Opis:
With the changing technology, humanity has reached Industry 4.0 starting from the steam engine. With these developments, human resources in the organisations need to store and process data. A new application that enables digital human resources to easily access its data is cloud computing. The aim of this article is analyse how cloud technologies affect human resources management in Turkey. A descriptive method was used in this paper to explain the concept of digitalism in the discussed area and analyse the relationship between cloud system and digital human resources management. Data was drawn from the scientific and professional literature documents on this subject. Many organisations do not have enough knowledge about cloud computing in Turkey. There are also concerns about cloud systems security and economic equilibrium of companies. It is predicted that companies that adopt this technology will have a more efficient and comfortable human resources process and become more prosperous. Organisations should work for the development of human resources management system by digitising it. Organisations whose number of employees is increasing day by day, face problems, but they can handle this situation through the careful implementation of cloud computing. Cloud systems provide organisations with benefits such as storage capacity and easy access to data anytime and anywhere.

Opis:
Radioactive aerosols in the confined workplace are a major source of internal exposure hazards for workers. Cloud-type radioactive aerosol elimination system (CRAES) have great potential for radioactive aerosol capture due to their high adsorption capacity, lack of cartridges and less secondary contamination. A CRAES was designed and constructed, and a FeOOH/rGO composite was directly prepared by a hydro-thermal method to characterise and analyse its morphology, chemical structure and removal efficiency for simulated radioactive aerosols. The results show that the FeOOH/rGO composite works in synergy with the CRAES to effectively improve the removal efficiency of simulated radioactive aerosols. A 30-minute simulated radioactive aerosol removal rate of 94.52% was achieved when using the experimentally optimized composite inhibitor amount of 2 mg/L FeOOH/rGO with 0.2 g/L PVA as a surfactant. Therefore, the CRAES coupled with the composite inhibitor FeOOH/rGO has broad application potential for the synergistic treatment of radioactive aerosols.

Opis:
In this paper, description of a concept of cloud storage is offered. Cloud data storage is a model of an online storage where the data is being stored in multiple, divided between network servers that are provided for clients’ usage, mostly by a third-party company. The majority of the cloud storages (as opposed to file-exchangers) are offering almost boundless set of functions for free, by only limiting the size of the available storage (mostly a couple of gigabytes). Integrated data mining is being used for extracting potentially useful information from unprocessed data. The methods of data analysis are quite important with cloud computing. The implementation of the methods of integrated data mining inside the cloud will let the users receive the helpful information from non-structured or half-constructed web data sources. The main purpose of this work is to organize huge diverse data coming from different sources into clusters, depending on the type of data.

Opis:
Cavitation is one of the most interesting phenomena in area of fluid flow research. It can be observed in many different hydraulic systems and its effects can be very serious. Basic problem with cavitation is its observation. The main aim of the paper is to propose and evaluate the simple method allowing registration of the cavitation cloud shape, which will be financially and computationally undemanding. Therefore, the article presents the system registering the shape of cavitation cloud. It is based on the optoelectronic devices, i.e. lasers and photoresistors, as well as on the assumption that cavitation leads to diffusion of lasers light on the vapor bubbles. The experiment was performed for three cavitation inducers and two flow velocities. Obtained results shows that the shape of cavitation cloud is dependent on the inducer, but not on flow velocity. It can be concluded that the described optoelectronic system can be regarded as an inexpensive alternative to traditional methods of cavitation observation.

Implementation
Opis:
The Internet has evolved from connecting people and later videos, photos, and text to more recently physical objects. Using sensors, physical objects can “talk” (transmit data) to each other and even command each other to perform a physical act. As things and people become more connected, such objects will also become part of social net-works, much in the same way that people tag photos on Facebook. In this way, the value of such objects will increase for both research and learning. The IOT and Cloud computing technologies can provide solutions for the above-mentioned problems in the education system. Cloud computing enables users to control and access data via the Internet. The main users of a typical higher education cloud include students, faculty, administrative staff, Examination Branch and Admission Branch. All the main users of the institution are connected to the cloud. Separate login is provided for all the users for their respective work[12]. Teachers can upload their class Tutorials, assignments, and tests on the cloud server which students will be able to access all the teaching material provided by the teachers via the Internet using computers and other electronic devices both at home and college and 24X7. This paper focuses on the integration of Cloud and IOT for the education system. Connected de-vices can help make life easier for students with special needs. Many of the daydreams for IOT in education involve students taking advantage of new technologies to complete cool new projects.

Opis:
Cloud computing is a growing field since data storage is becoming ever more decentralized. Providers of Cloud solutions want to insure the safety and availability of their customers’ data. In order to increase these performance indices, several storage policies have been implemented: replication, erasure codes, etc. A few of them rely on randomized procedures. In this paper, we focus on the influence of a specific storage policy on the availability of a given file. Taking only disk failures into account, we provide a general formula for the average file unavailability U ̅, which is a generalization of the well-known k-out-of-n problem, to which it reduces when disks are identical. We then calculate U ̅ for several configurations when disks have different reliabilities, and show that the disk arrangement has a major impact on the result. We also provide an approximation which could be helpful for more complex arrangements.

Opis:
Recommender systems (RS) have emerged as a means of providing relevant content to users, whether in social networking, health, education, or elections. Furthermore, with the rapid development of cloud computing, Big Data, and the Internet of Things (IoT), the component of all this is that elections are controlled by open and accountable, neutral, and autonomous election management bodies. The use of technology in voting procedures can make them faster, more efficient, and less susceptible to security breaches. Technology can ensure the security of every vote, better and faster automatic counting and tallying, and much greater accuracy. The election data were combined by different websites and applications. In addition, it was interpreted using many recommendation algorithms such as Machine Learning Algorithms, Vector Representation Algorithms, Latent Factor Model Algorithms, and Neighbourhood Methods and shared with the election management bodies to provide appropriate recommendations. In this paper, we conduct a comparative study of the algorithms applied in the recommendations of Big Data architectures. The results show us that the K-NN model works best with an accuracy of 96%. In addition, we provided the best recommendation system is the hybrid recommendation combined by content-based filtering and collaborative filtering uses similarities between users and items.

Opis:
In this paper, we propose a distributed system for point cloud processing and transferring them via computer network regarding to effectiveness-related requirements. We discuss the comparison of point cloud filters focusing on their usage for streaming optimization. For the filtering step of the stream pipeline processing we evaluate four filters: Voxel Grid, Radial Outliner Remover, Statistical Outlier Removal and Pass Through. For each of the filters we perform a series of tests for evaluating the impact on the point cloud size and transmitting frequency (analysed for various fps ratio). We present results of the optimization process used for point cloud consolidation in a distributed environment. We describe the processing of the point clouds before and after the transmission. Pre- and post-processing allow the user to send the cloud via network without any delays. The proposed pre-processing compression of the cloud and the post-processing reconstruction of it are focused on assuring that the end-user application obtains the cloud with a given precision.
