Federated AI for building AI Solutions across Multiple Agencies

The different sets of regulations existing for differ-ent agencies within the government make the task of creating AI enabled solutions in government dif-ficult. Regulatory restrictions inhibit sharing of da-ta across different agencies, which could be a significant impediment to training AI models. We discuss the challenges that exist in environments where data cannot be freely shared and assess tech-nologies which can be used to work around these challenges. We present results on building AI models using the concept of federated AI, which al-lows creation of models without moving the training data around.Comment: Presented at AAAI FSS-18: Artificial Intelligence in Government and Public Sector, Arlington, Virginia, US

A comparative evaluation of I-gel and laryngeal mask airway supreme in laparoscopic surgeries: a randomized comparative study

Background: Supraglottic airway device results in less hemodynamic responses during laparoscopic surgery but supraglottic airway device to be used should have higher oropharyngeal seal pressure than peak pressure for effective ventilation as laparoscopic surgery also leads to higher airway pressure. In this study the efficiency of the I-gel with SLMA is compared in patients undergoing laparoscopic cholecystectomy surgeries.Methods: Sixty patients were randomized in to two groups, group A where I-gel was considered for airway management and group B where LMA Supreme was the device chosen for airway management.Results: Oropharyngeal seal pressure was significantly lower in group A than group B, 5 minutes after insertion of airway device it was 24.90±3.03 cm H2O and 27.30±3.41 cm H2O in group A and group B, respectively and 5 minutes after creation of pneumoperitoneum it was 25.53±3.17 cm H2O and 27.57±3.36 cm H2O in group A and group B, respectively. There was significant difference in the difference between inspiratory and expiratory tidal volume between the groups at all the time periods being higher in group A than group B. Hemodynamics were comparable between the two groups. Time taken to insert the airway device and Ryle’s tube insertion was significantly lesser in group B in comparison to group A. The percentage of complications was higher in group A than group B with no significant (p>0.05) association.Conclusions: Both the I-gel and SLMA devices can be used safely in laparoscopic cholecystectomy in non-obese patients. But in SLMA group oropharyngeal seal pressure was higher with lesser leak volume in comparison to I-gel group

Response of RLC network circuit with steady source via rohit transform

The electric network circuits are designed by using the elements like resistor R, inductor L, and capacitor Ϲ. There are a number of techniques: exact, approximate, and purely numerical available for analyzing the R L Ϲ network circuits. Since the application of numerical method becomes more complex, computationally intensive, or needs complicated symbolic computations, there is a need to seek the help of integral transform methods for analyzing the RLϹ network circuits. Integral transform methods provide effective ways for solving a variety of problems arising in basic sciences and engineering. In thispaper, a new integral transform Rohit transform is discussed for obtaining the response of a series RLϹ electric network circuit connected to a steady voltage source, and a parallel R L Ϲ electric network circuit connected to a steady current source. The response of a series R L Ϲ network circuit connected to a steady voltage source via the application of Rohit transform will provide an expression for the electric current, and that of a parallel R L Ϲ network circuit connected to a steady current source will provide an expression for the voltage across the parallel RLϹ electric network circuit. The nature of the response of such series (or parallel) network circuits is determined by the values of R, L, and Ϲ of the electric network circuit. The Rohit transform will come out to be a powerful technique for analyzing such series or parallel electric network circuits with steady voltage or current sources

Profile of epileptic patients at a tertiary care centre

Background: The present study was done in a tertiary care centre of North India to know the profile of epilepsy.Methods: Total of 210 patients were selected during the period August, 2017 to July 2018 who attended outpatient clinic of the Department of Neurology, Indira Gandhi Medical College, Shimla, Himachal Pradesh. Detailed clinical history was taken, general physical examination, and routine blood examination were carried out.Results: Of all the cases, sex ratio (male:female) was 2.39:1. A high proportion of cases (43.3%) were from lower-middle socio-economic group. 76.7% patients had generalized seizures. For 38.6% patients, frequency of seizures was more than 8 in the past 6 months. 71.9% of the patients were using only one anti-epileptic drug.Conclusions: Patients with seizures comprise a significant burden in inpatient department of developing countries

A Review on Secure Access to Cloud Storage by using ABE

Cloud computing is going to be very famous technology in IT enterprises. For an enterprise, the data stored is huge and it is very precious. All tasks are performed through networks. Hence, it becomes very important to have the secured use of data. In cloud computing, the most important concerns of security are data security and privacy. For access control, being one of the classic research topics, many schemes have been proposed and implemented. In this paper, various schemes for encryption that consist of Attribute based encryption (ABE) and its types KP-ABE, CP-ABE is explored. Public Key Encryption acts as the basic technique for ABE where it provides one to many encryptions, here, the private key of users & the cipher-text both rely on attributes such that, when the set of the attributes of users key matches set of attributes of cipher-text with its corresponding access policy, only then decryption is possible

A blockchain based architecture for asset management in coalition operations

To support dynamic communities of interests in coalition operations, new architectures for efficient sharing of ISR assets are needed. The use of blockchain technology in wired business environments, such as digital currency systems, offers an interesting solution by creating a way to maintain a distributed shared ledger without requiring a single trusted authority. In this paper, we discuss how a blockchain-based system can be modified to provide a solution for dynamic asset sharing amongst coalition members, enabling the creation of a logically centralized asset management system by a seamless policy-compliant federation of different coalition systems. We discuss the use of blockchain for three different types of assets in a coalition context, showing how blockchain can offer a suitable solution for sharing assets in those environments. We also discuss the limitations in the current implementations of blockchain which need to be overcome for the technology to become more effective in a decentralized tactical edge environment

Cervical sonomorphometric evaluation of normal and preterm labour by transvaginal and transabdominal sonography

Background: Preterm delivery is major cause of perinatal morbidity and mortality. Measuring cervical length (CL) with ultrasonography has become increasingly acceptable as an early diagnostic procedure in patients at risk for PTL, with transvaginal ultrasonography (TV Us) being considered as the gold standard for the CL assessment.Methods: A cohort of women with singleton pregnancies, and confirmed gestational age by first or early second trimester ultrasonography, last menstrual period & clinical assessment were selected to undergo transvaginal and transabdominal sonographic measurement of cervical length between 16 and 34 week gestation. Cervical length was first measured by transabdominal route (TAS) using a 3.5 MHz curved electronic array transducer with the patient in the supine position and with a full bladder, transvaginal sonography (TVS) was done by a 7.5 MHz probe attached to an ultrasound machine. The probe was covered with a latex condom and gel placed between the transducer and the cover and also on the surface. It was then gently inserted in the vagina to obtain a sagittal view of the cervix. Doppler measurement were taken by both transabdominal and transvaginal route.Results: Gradual decrease in cervical length is seen with advancement of gestation weeks. TA Us cervical length values are noted higher than TV Us however significance is seen only at 24 weeks and cervical width are showing gradual increase with advancement of gestation weeks without significant difference between them. The study compared the mean spectral Doppler parameters RI, PI and S/D Ratio at different weeks & observed that TV Us values are more at each gestation weeks than TA Us showing significant difference 24 weeks onwards.Conclusions: Although discrepancy in statistical significance, short cervical length, funneling and gland area are important to recognize for prediction of premature onset of labour, owing to the potential for perinatal morbidity and mortality and socioeconomic burden. Transvaginal sonography remains the dominant imaging modality for evaluation of the cervix. It is operator dependent modality so care should be taken to evaluate each morphologic character
