Relationship Between Spiritual Well-being and Happiness

Connection Between Spiritual Well-being and Happiness Presentation This part contains the rundown of the current examination, the ends drawn after the investigation of the information and the ramifications of the investigation. It likewise incorporates the impediments of the examination alongside the proposals for future exploration. Outline The motivation behind the examination was to look at the bliss of people scoring high on otherworldly prosperity and people scoring low on profound prosperity. Further, the investigation likewise investigated whether there were any critical sex contrasts in satisfaction just as profound prosperity. Arbitrary testing strategy was utilized to gather the example. The example was gathered from different post graduate universities and privately owned businesses in the city. First consent was looked for from the foundations to direct the exploration in their separate grounds. At that point the surveys were directed to the members. The example was managed two polls, so as to quantify the significant factors of the investigation. Otherworldliness was evaluated with the assistance of the Spiritual Well Being Questionnaire by Ellison Paloutzian (1982). Satisfaction was estimated utilizing the Subjective Happiness Scale by Lyubomirsky Lepper (1999). The example size was 222. To look at the satisfaction of people scoring high on otherworldly prosperity and people scoring low on profound prosperity, the complete example (N-222) was partitioned into two gatherings dependent on the scored acquired on the Spiritual Well Being Scale by Ellison Paloutzian (1982). Those people whose scores lay one SD over the mean (above 104.38) shaped the high gathering while those people whose scores lay one SD beneath the mean (below74.84) framed the low gathering. Therefore, the example comprised of 44 in the high and 37 in the low gathering (N=81). For considering the sexual orientation contrasts in joy and profound prosperity, the example involved 112 male and 110 females (N=222). The example had a place with the white collar class of society, from the age scope of 21 to 30 years old. It included unmarried people of various strict gatherings (Hindus, Muslims, Christians). It included understudies just as working experts living in Pune city. The base instructive capability of the example was twelfth grade. SPSS programming was utilized to investigate the acquired information. The autonomous examples T Test was utilized to analyze the gatherings on satisfaction and otherworldly prosperity. In light of the survey of applicable writing, the speculations of the current investigation were figured as: People who score high on profound prosperity will be fundamentally more joyful when contrasted with people who score low on otherworldly prosperity. There will be no critical distinction in bliss among guys and females. Ladies will score altogether higher on profound prosperity than guys. Ends The discoveries from the current examination can be finished up as follows: It was discovered that there was a huge contrast in satisfaction between people who scored high on profound prosperity when contrasted with people who scored low. The mean score of the high gathering was altogether higher on the variable of joy when contrasted with the mean score of the low gathering. Along these lines it tends to be inferred that people who score high on profound prosperity were more joyful when contrasted with people who score low on otherworldly prosperity. Sexual orientation contrasts were seen on joy. It was discovered that there was a noteworthy contrast in satisfaction among guys and females, with females scoring fundamentally higher on joy in correlation with guys. Thus, it very well may be presumed that ladies are more joyful in correlation with men. No sexual orientation contrasts were seen on the variable of profound prosperity. It was discovered that there was no noteworthy distinction in otherworldly prosperity among guys and females. Despite the fact that the mean score for ladies was higher, the thing that matters was not huge. Along these lines, it tends to be presumed that there are no critical sexual orientation contrasts on profound prosperity. Ramifications OF THE STUDY It was found from the current examination that people high on profound prosperity were more joyful