Abstract

The article is an attempt of providing basic information on the Polish Register of Ships – (rejestr okrętowy), its legal principles, construction and mode of operation. The text is by no means a comprehensive legal analysis of this institution – such a study would have necessitated much more time and effort, but it is rather a synthetic guidance on how the register is designed, how it works, or at least how it should have worked and what sort of purposes it primarily serves. The publication reflects a present status of legislation in Poland, i.e. the respective regulations of the Polish Maritime Code enacted in 2001. It should be noted that a draft of a new Polish Maritime Code has recently been prepared, that designs the Polish Register of Ships in a slightly different, more flexible and up-to-date, mode. However, at the moment, we are not able to predict when the new regulations might be enacted and become applicable. Polish maritime hypothecation and mortgage are subject to a separate study that shall be presented in the near future.

Abstract

A parcel is the most important object of real estate cadastre. Its primary spatial attribute are boundaries, determining the extent of property rights. Capturing the data on boundaries should be performed in the way ensuring sufficiently high accuracy and reliability. In recent years, as part of the project “ZSIN – Construction of Integrated Real Estate Information System – Stage I”, in the territories of the participating districts, actions were taken aimed at the modernization of the register of land and buildings. In many cases, this process was carried out basing on photogrammetric materials. Applicable regulations allow such a possibility. This paper, basing on the documentation from the National Geodetic and Cartographic Documentation Center and on the authors’ own surveys attempts to assess the applicability of the photogrammetric method to capture data on the boundaries of cadastral parcels. The scope of the research, most importantly, included the problem of accuracy with which it was possible to determine the position of a boundary point using photogrammetric surveys carried out on the terrain model created from processed aerial photographs. The article demonstrates the manner of recording this information in the cadastral database, as well as the resulting legal consequences. Moreover, the level of reliability of the entered values of the selected attributes of boundary points was assessed.

Abstract

After an introduction (§1), all the Ugaritic terms for occupations, professions and social classes are set out in a classified list together with their cognates in other Semitic languages and their equivalents in Afro-Asiatic, Indo-European and other language groups (§2). There are also sections on composite expressions (§3) proper nouns (§§4–5) and both syllabic Ugaritic and Ugaritian Akkadian terms in these categories (§6). A table sets out the results (§7), with statistics for distribution (§8) and language (§9) and finally there are some conclusions (§10).

Abstract

This paper provides an overview of the effects of timing jitter in audio sampling analog-to-digital converters (ADCs), i.e. PCM (conventional or Nyquist sampling) ADCs and sigma-delta (ΣΔ) ADCs. Jitter in a digital audio is often defined as short-term fluctuations of the sampling instants of a digital signal from their ideal positions in time. The influence of the jitter increases particularly with the improvements in both resolution and sampling rate of today's audio ADCs. At higher frequencies of the input signals the sampling jitter becomes a dominant factor in limiting the ADCs performance in terms of signal-to-noise ratio (SNR) and dynamic range (DR).
