Removal of Phosphate from Aqueous Solution by Chitosan-Alginate Beads
Phosphorous is an effective and essential mineral nutrient for the growth of biological creatures and it is very necessary for functioning of ecosystems normally. However, the increase in the usage of phosphorous in lots of parts including industry, agricultural and municipalities causes to pollution of water bodies. Additionally, consumption of water which is rich in content of phosphorous can cause to decrease in the levels of calcium amount of blood and that can result in osteoporosis, hyperphosphatemia and hazard public health. For protection of human health and aquatic ecosystems, the amount of phosphorous should be controlled within the limits (<0.5 mg/L as it has been reported by World health organization). The removal of phosphorous from water bodies relies mostly on the adsorbents usage which are effective. In this study, chitosan-alginate hydrogel beads were prepared by mixing chitosan and sodium alginate solution together and dropping them into calcium chloride solution. Sodium alginate and chitosan mixture causing interpenetrated network improves the resistance of the beads in acidic mediums. For characterization of beads SEM and FTIR analysis were conducted to prove the presence of functional groups and calcium ions which has the main effect in phosphate adsorption. Additionally, UV spectroscopy method was used to study adsorption capacity which illustrated that with increasing adsorbent concentration and time, the amount of adsorbed phosphate increase considerably.
Glamping Tourism, Potentials and Prospects: A View from German Tourism Organizations/Institutions
The outdoor hospitality sector, which incorporates campsites, convoy parks, entertainment vehicle parks, and glamping (glamorous camping); have attracted tourists’ attention worldwide. These forms of holidays are means to escape the overcrowded urban areas, socialization, and opportunity to have a new experience, as well as experience nature and environment first hand. However, glamping as a niche tourism has combined the camping in the nature with a touch of luxury for a niche market. The main aim of this study is to explore the factors that resulted in the growth of this form of tourism. In addition, to explore the characteristics of glamping patrons. Furthermore, the study is focused on the role of glamping as a tourism activity and its relationship with sustainable tourism. For the purpose of this study, a qualitative research method based on in-depth interview with glamping organizers in the case of Germany has been focused. The findings revealed that most of the patrons of glamping are up-market tourists who are seeking a new experience and adventure. Study has also revealed that patrons of glamping are interested in nature and at the same time desire luxurious services and comforts. This type of tourism is somewhat unexplored, and this study is an attempt to fill this gap. Implications and contribution of this study is also discussed.
Sapphires and Superwomen: The Role of Ambivalent Sexism, Religiosity, and Internalized Racism on Perceptions of Intimate Partner Violence
This study was conducted with the aim of exploring a previously understudied role of internalized racism and Black female Stereotypes (the Sapphire and Superwoman) in encouraging the perpetuation of intimate partner violence (IPV) within the African community, in addition to more well-known factors such as ambivalent sexism and religiosity. Currently, it is the first experimental study into the hypothesis that internalized racism and endorsement of Black female stereotypes are not only strongly positively correlated with violence, but also act as significant positive predictors of individual attitudes towards Intimate Partner Violence alongside hostile sexism and religiosity. It was also hypothesized that there would be gender differences between scores, as male participants would score higher on the more overtly antagonistic measures (hostile sexism and Sapphire stereotype endorsement) while female participants would score higher on subjectively benign measures (benevolent sexism and Superwoman stereotype endorsement). The findings revealed that, while these hypotheses were largely supported by the results – with internalized racism being the strongest predictor of IPV attitudes amongst both genders – religiosity was unexpectedly found to be a negative predictor of IPV, especially in women. These results are discussed further in the literature. Keywords: Ambivalent Sexism, Stereotype, Sapphire, Superwoman, African, Intimate Partner Violence, Islam, Christianity, Religiosity
Integrated Investment Appraisal and Risk Analysis of an Undeveloped Oil Field Project in Libya
