An agent based evacuation model with car-following parameters for micro traffic by means of cellular automata is proposed. The model features smart drivers who have a concern the distance between the driver and the surrounding cars. Such drivers are called agents. Agents lead the other cars not only in an ordinary case but also in the case of evacuations. We put the smart drivers and the agent drivers into the car-following parameters of traffic model. We applied it in the case of evacuation. Experimental simulation results show the effectiveness of reducing the evacuation time by the agents. It also is found the effectiveness increases in accordance with increasing of the number of agents. © 2010 Springer-Verlag Berlin Heidelberg. Source

The E-health sensor is one of the technologies of the wireless body area network (WBAN), which has a wide range of sensors that can be used to check a person's health data. In this work, we implement an E-health sensor system that can be used to read health vital sign data and store it in a database server. The sensors used in this work are a body temperature sensor and a blood oxygen sensor. The method that we used enables us to show the results of the sensor readings to a desktop application, then read the printout of the series and create a visual in the form of tables and graphs, as well as store the data in a database and display the data via a website in the form of reports that can be accessed remotely. After doing some testing on the user, it can be concluded that this application can be used to access health data remotely. © 2015 MYU K.K. Source

The personal area network (PAN) coordinator can assign a guaranteed time slot (GTS) to allocate a particular duration for requested devices in IEEE 802.15.4 beacon-enabled mode. The main challenge in the GTS mechanism is how to let the PAN coordinator allocate time slot duration for the devices which request a GTS. If the allocated devices use the GTS partially or the traffic pattern is not suitable, wasted bandwidth will increase, which degrades the performance of the network. In order to overcome the abovementioned problem, this paper proposes the Partitioned GTS Allocation Scheme (PEGAS) for IEEE 802.15.4 networks. PEGAS aims to decide the precise moment for the starting time, the end, and the length of the GTS allocation for requested devices taking into account the values of the superframe order, superframe duration, data packet length, and arrival data packet rate. Our simulation results showed that the proposed mechanism outperforms the IEEE 802.15.4 standard in terms of the total number of transmitted packets, throughput, energy efficiency, latency, bandwidth utilization, and contention access period (CAP) length ratio. © 2015 Published by ITB Journal Publisher.

In IEEE 802.15.4 beacon-enabled mode, the personal area network (PAN) coordinator can assign guaranteed time slot (GTS) to allocate a particular duration for requested devices. The main challenge in GTS mechanism is how the PAN coordinator allocates time slot duration for the devices which request GTS. However, if the allocated devices use GTS slot partially or the traffic pattern is not suitable, the wasted bandwidth will increase which make degrade the performance of network. In order to overcome the above mentioned problem, this paper proposes a partitioned GTS allocation scheme (PEGAS) for IEEE 802.15.4 networks. PEGAS aims to decide the precise time for the starting time (GTSstart), the end of GTS (GTSend), and the GTS length (GTSlength) allocation for requested devices taking into the value of superframe order (SO), length of data packet and arrival data packet rate. The simulation results show that the proposed mechanisms outperform the IEEE 802.15.4 standard in terms of total of transmitted packet, throughput, energy efficiency, and latency. © 2013 IEEE.

Instability is one of the major defects in humanoid robots. Recently, various methods on the stability and reliability of humanoid robots have been studied actively. We propose a new fuzzy-logic control scheme for vision systems that would enable a robot to search for and to kick a ball towards an opponent goal. In this paper, a stabilization algorithm is proposed using the balance condition of the robot, which is measured using accelerometer sensors during standing and walking and turning movement are estimated from these data. From this information the robot selects the appropriate motion pattern effectively. In order to generate the appropriate reaction in various body of robot situations, a fuzzy algorithm is applied in finding the appropriate angle of the joint from the vision system. The performance of the proposed algorithm is verified by searching for a ball, walking, turning tap and ball kicking movement experiments using an 18-DOF humanoid robot, called EFuRIO. Source
