Two leading paradigm shifts are taking place in teaching-learning today that are expected to have major and long-lasting impacts. The first one is the current environment and restrictions due to COVID-19 has driven academia to evaluate alternatives to traditional education. The leading option being deliberated and studied is a robust and effective...

Academia is adapting to the new age of online teaching and learning as the online mode has rapidly spread during the past several months. This is a significant paradigm shift and can also be viewed as an opportunity to think and experiment outside the box and question the traditional age-old ways of functioning in the onsite mode. As expected, ther...

With the rapid technology advances, there is an emerging consensus that the size and complexity of software designs are increasing so rapidly that they proportionally affect the magnitude of administrative and development efforts. An important consideration is how to estimate software complexity. This subject continues to be a research topic in the...

A rich and effective computational system must have a friendly user interface with appealing usability features that provides excellent user experience. In order to develop interactive systems with the best user experience, an innovative iterative approach to user interface engineering is required because it is one of the most challenging areas giv...

User interface engineering, critical to the development of stellar applications, is one of the most challenging areas given the diversity of knowledge, ideas, skills and innovations needed for building smart interfaces in order to succeed in today’s rapidly paced and tough, competitive marketplace. Many engineering aspects including graphical, anal...

There is an emerging consensus that the size and complexity of databases are increasing so rapidly that they proportionally impact the magnitude of administrative and development efforts. Consequently, these efforts and deployment resources can be managed only by adequately measuring and estimating database parameters. Organizations are often chall...

Language and communication are deeply conjugated with media in such a way that their phenomenal impact on every aspect of life can be revealed only if they are taken together as one synergistic whole. The principal objective of this paper is to examine approaching trends that characterize an emerging paradigm in language and communication. Evidence...

One of the challenges in software development is measuring and estimating software complexity at various levels of development. It is difficult to manage a software project without having well-developed measurement techniques. Traditionally, software complexity has often been measured by the lines of code or some vague aspects of the functionality...

Single walled carbon nanotubes (SWCNTs) are common transporters in medicinal chemistry science especially for drug delivery application. Therefore electrical properties of different kinds SWCNTs such as armchair (m,m), zigzag (0,n) and chiral (m,n) have studied in this research. For this aim; ab initio calculation method have employed for three arm...

Automata classes including Turing Machines, Pushdown Automata and Finite Automata define the most elegant models of computation in terms of set processors. This study elaborates pedagogically motivated intuitive and formal relations between mathematical models and other computer science areas, so that students can relate different areas of computer...

This paper presents one-stack automata as acceptors of context-free languages; these are equivalent to Pushdown Automata which are well known in automata theory. As equivalence relations such as equivalence of Turing Machines and two-stack Pushdown Automata help in learning general properties of formal modeling, the equivalence relation of Pushdown...

A theoretical ac impedance model of biological tissue has been proposed after studying a cellular membrane using X-ray diffraction technique [1], a metal/organic system using ac impedance spectroscopy [2] and reviewing two pieces of literature of similar topics [3, 4]. This paper emphasizes ac impedance techniques which can be used to study any het...

In Surface Mount Technology, the reliability and performance of electronic circuit boards is critically dependent on the quality of solder joints. The formation of a good solder joint is a function of both the solder paste flux and the metallic substrate to be soldered. It is highly desirable to have a means to evaluate a solder flux's ability to c...

Characterization of the nature of engineering materials is of primary importance to material scientists and engineers. Once the nature of a material is understood, models can be developed that allow the relationships that exist between composition and processing, and the properties and performance of materials to be defined. Impedance spectroscopy...

Browsing on the web, shopping online, sending messages, checking email, playing games, sending multimedia data, and paging are routine activities. Some of these activities are now possible through a mobile phone which has embedded itself in society faster than any communication system in history. Almost everyone agrees that the applications of wire...

Language processing systems are complex, costly and challenging requiring enormous computing power. This paper presents an embedded layered software architecture for lexical, syntactic, semantic, and pragmatic processing of a linguistic system. The software architecture is presented with components and their relationships along with an analysis of...

Solderability and processibility of soldering depend upon both the quality of the flux in a solder paste and the surface condition of the substrate of a printed circuit board. A means of monitoring solderability has been developed using both AC and DC electrical techniques. A physical model of solder paste has been developed from the results obtain...
