The most important aims of mobile learning systems is providing relations between the real and virtual worlds and creating related instructing strategies with education activities in order to obtain appropriate educational achievements in addition to creating motivations in using mobile systems among the learning individuals. Offering potentials of instructing activities and places interested by individuals in this regard are among the most important aspects by which learners could increase their knowledge levels. In this respect and by describing the case, we offer a model in the form of a mobile learning recommender system, abbreviated by "PMLES". Hence in this article we try to improve the performance of recommender systems in mobile learning environments by presenting an integrated system and providing a mobile learning recommender system, and along with that offer a learning method appropriate with the level of knowledge among different learners. The aim for this proposing model is increasing the performance rate of recommender systems by considering the educational conditions and developments of each learner in intercity environments.

A reliable method for dehazing image and video was proposed. The goal is to achieve good dehazed images and videos with proper security at the receiver side. The image was dehazed by dark channel prior. The system based on fast single image dehazing and here the codecs used is joint photographic expert group. Then the compressed image is extended to compressed video, by using codecs H.264. Then by considering the dehazing effects before or after compression, the coding artifacts and motion estimation were investigated. Before compression produce better dehazing performance with fewer artifacts and better coding efficiency than after compression. By using these methods, the thickness of haze and haze free images and videos can be estimated directly. Then a watermark is added for digital right management and the watermarked image and videos is encrypted with a fast and reliable light weight algorithm. This image and video is transmitted to the receiver side. At the receiver side, the use with correct key can decrypt the image and the image will be watermarked with watermark symbol, the watermarked image can be used to trace illegal distribution. Thus this system produces a dehazed image and video with high secure and fast transmission.

In this paper, a novel scheme for efficient content-based medical image retrieval, formalized according to the Patterns for Next generation Database systems (PANDA) framework for pattern representation and management. This scheme involves block-based low-level feature extraction from images followed by the clustering of the feature space to form higher-level, semantically meaningful patterns. The clustering of the feature space is realized by an expectation–maximization algorithm that uses an iterative approach to automatically determine the number of clusters. Experiments were performed on a large set of reference radiographic images, using different kinds of features to encode the low-level image content. Through this experimentation, it is shown that the proposed scheme can be efficiently and effectively applied for medical image retrieval from large databases, providing unsupervised semantic interpretation of the results, which can be further extended by knowledge representation methodologies.

Induction motors being the major energy consumer in the plant offer opportunities of energy saving. In the spinning unit many induction motors are in-house rewound. This paper reports the analysis done on the rewound induction motors to determine its efficiency and life cycle cost comparison. Practical comparisons between rewound motors and the new motors are shown.

The storage of stable agro food such as corn and ogbono in developing countries like Nigeria is a great challenge due to high moisture content that causes deterioration at long period. However, dried agro food at certain temperatures could reduce this deterioration challenge and would extend storage life. In this study, the effect of temperature on drying rate and moisture content was carried out at 110o C, 120o C and 130o C on corn and ogbono, with the initial moisture content of (0.28 g). The moisture content decreased as time increases but tend to be constant with further increase in time. The minimum moisture content retained were (0.12 g, 0.11 g, and 0.1 g) for corn and (0.85 g, 0.83 g and 0.8 g) for ogbono at 110o C, 120o C and 130o C respectively. The drying rate at 130o C was higher compared to 120o C and 110o C but there was shrinkage and undesirable colour change observed. The characterization of the dried product using proximate analysis showed that drying at 110oC is more suitable for consumption both for the young and the elderly, with lower level of carbohydrate , corn (76.80) and ogbono (83.63) while protein, fiber and lipid levels of corn (9.94), (2.80), 3.78) and ogbono (5.40), (2.40), (2.17) respectively. Due to the favorable condition at 110oC, mineral analysis was also carried out, which showed trace elements of ogbono Ca (0.34), Mg (0.081), Na (0.025), K (0.25), P(0.15), Mn (0.068) and Fe (0.010) and corn; Ca (0.180), Mg (0.065), Na (0.017), (0.2), P (0.28), Mn (0.068) and Fe (0.002).

Bio-medical image de-noising and image enhancement are the two necessary and noticeable eras for better diagnosis and therefore the treatment within the medical field. Chromosomes images are ever found as blur images, so de-noising and image enhancement becomes essential extremely and area of interest for the researchers. Here the work of this analysis paper accommodates the chromosome image de-noising with the assistance of "Discrete Wavelet Transform (DWT)‟ families one by one and additionally the performances of different wavelet families are evaluated based on their Peak Signal to Noise Ratio (PSNR) and the value of Mean Square Error (MSE). After this, the three enormously efficient image improvement techniques are applied e.g. Contrast Adjustment (CA), Histogram Equalization (HE) & Adaptive Histogram Equalization (AHE) for the betterment of visualization. This single chromosome image could be a 2-D image. With the use of widely applicable "coif5‟Discrete Wavelet Transform, the chromosome image is decomposed up to the level 2, threshold and de-noised. Image enhancement is an important development to boost the visual impact of any image. All the simulation is performed with the help of the MATLAB R2010a platform.
