At present, with the advent of ICTs, e-government systems are undergoing an important evolution which consists of providing fluent and simple services to their citizens. One of the egovernment implementations is to create a form of interoperability relationship between different services at different levels: national level, state or district government level. However, government sectors face many challenges in using e-government services and adapting them to the needs of citizens as data and applications continue to increase, as well as migration challenges of integration and interoperability of these data. Therefore, it is necessary to find a solution to overcome these challenges. Complex Event Processing (CEP) has emerged as a new paradigm for event-driven architecture (EDA) that can ensure interoperability and bring efficiency to an organization. At the same time, every government strives to become smart and increasingly interoperable and aims to help build a smart city through the use of a Business Intelligence (BI) solution and adopting new technologies. This paper proposes a hybrid approach for e-government interoperability and data integration using a combination of Datawarehouse and EDA-based approach. The purpose of this combination is to interconnect the data and applications of e-Government that are separated and isolated in order to communicate with each other at different government levels.

The persistent problem circulating around various university canteens has always been about high crowd density during lunch hours. To efficiently tackle this issue, a platform called “vCanteen” has been developed that integrates an online food ordering system, a virtual queuing system, together with a machine learning-based crowd estimation system. vCanteen aims at reducing queuing time when ordering food, and allowing users to know the estimated crowd density in a university canteen in real-time. The crowd estimation system has been developed using a multi-column convolutional neural network (MCNN). This paper discusses the vCanteen prototype that was developed and tested at the canteen in the Faculty of Engineering, Chulalongkorn University, Thailand. The description of the crowd estimation system is provided in details including error evaluation and lessons learned.

This project developed an Android application to provide users with options on which public transportation routes to use in Juarez City. To make this possible, we went to request information from the various lines of the city to the Transportation Office of the State Government. Subsequently, various tools were developed to support the process of capturing routes, editing, and obtaining intersections between them. The solution consisted of a client-server architecture, where the client is an application for mobile devices, which is used by users, and the server is the application responsible for returning possible routes to customers. We achieve this with the help of Quadtree algorithms to partition the space and thus obtain coordinates of routes near the origin and destination. It results in an efficient manner using Dijkstra for the search of roads using the routes near the beginning and the destination. Finally, to validate its usefulness, a survey was conducted to UACJ students, which consisted of three sections, the first on personal data of the respondent, the second on the use of public transport and the third about the Android application.

In this paper, a new scheme for dynamic relocation in free floating car sharing systems is proposed. First, a heuristic approach is presented for designing a car relocation plan which achieves a better balance between supply and demand in such a system within strict time limits. As being heuristic, the algorithm is fast, further aiding in maintaining fast responsiveness in dynamic scenarios. Furthermore, an on-fly-correction of the original relocation plan is also presented for dealing with changes in car distribution happening in the system due to its concurrent use by the users. Thus, the relocation plan is still effective even in the case that the predictions of future user movements are not accurate.

Advanced Traveller Information Systems (ATIS) have seen a steady increase in popularity in the last decades among urban users. By providing travellers with relevant information, these systems have the ability to considerably improve traffic flow, but are limited by their penetration rate among the city’s population. In this work we put forward HERMES1, a tool to facilitate the evaluation of road networks through simulation with different ATIS and with different levels of information percolation among users. The usefulness of such a tool stems from the quantification of the extent to which an ATIS can improve total travel time and road utilisation by means of experimenting with simulation scenarios. This tool operates at a mesoscopic level, in which single users may be represented independently from each other, nonetheless are rather considered to operate at their macroscopic interactions with the network. We also illustrate example use cases for the tool on the motorway network between the Portuguese cities of Lisbon and Porto.

Swarm unmanned aerial vehicles (UAVs) are critical to a number of smart city applications, such as distributed sensing and disaster relief. Connected UAVs often operate in complex environments where the communication channels suffer fading loss. Achieving full spatial diversity is important for reliable communication, but cannot be guaranteed at any given time. Here, we show that delay tolerant transmission via caching can enable full diversity. To achieve this, we improve the decode-and-forward cooperative relaying scheme, where the number of successful relay UAVs increases with each additional cooperation stage. We demonstrate a trade-off between the achievable bit error rate and the necessary delay via caching. The results show that a small delay enabled by UAV caching can enable full diversity at SNR levels 10–$;100 times$ lower in most mobile swarm cases. The proposed protocol can dynamically trade-off transmission reliability with caching capacity and enable reliable UAV swarm coordination in complex environments.

South Africa has grown from 34% electrification in 1991 to about 84.7% electrification presently, but with least access to electricity in rural areas. The lower rate of electrification in rural areas than urban areas has made dwellers in rural unelectrified areas to be challenged economically, socially, educationally, health-wise, etc. The aging, unclean, nonrenewable and constrained traditional grid has necessitated to think out of the box for universal electricity access in the nation through renewable energy sources (RES) such as solar, wind, biomass, and hydro for rural electrification. Therefore, a RES-powered microgrid is designed for rural Jozini municipality with 26.3% electricity access. This proposed Jozini microgrid was found to have a Levelised Cost of Electricity (LCOE) of R0.384/kWh, which is about one-third of grid LCOE in South Africa. Also, the proposed Jozini microgrid has 0 kg/kWh CO2 emission compared to 0.99 kg/kWh CO2 emission from the traditional national grid.

The transformation of cities into smart cities is one of the demanded topics in city planning, following the long-term trend of digitization. While installing a smart device seems relatively easy from a technical point of view, the question of transformation needs a knowledge-based perspective. Which parameters should be measured, how could a data infrastructure be introduced, how is it possible to apply gathered data of different devices for the deduction of knowledge and how can overarching smart city concepts and projects be implemented? The paper addresses these questions for a scenario in the field of smart environment. A smart city transformation model is introduced and the Green KM Cube, as part of green knowledge management, is applied as a method for detailing the phases through knowledge management dimensions to facilitate planning and decision support. The result is the basis of the requirements analysis of the transformation model.
