This article analysis the current situation of the virtual construction in university, which information non-sharing, poor safety and difficult management. Aiming at data diversification and the difference between platform, develop tools and system, making every network teaching resources system as an “information islet”, thus cause the disperse and independence of resources and data, integrate each resources system effectively by looking for a service governance structure. We proposed management system and method for private universities of long-term development. The main research is to set up the unified authentication system which can complete unified authentication and authority and administer. Using the virtual server technology, Information Office will set up a virtual campus portal platform with unified planning and concentration deployment, which is simple operation, advanced technology, safe and reliable, to realize unified management and guarantee the information resources interoperability and consistency.

Throughout the history, teachers have played a crucial and missionary role in the preparation of generations as citizens of the future. Gratitude on teachers is definitely a patriotic obligation to them.In Albania, due to different historical, geographical and economic factors, teachers have worked and lived in difficult conditions. This is not only in the long periods of foreign conquests and in the period of the National Renaissance but also after the victory of Independence and the creation of an independent Albanian state.Most of them, as true missionaries, regardless of the conditions, devoted themselves to that noble silence, worked without a self-propelled for the nation, which always required renaissance. With and without appropriate school facilities, with difficult general conditions, with or without texts, with a lack of teaching resources, without guaranteed livelihoods, served in an exemplary manner to teach new generations the writing of Albanian language and to cultivate to the student knowledge and how to love their country.But when does the formation of teachers in Albania have the most significant institutional beginnings or developments?Through this paper I tried to bring into attention the decisions of the Congress of Elbasan in 1909 as the first Albanian Pedagogical Congress whose primary task was the opening of a Pedagogical School. This school would served in the institutionally studied preparation of teachers whose job at that time was a national emergency for the development of the Albanian nation. This school was set up to open in the city of Elbasan.Elbasan, a city of Middle Albania, has been described as the cradle of the Normal School. Alongside the economic and social development, Elbasan was also acclaimed for his cultural and educational development, especially in the period of the National Renaissance.Of great importance in the formation of students there is the patriotic spirit of the Renaissance, which was always alive and powerful among Normale's teachers.Patriotic education of students remained as primary target in the field of general formation. Albania's Albanian language (literature, history, and geography) was developed at the highest possible level of time. Since its beginning, Normal School was not seen simply as a high school, but as an educational institution that represented the dignity of the nation, which would radiate the light of Albanian knowledge. Opening Normale School was not a matter of knowledge but also patriotism.

Current design manuals provide guidance on how to design exit ramps to facilitate driving operations and minimize the incidence of crashes. They also suggest that interchanges should be built along straight roadway sections. These criteria may prove ineffective in situations where there is no alternative to terminals being located along curved motorway segments. The paper investigates driving behavior along parallel deceleration curved terminals, with attention paid to the difference in impact between terminals having a curvature which is the same sign as the motorway segment (i.e., continue design), and those having an opposite curvature (i.e., reverse design). A driving simulation study was set up to collect longitudinal and transversal driver behavioral data in response to experimental factor variations. Forty-eight drivers were stratified on the basis of age and gender, and asked to drive along three randomly assigned circuits with off-ramps obtained by combining experimental factors such as motorway mainline curve radius (2 values), terminal length (3), curve direction (2), and traffic conditions (2). The motorway radius was found to be significant for drivers’ preferred speed when approaching the terminal. Terminal length and traffic volume do not have a significant impact on either longitudinal or transversal driver outputs. However, the effect of curve direction was found to be significant, notably for reverse terminals which do not compel drivers to select appropriate speeds and lane change positions. This terminal type can give rise to critical driving situations that should be considered at the design stage to facilitate the adoption of appropriate safety countermeasures.

With the advent of 5G verticals and the Internet of Things paradigm, Edge Computing has emerged as the most dominant service delivery architecture, placing augmented computing resources in the proximity of end users. The resource orchestration of edge clouds relies on the concept of network slicing, which provides logically isolated computing and network resources. However, though there is significant progress on the automation of the resource orchestration within a single cloud or edge cloud datacenter, the orchestration of multi-domain infrastructure or multi-administrative domain is still an open challenge. Towards exploiting the network service marketplace at its full capacity, while being aligned with ETSI Network Function Virtualization architecture, this article proposes a novel Blockchain-based service orchestrator that leverages the automation capabilities of smart contracts to establish cross-service communication between network slices of different tenants. In particular, we introduce a multi-tier architecture of a Blockchain-based network marketplace, and design the lifecycle of the cross-service orchestration. For the evaluation of the proposed approach, we set up cross-service communication in an edge cloud and we demonstrate that the orchestration overhead is less than other cross-service solutions.

