Harbor UCLA Neuro-Radiology Case 8Surgical Neurology InternationalThis case report documents a 28 month old girl presenting with progressive ataxia and lower extremity weakness. Imaging reveals a heterogeneous posterior fossa mass with calcifications, hydrocephalus, and mass effect. Histopathology of the tumor shows a "small blue cell" neoplasm positive for synaptophysin and GFAP. The proliferation index varies within the tumor. The findings are consistent with medulloblastoma, the most common pediatric brain tumor of the posterior fossa.
A comparison of historical vs current instructional designClemson UniversityThis document compares historical and current instructional design strategies used in the manufacturing industry. It discusses pioneers in the field from the 1900s like Frederick Taylor who developed timed work instructions. Sidney Pressey created early teaching machines, while B.F. Skinner researched programmed instruction. W.E. Deming applied quality control methods and embraced instructional design. The document finds that while methods have impacted design and learning, approaches have changed little since Taylorism. It identifies future trends like inclusion of diverse perspectives and customized instructional materials.

Overview on nanotechnologyMohamed YaserMolecular manufacturing (MM) aims to precisely construct complex products atom-by-atom using mechanical chemistry and robotic assembly. Theoretical studies have shown it is possible to build molecular structures like diamond lattices in this way. A small robotic device called a fabricator could use supplied chemicals to manufacture nanoscale shapes and machines. Multiple fabricators could then be combined to create a personal nanofactory (PN) capable of building human-scale products within months. Once achieved, MM would allow highly efficient, precise, and inexpensive production through self-replicating nanofactories making both commercial and military applications very desirable.

While progress has been made, fully general human-level artificial intelligence remains an ongoing challenge being worked on by researchers.
Seddon j. basic helicopter aerodynamics [bsp prof. books 1990]Mohamed YaserThe document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
The 10 natural_laws_of_successful_time_and_life_managementMohamed YaserThe document summarizes the 10 natural laws of successful time and life management. It discusses how inner peace comes from aligning daily activities with core values. It provides a pyramid model showing the relationship between values, goals, and tasks. The laws discuss controlling events through planning, setting goals beyond one's comfort zone, and managing behavior by examining beliefs and needs. Behavior patterns reflect underlying beliefs, and negative behaviors are overcome by changing incorrect beliefs.
The 10 Natural Laws Of Successful Time And Life ManagementMohamed YaserThe document outlines 10 natural laws of successful time and life management according to Hyrum W. Smith. The three most important laws are:
1. Your governing values are the foundation of personal fulfillment. Identifying your core values through writing a "personal constitution" allows you to plan your time effectively.
2. When your daily activities reflect your governing values, prioritized in order of importance, you experience inner peace and avoid neglecting what matters most.
3. You control your life by controlling your time. Focus on identifying vital versus urgent tasks and spend maximum time on important priorities rather than what is simply urgent. Managing events according to your values leads to fulfillment.
Theory Of Wing SectionsMohamed YaserThis document discusses the development of a new type of battery that could revolutionize energy storage. It describes how the battery uses a solid electrolyte material that conducts ions quickly without using liquid electrolytes. This leads to a battery that charges faster, lasts longer and poses less risk of leaks or fires. The solid-state battery is expected to be commercially available within the next five years and could replace lithium-ion batteries in many applications.
F- 20Mohamed YaserThe Northrop F-20 Tigershark was a privately developed fighter aircraft intended to compete with the F-16 Fighting Falcon. It began flying in 1982 but failed to secure any orders due to the US relaxing restrictions on F-16 sales. While the F-20 had performance comparable to early F-16 models, its airframe was based on the older F-5 design with limited expansion capabilities. The last prototype is displayed at the California Science Center.

structure for aerospace engMohamed YaserThis document provides an introduction and overview of the structural design process for aerospace structures. It discusses that structural integrity is key to prevent failure, and the majority of accidents are due to structural material failure. The course will provide tools to properly design aerospace structures to ensure integrity. It notes that while aircraft structures have been the main focus, the techniques can be generalized to other structures like space structures. The structural design process is then outlined, with the goal being to ensure integrity while minimizing cost, often meaning weight. Key aspects of structural integrity are also defined.
Tutorial 2Mohamed YaserThis document provides a summary of basic MATLAB commands organized into sections:
1) Basic scalar, vector, and matrix operations including declaring variables, performing arithmetic, accessing elements, and clearing memory.
2) Using character strings to print output and combine text.
3) Common mathematical operations like exponents, logarithms, trigonometric functions, rounding, and converting between numeric and string formats.
The document demonstrates how to perform essential tasks in MATLAB through examples and explanations of core commands. It serves as an introductory tutorial for newcomers to learn MATLAB's basic functionality.
TutorialMohamed YaserThis document provides an introduction to using MATLAB for numerical methods in chemical engineering. It discusses how computers solve problems by breaking them down into linear algebraic systems that can be represented as matrix equations. While compiled languages like FORTRAN are efficient, MATLAB is better suited for education and small-to-medium projects because it is an interpreted language, allowing interactive use without needing to compile code. MATLAB handles tasks like input/output, variable naming, and graphics internally through pre-compiled routines.
1Mohamed YaserThis document provides a tutorial on basic MATLAB commands for creating, manipulating, and operating on vectors and matrices. It describes how to create vectors and matrices, change their entries, perform matrix multiplication and inversion, extract submatrices, and create special matrices like identity and diagonal matrices. Examples are provided to illustrate various commands like eye, inv, backslash, and how to input vectors, matrices, and create M-files for functions and scripts.
realitivistic relativity 2.0Mohamed YaserThis document introduces an alternative theoretical framework to Einstein's theory of special relativity called Realitivistic Relativity 2.0. It proposes that star systems and atomic systems are fundamentally similar, with stars behaving like protons and planets like electrons. The author derived mathematical relationships between celestial objects and their quantum counterparts with high accuracy. This work maps objects in star systems to particles in atoms and vice versa, challenging existing interpretations of physics. It aims to simplify and unite physics through reexamining data from first principles without preconceived theories.
Lec5Mohamed YaserThis document summarizes a lecture on forces and moments transmitted by slender members. It defines slender members as long, skinny structural elements like skis, golf clubs, and I-beams. It discusses axial forces that act along the member's axis, shear forces that act in the plane of the member's face, and bending moments. Sign conventions for these internal loads are also defined. An example is provided to demonstrate calculating the internal forces and moments in a beam by setting up free body diagrams at different points.
