Unmanned Airborne Magnetic and VLF Investigations: Effective Geophysical Methodology for the Near Future

Airborne geophysical investigations are now recognized as a powerful tool for geological-geophysical mapping, mineral prospecting, environmental assessments, ecological monitoring, etc. Currently, however, there are two main drawbacks to effective application of these investigations: (a) the difficulty of conducting geophysical surveys at low altitudes, (b) heightened danger for the aircraft crew, especially in regions with a rugged topography. Unmanned or so-called Remote Operated Vehicles (ROV) surveys are not bound by these limitations. The new unmanned generation of small and maneuvering vehicles can fly at levels of a few (even one) meters above the Earth’s surface, and thus follow the relief, while simultaneously making geophysical measurements. In addition, ROV geophysical investigations have extremely low exploitation costs. Finally, measurements of geophysical fields at different observation levels can provide new, unique geological-geophysical information. This chapter discusses future geophysical integration into ROV of measurements of magnetic and VLF electromagnetic fields. The use of GPS with improved wide-band Kalman filtering will be able to provide exact geodetic coordinates. A novel interpreting system for complex environments is presented that includes non-conventional methods for localizing targets in noisy backgrounds, filtering temporary variations from magnetic and VLF fields, eliminating terrain relief influence, quantitative analysis of the observed anomalies and their integrated examination. This system can be successfully applied at various scales for analysis of geophysical data obtained by ROVs to search for useful minerals, geological mapping, the resolution of many environmental problems, and geophysical monitoring of dangerous geological phenomena.
Initial requirements for embryogenic calluses initiation in thin cell layers explants from immature female oil palm inflorescences

This study highlights procedures for embryogenic calluses induction from immature female inflorescences of oil palm using thin-cell-layers explants (TCL). In three experiments, the ability of calluses induction were examined and identified through different types of basal media, position of the TCL explants in the rachillae and concentrations of 2,4-D and types of antioxidants added into the medium. Samples of embryogenic calluses obtained were isolated and transversal and longitudinal cross sections were obtained and stained for observations in light microscopy. The results achieved suggest that immature female inflorescences of oil palm can be reverted from the floral state to the embryogenic vegetative state and are excellent alternative sources of explants for the induction of somatic embryogenesis. In general, 225 to 450 μM of 2,4-D are required to induce embryogenic callus in explants composed of immature oil palm inflorescences and the composition formed by salts and vitamins of MS medium provides superior results than Y3 medium. The activated charcoal at concentration of 3.0 g l -1 is the most indicated antioxidant for preventing the oxidation of floral oil palm explants and its presence can be considered essential for the formation of embryogenic callus. Key words: Elaeis guineensis, somatic embryogenesis, micropropagation, floral explants, morphogenesis, agroenergy.
Academic Landscape Based on Network Analysis Considering Analysis of Variation in the Years of Lucubration Publishing

Recent development in the field of Academic Landscape consists mainly in quotation network analysis. It is possible to sort tens of thousands of academic papers into clusters automatically by making full use of the various techniques that we describe in Section 2. However, it is not yet possible to automatically define the characteristics of each field identified by clustering as well as to automatically extract major papers in each field. Thus, We research the method to automatically identify major papers in each field recognized by clustering. Specifically, We examine the variance of years when a paper was quoted; then we apply the variance to the page rank algorithm to calculate the importance of a paper. We also aim to build up a hiangle map with a temporal axis based on the importance. Finally, We describe the constitution of this paper. Section 2 surveys the preceding studies of network analysis, clustering and bibliometrics that are element technologies to realize Academic Landscape. Section 3 describes the purpose of this study and proposed method. Furthermore, Section 4 refers to the result of experimental evaluation of the proposed method before the conclusion in Section 5.
Finding the Topics of Case Law: Latent Dirichlet Allocation on Supreme Court Decisions

The law produces a large amount case law, which is still mostly processed by hand. The Case Law Analytics project aims to develop a technology that assists the legal community in analyzing case law. As a part of this project, this thesis explores the possibilities of finding accurate and useful legal topics with LDA and whether or not legal experts and people with a non-legal background agree in their judgments about this. To this end I investigated possible methods suited for evaluation of the model’s results. I evaluated the topics as well as their assignment to the documents using human evaluation. I found that the topics evaluated to cohere most, are easy to label. Human subjects were also mostly able to differentiate between topics assigned to a document with high probability and topics that do not belong to this document. However less than half the topics were evaluated as coherent by the subjects and according to the subjects the main topic of a document was not found by the model for most of the documents. I also found that domain experts and non domain experts might evaluate topics differently. I argue that the usability of the results depends on the intended application and and introduce some complications specific to the legal domain, which should be taken into account as well.
The Role of Transhumance on Land Use /Cover Changes in Mountain Vermio, Northern Greece: A GIS Based Approach

