THE HERO
Hero
When I think of a hero I immediately think of someone who is strong, intelligent, handsome, and daring. Upon closer examination, many different qualities than these become apparent. Courage, honesty, bravery, selflessness, and the will to try are just a few of the overlooked qualities of a hero. The definition of heroism changes with the context and time. Heroes of the past are not necessarily heroes of present time and vise versa. A person can be a hero for saving the life of one or of millions. Heroes are not only real people, but they are also fantasy figures. Children are extremely interested with legendary and fantasy figures because they take on such tasks as: difficult journeys, challenges with dragons, discovering lost treasure, and changing the nature of the world through their singular acts of courage and selflessness. They also endure much resistance, hardship, and danger. Often the hero learns valuable lessons about survival and self-reliance. Not only do heroes teach valuable lessons they give a child a sense of belonging. To a child, a hero is an invincible person who will change the world.
There is another type of hero that almost no one is
aware of. In the poorest areas of the country, live mostly minorities and other ethic background. All their lives they’ve been expected to work harder and expected not succeed in life. Some individuals living in poverty with a determination to succeed work hard all of their lives to become what everybody doubted they could. Escaping the crime, drugs, and prostitution is enough to escape hell, even if they don’t go to college. Despite of their financial problems, drug and crime surroundings, or difficulties in the language skills, their desire to triumph fuels their persistence. Those who make it to success are the few living examples of the purest form of hero anyone can be. They are not only their own heroes but also the heroes of the poor children who dream of becoming like them someday.
You also don’t have to kill anyone, conquer foreign land, or risk your life to be a hero. Anyone who influences anyone else by saving or helping save his or her lives is a hero. Dr. Martin Luther King Jr. changed the lives of millions of people by bringing justice to minorities. Mahatma Gandhi, one of the greatest heroes, led a nonviolent revolution to free his country. Even a parent can be a hero to his or her child by leading them in the right direction. All teachers are heroes when they make it their job to teach a child anything that will help them in life. You don’t have to go to great lengths by risking your life to make a difference in someone else’s life.
In conclusion, a hero is any person who changes the life of another person in a positive way. No one has to kill monsters, rescue girls, or lead a war to be hero. You don’t have to have superhuman strength or be known worldwide to be a hero. There is one characteristic that all heroes must possess. Whether you’re saving someone from a fire, leading a nonviolent revolution, or striving to succeed, you have to have courage to accomplish your goal. Everyone has a hero, but not everyone has it in him or her to be a hero.

Introduction & Summary
Computer system users, administrators, and designers usually have a goal of highest performance at lowest cost. Modeling and simulation of system design trade off is good preparation for design and engineering decisions in real world jobs.
In this Web site we study computer systems modeling and simulation. We need a proper knowledge of both the techniques of simulation modeling and the simulated systems themselves.
The scenario described above is but one situation where computer simulation can be effectively used. In addition to its use as a tool to better understand and optimize performance and/or reliability of systems, simulation is also extensively used to verify the correctness of designs. Most if not all digital integrated circuits manufactured today are first extensively simulated before they are manufactured to identify and correct design errors. Simulation early in the design cycle is important because the cost to repair mistakes increases dramatically the later in the product life cycle that the error is detected. Another important application of simulation is in developing "virtual environments" , e.g., for training. Analogous to the holodeck in the popular science-fiction television program Star Trek, simulations generate dynamic environments with which users can interact "as if they were really there." Such simulations are used extensively today to train military personnel for battlefield situations, at a fraction of the cost of running exercises involving real tanks, aircraft, etc.
Dynamic modeling in organizations is the collective ability to understand the implications of change over time. This skill lies at the heart of successful strategic decision process. The availability of effective visual modeling and simulation enables the analyst and the decision-maker to boost their dynamic decision by rehearsing strategy to avoid hidden pitfalls.
System Simulation is the mimicking of the operation of a real system, such as the day-to-day operation of a bank, or the value of a stock portfolio over a time period, or the running of an assembly line in a factory, or the staff assignment of a hospital or a security company, in a computer. Instead of building extensive mathematical models by experts, the readily available simulation software has made it possible to model and analyze the operation of a real system by non-experts, who are managers but not programmers.
A simulation is the execution of a model, represented by a computer program that gives information about the system being investigated. The simulation approach of analyzing a model is opposed to the analytical approach, where the method of analyzing the system is purely theoretical. As this approach is more reliable, the simulation approach gives more flexibility and convenience. The activities of the model consist of events, which are activated at certain points in time and in this way affect the overall state of the system. The points in time that an event is activated are randomized, so no input from outside the system is required. Events exist autonomously and they are discrete so between the execution of two events nothing happens. The SIMSCRIPT provides a process-based approach of writing a simulation program. With this approach, the components of the program consist of entities, which combine several related events into one process.
In the field of simulation, the concept of "principle of computational equivalence" has beneficial implications for the decision-maker. Simulated experimentation accelerates and replaces effectively the "wait and see" anxieties in discovering new insight and explanations of future behavior of the real system.
Consider the following scenario. You are the designer of a new switch for asynchronous transfer mode (ATM) networks, a new switching technology that has appeared on the marketplace in recent years. In order to help ensure the success of your product in this is a highly competitive field, it is important that you design the switch to yield the highest possible performance while maintaining a reasonable manufacturing cost. How much memory should be built into the switch? Should the memory be associated with incoming communication links to buffer messages as they arrive, or should it be associated with outgoing links to hold messages competing to use the same link? Moreover, what is the best organization of hardware components within the switch? These are but a few of the questions that you must answer in coming up with a design.
