Image classification is the process of finding common features in images from various classes and applying them to categorize and label them. The main problem of the image classification process is the abundance of images, the high complexity of the data, and the shortage of labeled data, presenting the key obstacles in image classification. The cornerstone of image classification is evaluating the convolutional features retrieved from deep learning models and training them with machine learning classifiers. This study proposes a new approach of “hybrid learning” by combining deep learning with machine learning for image classification based on convolutional feature extraction using the VGG-16 deep learning model and seven class

The optimum trajectory of a single or multi-stage satellite launcher guided with proportional
navigation guidance (PNG) is addressed. The PNG is extended to compensate for the gravity effect.
For the trajectory optimization problem, the launcher is modeled as a mass point flying around the
center of the Earth. To provide a completely valid analysis, all known influences on the launcher
trajectory have been considered; Empirical equations have been used in order to model the Earth
standard atmosphere in SI units. A computer program had been constructed in order to simulate the
trajectory of such launcher from the available initial conditions. Pegasus launcher is used as a
hypothetical example. The simulator results

The question of word–formation motivation is one of the most urgent problems of morphological features of diminutive vocabulary in the languages of different structures, Arabic – Semitic and Russian - Slavic. The relevance of this question lies in the fact that the analysis of morphological elements of word-formation motivation plays an important role not only in identifying formal and semantic connections between different units of the same language, but also has an applied value in the comparative study of different languages. Taking in to account that word-formation motivation is usually considered sequentially in order to identify motivational relationships of this type of vocabulary, we will study motivation in comparative analy
