The systems and programming staffs which have grown up within many large organizations may be described with considerable appropriateness as programming "factories." This designation could be used to characterize the programming groups employed by the computer manufacturers and those of the large companies engaged in producing proprietary programs. It is especially descriptive of the technical ...

During the 1991 and 1992 soybean growing seasons, field plots were established in South Carolina to study the effect of planting date on at-planting nematode densities and subsequent yield losses caused by Hoplolaimus columbus. The susceptible and intolerant soybean cv. Braxton was planted on five dates from to May to 28 June in 1991 and from 12 May to 28 June in 1992. Nematodes were recovered ...

A suitable planting pattern and irrigation strategy are essential for optimizing winter wheat yield and water use efficiency (WUE). The study aimed to evaluate the impact of planting pattern and irrigation frequency on grain yield and WUE of winter wheat. During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...

Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...

Introduction Radiotherapy with small fields is used widely in newly developed techniques. Additionally, dose calculation accuracy of treatment planning systems in small fields plays a crucial role in treatment outcome. In the present study, dose calculation accuracy of two commercial treatment planning systems was evaluated against Monte Carlo method. Materials and Methods Siemens Once or linea...

by studying the evolution history of budgeting systems, you may discern three stages: in the first stage, controlling role of budget is regarded its major function. in the second stage, budget is considered as a means for management improvement. in the third stage, the role of budget is considered in economic planning, implementation of programs and government performance management. after worl...

This study used panel data models with spatial error correlation to analyze private tree planting in the US South from 1955 to 2003. Controlling for statewide, fixed effects allows us to disentangle the effect of spatial interaction from that of state heterogeneity and omitted variables. The results show that there is significant spatial interdependence among the southern states in private tree...

With the advent of compositional programming models in computer science, applying planning technologies to automatically build workflows for solving large and complex problems in such a paradigm becomes not only technically appealing but also feasible approach. The application areas that will benefit from automatic composition include, among others, Web services, Grid computing and stream proce...

Planning support systems can be defined as spatial decision support systems, and they consist of three important components, namely: data, models, and geovisualisation (Klosterman 1999). In this chapter, we focus on geovisualisation in planning decision making, in which it has two roles to serve: collaboration and exploration, in particular when it is integrated with the other two components. W...

Two schools of thought exist regarding the planting of bare-root seedlings. One school favors the “pull-up” method where the seedling is pulled-up 3 to 10 cm after placing the roots in the planting hole. Although this action purportedly straightens the taproot, data are lacking to show this extra step actually improves field performance. Pulling the seedling up usually results in the root-colla...
