Reservation System Essay Example for Free

Reservation System EssayI. IntroductionA hotel is an establishment that provides paid lodging on a short-term basis. The provision of basic accommodation, in times past, consisting only of a room with a bed, a cupboard, a small confuse and a washstand has largely been replaced by rooms with modern facilities, including en-suite bathrooms and air conditioning or climate control. The cost and quality of hotels are usually declaratory of the range and type of services available. As one of the fastest growing sectors of the economy of our time, the hotel industry alone is a multi-billion pesos and growing enterprise. It is exciting, never boring and allege unlimited opportunities. The hotel industry is diverse enough for people to work in different areas of interest and still be employed within the hotel industry. notwithstanding the dark things, small hotels still using a manual(a) qualification system and they dont have a system that tail assembly minimize their jobs ma nage a automated database system. Even the government staff habitations like NEDA staff house have the budget solely still using a manual system like log books.The main targets of this matter are for the employees of NEDA STAFF HOUSE. This study aim to benefit the subject of our study, it leave minimize their work and can have a earnest for their respective files. This study pass on also serving the counselors to enhance their knowledge in programming such as Microsoft stain application as wholesome as teamwork passim the study. Interaction and individual stimulation have always been linked to the technological availability of the time and place. With the passing to an information-based society, computers and transactions have evolved from manual transaction. One of the solutions or alternatives to the problems that a hotel is facing, a system was being developed which can edit, delete, filter, monitor and store and secured the records of the customers.The propose system go forth help the staff house to decrease the work of the building administrator because they will be using a less effort like this automated system for their reservation.II. Background of the studyThe NEDA staff house started in 1970 so there employees from far provinces around the Philippines have a stopover in manila in case they have an appointment. Instead of accommodating in an expensive hotel, the staff house can give the same services but has a very low rate of overnight stay. For only P80 per night the staff house has a comfortable rooms and facilities that the NEDA employees can use throughout their stay. By calling the Building Administrator 5 days before they will check in and verify the reservation 2 days before check in, they can have a peaceful overnight stay at the staff house. NEDA staff house accommodating over 13 regions of NEDA giving medication offices all over the Philippines.Before, the staff house has 20 staff from the main office of NEDA. They were resid ing at the staff house to have a temporary office. But nowadays new offices of NEDA established all over the metro manila like their main office at the Pasay city so the NEDA staff house needed only 4 employees (Building administrator, 2 Security Guards, 1 Janitor). As of now the NEDA staff house is still running and accepting accommodations from there different offices aroung the Philippines.III. Statement of the problemGeneral problem. The main problem of this study is the inaccurate reservation of the customers/NEDA Employees.Specific Problems The particularised problems are the following1. Low in security for file storage2. Time monitoring are consuming3. Less data integrity4. encumbrance in hard-hitting and retrieving files5. Possible loss of records and retrieving files6. Difficulty in finding the availability of rooms IV.Objective of the studyGeneral Objective. The study aims to solve the problem encountered and to change the manual reservation system. Using the proponent s reservation system, it will lessen the work of the Building Administrator work. It will be organize to have an automated reservation system.Specific Objective. The specific objectives are as follows1. To increase the security between the management and staff.2. To lessen time consume.3. To highly integrate data.4. To spend less time in searching and retrieving of files.5. To create a back up of files in every successful transaction. 6. To become make easier to find the availability rooms.V. Significance of the studyThis study will show how important is the automated reservation system than a manual system.

