Learning from experience in positioning new computer products

The correct positioning of new computer products has become crucially important as markets saturate and competition intensifies. The logistic function can provide an aid to product positioning. The method presented her addresses questions of price and performance only, and involves determination of learning curves from data on past successful product launches. It assumes that companies learn like individuals and that variables such as performance/price grow according to logistic curves limited by the basic technologies at hand.Digital's experience shows that its VAX family of computers is amenable to such an analysis, which also provides insights on the overall evolution of that technology. Besides offering guidelines for product positioning, this approach provides a means for estimating price drops and/or performance enhancements necessitated from delays in product delivery.

Studying the Big Data Paradigm in Dynamics of Its Advance

The study of the big data subject matter in its advance already has its own history. Assuming as a basis the content analysis of article abstracts on big data, using e-library stocks of Association for Computing Machinery (ACM) and Institute of Electrical and Electronics Engineers (IEEE), one succeeds to monitor the life cycle phases of the big data paradigm and distinguish the stages of developing programs and algorithms from the technology update, including applications and their advanced renewals. In order to carry out the analysis, it is proposed to approximate the curves of cumulative frequencies of words, obtained from the corpus of texts by means of cubic parabolas, their parameters being in good concordance with ones of logistic curves.

Size at first maturity and maturity stages of Terapon jarbua (Forsskal, 1775) from Pondicherry Coast, India

Size at first maturity of Terapon jarbua was studied based on 114 male (14 to 28 cm in TL) and 140 female (14 to 32 cm in TL). The Logistic curves describing the relationship between the sexes and the proportion of 50% maturity (Lm50) were estimated at 20.8 cm in male and 21.8 cm in female of Terapon jarbua. The male reached 50% first sexual maturity at smaller lengths than female in this species. The gonads were classified into five maturity stages based on the size, colour and texture. Month wise predominance of different stage of maturity deferred during different months.
