different conservation tillage practices are nowadays suggested as the best solution for prevention of soil from erosion. this could be done by leaving the previous crop residue on the soil surface. a new idea to plant in the conservation tillage system is the use of punch planters by which one can plant through a heavy depth of previous crop surface residue. the study was conducted using a 2?3...

In the basis of contemporary portfolio theory is Markowitz model analysis which accurately defines a set efficient portfolios for relatively small number securities in its composition. With increase portfolio, application Markowitz's becomes complex, so financial found solution problem single-index Sharpe's model. The later emergence multi-index models, better reflect reality, increased precisi...

This paper introduces a combining classifier using two proposed precision indexes: precision index (PIN) and class specific precision index (PIC). Comparison of combining methods typically fails to consider high precision performance. This new combining method generates predictions with higher precision and recall than other methods. The proposed method is especially useful for efficient screen...

This paper discusses the comparison between two kinds of features in clustering of some literary poems by the same author, the Romanian poet, Mihai Eminescu. Using Precision, Recall, Rand Index, Relative Precision and Purity measures we conclude that the topics of poems are better characterized by the phonemes as features than by geometric properties (described by six indicators: V/N ;A; Λ;V ar...

Dance video is one of the important types of narrative videos with semantic rich content. This paper proposes a new meta model, Dance Video Content Model (DVCM) to represent the expressive semantics of the dance videos at multiple granularity levels. The DVCM is designed based on the concepts such as video, shot, segment, event and object, which are the components of MPEG-7 MDS. This paper intr...

The vastness of clinical data and the progressing specialization of medical knowledge may lead to misinterpretation of medication efficacy. To show a realistic perspective on drug efficacy we present meta-analyses on some of the most commonly used pharmacological interventions. For each pharmacological intervention we present statistical indexes (absolute risk or response difference, percentage...

The motor cortex and the corticospinal system contribute to the control of a precision grip between the thumb and index finger. The involvement of subcortical pathways during human precision grip remains unclear. Using noninvasive cortical and cervicomedullary stimulation, we examined motor evoked potentials (MEPs) and the activity in intracortical and subcortical pathways targeting an intrinsi...
