MARKERLESS AUGMENTED REALITY PADA PERANGKAT ANDROID

Teknologi augmented reality sangat informatif dan menarik. Saat ini penelitian dan penggunaan Augmented reality meluas hingga ke berbagai aspek, contohnya dalam bidang kesehatan, militer, hiburan, fashion, komersial, hingga game. Teknologi Augmented reality tradisional diaplikasikan dengan menggunakan Marker (Penanda) pada komputer pribadi dengan bantuan web camera. Penggunaan marker yang berupa frame hitam putih dan seluruh bagiannya harus terlacak membuat penggunaan ruang pada obyek yang dilacak menjadi tidak efisien, kurang menarik dan tidak praktis. Teknologi Markerless Augmented reality yang dikembangkan dalam perangkat Android diharapkan dapat membuat implementasi augmented reality jauh lebih efisien, praktis, menarik, dan bisa digunakan dimanapun, kapanpun, oleh siapapun tanpa perlu mencetak marker. Pada penelitian ini dilakukan perancangan markerless augmented reality dengan memanfaatkan fitur sudut sebuah citra, melacak fitur tersebut, mendefinisikan koordinat citra lalu menampilkan obyek virtual pada sebuah citra target (image target), pada sebuah target kotak enam sisi bertekstur (multi target), dan mengaplikasikan tombol virtual (virtual button) dalam image target. Hasil yang didapat pada penelitian ini yaitu, jumlah fitur sudut yang harus terdapat pada sebuah image target harus berjumlah minimal 9 fitur dengan pola yang acak. Jumlah image target pembentuk minimal yang harus terdeteksi pada multi target agar dapat dilacak oleh sistem adalah 1 dari 6 image target pembentuk. Dan pada virtual button, ukuran minimal virtual button adalah 16x16 piksel atau 0,138% dari citra berukuran 497x373piksel agar dapat terlacak oleh sistem.
Distinguishing topologically and smoothly doubly slice knots

We construct an infinite family of smoothly slice knots that we prove are topologically doubly slice. Using the correction terms coming from Heegaard Floer homology, we show that none of these knots is smoothly doubly slice. We use these knots to show that the subgroup of the double concordance group consisting of smoothly slice, topologically doubly slice knots is infinitely generated. As a corollary, we produce an infinite collection of rational homology 3‐spheres that embed in S4 topologically, but not smoothly.
Sound propagation in areas with a complex meteorology: a meteorological-acoustical model

Long range sound propagation is largely affected by the vertical wind and temperature gradients. In areas where the meteorology can be complex, such as coastal areas, islands, and lake districts, the gradients usually vary as a function of the horizontal distance. As a result the sound propagation in these areas cannot be calculated with "standard" acoustic models, such as the ISO 9613 or Harmonoise engineering model. By using a combination of an advanced meso-scale meteorological model and an acoustical model, that incorporates horizontal and vertical meteorological variations, long range sound propagation in such complex areas is calculated. In this paper we present two applications of this hybrid meteorological-acoustical calculation scheme: i) propagation of impulse noise in a coastal area, and ii) propagation of industrial noise in a rural area with a lake. For the coastal area sound level contours have been calculated as a function of the meteorology for an entire year. For the lake area the effect of the lake on the sound propagation is demonstrated.
A Bilingual Numeral OCR System for Creating Uni-Lingual Digitized Numeral Document

The optical character recognition has been used in many applications such as dictionary generation, customer billing system, banking and postal automation, and library automation etc. The bilingual OCR system to make uni-lingual script helps us to reduce the requirement of two different OCR systems into a single OCR system for recognition of two different languages. This type of globalization helps the universal users of any language can read the text documents in their self-language if the bilingual documents are converted into uni-lingual document. In this paper, the image which contains printed Tamil and European numerals has been recognized using common OCR System and the Tamil numerals are converted into European numerals to globalize the document from a bilingual script into a uni-lingual document. The main objective of the work is to bring out the single numeral (European numerals) text document from the input image with two different numerals (Tamil and European Numerals). The Kohonen’s self-organizing map (SOM) based recognition system has been used for recognizing the numerals and recognized characters in bilingual numerals (Tamil and European Numerals) form are converted into Uni-lingual form (European numerals). This paper also discusses the various approaches used for OCR.
Searching for Common Ground on Hamas Through Logical Argument Mapping

