The research is devoted to the development of an automatic complex that is being transformed with an autonomous power system. . This problem is now the most urgent one because the bicycle has become one of the ultra-high-speed vehicles in a big city.In this work, the experimental design of an automated bicycle parking is considered: a gripping device that must capture the bicycle and hold it during transportation to the storage place inside the parking lot; a device for lifting and transporting, provides lifting and moving the vehicle during operation; place of direct storage of vehicles. Moving element - the automated operator’s boom is equipped with a surveillance camera so that so that the user has the opportunity to monitor the operation of the system personally on the screen of the control panel. To ensure ease of construction, the main part of the operator is made of aluminum, which gives a preference for lightness by 40%, in contrast to the Steel counterpart, while maintaining the same strength. It also makes it possible to use engines of lower power and lower weight, as a result of which the design is cheaper. During the development of automated bicycle parking, a module of the solar power station was added, this made it possible to ensure autonomous operation of the system. The developed design has several sizes, starting from the basic one level and ending with the maximum possible five levels, so the system capacity changes, from 120 to 600 seats. In addition to various types of bicycles, automated bicycle parking may include different variety of electric scooters of the proposed design and weight.The resulting design of an automated modular bicycle parking is higher than existing analogues, automated bicycle parking is higher by two times, and in saving space by three and a half times. Also, the modularity of the design is unique and has no analogues now. The use of alternative technologies allowed us to make the system autonomous and ecological, which allows us to place it both in the city center and in the forest conservation area or Ecopark

Laboratory automation is a key driver in biotechnology and an enabler for powerful new technologies and applications. In particular, in the field of personalized therapies, automation in research and production is a prerequisite for achieving cost efficiency and broad availability of tailored treatments. For this reason, we present the StemCellDiscovery, a fully automated robotic laboratory for the cultivation of human mesenchymal stem cells (hMSCs) in small scale and in parallel. While the system can handle different kinds of adherent cells, here, we focus on the cultivation of adipose-derived hMSCs. The StemCellDiscovery provides an in-line visual quality control for automated confluence estimation, which is realized by combining high-speed microscopy with deep learning-based image processing. We demonstrate the feasibility of the algorithm to detect hMSCs in culture at different densities and calculate confluences based on the resulting image. Furthermore, we show that the StemCellDiscovery is capable of expanding adipose-derived hMSCs in a fully automated manner using the confluence estimation algorithm. In order to estimate the system capacity under high-throughput conditions, we modeled the production environment in a simulation software. The simulations of the production process indicate that the robotic laboratory is capable of handling more than 95 cell culture plates per day.

This study analyses the changes in intra-city housing values in response to improved inter-city connection brought by high-speed rail (HSR), using the opening of the Hangzhou–Fuzhou–Shenzhen Passenger Dedicated Line (HFSL) in Shenzhen, China, as an example. The opening of the HFSL and its integration into the local metro network at Shenzhen North Station provide exogenous intra-city variations in access to the surrounding economic mass. With a difference-in-differences approach, we find that the HFSL showed a negative local effect as housing values declined by 11.5%–13.3% in the proximity of Shenzhen North Station relative to areas further from the station after the opening, possibly due to the negative externalities of the HFSL. The HFSL effect can spread along the metro network and lead to, on average, a 7% appreciation of housing values around metro stations (network effect). The direction and strength of the network effect vary by metro travel time between Shenzhen North Station and metro stations. Housing values decreased by 7.7% around metro stations within 5–15 minutes of metro travel time but increased by 63.6%, 16.6% and 29.2% around metro stations within 15–25, 25–35 and 35–45 minutes of metro travel time to Shenzhen North Station, respectively. The HFSL effect on housing values diminishes when the rail travel time is above 45 minutes. We interpret these findings as evidence of the redistribution effect in the city related to HSR connection.

Parking difficulty is being a highlighted problem in nowadays' cities. As a reality of planning of parking lots in Chinese cities are later than other countries, and also parking lot planning are based on city blueprint and needs of parking places, as well as limit of making parking lot plan, we can make a model on planning and choosing parking lot fields to find the most suitable scheme. Thus it can bring the greatest benefit to the whole area in the city, and also make a reference to planning of the parking lot construction in area.

