This article deals with the influence of the maritime pilot on safety of navigation. The role of the pilot is somewhat marginalized, although his activity is directly related to ensuring the safety of navigation in sea ports, protection of the marine environment and minimizing the risk of collision with ships and port infrastructure. Pilot services have been entrusted to private entrepreneurs who meet certain legal requirements and are subject to supervision by the maritime administration. The article contains a reference to the decisions of the Maritime Chamber in Gdańsk in a case, in which the maritime pilot contributed to an accident in the port of Gdańsk and the analysis of these decisions in the context of the role of the pilot in the safety of navigation in port.

This paper aims to present a new equivalent scheme of multi-windings traction transformers, based on multiport purely inductive circuit. The mathematical background of this equivalent scheme is described. The determination of the different scheme elements is made through a finite-elements calculation of both main and leakage inductances, for the case of a four-winding transformer. A procedure is defined, which allows to estimate the values of these elements from some measurements on the transformer at no-load and short-circuit operations. A specific strategy of short-circuit tests is described, allowing to determine all parameters in a rather simple way.

Maritime freight transport represents an effective solution, allowing to ensure a low-impact

service both under an economic and a sustainable perspective. As a consequence, in the last

ten years, an increasing trend of goods transported by sea has been observed. In order to

improve the terminal containers’ performance, recently published scientific studies shown

the applicability of the ‘lean logistic’ concept as a strategic key for ensuring a continuous

improvement of the logistic chain for inter-/intra terminal containers’ activities. According

to this approach, the adoption of a dry port can positively affect terminal containers’ performance,

but this requires resources and investments due to inter-terminal activities (e.g.

transport of the container from port to dry port and vice versa). The purpose of the study is

to develop a mathematical programming optimization model to support the decision making

in identifying the best containers’ handling strategy for intermodal facilities, according to

lean and green perspectives. Numerical experiments shown the effectiveness of the model in

identifying efficient material handling strategies under lean and green perspective.

Complex structural engineering projects that involve information-gathering and decision-makingprocesses need to be approached with appropriate systems and tools. As transactional databasesare found to be insufficient for this purpose, engineers are adopting multidimensional informationsystems that have been successfully used in other areas of management, especially business.

Port cities are having diff erent spatial structure than those located inlands. As a result of their seaside location, they face specifi c administrative and functional problems on a daily basis. In the economic and settlement structure of the country, they usually play the role of a “gate” through which streams of cargo are distributed further over the whole hinterland. It is the transport and logistics function of port cities, as well as the water bodies located in their area, that determine their spatial character to the greatest extent. The confi guration of the two above- mentioned factors, together with other development conditions, determines the model of spatial changes taking place in port cities. Additionally, evolving shipping technologies aff ect the contemporary development of the ports’ and port cities’ spatial structure.

This article describes security mechanisms used by 3rd-7th layers in OSI/ISO network model. Many of commonly used protocols by these layers were designed with assumption that there are nointruders. Such assumption was true many years ago. The network situation has been changed for last few years and we should realize that some properties of existing protocols may be abused. Moreover, we should exchange some of them or create new versions. There are some methods and guidelines concerning secure programming, but there is also lack of guidelines about creating secure protocols. Authors see the necessity of such guideline and this article is an attempt at analysing existing solutions and selecting some universal and important patterns.

The main purpose of this article is to present facts related to the history of Port Praski located on the right bank of the Vistula river in Warsaw, which is currently being built. The subject of the consideration is the area and development of the former Port Praski, which project and the fi rst works began after the First World War. It’s spatial and functional connections with the downtown area and surroundings are also key issue. The article presents plans, concepts, projects and investments, furthermore theirs level of implementation. Signifi cant eff ort was made to answer the research questions concerning social expectations regarding the function and the direction of Port Praski development. In the final part of the article was made a comparison of existing revitalization works in Port Praski with HafenCity – the district of Hamburg, where the revitalization project has been already implemented for 20 years. However, comparative analysis revealed several signifi cant differences, allowed to conclude that Polish model of revitalization is only a partially identical with the approach applied in Western Europe.

