Vertical Stabilization of a Rocket on a Movable Platform

Suppose we have a rocket on a movable platform which may be slightly misaligned from the vertical position and we want to correct this misalignment just before the rocket is launched by applying a control force to the platform. In this chapter, we construct a simple model which can be used to determine such a control force in the case where the misalignment occurs in the direction parallel to the wheels of the platform. For our initial model, following Ogata [1], we will model the rocket as an inverted pendulum with its mass concentrated at the tip. We will assume that the platform rolls without resistance along the ground and that the mass and length of the rocket and the mass of the platform are known with a relative error less than . 0001. Certain constraints will be imposed on the control force and the motion of the rocket which we will refer to as design criteria. We assume the following launch sequence. The rocket is initially at rest and constrained by a mechanical arm to be within 1 degree of vertical. Ten seconds before lift-off the mechanical arm is removed and a control force is applied to the platform to bring the rocket into a vertical position within 4 seconds. During the time remaining before lift-off, subsystem go/no-go signals are analyzed and a launch go/no-go decision is made. Beginning with our idealized physical model, we derive a mathematical, state-space model consisting of a system of 4 nonlinear ordinary differential equations. The state variables are the angle of the rocket from vertical, the position of the platform, and their time derivatives. We linearize these equations for small angular deviations of the rocket from vertical arriving at a linear system of ordinary differential equations. We use state feedback to control the system in which case the control force is represented as a linear combination of the state variables. Now standard linear control theory can be applied. The response of the linear system is governed by the eigenvalues of the system matrix, and the eigenvalues of the system matrix determine the control force. We use the following design procedure to find a suitable control force. Choose a set of eigenvalues for the linear system. Compute the corresponding control force. Simulate the nonlinear system using the computed control and evaluate the response. Repeat until all design criteria are satisfied.

Kinematics Analysis of Two Parallel Locomotion Mechanisms

Abstract : This dissertation presents the kinematics study on two cases of parallel locomotion mechanisms. A parallel locomotion mechanism can be defined as "a mechanism with parallel configuration and discrete contact with respect to the ground which renders a platform the ability to move". The first case is a tripedal robot and the second case is an actuated spoke wheel robot. The kinematics study on these two mobile robots mainly includes mobility, inverse and forward kinematics, instantaneous kinematics singularity and so on. The tripedal robot STriDER (Self-excited Tripedal Dynamic Experimental Robot) is expected to walk utilizing its built-in passive dynamics, but in its triple stance phase the kinematic configuration of the robot behaves like an in-parallel manipulator. The locomotion of this novel walking robot and its unique tripedal gait are discussed followed by the definitions of its coordinate frames. Geometric methods are adopted for the forward and inverse displacement analysis in its triple stance phase. Simulations are presented to validate both the inverse and the forward displacement solutions. The instantaneous kinematics and singularity analysis are developed respectively. Based on the screw theory, the Jacobian matrices are assembled. Using Grassmann Line Geometry, each row of the Jacobian matrices is interpreted as a line in 3D space and the analytical conditions of the linear dependency cases are identified, which corresponds to the forward singular configurations of the robot. The actuated spoke wheel robot IMPASS (Intelligent Mobility Platform with Active Spoke System) is investigated as the second case. It is revealed that this robot has multiple modes of locomotion on the ground and it is able to change its topology by changing the contact scheme of its spokes with the ground.
Serum apelin levels and cardiovascular diseases

Apelin is a G protein-linked receptor endogenous ligand, synthesized as a 77-amino acid pre-propeptide. Increased expression of apelin is present in many cardiovascular (CV) tissues, including cardiomyocytes. It is a peripheral vasodilator and one of the most potent stimulants of ventricular contraction. Apelin may be a valuable therapeutic for both blood pressure regulation and myocardial performance. More information is needed for the CV pathophysiology of apelin. We will discuss the importance of apelin level in CV diseases in this review.
Extraction of surface defects using morphological pyramid and watershed: example of ferrite cores

