On Optimal and Fair Service Allocation in Mobile Cloud Computing

This paper studies the optimal and fair service allocation for a variety of mobile applications (single or group and collaborative mobile applications) in mobile cloud computing. We exploit the observation that using tiered clouds, i.e. clouds at multiple levels (local and public) can increase the performance and scalability of mobile applications. We proposed a novel framework to model mobile applications as a location-time workflows (LTW) of tasks; here users mobility patterns are translated to mobile service usage patterns. We show that an optimal mapping of LTWs to tiered cloud resources considering multiple QoS goals such application delay, device power consumption and user cost/price is an NP-hard problem for both single and group-based applications. We propose an efficient heuristic algorithm called MuSIC that is able to perform well (73% of optimal, 30% better than simple strategies), and scale well to a large number of users while ensuring high mobile application QoS. We evaluate MuSIC and the 2-tier mobile cloud approach via implementation (on real world clouds) and extensive simulations using rich mobile applications like intensive signal processing, video streaming and multimedia file sharing applications. Our experimental and simulation results indicate that MuSIC supports scalable operation (100+ concurrent users executing complex workflows) while improving QoS. We observe about 25% lower delays and power (under fixed price constraints) and about 35% decrease in price (considering fixed delay) in comparison to only using the public cloud. Our studies also show that MuSIC performs quite well under different mobility patterns, e.g. random waypoint and Manhattan models

Blood Glucose Regulation Using Labview

Diabetes mellitus (DM), commonly referred to as diabetes, is a group of metabolic diseases in which there are high blood sugar levels over a prolonged period. If not regulate the glucose level then it will cause the serious damage to heart, kidneys, eyes, and nerves. The pancreas produces insulin to absorb the glucose. In type I diabetes the pancreas does not secrete insulin to compensate this artificial pancreas will be used. The artificial pancreas will mimic the function of pancreas it consists of a sensor, controller and insulin pump. The sensor continuously monitors glucose, the amount of insulin required will be calculated using a controller then injected using insulin pump this is the function of the artificial pancreas. The food we take is converted into glucose. So, meal intake will greatly affect the glucose levels, in this paper a closed loop model is developed based on Bergman\u27s minimal model and meal intake is introduced as a disturbance then the control action is performed using Fuzzy and PID controller using LABVIEW software.  So, from this, if the glucose concentration exceeds/decreases, above/below a certain point necessary control action will be taken

Study of serum cobalamin level in vegetarian v/s nonvegetarian geriatric individuals

Background: Vegetarianism is found in all geographic areas, they may have lower B-12 levels than nonvegetarian; problem could be graver in elderly. This study intended to recognise geriatric individuals with B-12 deficiency so as to save them from anaemia, dementia & neuropsychiatric disturbances by timely recommendations for supplementation.Methods: Current study was conducted on 200 healthy attendants divided in to two groups- A comprised of 100 vegetarian and B of 100 nonvegetarian geriatric individuals (> 60yrs.), they had no previous chronic disease and an attempt was made to exclude diabetes mellitus, hypertension, chronic gastritis, hypoplastic & aplastic anaemia. Those with history of alcohol intake, PPI therapy & regular vitamin supplementation were excluded. Complete clinical examination and routine blood tests were done. Serum cobalamin level was determined by ACCU-BIND ELISA Microwells method.Results: Total of 58 vegetarians were found to be B-12 deficient compared to 42 normal (>350pg/ml) this was statistically significant. Out of 100 nonvegetarian 48 were deficient while 52 had normal levels this too was statistically significant. On comparing the vegetarians and non vegetarian groups significant result was obtained (p <0.01). When different age groups were statistically compared insignificant result was obtained, same was true for gender distribution. Statistically significant result was obtained on comparing vegetarian Vs nonvegetarian group.Conclusions: Irrespective of the dietary habit B-12 deficiency is prevalent in elderly, as 58% of vegetarian & 48% of nonvegetarian were found B-12 deficient, detailed dietary analysis revealed that majority of them consumed nonvegetarian food only occasionally. No significant effect of increasing age & gender was found on B-12 levels in either group. Every elderly vegetarian or non vegetarian irrespective of gender should get their B-12 levels checked & if found low should receive B-12 supplement.

