New Crossover Operator Based On The Machine And Mutation...

Abstract - To solve the job shop scheduling problem more effectively, some genetic operators were designed. In order to increase the diversity of the population, a mixed selection operator based on the fitness value and the concentration value was given. To make full use of the characteristics of the problem itself, new crossover operator based on the machine and mutation operator based on the critical path were specifically designed. To find the critical path, a new algorithm to find the critical path from schedule was presented. Furthermore, a local search operator was designed, which can improve the local search ability of GA greatly. Based on all these, a hybrid genetic algorithm was proposed and its convergence was proved. The computer simulations were made on a set of benchmark problems and the results demonstrated the effectiveness of the proposed algorithm. Keywords –Hybrid genetic algorithm, Job shop scheduling, hybrid scheduler. 1. INTRODUCTION Job – shop is a system that process n number of tasks on m number of machines. In this type of environment, products are made to order and in a low volume. Usually, these orders are differ in term of processing requirements, materials needed, processing time, processing sequence and setup times.

Prostate Cancer And Its Effects On African Americans

Prostate Cancer in Brooklyn Chandra Tameshwar Nursing 304 Professor Dr. McDuffie Prostate cancer originates in the male prostate gland. Cancers in this gland are the most common malignancies, which grow very slowly, and can have minimal effect on a man’s quality of life. However, a tumor in the prostate gland can be problematic for men, especially black men, even though it is only about the size of a walnut. Located below the bladder and in front of the rectum, the prostate provides the fluid that nourishes and protects sperm cells in the semen. Researchers are still debating the cause of this disease, although certain risk factors such as age, ethnicity, culture, environment, diet, and family history, increase the chance of getting it. Prostate cancer affects African American men and early screening and detection are the key factors that can be used to prevent mortality and reduce morbidity, especially in the Brooklyn area. Prostate cancer is the second leading cause of cancer death in African American men and has the highest reported mor ¬tality rate, which is 2.4 times higher than in Caucasian men or any racial or ethnic group in the United States, according to The Centers for Disease Control and Prevention (CDC; 2014). African American males, including those from Jamaica, a Caribbean Island, have the highest prostate cancer incidence rates worldwide.

Theology Analysis Essay Example For Students

Theology Analysis Essay Many children are brought up as Catholics and remain Catholics, while many children grow up to hate the religion. Should parents press their children to be Catholic? Cant their children lead good and fulfilling lives without the theological baggage attained when one chooses to become religious? What is the difference that an ecclesial faith in Jesus Christ makes for a human being and for the world? Having faith in God gives people unchanging morals, guidance and something to believe in besides chance. Morals are different in every society and change over time as peoples values and views change. Though atheists can have good morals, their principles may change over time. Instead of following what is going on in our society, having faith in God and his ways gives unchanging morals that are always appropriate and peace everlasting. It gives Catholics security knowing that what they are doing is right. ?Jesus used these invitational and provocative forms of speech ? aphorisms and parables ? to subvert conventional ways of seeing and living, and to invite his hearers to alternate way of life.?(Borg, p. 75) How people view life and what they believe in determine how they will live their life. Having set morals instilled in them through Catholicism, children may be more inclined to be good. Being raised a certain way does not guarantee that a person will follow what they were brought up to believe. Raising a child as Catholic though makes a person more prone to leading a virtuous life. A lso, morals give Catholic families an anchor. When everyone believes in the same morals it creates unity and keeps peace. Following Gods ways according to Borg is ?The narrow way, the way less traveled, is the alternative wisdom of Jesus.? The way less traveled is life in the spirit and the life that Jesus himself knew. ?Our cultures secular wisdom does not affirm the reality of the Spirit; the only reality about which it is certain is the visible world of our ordinary experience.?(Borg, p. 87) Atheists look to the material world for purpose and contentment. They measure their self-worth according to how well they attained these values based on materialism, and if succeed they may find the rewards not fulfilling. Living the way less traveled is living a life centered in Christ in hope of fulfillment through Christ that is not based on materialism. Catholics feel they always have someone (God), someone that will never betray them and that will in the end make them content. Having faith in God gives us guidance. As we make decisions everyday, we sometimes get confused on what we should do. At these times, we can turn to God and think what would Jesus do? While some decisions may be as small as whether or not to keep the money when a cashier gives you too much change back, other decisions may be life changing. ?In the message and activity of Jesus, we see an alternative social vision: a community shaped not by the ethos and politics of purity, but by the ethos and politics of compassion.? Jesus believed in compassion. He did not feel that it was right to have a purity system that either made you really good or really bad. The purity system said that if you were a gentile, not whole (leprosy, damaged testicles or missing penis), female, poor etc., you were impure. Jesus did not feel this was fair. He went against this and helped those considered impure and even dined with them. Having a stance on compassion led to a society where everyone is included. Tho ugh most of society believed in the purity system, Jesus made the decision to go against what he believed was wrong. Just because something is tradition does not make it right. Catholics are able to look at the actions of Jesus and apply how he made his choices to their own life knowing that their decision will be morally correct. .u3e199da429a3258def421dda8661a07c , .u3e199da429a3258def421dda8661a07c .postImageUrl , .u3e199da429a3258def421dda8661a07c .centered-text-area { min-height: 80px; position: relative; } .u3e199da429a3258def421dda8661a07c , .u3e199da429a3258def421dda8661a07c:hover , .u3e199da429a3258def421dda8661a07c:visited , .u3e199da429a3258def421dda8661a07c:active { border:0!important; } .u3e199da429a3258def421dda8661a07c .clearfix:after { content: ""; display: table; clear: both; } .u3e199da429a3258def421dda8661a07c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u3e199da429a3258def421dda8661a07c:active , .u3e199da429a3258def421dda8661a07c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u3e199da429a3258def421dda8661a07c .centered-text-area { width: 100%; position: relative ; } .u3e199da429a3258def421dda8661a07c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u3e199da429a3258def421dda8661a07c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u3e199da429a3258def421dda8661a07c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u3e199da429a3258def421dda8661a07c:hover .ctaButton { background-color: #34495E!important; } .u3e199da429a3258def421dda8661a07c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u3e199da429a3258def421dda8661a07c .u3e199da429a3258def421dda8661a07c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u3e199da429a3258def421dda8661a07c:after { content: ""; display: block; clear: both; } READ: The Bald Prima Donna EssayWhile atheists just hope that things will turn out well, Catholics believe that their will is in Gods hands. Because Catholics believe this, they receive a sense of peace knowing that whatever happens, good or bad, it is in Gods hands and is for their betterment. ?My God, my God, why have you forsaken me? and then add, ?Into your hands I commend my spirit, into your hands, O absolutely incomprehensible God! That too is possible. In other words I can confidently meet death and also accept the fear of death in a final confidence and surrender.? (Rahner, p. 193) Though Jesus asked why God betrayed him, he trusted God. As, Jesus had confidence in God when he was crucified, Catholics always trust in God and his will for them. There is no need to question what occurs in peoples lives because whatever happens is Gods plan. Catholics do not fear or worry about things that much because they know that their life is in Gods hands. Having faith does not mean that Catholics do not feel fear or pain. ?I am not of the opinion that a Christian must necessarily die as a Stoic or as a Socrates. If a Christian can do so, there is no objection against it. But he or she need not.?(Rahner, p. 193) Knowing that their life is in Gods hands and that any obstacles they may encounter are for their improvement gives people confidence. Having faith gives people something to believe in besides chance. Whether or not one raises their children as Catholic Christians makes a difference. It is true that atheists can live decent and fulfilling lives without faith, but when things go wrong or they have a decision to make, what do they do? Who can they turn to? Having faith gives Catholics unchanging morals, guidance and something to believe in besides chance. In addition being Catholic guarantees salvation. An atheist may say that it does not matter if they believe or not because they do not believe in an afterlife. If there is an after life though, atheists will suffer. By being Catholic, one is ensuring that their future, if there is an afterlife, will be eternally secured. BibliographyThe Bible.Old edition

