The algorithm proposed in this dissertation attempts to achieve this fine balance between the accuracy and speed that such a system must posses. The mathematical morphology operators of dilation and erosion are utilized to identify the region within an image which contains the license plate. Using the concept of color coherence vectors, an image recognition algorithm is presented which utilizes this extracted region and compares it as a whole to other images of license plates, in the database. The application developed for the testing of this algorithm works with an accuracy of eighty eight percent and an average processing time of two seconds per image.

An investigation was carried out with maize crop in kharif season during 2015-2016 under long-term interagted nutrient management module and examine its approach on soil organic carbon and aggregation. The soil aggregate formation was separated using a wet sieving method. The large macroaggregates varied from 3-10 % under different treatments whereas, about 72-82% of aggregate corresponded to small macro-aggregates (0.25–2 mm) followed by micro-aggregates which constituted about 12-17%. Application of organics increased the proportion of small macro-aggregates. The highest content was recorded in T3, T4, T11 and T12. This is because soil organic matter has been recognized as binding agent of soil particles for the formation of water stable aggregates. It was observed that there was improvement in the percentage of water stable aggregates (>250 mm) due to integrated use of recomme...

Making graphene a superconductor at large scales is however a long-lasting challenge. A possible solution relies on epitaxially-grown graphene, using a superconducting substrate. Such substrates are scarce, and usually destroy the Dirac character of the electronic band structure. Using electron diffraction (reflection high-energy, and low-energy), scanning tunneling microscopy and spectroscopy, atomic force microscopy, angle-resolved photoemission spectroscopy, Raman spectroscopy, and density functional theory calculations, we introduce a strategy to induce superconductivity in epitaxial graphene viaviavia a remote proximity effect, from the rhenium substrate through an intercalated gold layer. Weak graphene-Au interaction, contrasting with the strong undesired graphene-Re interaction, is demonstrated by a reduced graphene corrugation, an increased distance between graphene and the underlying metal,...

However, PEEP may not prove beneficial in all cases. Factors affecting the action of PEEP have not been elucidated well and remain controversial. Pulmonary vasculature has direct bearing on the action of PEEP as has been proven in the previous studies. Thus, this prospective study was planned to evaluate the action of PEEP on the basis of pulmonary artery systolic pressure (PASP) which is noninvasive and easily measured by transthoracic echocardiography. Seventy morbidly obese patients, the American Society of Anesthesiologists Grade II, or III, aged 20-65 years with body mass index >40 kg/m2, scheduled for elective laparoscopic bariatric surgery were included. Patients who denied consent, those undergoing emergency and/or open surgery and those requiring >2 attempts for intubation were excluded from the study. Ten patients had to be excluded. Thus, a total of sixty patients participated in the study. Thirty patients received no PEEP at the time of induction while other thirty patients were given a PEEP of 10 cm of H2O. Serial ABG samples were taken preoperatively, at the time of intubation, 5 min after intubation, and 10 min after intubation. Patients were then divided into four groups on the basis of PASP value of ≤30 mm Hg with and without PEEP or >30 mm Hg with and without PEEP. The primary outcome was the effect of PEEP of 10 cm of H2 O on ABG and hemodynamics in morbidly obese patients. The secondary outcome was the effect of PASP on the action of PEEP in morbidly obese patients undergoing laparoscopic surgery. Patients having PASP of >30 mm Hg had significant improvement in oxygenation on PEEP application (270.11 ± 119.26 mm Hg) as compared to those without PEEP (157.57 ± 109.29 mm Hg) just after intubation. The increase in oxygenation remained significant at all time intervals. Patients with PASP ≤30 mm Hg did not show significant improvement in oxygenation with PEEP application (177.09 ± 85.85 mm Hg as compared to 226.27 ± 92.42 mm Hg without PEEP). Hemodynamic parameters did not show statistically significant alterations. Morbidly obese patients who have PASP >30 mm Hg benefit most from the PEEP. Thus, PASP which is an easily measurable noninvasive parameter can be used as a criterion for selecting patients who benefit from PEEP application.

