Different Types of Technology used in Criminal Justice Essay

Different Types of Technology used in Criminal Justice - Essay Example Drug testing technology has become a common factor in the American criminal society. Drug testing’s application is far-reaching in many fields such as police forces, airline pilots, federal employees and even participants in school sports. Also, prospective executives of the National Institute of Justice have to go through drug tests as regulations of employment. In the field of criminal justice, the moderately inexpensive and considerably powerful drug test to determine drug use has opened a broad range of issues that reach into unfamiliar territories of policy, law and practice. Criminal fighting agencies use this technology to fight drug abuse in America mostly the police force and anti drug agencies. Another influential technology is the DNA technology. DNA allows criminal fighting agencies to match a genetic sample to a person at a mathematical level that has total assurance. DNA tests are frequently used in roughly all jurisdictions across the country. DNA testing is use d in connecting a suspect to a crime (Lazer, 2004). A key agency that uses this technology in the U.S. is the Federal Bureau of Investigation (FBI). Concealed weapons detection technology is a technology that permits criminal fighting agencies to locate hidden weapons. Police officers, court security officers plus other enforcement officials can now predict whether or not a person is carrying a firearm (Gibbons, 1988). This helps to maintain law and order in the society since people carrying firearms could easily be tracked (Gibbons, 1988). Information technology helps criminal fighting agencies to locate information regarding crime or a location that is prone to criminal activities. Police officers can verify the history of a suspect through fingerprints, fill in paperwork in the squad car through using a hand-sized laptop, and go back to patrol. This technology is mostly used by the police force such as probation officers to track the activities of probationers

Social Identity Theory and its Impact on People’s Reactions to Petrol Queue Jumping Essay Example for Free

Social Identity Theory and its Impact on People’s Reactions to Petrol Queue Jumping Essay Abstract This study aimed to investigate whether the social identity theory applies when it comes to peoples’ reactions to petrol queue jumping. It intended to ascertain whether participants demonstrated more reaction to those who jump queues, outside their own in-group (those who drive luxurious cars as opposed to non-luxurious car drivers). This study was influenced by a similar experiment conducted by Helweg-Larsen LoMonaco (2008) about queuing among U2 fans and their reactions to queue jumping. The experiment involved 49 participants who indicated they didn’t drive a luxury car, in a Melbourne metropolitan petrol queue, 26 of whom were males, aged 18-58 years (M =33:82; SD = 11. 26), in addition to this there were 23 females, aged 18-61 years (M =33.11; SD = 11.26). A questionnaire was utilized which included basic information as well as strength of identification with other drivers. Assessment of how upset queue jumping made them feel on a scale of 1-7 was also utilised. The results demonstrated that there was a reasonably high reaction rate, with statistically significantly results that proved drivers have a high level of social identification amongst other drivers within the same social class. The hypothesis that those who operate a non-luxurious vehicle will appear more distressed about queue jumping, when it is by someone driving a car of luxury as opposed to someone who is driving a car that is considered non-luxurious was supported. This helps support the existence of the social identity theory although the implications of this are that perhaps a broader definition of what ‘reaction’ to queue jumping needs to be developed, as well as using a larger sample size of people from several states or perhaps even countries. Social Identity Theory and its Impact on People’s Reactions to Petrol Queue Jumping It’s normal for most people to have a fundamental curiosity for finding out the causes of and therefore finding explanations for the behaviours demonstrated by humans. It is via this inquisition that queue jumping is explored, it is recognised as a human behaviour that most people will have to deal with in their everyday lives. It is generally known as the social phenomena where another person skips the line and rather then waiting at the  end of a queue. Queue jumping, as it is commonly known, has been researched in various cases including research within the animal community. Particularly in a study about wasps, which demonstrated that queue jumping may be seen as a rule for inheriting dominance (Bridge Field, 2007). This is not the sole study in regards to queue jumping, Milgram et al (1986) investigated the responses to queue jumping by assigning intruders to wait in queues (either single or multiple confederates) and they found that if there were more than one intruder it would provoke more of a reaction amongst the participants. They were also able to deduce from this study that those who preceded the intruders in the line felt more distaste for the queue jumpers as opposed to those in front of the queue jumpers (Milgram et al, 1986). This study demonstrates the social implications that queue jumping can have on an individual and the reason that so much weight has been assigned to the importance of researching queue jumping is because through this human interest, social theories, such as the â€Å"Social Identity Theory† have taken place. Social