In this paper, we propose a bio-inspired Fuzzy Lévy Taxis algorithm to solve the robotic odor source localization problem in dynamic odor plumes. According to the proposed algorithm, the robot is programmed to move for a length with a turning angle at each step until reaching the odor source. The movement length and the turning angle follow two specific probability distribution, of which the parameters are adaptive through a fuzzy logic system. The proposed algorithm was compared with the Adaptive Lévy Taxis algorithm in simulated pseudo-Gaussian plumes. Our proposed algorithm shows a higher success rate and efficiency. The algorithm has also been systematically evaluated in simulated filament-based odor plumes under various environmental conditions. The results revealed that the performance of the proposed algorithm is consistently good in various environmental conditions in terms of success rate, number of steps and distance overhead to find the odor source.

Russian language is ranked as the sixth most spoken language in the world. It shows a high interest in the world population to use and learn the language. The Russian language has different alphabets from the Indonesian language, which is called Cyrillic. It has a different shape from the alphabet in general, which makes some obstacles to learn, understand and pronounce it.. Currently, technology is growing fast, and it changed people's lifestyles to be more practical and mobile so that the smartphone becomes one of the society's needs. Android is one of the most used operating systems in a smartphone nowadays, so the Capture to Translate was built in android-based. Capture to Translate is a media which is designed as a solution for those problems. The system was made based on imageprocessing, the feature extraction process, and artificial intelligence using Random Forest algorithm classification with interface Android mobile application that utilizes the camera as an input device. This system has the highest accuracy of 93.33% at one syllable, 85% at two syllables, and 84.76 % in 3 syllables.

Manycore architectures are mainly composed of a very large amount of computing nodes interconnected with a multiplicity of links usually forming a NoC-like mesh architecture. High-speed links permit to obtain a higher throughput but are much more expensive than normal links, making the interconnection of the system a cost/performance trade-off. Simulating such architectures is very important in order to characterise the optimal network topology for a given problem. In this work we introduce SCALPsim: a simulation framework permitting to evaluate routing algorithms and network properties in 1-D, 2-D and 3-D regular mesh topologies simultaneously using links of different characteristics in terms of latency and throughput. These features are particularly interesting in large scale systems with processing elements grouped into clusters, where communication properties differ largely inside and between clusters. This paper presents the framework and an application based on Cellular Self-Organizing Maps - CSOM.

In this paper a method for estimating mean opinion score for noisy images is presented. The focus is to create a robust method, which is not suited to the single image database. Algorithm is validated using three different databases, which shows that it is more generic than other methods. Moreover, proposed solution works as non-reference image quality assessment algorithm, which means that only distorted image is used for evaluation. Results obtained with proposed method are compared with two other algorithms designed for non-reference IQA.

Referenceless or Blind image Deblurring (BID) is a challenging task in image restoration, because of the absence of previous information about the blurring process. In BID, the Point Spread Function (PSF) that causes blur is unknown and finding it is a challenging task to do. In contrast, reference-based image deblurring techniques are better in terms of achieving deblurred images, as in such cases we know the cause of blur and many filters and methods get the job done easily. In real life imaging, the presence of blur is caused due to many reasons including motion, defocus, atmospheric turbulence and noise in capturing device. Removing such blur to produce sharp images is very important in many cases as of today's technological driven era demands for images of unspoiled quality. This paper presents a method to eliminate blur in the fastest way. The scheme is devised to use a Genetic Algorithm (GA) on Google Colab to find PSF of the blur kernel. This work tries to estimate the parameters of blurring using quality score minimizing. Once the PSF is estimated, the Wiener filter is used for deblurring in Google Colab. This scheme presents the implementation of the algorithm on Google Colab to use GPU for achieving parallelism and reduce implementation time. Validation of the work has been carried out on different images and the system achieved marked improvements over existing approaches. The work presented is simple and efficient which requires no former information about the original sharp image or deblurring process.

This paper addresses the problem of estimating the location and size of a wildfire, within the frame of a semi-autonomous recon and data analytics quadcopter. We approach this problem by developing three different algorithms, in order to accommodate this problem. Two of these taking into the account that the middle of the camera's FOV is horizontal with respect to the drone it is mounted. The third algorithm relates to the bottom point of the FOV, directly under the drone in 3D space. The evaluation shows that having the pixels correlate to ratios in percentages rather than predetermined values, with respect to the edges of the fire, will result in better performance and higher accuracy. Placing the monocular camera horizontally in relation to the drone will provide an accuracy of 68.20%, while mounting the camera with an angle, will deliver an accuracy of 60.76%.

Currently, the demand for automated technology is increasing rapidly. People are trying to find sources that make their work easier, errorless and fast. One such recent trend in technology that aims to aid people in this purpose, is the automated robotic technology. An autonomous robot can perceive changes in its environment, make decisions based on how it has been programmed to recognize these changes and then actuates a predefined movement. In this paper, one such application of autonomous robots for plant leaf disease detection has been presented. The conventional method for detection of leaf diseases is through naked eye observation, which is highly unreliable and inaccurate. The proposed project deals with the development of an automated voice controlled robotic car built extensively using the micro controller and image sensor network that helps in detecting the leaf diseases affecting a plant (like basil, which is considered in this paper) within a garden. Upon detection of the disease, using imageprocessing, the system alerts the user about the prevalent leaf diseases in the plant along with a set of measures to counter them. One of the major advantage of this system is that, it uniquely integrates the mobility of the robot in rough terrain with the simple K clustering and SVM algorithm for accurate detection of the leaf disease without much human intervention. The overall impact would be a user friendly voice automated robotic vehicle which eases the process of plant leaf disease detection.

Currently the availability of medical images data itself is not a challenge, but the acquisition of relevant annotations/labelling for these images is. An unsolved challenge in medical image analysis and its related radiology reports is to turn the radiology reports into an accurate annotations or structured labels in an automated manner using Natural Language processing (NLP). Traditional rule-based Machine Learning (ML) and Deep Learning (DL) algorithms are two approaches which were used in the extraction and annotation of radiology text reports. This paper provides a comparison of the performance of traditional rule-based machine learning to that of using deep learning algorithms in the extraction and annotation of radiology text reports using natural language processing (NLP). It presents an accurate analysis of the two discussed approaches and supports such with critical evidence related to the effects both approaches have on the issue of radiological reporting. According to the evaluation of the obtained data, the research concludes that Deep Learning (DL) models perform with higher efficiency than both the TML and validated NLP classifiers in terms of accuracy in extracting the required text information from the free-text radiology reports.
