Soil organic matter (SOM) is a key factor for evaluating soil fertility. Rapidly monitoring content in desert can provide scientific basis the rational development and utilization of reserve arable land resources. Although spectral inversion accuracy SOM under laboratory-controlled conditions high, it time-consuming costly compared to situ spectroscopic determination method. However, spectrosco...

In this paper an architecture for the recognition of d)inamic gestures is described. The system implemented is designed to take a sequence of images and to assign it to one of a number of discrete classes where each of them corresponds to a gesture from a predefined vocabulary. The classijication task is broken down into an initial preprocessing stage following by a mapping from the preprocesse...

In this paper we analyze comparatively the macroeconomic performance of different Central and Eastern European countries by the means of Data Mining (DM) techniques. We analyze the economic situations of three EU countries (Poland, Slovenia and Latvia), a newlyaccepted one (Romania), and other two non-EU countries (Russia and Ukraine). We have depicted economic performance of countries using a ...

permeability can be directly measured using cores taken from the reservoir in the laboratory. due to high cost associated with coring, cores are available in a limited number of wells in a field. many empirical models, statistical methods, and intelligent techniques were suggested to predict permeability in un-cored wells from easy-to-obtain and frequent data such as wireline logs. the main obj...

Vad kännetecknar en text av god kvalitet och hur starkt påverkar textens utformning, sammansättning och uppbyggnad ifall en avhandling eller rapport uppfattas som högkvalitativ? Dessa frågor har aktualiserats med anledning av Högskoleverkets utvärderingssystem av utbildningar, som lägger stor vikt vid skriftliga rapporter producerade i samband med examensarbeten. Detta nummer av Lärande i LTH h...

Background and objectives: Attenuated total reflectance-inferared (ATR-IR) spectra can be used as a non-invasive fingerprinting approach in quality control of herbal samples. Methods: Twenty versatile herbal samples were subjected to attenuated total reflectance-inferared (ATR-IR) spectroscopy followed by different clustering methods in order to determine by which method more reasonable classif...

Yores hensigt vil her va::re at konstruere dele af et direkte afbildende sprog, som vil sa::tte os i stand til at repra::sentere virkelighedens mest generelle strukturer. Vi skal ikke her benytte os af de logiske standard-behandlinger af epistemiske tilstande, der sa::dvanligvis opfatter disse som domme (propositioner). Vi vil i stedet genoptage den ikke mindre a::rva::rdige, men nutildags noge...

Extraction of soil organic matter (SOM) fractions has been a longstanding approach to elucidating the pivotal roles of SOM in soil processes. Several types of extraction procedures are commonly used, and all provide partial information on SOM function. This report and accompanying papers summarize the information regarding SOM functions in real-world issues that has been gained through physical...

With the increase of computer usage, the number of digital documents is reaching values that make unviable conducting the tasks of text organization by humans. There is a demand for text organization tools that can operate with little human intervention and that can display the results of the organization in the most commonly used visual interface: the two-dimensional (2D) plane. One of the tec...

Cortical GABAergic interneurons represent a highly diverse neuronal type that regulates neural network activity. In particular, interneurons in the hippocampal CA1 oriens/alveus (O/A-INs) area provide feedback dendritic inhibition to local pyramidal cells and express somatostatin (SOM). Under relevant afferent stimulation patterns, they undergo long-term potentiation (LTP) of their excitatory s...
