Assessment of Fouling in Plate Heat Exchangers with Machine Learning Algorithms

Ceren VATANSEVER

Fouling is the accumulation of undesired particles on heat transfer surfaces which affects the heat transfer performance of a heat exchanger negatively. The accumulation of these particles prevents heat from being transformed through the heat exchangers by generating a fouling layer-like insulation. The main aim of the thesis is to investigate the machine learning algorithms to classify and predict the fouling status of PHE used in combi-boilers, to generate the background of the predictive maintenance, besides investigating the fouling effect on PHEs in terms of heat transfer and energy consu ...Daha fazlası

Investigation of the Effect of Electrode Material on Antibacterial Activity in Plasma Treatment with Dielectric Barrier Discharge

Merve Gül

Plasma is an ionized gas generated under an electric field that contains photons, free electrons, ions, free radicals, and reactive oxygen/nitrogen species (RONS). Cold atmospheric plasma (CAP) is generated in the cold form under a high electric field at atmospheric pressure. CAP is generated using two methods, Dielectric Barrier Discharge (DBD) and plasma jet. In the DBD method, the electrode configuration, shape, material, and substance from which the dielectric barrier is made are important. Beyond the electrode design and geometry, the barrier and electrode materials can also impact the re ...Daha fazlası

A case study on PV-aided net zero-energy building: the daycare in IKCU

Loic Rebnodji DJANA

At the core of our growing societies, energy supply stands as one of the major concerns today, and it will be an inevitable challenge for our near future. As the nations are looking to find solutions for the transition from fossil fuels – depleting at a high rate – to alternative energy sources, solar energy through PV cells is getting attention as an affordable and easily implemented option especially for power supply in commercial and residential buildings.

Post-Earthquake Spinal Cord Injury: Role of Physiotherapy and Rehabilitation

TURHAN KAHRAMAN

This review examines the crucial role of physiotherapy and rehabilitation in the management of post-earthquake spinal cord injuries (SCI). After an earthquake, patients with SCI require specialized and intensive rehabilitation programs to promote recovery, prevent complications, and enhance their quality of life. This article reviews the pathophysiology of post-earthquake SCI, the various clinical and functional assessments used to evaluate severity, and the different treatment options available including pharmacotherapy, surgical interventions, and rehabilitation. This review discusses the ch ...Daha fazlası

3D Modelling Performance and Usage Area Analysis of Popular UAVs in the Surveying and Mapping Industry

Metehan MARAL

3D realistic models are used in many fields such as engineering, archaeology, and city planning. The most effective technique used to create these models is the photogrammetry technique. The hardware and software features of the unmanned aerial vehicles to be used to implement this technique are of great importance. Many different unmanned aerial vehicles can be used for photogrammetric studies in the surveying and mapping industry, and therefore users have difficulties choosing needed unmanned aerial vehicles for their studies. In this study, 3D modelling performance and usage areas of popula ...Daha fazlası

Mongolia: social and economic issues

Along with the interest in general Turkish history, the interest in the history, language and culture of the Mongols has also increased; researchers who prefer this field as a field of specialization have increased. Especially in recent years, Turkish and Mongolian academics have carried out joint studies, workshops and conferences in the field of history, language and culture, and shared them with the scientific world. This historical interest in the Mongols and the geography of Mongolia has also triggered the interest in the contemporary life, social and economic situation of Mongolia. Izmir ...Daha fazlası

Geometrical Optimization of Dimpled Double-Pipe Heat Exchangers for Nanofluid-based Natural Circulation Loops Operating at Lower Temperatures

Nur Çobanoğlu

Excessive use of global energy sources causes negative environmental impacts and a reduction in the available energy resources. Therefore, energy efficiency is the main scope of engineering studies. Since household refrigeration accounts for a large portion of the energy consumption rate in buildings, several innovative techniques have been developed to improve the energy efficiency of vapor compression refrigeration systems. Suction line heat exchangers are considered one of these techniques and they are used to avoid the presence of liquid at the compressor and to prevent sweating on the suc ...Daha fazlası

Investigation of the Relationship between COVID-19 Illness Perceptions and Vaccine Attitudes of Midwives and Nurses Working in the Field of Women's Health

Objective: It is known that negative attitudes toward COVID-19 vaccines and unwillingness to vaccinate are higher in women than in men.