ANC with acute abdomen: a case report from secondary care hospital, Western Maharashtra

Female body undergoes numerous anatomical and physiological changes in pregnancy which make diagnosis and management of acute abdomen in pregnancy as a most challenging situation. This may lead to dilemma and delayed identification of spectrum of causes of acute abdomen in pregnancy ultimately resulting in maternal and foetal morbidity and mortality. This case was to identify the spectrum of causes, the clinical presentation and diagnostic dilemma of acute abdomen in pregnancy. We presented one of the unusual and rare cause of acute abdomen with hemoperitoneum. Patient underwent emergency laparotomy with peritoneal wash with no obvious bleeding cause but evidence pointing towards vascular tumour or sub-serosal fibroid. The diagnosis remained obscured. The dilemma was attributed to higher radiological imaging with possibility of Haemorrhagic corpus luteum and non-viable heterotopic pregnancy. The cause of bleeding could not be identified with higher imaging due to contraindicated use of contrast enhanced MRI/CT and other alternatives due to radiation exposure in pregnancy. Diagnosis and treatment of acute abdomen in pregnancy should be individualized for better prognosis. Good clinical acumen is essential for ordering early diagnosis and intervention in acute abdomen in pregnancy

Search for an Instability on a Quenched-Liquid Interface

We searched for signs of an instability on the interface between the two phases of a binary-liquid mixture, isobutyric acid and water, after the mixture was quenched further into the two-phase region. Such an instability would be the liquid-liquid analog of the Mullins-Sekerka instability seen in quenched alloys. Never is any dramatic growth observed, but under conditions of small dimensionless quench depth (theta\u3c1.5×10−3), the intensity of light scattered from the interface grows for small values of the momentum transfer k

Irbesartan, an angiotensin type 1 receptor inhibitor, regulates markers of inflammation in patients with premature atherosclerosis

AbstractOBJECTIVESThis study assessed the role of angiotensin II type 1 (AT1) receptor antagonists on inflammatory mechanisms involved in atherogenesis. Specific inflammatory markers included solubilized tumor necrosis factor-alpha receptor II (sTNF-αRII), vascular cell adhesion molecule-1 (VCAM-1) and superoxide. In addition, the AT1receptor blocker irbesartan was evaluated for its ability to suppress these markers in individuals with atherosclerosis.BACKGROUNDMechanisms involved in the complex process of atherogenesis include alterations in the inflammatory responses. The use of compounds that suppress these responses may reduce the degree of damage seen in atherosclerosis.METHODSWith a cross-sectional study design, 33 normotensive patients with stable coronary artery disease (CAD) were treated with irbesartan for a 24-week period. These patients were compared against a control population with no known coronary atherosclerosis. Marker levels were measured by enzyme-linked immunosorbent assay technique and lucigenin chemiluminescence assay and statistically evaluated by two-way repeated measures analysis of variance.RESULTSAll patients with coronary artery disease had increased levels of inflammatory molecules over those of control patients. Treatment with irbesartan in these patients significantly reduced levels of inflammatory molecules measured. Soluble VCAM-1 levels were reduced by 36%; soluble TNF-alpha levels were reduced by 54% and superoxide level decreased by 52%. Maximal suppression of inflammatory markers by irbesartan therapy in patients with CAD was seen at 12 weeks.CONCLUSIONSThe effect of irbesartan on each inflammatory marker is significant. Our results show that use of irbesartan may retard the inflammatory process seen in premature forms of atherosclerosis

Evidence for Coupling of Velocity and Composition Fluctuations in a Binary Liquid Mixture

A critical mixture of isobutyric acid and water was quenched from the one-phase region into the two-phase region and, after the spinodal ring was well developed, a reverse quench returned the system to the one-phase region. Light-scattering measurements for this process exhibit a clearly nondiffusive relaxation which, at least for early times after the quench reversal, is in good agreement with Ruiz\u27s scheme for the coupling of velocity and composition fluctuations
