Abstract: The aim of the TULIP (Target ion soUrce for short-Lived Isotope Production) device is dedicated to the production of short-lived neutron deficient ions using ISOL (Isotope Separator On Line) method. The efficiency of such device depends on several parameters: diffusion, effusion and ionization processes, which must be optimized to maximize the efficiency. As short-lived, the elements must release from the stopping material in a short time, explaining our focus on the diffusion parameters and our effort to build a database gathering diffusion parameters concerning a large variety of target-element combinations. For this purpose, an important bibliographical work is underway in order to collect as much data as possible. An another offshoot of the TULIP ISOL project is to build a system (MELODICA device, MEsure en Ligne de cOefficients de DIffusion et de temps de Collage Atomique) to systematically measure the diffusion coefficients of atoms out of materials at high temperatures. Moreover, to get rid of constraints related to the use of radioactive elements, the MELODICA device uses stable atoms and embed a FEBIAD (Forced Electron Beam Induced Arc Discharge) source to ionize a large panel of elements. With this device, it will be possible to systematically extract several diffusion coefficients during the same experimental period, and to compare the relative release of different atoms out of materials currently used in the ISOL systems.

Abstract: The present pandemic situation has made people not go out anywhere because it’s getting difficult to learn the concepts briefly for both lecturers and students. Concepts are learned through videos, but reading is also an important aspect of learning. This paper talks about providing books and notes in online mode to read and recommend books based on facial expressions captured from the user. This paper aims to extract faces from an image, extract the expression (eyes and lips) from it and also classify them into six types of emotions, which are Happy, Fear, Anger, Surprise, Neutral and Sad. The algorithm used for facial expression recognition is the Convolutional Neural Network algorithm, also known as CNN.

Abstract: Medical attention is critical to living a healthy life. If you have a health concern, however, it is quite difficult to seek medical help. The idea is to create a medical chatbot that can assess symptoms and provide a list of illnesses the user might have using AI and other biometric parameters. In medical diagnosis, artificial intelligence aids in medical decision making, management, automation, administration, and workflows. It can be used to diagnose cancer, triage critical findings in medical imaging, flag acute abnormalities, assist radiologists in prioritizing life-threatening cases, diagnose cardiac arrhythmias, predict stroke outcomes, and aid in chronic disease management. Medical chatbots were created with the goal of lowering medical costs and increasing access to medical information. Some chatbots act as medical guides, assisting patients in becoming more conscious of their ailment and improving their overall health. Users will undoubtedly profit from chatbots if they can identify a variety of illnesses and provide the necessary information that may help the user to understand the predicament, he/she might be facing. The main idea is to create a preliminary diagnosis chatbot that allows patients to participate in medical research and provide a customized analysis report based on their symptoms

Abstract: Nowadays, a lot of information on structure and properties of a wide variety of substances and materials has been accumulated. Yet, there is a lack of systemic universal approaches to assessing their structure and properties, including developing the effective approaches for monitoring and analysing various materials. It is of special interest in this respect to assess the effects of the chemical bond type on structure and properties of substances and materials. However, searching for necessary data on the effects of chemical bonds on structure of substances and materials is a rather laborious process. The authors, relying on the intermediate nature of chemical bonds of compounds of elements in any metallic and non-metallic material, as well as the system of chemical bonds and compounds developed by them in the form of a “Chemical Triangle”, produced an algorithm for creating a computer programme. It implies systematising of the database on the effect of chemical bond type on its length and energy, structure and various physicochemical and mechanical properties of homo-and heteronuclear compounds and materials. Development of such a specialised computer programme greatly simplifies this process, providing more efficient analysis and control of materials.

Abstract: The polymeric plastic tube can encase concrete and provide an external shell for confining and insulating concrete core from the impact of the surrounding environment. The effect of the tube and concrete strength on the concrete-filled plastic tubes (CFPT) stub columns specimens was investigated. Test results show that the tube provides passive confinement to the concrete core, which increases both the maximum peak load and the ultimate strain capacities. However, the tube has low stiffness, which affects its confinement capacity and hindrance its applications for structural use. To examine the role of tube stiffness and express the strength of a concrete-filled plastic tube, a previously proposed normalized stiffness approach for both active and passive confinement of FRP-confined concrete was adopted for the present study. From the perspective of stiffness and to better understand the behavior of CFPT specimens under uniaxial compression loads, a database of recent studies were assembled combined with the results of the present study. Several existing strength models for FRP-confined concrete were also used to predict the mechanical strength of CFPT. Two models were proposed with good predictions of the experimental results of the database.

