The Availability Improvement of Uninterruptible Power Supply by Stabilizing Node Application at Control Part

The UPS (uninterruptible power supplies) are essential power infrastructure components of systems designed for critical application, including data centers. High availability achievement is a very important factor related to UPS performance, consequently to proper critical application functionality. Generally, UPS have a limited input voltage window, referring to the nominal input voltage value. Goal of this paper is to prove larger voltage window, without affecting normal UPS operation. Larger window will result on less commutation, backup and normal mode reduction, and consequently duty time of batteries reduction, too. Thus, under these conditions, it is to be expected availability improvement. The stabilizing node model, applied at UPS's control part through this paper is presented. UPS's behavior with an implemented stabilizing node is observed at few sites. In order to analyze and conclude about UPS's performance under these technical conditions, simulation results are further presented.
Asymmetric Multilevel Converter for High Resolution Voltage Phasor Generation

Recent publications on so called multilevel inverters deal with series connected cells, mainly developed for the increase of the output-voltage magnitude, in order to meet the classical design levels of medium size motors in the lower megawatt power range [1], [2], [3], [4]. In all well-known multilevel topologies, generally a regular or symmetric voltage share over all partial sources has been chosen, with as main goal a better use of the individual silicon devices regarding the possible blocking properties. The definition of the resulting output voltage has generally been sufficient due to the high number of series connected cells. In the proposed solution, the main efforts are set to the aspect of getting a higher resolution of the voltage phasor, in relation with the use of motors with strongly reduced leakage inductances. Together with the specification of a limited current harmonic content, even the frequency of the fundamental component is an important parameter. One application field will be the variable speed drives for ultra-speed kinetic energy storage.
Fix your vowels: Computer-assisted training by Dutch learners of Spanish

It is common knowledge that foreign learners struggle when it comes to producing the sounds of the target language accurately. Research in L2 speech acquisition has shown that in order to achieve native-like production of sounds in a foreign language, the learner must first become proficient in perceiving these sounds. That is, if Dutch listeners perceive Spanish vowel sounds through their first language categories, they are likely to produce them through their L1 categories, i.e. in a non-native way, thus with a foreign accent. This study analyses the effect of the vowel training programme Fix your vowels on the production of Spanish vowels by native speakers of Dutch. The findings confirm that computer training exerts a positive effect on the production of Spanish vowels and that this effect is also related to the desire to acquire a native accent.
ISSUES OF STRUCTURED VS. OBJECT-ORIENTED METHODOLOGY OF SYSTEMS ANALYSIS AND DESIGN

In recent years, there has been a surge of interest in object-oriented (OO) methodology in the analysis and design of a system. However, there is a dilemma as to how best fit the OO topics with the existing coherent discussion of structured approach of developing a system. This paper addresses some issues related to the two design paradigms.
Intelligent fastening with A‐BOLTTM technology and sensor networks

Threaded fasteners appear to be the best low cost option for applying a desired clamp load to assemble a joint, which can be disassembled, if necessary, at a low cost. A large number of joint failures are due to inadequate tension on the joint. Most conventional tightening methods only provide a vague indication of the bolt tension. In this paper we will discuss the development of the A‐BOLT™ system, which can measure the tension in the mechanical bolt to ±1 per cent accuracy of the proof load. The key element of the system is a specially designed mechanical bolt with a top‐mounted sensor to measure the bolt elongation. We will also describe the development of different generations of the A‐BOLT™ system and its industrial applications. Finally we will present an overview of research on the cluster based networking of wireless sensors to minimize energy consumption in a network of sensors.
Consumption of Food by College Students using Ml Algorithms

