Unconventional Method for Monitoring of Waste Cooking Oil Transesterification

A technique to monitor transesterification of waste cooking oil (WCO) is presented. The technique was developed based on analogue signal from WCO, fatty acid methyl ester (FAME) and commercial palm oil (CPO). A low-pass filter design for the photodiode was used to obtain the characteristic analog signal generated by these oil samples and the signal was correlated to absorbance spectra of the oils using data from Fourier transform infrared (FTIR) equipment. A match was made between the analogue signals of the oil samples and calibrated against the FTIR spectra at 95% confidence level. Depletion of WCO during transesterification in a batch reactor correlated with the time observed for peak yield during biodiesel production. The results of the technique are discussed as a possible way to monitor transesterification process in a batch reactor.
Electrochemical Properties of High-Power Supercapacitors Using Single-Walled Carbon Nanotube Electrodes

We have investigated the key factors determining the performance of supercapacitors constructed using single-walled carbon nanotube (SWNT) electrodes. Several parameters, such as composition of the binder, annealing temperature, type of current collector, charging time, and discharging current density have been optimized for the best performance of the supercapacitor with respect to energy density and power density. We find a maximum specific capacitance of 180 F/g and a measured power density of 20 kW/kg at energy densities in the range from 7 to 6.5 Wh/kg at 0.9 V in a solution of 7.5 N KOH (the currently available supercapacitors have energy densities in the range 6‐7 Wh/kg and power density in the range 0.2‐5 kW/kg at 2.3 V in non-aqueous solvents).
Communications in Mathematical Physics Hypercommutative Operad as a Homotopy Quotient of BV

We give an explicit formula for a quasi-isomorphism between the operads Hycomm (the homology of the moduli space of stable genus 0 curves) and BV/ (the homotopy quotient of Batalin-Vilkovisky operad by the BV-operator). In other words we derive an equivalence of Hycomm-algebras and BV-algebras enhanced with a homotopy that trivializes the BV-operator. These formulas are given in terms of the Givental graphs, and are proved in two different ways. One proof uses the Givental group action, and the other proof goes through a chain of explicit formulas on resolutions of Hycomm and BV. The second approach gives, in particular, a homological explanation of the Givental group action on Hycomm-algebras.
Liberal versus neo-developmental convention to growth: why has Brazil shown a poor performance since the 1980s?

The main goal of our paper is to provide analytical arguments to explain why Brazil has not been able to restore its long-term capacity for economic growth, especially compared with its economy in the 1950-1979 period (7.3 per cent per year on average) or even with a select number of emerging economies in the 1980-2010 period(6.7 per cent per year on average, against 2.3 per cent per year on average in Brazil in the same period). We build our idea of convention to growth based on the Keynesian concept of convention. For our purposes, this concept could be briefly summarized as the way in which the set of public and private economic decisions related to different objectives, such as how much to produce and invest, how much to charge for products and services, how to finance public and private debt, how to finance research and development, and so on, are indefinitely - or at least until there is no change- carried out by the political, economic and social institutions. This analytical reference can be connected to the Neo-Schumpeterian National Innovation System (NIS) concept, which emphasizes not only institutions associated with science and technology per se, but also the complex interaction among them and other institutions. In this paper we identify two conventions to long-term growth in the last three decades in Brazil: the liberal and the neo-developmental. We show that the poor performance in the Brazilian economy in terms of real GDP growth from the 1980s on can be explained by a weak coordination between short-term macroeconomic policies and long-term industrial and technological policies. This weak coordination, in turn, can be associated with the prevalence of the liberal convention from the 1990s on, which has emphasized price stabilization to the detriment of a neo-developmental strategy whose primary goal is to sustain higher rates of growth and full employment in Brazil.
Sliding-Mode Control of Distributed Maximum Power Point Tracking Converters Featuring Overvoltage Protection

In Photovoltaic (PV) systems with Distributed Maximum Power Point Tracking (DMPPT) architecture each panel is connected to a DC/DC converter, whose outputs are connected in series to feed a grid-connected inverter. The series-connection forces the output voltage of those converters to be proportional to the converter’ output power; therefore, under mismatched conditions, the output voltage of a highly-irradiated converter may exceed the rating (safe) value, causing an overvoltage condition that could damage the converter. This paper proposes a sliding-mode controller (SMC) acting on each converter to regulate both the input and output voltages, hence avoiding the overvoltage condition under partial shading. The proposed control strategy has two operation modes: maximum power point tracking (MPPT) and Protection. In MPPT mode the SMC imposes to the PV panel the voltage reference defined by an MPPT technique. The Protection mode is activated when the output voltage reaches the safety limit, and the SMC regulates the converter’ output voltage to avoid overvoltage condition. The SMC has a bilinear sliding surface designed to provide a soft transition between both MPPT and Protection modes. The SMC analysis, parameters design and implementation are presented in detail. Moreover, simulation and experimental results illustrate the performance and applicability of the proposed solution.
Multi Objective Optimization and Multi Criterion Decision Making in Expanding Existing Standalone Energy Systems Combining Renewable Energy Sources

