...impact on development, insecurity Road remains a major problem that faces In addition to pain and suffering, road accidents cause the Morocco huge economic losses. According to a study by The International Bank for Reconstruction and Development (IBRD), the estimated cost of traffic accidents in Morocco is 2.5% GDP or 8 billion dirhams per year (2000 estimate). If current trends continue, this amount will reach 10.5 billion Dirhams in 2012. The number of fatalities projected to increase by 32% (for to about 4,964 deaths in 2012) After this brief introduction, as we all know we have a lot of causes like Carelessness, Lack of experience and licensing, Drunkenness …. That produces this phenomenon, ESPECIALLY THE ACCIDENT THAT ARE MADE BY BIG TRUCK 15 M LONG but what is the solution offer a limited end this problem in other way what are the solutions proposed by the Moroccan Minister of Equipment and Transport ? This report should be considered anon-exhaustive study of literature devoted to the problem definition, the different technical solutions, legal requirements which must meet these solutions and their potential effectiveness. Here’s some action plan that should be taken to decrease accidents caused by big trucks: For example 1 Mirrors The various types of mirror (proximity mirror, mirror angle) can eliminate a large Series of blind spots on the right and left front of the vehicle. The wide-angle mirrors can collect angles Dead, right and left sides, at a distance...

...Broken Mirror: The Mirror Neuron System and the Salience Landscape Dysfunction Pamela H. Crittenden University of Maryland University College The Mirror Neuron System and the Salience Landscape Dysfunction This paper will summarized and critique the important points discussed by Vilayanur S. Ramachandran and Lindsay M. Oberman in the article “The Theory of Autism”. Support and expansion of the ideas presented will be discussed. Several points in the article will be evaluated. Two theories that were prevalent during their studies to help explain and or determine the cause of Autism were the Mirror Neuron Dysfunctions and Disrupted Salience Landscape Theory. To begin it is important to define what is meant by Autism. It is a genetic disorder that plagues a small portion of Americans. Children diagnosed with Autism are unable to carry on normal conversations and tend to remove themselves from any chance of social contact. Although they may experience different types of emotions such as fear and pleasure they also experience poor language, lack of eye contact and social isolation. As stated by the author (Ramachandran and Oberman, 2006) Patricia M. Rodier believes that “susceptibility to autism is inherited” and her theory is based on a “newly discovered class of nerve cells in the brain called Mirror Neurons” (Ramachandran and Oberman, 2006, p.64). These nerve cells take on the same characteristics of an Autistic...

...The quote, “The keenest sorrow is to recognize ourselves as the sole cause of all our adversities,” by Sophocles, exemplifies the idea of people realizing that they are the blame for all of their problems and difficulties. Essentially, Sophocles wanted people to realize that the saddest thing that you can experience or discover is that you are the cause of all of your own problems. As young children, people would blame others for simple things, such as someone else lying about doing one thing or another. However, at that age or point in our lives, we aren’t yet able to realize that this is a bad thing. As we grow up, we realize and discover that what Sophocles said is true; the only person we can blame for our problems is ourselves. For example,...

...This problem occurs because the eye cannot refract well enough to form an image on the retina. It usually occurs because the distance between the lens and the retina is too small or because the cornea-lens combination of the eye is too weak, resulting light from nearby objects to be focused behind the retina. Thus, a converging (concave) lens/contact lens/positive meniscus with the middle part of the lens thicker than the edges help refract light rays to converge and converge again at the cornea-lens combination to help focus light on the retina to see a focused, sharp...

...velocity of an orbiting body were increased, its orbital path would change to a parabola or hyperbola and it would escape the gravitational pull of the sun. It would then leave the solar system. Parabolas are the orbital paths of objects in the form of an open curve. If one cuts out an angle in a circular cone, it would follow this path parallel to the sides of the cone. Hyperbolas occur when a plane cuts across two parallels half-cones. Kepler’s laws applies to any situation where two bodies in the universe orbit each other due to their mutual gravitational attraction, not just two planets. For example: Moon’s that orbit planets, such as the four Galilean Moons that orbit Jupiter. #2)(A) The reflecting telescope, which uses a mirror to attract light was perfected by Isaac Newton in 1668 although it was developed by John Gregory in 1663. The refracting telescope, which uses a lens to attract light was developed by a Dutch optician in 1608 named Hans Lippershey. Two...

