Share market forecasting with LSTM neural network and sentimental trend prediction

Forecasting and predicting future trend is getting signiﬁcant importance in stock market exponently as it is volatile in nature. Stock market is an extremely complicated , unstable and volatile place due to the fact that prediction is very diﬃcult. Because of uncertainty and having scope of gaining ﬁnancial proﬁts, share market estimating and prediction has been a renowned matter in ﬁnancial and academic studies. Advanced algorithms of machine learning is required as there is no persistently appropriate prediction tool. Many research works from various sector have been done to overcome this diﬃculties of predicting stock market. In machine learning sector a lot of research work already accomplished to predict share market. Many algorithms of Machine Learning have been utilized for this kind of prediction and the result was also satisfactory. In this thesis, we will extract all the real data from Dhaka Stock Exchange (DSE) using web scrapping and try to predict stock market price on a giving day, by approaching Long Short Term Memory(LSTM) Networks based on historical data mining method. The results of this paper show that Long Short Term Memory Networks can be applied for evaluation of historical stock pricing data and acquire valuable information by forecasting future trend with suitable ﬁnancial indicators. Beside this, we will extract all the news opinions from the respective web pages (DSE, Lonkabangla ﬁnancial port) and went through noise reduction, implementing algorithm and classiﬁer to determine the sentiment polarity to come to a choice whether the stock price of a company are getting upward or downward trend. We are using na¨ıve bayes classiﬁer to examine the ratio of a sentence or phrase which can contain sentiment in from of positive, negative and neutral words. Using this model we can represent a status of some stock news.
Particle Emissions from a Small Two-Stroke Engine: Effects of Fuel, Lubricating Oil, and Exhaust Aftertreatment on Particle Characteristics

The effects of fuel and lubricating oil formulation and exhaust catalytic aftertreatment on physical and chemical characteristics of two-stroke engine exhaust particles were studied. The exhaust particles were produced with a professional chainsaw engine. The employed fuels were a 98-octane oxygenated, low-sulfur, low-aromatic reformulated gasoline, which served as a reference, and a 95-octane nonoxygenated alkylate gasoline that had no aromatics and olefins. The applied lubricating oils were a semisynthetic mineral-based oil and a biodegradable ester-based oil. In total eight fuel–lubricating oil–catalyst combinations were studied. The test runs were conducted on a test bench and exhaust was diluted in a full-flow dilution tunnel. The size and number emissions of the exhaust particles were measured with a scanning mobility particle sizer (SMPS). The organic carbon (OC) and elemental carbon (EC) composition of the particles were analyzed with a thermal–optical transmission analyzer (TOT). In addition, the inorganic ion and metal composition of the particles were quantified, and the gaseous total hydrocarbon (THC), carbon monoxide (CO), and nitrogen oxide (NOx) emissions were measured. The volatility characteristics of the exhaust particles were studied with a thermal desorption unit combined with the SMPS. The particle mass (PM) emissions ranged without catalyst from 2.9 to 3.4 g/kWh and with catalyst from 1.7 to 2.4 g/kWh, the catalytic converter thus reducing PM emissions by 19–50%. Without catalyst the alkylate fuel–biodegradable oil combination gave the highest particle mass emissions, but with catalyst with the same fuel–oil mixture the emissions were the lowest. The count median diameter (CMD) of the particles ranged from 57 to 123 nm. Without catalyst, the alkylate fuel–biodegradable oil combination gave the lowest number emissions, but with catalyst with the same fuel–oil combination the emissions were the highest. The catalytic converter reduced the particle size by 22–56 nm, but it also increased the number emissions by a factor of 1.3–2.6. In thermal analysis 88–98% of the exhaust particle volume proved to be volatile, the solid fraction consisting of elemental carbon and metal residues. With the mineral-based lubricating oil, the metal residues appeared in two modes at the evaporation temperatures of 350°C and higher, while in the particles produced with the biodegradable oil the residues were unimodally distributed.
Electric-field-induced conductance transition in 8-hydroxyquinoline aluminum (Alq3)