American Court System: Design and Functions

American Court System Design and FunctionsIn the United reads, in keeping with our bicameral system of g everyplacenment, we have a treble tourist court system consisting of State and Federal courts. While each system is self-contained it is possible, though infrequent, for questions of State law to finish at the United States domineering Court.The systems and functions of the distinguish and federal courts roughly mirror each other. The pass on courts system serves both trial and appellate functions and in turn, the federal court system serves these purposes at the federal level.The Federal Courts may be divided into expression terce courts, and non-Article III courts. Article III courts were established by/under Article III of the United States Constitution. The Court of International Trade, zone Courts (94 in 50 states, the order of Columbia and Puerto Rico), Courts of Appeals (12 geographic-based and another for the Federal Circuit), and the U.S. commanding Court are a ll Article III courts. Non-Article III courts include Bankruptcy Courts, Tax Court, decisions by U.S. Magistrate Judges and Administrative Law judges (ALS) in various federal agencies.United States District Courts are trial courts of original jurisdiction for federal cases with mandatory appellant jurisdiction over rulings by non-Article III courts. They adjudicate all federal crimes as well as some civil law cases. All federal felony cases are the responsibility of U.S. Magistrate judges.State Courts vary considerably from state to state. In a broad sense, they all follow the pattern, in ascending order, of state minor trial courts, state major trial courts, state intermediate appellate courts, state high courts of last resort (also known as state supreme courts), and the United States Supreme Court.State minor trial courts include municipal courts, rightness of the Peace courts and Magisterial District Courts. These courts serve as original jurisdiction courts for misdemeanor cas es, both civil and fell traffic violations and small civil claims.State major trial courts, which may also be known as Superior Courts, Courts of common pleas and District courts, are trial courts of general jurisdiction. They are much arranged by county or groups of counties, to assay felonies and some civil cases. They sometimes have jurisdiction over minor trial courts.State Intermediate appellant Courts are used in forty out of fifty states. They have mandatory jurisdiction over rulings by the states major trial courts. It is rare for criminal appellants to encourage on appeal here.State high courts of last resort have both mandatory and discretionary jurisdiction over decisions by bring low state courts. This court is a major policy maker for the state due to its position as the final decider on matters of state law.The United States Supreme Court (the High Court of Last Resort in the United States) is arguably the most powerful court in the world. It has absolute control over the cases it hears via its discretionary appellate jurisdiction over decisions made by the U.S. Courts of Appeals. It has jurisdiction over the highest state courts when a question of federal law, to include federal thorough law, is at issue. Typically, less than a third of the cases heard by the countrys highest court are criminal cases.There are eight courts in the state of aluminium and three Federal districts. aluminium Court of the Judiciary oversees judicial officers and is assembled to hear complaints of the Judicial Inquiry Commission. Alabama Probate Courts deal with matters of probate and the governance of estates. Municipal courts in Alabama handle violations of city ordinances. District courts may be either criminal or civil. District civil courts handle small claims suits. District criminal courts handle state law violations, felonies, and misdemeanors. They can also accept a guilty plea in felony cases. Alabama Circuit Courts are state trial courts of general j urisdiction and have jurisdiction to hear civil and criminal cases. The Alabama Court of Criminal appeals presides over appeals in criminal cases. accomplished appeals are the domain of the Alabama Court of Civil appeals. At the top of the hierarchy is the Alabama Supreme Court, the states court of last resort. District courts in Alabama are in the 11th Circuit. They trial courts of original jurisdiction over federal cases.A criminal case that goes to trial may end up using trial, appellant and supreme courts. This basic structure and sequence is the comparable in both state and federal courts. Trial courts of general jurisdiction hear felonies and non-small claims civil cases. They may also have appellate jurisdiction over a states minor trial courts. A case may end at this level if the defendant is convicted and does not appeal, or if he is found innocent. appellant courts have jurisdiction over decisions made by the major trial courts. Appellate courts do not rule on guilt or i nnocence but rather on whether the trial was conducted properly. It is rare for a defendant to win at the appellate level. If the decision of the appellate court is challenged the case will proceed to the State Supreme court, also known as the State court of last resort. Typically, the State Supreme Court hears only a few criminal cases annually. In order to move ahead to the United States Supreme Court, a case must include a question of federal law or federal constitutional law.All states do not have the same court design. Part of the purpose of a dual court system is to allow states the freedom to govern themselves and to be separate and independent of the federal government. This cosmos the case, each state has developed its own court system and terminologies that serve the people of that state. While the overall structures of the court of one state may be similar to another/others, the fact that each state has its own unique laws guarantees variations in their court systems.

