Taken as a whole, the indoor environmental quality (IEQ) is concept that deals not only with thermal conditions, but it also goes much further, because includes air (IAQ), illuminance or acoustic comfort. Among different categories of buildings, schools are one most important in society especially future generations spending more than 6 h/day and ensuring them healthy comfortable environment must be top priority. The purposes this research were to better understand school children's IEQ...

Air pollution risk factor on human health was surpassed only by high blood pressure, tobacco use and poor diet. Total number of deaths due to air worldwide estimated 6.67 million people in 2019. In the European Union, 97% urban population is exposed levels fine particulate matter above latest guideline set World Health Organization. accounts for 20% newborn worldwide, most related complications low birth weight preterm birth. Low are responsible 1.8 worldwide. Bucharest capital city Romania...

Abstract This article reports the development of a systematic methodology for evaluation gas-phase filtration models. In this approach, two sets experiments are performed. For first, all required model input parameters quantified either experimentally or empirically. The second set is needed overall validation process. proposed was applied to an existing filter that developed application single mixture contaminants. evaluated gases, namely n-hexane and methyl ethyl ketone, four scenarios:...

This study aims to measure traffic-related air pollution of vehicles with internal combustion, the main source emissions BTEX, organic compounds and NOx, NO2, NO, O3, CO, SO2, PM10 PM2.5, inorganic compounds, in three sites University campus, surrounded by residential areas. According data, around 8000 students are being exposed daily measured level pollution, all 3 studied places campus. A mobile laboratory was used, which continuously measures above mentioned pollutants mete-orological...

This paper presents the research activities and results which have been obtained to develop robotic gloves its control system be used for post-stroke hand rehabilitation. The practical development are shown from a mechanical, sensorial point of view. work is focused on developing lightweight low-cost glove by patients in order regain their movements. Robotic tele-operation was implemented with glove, having attached blending sensors, or mobile device (phone) Android.

The purpose of this article is the assessment energy efficiency and indoor air quality for a single-family house located in Cluj-Napoca County, Romania. studied meant to be an energy-efficient building with thermal insulation, low U-value windows, high boiler. Increasing leads lower quality, due lack natural ventilation. As experimental campaign regarding revealed, there need find balance between consumption air. To achieve superior proposed mitigation systems (decentralized mechanical...

The paper presents the developed hardware and software framework for affective computing during laboratories classes. addresses measurement of student's cognitive states based on some sensors. It is useful to know state student, because teaching staff can change educational process in order increase motivation, attention engagement that student.

Nowadays, the enhancement of existing building stock energy performance is a priority. To promote renovation, European Committee asks Member States to define retrofit strategies, finding cost-effective solutions. This research aims investigate relationship between initial characteristics an residential buildings and different types solutions in terms final/primary consumption CO2 emissions. A multi-objective optimization has been carried out using experimental data DesignBuilder dynamic...

The focus of the present research is to study a parametric simulation solar heating system. system consists vacuum panels, storage tank in provide as well domestic hot water regular house. environment Transol, powerful software adapted for many types systems. results show energy production function different collector surface, accumulation volume, orientation, tilt and also shading. For all simulations Constanta, Romania's climate taken into consideration.

This study is presenting pollution level in Bucharest, the sources being mainly traffic or vehicles, that became larger numbers every year. A new mobile laboratory used which able to monitor continuously PM 2,5 , 10 NO x NO, 2 O 3 CO, SO and BTEX. The diurnal variations are presented different environmental conditions: rainy day sunny day, compare results present outdoor influence of meteorological conditions. Particulate matter influenced by rain as well other compounds like Ozone...

To highlight the heat exchange taking place between seawater as primary agent and working fluid (water, glycol or Freon) secondary agent, I have used Simulink softwear in order to creat a new sequence for numerical calculation of exchanging. For optimum transfer we opted counter movement. The model developed view dynamic behavior exchanger consists four interconnected levelsess. In simulations was found that finer mesh whole lead results much closer reality. There been various models...

In Europe, it is estimated that 14% of existing buildings were built before 1919, whereas 26% 1945. Romania, about 31% the date from 1961, contributing to current stock old with historic and architectural value in country. This paper illustrates state alongside a case study representative administrative building Câmpulung, Romania. The analysis Town Hall demonstrates potential energy savings up 47.53% can be achieved by implementing interventions such as upgrading windows, insulating attic,...

This study presents a modern mobile laboratory to monitor outdoor air quality in Bucharest, Romania, with focus on pollutants associated transportation. Particulate matter (PM2.5, PM10), carbon monoxide (CO), ozone (O3), sulfur dioxide (SO2), nitrogen oxides (NO, NO2), and BTEX compounds (benzene, toluene, ethylbenzene, xylenes) were among the significant that examined lab. Meteorological variables such wind direction speed, temperature, humidity, solar radiation also routinely observed...

This paper will introduce the need for research activities done by undergraduate, Master and PhD students as part of their engineering studies. The present engaged in supervised main author this a case study our faculty. Student are becoming an important educational program at University Craiova last years.