The Murzug region in Libya has an immense potential for oil production. As a result of the perishable nature of raw materials, it imposes a huge effect on the economy. The oil production plant will process high profit and help to the growth of the region. The aim of this study is to evaluate the economic potential of an undeveloped oil field in the Murzug Basin, south of Libya. The thesis aims to provide a financial model to serve as a guide for the future investment in oil field development program in remote area, the southern desert region of Libya. This thesis presents financial analysis study involving financial and sensitivity analyses. The study utilises a financial analysis approach to the problem of identifying and investigating the factors that control and effect the finances of the studied project. Thus, the study uses a financial and sensitivity analyses and draws on data obtained from an existing exploration activity and using it as an adjacent or an analogue to NC101 oil field and development project. This oil field is located south of Libya in the Murzug basin and is called the Al Shararah Field. I have personally made a site visit to the AL Shararah field and have interviewed several geologists, engineers and managers in order to collect accurate information and use them as reference to my thesis. The oil production will generate a positive NPV of 313 million usd dollars and an IRR of 17%, which means the project will generate enough profit from the owner’s perspective. The study also shows that the project will generate enough cash flow to pay its debt obligation. From the cash flow we can observe that the project will generate enough cash to cover its debts as the ADSCR and LLCR average ratio are 3.06 and 3.45 respectively. As for the sensitivity analysis we have identified six risky varaibles which are oil price, foreign inflation (USA) , tariffs per barrell , investment cost overrun, discount rate and the proportion of oil exported . The project was most sensitive to oil price, tariffs per barrel and foreign inflation. As for investment cost overrun the project was not sensitive towards it at all. The project's risks were evaluated using a Monte-Carlo simulation. The distribution of probability is used to show the uncertainty related to the key project variables. The simulation of Monte Carlo analysis was taken for oil prices, tarrif per barrel and foreign inflation .
Serial Mediation Mechanism of Service Innovative Behaviours in the Hotel Industry: Effects of Constructive Leadership, Psychological Safety and Engagement in Creative Works
This thesis aims to examine the influence of constructive leadership practices on the service innovative behaviors of hotel employees by a serial mediation system that treats employee psychological safety and employee creativity as mediators. Empirical data were collected from full-time frontline hotel employees in Antalya, Turkey. By using both convenience and judgmental sampling methods, this study included 357 hotel employees. The results provide empirical evidence for all suggested hypothesized associations. In particular, the findings display that psychological safety and engagement in creative work tasks play intervening roles (in the form of a chain) in the indirect influence of constructive leadership on employee perceptions regarding their service innovative culture. The current work provides practical contributions for hotel industry professionals who are in the treatment of implementing psychological safety and employee creativity, in order to establish innovative service culture in the hotel setting. This thesis is among the first studies to investigate a serial mediation model to analyze which constructive leadership practices influence their innovative service culture.
Dynamics Analysis of Viscoelastic Sandwiched Structures Integrated with Aluminum Sheets by Using Finite Element Method
Passive vibration attenuation of modern mechanical structures is one of the most essential technologies applied to the arsenal of modern mechanical structures. In this thesis, dynamics analysis is performed on viscoelastic (VE) beam and plate sandwich structures. The proposed structures are composed of a VE core and aluminum face sheets as the substrate layers on both sides of the structure. The small-strain VE material is modeled based on the complex constant moduli model. In the modal analysis, the model effective mass analysis is performed to investigate its dominant mode shape and its sweet spot at resonance. Then, in the harmonic analysis, the resonance frequency is obtained to evaluate the performance of the VE sandwich structures via the maximum deformation. A comparison between the results of an analysis of viscoelastic sandwiched structures with subsequent done using FE models. A numerical application is accomplished to develop the integral shear finite element and modal assembly of the stiffness element and mass element established according to strain energy and the Hamilton principle. The harmonic analysis is done using ABAQUS® software with both C3D20RH®, CPS8R where C3D20RH indicates a 3- D element with 20 nodes with reduced integration technique and hybrid formulation and CPS8R indicates 2-D plane strain with eight nodes with reduced integration technique, the results are compared against analytical solutions form the literature, a parametric study is done on the beam’s core thickness to study the effect on the damping characteristics of the beam, the results showed that the modal developed in MATLAB® achieved the least error compared to the analytical solution from the literature and then comes the Abaqus® software solution, also the parametric study showed that the natural frequency of the beam does not change with the increase of the core thickness, however, the loss factor is directly proportional to the thickness of the viscoelastic layer of the beam.

