Much attention has been paid to the diagonal flips in maximal planar graphs. In this paper, we firstly focus on the properties of the unflippable edges in maximal planar graphs, and propose the concept of K4-embedding. Also, we prove that for a maximal planar graph G with order n(⋝ 5), an edge e ∊ E(G) is unflippable if and only if e is either incident to a 3-degree vertex or a supporting edge of...
The past decade has observed a continuously increasing internationalization of higher education institutions. Multicultural instruction is challenging for educators and students alike. Japanese universities follow the same trend, striving to become more and more internationalized, classes need to accommodate both local, Japanese students, and international, foreign students. Based on the author's...
Scoring short answer question (consisting of at most 100 words) requires a special treatment, particularly on the term weighting process. With such limitation, it is therefore infeasible to have term weighting with term frequency model because the frequency of term appearance is very rare. This paper proposes a new method, named Weighted Cosine Coefficient. The experiment result shows that Weighted...
Refactoring has been widely used to improve software design. Refactoring is applied when a bad smell is detected. Several bad smells might be present in the code. In this paper, we conduct an empirical study to find if the order of applying refactoring has any impact on the quality of the final code. We run six experiments by applying three refactoring methods in different orders and evaluate the...
Since, both the business and technological environments changed at an increasing rate, flexibility has become a main and important reason for project management in software developing regions. Methodology plays a significant role in flexible development of software. However, the question is, How should we do it? The web technology, communicating network technologies and system hardware is in rapid...
Prepaid Energy Meter has been implemented in several countries. In fact, the disadvantage of the system is the behavior control of the users. Recharging should be carried out on the meter. The problem arises when the consumers leave and the electric pulses discharged. Therefore, a system is needed to control the electrical pulse wherever they are. Prepaid energy meter is proposed and simulated by...
Software development initially used traditional methodologies which have been in the mainstream until the advent of agile methodologies. It is often thought that as traditional methods would be eventually replaced by new methods, it still remains the closest link to a naturally progressive route although the mind-set wants to get rid of the old and get in with the new. But it is not the replacement...
The goal of any automated requirement prioritization process is to reduce the difference between the true and estimated ranking. It is arguable that to what extent, using stakeholders' feedback will reduce that difference. Moreover, incorporating requirement ranking functions such as value, cost, risk, etc. along with the feedback is another concern. This paper proposes a scheme for requirement prioritization...
Software is increasingly developed in global projects, and such projects are challenged by distance, different time zones, and cultural differences. Knowledge management is central to ensuring effective development of a product with the right features and the right level of quality. A central question then is what knowledge management approach to apply in global software development. This article...
Energy engineering is a new multi-disciplinary engineering field to develop innovative renewable energy (RE) systems. On other hand software engineering has recently emerged as a new engineering field in a continuing evolution. Software engineering is a discipline whose aim is the production of high quality software, but lacks maturity compared to other traditional engineering fields. Much of the...
Requirements change management is a vital activity of the software development and even after maintenance. When we change one requirement it effects the other requirements of the system. A proper impact analysis maintains a repository of changing requirement, reusing previous experiences and reduces rework effort, is also essential for better requirement change management. There is also a need of...
This workshop will address challenges faced by clinical engineering sectors and how Information Technology (IT) could be a great ally. A big tendency is the use of radio frequency identification technology in hospitals. How has the clinical engineering been preparing for it? Furthermore, how will the IT sector deal with this technology? The aim is to unite these two great players in a common goal,...
The traditional methods can't describe semantic relation of function of component, obstructing components from being applied by users. So description model of component is founded by means of ontology, in order to carry out semantic extending of retrieval of component. The method that figures out similarity value between function of component and requirement of users is presented. It helps users speedy...
In recent years, there are many papers have discussed how to develop the digital campus and IT in education and most of universities of China have invested a large of money on it. After years of development, many people have been aware of the primary drawback in the development that is many universities focus on the hardware development, but ignore to develop software. Many universities on digital...
Mathematics as a subject has remained difficult and unpopular for most students. This is despite its importance in almost all careers, especially in the science and technological fields. This is partially due to the teaching methods employed by educators which place students in the spectator role. With the availability of the ever advancing and improving Information Communication Technologies, the...
