Technological Advances and Trends in Modern High-Rise Buildings
buildings Article Technological Advances and Trends in Modern High-Rise Buildings Jerzy Szolomicki 1,* and Hanna Golasz-Szolomicka 2 1 Faculty of Civil Engineering, Wroclaw University of Science and Technology, 50-370 Wroclaw, Poland 2 Faculty of Architecture, Wroclaw University of Science and Technology, 50-370 Wroclaw, Poland * Correspondence: [email protected]; Tel.: +48-505-995-008 Received: 29 July 2019; Accepted: 22 August 2019; Published: 26 August 2019 Abstract: The purpose of this paper is to provide structural and architectural technological solutions applied in the construction of high-rise buildings, and present the possibilities of technological evolution in this field. Tall buildings always have relied on technological innovations in engineering and scientific progress. New technological developments have been continuously taking place in the world. It is closely linked to the search for efficient construction materials that enable buildings to be constructed higher, faster and safer. This paper presents a survey of the main technological advancements on the example of selected tall buildings erected in the last decade, with an emphasis on geometrical form, the structural system, sophisticated damping systems, sustainability, etc. The famous architectural studios (e.g., for Skidmore, Owings and Merill, Nikhen Sekkei, RMJM, Atkins and WOHA) that specialize, among others, in the designing of skyscrapers have played a major role in the development of technological ideas and architectural forms for such extraordinary engineering structures. Among their completed projects, there are examples of high-rise buildings that set a precedent for future development. Keywords: high-rise buildings; development; geometrical forms; structural system; advanced materials; damping systems; sustainability 1. -

City Branding: Part 2: Observation Towers Worldwide Architectural Icons Make Cities Famous
City Branding: Part 2: Observation Towers Worldwide Architectural Icons Make Cities Famous What’s Your City’s Claim to Fame? By Jeff Coy, ISHC Paris was the world’s most-visited city in 2010 with 15.1 million international arrivals, according to the World Tourism Organization, followed by London and New York City. What’s Paris got that your city hasn’t got? Is it the nickname the City of Love? Is it the slogan Liberty Started Here or the idea that Life is an Art with images of famous artists like Monet, Modigliani, Dali, da Vinci, Picasso, Braque and Klee? Is it the Cole Porter song, I Love Paris, sung by Frank Sinatra? Is it the movie American in Paris? Is it the fact that Paris has numerous architectural icons that sum up the city’s identity and image --- the Eiffel Tower, Arch of Triumph, Notre Dame Cathedral, Moulin Rouge and Palace of Versailles? Do cities need icons, songs, slogans and nicknames to become famous? Or do famous cities simply attract more attention from architects, artists, wordsmiths and ad agencies? Certainly, having an architectural icon, such as the Eiffel Tower, built in 1889, put Paris on the world map. But all these other things were added to make the identity and image. As a result, international tourists spent $46.3 billion in France in 2010. What’s your city’s claim to fame? Does it have an architectural icon? World’s Most Famous City Icons Beyond nicknames, slogans and songs, some cities are fortunate to have an architectural icon that is immediately recognized by almost everyone worldwide. -
Wide Dynamic Range Field Strength Meter
Thomas M. Alldread, VA7TA 7056 Railway Ave, Courtenay, BC V9J 1N4, Canada; [email protected] Wide Dynamic Range Field Strength Meter This portable 90-dB dynamic range RF field strength meter is simple to build. While reviewing the specification sheet during normal use this broadband sensitive sensitivity to 200 mA by adding a suitable for the venerable AD8307 logarithmic instrument is very often in close proximity to shunt resistance. The AD8307 and 200 mA RF detector IC, I noticed that the output the sense antenna. Thus an EMI-noisy digital panel meter along with a few surrounding circuit type shown in a block diagram is a design could result in sensitivity-limiting passive components are all that are needed current source. It occurred to me that this residual readings. Additionally, analog to build a reasonably accurate, wide dynamic feature could be easily utilized to drive a meters can be read at a glance and are easy range FSM. conventional analog meter directly. Although to view in bright sunlight — a typical field Expanding the Scale I enjoy building gear that utilizes modern measurement environment. Finally, while After experimenting with the prototype day microcontrollers and wireless devices adjusting equipment to obtain maximum proof-of-concept basic circuit and confirming my thoughts became focused on how simple or minimum signal strength, analog meters that it worked as expected, I decided that it would be to build a wide dynamic range provide a much easier to use peak or null a 10:1 scale expander capability would be field strength meter (FSM) by mixing recent signal strength indicator than a digital beneficial. -

ULTRA FAST SPECTRUM TRIPLE SPLIT DISPLAY LIGHT WEIGHT (< 3 kg) SMART BATTERY CONTROL -2- CHECK COMPARISON TABLE For broadcasters Network delay margin Network planners determine what time instant transmitters should use to broadcast the transport stream bits. They all have to do it at a precise given time, i.e 700 ms in the picture. The difference between the network delay and the required transmission time (700 ms in the example) is called the “network delay margin” and it will be different depending on the specific transmitter location. The lower the 'network delay margin' the higher the chances of that particular transmitter missing the assigned transmission time. Receiving and analyzing T2-MI signals T2-MI is the modulator interface signal used in the 2nd generation digital terrestrial television broadcasting system. It is physically transported to the TV towers using IP or RF and it is accessible via network devices in the form of ASI or IP signals. RANGERNeo can receive a T2-MI signal in both these formats, performing IP transport quality measurements, T2-MI packet analysis and PLP de-encapsulation. -

The system use to detect from transmitters such as in Television, radio broadcasting daylight and night illumination (difference in contrast). stations, telephones etc, hence the strength of field released is Any electric charge object produces an electric field. This high. With these in mind, it is therefore important to design a field has an effect on other charged bodies in the vicinity. field strength meter which determines the amount of electric Electric fields are caused by electric charges or varying field strength around a location. Field strength meter is a measuring device which measures the signal strength caused magnetic fields. When measuring with a field strength by a transmitter. The need for field strength measurement is meter it is important to use a calibrated antenna such as essential when designing and building transmitters. The field such as the standard antenna supplied with the meter. For strength meter provides signal strength figures and allows us precision, measurement the antenna must be at standard to compare and estimate the efficiency of a transmitter and its height. -
