Modelling Architecture for Multimedia Data Warehouse

ABSTRACT: Data Warehouse is an information system mainly used to support strategic decision. During last few years there is a need arise to manage multimedia data in decision making process in business industry which leads to build Multimedia data warehouse. Multimedia data warehouse is a collection of large volume of image, audio, video and text data. To efficiently store, access and analyse such data there is a need arise to manage these data. Data management includes the access and storage mechanisms that support the data warehouse. Storage and retrieval of multimedia data is a critical issue for the overall system's performance and functionality. Multimedia data warehouse must be studied in order to provide an efficient environment in which data can be efficiently stored, retrieved and analyzed. In this paper, we propose the architectural framework to build multimedia data warehouse with the aim to provide better performance. To achieve better storage, access and analysis performance certain techniques are incorporated. Storage efficiency is improved by using provided compression technique and partitioning method. Access and analysis efficiency is improved by representing multimedia data by multilevel features and by applying indexing technique

Burkitt non-Hodgkin lymphoma presenting with mental neuropathy ('numb chin' syndrome) in an HIV-positive patient

Mental nerve neuropathy is usually due to local trauma or dental causes, but may be a manifestation of malignancy. A patient with virologically controlled human immunodeficiency virus (HIV) infection presented with a 'numb chin' on the background of long-standing night sweats, malaise and weight loss, worsening respiratory symptoms, and lymphadenopathy. Burkitt non-Hodgkin lymphoma was diagnosed from histology of a lymph node. Imaging (magnetic resonance imaging and18fluorodeoxyglucose [FDG]-positron emission tomography-computed tomography [PET-CT]) showed abnormal intracranial enhancement of the right mandibular nerve and extensive18FDG-avid lymphadenopathy above and below the diaphragm, focal lesions in the spleen and within the right mandible. The patient received chemotherapy and remains in clinical and radiological remission seven years later. This case highlights the need for clinicians to maintain a high index of suspicion for underlying malignancy when an HIV-infected patient presents with new onset of a 'numb chin'. Additionally, it demonstrates the importance of functional18FDG-PET-CT and neuroimaging in order to identify site(s) of pathology

Primary ovarian ectopic pregnancy: early diagnosis is the key

Ectopic pregnancy means implantation of the embryo outside the uterine cavity. It may occur in the fallopian tubes, ovaries or the cervix. Primary ovarian ectopic is a very rare condition. In such cases preservation of ovary is extremely important, particularly in patients with infertility. We report a case of primary ovarian ectopic which was managed conservatively in a patient of primary infertility. Preservation of ovary is extremely important, particularly in patients with infertility

Sildenafil citrate to improve colour doppler indices in patient with pre-eclampsia: a path less taken

Presented a case of high-risk pregnancy of an elderly primigravida who had abnormal colour doppler indices. Addition of sildenafil citrate lead to improvement of colour doppler indices and growth parameters, thus prolonging the period of gestation by 6 weeks. This led to decreased neonatal ICU stay and reduction in neonatal morbidity

Pyometra in the postpartum: a forgotten complication

We report a case of 37 years old women who conceived after in vitro fertilization (IVF). Her antenatal course was uneventful. On delivery there was placenta acreta. She later presented in the postpartum period with pyometra. She was managed with conservative treatment. We believe that the placental bed sutures and the sloughing placenta could have led to sterile pyometra in this patient. This rare but important complication need to be kept in mind specially in high risk women with thin endometrium, h/o IVF, cervical encerclage, and placenta acreta

Customised Alloy Blends for In-Situ Al339 Alloy Formation Using Anchorless Selective Laser Melting

