CHAPTER 1 INTRODUCTION Diabetes Mellitus is a progressive metabolic disorder which influences a growing number of people—the worldwide elevation in numbers of adults with diabetes has been predicted at 122%, from 135 million in 1995 to 300 million in 2025 (Feinglos and Bethel, 2008). In addition, it is a common, costly medical condition often related with significant morbidity and mortality (Schilling McCann, 2007). There are several types of diabetes mellitus and these include: Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus, Juvenile Diabetes Mellitus and Diabetes Me llitus brought about by pregnancy. This paper will only focus specifically on Type 2 Diabetes Mellitus. Type 2 Diabetes Mellitus is a worldwide health crisis as stressed by Feinglos and Bethel (2008); it is previously termed as non-insulin dependent diabetes mellitus or NIDDM (Schilling McCann, 2007). It is also labelled as adult-onset diabetes for the reason that is typically or frequently linked with older age, commonly after age 40; in this medical condition, insulin resistance with varying degrees of insulin secretory defects is evident (Schilling McCann, 2007). Diabetes Mellitus in general can be affected by a variety of factors which may or may not be modifiable. The factors that cannot be altered include age, family history and genetics (Schilling McCann, 2007). On the contrary, the...

Minor capacity judgement Essay Mohori Bibee and another Vs. Dharmodas Ghose Mohori Bibee and another Vs. Dharmodas Ghose Options Dock Print PDF Court :  Kolkata Reported in :  (1903)30IndianAppeals114 Judge :  Lord Macnaghten; Lord Davey; Lord Lindley; Sir Ford North; Sir Andrew Scoble; Sir Andrew Wilson, JJ. Decided On :  Mar-04-1903 Acts :  Indian Evidence Act, 1877 Section 115; Indian Contract Act Sections 41, 19, 64, 65 Appellant :  Mohori Bibee and another Respondent :  Dharmodas Ghose Advocate for Respondent :  W. W. Box, Adv. Advocate for Appellant :  Watkins; Lempriere, Advs. Judgment: SIR FORD NORTH, J. On July 20, 1895, the respondent, Dhurmodas Ghose, executed a mortgage in favour of Brahmo Dutt, a money-lender carrying on business at Calcutta and elsewhere, to secure the repayment of Rs. 20,000 at 12 per cent. interest on some houses belonging to the respondent. The amount actually advanced is in dispute. At that time the respondent was an infant; and he did not attain twenty-one until the month of September following. Throughout the transaction Brahmo Dutt was absent from Calcutta, and the whole business was carried through for him by his attorney, Kedar Nath Mitter, the money being found by Dedraj, the local manager of Brahmo Dutt. While considering the proposed advance, Kedar Nath received information that the respondent was still a minor; and on July 15, 1895, the following letter was written and sent to him by Bhupendra Nath Bose, an attorney:— â€Å"Dear Sir,—I am instructed by S. M. Jogendranundinee Dasi, the mother and guardian appointed by the High Court under its letters patent of the person and property of Babu Dhurmodas Ghose, that a mortgage of the properties of the said Babu Dhurmodas Ghose is being prepared from your office. I am instructed to give you notice, which I hereby do, that the said Babu Dhurmodas Ghose is still an infant under the age of twenty-one, and any one lending money to him will do so at his own risk and peril. † Kedar Nath positively denied the receipt of any such letter; but the Court of first instance and the Appellate Court both held that he did personally receive it on July 15; and the evidence is conclusive upon the point. On the day on which the mortgage was executed, Kedar Nath got the infant to sign a long declaration, which, he had prepared for him, containing a statement that he came of age on June 17; and that Babu Dedraj and Brahmo Dutt, relying on his assurance that he had attained his majority, had agreed to advance to him Rs. 0,000. There is conflicting evidence as to the time when and circumstances under which that declaration was obtained; but it is unnecessary to go into this, as both Courts below have held that Kedar Nath did not act upon, and was not misled by, that statement, and was fully aware at the time the mortgage was executed of the minority of the respondent. It may be added here that Kedar Nath was the attorney and agent of Brahmo Dutt, and says in his evidence that he got the declaration for the greater security of his â€Å"client. † The infant had not any separate legal adviser. On September 10, 1895, the infant, by his mother and guardian as next friend, commenced this action against Brahmo Dutt, stating that he was under age when he executed the mortgage, and praying for a declaration that it was void and inoperative, and should be delivered up to be cancelled. The defendant, Brahmo Dutt, put in a defence that the plaintiff was of full age when he executed the mortgage; that neither he nor Kedar Nath had any notice that the plaintiff was then an infant; that, even if he was a minor, the declaration as to his age was fraudulently made to deceive the defendant, and disentitled the plaintiff to any relief; and that in any case the Court should not grant the plaintiff any relief without making him repay the moneys advanced. By a further statement the defendant alleged that the plaintiff had ubsequently ratified the mortgage; but this case wholly failed, and is not the subject of appeal. Jenkins J. , who presided in the Court of first instance, found the facts as above stated, and granted the relief