An Assessment of Undergraduate Students' Self-Regulated Online Learning Status in Emergency Remote Learning Period: An Example of EMU Faculty of Education
The emergence of the Coronavirus (Covid-19) pandemic has seriously affected education as it has affected many diverse fields around the world. As a result of this condition, many educational institutions made a quick transition to emergency remote learning, hence lessons were pursued online. As a result of this, students took their courses online in this process. The concept of self-regulated online learning has become an important concept during the emergency remote learning period. The aim of this thesis is to examine the self-regulated online learning status of undergraduate students studying at the Faculty of Education, Eastern Mediterranean University during the emergency remote learning period. The study was conducted as a quantitative research. For data collection tool, the “Self-Regulated Online Learning Questionnaire (SOL-Q)” developed by Jansen, Van Leeuwen, Janssen, Kester, and Kalz (2017), which was later adapted into Turkish by Yavuzalp and Özdemir (2020) was utilized. As a result of this study, it was determined that the general status of students' selfregulated online learning is good. In addition, the findings show that based on the subdimensions the self-regulated online learning status of students in respect to their metacognitive skills and time management is average; while environmental structuring, persistence and help seeking are good. In addition, when the self-regulated online learning status of the students were examined in terms of students with and without previous online learning experience, it was determined that their status was good in both groups. In other words, it was revealed that previous online learning experience did not generally make a difference on students' self-regulated online learning status. When the online learning experiences of the students were compared in terms of sub dimensions, it was seen just in the time management sub-dimension, the students who had previous online learning experience were in good condition, while the students who were inexperienced in online learning could be described as average. Except for the time management sub dimension, there was not detected any noticeable difference between the two groups (with and without online learning experience).
The Effects of Strategic Orientation on Mass Customization Capacity in Iran: The Mediating Role of Intellectual Capital
This study attempts to explore how Entrepreneurial Orientation (EO), Customer Orientation (CO) and Technology Orientation (TEO) affect Mass Customization Capacity (MCC) where the Intellectual Capital (IC) is considered as a mediating variable in this model. Considering that MCC equips companies with the agility, integration, and resource flexibility needed to thrive in a dynamic business landscape, this is the first study which aims to contribute to the dynamic capability theory and resource-based view by developing new conceptual model which incorporates IC as a competitive resource of the firms. This is also the first study that aims to develop a conceptual framework by adding TEO as a key dimension of strategic orientation in order to improve MCC. While prior studies have explored the independent effects of these elements, this work unveils how a firm's strategic direction can influence the effectiveness of its intellectual capital in bolstering its ability to deliver customized products. This novel framework provides deeper insights into how firms can strategically leverage their intellectual assets to achieve success in the dynamic landscape of mass customization. Cross-sectional data were collected from 175 Iranian manufacturing firms. The Confirmatory Factor Analyses (CFA) is used to check the validity of the multiple-item measures and Structural Equation Modelling (SEM) is applied to test the research hypothesis. The results indicated that EO, CO and TEO have a positive and significant effect on MCC. It is also found that IC partially mediates the relationships among all dimensions of strategic orientation and MCC. Our findings suggest that a company with higher intellectual capital can improve MCC by choosing the best type of strategy according to the industry in which they are active. Insights from findings also enable policymakers to design policies that encourage innovation in production processes and technologies, investing on research & development in relevant technologies or infrastructure projects that support efficient MC logistics and create regulations that protect consumer data and encourage sustainable practices within MC processes.

