Performance Comparison and Analysis of Routing Strategies in Mobile Ad Hoc Networks

The performance of routing protocols in mobile ad hoc network (MANET) always attracts many attentions. As many previous works have shown, routing performance is greatly dependent to the availability and stability of wireless links. Although there are some studies reported to evaluate the performance of routing protocols in MANET, little work is done for the system overall performance, which is generally referred to as the network throughput and the end-to-end delay. This paper evaluates the routing strategies of the three routing protocols (AODV, OLSR and SRMP) and compares their performance under two different mobility models. We study those protocols under varying metrics such as node mobility and network size. Our objective is to provide a qualitative assessment of overall performance of the routing strategies in different mobility model. The results illustrate that the routing strategies behind the three protocols affect their performance deeply. Meanwhile, different from previous results in the literature, the result shows that it is the combination of routing strategies behind the routing protocols to determine the performance in given scenarios.

On the feasibility of automated market making by a programmed specialist

Securities trading is accomplished through the execution of orders. Admissible orders (e.g., market orders, limit orders) give rise to discontinuous aggregate demand functions, composed of many "steps. " Demand smoothing, or the balancing of excesses due to such discontinuities via intervention, is one of the most basic functions that could be assigned to a "specialist. " When the specialist's "affirmative obligation" is fully specified, his or her activity can in principle be automated. This paper is an attempt to assess, via simulation, some of the ramifications of using a "programmed specialist," whose automated market making is limited to demand smoothing. A number of alternative rules of operation are simulated. Several of the rules performed well, especially the extremely simple rule that calls for the (computerized) specialist to minimize new absolute share holdings in each security at each tradingpoint via "total" (as opposed to "locaI") demand smoothing. Our results indicate that the underlying costs of demand smoothing are on the order of a fraction of a penny per share traded even in relatively thin markets. THE FUNCTION OF THE specialist as a "designated market maker" has traditionally been taken for granted by market participants while being practically ignored by financial and economic theory. Recently, this function has become the subject of' increasing scrutiny. Current discussions in connection with the possible reorganization of the exchanges into a National Securities Market have raised serious questions concerning the roles (if any) that should be assigned to specialists in this market, especially if the order clearing mechanism is to be highly automated. ' On the theoretical side, the specialist's function has become one of the focal points in an emerging new field of financial theory which concentrates
2DSpotDB: A Database for the Annotated Two-dimensional Polyacrylamide Gel Electrophoresis of Pathogen Proteins

The biological interpretation of two-dimensional (2D) gel electrophoresis experiments is a key step toward understanding the functions of biological systems. We here present a web-based integrated database, called 2DSpotDB, for the management of proteome data derived from several pathogens. The 2DSpotDB was established as a part of the management of a pathogen proteome project at the Korea National Institute of Health. The goals of the 2DSpotDB implementation are to store and define important pathogen genes, retrieve information obtained by 2D polyacrylamide gel electrophoresis and mass spectrometry, and create an integrated system to provide pathogen proteome information for biological scientists. This database currently contains 14 gels and information on 387 protein spots, among which 329 proteins were identified and annotated.
Aerial Access and Backhaul in mmWave B5G Systems: Performance Dynamics and Optimization

The use of unmanned aerial vehicle (UAV)- based communication in millimeter-wave (mmWave) frequencies to provide on-demand radio access is a promising approach to improve capacity and coverage in beyond-5G (B5G) systems. There are several design aspects to be addressed when optimizing for the deployment of such UAV base stations. As traffic demand of mobile users varies across time and space, dynamic algorithms that correspondingly adjust the UAV locations are essential to maximize performance. In addition to careful tracking of spatio-temporal user/traffic activity, such optimization needs to account for realistic backhaul constraints. In this work, we first review the latest 3GPP activities behind integrated access and backhaul system design, support for UAV base stations, and mmWave radio relaying functionality. We then compare static and mobile UAV-based communication options under practical assumptions on the mmWave system layout, mobility and clusterization of users, antenna array geometry, and dynamic backhauling. We demonstrate that leveraging the UAV mobility to serve moving users may improve the overall system performance even in the presence of backhaul capacity limitations.