Robert Fogelin (1985) formulated the thesis “that deep disagreements cannot be resolved through the use of argument, for they undercut the conditions essential to arguing. ” The possibility of arguing presupposes “a shared background of beliefs and preferences,” and if such a background is not given, there is no way of “rational” dispute resolution. By contrast to this pessimistic view, I will propose a method that has been developed to overcome difficulties as described by Fogelin.
TRIGGERING OF 178m2 HF ISOMER EMBEDDED IN Ta MATRIX BY 30 keV ELECTRONS

178m2 Hf isomer triggering was studied using the upgraded experimental setup developed in Kharkiv National University and installed at Kyiv Institute for Nuclear Research. The target presenting a single Ta foil of 300 „m thickness with 178m2 Hf isomeric activity of about 100 Bq was irradiated by 30 keV electron beam. The enhanced counting rates of all the ground-state band transitions were observed. Our data are consistent with an estimate for the triggering efiect of (2:9 § 0:7)% and corresponding triggering cross-section can qualitatively be estimated as aetrig = 4:2 £ 10 i27 cm 2 .
Intermodal Contour Accessibility Measures Computation Using the 'UrMo Accessibility Computer'

Contour accessibility measures form a set of performance indicators used to value a location by the amount of accessible activities, places, or space within certain time or distance limits. They are used for evaluating a region's activity potential taking the connectivity to its surroundings into regard and act as input data for land use planning models and traffic demand models. With the availability of disaggregated data and sufficient computer power, accessibility measures can be computed at a very fine-grained level of single buildings, points of interest or areas. This approach considers single routes through the transportation network and allows for computing intermodal accessibilities which assume a usage of multiple carriers along a single way. This report presents a tool that realizes such a disaggregated computation of accessibility measures. A strong focus is put on the tool's internal computation steps for supporting a reference to potential users.
Preparation of natural methane samples for stable isotope and radiocarbon analysis

We describe procedures for preparing methane samples from natural waters or sediments for radiocarbon (14C‐CH4) analysis. These procedures also allow the determination of 2H/1H and 13C/12C ratios of this methane. Methane is extracted from natural samples in the field using Lamont radon stripping boards (Mathieu et al. 1988) and trapped using liquid nitrogen‐cooled U‐traps filled with HiSiv 3000. The field procedures eliminate the need to return large samples to the laboratory. The U‐traps are returned to the laboratory where a new twostage purification‐oxidation vacuum line is used to extract, purify, and oxidize the methane. The methane oxidation products (carbon dioxide and water) are analyzed for the natural content of 14C, 2H, and 13C with standard procedures. These procedures were evaluated under the conditions that methane was extracted from between 19 to 114 L water or 0.07 to 0.35 L sediment. No isotope fractionation was observed and the blanks are small (0.528 ± 0.39 µmol methane with radiocarbon content 14C/C = 96.1 ± 0.3 pMC [percent Modern Carbon] [Stuiver and Polach 1977]). Using 14C‐accelerator mass spectrometry (AMS), these procedures can produce a successful radiocarbon measurement when at least 1.81 µmol methane are collected. Thus, 14C‐CH4 measurements can be made when the dissolved methane concentration is between saturation (mM) and 15.9 nM for the water column or 5.2 µM for the sediment.
Distribution and diversity of mosquitoes and the role of Aedes in the transmission of arboviruses in selected districts of Tanzania