The additive manufacturing process Selective Laser Melting (SLM) can generate large thermal gradients during the processing of metallic powder; this can in turn lead to increased residual stress formation within a component. Metal anchors or support structures are required to be built during the process and forcibly hold SLM components to a substrate plate and minimise geometric distortion/warpage due to the process induced thermal residual stress. The requirement for support structures can limit the geometric freedom of the SLM process and increase post-processing operations. A novel method known as Anchorless Selective Laser Melting (ASLM) maintains processed material within a stress relieved state throughout the duration of a build. As a result, metal components formed using ASLM do not develop signification residual stresses within the process, thus, the conventional support structures or anchors used are not required to prevent geometric distortion. ASLM locally melts two or more compositionally distinct powdered materials that alloy under the action of the laser, forming into various combinations of hypo/hyper eutectic alloys with a new reduced solidification temperature. This new alloy is maintained in a semi-solid or stress reduced state for a prolonged period during the build with the assistance of elevated powder bed pre-heating. In this paper, custom blends of alloys are designed, manufactured and processed using ASLM. The purpose of this work is to create an Al339 alloy from compositionally distinct powder blends. The in-situ alloying of this material and ASLM processing conditions allowed components to be built in a stress-relieved state, enabling the manufacture of overhanging and unsupported features

Exploration of the Continental Margins of India

In mid 1970’s the Institute prepared a plan for systematic regional geological and geophysical surveys of the continental margins of India. This involved over 75,000 km of underway (bathymetric, side scan sonar, magnetic, gravity and seismic) surveys on tracks about 20 km apart, and collection of about 1500 seabed samples at about 10 to 20 km spacing. It was anticipated that the entire programme would require 22 ship’s months. This programme received considerable impetus from sponsored surveys of other organizations, chiefly the oil industry, ports and harbours as well as industries disposing of their effluents in the marine environment. By now the entire western continental shelf and a large part of the continental slope have been covered by about 68,314 km bathymetric surveys, 12,720 km side scan sonar surveys, 46,222 km magnetic surveys, 27,200 km seismic surveys (including 5,489 km multichannel seismic), and 9,065 km gravity surveys. Approximately 1500 seabed samples have been collected. These surveys, besides providing basic information on the morphology, sediments, and geochemistry of the sediments of the .western continental margin of India, have also led to the estimation of resources of offshore ilmenite placers and low grade phosphorite deposits. The data collected are proposed to be depicted in a series of maps showing the morphology, sediments and geochemistry of sediments

Use of antiretroviral drugs to prevent the transmission and acquisition of HIV

In 2016, London became the third city in the world to achieve the United Nations 90:90:90 HIV target (90% of people living with HIV diagnosed, 90% of those diagnosed are on treatment and 90% of those on treatment have an undetectable viral load) attaining 90:97:97 (88:96:97 for England as a whole) (Public Health England, 2017). New HIV diagnoses among gay, bisexual and other men who have sex with men have also fallen for the first time since the epidemic began 30 years ago (Public Health England, 2017). This remarkable progress is a result of a combination of interventions. This editorial outlines two of these which use antiretrovirals for the prevention of transmission and acquisition of HIV

Experimental evidence on promotion of electric and improved biomass cookstoves.

Improved cookstoves (ICS) can deliver "triple wins" by improving household health, local environments, and global climate. Yet their potential is in doubt because of low and slow diffusion, likely because of constraints imposed by differences in culture, geography, institutions, and missing markets. We offer insights about this challenge based on a multiyear, multiphase study with nearly 1,000 households in the Indian Himalayas. In phase I, we combined desk reviews, simulations, and focus groups to diagnose barriers to ICS adoption. In phase II, we implemented a set of pilots to simulate a mature market and designed an intervention that upgraded the supply chain (combining marketing and home delivery), provided rebates and financing to lower income and liquidity constraints, and allowed households a choice among ICS. In phase III, we used findings from these pilots to implement a field experiment to rigorously test whether this combination of upgraded supply and demand promotion stimulates adoption. The experiment showed that, compared with zero purchase in control villages, over half of intervention households bought an ICS, although demand was highly price-sensitive. Demand was at least twice as high for electric stoves relative to biomass ICS. Even among households that received a negligible price discount, the upgraded supply chain alone induced a 28 percentage-point increase in ICS ownership. Although the bundled intervention is resource-intensive, the full costs are lower than the social benefits of ICS promotion. Our findings suggest that market analysis, robust supply chains, and price discounts are critical for ICS diffusion