Transhumant flocks graze the vegetation of medium and high elevation rangelands during late spring to autumn depending on the geographical area and climatic conditions. This study aimed to assess and interpret the impacts of transhumance decline on the land use/cover on Mountain Vermio, for the period 1985-2009. For many years, this area has received high stocking rates from transhumant livestock. However, during the last 30 years transhumance has been dramatically decreased. Land cover changes have been identified using a post classification comparison approach within a Geographical Information Systems environment. Moreover, the rate and the spatial differentiation of land use/cover were determined by means of the Dynamic Degree Index. According to the results, the acreage of grasslands and grazed open forests has decreased during the study period (3% and 83% respectively), while shrublands demonstrated an opposite trend with an increase of 25%. Furthermore, based on the Dynamic Degree Index, the greatest changes occurred in the conversion of grazed open forests and shrublands, compared to other land use/cover categories. This can be attributed to changes in sheep and goats populations grazing in the area, also related to the dispersion of flocks in local rangelands. Moreover, this article presents the results of a questionnaire survey on transhumant herders. These results, combined with the assessment of changes in the Dynamic Degree Index, reflect the difficulties that farmers face in terms of access to rangelands and their increased awareness regarding the environmental role of transhumance.

Design and Simulation of Jacquard Warp-knitted Towel Fabric

This article proposes a method for designing and simulating jacquard warp-knitted towel fabric. Artistic conception drawing was used in realising the CAD design function of jacquard warp-knitted towel fabric based on the fabric structure and knitting principle. This study applied NURBS curves and the surface principle to build a three-dimensional solid model of the terry loop. Then using microscope type measurement instruments, the terry loop forms of the fabric surface were analysed and models of different forms of terry loop on the fabric surface built. With visual C++ for development tools combined with OpenGL graphics libraries, a CAD design and simulation function of jacquard warp-knitted towel fabric were finally realized within the CAD system.
SENSOR- AND SCENE-GUIDED INTEGRATION OF TLS AND PHOTOGRAMMETRIC POINT CLOUDS FOR LANDSLIDE MONITORING

Abstract. Terrestrial and airborne 3D imaging sensors are well-suited data acquisition systems for the area-wide monitoring of landslide activity. State-of-the-art surveying techniques, such as terrestrial laser scanning (TLS) and photogrammetry based on unmanned aerial vehicle (UAV) imagery or terrestrial acquisitions have advantages and limitations associated with their individual measurement principles. In this study we present an integration approach for 3D point clouds derived from these techniques, aiming at improving the topographic representation of landslide features while enabling a more accurate assessment of landslide-induced changes. Four expert-based rules involving local morphometric features computed from eigenvectors, elevation and the agreement of the individual point clouds, are used to choose within voxels of selectable size which sensor’s data to keep. Based on the integrated point clouds, digital surface models and shaded reliefs are computed. Using an image correlation technique, displacement vectors are finally derived from the multi-temporal shaded reliefs. All results show comparable patterns of landslide movement rates and directions. However, depending on the applied integration rule, differences in spatial coverage and correlation strength emerge.
The theory of the line profile based on the absorption of X-ray diffraction and its experimental demonstration

We have studied the theory of the X-ray diffraction (XRD) absorption peak profile (Liu, K. et al., Adv X-ray Anal, 2010, 54, 17-23) in detail by further theoretical derivation and by verification of the experimental line profile of a standard sample. It was obtained that the deviation between theory and experiment is less than 9% for the standard samples, by ignoring the line profiles in the range of diffraction angle less than 60°, for which the instrumental broadening could not be ignored. And the theoretical formula between FWHM and the Bragg angle 2θ was derived which can be called as the ARF. The results show that the Caglioti's relations should be replaced by the formula derived in this work.
Face values on trust in loyalty and empowerment: A study of managers in China's public sector

The practice in relation to face values reflects the large power distance and collectivism prevalent in Chinese societies. Members of such societies emphasize saving and enhancing of face of individuals who occupy higher organizational hierarchy. Despite the large number of studies on face from diverse disciplines, there is limited empirical evidence on how face values influence managerial behavior in manager-subordinate relationships in China’s civil services. The current study examines the extent to which face values of Chinese managers moderate the relationship between trust in subordinate and their willingness to share information with subordinates and encourage their initiatives in China’s civil service. The findings indicate that managers’ values, which emphasize superior face-saving and face-enhancing, moderate the relationship between managers’ empowerment behaviors and their trust in subordinate’s loyalty.
Application of in vitro conservation in Vetiveria zizanioides Nash.