asked. And the Appellate Court dismissed the appeal from him. Subsequently to the institution of the present appeal Brahmo Dutt died, and this appeal has been prosecuted by his executors. The first of the appellants reasons in support of the present appeal is that the Courts below were wrong in holding that the knowledge of Kedar Nath must be imputed to the defendant. In their Lordships opinion they were obviously right. The defendant was absent from Calcutta, and personally did not take any part in the transaction. It was entirely in charge of Kedar Nath, whose full authority to act as he did is not disputed. He stood in the place of the defendant for the purposes of this mortgage; and his acts and knowledge were the acts and knowledge of his principal. It was contended that Dedraj, the defendants gomastha, was the real representative in Calcutta of the defendant, and that he had no knowledge of the plaintiffs minority. But there is nothing in this. He no doubt made the advance out of the defendants funds. But he says in his evidence that â€Å"Kedar Babu was acting on behalf of my master from the beginning in this matter†; and a little further on he adds that before the registration of the mortgage he did not communicate with his master on the subject of the minority. But he did know that there was a question raised as to the plaintiffs age; and he says, â€Å"I left all matters regarding the minority in the hands of Kedar Babu. † The appellants counsel contended that the plaintiff is estopped by s. 115 of the Indian Evidence Act (I. f 1872) from setting up that he was an infant when he executed the mortgage. The section is as follows: â€Å"Estoppel. When one person has by his declaration act or omission intentionally caused or permitted another person to believe a thing to be true, and to act upon such belief, neither he nor his representative shall be allowed in any suit or proceeding between himself and such person or his representative to deny the truth of that thing. † The Courts below seem to have decided that this section does not apply to infants; but their Lordships do not think it necessary to deal with that question now. They consider it clear that the section does not apply to a case like the present, where the statement relied upon is made to a person who knows the real facts and is not misled by the untrue statement. There can be no estoppel where the truth of the matter is known to both parties, and their Lordships hold, in accordance with English authorities, that a false representation, made to a person who knows it to be false, is not such a fraud as to take away the privilege of infancy: Nelson v. Stocker. 0 The same principle is recognised in the explanation to s. 19 of the Indian Contract Act, in which it is said that a fraud or misrepresentation which did not cause the consent to a contract of the party on whom such fraud was practised, or to whom such misrepresentation was made, does not render a contract voidable. The point most pressed, however, on behalf of the appellants was that the Courts ought not to have decreed in the respondents favour without ordering him to repay to the appell ants the sum of Rs. 0,500, said to have been paid to him as part of the consideration for the mortgage. And in support of this contention s. 64 of the Contract Act (IX. of 1872) was relied on:— â€Å"Sect. 64. When a person at whose option a contract is voidable rescinds it, the other party thereto need not perform any promise therein contained of which he is promisor. The party rescinding a voidable contract shall, if he have received any benefit thereunder from another party to such contract, restore such benefit, so far as may be, to the person from whom it was received.    Both Courts below held that they were bound by authority to treat the contracts of infants as voidable only, and not void; but that this section only refers to contracts made by persons competent to contract, and therefore not to infants. The general current of decision in India certainly is that ever since the passing of the Indian Contract Act (IX, of 1872) the contracts of infants are voidable onl y. This conclusion, however, has not been arrived at without vigorous protests by various judges from time to time; nor indeed without decisions to the contrary effect. Under these circumstances, their Lordships consider themselves at liberty to act on their own view of the law as declared by the Contract Act, and they have thought it right to have the case reargued before them upon this point. They do not consider it necessary to examine in detail the numerous decisions above referred to, as in their opinion the whole question turns upon what is the true construction of the Contract Act itself. It is necessary, therefore, to consider carefully the terms of that Act; but before doing so it may be convenient to refer to the Transfer of Property Act (IV of 1882), s. of which provides that every person competent to contract and entitled to transferable property. . . . is competent to transfer such property. . . . in the circumstances, to the extent, and in the manner allowed and prescribed by any law for the time bring in force. That is the Act under which the present mortgage was made, and it is merely dealing with persons competent to contract; and s . 