  • In many moving object detection problems of an aerial video, accurate and robust stabilization is of critical importance. In this paper, a novel accurate image alignment algorithm for aerial electronic image stabilization (EIS) is described. The feature points are first selected using optimal derivative filters based Harris detector, which can improve differentiation accuracy and obtain the precise coordinates of feature points. Then we choose the Delaunay Triangulation edges to find the matching pairs between feature points in overlapping images. The most "useful" matching points that belong to the background are used to find the global transformation parameters using the projective invariant. Finally, intentional motion of the camera is accumulated for correction by Sage-Husa adaptive filtering. Experiment results illustrate that the proposed algorithm is applied to the aerial captured video sequences with various dynamic scenes for performance demonstrations.

  • Carnosol is a phenolic diterpene phytochemical found in rosemary and sage with reported anti-microbial, anti-oxidant, anti-inflammatory, and anti-carcinogenic activities. This study aimed to investigate the effect of carnosol on the lineage commitment of mouse bone marrow-derived mesenchymal stem cells (mBMSCs) into osteoblasts and adipocytes. Interestingly, carnosol stimulated the early commitment of mBMSCs into osteoblasts in dose-dependent manner as demonstrated by increased levels of alkaline phosphatase activity and Alizarin red staining for matrix mineralization. On the other hand, carnosol significantly suppressed adipogenesis of mBMSCs and downregulated both early and late markers of adipogenesis. Carnosol showed to induce osteogenesis in a mechanism mediated by activating BMP signaling pathway and subsequently upregulating the expression of BMPs downstream osteogenic target genes. In this context, treatment of mBMSCs with LDN-193189, BMPR1 selective inhibitor showed to abolish the stimulatory effect of carnosol on BMP2-induced osteogenesis. In conclusion, our data identified carnosol as a novel osteoanabolic phytochemical that can promote the differentiation of mBMSCs into osteoblasts versus adipocytes by activating BMP-signaling.

  • This study examined the growth of herb plants in response to irrigation on a green rooftop area in order to select herb plants that can be used for rooftop greening. Apple Mint (Mentha suaveolens), Lemon balm (Melissa officinalis), Spearmint (Mentha spicata), Pineapple sage (Salvia elegans), Choco Mint (Mentha ${\times}$ piperita 'Choco Mint'), Ox-eye Daisy (Chrysanthemum leucanthemum), Roman Chamomile (Anthemis nobilis) and Thyme (Thymus vulgaris) showed increased growth when irrigated. Conversely, Lavender (Lavendula angustifolia ), Peppermint (Mentha ${\times}$ piperita ), Vicks Plant (Plectranthus tomentosa), Feverfew (Tanacetum parthenium), Rosemary (Rosmarinus officinalis), Tansy (Tanacetum vulgare), Lemon Verbena (Aloysia triphylla), Heliotrope (Heliotropium arborescens), Soapwort (Saponaria officinalis) and Lady's mantle (Alchemilla vulgaris) demonstrated satisfactory growth regardless of irrigation. Peppermint, Tansy, Lemon Verbena, Soapwort, and Lady's mantle seem to be suitable for green rooftop because of their overwintering ability and drought hardiness. Pineapple sage, Apple Mint and Thyme would seem to be inappropriate for rooftop greening because they showed negative growth response to drought and failed overwintering. Although Spearmint, Lemon balm, Choco Mint, Ox-eye Daisy and Roman Chamomile had reduced growth during dry conditions, they were able to overwinter satisfactorily and can be used as rooftop plants with irrigation.

