CdO Thin Film and powder nanoparticles have been produced using the sol-gel method. The X-ray diffraction technique is used to evaluate structural properties of powder CdO at different annealing temperatures 623, 673, 723 (K). It indicates that CdO nanoparticles in nature have a polycrystalline cubic structure. The size of the crystallite (D) is in the middle of the range 23.14-46.65 (nm). As the annealing temperature increases, the crystallite size increases. Also, dislocation density (δ), strain (ε), and texture coefficient TC(hkl) were calculated. The energy band-gap and refractive index were estimated. Band gap energy decreases with increasing annealing temperature and refractive index increases with increasing annealing temperature.

An overview of existing urban software mobile applications of the transport and economic direction is given. A model of a functional rationalizer of consumer behavior is being built. The software model of the functional rationalizer of consumer behavior (SM FRCB) was developed for the first time. PMFRCB allows the user to expand the number of his preferred needs (occupations, activities) during the daily cycle through intelligent recommendations. Also, SM FRCB allows you to optimize needs (activities, activities) at the cost and rate of their use. The SM FRCB is made in Python_3 using the libraries matplotlib, collections, numpy, pyplot, mplot3d. The analysis of consumer behavior before and after using the functional rationalizer model is carried out. The graphical results of a structural analysis of the costs of old and new consumer behavior, analysis of consumer behavior within the boundaries of the theory of possibilities and the model of transport behavior of a resident before and after applying the functional rationalizer model are presented. The prospects of further improving the SM FRCB are considered.

City University of Hong Kong Hong Kongn automatic visible spectrometer based on a non-collinear acousto-optic tunable filter (AOTF) is constructed for high-speed spectrometry. Its spectral filtering characteristics such as relationships between the radio-frequency (RF) driving frequency and the output central wavelength the output bandwidth and the central wavelength its typical spectral point spread function (PSF) and so on are studied systematically. The preliminary measurement results of AOTF spectrometer show that it is a solid-state high-speed easily controllable by computer-programming rugged and compact spectroscopic device in comparison with a conventional grating spectrometer and has the potential for widespread spectrometric applications.

In recent years, robots have started to become more commonplace in our lives, from factory floors to museums, festivals and shows. They have started to change how we work and play. With an increase in the population of the elderly, they have also been started to be used for caregiving services, and hence many countries have been investing in the robot development. The advancements in robotics and wireless communications has led to the emergence of autonomous caregiving robot teams which cooperate to accomplish a set of tasks assigned by human operators. Although wireless communications and devices are flexible and convenient, they are vulnerable to many risks compared to traditional wired networks. Since robots with wireless communication capability transmit all data types, including sensory, coordination, and control, through radio frequencies, they are open to intruders and attackers unless protected and their openness may lead to many security issues such as data theft, passive listening, and service interruption. In this paper, a secure web-based communication framework is proposed to address potential security threats due to wireless communication in robot-robot and human-robot interaction. The proposed framework is simple and practical, and can be used by caregiving robot teams in the exchange of sensory data as well as coordination and control data.
