This paper presents a real-time, low-cost, wireless, AC and DC monitoring system based on an ATmega328P-PU microcontroller. The proposed system is composed by different client nodes, which have the task to measure the main electrical quantities involved in the system, and a server node that collects the data and send them to a display device. The system is well suited for a good accuracy monitoring...
Multilevel system architecture of energy efficiency management in the region is developed in this work. The architecture model consists of three levels, namely, level of data collection and management of executive mechanisms, level of control and management of technological process, and level of operator control and formation of administrative decisions. Hardware and software of each hierarchical...
For environmental impact analysis remote hosting of instrumentation system consisting of sensors provides a seamless, authentic method of establishing communication. These methods provide the on the spot parametric measures for prediction analysis and disaster management. Though the drones provide visual imagery of the impacted area, they are faced with payload and power limitations when sensors are...
The challenges to deal with to design a WSN node which can be used in safety-relevant application are, to the present day, still to be completely investigated and solved. Nevertheless, a prototype implementation is presented in this paper, with an emphasis on the chosen hardware architecture and components, highlighting the limitations imposed by specific choices. Furthermore, an example application...
Lightweight cryptography aims to address the security demands in resource-constrained hardware and software environments, such as the Internet of Things (IoT). These constraints severely limit solutions offered by conventional cryptographic primitives, which turn too expensive to achieve. In this paper, a lightweight pseudorandom number generator that fits the IoT demands is presented. It has a good...
With the improvement in standard of living of human beings, better home/office environment is required. Nowadays, intelligent home designs are becoming a trend in which intelligence can be built-in to provide improved user comfort at an incremental cost. However, many of the mature systems do not care about the energy savings. This paper presents a smart home solution with energy conservation in mind...
The advent of the Internet of Things (IoT) has proliferated the use of connected sensors to observe and control the world around us. Wireless Sensor Networks (WSN) are becoming ubiquitous tools that monitor their surroundings and also oftentimes provide actuation to affect the state of their environment. One of the key application domains for real-time monitoring and control is the freight railroad...
Generally falls may occur from moving or resting postures. This may include slipping from bed and fall from a sitting, or from running or walking. The pre-fall is a non-equilibrium state of human position that may lead to serious injuries, and may negatively impact the quality life condition, particularly for elders. Physical disabilities resulting from the fall incidences may lead to high costs involved...
Many industrial application could benefit from the use of wireless sensor networks technology in safety critical context. This paper analyses the existing platforms to determine if they are suitable for a safety related application, analyses the possible modification to fulfill the requirements and propose an architecture that combines costs, performances and reliability.
A designed set of practices for a general course of Automotive Electronics is presented. The practices have been designed using the ‘mbed’ environment with the LPC1768 microcontroller. These practices aim to address the interaction of a system based on microcontroller and a real time operating system, with sensors and actuators, including buses commonly used in vehicles and OBD-II diagnostic systems.
This study looks at the need for a device that monitors upper extremity movements. The device needs to be able to predict gestures on-board to provide immediate feedback. Linear Discriminate Analysis and Support Vector Machine Light and Support Vector Machine Multiclass libraries were implemented on an Atmel embedded system to investigate the limitations. For the Support Vector Machine Light implementation...

As machines in most industries continue to grow in complexity, user interfaces play an increasingly important role in allowing operators to naturally interact with such machines. In this paper, we present a versatile approach that can enable operators to interact with a variety of machines using smart mobile devices. A low-cost, embedded system-based setup and an easy-to-implement communication method...
Tracking the position and the orientation of human limbs to reconstruct postures and actions is becoming a crucial need in several application domains, including medicine, rehabilitation, sport, and games. However, most available solutions are expensive, imprecise, or require an instrumentation of the environment. This paper presents a low-cost tracking system based on a set of wearable inertial measurement...

These two factors are crucial for the plant growth inside a polyhouse. The prototype is designed by using AT89S52 microcontroller and tested successfully. The system can provide ideal temperature and humidity...
Depending on the way the mentally challenged children learn things, they are categorized into groups such as visual learners, auditory learners, reading /writing preference learners, kinesthetic learners. This paper integrates all the learning abilities of mentally challenged children and proposes an Interactive Number Learning System. It helps mentally challenged children to learn the basic numbers...
In this work we address the management of a platoon of vehicles passing an intersection. In such a situation we have to decide under which conditions the platoon can pass the intersection in its entirety while avoiding collisions. If this cannot be assured, the platoon should be stopped at the intersection line or possibly split. For this purpose a decision about the vehicle from which the platoon...
Three-axis accelerometers have been widely used not only in motion sensing but also in tilting sensing nowadays. The tilting angle conversions from 3D acceleration data involves with complicated mathematic calculations such as multiplication, division, square-root and trigonometric functions. Indeed, the conversion can be done by only using simple addition, subtraction, and shifting operations through...
The project aims at developing a prototype boat that is capable of autonomously sailing and navigating its way through obstacles present around it. Apart from moving on a pre defined path the boat can intelligently avoid obstacles in the path through its ability of decision making using fuzzy logic. Calculations of fuzzy logic as well as deciding inputs for the path direction to be sent to the micro...