Identity Theory is a theory based on group membership as well as intergroup interactions that are based on self-categorisation, social comparison and the structure of a shared self-definition in terms of ingroup-defining properties (Vaughan Hogg, 2011). There are two dynamics to social identity that are attributing causality for behaviours, these include: social identity, which is the definition of self in terms of group membership as well as personal identit y, which is when one defines self in terms of personal relationships and traits (Vaughan Hogg, 2011). The main component to the social identity theory is the in-group/out-group differentiation which â€Å"is an inevitable characteristic of social life, and many social psychologists are still very busy with the issue of intergroup differentiation† (TaÅŸdemir, 2011). This study is relatable to other research particularly one executed by Thoitis Virshup (1997) in which groups of people were classified into â€Å"me’s and â€Å"we’s† and this is a clear representation for in-groups and out-groups. They discussed the notion that there is a sense of obligation and protection of one’s own ingroup as they are willing to empathise with those perceived to be similar to the individual as oppose to the â€Å"we’s† who were seen as dissimilar to the individual (Thoitis Virshup, 1997). In terms of human behaviour, social identity theory and queue jumping can be  closely interrelated as queue jumping has been was investigated by Helweg-Larsen LoMonaco (2008). In this study U2 fans where given a questionnaire whilst waiting in an overnight line to obtain floor spots at his concert the following day. The purpose was to reflect on their reactions to line-intrusion and the results showed that the queue is a social system and line intrusion was most upsetting to fans with a greater the commitment; the more dedicated the fan the more upset they were by queue jumping (Helweg-Larsen LoMonaco, 2008). In regards to queue jumping, there is much curiosity as to whether the social identity theory can be proven but little research. It is important to study reactions to queue jumping simply because of the social implications that are derived from this, as understanding how people function within a social in-group and how they react to an out-group can be vital. Through this knowledge one may able to apply this to discover solutions to problems such as peak hour traffic and how to best overcome this problem and avoid road rage and car-crashes. With that in mind the study below aims to investigate whether social identity affects how upset people feel about jumping a queue in order to purchase petrol. It is predicted in this study that those who operate a non-luxurious vehicle will appear more distressed about line intrusion, when it is by someone driving a luxury car rather that a non-luxury vehicle. This prediction is based on the social identity, assuming that the social identity theory can be demonstrated. Method Participants This study involved 49 participants who indicated they didn’t drive a luxury car, in a Melbourne metropolitan petrol queue, 26 of whom were males, aged 18-58 years (M =33:82; SD = 11.26), in addition to this there were 23 females, aged 18-61 years (M =33.11; SD = 11.26). Design The scheme utilised in this study was a one-way between-factor design. In relation to queue jumping it compared participants reactions from (LUXURY) whether the queue jumper drove a luxury car in which 24 where allocated and (NON-LUXURY) whether the queue jumper drove a non-luxury car in which 25  participants were allocated. As well as the main dependant variable being the measure of how distressed people felt about the queue jumping. Materials/Apparatus A questionnaire including background information (such as age; gender; number of years driving; type of car driven; how long they had been waiting in the petrol queue; whether they had waited in petrol queues before; whether they had ever witnessed queue jumping and when; and how much they usually paid for petrol) was employed. The questionnaire also evaluated their strength of recognition with drivers of non-luxury cars using Brown, Condor, Mathews, Wade and Williams’ (1986) 10-item measure of social identification (1 =strongly disagree; 7 =strongly agree). A total maximum score of 70 was possible on this measure. The questionnaire also implemented four items that each measured how distressed queue jumping (overall) made them feel (1=not at all upset, to 7=extremely upset). These items were revised versions of questions included in Helweg-Larsen and Lomonaco (2008) and a single measure/index (called REACTION) was calculated by summing the answers to these four items; with hig her figures indicating that people were more distressed by the queue jumping. A total maximum score of 28 was possible on this form of measurement. Procedure Ethics approval was first obtained from Deakin University Human Research Ethics Committee. Participants were then selected in the Melbourne metropolitan region petrol station where queuing for reduction of petrol prices happened frequently. In the first occurrence, four drivers were employed and were requested by the experimenter to act as experimental stooges. Two of these drivers were required to drive a luxury car: 1. a Maserati GranCabrio Sport; and 2. a 2012 model Porsche 911. One of these (luxury car) drivers was asked to take up a place in a petrol queue and allow queue jumping to happen, while the remaining driver was expected to jump the queue to the place immediately preceding to that drivers location in the queue. The other two drivers were asked to drive a non-luxury car: a Ford Fiesta or a Holden Astra. One of these (non-luxury car) drivers was also required to take up a place in the petrol queue and to allow queue  jumping to happen, while the other driver was asked to hop the queue in the place immediately preceding that drivers place in the queue. This meant that other people in the queue were open to the elements of queue jumping, that was being put up with, either among luxury car drivers or among non-luxury car drivers. The two queue jumping incidents were staged to take place at a distance of 10 cars from the petrol pumps, within the same day but separated by two hours in time (with queues stretching for numerous blocks). No other queue jumping, besides those associated with the current study, was observed to have taken place. Each of the participants in the queue behind the place where the queue jumping occurred was approached, after the incident, by one of four experimental research assistants and they were then asked to answer a questionnaire about queuing for petrol. At the conclusion of the study, all participants were debriefed and notified that they were permitted to contact the experimenter to gain access to results. Results Table 1 Mean and Standard Reaction to Queue Jumping of Luxury and Non-Luxury cars N Mean Standard Deviation LUXURY 2425.712.10 NON-LUXURY 25 23.60 2.14 TOTAL 49 24.63 2.35 The results from Table 1 illustrate that the total Mean was 24.63, where the maximum response possible was 28 for REACTION (as well as a maximum of 70 on the social identity scale) and the total Standard Deviation being 2.35. This indicates that the scores were relatively high in regards to the total amount possible. Using SPPS version20, a one-way between variable factor, ANOVA was carried out on the dependant variable of REACTION. Reaction was perceived bigger when the queue jumping was done by a luxury car driver (M=25.70; SD=2.09) as opposed to when it was by a non-luxury car driver (M=23.60; SD=2.14);(F(1, 48)=12.12;p

Horror Films Special Effects and Cinematography

Horror Films Special Effects and Cinematography From our child hood we have been imagining ghosts and seeing imaginary things that are almost improbable to exist to give us terrific fears and these fears come to haunt our dreams. Watching a horror movie gives us that old feeling of fear and makes us emotionally attached to the film. The horrific images from the movie with its special effects and sudden sounds would make many watch them even though its scary. But almost all the horror movies end after balance is restored and everything turns to normal to give the audience a sense of satisfaction. The dissertation is based on the Study of cinematography and special effects in a Horror movie. In the recent past camera, lighting and special effects are of greater importance and fame, so it will be worth exploring those topics. As far as the technical aspect is concerned a brief research of how these kind of films are being filmed from the shooting spot itself, will be very useful for an aspiring artist to get a better idea about its development. Horror films go back as far as the onset of films themselves, over 100 years ago. Introduction: The researcher was interested in watching horror films from his childhood and he was deeply interested in these genres. In his childhood the researcher was very much impressed with the serial mainly called Genmam-X and Marmadesam. The drama that he staged in his schooldays with horror and scary effects as the theme was applauded well by the audience. The tremendous response from the viewers made him start learning the concepts and idea relating to this genre and finally concluded with this concept. It is difficult to show scary effects in screens. If the director gets his requirements from all the technicians the film will be successful, otherwise it will not. In order to get success the film must contain interesting characters and it also depends on their acting. And in terms of technical aspects the cinematography and special effects play a major role. In Indian cinemas, there is some response for these kinds of genre when compared to Hollywood. The main aim of the upcoming short film is that after seeing this, many people have to change their mind to see horror films also. So the main thing that the film should contain is better cinematography with matching special effects. Instead of concentrating on the story alone, cinematography and special effects should be given more importance. Aim: To give the thrill the viewer expects mainly the use of the camera, lightings and Special Effects, Were Script play the secondary role. Statement of the problem: The main purpose of adding the special effects is to frighten the viewer. When it goes beyond the limit it might not be watched by many people. In this situation it may go to another genre of hardcore horror. It may scare people but it will create some abnormal effects in the minds of some people. Objectives: How is cinematography in horror films different from other films? What are special Effects? How is Special Effects done in horror movies? A Study of the cinematography for horror movies. How is make up done for horror movies? Research Questions: What are Special Effects? Colors and intensity of lights? Camera trick and technique in cinematography? Special Effects (Make up) for horror movies? How the horror movies getting winning changes? Significance of the study: Horror movies are the best platform to find rich special effects and lighting and Much interesting camera handling which gives the viewers a different experience From other films. The study through this dissertation is to understand The cinematography in horror films and application of special effects in them.

