Pumping lemmas play an important role in formal language theory. Context-free languages (CFL) is the set of languages that can be defined by context-free grammars. Context-free grammars are used to define programming languages, natural language applications (such as grammar correctors), machine protocols and many others. The case studies are used to simplify the process analyses of the efficiency of pumping lemma for Context-Free Languages. To prove that a Language is Not Context-Free using pumping lemma for CFL, we created a guideline presented in the fourth section that contains a proposed algorithmic procedure. Pumping lemma for CFL is used to show the existence of non-context free languages. Insights and argumentations were provided in the end of the paper.

The contributions of the research study are development of a methodology perspective, mathematical model of estimation calculationand performance measurements with its analyses, insights and recommendations. The methodology includes applying different patterns, structural definitions and creating five-layered application that will follow the cyclomatic code analyses recommendations. Another contribution that the study tries to make is to become a good reference point for further researches in developing performance evaluation. Finally, the research results, insights and user evaluations have been stated and recommendations are provided.

Also, the assessment of whether it has any advantages over the traditional teaching methods in computer sciences. Assessment of learners on their attitudes, motivation, and effectiveness when using flipped classroom compared with traditional classroom has been realized. The research questions investigated are: "What kind of problems can we face when we have robotics classes in the traditional methods?", "If we applied flipped learning method, can we solve these problems?". In order to analyze all this, a case study experiment was realized and insights as well as recommendations are presented.

We used the original dataset from the National Institute of Diabetes, and Digestive and Kidney Diseases. The dataset can be used to predict whether or not a patient has diabetes, based on certain diagnostics. For analysis we used Amazon Web Services. We used AWS S3 service to store our dataset, and Amazon Sagemaker to perform an analysis. For the given dataset we applied three classification models: Logistic Regression Model, K-nearest Neighbors and Support Vector Machines. For each of the models we also performed a performance measurement. We also compared all the results we got and according to the results, Support Vector Machines has the best performance. Insights and recommendations are provided.

The development of mobile learning and its increasing penetration in education, poses new usability challenges and need for design of new types of human- device interactions. Concerning mobile learning as novel approach there is a lack of proposals and guidelines for designing usable mobile learning systems. The research study contribution is the proposed Framework of Usability guidelines for m-learning. The empirical study described here based on experimental case study is the basis for the devised 'usability framework' for m-learning and it can be of great value and help for practioners working in m-Learning.

The main research was focused towards creating an e-learning interactive mathematical system that will be used in the course "Discrete Mathematics" in learning mathematical operation of different types such as system of linear equations, matrices, determinants, functions etc. This gives the student learners additional advantages in learning and solving equations, and perform matrix operations in a shorter time and have a visual representation of it. It is also an opportunity for the student learners to gain computational experience and to check their results with the software ones. In order to assess e-learning effectiveness we have-proposed a methodology called ELUAT (E-learning Usability Attributes Testing) and as measuring instrument the PET (predefined evaluation tasks) inspection technique. It investigates the task-oriented learning approach and is modeled to support project based learning.

In this paper we propose priority based uplink scheduling scheme for IEEE 802.16 standard that improves the QoS performances of the WiMAX service classes, especially when the number of connections gets higher. Essential QoS parameters like throughput, delay and jitter have been calculated using the ns-2 simulation tool and changing the number of the ertPS connections. Obtained results prove that our proposed uplink scheduling algorithm gives better results compared with so far known uplink scheduling mechanism.

The aim of the realised experiment was to analyze, compare and measure the efficiency of algorithms for searching, insertion and deletion in a list of elements. An experimental case study is done through implementing the list as: 1) Array Data Structure and as 2) Dynamic Linked List Data Structure and measuring the performance. The contribution of the study is based on the realized experimental case study analyses, its insights and recommendations for improving the efficiency of algorithms for searching, insertion and deletion in a list of elements. The recommendations, and insights gained from the realized measurements are presented and discussed.

These improvements were obtained by occurrence coding connected t DBGrid. The accomplishment of these functions is regulated by the way that users of Windows applications accepted it as usual in that businesses, so the regulations of these applications which are programmed in Delphi improved its quality. Very important attribute of this paper is that the coding of algorithms have been done for using its procedures without a change, what creates the modularity of the source code.

This study systematically tested the correlation between critical activities and critical paths and risk scenario case management applied in project planning since its early beginning up to end. Risk management is critical to success in complex projects but is seldom applied effectively and its integration within software life cycle is missing. Based on the literature review discovered a high rate of ICT projects failure. What were the causes of these expensive and seemingly uncontrollable failures of ICT projects? Despite the review of considerable published literature on the risk management for ICT software projects and their frequent failure did not discover a satisfactory Risk Management framework and model specific to ICT software projects. In order to investigate these issues a research study was realized and as contribution a MARUNA risk management model was created. I...

The focus of this research study was the invesitagation of multicollinearity of m-learning and e-learning factors. The investigation also tested the correlation between the variables that served as indicators for analyses of multicollinearity. After the data was colected and analysed used regression equations to measure the statistical significance of the data obtained and their relationship. Tested the level that the regression equation predicted the multicolinearity. Findings are presented and recommendations are provided.