4 of that Act provides that the chapters and sections of that Act which relate to contracts are to be taken as part of the Indian Contract Act, 1872. The present case, therefore, falls within the provisions of the latter Act. Then, to turn to the Contract Act, s. 2 provides: (e) Every promise and every set of promises, forming the consideration for each other, is an agreement. (g) An agreement not enforceable by law is said to be void. (h) An agreement enforceable by law is a contract. (i) An agreement which is enforceable by law at the option of one or more of the parties thereto, but not at the option of the other or others, is a voidable contract. Sect. 0 provides: â€Å"All agreements are contracts if they are made by the free consent of parties competent to contract for a lawful consideration and with a lawful object, and are not hereby expressly declared to be void. † Then s. 11 is most important, as defining who are meant by â€Å"persons competent to contract†; it is as follows; â€Å"Every person is competent to contract who is of the age of majority according to the law to which he is subject, and who is o f sound mind, and is not disqualified from contracting by any law to which he is subject. † Looking at these sections, their Lordships are atisfied that the Act makes it essential that all contracting parties should be â€Å"competent to contract,† and expressly provides that a person who by reason of infancy is incompetent to contract cannot make a contract within the meaning of the Act. This is clearly borne out by later sections in the Act. Sect. 68 provides that, â€Å"If a person incapable of entering into a contract, or any one whom he is legally bound to support, is supplied by another person with necessaries suited to his condition in life, the person who has furnished such supplies is entitled to be reimbursed from the property of such incapable person. It is beyond question that an infant falls within the class of persons here referred to as incapable of entering into a contract; and it is clear from the Act that he is not to be liable even for necessaries, a nd that no demand in respect thereof is enforceable against him by law, though a statutory claim is created against his property. Under ss. 183 and 184 no person under the age of majority can employ or be an agent. Again, under ss. 47 and 248, although a person under majority may be admitted to the benefits of a partnership, he cannot be made personally liable for any of its obligations; although he may on attaining majority accept those obligations if he thinks fit to do so. The question whether a contract is void or voidable presupposes the existence of a contract within the meaning of the Act, and cannot arise in the case of an infant. Their Lordships are, therefore, of opinion that in the present case there is not any such voidable contract as is dealt with in s. 64. A new point was raised here by the appellants counsel, founded on s. 5 of the Contract Act, a section not referred to in the Courts below, or in the cases of the appellants or respondent. It is sufficient to say tha t this section, like s. 64. starts from the basis of there being an agreement or contract between competent parties, and has no application to a case in which there never was, and never could have been, any contract. It was further argued that the preamble of the Act shewed that the Act was only intended to define and amend certain parts of the law relating to contracts, and that contracts by infants were left outside the Act. If this were so, it does not appear how it would help the appellants. But in their Lordships opinion the Act, so far as it goes, is exhaustive and imperative, and does provide in clear language that an infant is not a person competent to bind himself by a contract of this description. Another enactment relied upon as a reason why the mortgage money should be returned is s. 41 of the Specific Relief Act (I. of 1877), which is as follows: â€Å"Sect. 41. On adjudging the cancellation of an instrument the Court may require the party to whom such relief is granted to make any compensation to the other which justice may require. Sect. 38 provides in similar terms for a case of rescission of a contract. These sections, no doubt, do give a discretion to the Court; but the Court of first instance, and subsequently the Appellate Court, in the exercise of such discretion, came to the conclusion that under the circumstances of this case justice did not require them to order the return by the r espondent of money advanced to him with full knowledge of his infancy, and their Lordships see no reason for interfering with the discretion so exercised. It was also contended that one who seeks equity must do equity. But this is the last point over again, and does not require further notice except by referring to a recent decision of the Court of Appeal in Thurstan v. Nottingham Permanent Benefit Building Society21, since affirmed by the House of Lords. 22 In that case a female infant obtained from the society of which she was a member part of the purchase-money of some property she purchased; and the society also agreed to make her advances to complete certain buildings thereon. They made the advances, and took from her a mortgage for the amount. On attaining twenty-one she brought the action to have the mortgage declared void under the Infants Relief Act. The Court held that, as regards the purchase-money paid to the vendor, the society was entitled to stand in his place and had a lien upon the property, but that the mortgage must be declared void, and that the society was not entitled to any repayment of the advances. Dealing with this part of their claim Romer L. J, says23: â€Å"The short answer is that a Court of Equity cannot say that it is equitable to compel a person to pay any moneys in respect of a transaction which as against that person the Legislature has declared to be void. So here. Their Lordships observe that the construction which they have put upon the Contract Act seems to be in accordance with the old Hindu Law as declared in the laws of Menu, ch. viii. 163; and Colebrookes Dig. liii. 2, vol. ii. p. 181; although there are no doubt, decisions of some weight that before the Indian Contract Act an infants contract was voidable only in accordance with English law as it then stood. The appeal, therefore, wholly fails; and their Lordships will humbly advise His Majesty that it should be dismissed. The appellants must pay the costs of the appeal.

