Thermodynamic mechanism of self-heat recuperative heat circulation of vapour system

Self-Heat Recuperation Technology has recently been proved to be an effective method to cut the huge energy consumption in the chemical industry. In the present paper, the thermodynamic mechanism of the self-heat recuperative heat circulation of the vapour system without chemical reaction is studied in terms of exergy analysis using process module, temperature-entropy and energy conversion diagrams. The self-heat recuperative thermal vapour cycle process was modularized by combining four types of thermodynamic elementary process modules, namely isobaric heating and cooling process modules (heat receiver (HR) and heat transmitter (HT)) and isentropic compression and expansion process modules (work receiver (WR) and work transmitter (WT)), and a heat exchange process module (heat exchanger (HX)). In the four types of thermodynamic elementary process modules (HR, HT, WR, WT), both exergy and anergy are conserved. It is only in the heat exchange process module (HX) that exergy destruction takes place and the destructed exergy transforms into the same amount of anergy due to irreversibility of heat transfer. In the self-heat exchange process, the process fluid undergoes temperature change and phase transition. Therefore, the self-heat exchange process should be divided into three stages, namely the self-heat exchange of the liquid sensible heat, the self-heat exchange of the latent heat, the self-heat exchange of the vapour sensible heat. Correspondingly three HXs are necessary, and only in these three HXs do all the exergy destructions of the self-heat recuperative thermal vapour cycle process take place. The work provided as the minimum work required for the self-heat recuperative heat circulation of the vapour system by compressing the process fluid in the vapour phase through one WR, i.e. work input, equals the sum of the exergy required to compensate for the three exergy destructions of the three HXs and the exergy required to discard waste heat to the environment. The work input eventually converts to the waste heat, i.e. heat output, the exergy of which is the exergy required to discard the waste heat to the environment and the anergy of which results from the three exergy destructions of the three HXs.
PENGARUH VARIASI BERAT FOAMING AGENT CaH2 TERHADAP KARAKTERISTIK PADUAN Mg-Ca-Zn METAL SELULAR BERBASIS SISTEM Mg-Zn-CaH2

THE EFFECTS OF FOAMING AGENT CONTENT CaH2 ON THE CHARACTERISTIC OF METAL CELLULAR Mg-Ca-Zn ALLOYS BASED ON Mg-Zn-CaH2 SYSTEM. In this study, cellular metal with the open-cell structure of Mg-Ca-Zn alloy based on Mg-CaH2-Zn system was prepared and investigated. The addition of CaH2 was intended to trigger the release of hydrogen gas from CaH2 of the alloy powder particles so as to encourage the formation of pores. Alloy composition was selected by -2% by weight Mg Zn 1.2% by weight of CaH2; and Mg -2 wt% Zn 10% by weight of CaH2. The results of the alloy powder after milling and compacting were tested by Differential Thermal Analysis (DTA), while the results of sintered green-compacts were characterized by XRD (X-ray diffraction) and microstructure observation using SEM-EDS (scanning electron microscopy-energy dispersive spectroscopy). From the analysis using XRD, the process of mechanically mixing powders of Mg-Ca-Zn-Mg CaH2 produced elemental phase of Zn phase, Mg phase (HCP) and binary phase of Mg2Ca besides the ternary Mg-Ca-Zn.
DEVELOPMENT OF ANODIC STRIPPING VOLTAMMETRY FOR THE DETERMINATION OF PALLADIUM IN HIGH LEVEL NUCLEAR WASTE

Deposition potential, deposition time, square wave frequency, rotation speed of the rotating disc electrode, and palladium concentration were studied on a Glassy Carbon Electrode (GCE) in 0.01M HCl for the determination of palladium in High Level Nuclear Waste (HLNW) by anodic stripping voltammetry. Experimental conditions were optimized for the determination of palladium at two different, 10 -8 and 10 -7 M, levels. Error and standard deviation of this method were under 1% for all palladium standard solutions. The developed technique was successfully applied as a subsidiary method for the determination of palladium in simulated high level nuclear waste with very good precision and high accuracy (under 1 % error and standard deviation).
The Case for HPM-Based Baugh-Wooley Multipliers

