Bernido and l\faria Victoria Carpio-.Rernido Research Center for Theoretical Physics Central Visayan Institute Foundation Jagna, Bohol 6308, Philippines The Ascending Levels of Learning and Pedagogical ~1axims that could guide effective teaching of physics are presented. As an example of how these may be applied, the Dynamic Learning Prof:,lfam (DLP) of the Central Visayan Institute Foundation is briefly discussed. The DLP, together with 21st century technology, provides a scenario where the perennial lack of high school physics teachers in the Philippines can be bypassed. Introduction The breadth of topics that may be covered in teaching physics can be extremely wide. After all, physics probes the smallest things in the universe (the quarks and leptons), aiJ the way up to the "biggest" subject one can think of-the birth, death, and fate of the universe itself. One definition for physics states that it is the study of matter and energy. Most everything in the universe is either matter or energy, and this can make physics quite interdisciplinary. No wonder, therefore, that sub-areas in physics may be referred to as Biophysics, Geophysics~ Chemical Physics, Mathematical Physics, Astrophysics, Nuclear Physics, Econophysics, etc., and one also has the physics of sports, the physics of art, and so on. Because of its breadth, there is always...

...a woman and a Jew, she was paid a minimal amount of money and was not given the status of a professor. In 1929, Emmy Noether was welcomed to the University of Moscow as a guest lecturer. She was a member of the Göttingen University mathematics department until 1933. This was when the Nazis took over and she was unable to continue teaching in Germany. In 1933, Noether moved to the United States and continued her teachings at Bryn Mawr College in Pennsylvania as a guest professor. Here, she was paid a full salary and accepted as a proper part of the staff. In the U.S., she also taught at the Institute of Advanced Study at Princeton. Noether published many papers while working at the University of Erlangen. She also began her research on theoretical algebra and teamed with Felix Klein and David Hilbert working on Einstein’s theory of relativity. In 1907-1919, Noether concentrated on the field of algebraic invariant theory, the Galois Theory, and Physics. She proved two theorems of particle physics and general relativity. ‘Noether’s Theorem’ is one of the most significant contributions to the development of modern physics. In 1920-1926, she devoted her time to the theory of mathematical rings. She developed an abstract and conceptual way to approach algebra. This resulted in principles that unify topology, logic, geometry, algebra, and liner algebra. Noether’s works were a breakthrough in abstract algebra. Her studies on chain conditions and ideals of commutative rings were honored...

...EXPERIMENT 3 GROUP B AIM: To find the overall efficiency of plate column operating under total reflux, for a binary system (iso-propanol & n- propanol). APPARATUS: * Distillation Column with reboiler * Automatic digital refractometer * Two fluids with different volatilities. PROCEDURE: * Distillation column was filled with the two fluids. * Then we switched on the heater and set the temperature to 126.6 ̊C * And then we allow the system to reach the equilibrium. * The equilibrium was tested by taking out the samples (from reboiler & distillate) at the interval of 10min such that the refractive index hence concentration was made constant. THEORY: Distillation is one of the most common separation techniques used in the chemical and petroleum industries. It is defined as “a process in which a liquid or vapour mixture of two or more substances is separated into its component fractions of desired purity, by the application and removal of heat. Distillation provides the basis for separating numerous substances into valuable components. The components of a mixture are separated based on relative volatilities, which depend on the differences in boiling temperatures of the components making up the mixture. The separation becomes easier as the difference between the relative volatilities increases. The component with the lowest boiling point flows to the top of the column as a vapour, condensed and exits the column as the distillate. A percentage...

