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...
Mating Systems and Strategies
applicability. There is not enough discussion about possible empirical approaches to the niche concept (Chapter 4). Although this is probably due to niche hypotheses being very difficult to test empirically, it will be necessary if their framework is to be adopted at all. The authors boldly claim that the niche framework is able to provide explanatory hypotheses about macroecological and macro-...
متن کاملMale mating behaviour and mating systems of bees: an overview1
Considerable interspecific diversity exists among bees in the rendezvous sites where males search for females and in the behaviours employed by males in their efforts to secure matings. I present an evolutionary framework in which to interpret this variation, and highlight the importance for the framework of (i) the distribution of receptive (typically immediate post-emergence) females, which o...
متن کاملAssortative mating based on phenotype. I. Two alleles with dominance.
I N animals with separate sexes several traits are known to induce some sort of preference for mating between similar individuals (assortment) or preference for mating between dissimilar individuals (disassortment) . Assorting, for example, is known to occur in certain bird, mammal (man included) and insect populations. Traits affecting preferences can be partly subject to environmental control...