Market Research and Marketing Research Essay Example for Free

Market Research and Marketing Research Essay Research is the process of gathering, processing and analyzing information on markets. The scope of such research is limited to the study of markets and does not include studies on the brand or product to be marketed. Market research is a subset of marketing research. Marketing Research is the process of gathering, processing and analyzing information for the purpose of marketing a product. It includes, but is not limited to market research. Marketing research extends to other areas of marketing activity like: 1. 2. 3. 4. 5. Studies on consumer behavior Brand and positioning research Research on product and packaging Research on communication strategies and advertising channels and their effectiveness Studies on sales promotion strategies and effects of discounts and sales promotion strategies on customer buying and consumption habits 6. Brand perception studies 1 Difference between Qualitative vs. Quantitative 2 Importance of Marketing Research The importance of marketing research in management extends to intelligent decision making, maximizing profits, increasing the sales, minimizing the risks and ascertaining whether a new product will be profitable in a given market at a given time. What is Marketing Research? This research can be defined as the process of gathering recording and analyzing the data related to certain products and services. This need for market research is derived from the concept that only by understanding the needs and wants of the target audience and by effectively meeting them, you will be able to achieve the organizational goals and surpass the competition n the specific market. Thus, arises the need to collect data about the customers, competitors, and other forces in the marketplace. This data in turn is collected and analyzed to make relevant marketing decisions, be it in relation to setting up a business, developing a product, creating a brand or coming up with an advertising campaign. What is t he Importance of Marketing Research? To Make Marketing Decisions: This research helps the marketers to make a decision about the product or service. Sometimes a marketer might believe that the new product or service is useful for the customers. However, research may show that customers do not need a product or are meeting their needs with a certain competitor product and so on. Similarly good research strives to provide options for the successful introduction of new products and services. This makes the market entry of a new product or service less risky. Survive the Competition: Marketing research helps in ascertaining and understanding competitor information such as their identity, marketing network, customer focus and scale of operations. This helps in surviving and in certain cases, even leaving behind the competition. Moreover, with market research you can also help understand the under-served consumer segments and consumer needs that have not 3 been met. Helps to Decide Target Markets: Research helps provide customer information in terms of their location, age, buying behavior and gender. This helps the marketers zero in on the target markets and customers for their products and services. Maximize Profits: Apart from profit maximizing steps such as item optimization, customer profitability analysis, and price elasticity, marketing research allows you to find out methods that can help you maximize profits. For example, a products price elasticity research can help you ascertain the impact of an increased price on the sales and the profits of a product. This emphasis on profitability also helps the companys focus to shift from maximizing sales to increasing the profits of a company. This helps the company survive in the long run and maximize its profits. Increasing the Sales: Increasing the sales of your products or services helps a company in maximizing its profits. By understanding the customers needs, wants and attitude towards the products and determining whether your products fit the bill, marketers can increase their sales. This helps in not only increasing the sales to the target customers and people already using the product but also converting the non users into customers for the product. With an understanding of the customer, competitors, products and the overall industry needs, this research can equip the management with the power to make better decisions. However, the importance of marketing research is limited to just being a marketing tool that helps you make an informed decision. So rather than basing all your management decisions on a customer survey, use this tool as a guide and supplement it with intelligent decision making.