We report an electric-field-induced conductance transition from an insulating state to a conducting state in a thin layer of Alq3 sandwiched between two metal electrodes. Field-induced switching behavior with a high on-off ratio of ∼105 is observed in the devices, in which the cathode electrode is Al and the anode electrode is varied including Al, Au, and indium tin oxide. The switching behavior is absent in devices in which both electrodes have a high work function, indicating that efficient electron injection has an important role in the electric-field-induced switching behavior of Alq3-based single-layer devices.
Colloidal Sphere Formation, H-Aggregation, and Photoresponsive Properties of an Amphiphilic Random Copolymer Bearing Branched Azo Side Chains

This work studied the colloidal sphere formation, H-aggregation, and photoresponsive properties of an amphiphilic random copolymer functionalized with branched azo side chains (POAPB6P-AC). The colloidal spheres were prepared through gradual hydrophobic association of the polymer chains in THF−H2O media, which was induced by a continuous increase in the water content. The forming process and morphology of the colloidal spheres were characterized by DLS, SLS, and TEM. UV−vis spectroscopy was used to study the azo chromophore H-aggregation and structure variation in the colloid formation process by measuring the parameters such as λmax, the trans-to-cis photoisomerization rate, and the isomerization degree at the photostationary state. The results indicate that the colloidal sphere formation undergoes several different stages as the water content increases. The polymeric chains start to associate at the critical water content (CWC). CWC is related with the initial concentration of the polymer in THF and is .
Metal–organic interface and charge injection in organic electronic devices

Charge injection at the interface between metallic electrodes and organic semiconductors plays a crucial role in the performance of organic (opto-)electronic devices. This article discusses the current understanding of the formation of the metal–organic contact and the parameters which control the injection current. Organic semiconductors differ significantly from their inorganic counterparts, primarily because they are amorphous van der Waals solids. As a result the electronic states are highly localized, and charge transport is by site-to-site hopping. Organics can also form clean interfaces with many metals, free of interface states in the gap. Nevertheless, there is generally found to be a significant vacuum level offset, the origins of which are not yet fully understood. Organic semiconductors are frequently free of donor and acceptor dopants, and as a result the depletion depth is larger than the organic layer thickness. Thus the Fermi level in the organic and the charge injection barriers depend mo.
Properties and Interactions of Physigrafted End-Functionalized Poly(ethylene glycol) Layers

We have studied the properties of layers of end-functionalized poly(ethylene glycol) (PEG) grafted by one end to mica surfaces, and, using a surface force balance, the interaction between two such layers. PEG of molecular weight 3.4 kg/mol, functionalized at both ends with an N-hydroxysuccinimide carbamate (NHS) group, to form NHS−PEG−NHS, does not adsorb on mica. When a trimethylammonium group ((CH3)3N+) replaced one of the NHS groups to form ((CH3)3N+)−PEG−NHS, a surface layer formed on the mica from its aqueous solution, showing that the functionalized PEG had been attached by its (CH3)3N+ end. The properties of the ((CH3)3N+)−PEG−NHS layer were examined primarily by surface force measurements as well as by atomic force microscopy, contact angle measurements, and confocal fluorescence microscopy. The layer was found to be very smooth, and the NHS group was found to retain its reactivity also when attached to the surface, demonstrating that the end-functionalized PEG chains can be used as flexible surfa.
Infrared Emission Spectroscopic Study of Some Natural and Synthetic Paragonites

The infrared emission spectra of a synthetic paragonite have been compared to natural paragonites from Monte Campione (Switzerland) and Williamstown (Australia). The OH stretching region is characterized by a silanol band around 3745 cm−1, two Al–OH stretching bands around 3650 and 3627 cm−1, and a water band around 3450 cm−1. The low-frequency region is characterized by bands at 1185, 1075, 993, 917, 883, 819, 803, 750, 725, 622, 545, and 486 cm−1 ascribed to different Si–O stretching, Al–OH libration and bending, and Si–O and Si–O-AlVI bending modes. The natural paragonites show minor differences in band positions. In the spectra of the paragonite from Williamstown (Australia), bands at 883 and 725 cm−1 are missing, while a new band is observed at 521 cm−1 and the Si–O stretching bands are shifted towards higher wavenumbers. This result is ascribed to the presence of a muscovite component in the crystal structure of the paragonite, as is possible in the continuous compositional series muscovite–paragonite. Heating causes the dehydroxylation of the paragonite, as is evidenced by broadening, a shift towards lower wavenumbers, and a diminishing intensity of the bands associated with the various OH modes. No new bands were observed indicating the restructuring of the octahedral layer.

