Software Engineering - Essay Example Some of them are Waterfall model, Spiral Model, Rapid Application Development (RAD) model, Prototyping model, Incremental Model, Concurrent Development Model, Component-based model, Formal Methods model and Fourth Generation Techniques. All these models describe different processes that are used for development of software. Generally for new types of applications, Waterfall model, Spiral Model, Rapid Application Development (RAD) model and Prototyping model are not yet so standardised. For these types of application new models such as Incremental Model, Concurrent Development Model, Component-based model, Formal Methods model and Fourth Generation Techniques is commonly used with the combination with previous mentioned methodologies. These all methods provide the technical specifications for building software. They encompass a broad group of tasks that include requirements analysis, design, program construction (coding), testing, and support. These all tasks are performed for development of software. Next section will cover some commonly used software development methods with advantages/ disadvantages, and where it can be used for development of software (or applications). The Waterfall Model: It is also called as Software Development Life Cycle (SDLC) or Linear Sequential Model. It is the oldest and the most widely used paradigm for software engineering. The waterfall method attempts to pin down the requirements early in the project life cycle. After gathering requirements, software design is performed in full. Once the design is complete, the software is implemented. The Waterfall model suggests a systematic, sequential approach to software development that begins at the system level and progresses through analysis, design, coding, testing, and support. [Pressmen 2001] Software is integral part of a larger system or business; therefore initially requirements for

Natural rights in John Lockes, the second treatise on government Essay

Natural rights in John Lockes, the second treatise on government - Essay Example As such, everyone is entitled to enforce natural law in order to uphold these rights. Secondly, he purports that as an individual ventures into societal relationship with others, he trades what goods he possesses for goods he does not, and as such forms a reason to formulate methods to facilitate the trade of goods, such as the use of money, since money is non-perishable in contrast with food. As such, when money is injected into the system, individuals may pertain to give up their natural rights in order to be governed by a select group of people who exist solely to protect their welfare and property. These representatives work by introducing a system of laws and rules that expand over the societies they govern, and are in charge of enforcing them. However, they must only adhere to the interests of the societies at large, and hence, are at the complete disposal of the individuals and are subject to replacement at the people’s discretion. Locke thus emphasizes a Laissez Faire style of government which respects tolerance and moral values announced by natural rights than a strict measure of communism or monarchy. His political ideology promotes distinct sense of social awareness and respect by all of natural law. Argument against John Locke’s theories Locke’s focus on individual precedence over societal matters suggests two things. The first pertains to the regulation of civil society in that the people realize a need for preservation of their material belongings such as house and property, a measure they cannot administer individually by way of natural right as that might render their judgement partial and unjust. As such, they resort to giving up their natural rights so a body of executives can adjudicate on their behalf. This is because if individuals resorted to upholding their natural rights themselves against those who wronged them, only the strongest would survive. By letting an executive handle the adjudication for them, the judgement is deemed impartial. Of course, in conjunction with this right, Locke states that every child is born free, independent and pure, â€Å"a subject of no country or government† (Locke 118). However, in order to be respectful of other’s rights he must first attain majority and then make an informed decision as to which community he must partake in, for being part of one would mean his giving up of some natural rights in order to follow the customs of the community. Thus, before he attains that majority, the child is essentially without affiliation, under the care of his father, and rendered â€Å"stateless in the very state he was born† (Klausen 763). This gives rise to patriarchy which defines the child’s governing system resulting from tacit consent. Moreover, Locke suggests that tacit consent is binding on the individual as it forms part of his contract within the community he is born, but as the child grows up into majority, he is allowed to leave the p atriarchy to which he has adhered and choose a community to consensually give up his natural rights to. This effectively declares tacit consent as NOT binding. Moreover, Locke’s policy of independence and attainment of natural liberty is only possible if there is â€Å"

Assessment of physical workload in boiler operations Assignment - 1

Assessment of physical workload in boiler operations - Assignment Example These were used as indicators for quantifying physical labour that such operators experienced. In this case, Justino et al (4) had to use a number of instruments to measure the heart rate, places of higher overload, pain in certain parts of the operators’ body, and physical workload. These instruments included heart rate monitor, which was utilised to measure the heart rate, the tape measure for marking the key points where operators of the boiler remained during the process of boiler operation, the Infrared digital camera for showing the areas that experienced higher incidence of thermal radiations within the body of operators, the heart rate meter for recording the operator’s heartbeat, the painful Areas Diagram and Nordic questionnaire for collecting information regarding pain experienced by operators, and the wet-bulb globe thermometer (WBGT) for recording thermal temperatures, which in turn helped ascertain places of higher thermal overload. To measure pain, a diagram, in this case, human body was divided into 24 segments. Was followed was to evaluate these body parts to ascertain areas that the operators experienced pain. This was done by evaluating subjectively, with the use of a scale ranging from zero to seven, the level of discomfort experienced in each of the 24 segments. In measuring the heart beats, the heart rate meter, which consisted of three parts: transmitter, digital pulse receiver, and an electrode elastic strap, was used. This way, a transmitter was fixed in the chest of the operator to enable the heart beats to be captured and stored within the wrist receiver. In order to ascertain which parts of the body experienced higher thermal overload, a tape measure was used to mark key areas that an operator remained while carrying out the boiling operations. The wet-bulb globe thermometer (WBGT) was then used to

