تعتبر الابنية العالية من مميزات المدن العالمية، اذ تعبر عن قوتها الاقتصادية وتعطيها رمزية تميزها على الصعيد المحلي والعالمي، اذ تخلق الابنية العالية مدن مستدامة وجاذبة للعيش والعمل ومزدهرة إذا ما خططت وصممت بشكل جيد، اذ يصل تاثيرها على السياق المجاور لها وفي بعض الاحيان على المدينة ككل، لذلك كان لابد من دراسة المؤشرات التخطيطية للابنية العالية في السياق الحضري. على وفق ذلك اعتمد البحث كمحور عام مفهوم الابنية العالية في السياق الحضري ، وقد تعددت الجوانب التخطيطية للابنية العالية بصورة عامة مع تنوع وتعدد التوجهات المعاصرة, واهتم البحث بالابنية العالية المفردة في السياق الحضري كمحور خاص, اذ تم استعراض العديد من الدراسات بهدف تحديد الفجوة المعرفية التي ادت الى بروز عدة مشاكل بحثية من حيث تعدد وتنوع الجوانب التخطيطية, , وبذلك تبلورت مشكلة البحث التي ركزت على اكثر النواحي نقصاً في الدراسات السابقة والمتمثلة قصور المعرفة المنظمة الشاملة للمؤشرات التخطيطية الخاصة بعلاقة الابنية العالية المفردة مع السياق الحضري وبما يرتبط بالواقع المحلي, وبذلك تحدد هدف البحث بطرح المعرفة الشاملة الاكثر تنظيماً  ووضوحاً للمؤشرات التخطيطية للابنية العالية المفردة في السياق الحضري وبما يرتبط بالواقع المحلي على وجه الخصوص, وقد استوجب تحقيق هذا الهدف اعتماد منهج تحليلي وصفي للدراسات والتجارب التطبيقية المرتبطة بالموضوع ضمن هيكل تسلسل بخطوات اساسية للبحث, تمثلت الخطوة الاولى ببناء اطار نظري شامل يعرف الابنية العالية المفردة في السياق الحضري , و تبلور في مفردتين اساسية هي: مقومات الابنية العالية, الجوانب التخطيطية للابنية العالية في السياق الحضري . وركزت الخطوة الثانية على تطبيق مفردات الإطار النظري على نماذج منتخبة من المشاريع المحلية، ومن ثم تحليل نتائج الدراسة العملية ومناقشتها، ليتم بعدها طرح الاستنتاجات النهائية.The tall buildings play an important role in giving a distinctive image for the city. It is one of the most important features of the big cities, as it enhances its value and reflects its urban economic and technological development, as well as the city's image for the local and the international levels. If they have been designed and planned well in its urban context. The tall buildings contribute to create a vibrant, prosperous, sustainable and attractive city for living and working, farther more optimize the energy and land use, providing public spaces, streets and spaces of social interaction as well as employing high technology, especially in infrastructure. The research adopted the tall buildings in the urban context as a general concept. The multiple contemporary trends of planning considerations for tall buildings in the urban context and the lack of a comprehensive picture resulted the special concept of the search "Tall buildings in the urban context ". Which was done by reviewing several international, Arabic and local studies for identifying the knowledge gap that led to the emergence of a research problem in terms of the multiplicity and diversity of planning aspects. Most of the international studies indicated them in general and selective, while the thesis was implicit and unclear in the Arab studies, and there were lack in local studies. The research problem, which focused on the most critical aspects of the previous studies, was characterized by the lack of comprehensive knowledge of the planning and designing indicators of the tall buildings relationship with the urban context and the local reality. For that objective goal of the research determined to provide the most comprehensive and clear knowledge of the planning and designing indicators of tall buildings in the urban context and in particular the local reality. The achievement of this goal necessitated the adoption of a descriptive analytical approach to the relevant studies and practical experiments within the structure of a sequence of basic steps for research. The first step was to construct a comprehensive theoretical framework that defines tall buildings in urban context. That resulted three aspects: general analytical aspects of tall buildings, planning considerations for tall buildings in the urban context، the second step focused on applying the concepts of the theoretical framework to selected models of local projects and analyzed them then discussion the results of the practical study, after that presenting the conclusions of the application within the local reality

The Impact of Cognitive Biases on The Investment Decision of Individual Investors: The Role of Risk Propensity

This study investigates the impact of cognitive biases on individual investors' investment decisions using the mediation role of risk propensity. Data was collected from 320 investors with a minimum of one year of experience and over a 90-day time frame. A self-administered questionnaire was used, and statistical analysis was performed using smart PLS and SPSS. The results showed that cognitive biases have a positive impact on individual investment decisions, with an indirect effect supporting the meditation model between cognitive biases and investment decisions. The indirect effect of risk propensity also positively influences cognitive biases and investment decisions. This study contributes to the mediating role of risk propensity and validates it from an individual perspective, allowing for better understanding of the relationship between cognitive biases and investment decisions. The outcomes and implications of this research are relevant for behavioral finance-related research and can help individual investors, financial institutions, and governments better understand the role of investors' behavior in the stock market