The Relationship between Intracranial Pressure and Visual Field Zones in Normal-Tension Glaucoma Patients

Growing evidence suggests that intracranial pressure (ICP) plays an important role in the pathophysiology of glaucoma, especially in normal-tension glaucoma (NTG) patients. Controversial results exist about ICP’s relationship to visual field (VF) changes. With the aim to assess the relationship between ICP and VF zones in NTG patients, 80 NTG patients (age 59.5 (11.6) years) with early-stage glaucoma were included in this prospective study. Intraocular pressure (IOP) (Goldmann), visual perimetry (Humphrey) and non-invasive ICP (via a two-depth Transcranial Doppler, Vittamed UAB, Lithuania) were evaluated. Translaminar pressure difference (TPD) was calculated according to the formula TPD = IOP − ICP. The VFs of each patient were divided into five zones: nasal, temporal, peripheral, central, and paracentral. The average pattern deviation (PD) scores were calculated in each zone. The level of significance p < 0.05 was considered significant. NTG patients had a mean ICP of 8.5 (2.4) mmHg. Higher TPD was related with lower mean deviation (MD) (p = 0.01) and higher pattern standard deviation (PSD) (p = 0.01). ICP was significantly associated with the lowest averaged PD scores in the nasal VF zone (p < 0.001). There were no significant correlations between ICP and other VF zones with the most negative mean PD value. (p > 0.05). Further studies are needed to analyze the involvement of ICP in NTG management.
Concentrations of Radiocarbon and Isotope Compositions of Stable Carbon in Food

The 14C activities and/or á13C values were measured for tree rings, rices, edible oils, flavors, beers, chickens and eggs. The 14C activity in 1999 ranged from 14.4 to 14.8dpm/g.C for those of tree rings and rices. The 14C activities of oils were in good agreement with the present atmospheric one. The 14C activities of flavors could differentiate petrochemically derived compounds from natural products. On the other hand, the Δ13C value could distinguish between C3 and C4 plants for the main ingredient of oils, flavors and beers. For chickens and eggs, & Delta;13C values reflected their diet. In addition, large variation of Δ13C values was observed among components of eggs.
Trace Metal Fractionation by the Sequential Extraction Method in Sediments from the Lis River (Portugal)

The extractable contents of Zn, Pb, Cu, Cr, Mn, Ni, Fe and Al were evaluated in sediments from the Lis River (Portugal) using the three-step sequential extraction procedure described by Community Bureau of Reference (BCR, now the Standards, Measurement and Testing Programme) of the European Union. The distribution of trace metals among the exchangeable, water and acid soluble, reducible, oxidizable and residual fractions was determined. The highest metal concentrations were observed in samples collected at the most polluted river sites (animal husbandry, domestic, industrial and agricultural wastes). Pb, Cu, Cr, Ni, Fe and Al were found mainly associated with the residual and organic fractions. High concentrations of Zn and Mn were found in the exchangeable/acid soluble fraction.
Infrared Intensities of Silane

The integrated intensities of the fundamental absorption bands of SiH4, SiD4, and SiD3H have been measured using the Wilson—Wells—Penner—Weber method. These data indicate that the derivatives of the molecular dipole moment with respect to the bond‐stretching and bond‐bending coordinates are of opposite algebraic sign.
Effect of Low Concentration Cyanide on Startup of Expanded Granular Sludge Bed for the Treatment of Tapioca Starch Wastewater

