...A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem. An important class of computer operations on some computing platforms is the accepting of input from human operators and the output of results formatted for human consumption. The interface between the computer and the human operator is known as the user interface. A computer is like a brain which can think, calculate, retrieve and organize information for its human master. This brain is supplied with parts that provide allow for input to it and allow it produce output for presentation to the one using it. Central Processing Unit The thinking part of the brain of the computer is the CPU or Central Processing Unit. This component provides all the control and manages calculations and manipulation of data. Computer manufacturers are always trying to squeeze more speed and multiprocessing capability (doing multiple things at the same time) out of it. This has led to the dual core or multiple core CPU which is popular today. A core is basically a computer so that a dual core computer is really 2 computers in one. Computer speed is usually measured in GHz which means Gigahertz which in turn mean billions of cycles per second. The basic idea is that the higher the number of cycles, the faster the computer is. Today the...

...are entitled to duty exemption and drawback on taxes paid on utilities and, in some case, on the fuel consumed in the production process. Eligible exporters can claim their drawback by filing their claim with the Duty Exemption and Drawback Office (DEDO), which is an agency under the authority of the National Board of Revenue. The Customs Act, 1969 and the VAT Act 1991 governs the process. While Chapter VI of the Customs Act 1969 provides many of the guidelines, since the promulgation of the VAT Act 1991, drawback can also be claimed on inputs under Section 13, Rules 28, 29, 30, 31, 32, 32(a), 33 and 34. Additional SROs that guide the process include SRO 154 (June 9, 2005) and SRO 157 (June 9, 2005). Eligible exporters can enjoy this facility under two broad categories – a duty exemption or a duty drawback. Under the duty drawback system, exporters get refunds of the duties and indirect taxes they have paid on imported inputs. Duty may be refunded in three ways: a) actual drawback, b) national drawback, and c) flat rate drawback. Due to fewer complications and ease of operation, the flat rate system remains the most preferred method of refund. There are also two other ways of making such refunds: individual and fixed drawback systems. Individual drawback systems refund the duties and indirect taxes paid by the firms, while the fixed drawback systems refund the estimated duties and indirect taxes that enter the cost of production of exports according to a preset schedule...

You can add additional ports by connecting a USB module to motherboard pins. This module takes an expansion space (but not a slot). A PCI/PCIe adapter can also be installed to provide additional ports. Cabling from the power supply to the adapter might be required to provide power to the new USB ports. * • Up to five USB hubs can be daisy-chained to one port. Upstream ports connect to the computer or another USB port. Devices connect to downstream ports. * • USB hubs can be self-powered or bus powered. * • IEEE 1394 devices do not have to have a computer port and can be cabled to each other; otherwise...

...LAB - RADIAL FLOW REACTION TURBINE Objectives: To measure volume flow rate, input head, hydraulic input power, torque, brake power & turbine efficiency when the brake force is increase Theoretical Background: Radial flow When a fluid flows radially inwards or outwards from a centre, between two parallel planes as in Fig. 6.21, the streamlines will be radial straight lines and the streamtubes will be in forms of sectors. The area of flow will therefore increase as the radius increases, causing the velocity to decrease. Since the flow pattern is symmetrical, the total energy per unit weight H will be the same for all streamlines and for all points along each streamlines if we assume that there is no loss of energy. [pic] Figure 6.21 If v is the radial velocity and p is the pressure at any radius r, H = p/ρg + v²/2g = constant …………………………(6.31) Applying the continuity of flow equation flow and assuming that the density of the fluid remains constant, as would be the case for the fluid, Volume rate of flow, Q = area x velocity = 2πrb x v where b is the distance between the planes. Thus, v = Q/2πrb and substituting in equation………(6.31) p/ρg + Q²/ 8π²r²b² = H p = ρg [ H – ( Q²/ 8π²b² ) x ( 1/r² )] …………………..(6.32) If the pressure p at any radius r is plotted in Fig. 6.21(c), the curve will be parabolic and is sometimes referred to as Barlow’s curve.

There are several differences between hostels and hotels, including: * Hostels tend to be budget-oriented; rates are considerably lower, and many hostels have programs to share books, DVDs and other items. * For those who prefer an informal environment, hostels do not usually have the same level of formality as hotels. For those who prefer to socialize with their fellow guests, hostels usually have more common areas and opportunities to socialize. The dormitory aspect of hostels also increases the social factor. 1.2 STATEMENT OF THE PROBLEM The growing number of students in higher institutions all over the world has posed a lot of accommodation problem on the part of students and school management. Students at the beginning of each session waste half of the semester looking for accommodation. The few hostels that exist in the higher institutions are not properly managed. Statistics of the number of rooms required to match the growing number of students are farfetched. We have got four hostels in our institute, which consist of two boy’s hostel and two girl’s hostel. All these hostels at present are managed manually by the hostel office. The Registration form verification to the different data processing are done manually.
