Deep models have recently shown improved performance on numerous benchmark tasks in computer vision and machine learning. The availability of huge amount of digital data, possibility of massively parallel computations on graphics processing units and the development of advance optimisation techniques have pushed the limits of the deep learning framework by superseding the performance of state-of-the-art research, in specific the kernel methods. This research proposes a novel connection between the two paradigms of research and shows empirical evidence to emphasise that the knowledge learnt from one domain could be supplemented with the significant properties of the other domain to achieve the best of both the worlds. The proposed hybrid methodology illustrates the advantages of deep architectures for kernel methods by showing significant improvement in the classification performance on benchmark tasks with kernel methods. It is shown empirically that the results achieved are either better or competitive to the leading benchmarks from support vector machines and deep models. © The Institution of Engineering and Technology 2017.

Housing Studies | Year: 2017

This paper investigates living conditions in Indian slums, extent of improvement of basic services between 2002 and 2012 and determinants of improvement based on National Sample Survey data. The pace of slum improvement has increased over the study period. Slums devoid of basic services have reduced in 2012 as compared to 2002. Security of tenure, strengthened especially through notification of slums, appears to be one of the most important determinants of slum upgradation. Improvements of electricity and water supply spur improvements of other basic services. Better approach roads lead to better housing but motorable pucca (tarmac) approach road or proximity to motorable road reduces likelihood of better housing. Government is the major provider of services in slums. The role of NGOs in improvement of basic services within slums has declined over time along with decline in associations for slum improvement. The paper advocates transfer of full property rights to slum dwellers and integration of different institutions for slum improvement. © 2017 Informa UK Limited, trading as Taylor & Francis Group

The cloud phenomenon is quickly becoming an important service in Internet computing. Infrastructure as a Service (IaaS) in cloud computing is one of the most significant and fastest growing field. In this service model, cloud providers offer resources to users/machines that include computers as virtual machines, raw (block) storage, firewalls, load balancers, and network devices. One of the most pressing issues in cloud computing for IaaS is the resource management. Resource management problems include allocation, provisioning, requirement mapping, adaptation, discovery, brokering, estimation, and modeling. Resource management for IaaS in cloud computing offers following benefits: scalability, quality of service, optimal utility, reduced overheads, improved throughput, reduced latency, specialized environment, cost effectiveness and simplified interface. This paper focuses on some of the important resource management techniques such as resource provisioning, resource allocation, resource mapping and resource adaptation. It brings out an exhaustive survey of such techniques for IaaS in cloud computing, and also put forth the open challenges for further research. © 2013 Elsevier Ltd.

Small hospitals are the grassroots for the big hospital structures, so proper waste management practices require to be initiated from there. Small hospitals contribute a lot in the health care facilities, but due to their poor waste management practices, they pose serious biomedical waste pollution. A survey was conducted with 13 focus questions collected from the 100 hospital present in Dehradun. Greater value of per day per bed waste was found among the small hospitals (178 g compared with 114 g in big hospitals), indicating unskilled waste management practices. Small hospitals do not follow the proper way for taking care of segregation of waste generated in the hospital, and most biomedical wastes were collected without segregation into infectious and noninfectious categories. © Springer Science+Business Media B.V. 2011.

Reviews of Environmental Contamination and Toxicology | Year: 2011

Heavy metals (HMs) are natural components of the Earth's crust and are usually present in all environmental matrices. However, the concentration of several HMs has increased several fold in some ecosystems as a result of anthropogenic activities. Heavy environmental metal contamination has continued to gain global attention, mainly because of the toxicological risks posed by such metals to human health (Ayodeji and Olorunsola 2011). Although metallic elements are often essential for living organisms, they become toxic when present at high concentrations (Elekes et al. 2010). The rapid increase in human population, coupled with haphazard industrialization and technological advancement, has caused many serious environmental problems around the world; among the causes of such problems is the production and release of toxic metals. In the past few decades, the concentration of heavy metals in soil and surface waters has increased (Nriagu and Pacyna 1988; Larison et al. 2000) and now constitutes a potential threat to terrestrial and aquatic biota (Ives and Cardinale 2004; Nasim and Dhir 2010) and to humans by entering the food chain (Hsu et al. 2006; Meena et al. 2008). Because of the widespread presence of heavy metals in the environment, their residues also reach and are assimilated into medicinal plants. © 2011 Springer Science+Business Media, LLC.

