On equationally defining extended cycle systems

ERP Systems’ Life Cycle: An Extended Version

namely the stages of decision, selection, implementation, stabilization and utilization. This last stage (utilization) is also characterized by the development of an organized effort to continuously ensure that the ERP system meets business needs regarding functionality, performance, availability, and to control operation costs, at the ERP management stage. This chapter presents aspects involve...

Guiding User Interfaces Equationally

Algebraic or equational speci cations are popular due to their simplicity. We advocate that such an approach could be of use for guiding user interfaces. If a user interface design process is to be accessible to a diverse user population that include novice computer users, it has to break out of the two stage user interface design| the rst stage, where a user interface builder is used to develo...

On diagonal cycle systems

A diagonal cycle is a cycle of length 2n together with one edge between two vertices at distance n in the cycle. For example, /{4 e is a cycle of length fonr with one extra edge between two vertices at distance two in the cycle. Methods for decomposing the complete graph Kv into diagonal cycles are given when v == 0 (mod 2n + 1) if n is odel, and when v == 1 (mod 2n + 1), if n 3 (mod 4); in the...

designing unmanned aerial vehicle based on neuro-fuzzy systems

در این پایان نامه، کنترل نرو-فازی در پرنده هدایت پذیر از دور (پهپاد) استفاده شده است ابتدا در روش پیشنهادی اول، کنترل کننده نرو-فازی توسط مجموعه اطلاعات یک کنترل کننده pid به صورت off-line آموزش دیده است و در روش دوم یک کنترل کننده نرو-فازی on-line مبتنی بر شناسایی سیستم توسط شبکه عصبی rbf پیشنهاد شده است. سپس کاربرد این کنترل کننده در پهپاد بررسی شده است و مقایسه ای ما بین کنترل کننده های معمو...
