Localização de Usuários Móveis Baseada em Fingerprint de Rádio Frequência: Redução de Espaço de Busca usando Parâmetros de Atraso de Onda das Redes Celulares

Radiolocation techniques based on radio frequency fingerprinting have proven to be an interesting alternative to global positioning systems. One of the attractions of the fingerprint technique is the reduction of power consumption through simplified implementations of its steps, such as the mobile user position prediction step. This work presents a modification in the search space reduction technique using the timing advance (TA), a wave delay parameter of cellular networks. Results showed that the prediction time was reduced by an average of 72.63% compared to the original technique, while the training time increased by an average of 60.18%, without compromising the accuracy of the location.

The electrochemical deposition of tin-nickel alloys and the corrosion properties of the coating

The electrodeposition of tin/nickel (65/35 wt%) is a unique coating process because of the deposition of an intermetallic phase of nickel and tin, which cannot be formed by any pyrometallurgical process. From thermodynamic calculations it can be shown that intermetallic phases can be formed through electrodeposition. The alloy has unique corrosion properties and exhibits surface passivation like stainless steel. The coating is decorative and non-allergic to the skin, can replace decorative nickel and nickel-chromium coatings in many cases and decreases the risk for allergic contact dermatitis. A number of electrochemical tests, including polarization curves, chronoamperometric studies and tribocorrosion tests have been performed to show the consequence of replacing nickel coatings with tin/nickel coatings.
Metal‐Organic Frameworks for Carbon Dioxide Capture and Methane Storage

In the global transition to a sustainable low‐carbon economy, CO2 capture and storage technology still plays a critical role for deep emission reduction, particularly for the stationary sources in power generation and industry. However, for small and mobile emission sources in transportation, CO2 capture is not suitable and it is more practical to use relatively clean energy, such as natural gas. In these two low‐carbon energy technologies, designing highly selective sorbents is one of the key and most challenging steps. Toward this end, metal‐organic frameworks (MOFs) have received continuously intensive attention in the past decades for their highly porous and diversified structures. In this review, the recent progress in developing MOFs for selective CO2 capture from post‐combustion flue gas and CH4 storage for vehicle applications are summarized. For CO2 capture, several promising strategies being used to improve CO2 adsorption uptake at low pressures are highlighted and compared. In addition, the conventional and novel regeneration techniques for MOFs are also discussed. In the case of CH4 storage, the flexible and rigid MOFs, whose CH4 storage capacity is close to the target set by U.S. Department of Energy are particularly emphasized. Finally, the challenge of using MOFs for CH4 storage is discussed.
CURRENT THERAPEUTIC EVIDENCE BASED APPROACHES TO PATIENTS WITH FALCIPARUM AND NON-FALCIPARUM MALARIA

Malaria is a major concern for international health authorities and potentially lifethreatening disease because of millions of people suffer every year in the world dueto a parasite of the Plasmodium genus transmitted by an infective female Anophelesmosquito vector. Due to the complexity of the parasite biology and genetics, there iscurrently no vaccine. Individuals with malaria may present with fever and a wide rangeof symptoms. The second half of the 20th century saw the emergence of strains of malariaparasites (mainly P.falciparum) resistant to chloroquine, which was the most commonlyused drug for treatment of the disease. While resistance spread geographically, it alsoevolved chemically including to other antimalarial drugs like quinine, sulfadoxine,pyremethamine, and proguanil.The aim of research. To describe modern aspects of etiology and epidemiology ofmalaria, caused by different species of parasite; and to highlight clinical peculiaritieswith analysis of the best evidence based recommendations of its chemotherapy.Methods. We had used scientific paper searching in Scopus, Cochrane databases, andNCBI library (Pubmed) by key words as “malignant tertian malaria treatment”, “benigntertian malaria”, benign quartana malaria”, “malaria and pregnancy”, “resistance toantimalarials”. Results. Nowadays there are six known genetically different species of Plasmodiumcaused malaria disease in human worldwide. This vector-borne infection may transmitvia mosquito, blood products, a liver transplantation and through placenta from pregnantto fetus. If suspected any malaria type, promptly therapy should be suggest accountedtravel anamnesis and WHO as well as national recommendations. Therapy containedarthemisin in combination with lumefantrine or mefloquine is better and more effectivethan monotherapy. In case of P.ovale and P.vivax primaquine phosphate is essential topreclude recrudescences.Conclusions. Ukraine is the eastern European country with annual morbidity becauseof exotic cases connected with travels and employment. In case of fever, chills, sweats,hepatosplenomegaly patient should be tested for parasite presence by methods ofparasitoscopy of thick drop and thin smear of blood. Chemoprophylaxis within allduration in endemic country by available antimalarial should be obligatory beforeplanning to subtropical and tropical regions.
Bibliometric analysis of research trends and focuses of plant functional traits

