in this paper, we propose a new residual analysis method using fourier series transform into fuzzy time series model for improving the forecasting performance. this hybrid model takes advantage of the high predictable power of fuzzy time series model and fourier series transform to fit the estimated residuals into frequency spectra, select the low-frequency terms, filter out high-frequency term...

In many Mediterranean countries, users store water resources in private tanks, which are typically located on rooftops. These local reservoirs are generally connected directly to the water distribution network (WDN). This installation scheme causes a disconnection of the WDN from the users, and thus, the users’ water supply is no longer linked to their consumption, which changes the network ope...

ABSTRACT Background and aims: Identifying the costs of accidents and modeling them can encourage industries to build safety systems. Oil derivatives storage tanks are among the most important industrial facilities that are always effective in domino effects in the oil industry. Therefore, the present study investigated the economic consequences of the fire and explosion domino phenomenon in oi...

one of the water resources modeling requirements is sufficient knowledge of long-term series of meteorological and hydrological parameters. in this study the nearest neighbor resampling method presented by lall and sharma was developed. in the developed model, the knn regression was used for time series forecasting instead of local polynomial used in the developed algorithm by prairie. in this ...

This paper presents a mathematical formulation for large-scale continuous process scheduling problem using unit-specific event-based continuous-time representation. The formulation is based on the work of Ierapetritou et al., (1999). The model considers the changeovers for multi-purpose units and tanks, setup constraints for parallel units and tanks, and includes product tanks that satisfy dema...

the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...

A hoist controlled by a computer is widely used for moving electroplates which is chemically treated in a sequence of tanks. The hoist scheduling directly a.ects the throughput of a production system. The objective of the hoist scheduling problem is to schedule the moves to maximize the throughput. This paper investigates the hoist scheduling problem, a speci2c material handling issue, in a man...
