Technical Aspects of Using the Heat Pump at the Ship

Pubblicato online: 28 Jun 2019
Pagine: 5 - 15

Astratto

Abstract

The paper attempts to analyze the technical possibilities of using a compressor heat pump to recover waste heat from energy processes implemented by a watercraft. The amount of waste heat that could be used for the heating needs of the vessel was estimated and the hydrothermal potential of the marine waters was assessed. The possibilities of reducing the power of the ship's power plant used to power the ship's heating installation were determined.

Using Gamification and Fear Appeal Instead of Password Strength Meters to Increase Password Entropy

Pubblicato online: 28 Jun 2019
Pagine: 17 - 33

Astratto

Abstract

It is very common for users to create weak passwords. Currently, the majority of websites deploy password strength meters to provide timely feedback. These meters are in wide use and their effects on the security of passwords have been relatively well studied. In this paper another type of feedback is studied: a gamified approach supported by fear appeal. In this approach, users are encouraged to make passwords stronger through the use of visual and textual stories. This approach is supported by data-driven suggestions about how to improve password security as well as by fear appeal. To prove the effectiveness of this gamified password creation process, an experiment was performed in which users changed their passwords in two ways: without any feed-back, and with gamified feedback with fear appeal. To support the initial findings a questionnaire was completed by participants at the end of research.

Polish Navy Shipbuilding Regulations — Example of Neglect and Lack of Awareness. Polemical Sketch

Pubblicato online: 28 Jun 2019
Pagine: 49 - 68

Astratto

Abstract

The paper presents a formal and legal status within the scope of design, construction and equipping the Polish Navy ships. Regulations in force in the Ministry of National Defence are not complete and have a significant impact on the possibilities and limited efficiency of building new ships.

The article presents an attempt to systematise issues in terms of the construction of new ships for the Polish Navy. Fundamental attention was focused on identification of existing gaps in the regulations, as well as presenting proposals to eliminate them.

Changes in the Logistics System of the Polish Navy

Pubblicato online: 28 Jun 2019
Pagine: 69 - 79

Astratto

Abstract

The aim of the article is to show the changes taking place in the structures of logistical support of the Polish Navy, focusing on the changes in the way of supplying ships of the Polish Navy. In recent years, the Polish Navy has undergone many changes in the subject matter, starting from the liquidation of the Logistics of the Polish Navy and the Polish Navy Command, including the Management of Logistics Planning. The changes contributed to the centralization of Logistics, creating the Inspectorate for Armed Forces Support of the Republic of Poland, which focused on the main burden of tasks related to, among others, repairs, modernization and supply of ships. On the other hand, it extends the time of issuing opinions on, for example, the protocols for assessing the technical condition of military equipment (ME), which are the basis for the replacement, repair or further exploitation of the ME.

Text Spotting in the Wild with Embedded Device

Pubblicato online: 28 Jun 2019
Pagine: 81 - 95

Astratto

Abstract

Detecting and recognizing text in natural scenes (e.g. streets, restaurants, shops, etc.) could be a part of an artificial intelligence system, especially with regard to the speech synthesis system. Properly detected text is passed to a recognition stage and then to the speech synthesis system, which translates text to speech. Research is carried out for the ‘Toucan Eye’ project — embedded device with artificial intelligence system able to help people with impaired sight. Due to constrained resources and abilities of embedded devices, criteria for text spotting must be met. First criterion is quality of detected and recognized regions with text and the second is time spent on both operations. Particular stages of the system and chosen methods of text spotting under aforementioned constraints are presented.
