Engineering Web technologies for embedded applications

The founder of Agranat Systems examines the design issues involved in engineering effective Web technologies for embedded systems. Small embedded TCP/IP stacks and Web server software now make it possible to manufacture reliable, inexpensive Web-enabled devices across many industries and markets. Embedded systems require Web servers that are designed to minimize memory footprint and avoid interference with mission-critical and real-time applications. To guarantee a reliable user interface with minimal impact on system performance, the server software should utilize the latest HTTP 1.1 standards from the Internet Engineering Task Force. It won't be long before intelligent devices worldwide will be nodes on a network and managed from Web browsers     

Evolving technologies for new Internet applications

Tactile interfaces: technologies,applications and challenges

Tactile interfaces are used to communicate information through the sense of touch, which is an area of growing interest in the research community. Potential applications include virtual training for surgeons, remotely touching materials via the Internet, automotive industry, active interfaces for blind persons, and sensory substitution devices.     

Containerization technologies: taxonomies,applications and challenges

Modern scientific research challenges require new technologies, integrated tools, reusable and complex experiments in distributed computing infrastructures. But above all, computing power for efficient data processing and analyzing. Containers technologies have emerged as a new paradigm to address such intensive scientific applications problems. Their easy deployment in a reasonable amount of time and the few required computational resource make them more suitable. Containers are considered light virtualization solutions. They enable performance isolation and flexible deployment of complex, parallel, and high-performance systems. Moreover, they gained popularity to modernize and migrate scientific applications in computing infrastructure management. Additionally, they reduce computational time processing. In this paper, we first give an overview of virtualization and containerization technologies. We discuss the taxonomies of containerization technologies of the literature, and then we provide a new one that covers and completes those proposed in the literature. We identify the most important application domains of containerization and their technological progress. Furthermore, we discuss the performance metrics used in most containerization techniques. Finally, we point out research gaps in the related aspects of containerization technology that require more research.

     

Industrial applications of agent technologies

This paper is aimed at summarizing the current state-of-the-art in the development of agent-based solutions in three areas connected with industrial production, namely in holonic control, production management and virtual enterprises. This paper shows how the results in these three sub-areas are converging and discusses how the agent-oriented technologies could provide a good background for developing a unifying approach. Two industrial applications of agent-based systems are described in some detail. The paper also presents both the positive and negative aspects of applying agent-based technologies in industry.

Embedded devices for supply chain applications: Towards hardware integration of disparate technologies

The emergence of the RFID technology and its application to supply chain processes has in particular led to the creation of such standards as the EPCglobal’s model of supply networks as a tool for materializing intra- and inter-enterprise visibility of resources and products, collaboration and integration. Among other critical uses, RFID has been deployed by supply networks to improve asset utilization, effectively combat counterfeiting, and advance targeted product recalls. However, new affordable and deployable technologies and microsensors have recently appeared and keep maturing. This paper discusses the needs and the possibilities that exist for leveraging these technologies and sensors with RFID to guarantee continuous and seamless visibility of all assets (fixed and mobile resources and field personnel) of smart enterprises, thereby expanding and complementing the roles of RFID. It examines the design challenges for the integration of these technologies for advanced logistics operations at the level of product classes or their instances. It then outlines our development of an embedded microsystem that combines RFID, GPRS, GPS and environmental sensors for applications in logistics. The prototyped microsystem demonstrated the feasibility of the multi-sensor integration paradigm that the paper proposes.     

Remote rendering solutions using web technologies

Remote rendering is a well-known solution to the issue of running high-performance applications requiring complex visualizations on less capable hardware/software platforms or when client access to the data source for visualization is undesired or prohibitive in terms of required bandwidth. Visualizing the output of these remote rendering applications is typically achieved through native applications or, when considering a browser environment, through plug-ins. In this paper, several solutions are presented that enable deployment of these applications on standard web browsers, even those from the pre-HTML5 era. The focus in this paper is on two specific use case scenarios, taking into account that the proposed solutions are generic enough to be applied to a range of similar applications. The technologies presented cover the entire range of sub-processes contained in a complete remote rendering solution, such as the establishment of interaction feedback channels and delivery of images as part of the rendering pipeline. Depending on factors such as application requirements, developer preferences, feature availability in the web browser or raw performance figures, a custom solution can be composed from the options discussed in this paper. This is illustrated by applying them to the two aforementioned use cases, each with specific requirements and challenges, and benchmarking these example setups in terms of performance. A comparison of advantages and disadvantages is presented to guide developers in applying the technologies under real-life conditions.
