The technological model of operating area by the combined transport

The contribution deals with design technology service model using the combined transport. It assesses the performance indicators in relation to price and quality of services provided and on this basis decides on the type of the transport. This is the decision-making processes, which should answer the question, whether used directly in road freight transport, direct rail freight transport or combined transport. In this contribution is the combined transport meant as a system between the conventional modes, which are transhipped goods from road vehicles to the rail cars or river boats

1-Methane­sulfonyl-1H-1,2,3-benzotriazole

The mol­ecular geometry of the title compound, C7H7N3O2S, does not differ much from that of the previously reported 4-toluene­sulfonyl analogue. Unlike the latter compound, however, mol­ecules of the title compound associate primarily via π–π stacking inter­actions of their benzene rings [centroid–centroid distance = 3.5865 (8) Å], forming columnar stacks along the crystallographic 21 axes. These stacks are inter­connected via weak C—H⋯O and C—H⋯N hydrogen bonds

THE OPTIMALIZATION OF LOCATION TRANSPORT JUNCTIONS

Tento článek je zaměřen na problematiku lokace dopravních uzlů na dopravní síti, s využitím moderních optimalizačních algoritmů. Hlavní důraz je kladen na využití genetických algoritmů, které pracují na principu umístění s jednoduchým hubem bez omezení kapacity a simulaci evolučních procesů použitých na dopravních uzlech.This article is focused on the issue of deployment of transport junctions and other transport network, using modern optimization algorithms. The main emphasis is placed on genetic algorithm operating on the principle of location with simple hub allocation without capacity constraints and simulation of evolutionary processes applied to the transport nodes

Modelling of transport services in the selected area using city logistics

Disertační práce se zabývá problematikou řešení svozně-rozvozního problému s obsluhou vrcholů definovaných na městské dopravní síti. Práce vychází ze zahraničních přístupů pro řešení obsluhy v citlivých městských zónách. Zaměřena je na zásobování prostřednictvím městského distribučního centra, dále jsou stanoveny omezující podmínky pro obsluhu a v rámci řešení je využito Clarke-Wrightovy metody pro sestavu okružní jízdy. Její výsledky jsou porovnány s výstupy z programu NetOpt.The thesis is focused on solving of the Vehicle Routing Problem, which is defined in the urban transport network. The work is based on international approaches to address service in urban zones. It focuses on urban supplies through the distribution centre, there are also restrictive conditions set for operator and for solution is used Clarke-Wright method. The results are compared with outcomes of Net Opt program.Katedra technologie a řízení dopravyPrezentace dizertační práce. Posudky, odpovědi na připomínky oponentů. Vědecká rozprava.

LOGISTIC TECHNOLOGY AND THE CITY LOGISTICS

Due to the increasing customer demands for quality traffic, increasing transport volumes and diverse range of possible technologies, logistics provides solutions in freight transport. This article focuses on logistics and information technology, market principles and new trends in the City logistics. Currently, it is important to solve the transport service in the City logistics, distribution models which are a guarantee of new opportunities for optimization of transport in urban areas

Measurement of HGB beer colloidal ageing and tannoid content development using complex turbidimetric analysis.

Measurements of HGB beers were carried out in concentrated and blended samples to analyse the chill haze and tannoid content development during the thermal forced ageing process. The measurements were performed by the method of complex turbidimetric analysis (CTA), based on a single instrumentation for beer chill haze determination in commercial bottles and polyvinylpyrrolidone/tannoid content titration of beer samples in usual reaction tubes. For illustration of the efficiency of the CTA method, the initial values of saturated ammonium sulphate precipitation limits (SASPL) and sensitive protein (SP) levels were determined, too. The CTA method confirmed enhanced colloidal stability of the blended HGB final product due to lower content of the high molecular weight haze active proteotannic complexes. An almost linear correlation between the chill haze and tannoid content development during beer ageing process, starting from some concentration threshold level after a certain lag time was revealed.The correlation between the tannoid content of HGB beer in blended and non blended state was found also linear. The CTA method can be effectively used for the evaluation and prediction of the HGB beer colloidal ageing process and diagnostics of the causes of production inhomogeneity.Measurements of HGB beers were carried out in concentrated and blended samples to analyse the chill haze and tannoid content development during the thermal forced ageing process.
