This paper aims to describe and evaluate the proposed calibration model based on a neural network for post-processing of two essential meteorological parameters, namely near-surface air temperature (2 m) 24 h accumulated precipitation. The main idea behind this work is improve short-term (up 3 days) forecasts delivered by global numerical weather prediction (NWP) called ECMWF (European Centre Medium-Range Weather Forecasts). In comparison existing local models that typically provide limited...

Prediction of electricity energy consumption plays a crucial role in the electric power industry. Accurate forecasting is essential for supply policies. A characteristic feature electrical need to ensure constant balance between and production, whereas cannot be stored significant quantities, nor it easy transport. Electricity generally has stochastic behavior that makes hard predict. The main goal this study propose models predict maximum hourly per day more accurate than official load...

Membrane electrodes selective to bupivacaine cations were developed and those with PVC-dibutylphthalate membrane containing sparingly soluble phosphotungstate appeared be the most suitable. Inclusion complexation of cyclodextrins was studied by potentiometric measurements free cation concentration in aqueous solutions hydrochloride cyclodextrin using prepared electrodes. Native alpha-cyclodextrin (alpha-CD) beta-cyclodextrin (beta-CD), as well their random-substituted derivatives...

The development of an economy and, in particular, the construction new infrastructure as well industrial enterprises creates demand for road transport oversized freight that exceeds maximum permissible total mass vehicle combinations with its share on axles. Failure to comply defined technological processes and a deficiency assessment permitting such forms transportation can have large adverse effect, predominantly lifetime bridges network, which international implications well. There is no...

Car drivers have been suffering from road bottlenecks due to the constant increase in number of vehicles that are not matched by growth network. Obstacles on a or narrowed one bidirectional an accompanying phenomenon congested transport This paper solves queueing system generated such bottleneck managed traffic lights. Generally, problem can be classified as Semi-Markov process with stochastic arrivals and deterministic service queue appropriate length. In order, allow for analytical...

The critical micellar concentrations ( cmc ) of the title cationic surfactants were measured in aqueous solutions at 25 °C presence KBr, KF, KCl, KI, KSCN, KNO 3 , KAc and HCOOK. conductometric and, part, potentiometric methods employing ion selective electrodes used. For 1-cetylpyridinium bromide absence any electrolytes, decreasing temperature dependence was conductometrically over region 12 - 40 association degree micelles with Br anions calculated. decrease two due to electrolytes (in up...

Inclusion complexation of an antimicrobial quaternary ammonium salt, carbethopendecinium bromide (SBr, Septonex), with five cyclodextrins was investigated potentiometrically using the prepared membrane electrodes selective to surface-active cations (S + ). Relatively strong S native α-cyclodextrin (α-CD), β-cyclodextrin (β-CD), and their random-substituted derivatives, namely hydroxypropyl-α-cyclodextrin (HP-α-CD), methyl-β-cyclodextrin (M-β-CD), hydroxypropyl-β-cyclodextrin (HP-β-CD),...

Abstract The demand for public transport by tourists increases significantly in tourist-attractive destinations. This is addition to regular passengers commuting school and work. level of irregular influenced several factors related the characteristics day week, period year, current weather. main goal paper verify which most influence a area ensure operational planning passenger transport. Thanks this, it possible sufficient capacity and, at same time, efficiency operation analyzes...

Micellization of the local anesthetic drug carbisocaine hydrochloride (BHCl) was studied by potentiometry with both cation- and anion-selective membrane electrodes in aqueous solution at 25 °C. The found critical micelle concentration 0.022 mol dm -3 course free cation chloride counterion micellar corresponded to characteristic cationic surfactants. In a more dilute solution, below concentration, complexation BH + α-cyclodextrin (α-CD), β-cyclodextrin (β-CD) its random substituted methyl...

Airspace domain may be represented by a time-space consisting of three-dimensional Cartesian coordinate system and time as the fourth dimension. A provides scheme for locating points given its coordinates vice versa. The choice is important, it transforms data to geometric representation. Visualization three more dimensional on two-dimensional drawing - computer monitor usually done projection, which often can restrict amount information presented at time. Using parallel one possibilities...

Reducing greenhouse gas (GHG) emissions has become a necessity and not an option to sustain the environment in both human natural systems.The Slovak Republic (SR), like European Union (EU), aims neutral by 2050.To reach this ambitious target, will need fall 55% compared those base year 1990.Therefore, forecasting GHG emission amounts is important.The grey model one of widespread mathematical methods.There exist studies that have used some types models predict but case Republic.We optimized...

The conventional activity of chloride ions was measured by an ion-selective electrode at 25 °C in aqueous solutions benflurone, i.e. 5-(2-(N,N-dimethylamino)ethoxy)-7-oxo-7 H -benzo(c)fluorene hydrochloride, without or with additions KCl. These results suggest a gradual association benflurone; the formation hetero-associate, (BH + ) 2 Cl - , followed higher associates evaluated range up to 0.1 mol l -1 .
