Many nations are adopting smart city applications, which boost residents’ satisfaction with their living conditions and reduce pollution by better-using people’s time resources. Multi-Location parking garages standard in cities because they allow for better access control space allocation to avoid traffic delay complex business areas. The Internet of Things (IoT) has the potential link billions...

natural convection heat transfer from a tube bundle in the indirect water bath heaters is investigated. a computer-code is used for the solution of the governing equations of mass, momentum and energy transfer based on the simple-c algorithm. simulations are carried out for the gas pressure station heater of kermanshah city with various tube bundle arrangements. in order to validate the numeric...

Motor vehicles constitute a significant source of polycyclic aromatic hydrocarbon (PAH) emissions to the atmosphere. Particle-phase priority pollutant PAH concentrations and total suspended particle mass (TSP) were measured in the Lapa bus station and the Americo Simas Tunnel, located in the city of Salvador, Brazil. Separate samples were collected at the bus station at different times of the d...

Œis paper presents SAFEBIKE, a novel route recommendation system for bike-sharing service that utilizes station information to infer the number of available bikes in dock and recommend bike routes according to multiple factors such as distance and safety level. Œe system consists of a station level availability predictor that predicts bikes and docks amount at each station, and an ef€cient rout...

This paper evaluates the effect of the installation of "high-wheel" turnstiles on the incidence of fare evasion at a subway station in New York City. Ridership, summons and arrest data at the treatment station and two adjacent control stations suggest that the new high-wheel turnstiles were somewhat effective in reducing fare evasion, with little evidence of displacement. In light of these resu...

The optimal base station placement and effective radio resource management are of paramount importance tasks in cellular wireless networks. This paper deals with automatic planning of base station sites on a studied scenario, maintaining coverage requirement and enabling the transmission of traffic demands distributed over the area. A city scenario with different demands is examined and the adv...

Abstract This study aims to measure air bacteriological concentration, determine the effect of temperature, humidity, and wind speed on identify genus bacteria found around Gegerkalong waste transfer station. Sampling at stations was based a radius 0, 10, 30 60 meters East, West, South North station 09:00, 12:00 18:30 with 3 replicates. The method used concentration settling plate method. resul...