The modified-Booth algorithm is extensively used for high-speed multiplier circuits. Once, when array multipliers were used, the reduced number of generated partial products significantly improved multiplier performance. In designs based on reduction trees with logarithmic logic depth, however, the reduced number of partial products has a limited impact on overall performance. The Baugh-Wooley algorithm is a different scheme for signed multiplication, but is not so widely adopted because it may be complicated to deploy on irregular reduction trees. We use the Baugh-Wooley algorithm in our High Performance Multiplier (HPM) tree, which combines a regular layout with a logarithmic logic depth. We show for a range of operator bit-widths that, when implemented in 130-nm and 65-nm process technologies, the Baugh-Wooley multipliers exhibit comparable delay, less power dissipation and smaller area foot-print than modified-Booth multipliers.
Retargetable User Interface for Health Effects of Air Quality

Continuous advances in mobile technology has enabled the use of smartphones in healthcare assistance targeted at vulnerable users such as older adults. However, difficulties in interacting with information and communication technologies affect a wider percentage of the population around the globe in both the developed and developing nations. This project describes the design and evaluation process of the User Interface (UI) for a healthcare mobile application, AirRespeck, designed to calculate the dosage of air pollution inhaled during physical activity. The UI aims to be retargetable to users from different age groups. The application will include various configuration options in order to allow the UI to be customized according to the user’s needs and preferences. The results and findings of this project are expected to contribute to the broader research community when designing interfaces for smartphones.
Bidirectional Modular Multilevel DC/DCConverter with Wide Range of Control

In this paper we describe about the utilization of braking energy during regenerative braking operation by using different cascaded multilevel topologies by interfacing of the super capacitor to dc bus in the regenerative applications. Energy storage plays an important role in the high power application. Super capacitors are chosen because they have high density, efficiency and long life cycles. The modular multilevel dc/dc converter (MMC) is used to reduce voltage and increase frequency across the inductor in order to reduce the weight and size of the inductor with phase shifting modulation. The circuit is used as a bi-directional power source and converter. The super capacitors are used for voltage balancing for output current control. The proposed system is plays an important role in hybrid and electric vehicle applications
Fitting Phase-type Distributions via the EM Algorithm

Estimation from sample data and density approximation with phase-type distribu- tions are considered. Maximum likelihood estimation via the EM algorithm is discussed and performed for some data sets. An extended EM algorithm is used to minimize the information divergence (maximize the relative entropy) in the density approximation case. Fits to Weibull, log normal, and Erlang distributions are used as illustrations of the latter.
An efficient method for detection of inspiration phase of respiration in thermal imaging

Respiration rate and the time duration between successive respiration cycles are two important parameters required for detection of apnea disorders during a polysomnograph test. Conventional methods use thermistors and respiration belts to measure these parameters. These however cause patient discomfort and also tether the patient to the bed. Thermal imaging is proposed in literature for non-contact measurement of respiration rate, wherein the inspiration and expiration of the patient can be visually monitored as temperature variations from his thermal images. In this paper, a segmentation approach is proposed to accurately localize the low temperature region that occurs near the nostrils during inhalation.
Bounding quantum gate error rate based on reported average fidelity

Remarkable experimental advances in quantum computing are exemplified by recent announcements of impressive average gate fidelities exceeding 99.9% for single-qubit gates and 99% for two-qubit gates. Although these high numbers engender optimism that fault-tolerant quantum computing is within reach, the connection of average gate fidelity with fault-tolerance requirements is not direct. Here we use reported average gate fidelity to determine an upper bound on the quantum-gate error rate, which is the appropriate metric for assessing progress towards fault-tolerant quantum computation, and we demonstrate that this bound is asymptotically tight for general noise. Although this bound is unlikely to be saturated by experimental noise, we demonstrate using explicit examples that the bound indicates a realistic deviation between the true error rate and the reported average fidelity. We introduce the Pauli distance as a measure of this deviation, and we show that knowledge of the Pauli distance enables tighter estimates of the error rate of quantum gates.
Enhancement and Bias Removal of Multiframe Optical Coherence Tomography Images: an Iterative Approach via Adaptive Bilateral Filtering