Madonna and Child Paintings Throughout History

bloody shame and tyke Paintings Throughout HistoryThrough history, people had used guile as a reflection of their religious beliefs and culture values. The illustration of bloody shame and Child had been one of the most recurring fine arts in Christianity and European art in general. According to Christian beliefs, Madonna represents the virgin marry and the child represents baby Jesus. Thought these religious flicks and sculptures of The Madonna and Child may be along the same lines in their depiction of Christian iconography and artistic zeal, each carries a different taste and reflects the different time periods and the different artists that had created them. Three examples of these paintings are Madonna and Child, created by Berlinghiero from the Italian Maniera Greca period, Madonna and Child created by Duccio during the Italian Proto-Renaissance, and Madonna and Child with Angels created Cosimo Rosselli during the Early Italian Renaissance periods. When a viewer observe t hese triple Italian paintings, the viewer would recognize a development that takes place through the three time periods which is from the early thirteenth century to tardilyr fifteenth century. Differences in these three paintings include the illustrations of the figures, drapery style, treatment of stead, and inclusion or the exclusion of the viewer. Nonetheless, the paintings represent similar religious and cultural values since they all depict the Christian iconography of the Virgin Marry with baby Jesus. Madonna and Child is a very common Christian iconography that was witnessn through history since the tangled Empire.The painting Madonna and Child was painted around 1230 during the Italian Maniera Greca period by Berlinghiero, the outstanding painter of the thirteenth-century Lucca (Museum Label). This painting is tempera on wood with the two figures on front of a golden background. Madonna is wearing a huge dark blue cloak with well-fixed decorations which covers most o f her body and a reddish dress underneath the cloak that can only be seen in her arms. To depict her modesty the only things that can be seen from her body are her face, neck, and hands. Her face shows a cast down skin senses with the lines around her eyes and her small mouth that depicts a frown. Her hand has an unrealistic look which are elongated and skinny. According to the Museum label, Berlinghiero was always open to involved influence, and this Madonna is of the Byzantine type known as the Hodegefria, in which the Madonna points to the child as the way to salvation. The Hodegefria illustrate the Christian values and the value of the Byzantine art. The Child is wearing an orange Clock that covers most of his body. He is seated on top of one of his mothers hands with his body tilted towards his mother and his lintel facing the viewer. One of his hand points towards the right and in the other hand he is prop a scroll that represent the religious scriptures, which carries a Christian iconography in which the scriptures represents the bible. Thought his is suppose to be a child his face is an adult like face, which excessively can be a religious iconography that show Jesus as a mature child who leads people to salvation.Berlinghieros Madonna and Child is in organic fertilizer and unrealistic when it comes to the drapery of the textileing and the treatment of space. The figures are also set in an awkward way with inorganic style of the body. There are many folds in the figures clothes which extreme for a realist dress. The treatment of space is missing in this painting, where the figures seem to be flat and the light source is not clear in depicting the space and atmosphere. This painting is similar in its drapery and treatment of space to the painting Madonna and Child Enthroned with Angels which is from the same time period. Thought the painting is unrealistic, it is still considered as a very commodious artistic work that depicts cultural and relig ious values of that time.Duccios Madonna and Child was created during the Italian Proto-Renaissance around 1300. Like the Berlinghieros painting, Duccios painting is tempera on wood with golden background. Moreover, Madonna is wearing a blue cloak with golden lines on the edges which covers most of her body. Madonna is looking at the Child who is trying to play with her checks and retentivity him with both of her hands. She seems to have a sad look with her tilted head towards her child. The Child or Jesus is also wearing an orange dress with a red cloak over his shoulders. Compare to the child from Berlinghieros painting, Duccios child is looks more like a normal child. We can see that the depiction of the child has real to a more realistic and organic one. In this painting not only does the child looks realistic in his facial characteristics but with his childish endeavour while playing with his mother checks. The drapery style is more organic than that of Berlinghiero but is n ot totally realistic. It has a very heavy and earthy palpateing with its huge curves and wrinkles. This painting also lacks the emphases of space, since the figures looks like flat on the golden background. This painting can be compared with Giottos paining Madonna Enthroned with Angels and Saints, which is from the same time period, where we can see similar drapery style and facial characteristics of the child. Furthermore, this painting also shows the counting religious values of Italian art. This painting, like all the Madonna and Child paintings, has the Christian values.The third painting is the Early Italian Renaissance painting Madonna and Child with Angels by Cosimo Rosselli which dates about 1480 to 1482. Thought this painting is made of tempera and gold on wood, it is much more complex than both of the other paintings. In this painting Madonna is dressed in a light red cloth and a light blue cloak floating over her head and shoulders while the child is shown nude, which i s different than that of Berlingiero and Duccios paintings. The posture of the figures is also different Madonna is holding the child with both of her hands to make him stand on top of a table. Although, the childs body is a little disproportional, the bodies of both figures are more organic and natural. The bodies do not have a longitude hands and awkward faces like the other two paintings, which show the development in artistic design of the figures. Moreover, Rossellis painting has a more developed drapery style and space treatment. The drapery is more organic with ordinary looking wrinkles. The treatment of space is also a lot more developed than the other two paintings. Since the other two paintings had the figures as if they are flat, this painting is more organic because the viewer can feel like the figures are close while the background is seems far. This painting also has a vanishing point that gives the painting the feeling of space.As seen in the three paintings of the Ma donna and Child, we can see that art develops through the years. Even thought the paintings of Madonna and Child carries the same religious cultural values, one can see how the style of the painting changes over periods of time in its drapery style, space treatment, figures characteristics, and even the postures of the figures. As a result, we saw that the depiction of the Madonna and Child in the late fifteenth century is more complex and organic than that of the early thirteenth century.

