    Image classification and object recognition are some of the most prominent problems in computer vision. The difficult nature of finding objects regardless of pose and occlusions requires a large number of compute resources. Recent advancements in technology have made great strides towards solving this problem, and in particular, deep learning has revolutionized this field in the last few years. The classification of large datasets, such as the popular ImageNet dataset, requires a network with millions of weights. Learning each of these weights using back propagation requires a compute intensive training phase with many training samples. Recent compute technology has proven adept at classifying 1000 classes, but it is not clear if computers will be able to differentiate and classify the more than 40,000 classes humans are capable of doing. The goal of this thesis is to train computers to attain human-like performance on large-class datasets. Specifically, we introduce two types of hierarchical architectures: Late Fusion and Early Fusion. These architectures will be used to classify datasets with up to 1000 objects, while simultaneously reducing both the number of computations and training time. These hierarchical architectures maintain discriminative relationships amongst networks within each layer as well as an abstract relationship from one layer to the next. The resulting framework reduces the individual network sizes, and thus the total number of parameters that need to be learned. The smaller number of parameters results in decreased training time

    Coal based thermal power plants more or less producing 150 tons of fly ash each year. Endeavours to utilize fly ash powder have come to just a twenty to thirty percent reutilization rate. Around 80 percent of the power generation is from coal based power plants; rest on gas and oil. As most of the power plants are using bituminous coal and sub-bituminous coal leading towards high production of fly ash. Due to high percent of ash in the coal give rise to large volumes of fly ash. Utilization is becoming huge problem in India. The country’s dependence on coal for power generation has unchanged so we need to look at the strategies to encourage and establish technological concepts to utilize fly ash in bulk. We have plenty of uses of fly ash, but we need to analyse the uses such that effective utilization of fly ash takes place. Production of fly ash depends upon the coal source, plant operations and many more factors. The various fly ash characteristics are discussed including classifications, physical characteristics, chemical properties and chemical compositions. In spite of the fact that far reaching examination has been performed on the utilization of fly ash and took environmental concerns also a major problem like mobilization of toxic elements, biota impact, microbial impact, handling dangers, and pertinent regulations. Finally, extensive research has done to reutilization of fly ash and recommendation is provided to cover deficiencies found in the literature

    the present a scheme that permits a more fine-grained trade-off. The intuition is that outsourced data may require different levels of the protection, depending on how to popular it is: content shared by many users, such as popular song or video, arguably requires less protection than a personal document, the copy of a payslip or the draft of an un submitted scientific paper. Unfortunately, semantically secure encryption schemes render various cost-effective storage optimization techniques, such as the data de duplication, ineffective. We present a novel idea that differentiates data according to their popularity. Based on this idea, we design an encryption scheme that the guarantees semantic security for the unpopular data and provides weaker security and better storage and bandwidth benefits for popular data

    A technological intervention has been the major impetus for the rapid development of recirculating aquaculture system (RAS) for nurery rearing of marine fishes across the world. In spite of the various technologies available for the fulfilment of high production and proper installation of the RAS, it is necessary to optimise many factors periodically and to customize the RAS according to the species, area and scope of application. In this context, developing standard operating protocols for the nursery rearing of Indian pompano in customised RAS is utmost necessary to promote good growth of fishes and to obtain optimal production in a sustainable manner from RAS. A standard operating protocol for nursery rearing of Indian pompano, Trachinotus mookalee is provided below. The present SOP was developed on the basis of various experiments in Visakhapatnam Regional Centre of ICARCMFRI, Visakhapatnam

    Recirculating Aquaculture System engineering: Design, components and construction

    Most fish and crustacean aquaculture is undertaken in earthen ponds or large tanks with flowing water. Pond culture requires large areas of flat land and significant quantities of clean groundwater. Flow-through tank aquaculture requires less land but needs more water per kg of fish produced to maintain good growing conditions within the tank. Recirculating aquaculture systems re-use water over and over, cleaning the waste from the water and providing oxygen to the fish. Because water is reused, recirculating fish production systems utilize only a fraction of the water required by traditional fish production techniques. A small domestic well producing three to five gallons per minute, when coupled with the proper recirculating technology, can be used in the production of thousands of kilo of fish annually. There is no doubt that fish can be reared in large quantities and at high densities in recirculating systems. However, the economic viability of growing fish in recirculating systems is not ascertained. Before initiating the fish culture using recirculating technology, essential googleprinciples involved in the technology being used must be understood. In almost every successful application, highly technological solutions that have been evaluated are incorporated into the aquaculture systems

