This study is about the disastrous flooding of an Indian metropolitan area of Chennai when the rain had nearly broken the record of 100-years with 374 mm rain falling on December 1, 2015, virtually breaking the November monthly average of 407.4 mm in a day. This city with a population of approximately 6.7 million people came to a standstill. Astonishingly, one of the biggest software development hubs...
A real-time simulator is an essential tool for swiftly designing and verifying embedded time-sensitive and/or real-time applications in both academia and industry. An FPGA-based wireless extensible hardware-in-the-loop (WEX-HIL) real-time simulator was developed for designing subsystems of an electrical vehicle (EV). The WEX-HIL platform is capable of providing a design and test environment of virtual...
Traditional STEM education models in electrical engineering and computer science rely on structured classes, laboratories, and textbooks to transfer key concepts. Even though this process meets most of the ABET objectives, it does not respond well to current workforce needs that require widely accessible programs that will provide a large pool of graduates with STEM backgrounds, analytical and programming...
Hardware-in-the-loop (HIL) and fault injection testing are widely used in automotive industry to validate hardware and software architectures as best practice and in fulfillment with international functional safety standards. Time and economical investments can constitute an obstacle to the development of effective testing systems, especially for small and medium automotive industries. This paper...
Hydro-Québec operates 63 hydroelectric power plants and owns 668 dams, as well as 98 control structures. In order to ensure their safety and proper operation, Hydro-Québec's Research Institute (IREQ) develops robotic technologies that can perform diagnosis and intervention tasks underwater. Over the last 20 years, several generations of underwater Remotely Operated Vehicles (ROVs) have been developed...
Software is eating the world. But how will we write all the programs to control everything from sensors to data centers? Program synthesis provides an answer. It increases the productivity of programmers by enabling them to capture their insights in a variety of forms, not just in standard code. In this tutorial, we focus on some challenges in programming networks, and we show how program synthesis...
Personal assistant agents have various abilities to support the user's tasks in the background. They are expected to be run on laptops, portable devices and even on IoT devices. Since their abilities are sometimes restricted by their running environments and hardware, is not always easy for single personal assistance agent to accomplish all the tasks. This paper presents our design and implementation...
In 1986, this author presented a paper at a conference, giving a sampling of computer and network security issues, and the tools of the day to address them. The purpose of this current paper is to revisit the topic of computer and network security, and see what changes, especially in types of attacks, have been brought about in 30 years. This paper starts by presenting a review of the state of computer...
The functional diagnosis expert system based on knowledge base in the form of neuro-fuzzy network was proposed in this paper. Current values of diagnostic parameters are measured by sensors. The hybrid expert diagnostic system with neuro-fuzzy network knowledge base supports decisions in the situation when the diagnosis algorithm is not known and is formed from the initial data in the form of production...
In this work we present our work towards the development of an ultra-fast power-based interrogation platform for its use with photonic bandgap (PBG) sensing structures. These structures are designed to have a characteristic spectral feature (a PBG edge), which will be shifted when a change of the refractive index is produced on their upper cladding. The interrogation is simply made using a filtered...
This paper presents the different stages of development of flight controller for unmanned aerial vehicle (UAV) with autonomously flying capability. The main purpose of flight controller is to perform a petrol function between given GPS coordinates while maintaining a specified altitude for an assigned time and then return to its launching position without any human interaction. At first a simulated...
This paper explored the opportunities for using unmanned surface vehicles for anti-submarine warfare. Areas of the problem where such vehicles are likely to contribute value are discussed, along with an approach for developing and utilizing such vehicles.
The development process of an intelligent autonomous underwater vehicle (AUV) is based on experiential knowledge leading to uncertainty in the software development for the intelligent AUV control. In this work we suggest an expert system to implement the AUV control software because expert systems handle uncertainty during the development process better than conventional, procedural programming languages...
The main focus of this paper is to present control and automation aspects of the remotely operated CRD100 seafloor drill. The CRD100 is a fourth generation, state-of-the-art robotic seafloor drill that is directly deployed onto the seabed. It is designed to drill, case, core, and collect geotechnical sampling data to a depth of 65m below the seabed at 3000m beneath the water surface. The system must...
Data acquisition systems used as Internet of Things (IoT) devices are generally developed for applications such as renewable energy, vehicles, or biological data collection. Methodology adapted from IoT can be used in numerous applications including sensors for underwater vehicles. Autonomous Underwater Vehicles (AUV) have become more prevalent for military use. Coincidentally, modular sensor attachments...
Due to the positive effects concerning comfort, economic and ecologic reasons, building automation systems are increasingly integrated into nowadays buildings. Furthermore the investigations in cyber physical systems and the internet of things blur the line between the originally separate systems and lead to smart buildings cooperatively operated together with non-building automation systems. The...
Modern smartphones integrate multiple functionalities into a single device: they can establish peer-to-peer wireless links, they can sense the environment through several embedded sensors, they are provided with a multi-core CPU. Hence, they can play a crucial role on emergency scenarios, where there is need of acquiring data from the environment, processing, and quickly conveying them to the people...
When dealing with security concerns in the use of network infrastructures a good balance between security concerns and the right to privacy should be maintained. This is very important in scientific networks, because they were created with an open and decentralized philosophy, in favor of the transmission of knowledge, when security was not a essential topic. Although private and scientific information...
The industrial, scientific and medical band is widely used by different wireless systems. The identification of other wireless technologies in the common environment is one of the keys for correct system coexistence. In this work, a sensing platform for the detection of IEEE 802.11g and IEEE 802.15.4 primary signals in the 2.4 GHz band is proposed. The sensing platform makes use of a combined scheme...
Natural gait consists of synchronous and rhythmic patterns for both the lower and upper limb. People with hemiplegia can experience reduced arm swing, which can negatively impact the quality of gait. Wearable and wireless sensors, such as through a smartphone, have demonstrated the ability to quantify various features of gait. With a software application the smartphone (iPhone) can function as a wireless...
