Mobile Hotspots are very popular as they use 4G-LTE (via eNodeB to the network) to provide connectivity to multiple User Equipments (UEs). Additionally, In order to improve the performance of a session from a UE which is directly connected to the eNodeB, literature has proposed Multi-Pathing (MP) concepts (Multi Path TCP, Multi Path QUIC). However, these MP concepts do not work for a UE connected to eNodeB through the hotspot. Moreover, to improve the performance of hotspot, there can be MP connections from mobile hotspot itself. First one from hotspot to LTE eNodeB (Licensed spectrum) and second to WiFi (unlicensed) Access Point (AP). To the best of our knowledge, in available literature, a hotspot device does not provide MP aggregation of licensed and unlicensed spectrums to the connected UEs. Secondly, traffic from the hotspot device majorly goes over LTE hence congesting the licensed spectrum. With respect to the above two challenges, we proposed a novel hotspot architecture called Next-Gen Mobile HotSpot (NextGen-MHS), which is a unique approach to aggregate any combination of available licensed (4G/5G) with unlicensed (WiFi/5G) spectrum and provide the aggregated connection as a Mobile-Hotspot AP. We have successfully implemented this new architecture of NextGen-MHS and conducted evaluation experiments with 4G (licensed) and WiFi (unlicensed). NextGen-MHS significantly provides better results with 80% aggregated throughput and 45% reduction in data traffic over licensed spectrum.

Background: Sleep is an integral part of any healthy individual and sleep problems can affect the intellectual abilities including the performance at school. Objectives: We studied the sleep problems among school going children in the age group of 6-16 years and the association of the sleep problems with scholastic performance in them. Materials and Methods: The study was a cross-sectional study carried out in students attending a private school. The children were given a questionnaire based on the “BEARS” screening tool for sleep problems in children to be filled by children and parents. Accordingly, the age and academic grades of students were recorded. The prevalence of sleep problems and their relation to school grades were studied. Results: Out of 229 students, 25.33% (58) students were found to have sleep problems after applying the “BEARS” criteria. Of these 58 children, 31 scored A grade, 25 scored B grade, and 2 scored C grade. 23% (31 out of 135) of A graders were found to have sleeping problems, 28% (25 out of 89) of B graders, and 40% (2 out of 5) of C graders had sleeping problems. Conclusion: Sleep problems were common in school going children. It was observed that as scholastic grades decreased, the prevalence of sleeping problems increased. Sleep problems might be one of the contributors for poor scholastic achievements in children.

Pneumatosis cystoides intestinalis (PCI) is a rare disease characterized by presence of multiple gas filled cysts in subserosal or submucosal wall of large intestine or small intestine. PCI are most commonly due to an underlying disease or can be idiopathic. Understanding of etiology and pathogenesis is necessary in each individual case for appropriate management. Thirty eight enteral resected specimens were studied from January 2008 to September 2011 in PESIMSR. Clinical and morphological characteristics of the 3 cases with histological diagnosis of PCI found, were studied and compared with other studies.

Objectives: To describe the epidemiology and clinical profile of cases of HFMD in an outbreak. Design: Descriptive epidemiological study. Setting: Tertiary care center in North Bangalore. Methods: Patients attending to M.S.Ramaiah medical college hospital with features suggestive of HFMD were included in the study. The patient's demographic data, clinical features and examination findings were entered in to a predesigned format. The epidemiol- ogy and clinical features were analyzed using appropriate statistical methods. Results: A total of 71 children were diagnosed as HFMD disease, 47 (66.2%) were boys and 24 (33.8%) were girls, fever was seen in 62 (87.3 %) of the affected children, anorexia and sore throat was seen in 47 (66.2 %) and 35 (49.3%) children respectively. Typical rashes were seen on hands in 67 (94.4%), 64 (90.1%) had rashes on feet, 58 (81.7%) had mouth ulcers, and 37 (52.1%) had rashes on buttocks. There was history of exposure to a HFMD in 46 (64.8%) of the children mostly at home in 19 (26.8%), at day care centers in 14 (19.7%) and in 13 (18.3%) at school. The disease lasted between 2 days to 8 days. There were no complications noted. Conclusion: HFMD affected mainly children in the age group of 1-10 years, affected more boys than girls, complete recovery without any major complications was seen in the present outbreak. The characteristic clinical features will be helpful in early diagnosis of HFMD and will help in looking for any complications occurring in HFMD.

Scalable video coding has been highlighted by the High Efficiency Video Coding (HEVC) which has efficient techniques to compress the video size considerably. However, video transmissions over wireless network have remained a challenge due to its limitations on bandwidth and time varying nature of its parameters. This paper presents a novel Inter Frame-Rate Distortion (IF-RD) optimization method for video compression in HEVC using a technique that produces the relationship between levels of transform coefficient and its samples by linear signal model. A quadratic program is used to optimize this problem, however, RD optimization is done on mode selection scheme. The results are presented in the form of Bit rate, PSNR, complexity of computation. The RD improvisation is indicated by Structural Similarity Index (SSI) with respect to Bit rate. Finally the results show a greater improvisation in PSNR, reduction in Computational complexity and increase in SSI. The encoded video can be transmitted in low bandwidth channels like wireless medium.

Creating e-learning Content Storyboard Based on Instructional Design Principles provides learners with the opportunity to enhance their learning experience through greater interaction with course material and the ability to control their learning environment. A fast dissemination of knowledge is a critical element to organizational success. It also gives recommendations for future studies that could be conducted based on t
