Can the height of a rice plant be measured from space? TanDEM-X, a mission designed to generate high accuracy global elevation models, has been shown to be capable of doing just that [1]. The growth of a rice plant can be observed starting from its vegetative phase, through its maturation phase until harvest. The measured height is very accurate, with a root mean square error ranging from a few...

Requirements engineering (RE) is concerned with the elicitation of the objectives to be achieved by the system envisioned, the operationalization of such objectives into specifications of services and constraints, the assignment of responsibilities for the resulting requirements to agents such as humans, devices and software, and the evolution of such requirements over time and across system fa...

most plants are able to increase soil phosphorus availability by exuding some compounds such as organic acids when they experience phosphorous deficiency. considering this special ability of plants, the main purpose of the present research was to investigate if application of organic acids may increase p availability in soil. therefore, a greenhouse experiment was conducted with five treatments...

Objective:  Presents a business goal-driven requirements engineering approach for IT to better understand system requirements, as requirements are generated from the business goals and provide assistance for analyzing business goals quickly.

Requirements Engineering (RE) contains many different practices to elicit, communicate and document customer requirements. Developers need to understand these requirements properly in order to achieve project success by fulfilling them [1]. A prerequisite for developers’ understanding of relevant requirements and their meaning is successful requirements communication [2]. Therefore, the selecte...

Bee-population declines are linked to nutritional shortages caused by land-use intensification, which reduces diversity and abundance of host-plant species. Bees require nectar and pollen floral resources that provide necessary carbohydrates, proteins, lipids, and micronutrients for survival, reproduction, and resilience to stress. However, nectar and pollen nutritional quality varies widely am...

The paper discusses the applicability of approximate NARX models of nonlinear dynamic systems to model based nonlinear control. The models might be obtained by a new version of Fourier analysis based neural network. The proposed controller is based on a discrete-time model of the plant. The objective is to incorporate plant modelling and control design into a unified framework where on the one ...
