From the study, a simulation model is suggested for simulating the Waterfall software development life cycle using Simphony.NET. In fact, the Simphony.NET is useful because it provide a ranked modelling feature which a project can be represented by an abstracted model at a higher level that contains a limited number of modelling elements and relations. The Waterfall model is enable to understand and easy to use. Furthermore, the phases of this model are processed and finish one at a time without overlap. The results or outcomes.
Then the machines should be classified, and a proper one will be chosen to be modified. Indeed, a deep search need to be done on what is the latest modification has done on the machine, and what is the results. The problems and disadvantages of other researcher should be considered. A completed plan should be set with the supervisor at this stage. At earlier stage of the research, mechanical and electron sketch should be done with computer simulation.
In the field of HCI, heuristic evaluation is a technique for computer software that supports identifying usability problems in the user interface design based on a set of design guidelines, usability principles and heuristics (6). Heuristic evaluations can determine structural problems and root causes of the usability failures and issues; furthermore, it’s a cost-effective method that providing effective insights and feedbacks to designers and developers (12). Many studies have shown that heuristic evaluation can predict major usability issues that might potentially occur throughout the usability tests (18,
The learning problem consists of inferring the function that joins the input and the output in a predictive fashion, such that the learned function can be used to predict present output from future input. Depending of the type of output, supervised learning problems are either problems of regression or classification. If the output takes a continuous range of values, it is a regression problem. For eg, in Ohm’s law, a regression could be performed with voltage as input and current as output. The regression would find the depencency between voltage and current to be such that
CHAPTER 1: INTRODUCTION Inverted pendulum systems represent a significant group of mechanical systems used in control education with a number of practical applications. It is evident that the stabilization of a walking human or robot, a launching missile or the vertical movement of a shoulder or arm can all be modeled by some kind of an inverted pendulum system. The diversity of modeled systems is reflected in the variety of available inverted pendulum models. These may differ by: • the type of actuating mechanism – the system base is moving either in a single axis (classical pendulum system) or in a plane (rotary pendulum system) • the number of pendulum links attached to the mechanism – single and double pendulum systems are common control
The inverted pendulum, being highly unstable and non-linear has remained under consideration excessively for control studies. Many challenging effects are to be accounted for and various control techniques have been applied considering the nonlinear, unstable, non-minimum phase and under-actuated nature of the system . The reason behind such an extensive study of inverted pendulum problem is its vast applications regarding control and stabilization in the engineering systems for example industrial control studies and biomechanics studies like rocket launching system, missile system, a highly unstable fighter air-craft system, 2 wheel self-balancing robot, bipedal dynamic walking robots etc. There are various cases of inverted pendulum which are considered for research purposes i.e single pendulum, single rotary pendulum, double side by side pendulum, double pendulum and triple pendulum problems
Pragmatism is a fundamental model or scheme that organizes our observations and makes sense of them (Allen Rubin & Babbie, E.R, (2011). In order to make the sensible study, the researcher will apply multi paradigms to meet the requirements of the research. This is because each paradigm separately has its own disadvantages. A combination of paradigms in the single study will help to reduce the weakness of the single perspective. Different paradigms in the single study provide an opportunity for the researcher to use variety of approaches and designs so that the study will compile both the authenticity and genuine information.
The goal of manual testing is to make the application error and defect free and to check whether the software is working as per the given requirements. In this testing the user(tester) will take the role of the end user and tests the application which is under the test to identify the unexpected behavior and defects in the software. In the manual testing there are different types of testing. They are:1. System testing 2.User acceptance testing 3.Unit testing 4.Integration testing.5.
Figure 1: Angle of Decision Theory From these theory, it also involved Decision Support System (DSS) in their process to make it more effective when solve the problem. Decision Support System (DSS) is the collection of people, procedures, software, database and devices that organized when making decision or solve problem (Ralph & George, 2011). DSS is more focusing on the effective decision making when facing semi-structured or unstructured problem happened in information field. According to Ralph and George (2011), the characteristics of Decision Support System (DSS) are allows users to access