Mechanically agitated fermenters

roboticly agitate fermentersAbstractTraditional mechanistic excitation fermenters fuck off dominated the industry since the antibiotic era as invites changed new fermenter designs were created. As a result air lift provoke fermenters were created and have galore(postnominal) merits in comparison to mechanical agitation fermenters. In this essay we will go through both systems merits in regards to mixing, aeration, unimaginativeity and energy costs first appearanceAgitators atomic number 18 mechanical instruments utilizationd to mix substances, Fermentation is an age old art in which organic substances argon broken down and reassembled into other substances. Fermenters are large bioreactors in which fermentation occurs, fermenters are the instruments employed to manufacture economically viable biological products. Their basic function is to provide a controlled environment in order to achieve optimal harvest-feast and product formation of the particular biological produc t required. For biotech and pharmaceutical purposes the products from fermentation are microbic cells or biomass, enzymes, and microbial metabolites such as antibiotics and ethanol. The basic desired functional properties of all Fermenters are that they groundwork create gas fluent interfaces without making foam a bother. They should sufficiently hold up dispersed phases and al dispirited reasonable hotness transfer of training. They should also be able to control bulk f low gear so no numb(p) zones can form. In league with these functional requirements they should be cheap, robust and have a simple mechanical design additionally they should have low military group consumption and be easy to scale up. In this essay we will compare two different types of Fermenters, airlift Fermenters and mechanically agitated Fermenters.Both types of mixers indoors Fermenters results in the intermingling of two or more dissimilar portions of material resulting in the acquirement of either phy sical or chemical uniformity in the last(a) product. In industrial fermentation reactions there is a basic requirement of substrate, organism, water and oxygen. Mixing within Fermenters usually defecates equilibrium between, rate, purity and return yield. automatonlike agitators are used in traditional Fermenters for mixing they maintain optimum substrate biomass concentration everywhere, keeps solid suspended, disperse oxygen, and allow an upkeep of total smatter surface area and the recycling of air bubbles (figure 1).Mechanically agitated FermentersMechanically agitated Fermenters require a relatively high input of energy per building block volume. In these systems a large variety of impeller shapes and sizes are available to produce different flow patterns inwardly the Fermenter. The use of multiple impellers produces better mixing that kit and boodle in addition with baffles that are normally used to reduce vortexing. Approximately 70-80% of the volume of stirred react ors is filled with liquid. Foaming may be a problem with this type of Fermenter. Foam breakers, may be necessary. It is better to use mechanical anti foamers over chemical anti foamers because the chemicals often reduce oxygen transfer rate. One of the limits of this system is the use of high speed impellers can damage and even destroy cells. Aspect ratios of these Fermenters vary over a wide range. For aeration to be increased a higher facial gesture ratio is needed (H/D rates). Increased aeration results in greater contact times between liquid and climb bubbles and produces hydrostatic pressure at the bottom of the Fermenter.Bubble column /Air Lift FermentersIn these systems aeration and mixing are achieved by gas sparging. Gas is sparged wholly into the riser. Decreased liquid fluid density and gas accumulation cause the liquid in the riser to mover upwards. Gas disengages at the top of the vas leaving heavier bubble-free liquid to recirculate through the downcomer. This proc ess needs less(prenominal) energy than mechanical stirring. This mixing, method is used in the production of beer and bakers yeast. The advantages of this method over mechanical agitation are, lack of moving separate, low capital costs satisfactory mass and waken transfer. Air lifted Fermenters produce heterogeneous and homogenous culture medium flows. In heterogeneous flow, Bubbles and liquids tend to rise up in the center of the column while a corresponding down flow of liquid occurs pricey the walls. In Homogenous flow, bubbles rise with the same upward velocity with no back-mixing of the gas phase. Foaming may also be a problem with these Fermenters. on that point are two kinds of air lift Fermenters internal loop and external