With the integration of artificial intelligence, agents and other modeling techniques, simulation has become an effective and appropriate decision support for the managers. By combining the emerging science of complexity with newly popularized simulation technology, the PricewaterhouseCoopers, Emergent Solutions Group builds a software that allows senior management to safely play out "what if" scenarios in artificial worlds. For example, in a consumer retail environment it can be used to find out how the roles of consumers and employees can be simulated to achieve peak performance.

Artifacts for Life
Acts of Love
When we allow ourselves to understand the impact our actions have not only on ourselves but the planet we live on, we realize the necessity to take loving action. We each have the power to correct conditions within as well as to affect the world we live in.
There are so many ways to apply love in our everyday lives. Yet, if we do not take care of ourselves, it is virtually impossible to feel and share love with the world around us. As an act of self-love, we can begin to educate ourselves and learn to take care of our physical bodies as well as keep our thoughts and feelings positive and loving. Nurturing ourselves also teaches us how to nurture life around us.
Practice constant acts of kindness and you bring kindness upon this planet. Forgiveness is the easiest and most powerful act of kindness you can make. Both for yourself and for others, this activity promotes unity, harmony and oneness that transmutes the old into the new.
This magnificent planet is filled with opportunities to experience love, tolerance, peace and joy. When we, as individuals, realize our potential to love unconditionally, we transform ourselves and the planet at the same time. Such is the power we wield every moment of every day. The choice is ours to create a world of joy and happiness, love and goodwill.
Every moment of every day is a new beginning. This can be a powerful mantra or affirmation. The meaning held in these words opens us to a new way of living and experiencing life. Each moment holds a new beginning of possibility and an opportunity to create without limitation. We can let go of what we perceive or believe is before us and allow our personal potential to shine through. Start each day as a new journey of self discovery. Let go of yesterday and tomorrow and embrace the power of now. Remind yourself daily of the newness of life in the moment.
Power of Peace
So many people are calling, praying and demanding peace upon our beloved planet right now. Let us all be reminded that true peace is found when we are at peace within. Be at peace and you create a world of peace. Do not just pray for peace, become peace itself.
Take the time to find the natural peace that resides within and you add to the real feeling of peace to everyone and everything around you. Let go of your fears and doubts and that of others. Be extremely discerning in what you focus your attention upon right now and question the messages and reflections. If it is loving, expand it. If it is less than loving, critical or in any way invokes hatred, fear or anger, release it and return to peace.
It is an amazing time and many would like to make you think that doom and despair, fear and attack, are waiting around every corner. Don't believe it. Create your own pictures of reality and fill them with peace and love. Walk in joy and harmony and know that all is well.
You can add your energy to this vision by contemplating peace and tapping into the higher desire for peace at any moment. This is especially helpful when you choose a particular time each day (for example 9 p.m.) to feel and think about peace for a few minutes, building a sustainable rhythm and habit.
A New Resolve
Who will you be in the future? How do you want to experience life? Will you be more kind, gentle, forgiving, tolerant and loving? Or will you continue to give your power away to the fear and doubt that is so prevalent right now in our society? The choice is ultimately yours.
Might we suggest a resolution to love unconditionally? (No need to wait until New Year's when "every moment of every day is a new beginning" - H. Becker) Within you is an unlimited supply of love and you hold the key to its release. Fear and doubt, anger and hate, have no more control over our lives than we allow. Can it be that simple? It really is. Loving is a choice we can make every moment.
Begin with yourself. Realize that you are a powerful, spiritual and angelic being and can create with love. Take care of your thoughts and feelings and make sure they reflect the positive you. Also observe your actions and insure that they have a loving intent too.
Even when our emotions get the best of us and the stress and concerns of life become a bit overwhelming, just remember we have tools of forgiveness, meditation, visualization and letting go to assist us in overcoming the negative experiences we encounter each day. Some things just are not worth worrying about or holding on to.
When you are clear and receptive to your own higher, loving nature, you can then direct this love to people and places around you. Your peace becomes the peace for others. Your love becomes the love other people feel.
Be the angel you are and choose to live freely and joyfully. In doing so, you make this a better world to live and love in!
Living with Love
The power of love is held within each of us every moment. This wondrous energy is available merely by our use and conscious recognition. When we choose to love one another we transcend the lower personality perceptions and rise to a higher truth. We recognize our oneness, wholeness and interconnectedness.
This is not a conditional love or the type of love one may try to use to earn favors or expect validation, rather this is a universal and unconditional love that recognizes the beauty in life every moment. It is of a higher nature. It is a natural expression that does not expect an outcome. It is giving just for the sake of giving.
It is in the sharing and giving of love to others that we receive the same that we give. Give love and surely you will experience love itself. Express love to the world around you and the world will reflect back to you the power of love.
Each of us desires to understand and realize this experience of love. Just listen to the lyrics of music and you will quickly see how much the notion of love plays a part in our personal journey of life. We seek it in our families, relationships, careers, religions, hobbies, and even at times we look to nature itself. All the while, it is right within us ready to be given out and experienced.
Love is such a powerful force especially when shared.
