For patient well-being and also for cost efficiency, constantly improving the medical act is essential. All patients undergo a set of medical tests before going into surgery. In some cases, these tests have to be repeated in different hospitals due to the lack of a system that facilitates presenting and sharing patient's data. We present two e-Health solutions for hospitals and clinics in the medical data field. Our aim was to design and implement a unique system for medical data management. This system allows easy data transfer between medical facilities. It also improves the medical diagnostic and treatment process and it increases the quality of medical care. Also, it improves the communication between patients and physicians, decreases the duration and costs of hospitalization and improves the patient's quality of life. The second medical solution presented in this paper present the results of the medical tests directly to a screen in the operating room, further reducing the time a patient has to wait before going into surgery and also improving the medical act. Both medical solutions were tested in real-world scenarios with promising results.

The advances in Internet of Everything (IoE) and the market-oriented cloud computing have provided opportunities to resolve the challenges caused by the Internet of Things (IoT) infrastructure virtualization, capacity planning, data storage or complexity. The volume and types of IoT data motivate the need for a data storage framework towards the integration of both structured and unstructured data. In this paper, we propose a novel game theoretic technique for efficient and dynamic storage allocation in cloud-centric IoT systems. The benefit maximization problem is formulated as a cost-benefit analysis game investigating the storage capacity currently used in the cloud. In view of each player's strategy to lease additional storage capacity, the game property is analyzed and we prove that the game always admits a pure strategy Nash equilibrium. Since the player's decision affects the level of benefit maximization, we elaborate on a cost-optimal storage allocation incentive mechanism, which scales effectively once non-linear or linear demand for storage capacity occurs, towards achieving optimal leasing conditions on cloud storage and computing capacity level. The experimental validation tests prove the effectiveness of the proposed game theoretic approach allocating the requests for more storage capacity in a cost-effective manner, which achieves to maximize the benefits. © 2017 IFIP.

Because of the wide use of smartphones in our daily activities, a wide range of mobile applications have been developed to serve as assistive technologies. However, there is a lack of applications in the Arabic language to assist disabled people. The main aim of this paper is to build a simple yet accurate Arabic language application that is capable of helping blind users in real-Time. In the proposed technology, the blind user captures a photo and records his/her voice inquiry. The query is instantly sent with the captured photo to a set of volunteers. The volunteers answer the blind user enquiries and send the answers back. Fifteen visually impaired persons and ten volunteers were used in the experimental testing. The scenarios were carefully created based on realistic situations. The subjects were then asked to answer a questionnaire to test if their queries were answered effectively and efficiently. The early results are promising because all blind users found the proposed technology useful and 80% of them wanted to use it on a daily basis. In addition, all volunteers found the application easy to use with clear instructions and 80% of them were excited about using it to assist blind users.

Information retrieval from textual data focuses on the construction of vocabularies that contain weighted term tuples. Such vocabularies can then be exploited by various text analysis algorithms to extract new knowledge, e.g., top-k keywords, top-k documents, etc. Topk keywords are casually used for various purposes, are often computed on-the-fly, and thus must be efficiently computed. To compare competing weighting schemes and database implementations, benchmarking is customary. To the best of our knowledge, no benchmark currently addresses these problems. Hence, in this paper, we present a top-k keywords benchmark, T2K2, which features a real tweet dataset and queries with various complexities and selectivities. T2K2helps evaluate weighting schemes and database implementations in terms of computing performance. To illustrate T2K2's relevance and genericity, we show how to implement the TF-IDF and Okapi BM25 weighting schemes, on one hand, and relational and document-oriented database instantiations, on the other hand.

International Conference on engineering of Modern Electric Systems (EMES)

作者： Mircea Dulău Istvan Madaras Department of Electrical and Computer Engineering “Petru Maior” University Tîrgu-Mureş Romania Master at Automatic Systems of Industrial Process Control Faculty of Engineering “Petru Maior” University Tîrgu-Mureş Romania

The timber's drying process is a mandatory operation before any action of the wood processing. In the recent years, the fundamental research in the field of timber's drying has made progress, the physical laws regarding the removal of the water from the wood through different procedures (convection, vacuum, microwave etc.) being elucidated. The using of the calculus techniques allows the accurate simulation of heat and mass transfer phenomena, as well as of the mechanical aspects (internal stresses, deformations), which accompany the wood's drying process. The paper presents the implementation of the monitoring and the control system of the timber's conventional drying, using programmable controllers (Siemens), dedicated devices and dedicated software (Step 7).

There is need to replace the traditional materials used in mechanical constructions with cheaper materials characterized by high durability and simplicity of manufacturing. An alternative technology is 3D printing technology that uses ABS material (poly (acrylonitrile-co-butadiene-co-styrene)). 3D printing technology ensures the rapid change of model dimensions and shapes at the prototyping stage and a relatively cheap cost of new elements. There are many plastic materials producers on the market for a 3D printer. In this paper two of them have been choosen to a comparison and their mechanical parameters have been determined. The modal analysis of this material was carried out and the obtained values of resonance frequencies were compared.