loop Fermenters. Mixing is better in external loop Fermenters because the riser and downcomers are further apart in external loop vessels which cause the density difference between fluids in the downcomer and riser to be greater meaning circulation of the liquid vessel is faster overdue to fewer bubbles being carried to the downcomer. Airlift Fermenter are normally used for the culture of immobilized catalyst and the culture of plant and animal cells because of their low sheer level.MixingStirred Fermenters and air lifted Fermenters both offer adequate mixing and mass transfer. However when a large Fermenter is required (50-500M3) for a low viscosity medium air lift vessels may be a better choice due to their advantages. These being they are cheap to pitch and operate. When scale up is required large mechanical agitators are impractical as the function required to achieve adequate mixing becomes very high. Mechanical agitators are used for high viscosity cultures. Mass transfer rates decline at viscosities greater than 50-100 cP. Mechanical agitation creates much more heat than sparging of compressed gas. This can become a problem when the reaction temperature is high for example when trying to produce single celled proteins f rom methanol, removal of frictional stirrer heat can be problematic this is where air-lift agitation is preferred.ComparisonIn brief the conventional, stirred tank bioreactor has dominated the industry since its successful coating in the antibiotic era and most fermentation processes today use Fermenters of this type because of this. However due to change in the industry in regards to products in demand. Such as the growth of hydrodomas cell and recombinant DNA technologies of genetically modified cells of plant, microbial and mammalian origin imposed new demands that traditional agitators could not provide at an economically viable level. For this reason new novel Fermenters where designed and put into use. The air lift Fermenter being one of them. The air lift Fermenter has no movable parts or motors the only power requirement comes from the air compressors that provide air through the sparging system. No mechanical agitation occurs, the air bubbles forced through the sparger cau se induced turbulent liquid mixing and mass transfer in which mixing rates and aeration rates are coupled together. Their main advantage is low sheer and energy requirement along with aseptic seals not being required around the shaft which makes them highly suitable for producing single celled protein. Additionally in air lift Fermenters mixing is improved by the inclusion of a draught tube to impart a circulation loop which produces a higher oxygen mass coefficient (KLA). The Air lift Fermenters are ideal when there is need for gentle agitation. Whereas the conventional mechanical agitated Fermenters have a broader range of application but they have a poorly defined mixing pattern in comparison to airlift Fermenters. Additionally they cannot be aerated at a high enough rate due to impeller flooding. Practicality wise they have a long life, the mechanical agitation configuration has become too established in processes for new methodologies to replace them. It would be too expensive to do.AerationTo provide aeration into a vessel means to supply or expose the medium to the circulation of air. Airlifted Fermenters provide a much greater aeration than mechanical agitators as gas is constantly pumped into the medium and consequently causes fluid circulation. Aeration within a mechanically agitated Fermenter is controlled by the type of impeller and baffle system. For example Turbines, propellers and paddles are generally used in low viscosity systems and operate at high rotational speed inside the Fermenter. Turbines are normally used for dispersion of gases in liquids. There are many types angled-blade turbines and retreating-blade turbines, the rushton/inclined six blade impeller. Similarly for large vessels with high aspect ratios it is common practice to mount more than one impeller of the same shaft. Baffles are of particular importance as they prevent gross vortexing which is detrimental to mixing/ aeration they are normally fitted on the walls of a vessel.P racticalityDepending on the product being produced in the Fermenter and the viscosity of the medium practicality of mechanical and airlift agitators differ. Mechanical agitators are very practical when it comes to mixing highly viscous non newtonian mediums however the power for this can be very high and subsequently this increases the costs. Additionally the practicality of the Fermenter being used in regards to merits is determined by the type of product being produced, the microbiology