Development Of An Automatic Class Scheduler

Development Of An Automatic Class Scheduler Regarding the rapid growth of the number of students and the increasing number of courses offered in school, colleges and institution, the task of scheduling classes to fit into timetables and into existing facilities is becoming much more complicated. At the present time, class scheduling not only needs to fit the courses offered but also has to be performed based on many factors, such as availability and capacity of the room, cost occurred when the rooms are engaged by any courses, losses occurred when the rooms are left out, etc. Class Scheduler is an easy to use single or multi-user application for scheduling students classes. The software is ideal for schools, colleges and other institutions that must create class schedules. Class Scheduler can be used by a single teacher or by a group of students to schedule classes. The idea behind Class Scheduler is to increase the productivity of classroom administrators by automating the class scheduling process by automatically setting up course times and assigning rooms and instructors. We can view course schedule, student schedule, instructor schedule and classroom schedule online. We can also resolve clashes without effort, and preferences of staff and students action with ease and serves a clash-free and error-free timetable. It also saves time and labour. 2. OBJECTIVE OF THE STUDY Timetable creation for has always been an error-prone task, normally resulting in multiple iterations of creation and proof-reading. Changes desired by teaching staff, changes of course locations etc. also require an adaptation of the previously created timetables. Traditional approach to generation of timetable had great difficulties due to large search space which were created as a result of number of variables that need to be considered in such problems. Hence the objective of this project is to automatically generate time tables for the betterment of the teaching staff students. PROBLEM STATEMENT The manual system of preparing Time Table in colleges with large number of students is very time consuming and usually ends up with various class clashes either at same time or with same teacher, having more than one class at a time. These are just due to common human error which are very difficult to prevent in processes as these. To overcome these problem people usually end up making injudicious use of classrooms and labs. To overcome all these problems we propose to make an automated system. INTRODUCTION CLASS SCHEDULER is the online timetable generator for schools, colleges and any other institutions that must create class schedules. CLASS SCHEDULER offers functionality for generating timetables (for students or teachers) as well as overview timetables, i.e. all courses in a certain semester for any given degree. This study is expected to solve those problems and improve the qualitative aspects of generating schedules as follows: Shortening the time in establishing the timetables with computer assistance and better information. Easing the procedure of establishing the timetables Establishing the timetables according to maximize facilities utilization and instructors preferences. Developing an interactive computer link to facilitate data output and the interpretation of the results. DESCRIPTION OF THE SYSTEM The project aims at developing an automated Time Table generator. The system will take various inputs like details of student, subjects, classrooms and teachers available. Depending upon these inputs it will generate a possible Time Table. Making optimal utilization of all the resources such as rooms and labs and distributing classes in a way that will best suit any of constraints or college rules. List of subjects may include elective as well as core subjects. Features: Simple Data Entry: It is quick and easy to enter information of all subjects, years (FE, SE, TE, BE), courses ( computer science, extc, bio-medical), Rooms and teachers. Automatic generation: In few minutes, the program generates a complete timetable that fulfills all your requirements. The program follows all organizational requirements such as selection for number of working days of the week, zero (attendance) period insertion. Subjects could be entered considering subject in which classroom, single or double duration consecutively, periods per week per subject. Periods could be entered with considerations of maximum number of consecutive periods per teacher. Teachers could be placed with considerations such as class should not be assigned when teacher is not free i.e ABC teacher should not be given any class on Monday. XYZ teacher should not get 1st and 2 period on all days etc. Also considering teachers getting x number of maximum periods, minimum/maximum periods per day, limit number of consecutive periods. Automatic Reports for Printing, Website: Reports for website could be generated for the following: Summary timetable for classes Summary timetable for teachers Summary timetable for rooms year wise time table Teacher wise time table All classes assigned to a teacher ( no. of periods per week bifurcations) Total number of periods subject wise Checking of total Working Hours per week details for the teachers PROCESS FLOWS ER-DIAGRAM DATA FLOW DIAGRAM Context Level Diagram Level 1 DFD CLASS SCHEDULER is a system in which automatic timetable is generated by considering various constraints in the system. It also provides the login facility. System takes the required data provided by class coordinator and performs function to generate time table.

