In this work the characterisation and modelling of the asynchronous impulsive (non-periodic) noise, which occurs in communication lines (PLC) when used as a communication channel, are performed. A strategy was implemented to detect the noise under different circumstances in a residential electrical environment. The study was conducted on purely linear loads. An implementation was adjusted with appropriate measuring devices and algorithms were designed to process the information recorded. The impulsive noises detected are Burst type, because they are the most critical noises that occur in a communication channel through power lines. Statistical processes are used to characterise and to model the noise. The Middleton model is used to determine its presence under certain conditions. The results are satisfactory. The Burst type non-periodic noise is detected. The results were perfect in relation to reality by applying the characterisation and modelling proposed.

The Internationalized Domain Name (IDN) homograph attack is a web security problem in which the attackers deceive the computer users about what websites they access by homologous domain names. Recently the growth of IDN homograph attack has become a severe problem with a significant probability of criminality like frauds for ordinary users. In this paper, we propose a classification method for IDN homograph detection by making use of Structural Similarity Index (SSIM). Compared to the existing approach, the experiment results showed that our improved classification method could increase the accuracy from 95.07% to 96.18% and decrease the false positive rate from 3.92% to 3.23%. We also conducted an empirical analysis of the IDN homograph data and training processes of the SSIM classification approach for discussion that our method takes advantages in homograph detection.

Inexperienced drivers always suffer from limited spatial information coming from side and review mirrors to complete parking tasks. The major obstacle is that they cannot easily estimate relative position of the parking space with respect to their vehicles. Therefore, this paper aims to develop a parking assistance display system that can continuously provide the top view of both the vehicle and the parking space for drivers. The system applies two wide-angle cameras mounted at the rear of the vehicle. In order to search for two farther corners of the parking space with efficiency, the FAST corner detection technique is employed. Three dimensional spatial coordinates of those corners can therefore be determined by the stereo vision framework. As a result, the position of the parking space relative to the vehicle can be estimated. To verify the effectiveness of the proposed parking assistance display, parking experiments with a golf cart were conducted. Experimental results demonstrate the parking tasks can be successfully accomplished with the help from the presented assistance display.

For an optimal fish raising under captivity conditions, biomass calculation is usually an essential factor to estimate the ideal amount of food required. Usually, this process implies human-animal interaction, however, fish manipulation can affect their correct growth or even cause their death. In particular, some fish species like Senegalese sole, can easily be stressed when they are manipulated out from their environment. The advances on image recognition systems have opened a new range of possibilities to avoid any kind of human-animal interaction. With a lowest estimation of 0.8 centimetres, and around 95% of accuracy detection, our novel prototype can successfully provide a highly accurate fish measuring estimation based on an image, which can be provided by any kind of device, such as mobile phone.

Non orthogonal multiple access (NOMA) can support massive accesses in 5G. Sparse code multiple access (SCMA) is a typical NOMA technology. Basic principle of SCMA is that multi-user bit data directly map into multi-dimensional complex sequences through the codebook. Grant-free SCMA allows users to select codebook from codebook pool to send data instantly, reducing the cost of overhead and delay of granting process. When the receiver and the sender use same codebook information, the data can be transmitted correctly. But in current SCMA researches, the problem of asymmetric codebook information between sender and receiver caused by the intrusion of codebook pool is not considered. In this paper, abnormal codebook detection is proposed in the grant-free SCMA. Because most of intrusion is unknown, detection is realised by comparing test codebooks with normal states. In this paper, without being focus on the whole normal codebook set, the process of detection is generated by extracting characteristics of normal codebooks. Tested objects in the process can include but not limit to codebook structure, constellations, relationship of constellations, overall feature of codebook pool. Detection can be executed step by step until discovering error state or accomplishing all steps to avoid facing high computational complexity caused by directly comparing with all normal codebooks. Besides, tested abnormal codebooks are saved and evolved to act as detectors. Future detection for unknown abnormal codebooks will do match with detectors which are evolved from those known abnormal codebooks.

The Hierarchical Temporal Memory Cortical Learning Algorithm is an algorithm inspired by the biological functioning of the neo-cortex, which combines spatial pattern recognition and temporal sequence learning. It organizes neurons in layered column-units built from many neurons connected in the more complex structure called regions (areas). Such hierarchically organized structures can also be connected in networks, which provides more cognitive capabilities like invariant representation. Complex topology and a high number of neurons in its structure require wide more compute power than a single machine with multicore processors and GPU. This paper aims to improve the HTM CLA by enabling it for horizontal scale on multiple nodes in a highly distributed system by using the Actor Programming Model. The proposed concept also makes use of existing cloud and serverless technology and it enables easy setup and operation of cortical algorithm in a distributed environment.The Proposed model is based on a mathematical theory and computation model, which targets massive concurrency. Using this model drives different reasoning about concurrent execution and should enable flexible distribution of cortical computation logic across multiple physical nodes. This work is the first one about parallel HTM Spatial Pooler on multiple nodes with named computational model.With the increasing popularity of cloud computing and serverless architecture, this work is the first step towards proposing interconnected independent HTM CLA units in an elastic cognitive network and can provide an alternative to deep neuronal networks, with theoretically unlimited scale in a distributed cloud environment. This paper specifically targets the redesign of a single Spatial Pooler unit.

Autism spectrum disorder (ASD) is a group of neurodevelopmental conditions in which the individuals face challenges with social engagement, age-appropriate pay and fail to develop appropriate peer relationship according to their developmental level. This study aims to evaluate, compare and rank the therapy techniques used in the management of ASD using the fuzzy preference ranking organization method for enrichment evaluation (PROMETHEE), a multi-criteria decision-making approach. Fuzzy PROMETHEE utilizes a pair-wise comparison of alternatives using preference function and weight. These parameters were prioritized based on their importance for the survivability of the patient. The techniques we selected are as follows: Applied behavioral analysis (ABA), cognitive behavioral therapy (CBT), speech therapy, and pharmacological therapy such as risperidone and aripiprazole. The result indicates that CBT is the most preferred technique, followed by ABA, aripiprazole, speech therapy, and risperidone. Nonetheless, new criteria and parameters could be considered and weights could be assigned based on the interests of the decision maker. We showed the applicability of the proposed technique in informing decision makers in choosing the right therapy technique for the management of ASD.