...is when Planck first got an interest in physics and learned the principle of conservation of energy. He began the studies in 1874 at the University of Munich and studied theoretical physics. After he graduated, he taught math and physics briefly. Planck completed his habilitation thesis and began lecturing in Munich without getting paid becuase he was waiting to be offered a new postion. He also furthered his work on the field of heat theory. Planck then became a professor at Berlin University and joined the Physical Society. As far as Plancks home life goes, he married and had four children. He was friends with theologian Adolf con Harnack and his home soon because a social center. Famous scientists like Albert Einstein and Otto Hahn all frequently visited. His wife died and he remaired and had his third son. Planck's two sons and two daughters all died. By the end of the 1920s, Bohr, Heisenberg, and Pauli had worked out the interpretation of quantum mechanics, but Planck rejected it. He expected that wave mechanics would render the quantum theory, even though this can not be the case. Further work only cemented quantum theory, even against Einstein's revulsions. He originated quantum theory, which won him the Nobel Prize in Physics in 1918. Max Planck made many contributions to theoretical physics, and is very famous for being the originator of quantum theory. He ended his life at Göttingen on October 4, 1947, but he has contributed so much for the...

Nonlinear Modelling Application in Distillation Column Zalizawati Abdullah, Norashid Aziz, and Zainal Ahmad Abstract Distillation columns are widely used in chemical processes and exhibit nonlinear dynamic behavior. In order to gain optimum performance of the distillation column, an effective control strategy is needed. In recent years, model based control strategies such as internal model control (IMC) and model predictive control (MPC) have been revealed as better control systems compared to the conventional method. But one of the major challenges in developing this effective control strategy is to construct a model which is utilized to describe the process under consideration. The purpose of this paper is to provide a review of the models that have been implemented in continuous distillation columns. These models are categorized under three major groups: fundamental...

...The insight that sparks innovation appears to occur randomly. After all, the iconic shorthand for innovation is a light bulb, implying that ideas come from sudden flashes of inspiration. While such flashes are surely good things, it is hard to depend on them, particularly if you are at a company that needs to introduce a steady stream of innovative ideas. Steve Jobs once said, “It is not the customer’s job to know what they want.” That’s absolutely right. It is yours. And don’t think you don’t have a customer because you work in an internal support function or for a company that provides components or services. Everyone has a customer, whether it is a purchaser, user, or co-worker. "More than 50 years ago Peter Drucker wrote, 'The customer rarely buys what the company thinks it sells him.'" The quest to identify opportunities for innovation starts with pinpointing problems customers can’t adequately solve today. More than 50 years ago Peter Drucker wrote, “The customer rarely buys what the company thinks it sells him. One reason for this is, of course, that nobody pays for a ‘product.’ What is paid for is satisfaction.” Companies think they are selling products and services, but in reality people hire those products and services to get jobs done in their lives. As marketing guru Ted Levitt quipped to his students a generation ago, “People don’t want quarter-inch drills--they want quarter-inch holes.” A problem arises, and the customer looks around and chooses the solution...

...Eddie Liu committed the theft to satisfy his selfish needs, but in the process, all parties concerned had to bear the consequences. First, Lee and Li’s reputation was seriously affected in Taiwan and abroad. The firm’s core principles of excellence in quality and client service were jeopardized since Liu used Sandisk’s shares to perpetuate the fraud. Prospective clients might find it difficult to trust the firm and would prefer taking their business elsewhere. Besides losing important clients, Lee and Li would have to make extra effort to restore its tarnished image. Second, apart from the fact that Lee and Li had no insurance to cover the embezzlement, partners in Taiwan shared unlimited liability. Therefore, lawyers like Paul Hsu, C.V Chen and Kwan-Tao Li were more vulnerable in this situation: they faced the possibility of loosing all of their possessions and professional livelihood. Third, Lee and Li could face bankruptcy and might be forced to close down. Consequently, lawyers and staff working at the firm would lose their jobs and would not be able to provide for their families until they found another job. After being informed about the embezzlement, Lee and Li should take corrective decisions and act quickly to ensure that the firm survives. Since news of the fraud hadn’t made the headlines yet, senior partners should first try to handle the situation internally. In this scenario, it is crucial that they are surrounded by highly-trusted people to help bring the...