in correlation people low on otherworldly prosperity and no sex contrasts were found in otherworldly prosperity. It was additionally discovered that ladies were more joyful than men. The investigation of sexual orientation contrasts is fundamental in seeing how various sexes react to various circumstances. Otherworldliness can be utilized in directing and helpful settings as a way of dealing with stress to upgrade psychological wellness. Moreover, the discoveries of the investigation have suggestions in the clinical field, where individuals with perilous infections can be instructed to adapt utilizing profound practices and procedures. The discoveries likewise can be utilized to make mindfulness and psycho-teaching individuals about the advantages of otherworldliness. Since otherworldly prosperity is connected with more prominent satisfaction, individuals can utilize profound strategies to improve their prosperity. Confinements One significant confinement in the correlation of people scoring high on otherworldly prosperity and people scoring low, was that sex was not controlled. There were more ladies (25) in the high gathering when contrasted with men (19). Then again there were increasingly male in the low gathering (22) than females (15). Lee, Seacombe Shehan in 1991 found that ladies were bound to report themselves as upbeat contrasted with men (Diener et al, 1999). Sex may have had an impact on the needy variable, joy. Another impediment of the examination was that the example size, for looking at bliss of people scoring high and low on otherworldly prosperity, was little. Subsequently it is hard to make clearing speculations. The strict connection of the example was not controlled. The example comprised of people having a place with various religions, for example, Hindu’s, Muslims and Christians. In any case, the three strict gatherings were not similarly spoken to. Hence, this turns into a constraint as religion may assume a job in an individual’s profound prosperity and joy. Further, different strict gatherings were excluded which additionally is a restriction. The age scope of the example was 21 to 30 years. Consequently, the outcomes may not appropriate to other age gatherings. The example included people having a place with the center layers of society living in a urban region in Pune city. In this manner, people from the lower and privileged of society just as those living in provincial territories were not viewed as which turns into an impediment as results may not substantial for these gatherings. Since self report inventories were utilized for acquiring the applicable information, social attractive quality and faking couldn't be controlled. This additionally turns into a confinement of the investigation. Recommendations FOR FUTURE RESEARCH In the current investigation sex was not controlled while looking at people scoring high on otherworldly prosperity and those scoring low on profound prosperity. Some exploration considers demonstrate that ladies are more joyful than men (Blanchflower and Oswald 2004; Frey and Stutzer 2002; Praag and Ferrer-I-Carbonell 2008 refered to in Tiefenbach and Kohlbacher,2013) while others recommend that men are the more joyful sex (Stevenson Wolfers, 2009 refered to in Compton Hoffman, 2011). Consequently it is prescribed to take equivalent number of guys and females so as to show signs of improvement comprehension of the connection among otherworldliness and joy. Further, it is recommended to think about the strict affiliations of the members by taking equivalent number of people from every strict gathering (Cohen, 2002). Likewise, strict minorities can be incorporated to build generalizability. Future examination can likewise consider diverse age gatherings, for example, moderately aged grown-ups and geriatric populace. Exploration has demonstrated that bliss diminishes from youth to middle age and afterward increments from middle age to mature age (Blanchflower Oswald, 2008 refered to in Carr, 2011). In this way, unique age gathering can be looked at on otherworldliness and satisfaction. Further examination can dig into different factors, for example, financial status, topographical area, conjugal status, family structure and study its relationship with otherworldliness and bliss in order to comprehend if these elements intercede the connection between the two factors.