...latest in computers, material science, electronic detectors, and digital control in a system that warps and bends a mirror in a telescope to counteract, in real time the atmospheric distortion. The advance promises to let ground based telescopes reach their fundamental limits of resolution and sensitivity, out performing space based telescopes and ushering in a new era in optical astronomy. Finally, with this technology, it will be possible to see gas-giant type planets in nearby solar systems in our Milky Way galaxy. Although about 100 such planets have been discovered in recent years, all were detected through indirect means, such as the gravitational effects on their parent stars, and none has actually been detected directly. WHAT IS ADAPTIVE OPTICS ? Adaptive optics refers to optical systems which adapt to compensate for optical effects introduced by the medium between the object and its image. In theory a telescope’s resolving power is directly proportional to the diameter of its primary light gathering lens or mirror. But in practice , images from large telescopes are blurred to a resolution no better than would be seen through a 20 cm aperture with no atmospheric blurring. At scientifically important infrared wavelengths, atmospheric turbulence degrades resolution by at least a factor of 10. Space telescopes avoid problems...

...2. CENTRAL TOWER RECEIVER Central tower receiver consisis of a central stationary receiver to which the solar radiation is reflected by heliostats at A heliostat is composed of a large array of mirrors fixed to a supporting frame. This frame - axed to track the sun, as desired. The heliostats are installed in the open space and together they act like a dilute paraboloid. They tux solar radiation on a central receiver, which is stationary. Concentration ratios as high as 3000 can achieved. The absorbed energy can he extracted from the receiver and delivered at a temperature and pressure suitable for driving turbines for power generation. Figure 2.10 Central tower receiver The advantage of this system is that it eliminates the need for carrying the working fluid over large distance. As a result, the heat losses are reduced significantly. There are, however, many other problems associated with this system. A majority of them are due to heliostats and receiver. A large number of heliostats are required. to focus solar radiation required a large free space. The heliostats may be provided with pro such that self shading is avoided; at the same time achieving reasonable concentration .the cost, the cleaning of mirrors to remove dust and dirt poses another problem. The arrangement must be strong enough to withstand extreme weather conditions. The receiver must be able to effectively intercept the focused radiation, absorb it as heat and transfer...

...INTRODUCTION A mirror is an object that reflects light or sound in a way that preserves much of its original quality prior to its contact with the mirror. Some mirrors also filter out some wavelengths, while preserving other wavelengths in the reflection. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light. The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirrors are also used, to produce magnified or diminished images or focus light or simply distort the reflected image (“Mungan,” 1999). Geometrical optics, or ray optics, describes light propagation in terms of "rays". The "ray" in geometric optics is an abstraction, or "instrument", which can be used to approximately model how light will propagate. Geometrical optics provides rules, which may depend on the color (wavelength) of the ray, for propagating these rays through an optical system. This is a significant simplification of optics that fails to account for optical effects such as diffraction and interference. It is an excellent approximation, however, when the wavelength is very small compared with the size of structures with which the light interacts (“Hecht,” 1987). Glossy surfaces such as mirrors reflect light in a simple, predictable way. This allows for production of reflected images that can be associated with an actual (real) or extrapolated (virtual)...

...approach, Nayar writes, “The conventional wisdom, of course, says that companies must always put the customer first. In any services business, however, the true value is created in the interface between the employee and the customer. So, by putting employees first, you can bring about fundamental change in the way a company creates and delivers unique value for its customers and differentiates itself from its competitors.” The EFCS approach has four parts: * Mirror Mirror: Creating the Need for Change * Trust Through Transparency: Creating a Culture of Change * Inverting the Organizational Pyramid: Building a Structure for Change * Recasting the Role of the CEO: Transferring the Responsibility for Change Over the next two weekends, we’ll present excerpts from each of the four steps.] Employees First, Customers Second – Mirror Mirror: Creating the Need for Change The process we followed to get employees to see our situation at point A is one that eventually came to be called Mirror Mirror.

... (Math Teacher) Mrs. Sharon de Belen (Physics Teacher) Some of the pictures of Group 1 “Mathematics is the language of Science" This is a concept that links back to Galileo and is the reason why technology works, because the physical world obeys regular mathematical rules independent of any human belief system. Scientific concepts are interconnected by the rules of mathematics. Much has been written about why nature seems to work so well with these techniques. Sometimes, these Scientific and Mathematical concepts are hard to understand. We are afraid about solving those problems on Math and Science… but who would have thought that those fears will be replaced with amusement amd amazement.. Just like our minds telling us that “Math and Science are FUN!” Last November 14 and 15, 2012, the World of Science and Math came like a Big Bang! We thought Math...