We are well aware of the many problems that our current generations are facing. From all these new enhancements in the real world, it has been quite hard for them to keep up with everything evolving around them. Keeping all this in mind, they work day in and out to make sure that their knowledge of their surroundings up to date. However, we believe that they fail to take care of themselves in the process correctly. No matter how much a particular individual may withstand in terms of workload, stress, or other mental & emotional barriers, our physical body will always be the critical aspect to overcoming them. Most people believe that working out and maintaining physical fitness are the significant aspects to sustain an excellent physical form, but they simply overlook the most crucial element which is their eating habits [1]. Although our body may be physically fit, the nourishment of our body depends on the eating styles that we follow on a day to day basis. Food is what nourishes our body with most of the proteins & minerals that we require; without it, we wouldn't be able to accomplish much. On conducting worldwide research on people's lifestyles, we were able to conclude that over the past 33 years, the obesity rate among human beings has increased by a mere 27.5%. What seems to be the most thoughtful yet intriguing fact is that although many people are overweight as well as obese, they still believe that their eating habits are healthy [2]. Most people are living in the dilemma of the fact that they maintain a healthy lifestyle. We aim to study the views on a healthy lifestyle as per the norms of our current generation. We want to analyze their daily eating habits as well as their thoughts on their lifestyle. So the question that remains is “What exactly is a Healthy Eating Lifestyle? ”[3]To know the accuracy of our data set we use the machine learning algorithms like Support Vector Machine (svm), Naïve-Bayes Classifier which are used for both classification and regression [4]
Evaluation of the effect of the new approach of local air quality review and assessment in Great Britain: the updating and screening assessment phase

The local air quality management framework in Great Britain stems from the Environment Act 1995, Part IV. The Act places responsibility on local government to review and assess air quality in their areas of jurisdiction. The process of review and assessment is undertaken in Rounds. In Round 1 of review and assessment, the Government recommended in its guidance documents a three-stage approach, whereby each stage increased in detail and complexity. In 2003 the Government suggested a new two-stage prescriptive approach to Round 2 review and assessment. The first step in this approach is an Updating and Screening Assessment (USA) in which each local authority identifies changes to local circumstances since the first round and completes a risk assessment to identify locations where Air Quality Objectives (AQOs) are likely to be exceeded. Where a risk is identified, the local authority must progress to the second step; a Detailed Assessment (DA). This paper examines 388 USA reports from different local authorities across Great Britain to identify AQOs at risk of exceedences and their sources. The methodology adopted is an appraisal of the USA reports submitted to the Government and the national archive of air quality review and assessment reports. Results show that 201 local authorities are progressing to a DA for pollutants previously identified in Round 1 as at risk of failure to meet the AQOs (nitrogen dioxide, particles (PM10), sulphur dioxide) and for other pollutants not previously identified (e.g. benzene). It was concluded that the new prescriptive approach to air quality review and assessment resulted in identification of new potential AQO exceedences.
Agent-based simulation of German peacekeeping operations for units up to platoon level

Abstract : A significant challenge to the German Military Forces or "Bundeswehr" today is the development of tactics that will enable soldiers airmen and sailors to be successful in small-scale peacekeeping operations. This thesis develops an agent-based simulation for modeling peacekeeping operations at the platoon level. The simulation methodology combines agent-based modeling with discrete event simulation in two software packages called Peacekeeping and TryShoot. These software packages are used to model one part of a map exercise, the Kurzlage PIZREN. The platoon of peacekeeping soldiers utilizes different kinds of tactics against different kinds of approaches by the civilians to reach their goal. This simulation yields insight into the modeled scenario and demonstrates the usefulness of agent-based simulation for the exploration of tactical concepts in a peacekeeping operation.
Advanced Integration in Multi-Scale Mechanics and Welding Process Simulation in Weld Integrity Assessment

The potential to save trillions of BTU’s in energy usage and billions of dollars in cost on an annual basis based on use of higher strength steel in major oil and gas transmission pipeline construction is a compelling opportunity recognized by both the US Department of Energy (DOE). The use of high-strength steels (X100) is expected to result in energy savings across the spectrum, from manufacturing the pipe to transportation and fabrication, including welding of line pipe. Elementary examples of energy savings include more the 25 trillion BTUs saved annually based on lower energy costs to produce the thinner-walled high-strength steel pipe, with the potential for the US part of the Alaskan pipeline alone saving more than 7 trillion BTU in production and much more in transportation and assembling. Annual production, maintenance and installation of just US domestic transmission pipeline is likely to save 5 to 10 times this amount based on current planned and anticipated expansions of oil and gas lines in North America. Among the most important conclusions from these studies were: • While computational weld models to predict residual stress and distortions are well-established and accurate, related microstructure models need improvement. • Fracture Initiation Transition Temperature (FITT) Master Curve properly predicts surface-cracked pipe brittle-to-ductile initiation temperature. It has value in developing Codes and Standards to better correlate full-scale behavior from either CTOD or Charpy test results with the proper temperature shifts from the FITT master curve method. • For stress-based flaw evaluation criteria, the new circumferentially cracked pipe limit-load solution in the 2007 API 1104 Appendix A approach is overly conservative by a factor of 4/π, which has additional implications. • For strain-based design of girth weld defects, the hoop stress effect is the most significant parameter impacting CTOD-driving force and can increase the crack-driving force by a factor of 2 depending on strain-hardening, pressure level as a % of SMYS, and flaw size. • From years of experience in circumferential fracture analyses and experimentation, there has not been sufficient integration of work performed for other industries into analogous problems facing the oil and gas pipeline markets. Some very basic concepts and problems solved previously in these fields could have circumvented inconsistencies seen in the stress-based and strain-based analysis efforts. For example, in nuclear utility piping work, more detailed elastic-plastic fracture analyses were always validated in their ability to predict loads and displacements (stresses and strains). The eventual implementation of these methodologies will result in acceleration of the industry adoption of higher-strength line-pipe steels.

