Introduction. Traction power of the car is used to determine its traction-speed properties. The purpose of the paper is the calculation refinement of the car traction power.Materials and methods. The authors used the methodology of the refined calculation of the car traction power.Results. The authors carried out the comparative analysis of the refined and traditional methods for calculating traction power. As a result, the authors obtained the refined equation for calculating the traction power, taking into account the elastic modulus, the width of the contact track, the free radius of the wheel, the deflection of the tire and the tangential friction forces in the contact zone. The largest discrepancy between the curve of the vehicle’s traction power calculated by the updated methodology and the curve of the vehicle’s traction power calculated by the traditional method was 26.8%.Discussion and conclusions. The results of the research are useful to specialists of automobile and transport enterprises and masters of universities to compare the traction and speed properties of the various car types.

The Future

Handwriting is a method to express and preserve thoughts by means of graphic signs. In the investigative and judicial practice, it is treated as an individual creation used for identification purposes in case of doubts over the authenticity of a written record. Nowadays, however, writing by hand is not the only way of conveying information, which results in moving away from this traditional method in favour of modern solutions. In the future, this tendency may limit the possibility to identify the author of a record on the basis of a handwritten record. Therefore, the purpose of this publication is to check whether contemporary handwritings show any signs of deterioration in the quality of handwritten records.

The characters, research and utilization of Ground Granulated Blast Slag are presented in this paper. Some current use of GGBS in soft soil treatment is introduced. In addition, the paper also focuses on the comparative analysis of the effects of GGBS and Lime Stabilization which is the traditional method in soft soil treatment on compaction characteristics & Atterberg limits. Next, the strength mechanism of GGBS, a kind of Soli Stabilizer applied in soft soil treatment, is mainly explained and also the validity of GGBS has been proved. All of these indicate that GGBS has the superiority of social benefit, economic benefit and environmental benefit in soft soil treatment.

Generalized assignment problem (GAP) considers finding minimum cost assignment of n tasks to m agents provided each task should be assigned to one agent only. In this study, a new Genetic Algorithm (GA) with some new methods is proposed to solve GAPs. The agent-based crossover is based on the concept of dominant gene in genotype science and increases fertility rate of feasible solutions. The solutions are classified as infeasible, feasible and mature with reference to their conditions. The new local searches provide not only feasibility in high diversity but high profitability for the solutions. A solution is not given up through maturation-based replacement until it reaches its best.  Computational results show that the agent-based crossover has much higher fertility rate compared to classical crossover. Also, the proposed GA creates either optimal or approximately optimal solutions.

We introduce a discrete random process which we call the passenger model, and show that it is connected to a certain random model of the assignment problem and in particular to the so-called Buck–Chan–Robbins urn process. We propose a conjecture on the distribution of the location of the minimum cost assignment in a cost matrix with zeros at specified positions and remaining entries of exponential distribution. The conjecture is consistent with earlier results on the participation probability of an individual matrix entry. We also use the passenger model to verify a conjecture by V. Dotsenko on the assignment problem.