Professor can request for modification which is forwarded to system by coordinator system generates the alternate timetable, coordinator views the generated timetable and accepts or rejects the modification. If modification is accepted then the received timetable is stored in database. If the request is rejected then it is informed to requestor that request cannot be processed. This all activities are shown in the data flow diagram (Level 0) also called as context free diagram. Level 2 DFD INPUTS: It takes various input required by system that are professor information and various data required about that professor. It also takes input of subjects and the relevant information required. The classroom and lab information are also provided. This all data are provided by coordinator. GENERATION OF TIMETABLE: It takes the information provided by the coordinator and consider the various constraints provided. It generate professor schedule and the respective schedule is entered in the class schedule, while generating the schedule it also checks that no timeslot redundancy occur i.e; no single slot is allotted to a two or more professor. Two type of timetable is generated: class wise and professor wise, this both timetable are stored in database by this process. This stored timetable is used as and when required by the users. DISPLAY TIMETABLE Whenever user login the system it provides various option of displaying timetable. User select the required options , the request is then analyzed by the system and in accordance to the request made the required timetable is displayed. The system provides the online view of timetable. MODIFICATION After the time table is generated the provision is made to view them in various options , timetable is displayed as per the user requirement. The professor views the timetable and if required he/she request for modification. This modification request is forwarded manually to the coordinator which in turn is forwarded to the system. The system then generates the alternate timetable .this alternate timetable is then viewed by the coordinator. He then decides whether the change is propagated or the request cannot be considered. If request is not considered then it informs the requestor about it.

CONCLUSION This study has examined the possibility of implementing the concept of assignment of lectures for the class scheduling process. The advantage of this system is that it would be able to applied not only to similar scheduling problems and be extended to various types of problem sharing the same concept. The model has to be able to reduce the number of activities in the scheduling process.

Object Oriented and Modelling Concepts Car Parking

Object Oriented and Modelling Concepts Car Parking Akila Kanishka Gangodage   At the present time parking is the major requirement of the people. And also there are limited spaces to park vehicles in the city area. Therefore car park systems should have proper management system to control the day to day activities. Peoples time is very valuable their time cant be wasted. People cant spend lot of time in the car park to park their vehicles. Traditional car parking systems are mainly best on human. That kind of systems use human to control activities of the car park, as example collect the money, generate the tickets, check the remaining space etc. But to do all these activities are taken lot of time and it is not efficient process and also this type of systems are no longer applicable for the modern society. Modern systems are using computers and software systems to manage and control the activities of the car park which can be interact by people time to time According to fact which are discuss above, a car park need a proper system that can manage and control all the day to day activities of car park efficiently Generate tickets. System should have generate two type of tickets. For ordinary customer and season customer. Season tickets should be issued to defined individual or company, a ticket need to be included contact number address and each season ticket should be valid for the given time period and issue date and expiry date should be display on the ticket. Ordinary tickets should be issued time period at the car park. Accept tickets. For the ordinary customers, if car park is full, no tickets should be issued. Each and every ordinary customers ticket should have bar code on it. When ordinary customer is leaving the dates or time should be the same, if not the ticket is ejected. For the season ticket holder, a check is made that the season ticket is valid for this car park and has not expired. Season ticket holder should not be recorded as having already entered this car park and not left. When the car park is full, tickets should not be issued from the control pillar. Handle payment. Payment can only be card (Master/Visa/Debt) or cash (50c, 1$, 2$, 5$, 10$, 20$, 50$). For ordinary customer, according the duration of the stay in the car park charge should be calculated and displayed. System should identify the notes and coins which are inserted by customer and the value added to an accumulated amount. When that amount exceed the charge, the ticket should be validated. And also change should be given accordingly. Invalid notes and coins can be identified and returned back to the customer. Control boom gates. The barrier should be raised, after the customer pull the ticket from the control pillar. Car