Lattice-based Sum Construction of Nullnorms on Bounded Lattices

Nullnorms on bounded lattices are generalizations of t-norms and t-conorms with a zero element laying anywhere in the underlying lattices. In this paper, new methods for constructing nullnorms on bounded lattices are proposed. The proposed construction methods are based on the lattice-based sum of lattices that has been recently introduced by El-Zekey et al. (see [9]), for building new (bounded) lattices from fixed ones indexed by a (finite) lattice-ordered index set. Subsequently, the new construction methods are applied for building several new families of nullnorms on bounded lattices. As a by-product, lattice-based sum constructions of t-norms and t-conorms on bounded lattices have been obtained. Furthermore, new idempotent nullnorms on bounded lattices have been also obtained.

Hybrid Classification in Bag of Visual Words Model

Classification of images by means of the BOVW method is well known and applied in different recognition projects, this method rely on three phases: detection and extraction of characteristics, representation of the image and finally the classification. SIFT, Kmeans and SVM is the most accepted combination. This article aims to demonstrate that this combination is not always the best choice for all types of datasets, different training sets of images were created from scratch and will be used for the bag of visual words model: the first phase of detection and extraction, SIFT will be used, later in the second phase a dictionary of words will be created through a clustering process using K-means, EM, K-means in combination with EM, finally, for classification it will be compared the algorithms of SVM, Gaussian NB, KNN, Decision Tree, Random Forest, Neural Network and AdaBoost in order to determine the performance and accuracy of every method.

Effect of Technology Distraction on Learning among Students in Higher Institutions in Central Nigeria

Technology distraction is the diversion of attention from a goal, which is majorly due to the utilization of technological devices during this period. Most students are unable to control their time. In ascertaining the effects and reasons for these distractions, a survey was done within two Nigerian institutions. This research showed that a large number of students utilize technology and the internet where most of the users who use laptops use it more for learning activities. With p-values of 0.152 and 0.012, findings showed that there is not enough evidence to show a relationship between age and the level of distraction and Sex and the level of distraction respectively. Distractions also occur through non-technical devices but with technical devices, distraction tends to be more with portable devices.

A Study on Modern Teaching Methodology of Secondary School for Student

In this paper, it shows concentrate on new showing technique of different student and teachers use for making a more successful line of study. Some other reasons, one of the biggest problem during student course is high failure rate in the various subject knowledge and twice the time student having needed to pass this course. This Phenomenon is reflected mainly to further graduation course during rapidly discourage before conventional classes. In the background as indicated by Federal Council of Engineering, in Brazil, the Engineers shortfall is assessed at 20,000 every year on a few territories of designing. There is finding the actual meaning of e-learning of given various researchers and what type of role e-learning in secondary school education relation with teaching and learning processes. In the current time, everyone is considering development and Educational Improvement. In this exploration paper advancement through E-learning in India is watched mostly in Secondary Schools. On the off chance that it arranged appropriately at that point, appropriate outcomes are influencing emphatically.

Social Commerce Acceptance of Students in a State University in the Philippines: A Unified View

One of the increasing concept nowadays in ecommerce is social commerce. Social commerce is the buying and selling of goods and services through the use of social networking sites. In addition, social commerce primarily affects the millennials composed mostly of college students. This study was conducted to determine the characteristics of students in terms of age and sex and their relationship to the factors affecting the acceptance of social commerce. The factors were based on the User Acceptance of Technology: Towards Unified View. Facebook was considered as the platform of social commerce in this study. The questionnaire was answered by 100 respondents composed of Bachelor of Science in Information Technology and Bachelor of Science in Business Management. Descriptive statistics was used such as frequency count, percentage and mean to determine the characteristics of the participants and factors affecting social commerce acceptance. Pearson correlation was used to find the relationship between the characteristics and factors affecting social commerce acceptance of students in a State University.

The Impact of using 3D Interactive Animation Tool in Teaching Computer Programming at the Senior High School Level

A quasi experiment with interview was adopted to study the aptness of using 3D animations as an instructional method to introduce programming concepts to students at the Senior High School level. This research work was conducted with 100 students of Akroso Senior High School in the Birim central municipality of the eastern region of Ghana who were generally programming novice. Programming concepts considered included programming environments, loops, functions sequential and conditional execution of programs. A paired t-test carried out on the results of the performance test presents a p-value of 0.008 indicative of a numerically significant difference between the mean marks of participants during the experiments that used 3D animation method as against the experiments that used the text base method. Results from the interview showed that the instructional method used had impact on the performance of the learners. The use of 3D animation method presented programming concepts in a form that the learners can understand, motivates them to pursue programming related courses at a higher level and also impacts positively on their performance.

Development of Pure Sine Wave Inversion System with Inbuilt Charging and Display Mechanisms

In recent years, Nigeria’s power generation output from all the available energy sources such as coal, natural gas, and water, is far from the expected number required to meet the energy demand of her teeming populace. This culminates in long hours of power outages frequently experienced in many parts of the country. However, there appears to be no end in sight to the problem. Alternatively, few citizens who can afford generator have wittingly resulted to the use of this device to supply power. Generator set has unavoidable disadvantages of high maintenance or running cost, noise pollution, and release of dangerous gases that pose danger to human lives. Evidently, that solution is risky and inadequate. Power inverter is an alternative and better means of generating electricity with little or no maintenance cost, environment or eco- friendly and poses no risk to human health. It is in that connection that we develop in this work 2KVA sine wave inversion system which produces sinusoidal A.C. signal required in homes for lightning and powering electronic gadgets like television, radio, refrigerator, Air conditioner etc. It is an improvement over square wave and modified sine wave inversion systems that generate digital approximations of A.C. signal. An interesting but new addition is the use of LCD display, interfaced with PIC16F688 microcontroller for showing the design specifications of the inverter.

Electromagnetic Characteristics of Yagi-Uda Antenna at HF/VHF/UHF

In this paper, the radiation characteristics of Yagi-Uda antenna operating at High Frequency (HF), Very High Frequency (VHF) and Ultra High Frequency (UHF) are examined. Upon employing method of moments, the current distribution on the antenna emerges from the solution of matrix equation. It is found that the angular distribution of electric field intensity generated in free space by the antenna, obtained by evaluating the integral of associated current distribution, is characterized by patterns with significant portion of radiation beam in the main lobe in the direction of Yagi axis. This is accompanied by relatively small undesirable radiation in the minor lobe, and which persist over those communication frequencies. It is observed also that the current distribution that generates the radiated electric field patterns is relatively consistent over the same range of frequency.

Users Knowledge on Awareness of Health Implications of Energy Emitted from ICT Devices

Humans are generally exposed to various sources of radiation in the course of our day-to-day activities irrespective of our work environment. Though these non-ionizing radiations from common sources like phones, computers, electronic devices, power lines and wireless devices are not known to present serious health risks, control remains the watchword. This study investigate the level of awareness of the health challenges posed by radiation from mobile phones, computers and other ICT devices among users and to suggest ways of reducing these free radicals from the body. A total of 500 students were used for the study with the aid of “Impact Awareness Questionnaire” developed and tested for face and content validity and a reliability test by internal consistency and stability assessments. The data captured in the study was tested using simple percentages, frequencies and Chi-Square. The result from this study establishes that there is no significant relationship between knowing that ICT devices radiate EMF and taking proactive measures to reduce the negative health effects. Though a vast majority of the respondents believe that radiation from their devices affects them health-wise, only a few are making efforts to reduce the effects.