The Oppression of Females in Advertising :: essays papers

Our general public is an intricate assortment of organizations, status, jobs, qualities, and standards, and the most ideal approach to comprehend and find out about them is using social curios. These can be anything from music to craftsmanship to writing, or as in the case of this conversation, the cutting edge formation of promotion as found in ladies' magazines. As Homo Sapiens moved from the tracker - gatherer lifestyle to modern culture , it was important to build a structure for living with the goal that such a concentrated number of individuals could exist together. This structure as come to comprise of a bunch of desires dependent on qualities and standards as jobs status and establishments. Alluring conduct is looked for by individuals all through the nation dependent on how one is raised and the desires one is barraged with consistently. These desires are reflected in all aspects of our way of life and are utilized by individuals in order to realize the proper behavior in so me random circumstance. The principle models are: the family, instruction, wellbeing and medication, religion, and the law. I have discovered that specific mediums mirror the normal jobs in these establishments superior to other people. I initially centered around sexual orientation jobs as a delineation of cliché conduct as reflected by publicizing particularly the depiction of ladies, however I found that there were different generalizations being sustained also that were similarly as standardized if not just less saw or contemplated. Along these lines, despite the fact that this contention will concentrate on the delineation of females and the female job in publicizing. It will likewise make reference to the general utilization of American qualities , standards, and foundations to impact shoppers. An organization is characterized as a steady bunch of qualities, standards, status, jobs, and gatherings that create around a fundamental social need with a status being an individual's situation in the public arena and a job being the conduct anticipated from that, and a worth being a socially shared thought of what is acceptable, right, and alluring and a standard being the conduct anticipated from those thoughts. At the point when individuals start to frame certain desires in life there start to be shaped generalizations. Individuals remember them generally and use them to shape assessments and act or not act with a specific goal in mind when they are gone up against with a circumstance or individual.

