Over the past few decades, the major debate regarding healthcare throughout the world is the analysis, and findings of diseases by investigating the medical images. Musculoskeletal disorder classification from a massive radiological image archive has always been a tedious task for radiologists. In recent literature, deep learning paves its way towards biomedical image classification with maximum accuracy and efficiency. Besides, deep learning models have already outperformed in various medical applications. Specifically, Convolution Neural Network (CNN) and LSTM architecture have been widely used. In this paper, new variants of conventional deep learning models have been proposed. Subsequently, an exhaustive parametric comparison from the existing pre-trained model has been established to validate the improved efficacy and productivity.

In this paper, the main idea is to investigate the hypothesis that superlinear speedup occurs when the concurrent threads on General Purposes Graphic Processing Units (GPGPU) carry heavy workloads. In order to evaluate this hypothesis, Laplacian image edge detection algorithm with convolution filtering is chosen as a case study. In this work, local memories of GPGPU are utilized in order to achieve the superlinear speedup. The convolution filtering kernels of the Laplacian edge detection algorithm are invoked in these local memories. By this, the low latency of the GPGPGU local memory are deployed efficiently and this subsequently leads to a higher speedup. The results obtained presented that the superlinear speedup is achieved when the size of the convolution kernel is large. In this study, when the convolution kernel size is 7×7, superlinear speedup is observed for image dataset of sizes between 1KB-2500KB.

Financial statements as a tool for show the company financial performance and can be used as a basis for making economic decisions. Understanding of accounting standards specifically for SMEs can help SMEs in making business decisions. Information technology support and investment opportunity in SMEs are important factors that can help improve the financial performance of SMEs. Investment opportunity can be seen from the development of market tastes and reflection on the development of SMEs businesses. Investment opportunity is also obtained by innovating in production and marketing. The development of the SMEs business is in line with increasing business age. This shows the ability to survive batik business in facing the times and business competition. This study examines the factors that influence the financial performance of SMEs. using a sample of batik craftsmen. Data analysis was performed using multiple regression program which are currently widely used by researchers to test the research model that they formulate. The result of this research were (1) for small and medium-sized enterprises (SMEs), the company's age and investments opportunity greatly affect the company's financial performance. (2) IT support and good financial management in small and medium enterprises (SMEs) do not affect the company's financial performance.

This research is concerned with the use of development applications using mobile devices as a tool for blended learning models. However, in developing learning applications, one important concern is the user interface (UI). Therefore, the purpose of this research is to find out which UI design components are easy to use according to the user to be more user friendly, so that the purpose of using mobile applications for education can be realized. This study covers design principles that are appropriate for applications developed for platforms. Based on research, user interface testing has been carried out from 5 user interface principles and analysis using the System Usage Scale (SUS) given to 32 respondents. The results showed that the majority of respondents agreed that the mobile application developed had met the requirements of the user interface element.

Compressed Sensing theory promises to reconstruct the magnetic resonance images from partially sampled k-space data. Through this Compressed sensing - magnetic resonance imaging CS-MRI technique, we accelerate the reconstruction process but at the cost of high artifacts especially with the increase of high reduction factor and high reconstruction time. To minimize these artifacts, we proposed a segmented region based reconstruction technique to enhance the quality image without affecting much more the reconstruction time. In this algorithm, the partial k-space data segmented into two parts according to their frequencies. At central part which has lower frequency components selected and predicted by nuclear norm minimization. After that the part is fused with peripheral part of the k-space components and apply this recovery technique another time to reconstruct more accurate images in terms of conventional techniques. To analyze the performance of proposed algorithm, we compare the results for different data sets of brain with CS techniques. Better results in term of NMSE and time shows the effectiveness of proposed method with high reduction factor of data.

We explore a set of machine learning experiments in fine-grained emotion classification to test different proportion of positive and negative samples in the training data with the goal to examine if class imbalance affects classifier performance. The class distribution in a tweet corpus (EmoTweet-28) labelled with 28 emotion categories varies significantly with the largest category (happiness) occurring 11.5% and the smallest category occurring only 0.2%. For each emotion category, there are far more negative examples than positive examples. Unlike conventional wisdom, downsampling the data in our skewed corpus did not improve classifier performance. However, we found that increasing the negative examples in the training data leads to lower recall but higher precision. Demonstrating how the ratio of positive and negative examples in the training data affect the performance of emotion classifiers is the main contribution of this study.

In the World of Communication, digital transmission has its importance in sense of speed and accuracy which is the basic requirement of current time. Nowadays, successful as well as rapid communication is the main concern of the research. It can be achieved by using different technique and methods based on theories built upon the branches of applied sciences and engineering. In this research an algorithm is presented by sequentially combining two transforms, Wavelet and Krylov. The Algorithm was formerly developed by the same and was known as WK Algorithm. In this research the Algorithm is first studied for digital signal application and results are presented and concluded by applying also with other two methods in order to verify and validate the research.
