A total of 107 radiomic features were extracted, including three groups of radiomic features such as morphological, first-order and texture. Relationships between the characteristics of each group were tested by Spearman’s correlation analysis. Differences between Grade II and Grade III tumour categories were analysed with Mann–Whitney U test. According to the results, it was seen that radiomic features can be used to differentiate the features of tumour levels evaluated in the same category.

There are different kinds of homo species but the most recent one with the most improved abilities are human beings of the present era, who have adapted themselves to the new technologies and life conditions by improving themselves. The substantial improvements in technology started with the French Revolution in 1799. Initially, technology helped human beings in the production and industry sectors. Thereafter, in the 1990s, technology penetrated living spaces, firstly helping with household duties and then impacting social life, first with the radio and later with the television. Living spaces started to change through the organisation of spaces, and most houses were organised according to location reserved for the television. This is the biggest change brought about by technology in living spaces. The expectations of human beings were on the rise simultaneously with economic welfare and consumption-based demands. In the 2000s, phyisical limitations occurred, while expectations increased even more. These were constraints over time, materials and economy, and the solution came from technology via virtual reality and generated cyber spaces, which were without limits, economical and surpassed the built environments. Due to the lack of physical conditions, built envionments ceded their place to virtual living spaces and virtual cities. In the present study, data collection was undertaken via a study of innovations within living spaces and also via an observation of social lives within living spaces. The present article aims to present what can be foreseen, on the basis of cause and effect, concerning the impacts of the current evolution on the one hand and massive outbreaks of viruses on the other hand, the impacts on the physical spaces of the homosapiens species that have succeeded in adapting to all the changes that they have come across from their beginnings until the present era, the impacts that both phenomena will have on the current living standards and living spaces of humans and what changes human living spaces will undergo in the ongoing process of evolution. Human beings will continue renewing themselves throughout the said phenomena before concluding their process of evolution. \u0000  \u0000Keywords: Innovative, technology, living spaces, living standards, homosapiens.","PeriodicalId":210768,"journal":{"name":"New Trends and Issues Proceedings on Advances in Pure and Applied Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127125061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although object classification does not necessarily have to be real time, object tracking is often intended to be carried out in real time. While the object tracking algorithm mainly focuses on robustness and accuracy, the speed of the algorithm may degrade significantly. Due to their parallelisable nature, the use of GPUs and other parallel programming tools are increasing in the object tracking applications. In this paper, we run experiments on the Efficient Convolution Operators object tracking algorithm, in order to detect its time-consuming parts, which are the bottlenecks of the algorithm, and investigate the possibility of GPU parallelisation of the bottlenecks to improve the speed of the algorithm.

First, we applied optimization algorithms on eight numerical benchmark functions which are sphere, axis parallel hyper-ellipsoid, Rosenbrock, Rastrigin, Schwefel, Griewank, sum of different powers and Ackley functions. After that, the training of ANFIS is carried out by mentioned optimization algorithms to predict the strength of heat-treated fine-drawn aluminium composite columns defeated by flexural bending.

Scheduling of time critical tasks is determined by estimating their worst-case execution times. To justify the model design of task scheduling, it is required to simulate and visualise the task execution and scheduling maps. This helps to figure out possible problems before deploying the schedule model to real hardware. The simulation tools which are used by companies in an industry perform scheduling simulation and visualisation of all time critical tasks to design and verify the model. All of them lack the capability of comparing simulation results versus real results to achieve the optimised scheduling design.