The article attempts a comparison of two harbor districts, in Gdansk and in Hamburg. In 2013, a multiannual program - IBA Hamburg (International Building Exhibition) - was completed. The IBA, initiated with the a concept of the Leap over the Elbe River, part of the Growing City development agenda, addressed the problem of restructuring the port-nearby zones in Harburg and Wilhelmsburg, which have been recognised as areas of high potential in metropolitan development. The concept of metrozones (intra-peripheries or intra border zones), similarly to the term in-between City (German: Zwischenstadt), describes the current problems associated with the strive for creation of an original, but efficient and compact European city. Restructuring of the harbor districts enables new development of the urbanized, but never planned as urban space, areas. Shaped in accordance with the technological capabilities and with the regulation standards and norms of the second half of the 20th century, nowadays the areas form the resultative landscape, burdened with the image of an unfriendly or even dangerous zones. In the era of high technology, metrozones are becoming valuable intra-city developmental areas, opened to alternative urban programs, avoiding the homogenising global trends. In connection with the above, the article describes the situation of the area organized around Nowy Port in Gdansk.

Waterfront regeneration of port districts emerge as a tool for prestigious development of cities in urban re-imaging and growth. Creation of prestigious housing in these areas are part of a broader strategy of mixed-use and property-led development, but in absence of a holistic approach in planning and design, the urban landscapes may be developed merely on basis of the real estate frameworks. This article looks at how development trends of port cities can take an unintended stance in property-led regeneration of port districts, creating gated communities and failing to succeed in achieving the pre-determined objectives in urban planning. The discussion, which will address to issues of place-making, commodification of public space and planning policies, will take the port city of Izmir as the case. It is suggested that the adoption of a holistic approach to urban planning should guide the regeneration processes and design should take place-making into consideration.

Blue infrastructure is not only an element related to rainwater retention in a city but also a factor shaping urban space. As a result of the impact of blue infrastructure on form, function and character of urban space, a unique space is created – an urban blue space. The subject of the article is associated with the blue infrastructure on shape and character of urban spaces, as well as water-land spatial relations within urban blue space. Author of the article analised spatial relations occurring in port cities between aquatic and terrestrial space from perspective of the land, but also water, which is an equally important part of city’s area. As a result models of two-dimensional water-land relations have been recognised and described.

During the 1920s and 1930s Gdynia transformed from a small fishing village into a dynamically developing city through the construction in its vicinity of the largest seaport of interwar Poland. The city’s first expansion plan (1926, Adam Kuncewicz, Roman Feliński), designed for approximately 100 000 inhabitants, had to be revised already within a few years because development of the port has proved to be faster and the terrain requirements of the port substantially greater than originally predicted. In effect grounds originally planned for general city functions were yielded to the rapidly developing port. It was not until 2003 when the port boundaries shifted significantly as a result of restrictions and changes in the nature of port activity. These changes freed around 53 ha of post-harbour sites for new development, attractively located in the immediate vicinity of the existing city centre and waterfront. In 2015 the port boundaries shifted again adding 3 ha more of post-harbour sites. The changes also spurred investment in the north of downtown Gdynia – in accordance with the intentions of first city planners. Ideas how to make good use of post-harbour areas have been invented and evolved since 1990s. The concept which is currently under development was prepared in 2008 by the City Planning Offi ce of Gdynia. Since 2010 analyses and studies of future development have been conducted using 3D model. The concept is continuously updated and new details are added based on projects obtained through architectural competitions. Since 2015 development areas of the northern part of the city center were rebranded as Gdynia Sea City. In accordance with this concept Gdynia Sea City will be the modern city centre with areas designed for leisure, relaxation and business and will be inhabited by more than 10 thousand people. The area’s new grid is a continuation of the urban grid of historical downtown Gdynia and draws upon unrealized city plans of the interwar period. The scale of new buildings in the area is reminiscent of the historical buildings in the area. Groups of higher buildings are allowed outside of a protected area of the historic center, in areas selected through view and cityscape analysis. The residential and commercial complex Sea Towers together with two other newly constructed tall buildings is currently the dominant in this area. Several new development complexes are under construction. Planning concepts assume public availability of quays around the port basins and maintaining spacious openings towards the sea. Construction of marinas is expected using part of the docks and the ability to expand and reduce existing wharves, movement of pedestrians and cyclists between Fishermen Pier and South Pier will be facilitated through the construction of a bridge or a ferry connection. The planned enlargement into the post-harbour areas will double the current potential of Gdynia downtown, and enlarge the scope of representative areas and change the panorama from the historic city center and from the sea. Attractive downtown sites can provide an answer to the issue of uncontrolled urban spill into peripheral areas of adjacent municipalities.