Recent development in group of Fe-Mn-Al-Si steels with high-manganese content demands for more research in thermo-mechanical treatment and development of micro-structure in such steels. Hot working conditions on forming the structure and course of the heat activated processes, removing the strain hardening effects, have been investigated. The chemical compositions of two high-manganese austenitic TRIP/TWIP steels containing various Mn concentrations were developed. Additionally, the steels were microalloyed by Nb and Ti in order to control the grain growth under hot-working conditions. The force-energetic parameters of hot-working were determined in continuous and multi-stage compression test performed in temperature range from 850 to 1100 °C and strain rate of 0.1, 1, 10 s-1 using the Gleeble 3800 thermo-mechanical simulator. The microstructure of investigated steels was determined in metallographic investigations using light microscope as well as X-ray diffraction. It was found that the thermo-mechanical treatment conditions have no influence on phase composition of the investigated steels. © 2012 Politechnika Wrocławska.

This study attempts to evaluate the Phytotoxkit™ as a tool for measuring the toxicity of municipal sewage sludges using 10 common plants: mustard, turnip, cress, red clover, cucumber, tomato, radish, sorrel, and spinach. The results were used to determine a germination index (GI) and a median effective concentration (EC) value for each plant. The trace metal and polycyclic aromatic hydrocarbon (PAH) contaminant content and the physical-chemical properties were examined. Most sewage sludges were characterized by an unfavorable electrical conductivity value of about 5.2 mS/cm2-1. The most abundant trace metals were zinc (Zn) at 871-1680 mg kg2-1, manganese (Mn) at 245-661 mg kg2-1, and copper (Cu) at 88.2-161.0 mg kg2-1. The lowest values were determined for cobalt (Co) at 2.9-3.8 mg kg2-1 and cadmium (Cd) at 0.7-3.7 mg kg2-1. The PAH sum was based on 10 individual compounds (USE EPA), and the PAH content ranged from 4.76 to 27.95 mg kg2-1, most of the sewage sludges showing a predomination by carcinogenic PAHs. The GI values, based on seed germination and root growth inhibition bioassays, showed increasing plant sensitivity to the tested sewage sludges in the following order: cress>turnip> mustard>sorrel>tomato>sorgo>red clover>radish>cucumber>spinach. The EC50 sewage sludge values lay in the range 31-404 g/kg of soil, and significant relationships were found for most of the plants between EC50 and the magnesium content (Mg21+: α 5 0.888-0.924, P 5 0.05), calcium content (Ca21+: α 5 0.813-0.911, P ≤ 0.05), and pH (α 5 20.913-0.948, P = 0.05). In the case of sewage sludge pollutants, significant relationships were found for trace metals such as: strontium (Sr: α 5 0.851-0.948, P ≤ 0.05), chromium (Cr: α 5 0.858, P ≤ 0.05), and nickel (Ni: α 5 0.955, P = 0.05), as well as pyrene (PAHs). © 2009 Wiley Periodicals, Inc.

The invention relates to the field of molecular biology, namely to methods of DNA extraction. The gist of the method lies in ILT virus DNA extraction from virus-containing materials via lysis and protease inactivation, using the lysing buffer including guanidine isothiocyanate followed by DNA sorption on silicon dioxide particles. The method set forth is a more efficient procedure, compared to the existing procedures for extraction of viral DNA for PCR, and has been developed for use in laboratories and research institutions engaged in PCR diagnosis of DNA-virus infections. This method of DNA extraction is easy to use, time-saving, feasible in a practical way, and suitable for preparing specimens for amplification.