Using 5-HTP to Treat Depression

Using 5-HTP to Treat Depression Depression Treatment Medication Print Using 5-HTP to Treat Depression By Nancy Schimelpfening Nancy Schimelpfening, MS is the administrator for the non-profit depression support group Depression Sanctuary. Nancy has a lifetime of experience with depression, experiencing firsthand how devastating this illness can be. Learn about our editorial policy Nancy Schimelpfening Medically reviewed by Medically reviewed by Steven Gans, MD on August 05, 2016 Steven Gans, MD is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital. Learn about our Medical Review Board Steven Gans, MD Updated on February 04, 2020 Depression Overview Types Symptoms Causes & Risk Factors Diagnosis Treatment Coping ADA & Your Rights Depression in Kids Tetra Images - Jamie Grill/Brand X Pictures/Getty Images In This Article Table of Contents Expand Overview Symptoms 5-HTP Effectiveness   Safety and Side Effects   Pregnancy and Breastfeeding View All Research shows that using 5-HTP for depression may help alleviate depressive symptoms. 5-HTP, or 5-hydroxytryptophan, is an amino acid that our bodies produce from a dietary amino acid called l-tryptophan. It can be converted into the mood-regulating neurotransmitter called serotonin, as well as the sleep-inducing hormone known as melatonin. 5-HTP may also be synthesized in the laboratory by extracting it from the seeds of the plant ?Griffonia simplicifolia.?? Understanding Depression Depression, which is also referred to as clinical depression or major depressive disorder, is a mood disorder that creates feelings of sadness and hopelessness that can last for a long period of time.?? Eventually, it starts to creep into your everyday life, affecting the way you think, how you deal with stress, the way you behave, and how you feel. Your regular activities of daily life, like getting out of bed, brushing your teeth, and showering may feel pointless and overwhelming. Your energy may feel sapped too, making it even easier to skip these small tasks. Depression is more than the normal funk we all find ourselves in sometimes. The key to knowing its time to find help is determining when your symptoms are bad enough that theyre seriously impacting your life. Maybe youve stopped participating in activities you once enjoyed. Or maybe you find yourself sobbing on the bathroom floor all too often. Perhaps you dont even recognize yourself anymore as you hazily go through the motions of just barely living. You may have depression only once, but many people who deal with depression have multiple episodes during their lifetimes. Keep in mind that depression isnt a personal flaw. Its a real medical condition that needs to be treated, and depending on the severity of your depression, the treatment may end up being a long-term process. Take heart thoughâ€"the majority of people who have dealt with depression report feeling better once they start on medication, go to psychotherapy (counseling), or do a combination of both. Depression Symptoms Symptoms of depression are present during the majority of the day, just about every day, for two weeks or more and may include:?? Feeling sad, hopeless, or emptyCrying more than usualAnger or irritabilitySleeping too much or not sleeping enoughLoss of interest in normal activities or hobbiesFatigueLoss of energyAppetite changes, such as eating more or less than usualWeight changes as a result of appetite changesAnxietyFeeling worthless, guilty, and/or isolatedDifficulty concentratingMemory problemsFeeling agitated or restlessThinking about death and/or suicidePhysical symptoms like unexplained headaches, backaches, or stomachaches How  5-HTP Works The essential amino acid l-tryptophan can be obtained by eating foods that contain it, such as red meat and turkey, but its ability to be converted into 5-HTPâ€"and ultimately into serotoninâ€"is limited by the availability of an enzyme called tryptophan hydroxylase.?? The amount of tryptophan hydroxylase in our bodies can be inhibited by many different factors, such as stress, insulin resistance, vitamin B6 deficiency, and magnesium deficiency. Supplementing with 5-HTP overcomes this problem by eliminating the need to convert l-tryptophan to 5-HTP, thus allowing more 5-HTP to be available for conversion to serotonin. Effectiveness   Overall, the clinical trials published to date indicate that 5-HTP may be effective in treating depression symptoms, both on its own and when used in conjunction with prescription antidepressants.?? However, better quality studies are needed to firmly establish its effectiveness, especially since they have only been done in small groups of people. One study concluded that 5-HTP shouldnt be given by itself because its not very effective and it may actually deplete neurotransmitters in your brain like dopamine and norepinephrine, which can make your depression worse.?? Instead, the researchers noted, 5-HTP should be given with dopamine or serotonin amino acid precursors in order to minimize side effects, prevent neurotransmitter depletion, and to get the most efficacy from 5-HTP. However, these supplemental amino acids need to be kept in careful balance or theres a risk of depression symptoms becoming worse due to neurotransmitter depletion. A group of researchers who looked at the effects of 5-HTP in a slow-release form argue that this extended delivery method could make the supplement an important adjunctive (additional) therapy in people who have treatment-resistant depression.?? To support their beliefs, the researchers also did a related study on the performance of slow-release 5-HTP versus the immediate release formula in mice, which showed that the slow-release version was far more therapeutically effective. The scientists conclude that developing a slow-release 5-HTP drug is doable and could be a particularly beneficial treatment for patients who appear to have 5-HT deficiencies, typically indicated by suicidal actions, severe depression, and co-occurring borderline personality disorder (BPD), all of which tend to be more resistant to SSRIs. Additionally, the researchers believe that slow-release 5-HTP could potentially help people who have been diagnosed with mental health disorders that are only partially responsive to SSRIs like obsessive-compulsive disorder (OCD) and anxiety disorders. Safety and Side Effects   Doses of around 200 to 300 mg per day of 5-HTP seem to be fairly well-tolerated.?? The most common side effects reported with 5-HTP include nausea, vomiting, and diarrhea. Less common side effects include a headache, insomnia, and heart palpitations. Gastrointestinal side effects appear to be dose-dependent and tend to lessen over time. There is one very serious safety concern with 5-HTP, however. When taken in conjunction with other medications for depression that also increase serotonin, such as SSRIs or monoamine oxidase inhibitors (MAOIs), there is a possibility that your serotonin levels may become dangerously high.?? This condition, called serotonin syndrome, leads to symptoms such as high blood pressure, hyperthermia, flushing, hyperreflexia, dizziness, disorientation, and involuntary muscle twitching called myoclonus. Patients experiencing these symptoms should seek immediate medical attention, as this condition can be fatal. Pregnancy and Breastfeeding There is not currently enough data to tell whether 5-HTP is safe for pregnant and breastfeeding women to use. For this reason, you shouldnt take 5-HTP if youre expecting a child or nursing. A Word From Verywell Although you can buy it over-the-counter, talk to your doctor before starting on 5-HTP, especially if youre already taking other antidepressants or medications. Your doctor can make sure youre taking the right amount and that youre not susceptible to any potential drug interactions. The 7 Best Online Help Resources for Depression

