An attempt has been made to explain the features of the wrist structure of crocodiles, which sharply distinguish them from other reptiles. Biomechanical model of a crocodilian forearm and manus is created with using of the vector contours method from the theory of mechanisms and machines. The key role of the V finger in the manus stability during the stance phase is shown. On the basis of this data, it is concluded that there is no bipedal stage in evolutionary history of crocodiles and their high specialization for quadrupedal parasagittal running with the emergence of a gallop as a result. The special way of parasagittal forelimb posture of the crocodiles offered to name instant parasagittality.

This paper presents the developed algorithms for a tool environment for the design of complex information systems based on automata models using the algebra of high-dimensional vectors. The paper raises the problem of the little knowledge of methods of coding complex systems in the format of automata based on the algebra of hyperdimensional vectors. Methods of formalized description of systems in the form of hyperdimensional vectors and description of algorithms for transformation of formalized description using the algebra of hyperdimensional vectors are introduced. The features, advantages and disadvantages of modeling automata models using hyperdimensional vectors are listed.

This article is devoted to a method for converting a temporary machine into a script for load testing of a messaging service. The concept of operation of temporary finite state machines, unconditional and conditional transitions with a time delay in them is considered. The existing solutions of the program for load testing were analyzed, their advantages and disadvantages were identified. A method of developing a script for a load testing tool "Gatling" using temporary state machines specified by the user is presented. A method for organizing an unconditional and conditional transition with a time delay is proposed to emulate the work of real users with the system, for load testing. The solution is the ability to synthesize a finite state machine that will be transformed into a script in the "Scala" language.

We describe the crocodile forelimb features that distinguish them from other reptiles. Reduction of the clavicle and a change in the coracoid shape seem to be another way of maintaining the efficient step length, while the antebrachium and manus transformations create peculiar oblique manus position on the ground to promote the forelimb parasagittalization.

Remains of neosuchian crocodyliforms (isolated teeth, fragment mandibular bone) from the Middle Jurassic (Bathonian) Peski locality in the Moscow Region are described for the first time. The neosuchian from Peski is characterized by well-pronounced ornamentation on the dermal skull bones, and also bicarinate teeth oval in cross section without serration and with triangular conical crowns and fine striation of the enamel. The similarity of Bathonian vertebrate faunas of the Moscow Region, Great Britain, Western Siberia, and Kyrgyzstan is evidence of homogeneity of the vertebrate fauna throughout Laurasia.