Fourier transform infrared–photoacoustic spectroscopy of poly (N‐butyl methacrylate) adsorbed from solution on alumina

Fourier transform infrared-photoacoustic spectroscopy (FTIR-PA) has been used to investigate the adsorption of poly(n-butyl methacrylate) (PnBMA) from solution on alumina. Qualitative and quantitative analysis of the FTIR-PA spectra of PnBMA adsorbed from cyclohexane, benzene, and carbon tetrachloride on alumina were performed. The efficiency of adsorption was found to increase in the order of C6H12 . CCl4 . C6H6. Methanol and tetrahydrofuran, on the other hand, showed negative adsorption. The effects of temperature and the amount of adsorbent were also investi- gated and it was observed that the adsorption of PnBMA has a negative temperature coefficient. © 1998 John Wiley & Sons, Inc.

Plant secondary compounds and soil microbial processes in carbon and nitrogen cycling in relation to tree species

The aim of this study was to explore soil microbial activities related to C and N cycling and the occurrence and concentrations of two important groups of plant secondary compounds, terpenes and phenolic compounds, under silver birch (Betula pendula Roth), Norway spruce (Picea abies (L.) Karst) and Scots pine (Pinus sylvestris L.) as well as to study the effects of volatile monoterpenes and tannins on soil microbial activities. The study site, located in Kivalo, northern Finland, included ca. 70-year-old adjacent stands dominated by silver birch, Norway spruce and Scots pine. Originally the soil was very probably similar in all three stands. All forest floor layers (litter (L), fermentation layer (F) and humified layer (H)) under birch and spruce showed higher rates of CO 2 production, greater net mineralisation of nitrogen and higher amounts of carbon and nitrogen in microbial biomass than did the forest floor layers under pine. Concentrations of mono-, sesqui-, diand triterpenes were higher under both conifers than under birch, while the concentration of total water-soluble phenolic compounds as well as the concentration of condensed tannins tended to be higher or at least as high under spruce as under birch or pine. In general, differences between tree species in soil microbial activities and in concentrations of secondary compounds were smaller in the H layer than in the upper layers. The rate of CO 2 production and the amount of carbon in the microbial biomass correlated highly positively with the concentration of total water-soluble phenolic compounds and positively with the concentration of condensed tannins. Exposure of soil to volatile monoterpenes and tannins extracted and fractionated from spruce and pine needles affected carbon and nitrogen transformations in soil, but the effects were dependent on the compound and its molecular structure. Monoterpenes decreased net mineralisation of nitrogen and probably had a toxic effect on part of the microbial population in soil, while another part of the microbes seemed to be able to use monoterpenes as a carbon source. With tannins, low-molecular-weight compounds (also compounds other than tannins) increased soil CO 2 production and nitrogen immobilisation by soil microbes while the highermolecular-weight condensed tannins had inhibitory effects. In conclusion, plant secondary compounds may have a great potential in regulation of C and N transformations in forest soils, but the real magnitude of their significance in soil processes is impossible to estimate.
Programme for International Student Assessment (PISA) Reading Competencies: A Study of the Factors in Academic Reading

Abstract The purpose of the present study is to identify the explanatory and predictive correlations between the awareness of meta-cognitive strategies in reading, teacher stimulation, reading attitude, and the frequency of academic reading in light of the PISA 2009 dataset. The study was based on the data in Turkey revealed by PISA, a project carried out by the OECD. The measurement models were formed by the data on a total of 3781 students after incomplete data were excluded, and an attempt was made to test the models where reading attitude served as full mediator or partial mediator. The findings suggested that the awareness of meta-cognitive strategies in reading and teacher stimulation had a positive influence on reading attitude, which, in turn, positively affected the frequency of academic reading. In addition, reading attitude served as partial mediator of the effect that teacher stimulation and the awareness of strategies had on the frequency of academic reading. It can be concluded that it will be a step in the right direction for teachers to stimulate their students during reading activities and to teach them how to use strategies. Acquired through experiences, positive reading attitude can contribute to students’ academic experiences.

