A Swarm Based Approach to Improve Traditional Document Clustering Approach

Clustering, an extremely important technique in Data Mining is an automatic learning technique aimed at grouping a set of objects into subsets or clusters. The goal is to create clusters that are coherent internally, but substantially different from each other. Text Document Clustering refers to the clustering of related text documents into groups based upon their content. Document clustering is a fundamental operation used in unsupervised document organization, text data mining, automatic topic extraction, and information retrieval. Fast and high-quality document clustering algorithms play an important role in effectively navigating, summarizing, and organizing information. The documents to be clustered can be web news articles, abstracts of research papers etc. The aim of this paper is to provide efficient document clustering technique involving the application of soft computing approach and the use of swarm intelligence based algorithm.
SMITH DIAGRAM FOR LOW REYNOLDS NUMBER AXIAL

Compressor operation at low Reynolds numbers is commonly associated with a loss increase. A semi-analytical approach was used to investigate this region of the design spectrum. To do this, an axial rotor with constant diameter endwalls was non-dimensionalised to understand the influence of different design parameters independently. Smith diagrams showing contours of efficiency on a plot of flow coefficient versus stage loading coefficient were produced at low and high Reynolds numbers. The results showed not only lower levels of efficiency at low Reynolds numbers but a much narrower high efficiency island, with losses rapidly increasing as the design moved away from the high efficiency region. Several points in the Smith diagram were selected, dimensionalised and simulated using CFD with and without a transition model. Good agreement between the CFD and the model was found, with discrepancies increasing towards low efficiency regions. Meanline correlations for the low Reynolds number regime were also provided.
Permission based malware detection in android devices

The mobile operation system Android is one of the most OS's used in the entire world, which make it the target of many malware projects and the mission of detecting those malware applications is getting harder over time due to evaluation and development of techniques that make possible for those malwares to hide their maliciousness activities from anti-malware techniques by obfuscating the code source of application or even hiding malicious activities when it's getting to scan by an anti-malware, for this purpose many researchers have paid attention to this subject by proposing different approaches using newest technologies of machine learning and reverse engineering to deal with this problematic. In this paper a permission-based approach is proposed for detecting malwares in android applications using filter feature selection algorithms to select features and machine learning algorithms Random Forest, SVM, J48 for classification of applications into malware or benign.
Rethinking the Problem of Linguistic Categorization for Global Search Engines

The fields of social psychology and neuroscience have known for several decades that culture affects the way people carve up the world. This perceptual difference is often, but not always, aligned with similar differences in linguistics categories. If correct, this problem of linguistic categorization may have considerable impact on search algorithms. This paper examines the relationship between culture and linguistic categorization for global search engines. A total of 43 American and Chinese participants completed two classification tests, one derived from social psychology and neuroscience and the other based on a common classification problem for full-text searching. These data suggest that Chinese participants are more field dependent, American participants are less field dependent, and that these results may offer important clues about adapting search algorithms for global computing systems.
Title Product Construction of Affine Codes

Binary matrix codes with restricted row and column weights are a desirable method of coded modulation for power line communication. In this work, we construct such matrix codes that are obtained as products of affine codes—cosets of binary linear codes. Additionally, the constructions have the property that they are systematic. Subsequently, we generalize our construction to irregular product of affine codes, where the component codes are affine codes of different rates.
Cramer-Rao bounds for passive range and depth in a vertically inhomogeneous medium

Cramer-Rao bounds are established for passive location in a multipath environment with an array of multiple sensors. The source signature is wideband stationary and the background noise is white. General expressions are derived for the bounds, and the performance gain contributed by the interpath delays over location techniques based on wavefront curvature only (i.e. spatial processing across the array of sensors) is shown. <<ETX>>

A prospective study of BISAP score in assessing severity of acute pancreatitis

Acute pancreatitis is defined as an inflammatory process of the pancreas with possible peri pancreatic tissue and multi-organ involvement inducing Multi-Organ Dysfunction Syndrome (MODS) with an increased mortality rate.The underlying mechanism of injury in pancreatitis is thought to be premature activation of pancreatic enzymes within the pancreas, leading to a process of auto digestion. Once the cellular injury has been initiated, the inflammatory process can lead to pancreatic edema, hemorrhage and, eventually necrosis. As inflammatory mediators are released into circulation, systemic complications can arise, such as Hemodynamic instability, Bacteraemia (due to translocation of gut flora), Acute Respiratory Distress Syndrome and pleural effusions, gastrointestinal haemorrhage, renal failure and Disseminated Intravascular Coagulation (DIC).
COMPARISON OF NUMERICAL METHODS (BI-CGSTAB, OS, MG) FOR THE 2D BLACK-SCHOLES EQUATION