The shoot tip of Vetiveria zizanioides Nash var. Songkla 3 was investigated to conserve b y slowly growth conditions. After 12 months of preser vation shoot forming percentage, number of shoot, shoot length and genetic fidelity were evaluated. Shoot tips were excised and cultured on various strengths of basal Murashig e and Skoog (MS) medium supplemented with paclobutrazol (PBZ). The cultures w re placed under light condition at 14 h photoperiod, 27±1 C for 12 months. Results revealed that reducing str eng h of MS to one-forth (1/4) of original concentration supplemen ted with 3 mg/l PBZ gave the highest percentage of shoot formation and number of shoot a t 75% and 3.76 shoots per explant, respectively. The shoot length was 2-6 mm after 12 months. Random amplified polymorphic DNAs (RAPDs) marker revealed that there was no variation of DNA profiles between non-conserved and conserved plants and amon g conserved plants. These results showed that in vitro conservation by reducing strength of culture mediu m with PBZ was a practical method for the medium-term storage of vet iver grass.
3D Modeling with a Moving Tilting Laser Sensor for Indoor Environments

Abstract Many works are devoted to 3D modeling of indoor environments from mobile sensors. This function has been performed using multiple robotic platforms, equipped with different types of 3D sensors; many theoretical approaches have been proposed to refine these models, either based on SLAM algorithms when considering only sparse features, or based of ICP-based methods when a dense model is made from the registration of raw 3D data. This paper presents an approach to build a 3D surfacic model based on planar surfaces, using a tilting LRF (Laser Range Finder) mounted on the PR2 mobile robot, by the fusion of ribbons (sequence of aligned surfels) extracted from the successive scan lines. These lines are acquired on the fly from the LRF, avoiding a stop and go strategy. The ribbons are aggregated using the robot positions given by a 2D SLAM process executed independantly and simultaneously; all required information are memorized so that the surfacic model can be corrected when the SLAM process corrects the robot trajectory after a loop closure.
ROLE OF ENTREPRENEURIAL MINDSET IN SUCCESS OF ENTERPRISES OPERATED BY ENTREPRENEURSHIP UNIVERSITY GRADUATES IN KENYA

An adaptable entrepreneurial mindset is important in an entrepreneurial context because contemporary business environments are characterized by rapid, substantial, and discontinuous change (Hitt, 2000). Entrepreneurial mindset is an intervention to nascent entrepreneurs who have a deficient of entrepreneurial knowledge (experience & knowledge) which leads to venture success (Hayward, Shepherd, & Griffin, 2006). However, in Kenya, nascent entrepreneurs such as entrepreneurship university graduates lack a mindset geared towards venture growth and development, prior knowledge plus experience in entrepreneurship and the consequence is failure or stagnation The objectives of the study was to determine effect of the metacognitive resources, and influence of metacognitive monitoring and feedback mechanisms on the entrepreneurial mindset of university entrepreneurship graduates. Descriptive survey method was used to collect qualitative and quantitative data. The target population was entrepreneurship university graduates in two public (JKUAT, Moi) and two private (Strathmore, USIU) universities in Kenya. Purposive sampling and snowball were used as sampling techniques. A self-administered validated semi-structured questionnaire was used in collecting data. Descriptive and inferential statistics were used to analyze the data. Objective one determined the effect of metacognitive resources on entrepreneurial mindset. It had the best (r=0.615) correlation with entrepreneurial mindset with a factor loading 0.890. This implies that knowledge and experience of a business is the most important ingredient to success of an enterprise. Objective two examined the influence of metacognitive monitoring and feedback mechanisms on entrepreneurial mindset. Metacognitive feedback was the second best with a weak positive correlation (r=0.150) to entrepreneurial mindset. This implies that the ability to monitor the growth of an enterprise is of paramount importance to an entrepreneurship graduate. The conclusion was that the most important predictor of success in enterprises with metacognitive feedback as the second best predictor. The study recommended that entrepreneurial mindset should be made compulsory subject in the curriculum of tertiary institutions. Key Words : Entrepreneurial Mindset, University Graduates
A new parameterized architectural design for SENSE reconstruction