Optical coherence tomography (OCT) has continually evolved and expanded as one of the most valuable routine tests in ophthalmology. However, noise (speckle) in the acquired images causes visual quality degradation of OCT images and makes it difficult to distinguish structural details in the acquired image. In this article, an iterative approach based on bilateral filtering is proposed for speckle reduction in multiframe OCT data. Gamma noise model is assumed for the observed OCT image. First, the adaptive version of the conventional bilateral filter is applied to ameliotate the multiframe OCT data and then the bias due to noise is reduced from each of the filtered frames. ∗Corresponding author URL: spvnitt@gmail.com (PV Sudeep) Preprint submitted to Computers in Biology and Medicine February 1, 2016 These unbiased, filtered single frames are then refined using an iterative approach. Finally, these refined single frames are averaged to produce the enhanced OCT image. Experimental results on phantom images and real OCT retinal images demonstrate the effectiveness of the proposed filter.
The Factors Affecting the Trustworthiness of Customers towards the Usage of Internet Banking in Malaysia

The number of internet users in Malaysia is significantly high in comparison with other countries. It is reported that the number of internet users who were born in the year 2000 and above is almost near 70% in Malaysia. In 2015, the Malaysian internet users has exceeded to more than 19 million users. Therefore, the amount of banks that are implementing internet services to their customer is to be roughly 30. Meanwhile, there are only 13 banks in Malaysia that offers mobile banking services to its customers. Although there has been a rapid distribution of mobile internet by banks, internet banking services is still not fully adopted by banks. The objective of the study is to study about the factor affecting the trustworthiness of customers towards the usage of internet banking in Malaysia. This research is about the trustworthiness of customers towards the usage of internet banking. There are a few variables of factors that affect the trustworthiness of customers towards the usage of internet banking and it is clearly explained and elaborated. The factors are competency, security, integrity performance and shared values. Next, the methodology quantitative approach has used in this research whereby 200 respondents were sampled by the population from using the simple random taking. Employed the SPSS Version 22.0, the multiple regression analysis and correlation analysis was created out to test the four hypothesis for this research. Moreover, this research will be conducted in Kota Damansara, Malaysia.
Chapter 14 Sugarcane Bagasse As Potentially Low-Cost Biosorbent

Sugarcane bagasse (SB) is one of the major residues obtained from agriculture, every year millions of tons of SB have been produced by the sugarcane agribusiness. This abundant residue has been showed potential as biosorbent in wastewater treatment. SB, in nature or chemically modified, has been widely reported as a promising sorbent for the removal of dyes or heavy metals from aqueous medium. The application of SB in oil sorption is rarer, especially for the treatment of used motor oil wastewater. However, in this chapter, we show that this material has good oil sorption capacity when compared to other commercial and natural sorbents. This study evaluates the effect of several coupling agents over SB in used motor oil sorption as well as the influence of surfactant in this process.
Networked Fandom: Applying Systems Theory to Sport Twitter Analysis

The purpose of this study was to employ systems theory to analyze the social network of a Big Ten football team’s Twitter community. An identifiable network was found among the observed actors (N = 139), with fan accounts composing the largest percentage of the network. The number of observed reciprocal interactions was low, only 11.8% of the interactions and only 21.5% of the nodes. Traditionalmedia accounts frequently interacted with other media accounts, while fans interacted primarily with other fans. Overall, nontraditional-media accounts’ users were most focused on interactivity. Team-related accounts were almost nonexistent in the interactive network. A systems-theory-based network was found in terms of input, transformation, and output components. The feedback loop was the weak link in the network, indicating a possible lack of importance of direct feedback in Twitter social networks.
Analysis of winter and summer warming rates in gridded temperature time series