However, sparse information can be gathered from the literature regarding its effect when applied at the time of induction and the time of onset of its effect. Thus, this study was planned to assess the effect of PEEP when applied for a single minute in morbidly obese patients. This was a randomized prospective study comprising seven morbidly obese patients (body mass index ≥40 kg/m(2)). Control group included 30 patients who received no PEEP at the time of induction. The study group consisted of thirty patients who were given a PEEP of 10 cmH2O. Serial arterial blood gas samples were taken preoperatively, at the time of intubation, 5 min after intubation and 10 min after intubation. PaO2 was significantly higher in test group (242.0 ± 116.0 mmHg) than in control group (183.0 ± 107.0 mmHg) just after intubation. PaCO2 was comparable in control group (43.73 ± 6.32 mmHg) and test group (44.52 ± 6.33 mmHg) just after intubation but was significantly less in test group than in control group at 5 and 10 min thereafter. Hemodynamic parameters were comparable in both groups at all time intervals. Application of even a single minute of PEEP at the time of induction improves oxygenation without any adverse effects on hemodynamics, in morbidly obese patients undergoing laparoscopic Bariatric surgery.

The study presented aims at determining the seismic wave attenuation factors namely, scattering attenuation and intrinsic absorption.Determination of the two factors require estimation of two parameters namely, seismic albedo and extinction length. The method of multiple lapse time window analysis is employed to estimate the two factors. Here, multiple finite lapse time windows of 0-15, 15-30 and 30-45 seconds are used for analysis. The mean square amplitudes of band pass filtered seismogram (1-2, 2-4, 4-8 Hz) data is averaged over the time windows to estimate the seismic energy. This energy is corrected for local site amplification and source effects. Coda normalization is employed for this purpose. The energy obtained is further corrected for geometrical spreading. Finally, the normalized energy is plotted with respect to the hypocentral distance. The synthetic energy distribution is obtained from Monte Carlo simulation.

Steel pipe piles are economical for long piles into deeps loose soil. Till now most of research has been directed towards the response of individual piles to vertical loads. The present investigation was performed to study the load settlement characteristics of rectangular, square and circular pile groups under axial load conditions. The load was applied at the top of pile cap with the help of jack. The behaviors of thirteen pile groups were studied. The spacing of piles at the bottom of pile cap was kept 2.5d in each case where d is diameter of the pile for testing. The piles were arranged in planes perpendicular to the direction of load and were symmetrical. Tests were conducted in laboratory under controlled density conditions using dry, clean, uniform sand. Only deflections at ground level were measured.

Using American Well's platform, patients with non-emergency health concerns can communicate with physicians online or by phone and receive advice or even a diagnosis without having to visit the physician's office. American Well's co-founders, Ido Schoenberg and Roy Schoenberg, believe this platform will reduce the cost of care delivery, create new revenue-earning opportunities for providers, and contribute to a more efficient, convenient healthcare delivery system. While the platform could benefit insurers, providers, employers, and patients alike, the company has only marketed to a few health insurance companies to date. In November 2009, three insurers have adopted the technology and American Well expects several more to do so over the next 12 months. As the company plans to accelerate adoption by health insurers, it is also considering other growth options. Is it too early to commit resources to developing and marketing American Well's second-generation product, which facilitates real-time connectivity between primary care physicians and specialists? Should American Well pursue new markets in the U.S., such as hospitals, chains of clinics, and pharmacies, or even expand internationally? In a broader sense, American Well's technology solves the economic obstacle of time and place by connecting excess supply (of physician capacity) with excess demand (for patient care). Could this model be adapted to other industries, such as legal and accounting services? Alternatively, should American Well continue to focus solely only on its primary product and on becoming the leader in the Online Care Industry?Learning Objective:Examine how a novel service, in the context of healthcare, should think about its next-generation offerings and markets.
