The Use of Cooling Curves in the Determination of the Phase Diagram for a Lead-Tin System V.O.L.Tabell Department of Mining‚ Metallurgical and Materials Engineering University of the Philippines‚ Diliman vo_tabell@yahoo.com Abstract This paper discusses the use of the cooling curves in the determination of the phase diagram of a Lead-Tin system. The inflection points of these cooling curves were obtained by melting a series of mixtures of lead and tin at varying compositions. These critical

Class Diagram A class diagram is at the heart of UML. It represents the core purposes of UML because it separates the design elements from the coding of the system. UML was set up as a standardized model to describe an object-oriented programming approach. Since classes are the building block of objects‚ class diagrams are the building blocks of UML. The diagramming components in a class diagram can represent the classes that will actually be programmed‚ the main objects‚ or the interaction between

Both Class Diagrams and Use Case Diagrams are used in the requirements determination of object oriented development. Object oriented development is an approach to system development that uses the object as the basic unit of systems analysis and design. Use case shows the relationships among actors and use cases within a system. Class diagrams are widely used to describe the types of objects in a system and their relationships The purpose of Use case diagram is that it shows the interaction

2.3 Ishikawa diagram In 1960s‚ Professor Kaoru Ishikawa has introduced Ishikawa diagram. This diagram also called fishbone diagram or cause and effect diagram (Ishikawa 1976). Since this diagram is inception‚ it has gained tremendous of popularity to identify the root cause of the variety of problems (Hossen et al. 2017). Besides that‚ Ishikawa diagram often called as fishbone diagram is because it can help in the brainstorming to determine the possible cause of a problem and also sort the ideas

Objective At present the health care system of Bangladesh faces major challenges. We are unable to provide even primary medical care to our people let alone secondary and tertiary medical care. The current scenario of information flow in most of the hospital in Bangladesh presents a paper based‚ time consuming‚ inefficient system leading to problems of inefficient utilization of resources and problems to patients. All these problems and poor coordination – are closely connected to our failure to

BAR DIAGRAMS Bar diagrams are one of easiest and the most commonly used devices of presenting most of the business and economic data. These are satisfactory for categorical data or series. They consist a group of equidistant rectangles‚ one of each group or category of the data in which the values or the magnitudes are represented by the length or height of the rectangles‚ the width of the rectangles being arbitrary and immaterial. These diagrams are called one-dimensional because in such diagrams

Although this system may vary‚ each company records some type of data‚ analyses it‚ and uses the feedback to make decisions or changes through tout the company. This is having an information system within the company. Throughout this essay‚ information systems will be discussed and applied to information theory. To begin‚ it is important to understand each component of an information system. There

and explain a Use-Case diagram for a Library Management System. Introduction: Capturing the dynamic behaviour of a system is one the key aspects to create a model. Dynamic behaviour means the behaviour of the system under operation. Use case diagrams are used in Unified Modeling Language‚ a standard modelling language for the modeling of real-world objects and systems. A use case diagram is to explicitly define the working of a system with in a system boundary. Each system is primarily divided into
