persian carpet weaving is one of iran’s most famous industries that has attracted the world’s attention to persian arts through the centuries. what above all, have given prominence to persian carpet as a beautiful work of art are the pattern and its composition in a two-dimensional space. the diversity of patterns, use of deep and beautiful colors, good composition, harmony of colors, delicate ...

Tunnel structures are known as expensive infrastructures and determining optimum designs of these structures can play a great role in minimizing their cost. The formulation of optimum design of industrial tunnel sections as an optimization is considered in this paper and then the enhanced charged system search, as a recently developed meta-heuristic approach, has been applied to solve the probl...

Censoring may occur in many industrial or biomedical ‘time to event’ experiments. Efficient designs for such experiments are needed but finding such designs can be problematic since the statistical models involved will usually be nonlinear, making the optimal choice of design parameter dependent. We provide analytical characterisations of locally Dand c-optimal designs for a large class of mode...

efficiency of enzymes which are used in industrial or environmental applications is highly dependent on their thermal stability. in this study, the stability of dfpase has been evaluated after introducing disulfide bonds to the structure. the results obtained from a series of protein design software were subjected to molecular dynamics simulation at different temperature to test the performance...

Orthogonal arrays are widely used in industrial experiments for factor screening. Suppose only a few of the factors in the experiments turn out to be important. An orthogonal array can be used not only for screening factors but also for detecting interactions among a subset of active factors. In this article, a set of optimality criteria is proposed to assess the performance of designs for fact...

This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized sa...

Using a discourse analytic qualitative approach, we investigated the naturally-occurring discourse that arose as part of two kinds of regular course activities, synchronous and asynchronous computer-mediated discussions. The messages contributed by members of a graduate course were analyzed for the kind of discourse functions and the kind of politeness strategies they displayed. Results indicat...
