The use of Unmanned Aerial Vehicles (UAVs) in the field of Precision Agriculture (PA) is becoming more wide-spread, as the great benefits they offer are recognized by more and more farmers around the world. A UAV can fully inspect or spray arable land and crops, in just a few minutes. Farmers can use the spatial maps, photos and reports that can be produced with the help of these inspections to collect useful information in order to increase productivity and reduce costs. Drones have already been used for remote sensing in many different types of crop and environments, with great results. In this paper, we present the process adopted for monitoring remotely saffron cultivations with the use of UAVs in the Western Macedonia region of Greece, in an effort to reduce labor and costs.

This paper presents the design procedure of the digital control unit of an on-chip photovoltaic (PV) cell-level DC/AC inverter. Its main blocks are presented, along with their interconnections and timing, whereas the state diagram, based on the sinusoidal pulse width modulation (SPWM) is given, for both grid-tied and standalone operation. The proposed digital control unit is experimentally validated in a laboratory test bench, comprising four full-bridge (H-bridge) inverters in cascaded configuration. The TMS320F28379D microcontroller is employed, as it is suitable for such applications. Finally, experimental results indicate the operational characteristics of the proposed digital control scheme, being the first step for on-chip integration.

The Network-on-Chip (NoC) is physically spread over the entire chip and it should readily support communication across multiple clock domains. In NoCs, the synchronization required for sending data across clock domains should be seamlessly combined with the flow control rules that govern data transfer on NoC links. In this work, we focus on implementing virtual-channel flow control on links that connect NoC components placed across mesochronous clock domains. In mesochronous interfaces, the connected modules receive the same clock signal but the edges of the arriving clock signals exhibit an unknown phase relationship. To this end, we propose FastCross a loosely-coupled synchronization architecture for NoC links with VC flow control that simplifies hardware implementation by enabling VC buffer sharing and interface consolidation.

In this paper a study of the Cross-Correlation (CC) based, Time Difference of Arrival (TDOA) method for leak source localization on fluid-filled, metallic pipelines is presented. Several, frequency domain CC estimators (General Cross-Correlators or GCC) are considered for the implementation of the localization technique, while real leakage, vibro-acoustic dataseries, captured from a real workplace building’s tap water pipe installation are utilized within the current analysis. Certain metrics like the rate of acceptable leak positioning results against all localization estimation experiments conducted, as well as the Relative Localization Error (LRE) of the accepted estimations are calculated and illustrated in order to shed light on the performance characteristics of the TDOA approach (in general and also per adopted CC estimator). The above study is pursued within the framework of project ESTHISIS, with end target the development of a smart sensor system for leakage detection in pipes carrying hydrocarbon products.

This work, presents the design and the implementation of a mobile robot that can cover given workspaces. The motion commands have been produced by a chaotic system which gives high "randomness" to its behavior. For the implementation of the robot a microcontroller has been used (Arduino Uno). Moreover, the obstacle avoidance has been achieved by using an ultrasonic sensor, which enables the tracking and avoidance of placed obstacles. As a result, the motion trajectory becomes smoother. The robot’s behavior has been studied in scenarios with different starting positions showing promising results.

Memristors are novel and hopeful electronic memory components. They might be potential substitution of the CMOS elements. Owing to their nano dimensions, low power consumption and memorizing properties, the memristors could be applied in artificial neural networks, memory matrices, programmable analog and digital schemes and other electronic circuits. In this work, a modified and simple, fast operating transition metal oxide-based memristor model is proposed. Its respective LTSPICE library model is created and effectively analyzed in simple memristor-based analog filters. The model’s operation is in agreement with the main patterns of the memristive elements. Its correct functioning and applicability in memristor-based electronic circuits is confirmed.

Internet of Things devices are commonly utilized in smart homes to provide smart services such as lighting, entertainment, and easy access, but they are also employed to warn occupants in the event of an emergency. Due to the computationally intensive nature of existing Neural Network implementations, data must be transmitted to the cloud for analysis to produce intelligent machines. TinyML is a promising approach that the scientific community has proposed as a method of constructing autonomous and secure devices that can collect, analyze, and output data without requiring it to be transferred to remote entities. This work presents a TinyML-based system for detecting hazardous gas leaks. The system may be trained to detect irregularities and notify occupants using BLE technology via a message sent to their smartphones, as well as through an integrated screen. Two different test cases are presented and evaluated via experiments. For the smoke detection test case the system achieved an F1-Score of 0.77, whereas for the ammonia test case the evaluation metric of F1-Score is 0.70.

High-Functioning Autism Detection in Adults is significantly difficult compared with early Autism Spectrum Disorder (ASD) diagnosis with severe symptoms. ASD diagnosis is usually achieved by behavioural instruments relying on subjective rather on objective criteria, whereas advances in research indicate cutting -edge methods for early assessment, such as eye-tracking technology, machine learning, Internet of Things (IoT), and other assessment tools. This study suggests the detection of ASD in high-functioning adults with the contribution of Transfer Learning. Decision Trees, Logistic Regression and Transfer Learning were applied on a dataset consisting of high-functioning ASD adults and controls, who looked for information within web pages. A high classification accuracy was achieved regarding a Browse (80.50%) and a Search (81%) task showing that our method could be considered a promising tool regarding automatic ASD detection. Limitations and suggestions for future research are also included.

In the present work, a general methodology is introduced for the determination of the writer of a given document, provided that texts of the same hand are available. The approach is successfully applied to an unsigned document that has been spotted in the warehouses of Greek Army History Directorate and led, for the first time, to the conclusion that it has been written by the great Greek Politician Eleftherios Venizelos. The content of the paper is important from the historical point of view.

The most widely-used model of the excitation and propagation of impulse (action potential) in nerve membranes is the Hodgkin-Huxley system. In this paper we consider its simplification - a coupled FitzHugh Nagumo model. We shall study its dynamics from the point of view of local activity theory and we shall define the edge of chaos region in which complex behavior appears. Simulations show that oscillatory patterns, chaotic patterns, or divergent patterns may emerge if the selected cell parameters are located in locally-active domains but near the edge of chaos.
