Adaptation of the Support Frame of the Cooling Skids System for Use in Maritime Transport

Data publikacji: 31 Mar 2016
Zakres stron: 13 - 23

Abstrakt

Abstract

The article presents calculations of the strength of a support frame Skid Cooling units used on oil rigs. The complexity of the equipment does not allow for efficient FEM modeling of such structures. It indicates how to the simplify the model so that the calculations can accepted by the American Bureau of Shipping (ABS).

Analysis of Impact of Disruptions Coming from a Ship on the Accuracy of Determining the Location of the Tracked Air Target by The Modified Optoelectronic Scanning and Tracking Ir Seeker

Data publikacji: 31 Mar 2016
Zakres stron: 33 - 53

Abstrakt

Abstract

The paper presents the results of research whose aim was to specify the impact of disruptions coming from the movement of a ship on the accuracy of determining the location of the tracked target by the modified, optoelectronic scanning and tracking seeker (OSTS). The basic task of OSTS consists in detecting and then tracking closely the detected air target, emitting infrared radiation.

Real -Time Generator of AIS/ARPA/GPS Data

Data publikacji: 31 Mar 2016
Zakres stron: 55 - 67

Abstrakt

Abstract

The paper presents a real-time generator of AIS/ARPA/GPS position data in the standardized NMEA 0183 text format. Position data are produced by a set of various types of ships simulated on the Polish part of the Baltic Sea and are generated on defined IP/UDP addresses and RS-232 ports. In the simulation an extensive set of input parameters is taken into account including the number of particular types of ships, their dimensions, speed as well as parameters of AIS equipments, ARPA radars and GPS receivers. The paper describes the architecture and implementation of the generator. Additionally, it demonstrates the application of the developed generator to test the software developed for the Polish Border Guard.

Estimation of Nakagami Distribution Parameters in Describing a Fading Radio-Communication Channel

Data publikacji: 31 Mar 2016
Zakres stron: 69 - 81

Abstrakt

Abstract

This article presents a review of issues related to the estimation of Nakagami distribution parameters. This distribution is often used for modeling transmission in a fading radio-communication channel, and in addition it well approximates other distributions.

Słowa kluczowe

  • radio-communication fading channel
  • envelope probability distribution
  • estimation of distribution parameters

Assessment of the Possibility of Using Point -To-Point Radio L inks in the Mimo System for Constructing the Local Area Network Backbone

Data publikacji: 31 Mar 2016
Zakres stron: 83 - 93

Abstrakt

Abstract

The article presents the results of the research conducted to assess the possibility of replacing the wiring in the connection system of the local network backbone for constructing backup connections or for the localizations where architectonic conditions do not allow performing installation works related to structural wiring of a building. Testing laboratory environment has been developed using radio devices operating in the IEEE 802.11n standard. The paper reports the results of the transmission tests in the systems of point-to-point links using the MIMO technique to determine parameters of the data transmission performance-throughput and latency. The transfer tests in the MIMO system were conducted in the indoor and outdoor environment.