The paper describes a vision system for detection and extraction of the masks of defects on the surface of ferrite cores. Separate approaches are used for small and large defects. The system for small defects uses a morphological defect detector and a morphological pyramid for detecting positions of defects. Optimization of the performance of the morphological pyramid is carried out by means of the genetic algorithm. Information obtained from the pyramid on the position and extent of defects gives a very coarse approximation of the shape of defects. Using this information, the exact shape of the small defects is then obtained by means of two consecutive morphological reconstructions. The system for large defects uses the information obtained while attempting to detect small defects. In addition to this, however, it uses the watershed segmentation for extracting the exact shape of large defects. In particular, the output from the watershed segmentation is processed by the region classifier which decides upon which regions from the segmentation should be included into a defect and into a defect free area. The paper also discusses problems related to extraction of cracks of ferrite cores. A fair number of included examples confirm that the described vision system correctly identifies and extracts a large range of defects of ferrite cores.

The utility of knowledge mapping as an approach to improving corporate and project performance: a case study of a large South Korean consulting firm

Knowledge, and its appropriate management, has been increasingly recognised as a critical source of sustainable competitive advantage for companies. Within this context, many companies are developing their strategies and capabilities to effectively create, share and exploit knowledge. This issue has been seen to be particularly important in project-based industries, such as the construction industry. However, in spite of the espoused value of knowledge management approaches they often deliver benefits far below expectations. Research and practice has identified a number of problems and barriers which have depleted the actual benefits of knowledge management in projects and companies. A generic finding is that the major problem is the lack of effective integration of key knowledge management components. Knowledge maps have been promoted as a key solution to bring about this required integrated approach. The knowledge mapping approach has taken root in other sectors (particularly education and manufacturing), but is still at an embryonic state in construction. The starting point for this research is to investigate the potential utility of knowledge mapping as an approach to improving corporate and project performance. First, a concept model for appropriate knowledge mapping within construction project organisations was articulated through a relevant literature review. The model is made up of four key variables: interaction environment, construction actors, construction processes and knowledge transfer technologies. The concept model was tested through a single-holistic case study within a large construction and property consulting practice in South Korea. Data collection was through semistructured interviews and company document review. The primary data was analysed using content analysis and cognitive mapping. The research findings broadly confirmed that knowledge mapping is an effective approach in integrating project resources and technologies for successful knowledge management within the case study firm. The key characteristics of the concept model in practice are identified and illustrated. A contingency approach to knowledge mapping is proposed with appropriate approaches dependent upon the scope of the construction processes and the scope of the construction actors.

Cancer-driven IgG promotes the development of castration-resistant Prostate Cancer though the SOX2-CIgG pathway

Background: Although Androgen deprivation therapy (ADT) is the initial treatment strategy for prostate cancer, recurrent castration-resistant prostate cancer (CRPC) eventually ensues. In this study, cancer-derived immunoglobulin G(CIgG) was found to be induced after ADT, identifying CIgG as a potential CRPC driver gene.Methods: The expression of CIgG and its clinical significance in prostate cancer tissue was analyzed by TCGA database and immunohistochemistry. Subsequently, the sequence features of prostate cell line (LNcap, DU145, PC3) VHDJH rearrangements were analyzed via comparison with the best matching functional germline IgVH, IgDH and IgJH genes. We also assessed the effect of CIgG on the migratory, invasive and proliferative abilities of prostate cancer cells in vitro and vivo. Cells with high CIgG expression (CIgGhigh) and low CIgG expression (CIgG-/low) from the PC3 cell line were sorted by FACS using a CIgG monoclonal antibody named RP215, then, suspended microsphere, colony formation and drug-resistant assays were performed. A NOD/SCID mouse tumor xenograft model was developed for the study of the tumorigenic effects of the different cell populations. The AR-SOX2-CIgG signaling pathway was validated by immunohistochemistry, immunofluorescence, qRT-PCR, Western blot, luciferase and ChIP assays and bioinformatics analyses. Finally, we investigated the effect of RP215 inhibition on the progression of prostate cancer in vivo using a Babl/c nude mouse xenograft model.Results: We demonstrated that CIgG was induced by androgen deprivation therapy (ADT) and upregulated by SOX2 [SRY (sex determining region Y)-box 2] in prostate cancer, which may promote the development of CRPC. In addition, our findings underscore a novel role of CIgG signaling in the maintenance of stemness and the progression of cancer through MARK/ERK and AKT in prostate cancer.Conclusion: Our data suggests that CIgG could be a driver of CRPC development, and that targeting the SOX2-CIgG axis may therefore inhibit CRPC development after ADT.