...Mirror Mirror on the Wall"...we are more than conquerors through him who loved us." (Romans 8:37) We just can't help it everyday at some point we look in the mirror. To some it is an exercise in self-esteem: we see ourselves and say, "wow, I have a face that others could love!" But for most of us, it is more like an experience in reality: we see ourselves and think, "wow, I have a face that only a mother could love!" Either way, we all face questions like, "Why did God make me like this? Who am I? Does my life really matter? What do others think of the way I look and act? The problem is that we try and answer these questions from Hollywood's perspective- you know- Tinsel town? In Tinsel town everyone is beautiful and life is oh so much better than mine. Hollywood has created a monster called the "world mirror"... run for your lives! As a result, most teenagers suffer from what some call a poor self-image. They don't like the way they look. They think that they are being continually watched and criticized by others. After time and enough glances in the "world mirror" the poison of self-doubt, frustration, and discouragement creeps into their thinking. The real question, though, is not what we see when we look at our reflection in the "world mirror" Rather the true issue is what God sees when He looks at us - and that is a whole different story! The Bible tells us several truths about what He sees when He looks at us, because He is using the God Mirror so let's take a...

...used in media advertising, namely Photoshop. (Purtle, 2012) ("Mirror, mirror", n.d.) Studies have shown that American children receive an estimated 5,260 messages of attractiveness through the media, by adolescence. The United States also has the world’s highest rates of obesity and eating disorders. This statistic crosses a melting pot of backgrounds and cultures which eliminates any genetic reason; instead societal messages from the media should be addressed. (Ross, n.d.) Advertising Photoshopped Women Social problem Eating disorders in the United States has been a social problem for many years, with up to 24 million people of all ages and genders affected. 50 percent of these people also fit the criteria for depression and only 35 percent of these receive treatment. Considered a norm violation type of social problem, many eating disorders are directly and indirectly caused by the media advertising digitally altered body images in their campaigns. ("Eating disorders statistics", n.d.) Thus, the problem can now be considered a system-blame problem, which, blaming the system is only part of the truth behind eating disorders, and proves to absolve the person of responsibility for the disorder. (Long, 2012) Manipulation of images used in advertising through the use of Photoshop or some other digital tool can contribute to unrealistic body image expectations, eating disorders, and other emotional problems.

...Mirror Realism Matt Leonard Let’s suppose that spacetime substantivalism is true. In other words, space- time regions exist independently of the objects that occupy them. They shouldn’t be thought of as mere ‘things’ or ‘events’ which happen to stand in spatiotemporal relations.1 Even with such an assumption, there is a lot to disagree about. And so, for the moment, let’s make a few more assumptions: let’s suppose that (1) material objects exist independently of spacetime re- gions (i.e., material objects are not identical to spacetime regions) and (2) material objects are exactly located at certain spacetime regions. Given this setup, it seems right to say that material objects and spacetime regions pos- sess mereological and topological properties, and enter into mereological and topological relations. Now consider the following question about the relation- ship between spacetime and material objects: are material objects a perfect mirror of their spacetime regions? We might ask: if two objects share some mereotopological relation (for instance, if one is a part of the other, or if one is connected to the other), does it follow that the regions of space at which the objects are located, share the same relation? Similarly, if two regions of space are related in some mereotopological way, are the objects located at those regions, related in the same way? If an object x is a proper part of some other object y, does it follow that the location, lx, of the former object is a proper...

...point. Humans perceive beauty through themselves. With the complexity that is humanity, interpretations lead to beauty that a mere handful could witness. In modern society, perceptions are frequently biased. Sylvia Plath’s “Mirror” forces an objective outlook upon the reader to hint at an inward struggle with beauty. Likewise, Marge Piercy’s “Barbie Doll” depicts the life of a woman who sold her life in the pursuit of elegance. Most women are brought up to unrealistic standards that “guarantee” beauty if one plays along. Like a carnival game without winners, pursuing positive self-image could become an endless battle to some. Society, through various forms of media, discombobulates a desired appearance to heighten self-pity in women. To countless minds, beauty is everything. Using self-hatred wastelands also known as social media platforms, society influences entire populations. The poems “Mirror” and “Barbie Doll” enlighten this problem, however in times even before the digital age. To start, “Mirror” portrays a woman's loss of innocence through self-pity. As the woman in the poem looks for acceptable features in...