...Theory of Computation [Name of the Writer] [Name of the Institute] Theory of Computation It is a set of rational, systematic, and functional knowledge, focusing on the study of the abstraction of the processes occurring in reality in order to play using formal systems, i.e. through character codes and Instructions logical, recognizable by humans, capable of being modelled on the limitations of devices that process information and perform calculations, such as the computer. For this it relies on the theory of automata to simulate and standardize these processes, as well as to formalize the problems and solve them (Manna, 2012). Automata Theory This theory provides mathematical models that formalize the concept of computer or simplified algorithm and broadly enough so that they can analyse their capabilities and limitations. Some of these models play a central role in several applications of computer science, including word processing, compilers, hardware design and artificial intelligence. There are many other types of robots such as random access machines, cellular automata, abacus machines and abstract state machines; but in all cases it has been shown that these models are not more general than the Turing machine, and then the Turing machine has the ability to simulate each of these automata. This leads to think that the Turing machine as the universal computer model (Manna, 2012). Computational Complexity Theory Even when a problem is computable, it may not be...

...APPLICATIONS OF AUTOMATA THEORY IN INFORMATION AGE 1. DEFINITION Automata theory is the study of abstract machines and automata as well as the computational problems that can be solved using them. It is a theory in theoretical computer science, under discrete mathematics (a section of Mathematics and also of Computer Science). Automaton comes from the Greek word αὐτόματα meaning "self-acting". So, Automata Theory is the study of self-operating virtual machines to help in logical understanding of input and output process, without or with intermediate stage(s) of computation (or any function / process). 2. APPLICATIONS 2.1 Vending Machines Figure 1 presents a DFA that describes the behavior of a vending machine which accepts dollars and quarters, and charges $1.25 per soda. Once the machine receives at least $1.25, corresponding to the blue-colored states in the diagram, it will allow the user to select a soda. Self-loops represent ignored input: the machine will not dispense a soda until at least $1.25 has been deposited, and it will not accept more money once it has already received greater than or equal to $1.25. To express the DFA as a 5-tuple, the components are defined as follows: 1. Q = {$0:00; $0:25; $0:50; $0:75; $1:00; $1:25; $1:50; $1:75; $2:00} are the states 2. ∑= {$0:25; $1:00; select} is the alphabet 3. ∂, the transition function, is described by the state diagram. 4. qₒ = $0:00 is the start state 5. F = ᵠ; is the set of accept states [pic] 2...

...leaders that are well-rounded and well-informed, leaders that are charismatic and driven, leaders that know for certain what they are doing. Mr. Lee Kun Hee, as the new leader of Samsung Electronics on 1987, after having replaced his late father in managing the corporation, was described as a person- and a leader- very much in tuned with himself. With his self-proclaimed fixation to race cars, fast-and-bordering-to-dangerous driving, movies, and canine friends, Mr. Lee can be described as a person very comfortable in his own skin. A graduate of top-calibre universities from Japan and the United States, Mr. Lee’s knowledge of business and management can be claimed as having been gotten from the world’s best sources. One would think that his unique personality—described by his preferences—along with his family and educational background would make him a leader so charismatic that immediate compliance from his people is a given. However, this can hardly be the description for Mr. Lee’s journey in making Samsung Electronics the ‘Technological Powerhouse’ that it is today; quite the opposite, in fact, if we would be forced to describe. Now one of the leading names when it comes to technological consumer goods, one would never imagine the challenges that this conglomerate has undergone in order to achieve its place today. Samsung, before Mr. Lee Kun Hee’s commencement of management way back in 1987, was described as a company...

...“How Does Harper Lee Present Her Ideas About Childhood in the Novel ‘To Kill A Mockingbird’?” In the novel ‘‘‘To Kill a Mockingbird’’’ written by Harper Lee, childhood is expressed throughout the story. The narrator of ‘‘‘To Kill a Mockingbird’’’ is Scout, an adult when the book was written, but a child when the story was lived, with this narration Harper Lee, uses Scout to portray the events which, normally would have had a biased review by adults at the time, but because it is written by a child it has non-judgemental views. Therefore, because of the child narrator, and the other main characters being children, this shows that childhood in ‘‘‘To Kill a Mockingbird’’’ is important and crucial. In the chapters 1 to 12, childhood is presented by friendship, gullibility, pride, questioning and fear. The fear element, is a major part through ‘‘To Kill a Mockingbird’’, because at different stages of the novel at least one of the main characters is scared. The Finch children first experience real friendship in ‘‘‘To Kill a Mockingbird’’’, when they meet Charles Baker Harris – Dill. Before Dill has passed the ‘Jem test’, Dill boasts to Scout and Jem that he can read. Which was not usually common in Maycomb at the time, but Jem and Scout could both read, which meant that they thought Dill was showing off and they wouldn’t want to be friends with him. Also what makes Dill become an issue about friendship, is how he introduces himself. He recites his entire name, and makes fun of...