Prototype for the use of ultrasound in supercritical media

The use of power ultrasound together with supercritical CO 2 is a non-conventional promising technique for extraction processes in food industries. Extraction of almond oil, adlay seed oil, pungent from ginger are good examples of the potential use of this novel technology. In fact, power ultrasound represents an efficient manner of producing agitation in the media enhancing mass transfer on supercritical fluids extraction processes. A prototype for the use of ultrasound in supercritical media is presented in this paper. Special attention has been given to the transducer and its behaviour as a function of power and time during operation. Specific software to control and monitoring the parameters involved in the process has been developed. This tool will allow the best conditions for the operation process to be selected.
Agent-Based Intelligent Decision Support Systems: A Systematic Review

Decision-making complexity, in a distributed environment, is due to hard tasks that a system must resolve. This complexity makes researchers focus on looking for solutions to cope with distributed environment problems. Multiagent system (MAS) technology is one of several proposed solutions. This technology rose the challenge in decision-making applications. To date, no systematic review has been conducting, to the best of the authors’ knowledge, to give an overview of a multiagent-based decision-making system in various areas of science or technology. In this study, we review of 58 studies published from 2007 to 2019. The aim of this article is a critical analysis of recent approaches. We try to survey their impact on practice and research. The analysis of the extracted studies is based on three selection criteria that are defined in the paper. All included studies have analyzed from four different points of view: 1) theoretical view; 2) technical view; 3) agent view; and 4) application view. Moreover, we adopt the SWOT analysis to evaluate studied approaches. Multiagent technology is actually in the process of evolution and enhancement with the appearance of new trends in artificial intelligence, such as neural network and deep learning. The results of this review show suggestions for further research and practice.

A framework of an effective online help system to support nurses using a nursing information system

Research Aim and Questions: This research aims to develop a quality framework of an effective Online Help System (OHS) for a Nursing Information System (NIS). This involves the identification of the criteria for an effective OHS. The research questions are what content, structure, functions and aesthetics this OHS should have. The research will also provide guidelines about how to evaluate the usability of an OHS. To learn unfamiliar features or functions of a Nursing Information System (NIS), nurses need effective and efficient assistances. An OHS, which aims to bridge the gap between the complexity of a NIS and nurse-users’ need for simplicity, is one effective solution. However, systematic research on the design and evaluation of an OHS is not common. There is a lack of a comprehensive quality framework that could provide guidance on the design and evaluation of an OHS for a NIS. As nurses are important healthcare workers, their acceptance and usage of a NIS is important for the improvement of quality of healthcare data, it is imperative to conduct this research with strong potential to impact on the adoption of NIS by nurses. Research Methodology: Two phases of investigation were carried out. Guided by a grounded theory approach, we first proposed a quality framework of an effective OHS for a NIS. In order to prove the validity of this framework, an experiment was carried out in which an OHS for an authentic NIS (the Care Planning and Assessment Tool) was developed and evaluated. Various research methods were employed in collecting data, i.e. laboratory-based usability testing, focus group discussion and questionnaire survey. Results: The proposed framework was consisted of the five criteria (i.e. content, structure, functionality, aesthetics, and usability. The CPAT Online Help was designed according to the results of the needs assessment and the forty-three guidelines that reflect the quality indicators in the framework. The results of the heuristic evaluation of the CPAT Online Help shows that the help system highly reflect on the proposed framework. The results of
