Each European Union Member State keeps a register of data on properties located in its territory. The number, type and scope of these properties are determined by each Member State’s needs. The INSPIRE Directive enables the scope of data to be harmonised, and the data to be made available for the purpose of assisting legislators in taking decisions and actions likely to have either direct or indirect impact on the environment. The aim of the study was to indicate the basic differences between the data contained in Polish and Latvian cadastres. Unlike other similar studies analysing the content of data in the cadastre, this article pays special attention to the number of available sets of data about the parcel and its surroundings, the ease of access to these data and the possibility for acquiring them by an interested party without incurring additional fees. This is particularly important in activities related to spatial management and the development of an information society. The results show that in both countries, the decision makers have approached the INSPIRE Directive differently. Direct analyses conducted for the cities of Wrocław (Poland) and Riga (Latvia) demonstrated that the information system in Wrocław contains a considerably greater scope of information available free of charge, is easier to use and offers more services. The Latvian Republic’s spatial information system provides a less-developed scope of information about real estate (without fees) that is dispersed on several websites, which slows down and hinders its use.

This paper presents the design of a versatile mechanism that can enable new directions in amphibious, all-terrain locomotion. The simple, passive, flapped-paddle can be integrated with several structures that are well-suited for locomotion in terrestrial applications. The flapped-paddle overcomes a serious limitation of the conventional flipper where the net lateral forces generated during oscillatory motion in aquatic environments averages out to zero. The flapped-paddle and its mounting, collectively, rests in natural positions in the aquatic environment so as to maximize hydrodynamic force utilization and consequently the propulsive efficiency. The simplicity of the design enabled us to develop a simulation model that concurs well with experimental results. The results reported in the paper are based on integrating the flapped-paddle with the curved leg of the RHex hexapod robot.

5G is a fifth-generation wireless technology that enables extremely fast data transfers and massive connection capacity. Existing Mobile health technology requires more reliable connection power and data transfer rates. The purpose of this research is to design, analyse, and compare the performance of a bio-inspired lotus-shaped microstrip patch antenna array with two to three radiating elements. The proposed antenna utilizes proximity coupled indirect microstrip transmission line feeding technique operating in the 24 GHz-30 GHz frequency band. The results indicate that performance continues to improve as the number of radiating elements increases. Moreover, each radiating element is loaded with complementary and non-complementary split-ring resonators (SRRs). The performance of the proposed microstrip antenna array is then analysed and compared with and without split-ring resonators. The findings validate that the proposed bio-inspired metamaterial-based microstrip patch array antenna is more reliable and performs better than an antenna without SRRs.

This article deals with the issues of the creative process explored by Adam Zagajewski in his writings, especially in his poems forming the cycle of Autoportraits. Indeed, he revisited the subject on numerous occasions, pointing to the importance of inspiration, which, he regretted, received too little attention in today’s world. Be it as it may, in the end it all comes down to the question about how he actually wrote his poems. This article is the first attempt to reconstruct the methods of Zagajewski’s creative work; it also retraces the process of writing a single poem from a poetic note to its final version.