Ethnic Conflict Essay Example for Free

Ethnic Conflict Essay 2. Discuss the effect that modernization has had on ethnic identification and ethnic conflict. The effect modernization has had on ethnic identification and ethnic conflict is not a great one. Early modernization theorists, who were quite optimistic about the positive effects of literacy, urbanization, and modern values, clearly underestimated the extent to which these factors might mobilize various ethnic groups and set them against each other (Handelman, 2011, p. 113). Modernization challenged traditional religious, national, and tribal identities by undercutting traditional ethnic practices and values. A huge part of current modernization is globalization, which pose an even greater challenge. The long-term effect of the expanding â€Å"world culture† advanced by globalization are not entirely clear (Handelman, 2011, p. 114). Globalized culture can create a backlash and increase tensions between neighboring communities as not everyone can ethically identify with each other. 3. What are some reasons that might explain why major civil strife related to ethnicity has declined in the last 10-15 years? Some reasons that might explain why major civil strife related to ethnicity has declined in the last 10-15 years are statecraft, constitutional arrangements and external intervention. In addition, the transition to a democratic government has aided in the decline. Faced with common critical environmental, social and economic matters for the previous 10 to 15 years, different ethnic groups came to what socialist have called a culture of accommodation. Accommodation is the practice which contradictory groups make a mindful attempt to make working arrangements with in them which then suspend the conflict and make their relations more acceptable and reduce wasteful energy.

