The accuracy of algorithmic models for software cost prediction is limited due to their inability to handle imprecision and uncertainties associated with the software project attributes like size, programmer experience, etc. This paper enhances the accuracy and sensitivity of one of a widely used models COCOMO81 intermediate by incorporating a fuzzy component into the model. The fuzzy component...

BACKGROUND Bovine leukemia virus (BLV) is associated with enzootic bovine leukosis (EBL), which is the most common neoplastic disease of cattle. BLV infection may remain clinically silent at the aleukemic (AL) stage, cause persistent lymphocytosis (PL), or, more rarely, B cell lymphoma. BLV has been identified in B cells, CD2+ T cells, CD3+ T cells, CD4+ T cells, CD8+ T cells, γ/δ T cells, mono...

This article is devoted to the study of methods for assessing complexity development various software products. One most popular – COCOMO II was selected study. In this work, a brief description method given, and an assessment labor intensity carried out on real projects. Based results analysis, it revealed in which cases show smallest forecast error, reasons error indicators are explained. res...