Modernism Through the Lens of Jacques Tati’s Playtime and Jacques Lacan’s Modules on the Structure of the Psyche
The modernist era brought forth new forms and designs that ignored any tradition, with architecture at the forefront of change, especially post World War II. But with these changes came a dismissal of human needs, and a systemization of human beings within the built environment. One excellent example that examines the failings of Modern Architecture is “Learning from Las Vegas” which concurs that the modernist approach to architecture, which prioritized functionality and efficiency, led to an environment that failed to meet the needs of its users Venturi, et al. (1972). Modern Architecture's impact on the human psyche is examined, furthermore, through the lens of Jacques Tati's Playtime and Jacques Lacan's three orders. The conceptual background of Modern Architecture is delved into, with the focus of its focus on efficiency, functionality, and order, demonstrating how the quest for order dismissed the human needs’ importance, leaving the individuals who willingly conformed to be lost in a sea of cubicles made of concrete and steel. These willing conformists are examined and understood through William H. Whyte’s book the Organization Man; hence, transitioning from Modern Architecture to Psychology. According to Lacan, three orders govern our perception of the world and are the recipe to the human psyche; these orders are: the Imaginary Order deals with the realm of images and perceptions, the Symbolic Order with language and cultural symbols, and the Real Order with the inexplicability of complexity of the human experience due to the insufficiency of the human language. The study concludes with the importance of integrating the three orders into architectural design, emphasizing the significance of considering the human psyche in Modern Architecture. This study enriches our understanding of modernism and highlights the crucial role of the psyche in architecture.

Biomimicry: A Tool to Achieve Sustainability in Interior Spaces
Nowadays the world is facing serious environmental problems such as global warming, pollution of air, water and soil, floods and droughts. A big part of these problems is caused by unconscious and excessive consumption of world resources by human beings. The building industry in general has a major role in a lot of environmental problems. For this reason, it is very important that the architects and interior architects adopt more environmentally friendly and sustainable design strategies to reduce these problems. Sustainability in general can be described as meeting or satisfying the needs of the current generation without diminishing or compromising the ability of future generations to meet their own needs. The concept of sustainability is very important in interior architecture as well. To ensure sustainability in interior spaces, it is first necessary to know the interiors with all their components, to know the expectation of sustainability in the interiors, and perhaps most importantly, to use a method that can create this. This is where biomimicry comes into play. The biomimicry method offers one of the most effective methods on the path to sustainability. The reason why biomimicry is powerful in terms of sustainability is that it derives its power from nature and the ability of natural organisms to survive for millions of years. This study has two main aims. The first aim is to determine what the environmental sustainability considerations in design of interior components are and to examine how biomimicry can help to achieve sustainability in interiors. As the first step of the study the sustainability requirements for various interior components and biomimicry design examples in the issues related to the interior architecture are searched. Then, a guide has prepared to be used by the interior architects where briefly the requirements to have sustainable interior components and examples of biomimicry designs that can help to achieve those goals are compiled. The study tends to create a tool to help interested interior designers in achieving more sustainable interior environments and to increase the use of biomimicry in interior architecture.

Türkiye’nin İstanbul Sözleşmesi’nden Çekilmesinin Çevrim İçi Haber Medyasında Temsili: Bir İçerik ve Eleştirel Söylem Analizi
