Status Resistensi Aedes Aegypti pada Kelurahan Endemis dan Non Endemis Db/dbd di Kabupaten Semarang terhadap Permethrin 0,25%

The resistance of Aedesaegypti to permethrintypes insecticides is one of the problems for controlling DHF / DBvector. Aedesaegypti in the city of Semarang and Salatiga adjacent to Semarang Regency has reportedly been resistant to permethrin. This research uses queasy research experiment with method of susceptibility test. It performed on purpose to see the resistance status of Aedesaegypti populations in the DB / DHF endemic villages (Semarang Regency) which immediately adjacent to the city of Semarang and two comparator areas, namely the Karangjati Village comparator (DBD endemic area), Diwak Village (non-endemic area). Data analysis performed using ANOVA showed the highest death average of mosquito on endemic areas 2 i.e. 11.8 (58.8%) and the lowest on the endemic area 1 i.e. 8.1 (40.6%). Based on ANOVA test, there was no difference on the whole resistance status. Under the provisions of the WHO, on the whole mosquito vector origin Semarang regency was resistant to permethrin 0.25% (mortality <80%). It is recommended that the same research was conducted with study on type and content of agriculture insecticides and household insecticides used in the research site

Time series analysis for minority game simulations of financial markets

The minority game (MG) model introduced recently provides promising insights into the understanding of the evolution of prices, indices and rates in the financial markets. In this paper we perform a time series analysis of the model employing tools from statistics, dynamical systems theory and stochastic processes. Using benchmark systems and a financial index for comparison, several conclusions are obtained about the generating mechanism for this kind of evolut ion. The motion is deterministic, driven by occasional random external perturbation. When the interval between two successive perturbations is sufficiently large, one can find low dimensional chaos in this regime. However, the full motion of the MG model is found to be similar to that of the first differences of the SP500 index: stochastic, nonlinear and (unit root) stationary.Comment: LaTeX 2e (elsart), 17 pages, 3 EPS figures and 2 tables, accepted for publication in Physica

Relational Knowledge Extraction from Attribute-Value Learners

Bottom Clause Propositionalization (BCP) is a recent propositionalization method which allows fast relational learning. Propositional learners can use BCP to obtain accuracy results comparable with Inductive Logic Programming (ILP) learners. However, differently from ILP learners, what has been learned cannot normally be represented in first-order logic. In this paper, we propose an approach and introduce a novel algorithm for extraction of first-order rules from propositional rule learners, when dealing with data propositionalized with BCP. A theorem then shows that the extracted first-order rules are consistent with their propositional version. The algorithm was evaluated using the rule learner RIPPER, although it can be applied on any propositional rule learner. Initial results show that the accuracies of both RIPPER and the extracted first-order rules can be comparable to those obtained by Aleph (a traditional ILP system), but our approach is considerably faster (obtaining speed-ups of over an order of magnitude), generating a compact rule set with at least the same representation power as standard ILP learners

Unravelling the contributions of motor experience and conceptual knowledge in action perception: A training study

Prior knowledge affects how we perceive the world and the sensorimotor system actively guides our perception. An ongoing dispute regards the extent to which prior motor knowledge versus conceptual knowledge modulates the observation of others’ actions. Research indicates that motor experience increases motor activation during action perception. Other research, however, has shown that conceptual familiarity with actions also modulates motor activation, i.e., increased motor activation during observation of unfamiliar, compared to conceptually familiar, actions. To begin to disentangle motor from conceptual contributions to action perception, we uniquely combined motoric and conceptual interventions into one design. We experimentally manipulated participants’ experience with both motoric skills and conceptual knowledge, via motor training of kinematically challenging actions and contextual information about the action, respectively, in a week-long training session. Measurements of the effects on motor activity measured via electroencephalography (EEG) during pre- and post-training action observation were compared. We found distinct, non-interacting effects of both manipulations: Motor training increased motor activation, whereas additional conceptual knowledge decreased motor activation. The findings indicate that both factors influence action perception in a distinct and parallel manner. This research speaks to previously irreconcilable findings and provides novel insights about the distinct roles of motor and conceptual contributions to action perception

Local dimension and finite time prediction in spatiotemporal chaotic systems

We show how a recently introduced statistics [Patil et al, Phys. Rev. Lett. 81 5878 (2001)] provides a direct relationship between dimension and predictability in spatiotemporal chaotic systems. Regions of low dimension are identified as having high predictability and vice-versa. This conclusion is reached by using methods from dynamical systems theory and Bayesian modelling. We emphasize in this work the consequences for short time forecasting and examine the relevance for factor analysis. Although we concentrate on coupled map lattices and coupled nonlinear oscillators for convenience, any other spatially distributed system could be used instead, such as turbulent fluid flows.Comment: 5 pagers, 7 EPS figure

Analisis Perbandingan Perencanaan Tebal Perkerasan Jalan Lentur Menggunakan Beberapa Metode Bina Marga Studi Kasus: (Ruas Jalan Piringsurat – Batas Kedu Timur)

Manual guidance highway pavement design issued by Directorate Jenderal Bina Marga is the result of modification to the rules of some developed countries such as AASHTO owned by United States and AUSTROADS owned by Australia. Then, the guidelines are adjusted to the condition of Indonesia to become an official guidelines that serve a reference for planning of highway pavement thickness in Indonesia.In this research, the study and the evaluation using four highway flexible pavement design guidelines starting from 2002 (Pt. T-01-2002-B) up to the latest guidance published in 2013 (No.02/M/BM/2013) with the case study Piringsurat – Batas Kedu Timur road segment. Use data as well as some of the same parameters in pavement design, in order to facilitate the conduct comparisons as traffic growth figures (i) 2,5% before 2020 and 3,5% after 2020. The result of flexible pavement thickness of four methods according to the flexible pavement design guidance, compared and assessed so as to produce an evaluation of each manual guidance flexible pavement design