Plant functional traits (PFTs) are a research focus in ecology, and an illustration of the research focuses and development of this field that can serve as a reference for future related research. Through the retrieval of relevant papers on PFTs published from 1998 to 2017 from the Web of Science and extracted literature information, this study applied a bibliometric analysis to analyze information on 1938 papers to reveal the research focuses, development patterns and potential problems of this field. The results show the following: research on PFTs has undergone three stages from 1998-2017: slow development (1998-2002), steady growth (2003-2009) and rapid development (2010-2017). The scholar with the largest number of published papers is Reich PB (56 papers) followed by Lavorel S (51 papers) and Garnier E (48 papers). The country with the most published papers is the United States (579 papers), followed by France (302 papers) and China (279 papers). The research institution with the largest number of published papers is the Chinese Academy of Sciences (161 papers), followed by the French National Institute for Agricultural Research (94 papers) and the University of Minnesota (87 papers). The Journal of Vegetation Science, Journal of Ecology and New Phytologist are the three journals with the most published papers. A keyword analysis shows that research focuses of this field include the trade-off between functional traits, the relationship between PFTs and community assembly, and the impact of PFTs on responses to global climate change.
A High-Level Synthesis Methodology for Energy and Reliability-Oriented Designs

Shrinking technology sizes of the CMOS circuits makes it possible to place more transistors on a single chip at each technology generation. On the other hand, circuits become more vulnerable to radiation effects due to lower supply and threshold voltage levels; thus, the number of transient faults in circuits tends to increase. Moreover, energy reduction techniques also negatively affect the reliability of circuits. Traditional high-level synthesis (HLS) methods usually consider only area and latency along with either energy or reliability. Especially the effect of using different voltage levels on reliability is completely ignored by previous studies. In this article, we present two new HLS methods for application-specific integrated circuit (ASIC) design under area and timing constraints with the objectives of low energy consumption and high reliability. For the mapping and scheduling steps of HLS, we propose integer linear programming (ILP) and genetic algorithm (GA)-based optimization methods. While ILP provides the optimum results, the CPU time increases exponentially with the number of application nodes. On the other hand, GA-based metaheuristic is faster and determines optimum or near-optimum results in shorter times than ILP. Additionally, we use a selective duplication method to further improve the overall reliability.
L1-Norm Sparse 2-D Phase Unwrapping Algorithm Based on Reliable Redundant Network

Multitemporal interferometric synthetic aperture radar (InSAR) technology has become an important tool for digital elevation model (DEM) generation and surface deformation monitoring. The prerequisite is to obtain the correct unwrapped phase of the interferograms. However, it is still challenging to obtain reliable results by traditional 2-D phase unwrapping (PU) algorithms and even 3-D PU algorithms, when the phase continuity assumption fails due to large deformation gradients or abrupt topographic changes. This letter proposes an ${L}^{ {1}}$ -norm sparse 2-D PU algorithm based on reliable redundant network in the phase discontinuous region, which is obtained by implementing ambiguity detector on free network within a given distance. Experiment on real synthetic aperture radar (SAR) interferograms covering urban tall buildings verified that the algorithm can obtain more reliable results in phase discontinuous regions than traditional PU algorithms.
Passive, non-systematic search as an alternative to systematic search in opportunity discovery