Arboviruses belong to various families of viruses that are transmitted by arthropods, mainly mosquitoes and often cause diseases in humans. The objective of this study was to determine mosquito diversity and transmission of arboviruses by Aedes in selected ecosystems in Tanzania. Adult mosquitoes were collected from rural and urban settings using carbon dioxide-baited CDC light traps, Biogent sentinel traps, and the Mosquito Magnet traps. Reverse Transcription-Polymerase Chain Reaction assay was performed on pooled adult Aedes mosquitoes to detect the presence of Chikungunya, Dengue, Rift Valley fever (RVF) and Yellow fever (YF) viruses. A total of 42, 77 mosquitoes belonging to five genera (Aedes, Anopheles, Culex, Mansonia and Mimomyia) and 18 species were collected. Culex accounted for the largest (62.7%; n= 2,682) proportion of the mosquitoes while Anopheles for the lowest proportion (5.7%; n=245). Of the total mosquitoes collected, Culex quinquefasciatus accounted for more than a half (53.4%; n=2692), followed by Aedes aegypti 12.1% (n=520). Of the 34 adult Ae. aegypti pools tested, arboviruses were detected in 33(97%) pools. Dengue virus was detected in 47.6% (10/ 21) pools which tested positive for Flaviruses. Chikungunya virus was detected in 30% (3/ 10) pools which were positive for Alphavirus genera. Of 2 pools tested positive for Bunyavirus genus, Rift Valley fever virus was detected in 1 pool (50%). The presence of various mosquito vectors and detection of arboviruses in aedes mosquitoes leave the population of Tanzania at great risk of transmission of different pathogens and highlight a need for vector control measures in the country.
Innovation Complementarity and Environmental Productivity Effects: Reality or Delusion? Evidence from the EU

Innovation is a key element behind the achievement of desired environmental and economic performances. Regarding CO2, mitigation strategies would require cuts in emissions of around 80-90% with respect to 1990. We investigate whether complementarity, namely integration, between the adoption of environmental innovation measures and other technological and organizational innovations is a factor that has supported reduction in CO2 emissions per value added, that is environmental productivity. We merge new EU CIS and WIOD meso level data to assess the innovation effects on sector CO2 performances at a wide EU level. We find that jointly adopting different innovations is not a significant factor to increase environmental productivity, neither for the entire economy nor for manufacturing or narrower ETS sectors. The only case where a complementarity arises is for Northern EU manufacturing sectors that integrate eco innovations with product and process innovations to support environmental productivity. We believe that the lack of integrated innovation adoption behind environmental productivity performance is a signal of the current weaknesses economies face in tackling climate change and green economy challenges. Incremental rather than more radical strategies have predominated so far; this is probably insufficient when we look at long-term economic and environmental goals.
A Uniqueness Theorem for Initial-Boundary Value Problems in Tellegen Medium

Uniqueness of the initial-boundary value problems for a Tellegen media is studied. Initial-boundary value problems for a Tellegen Medium are summarized for the sake completeness; the conservation of energy for such a medium is reviewed. Sufficient conditions are given for the positive definiteness of the energy stored in a Tellegen media due to the fields. It is shown that the if the energy stored in a Tellegen medium is positive definite, then an initial- boundary value problem for a Tellegen media has only one solution, if it exists.

Simultaneous determination of nitrous oxide and ammonia for measurement of in-situ fluxes from natural ecosystems by gas chromatography with headspace autosampler and electron capture detection