The cinematography is done by John L.Russell. Psycho is one of the best Hollywood horror movies best for lighting. In one scene the psycho is going to kill the lady who is taking her bath were the lighting was done very well to signify the horror. It is considered to be the best cinematography, in 1961 by John L.Russell .Oscar was nominated for this film. Reference: The Thing (1982) directed by John Carpenter with Special Effects by Rob Bottin. The movie was taken in 1982. In that period they used special effects and visual Effects and make up. The makeup was so realistic that it attracted the viewer Quickly. A human is transformed to a demon easily and the scene is presented very effectively which will fascinate the people. . The comment was that it was too scary. This shows how they have applied VFX and SFX. And the Best special effect 1982 Rob Bottin Saturn award was nominated for this Film. Reference: Van Helsing and the director is Stephen Sommers.The cinematography is handled by Allen Daviau. The movie Van Helsing comes under the genre of horror and it came out in the year 2004. In this movie they followed a really nice cinematography. Actually this movie came out from the comic that Van Helsing is a ghost hunter who will be roaming around the earth in search of ghost, In this movie also he is coming to a village in search of the ghost. There are two interesting characters in this movie. One is the Frankenstein and the other one is the wolf character which was in the custody of the villain. The extra ordinary thing about the movie is that the CG In early days, man used special effects and later it got developed into visual effects. In this movie there are many visual effects shots. A few examples include the climate sequence where the ordinary man transforms into a wolf that is a quality CG work in the industry. Further there are many VFX shots in the movie. Special effects include the blood bossing from the mouth and the usage of the miniature in the movies where Gabrie l (hero) taking the Frankenstein away from the village. Most of the shots were shot inside the studio and they were composited later. Usage of expressive and breath taking matte paintings added to the quality of the movie. The cinematography of the movie plays a major role because of the proper establishment and composition. Reference: Mirror-2 directed by Victor Garcia. Cinematography is done by Lorenzo Senatore. It is really a kind of hardcore killing movie where we can find the hero who is replacing the old security guard in the office. The main concept behind this movie is the revenge by the girl who is killed by the head officer. And he is killing the people through the medium mirror. The main success behind the movie is the lighting and cinematography. Reference: Saw-4, directed by Darren Lynn Bousman and cinematography by David Armstrong. This movie is the successor of the three early parts. The success behind the movie is the usage of the equipments and the method he used for killing others. In the first scene of the movie the villain killed the victim by tying the body to a steel bed and the axe was in a to and fro motion just above the stomach of the victim where it got peeled into many pieces. Website Reference: This Media Studies Factsheet was researched Written by Steph Hendry The horror films are not from this period. Those films were taken from the very early times where they only depend on the special effects and the camera tricks .At that time also some nice pictures came namely the Frankenstein a ghost which was made by a man by assembling many internal organs .This is the fact, that behind the creation of the ghost namely Frankenstein, is one type of ghost. There are many types of ghost that may include the external ghost which was having its own appearance and they will have some special characteristics. The Internal ghost is that it will enter ones body and it will do some thing inside the body of the character. This is the kind of ghost and others include the vampire. Mostly all the thriller movies have this type of ghost, there will be a character sucking blood from the humans and using them for their existence. They will be more like humans living with them but they will have some special characteristics In the earlier periods the ghost will be only living inside the cave and later the living area of the ghost also increased ,no matter where the ghost are living- it may be at school, it may in our home or inside ones soul no matter where it will be. So we can go to the place as we wish when going for this kind of genre. And nowadays time is also not a matter for the ghost it may come at day time or it may come when we are sleeping and when we are in dream. The only fact is that vampire can roam around the world during day times. (Reference: www.darkwebonile.com )accessed on Book

Corporate Social Responsibility Essay -- Social Responsibility Essays