This paper summarizes the results of a multiple-case study conducted to shed light into the question of how business opportunities are recognized by examining two theoretical propositions related to two topics: 1) the role of prior knowledge in the discovery of opportunities, and 2) whether opportunities are noticed without deliberate search or can be the object of a constrained, systematic search. We studied five Spanish companies and eight business opportunities. All the opportunities of the multiple-case study were recognized thanks to the prior knowledge of the entrepreneurs. In addition, the entrepreneurs only discovered opportunities related to their prior knowledge. None of the opportunities was discovered by noticing without search, as the alertness perspective contends. Some of them were the result of a systematic search constrained to the entrepreneur’s prior knowledge, but most of them were discovered by searching passively and non-systematically within the knowledge domain of the entrepreneur. This result suggests the passive, non-systematic search as an alternative to the systematic search.
The Social Uncanniness of Robotic Companions

Social robots offer a promise of relatedness without the limitations of human ability and availability. However, the idea of robotic companionship can also cause unease, a phenomenon I coin the Social Uncanniness of robotic companions. This sense of unease could be attributed to the fact that social robots touch on deeply rooted psychological concerns, including our need to be unique individuals that cannot easily be replaced or replicated; our ambivalent relationship with natural decay, including our own; and a fear that by relating to robots we may lose our ability to relate appropriately to other humans.
Wire Arc Additive Manufacturing Perspectives and Recent Developments

The outstanding performance of producing complex three dimensional moulded components, which could be difficult or impossible to accomplish through traditional production processes. Additive processing in recent years has revolutionised the processing paradigm. Due to the high deposition speeds, which are substantially higher than powdered techniques, the wire and arc additive manufacturing (WAAM) is distinct among various additive manufacturing techniques that are suitable for producing large metal components. WAAM’s efficiency is growing rapidly, and thus substantial study is ongoing. This research work will include an overview of the greatest advances in WAAM, outlining the innovations and variants in processes to monitor the microstructure, mechanical properties and defect production in the as-built components along with the most important technological materials used, and the variants of WAAM.

Concluiu-se que as diferencas entre as redes sao relativas a maturidade, a amplitude da rede federal e a similaridade dos atores da rede estadual, mesmo que ambos sejam fenomenos recentes. Como proposta para futuras pesquisas, sugere-se estudo longitudinal que acompanhe as redes no seu processo de institucionalizacao.
Managing Climate Change: The Role of Multi-Stakeholder Partnerships in Building Climate Resilience in Sub-Saharan Africa

Research increasingly suggests that climate change has intensified the frequency of droughts, floods, and other environmental disasters across sub-Saharan Africa. In response to the resulting array of climateinduced challenges, various stakeholders are working collectively to build climate resilience in rural and urban communities and trans-continentally. This paper examines key climate resilience-building projects that have been implemented across sub-Saharan Africa through multi-stakeholder partnerships. It uses a vulnerabilities assessment approach to examine the strategic value of these projects in managing the mitigation of climate shocks and long-term environmental changes. There are still many challenges to building climate resilience in the region, but through multi-stakeholder partnerships, sub-Saharan African nations are expanding their capacity to pool resources and build collective action aimed at financing and scaling up innovative climate solutions. This article contributes to ongoing interdisciplinary academic, management, and policy discourses on global climate adaptation focused on populations and landscapes most at risk.
Shape Evolution of Monolayer MoS2 Crystals Grown by Chemical Vapor Deposition

Atmospheric-pressure chemical vapor deposition (CVD) is used to grow monolayer MoS2 two-dimensional crystals at elevated temperatures on silicon substrates with a 300 nm oxide layer. Our CVD reaction is hydrogen free, with the sulfur precursor placed in a furnace separate from the MoO3 precursor to individually control their heating profiles and provide greater flexibility in the growth recipe. We intentionally establish a sharp gradient of MoO3 precursor concentration on the growth substrate to explore its sensitivity to the resultant MoS2 domain growth within a relatively uniform temperature range. We find that the shape of MoS2 domains is highly dependent upon the spatial location on the silicon substrate, with variation from triangular to hexagonal geometries. The shape change of domains is attributed to local changes in the Mo:S ratio of precursors (1:>2, 1:2, and 1:<2) and its influence on the kinetic growth dynamics of edges. These results improve our understanding of the factors that influence the.
Actualización del catastro de ensamble de moluscos costero-marinos del archipiélago Diego Ramírez (56°31’S), Chile: Un refugio para la economía sustentable y conservación subantártica

