DAB (Digital Audio Broadcasting) service is becoming a cheap new media with good performance. Since 2008 Beijing Olympic Game DAB traffic information broadcasting has being severed at Beijing Radio Station by 1039 channel. Under the framework of project Metrasys (Mega Region Transport System for China) which is funded by the Ministry of German Education and Research, a TPEG based DAB traffic information broadcasting system is built at the city of Hefei by Germany-Sino experts at the beginning of 2010. In the first section of the paper the background of DAB technology was introduced, then the system diagram and its configuration was mentioned in the second section. The unique feature of Hefei DAB system was to adopt the international TPEG standard, in the third section eight classes of traffic information was defined by TPEG. In the fourth section the structure of OBU (On Board Unit) was described briefly. Section described DAB broadcast program flow at Anhui Radio Station and its performance, and finally a conclusion was given.

In a distributed quantum computation, a large quantum circuit gets sliced into sub-circuits that must be executed at the same time on a quantum computing cluster. The interactions between the sub-circuits are usually defined in terms of non-local gates that require shared entangled pairs and classical communication between different nodes. Assuming that multiple end users submit distributed quantum computing (DQC) jobs to the cluster, an execution management problem arises. This is actually a parallel job scheduling problem, in which a set of jobs of varying processing times need to be scheduled on multiple machines while trying to minimize the length of the schedule. In a previous work, we started investigating the problem considering random circuits and approximating the length of each DQC job with the number of layers of the circuit. In this work, we put forward the study by considering a more realistic model for estimating DQC job lengths and by performing evaluations with circuits of practical interest.

In this work, scalable quantum neural networks are introduced to approximate unitary evolutions through the Standard Recursive Block Basis (SRBB) and, subsequently, redesigned with a reduced number of CNOTs. This algebraic approach to the problem of unitary synthesis exploits Lie algebras and their topological features to obtain a continuous parameterization of unitary operators. First, we implemented the recursive construction of the SRBB to provide a starting tool for quickly verifying the mathematical properties needed to guarantee the original scalability scheme, already known to the literature only from a theoretical point of view. Unexpectedly, 2-qubit systems emerge as a special case outside this scheme. Furthermore, we present a method to reduce the number of CNOT gates, thus deriving a new implementable scaling scheme, which requires only one single layer and whose performance has been tested with a variety of different unitary matrices via the PennyLane library.

The reliability of non-functional contracts is crucial for many software applications. This added to the increasing attention this issue lately received in software engineering. Another development in software engineering is toward component-based systems. The interaction of both, non-functional aspects and components, is a relatively new research area, which the COMQUAD project is focusing *** component model, presented in this paper, enables the specification and runtime support of non-functional aspects in component-based systems. At the same time, a clear separation of non-functional properties and functionally motivated issues is provided. We achieve this by extending the concepts of the existing component-based systems Enterprise JavaBeans (EJB) and CORBA Components (CCM). Non-functional aspects are described orthogonally to the application structure using descriptors, and are woven into the running application by the component container acting as a contract manager. The container implicitly instantiates component specifications and connects them according to the current requests. The selection of actual implementations depends on the particular client's non-functional requirements. This technique also enables adaptation based on the specific quantitative capabilities of the running *** this paper we give a detailed description of the COMQUAD component model and the appropriate container support. We also provide a simple case study of a multimedia application for better understanding.

The work is devoted to the problem of neuro-forecasting, based on the use of a set of methods to optimize the process of building a neural network model, which will improve the quality of production of a product that meets the specified indicators. The proposed methods will predict the quality of the finished product when changing technological parameters, due to the ability of neural network models to self-study. © 2022 IEEE.

We propose a procedure for applying a teaching-learning methodology, where the student's interest is considered a relevant issue. This procedure is based on: a) resources and material available;b) specific classroom, activities;c) external classroom activities, linking the learning process with the real world;d) continuous evaluation. The full process is evaluated from both points of view: teaching and learning. The results obtained allow us verifying the appropriateness of this strategy. © 2011 IEEE.

Due to the mobility of the vehicle, the communication link between the vehicle and the edge server changes dynamically in the vehicle edge computing, leading to the increase of task completion time, transmission energy consumption, and execution cost. In order to solve the problem, this paper studies the computational handover strategy in the vehicle edge computing environment. Considering the three indicators of completion time, transmission energy consumption, and execution cost, two handover strategies based on greedy weighted of simple additivity (SAW) algorithm and greedy expectation–maximization (EM) algorithm are proposed. The experimental results show that the two handoff strategies proposed in this paper can shorten the task completion time, reduce the energy consumption of vehicle transmission, and reduce the task execution cost. © 2021, Springer Nature Singapore Pte Ltd.
