This study aims to examine the definition and attributes of artificial intelligence (AI) thinking support AI education, so educators can determine how such education should be conducted in grades K–12. The text mining method was using crawling co-word analysis design define Python programming language. cosine similarity word2vec techniques were used perform analysis. Cosine extracts paired word...

ABSTRACT ____________________________________________________________ This thesis investigates the prospect of using a Binary Discrete Cosine Transform as an integral component of an image compression system. The Discrete Cosine Transform (DCT) algorithm is well known and commonly used for image compression. Various compression techniques are actively being researched as they are attractive for...

Wavelet-based multiband dynamic range compression is developed to compensate for a common hearing impairment known as recruitment of loudness. The algorithm combines standard compression with intensity-level dependent gain calculation. Complexity and performance are similar to traditional techniques. Further, the methods established here can be applied to the more adaptive wavelet packets and l...

the head was large and firmly fixed, and being unable to put back the protruding arm by performing podalic version, I decided upon craniotomy as the best means of delivery. After administering a full dose of liquid extract of ergot, the patient was brought under the influence of chloroform, and craniotomy was performed. After emptying the cranium, a male foetus was delivered in a few minutes. T...

Many complex optimization problems in the real world can easily fall into local optimality and fail to find optimal solution, so more new techniques methods are needed solve such challenges. Metaheuristic algorithms have received a lot of attention recent years because their efficient performance simple structure. Sine Cosine Algorithm (SCA) is algorithm that based on two trigonometric function...

Colliding Bodies Optimization (CBO) is a population-based metaheuristic algorithm that complies physics laws of momentum and energy. Due to the stagnation susceptibility of CBO by premature convergence and falling into local optima, some meritorious methodologies based on Sine Cosine Algorithm and a mutation operator were considered to mitigate the shortcomings mentioned earlier. Sine Cosine Al...

Monitoring automotive exhaust gas aftertreatment components is required by law as part of the on-board diagnostics (OBD). For this purpose, a novel sensor device that determines directly the catalyst conversion could be used. It consists of a single, self-heated yttria stabilized ZrO2-based disc, separating two gas atmospheres. Two identical mixed-potential electrodes yield a voltage signal by ...

Powderous crystalline materials of the composition Fe3−xMnxC have been prepared by first synthesizing Fe3C via mechanical alloying in a planetary mill followed by the addition of elemental manganese and arc-plasma melting or via the classic ceramic route in an electric furnace. The milling time for the synthesis of Fe3C was significantly reduced through adjusting the parameters of the planetary...

This paper considered performance of content based image retrieval system using image representation nonparametric algorithms. Performance comparison of Epanechnikov, Gaussian and Histogram non-parametric algorithms was done in a generic image retrieval system. Chan & Vese and Cosine Angle Distance algorithms were used for segmentation and similarity matching respectively. The performance of th...