Hybrid Energy Systems (HESs) are becoming popular for standalone applications due to price volatility of fossil fuel resources and global concern on GHG emission. Expansion of an existing standalone Internal Combustion Generator (ICG) system while incorporating renewable energy sources is taken in to discussion in this work which converts ICG systems into a HES. In order to achieve this, a standalone HES consisting of wind turbines, SPV panels, batter bank, ICG and bi-directional converters is mathematically modeled, simulated and optimized considering power supply reliability, Levelized Energy Cost (LEC) and Renewable Energy Capacity (REC). Obtained Pareto fronts were analyzed and simple multi-criterion decision making technique is used to come up with the final system design.

ancer-cell microsurgery sing nonlinear optical ndomicroscopy in

bstract. Near-infrared laser-based microsurgery is promsing for noninvasive cancer treatment. To make it a safe echnique, a therapeutic process should be controllable nd energy efficient, which requires the cancer cells to be dentifiable and observable. In this work, for the first time e use a miniaturized nonlinear optical endomicroscope o achieve microtreatment of cancer cells labeled with old nanorods. Due to the high two-photon-excited phooluminescence of gold nanorods, HeLa cells inside a tisue phantom up to 250 m deep can be imaged by the onlinear optical endomicroscope. This facilitates microurgery of selected cancer cells by inducing instant damge through the necrosis process, or by stopping cell proiferation through the apoptosis process. The results ndicate that a combination of nonlinear endomicroscopy ith gold nanoparticles is potentially viable for minimally nvasive cancer treatment. © 2010 Society of Photo-Optical Instruentation Engineers.

Design and Development of Street Crack Detection

Automated detection of street cracks is a crucial project. In transportation preservation for driving safety assurance and detection a crack manually is an exceptionally tangled and time excessive method. So with the advance of science and generation, automated structures with intelligence have been accustomed examine cracks instead of people. For crack detection and characterization image processing is used widely. But because of the inhomogeneity along the cracks, the inference of noise with the same texture and complexity of cracks, image processing remain challenging. In this paper, we focused on the system performance and the additional features. System which has crack detection accuracy issue, false detection of crack issue, efficiency issue are solved in this system. For better accuracy in detecting crack and increasing the performance of the system we used the random forest algorithm. This system help to detect and characterized the crack and it find out crack from noise also i.e. it neglect the noise better than existing system. Similarly, proposed method find out the length of the crack width and depth of the crack from image with the help of ground truth image.
Correlates to survival of juvenile sea otters in Prince William Sound, Alaska, 1992-1993

We estimated survival of sea otters (Enhydra lutris) for 1 year post weaning during 1992-1993 in Prince William Sound (PWS), location of the 1989 Exxon Valdez oil spill. We sampled 38 pups in eastern PWS (EPWS), an unoiled area occupied by sea otters for 25 years. We compared survival between areas, sexes, and condition groups. We also examined the relation of blood parameters to survival. Survival was estimated at 0.74 in EPWS and 0.52 in WPWS. Female survival was 0.86 in EPWS and 0.64 in WPWS, whereas male survival was lower, 0.61 in EPWS and 0.44 in WPWS. Sea otters from EPWS were in better condition (mass/length) than WPWS sea otters. Pups in better condition had higher survival in EPWS but not in WPWS. Foraging success was greater in EPWS than in WPWS, consistent with either an effect of length of occupation or the effects of oil on the prey base or a combination of these effects. Area differences in blood parameters suggested liver damage in WPWS sea otters, perhaps resulting from continued exposure to oil. Thus, both length of occupation and oiling history likely influenced juvenile survival in PWS.
Gravitomagnetism due to a rotating charged body in Brans-Dicke theory

We take into account a rotating charged body, obtaining the KerrNewman-type solution in Brans-Dicke theory, assuming the weak field approximation and considering a source with low rotating motion. The solution is exhibited by using the fact that one can establish a straightforward correspondence between weak fields solutions in General Relativity and Brans-Dicke theory. Then, we calculate the gravitomagnetic field and investigate some gravitomagnetic effects, showing the electric charge contribution in each case and comparing the results with those predicted by General Relativity.