The Carbon Chemistry and Crystal Structure of Diamonds

The word diamond is derived from the Greek word adamao, meaning I tame or I subdue or the related word adamas, which means hardest steel or hardest substance. Everyone knows diamonds are hard and beautiful, but did you know a diamond could be the oldest material you might own? While the rock in which diamonds are found may be 50 to 1,600 million years old, the diamonds themselves are approximately 3.3 billion years old. This discrepancy comes from the fact that the volcanic magma that solidifies into rock, where diamonds are found did not create them, but only transported the diamonds from the Earths mantle to the surface. Diamonds also may form under the high pressures and temperatures at the site of meteorite impacts. The diamonds formed during an impact may be relatively young, but some meteorites contain stardust — debris from the death of a star — which may include diamond crystals. One such meteorite is known to contain tiny diamonds over 5 billion years old. These diamonds are older than our solar system. Start with Carbon Understanding the chemistry of a diamond requires a basic knowledge of the element carbon. A neutral carbon atom has six protons and six neutrons in its nucleus, balanced by six electrons. The electron shell configuration of carbon is 1s22s22p2. Carbon has a valence of ​four since four electrons can be accepted to fill the 2p orbital. Diamond is made up of repeating units of carbon atoms joined to four other carbon atoms via the strongest chemical linkage, covalent bonds. Each carbon atom is in a rigid tetrahedral network where it is equidistant from its neighboring carbon atoms. The structural unit of diamond consists of eight atoms, fundamentally arranged in a cube. This network is very stable and rigid, which is why diamonds are so very hard and have a high melting point. Virtually all carbon on Earth comes from the stars. Studying the isotopic ratio of the carbon in a diamond makes it possible to trace the history of the carbon. For example, at the earths surface, the ratio of isotopes carbon-12 and carbon-13 is slightly different from that of stardust. Also, certain biological processes actively sort carbon isotopes according to mass, so the isotopic ratio of carbon that has been in living things is different from that of the Earth or the stars. Therefore, it is known that the carbon for most natural diamonds comes most recently from the mantle, but the carbon for a few diamonds is the recycled carbon of microorganisms, formed into diamonds by the earths crust via plate tectonics. Some minute diamonds that are generated by meteorites are from carbon available at the site of impact; some diamond crystals within meteorites are still fresh from the stars. Crystal Structure The crystal structure of a diamond is a face-centered cubic or FCC lattice. Each carbon atom joins four other carbon atoms in regular tetrahedrons (triangular prisms). Based on the cubic form and its highly symmetrical arrangement of atoms, diamond crystals can develop into several different shapes, known as crystal habits. The most common crystal habit is the eight-sided octahedron or diamond shape. Diamond crystals can also form cubes, dodecahedra, and combinations of these shapes. Except for two shape classes, these structures are manifestations of the cubic crystal system. One exception is the flat form called a macle, which is really a composite crystal, and the other exception is the class of etched crystals, which have rounded surfaces and may have elongated shapes. Real diamond crystals dont have completely smooth faces but may have raised or indented triangular growths called trigons. Diamonds have perfect cleavage in four different directions, meaning a diamond will separat e neatly along these directions rather than break in a jagged manner. The lines of cleavage result from the diamond crystal having fewer chemical bonds along the plane of its octahedral face than in other directions. Diamond cutters take advantage of lines of cleavage to facet gemstones. Graphite is only a few electron volts more stable than diamond, but the activation barrier for conversion requires almost as much energy as destroying the entire lattice and rebuilding it. Therefore, once the diamond is formed, it will not reconvert back to graphite because the barrier is too high. Diamonds are said to be metastable since they are kinetically rather than thermodynamically stable. Under the high pressure and temperature conditions needed to form a diamond, its form is actually more stable than graphite, and so over millions of years, carbonaceous deposits may slowly crystallize into diamonds.

Hesss Law Definition - Chemistry Glossary

Hesss law states that the energy change in an overall chemical reaction is equal to the sum of the energy changes in the individual reactions comprising it. In other words, the enthalpy change of a chemical reaction (the heat of reaction at constant pressure) does not depend on the pathway between the initial and final states. The law is a variation of the first law of thermodynamics and conservation of energy. Importance of Hesss Law Because Hesss law holds true, its possible to break a chemical reaction into multiple steps and use the standard enthalpies of formation to find the overall energy of a chemical reaction. Standard enthalpy tables are compiled from empirical data, usually acquired using calorimetry. Using these tables, its possible to calculate whether or not a more complex reaction is thermodynamically favorable or not. Applications of Hesss Law In addition to calculating the enthalpy of a reaction rather than directly measuring it, Hesss law is used to: Find electron affinities based on theoretical lattice energy.Calculate heat change of phase transitions.Calculate heat change when a substance changes allotropes.Find the heat of formation of an unstable intermediate in a reaction.Find the lattice energy of ionic compounds.

