Generalized inequalities on warped product submanifolds in nearly trans-Sasakian manifolds

In this paper, we study warped product submanifolds of nearly trans-Sasakian manifolds. The non-existence of the warped product semi-slant submanifolds of the type $N_\theta\times{_{f}N_T}$ is shown, whereas some characterization and new geometric obstructions are obtained for the warped products of the type $N_T\times{_{f}N_\theta}$. We establish two general inequalities for the squared norm of the second fundamental form. The first inequality generalizes derived inequalities for some contact metric manifolds [16, 18, 19, 24], while by a new technique, the second inequality is constructed to express the relation between extrinsic invariant (second fundamental form) and intrinsic invariant (scalar curvatures). The equality cases are also discussed.Comment: 16 page

The Impeding Drivers of Risks at Private Higher Education Institutions in Jordan: An Analytical Approach

This study provides an in depth assessment of the main drivers of risk impeding private higher education institutions in Jordan. The study adopts an analytical approach that incorporates reviewing available literature and conducting interviews and discussions with some shareholders and board of trustees' members in addition to faculty members and students of private universities. The analysis revealed that although private universities in Jordan are making progress and provide important contributions to the economy, however, they face important strategic and operational risks in addition to other compliance, financial and reputational risks. These risks include educational delivery systems, quality of academic programs, executive management, competition, and utilization of new technologies, compliance with accrediting agencies, financial issues, societal perception, students' violence, and demographic challenges. The study concludes that private universities need to place risk management plans to effectively deal with the all risk indicators analyzed in the study. Recommendations on how to implement a risk management plan are also presented and highlighted

A study of academic achievement, socioeconomic status, intelligence, gender and their relations to general and academic self-concept of twelfth grade students in the United Arab Emirates

This study is based on a multifaceted model of self-concept and aimed to explore the intricacies of the multidimensional nature of self-concept and its relationship to students' academic achievement, socioeconomic status and their intelligence. Sex differences in various facets were also investigated as a major concern of this study. The subjects of this study were 157 boys and 177 girls, drawn from 12th Grade students from five educational zones in the United Arab Emirates. Three instruments were used to assess students' self-concept. The Self-Description Questonnaire (SDQ) was utilised to assess students' self-concept of Arabic language, chemistry, mathematics, peer relations, parent relations, physical ability and physical appearance. The Brokeover Self-Concept of Academic Ability Scale (SCAA) was administered to assess students' self-concept of general academic ability. Students' general self-concept was measured by the Coopersmith Self-Esteem Inventory. The Raven Progressive Matrix Test assessed students' general IQ and Socioeconomic Status (SES), measured by the sum of four demographic variables related to parents' education, occupation, housing and income. Students' achievement level was assessed by the mid-term examination grades in Arabic language, mathematics and chemistry. The major statistical tools used were independent t-test, simple correlation, partial regression, stepwise regression and canonical correlation analysis. The findings of this study reveal that girls had higher self-concept of mathematics, chemistry, general academic ability and physical appearance and boys had higher self-concept of physical ability. No sex differences, however, were recorded in the areas of Arabic language, parent relations, peer relations and general self-concept. Furthermore, a significant low correlation was observed between IQ and some dimensions of selfconcept (mathematics, general and general academic ability). A weak association was found between students' socioeconomic status and their general and academic selfconcepts. The relationships between self-concept dimensions and each of IQ and SES were different for boys and girls. Students' achievement scores in mathematics and chemistry were strongly correlated with their self-concept in corresponding areas, but showed almost no correlatation with their non-academic self-concepts. A few recommendations are forwarded for further study and some implications are outlined at the end of this thesis

Hydrologic Evaluation of Surface and Subsurface Water in Highly Managed Watershed with Limited Observations