A Distance Based Method for Solving Multi-objective Optimization Problems

A new model for the weighted method of goal programming is proposed based on minimizing the distances between ideal objectives to feasible objective space. It provides the best compromised solution for Multi Objective Linear Programming Problems (MOLPP). The proposed model tackles MOLPP by solving a series of single objective sub-problems, where the objectives are transformed into constraints. The compromise solution so obtained may be improved by defining priorities in terms of the weight. A criterion is also proposed for deciding the best compromise solution. Applications of the algorithm are discussed for transportation and assignment problems involving multiple and conflicting objectives. Numerical illustrations are given for the proposed model

In Silico Tools for Analysis of Single-Nucleotide Polymorphisms in the Bovine Transferrin Gene

Dairy cattle with a high milk yield are susceptible to many infectious diseases, such as mastitis. Subclinical mastitis (SCM) is the most prevalent form of mastitis that predominantly affects animal health, and causes adverse effects on the quality and quantity of milk. In dairy animals, subclinical mastitis often remains undetected, as no gross changes in udder characteristics are visible. In the present study, 135 Holstein Friesian dairy animals were selected and screened as healthy (n = 25) and mastitic (n = 110) based on diagnostic tests such as the California mastitis test, pH, electrical conductivity, and somatic cell count. In this study, the somatic cell count was used as a gold-standard test in differentiating subclinical mastitis animals from healthy ones. The present study was carried out to study polymorphisms in the bovine transferrin gene in cows (with subclinical mastitis and healthy). For the early detection of resistant/or susceptible animals, a useful marker could be provided by the detection of single-nucleotide polymorphisms (SNPs) in the transferrin gene, which are often associated with mammary innate immune response. The sequencing results revealed three nucleotide substitutions: two transversions (230 A \u3e C, 231 C \u3e A) and one transition (294 A \u3e G) in susceptible cows as compared to disease-free subjects. The nucleotide variations at position 230 (GAC \u3e GCA) and 231 (GAC \u3e GCA) were nonsynonymous, and corresponded to an amino acid change from aspartic acid to alanine; whereas at position 294 (GAA \u3e GAG), the mutation was synonymous. In the present study, many in silico tools were taken into consideration to determine the effect of SNPs on protein structure and function. The PROVEAN tool found the amino acid substitution to be neutral and deleterious. PolyPhen-2 revealed the amino acid variations at positions 320 and 321 to most likely be damaging; and at the 341 position, the variations were benign. The I-Mutant and MUpro tools found that the protein stability decreased for nonsynonymous variations. The SIFT tool revealed the protein function was likely to be affected in nonsynonymous variations, with no change in the case of synonymous ones. Phylogenetic analysis of the bovine transferrin gene revealed a close relation of the CA allele with the Bos taurus transferrin, while the G allele was closely related to a cross of Bos indicus × Bos taurus serotransferrins, followed by the Bison bison transferrin. The least relation was shown by both alleles to Capra hircus, Ovis aries, and Bubalus bubalis

Empirical Study of the Impact of Brand Name on Market Performance through Sustainable Competitive Advantage and Brand Loyalty as Moderator in Pakistani Context

This research examined the impact of sustainability based marketing asset (e.g., brand name) on market performance through the sustainable competitive advantage and with the moderating effect of brand loyalty. The data was collected from 360 respondents who were customers of hotels/restaurants, on likert scale from 1= strongly disagree to 5 = strongly agree that was used to empirically test the hypotheses. Primarily the current research is carried out to know the relationship among the brand name, brand loyalty, sustainable competitive advantage and market performance in Pakistani hotel/restaurants industry. The current research is conducted through questionnaire-based survey from individuals who were the customers of hotel/restaurants in Pakistan. Structural equation modeling technique is adopted through AMOS version 23. The results of the research show that sustainable competitive advantage partially mediates the relationship between brand name and market performance and brand loyalty moderates the relationship between sustainable competitive advantage and market performance. The results of this research are beneficial for the service industry and help the marketers in formulating their marketing strategies to attract the more and more customers toward service industry. In addition, according to researcher knowledge sustainable competitive advantage was not studied as a mediator between sustainability-based marketing asset (e.g., brand name) and market performance and brand loyalty as a moderator between sustainable competitive advantage and market performance before this study

An area-optimized N-bit multiplication technique using N/2-bit multiplication algorithm

A unique design for an optimized N-bit multiplier is proposed and implemented which utilizes a modified divide-and-conquer technique. The conventional technique requires four N/2-bit multipliers to perform N-bit multiplication, whereas the proposed design uses only one multiplier module in hardware to perform the functionality of four modules. It uses Dadda algorithm in its multiplier module. It has been implemented using Verilog HDL, and a good accuracy of results was observed in simulations which effectively verify its functionality. Design was also synthesized on various FPGAs including Spartan 3E, Virtex-5 and Virtex-7. Performance summary, after place and route, showed that the proposed approach significantly reduces hardware utilization. Furthermore, the proposed design is almost 75% more efficient in terms of resources utilization and operating frequency as compared to the conventional design
