Systems whose functionality and services span over multiple, interconnected application domains have become known as cyber-physical system (CPS) and currently receive much attention in research and practice. So far, CPS still come with a variety of development-process-related and technical challenges. These challenges include the interaction between the different domain-specific systems and possible...
Many carpool and ride-sharing solutions have been proposed and even developed in the previous decades, but rarely have they been able to attain a global user base, at least not up until recently. That was mostly because many of them were not initially designed as scalable, leaving their users with a sub-par user experiences as their user base grew, and often their mobile or desktop client reach was...
Autonomous Ground Vehicles (AGV) require diverse sensor systems to support the navigation and sense-and-avoid tasks. Two of these systems are discussed in the paper: dual camera-based computer vision (CV) and laser-based detection and ranging (LIDAR). Reliable operation of these optical systems is critical to safety since potential faults or failures could result in mishaps leading to loss of life...
The main objective of this paper is proposition simple, easy to implementation and low cost solution dedicated for parking lots reservation. The presented application uses Unstructured Supplementary Service Data (USSD) as an communication channel between driver and parking system. USSD communication proposed in this paper is more efficient and comfortable for the end user in comparison with SMS used...
This paper describes a system for recognition of objects in traffic scene from multiple moving vehicles. The system is based on query and image processing. It allows image recognition along with a spatial relation. A user or a machine makes a query in which description of searched objects are defined. Then the query is sent to vehicles in order to process in real-time. If any vehicle recognizes object...
In this paper the capacitated vehicle routing problem with time windows is tackled with a beam-search based approximate algorithm. An instance of this problem is defined by a set of customers and a fleet of identical vehicles. A time window is associated with each customer and a maximum capacity characterizes a vehicle. The aim is then to serve all the customers by minimizing the number of vehicles...
The paper presents a set of mobile applications aiding the visually impaired in using the public transport. A user equipped with a modern smartphone with mobile data transmission and positioning capabilities can access location related context information. Keeping up the connection with dedicated system servers gives the user access to additional services, e.g. enables the use of passenger information...
Location based services (LBS) are considered very relevant for the users of mobile networks. All local events and facts related to area nearby seem to be more important that others which happen in remote places. Localization data is used in all types of services: weather, traffic, tourist info, etc. One of its most important (and regulated by law) applications is providing persons location in case...
One of the more important stages in the development of wireless networks was developing protocols, procedures and systems providing packet data transmission. Packet data transmission enables sending sets of measurement data and other information over long distances, and thus integrating with other available networks, for example the Internet. The aim of this article is to demonstrate the implementation...
The Dial-a-Ride Problem (DARP) models an operation research problem related to the on demand transport. This paper introduces one of the fundamental features of this type of transport: the robustness. This paper solves the Dial-a-Ride Problem by integrating a measure of insertion capacity called Insertability. The technique used is a greedy insertion algorithm based on time constraint propagation...
