Distributed Black-Box Software Testing Using Negative Selection

In the software development process, testing is one of the most human intensive steps. Many researchers try to automate test case generation to reduce the manual labor of this step. Negative selection is a famous algorithm in the field of Artificial Immune System (AIS) and many different applications has been developed using its idea. In this paper we have designed a new algorithm based on nega...

Effect of Carbon Black Content on Curing Behavior of Polysulfide Coatings

Polysulfide is well known elastomer for use in aerospace applications due to providing flexible coating and chemically resistant sealants. In this work, the effects of carbon black content on curing behavior of polysulfide elastomer were investigated and Rheological properties for samples with different filler content 15, 20 and 25 phr were evaluated by rheometric mechanical spectrometer RMS. A...

Optimization of Fermentation Time for Iranian Black Tea Production

The optimum fermentation times of black tea manufactured by two systems of Orthodox and CTC (cut, tear & curl) were investigated by measuring the quality parameters of black tea, like: theaflavin, thearubigin, highly  polymerized substances and total liquid colour during the fermentation stage. Optimum fermentation times from the beginning of fermentation were determined to be 60 min and 15...

Beyond the Black Box Approach to Ethics!; Comment on “Expanded HTA: Enhancing Fairness and Legitimacy”

In the editorial published in this journal, Daniels and colleagues argue that his and Sabin’s accountability for reasonableness (A4R) framework should be used to handle ethical issues in the health technology assessment (HTA)-process, especially concerning fairness. In contrast to this suggestion, it is argued that such an approach risks suffering from the irrrelevance or insufficiency they war...

Decolorization of Reactive Black-5 High Concentration by Vermicompost Microflora and Detoxification of By-Products by UV-C/H2O2 Post-Treatment

The presence of synthetic dyes in textile wastewater is a problematic issue for environmentalist. Nowadays, dye removal is practiced via different methods. Among all these methods, biodecolorization is an ideal technique. The present research apples vermicompost microflora to remove reactive black- C, pH = 7, and under anaerobic condition. At 36h, removal efficiencies of 94.79%, 94.06%, and 93....