Deep Nitrate Deficit Observed in the Highly Oxygenated East/Japan Sea and Its Possible Cause

We present evidence of denitrification on the continental slopes of the Ulleung Basin (UB) and the Eastern Japan Basin (EJB) near the Tatar Strait (TtS) in the East/Japan Sea (EJS), despite its high water column dissolved oxygen concentrations. Some nutrient concentration data deviate significantly from the fitted regression line of nitrate (N) vs. phosphate (P) in deep waters, indicating a loss of nitrate in the region. The EJS has a lower N/P ratio (ca. 12.4 below 300 dbar) than a traditional Redfield ratio (16). The N/P ratio and oxygen concentration are substantially lower at several locations whose depths are close to the sediment-water interface, near TtS (500-1100 dbar) and in UB (1100-2200 dbar). The decreased nitrate concentration is smaller than the expected nitrate level (a low N/P ratio of＜12.4), and a secondary nitrite peak near the bottom of these two regions: taken collectively, both indicate the presence of denitrification in the bottom layer. It is speculated that active re-mineralization and denitrification may occur simultaneously along the rich organic matter bottom layer on the slope environment. Denitrification rates are estimated at ~3-33 μmol N m^(-2) d^(-1). Current estimates do not support the previous idea of basin-wide denitrification in EJS, although the N/P ratio is low like in other hypoxic/anoxic seas. A better understanding of the denitrification process is necessary for predicting future changes of nitrogen cycle in the well-oxygenated EJS considering the decadal-scale physical and biogeochemical changes that have occurred.
European Conference on Information Systems ( ECIS ) 2009 Objects and their participation in the interdisciplinary design and development of computer games

ERP systems are increasingly accessible to small and medium-sized enterprises (SMEs). If the potential benefits of these systems are significant, the same applies to the risk associated with their implementation. The majority of ERP studies relate to software packages supplied by large vendors such as SAP and Oracle and by smaller vendors; but until now, few have studied the adoption of ERP systems developed “in-house”. Furthermore, few studies have explicitly focused on minimizing the risk of these systems at the adoption or pre-implementation stage. Presenting a critical case study which analyzes the adoption of an in-house ERP by a SME in the agri-food industry, this article proposes and tests a process framework of ERP systems adoption, based upon a literature review and a conceptual framework centered on risk minimization. The study shows that 1) in-house ERP seems to represent a credible alternative for ERP adoption by SMEs, 2) to minimize risk at the adoption stage, a SME can proceed in a rather intuitive and unstructured manner, based however upon certain principles, policies and practices. The successful ERP implementation in this case indicates that it is not always necessary to resort to formalized project management in order to minimize implementation risk.
Trajectory of body weight of performance tested dual-purpose bulls

tant traits. The main selection criteria for meat performance of young bulls entering insemination are their own live weight and average daily gain in the period of growth performance test (110 to 365 days of age) at performance-test stations with standardised environment. Nutrition is regulated for daily gain of 1.3 kg in the test and lower value of daily gain before and after the test. Bulls are filled into stations continually all the year round; therefore contemporary groups consist of animals at different phases of growth.

Feasibility Study for the Development of a Honey-Reference Material

This paper reports a feasibility study for the development of a Honey -Reference Material (RM). Tests on the possibility to prepare the RM in different physical forms (TQ - liquid, lyophilized powder, pellets of lyophilized honey, encapsulated liquid honey) were carried out on an homogeneous batch of polyfloral honey. The analytical methods to characterize the RM for its elemental profile by TXRF, ICP-AES and ICPMS were developed, employing honey samples of different botanical origin (chestnut, black locust and polyfloral) collected in 20 different Italian Regions. Preliminary results show the feasibility to prepare a Honey -RM to be certified for the elemental profile referred both to nutritional elements and contaminants, as well as to trace elements to be used for the definition of characteristic fingerprints linked to the territorial/botanical product origin. Also the preparation of Honey -RMs in pellet form or encapsulated to be employed as Single Use -RMs turned out to be really feasible.
Development of the Control System for ERLP

ERLP will be a fully functional prototype for the Forth Generation Light Source (4GLS) a new machine to be built at Daresbury Laboratory. 4GLS will be a world-leading photon facility to enable internationally outstanding science by the ‘low-energy’ community in the UK and internationally. It will involve super-conducting linac technology with energy recovery and there will be a suite of light sources – spontaneous SR sources (i.e. traditional SR but in more intense, shorter bursts), stimulated sources (i.e. free electron lasers) and combinations of these sources with each other and with conventional lasers. The control system for ERLP is reusing some equipment and design philosophies from the Synchrotron Radiation Source (SRS) but using EPICS and VxWorks on VME64x. The status control and interlock protection system of the SRS uses close coupling of the plant equipment and its associated interlocks the latest generation uses an in-house CANbus hardware controller, this controller been integrated into the EPICS philosophy for use on ERLP. The reuse of recovered equipment has been encouraged but has resulted in increased the development time. The prototype nature of the project has presented additional challenges, which are addressed by a geographical approach to the control system design, together with flexibility designed into each sector.
Determinants of the implementation of information and communication technologies in clusters of enterprises

