Single-Strip Triangulation of Manifolds with Arbitrary Topology

Triangle strips have been widely used for efficient rendering. It is NP-complete to test whether a given triangulated model can be represented as a single triangle strip, so many heuristics have been proposed to partition models into few long strips. In this paper, we present a new algorithm for creating a single triangle loop or strip from a triangulated model. Our method applies a dual graph matching algorithm to partition the mesh into cycles, and then merges pairs of cycles by splitting adjacent triangles when necessary. New vertices are introduced at midpoints of edges and the new triangles thus formed are coplanar with their parent triangles, hence the visual fidelity of the geometry is not changed. We prove that the increase in the number of triangles due to this splitting is 50% in the worst case, however for all models we tested the increase was less than 2%. We also prove tight bounds on the number of triangles needed for a single-strip representation of a model with holes on its boundary. Our strips can be used not only for efficient rendering, but also for other applications including the generation of space filling curves on a manifold of any arbitrary topology.Comment: 12 pages, 10 figures.

Separating Overlapping Tissue Layers from Microscopy Images

Manual preparation of tissue slices for microscopy imaging can introduce tissue tears and overlaps. Typically, further digital processing algorithms such as registration and 3D reconstruction from tissue image stacks cannot handle images with tissue tear/overlap artifacts, and so such images are usually discarded. In this paper, we propose an imaging model and an algorithm to digitally separate overlapping tissue data of mouse brain images into two layers. We show the correctness of our model and the algorithm by comparing our results with the ground truth

Biographical Thoughts in Contemporary Tamil Poetry (2005-2007)

Literature narrates the experiences of human life. In the nineteenth and twentieth centuries, despite the emergence of various literatures, the field of poetry began to take shape with a renaissance. Poetry is the way to find the norms of human life and in the theme 'Biographical Thoughts in Contemporary Tamil Poetry (2005-2007)', the idea of life is that human beings should live in unity without selfishness. There is no destruction to the wealth of education. Therefore, it is necessary to get a compulsory education. Exercise and meditation on a daily basis suggest that there should be perseverance, that the little money saved in youth should help in old age, that family planning should be enforced to reduce population growth, that children should come forward to protect themselves without leaving their parents in a nursing home, and that hunger should be avoided. By doing so one can maintain good health. It has been explored and explored through biological thoughts that life can be prosperous and spring if alcohol, liquor and gambling are kept on the right path to prevent the mind from going astray

Updates on His bundle pacing: The road more traveled lately

His bundle pacing (HBP) has continued to evolve over the past decade and has started to become a global phenomenon. Evidence is mounting of its clinical benefits as compared to both right ventricular and left ventricular pacing. In this paper, we review recent data in support of His bundle pacing and some of the challenges facing us as we advocate its increasing role in clinical practice

Topical steroid induced Cushing’s syndrome-a rare entity

The topical steroid therapy is the commonest mode of treatment for Psoriasis. When the therapy is overused, it can cause unusual side effects like Cushing’s syndrome which is very rarely reported and we are reporting such a case. Treatment with maintenance dose of steroids is necessary based on basal cortisol levels to avert hypocortisolemic crisis in Cushing’s syndrome, however in some select asymptomatic cases maintenance dose of steroids can be withdrawn and only stress dose be given in spite of low basal serum cortisol. We managed such a case and it is reported because of its rarity in clinical practice. This can alert the clinicians to avoid prescribing steroids as maintenance dose for a long time in asymptomatic Cushing’s syndrome with low morning cortisol and thereby reducing the side effects of long-term steroids on them

Development of a risk-based maintenance (RBM) strategy for sewerage pumping station network

Industries have been facing ever-increasing challenges to do more with less under ongoing budget constraints. They are pushing the boundary by challenging the OEM recommended maintenance intervals and relaxing or tightening based on where it is needed. This is also evident in water sector where industries are trying to do targeted maintenance based on balancing costs, performances and risks. The unexpected failures, the down time associated with such failures, the environmental overflows and, the increasing maintenance costs are major challenges all wastewater reticulation and distribution networks. Industries have been working hard to increase the availability of equipment and reduce the life-cycle cost without compromising safety and environmental targets. Risk-based maintenance (RBM) strategy is useful for allocation of maintenance resources where first allocation occurs to the highest risk item and progressively allocated till it reached budget limits. This paper is based on findings from a study covering 186 sewerage pumping stations of Townsville Water in North of Queensland in Australia. This study covered identifying the critical subsystems and mitigating the risks of failure of those subsystems. Implementation of risk based maintenance strategy was useful in further enhancing reliability and reduction of maintenance costs. © 2019 IEEE.E

Weight gain in patients with tuberculosis treated under directly observed treatment short-course (DOTS)

Set up: One Tuberculosis Unit (TU) in Tiruvallur district, Tamil Nadu, India where Tuberculosis (TB) patients treated under Directly Observed Treatment Short Course (DOTS) programme. Objective: To identify the effects of weight gain among TB patients at the end of treatment on different factors such as socio-economic and demographic characteristics, smoking and drinking habits, treatment under supervision, the type of DOTS centres and problems in taking drugs. Methods: TB patients registered between May 1999 and December 2004 formed the study population. Multiple regression method was used for the analysis. Results: Among 1557 smear-positive TB patients registered under DOTS programme, the changes in weight ranged from a loss of 4 kgs to a gain of 20 kgs at the end of TB treatment; the average change in weight was 3.22 kgs. The gain in weight at the end of treatment was associated with age (<45 years), DOT at government centres, no problems in taking drugs as reported by patients and cure rate. Conclusion: The findings showed that there is an association between gain in weight with DOT at government centres and cure of patients

Keyword Specific Cloud Computing

It is now a known fact that Internet of things (Iot) and Cloud computing will be the way ahead. Store and transmit of massive amounts of data is on the cards in the coming years which will profoundly affect other areas of everyday life in the next generation. Cloud and Iot are merged together is seen as an enabler of a large number of application scenarios. As an example at the start of 2016 automakers are building a driverless taxi service. Keeping this in mind a novel idea of keyword based Cloud Computing is brought about in this paper which gives out entire data to the user if the user types the keyword of the required entity

Survival of tuberculosis patients treated under DOTS in a rural tuberculosis unit (TU), south India.

Objective: To estimate survival probabilities and identify risk factors for death of tuberculosis (TB) patients during treatment period. Methods: TB patients registered during May 1999 to December 2004 from a rural TB unit (TU) with a population of 580 000 in Tiruvallur district, South India, formed study population. Life table and Cox’s regression methods were used. Results: Of the 3818 TB patients who were initiated on treatment, 96, 94 and 97% of category – I, II and III respectively, were surviving after completion of treatment. Higher death rates were independently associated with patient’s age (45 years), previous history of treatment, alcoholism and initial body weight (<35 kgs). Conclusion: The survival probability was found to be similar in all patients irrespective of categorization. Necessary actions need to be initiated in the programme to improve body weight and abstain from alcoholism