In this investigation, An Expanded Granular Sludge Bed (EGSB) was used to treat tapioca starch wastewater containing low concentration cyanide and the influence of cyanide concentration on the startup of EGSB reactor was conducted. On the condition of 13.4h of HRT, the chemical oxygen demand (COD) and cyanide concentration varied, The EGSB performance was assessed in terms of COD, pH, alkalinity, volatile fatty acids (VFA) and methane variation during the process. The results showed that cyanide was harmful to the anaerobic bacteria of the granular sludge in EGSB reactor for the treatment of tapioca starch waster, as the cyanide concentration was at 15mg/L, COD removal efficiency for cyanide free wastewater nearly 90%, however the efficient dropped to 80% with increasing cyanide concentration up to15mg/L; the methane production was nearly 200mg/L with cyanide concentration and dropped to a value of 2mg/L for 15 mg/L cyanide; and methanogenic activity decreased; while the influent VFA was increased, at an cyanide concentration of 0 and 5mg/L, the concentration of VFA was maintained below 100.00mg/L, but it was higher than 600mg/L in most of the cases with influent cyanide concentration of 15mg/L; SEM observation of the granules showed the predominance of Methanosaeta. sp. and the obvious damage of the bacteria located on the surface or in the inner part of some granules, leading to a deterioration of granular sludge settling velocity, and even some granules washed out.
Influence of Heat Treatment on the Volatile Compounds of Milk

In this work dynamic headspace capillary gas chromatography coupled with multivariate statistical techniques was applied to distinguish milks subjected to different heat treatments (pasteurization, direct ultrahigh-temperature method, and “in-bottle” sterilization). Results were obtained by taking into account a reduced, though significant, number of volatile compounds (acetone, 2-butanone, 2-pentanone, 2-heptanone, 3-methylbutanal, pentanal, hexanal, heptanal, dimethyl disulfide, toluene, and limonene). Moreover, the concentration of these volatile compounds, especially aldehydes and ketones, provided discriminant information about storage time and storage temperature in both whole and partially skimmed UHT milk. The analytical method was quite simple, rapid, and reliable and permitted the analysis of a large number of milks to be carried out by using a small volume of sample. This work represents an attempt to apply a method, generally used only for research purposes, to the quality assessment of heat-t.
Energetic and exergetic analysis of waste heat recovery from a microturbine using organic Rankine cycles

This article examines the exhaust waste heat recovery potential of a microturbine (MT) using an organic Rankine cycle (ORC). Possible improvements in electric and exergy efficiencies as well as specific emissions by recovering waste heat from the MT exhaust gases are determined. Different dry organic working fluids are considered during the evaluation (R113, R123, R245fa, and R236fa). In general, it has been found that the use of an ORC to recover waste heat from MTs improves the combined electric and exergy efficiencies for all the evaluated fluids, obtaining increases of an average of 27% when the ORC was operated using R113 as the working fluid. It has also been found that higher ORC evaporator effectiveness values correspond to lower pinch point temperature differences and higher exergy efficiencies. Three different MT sizes were evaluated, and the results indicate that the energetic and exergetic performance as well as the reduction of specific emissions of a combined MT‐ORC is better for small MT power outputs than for larger MTs. This article also shows how the electric efficiency can be used to ascertain under which circumstances the use of a combined MT‐ORC will result in better cost, primary energy consumption, or emission reduction when compared with buying electricity directly from electric utilities.

Spectroscopic Studies of Cu2+ Ions Doped in KZnClSO4 · 3H2O Crystals

EPR, optical absorption and infrared spectral studies have been performed on Cu 2+ ions doped in KZnClSO 4 . 3 H 2 O single crystals. The room temperature single crystal EPR spectra reveal the presence of two magnetically inequivalent Cu 2+ sites. The spin-Hamiltonian and molecular orbital parameters have been evaluated. The optical absorption spectrum at room temperature exhibits a broad band centred at 11900 cm -1 which has been assigned to the transition |3z 2 - r 2 > → |xz, yz>. The ground state wavefunction of Cu 2+ ions has been estimated and found to be predominantly |3z 2 - r 2 > with a slight admixture of |x 2 - y 2 >. The infrared spectra of KZnClSO 4 . 3 H 2 O have been also studied in the wavelength range 4600 to 400 cm -1 . The observed bands are assigned to the low symmetry sulphate ion and the coordination of water molecules in the lattice.
Toxic effects of titanium dioxide nanoparticles on reproduction in mammals

