Smart transportation a smart city application where traditional individual models are transforming to shared and distributed ownership. These models are used to serve commuters for inter- and intra-city travel. However, short-range urban transportation services within campuses, residential compounds, and public parks are not explored to their full capacity compared to the distributed vehicle model. This paper aims to explore and design an adequate framework for battery-operated shared mobility within a large community for short-range travel. This work identifies the characteristics of the shared mobility for battery-operated vehicles and accordingly proposes an adequate solution that deals with real-time data collection, tracking, and automated decisions. Furthermore, given the requirement for real-time decisions with low latency for critical requests, the paper deploys the proposed framework within the 3-tier computing model, namely edge, fog, and cloud tiers. The solution design considers the power consumption requirement at the edge by offloading the computational requests to the fog tier and utilizing the LoRaWAN communication technology. A prototype implementation is presented to validate the proposed framework for a university campus using e-bikes. The results show the scalability of the proposed design and the achievement of low latency for requests that require real-time decisions.

Many authors investigated fuzzy To and fuzzy Ro spaces depending IJpon the ordinary points of a set and not the fuzzy points . It is the pu£"pose of this note to SlJggest new definitions of fuzzy To and flJ zzy Ro -spaces u.s1ng Wong definition of fuzzy pOints. It will be also sho wn that these new definitions are equivalent to those introduced by Srivastava. Moreover the properties of To -ness and Ro -ness are sho wn to be both productive and hereditary and that a topologically generated fuzzy topological space .is To Or Ro if the original topologiCal . space is To or Ro, respectively.

Flow characteristics in internal combustion engine chambers of wedged and circular cross-sectional configurations were numerically investigated during intake stroke. The convex radius reduction effect on primary and secondary flow parameters was studied. Results indicated a pressure drop increase of 0.05%, and swirl number and secondary vortex intensity reductions of 14.04% and 75.57% respectively compared to circular configuration. Further optimization is needed to increase compactness without sacrificing performance.