Guidelines for Conducting Extended Cost-benefit Analysis of Dam Projects in Thailand

Dam construction has long provided valuable economic benefits to Thailand in distributing low-priced electricity and supporting low-income farmers by providing them with free-flowing irrigation water; this promotes domestic consumption and investment. Even though many benefits are expected from dam construction, a dam project needs to be carefully evaluated using cost-benefit analysis (CBA) before approval. Decision-makers have to review the negative effects of the construction and operation of a dam. These effects are sometimes difficult to measure in monetary terms.
High linearity 1.5-2.5 GHz RF-MEMS and varactor diodes based tunable filters for wireless applications

The dissertation presents tunable banpass filters in the 1.5-2.5 GHz frequency range targeted for wireless applications. The tunable filters are designed for size miniaturization, good linearity and constant absolute bandwidth characteristics while maintaining low insertion loss. The improved linearity has been demonstrated using back-to-back varactor diodes and using RF MEMS devices. The constant absolute bandwidth characteristics was achieved using a novel corrugatedcoupled lines approach and also using a localized capacitive compensation concept. In the improved linearity varactor diode design, two miniaturized tunable filters with two zeros were developed at 1.4-2.0 GHz on. The filters were built using single and back-to-back varactor diodes and compared for linearity characteristics. The single diode filter has a 1 -dB bandwidth of 5 ± 0.5 % and an insertion loss of 2.5- 1.8 dB. The back-to-back diode filter has a 1-dB bandwidth of 4.9 ± 0.5 % and an insertion loss of 2.9-1.25 dB (resonator Q of 56-125). A detailed Volterra series analysis is done on the back-to-back diode including the effect of the bias network and diode mismatches. The measured IIP₃ for the back-to-back diode tunable filter is 22-41 dBm depending on the bias voltage and is 13-15 dB better than the single diode design. The power handling capabilities of both designs is explored using large signal S₂₁ measurements. To our knowledge, these planar tunable filters represent state-of-the-art insertion loss and linearity characteristics performance with varactor diodes as the tuning elements. In the corrugated coupled- lines design, miniaturized fixed and tunable microstrip bandpass filters were developed t 1.4-1.9 GHz. The novel approach uses microstrip corrugated coupled-lines concept to synthesize a coupling coefficient which maintains a nearly constant absolute bandwidth across the tuning range. In addition, a miniaturized 2-pole varactor tuned filter is demonstrated with a frequency coverage of 1.44- 1.89 GHz and an insertion loss > 33 dBm. The filters also showed no distortion when tested under wideband CDMA waveforms up to 24.8 dBm. The designs can be scaled to higher dielectric-constant substrates to result in even smaller filters.
Ontology-Based Learning Framework for Activity Assistance in an Adaptive Smart Home

Activity and behaviour modelling are significant for activity recognition and personalized assistance, respectively, in smart home based assisted living. Ontology-based activity and behaviour modelling is able to leverage domain knowledge and heuristics to create Activities of Daily Living (ADL) and behaviour models with rich semantics. However, they suffer from incompleteness, inflexibility, and lack of adaptation. In this article, we propose a novel approach for learning and evolving activity and behaviour models. The approach uses predefined “seed” ADL ontologies to identify activities from sensor activation streams. Similarly, we provide predefined, but initially unpopulated behaviour ontologies to aid behaviour recognition. First, we develop algorithms that analyze logs of activity data to discover new activities as well as the conditions for evolving the seed ADL ontologies. Consequently, we provide an algorithm for learning and evolving behaviours (or life habits) from these logs. We illustrate our approach through scenarios. The first scenario shows how ADL models can be evolved to accommodate new ADL activities and peculiarities of individual smart home’s inhabitants. The second scenario describes how, subsequent to ADL learning and evolution, behaviours can be learned and evolved.
In vitroslow growth storage of date palm Phoinex dactyliferacv. Gondelah using somatic embryo and the shoot cultures