In case ofT21 model integration, the maximum speedup and efficmncy acl~Lleved on 16 processors are about 10 and 63%, respectively. When the horizontal resolution of the model is doubled to T42, the maximum speedup and efficiency obtained on 32 processors are about 9 and 29%, respectively. It is also found that when the physical parametrisatmn schemes are mcluded In the model and thereby the number of arithmetic operations are increased, the speedup and efficiency of 16 as well as 32 processors increase compared to the case voth no physics m the model.
A Novel Approach for Efficient and Convenient E-Auction

This paper presents a novel approach for efficient and convenient e-auction by comparing the performance between first-price and second-price sealed bid auction. This studied entry and bidding patterns in first-price and second-price sealed bid auction and documented a set of systematic effects on these two auctions. It is found that the first-price auction gives rise to larger levels of efficiency and revenue, but lower payoffs to the bidders. The latter finding is the second-price auction is a dominant strategy for a buyer to drop out of the bidding when the asking price reaches his or her valuation. This paper first demonstrates on the implementation of first-price and second-price sealed bid auction. Then it talks about the concerns about comparison between them.

Photosynthetic Capacities and Productivity of Indoor Hydroponically Grown Brassica alboglabra Bailey under Different Light Sources

A major challenge for growing vegetables in an indoor vertical farming system will be supplying not only sufficient quantity but also quality of light. It has been reported that yield of crops is enhanced under appropriate combination of red and blue light compared with red light alone. This project aims to investigate the effects of different combinations of red and blue. Plants were cultured for a 12-h photoperiod at 210 μmol·m–2·s–1 photosynthetic photon flux density (PPFD) under different combinations of red (R) and blue (B) light-emitting diodes (LED). The R:B-LED ratios are: 1) 100:0 (0B); 2) 92:8 (8B); 3) 84:16 (16B) and; 4) 76:24 (24B). All combined RB-LEDs significantly increased light-saturated photosynthetic CO2 assimilation rate (Asat), stomatal conductance (gs sat) and productivity compared with those under 0B. Results suggested that 16B was the most suitable combination of LEDs to achieve the highest productivity for B. alboglabra. To further substantiate these results, comparative studies were conducted under equal photoperiod and PPFD among 16B (RB-LED), white LED (RBW-LED) and high-pressure sodium (HPS) lamps. Shoot, root biomass, leaf number, leaf mass per area and Asat were higher in plants under HPS lamps and RB-LED, than under RBW-LED. However, gs sat was lower under RB-LED and RBW-LED, than under HPS lamps. Plants under RB-LED had higher electron transport rate and photochemical quenching but lower non-photochemical quenching than those under RBW-LED and HPS lamps. Thus, these results more conclusively affirmed that 16B was the most suitable light source to achieve the highest photosynthetic capacities. The findings of this study could also be used in vertical farming to achieve the highest productivity of vegetable crops such as B. alboglabra within the shortest growth cycle with reduced energy consumption.
In-cloud processes of methacrolein under simulated conditions – Part 2: Formation of secondary organic aerosol