Plato the Original Feminist or the Original Reali Essays

Plato: the Original Feminist or the Original Realist Plato is one of the first and one of the only theorists to suggest the idea that women should be educated together with men and should be allowed to hold any position in the state, including serving in the military or as rulers. For his time, more than 2000 years ago, that was a radical idea. When questioned on the practicality of this idea he stated that "if the question is how to render a woman fit for the office of guardian, we shall not have one education for men, and another for women, especially as the nature affected is the same in both cases" (Plato 88). While Plato starts off on the right foot, it often feels as though he continually makes exclusions to this theory. Was Plato really an early feminist, or was he just trying to be practical? Did he want women to have an equal share in his utopia or was he just trying to get everyone on board? While Plato does believe women have the knowledge to be equal with men, they will constantly fall below them because they lack capa bility. In our modern day debate over gender equality, the issue of biological differences always comes up. The argument is given that because women are inherently different in their makeup that they are limited or incapable of doing certain tasks. But to quote from another theorist: "Men have been submitted to superior strength to enjoy with impunity the pleasure of the moment-- women have only done the same, and therefore till it is proved that the courtier, who servilely resigns the birthright of a man, is not a moral agent, it cannot be demonstrated that woman is essentially inferior to man because she has always been subjugated" (Wollstonecraft 107). Back then and still today, people believe that the inherent differences between genders should be the reasoning behind our labeled social standings. Plato does defend women in that he noted that physical differences are not universal; for example, although it may be true that most men are taller than most women, there are certainly some women who are taller than many men. What is more, he denied that there is any systematic difference between men and women with respect to the abilities relevant to guardianshipthe capacity to understand reality and make reasonable judgments about it. But while Plato is championing women's equality in some aspects, we can not conclude that he is a feminist for he still disparages women by stressing their inadequacies. He believes that women are more likely to fall to their desires and therefore are weaker in spirit. It is very hard to make progress when you are degrading the exact thing that you are trying to raise up. Plato was a man of realism and practicality. All of his choices and ideas for his utopian society revolved around what would benefit the most people and create the most good. He did not think about happiness on an individual level, but rather in a group mentality. And with that mentality, he realized that it would be most advantageous for him if he were to not is olate half the population. He probably assumed that there would be some women that would be helpful to society, so he figured it wouldn't hurt to give them the opportunities to prove themselves. Plato believed that women were likely to be emotional and listen to their desires thereby making them unreliable beyond the role of guardian. "...they will receive lighter duties than the men, because of the weakness of their sex." While Plato saw the potential for women to be equals with men, he just didn't see them ever being as able as men. But modern day scientists don't agree. In a study done by Harvard Men's Health Watch, studies showed that: "In medical terms, men are the weaker sex, Why? It depends on a complex mix of biological, social, and behavioral factors. Biological factors include the fact that, compared with men, women have substantially higher levels of HDL (good) cholesterol, which protects against heart disease. In addition, excess weight although common in both sexesis mo re of a problem for males.
