    Opis:
    Manufacturing engineering is supposed to provide analyses related to various aspects of manufacturing and production in order to maximise technological, energy, and economic gains in relevant production processes. The present paper gives a recapitulation of several publications by present authors, presenting considerations of the energy efficiency of biofuel production. The energy efficiency is understood as the ratio of energy obtained from biofuels produced basing on crops from a particular area to the energy required to satisfy needs of all subsidiary processes assuring correct functioning of the production system, starting from operations aimed to obtain agricultural crops, and ending with the conversion of the crops onto biofuels. Derived by the present authors, the mathematical model of energy efficiency of biofuel production is extended to a more general form, and applied to the analysis of quantitative relations between energy efficiency of sc. “energy plantations”, and further elements of biofuel production system converting harvested biomass into biofuel. Investigations are aimed towards the determination of the role of biomass as a source of energy.

    Opis:
    Designing of storage facilities is an interdisciplinary process that requires consideration of technical, economic, social or environmental issues. Storage facilities, as a part of supply chain are designed to provide customers availability of goods at a certain time, quantity and place. This involves the functions resulting therefrom, such as storage, sorting, picking, packing, etc. The efficiency of processes in the supply chains is strongly influenced by the location and shape of the storage facilities that are critical components. These issues are multi-threaded, and they are subject of an iterative approach in which information tools are playing a special role. One of such tool is the SIMMAG3D system. It is a system for modelling and visualization in 3D of warehouse facilities, which was built based on developed mathematical models, computational algorithms and functional dependencies necessary for the designing of storage facilities. It also takes into account the different types of warehouses and design methodologies as well as the location of warehouses in the logistic network. The article presents the elements of the SIMMAG3D system and characterizes its functional capabilities. It has been pointed out that one of the key elements of the system is the module for 3D visualization of storage facilities. In addition, an example of the visualizer operation on real data concerning one of the FMCG storage facility is provided.

    Opis:
    The aim of the study was to characterise the microstructure of 35CrSiMn5-5-4 steel which was subjected to a new heat treatment technology of quenching and partitioning (Q&P). The parameters of the treatment were chosen on the basis of computer simulations and dilatometric studies of phase transformations occurring in steel. The transmission electron microscopy (TEM) observations of steel microstructure after the Q&P treatment revealed the presence of martensite as well as significant amount of retained austenite in form of layers between the martensite laths. The rod-like carbides in the ferritic areas were also observed, which indicates the presence of lower bainite in steel. It was found that the retained austenite content measured by means of TEM was about 28% for partitioning at 400°C and 25% for partitioning at 260°C. These results are in good agreement with the phase composition calculated theoretically as well as those determined experimentally by use of dilatometric tests.

    Opis:
    This paper presents the results of a numerical analysis of nitride-based edge-emitting lasers with an InGaN/GaN active region designed for continuous wave room temperature emission of green and blue light. The main goal was to investigate whether the indium thin oxide (ITO) layer can serve as an effective optical confinement improving operation of these devices. Simulations were performed with the aid of a self-consistent thermal-electrical-optical model. Results obtained for green- and blue-emitting lasers were compared. The ITO layer in the p-type cladding was found to effectively help confine the laser mode in the active regions of the devices and to decrease the threshold current density.
