A network model is a subject that one can encounter in their computer science course. It is also pursued by students as a separate diploma course. Its importance has made it immensely popular in the academic arena. A student pursuing a network model course has to take on several academic assessment parameters. And assignments weigh a lot in the academic assessment of the student. It differs from university to university, but it has been observed that an assignment can weigh anywhere from 20 to 60 percent of your final assessment. Writing an assignment on this subject can be a tough task for the students; especially given their lack of experience.

The network model was developed by Charles Bachman. Network Models are basically database models that are used to represent objects and their relationships to each other in a flexible manner. A generalized graph structure is formed allowing each record to have several parent and child record which form a network model. The schema in network model, which is seen as an arc, is not limited to being a lattice. Hence, network model allows a natural way of modeling of relationships between different entities, which is as opposed to the hierarchic model. In spite of the advantages of network model, it is not widely used because IBM uses the hierarchic model in their products such as IMS and DL/I. In fact, relational model replaced the network model since it has a higher level of declarative interface. The network model is used in some popular database systems such as, IDS or Integrated Data Store, IDMS or Integrated Database Management System, RDM Server, RDM Embedded, Univac DMS-1100 and Turbo IMAGE, etc. Our writers in our network model assignment help provide a detailed essay on the various topics of this subject.

For small flow rates, the volume flow rate Q through a small triangular-section tube of side W and length L is a function of dynamic viscosity , pressure drop per unit length p/L and W. Using Buckingham pi theorem, express the relation between variables in a non-dimensional form .
The first part should be solved manually, and the second part should be done by using abaqus software. Consider a first-order triangular element, if we know the coordinates (x,y) and the displacements (u,v) at the nodes as follows: Node 1: (x1, y1) = (3.0,3.0), (u1, v1) = (0.012,0.006) m Node 2: (x2, y2) = (2.0,4.0), (u2, v2) = (0.015,0.005) m Node 3: (x3, y3) = (1.0,1.0), (u3, v3) = (0.010,0.008) m a) Find the interpolation functions for this element. b) Calculate the displacements (u, v) at the points (4, 3) and (3, 2).
Design an efficient retaining wall to be used along the rear of excavated area of the tank. Depending on depth of cut and height of soil to retain,dimensions for both stocky and slender retaining wall will be designed. Retaining walls will be designed to resist against three major failure modes including overturning, sliding and bearing. Based on the design of retaining walls to resist mentioned failure modes, optimal dimensions for the most economical shape of retaining wall will be proposed.
Determine the deflections and stresses in a loaded Pilatus PC/9 wing using finite element computational modelling. The aircraft wing can be simplified using appropriate beam-plate representations. You must decide how to represent the wing to provide meaningful results. This is a major focus of the assignment and much detail and explanation is expected for all choices in your numerical calculations.
The aerodynamic lift of the wing is described by the distributed load of 2w x 300 1 0.04 N/m. The mass of the wing is 27 Kg, and its center of mass is located 2 m from the wing root R. (a) Determine the magnitude of the force and the moment about R exerted by the lift of the wing. (b) Determine the reactions on the wing at R.
Few tasks related to different cipher processes, from ancient Caesar cipher to digital signature of files. This is a great way to practice and fully comprehend concepts of hash, public key, private key and cracking and encryption. In this case we based some of the task on Linux commands and the rest required only simple math calculations
Explain in your own words the purpose of the command in the context of the assignment question. Also, you need to explain in your own words all terminology used—as if you were explaining to an average user. Show that the command worked—either from its output or the output from another command. To capture text output from programs you will have to redirect the output to a file or use the command script.
Design and implement a secured network infrastructure that ensures high availability, reliability, scalability, performance and security to support GB services. This requires 1) the design of the network; 2) the delivery of a comprehensive network security plan; and 3) Security technology implementation - proof of concept.
You are required to design a simple CMOS circuit consisting of a two-input NOR gate. You are required to show the layout (plan view) of the circuit, after calculating the aspect ratio (W?L) of the transistors. The Layout of the circuit includes the VDD and ground lines.
