Voltage Sag Enhancement By DVR Based On PQ Theory Using LabView
No full textThe voltage sag condition in the power system has a direct effect on the quality of the power system quality. Voltage sag has a major effect on sensitive-voltage loads, causing a high inrush current, failure in the system, and price loss.The Dynamic Voltage Restorer (DVR) is regarded as one of the effective methods for controlling voltage in a power system. This paper describes the DVR control unit based on PQ theory to enhance the quality of the power system. The suggested control technique utilizes 3-phase compensation modules, based on the desired Sag condition. Also, this paper used LabView software to simulate the DVR for voltage variation in a power system

Extraordinary Patent License
No full textMoral rights represent a middle stage between personal rights and rights in rem, as they take some of the characteristics of these and those, and can not be considered absolutely within any of these groups, and these rights constitute a group of elements represented by innovations and other industrial and commercial rights, such as patents, industrial models and marks What separates these rights and rights in kind is that they do not remain monopolized by their owner throughout the period of legal protection assigned to them. Rather, the essence of these rights is to benefit others from them despite the fact that their ownership remains at the disposal of the owner, as the law imposes on the owner of the patent to grant the license to others. By benefiting from the invention within a certain period of granting the patent for the purpose of the public interest. If he refuses to license with consent, the legislator intervenes by granting a license against his will and with the knowledge of the public authority in order to achieve the interest of the group, all without prejudice to the rights of the patent owner in terms of ownership and in return for that license within a certain period of time Under the so-called exceptional license patent.
Future visions for the development of the Distance education system in light of Epidemic"Covid-19 as a model
Get PDFThe information explosion and the tremendous development in the means of communication today have put the educational and knowledge environment in front of great developments and a high speed of performance, with distinctive uses of very diverse electronic technologies. This required radical changes in the quality of education and the roles of students; That is, moving them from classical learning to electronic learning, so there was a need to use this type of education as an effective strategy in higher education aimed at improving the educational process, and working to promote and value scientific research at the university level. In light of the exceptional circumstances imposed by crises, the latest of which is the Corona pandemic, it has become necessary to use e-education as an effective strategy to advance scientific research and ensure its continuation. Therefore, we will seek in this paper to clarify the importance of distance education at the university level and to highlight its role in activating modern technologies in light of the challenges and obstacles in a time of epidemic
Incidence of Hashimoto's thyroiditis and its relationship to age, sex, smoking and blood groups.
Get PDFThis study was aimed to demonstrate the incidence of Hashimoto's disease in Iraqi patients and its correlation to some of the sociodemographic features. The research groups involved (50 patients with Hashimoto?s disease and 50 healthy subjects). All of them were subjected to the estimation of levels of free triiodothyronine (FT3), free thyroxine (FT4), TSH, anti-thyroid peroxidase (anti-TPO), and anti-thyroglobulin (anti-Tg). The results demonstrated that there is a dramatic increase in the occurrence of HT in older patients. The age group (41-50 years old) was the most age group affected by Hashimoto's disease, followed by the age groups (31-40, 21-30, and 9-20 years old) respectively. A significant proportional correlation (R:0.952, P:0.024) was found between HT disease and aging. According to the gender, the results found that the vast majority (82%) of patients were females (P = 0.01). Also, the smoking percent was (40%) of patients. The presence of autoimmune thyroid disease in one or more individuals within the family (family history) was also evaluated and the results found that (28%) of the Hashimoto?s disease group have a positive family history of thyroid autoimmune diseases. It can be concluded from these results that females are more prone to developing Hashimoto?s disease compared to males, in other words, the female gender is a risk factor for the occurrence of autoimmune hypothyroidism. Also, the negative impact of smoking and family history gives an indication that these parameters are independent and don’t associate with Hashimoto?s disease at least in the current study