Art Projects: Drawing a Partridge and Crayon Art

Art Projects: Drawing a Partridge and Crayon Art How to draw a partridge in a pear tree How to seal a pendant colored with melted crayon shavings How can I make a bracelet out of DMC floss? HOW TO DRAW A PARTRIDGE IN A PEAR TREE The topic that this article is going to focus on is about a bird which is not so famous but means a lot when people come across occasions like Christmas. Many must not have heard about this bird and those who have heard it might recollect it from the phrase, Partridge in a Pear tree. Lets now get to know more about this bird and the meaning behind the phrase. In short, lets draw a partridge to our attention which is generally referred in context with a pear tree. A partridge is basically a bird belonging to the pheasant family also called as Phasianidae. They are non-migratory, medium-sized birds which are native to Europe, Africa and Asia. They are ground-nesting birds which are involved mainly in the seed-eating livelihood. These details must have given the readers enough information about a brief outlook of a partridge. But these details matter more to a biologist rather than general readers. The specialty of this bird is that, it has a unique relationship with the pear tree. Christians must be probably aware of the phrase, i.e. to draw a partridge to a pear tree, because the event takes place in Christmas. Partridge in a pear tree is actually a stocking kit from Bucilla which features a beautiful partridge nestled in a tree. To draw a partridge in a pear tree implies decorating the Christmas tree with a stocking which contains a partridge in a pear tree surrounded by glittering golden pears. To draw such a thing on a Christmas tree pleases Santa Claus and the tree glitters even more. The things need to create a partridge in a pear tree are sequins, beads, needles, cotton floss, metallic threads, stamped felts and glitter for shining. The stocking should be approximately 18 long diagonally and must display a partridge bird on a tree with pears around it. This is the way in which the stocking is created. There are several interpretations about the partridge in a pear tree phrase. One implication is that, it is a Christmas song which depicts the love between two persons by offering the partridge in a pear tree gift to each other. Another story behind this topic is known world wide. Partridge has been named from the Greek word, Perdix which was once the name of a Greek king. This king was once cast from a tower into the ocean by his enemy and he emerged as a bird from there and was carried to heaven by Goddess Athena. Thus, Athena represents the pear tree which was responsible for carrying the bird Perdix which is called partridge, to heaven. Thus sometimes, the bird, partridge was also referred as a symbol of Jesus Christ and thus the Christmas carol containing the phrase was formed. These two instances clearly tell us how Christians believe in the partridge in the pear tree and wait to draw a partridge each Christmas. Thus, the readers must have gained a spectacular piece of mythological history which is followed throughout the world each Christmas, when people around the world get ready to draw a partridge in the pear tree. It also takes us to a bright moral that, occasions like these get focused only when they are followed regularly. BEST BRAND/TYPE OF TRANSFER PAPER FOR EMBROIDERY OR CREWEL WORKS Art and Craft form the major part of the creation industry. This industry is mainly based on the skills of the artists to imagine, design and create. While in school days everyone is taught a bit of art and craft, some like it, some dont. The days are greatly remembered when the tracing paper was used as the means of creating an exact copy of the image mechanically before printers came into existence. Transfer papers are also of the same kind as tracing papers and also have the same purpose. Many creative things can be done using this transfer paper such as, printing on t-shirts, designs on pots and many more. But the purpose that surprises many is the use of transfer paper for embroidery. The task seems new as the traditional method of doing embroidery on cloth articles was with a needle and many colorful threads. Earlier the design to be made was sketched with a pencil roughly onto the cloth and then the thread was used to give it an outline. Now-a-days, the free-hand sketching has been made more perfect by the use of transfer paper. The best quality transfer paper gives astonishing results and gives the impression of a perfect design. The process of using transfer paper for embroidery can be explained briefly as follows. Inkjet or any other printer is first used to print the image on the transfer paper. This image can then be transferred onto the clothing by a heat press. This process is also called as an iron-on. The image once transferred can be embedded in the cloth by the use of embroidery. There are several types and brands of transfer papers available in the market. These can be named as, heat transfer paper, inkjet transfer paper, sublimation transfer paper, color laser transfer paper etc. Each of them has their own advantages and disadvantages. The most expensive one is the color laser transfer paper. It seems the names of the transfer papers belong to the names of the printers they are used with. Inkjet transfer paper comes in two varieties, for light colored fabric and for dark colored fabric. The fabrics which are going to be used for printing need to be of good quality to increase the life of the print on it. Use of transfer paper for embroidery is an exciting option for creating and printing various designs on the fabric using the various transfer papers. This is a new fashion of clothing which is growing at a rapid pace in the fashion industry. This act of using transfer paper for embroidery on the clothes prompts the designers to try the process at home or open centers for such printing works. The embroidery which seemed boring for so many years will finally be retrieved in a new form and the clothes wore will have the designs made by the person wearing it. The important suggestion is to select the proper and the best type of printing and embroidery technique and last but not the least the best brand and quality of transfer paper for attractive printing. HOW TO SEAL A PENDANT COLORED WITH MELTED CRAYON SHAVINGS Jewellery is that part of beautification which includes various forms of designs and gems embedded with it. This has various forms ranging from the most expensive one to the most simple but beautiful ones. A ring looks incomplete without a gem; similarly a necklace seems incomplete without a pendant. Pendant is that part of the necklace which gives it a meaning and an extra bit of enhancement to the necklace. Pendant can exist in various forms, but the most discussed one lately is the one with melted crayon shavings. The reason for this can be known shortly. A pendant is that part of a necklace that is always hanging from it and gives it an identity. It can exist in various shapes, the most preferred of which is the heart shape. A pendant can be made of gold, silver, titanium etc., but the most simple and home made pendant is the one with melted crayon shavings. The process of giving a final polish or impact to the pendant is called as sealing. Sealing means the same as a piece of stamped wax which ensures strength for the material on which it is applied. Crayons are most popularly used for coloring, but they have a disadvantage of their disposal, because once the sharp point is gone, it is of no further use unless someone sharpens it. These crayons can then be converted into shavings and melted together to give it a different shape and color and used for various purposes. The following are the steps for sealing a pendant colored with melted crayon shavings Take the crayons available and cut them in the form of shavings in the way a tree is cut slice by slice. Make the slices as finer as possible to melt them quickly. After the shavings are ready, melt them by placing them on a tough paper and either placing them in an oven or doing it by an iron. The melted shavings are now ready for applying on the pendant to be sealed. Apply the crayon shavings onto the pendant. Make the colored pendant cool by keeping it at normal temperature. Use a metal rod or a log of wood and seal the pendant with a wax coating so that it gets a shiny look onto it. The pendant is now sealed and can be put into a necklace for use. The precaution to be taken here is while melting and sealing. It is suggested that these tasks are done by an adult and done carefully to avoid injuries. The above method of pendant making gives the pendant a simple look but a durable one. Also, it is a best from waste effort as the crayons suggested for use are the broken or spoilt ones. This task has given a great idea of recycling and recreation for generations to learn. The act of making such melted crayon shavings and using them for sealing a pendant will soon become a profession in the near future. HOW CAN I MAKE A BRACELET OUT OF DMC FLOSS Decoration is an activity which everyone loves to do, then it does not matter whether it is a house or an office or any other thing. The simplest way of decoration that humans use to look different and enhance their outer beauty is jewellery. Though women have more jewellery to look rich and beautiful, men dont have that much stuff in number. But both share some common jewellery types which include chains, rings and bracelets. Bracelets can be made from various materials. It is unbelievable that a bracelet does not compulsorily need metals for its creation. It can be made even with rubber or fiber or floss. Thus, to make a bracelet from DMC floss is what interests many for its discussion. Floss in generic form refers to an embroidery thread which is a rough silk obtained from a silkworms cocoon. DMC is a manufacturing unit which manufactures and supplies various kinds of floss to different locations. Thus, to make a bracelet from such a DMC floss is not very tough if proper precautions are taken. The process can be explained as a sequence of steps which are as follows. Bracelets generally are of the wrist size and the thickness can be defined by the amount of floss to be used. So cut 18 25 inches of DMC floss and make the ends line up evenly. Hold the ends together and tie a knot which has a 1 inch tail. Separate the 3 strands and form the number 4 over the adjacent strand. Then just follow the motion used while stitching clothes and make circular rounds about it. Continue this motion till the bracelet attains the desired size. Also the length can be increased as needed. The steps mentioned above give a brief idea about the creation of the bracelet. Many users will have other ideas of the material used for more decoration like beads or pearls and hence, they can go ahead with their own creations. The only care that is to be taken while designing this bracelet is the precision and the sensitivity factor. This is because, you cannot make a bracelet in a hurry, as it can lead to loosening of the floss and will reduce its life. The bracelet also needs to be tight enough to stay tight on the wrist and not fall off. The act of making the bracelet can be done quickly only by a professional. Beginners will take approximately 1 hour to complete this task, and they need to have patience for this. DMC floss is a tough thread and will not easily break off. A blade or a scissor is needed to cut it off and hence it is strong enough to last for a longer duration as compared to other threads. A bracelet is a symbol of friendship as bands are used on friendships day. The best idea is to make a bracelet out of such floss and present it to your friend or your loved one as a symbol of love and gratefulness.

