Background
Stereotactic body radiotherapy (SBRT) is gaining wider adoption for prostate cancer management but there remain significant toxicity risks when delivering prostate SBRT with standard techniques. Magnetic resonance‐guided daily adaptive SBRT (MRg‐A‐SBRT) offers technological advantages in precision of radiation dose delivery, but the toxicity profile associated with MRg‐A‐SBRT compared...

Condition monitoring systems conduct important roles in manufacturing process lines by monitoring condition status of machines to prevent accident faults of them. Those systems need to be improved in their functionalities by adapting more intellectual, self-reconfigurable, and self-decisional mechanisms for supporting smart manufacturing operations. Whereas, many enterprises in manufacturing industry...

This paper presents a novel Chained-RIpple Time Synchronization (CRIT) protocol that is scalable, flexible, and high-precise in Wireless Sensor Networks (WSN). CRIT adopts hierarchical and multi-hop time synchronization architecture with contributing energy-saving effects in WSN. The algorithm works in two phases. In the first phase, a horizontal structure between Missionary Nodes (MN) is established...

In wireless sensor networks, micro sensor nodes dispersed in real environmental field have a constraint energy capacity, so energy-efficient mechanism for wireless communication on each sensor node is so crucial. Specially, the jobs sending and processing sensing data information from on sensor node to the others are more majority parts than merely sensing some events. Thus, energy-efficient routing...

In this paper, we propose a new adaptive CSMA/CA algorithm (NACA) that aims to reduce redundant transmission of IEEE 802.15.4 LR-WPAN. In wireless sensor networks (WSN), energy consumption is one of the most important issues. Furthermore, it makes the network life-time longer by reducing retransmission. To achieve this goal, we improve the carrier sensing features in MAC layer of IEEE 802.15.4. When...

In this paper, we present a sensor network monitoring software, named NanoMon, which has a highly flexible architecture and is able to support various user requirements arising in their individual wireless sensor network applications in an adaptive manner. With NanoMon, users can specify their own sensor types and custom GUI components by using a simply describable configuration file; and it can be...

The sensor network features characteristics such as nodes being densely distributed, large quantities of nodes being scattered around, necessity of frequently changing the network topology as well as utilizing broadcasting system for communication. It also reflects a wireless network environment where batteries and computing powers are limited that it would be difficult to even make a decision on...

In recent years, the appearance of ubiquitous computing provides a fair opportunity to access diverse information and service at anyplace, anytime for users. Furthermore, those services need system architecture and context-aware and, furthermore, location-aware technologies are essential. In this paper, we suggest that a system architecture (CAS2) for handling context information based on wireless...
