This led to the development of key microwave components like klystrons, carcinotrons, and traveling wave tubes that enabled new radar and signals intelligence systems and helped spawn the electronics industry in the area after the war.","url":"https://www.slideshare.net/slideshow/secret-history-of-silicon-valley-rev-4-dec-09/2658658","datePublished":"2009-12-06 00:40:59

Valley, tracing the origins of entrepreneurship in the region back to World War II when Stanford Professor Frederick Terman established the Electronics Research Laboratory to develop electronic warfare technologies for the US military using radar and communications. This led to the development of key microwave components like klystrons, carcinotrons, and traveling wave tubes that enabled new radar and signals intelligence systems and helped spawn the electronics industry in the area after the war.<button type="button" class="Button_root__i1yp0 Button_primary__K25Gq Button_text__ZT_3O Button_small__sqsEx Description_less__BvWbY Description_hidden__a9QZJ"

OpenFlow 1.3+ supports master/slave roles to facilitate failover.\n\n- The Entity Ownership Service elects a master controller for each switch using strategies like first candidate or least loaded. It notifies of ownership changes.\n\n- Challenges include race conditions, switch connection flapping, partitioning, and scale.

Whether through the wisdom of Jnana Yoga, the healing of Ayurveda, or the tranquility of Nature, individuals can cultivate a path leading to deeper fulfillment and enlightenment. Dr. Shivam Mishra’s meticulous research emphasizes how these timeless traditions, when practiced together, create a holistic and transformative spiritual experience.\n\nBy integrating knowledge, health, and nature, we can embark on a profound journey toward discovering our true essence and the boundless spiritual potential within us all.Integrating Jnana Yoga, Ayurveda, and Nature for Spiritual Growth\n\nDr. Shivam Mishra’s research highlights the synergistic relationship between Jnana Yoga, Ayurveda, and Nature in deepening spiritual practice. Here’s how they integrate:\n\nSelf-Inquiry and Knowledge (Jnana Yoga): Enables one to seek ultimate truth and self-realization.\n\nHolistic Health and Well-being (Ayurveda): Ensures physical and mental purity, essential for spiritual elevation.\n\nConnection with the Universe (Nature): Provides an environment conducive to deep meditation and self-discovery.\n\nPracticing all three together fosters a harmonious and balanced spiritual journey, enhancing clarity, vitality, and enlightenment.Spirituality is an expansive and deeply personal journey that transcends religious boundaries, aiming to connect individuals with a higher consciousness, inner peace, and self-realization. It encompasses a range of practices, beliefs, and experiences that enable a deeper understanding of the self, existence, and the universe. Dr. Shivam Mishra has extensively researched and created a detailed presentation on the interrelation of Jnana Yoga, Ayurveda, and Nature in fostering spiritual growth. This exploration delves into these elements, unraveling their profound impact on human well-being and enlightenment.\n\nUnderstanding Spirituality\n\nAt its core, spirituality is the pursuit of a meaningful connection with something greater than oneself. It is not confined to religious practices but extends to mindfulness, ethical living, self-inquiry, and the cultivation of inner harmony. Spirituality allows individuals to transcend materialistic pursuits and embrace a holistic, balanced way of living.\n\nDifferent traditions interpret spirituality in various ways. Some perceive it as the realization of the divine, while others see it as self-actualization and ethical living. Regardless of the interpretation, spiritual practices generally focus on inner transformation, wisdom, and universal consciousness.","tags":["#spirituality","#yoga","#drshivammishra"],"url":"https://www.slideshare.net/slideshow/what-is-spirituality-by-dr-shivam-mishra-sir-pptx/275578243","userLogin":"directorycvietnam","userName":"directorycvietnam","viewCount":777},{"algorithmId":"4","displayTitle":"HEALTH10-Q4-PPT_Lesson 1 (Health Career).pptx","isSavedByCurrentUser":false,"pageCount":16,"score":0,"slideshowId":"275579113","sourceName":"LATEST","strippedTitle":"health10-q4-ppt_lesson-1-health-career-pptx","thumbnail":"https://cdn.slidesharecdn.com/ss_thumbnails/health10-q4-pptlesson1healthcareer-250212100813-9641bc10-thumbnail.jpg?width=600\u0026height=600\u0026fit=bounds","description":"Faith holds significant importance in many aspects of life:\n\nProvides Comfort and Hope: During challenging times, faith can offer solace and a sense of hope, helping individuals navigate difficulties with resilience and optimism.\n\nGuides Values and Morals: Faith often serves as a foundation for one's values and moral principles, guiding ethical decisions and behavior.\n\nBuilds Community: Shared faith can foster a sense of belonging and community, creating strong bonds among individuals who share similar beliefs.\n\nEnhances Personal Growth: Faith can inspire self-reflection, personal development, and a deeper understanding of oneself and the world.\n\nOffers Purpose and Meaning: Faith can give life a deeper sense of purpose and meaning, motivating individuals to pursue their goals and dreams with passion and determination.\n\nFaith's impact varies from person to person, but its influence on providing emotional support, ethical guidance, and a sense of community is often profound.

Many iterative methods for solving algebraic and transcendental equations is presented by the different formulae. Using bisection method , secant method and the Newton’s iterative method and their results are compared. The software, matlab 2009a was used to find the root of the function for the interval [0,1]. Numerical rate of convergence of root has been found in each calculation. It was observed that the Bisection method converges at the 47 iteration while Newton and Secant methods converge to the exact root of 0.36042170296032 with error level at the 4th and 5th iteration respectively. It was also observed that the Newton method required less number of iteration in comparison to that of secant method. However, when we compare performance, we must compare both cost and speed of convergence [6]. It was then concluded that of the three methods considered, Secant method is the most effective scheme. By the use of numerical experiments to show that secant method are more efficient than others.","tags":[],"url":"https://www.slideshare.net/slideshow/numerical-study-of-some-iterative-methods-for-solving-nonlinear-equation-pdf/275590207","userLogin":"DrAzizulHasan1","userName":"Dr Azizul Hasan","viewCount":18},{"algorithmId":"4","displayTitle":"Lecture Notes Microprocessor and Controller Unit2","isSavedByCurrentUser":false,"pageCount":36,"score":0,"slideshowId":"275715906","sourceName":"LATEST","strippedTitle":"lecture-notes-microprocessor-and-controllerunit2","thumbnail":"https://cdn.slidesharecdn.com/ss_thumbnails/lecturenotesmicroprocessorunit2-250216235649-e0287103-thumbnail.jpg?width=600\u0026height=600\u0026fit=bounds","description":"Lecture Notes - Microprocessor - Unit 2 - 8085 Pinout signal, Functional Block Diagram and Instruction Set\r\nDescription:\r\nWelcome to the comprehensive guide on Microprocessor and micro controller tailored for First year (Second Semester) B.Sc.