In this paper, we present a detailed comparison of the performance of the numerical solvers such as the biconjugate gradient stabilized, operator splitting, and multigrid methods for solving the two-dimensional Black–Scholes equation. The equation is discretized by the finite difference method. The computational results demonstrate that the operator splitting method is fastest among these solvers with the same level of accuracy.
Resource Return on Investment under Markup Pricing

In the (very) long run, a sustainable economy must rely on renewable resources. Until that time, an economy can be based on either renewable resources alone or a mix of renewable and non-renewable resources, but the particular mix may constrain the types of economic structures that are possible. A particularly important consideration is the quantity of resources required to extract the resources on which the economy is based, whether it is seeds retained for planting or petroleum used to extract oil. In the case of energy this is called “energy return on energy investment”, or EROI. More generally, it can be considered “resource return on resource investment”, or RROI. EROI has drawn attention lately both because the EROI of fossil fuels is falling and because the EROI of some renewable alternatives – especially for liquid fuels – is low compared to fossil fuels. In conventional economic analysis it is not clear what the relation between EROI, energy price, and macroeconomic outcomes might be. However, it raises immediate concerns within an Ecological Economic framework, in which resources – which may contribute only a small amount to GDP – are viewed as essential to the functioning of the economy. Resources are pictured as sitting at the base of an inverted pyramid, with the rest of the economy balanced on top of them. In this paper we show that when prices are set by markup, a standard Post-Keynesian assumption, then the “inverted pyramid” picture of the economy emerges naturally. We use this result to develop a computational framework for a “markup economy”, and apply it to the question of the macroeconomic impact of changes in resource prices and resource return on investment. We use the resulting model to explore several macroeconomic questions, demonstrating that the model is quite useful for exploring the role of natural resources in the macroeconomy. We then show our main result, that RROI has a surprisingly limited effect on real wages until it reaches quite low values.
Medicinal and pharmacological properties of Andrographis paniculata

A lot of literature reviews about Andrographis paniculata has been published previously. Researchers are critically involved in the research to extract out the potential medicinal value that possess by the “King of Bitter”. It has a broad pharmacological value. Traditionally many disease condition have been treated successfully. The success of the plant is due to the presence of few bioactive compounds such as andrographolide, homo-andrographolide andrographesterol, andrographopne which are identified through the phythochemistry studies of the plant which are having the wide therapeutic activities. The extremely bitter taste of the plant is due the compound known as andrographolide. However this bitter plant is having a sweet future for those appreciated the benefits of the plant. From the review it is proven that Andrographis paniculata is having antioxidant, hepatoprotective, antimicrobial, anticancer, antivenom, anti HIV, antimalarial, antipyretic, antifertility, antidiarrhoeal, antidiabetic, antihiperlipidemic activities. Variety of literature concerning about the toxicity studies has confirmed that the plant is safe to consume although few findings revealed that consuming Andrographis paniculata for a long period of time may possess some unwanted action especially in the fertility studies.
Comparison of Delays between Twilight Time and Day Time

Traffic delay is an important measure of quality of a journey. The longer delay has the lower quality of a journey. Delay at a priority junction is expected not only to be influenced by traffic volumes on the major road but also by the surrounds environments. This article was carried out to appraise the delay at the priority junctions during twilight time and day time. Therefore, theoretical delay during these two parts of a day was determined. Then, delay base on Highway Capacity Manual 2000 (HCM2000) was compared with observe delays. The results of the analysis indicate that delay during twilight time is less than other times in a day. Similarly, the comparison between the observed delay and the HCM method show that both values are similar. Keywords—Observe delay, priority junction, twilight time, theoretical delay.
An Improved Single-Phase Transformer less Inverter for Grid-Connected PV System with Fuzzy Controller