Bu yüksek lisans tezi, ideolojik görüşü birbirinden farklı olan çevrimiçi gazete ve haber mecralarında Türkiye’nin İstanbul Sözleşmesi’nden çekilmesinin nasıl temsil edildiğini incelemektedir. Bu amaçla ideolojik görüşü farklı olan ana akım gazeteleri, Hürriyet, Sabah ve Yeni şafak, alternatif haber portalları (Bianet, T24) ve hak örgütleri (Kadın Cinayetlerini Önleyeceğiz Platformu ve Kaos GL) haber içerikleri ve söylemleri açısından değerlendirilmektedir. İlk olarak içerik analizi ile, ana akım gazeteler, ikinci olarak eleştirel söylem analizi ile haber portalları ve hak örgütlerinin haberleri ele alınmaktadır. İçerik analizinde; haberlerin tarihlere göre dağılımı, gazetelerin konuya karşı tutumları, haberlerin tonu, haberlerdeki politik figürler, referans/kaynak gösterimi, fotoğraf kullanımı, haber uzunlukları ve haberi özetleyen kelimeler olmak üzere farklı kategoriler tanımlanmıştır. Eleştirel söylem analizi bölümünde ise Van Dijk’in analizi metodu kullanılmıştır Haberler makro yapı içerisinde: tematik ve şematik, mikro yapı da ise; cümle yapısı, bölgesel uyum, sözcük seçimleri ve haber retoriği açısından irdelenmektedir. İçerik ve söylem analizinde farklı haber mecralarının ele alınmasının nedeni ortak noktaları bulunan iki analiz yönteminde, aynı şeyleri tekrarlamaktan kaçınmaktır. İçerik analizinde çevrimiçi ana akım gazeteler, söylem analizinde ise çevrimiçi alternatif haber platformları ve hak örgütleri çalışmanın örneklemini oluşturmaktadır. Çalışmanın örneklemi, 1 Mart – 31 Temmuz 2021 tarihleri arasındaki İstanbul Sözleşmesi’nin feshi ile ilgili en yoğun tartışmaların olduğu zaman diliminden derlenmiştir. Çalışma, analizler doğrultusunda siyaset ve medya ilişkisini ortaya koymak ve gazetelerin ideolojik yansımalarına ayna tutması bakımından önemlidir. Çevrimiçi haber medyasında feshi kararının ardından, sözleşme karşıtı ve yanlısı birçok haber yayınlanmıştır. Gazetelerin özellikle haberler başlıklarından yola çıkarak, işlenen tema ve kullanılan söylemlerin ideolojik çerçevede şekillendiği sonucuna varılmıştır. İstanbul Sözleşmesi medyada politik olarak temsil edilmektedir. Yeni medya ve hak örgütü platformları arasında, haberde kullanılan; ton, dil ve uslup konularında farklılıklar vardır. İçerik ve söylem analizi neticesinde bu farklılıklar çalışmada makro ve mikro ölçekte sunulmuştur. Anahtar Kelimeler: İstanbul sözleşmesi, temsil, ideoloji, yeni medya, şiddet
Uluslararası İlişkilerde Feminist Politikalar: İsveç Örneğine Eleştirel Bir Bakış
2014 yılında İsveç’te yapılan genel seçimlerin ardından kurulan, kendini feminist olarak tanımlayan koalisyon hükümeti, uluslararası ilişkilerinde toplumsal cinsiyet eşitliğini gözeten 3R kuralı (Rights, Representation, Reallocation) gereği haklar, temsiliyet ve kaynakların yeniden tahsisinde feminist bir yaklaşımla, kadınların ve kız çocuklarının sesi olacağını ilan etti. Bu yeni siyaset modeli dünyada hem heyecana neden oldu hem de kuşku ile karşılandı. Dünya nüfusunun yarıdan fazlasını oluşturan kadınların, toplumun savaş ve çatışmaların olumsuz sonuçlarından en ağır şekilde etkilenen kesimlerinden birisi olarak, müzakere masalarında yer alması gerektiği feminist kuramcılar tarafından yüksek sesle dillendirilirken, İsveç’in yaptığı bu açılım feminist uluslararası ilişkiler teorisi ve pratiği açısından çok önemli bir yere sahip oldu. Feminist uluslararası ilişkiler politikaları küresel adaletsizlik ve eşitsizliklerle mücadele dahil olmak üzere, çevre ve iklim krizi ile mücadeleden ve küresel açlıkla mücadeleye, ekonomik güvenliğin tesisinden tüm kesimlere kaliteli eğitim sağlamaya, geniş bedensel ve psikolojik sağlık politikalarından, kapsamlı bir esenlik hali oluşturmaya yönelik müdahalelere kadar birçok alanla ilgili planlamaları ve uygulamaları içermektedir. Bu siyaset devletin değil bireylerin güvenliğine öncelik verir. Feminist uluslararası ilişkiler politikaları, toplumsal cinsiyet eşitsizliğinin, LGBTİ grupların dışlanmasının, beyazların üstünlüğünün, ırkçılık, ataerkillik gibi baskı ve dışlama pratiklerinin üstesinden gelinmesini ilke edinir. Feminist uluslararası ilişkiler politikaları küresel çapta kapsamlı barış ve güvenliğin sağlanması hedefi ile oluşturulur. Bu çalışmanın amacı feminist uluslararası ilişkiler teorilerine odaklanılarak, İsveç’in 2014 yılından başlayarak dış siyasetteki uygulamalarını değerlendirmektir. Bu değerlendirmede eleştirel bir yaklaşımla ilk olarak İsveç’in göçmen ve mülteci politikalarına, ikinci olarak iklim ve çevre politikalarına, üçüncü olarak ise güvenlik ve savunma politikalarına odaklanılmıştır. Ayrıca İsveç’in 2022 yılı sonrasında resmi olarak feminist uluslararası ilişkileri terk ettiğini açıklaması da değerlendirme konusu yapılmıştır. Anahtar kelimeler: Feminist Uluslararası İlişkiler, Feminizm, Uluslararası İlişkiler, Toplumsal Cinsiyet, İsveç.
