Class Model

Chúng tôi trình bày một phương pháp sử dụng Unified Modeling Language (UML) để phân tích thiết kế hệ thống (PTTKHT) quản lý tuyển sinh tại Đại học Đà Nẵng. Quá trình PTTKHT gồm các bước từ khâu khảo sát thực tế, xây dựng mô hình dòng dữ liệu, xác định các tác nhân, các đối tượng, các lớp để xây dựng các biểu đồ như biểu đồ trình tự, biểu đồ lớp, biểu đồ đối tượng, biểu đồ các trường hợp sử dụng. ...

Real world concepts can be modeled in a computer program The program is made of objects with certain properties and operations that the objects can perform It is not important how an object is implemented, but what it does Every object is responsible for carrying out a set of related tasks. A class can contain data declarations and method declarations

Model Predictive Control (MPC) refers to a class of algorithms that optimize the future behavior of the plant subject to operational constraints. The merits of the class algorithms include its ability to handle imposed hard constraints on the system and perform on-line optimization. This thesis investigates design and implementation of continuous time model predictive control using Laguerre polynomials and extends the design approaches proposed in to include intermittent predictive control, as well as to include the case of the nonlinear predictive control.

The thesis investigates the nature of this developmental process by employing a constructivistinterpretive research methodology and using qualitative research methods. The empirical data was drawn from group discussions and face-to-face interviews with two distinct cohorts of women. The first cohort comprised twenty-two participants, of which five were adolescent women aged fourteen to sixteen years. The thesis focused only on examining those women who were financially successful and not others.

Although the research direction on NSFD schemes for differential equations have achieved a lot ofresults shown by both quantity and quality of existing research works, real-world situations have always posednew complex problems in both qualitative study and numerical simulation aspects. On the other hand, there aremany differential models that have been established completely in the qualitative aspect but their correspondingdynamically consistent discrete models have not yet been proposed and studied

The simple 3-3-1 model considers the simplest lepton sector and the scalar sector. This setting leads to natural components of the inert fields such as scalar inert fields and right-handed neutrino.

Quantifying the multiple processes which control and modulate the extent of oral bioavailability for drug candidates is critical to accurate projection of human pharmacokinetics (PK). Understanding how gut wall metabolism and hepatic elimination factor into first-pass clearance of drugs has improved enormously. Typically, the cytochrome P450s, uridine 5′- diphosphate-glucuronosyltransferases and sulfotransferases, are the main enzyme classes responsible for drug metabolism. Knowledge of the isoforms functionally expressed within organs of first-pass clearance, their anatomical topology (e.

Oligomerization into multimeric complexes is a prerequisite for the chaperone function of almost all a-crystallin type heat shock proteins (a-Hsp), but the molecular details of complex assembly are poorly understood. The a-Hsp proteins from Bradyrhizobium japonicum are suitable bacterial models for structure-function studies of these ubiquitous stress proteins. They fall into two distinct classes, A and B, display chaperone activity in vitro and form oligomers of  24 subunits.

Acyl-CoA dehydrogenases constitute a family of flavopro-teins that catalyze the a,b-dehydrogenation of fatty acid acyl-CoA conjugates. While they differ widely in their spe-cificity, they share the same basic chemical mechanism ofa,b-dehydrogenation. Medium chain acyl-CoAdehydro-genase is probably the best-studiedmember of the class and serves as a model for the study of catalytic mechanisms.