Cry the Beloved Country, Inherit the Wind, Julius Caesar Free Essays

Eleanor Roosevelt stated that people make their own decisions, and the reasoning behind what happens in their lives is of their own responsibility and consequence. Bert Cates, from Jerome Lawrence’s Inherit the Wind, applies directly to this statement while Stephen Kumalo of Cry the Beloved Country and Caesar of Julius Caesar do not. Stephen Kumalo and Julius Caesar’s lives were drastically influenced by the choices of others, not their own. We will write a custom essay sample on Cry the Beloved Country, Inherit the Wind, Julius Caesar or any similar topic only for you Order Now Bertram Cates, however, made his own decisions and influenced his life individually. In Inherit the Wind, Bert Cates illegally teaches evolution to his biology class. As a citizen of Hillsboro, TN, he must have known that teaching evolution was unlawful as well as the consequences that would follow. Cates, however, is a man who wants to fully educate his students and open them up to different ideas and perspectives. For this reason, he teaches evolution anyway and is prosecuted and fined $100 (Lawrence, . Inherit the Wind. Pg 103) for it. It’s a consequence of his choice to teach such a controversial subject and because of it his life is greatly impacted. In Julius Caesar, Julius’ fate was definitely not of his own choice. Brutus, Cassius, Cinna, Decius, and Casca, a group of people Caesar trusted, murder him. Caesar had done nothing wrong. He’s a bit cocky and self centered at times, perhaps, but he has done nothing harmful to the well-being of others. The lack of trust from Brutus, Cassius, Cinna, Decius, and Casca is why Caesar’s life is brought to an end. They think he’d go mad with power, so they take him out before he even has the chance to prove them right or wrong. In reality, he would have done what is right for his people, and that is apparent in his will. â€Å"To every Roman citizen he gives, to every several man, seventy-five drachmas. †, Marc Antony reads off of Caesar’s will, â€Å"Moreover, he hath left you all his walks, private arbors, and new-planted orchards, on his side Tiber. He hath left them to you and to your heirs forever. † (Shakespeare, Julius Caesar. Pg. 133) Caesar has no control over stopping the situation because he doesn’t even know it’s going to happen. He hasn’t done anything to deserve his murder, it’s not of his own consequence. He was killed out of the mistrust from others. Stephen Kumalo of Cry the Beloved Country is tossed around, put through so much pain, and none of it is of his doing. He may have made the decision to look for his son and sister to protect his family, but isn’t it a man’s instinct to care for the people who are closest to him? Stephen’s son made the decision to take the wrong path, live the life of a thief, and eventually kill another person. Stephen’s sister made the decision to sell alcohol, sleep around, and not care for her son. All of these bad choices were made by other people, yet Stephen was still strongly affected by them. Eleanor Roosevelt says that people are responsible for what happens in their lives, but Stephen couldn’t control Absalom being sentenced to death, Gertrude leaving, or his brother screwing him over. This is because he didn’t have the money, power, and most importantly, the control over their decisions. How to cite Cry the Beloved Country, Inherit the Wind, Julius Caesar, Essay examples

