Combined solitons in generalized coupled mode equations of a nonlinear optical Bragg grating
(2007)We discuss the existence of combined dark and antidark soliton forms or combined solitons in the generalized coupled mode equations of a nonlinear optical Bragg grating. These solitons are not allowed in the conventional ... -
Communication Climate Forecast to Farmers Though Climate Field School : Indonesian Experience
(2010)Agriculture activities are very depending on climate condition. The failure of crops to produce good yield is very often due to bad climate. Capability of farmers to use climate forecast to anticipate the events is very ... -
Comparison of statistical models for determination of rice field phosphorus critical level
(2013)The method used in the determination of rice field phosphorus nutrient availability classes is a graphical method of Cate and Nelson (1965) and a modified analysis of variance model (Nelson and Anderson, 1977). On the other ... -
Complete Genome Sequence of the Facultative Anaerobic Magnetotactic Bacterium Magnetospirillum sp. strain AMB-1
(2005)Magnetospirillum sp. strain AMB-1 is a Gram-negative a-proteobacterium that synthesizes nano-sized magnetites, referred to as magnetosomes, aligned intracellularly in a chain. The potential of this nano-sized material is ... -

Connectivity Problem of Wildlife Conservation in Sumatra: a Graph Theory Application
(2014)In this paper, the problem of connectivity of patchy conservation sites was approached by the use of graph theory. Determination of the so-called core sites was subsequently conducted by establishing the cover areas ... -
Consistency Of A Kernel-Type Estimator Of The Intencity Of The Cyclic Poisson Process With The Linear Trend
(2009)A consistent kernel-type nonparametric estimator of the intensity function of a cyclic Poisson process in the presence of linear trend is constructed and investigated. It is assumed that only a single realization of \he ... -
Construction of family of hash functions based on ideal lattice
(2015)Cryptographic hash function is a function h : D -> R with | D | >> | R | which has the security properties: one-way (computationally not feasible to calculate x e D from known y e R so that y = h(x)) and collision resistant ... -
Correlations Between Degree of Petal Fusion, Leaf Size and Fruit Size: A Case in Syzygium (Myrtaceae)
(2009)Syzygium is one of large genera of the flowering plants. In order 10 simplify the identificalion, a classification is required, e.g. based on degree of pelal fUSion, leaf size and fruit size. Due 10 variations of vegetative ... -
CRUISE sebagai metode berstruktur pohon (Tree-Structured) pada data non-biner