The Intergovernmental Panel on Climate Change (IPCC) stated in its 1995 report that 'the balance of evidence suggests a discernible human influence on global c h a t e ' . The observed nearsurface warming which has occurred in the winter season over the mid-to-hlgh latitudes of the Northern Hemispheric continental areas is used as empirical support for numerical model sirnulations which suggest a similar pattern of temperature change to occur under conditions of increasing atmospheric carbon dioxide levels. In this work, we investigate, in detail, the seasonal pattern of temperature change as derived from the 2 gridded temperature departure datasets-the IPCC land-based data since 1946. and the MSU (microwave sounding units) satellite-based dataset since 1979. We find that the pattern of temperature trend differentials between winter and summer seasons has not remained constant over the last 50 yr, and over the last 2 decades is in less agreement with numerical model simulations. We find a negative correlation between relative winter warming and average winter temperature, which means that winter temperatures are warming the most in colder locations.
Voluntary Action Of A Firm On Enviroment Management: An Empirical Assessment On Sri Lankan Food Processing Firms’ Response To The Private And Regulatory Incentives

The effect of a set of private/market (i.e. financial implications, internal efficiency, market response) and public/non-market (i.e. government regulation, judiciary/legal system) incentives for a firm to act voluntarily on environmental quality is examined. It uses the levels of adoption of five solid waste management practices [SWMPs], namely: (1) 3R system; (2) Composting; (3) Good manufacturing practices; (4) Biogas unit, and (5) ISO 14000 by food processing sector in Sri Lanka in response to the prevalence of each incentive at the firm as the case. The data collected from 325 firms through in-depth interviews and site inspections and supported by a validated structured questionnaire were analyzed using the principles of Structural Equation Modeling. The “Analysis of Moment Structures” (AMOS) software was used to establish the relationships between the levels of adoption of SWMPs and the strength of each incentive. The results show that firms‟ response to environment is relatively low, i.e. 49.2% did not adopt a single practice, while only 28%, 12%, 7.4%, 3.1% and 0.3%, respectively, have adopted 1, 2, 3, 4 or all practices. Firms tend to adopt a higher number of SWMPs as the relative strength of an each incentive perceived by the decision maker of firm gets increases. Firms put a higher weight on the impact on regulation and legal system than the private incentives and the firm size has a substantial impact on its response to the environment. The results highlight the importance of bringing the current public regulatory regimes in developing countries like Sri Lanka towards co-regulation, which is practiced by developed countries like Australia and Canada to facilitate businesses to come up with own solutions for environmental and food quality, as the outcome of this analysis points out that firms‟ compliance to the recommended SWMP was not triggered satisfactorily by the private/voluntary action.
Secure UAV Communication With Cooperative Jamming and Trajectory Control

This letter presents a new cooperative jamming approach to secure the unmanned aerial vehicle (UAV) communication by leveraging jamming from other nearby UAVs to defend against the eavesdropping. In particular, we consider a two-UAV scenario when one UAV transmitter delivers the confidential information to a ground node (GN), and the other UAV jammer cooperatively sends the artificial noise to confuse the ground eavesdropper for protecting the confidentiality of the data transmission. By exploiting the fully controllable mobility, the two UAVs can adaptively adjust their locations over time (a.k.a. trajectories) to facilitate the secure communication and cooperative jamming. We assume that the two UAVs perfectly know the GN’s location and partially know the eavesdropper’s location a priori. Under this setup, we maximize the average secrecy rate from the UAV transmitter to the GN over one particular time period, by optimizing the UAVs’ trajectories, jointly with their communicating/jamming power allocations. Although the formulated problem is non-convex, we propose an efficient solution by applying the techniques of alternating optimization and successive convex approximation.
DE CANA-DE-AÇÚCAR ( 1 )

