On the embeddability of certain infinitely divisible probability measures on Lie groups
We describe certain sufficient conditions for an infinitely divisible
probability measure on a class of connected Lie groups to be embeddable in a
continuous one-parameter convolution semigroup of probability measures.
(Theorem 1.3). This enables us in particular to conclude the embeddability of
all infinitely divisible probability measures on certain Lie groups, including
the so called Walnut group (Corollary 1.5). The embeddability is concluded also
under certain other conditions (Corollary 1.4 and Theorem 1.6).Comment: 24 page

Does New Zealand visitors follow the Joseph Effect? Some empirical evidence
The report departs from conventional time series analysis and investigates the existence of long memory (LRD) in the stream of daily visitors, arriving from various sources to New Zealand from 1997 to 2010, using selected estimators of the Hurst-exponent. The daily arrivals of visitors are treated as a stream of "digital signals" with the inherent noise. After minimizing the noise (i.e. the presence of short-term trends, periodicities, and cycles) we found the existence of significant long memory embedded in our data of daily visitors from all sources and in the aggregate. Strong evidence of embedded “long memory” implies that Joseph Effect – that good times beget good times and bad times beget bad – whose existence in the underlying process may have interesting implications for tourism policy makers. Our findings suggest evidence of such long term memory in tourist arrival data. Further, unless this long memory effect is taken into consideration, any traditional statistical analysis based on Gaussian and Poisson assumptions may be overly biased
EFFECTIVENESS OF USING VIDEO IN THE LEARNING OF COMPUTER HARDWARE ASSEMBLING CLASS XII INDUSTRIAL ELECTRONICS IN SMK NEGERI 2 WONOSARI
This study aims to determine the effectiveness of video in the learning materials and computer hardware assembling to know the difference student learning outcomes before and after using video in class XII Industrial Electronics SMKN 2 Wonosari.
This research was conducted in November 2010 until December 2010. Type research is kind of population research because the sample size research take the entire population of the entire class XII students of Industrial Electronics, this population is 35 students. Research’s method is Pre-Experimental Designs and using One-Group Pretest-Posttest Design. This method aims to determine the effect of a treatment in the learning process. The media used is a CD video tutorial "Merakit Komputer Untuk Orang Awam." Data collection techniques used in this research using a pretest and posttest. Validation of research instruments is through expert opinions (judgments) and then tested through a pretest on students majoring in Industrial Electronics XII SMK N 2 Wonosari. Data analysis techniques used to analyze the research data is to be tested in SPSS 17 for Windows.
Based on a research known to increase learning outcomes after a given treatment using video CD Tutorial is from 63.97 (mean pretest) to 76.37 (mean posttest). Results mastery learning after using video media tutorial CD reaches 71.42% which means that these results exceeded the minimum limit of 65% so that concluded video media Tutorial CD " Merakit Komputer Untuk Orang Awam " not yet effective in learning to use the lessons of computer hardware assembling class XII Industrial Electronics SMK Negeri 2 Wonosari.