Anthropogenic disturbance of the soil nitrogen cycle by changes in nitrogen and carbon availability influences the production of N2O and NH 3 emissions to the atmosphere affecting the environment and human health. This dissertation presents a new method for automated gas chromatographic analysis of N2O and NH3 and quantifies fluxes from a salt marsh and tropical rain forest. The automated system used single column gas chromatograhic separation on HayeSep Q and electron capture detection. Air (N2+O 2), N2O and NH3 are separated with retention times of 0.9, 1.7 and 2.15 minutes respectively. Samples were stored in headspace autosampler vials until analysis. The precision was 3--7% RSD for standards of N2O with a LOD of 0.001 ppmv and 3--12% RSD for standards of NH3 with a LOD of 0.002 ppmv. Nitrogen dynamics of an oil contaminated salt marsh (Spartina alterniflora) were examined to assess the effects of three bioremediation strategies: air purging, nitrate addition and full fertilizer addition. Compared to values reported in uncontaminated marshes N2O fluxes were lower by a factor of 7, and NH3 fluxes were slightly higher. This suggests that the petroleum had an inhibitory affect on denitrification but not mineralization. Extractable NO3levels were 2--5 fold lower than those reported in the literature and NH4+ levels were 3 to 80 fold higher. The higher NH4+ levels suggest that oil contamination might inhibit nitrification and as a result could explain the reduced levels of NO3and N2O flux. Hurricanes in the Caribbean can cause short term disturbances in trace gas flux, litter fall and plant structure in forests. The hurricane appears to have increased the N2O flux four fold, and caused a 40% increase in NO3soil concentration while the NH4+ soil concentration is lower by two fold than previous levels (1995--97). N2O flux and NO3concentrations returned to previous levels after 27 months, but not NH4+ concentrations. A correlation between NH3 and N2O flux suggests that the increased "litter pulse" from deforestation results in increased N availability in the soil and thus an increase in N 2O flux.
Biomass production and feed quality of three summer fodder species planted under two nitrogen levels

Three fodder species namely millets, sorghum and sudan grass were grown at Agronomy Research Farm of NWFP Agricultural University, Peshawar during summer 2002. Objective of this study was to compare growth, b iomass production and chemical composition of the fodder species under low (90 kg ha -1 ) and high (135 kg ha -1 ) nitrogen (N) supplies for inter and intra species comparison. Field was prepared wi th normal cultural practices and planting was done in rows 30 cm apart in a randomized complete block design (RCBD). Each treatment was replicated four times with maximum 8 rows per experimental unit. Each experimental unit was of 5. 0 m length and 2.4 m width. Fertilizer was uniforml y broadcasted amounting 90 (N), 60 (P) and 40 (K) kg ha -1 at the time of seedbed preparation. High N treatme nt was subsequently applied as 45 kg N ha -1 , 25 days after sowing. Planting was done on July 1 1, 2004. Periodic growth was additionally observed from germination to 50% flowering for about 65 day duration. Fresh matter (FM) dry matter (DM) relative wat er content (RWC), plant height (PH), leaf number plant -1 (LN), leaf to stem ratio (LSR) and crop growth (CG R) were recorded. Samples were analyzed for ash content, crude protein (CP), in vi tro dry matter digestibility (IVDMD). Metabolized e nergy (ME) was estimated from the IVDMD results. N levels signific antly affected (P<0.05) FM and DM of millet but did not influence yield of sorghum and sudan grass. Millet was highest (P<0 .05) in production than any other species. However, sorghum and sudan grass did not differ from each other. RWC of all th e three species did not show any statistical differ ence. PH of millet was maximum (P<0.05) than sorghum and sudan grass. LN mimicked sequence already explained for PH. LSR decreased for millet with increasing N supply. CGR during the lin ear growth phase decreased significantly for millet s under low N. Among the fodder quality parameters, all observatio n found non-significant for the species irrespectiv e of the N levels. However, millets showed higher (P<0.05) ash content, CP, IVDMD and ME to sorghum and sudan grass. The study suggests that among the fodder species, millet yielded great er biomass in an area where the natural precipitati on is enough to meet the crop water demand. Additionally high N application improved both forage quantity and quality.
Spin-glass model with essential short-range competing interactions

We consider a proton-glass model with an arbitrary range of competing interactions within two-particle cluster approximation for the free energy and within symmetric replica approach. We show that for the thermodynamic characteristics, the Gaussian approximation for distribution functions of cluster fields can be used. For a simpler proton-glass model with weak long-range interactions (linear approximation) we study the effect of the long-range interactions and random internal fields on the phase diagram and thermodynamics characteristics. It is shown that small fluctuations of internal fields can lead to essential smearing of proton-glass transition region. The adaptability of the theory for a description of proton-glasses of Rb1−x(NH4)xH2PO4-type is discussed.
Molecular Characterization and Identification of Burkholderia Multivorans BPSS Isolated from Fecal Contents of Pteropus Giganteus in Udaipur, Rajasthan, India

