Aiming at the mobility needs of semi-disabled patients, an intelligent nursing wheelchair was designed to realize the autonomous movement of the wheelchair. First, the Cartographer algorithm based on graph optimization was introduced to wheelchairs to locate them in unknown environments. Secondly, multiple sensor information is fused to improve the positioning accuracy. Finally, machine vision, SLAM, path planning and other technologies are applied to the wheelchair to improve its intelligence and interactivity. Finally, an intelligent nursing wheelchair prototype is built, and the autonomous mobility system of the wheelchair is proved to have good robustness through experiments.

Forests, one of the most valuable and necessary resources and protect earth's ecological balance, are a natural habitat to animals and forest products are vital in our lives in many direct and indirect ways. But wildfires can cause critical damage to grounds and many other resources like properties, human life, wildlife in superabundant amounts. Wildfires burn acres of land and destroy everything in their paths in mere minutes. Wildfire destroys homes, animals, trees and plants, wildlife as well as vegetation. The effects of wildfires are numerous and wide-ranging. it causes a hugely significant impact on the economy, environment, heritage and social fabric of rural areas. Naturally caused wildfires can be predicted using factors[3] like temperature, humidity, soil moisture, pressure and many more. In this paper, the prediction of forest fires by machine learning using some operational monitoring over a region and encountering changes in climate using different sensors are advocated. The Wildfire Prediction System (WiPreSy) monitors and records changes in climatic parameters and predicts the intensity of forest fire based on real-time data, thus avoiding the massive loss due to forest fires.

The aim of the research was to develop a concept of a remote measurement system for air quality management using IoT for an apartment with a mechanical exhaust system. The constant monitoring system with the possibility of manual control by the occupants allows teaching the occupants how to chose optimal settings with the biggest impact on the air quality. Additionally, using cloud data analysis, the measurements can be compared with simulations performed before the building construction. This allows choosing the proper apartment depending on the foreseen occupancy schedule and the family size.

Driven by the exploding computing service demands from various intelligent mobile applications, an increasing amount of research efforts have been devoted to mobile edge computing (MEC). Meanwhile, unmanned aerial vehicles (UAVs) have found a great success in assisting existing wireless systems due to their flexibility and low cost. The advancements in these two closely related fields foster the development of the recently advocated UAV-assisted MEC paradigm, which is expected to bring unprecedented performance gain to the existing ground-based MEC systems. Nonetheless, existing works on UAV-assisted MEC mainly focus on the single-UAV scenarios and often assume static system states. In this paper, UAV swarm assisted MEC is considered where multiple collaborative UAVs are employed to help the terrestrial edge server to provide better edge computing services. However, the complexity of using existing methods to find the best dynamic coordination strategy in UAV swarm assisted MEC becomes intractable when the number of UAVs increases. To resolve this challenge, a novel decentralized deep reinforcement learning algorithm is proposed in this work, which can reduce the complexity by orders of magnitude. In addition, simulations are conducted to show that by using the proposed algorithm, the UAV swarm can efficiently learn a good dynamic coordination strategy and thus achieve a significantly better performance than the baseline scheme.

Quality control of food products, including beverages, during the production process is an important task that can be successfully solved by information technology. Currently, quality control of wine, beer, juices and other beverages is carried out using biochemical control, which takes a time and requires the application of complex analytical devices under the control of qualified personnel. The development of information technologies, biosensors, sensor networks makes it possible to solve the problem of quality control of various beverages in express mode. The main contribution of this paper is the design and prototyping of wireless amperometric biosensors and wireless sensor network (WSN) on their base to monitor the concentration of various components in beverages. The WSN architecture was modified for technological process of winemaking. Wireless biosensors were tested with different types of enzymes on different concentration of solutions. Such tests confirm the possibility to use the wireless biosensors on some stages of technological process of winemaking. The upgrading wireless nodes by sensing unit with particular enzymes will allow covering all technological process.

A wireless sensor network ( WSN) is a communication network with ad hoc configuration consisting of a number of tiny, low-power, low-cost sensors which are normally distributed in a decentralized fashion and have limited processing capability. WSNs have found a wide range of applications such as industrial process control, healthcare monitoring, surveillance, forest fire detection, natural disaster detection, target tracking, among many other applications. It is known that WSNs are resource-constrained, hence, energy efficiency is crucial for all applications of WSNs to extend the life span of the sensors' batteries. The most energy consuming operation in WSN is data communication, hence, it is important to reduce amount of data transmission through WSNs without significantly affecting the transferred information. In this paper we will focus on two directions of data-efficient signal representations that are expected to provide WSNs with sufficient energy control. The first direction is the use of intelligent short word-length (SWL) systems via embedded sigma-delta modulation, and the second direction is to use compressive sensing (CS) with chaotic sequences. If security is a factor, then CS via chaos can support secure communication in addition to its main function as a technique for data compression.