Investigating the Second Language (L2) Writing Strategies of University Students with Different First Languages (L1)
The aim of this study is to investigate the writing strategies employed by university students from diverse first languge (L1) backgrounds when writing in English (L2), highlighting the potential influence of L1 on L2 writing performance. The study was conducted amongst ten participants with five different L1s, those being Arabic, French, Turkish, Russian and English. The participants were all Freshman university students at Arkın University of Creative Arts and Design (ARUCAD) in North Cyprus, taking the mandatory SOFL102 course for all students regardless of their level of English. The data was gathered through a questionnaire, think-aloud procedures and a semi-structured restrospective interviews. During the think-aloud procedures, participating students were first required to write an academic argumentative essay and then a short story. The findings showed that regardless of the L1 the participants had, they generally did not use writing strategies when writing in their L1. This could be due to their confidence in their native language level and the type of task, as well as their unfamiliarity with the writing strategies in L1. In L2 writing, however, students with different L1s, regardless of which language they spoke, generally preferred to use various writing strategies in pre, while-, and post-writing stages. They reported that they used mostly ‘planning’ and ‘brainstorming’, which are cognitive and metacognitive strategies. As regards the use of L1 knowledge and skills to facilitate the L2 writing process, using their L1 was generally not preferred as a writing strategy. The participants reported that the usage of their L1 while writing in L2 caused issues for them such as making them feel like they were losing their English knowledge or focusing too much on translations. This study focused on writing strategies and writing skills. Further research can be done focusing on other skills such as reading, listening and speaking. Also, a similar study can be conducted over a longer period of time than the duration of this current study. Keywords: first language (L1), second language (L2), writing strategies
Retail Demand Forecasting using Machine Learning Algorithms
Understanding how to forecast a product's sales and demand is crucial for businesses that sell goods. Knowing how much demand will be in a given time gives them many benefits and gains. Many methods have been developed and used for demand forecasting from past to present. If we divide the methods used into two, traditional and machine learning methods are used for demand forecasting. We can say that traditional methods have left their place to machine learning due to less and slow data processing. Machine learning methods have the ability to process a lot of data faster and analyze the data it uses and provide a more accurate prediction by identifying hidden patterns in the data. The problem here is that there is no one "onesize-fits-all" prediction algorithm. Typically, demand forecasting features consist of several machine learning approaches. Therefore, the choice of machine learning models depends on many factors such as business goal, data type, data quantity and quality, forecast time. Therefore, the main problem here is to determine which algorithm will be used with which parameters. In this study, different machine learning methods and parameters was used and compared to select the most suitable machine learning algorithm and parameters according to the selected data set and provide more accurate predictions. Algorithms such as time series, linear regression, random forest was studied and external factors such as seasonal, regional and economic factors was used as parameters. The algorithm with the best results will be chosen from models with or without external factors. Keywords: Machine Learning, Demand Forecasting, Regression, Time Series
Developing Data Envelopment Analysis Model for Performance Evaluation of Green Supply Chain Management