Previous and ongoing studies have incriminated bats as reservoirs of several emerging and re-emerging zoonoses. Most of these studies, however, have focused on viral agents and neglected important bacterial pathogens. To date, there has been no report investigating the prevalence of Burkholderia multivorans spp. in bats. The Burkholderia genus, being the largest, consists of Gram-negative, forms part of the Burkholderia complex, a group of Gram negative organisms which are commonly found in soil and water. And can survive for prolonged periods in moist environments. These bacteria can act as a powerful pesticide, capable of eliminating many soil-borne plant pathogens. Many species of Burkholderia are of considerable economic importance as these serve as insecticides, cause food poisoning, produce antibiotics etc. Hence in the present study an effort has been made to elucidate the presence of Burkholderia multivorans BPSS isolated, characterized and identified from the faeces of Pteropus giganteus from Udaipur, Rajasthan India. Its phylogenetic tree has also been derived, which showed evolutionary relationship of eleven related taxa. This is the first report from Indian subcontinent correlating the role of this megachiropteran as a carrier of Burkholderia multivorans BPSS.
Taking evolutionary circuit design from experimentation to implementation: some useful techniques and a silicon demonstration

Current techniques in evolutionary synthesis of analogue and digital circuits designed at transistor level have focused on achieving the desired functional response, without paying sufficient attention to issues needed for a practical implementation of the resulting solution. No silicon fabrication of circuits with topologies designed by evolution has been done before, leaving open questions on the feasibility of the evolutionary circuit design approach, as well as on how high-performance, robust, or portable such designs could be when implemented in hardware. It is argued that moving from evolutionary 'design-for experimentation' to 'design-for-implementation' requires, beyond inclusion in the fitness function of measures indicative of circuit evaluation factors such as power consumption and robustness to temperature variations, the addition of certain evaluation techniques that are not common in conventional design. Several such techniques that were found to be useful in evolving designs for implementation are presented; some are general, and some are particular to the problem domain of transistor-level logic design, used here as a target application. The example used here is a multifunction NAND/NOR logic gate circuit, for which evolution obtained a creative circuit topology more compact than what has been achieved by multiplexing a NAND and a NOR gate. The circuit was fabricated in a 0.5 mum CMOS technology and silicon tests showed good correspondence with the simulations.
Organic C levels in intensively managed arable soils – long‐term regional trends and characterization of fractions

Substantial losses of soil organic carbon (SOC) from the plough layer of intensively managed arable soils in western Europe have recently been reported, but these estimates are associated with very large uncertainties. Following soil surveys in 1952 and 1990 of arable soils in West Flanders (Belgium), we resampled 116 sites in 2003 and thus obtained three paired measurements of the OC stocks in these soils. Ten soils were selected for detailed physical fractionation to obtain possible further explanations for changes in SOC stocks. Between 1990 and 2003, the SOC stocks decreased at an average rate of −0.19 t OC ha−1 year−1. This loss is significant but is still less than half the rate of SOC decrease that was estimated previously for the whole region of Flanders, which includes the study area. Variation in SOC stocks or in the magnitude of SOC stock losses could not be related to soil texture, to changes in ploughing depth, or to recent land‐use changes. A good relationship, however, was found between the SOC losses and organic matter (OM) inputs. The results of the physical fractionation also suggested management to be the predominant factor determining variation in SOC stocks because no correlation was found between soil texture and the absolute amounts of OC present in the largest OM fractions, that is, the OC in free particulate organic matter (POM), and OC associated with the silt + clay size fraction. The proportion of OC in free POM was up to 40% of the total OC, which indicates the important impact of management on SOC and also indicates that a substantial part of the SOC still present, may in the future be lost at a time scale of years to decades assuming that the intensive management continues.