Titanium dioxide nanoparticles (nano-TiO2) are widely used in food, textiles, coatings and personal care products; however, they cause environmental and health concerns. Nano-TiO2 can accumulate in the reproductive organs of mammals in different ways, affect the development of the ovum and sperm, damage reproductive organs and harm the growth and development of offspring. The oxidative stress response in germ cells, irregular cell apoptosis, inflammation, genotoxicity and hormone synthesis disorder are the main mechanisms of nano-TiO2 toxicity. Possible measures to reduce the harmful effects of nano-TiO2 on humans and nontarget organisms have emerged as an underexplored topic requiring further investigation.
In situ spectroscopic ellipsometry study of the hydrogenation process of switchable mirrors based on magnesium-nickel alloy thin films

The hydrogenation process of switchable mirrors using magnesium-nickel alloy thin films including a thin palladium cap layer was analyzed by measuring the variation in ellipsometric angles Ψ and Δ using in situ spectroscopic ellipsometry. The process was divided into three phases and each phase was identified as follows. The first phase was the process in which the solid solution was formed because a Mg–Ni alloy in its metal state absorbs hydrogen. The second phase was the hydrogenation processes of the solid solution and the metal Pd layers. The third phase was the hydrogenation process of residual metal Pd in the Pd layer. In the initial state of the second phase, a hydride of the alloy was nucleated at the film/substrate interface as a result of hydrogenation of the solid solution, and a mixture layer of the hydride and solution was formed. With proceeding hydrogenation, the thickness of the mixture layer increased and the homogenous hydride layer was afterwards formed at the film/substrate interface.
AN EXPERIMENTAL EVALUATION OF THE GOVERNING MOISTURE MOVEMENT PHENOMENA IN THE PAPER COATING PROCESS. I. THEORETICAL ASPECTS

The most important issue when coating paper is the modelling of the moisture movement in the coating process, since the water movement pattern is strongly connected to binder movement and the final structure of fibres and coating colour, which in turn affects the final printing properties of the paper. Therefore, we are now studying a novel laboratory method to determine the dynamic water movement in a hygroscopic porous media, i.e. the liquid movement in the paper coating process. The experimentally determined physical properties yield information relevant to the mass and energy balances of a real paper coating process. We have also studied the widely used Lucas-Washburn capillary suction theory in combination with the build-up of a filter-cake in the coating colour. The study shows, that the water loss from the coating colour into a hygroscopic material can be well explained by applying vapour diffusion into the base paper as the governing mass transfer mechanism.
Antitumour ether lipids: proapoptotic agents with multiple therapeutic indications

Synthetic ether-linked analogues of phosphatidylcholine, collectively referred to as antitumour ether lipids or synthetic antitumour lipids (ATLs), are a versatile class of structurally-related and pharmacologically active alkylphospholipids with manifold biomedical applications that are able to kill tumour cells and protozoan parasites. This cytotoxic action of ATLs relies on their ability to affect signalling processes, inducing apoptosis in the target cell. ATLs comprise two subfamilies of compounds, namely: i) the so-called alkyl-lysophospholipid analogues or alkyl ether phospholipids, exemplified by edelfosine, which shows a selective antitumour action through a unique mechanism of action by intracellular activation of Fas/CD95 death receptor and its co-clustering with membrane rafts; and ii) the alkylphosphocholines (APCs), exemplified by miltefosine, which has become the first orally-effective treatment for visceral leishmaniasis. New clinically promising APC members include perifosine and erucylphosphocholine. Additional ATL therapeutic indications include multiple sclerosis, autoimmune and inflammatory diseases, as well as psoriasis and viral infections. This review summarises the evidence and patented information supporting major ATL biomedical uses.