The authors have been investigating the various characteristics of screw-type centrifugal pumps, such as pressure fluctuations in impellers, flow patterns in volute casings, and pump performance in air-water two-phase flow conditions. During these investigations, numerical results of our investigations made it clear that three back flow regions existed in this type of pump. Among these, the back flow from the volute casing toward the impeller outlet was the most influential on the pump performance. Thus the most important factor to achieve higher pump performance was to reduce the influence of this back flow. One simple method was proposed to obtain the restraint of back flow and so as to improve the pump performance. This method was to set up a ringlike wall at the suction cover casing between the impeller outlet and the volute casing. Its effects on the flow pattern and the pump performance have been discussed and clarified to compare the calculated results with experimental results done under two conditions, namely, one with and one without this ring-type wall. The influence of wall’s height on the pump head was investigated by numerical simulations. In addition, the difference due to the wall’s effect was clarified to compare its effects on two kinds of volute casing. From the results obtained it can be said that restraining the back flow of such pumps was very important to achieve higher pump performance. Furthermore, another method was suggested to restrain back flow effectively. This method was to attach a wall at the trailing edge of impeller. This method was very useful for avoiding the congestion of solids because this wall was smaller than that used in the first method. The influence of these factors on the pump performance was also discussed by comparing simulated calculations with actual experiments.

Objectives:Pediatric cardiology has an expanding role in fetal and pediatric screening. The aims of this study were to observe how district hospitals use a pediatric telecardiology service, and to compare the costs and outcomes of patients referred to specialists by means of this service or conventionally.Methods:A telemedicine service was set up between a pediatric cardiac center in London and four district hospitals for referrals of second trimester women, newborn babies, and older children. Clinicians in each hospital decided on the role for their service. Clinical events were audited prospectively and costed, and patient surveys were conducted.Results:The hospitals differed in their selection of patient groups for the service. In all, 117 telemedicine patients were compared with 387 patients seen in London or in outreach clinics. Patients selected for telemedicine were generally healthier. For all patients, the mean cost for the initial consultation was £411 for tele-referrals and £277 for conventional referrals, a nonsignificant difference. Teleconsultations for women and children were significantly more expensive because of technology costs, whereas for babies, ambulance transfers were much more costly. After 6-months follow-up, the difference between referral methods for all patients was nonsignificant (telemedicine, £3,350; conventional referrals, £2,172), and nonsignificant within the patient groups.Conclusions:Telemedicine was perceived by cardiologists, district clinicians, and families as reliable and efficient. The equivocal 6-month cost results indicate that investment in the technology is warranted to enhance pediatric and perinatal cardiology services.

This paper introduced a new metamorphic parallel mechanism consisting of four reconfigurable rTPS limbs. Based on the reconfigurability of the reconfigurable Hooke (rT) joint, the rTPS limb has two phases while in one phase the limb has no constraint to the platform, in the other it constrains the spherical joint center to lie on a plane. This results in the mechanism to have ability of reconfiguration between different topologies with variable mobility. Geometric constraint equations of the platform rotation matrix and translation vector are set up based on the point-plane constraint, which reveals the bifurcated motion property in the topology with mobility 2 and the geometric condition with mobility change in altering to other mechanism topologies. Following this, a unified kinematics limb modeling is proposed considering the difference between the two phases of the reconfigurable rTPS limb. This is further applied for the mechanism modeling and both the inverse and forward kinematics is analytically solved by combining phases of the four limbs covering all the mechanism topologies.

There is increasing global interest in using compost to suppress soil-borne fungal and bacterial diseases and nematodes. We studied the reproducibility of compost suppressive capacity (SC) against Pythium wilt of cucumber using nine composts produced by the same composting plant in 2008 and 2009. A bioassay was set up in a greenhouse using cucumber inoculated with two strains of Pythium. The composts were used as 20% mixtures (v:v) of a basic steam-sterilized light Sphagnum peat and sand (3:1, v:v). Shoot height was measured weekly during the 5-week experiment. At harvest, the SC was calculated as the % difference in shoot dry weight (DW) between non-inoculated and inoculated cucumbers. The SC was not affected by year of production (2008 or 2009), indicating reproducibility of SC when the raw materials and the composting method are not changed. Differences in shoot height were not as pronounced as those for shoot DW. The results were encouraging, but further studies are still needed for producing compost with guaranteed suppressiveness properties.

The present study investigates the effect of negative emotions (focusing on disappointment, sadness and regret) on cognitive schemas. The sample consist in students from the University of Bucharest (convenience groups). A univariate unifactorial experimental design was used, as the current study had one independent variable, negative emotions, and a dependent variable, cognitive schemas, which was measured with the Core Beliefs Questionnaire instrument. We applied T test for independent samples, using SPSS. The t test was statistically significant, t (45) = 2.57, p <0.05. The confidence interval (95%) for the difference between the averages is between 2.95 and 24.35. After applying the intervention, the evaluated sample (M = 43.17, SD = 29,074) showed a statistically significant difference compared to the control group (M = 29.52, SD = 11.257). The data collected support the main research hypothesis of the study, negative emotions can bring about changes in certain cognitive schemas by modifying, altering or disrupting them.