Pulse Width Modulation Final Year Project Essay Example

Pulse Width Modulation Final Year Project Paper Chapter 1 Introduction 1. 0 Background Pulse Width Modulation (PWM) is a type of devices that can be used as a DC motor speed controller or light dimmer. PWM is used extensively for speed controller where power-saving application is needed. This device has been used as a motor speed control for small DC fans, for example in computer power supplies. A PWM circuits works by creating a square wave with a variable on-to-off ratio, the average on time may be varied from 0 to 100 duty cycle. The term duty cycle describes the proportion of on time to the regular interval or period of time; a low duty cycle corresponds to low power, because the power is off for most of the time. Duty cycle is expressed in percent, 100% being fully on. From this, a variable amount of power is transferred to the load. The main advantage of PWM is that power loss in the switching devices is very low. When the switch is off there is practically no current, and when it is on, there is almost no voltage drop across the switch. Power loss, being the product of voltage and current, is thus in both cases close to zero. PWM also works well with digital controls, which, because of their on/off nature, can easily set the needed duty cycle. Additional advantage of PWM is that the pulses reach the full supply voltage and will produce more torque in a motor by being able to overcome the internal motor resistance easily. 1. 1 Objectives The objectives of this project are: 1. To develop the actual circuit of the PWM. 2. To simulate the PWM circuit in simulation software. 3. To use the PWM in order to control the speed of the DC motor. 1. 2 Methodology Start Title consideration, ideas Supervisor approval Components specifications and data sheets Proposal Drafting Proposal Evaluation Project Simulation Project Presentation Progress Report Submission END Figure 1. 2. 1 Flowchart of Methodology 1. 3 Gantt Chart 1. 3. 1 Final Year Project 1 | WEEKS| We will write a custom essay sample on Pulse Width Modulation Final Year Project specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Pulse Width Modulation Final Year Project specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Pulse Width Modulation Final Year Project specifically for you FOR ONLY $16.38 $13.9/page Hire Writer ACTIVITY| 1| 2| 3| 4| 5| 6| 7| 8| 9| 10| 11| 12| 13| 14| 1| Student-supervisor-panel allocation, briefing about FYP, introductions| Â  | Â  | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 2| Student-supervisor meeting arrange time, finding ideas discuss ideas, project titles| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 3| Student-supervisor regular meeting| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 4| Proposal preparation| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 5| Proposal evaluation, meet supervisor for evaluation, things to be improved| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 6| Proposal correction correct any mistakes| Â  | Â  | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 7| Project Development choose circuit, check availability simulation| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 8| Proposal and progress presentation| Â  | Â  | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 9| Progress report writing is based on progress| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 10| Progress report submission submit report| Â  | Â  | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 1. 3. 2 Final Year Project 2 Week| 1| 2| 3| 4| 5| 6| 7| 8| 9| 10| 11| 12| 13| 14| Tasks| | | | | | | | | | | | | | | Buy Components | Â  | Â  | Â  | Â  | | | | | | | | | | | Construct circuiton breadboard | | | Â  | Â  | Â  | | | | | | | | | | Troubleshoot| | | Â  | Â  | Â  | | Â  | Â  | | | | | | | PCB Layout Design| | | | | | Â  | | | Â  | | | | | | PCB Layout Print| | | | | | | | | | Â  | Â  | | | | Soldering| | | | | | Â  | Â  | Â  | | | | | | | Final Report| | | | | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Final Presentation| | | | | | | | | | | | | | | 1. 3. 2. 1 Aims for Final Year Project 2 1.

Troubleshoot 1. 3. 2. 2 Project planning for Final Year Project 2 For the final year project 2, we have to prepare the actual circuit based on our simulation result. We will create the PCB artwork with PCB programming such as ExpressPCB, which is available for free and is surprisingly functional. Next, we have to print out the PCB artwork on a transparency. Then we cut out the printed portion of the artwork. This will define the size and shape of the PCB. To make PCBs, we can use the UV exposure method, which is only slightly more difficult than and significantly more precise than the toner transfer method. To start out, we must cut the PCB to be the same size as the outline of the PCB positive. First, we drew a rectangle the same dimensions of the PCB on the protective layer of UV Reactive copper covered ibreglass board, and then cut it out using a Dremel tool equipped with a diamond wheel. We have to make sure that once we have removed the board from its protective package it will not be exposed to any UV. Fluorescent and halogen lights both output enough UV light that they will expose the board through the protective layer of plastic. Next, after we cut the UV sensitive PCB to size, we are ready to expose the board. Then we remove the protective layer to size, from the PCB right before we place the positive on it, or else dust particles will attach to the board, which will mark the final PCB. To expose the PCB, first remove the protective layer, place the positive transparency on top of the board, and place it in the UV exposure box. An exposure time of 10-11 minutes is recommended. Now we need to drill holes in the PCB for the through-hole components. Finally, we have to solder all the components through-hole components. If the final result is not achieved when testing the final circuit, we have to run troubleshooting and find out the problem. Then, we solved the problem based on the troubleshooting after we identify the real problem.