This paper presents a high-reliability single-phase transformerless grid-connected electrical converter that utilizes super junction MOSFETs to attain high potency for electrical phenomenon applications. The planned device utilizes 2 split ac-coupled inductors that operate on an individual basis for positive and negative 0.5 grid cycles. This eliminates the shoot-through issue that's encountered by ancient voltage supply inverters, resulting in increased system dependability. Dead time isn't needed at each the high-frequency pulsewidth modulation change commutation and also the grid zero crossing instants, up the standard of the output ac-current and increasing the device potency. The split structure of the planned electrical converter doesn't lead itself to the reverse-recovery problems for the most power switches and per se super junction MOSFETs is utilised with none dependability or potency penalties. Since MOSFETs area unit utilised within the planned device high potency is achieved even at lightweight load operations achieving a high CA energy commission (CEC) or Europe potency of the device system. Index Terms—California energy commission (CEC) efficiency; European union (EU) efficiency; MOSFET inverters; high efficiency; high reliability; transformer less grid-connected photo voltaic inverter

espanolRESUMEN El almacenamiento seminal in vitro ha contribuido a la reproduccion de aves silvestres en cautiverio. Sin embargo es necesario predecir su capacidad fertilizante. Los indicadores de reaccion acrosomal (RA) espermatica se han relacionado con su capacidad fertilizante. Por lo anterior, el objetivo de este trabajo fue evaluar la capacidad de reaccion acrosomal in vitro en espermatozoides de halcon Harris, conservados en fresco y criopreservados. Se obtuvieron 64 eyaculados, los cuales fueron evaluados en fresco y posdescongelacion, 32 se diluyeron con medio Beltsville Poultry Semen Extender (BPSE) y 32 utilizando medio Lake. Se evaluaron 64 eyaculados en fresco y posdescongelacion; para la evaluacion espermatica basica se utilizo la tincion de eosina-nigrosina, y capacidad de RA fue mediante su induccion con membrana perivitelina (MPV). La movilidad espermatica en semen fresco fue mayor (P0,05). El porcentaje de espermatozoides con RA en el medio Lake, incubados con MPV posdescongelacion (45,4±2,7), fue menor (P EnglishABSTRACT Seminal storage, both fresh and cryopreserved, has contributed to the reproduction of wild birds in captivity, however, a method of predicting the fertilization capacity is needed. Indicators of the sperm acrosome reaction (AR) have been associated with its fertilization capacity. Therefore, the aim of this study was to evaluate the in vitro AR of fresh and cryopreserved Harris hawk sperm using Beltsville Poultry Semen Extender (BPSE) and Lake as diluents. 64 ejaculates were obtained and examined fresh and after thawing. The sperm basic evaluation for each ejaculate was made using eosin-nigrosin, while the ability of AR was assessed by coincubation with perivitelline layer (PVL). Sperm motility of fresh semen was higher (P0.05) after thawing. The percentage of sperm that underwent an AR when incubated with PVL post thawing in Lake (45.4±2.7) was lower (P0.05) with BPSE. It is concluded that Lake diluent was more efficient for fresh seminal storage, while BPSE diluent was more efficient for seminal cryopreservation in Harris hawk.
Rockfall hazard and risk assessments along roads at a regional scale: example in Swiss Alps

Abstract. Unlike fragmental rockfall runout assessments, there are only few robust methods to quantify rock-mass-failure susceptibilities at regional scale. A detailed slope angle analysis of recent Digital Elevation Models (DEM) can be used to detect potential rockfall source areas, thanks to the Slope Angle Distribution procedure. However, this method does not provide any information on block-release frequencies inside identified areas. The present paper adds to the Slope Angle Distribution of cliffs unit its normalized cumulative distribution function. This improvement is assimilated to a quantitative weighting of slope angles, introducing rock-mass-failure susceptibilities inside rockfall source areas previously detected. Then rockfall runout assessment is performed using the GIS- and process-based software Flow-R, providing relative frequencies for runout. Thus, taking into consideration both susceptibility results, this approach can be used to establish, after calibration, hazard and risk maps at regional scale. As an example, a risk analysis of vehicle traffic exposed to rockfalls is performed along the main roads of the Swiss alpine valley of Bagnes.
COMPARATIVE STUDY OF TWO PROTOCOLS OF ECCENTRIC EXERCISE ON KNEE PAIN AND FUNCTION IN ATHLETES WITH PATELLAR TENDINOPATHY : RANDOMIZED CONTROLLED STUDY

