Modelling The Protein And Amino Acid Requirements Of The Greater Rhea (Rhea Americana), James Sales
Modelling The Protein And Amino Acid Requirements Of The Greater Rhea (Rhea Americana), James Sales
Turkish Journal of Veterinary & Animal Sciences
Protein and amino acid requirements of the Greater rhea (Rhea americana) have been estimated from growth data available for this species, and assumptions derived with other closely related species. Differences in body weight and growth pattern caused considerable higher protein and amino acid requirements for males compared to females after 3 months of age. Whereas the absolute protein requirement is comparable between males (148 g/day) and females (144.5 g/day) at 50 days of age, 21.8 g/day protein is needed by males at 500 days of age compared to 12.2 g/day for females. Limitations include the lack of knowledge on feed …

A Review Of Studies In Swarm Robotics, Levent Bayindir, Erol Şahi̇n
A Review Of Studies In Swarm Robotics, Levent Bayindir, Erol Şahi̇n
Turkish Journal of Electrical Engineering and Computer Sciences
Swarm robotics is a new approach to the coordination of large numbers of relatively simple robots. The approach takes its inspiration from the system-level functioning of social insects which demonstrate three desired characteristics for multi-robot systems: robustness, flexibility and scalability. In this paper we have presented a preliminary taxonomy for swarm robotics and classified existing studies into this taxonomy after investigating the existing surveys related to swarm robotics literature. Our parent taxonomic units are modeling, behavior design, communication, analytical studies and problems. We are classifying existing studies into these main axes. Since existing reviews do not have enough number of …

Aggregation, Foraging, And Formation Control Of Swarms With Non-Holonomic Agents Using Potential Functions And Sliding Mode Techniques, Veysel Gazi̇, Bariş Fi̇dan, Y. Si̇nan Hanay, İlter Köksal
Turkish Journal of Electrical Engineering and Computer Sciences
In this article we consider the aggregation, foraging, and formation control of swarms whose agents are moving in 2-dimensions with non-holonomic unicycle agent dynamics. We approach these problems using artificial potentials and sliding mode control. The main contribution is extension of the recent results (mainly for aggregation) in the literature based on a similar approach for simple integrator agent dynamics models to a significantly more realistic and more difficult setting with non-holonomic unicycle agent dynamics models. In particular, we design continuous-time control schemes via a constructive analysis based on artificial potential functions and sliding mode control techniques. The effectiveness of …

Aggregation In Swarm Robotic Systems: Evolution And Probabilistic Control, Onur Soysal, Erki̇n Bahçeci̇, Erol Şahi̇n
Turkish Journal of Electrical Engineering and Computer Sciences
In this study we investigate two approachees for aggregation behavior in swarm robotics systems: Evolutionary methods and probabilistic control. In first part, aggregation behavior is chosen as a case, where performance and scalability of aggregation behaviors of perceptron controllers that are evolved for a simulated swarm robotic system are systematically studied with different parameter settings. Using a cluster of computers to run simulations in parallel, four experiments are conducted varying some of the parameters. Rules of thumb are derived, which can be of guidance to the use of evolutionary methods to generate other swarm robotic behaviors as well. In the …
Swarm Robot Systems Based On The Evolution Of Personality Traits, Sidney Nascimento Givigi Jr.
Swarm Robot Systems Based On The Evolution Of Personality Traits, Sidney Nascimento Givigi Jr.
Turkish Journal of Electrical Engineering and Computer Sciences
Game theory may be very useful in modeling and analyzing swarms of robots. Using game theory in conjunction with traits of personalities, we achieve intelligent swarm robots. Traits of personality are characteristics of each robot that define the robots' behaviours. The environment is represented as a game and due to the evolution of the traits through a learning process, we show how the robots may react intelligently to changes in the environment. A proof of convergence for the proposed algorithm is offered. The process of selection of traits is discussed and the potential of the modeling is demonstrated in several …

Maternal Transfer Of Photoperiodic Information Regulates The Postnatal Reproductive System Development Of The Mongolian Gerbil (Meriones Unguiculatus), Alper Karakaş, Bülent Gündüz
Turkish Journal of Biology
We investigated whether photoperiodic information is transferred from mother to young and whether the pineal gland and its hormone, melatonin, are involved in this transfer in Mongolian gerbils. Adult female gerbils were paired with males and housed in photoperiods of 12L:12D or 8L:16D. Three groups of pregnant gerbils in each photoperiod were prepared: one group was the sham-operated control, one group consisted of pinealectomized gerbils, and one group consisted of pinealectomized gerbils that were treated with melatonin. Pinealectomy was performed before pairing the animals and melatonin injections were applied to the pinealectomized group from day 8 of gestation until parturition. …
