A multi-criteria evaluation system for arable land resource assessment

2020

This study proposed a multi-criteria evaluation system for arable land resources by combining the soil integrated fertility index (IFI) with a soil cleanliness index (based on heavy metals and metalloid content). A total of 16 typical arable land units in Chongming District, China, were evaluated using the proposed evaluation system based on 104 collected soil samples in 16 towns. The comprehensive soil evaluation scores of arable lands in 16 towns were in the range of 90.7 to 99.2 with a mean of 96.2, indicating that the arable land in all 16 towns was at the level of excellent (≥ 90.0). Lower cleanliness indices had a significant impact on the final evaluation score. In comparison with si…

Channel Switching Protocols Hinder the Transition to IP World: The Pentagon Story

2019

In this paper, we target the strategy for telecommunications architectures during the transition to the IP-only models. The paper discusses the shifting from circuit switching to packet switching in telecommunications. Particularly, we analyze the coexistence of circuit switching and packet switching technologies in American military communications where each warfare object should have own IP address. The paper discusses the role of multifunction Soft Switches (MFSS). This Soft Switch plays the role of a media gateway between TDM channels and IP channels. As a case, we are passing through the transformation from SS7 signaling to internet protocol, ISDN-based government Defense Red Switch Ne…

Characterisation of clayey raw materials for ceramic manufacture in ancient Sicily

2011

Abstract It is well known that mineralogical, petrographic and chemical analyses can successfully support provenance studies of archaeological ceramics. The characterisation of a ceramic paste, the assessment of its technology of production and its provenance assignment related to a specific production centre or to a geographical and/or compositional space, are all tasks that can be performed even more accurately if the clayey raw materials used in pottery production are also studied. For that reason the identification of the clay deposits exploited in a given ceramic workshop often plays a key role in the archaeometric reconstruction of the production cycle where geology, mineralogy, petro…

THE INFLUENCE OF CHROMATIC ABERRATION ON DEMOSAICKING

2014

International audience; The wide deployment of colour imaging devices owes much to the use of colour filter array (CFA). A CFA produces a mosaic image, and normally a subsequent CFA demosaick-ing algorithm interpolates the mosaic image and estimates the full-resolution colour image. Among various types of optical aberrations from which a mosaic image may suffer, chromatic aberration (CA) influences the spatial and spectral correlation through the artefacts such as blur and mis-registration, which demosaicking also relies on. In this paper we propose a simulation framework aimed at an investigation of the influence of CA on demosaicking. Results show that CA benefits de-mosaicking to some ex…

Rigorous Multimode Equivalent Network Representation of Multilayer Planar Circuits

2018

The objective of this paper is to extend the use of the Multimode Equivalent Network formulation, originally developed to analyze waveguide junctions, to the analysis of planar circuits that include arbitrary rectangular printed, zero thickness metallizations together with internal and external ports in the transverse plane. The theoretical derivations lead to an accurate and computationally efficient tool for the analysis of boxed, multilayer microwave printed circuits. In addition to theory, the tool developed is used here to analyze two practical examples: a dual-bandpass and a 4-pole bandpass boxed microstrip filters. Good agreement with respect to commercial software tools and measurem…

Threats and attitudes toward Russian-speaking immigrants: a comparative study between younger and older Finns

2014

Using integrated threat theory as a theoretical lens to detect negative attitudes toward minority groups, this study compares and contrasts the perceptions and attitudes of older and younger Finns toward Russian-speaking minorities in Finland. A sample of high school students between 16 and 20 years of age represented the younger generation, while individuals over 65 years of age represented the older generation. The total sample was 242. Results indicated that there is a positive correlation between threat perception and prejudice. Results revealed that both groups have prejudices against Russian speakers and that these prejudices are related to the perception of realistic threat and negat…

LE AREE INTERNE PER LO SVILUPPO DEL TERRITORIO E LA COMPLEMENTARITÀ DI PROGRAMMI E STRUMENTI FRA LE POLITICHE EUROPEE DI SVILUPPO RURALE E DI COESIONE

Le Aree Interne rappresentano un tema particolarmente importante per la programmazione e la spesa dei fondi comunitari nel periodo 2014-2020 perché costituiscono il più grande esempio di complementarità fra le Politiche europee di sviluppo rurale e di coesione. Per lo sviluppo di queste Aree è stata creata una Strategia Nazionale per le Aree Interne (SNAI) che mira alla valorizzazione ed al recupero di tutti quei territori (rurali, montuosi, svantaggiati) dal carattere marginale rispetto alla disponibilità e all’offerta di servizi essenziali. La peculiarità di tale Strategia è quella di promuovere lo sviluppo di aree che sono uniformemente distribuite in tutto il comprensorio nazionale a di…

COMPREHENSIVE TEACHER’S PROFESSIONALISM FOR CONTENT AND LANGUAGE INTEGRATED PROVISION

2019

T opicality of the problem is determined by several factors as well as the amendments on the Education Law and the General Education Law, which provide for a gradual transition to the acquisition of general secondary education in Latvian only, educational content reform and teachers experience to work in an ethnically and linguistically heterogeneous environment. The aim of the study is to analyse comprehensive school teachers theoretical background and practice experience to work in the content and language integrated teaching and learning approach. Because language not a subject only but a mean of acquiring other subjects in the comprehensive school, too, all teachers need theoretical kno…

Continuous Monitoring of Parasitic Elements in Boost Converter Circuit

2021

The given paper explains the necessity of condition monitoring for DC/DC boost converter circuit. Further, an analytical model of circuit parasitic estimation is presented based on measured quantities in the circuit. The implementation of continuous estimation of circuit parasitic elements is analytically explained and verified by simulations and experimental results. Obtained results are acceptable for condition monitoring.

Multiprocessor SoC Implementation of Neural Network Training on FPGA

2008

Software implementations of artificial neural networks (ANNs) and their training on a sequential processor are inefficient because they do not take advantage of parallelism. ASIC and FPGA implementations employ specific hardware structures to exploit parallelism in order to improve processing speed; however, optimizing resource usage requires the use of fixed-point arithmetic, thereby losing precision, and the final system is restricted to a particular network topology. This paper presents a mixed approach based on a multiprocessor system-on-chip (SoC) on a FPGA. The use of software-driven embedded microprocessors with custom floating-point extensions for ANN related functions allows for gr…