should be detected by the sensor on the other side of the barrier when it has passed then barrier should be lowered. When the customer reach the exit barrier should be detected by a sensor and then the control pillar should allow the customer to check the ticket and after complete the payment the barrier should be raised. If this process consume more than fifteen minutes, the attendant can view the details of the ticket on his computer and should be able to control the barrier Record problem in a log book. If there any fault of equipment or any other aspect of the operational system the maintenance company must be notified straight away. The system should be able to generate static report of all faults. Manage security. The security guard should be able to put his or her card into card reader and arrival date and time should be recorded. Leave time also should be recorded as the same. The system should be able to handle one or more security companies. Hardware resources. Computer Boom gates Ticket scanner Printer Security camera Sensor Software resources. Windows Operating System. Need a user friendly and lightweight operating system for the computers for manage all other software. Browser. Since the developed system is interacted with web the computers require browser in order to use it. Database. System require a central database to store and process all the data. Barcode reader software. By using this software the system can identify each and every barcodes which are on the ticket. Payments handling software. Using this software system can detect and identify the notes and coins get the accumulated amount. Financial resources. The City Administration is fund for the project. Human resource. Most of the activities of the car park is done by the system itself but to be the complete system the car park system need human interaction. So system need to at least 10 peoples to proceed, Five peoples for the IT department. Three developers, one Tech Lead and one Project Manager Three peoples from the client company. Tow from the security company and one from the maintenance company One investor User There are some possible risks that can be happened while this car park system is using. Natural disaster. The significant increase in disasters of a natural and/or technological origin seen today has serious consequences for CI, the population, the environment, and the economy. These consequences have been exacerbated by the development of sociotechnical systems such as transport networks and industrial plants, their interdependencies, and their sensitivity to major hazardous events. (Farid kadri, Babiga birregah Eric chatelet, 2014). Natural disaster like Earth quick, flood, fire, and tornado can be done major impact for the hardware, software and human resources of the system. As an example when Earth quick happened it can be effected for the hardware devices like CTTV camera, boom gates control pillar, computer etc. and also it can be harm people and vehicles in the car park. Hardware failure. Hardware failures are permanent failures that occur over a period of time (Asim kadav, Matthew j renzelmann Michael m swift, 2009). Hardware devices can fail, but many systems assume they do not. When confronted with real devices that misbehave, these assumptions can lead to driver or system failures (Roozbeh bakhshi, Surya kunche Michael pecht, 2013). For an example if a boom gate will not work, cars cant enter the car park. Software failure. Sometime software need to be updated for work with the new technologies Database crash. Valuable data can be lost because of database crash Electricity failure. This kind of systems are mainly depend on electricity. So electricity failure is major risk that this system have to face. Lack of trained employee. Sometime it can be hard to fine trained employee to work with the car parking system. Propose outcome of this project is, that provide the efficient and effective car parking system for the people and avoiding unnecessary time wasting at the car park. And also this car parking system is very simple to control and manage and regulate for the city administration and can get higher business value in the city area. By introducing this new car parking system with new technology can gain lots of benefits for the company. Since parking is becoming a major requirement of people who come to the city for office, busyness, studies, work, shopping and hospital etc. this kind of efficient parking system can get high demand rather than other car parking system. Maintaining the parking system is becoming easier. Because of any fault of equipment can be notified by the system for the Maintenance Company. Another main benefit of car parking system is can operate with low manpower because of most of the activities of car park can be managed by the system itself therefor company can save lot of money Safety and security of drivers and cars are very high because system has security management system itself. Therefor company can earn customers trust and can have regular customer base. Another benefit of this system is system can keep the record easily in database and use them any way company want. Company use record for security purpose, financial purpose and maintain the statistic. Using this kind of car parking system the City Administration can have maximum utilization of space in city area. References Asim kadav, Matthew j renzelmann Michael m swift.(2009).