The Bukit Tangkiling Conservation Area has great potential for natural resources, including clean water, honey bees, recreation services, and religious services. There is also potential for split stone, which had been mined by the people from the rock hills in the area. The potential utilization of these natural resources trigger conflicts between interests to maintain the function and existence of conservation areas with the interests of using split stone for the community in order to meet the development needs of the city of Palangka Raya and its surrounding regions, at the cost of damaging the existing area. As an input in managing the conservation area Bukit Tangkiling is well implemented, research is needed on the social and economic conditions of the community’s surrounding the area. The research used survey methods and respondents are determined by purposive sampling and simple random sampling, and data analysis was both qualitative and quantitative. The communities around the Bukit Tangkiling conservation area are dominated by productive age (18-56 years), Banturung Village 59.00% and Tangkiling Village 54.97%. The level of education is relatively low, Banturung Village 72.96% and Tangkiling Village 73.29%. Having low education, most of the people have difficulty in finding decent work. Aside from that, most people do not understand the function of the forest or the function of the conservation area and tend to be apathetic about the existence of the Bukit Tangkiling conservation area that must be preserved. For some of these poorly educated people, the work of mining rocks is the best alternative to meeting the economic needs of the household. Income obtained from mining rock ranges from 2-4 million IRD per month.

ABSTRACT  Related to the implementation of the Regional Regulation (Perda) about the increase in parking rates at the edge of the road prone to congestion in the city of Bogor ratified and entered into force on July 2, 2012, The first location that imposed this tariff is the Way Suryakencana and Jalan Siliwangi Bogor and the second location is the application of The Government through the Department trials Traffic Transportation (DLLAJ) Bogor City gets a reaction from the people around Jalan Suryakencana. Enactment of the increase in parking rates at Jalan Bogor Suryakencana expected to reduce illegal parking of vehicles in the area, which has been causing congestion. With parking rates that have been enacted many road users who park their vehicles in multiple and indiscriminate. The method used in this study is empirical juridical approach. The study, based on an inventory of positive law, the discovery of the principles of law and legal discovery inconcretto, which include observation of empirical operationalization of law in society. The conclusion from this study is the basis of the application of the levy Parking Services Bank Public Road, especially in the city of Bogor is Law No. 28 of 2009 on Regional Taxes and Levies and Regional Regulation No. 4 of 2012. Implementation of Regional Regulation No. 4 of 2012 on Increase Rates Parking is not yet fully effective this is due to high payments also has not been matched with adequate services, the responsibility for the damage and loss still be a burden for the owner of the vehicle so that the functions and responsibilities of the government that deal with parking problems is questionable. Impact parking tariff policy to demand that any increase in the parking rate of 10 percent would result in a decrease in the use of parking of 0.7 -0.8 percent, increase use of public transport and cycling amounted to 3.71 percent of 0.9 percent. This figure is even greater in the short term, when applied can lead to a new increase in the elasticity to be about - 0.28., Where the parking lot reducing the length of parking time and reduce the amount of parking.  Keywords: Regional Regulation, Rates Parking, Traffic Order

Transport Transition

Within the renewable transport transition, a number of alternative technologies have emerged creating competing visions of how to reduce fossil fuel dependence. This paper examines the dynamics of competing fuels in two Swedish municipalities where electric buses have emerged, threatening incumbent biogas-based bus systems. While in Linköping, actors are resistant to the promise of electrification, in Malmö the shift to electrify urban buses has already begun. Here, the theoretical perspectives of obduracy and sociotechnical imaginaries are used to analyze obduracy and change in Linköping and Malmö, showing how the local contexts of these two municipalities influence obduracy or willingness to change. In Linköping, perceived connections between the biogas-based bus system and local infrastructures of renewable waste management and organic food production cause actors to place biogas buses at the center of a sustainable future region, while in Malmö linkages to the gas network (which also distributes natural gas) cause actors to question the sustainability of the fuel in use and opens up the city to welcome new electric vehicle tests. These examples show how fuel alternatives interact with each other in the wider renewable energy transition.

This work concerns Vicenza, a city located not far from Venice in the north-east corner of Italy, and it specifically refers to an area situated on the outskirts of the city’s urban fabric between the perimeter of its ancient walls and the banks of the Bacchiglione river, in the shadow of the abandoned monastery of St. Biagio. The idea of restoring that physically and socially degraded area of the city of Vicenza has long been the object of discussion on the part of local authorities. Once intimately linked to the city’s historic center, the area gradually lost its functional and social identity becoming first a parking lot and then equipped as a city warehouse. The intent to regenerate the area and the observation that the relationship between the city and its river is constantly refused, or delayed, lead to recognize in the long edge of the area a unique meeting opportunity which allows to repair the water-city association, recuperating rituals and connections from the past. The municipality is presently planning on pursuing a qualitative restoration of the area which will be used for social and cultural enrichment. The final part of the current work outlines some proposals that were developed during the Architectural and Urban Composition 2 course recently offered by the Department of Civil, Environmental and Architectural Engineering of the University of Padua (Italy).

