Biological Seawater Desalination Using Green Algae And Cyanobacteria, Abdul Mannan Zafar

Thesis/ Dissertation Defenses

Water shortage in many coastal parts of the world is reaching alarming situation, including the United Arab Emirates. Urbanization and rapid population growth are generating critical water demands with an increase in per capita consumption. Seawater is usually treated by membrane processes such as reverse osmosis (RO). However, this technology is energy intensive and generates excessive brine as a waste. The solution to this problem can be found in natural remediation techniques that can reduce salt concentration from seawater, such as halophytes. A salt-tolerant species can consume Na+ and Clions and increase cellular growth which is termed biological desalination or …

Design And Application Of Circular Edge-Fed Linearly Polarized Patch Antenna With Enhanced Bandwidth And Gain For Respiratory Monitoring Systems, Mo’Ath Akram Al Hayek

Thesis/ Dissertation Defenses

This Master's thesis explores the design and application of a circular edge-fed patch antenna for respiratory monitoring systems. The antenna, fabricated from a thin copper adhesive sheet, demonstrates compatibility with textile materials of low thickness and a relative permittivity of 1.3. Using CST Studio Suite 3D EM simulation software, the antenna's design was optimized through extensive trials, achieving improved bandwidth and gain. Our findings indicate that the antenna successfully differentiates between various breathing patterns, including slow, normal, and fast breathing rates. The study's managerial and research implications extend to healthcare, wearable technology sectors, and the broader scientific community. The research …

Leaching Properties Of Fly Ash From Duvha Power Station In South Afric, Jabulani Veloso De Matsimbe, Megersa Melo De Dinka, David Caetano Olukanni, Innocent Oliveira Musonda

UBT International Conference

Fly ash and phosphogypsum are abundantly available in South Africa. However, landfilled industrial waste materials interact with the environment leading to groundwater, air, and soil pollution. This study aims to determine and quantify the heavy metal concentrations in fly ash from the Duvha power station and compare the results with US EPA regulatory limits. The TCLP and ICP-MS methods are used for leachate measurements. The results showed that the fly ash can be considered non-hazardous since the amounts of toxic elements such as Hg, Pb, Cu, Cd, Zn, Ni, As, P, Co, Se, and Mn are below the US EPA …

Distance Protection And The Importance Of Precision Measuring Equipment, Qendresa Syla

UBT International Conference

As we know short circuits are an inevitable phenomenon for the electrical power system. These damages must be quickly detected by the relay protection system and the damaged part must be isolated quickly. The defense of a line is of particular importance. When a defense system is designed, a compromise must be made between economics and performance, independence and security, complexity and simplicity, accuracy and speed.

From a technical point of view, the correct performance of the relay protection has been of particular importance over the years. It is not desirable for a node of the system to be taken …

Evaluating The Impact Of Demand-Side Response In Kosovo During The Energy Crisis: What Can We Learn?, Arven Syla, Avni Alidemaj, Martin Patel

UBT International Conference

The energy crisis in Europe due to war between Ukraine and Russia has led to a unprecedented situation. The volatility in gas supplies and prices has driven the wholesale electricity prices to increase enormously. Fortunately, this crisis has prompted many European countries to prioritise energy sector and advance green agendas. While the efforts to mitigate the energy crisis has primarily focused on the supply side (i.e., subsidies to energy suppliers), less attention has been paid to the demand-side. In this study, we examine how Kosovo managed the electricity crisis and consider the impact of demand-side. We analyze the data of …

The New Epbd Directive A Case Study Of A Renovation Of A Country House In Kosovo, Kliton Bylykbashi, Besar Veseli, Visar Krelani

UBT International Conference

With the "green houses" directive, the European Union intends to reduce GHG emissions by 55% to 2030 compared to 1990 levels and achieve zero emissions by 2050. Reducing emissions of polluting gases and fighting global warming are two objectives of the utmost importance for Europe, pursued through a policy that encourages the ecological transition. One of the most discussed interventions in this sense is the so-called Green Homes Directive or the EPBD Directive which aims to gradually eliminate buildings with inadequate energy performance by promoting the redevelopment of energy-intensive buildings. How can Kosovo respond to this objective at this moment? …

UBT International Conference

The objective of the research was to experimentally examine the corrosion of steel fibers in two media: a solution containing potato dextrose and calcium chloride (S1) (nutrient of the biological agent Oomicetum Pythium aphanidermatum that facilitates the self-healing of cementitious matrices), and water (S2). The corrosion process was accelerated by the Cebelcor method for 15 days, with immersion/emersion cycles of 5 and 19 hours, respectively. The results revealed that the corrosion of the fibers in solution S1 was 10.64% higher than that in S2. Regarding cross-sectional loss, the corroded fibers in S2 showed linear behavior, unlike those in S1, which …

Dynamics Of Simply Supported Beam Members Subject To Vertical Seismic Acceleratio, Francesco Foti, Luca Capacci, Bruno Dal Lago

UBT International Conference

Despite in most cases vertical seismic acceleration is disregarded in practical structural design, mainly due to the uncritical actions of the pertinent load combination, current standards prescribe the structural check of long-span and pre-stressed beam members subjected to vertical acceleration when they are located in high seismic hazard areas. Current design approaches focus on either finite element calculation, which does not provide a logical guidance to the designer for the problem, or, alternatively, on simplified calculations typically assuming lumped masses concentrated at midspan of the horizontal member. The latter approach does provide only an indicative solution affected by arbitrary modelling …

Assesment Of Bicycle Sharing Programs From A User Perspective: Kaybis, Hatice Göçmen Demir, Y .Kağan Demir, Anil Uruç

UBT International Conference

Bicycles are highly preferred as an efficient means of transportation today, particularly in terms of sustainability. There are currently over 1000 Bicycle Sharing Programs (BSPs) worldwide that are organized to promote the use of bicycles with individual or public transportation in an integrated manner. The first implemented BSP in Turkey is known as KAYBIS, and many other cities are also considering or planning similar programs. However, the availability of information and user statistics related to KAYBIS does not clearly indicate the level of adoption of BSP by users.

In this study, the factors influencing users' preferences for KAYBIS were determined …

Splitting Tensile Strength Prediction Using Machine Learning Based Optimization Algorithms, Lukesh Veloso De Parida, Sumedha Melo De Moharana, Sourav Kumar Giri

UBT International Conference

The usage of recycled aggregates in construction materials has received a lot of interest because of its potential to minimize environmental consequences and the loss of natural resources. The prediction of splitting tensile strength, a crucial mechanical attribute determining structural performance, is an integral part of assessing the feasibility of recycled aggregates for construction. Traditional techniques for evaluating the splitting tensile strength of recycled aggregates rely on advanced and time-consuming laboratory testing, which may be costly and inefficient for large- scale applications. This work proposes machine learning-based algorithms for predicting the performance of splitting tensile strength. In this research, 257 …