Business organizations regularly run into demands from various stakeholders groups when conducting day-to-day business. These demands are generated from employees, customers, suppliers, community groups, governments, and shareholders. Thus, according to Goodpaster, any person or group of people that can shape or can be shaped by attainment of the objectives by an organization is considered a stakeholder. Most business organizations recognize and understand their responsibilities to these groups and endeavor to honor and fulfill them. These responsibilities are often communicated to the public by a statement of principles or beliefs. For many business organizations, corporate social responsibility (CSR) has become an essential and integral part of their business. Thus, this paper discusses the two CSR views: the classical view and the stakeholder view. Furthermore, I believe that the stakeholder view has brought ethical concerns to the forefront of businesses, and an argument shall be made that businesses would improve both socially and economically if CSR, guided by God’s love, was integrated into their strategic planning. The classical view of CSR is a prominent ideology which business organizations are seen merely as profit-driven organizations. Simply put, businesses work for the sole purpose of making a profit. Thus, this profit motive is the sufficient and unique social identifier that separates a business organization from other institutions in society. These business organizations have a limited, yet essential role in society. Social concerns are considered important, but businesses, in the classical view, are focused solely on the economic activities and are judged accordingly. By having a limited role in society (i.e.,... ...oncerns to the forefront of businesses. In this paper I have suggested that business can improve both socially and economically by incorporating and integrating a CSR program, guided by God’s love, into their strategic planning. Strategic planning of CSR creates a mutual beneficial relationship between a community and a business organization. The community wins by having a business that is sensitive to their needs and responsive to their concerns, and the business wins by developing competitive advantage in the market that leads to long-term profitability. A business needs to incorporate God’s love when developing CSR policies in order to maintain the trust and the integrity of the relationship with the community. With solid strategic planning coupled with CSR, businesses can set the direction that provides the greatest benefit to themselves and communities.

Eating Disorders in Children

When the topic of body image and eating disorders is brought to a person’s attention, more times than not the idea of a self-conscious, thin adolescent girl comes to mind. However, reports have shown that children are exhibiting signs of lowered impressions of their own body and the presence of eating disorders are increasing at a younger age (Kedesdy, 2007). Very little is known about the commonness of eating disorders in pre-pubertal girls and boys. However, eating disorder specialists and programs in the United States are reporting an increase in young children who need help with related eating problems.According to the text book â€Å"Exploring Life Development†, in their attempt to reach â€Å"perfect† slimness, anoerexics lose between 25 and 50 percent of their body weight. (Katzman, 2005). The problem with body dissatisfaction is causing an increase in disordered eating and weight loss in young children. â€Å"Recent studies have shown that 42 % of first- , second- and third-grade girls want to be thinner; that 40 % of almost 500 fourth-graders surveyed said they diet â€Å"very often† or â€Å"sometimes†; and that 46 percent of 9-year-olds and 81 percent of 10-year-olds admit to dieting, binge eating or fear of getting fat† (Equit, M. Palmke, M. , Becker, N. , Moritz, A. , Becker, S. , & Gontard, A. , 2013). This essay will explore the development of eating disorders in children. It will show that these disorders are closely connected to a combination of physiological changes, environmental, and social factors. There are two types of eating disorders which are noted as being used to control food intake and result in extreme weight loss, Anorexia Nervosa and Bulimia. Anorexia is a condition in which a child refuses to eat adequate calories out of an intense and irrational fear of becoming fat.Bulimia is a condition in which a child binge eats and then purges the food by vomiting or using laxatives to prevent weigh t gain. Diagnosing a child with an eating disorder is difficult. It is hard for specialists and doctors to diagnosis school aged children for many reasons. The first reason is the frequent growth spurts in both height and weight that pre-pubertal children exhibit during this time in their life. Therefore, it is hard to measure an expected weight for a child at this age because all children are different. Children who do not gain weight around this age, but do grow in height are not always target for an eating disorder. This is the age which children are very active and participate in sports which may be the reason why they do not gain weight (Kedesy, 2007). In addition