Optimal Interpolation for infrared satellite data
Thermal infrared remote sensing measurements are blinded to surface emissions under cloudiness because infrared sensors cannot penetrate thick cloud layers. Therefore, surface and atmospheric parameters can be retrieved only in clear sky conditions giving origin to spatial fields flagged with missing pieces of information. Motivated by this we present a methodology to retrieve missing values of some interesting geophysical variables retrieved from spatially scattered infrared satellite observations in order to yield level 3 (L3), regularly gridded, data. The technique is based on a 2-Dimensional (2D) Optimal Interpolation (OI) scheme. The goodness of the approach has been tested on 15-min temporal resolution Spinning Enhanced Visible and Infrared Imager (SEVIRI) emissivity and surface temperature (ST) products over South Italy (land and sea), on Infrared Atmospheric Sounding Interferometer (IASI) atmospheric ammonia (NH3) concentration over North Italy and carbon monoxide (CO), sulfur dioxide (SO2) and NH3 concentrations over China. Sea surface temperature (SST) retrievals have been compared with gridded data from MODIS (Moderate-resolution Imaging Spectroradiometer) observations. For gases concentration, we have considered data from 3 different emission inventories, that is, Emissions Database for Global Atmospheric Research v3.4.2 (EDGARv3.4.2), the Regional Emission inventory in ASiav3.1 (REASv3.1) and MarcoPolov0.1, plus an independent study.

Cybersecurity Standards
Cybersecurity standards (also styled cyber security standards) are techniques generally set forth in published materials that attempt to protect the cyber environment of a user or organization. This environment includes users themselves, networks, devices, all software, processes, information in storage or transit, applications, services, and systems that can be connected directly or indirectly to networks. The principal objective is to reduce the risks, including prevention or mitigation of cyber-attacks. These published materials consist of collections of tools, policies, security concepts, security safeguards, guidelines, risk management approaches, actions, training, best practices, assurance and technologies.

Deep Reinforcement Learning Approaches for Smart Manufacturing
AI and, in particular, the Deep Reinforcement Learning (DRL) algorithms, which are a perfect response to the unpredictability and volatility of modern demand, are studied in detail. Through the introduction of RL concepts and the development of those with ANNs towards DRL, the potential and variety of these kinds of algorithms are highlighted. Moreover, because these algorithms are data based, their modification to meet the requirements of industry operations is also included. Digital twins are a technology that is increasingly important in I.40 and I.5.0, which seems to be crucial to the development of smart manufacturing.

HAR in Smart Homes
Human Activity Recognition (HAR) consists in monitoring and analyzing the behavior of one or more persons in order to deduce their activity. In a smart home context, the HAR consists in monitoring daily activities of the residents, based on a network of IoT devices. Owing to this monitoring, a smart home can offer personalized home assistance services to improve quality of life, autonomy and health of their residents, especially for elderly and dependent people.

Robotic-Systems for Improving Upper-Limb Spasticity
Spasticity is a motor disorder that causes stiffness or tightness of the muscles and can interfere with normal movement, speech, and gait. Traditionally, the spasticity assessment is carried out by clinicians using standardized procedures for objective evaluation. However, these procedures are manually performed and, thereby, they could be influenced by the clinician’s subjectivity or expertise. The automation of such traditional methods for spasticity evaluation is an interesting and emerging field in neurorehabilitation. One of the most promising approaches is the use of robot-aided systems.

Robotic Platform for Horticulture
The modern level of development of infocommunication and computer technologies, microprocessor technology and equipment, communication and positioning makes possible the development and practical application of automated and robotic technologies and technical means to improve the efficiency of agricultural production. Currently, intensive horticulture is becoming increasingly widespread due to rapid fruiting and high yield rates. At the same time, the process of harvesting apples in intensive horticulture is the most time-consuming, and harvesting is carried out mainly by a team of pickers. In the production process of cultivating fruit crops, this is an important final stage which requires the development of automated devices and robotic platforms with a control system capable of offline harvesting.

Fyne
Fyne is a free and open-source cross-platform widget toolkit for creating graphical user interfaces (GUIs) across desktop and mobile platforms. Fyne uses OpenGL to provide cross-platform graphics. It is inspired by the principles of Material Design to create applications that look and behave consistently across all platforms. It is licensed under the terms of the 3-clause BSD License, supporting the creation of free and proprietary applications. In December 2019 Fyne became the most popular GUI toolkit for Go, by GitHub star count and in early February 2020 it was trending as #1 project in GitHub trending ranks.

Forensic Arts
Forensic art is any art used in law enforcement or legal proceedings. Forensic art is used to assist law enforcement with the visual aspects of a case, often using witness descriptions and video footage. It is a highly specialized field that covers a wide range of artistic skills, such as composite drawing, crime scene sketching, image modification and identification, courtroom drawings, demonstrative evidence, and postmortem and facial approximation aids. It is rare for a forensic artist to specialize in more than one of these skills. Many forensic artists do the job as a collateral duty to their "regular" job in law enforcement, such as police officer, crime scene tech, etc. Such forensic artists perform their work while on a fixed salary and are not additionally compensated for artistic duties. There are few full-time forensic artist jobs available. Most full-time artists work in large cities, or in state or federal agencies. "Freelancing" in forensic art is a difficult career path, as ties to law enforcement are a necessary part of the job, and agencies have limited budgets to pay outside contractors. The skill of facial approximation is closely associated and related to forensic anthropology in that an artist specializes in the reconstruction of the remains of a human body. Generally this discipline focuses on the human face for identification purposes. The forensic artist can create a facial approximation in a number of ways to include 2D (drawings), 3D (sculptures) and other methods using new computer technology. Forensic artists generally can add greater character and make their subjects come back to "life".