The risk associated with managing water resources (flood or drought) depends on the adequate operation of infrastructure facilities (e.g., dams) with in the river basins. However, one of the major challenges to develop and operate infrastructures to meet stakeholder’s goal is to generate accurate hydrologic information (e.g., streamflow) for ungagged (limited data/data scarce) river basins. This process usually requires spatiotemporal hydroclimatic information, such as precipitations, streamflow, and groundwater storage. Hydrological models are useful tools for investigating hydrological processes in data scarce river basins with limited hydrological measurements. The overall objective of this dissertation is to develop a modeling framework to improve surface and groundwater resources management in data scarce river basins, located in different parts of the world. This dissertation examines the improvements of the estimations, simulation, and evaluation of various spatiotemporal hydroclimate data for a river basin located in a semi-arid climate zone and poorly represented by actual observations. First, a modeling framework is developed and applied to investigate multiple bias removal techniques to improve the use of available gridded precipitation products in poorly gauged river basins; secondly, the study is extended to investigate hydrologic processes and to simulate streamflow for ungagged river basins using different precipitation data sources; and finally an integrated surface and groundwater modeling framework was developed to evaluate potential surface and groundwater resources in Tigris and Euphrates River Basin

Product Qualification And Performance Assessment Of HSRM Prestressed Concrete Railroad Ties Through Laboratory Testing

This study focuses on the performance assessment of prestressed concrete railroad ties made of a newly developed High Strength Reduce Modulus (HSRM) concrete. The HSRM material has been developed by researchers at the University of South Carolina laboratories. The HSRM material was originally considered as a high-performance concrete for highway bridge girders, but it was rejected because it shows very low modulus of elasticity. A current project at USC proposed to use this HSRM material in prestressed concrete railroad ties. The experimental tests during the material development phase of the project showed that the HSRM-HPC has a reduced Modulus of elasticity as much as 50 % compared to conventional high strength concrete. The hypothesis is that a more resilient concrete tie will better distribute the loads and delay the initiation of cracking. This work discusses the qualification of the new HSRM concrete tie according to the guidelines of the American Railway and Maintenance of Way Association (AREMA) requirements and assesses its performance by comparing its performance to the equivalent Standard prestressed concrete ties currently in use in order to validate the hypothesis. To this end, a number of prototype HSRM ties and Standard concrete ties have been fabricated at a major US concrete tie manufacturer and tested in the structures laboratories at the University of South Carolina. Conventional instrumentation, as well as state of the art laboratory instrumentation based on vision system, is employed in these studies. Experimental investigations have shown that the newly developed of HSRM ties not only satisfy the requirements of the design guidelines but also have shown superior structural performance to the Standard ties under static and cyclic load tests. The higher flexibility of the HSRM ties leads to normalized stress fields, reduced stress amplitudes in critical areas, and better post cracking performance and ultimate strength as compared to the Standard ties

Seısmıc Performance Improvement Of Steel Buıldıngs By Usıng Zıpper Braces

Ters V çaprazlar merkezi çapraz sistemlerin bir tipini oluşturmaktadır. Bu tür sistemlerin deprem performansı çoğunlukla birinci kat çapraz elemanların basınçta burkulmasına bağlıdır. Genellikle, şiddetli depremler altında bu sistemlerde yük tekrar dağılımı yeterli şekilde gerçekleşmemektedir. Literatürde bu problemin çözümü için fermuar tipi çapraz kullanımı önerilmektedir. Sunulan bu çalışmada, fermuar çaprazların değişik deprem kuvvetlerine maruz 3, 6 ve 8 katlı çelik binaların deprem davranışına etkisi incelenmiştir. Örnek binalar her yönde üç eşit açıklığa ve aynı kat planına sahiptir. Bu nedenle analizlerde iki boyutlu modeller kullanılmıştır. Mevcut yapıların yapısal davranışlarının iyileştirilmesinde tek ve çift fermuar çapraz uygulaması yapılmıştır. Yapıların analizinde doğrusal olmayan statik ve dinamik analizler gerçekleştirilmiştir. Dinamik analizlerde 1994 Northridge, 1999 Hector Mine ve 1999 Chi-Chi deprem kayıtları kullanılmıştır. Yapı yüksekliği boyunca fermuar çaprazların kullanımının yapıların deprem davranışı üzerinde önemli etkisinin olduğu, ayrıca, çapraz kullanımı ile mevcut yapıların göreli kat ötelenmesi ve yerdeğiştirme taleplerinde azalmalar olduğu görülmüştür
