High Line je jedním z nejnavštěvovanějších veřejných prostorů na světě. Denně sem směřují tisíce lidí, aby si ověřili zážitek z přírodně koncipovaného parku, procházejícího napříč galerijní čtvrtí západního Manhattanu. V době, kdy ho architekti Ricardo Scofi dio a Matthew Johnson ze studia Diller Scofi dio + Renfro, ve spolupráci s Pietem Oudolfem a s Jamesem Cornerem (Field Operations) koncipovali, neexistovalo ještě velké množství obdobných příkladů. Sedm let po dokončení první fáze parku lze již hovořit o téměř šedesáti realizovaných projektech inspirovaných úspěchem High Line (Corner et al., 2015). O tom, jaké byly záměry autorů při rekonstrukci této jedinečné dopravní konstrukce a jaká byla úskalí designu celé realizace v kontextu její udržitelnosti, mnohé napoví rozhovor, který se uskutečnil s architekty Ricardem Scofi diem a Matthew Johnsonem 2. listopadu 2015 v newyorském studiu Diller Scofi dio + Renfro se sídlem v budově Starrett–Lehigh (v západní části Chelsea na 26. ulici). Rozhovor s autory architektonického řešení parku High Line, architekty Ricardem Scofi diem a Matthew Johnsonem, uzavírá sérii tří interview s tvůrci a plánovači veřejných prostorů a parků v New Yorku. New York’s High Line is one of the most visited public areas in the world. Thousands of people go there every day to experience a nature-based park in the gallery quarter of West Manhattan. There had not been many of such places at the time when Ricardo Scofi dio and Matthew Johnson of the Diller Scofidio + Renfro studio designed the park in cooperation with Piet Oudolf and James Corner. It is said that almost sixty projects, inspired by the success of High line Park, were carried out over the fi rst seven years after the completion and opening of the High Line. The intentions of the designers for the reconstruction of this unique transportation structure and the difficulties with implementing the project in the context of sustainability were the focus of an interview with designers Ricardo Scofi dio and Matthew Johnson, conducted on 2 November 2015 in the Diller Scofidio + Renfro studio in the Starrett–Lehigh Building in Chelsea, New York. This interview concludes a series of three interviews with the planners and developers of public areas and parks in New York.

The contribution deals with design and analysis of controllable second-order frequency filter which operates in the current mode and where the main element is the current amplifier DACA (Digitally Adjustable Current Amplifier) and also MOTA (Multiple Output Transconductance Amplifier) is used. The paper presents a description of the proposed circuit and results of computer simulations for circuit in single-ended and fully-differential variant. Four simulation models with different properties were used for simulating of the DACA active element in the proposed circuit.

Phoebe Apperson Hearst měla velmi úspěšného vlastního syna Williama, který byl ale více jako jeho otec: tvrdý obchodník. Našla však jemnou, uměleckou duši v malíři Orrinu Peckovi (1860–1921), který byl údajně gay a který ji, ještě za života své vlastní matky, začal oslovovat „má druhá mámo.“ Na základě podrobného výzkumu jejich vzájemné korespondence v Peckově pozůstalosti se můžeme ptát, jak moc si byla progresivní, bohatá žena 19. století, jakou byla Phoebe Hearst, vědoma Peckovy sexuality a pokud ano, jestli s tím neměla problém, nebo šlo o nevyřčené tajemství mezi nimi? Jejich příběh představí historik umění Ladislav Zikmund-Lender. Phoebe Apperson Hearst had a very successful son of William, but he was more like his father: a tough businessman. However, she found a delicate, artistic soul in the painter Orrin Peck (1860–1921), who was allegedly gay and who, while still his own mother's life, began to address her as “my second mother.” Based on a detailed study of their correspondence in Peck's estate, we may ask how much a progressive, rich 19th-century woman like Phoebe Hearst was aware of Peck's sexuality, and if so, if she had no problem with it, or was it an unspoken secret between them? Their story will be presented by art historian Ladislav Zikmund-Lender.

This paper deals with proposed 2nd order universal frequency filter. In design of this frequency filter, multiple-output current follower (MO-CF) and digitally adjustable current amplifier (DACA) have been used. The frequency filter is proposed with ability to control the pole frequency without disturbing the selected quality factor by parameter of DACA active elements in form of integrated circuit. Design is supported by simulation and also measurement results.

In 1939, due to WWII and the Nuremberg Laws, the revolutionary Czech structural engineer Jaroslav J. Polívka arrived in the United States. After his arrival, he started a research job at UC Berkeley, renewed his engineering practice, and offered his services to the US military as many businesspersons did during this era. Polívka worked for Henry Kaiser who turned Richmond, CA, into a vibrant, fast developing workers city. New residential districts, hospitals, hangars, docks, and warehouses were built there. Henry Kaiser approached the structural development of the city in the same way he revolutionized the construction of battleships: from prefabricated, standardized parts. He supported research and development of new technologies. Mobile, round-shaped hospitals from prefabricated aluminum frames were one of the results of that research. In 1946, Jaroslav J. Polívka introduced himself to the “starchitect” Frank Lloyd Wright. A productive mutual co-operation that lasted 13 years and resulted in eight spectacular projects had started and Polívka, who had been working on extensive research both at UC Berkeley and Stanford University, came up with many technological, structural, and material innovations over the period. In 1957, Henry Kaiser funded the construction of one of the two geodesic domes designed by Richard Buckminster Fuller in Hawaii and in the process he invited Frank Lloyd Wright to consult the project. Jaroslav J. Polívka was probably in direct contact with Fuller, since he wanted to include him in his unfinished project of an encyclopedia of the world-famous structural engineers. On this particular story and a social matrix evolving around Henry Kaiser and Frank Lloyd Wright, the lecture seeks to rethink architectural global modernism as a cooperative project rather than a series of individual innovations manifested by isolated genius figures.

A new fully-differential (F-D) filtering structure of the 2nd-order current-mode universal filter is described in this paper. Presented filter is also proposed in a single-ended (S-E) form in order to compare behavior of single-ended and fully-differential structures. Signal-flow graphs method is used to design both presented filters. Multi-output transconductance amplifiers (MOTAs), digitally adjustable current amplifier (DACA), multi-output current follower (MO-CF) and fully differential current follower (FD-CF) were used in proposal. Filters possess of ability to adjust their pole frequency and quality factor independently of each other. The actual function of proposed filters has been verified by PSpice simulations and experimental measurements.

Image similarity measuring has many various applications. Pedestrian recognition is one of them and for the security purposes it is basically required to run in real-time. This paper proposes a deep Siamese neural network architecture for pedestrian recognition that achieves 70.28% accuracy on the test set containing 20 persons. Prediction of the model is fast enough for real-time processing.

The paper explores parallels and relations between cities – centres of thinking – which, in their time, used to set the trend, and where new lines of thought originated (not every large city was a centre of thinking; this depended on certain circumstances and social determinants). The timeline of the cities’ development is followed – from their beginning, through their rise and heyday, to their fall – in the global context. Is fall a necessary part? Is it definitive?
