on time supply of materials in construction projects is very important. therefore, coordinating a project with key suppliers, while ensuring the timely supply of materials, make the minimum costs of project. one way to create this coordination is integrated inventory planning which has been accomplished in this study. it is necessary to mention that such a model is considered np_hard in terms o...

great effect of three way catalytic convertor (twc) performance on oxygen sensor output voltage has made the sensor (located after catalyst) as the main signal in almost all today’s twc monitoring algorithms. in this paper output voltage of nonlinear oxygen sensor is estimated using a nonlinear autoregressive with exogenous inputs (narx) model. the estimation uses ecu calculated exhaust gas flo...

background: the success of faculty members of medical sciences universities in medical education arena requires qualification and capabilities authentication in relation with education.  in order to achieve these capabilities, it is necessary to use new and influential approaches of empowerment. one of the appropriate approaches is “competency based training” (cbt). in this method, competencies...

We annotate individual posts following the approach in [1], [2]. Tweets are grouped by topic based on included topic hashtags. For example, tweets relating to the topic of president Barack Obama contain the hashtag #obama within them. The topic-related tweets often contain other hashtags which we assign a preliminary sentiment probability (positive and negative) using the Multinomial Naive Baye...

the direct way to access the petrophysical property of hydrocarbon reservoir is based on well data but due to its high cost, the seismic data has been used to obtain these parameters. for this purpose, many different methods are available and each has its own advantages and limitations. from these methods the seismic inversion is the best tool to study the reservoir characterization. the outcom...