Mailing address: Rua Santa Clara, 215 12900-470 – Centro Bragança Paulista, SP, Brasil E-mail: ronaldoalvesdacunha@ yahoo.com. br ABSTRACT Introduction: The eccentric squat on a slope has been proved effective in conservative treatment of patellar tendinopathy, especially in the athletic population. However, several aspects such as intensity and pain during therapy still differ among authors. Objectives: To compare the effectiveness of two protocols of eccentric exercise (performed with and without pain), in the improvement of knee function and pain intensity in athletes with patellar tendinopathy. Methods: 7 athletes of both genders with diagnosis of patellar tendinopathy were selected and randomly assigned to two treatment groups. The first group of volunteers performed eccentric squat exercises on a slope with pain in the patellar tendon. The second group of volunteers was instructed to perform the same exercise, but without presenting pain in the patellar tendon during performance. The treatment lasted 12 weeks and the evaluation of pain and function was performed by the VISA-P and VAS before starting treatment, at eight weeks of intervention, and at treatment completion. Results: There was improvement in both groups when results of evaluations carried out after eight and 12 weeks of beginning of the treatment were compared with the initial evaluation; however, no significant difference between the group that performed exercise with pain and the group that performed exercises without pain was found. Analysis of the probability of obtaining clinical improvement for VISA and VAS scores at eight and 12 weeks, there was no difference between the two groups. Conclusion: A program of eccentric exercise on an inclined plane using squat, performed with or without the presence of pain, was effective in improving pain and function in athletes with patellar tendinopathy.
Obtaining of sol-gel ketorolac-silica nanoparticles: characterization and drug release kinetics

Nonsteroidal anti-inflammatory drugs (NSAIDs) are among most commonly prescribed medications worldwide. NSAIDs play an important role due to their pronounced analgesic potency, anti-inflammatory effects, and lesser side effects compared to opioids. However, adverse effects including gastrointestinal and cardiovascular effects seriously complicate their prolonged use. In the presentworkwe prepare SiO2-based nanoparticleswith ketorolac, for controlled release proposes. The nanomaterialswere prepared by the sol-gel technology at acidic conditions and two different water/alcoxide ratios were used. FTIR spectroscopy was performed in order to characterize the solids and drug-SiO2 interactions. Thermal analysis and nitrogen adsorption isotherms showed thermal stability of the drug and confirmed the presence of particles with high surface area. Transmission electron micrographies of the samples showed the nanosize particles (20 nm) forming aggregates. Drug release profiles were collected by means of UV-Vis spectroscopy and kinetic analysis was developed. Release data were fitted and 1 : 8 sample showed a sustained release over ten hours; 90% of the drug was delivered at the end of the time.

Assessing genetic diversity and population structure of Salix viminalis across Ergun and West Liao basin

Salix viminalis L. is an important shrub that has potential for use as a bioenergy crop, for phytoremediation of heavy metal contaminated soil and sewage sludge treatment. It is mainly distributed in the northeast of China, but the species has not yet been used a resource here. We examined the genetic diversity and population structure of populations from the Ergun basin and West Liao basin using 20 microsatellite markers. A high level of genetic diversity (Na = 16.45, He = 0.742) was detected for S. viminalis, and populations from the Ergun basin exhibited higher genetic diversity and private alleles numbers than the West Liao basin. The 12 populations could be divided into two clusters by both Bayesian analysis and UPGMA clustering which were consistent with the populations derived from the two basins. Moderate population differentiation (FST = 0.076) was shown in S. viminalis, and AMOVA analysis confirmed that most of the genetic variation (86.13%) was attributed to individual differences within populations, while 11.49% was attributed to differences between basins and 2.38% to differences within each basin. Significant correlations of FST/(1–FST) with log (geographic distance) among 12 populations (r = 0.634, p < 0.00) and 10 populations within the Ergun basin (r = 0.482, p = 0.0002) indicated that geographical distance was the principal factor influencing genetic structure. As most of genetic variation exist within populations, so protection measures should be focused on populations with higher genetic diversity and unique alleles, such as Tuli, Mordaga downstream, Zhadun1 and Genhe.
