+ - ABSTRACT Click to collapse

The paper presents a project of a street lights intelligent system, which allows for public savings, as a result of more efficient roads and pavements lights management. The system would operate based on the current location of vehicles and pedestrians. Because of this no additional costs or devices are required in smartphones or modern vehicles to indicate its location, as smartphones, smartwatches and most of modern cars are equipped with the GPS modules. But each smart street lamp needs to be equipped with a little module that communicates with the central system and which controls the work of lighting.

+ - ABSTRACT Click to collapse
The paper discusses a numerical investigation, using a CFD tool, ANSYS FLUENT, of drag acting on a motorcycle helmet. The simulations were performed on a model of a helmet downloaded from a free CAD model library. A solid model enabled us to generate a mesh, to define boundary conditions and to specify a model of turbulence. Accordingly, the values of forces acting on individual sections of the helmet were obtained and the coefficients of aerodynamic drag were calculated. The test results can be used to optimize the shape of the existing motorcycle helmet construction and to study the impact of generated drag forces on reaction forces affecting a motorcyclist’s body.

ASYNCHRONOUS INFORMATION DISTRIBUTION AND CLUSTER STATE SYNCHRONIZATION

Maciej NABOŻNY
Print
+ - ABSTRACT Click to collapse
This article describes issues related to information distribution and cluster state synchronization in environments with inconsistent network topology (with partially connected nodes or disconnected), without centralized authentication and authorization points. The main objective of this study was to create a set of rules and functional requirements to build a framework for building applications in decentralized and distributed environments that are not fully fault-tolerant, regardless of the underlying cluster’s hardware topology and availability. These solutions are based on selected principles known from the Blockchain database, Public Key Infrastructure, and Event Driven Development. Functional requirements derived from these systems are the basis of a framework dedicated for creating decentralized systems and distribution of information, used in systems developed by cloudover.io company together with AGH University of Science and Technology. Proposed principles were implemented as free library – libdinemic, which is base for future cluster management system, dedicated for large and inconsistent environments.

THE USE OF SIMULATION ENVIRONMENT FOR SOLVING THE ASSEMBLY LINE BALANCING PROBLEM

Wojciech DANILCZUK
Print
+ - ABSTRACT Click to collapse
The paper describes the application of a simulation environment (Tecnomatix Plant Simulation) for solving a real manufacturing problem. The studied case consisted in rebalancing the production line with a specified number of operators on the line. The first stage of the study involved determination of the production cycle and key performance indicators. The production system was then divided into work cells. After that, proposed design assumptions were verified via a simulation model.

+ - ABSTRACT Click to collapse
Fluctuationinprices of Agricultural products is inevitable in developing countries faced with economic depression and this, has brought a lot of inadequaciesin the preparation of Government financial budget. Consumers and producers are poorly affected because they cannot take appropriate decision at the right time. In this study, Machine Learning(ML) predictive modeling is being implemented using the MATLAB Toolboxto predict the price of cassava derivatives (garri) in the SouthWestern part of Nigeria.The model predicted that by the year 2020, all things being equal,the price of (1kg) of garri will be N500.This will boost the Agricultural sector and the economy of the nation.
