Reliable energy forecasting helps managers to prepare future budgets for their buildings. Therefore, a simple, easier, less time consuming and reliable forecasting model which could be used for different types of buildings is desired. In this paper, we have presented a forecasting model based on five years of real data sets for one dependent variable (the daily electricity consumption) and six explanatory variables (ambient temperature, solar radiation, relative humidity, wind speed, weekday index and building type). A single mathematical equation for forecasting daily electricity usage of university buildings has been developed using the Multiple Regression (MR) technique. Data of two such buildings, located at the Southwark Campus of London South Bank University in London, have been used for this study. The predicted test results of MR model are examined and judged against real electricity consumption data of both buildings for year 2011. The results demonstrate that out of six explanatory variables, three variables; surrounding temperature, weekday index and building type have significant influence on buildings energy consumption. The results of this model are associated with a Normalized Root Mean Square Error (NRMSE) of 12% for the administrative building and 13% for the academic building. Finally, some limitations of this study have also been discussed.
Objective: To evaluate the treatment of hydrocele and compare the post-operative course and outcome of sodium tetradecyl sulfate (3 %) (STDS) as a harmless and active sclerosant followed by aspiration with conventional hydrocelectomy for the management of adult hydrocele. Study Design: Cross Sectional, Randomized study. Setting: Liaquat University of Medical and Health Sciences, Jamshoro. Period: 1st May 2019 to 31st October 2019. Material & Methods: Fifty patients with unilateral or bilateral primary vaginal hydrocele were included in this study. Subjects with secondary vaginal hydrocele (secondary to trauma, malignancy, or epididymo-orchitis), communicating hydrocele, infected hydrocele, having a positive history of previous intervention (sclerotherapy or operation) and/or uncontrolled diabetes mellitus were excluded. Data were analyzed in SPSS version 22.0. Results: All patients were equally divided into two groups A and B. Group A (n = 25) patients were submitted to Sclerotherapy and Group B (n = 25) patients were submitted to the Conventional Surgical Hydrocelectomy. Most of the patients 24(96.0%) who underwent in Group A (Sclerotherapy, n = 25), were discharged within 1-6 days i.e. less postoperative stay whereas the majority of the patients 14(56.0%) who underwent in Hydrocelectomy group were discharged between 1 to 6 days. Patients who underwent Hydrocelectomy had more postoperative stay and in 3 cases up to 18 days. Conclusion: Sclerotherapy is the treatment of choice for primary hydrocele. Complications like pain, hematoma, and infection are less than surgical procedures. Hospital stay is minimal and does not affect the day-to-day work of the patient having sclerotherapy.
Any sort of physical disorder creates mobility difficulty especially impossible for patients with lower limb paralysis making them highly dependent on fellow human beings. To assist such patients a robotic wheelchair synchronized with eyeball motion has been developed where patients' own body part is used to help in movement. This paper devises visual research experiments to innovate the viability of an eye ball driven robotic wheelchair. It investigates the Eye-ball IR sensing and Shoulder Pressure sensing behavior linked with physical movement of patients. There are three ideas in this study. First, the correlation between Eye ball sensor behavior and the hardware model to start and stop the wheelchair. Second, shoulder pressure sensing mechanism to turn the wheelchair left and/or right. Third, Ultrasonic sensing to sense and avoid the obstacles in the path to helping free and safe movement. Experiments on different age groups show quick response at ages less than 20 for both normal and paralyzed patients with 40 and 33mV and with the ages above 45 this value reduced to 28 and 16mV respectively.
In transport aircrafts, most of the lift load is taken up by wing structure, due to which the wings of the aircraft bend upward during the flight. This results in compression and tension in upper and lower skins resulting in the plate buckling phenomenon in the skin. As buckling reduces the ability of the component to take up load, the component may eventually fail well below the design load. The structure should have a buckling factor greater than one for safe operations. In the current review, research on buckling behaviour of wing box panel of an aircraft is explored.