Reconfigurable hardware based architectures that could provide good quality image reconstruction for parallel Magnetic Resonance Imaging (MRI) within very less computation time are in high demand. Hardware platforms for specific reconstruction algorithms dramatically increase the power efficiency and decrease the execution time. This research proposes a new parameterized architecture design for Sensitivity Encoding (SENSE) reconstruction. This architecture is also synthesized for Field Programmable Gate Array (FPGA). Complex multiplier, divider and complex matrix multiplier modules are designed to implement the algorithm. Furthermore, the variable data bus widths are used in the data path of the architecture, which leads to reduce the hardware cost and silicon area. Experimental results and comparisons prove the efficiency of the architecture. Moreover, in terms of computation time, the result shows that the proposed technique is 1000 times faster than the conventional MATLAB reconstruction, while maintaining the quality of the reconstructed image. The results indicate that this architectural design can prove to be a significant tool for SENSE reconstruction in MRI scanners.
Magnetic Study of the Heated and Unheated Sedimentary Fillings of Sebkha Mhabeul, Southeast Tunisia: A Geophysical Method for Paleoclimatic Investigation and Tephrochronological Dating

This paper is meant to investigate the climatic and volcanic signals within the sedimentary filling of sebkha Mhabeul through a thermomagnetic study of a 37 cm length core. Values of the magnetic susceptibility at ambient temperature show that the core encompasses four climatic stages: the Warming Present (WP), the Little Ice Age (Late LIA), Early Little Ice Age (ELIA), and the Medieval Climate Anomalies (MCA). Added to the subcycles, the spectral analysis shows the individualization of an 888 yr cycle probably related to solar activity. The heating at 250°C is good-for-nothing since it was useful neither for climatic investigation nor for tephras layers detection. Heating at 700°C generated the complete loss of the climatic signal. On the other hand, it allowed the detection of the previously identified tephras layers. Further, it highlighted the presence of other tephras layers. The extraction by the bromoform confirms the presence of these tephras. The use of the same methodology may allow the detection of tephras layers within other sebkhas.
Hydrogen Bonding and Intermolecular S…O Interaction in the Absorption Processes of SO 2

In previous work, isothermal gas-liquid equilibrium (GLE) data show that diethylene glycol (DEG) (1) + water (2) solutions (DEGWs) can be used as the promising medium for the absorption processes of SO2, which showed that w1 = 0.60 DEGW (mass fraction) presents the extreme minimum solubility of 110 mg·L -1
Influence of Mathematical Representation and Mathematics Self-Efficacy on the Learning Effectiveness of Fifth Graders in Pattern Reasoning

The purpose of this study was to investigate the influence of mathematics self-efficacy and diverse mathematical representations in learning materials on the performance and learning attitude of elementary school learners with regard to pattern reasoning. The research samples comprised 121 fifth graders from an elementary school in Central Taiwan. We adopted a two-factor quasi-experimental design with mathematical representation and mathematics self-efficacy as the independent variables. Digital learning materials were graphical or numerical and the learners designated as having high or low mathematics self-efficacy. The dependent variables included pattern reasoning performance and attitudes towards learning mathematics. The former was divided into number sequence reasoning and graphic sequence reasoning, whereas the latter included learning enjoyment, motivation, and anxiety. The research findings indicate that (1) using graphical learning materials enhances performance in pattern reasoning; (2) using digital learning materials in teaching can improve attitudes towards learning mathematics; (3) learners with high mathematics self-efficacy display more positive attitudes towards learning mathematics.
Distribution and Status of Mule Deer (Odocoileus hemionus) in Oklahoma: an Analysis of Harvest Data

Distribution records of mule deer (Odocoileus hemionus) in the southern Great Plains are well documented with the exception of Oklahoma, where verified records are few. To estimate the distribution and status of mule deer in Oklahoma, we surveyed harvest records (2001-2008) from 93 Oklahoma Department of Wildlife Conservation harvest regions in western Oklahoma. Mule deer were reported from 37 harvest regions. Annual harvests varied among harvest regions. Consistent annual harvests for each harvest region indicated stable populations, potentially due in part to steady immigration from permanent populations in the panhandle regions of Texas and Oklahoma and western Kansas. Abundance of mule deer reports followed a northwest to southeast gradient, highest in the northwest. Variation in mule deer abundance, based on harvests, was associated with the distribution of optimal, suitable, and marginal habitats. Our results verify mule deer in western Oklahoma and give an approximated range boundary and help to identify specific regions where future research efforts might add to our knowledge of the species. © 2010 Oklahoma Academy of Science.
