Intelligent Microclimate Control System Based on IoT
Aigerim Bakatkaliyevna Altayev,Batyrkhan Sultanovich Omarov,Young Im Cho 한국지능시스템학회 2016 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.16 No.4
The present research paper is devoted to solving an urgent problem, i.e., the energy saving and energy efficiency of buildings. A rapid settlement method and experimental control of the energy conservation based on the specific characteristics of the thermal energy consumption for the heating and ventilation of the buildings, and as well as the rapid development of wireless sensor networks, can be used in a variety of monitoring parameters in our daily lives. Today’s world has become quite advanced with smart appliances and devices such as laptops, tablets, TVs, and smartphones with various functions, and their use has increased significantly in our day-to-day lives. In this case, the most important role is played by a wireless sensor network with its development and use in heterogeneous areas and in several different contexts. The fields of home automation, process management, and health management systems make extensive use of wireless sensor networks. In this paper, we explore the main factors of the microclimate in an indoor environment. We control the temperature humidity, and other factors remotely using sensors and Internet-of-Things technologies.

Heterogeneous cellular networks are gaining momentum in industry and the research community, and are attracting the attention of standard bodies such as 3GPP LTE and IEEE 802.16j, whose objectives are to increase the capacity and coverage of cellular networks. In this article, we provide an overview of expansion strategies, optimal locations of base stations with different characteristics, and radio-planning models.

In modern conditions, the functioning and management of electric power systems requires the creation of a computational model for large-scale schemes based on methods for estimating the state. Such schemes are not fully observable, data may be distorted, their synchronization is poor and, as a consequence, the adoption of incorrect decisions based on the calculation model. At present, the agent approach is not applied to the development of systems aimed at solving problems in the field of electric power industry and assessing the states of electric power systems in particular. The proposed approach to the development of multi-agent systems should enable the interaction of agents created on different software platforms, create new ones and edit existing algorithms in the system through agent scenarios. An approach to creating multi-agent systems for estimating the states of electric power systems with the possibility of cross-platform interactions and agent scenarios is developed. The proposed approach was tested on a test system, and at the moment a system is being developed for assessing the state of electric power systems.
Weighted Hardy inequalities with sharp constants
Aigerim Kalybay,Ryskul Oinarov 대한수학회 2020 대한수학회지 Vol.57 No.3
In the paper, we establish the validity of the weighted discrete and integral Hardy inequalities with periodic weights and find the best possible constants in these inequalities. In addition, by applying the established discrete Hardy inequality to a certain second--order difference equation, we discuss some oscillation and nonoscillation results.

Aims: The role of mTOR inhibitors, such as EVL, has not been established for pediatric liver transplant recipients up to now, although data from adult solid organ graft transplantation are very promising. Major complications following pediatric liver transplantation in the long-term course include chronic graft rejection and CNI-derived nephrotoxicity. Methods: The purpose of our study was to report first results using EVL as a rescue therapy in pediatric liver transplant recipients for the following indications: chronic graft dysfunction n=12, suspected CNI toxicity n=3, hepatoblastoma n=2, and recurrence of primary sclerosing cholangitis post-Ltx n=1. Results: Four patients with chronic graft dysfunction developed completely normal liver function tests using EVL, six patients showed partial improvement, and two patients did not respond at all. One patient with CNI-induced nephropathy showed a slightly improved GFR. Both patients with hepatoblastoma did not develop any metastasis post-Ltx. First experience with EVL in pediatric liver transplant recipients shows promising results in patients with chronic graft failure when standard immunosuppression has failed. Conclusions: The future role of EVL in immunosuppressive protocols for children post-Ltx has to be proven by controlled clinical trials.
