In this paper, coefficient sensitivity of polynomialpredictive FIR differentiators (PPFD) is investigated for implementations in fixed point environments, and advantageous guidelines for creating robust designs are given. By joint selection of an appropriate filter length and implementation structure, sufficient prediction and differentiation properties can be maintained even in short word-leng...

this paper presents an economic evaluation of gas to liquids (gtl) project using “south-pars” gas field of iran based on the latest actual performing gtl projects. iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of gtl products which have lower pollution and higher quality than refinery products. the results of cost-benefit analysis sho...

Accurate measurement of the stain variation and effective distinguishment temperature-induced stress from load-induced have been major objectives for strain sensors in crane monitoring. In this paper, a fiber Bragg grating (FBG) sensor with low temperature-sensitivity, packaged by two gripper tubes stainless-steel tubes, is presented applied bridge health monitoring project. Calibration experim...

the acceptance of the right project which leads to the realization of the set objectives is one of the most important issues in project-oriented companies. therefore, corporate managers prefer to work on those projects which ensures the achievement of goals such as increasing financial profits or being the top brands in their rivals market. the present  research aimed at introducing  a systemat...

Project portfolio selection is very important subject of decision-makers in project-based organizations. The best assignment of resources to the most appropriate projects is necessary as financing projects with low benefit is just waste of organization's resources. However, existing project selection models pay not much attention the structure and special features of projects as a selection cri...

Sensitivity to environmental concepts is closely related naturalistic intelligence, as well concern for finding solutions problems through problem-solving skills. This study aimed determine the correlation between intelligence and ability photovoice project. Correlational research method was used in this with purposive sampling technique. Population were 10 th grade students of senior high scho...

Digital computing devices have a finite precision. Hence when digital controllers are implemented, there is rounding on the variables and parameters resulting in the various finite-word-length effects on the closed-loop stability and performance of the system. In this paper we concentrate on the coefficient sensitivity problem. That is: to determine the controller realization that minimizes the...

Accurate estimating is one of the most important activities in the field of software project management. Different aspects of software projects must be estimated among which time and effort are of significant importance to efficient project planning. Due to complexity of software projects and lack of information at the early stages of project, reliable effort estimation is a challenging issue. ...