The fate of methacrolein in cloud evapo-condensation cycles was experimentally investigated. To this end, aqueous-phase reactions of methacrolein with OH radicals were performed (as described in Liu et al., 2009), and the obtained solutions were then nebulized and dried into a mixing chamber. ESI-MS and ESI-MS/MS analyses of the aque-ous phase composition denoted the formation of high molecular weight multifunctional products containing hydroxyl, carbonyl and carboxylic acid moieties. The time profiles of these products suggest that their formation can imply radical pathways. These high molecular weight organic products are certainly responsible for the formation of secondary organic aerosol (SOA) observed during the nebulization experiments. The size, number and mass concentration of these particles increased significantly with the reaction time: after 22 h of reaction, the aerosol mass concentration was about three orders of magnitude higher than the initial aerosol quantity. The evaluated SOA yield ranged from 2 to 12%. These yields were confirmed by another estimation method based on the hygroscopic and volatility properties of the obtained SOA measured and reported by Michaud et al. (2009). These results provide, for the first time to our knowledge, strong experimental evidence that cloud processes can act, through photooxidation reactions, as important contributors to secondary organic aerosol formation in the troposphere.
1 A Trajectory Based Estimate of the Tropospheric Column Ozone Column Using the Residual Method

We estimate the tropospheric column ozone using a forward trajectory model to increase the horizontal resolution of the Aura Microwave Limb Sounder (MLS) derived stratospheric column ozone (SCO). Subtracting the MLS SCO from Ozone Monitoring Instrument (OMI) column measurements gives the trajectory enhanced tropospheric ozone residual (TTOR). Because of different tropopause definitions, we validate the basic residual technique by computing the 200hPato-surface column (200TSC) and comparing it to the same product from ozonesondes and Tropospheric Emission Spectrometer measurements. Comparisons show good agreement in the tropics and reasonable agreement at middle latitudes, but there is a persistent low bias in the TTOR that may be due to a slight high bias in MLS SCO. With the improved SCO resolution, we note a strong correlation of extra-tropical TCO anomalies with probable troposphere-stratosphere exchange events or folds. The folds can be identified by their co-location with strong horizontal tropopause gradients. TTOR anomalies due to folds may be mistaken for pollution events since folds often occur in the Atlantic and Pacific pollution corridors. We also compare the 200TSC with Global Modeling Initiative (GMI) chemical model estimates of the same quantity. While the tropical comparisons are good, we note that GMI variations in 200TSC at middle latitudes are much smaller than seen in the TTOR.
Circularly Polarized Microstrip Patch Antenna Using Artificial Magneto-Dielectric Substrate with Grid Structure

We propose a circularly polarized microstrip patch antenna that use an artiflcial magneto-dielectric (AMD) substrate. The proposed antenna has a square patch with dual feeding points and uses a Wilkinson power divider in order to achieve a circularly polarized radiation pattern. The AMD substrate is constructed with a two-dimensional array of single split ring resonators. The antenna has an axial ratio of less than 1.7dB, peak gain of 0.55dBic, and exhibits a right handed circular polarized radiation pattern at Korean UHF RFID service band. The size of the antenna is 100mm £ 100mm £ 5:2mm and the radiating patch measures 65mm£65mm (0:199‚0£0:199‚0).
Biaxial Material Design Method for the ReducedAperture Waveguide Model

Brand, Jason. M.S.Egr. , Department of Electrical Engineering, Wright State University, 2014. Biaxial Material Design Method for the Reduced Aperture Waveguide Model. The design and characterization of metamaterials has emerged as a field of great interest in electromagnetics in recent years. The characterization has been accomplished primarily by means of fabrication, measurement, and parameter estimation. Previous work by Knisely and Havrilla [8] has shown that biaxial anisotropy can be created by machining air vias uniaxially into a homogeneous, isotropic material. This research project proposes a design method for manufactured biaxial materials. Full wave modeling and simulation is used for samples with varying via size, separation and pose to obtain the scattering parameters S11 and S21. To compare the simulated S-parameters to theoretical S-parameters of different dielectric values solved by mode matching, a cost function was created. The cost function is minimized using a constrained non-linear least squares optimization technique. When the global minimum of the cost function is found the material parameter for the values that optimized the function are estimated to be the values of the simulated material.
