Single-arc intensity-modulated arc therapy (IMAT) has gained worldwide interest in both research and clinical implementation due to its superior plan quality and delivery efficiency. Single-arc IMAT techniques such as the Varian RapidArc deliver conformal dose distributions to the target in one single gantry rotation, resulting in a delivery time in the order of 2 min. The segments in these tec...

Quality of Service (QoS) guarantees are required by an increasing number of applications to ensure a minimal level of delity in the delivery of application data units through the network. Application-level QoS does not necessarily follow from any transport-level QoS guarantees regarding the delivery of the individual cells (e.g. ATM cells) which comprise the application's data units. The distin...

One of the main problems for rice production is the large difference between farmers' actual yields and attainable yields. Therefore, it is important to identify the limiting factors on yield and yield gap. In this research, all performed management practices from seedbed preparation to harvesting in 228 paddy fields of local rice cultivars in the east, central and west parts of Mazandaran prov...

As the cost of soybean [Glycine max (L.) Merr.] seed increases, farmers are interested in reducing seeding rates. Variable-rate (VRS) allows to adjust rates within a field by management zone, and many practice VRS soybean. However, without validation, accuracy existing practices is unknown. The objectives this study were to: (a) determine agronomic optimum rate (AOSR) predetermined zones (b) co...