  • Whereas NIR spectroscopy has been applied in agriculture for more than 20 years, few studies refer to those plant substances occurring only in smaller amounts. Nevertheless there is a growing interest today to support efficiently activities in the production of high-quality medicinal and spice plants by this fast and non-invasive method. Therefore, it was the aim of this study to develop new NIR methods for the reliable prediction of secondary metabolites found as valuable substances in various plant species. First, sophisticated NIR methods were established to perform fast quality analyses of intact fennel, caraway and dill fruits deriving from single-plants [1]. Later on, a characterization of several leaf drugs and the corresponding fresh material has been successfully performed. In this context robust calibrations have been developed for dried peppermint, rosemary and sage leaves for the determination of their individual essential oil content and composition [2]. A specially adopted NIR method has been developed also for the analysis of carnosic acid in the leaves of numerous rosemary and sage gene bank accessions. Carnosic acid is an antioxidative substance for which several health promoting properties including cancer preservation are assumed. Also some other calibrations have been developed for non-volatile substances such as aspalathin (in unfermented rooibos leaves), catechins (in green tea) and echinacoside (in different Echinacea species) [3]. Some NIR analyses have also been successfully performed on fresh material, too. In spite of the fact that these measurements showed less accuracy in comparison to dried samples, the calibration equations are precise enough to register the individual plant ontogenesis and genetic background. Based on the information received, the farmers and breeders are able to determine the right harvest time (when the valuable components have reached their optimum profile) and to select high-quality genotypes during breeding experiments, respectively. First promising attempts have also been made to introduce mobile diode array spectrometers to collect the spectral data directly on the field or in the individual natural habitats. Since the development of reliable NIRS methods in this special field of application is very time-consuming and needs continuous maintenance of the calibration equations over a longer period, it is convenient to supply the corresponding calibration data to interested user via NIRS network. The present status of all activities, preformed in this context during the last three years, will be presented in detail.

  • The purpose of this study was to investigate how herb extracts may improve blood circulation. Twenty-six extracts from nine different herbs (marjoram, lavender, dill, rosemary, hyssop, rose, lemon balm, pineapple sage, and echinacea) were evaluated for their anti-hypertensive effects via angiotensin I converting enzyme (ACE) inhibition. Their cholesterol-lowering effects via hydroxy-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibition and their fibrinolytic activity via fibrin-plate method were also evaluated. Both water extraction of rose flowers and 70% EtOH extraction of pineapple sage leaves effectively reduced the ACE activity with inhibition rates of 133.8% and 91.2%, respectively. Similarly, both water and 70% EtOH extracts of rose flowers strongly inhibited the enzymatic activity of HMG-CoA reductase by 48.9% and 80.5%, respectively. Water and 70% EtOH extracts of rose flowers also showed relatively high fibrinolytic activity. Based on these observations, rose flower extracts can be developed as a functional tool for use in the improvement of blood circulation.

  • To develop natural antioxidant from spices and control thermal oxidation of edible soybean oil, the available antioxidative compounds of various spices were extracted with edible soybean oil. The storage stability of the oil mixed with purified sardine oil and soybean oil containing that extracts at $37^{\circ}C$ were investigated. Furthermore the antioxidative activity of petroleum ether soluble fractions(PESF) obtained from rosemary on the thermal oxidation of edible soybean oil during heating at $180^{\circ}C$ were also investigated. By mixing with refined sardine oil and soybean oil extracts of rosemary, sage of herb spices and mace of seed spices, the oxidative stabilities were remarkably increased. The thermal oxidation of edible soybean oil was also supressed by the addition of 1.0%(w/w) of PESF obtained from rosemary. Rosemary extract exhibited higher antioxidative activity on thermal oxidation of edible soybean oil than butylated hydroxytoluene.

  • Ultrasonic inspection methods are widely used for detecting flaws in materials. The signal analysis step plays a crucial part in the data interpretation process. A number of signal processing methods have been proposed to classify ultrasonic flaw signals. One of the more popular methods involves the extraction of an appropriate set of features followed by the use of a neural network for the classification of the signals in the feature spare. This paper describes an alternative approach which uses the least mean square (LMS) method and exportation maximization (EM) algorithm with the model based deconvolution which is employed for classifying nondestructive evaluation (NDE) signals from steam generator tubes in a nuclear power plant. The signals due to cracks and deposits are not significantly different. These signals must be discriminated to prevent from happening a huge disaster such as contamination of water or explosion. A model based deconvolution has been described to facilitate comparison of classification results. The method uses the space alternating generalized expectation maximiBation (SAGE) algorithm ill conjunction with the Newton-Raphson method which uses the Hessian parameter resulting in fast convergence to estimate the time of flight and the distance between the tube wall and the ultrasonic sensor. Results using these schemes for the classification of ultrasonic signals from cracks and deposits within steam generator tubes are presented and showed a reasonable performances.