Abstract: After the 2010-2011 Canterbury earthquakes, much of the Christchurch Central Business District (CBD) was demolished and a new city has emerged in its place. A series of interviews conducted with key professionals involved with the reconstruction, together with data collected from various sources has made it possible to identify some of the drivers that have influenced decisions about the selection of structural material and specific structural systems used. Here, quantitative results obtained from this study are presented, in terms of structural systems, size of building in terms of square foot, as a function of time since the earthquake. The Christchurch rebuilding experience is most significant, providing a unique insight into some of the mechanisms that can dictate structural engineering decisions during the post-earthquake reconstruction of a modern city.

Abstract: For years now, the industrial manipulators have substituted human in many types of works during the manufacturing process. With robots the production rate increases, as does the quality of the product. The application of industrial manipulators increases the safety in the factories which in turn leads to savings. However, there are several difficulties in introduction of robotics into the production line. One of them is usually large cost of purchase and implementation of the robot. The proposed concept of the intelligent system for tool exchange is to address the stated issue. The aim of the system is to provide a mechanism for quick tool exchange supported by a decision making module that will constitute the self-reconfigurable industrial manipulator that is able to assess the situation at the production line, recognize the product and make decision on the operations to be performed, their sequence and which tool to use to perform that operation. Such a system of manipulator equipped with functions for reconfiguration and adaptation will be a solution for all applications where the production assortment changes quickly and is made in short series, and in particular for SMEs, which cannot afford purchase of several robots. They would buy one instead and let it perform variable tasks.The article briefly presents the concept of the hardware part of the exchange system, which includes both construction and the electronic modules for the tools, and concentrates on the concept of software expert system and database that allows intelligent decision making. The software control of the system is divided into four levels: the basic level, technical level, task level and procedure level. The basic level defines the movement of the robot such as: positioning, rotation, approach to the position etc. This level uses to control system of the applied manipulator and the data contained in the electronic modules of the tools. The basic level reflects the typical low-level control of the manipulator. The technical level defines the technical movement of the robot, small procedures related to the calibration of the tools, operation with the tool magazine (picking up and putting away) and related to tool maintenance – locking, unlocking, power supply, air supply and similar. The task level defines the operations related to the task performed on the object. Depending on the defined task the proper tool is selected (e.g. gripper, camera or a laser scanner) and, based on the data collected from sensors, performs the operation (e.g. scans the surface of the object). The highest level of control is totally independent on the hardware control system of the manipulator and the hardware of the robotic stand. Using the available databases and the recognition systems (e.g. cameras) makes decisions on what type of object appears on the production line and what operation is to be performed. The operations are defined as metacode that is interpreted and performed by lower control levels structurally bound to the control system of the manipulator.

Abstract: The control of roads traffic, of noise, of all other problems which occur on national road sections are much more manageable through Geographic Information Systems. The possibility of changing parameters in real time from a database, allows rapid information on problems encountered and efficient solutions at a more sustained rate.This paper presents a proposed solution to improve the Geographic Information System by adding noise data, by carrying out a case study on the road section Sag - Voiteg that connects Timisoara (Romania) and Belgrade (Serbia). The existing GIS system was established in 2012 according to the legislation in force at the time. As Year 2017 will mark the next stage of issuing the noise maps according to the rules set by CNOSSOS-EU, the measurements done for this study will follow these new methods. CNOSSOS-EU accurately describes the objectives and methodology requirements, establishes clear criteria for road traffic and sound propagation.The advantage of uniformity standards and methods of control in all EU Member States allows comparative studies on pollution, the number of people affected, etc.

Abstract: Construction waste is a material of waste or excess building materials that are not used either in the original or debris from construction, structural repair, and improvement work, house demolishing, buildings and other structures. Wastes are from excess building materials from dredged material and stumps of structural repairs, improvements and work to destroy sidewalks, homes, commercial buildings and other structures. Construction waste also refers to soil, rock and vegetation removed during land levelling works or civil engineering works and works related to road maintenance. Illegal dumping site is places other than permitted facilities to dump waste such as transfer stations and landfills. The objectives of this study are; (1) identify illegal dumping of construction waste distribution in Parit Raja; (2) quantifying the illegal dumping of construction waste generated in Parit Raja and; (3) develop Geographic Information System (GIS) map for illegal dumping construction waste distribution in Parit Raja.
