speed in electronic transactions forms a new kind of software agreements known as end use license agreement. in american legal system, there is no unit procedure. end user license agreement was begun by shrinkwrap and clickwrap agreements. browsewrap agreement is the latest development type of them. shrinkwrap agreements are usually formed by opening of the plastic cover of software package or ...

maintenance is one of the inseparable parts of each industry and relations between this part and others consist of many dynamics and feedbacks. by this regard systems dynamic is a tool that can be used to analyze this part. in this paper for a company that produces wire and cable, cause and effect (feedbacks) between maintenance and others part are modeled. after creating stock-flow diagram, mo...

drug design is generally achieved through trial and error methods, which is a time and resource consuming process and novel methods are needed to improve it. mathematical modelling is one of the possible solutions to speed up this process. in this study, we have presented box-jenkins model, to predict the vasorelaxant activity (pec50) of a set of benzopyrane compounds. we used the hyperchem sof...

T need to validate large amounts of data with the help of the domain expert arises naturally in many dataintensive applications, including data mining, data stream, and database-related applications. This paper presents a general validation approach that generalizes different expert-driven validation methods developed for specialized validation problems. In particular, we model the validation p...

Model validation in model-driven development gains in importance as the systems grow in size and complexity. In this situation an efficiency of validation execution and an immediate feedback whether a recent manual edit operation broke a validation rule is desirable. To increase efficiency, incremental model validation tries to minimize the proportions of the model that have to be rechecked by ...

Background & Aims: Fatigue Severity Scale (FSS), due to its simple and clinical nature, is frequently used to measure fatigue level in patients. Since fatigue is a common symptom in multiple sclerosis (MS) disorder, the present study aimed at evaluating the psychometric properties of the Persian version of FSS in patients with MS. Methods: This study was descriptive and of a validation type, in...

The method has been developed and validated for the determination of hydroquinone in liposomal formulation. The samples were dissolved in methanol and evaluated in 293 nm. The validation parameters such as linearity, accuracy, precision, specificity, limit of detection (LOD) and limit of quantitation (LOQ) were determined. The calibration curve was linear in 1-50 µg /mL range of hydroquinone an...

The present study was an attempt to refine a qualitatively proposed model of ELT discipline-specific reading strategies to provide a better interpretation of qualitative findings. Hence, in line with the components of the previous model, that is, 6 factors and 32 categories, a 6-hypothetical factor and a 33-item questionnaire were considered in the design of the ELT discipline-specific question...

The use of L1 in language classroom has been traditionally repressed by applied linguists. However, in recent years, it is believed that switching to L1 can be considered a pedagogical instrument by teachers rather than a heterodox. Consequently, this two-phase study was an attempt to investigate the functions that are fulfilled by EFL teachers through their use of L1. In the first phase (i.e.,...

One of the difficulties of using model checkers “in the large” is the management of all (generated) data during the validation trajectory. It is important that the results obtained from the validation are always reproducible. Without tool support, the quality of the validation process depends on the accuracy of the persons who conduct the validation. This paper discusses Xspin/Project, an exten...