Magnetic levitation (maglev) is a highly advanced technology which provides, through magnetic forces, contactless movement with no wear and friction and, hence, improved efficiency, followed by reduced operational costs. It can be used in many fields, from wind turbines to nuclear energy and elevators, among others. Maglev trains, which use magnetic levitation, guidance and propulsion systems, with no wheels, axles and transmission, are one of the most important application of the maglev concept, and represents the first fundamental innovation of rail technology since the launch of the railroad era. Due to its functional features, which replaces mechanical components by a wear free concept, maglev is able to overcome some of the technical restrictions of steel-wheel on rail (SWR) technology, running smoother and somewhat quieter than wheeled systems, with the potential for higher speeds, acceleration & braking rates and unaffected by weather, which ultimately makes it attractive for both high speed intercity and low speed urban transport applications. From a technical perspective, maglev transport might rely on basically 3 technological concepts: i) electromanetic suspension (EMS), based on the attraction effect of electromagnets on the vehicle body, that are attracted to the iron reactive rails (with small gaps and an unstable process that requires a refined control system); ii) Electrodynamic Levitation (EDL), which levitates the train with repulsive forces generated from the induced currents, resulted from the temporal variation of a magnetic field in the conductive guide ways and iii) Superconducting Levitation (SML), based on the so called Meissner Effect of superconductor materials. Each of these technologies present distinct maturity and specific technical features, in terms of complexity, performance and costs, and the one that best fits will depend on the required operational features of a maglev system (mainly speed). A short distance maglev shuttle first operated commercially for 11 years (1984 to 1995) connecting Birmingham (UK) airport to the the city train station. Then, high-speed full size prototype maglev systems have been demonstrated in Japan (EDL) (552 kph - 343 mph), and Germany (EMS) (450 kph - 280 mph). In 2004, China has launched a commercial high speed service (based on the German EMS technology), connecting the Pudong International Airport to the outskirts of the city of Shanghai. Japan has launched a low speed (up to 100 kph - 62.5 mph) commercial urban EMS maglev service (LIMINO, in 2005), followed by Korea (Incheon, in 2016) and China (Changsha, in 2016). Moreover, Japan is working on the high speed Maglev concept, with the so called Chuo Shinkansen Project, to connect Tokio to Nagoya, in 2027, with top speeds of 500 kph (310 mph). China is also working on a high speed maglev concept (600 kph - 375 mph), supported on EMS Maglev technology. Urban Maglev concept seeks to link large cities, with their satellite towns and suburbs, to downtown areas, as a substitute for subways, due to its low cost potential, compared to metros and light rail (basically due to their lower turning radius, grade ability and energy efficiency). High Speed Maglev is also seen as a promising technology, with the potential do provide high quality passenger transport service between cities in the 240–1,000 km (150–625 mi) distance range into a sustainable and reliable way. This work is supposed to present, based on a compilation of a multitude of accredited and acknowledged technical sources, a review of the maglev transport technology, emphasizing its potential and risks of the low and high speed (urban and intercity) market, followed by a brief summary of some case studies.

Performance Results

Quiet submarine threats and high clutter in the littoral undersea environment increase the processing demands on beamforming arrays, particularly for applications which require in-array autonomous operation. Whereas traditional single-aperture beamforming approaches may falter, the Split-Aperture Conventional Beamforming (SA-CBF) algorithm can be used to meet stringent requirements for more precise bearing estimation. Moreover, by coupling each transducer node with a microprocessor, parallel processing of the split-aperture beamformer on a distributed system can glean advantages in execution speed, fault tolerance, scalability, and cost. In this paper, parallel algorithms for SA-CBF are introduced using coarse-grained and medium-grained forms of decomposition. Performance results from parallel and sequential algorithms are presented using a distributed system testbed comprised of a cluster of workstations connected by a high-speed network. The execution times, parallel efficiencies, and memory requirements of each parallel algorithm are presented and analyzed. The results of these analyses demonstrate that parallel in-array processing holds the potential to meet the needs of future advanced sonar beamforming algorithms in a scalable fashion.