of particular cell systems in use coupled with the morphology and nutritional requirements needed for optimal growth. The geometric configuration of the Fermenter play an important role. Effective mixing to minimise temperature, PH concentration gradient are very important particularly with mechanically agitated Fermenters especially when a process is scaled up. Additionally the viscosity of the medium plays an important role, does the medium behave in a Newton or non Newton manner is it a solid or liquid state fermentation. The sheering effect of a particular agitation system dictates whether sheer sensitive cells can be cultivated.All of this is taken into account keeping in mind what is best for economic performance. For example large mechanical agitators have better Practical use than air lift agitators for use with the following cell systems, these are immobilised Bacteria, yeast and plant cells and are used for the for the production of products such as ethanol, monoclonal antibodies, growth factors and medicinal products. This is because they can tolerate sheer at a level best for productivity. Resulting in large quantities of moderate quality products with good profit costs. cooknatively air lift agitators are generally used for the cell systems of bacteria yeast and other fungi producing products such as single celled proteins E.G. Quorn, enzymes, secondary metabolites and biosurfactants. This is because they are more economically practical due to them having low sheer values meaning they do not damage the cells, they have much get rails costs and they can produce higher value sheer sensitive GM products. Furthermore when it comes to scale up with airlifted Fermenters it can be difficult to alter stirring rates making it difficult to deal with important rheological changes and foaming. This is where mechanically agitated Fermenters are favoured. Also air lifted Fermenters are less flexible than mechanically agitated systems as Aeration is responsible for homogenization.Energy use and CostMechanical agitators use more energy have moving parts, seals and are more expensive to run than airlift fermenters.The main benefit of air-lift Fermenters over mechanical agitators is that they can be constructed at much greater reactor volumes air-lift Fermenters can be built at volumes of several thousands cubic meters while mechanical operated agitators can be scaled up to a maximum of 800-1500 m3 (Ruitenberg et al 2001) As a consequence of this the i nvestment costs of air-lift Fermenters is significantly set about when compared to mechanically operated agitators of the same capacity. At higher volumes mechanical agitators cause mechanical problems because of the large power requirements of the impeller. Furthermore, scale-up of air-lift Fermenters is much more straight forward than that of mechanical agitated fermenters. Scale-up from a 5 m3 pilot to 1500 m3 and larger is well defined. (Ruitenberg et al 2001) Figure 3 shows the upper-case letter cost comparison of air-lift Fermenters vs. mechanical agitated fermenters. The cost for a mechanically agitated fermenter is defined as 1 for a 1500 m3 tank. The cost of a 1500 m3 air-lift fermenter is a bit lower than that of the equivalent mechanically agitated fermenter. However, the investment cost follows the 0.6 rule until 6000 m3 is reached. Above 6000 m3, more than one air lift fermenter may need to be used.Another advantage of air-lift fementers over mechanical agitated ferme nters is that the oxygen input efficiency is the same or better at considerably lower shear. Additionally Because no moving parts are present in air-lift Fermenters, the costs for maintenance will be lower as compared to mechanically agitated fermenters. The combination of high oxygen input efficiencies and low maintenance costs results in lower operational costs.Shear rates are much lower in air-lift Fermenters than in mechanically agitated fermenters. Low shear rates facilitate growth of biofilms, which can increase the reaction rate. This advantage is thought to be greatest when thermophilic bacteria are used. Because a three-phase settler can be integrated on top of an air-lift fermenter, the solids retention time can be separated from the hydraulic retention time causing biomass retention, (Ruitenberg et al 2001)ConclusionMechanically agitated Fermenters have been in use since the beginning of the industry however due to changes in demand that comes with time in regards to tec hnology and products needed novel Fermenter ideals were designed and put into fruition the air lift Fermenter is but one. In many ways this air lift agitators have many advantages as was just discussed.ReferencesBarker, T. W. and J. T. Worgan (1981).
