Application Specific

Continuing advances in the fields of very-large-scale integration (VLSI), ultralarge-scale integration (ULSI), and gigascale integration (GSI), leading to the continuing development of smaller and smaller devices, have continually challenged the fields of materials, processes, and circuit designs. The existing metallization schemes for ohmic contacts, gate metal, and interconnections are inadequate for the ULSI and GSI era. An added concern is the reliability of aluminum and its alloys as the current carrier. Also, the higher resistivity of Al and its use in two-dimensional networks have been considered inadequate, since they lead to unacceptably high values of the so-called interconnection delay or RC delay, especially in microprocessors and application-specific integrated circuits (ICs). Here, R refers to the resistance of the interconnection and C to the total capacitance associated with the interlayer dielectric. For the fastest devices currently available and faster ones of the future, the RC delay must be reduced to such a level that the contribution of RC to switching delays (access time) becomes a small fraction of the total, which is a sum of the inherent device delay associated with the semiconductor, the device geometry and type, and the RC delay.

New Generation

Transforming basic multi-disciplinary research into applied research in the area of a new generation of networks, sensors, cyber-physical, and edge-cloud systems used for cyber space is a difficult task. However, moving even a step forward by providing advanced field and testing facilities for ground-air demonstrations for appearing Aviation 4.0 scenarios is a real challenge. In our opinion, such a rapid and dynamic process should be powered by many research and infrastructure projects. New development strategies are needed in the upcoming future to link emerging trends in information and communications technologies together with increased competitiveness and users expectations from fully autonomous drones, robots, cars, etc. This paper aims to share our early experiences in setting and providing distributed testbeds to cross different hardware, software, and cyber-physical components and pave the way for air-ground demonstrations of the new emerging IT paradigm – digital continuum. We also share our vision of implementing virtual and digital spaces at a large scale by the gradual transition towards higher levels of cyber-physical systems automation and autonomy. Finally, we promote dynamic, data-driven, service-oriented approaches and network-centric platforms for a new generation of air and ground control systems which will be validated in real conditions established thanks to our new airfield-based laboratories used in many ongoing and future R&D projects.

Implementation Tool

Docker engine is an extremely powerful tool for PaaS platform of cloud computing. It gives benefits for large-scale of internet services. Web service is basic service for everyone who requires to access internet that web infrastructure must has scalability with load-balance web server called reverse proxy. The key answers for a large-scale web must have multiple web servers working together with high speed bandwidth. Moreover, multiple clusters can find in the same data center there are required to assign priority and quality of each cluster service. We investigate load-balance assign link aggregation with network QoS by using pipework script and traffic control tool in frontend reverse proxy server on each cluster. Our research evaluates scenario of network QoS ratios which include 50/50, 60/40, 70/30 and 80/20. We compare network bandwidth between both web reverse proxy clusters. The results present our designed and implementation tool not only can control network QoS on each web reverse proxy cluster in all load-balance link aggregation modes which include round-robin, XOR and ALB but also those of clusters can access multiple network interface. In experiment, average network bandwidths in all QoS cases are around 200 MB per second for link aggregation of 2 gigabit interface.

And Control

Since the advent of large-scale commercial aviation in the mid 1940s, a system of routes has been developed between airports serving the major conurbations of the world. To prevent collision between aircraft using these routes and off-route traffic, protection is provided to the routes and to the vicinity of airports by means of controlled airspace, airways (AWYS), control areas (CTAS) and control zones (CTRS). Zones commence at ground level and the base an area is at a defined altitude. Inside this controlled airspace certain rules apply which are more stringent than those applied outside, and all movements are subject to Air Traffic Control (ATC).

And Control

Formal argument suggests that command, communication and control systems can remain stable in the sense of the Data Rate Theorem that mandates the minimum rate of control information required to stabilize inherently unstable 'plants', but may nonetheless, under fog-of-war demands, collapse into dysfunctional modes at variance with their fundamental mission. We apply the theory to autonomous ground vehicles under intelligent traffic control in which swarms of interacting, self-driving devices are inherently unstable as a consequence of the basic irregularity of the road network. It appears that such 'V2V/V2I' systems will experience large-scale failures analogous to the vast propagating fronts of power network blackouts, and possibly less benign, but more subtle patterns of `psychopathology' at various scales.

Alerting System

Vehicle use is expanding dramatically, which means that vehicle-related risks are increasing as well. High speeds, driving while inebriated, distracted driving, overstress, and electronic gadgets are the leading causes of accidents. This work is about an accident detection system that occurs as a result of carelessness on the part of the driver. This introduces an accident alerting system, which notifies the driver of the vehicle. When an individual seems unable to control his or her car, an accident happens. This technology will transmit information to the registered mobile number once the car is involved in an accident. Our lives have been made easier by the rapid advancement of technology and infrastructure. The advancement of technology has also increased transportation risks, and road accidents are becoming more common, resulting in significant loss of life and property due to inadequate emergency services. Despite the presence of so many contemporary equipment in the field of vehicle design, large-scale road lane design and heavy traffic control mishaps do occur. Accidents are posing a greater threat to human life, with traffic accidents being the most common. Many people die as a result of medical services and family members failing to receive accident information in a timely manner. Any type of mishap that is detected is automatically transmitted to the relevant destination as an alert. When a vehicle's accident detecting equipment recognizes an accident, it sends SMS/ messages to the driver's family, police station, ambulance, and nearby hospital's pre-installed numbers. This is an embedded system. It may be used to track and retrieve the exact location of any car that has been involved in an accident. Using the Global Positioning System (GPS) and sensors, we were able to avoid an accident.