    Treatment of severe neutropenia with high-dose pyridoxine in a patient with chronic graft versus host disease and squamous cell carcinoma: a case report

    <p>Abstract</p> <p>Introduction</p> <p>The differential diagnosis of neutropenia includes medications, infections, autoimmune diseases, and deficiencies of Vitamin B12 and folate. The association of Vitamin B6 deficiency with severe neutropenia is a rare finding.</p> <p>Case presentation</p> <p>A 51-year-old Caucasian woman presented with fever and profound neutropenia (48 neutrophils/uL). Her clinical history included non-Hodgkin lymphoma, in remission following treatment with allogeneic bone marrow transplantation, quiescent chronic graft-versus-host disease, and squamous cell carcinoma of the skin metastatic to cervical lymph nodes. Medications included atenolol, topical clobetasol, Ditropan (oxybutynin), prophylactic voriconazole, prophylactic valganciclovir, Soriatane (acitretin), and Carac (fluorouracil) cream. The bone marrow was hypocellular without metastatic cancer or myelodysplasia. Neutropenia did not respond to stopping medications that have been associated with neutropenia (valganciclovir, voriconazole and Soriatane) or treatment with antibiotics or granulocyte colony stimulating factor. Blood tests revealed absence of antineutrophil antibodies, normal folate and B12 levels, moderate zinc deficiency and severe Vitamin B6 deficiency. Replacement therapy with oral Vitamin B6 restored blood vitamin levels to the normal range and corrected the neutropenia. Her cervical adenopathy regressed clinically and became negative on scintography following Vitamin B6 therapy and normalization of the blood neutrophil count.</p> <p>Conclusion</p> <p>Severe pyridoxine deficiency can lead to neutropenia. Screening for Vitamin B6 deficiency, along with folate and Vitamin B12 levels, is recommended in patients with refractory neutropenia, especially those with possible malabsorption syndromes, or a history of chronic-graft-versus host disease. Severe neutropenia may facilitate progression of squamous cell carcinoma.</p

    Conventional cytogenetics and interphase fluorescence in situ hybridization (FISH) identify high-risk multiple myeloma (HRM) populations characterized by poor outcomes. We analyzed these differences among HRM versus non-HRM populations after upfront autologous hematopoietic cell transplantation (autoHCT). Between 2008 and 2012, 715 patients with multiple myeloma identified by FISH and/or cytogenetic data with upfront autoHCT were identified in the Center for International Blood and Marrow Transplant Research database. HRM was defined as del17p, t(4;14), t(14;16), hypodiploidy (-Y) or chromosome 1 p and 1q abnormalities; all others were non-HRM. Among 125 HRM patients (17.5%), induction with bortezomib and immunomodulatory agents (imids) was higher compared with non-HRM (56% versus 43%, P \u3c .001) with similar pretransplant complete response (CR) rates (14% versus 16%, P .1). At day 100 post-transplant, at least a very good partial response was 59% in HRM and 61% in non-HRM (P = .6). More HRM patients received post-transplant therapy with bortezomib and imids (26% versus 12%, P = .004). Three-year post-transplant progression-free (PFS) and overall survival (OS) rates in HRM versus non-HRM were 37% versus 49% (P \u3c .001) and 72% versus 85% (P \u3c .001), respectively. At 3 years, PFS for HRM patients with and without post-transplant therapy was 46% (95% confidence interval [CI], 33 to 59) versus 14% (95% CI, 4 to 29) and in non-HRM patients with and without post-transplant therapy 55% (95% CI, 49 to 62) versus 39% (95% CI, 32 to 47); rates of OS for HRM patients with and without post-transplant therapy were 81% (95% CI, 70 to 90) versus 48% (95% CI, 30 to 65) compared with 88% (95% CI, 84 to 92) and 79% (95% CI, 73 to 85) in non-HRM patients with and without post-transplant therapy, respectively. Among patients receiving post-transplant therapy, there was no difference in OS between HRM and non-HRM (P = .08). In addition to HRM, higher stage, less than a CR pretransplant, lack of post-transplant therapy, and African American race were associated with worse OS. In conclusion, we show HRM patients achieve similar day 100 post-transplant responses compared with non-HRM patients, but these responses are not sustained. Post-transplant therapy appeared to improve the poor outcomes of HRM
