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...

The feasibility of using railroad flatcars (RRFCs) as the superstructure for bridges on lowvolume roads has been investigated in two previous research projects at Iowa State University. The results of these projects verified that RRFCs are efficient and economical alternatives for low-volume road bridges. Two county engineers involved with the RRFC project cited cost as the main factor for choo...

Abstract. A field study was undertaken to investigate the accuracy of two micrometeorological flux footprint models for calculating gas emission rate from a synthetic 10 × m surface area source, based on vertical measured at fetches 15 50 downwind source. Calculations were made with an easy-to-use tool Kormann–Meixner analytical model and more sophisticated Lagrangian stochastic dispersion mode...

Background: The position of each subject area in scientific production can indicate the ability of the scientific performance of that subject field. Since obstetrics and gynecology is one of the most important clinical sciences discipline of medical science, this study aimed to evaluate the scientific production in the field of obstetrics and gynecology before and after the Iran health reform p...

There is an increasing need to determine accurately the strength properties of tendons for an effective ground control on mines and underground structures as well as on modelling simulations. The strength properties of cables, used as cable bolts, have been evaluated mainly by their ultimate tensile strength, as this kind of test can be carried out in the field as well as in the laboratory. Onl...

Presymptomatic (PT) and prenatal testing (PNT) for Huntington’s disease (HD) have been available since 1986. Testing was initially based on genetic markers linked to the disease locus on chromosome 4p. Since 1993 and the identification of the huntingtin gene, direct analysis provides accurate PT and PNT. Recent advances in the field of molecular genetics has provided suitable tools for direct t...