In vitro germplasm conservation is one of the main axes in the date palm (Phoinex dactylifera) micropropagation protocol. In the present study, a set of slow growth storage treatments planned by using the manipulation of the MS salts strength, besides adding the abscisic acid (ABA) growth retardant, to the storage culture media of tow regenerative in vitro germplasm materials, i.e., the somatic embryo and the shoot cultures, of the date palm Gondelah cultivar. The investigated study conducted by observing the growth ability under the conservation conditions, the survival and the recovery growth, after the conservation period for 18 months at 15 ̊C of the minimal growth conditions, the results revealed that half-MS strength medium, supplemented with ABA growth retardant at 8 mg/l, was the best to sustain the slow growth storage and the recovery of the date palm somatic embryo clusters explants. On the other hand, the full-MS medium supplemented with ABA growth retardant at 8 mg/l was most suitable for the in vitro preservation and the recovery of the shoot clusters of the date palm, Gondelah cultivar. Where, all recovered explants could regenerate as full intact plantlets, and successfully transferred to the acclimatization stage, to be available for the commercial or research purposes.

Study of Interaction Between Bovine Serum Albumin and Dolutegravir Intermediate: Fluorescence and Molecular Docking Analysis

Novel (4R,12aS)-7-methoxy-4-methyl-6,8-dioxo-3,4,6,8,12,12a-hexahydro-2H-pyrido-[1',2':-4,5]-pyrazino[2,1-b][1,3]oxazine-9-carboxylic acid (L) was synthesized and characterised. The interaction between bovine serum albumin (BSA) with L was scrutinized by steady-state fluorescence spectroscopy, fluorescence anisotropy, fluorescence lifetime, and molecular docking methods. The fluorescence titration experiments of BSA resulted in fluorescence quenching with the incremental addition of L. The conformational binding of L to BSA has been investigated by molecular docking analysis. The molecular probe's best conformation showed the affinity as free binding energy release of -7.93 Kcal/mol. The docking analysis confirms that ligand binds in the near vicinity of TRP-213 in the binding pocket of subdomain IIA.
Novel Micromotion-Balancing Drilling Technology to Increase Proximal Cortical Strain

Background: We aimed to design a micromotion-balancing drilling system on the basis of the existing locking plate to maintain the balance of the micromotion of the cortex on both sides of a fracture region. We tested the system by subjecting it to a few biomechanical tests.Methods: According to the shape of screw holes on the cortex, the fixed fracture models were divided into a control group (standard screw hole group X126, 6 cases) and an experimental group (elliptical screw hole group N, 36 cases). The experimental group was further divided into 6 subgroups with 6 cases in each (N126, N136, N1256, N1356, N12356, N123456) on the basis of the number and distribution of the screws on the proximal fracture segment. The control, N126, and N136 groups were subjected to 500-N axial load, and other groups were subjected to 1000-N axial load. The displacements of the kinetic head, distal cortex, and proximal cortex were measured. The integral structural stiffness of the model and the proximal cortical strain were calculated. The data of each group were analyzed by paired t-tests.Results: When the distal cortical strains were 2%, 5%, and 10%, the proximal cortical strains in group N126 were 0.96%, 2.35% and 4.62%, respectively, which were significantly higher than those in the control group (X126) (p<0.05). When the distal cortical strains were 2%, 5% and 10%, the proximal cortical strain in group N126 was significantly higher than that in group N136 (p<0.05). However, there was no significant difference between the proximal cortical strains in the two groups with 4 screws (p>0.05). The proximal cortical strain in the 3-screw groups was significantly higher than that in the 4-screw groups (p<0.05), and there was no significant difference in the proximal cortical strain in the 4-, 5-, and 6-screw groups (p>0.05). Conclusions: The new drill and the matching sleeves enabled a conventional locking compression plate to be transformed into an internal fixation system and improved the balanced motion of the distal and proximal cortices. Thus, the strain on a fracture site can be controlled by adjusting the drill diameter and sleeve eccentricity.
