A learners experience with the games education in software engineering

The utilization of games and its components in software building training isn’t new. In reality, their usage in Software development training is found to look into papers for numerous decades. Be that as it may, there is little data about the real reception of these methodologies in games designing and development training in terms of software building. Consequently, the objective of this paper is to research the utilization of game’s components in programming designing instruction, in the viewpoint of teachers. To accomplish this objective, this examination proposes and breaks down the aftereffects of a study replied by numerous product designing teachers. We test the members by welcoming multiple instructors from settled colleges and instructive organizations of various districts. The first objective of the review is to gather data relates to the utilization of important games and rich gamification in the student classrooms, and the second objective is to comprehend information territories and the pre-owned game-related techniques. The outcomes show that the more significant part of the educators knows about these instructive methodologies, the games were embraced by various members. Games that are generally played to cover “Programming Process” & “Task Management.” The utmost utilized game apparatuses are Points scoring, Quizzes solving, and meet challenges. The outcomes additionally reveal that the fundamental explanations behind not embracing the assets are the absence of information, lack of data about essential games for encouraging programming designing, and the absence of time to design and remember these methodologies for the classes At long last, results show a definite propensity towards the future appropriation of these game-related methodologies by the product developing teachers

Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial

Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124. Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid (5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82–1·18). Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of 5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98). Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a randomised trial

Implementation of Cloud Computing for SMEs

Abstract Cloud computing is becoming more and more popular, especially for businesses and organizations. A lot of enterprises are shifting to the clouds because it offers a lot of benefits. With cloud computing, SMEs no longer have to maintain software and servers on their premises. There is no need to employ highly technical personnel to maintain the IT infrastructure. What businesses do now is that they rent a space on a server located anywhere in the world so that they can access their software applications. A lot of large businesses have moved to the clouds and it is expected that small and medium-sized businesses will follow suit. SMEs can enjoy a lot of benefits when they shift to the clouds. One of such benefits is that they can save on costs. There is no need to invest on hardware and not use it fully. With cloud computing, SMEs can pay only for what they have utilized. They have the option to choose the kind of service level they require. Cloud computing service providers take care of IT support, licenses, and costly equipment. They also ensure that they have the newest software versions installed on their systems. Thus, SMEs need not worry about software installations and updates. Also, cloud computing service providers employ IT experts who can help users with their needs. The aim of this research work is to provide an overview of the implementation of cloud computing for Small and Medium Enterprises to help them make strategic decisions regarding the adoption of cloud computing within their own environment

Forecasting Hydrogen Production from Wind Energy in a Suburban Environment Using Machine Learning

The environment is seriously threatened by the rising energy demand and the use of conventional energy sources. Renewable energy sources including hydro, solar, and wind have been the focus of extensive research due to the proliferation of energy demands and technological advancement. Wind energy is mostly harvested in coastal areas, and little work has been done on energy extraction from winds in a suburban environment. The fickle behavior of wind makes it a less attractive renewable energy source. However, an energy storage method may be added to store harvested wind energy. The purpose of this study is to evaluate the feasibility of extracting wind energy in terms of hydrogen energy in a suburban environment incorporating artificial intelligence techniques. To this end, a site was selected latitude 33.64° N, longitude 72.98° N, and elevation 500 m above mean sea level in proximity to hills. One year of wind data consisting of wind speed, wind direction, and wind gust was collected at 10 min intervals. Subsequently, long short-term memory (LSTM), support vector regression (SVR), and linear regression models were trained on the empirically collected data to estimate daily hydrogen production. The results reveal that the overall prediction performance of LSTM was best compared to that of SVR and linear regression models. Furthermore, we found that an average of 6.76 kg/day of hydrogen can be produced by a 1.5 MW wind turbine with the help of an artificial intelligence method (LSTM) that is well suited for time-series data to classify, process, and predict

Facile Synthesis of ZnSe/Co₃O₄ Heterostructure Nanocomposites for the Photocatalytic Degradation of Congo Red Dye

In the present paper, simple hydrothermal and solid-state methods are reported for the synthesis of metal chalcogenide (ZnSe), metal oxide (Co3O4) and their nano-heterostructure (ZnSe/Co3O4 3:1, 1:1 and 1:3 ratios by weight), while their photocatalytic efficiencies are also investigated. The X-ray diffraction results corroborate the good crystallinity and purity of all synthesized products, i.e., ZnSe, Co3O4 and their nanocomposites. The scanning electron micro-images of ZnSe show a mixed morphology of nanoparticles (≈16 nm), including spherical and distorted cubes, while Co3O4 has a worm-like morphology (≈20 × 50 nm). The EDX results show that all the elements are present in accordance with their anticipated amounts in the products. The UV/visible absorption spectrum of ZnSe depicts a sharp absorption at around 480 nm, while Co3O4 demonstrates two prominent peaks, 510 nm and 684 nm. The prepared samples were employed for the photocatalytic degradation of Congo red dye and the nano-heterostructure (ZnSe/Co3O4 3:1) shows an exceptional photocatalytic degradation efficiency of 96%. This enhanced photocatalytic activity was due to the synergic effect of ZnSe and Co3O4 that reduced the electron/hole recombination and caused suitable bandgap alignment
