By extracting and extrapolating data we reach the highest stage of scene understanding. In the past few years it proved to be an essential part in computer vision applications. It goes further than object detection by bringing machine perceiving closer to the human one: integrates meaningful information and extracts semantic relationships and patterns. Researchers in computer vision focused on scene understanding algorithms, the aim being to obtain semantic knowledge from the environment and determine the properties of objects and the relations between them. For applications in robotics, gaming, assisted living, augmented reality, etc a fundamental task is to be aware of spatial position and capture depth information. First part of this paper focuses on deep learning solutions for scene recognition following the main leads: low-level features and object detection. In the second part we present extensively the most relevant datasets for visual scene understanding. We take into consideration both directions having in mind future applications.","PeriodicalId":330949,"journal":{"name":"Bulletin of the Polytechnic Institute of Iași.

Since the beginning of this millennia the numbers of EVs have increased from thousands to millions nowadays. The impact of EVs charging, over the Electrical networks has been studied in many publications, and everybody reached the same conclusion: if EV’s charging is not managed, the energy industry will suffer; increased investments, new energy production facilities will lead to increased energy prices. The concept of managing the EV’s charging process is connected to Smart Grid concept, and many publications are stating that a single centralized entity should regulate the chargingprocess. As such, in this paper a similar centralized EV charging control algorithm in low voltage distribution networks (LVDN) is proposed. The proposed algorithm, is regulating the EV charging power, while considering the LVDN network constraints. Specifically, the voltage constraints are taken into account, because the voltage levels within the network are a power supply quality indicator.","PeriodicalId":330949,"journal":{"name":"Bulletin of the Polytechnic Institute of Iași.

Thus, in order to use the photovoltaic energy with a higher efficiency, the methods of traditional load management are involved in residential sector in order to ensure an optimal balance between demanded load and photovoltaic generated power. The concept of Home Energy Management System is an action taken by the consumer and it is part of the concept for Demand Load Management. The most important thing in implementation of this algorithm is to perform a classification of the electrical appliances. Using the Matlab simulation, in this paper has been generated a consumption load profile based on a list of appliances specific to residential area. Based on generated load profile, in the paper has been extracted in several graphs, the power of the equipment that supports and does not support changes in the operating program. Previously, a classification of these appliances has been conducted, the most important aspect taken into account in their classification being the minimum impact on the user’s comfort.","PeriodicalId":330949,"journal":{"name":"Bulletin of the Polytechnic Institute of Iași.

The analysis was performed using two databases which contain IR images with a spatial resolution of 640x480 pixels. The first database was acquired in our laboratory and contains 400 eye images and the second database is a selection of 400 images from the publicly available CASIA Iris Lamp database. The results obtained by applying the segmentation based on the CNN architecture were compared to manually-annotated ground truth data. The results obtained are comparable to the state of the art. The purpose of the paper is to present the implementation of a robust segmentation algorithm based on the U-Net convolutional neural network that can be used in eye tracking applications such as human computer interface, communication devices for people with disabilities, marketing research or clinical studies. The proposed method improves uppon existing U-Net CNN architectures in terms of efficiency, by reducing the total number of parameters used from 31 millions to 38k. The advantages of using a number of parameters approximatly 815 times lower than the original U-Net CNN architecture are reduced computing resources consumption and a lower inference time.","PeriodicalId":330949,"journal":{"name":"Bulletin of the Polytechnic Institute of Iași.
