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

Behavior Diagrams Definition: Behavioral models describe the internal dynamic aspects of an information system that supports the business processes in an organization. During analysis‚ behavioral models describe what the internal logic of the processes is without specifying how the processes are to be implemented. Later‚ in the design and implementation phases‚ the detailed design of the operations contained in the object is fully specified. Use case diagrams are behavior diagrams used to describe

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

National Postsecondary Student Aid Study (NPSAS)‚ this study examines access to postsecondary education by individuals in different income and test score groups. While many studies have found a statistically significant effect of income on college enrollment‚1 less attention has been paid to the effect of family income after controlling for student achievement. This study specifically addresses this issue. We also explore differences in the decision of whether or not to attend PSE or in the type of

Our Online student enrollment system enables students to enroll into their subjects prior to the commencement of their semesters. This enrollment system not only allows international students to enroll through internet without traveling to the campus but also incorporates the business rules. These business rules cover a wide range of regulations and policy such as subject pre-requisite‚ student’s payment status‚ course coordinator’s decision and the correspondence of students’ seniority to the intended

convenient to do online enrollment because one does not have to actually got to the school and cram in there together with the other enrollees. All it takes is a computer that has internet connection‚ and one can instantly enroll after following the instructions in the site. Online enrollment is to a certain extent in a new fad. Not many‚ in fact‚ only a handful of schools in the Philippines‚ particularly in Manila‚ cater to online subject enlisting and enrollment. Many await the enrollment schedule of the

Interaction Diagram:- means a situation or occurrence in which two or more objects act upon one another to produce a new effect in an understandable format. Interaction is a part of dynamic behavior of the system represented in UML by two diagrams known as Sequence diagram and Collaboration diagram. Meaning of Collaboration Diagram:- also called a communication diagram or interaction diagram‚ is an illustration of the relationships and interaction between entities or objects in the Unified Modelling

smoothing. In our work on power supplies so far we have determined how to calculate the peak value of the output voltage from an rms value‚ and how to use half-wave and full-wave rectification methods to change a.c. into variable value d.c. The next stage is to smooth out the pulses of variable d.c. into a more regular output that might be suitable for use in electronic circuits. The component needed to assist us with this stage of the process is the capacitor. You should remember that from Topic 2
