BACKGROUND Cluster randomization design is increasingly used for the evaluation of health-care, screening or educational interventions. The intraclass correlation coefficient (ICC) defines the clustering effect and be specified during planning. The aim of this work is to study the influence of the ICC on power in cluster randomized trials. METHODS Power contour graphs were drawn to illustrate...

Background: The design of intensity modulated radiation therapy (IMRT) plans is difficult and time-consuming. The retrieval of similar IMRT plans from the IMRT plan dataset can effectively improve the quality and efficiency of IMRT plans and automate the design of IMRT planning. However, the large IMRT plans datasets will bring inefficient retrieval result. Materials and Methods: An intensity-m...

Imagining the future helps anticipate and prepare for what is coming. This has great importance to many, if not all, human endeavors. In this paper, we develop the Planning Projector system prototype, which applies plan-recognition-asplanning technique to both explain the observations derived from analyzing relevant news and social media, and project a range of possible future state trajectorie...

The work proposed a three-layer framework is proposed for mobile data collection in wireless sensor networks, which contains sensor layer, cluster head layer, and mobile collector (called SenCar) layer. The framework employ distributed load balanced clustering and dual data uploading, which is referred to as LBC-DDU. The objective is to achieve good scalability, and low data collection latency....

Although much academic research has been done on various ERP-related issues, little research has focused on the effects of business characteristics and ERP implementation strategies on the outcomes resulted from implementing ERP. Thus, the focus of this study is to explore the effects of business characteristics and ERP implementation approaches on ERP outcomes. To this end, data collected from...
