An Improved Algorithmic Method for Software Development Effort Estimation
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. ...
متن کاملAn improved fuzzy forecasting method for seasonal time series
Several time-variant fuzzy time series models have been developed during the last decade. These models usually focus on forecasting stationary of trend time series, but they are not suitable for forecasting seasonal time series. Furthermore, several factors that affect the forecasting accuracy are not carefully examined, such as interval length, interval number, and level of window base. Aiming...
متن کاملAn improved HPLC method for determination of colocynthin in colocynth
Background and objectives: Colocynthin is the major active secondary metabolite of colocynth, Citrullus colocynthis (L.) Schrad, which has been used in traditional and ethno medicine of many countries. It could be considered as an active marker for quality control of colocynth and its herbal products. Analysis and standardization of colocynth and its herbal preparations are a critical...

متن کاملImproved Holt Method for Irregular Time Series
The paper suggests an improvement of Holt method for irregular time series as was presented by Wright. The modification deals with problem of time-close observations, i.e. two subsequent observations with time distance much shorter than in average. If this situation occurs in time series when using the original Wright’s formulae, one can obtain seriously wrong results. Simulation study is provi...