...The impression shapes our nature Obviously, when it comes to the talking subject of superheroes, boys are always the more exciting ones in our childhood. They admire their power and are wild about acting as one of them when doing the games. In contrast, girls are typically ones who have paid more attention to fairy tale that express friendship, love or whatever sentimental feelings. And when I memorize to consider that if there is a superhero that affects my childhood, or what we say, the formative years, I cannot even remember a superhero’s name except Monkey King, who is the character in one of great Chinese masterpiece and is famous enough for every child in China to know. So the point here is clear. It is definitely not a big part of my childhood and I wasn’t affected by it that much, at least not more than the influence The Little Mermaid had on me. I conclude the reasons why most of girls, at least in my age, don’t have such deep connect with superheroes are various. One of the reasons is that heroes are always male. And since kids prefer to substitute themselves into the stories they read and imagine that they are the protagonists, the fact of less or no female superheroes in most of stories prevents that action and leads to less sense of emotion resonance. And in some degree, the fact of less or no female superheroes does give us the hint that male should be the ones who protect and female should be the ones being protected. So, does it shape my perception of gender...

...BUS 568 Marketing Communications April 6, 2014 I selected to write my article about Evian when I came across their advertisement in Adweek.com. The article caught my attention because it was featured as Adweek’s ad of the day titled “Evian Spins a Familiar Web with a Dancing Baby Spider-Man BETC gets heroic in the latest outing”. The title grabbed my attention and I was curious to read the article and of course watch the YouTube video. I have always been a fan of the Evian commercials and their use of Computer Generated Imagery (CGI) babies coming together in a group to swim, dance, roller skate, etc. and therefore I was curious to learn more. I’m sure most people have the same reaction as I do when I see a cute baby, but a cute one year old performing in the commercials is even better. I hadn’t seen The Amazing Spider Man 2 commercial but after viewing the YouTube video, I was even more in love with Evian’s marketing by using the CGI babies, however, I do agree with the author Emma Bazilian in that the Spider Man 2 commercial is very similar to Evian’s “Baby & Me” commercial just different characters. “Baby & Me” starts when pedestrians walk by a man dancing in front of a mirror to the song “Here Comes the Hotstepper” except his reflection is not of him as an adult but as a baby. All the other pedestrians that come to observe also see their reflection when they were a child and they all join in on the party. Since music is universal and it’s a great way...

...around seventy-five teenagers at the party, along with loud music and dancing. What I thought was going to be a great night, turned out to be the night my courage would be tested. As I was talking to some of my friends I noticed something was wrong with them. Shortly after, I noticed that their behavior was different, I realized that I was smelling the scent of marijuana. Before I knew it I was being offered some of their drugs. I thought about the consequences that were to come if I had said yes to their offer. I felt that if I had said yes, I would have let down so many people, but most importantly myself. Having courage gave me the will to say no to the drugs and walk away from the peer pressure. In the novel To Kill a Mockingbird by Harper Lee, both Atticus Finch and Mrs. Dubose exemplify moral courage. Throughout the novel Atticus was portrayed as a man of great courage and integrity. Atticus had to discuss concepts with his daughter Scout when they were at Finch Landing. Scout wanted to know why Atticus was going to defend Tom Robinson if he already knew he was going to be defeated. Atticus then explained to Scout that, " simply because [Atticus and Scout] were licked a hundred years before [Atticus and Scout] started is no reason for [Atticus and Scout] not to try to win" (76). Atticus was demonstrating his courage by proving that no matter how hard things get, you should never give up, and that you should always fight for what you believe in. Atticus...
