in the present study, an attempt has been made to use data envelopment analysis (dea) for assessing the technical efficiency and return-to-scale for greenhouse cucumber production in iran. for this purpose, the data from greenhouses in esfahan province, during one period of plant cultivation in one year including spring plants were randomly collected. the results indicated that total input ener...

We propose an unsupervised method for learning multi-stage hierarchies of sparse convolutional features. While sparse coding has become an increasingly popular method for learning visual features, it is most often trained at the patch level. Applying the resulting filters convolutionally results in highly redundant codes because overlapping patches are encoded in isolation. By training convolut...

To perform tasks specified by natural language instructions, autonomous agents need to extract semantically meaningful representations of language and map it to visual elements and actions in the environment. This problem is called taskoriented language grounding. We propose an end-to-end trainable neural architecture for task-oriented language grounding in 3D environments which assumes no prio...

Improvements in robot autonomy are changing the human-robot interaction from low-level manipulation to high-level task-based collaboration. For a task-oriented collaboration, a human assigns sub-tasks to robot team members. In this paper, we consider task-oriented collaboration of humans and robots in a cordon and search problem. We focus on a path-planning framework with natural language input...

State-of-the-art TCAD software like the multi-dimensional device and circuit simulator MINIMOSNT require a huge amount of information in addition to the device input data to control several different complex modules and tasks. This information is normally hierarchically structured containing arbitrary cross-relations and dependencies that include, e.g., material properties, circuit descriptions...

State-of-the-art TCAD applications like the multidimensional device simulator MINIMOS-NT require a huge number of different information in addition to the device input data. This information is normally hierarchically structured and covers, e.g., simulation parameters, parameter dependencies, models and their parameters, material information, or circuit descriptions. Therefore, the control syst...

This paper presents and discusses a case study that applies techniques of simulation together with techniques of formal verification. A new approach in the plant modelling for formal verification of timed systems is presented. The modelling of the plant was performed by using the object-oriented language Modelica with the library for hierarchical state machines StateGraph and the simulation res...

The purpose of this research was to analyze EFL writing tasks in two of the most popular English for Speakers of Other Languages (ESOL) exam preparation courses in Iran, namely IELTS and TOEFL. Having collected the criteria of writing task appropriateness in light of the process-oriented approach to writing instruction, we asked 60 learner participants to rate EFL writing tasks in 3 IELTS and 3...
