With the increased complexity of low-end devices in the Internet of Things (IoT), mainly due to the connectivity and interoperability requirements, the development and configuration of embedded operating systems (OSes) for such devices is not straight forward. The complexity of the communication requirements is usually mitigated by the OS, e.g., the Contiki-OS, as it already incorporates an IoT-compliant...
The Network on-Chip (NoC) is considered as an emerging technology for distributed embedded systems which is proposed as an alternative interconnection solution in Mutli-Processors System on-Chip (MPSoC). This paper proposes a graphical toll that allows researchers to generate and configure quickly their Network on-Chip in the hope to evaluate easily their contributions in no time. Unlike major existing...
It can be seen that the vision of the future networking is more focused on the things, media and services, rather than people. With the increasing importance of the Internet of Things, as well as the diversity of the objects, it is crucial to achieve the highest possible level of interoperability. This means that information exchanged needs to have the same format; in addition, data needs to be processed...
Enterprise data warehouse (EDW) with its ETL toolkit is not an adequate approach for today's business environment that is in a constant state of flux. Organizations will, in fact, improve their tactical and operational decisions by utilizing systems that can alert the organization to any critical situation in any of the business sectors and consolidate the corresponding real-time data on the spot...
As more and more Internet of Things (IoT) devices are connected to the cloud services, fog computing has emerged as a new computing model to provide analytic and intelligent services to the end users for fast response time. Among the application layer protocols used for IoT, MQTT and CoAP are two well-known lightweight protocols that run on top of TCP and UDP, respectively. MQTT supports publish/subscribe...

We propose a language definition to specify exercises with embedded variability. Using this language it is possible to process exercise specifications on a computer with the benefits of allowing an efficient retrieval and automatically generating different test versions for each of the different available platforms. These exercises, defined according to the previous specifications, should be ideally...
Industrie 4.0 components should offer flexible functionality for modern production systems. In order to achieve this flexibility, they provide functions that shall be described and implemented in an easy way. The term “functional element” is known from device profile specifications. Originally designed to be implemented in field devices, these specifications can also be used in Industrie 4.0 components...
Industrial Cyber-Physical Systems enhance physical devices with control, computing and communication abilities to provide smart solutions for industrial applications. In industrial applications, data acquisition is an important topic. Based on feedback data from sensors and equipment, industrial processes could be optimized either by experienced engineers manually or smart agents automatically. The...
This paper proposes an enhanced Interface to Network Security Functions (I2NSF) framework. To improve the whole packet throughput and manage resource of Network Security Functions (NSFs), the enhanced I2NSF framework monitors NSFs and distributes incoming packets to NSFs efficiently. Even if the legacy framework that provides security services using Software-Defined Networking (SDN) and Network Functions...
Creating school timetables is problematic in many schools due to the complexity of models that need to be solved. If schools do not have enough resources (rooms, teachers), they are forced to work double or several shifts. This paper deals with shift types and ways to write them in formats used by computers to generate timetables automatically. Even though many schools work in shifts, the constraint...
The deployment of web services in dynamic environments like cloud infrastructures offers flexible solutions to provide required resources to maintain web services availability and performance during peak demands. However, the lack of control and monitoring tools on the cloud infrastructure exposes the deployed web services to security threats. While there are security solutions that focus on web services,...
It's necessary to realize the standardization and rationalization of the knowledge representation during the milling process of Aeronautical Structural Parts. Meanwhile, It's also important to make it convenient for sharing knowledge and improve the efficiency of processing reasoning considering the intermediate status of knowledge processing. XML language is used to carry on the parametric representation...
Apply Integrated Logistics Support (ILS) to weapon equipment can efficiently improve equipment's automation and digital level. ILS needs support of various integrated support systems, which have demands for data editing. Nowadays, most of data editing software used in these systems are customized and provide a form-based editing approach, which becomes an obstacle to carry out ILS. This paper brings...
As a universal markup language, XML has been widely used in the field of Integrated Logistics Support for weapon equipment. XML Schema has become the primary choice for constraining and validating XML. Due to the textual nature of XML Schema and the complexity of XML syntax, it is difficult to understand XML Schema architecture for general developers. This paper puts forward an approach to transform...
Traditional pulsar signal processing software's object types, object parameters, task parameters, and settings of task types are fixed. Once the users want to add the object types, object parameters and task parameters, they must rechange the software interface code. This mode makes a high cost of developing the software, as well as the insufficient flexibility of using. This system, taking the independent...
The problem of modeling and operating spatiotemporal data has received a great deal of interest, due to its various applications in the real world such as GIS and sensor database. A wide range of work covering spatial data, temporal data and spatiotemporal data assumes that the data is known, accurate and complete. But in reality, information is often imprecise and imperfect. In addition, traditional...
Objective The Systems Biology Markup Language (SBML) is a popular open format for storing and exchanging computational models in biology. The definition of SBML is captured in formal specification documents. SBMLPkgSpec is a LaTeX document style intended to fill the need for a standard format for writing such specification documents. Results Specification documents for SBML Level 3 extensions (known...
With the current Web3D document format, users are forced to choose certain document formats to use, either during development with a particular tool or when it will be displayed in a browser. Only one format that can be processed by any browser at one given time. This raises the main problem of not allowing users to display a variety of objects with different formats in their browser. For this problem,...
Service-oriented computing (SOC) has been widely used by software industry for building distributed software applications that can be run in heterogeneous environments. It has also been required that these applications should be both high-quality and adaptable to market changes. However, a major problem in this type of applications is its growth; as the size and complexity of applications increase,...