This paper examines the conservation master plan prepared for in Beyoglu, Istanbul’s Galata Persembe Bazaar waterfront and its Genoese and Ottoman port heritage. This paper initially contains an analytical perspective. This perspective informs the analyses of the evolution of planning process on the conservation of the port heritage. The results of relations between port heritage and conservation planning works have come up for discussion. Spatial interventions on the Persembe Bazaar waterfront began in the 1980s by removing industrial and commercial buildings in the area. These interventions, made in the framework of wiping away the Halic (Golden Horn) waterfront created pressure for urban regeneration in areas with historical and cultural heritage assets like Persembe Bazaar. Major projects such as Galataport and Halicport on the waterfronts of the Halic and the Bosphorus have increased this pressure. Huge functional transformations on the waterfront are desired along with the Persembe Bazaar Conservation Master Plan, which conforms neither to the content nor the context of general conservation principles or Turkey’s conservation legislation. Its content includes no interventions compatible with the theme of “living in harbour cities” and should thus be criticized. The conservation of the tangible and intangible heritage of historical port features, the preservation and development of the service sector and trade in the area requires adopting a holistic understanding of conservation and taking historical features into account. Such an important port heritage site should not be seen as having only touristic functions. It should emphasize more local features for their daily use of local residents and businesses.

This article examines the ontological and spatial character of the waterfront and its influence on perception and design, with particular focus on the process of reproduction of space (Lefebvre) through the generation of mental maps. The convergence of land and water holds in itself an inherent tension between the accessible and the unattainable: the unconscious can be projected on the unknowable underwater space; the unseen domain beyond the horizon can hold a promise of a better world. Another polarity is that of the familiar and the unknown/exotic, off ering a new perspective, a reevaluation of the familiar through the process of ‘ostranenie’ (Shklovsky),’verfremdung’ (Brecht) or ‘estrangement’. The impact of these polarities reaches beyond the spectacle of urban life, the cinematic experience or the theatrum mundi: it enables the reevaluation of the preconceptions of beauty and utility, as exemplifi ed by Futurist Manifesto (Marinetti). These polarities manifest themselves in the hierarchy and dynamics of a waterfront community: physical impermanence of water dwellings foregrounds the contingent nature of human relationships. The waterfront community inhabits superimposed yet separate networks of land and water. First, mental maps have to be generated for each of these separately, then they have to be reconciled in a coherent whole in a separate process. That mapping of the separate networks necessitates a physical transition, a spatial translation that also has linguistic consequences: a different semantic field is assigned to the vocabulary of the everyday, for the significance of the basic terms like ‘home’ or ‘street’ need a modifi ed definition. All the aforementioned processes and phenomena infl uence the ability to perceive, design and reproduce waterfront areas of cities.

In this paper a design of millimeter-wave six-port device for LTCC (Low Temperature Cofired Ceramic) technology is presented. Furthermore, problems with implementation of the project taking into account requirements of LTCC technology are discussed.

The article deals with the process of restoring life into the Elblag’s waterfront – located in the heart of the city, which is the Old Town with still forgotten Granary Island, both damaged by the second world war. The conclusions are inspired by publications about Elblag deriving from various periods, as well by international or students’ workshops. The author describes various considerations how to bring Granary Island into cultivation simultaneously with rebuilding Elblag’s Old Town, that derive from the conservation concept based on a new method named retroversion, how to create new panorama of the waterfront and what is the best way to integrate it with The Old Town, using Elblag River.