A modulated square will be generated from the second IC. This wave of current will be amplified by IRF521 and then went to the motor and spin it. The DC motor speed will depends on the magnitude of the current. Chapter 3 Project Progress 3. 0 The Project Progress and the Project Outcomes The first stage of the progress is building the circuit for the Pulse Width Modulation (PWM) circuit. Then, the best circuit diagram is chosen for our project. A preliminary literature review about our circuit had also been done. In this project, two of the LM556, Dual 556 Timer TTL IC were used to simulate the PWM circuit. The first IC allowed the possibility to generate square wave while the second IC allow modulation variation. Other than that, several problems were encountered when simulating some part of the circuit. This is due to incomplete library component of the simulation software such as the lack of LM556 IC in the first place. This was because the wrong type of licence of the software was selected. After a few trials and some changes of the circuit diagram for simulation, and with the right licence for the software, the PWM circuit was successfully simulated.

Chapter 4 4. 0 The Problems Encountered CASE 1 – FINDING SUITABLE SIMULATION SOFTWARE The PWM circuit uses two of LM556 IC. The first LM556 will convert DC input signal into square wave. Before doi ng the hardware of the project, the software need to be simulated first to check whether the circuit diagram is correct or need some adjustment. Because of this, finding the suitable simulation software had become a problem encounter to finish the project. List below show example name of other simulation software that can be used to run any the software simulation for the project; 1. TINA 2. OrCAD Capture 3. PROTEUS All of the other simulation software above can be use to run the simulation for this project but some of them were not suitable. As an example the TINA software were not used because of the unfamiliarity and the complexity of the software. The project also cannot be simulated using the OrCAD Capture since there were a large number of library which does not have simulation installed. This make it unsuitable since this project required to be simulated. Meanwhile PROTEUS software was not used because of the difficult interface that complicate the user or in other words not user-friendly. CASE 2 – WRONG LICENCE OF SIMULATION SOFTWARE After MULTISIM had been installed, a situation was encountered where the library components are not complete or some of the components are not available. If this problem prolonged, the circuit cannot be designed in the software. Some measures had been taken to find the solution but the problems still persist. There are some types of licence that accompanied for MULTISIM, which are: 1Power PRO Edition 2Full Edition 3Student Edition 4Education PKG Edition 5Base Edition At first, the Full Edition licence was installed. When the circuit was being designed, a lot of components were unavailable. Every aspect of the software was checked, but no problem related to the software was detected. The MULTISIM software was cleanly installed in the computer. . 1 Solutions for Every Problem CASE 1 SOLUTION – USE MULTISIM SOFTWARE The simulation can be done by using simulation programmed like TINA, Proteus, or OrCAD Capture. Unfortunately, all of these simulation programmed mentioned above have problems as explained before. Without a proper simulation, it is hard to detect any problems that exist in the design of the circuit. Finally, MULTISIM i s chosen as the simulation program. MULTISIM was suitable for simulation of the Pulse Width Modulation circuit. MULTISIM has all the required components in its component library. Hence, all the components can be place in the circuit to complete it. Simulation can be done easily by using MULTISIM. All the results being cleared by using this programmed. Expected results are the PWM wave which will control the motor. CASE 2 SOLUTION – WRONG LICENCE OF SIMULATION SOFTWARE This problem was easily encountered by reinstalling licence of the right type. In this case, PowerPro Edition licence type was required. After it has been reinstalled, all the components are unlocked. Hence, the process of designing the circuit in the simulation software continued, and simulation process succeed. Chapter 5 Conclusion For this semester, the project progress was successful until the simulation. Hence, the simulation needs to be done correctly according to the circuit so that expected result can be obtained. The circuit diagram for PWM to Control DC Motor Speed has been successfully designed. Thus, the first objective has been achieved. The progress of the project works efficiently if the project followed accordingly to the Gantt chart made at the beginning of the project. The Gantt chart contains all the important steps that need to be followed in rder to finish the project successfully. All the steps in the Gantt chart been mentioned with respective date. Hence, there should be no problem during Final Year Project 1 when all works were being done according directly to the Gantt chart. The simulation for PWM to Control DC Motor Speed had been done by using simulation program, MULTISIM. MULTISIM provides all the necessary components to complete the simulation for the PWM circuit . Since the output should be a DC motor or a DC fan, it was replaced with Oscilloscope or Multimeter to observe the changes that occur in the simulation. This shows that choosing MULTISIM is the smart choice to run the simulation because of the advantages and the ease of use that this simulation program has. REFERENCES 1.