The Diego Ramirez archipelago is the last point of the South-America continent, located in the Drake Passage 111 km SW of Cape Horn. Due to its difficult access, information on the marine biodiversity that inhabits its coasts is still limited. This study presents the first report of the assemblage of coastal marine mollusks in this archipelago. Samples were collected during an expedition to Gonzalo Island during the spring of 2016. During the low tide an exhaustive inspection and collection of mollusks was carried out from the upper intertidal zone to 1 m depth. Records of these collections were complemented with reports from previous expeditions. A total 51 mollusk taxa were identified. Among the identified taxa, 42 mollusk species were new to Diego Ramirez Islands. This work is an updated list record of mollusks of the Diego Ramirez archipelago. It is important to continue investigating and monitoring this archipelago which corresponds to the southern limit of the Magellanic Province and the last South American rocky remnants that face the Drake passage.

Idvc Based Hysteresis Controller For Three-Phase Induction Motor Drive

Induction Motor is the most commonly used motor in industrial applications due to its characteristics like self-starting, reliable and easy speed control. The objective of the proposed system is to provide efficient speed control with lesser current harmonics. The Indirect Vector Control (IVDC) method is been presented for speed control of induction motor due to its high dynamic and low drift property. Though there were many classical methods for speed control like Ward-Leonard method etc.; in later years, power electronics circuits were preferred due to its high efficiency, reliability and accuracy. But the presence of static converter in drive circuits results in harmonics, giving in high feedback complexity. Therefore, the Hysteresis controller with conventional Proportional Integral and Differential (PID) control for speed and PI controller for flux is used to control the current harmonics at the point of common coupling. The simulation for speed control in squirrel-cage induction motor is carried out using the MATLAB/Simulink and the parameters like torque, speed, current and Total Harmonic Distortion are analyzed to show optimal response of drive system.
Are Key Audit Matter Disclosures Useful in Assessing the Financial Distress Level of a Firm?

This study examines the usefulness of new expanded audit report key audit matters (KAM) disclosures in assessing firm financial distress. Using KAM disclosures from a manually-collected sample of Premium listed firms in the U.K. for 2013 to 2018, we explore the association between the number, level (entity versus account), financial category (profitability, liquidity, or solvency), and nature (individual type) of auditor disclosed KAMs and firm financial distress. We find evidence that the greater the number of KAMs disclosed on a firm’s audit opinion, the higher the financial distress level of the firm. Results also show an association between the level and nature of KAM(s) disclosed by an auditor. Specifically, we find evidence that certain entity-level (e.g. going concern, restructuring and discontinued operations, and mergers and acquisitions) and individual account-level (e.g. revenue and management estimates) KAMs, as well as account-level KAMs with primary impact on a firm’s profitability and solvency, are more likely to be disclosed than others when firms are in financial distress. Our findings also suggest that KAMs have predictive ability in assessing the subsequent period financial distress of a firm. In all, the results provide evidence of a significant relation between KAM disclosures and firm financial distress levels, and in so doing, show that expanded auditor report regulation can help financial statement users assess one of the main risks associated with a firm - the risk of failure.
STUDY OF LIPID PROFILE, SERUM MAGNESIUM AND BLOOD GLUCOSE IN HYPERTENSION

An attempt was made to study the role of lipid profile serum Mg+2, and blood glucose in hypertension individuals. Moreover, all the parameters are analyzed biochemically. In about 80 samples (50cases and 30 controls) and it is observed that dyslipidemia is seen in Hypertensive individuals with no change in HDL concentration. There is no correlation of serum magnesium in hypertensive cases with controls. It has been observed that serum magnesium of hypertensive cases is slightly higher than that of normal individuals. Fasting blood glucose of hypertensive cases (101.62mg/dl ±33.78) is higher than that of Controls (82.46 mg/dl±10.8). This increase is statistically significant (p<0.001). But this increase may be due to the presence 12% diabetic cases present in the cases. Even then, there is a tendency of developing impaired glucose tolerance in hypertensive subjects. The blood pressure is noted separately as systolic blood pressure and diastolic blood pressures. The systolic blood pressure was more significant than the diastolic blood pressure with increasing age groups.
