Abstract
Dengue fever is a vector-borne disease with Aedes aegypti as the main vector. Vector controls currently depended on insecticide. Considering the negative effect of insecticide, Sterile Insect Technique (SIT) was developed. This study was conducted to evaluate the effect of gamma-ray irradiation on the productivity of male Ae. aegypti. Male pupae age less than 15 hours were irradiated with 60 Gy and 70 Gy gamma-ray. When the pupae became adult, the sterile males mated with the same age females Aedes aegypti. Observation on fecundity, hatchability, and age was carried out until the second generation. Gamma-ray irradiation with the dose of 60 Gy and 70 Gy showed different effects on fecundity, egg hatchability, the emergence of the adult, and age of Aedes aegypti compared to control.

The results of testing thin-walled welded joints (high-temperature assemblies of epitaxial installations) obtained by electron-beam welding using the eddy current method are presented. The tightness of those parts and assemblies is controlled by vacuum and compression leak detection methods, based on increasing the test gas concentration on the one side of the test surface and sampling it for mass spectrometric analysis on the other side. Helium mass spectrometric leak detectors are now widely used in aerospace, electronics and chemical industries, as well as in the instrument making industry and scientific research. The eddy current method provides a high scanning speed and allows timely detection of the defects and prevention of the risk of accidental wear of thin-walled elements and parts of aerospace and petrochemical equipment. The goal of this work is to optimize the control of welded joints of thin (0.2 and 0.5 mm) tantalum screen using a VEKTOR-60D detector and eddy current method. The device provides the use of overhead or flow eddy current differential, tangential and absolute transducers operating at a frequency from 10 Hz to 20 MHz, as well as various dynamic transducers. The device is designed to control metal products, carbon plastics and composites for the presence of defects such as surface and subsurface cracks, discontinuities and homogeneity of materials. VEKTOR-60D allows one to get a simultaneous signal display on the flaw detector screen both in the amplitude-time and complex planes. The used sensors (PVDT-1000-2, PVD-200-2,3, and VP160A45) provided detection of the defects across the entire width of the weld and heat-affected zone in one pass along the welded joint. The defect of the welded joint of the tantalum screen was revealed as incomplete penetration (nonpenetration in the weld root) in accordance with the classification of GOST R ISO 6520-1–2012. The results proved that a VEKTOR-60D eddy current detector can be successfully used in monitoring defects in thin-walled welded joints.

AbstractThe most widely used of control chart in multivariate control processing is control chart T2 Hotelling. There are 2 kinds of control chart T2 Hotelling, namely T2 Hotelling for group observation and T2 Hotelling for individual observation. In this paper, discuss the control chart T2 Hotelling for individual observation. This control chart is used for monitoring of mean vector and sample of covariance matrix. Mean vector and sample of covariance matrix are very sensitive with respect to extreme point (outliers). Therefore, it is needed an estimator of mean vector and has a stocky population covariance matrix to the outliers data. One method that can be used to detect data that contains outliers is Minimum Covariance Determinant (MCD). From the calculation results, obtained that control chart T2 Hotelling by using Fast-MCD algorithm is more sensitive to detect outliers data than T2 Hotelling classically.Keyword: T2 Hotelling, Minimum Covariance Determinant (MCD), robust, outlier AbstrakBagan kendali yang paling banyak digunakan dalam pengendalian proses secara multivariat adalah bagan kendali T2 Hotelling.

Full textAbstract:
In this work, the laser control of molecules was investigated theoretically. In doing so, emphasis was layed on entering vectorial properties and in particular the orientation in the laboratory frame. Therefore, the rotational degree of freedom had to be included in the quantum mechanical description. The coupled vibrational and rotational dynamics was examined, which is usually not done in coherent control theory. Local control theory was applied, where the field is determined from the dynamics of a system, which reacts with an instantaneous response to the perturbation and, in turn, determines the field again. Thus, the field is entangled with the quantum mechanical motion and the presented examples document, that this leads to an intuitive interpretation of the fields in terms of the underlying molecular dynamics. The limiting case of a classical treatment was shown to give similar results and hence, eases to understand the complicated structure of the control fields. In a different approach, the phase- and amplitude shaping of laser fields was systematically studied in the context of controlling population transfer in moleculesDas Ziel dieser Arbeit war die theoretische Analyse der Laserkontrolle von Molekülen. Ein Schwerpunkt lag dabei auf vektoriellen Eigenschaften und im Besonderen auf der Orientierung eines Moleküls im Laboratorium. Hierfür wurde der Rotationsfreiheitsgrad in die quantenmechanische Beschreibung einbezogen. Die Kopplung zwischen Vibrations- und Rotationsdynamik wurde explizit berücksichtigt, während dieser Vorgang normalerweise bei theoretischen Untersuchungen zur kohärenten Kontrolle vernachlässigt wird. Als Kontrollschema wurde die lokale Kontrolltheorie (LCT) verwendet, in der das Feld aus der Dynamik eines Systems bestimmt wird, welche sofort auf diese äußere Störung antwortet und damit wiederum das Feld bestimmt. Somit ist das Feld mit der quantenmechanischen Bewegung verknüpft. Die vorgestellten Beispiele dokumentieren, dass dies zu einer intuitiven Interpretation der Felder bzgl. der zu Grunde liegenden molekularen Dynamik führt. In der vereinfachten, klassischen Darstellung der Probleme findet man vergleichbare Resultate. Die klassische Sichtweise ermöglicht ein anschauliches Verständnis der komplizierten Strukturen der Kontrollfelder. Zusätzlich wurde mit einem anderen Ansatz die Phasen- und Amplitudenformung von Laserfeldern systematisch untersucht, wobei der Populationstransfer in Molekülen kontrolliert werden sollte