Bipolar Disorder Essay -- Health, Diseases

Mental illness comes in many forms one of the most prevalent forms facing people today is depression. The realm of depression encompasses many different types and forms, some of these are, Seasonal Affect Disorder commonly called SAD, Bipolar Disorder, Postpartum, Chronic Depression, and situational depression to name a few. When many people think about depression they think about a person who is stereotypically down on life. However they don’t see the people who suffer from extreme highs, as well as extreme lows. They don’t see the people who at one point in time can feel really optimistic, and have grad plans. They may be impulsive and make risky choices without thinking about their consequences. The next day they could have problems sleeping, thoughts of suicide, and be very irritable in nature (Segal, 2). These different symptoms are possible signs of bipolar disorder. This papers goal is to explore these highs and lows, the types of bipolar, as well as types of pe ople who are prone to this disease, the types of common behaviors found in people with bipolar, and the kinds of treatment that can be taken. Most people are in there late adolescent to early adult years when they have their first encounter with a bipolar disorder episode. Another prevalent characteristic for those who are diagnosed with bipolar disorder is a genetic link; many people who develop bipolar disorder have an immediate family member with the disease. Many people who develop symptoms of bipolar are misdiagnosed initially due to the confusing onset of symptoms (Segal, 2). Another group of people who strangely enough have a predisposition to bipolar disorder are Americans; Americans bipolar disorder rate is at 4.4%.; whereas, the worldwide rate is at 2.4%... ...nding their lives. I believe that they thought at that point they were only hurting their families by their depressive actions, they probably thought by ending their lives they were making it better for their families. I sincerely hope that one day we will find a way to end the cycle of depression so that no one has to go through the pain that many people all over the world have had to go through when someone decides to end their life. One time in my family was enough two times was two times too many. The best thing you can do as a family member of someone of bipolar is be familiar about the disorder the more you know the more you can do to help should the need arise. One should also familiarize themselves with the warning signs of a possible suicide. I have given a brief introduction to bipolar as a medical condition but there is so much more to know and learn.

The Functions of Stereotypes in Propaganda Essay -- Media Stereotypes

The Functions of Stereotypes in Propaganda "A leader with no followers is a guy taking a walk". Good leaders whether it be opinion or political, rarely if ever walk by themselves. The information theydisseminate more often than not leaves them with a hoard of followers that conform to their ideas or cause. The circulated information is known as propaganda. The Webster dictionary defines propaganda as, "ideas, facts, or allegations spread deliberately to further ones cause or to damage an opposing cause". Propaganda has been around for a long time; the earliest use of the word was in connection with religious missionary activity in the 16th century (Hardwood). Contemporary propaganda for the most part is information or disinformation, spread by leaders through their mouth pieces such as spokespeople or public relations firms. Contemporary propaganda is frequently created with stereotypes that can be easily understood, in order to reach the greatest number of people.
