For many companies, the process of new product development is a key activity determining a competitive advantage. Rapid technological changes, demand uncertainty, customization of products and focusing on core competencies means today a need for early involvement of suppliers in product development projects to reduce costs, shorten time to market of new solutions and improve product quality. Such...
Approximately 80% of the world trade and about 70% of transport is by sea and is handled at terminals of seaports. The article describes the reasons for the increase in operating costs of maritime transport, drawing the attention to the sources of cost increases and their size. The main factor is the dynamic rise of fuel prices, followed by personnel, insurance and supplies costs. The research carried...
The aim of this paper is presentation of research results connected with attitude companies to specialize in refrigerated transport area to the point of perfection of quality logistics services. The study of quantitative character was conducted using of survey method based on a questionnaire survey. Entities participating in the study were companies providing the refrigerated transport services. The...
The article describes the use of mobile technology in logistics. Presented operating systems for mobile devices. Mentioned the subject of application described in storage technology. Also shows the geographical identification technology is widely used in modern companies.
One of the most difficult problems in construction is to take objective decision, especially for selection of roads for modernisation and safety improvement. Decision making process is very complicated and time consuming (due to the complex nature of construction projects). Many experts, with extensive knowledge of Construction Industry, take subjective decisions, related to verbal methods of decision...
It is a well-known fact that nowadays railway vehicles are designed and manufactured on much higher standard than older vehicles, many of them of obsolete concepts. On the other hand, nowadays railway vehicles designs are more complex and require much higher investment costs. Efforts to minimise costs and demonstrate the economic advantages of these new technologies and designs, throughout the life...

This paper provides brief characteristic of marine environment including Arctic area with rich oil and resources Basic information is given for most common types of offshore installations with emphasis on ice-resistant Arctic rigs. Two types of vessels performing...
Ze względu na szybki wzrost liczby urządzeń mobilnych, takich jak smartfony czy tablety, coraz łatwiejsze staje się wyznaczenie trasy między dwoma punktami lub po prostu zlokalizowanie wybranych pozycji przy użyciu tych urządzeń. Tworzenie tego rodzaju aplikacji jest bardzo łatwe, ponieważ deweloperzy mają do dyspozycji szeroki zakres oprogramowania i narzędzi je wspomagających, takich jak: nowoczesne...
This paper deals with description of operation behaviour of various friction materials of brake blocks (cast iron and composite) of railway brakes with regard to braked wheels. Rim of the wheel is exposed to thermal loading during the braking process. The thermal loading depends on material of used brake blocks. The mechanical and thermal loading of the wheels results in various stress in its rim...
It is shown that every positive fractional descriptor electrical circuit is a descriptor linear system with regular pencil. The pointwise completeness and pointwise degeneracy of these electrical circuits are analyzed by the use of the method based on Drazin inverse of matrices. Conditions for the pointwise completeness and pointwise degeneracy of the electrical circuits are established and illustrated...
Results of tests of training-ship model’s free rolling have been presented in the elaboration. The research was conducted on the laboratory stand of the Naval Academy. Paper presents the description of the laboratory and results of rolling. The first stage of research is limited only to the immersion testing the ship model. The results recorded during the study are presented in the paper.
Queueing systems are widely used in different fields of actual functioning with assumption that the arrival process is not correlated and has independent increments, Although it is associated with simple and more tractable form of statements, this can lead to inaccurate modeling and performance evaluation of analyzed process. In this article a more realistic attempt to examine the single lane traffic...
The paper refers to threat assessment of dangerous goods in road transportation of the Republic of Poland. DGV can cause an accident and lead to fires, explosions and chemical poisoning or burning with considerable harm to people and the environment. There is not monitoring system in Poland to control in real time road transportation of dangerous goods. Consortium of Motor Transport Institute, Telecommunication...

The aim of this article is the discussion of land use by the intermodal transshipment hub for the implementation of the adopted technology operations. Terminal size has an impact on the energy consumption of machines operating there and directly affects the start-up costs of the project. Despite much discussion of the application of different handling techniques has not considered the problem of land...
The paper presents the purpose of using the eye-tracker, as well as points the main area of its eye-tracking data application in driving experiments. The review of related works on driver visual and cognitive load is presented and discussed. The method and results from pilot study aimed to examine the possibility of usage of head-mounted eye-tracker (SMI Eye Tracking Glasses 2.0) to collect eye movement...
Fully-electric vehicles is a relatively fast growing segment of the automotive industry. Still there are many issues related to the shortcomings of electric vehicles that still need to be addressed. One of the main concerns is the limited range that results from the capacity of batteries and the consumption rate of electrical energy spent on driving and using the on-board auxiliaries. Project EMERALD...
In the paper authors would like to present practical application of Ship Energy Efficiency Management Plan on the base of implemented SEEMP in one of tankership company. Authors presented possible measures for improvement of energy efficiency, monitoring methods and on board vessel evaluation of effectiveness of SEEMP.
The present work is focused on a comparative experimental study for determining the effect of fuel properties of oxygenated fuels on selected work parameters of direct injection (DI) diesel engine. The engine was operated on fossil diesel oil (DO), biodiesel (BD also known as FAME) and biodiesel with 10% and 20% ethanol addition, accordingly (ET10) and (ET20). Each of the fuels were tested at steady...