The implementation of Information and Communication Technologies (ICT) in enterprises organized as part of a cluster has its own specifications according to the level and type of relations between enterprises in the cluster. The purpose of this paper is to define determinants for the quality of the ICT implementation in clusters, the research goal being to define and validate the quality models of the implementation of ICT in clusters. Based on the theoretical research of clusters, the quality model for the ICT implementation has been developed and tested to the influences of the determinants of the implementation of ICT, which refer to the level of investments in ICT, quality management, the quality of processes and the level of the implementation of the ICT strategy at the level of the quality of the ICT implementation, with the confirmation of the significance of the stated hypothesis. The results of the research indicate the fact that the level of the quality of the ICT implementation could be predicted with a high accuracy, as well as the influence of the performances of enterprises and the cluster as a whole.
Towards Migration of User Profiles in the SONIC Online Social Network Federation

As of today, even though there is a strong trend of Online Social Networks (OSNs) becoming the main communication medium, OSN platforms are still mostly proprietary, closed solutions, which are not capable to seamlessly communicate with each other. The research project SONIC (SOcial Network InterConnect) proposes a holistic standard for inter-platform communication to eradicate these gaps between OSN platforms. Yet, even with such a communication architecture, users are still bound to the platform they originally signed up with. We envision a mechanism that allows users to migrate their social profiles between OSN platforms at any time without losing any data or connections. To facilitate a seamless migration of a user’s social profile from one OSN platform to another, we propose a standardized container format for social profile migration and a protocol for migration of the profile data. This allows users to move their social profiles to a new platform server without losing any data such as images or status messages. In order to uniquely identify social profiles across multiple platforms, a globally unique identifier (Global ID) is assigned to each profile. This way, social profiles, as well as references to such profiles can be kept intact when the location of the social profile has changed due to migration. To inform linked social profiles about the recently conducted migration of the profile, a Global Social Lookup System (GSLS) maintains a database of Social Records, which link the Global ID to the current profile location.

The Hot White Dwarf in the Cataclysmic Variable MV Lyrae

We have obtained the first far-ultraviolet spectrum of the nova-like cataclysmic variable MV Lyrae using the Far Ultraviolet Spectroscopic Explorer (FUSE). We also obtained contemporaneous optical light curves and spectra. All data are from a deep faint accretion state of MV Lyr. We constructed a model for the system using the BINSYN software package; results from this model include the following: (1) The white dwarf has Teff = 47,000 K, photospheric log g = 8.25, and metallicity of Z ≈ 0.3 Z☉. (2) The secondary star is cooler than 3500 K; it contributes nothing to the far-ultraviolet flux and a varying amount to the optical flux (from 10% at 5200 Å to 60% at 7800 Å). (3) The accretion disk, if present at all, contributes negligibly to the spectrum of MV Lyr. Irradiation considerations imply that the mass transfer rate is no more than 3 × 10-13 M☉ yr-1. (4) Assuming no disk is present, the model optical light curve has an amplitude approximately 50% larger than that of the sinusoidal modulation (on the orbital period) in the observed optical light curve, suggesting that the secondary star might be shaded by a nascent disk and/or have starspots near the L1 point. (5) The scaling of the model spectrum to the observed data leads to a distance of d = 505 ± 50 pc to MV Lyr.
Ionic liquid-assisted synthesis of a NiO/CNTs composite and its electrochemical capacitance

A novel solid-state method has been developed for synthesizing nickel oxide (NiO)/carbon nanotubes (CNTs) composite using an ionic liquid (IL, 1-butyl-3-methylimidazolium chloride) as the reaction medium. Ultraviolet-visible (UV-vis) absorbance spectroscopy, infrared spectroscopy (IR), and scanning electron microscopy (SEM) were employed to investigate the structure, morphology, and formation mechanism of the synthesized sample. The results demonstrated that the IL is effective for dispersing CNTs, which allows the tethering of nickel (II) ions onto the surfaces of the CNTs and facilitates the subsequent chemical deposition of NiO to obtain the NiO/CNTs composite. The electrochemical properties of the composite were determined using cyclic voltammetry and galvanostatic charge/discharge measurements in 6M KOH. Because of its unique structure, the prepared NiO/CNTs electrode exhibited good capacitive behavior and cyclability. The high specific capacitance (521 F g-1) and good rate capability (91% capacity retention at 0.5Ag-1) of the NiO/CNTs composite enable its use as a practical supercapacitor electrode material.