In recent times, there has been a growing concern regarding environmental issues. This has resulted in increased pressure on companies and producers from government regulations, while also striving to maintain customer satisfaction by addressing environmental concerns. Green Supply Chain Management (GSCM) has emerged as a means to enhance efficiency and reduce environmental impact for firms collaborating with clients and suppliers. GSCM encompasses various aspects such as green purchasing, design, manufacturing, distribution, packaging, marketing, and reverse logistics within supply chains, to improve environmental performance. The use of nonparametric models, specifically Data Envelopment Analysis (DEA), has been prevalent in assessing the efficiency and proficiency of supply chains as decisionmaking units (DMUs). However, the earliest research on efficiency fulfilment in GSCM has not thoroughly explored the combined effect of economic and environmental factors, such as service level, CO2 emissions, and supply chain size (arcs), on the overall efficiency of the supply system. These principles are crucial as they can impact a manager's capability to accurately evaluate the performance of a green supply chain. Therefore, it is imperative to evaluate GSCM efficiency using DEA models while incorporating green principles to identify efficient DMUs and potential DMUs that can be improved with less cost and effort. This study aims to address this research gap by developing a benchmark approach to identify efficient DMUs and potentially efficient DMUs, which can be enhanced through minor adjustments. The study utilizes DEA standard models to determine benchmarks and potentially efficient DMUs and modifies their inputs to achieve an efficient status. Additionally, the impact of green elements on the efficiency of DMUs is assessed using Tobit regression analysis pre and post adjustment. Pragmatic outcomes obtained from the case study demonstrate the practicality of the proposed procedure in prioritizing potential DMUs for modification.

Underwater Image Enhancement using Fusion of Different Techniques
Underwater environment is potentially rich for scientific research and explorations, but it is challenging to capture the image of the underwater environment due to light absorption and scattering effects of water. In this research, white balance algorithm is employed to recover the lost color information and multiscale image fusion is applied to the features of gamma corrected and sharpened image for dehazing the underwater image and improve the contrast. This thesis proposes an approach that enhances color correction with Histogram Equalization (HE) and applies Contrast Limited Adaptive Histogram Equalization (CLAHE) to sharpened image to further improve the details of the underwater image. The UIEB and SQUID datasets are used which include underwater scenery with fish, coral reefs, divers, underwater structures and shipwrecks. The application of the multiscale image fusion with proposed algorithm achieves to balance the distorted colors of underwater image and enhances fine details and contrast to improve image quality. Keywords: underwater image enhancement, color compensation, multiscale image fusion.

Multi-Beam Near Field Focusing Characteristics of Microstrip Patch Antenna Array
Several modern-day antenna applications require the radiated fields to be focused at a predetermined point away from the antenna to perform different tasks, such as sensing, testing, charging, diagnosing, and treatment of different medical conditions. In this thesis, a thorough study has been made to investigate the characteristics of near-field focusing. In many applications, along with focusing the radiated fields at a focal point, it is also required to move that focused beam to scan a specific region i.e., usually carried out either electronically or physically by changing the position of the antenna array. The thesis proposes a robust mechanism to move the focused beam at single and dual focal points to improve the scanning properties of the antenna array. The proposed mechanism does not depend upon any external phase shifter circuit or changing the position of the array for focusing and scanning the focused beam. The movement of the focused beam is achieved as a result of introducing extra transmission lines to the scanning axis of the array. Antenna designs for single-focal and dual-focal points are analyzed using MATLAB and CST simulation software. The simulation results show that the proposed designs work efficiently as the movement of the beam is controlled by the change in frequency. Furthermore, in the case of dual focal point near field focused antenna array, there is a significant increase in the scanning distance as compared to the single focal point. The proposed mechanism results in an increment in scanning distance of around 53%. The proposed designs can be used in applications such as RFID, Non-destructive industrial inspection and testing, and wireless power transfer, where the focused beam is to be directed at a point in the near-field and the scanning of the focused beam is required as well. Keywords: microstrip patch antenna array, near-field focusing, parasitic patch, hyperthermia, beam scanning.