to the problems with the diagnosing children, specialists and physicians are not adequately trained to look for eating disorders in children. Problems with eating focus on picky eaters and issues of slow weight gain based on the stage of development for younger children. Physicians seldom consider that a child who is not eating may be linked to a problem with body dissatisfaction.It is more common to associate eating problems with the notion that the child is a picky eater rather than with them having an eating disorder. Children raised in a dysfunctional family are at higher risk for developing an eating disorder. A family life where there is physical or sexual abuse may result in a child turning to an eating disorder to gain a sense of control. Eating disorders are a child’s remedy. They help them deal with emotions and are especially prevalent in children who were raised in a home that did not allow feelings to be expressed.Research also shows that children are at a high risk for developing an eating disorder if their parents are preoccupied with appearance and weight. (Equit, M. , Palmke, M. , Becker, N. , Moritz, A. , Becker, S. , & Gontard, A. , 2013). If parents (or siblings) are constantly dieting and expressing dislike towards their own bodies, the child will receive the message that appearance is the most important thing to be concerned about. Society and the media also sends the message that being thin is the most important and necessary thing there is. Media is many things; media is education, knowledge, news, culture, corruption.This has been used as a form of pursing or influencing young children into believing that what they see is real. Commercials are used to tell children what to buy or what is â€Å"in†. There are several messages that that the media sends out to young children, some of them beneficial and some fraudulent. Women in particular have been portrayed to be flawless and tremendously thin, and if you are not then you must become flawless and thin. The textbook â€Å"Exploring Lifespan Development† mentions that this societal image of â€Å"thin is beautiful† contributes to the poor body image of many girls, specially early-maturing girls. (Tyrka, Graber, & Brooks-Gunn, 2000). Media messages have a great effect on you ng children that want to be liked and sadly enough they think that media is what matters. Some of these messages have resulted in young girls and boys going to the lengths of eating disorders to look like some of the messages they receive. Some children are more vulnerable to these messages than others. Children who are insecure about themselves or eager to please others are most likely to fall in to this horrible craze of being â€Å"thin and beautiful†.Children are bombarded with images and messages that reinforce the idea that thin is happy and successful. I believe it's important everyone, especially parents, are aware of these eating disorders. Most importantly, set an example for their children. Children learn by what they observe. If they are observing a healthy environment which is not focused on a negative body image with an emphasis on dieting, then they will be likely to follow the model set in place for them. An eating disorder is a very serious problem and needs to be treated as early as possible. It is important, as mentioned earlier to have treatment which includes the family.This is because the child’s eating disorder may be based on a problem which is deep seeded with in the family dynamics and also because of the child’s age. It is the initial approach to any problem with body image or eating disorder which is crucial for a person to recover and create a positive relationship with themselves and with food. Reports have also shown that 80% of girls in grades 3 – 6 have bad feelings about their bodies (Kedesdy, 2007). This issue of body dissatisfaction diverts the young child’s attention away from school work and from social interactions with peers.Preteen boys also worry about how their build compares with others. They are focused on sports and with the muscular men they see on television and have been conditioned to believe that muscles are more important than what is on the inside. The relevance of my findi ngs to modern society is that there are many extreme pressures existing in the world we live in, which directly affect a large number of the population to the point of extremity. In an age of high technology, rapid development, and intense social pressure, the pressure to be the best of the best prevails.Many people succumb to the pressure in a variety of ways, some beneficial, and some detrimental. Eating disorders such as Anorexia Nervosa and Bulimia in part result from an intense pressure to achieve the perfect ideal body weight and physical appearance. Emphasis on being perfect begins early in childhood and continues to grow with age, sometimes so much that a personality takes on a perfectionistic drive affecting every aspect of daily life. Perfectionism is a common individualized personality trait which in part stems from this ardent cultural pressure.