A cultura da cana-de-açúcar é de extrema importância no cenário agrícola nacional. No entanto, pouco se sabe sobre a estruturação das comunidades microbianas associadas aos solos e às rizosferas de tais plantas. O objetivo deste trabalho foi avaliar a estrutura e diversidade das comunidades de bactérias associadas ao solo e à rizosfera de seis variedades de cana-de-açúcar cultivadas no Estado de São Paulo (Brasil). As análises foram realizadas com base em métodos independentes de cultivo, em que a técnica de PCR-DGGE revelou alterações na rizosfera para os grupos de bactérias totais e também para os grupos de Alphaproteobacteria e Betaproteobacteria. Após essa análise, quatro amostras (três de rizosfera e uma de solo) foram usadas para o sequenciamento da região V6 do gene 16S DNAr na plataforma Ion TorrentTM. Essa análise gerou um total de 95.812 sequências, dentro das quais houve a predominância das afiliadas aos filos Actinobacteria, Proteobacteria e Acidobateria. Os resultados revelaram que as comunidades bacterianas na rizosfera são distintas daquelas encontradas no solo. Foi possível ainda observar efeito diferencial de plantas das variedades. Alguns grupos bacterianos apresentaram menor frequência na rizosfera (Acidobacteria), enquanto outros se mostraram fortemente estimulados pela presença das raízes, comumente para todas as variedades (Betaproteobacteria, Nitrospora e Chloroflexi), ou em respostas variedade-específicas (Bacilli e Sphingobacteria).
Urban Livestock Production in Cambodia Socio-Economic Benefits and Public Health Hazards

Djurhållning kan utgöra en viktig inkomstkälla som bidrar till förbättrad levnadsstandard och en väg ut ur fattigdom för många invånare i städer. Att hålla djur inom och runt omkring städer kan dock medföra ökade föroreningar och en ökad förekomst av sjukdomar som sprids mellan djur och människor (zoonoser). Syftet med den här avhandlingen var att tillhandahålla vetenskaplig information om olika socioekonomiska fördelar och hälsorisker associerade med hållning av grisar i städer och stadsnära områden i ett lägre medelinkomstland som Kambodja. Intervjuer genomfördes i hushåll i Phnom Penh och gödselprover togs från deras grisar för detektering av zoonotiska patogener och för antibiotikaresistensanalys. Majoriteten av hushållen (60 %) ansåg att inkomsten från grisarna var en av hushållets viktigaste inkomstkällor. Sjukdomar och låga intäkter från slakt ansågs vara de största begränsningarna för hushållets djurhållning. Ingen av respondenterna nämnde dock några farhågor om potentiella hälsorisker. Det fanns en tydlig skillnad mellan djurarter med avseende på gödselhanteringen, där grisgödsel vanligen dumpades i miljön (46 %) medan kogödsel användes som gödningsmedel (66 %) (P < 0,001). Dumpning av grisgödsel var vanligare bland hushåll med lägre socioekonomisk ställning (P < 0,001) och bland hushåll som inte hade tillgång till jordbruksmark (P < 0,001). Användningen av antibiotika baserades till stor del på djurhållarnas egna omdömen och 66 % justerade vanligtvis själva både dosering och behandlingstid. Runt 45 % hade inte hört talas om antibiotikaresistens. Höga resistensnivåer påvisades hos tarmbakterien Escherichia coli, varav mot flera antibiotika som anses vara viktiga för humansjukvården, och multiresistens återfanns i 79 % av proverna. Antibiotikaresistens var vanligare på gårdar som behandlade grisarna i förebyggande syfte och på gårdar som behandlade hela gruppen eller besättningen vid tecken på sjukdom. Den här avhandlingen visar att, även om grisproduktion ansågs vara en viktig inkomstkälla bland djurhållarna, så kunde den bidra till både miljöföroreningar och ökade hälsorisker för andra invånare. Investeringar i sjukdomsförebyggande åtgärder och förbättringar inom gödselhanteringen är nödvändigt för att stadsnära djurhållning ska kunna bedrivas på ett säkert sätt i länder som Kambodja.
