complex technical object (CTO) functioning, that ensures the timely decision regarding the change of object's operation mode, providing the capacity for manual correction of a set of parameters with the purpose of returning their values to a normal mode. The advantage...
The advent of wireless communication for vehicles paves the road for a bounty of cooperative applications: The most interesting being cooperative safety awareness. By exchanging information vehicles can become aware of each other and prevent dangerous situations that can lead to crashes either by early warning drivers or by automatic vehicle control, a solution particularly appealing for self-driving...
The driving system is gradually improving with the development of technology, especially for the passive safety system. However, according to the statistics of traffic accidents in Department of statistics, Ministry of Transportation and Communications R.O.C. (MOTC), there are 274,042 traffic accidents in average in the past five years. Among them, the total amount of accidents in category A1 has...
Participants sometimes cross an intersection when the red light shows but 75.5% deem this behavior incorrect. To reach the MRT station faster, pedestrians at Intersection D of Heping E. Rd. traffic circle often stepped onto the road away from pedestrian crossings, where the distance and crossing time were relatively long and the number of people crossing together was relatively large, a higher percentage...
Programmers use begin constructs in Chapel to create fire and forget-style tasks, which do not perform any implicit synchronization with the parent task. While this provides a good facility to invoke parallel tasks, it poses issues when the child task accesses a variable declared in the scope of its ancestor. If the parent task exits before the child, its scope is deallocated and the child may end...
This paper is presented to introduce a system constituting of a PLC (Programmable Logic Controller) that is connected to the level switches which is monitoring the level of the tank. This system saves the tank from over flowing which increases the safety and efficiency. The levels are considered as an input to the PLC and the pump is controlled by the output of PLC which pumps out the solvent or any...
UTE started performing LW maintenance in Transmission Overhead lines in 1989 and in Distribution in 1997 through an international call of bids. This paper refers to the Distribution experience and it includes information about LW training programs and training centers for the Distribution division.
Many guidelines for safety-critical industries, such as aeronautics, medical devices, and railway communications, specify that traceability must be used to demonstrate that a rigorous development process has been followed and to provide evidence that the developed system is safe for use. However, creating accurate and complete traceability is costly and remains a practical challenge. The significant...
The number of vehicles as well as the population of pedestrians have both increased considerably over the years. The traffic signals which are meant to regulate the traffic are often configured with only the traffic flow as the main point of design, but the number of pedestrians crossing at given a point of time is not considered, which often leads to accidents in turn causing loss of life and infrastructure...
In this demonstration proposal, we present a prototype of a rapidly deployable and cost-effective railroad crossing early warning system integrated with the railway system. Specifically, the proposed demonstration deal with the safety applications based on dedicated short range communications (DSRC) protocol and devices using our different antennas. We will demonstrate the feasibility and advantages...
Lack of network availability or limited access to communication services are among the challenges that public safety officials and first responders could face during disasters. Networking infrastructure can partially (or sometimes fully) breakdown during a catastrophe. At the same time, unusual peaks in traffic load could lead to much higher blocking probability for critical communication. A possible...