Simulation Of First Come First Served FCFS

Any modification on the scheduling algorithm will appear as modification on the operating system kernel code. Processor is an important source of CPU scheduling process, so it becomes very important on accomplishing of the operating system design goals. A delicate problem of the well-functioning of SO is the case when in CPU comes two or more processes which wants to be executed. Scheduling includes a range of mechanisms and policies that SO has to follows in order that all processes take the service.In this Paper we will discuss about two main batches algorithms, such as FCC and SF, and I will how a manner how to improve these algorithms in the future work. Keywords – CPU-Scheduling, Scheduler, OFFS, SF. 1. Introduction CPU scheduling is important because when we have multiple renewable processes, it can have a big effect on resource utilization and the overall performance of the system [2]. C.I Latency time: that is the time it takes for the dispatcher to stop one process an d start another running CPU scheduling deals with the problem of choosing a process from the ready queue to be executed by the CAP]. In a scheduling process is the responsibility of scheduler to determine when a recess moves from running state to waiting state also scheduler passes a process from the ready state to the execution state[J. In general waiting queues use FIFO and LIFO policies. We have two types of scheduling algorithms preemptive and non-preemptive.It's preemptive in those cases where the execution of a process can be interrupted by another process (which may have higher priority), while non-preemptive when a process takes control of the CPU and do not leave it until the end of execution The performance of scheduling is linked to several parameters: CPU Usage: CPU should be kept busy at 100% of time . 2. Throughput : Number of process that typically ends executing in the given moment of time . 3. Turnaround time: time which is necessary for the execution of a process. 4. Waiting time: it is time that a process must wait in queue ready to be executed. . Response time : is the time between the reception of the request made , to the first response . We have three types of schedulers: A-Long-term scheduler -? This type of scheduler decides which jobs or processes would be admitted to the ready queue. Also this Scheduler dictates what processes are to run on a system. B-Mid-term Scheduler – One second type scheduler it's mid-term scheduler who removes process from main memory and moves on secondary memory. C-Short-term Scheduler (also known as dispatcher) Dispatcher module gives control of the CPU to the process selected by the short-term scheduler.Characteristic for dispatcher is the. In order to have an optimal scheduling should be completed follows Eng conditions: 445 1 . CPU-usage – MAX 2. Throughput – Max 3. Turnaround time- MIN 4. Waiting time ; MIN 5. Response time -? MIN[6]. And this is illustrated in Figure 1 that is a fo ur state diagram of OFFS. Is an algorithm non-preemptive so if process take control of CPU and don't leave it until the end of execution. 2. Related Works The scheduler algorithms offer an endless field of study.I am focused on algorithms batch, I chose these algorithms because windows is very prevalent in my country and I think that this paper will help those who study windows as SO -What that concretely will deal in this paper is the simulation of two algorithms ( in order to compare them ) his topic well has studied by [2] on paper published in 201 1, it has become an excellent study from both theory and practice , Alkali Pant has achieved interesting conclusions regarding the: turnaround time, waiting time and response time time which has a great importance in batch systems.Another study that is very interesting is [1 3] , Jerry Breeches describes the way that we can get a process attached to a processor . Fig. 1: First Come First Serve Scheduling Figure 2 gives the flow chart o f PC'S in which the C code is supported , which we will use for simulation[4]. There is a simple structure hat represents the algorithm from the functional and construction. Processes are added one after another in the ready queue and executed in sequential order in time independently by the burst time they have [2].Another study in which based my paper is [1 2] . In this paper Minus Lee explains the problems that appear during scheduling process ,he treats the scheduling process improvement, reducing turnaround time ,waiting time response time and. According to the [1 2] different applications require different optimization criteria as example : batch systems (throughput, turnaround time) , interactive system (response time, fairness, user expectation) . Dry. R. B. Gar in his study [3] explains very clearly idea of scheduling through figures.Others studies that have studied very carefully are [1] , [4] and [6] which helped me to reach a clearer conclusion of waiting time which is i mportant in batches sister. This simulation will be carried through a C code. After I realize this simulation and I calculated the time needed for comparison I have describe a way to improve these algorithms by performance. 3. Theory of Experiment Below will give an overview of algorithms for both instruction and operation. This part will be accompanied by tables and figures to make clear how the functionality of these novo algorithms are. 3. F-CIFS OFFS is the simplest algorithm on batch systems as for the building as for the functioning. Policy that uses this algorithm is that FIFO, so the first process which requires CPU takes seen. ‘ice independently by the size of the process Fig. 2: First Come First Serve flow chart Below present the Gaunt diagram for the three processes for which we have calculated average time. 446 Table . 1 Process Execution Process Duration Order 0 Arrival Time 7 2 4 3 A scheduler adds on the top of the queue a process who has a short extenuation tim e and those who have longer extenuation time into the tail of the queue.This requires advanced knowledge or assumptions about the time needed to complete the process [1]. Fig. 3: Gaunt chart for First Come First Serve As we see from the Gaunt Chart : Pl waiting time -O PA waiting time = 20 PA waiting time = 27 The average waiting time =(0+20+7)/3=9 Advantages OFFS Is an algorithm relatively easy to understand and build, choosing of process for execution is very simple, enough to take the first in the queue and also the processes are added at the end of the queues. Fig. : Shortest First scheduling Basis for part Of the experiment will be the flow chart. At the flow chart of SF figure 5 is very clear the logic, processes will be executed after they are selected preliminarily. Disadvantages Through put is very low this because the long process want a long time to be executed, this leads to the so-called monopolizing of CPU.
