When researching about design patterns in programming you instantly realize that they can be very useful in implementing a certain piece of code or just having it as a useful programming practice. Design patterns are created to solve common programming problems that keep on recurring in a certain context when designing a program. There are several types of design patterns that are all split into several groups. Some of these groups are Algorithm Strategy Patterns, Execution Patterns, Structural design patterns, Creational design patterns, Behavioral design patterns and Computational design patterns. Each of these sub groups of design patterns goes about solving a different type of problem. Design patterns can be beneficial because of the simple fact that they are solving programming problems that would usually surface when programming.
The type of design pattern that I chose to further research falls under the Creational design pattern group. Creational Patterns are meant to solve problems that deals with object creation instruments, which means to create objects in a way that is appropriate for the specific circumstance.
I have chosen to research the Singleton design pattern more in depth. The Singleton design pattern addresses the problem of sometimes only needing to have one instance for a specific class. The intent is to ensure that only one instance of the class in made and to provide a global point of access. Although this design pattern is one of the simplest that exist, it really can have a huge impact. The pattern involves only a single class (hence the very creative name) which is responsible to instantiate itself to insure that it will not be instantiated again. An example of this design pattern is when we are workin...

...hould only be instantiated once and having another instantiation would lead to a lot of bugs and errors. If we use the singleton design pattern we are able to still globally access the User Manager and retrieve information such as user ID’s or be able to sign a user up as needed. But with the Singleton pattern we won’t need to worry about re instantiation, because it’s just not possible.

1) I believe that my theoretical curves don’t really match like figure 4 but then again it somewhat does. My immigration curve and extinction curve do hit each other once, but not like in figure 4 where they hit each other twice. Also my extinction curve is going up like in figure 4 and my immigration curve is going down just like in figure 4. So I guess you could say that my curves represent the curves on figure 4.
An archetype, by definition, is “the original pattern or model of which all things of the same type are representations or copies” (Mirriam-Webster). In other words, an archetype is a perfect example of something. Northrop Frye says that "archetypes are the recurring patterns
I am not sure were the dealer for the total for the parts on the invoice. I received the email below from Javier and it has the total amount for the equipment he needs. Can you have someone that knows about the installation end of it look at it and see if it is correct? If approved will you be providing the equipment credit?
Upon reading information about REU AMI for summer internship, I have a mind of expertise in technology can provide people with disabilities that make easier for them to have access to the framework of information library. Not only accessibility of information, interaction with technology is an essential to those who want to gain knowledge of information they desire to learn. Aside from that, I have been involved with team in Thinking Cap funded by National Science Foundation since January 2015. The goal is to evaluate and analyze the challenges that Deaf and Hard of Hearing students experience in the Statistics course. My initial responsible was to provide feedbacks and suggestions on videos and PowerPoints that were helpful for students complete a difficult statistics topic. As of now, I am currently

The reason for this pattern is the same as that that was made in the
Over the last four years of studying architecture, I have seen the power that it has to shape communities, shape lives, and to create new ways that people interact with each other. The way architecture can help enhance living and allow for creation of new interactions of people is one of the reasons I find the subject so interesting. The way architecture can shape a whole culture and the way that the culture then in turn shapes the architecture is fascinating to me. Architecture is also not a static subject, it is constantly evolving and adapting with time to take on new forms, create new spaces, and to provide commentary on the history of our time on Earth. The depth that architecture has, and the evolution of the subject is something I have fallen in love with through my study of it. However, when I first started out studying architecture, I had no idea of the depth that the subject had, and it was an incredibly daunting realization; however, it was as equally exciting. I have always had a love for learning and architecture has just fueled that fire. Even after completing my bachelors degree, the learning has not stopped. I get to learn something new about architecture daily, and getting to say that is an opportunity I am thankful to have. It is not just about the learning however, its
John was chosen for individual therapy due to his motivation for change seemingly to be the highest amongst all family members. As such, a deeper relationship is to be developed between he and I in the hopes of promoting and fostering a greater differentiation of self. Furthermore, it is my intention to assist John with de-triangling to avoid further negative producing emotional fusions. Psychoeducation will be provided for healthy family triangles, differentiation of self, and how viewing family from a multigenerational context can help ward off maladaptive behavioral patterns from repeating. We will explore all aspects of both his immediate and extended family searching for key features that have promulgated across generations.
Design has established itself as core elements in societies helping countless communities build infrastructure, invent new ways to better living conditions and create design desirable for consumption hence bettering the economy. Though this is a positive, most designers of the 21st century use their skills and their designs alike for those who can afford it; designing for what’s in fact the minority, 10% of the world’s population. The reason why developmental aid and design for development is essential to improving standards of living for those who live in developing countries, but to also bridge the gap between the rich and the poor. Ilse Oosterlaken (2009, p.100) equates most designs for development that use a `participatory' process as having a limited, user-centred approach; and suggests instead a more universal design approach, which she calls ‘capability sensitive design’. This essay will illustrate designs that have contributed to developmental design through capability sensitive design approach, considering sustainable design that are not only better the environment, community health and social welfare but the country’s economic standing. Through evaluating each example’s potential for real, sufficient, diverse and lasting value for the targeted users we can determine each design’s efficiency.
3. The pattern diagram is very essential in creating a crochet product. This serves as the guide on how he will follow the instructions and outline of the design. Most patterns are usually easy to follow especially if the person is highly skilled n crocheting. For most beginners, there are patterns, which are more basic and simple. They are especially designed for them to practice and understand simple patterns of crochet products.
Instructional Design is a systematic approach to design, evaluation and management of instruction. It helps to facilitate learning in an effort to improve. There are many models that have been developed to assist in the design of instructional materials. This paper will compare three: ADDIE, ASSURE and Kemp with a focus on online learning.
Spatial pattern- This is a perceptual structure, placement, or arrangement of objects on Earth. Which includes the space between objects. Spatial patterns could be recognized either in a line or by a clustering of points.
The Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The key is to organize the design process in a way that clients, analysts, programmers and other involved in system development can understand and agree on. The UML provides the organization. The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thin to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.
Throughout this term, my fellow classmates and I have had a chance to participate in a group project with two or three of our peers. The general topic was a vivid problem in a industry. Our class had a very wide and diverse sets of topics: from Styrofoam, to industrial hacking, to corruption in an influential international organization like FIFA, and so many more. Our group decided to develop a project named “Outsourcing and the price we pay for brands”. The name itselves is somewhat self-explanatory, however the problem is so much more complicated and interesting. In this paper, many struggles and concerns, of the group and of my my own, will be unfolded as I reflect the progress of this project.
The article Guest Editors' Introduction: Algorithms and Today's Practitioner is about the use of algorithms in the world of software engineering. An algorithm is a set of rules that need to be followed in problem-solving operations .The practice of finding and using new algorithms had really died down until someone almost found the solution to the P=NP problem. The P=NP problem asks if a problem that can be verified by a computer quickly can be solved quickly by a computer. This boosted the interest of “algorithmic advances.” Since this increase in interest of algorithms, more people have wanted to become software
