The paper presents an approach to processing of measurement data obtained from ultrasonic system. The approach makes possible to simplify computing of object location. The important advantage of the proposed method is that it eliminates operations on float point numbers. Thus an algorithm based on this approach can be implemented using a simple microcontroller.

In some models of tasks used in the scheduling theory an additional continuously divisible resource is needed to process the task. One of such models, the dynamic one, is considered in the paper. Such model often appears in the real-life situations. Up to date, it was successfully used in many different fields, e.g. scheduling of tasks in the multiple computer systems, the forging process in the steel plants and refuelling of the fleet of boats in a given critical time. In most applications this model is also concave. For such case two phases are distinguished in the methodology of the solution construction. In the fist phase tasks are distributed among the processors and in the second one the resource is (optimally) allotted to the tasks. The second phase is computationally very expensive. Moreover, the methods of the optimal resource allocation proposed so far, although theoretically impeccable, are difficult and in some cases even impossible to apply. Thus in the paper, based on a recent theoretical results we propose a new method of the resource allocation: efficient and easily applicable. This method is compared in the computational experiment to other methods.

In a motion planning of nilpotent nonholonomic systems with the use of the Lafferierre-Sussmann's algorithm it is important to select a representation of motion. In this paper it was established how many P. Hall representations of motion exist. Two methods to determine the number were presented and proved. The number was computed for varied order of nilpotency and the number of generators spanning the system. It appears that many P. Hall representations share the same canonical representation what means that the same point in the state space can be obtained with many trajectories.

From a general form of the Jacobian right inverse for nonholonomic mobile robots we derive a specific Jacobian inverse kinematics algorithm. By design, this algorithm does not involve the mobility matrix, what makes it computationally less demanding than the most often used Jacobian pseudoinverse algorithm. The algorithm has been applied to the unicycle-type mobile robot. It has been shown that the algorithm performs efficiently unless the unicycle moves along a straight line trajectory. Performance of the new algorithm has been illustrated by computer simulations of the unicycle whose controls are synthesized in accordance with either the finite element or the finite difference method.
