Annotation:

This article responds to Quentin Smith's, ‘The Reason the Universe Exists is that it Caused Itself to Exist’, Philosophy74 (1999), 579–586. My rejoinder makes three main points. The first is that Smith's argument for a finitely old, but causally self-explanatory, universe fails from probative overkill: if sound, it also shows that all manner of paltry event-sequences are causally self-explanatory.The second point is that the refutation of Smith's argument extends to Hume's argument for an infinitely old causally self-explanatory universe, as well as to Smith's two ‘causal loop’ arguments. The problem with all four arguments is their reliance on Hume's principle that to explain the members of a collection is ipso facto to explain the collection. This principle succumbs to counterexamples. The third point is that, even if Hume's principle were true, Smith's argument could not succeed without the aid of a theory of causation according to which causation is production (causation of existence).

As all microscopists are taught, resolution can be measured by knowing the closest distance between two points that can be discriminated in the image. There are some occasions when we want to measure something in a digital image, and the nominal resolution isn't sufficient for the task. One of these, extracting a contour from the image, was summarized in a previous research report. The principles would be valid for any filled area, such as a particle or structure from an X-ray dot map. The ground rule was set that the outermost pixel would be selected at every point on the contour. It was clear from the geometry shown in Fig. 1 that only values of 0°, 45°, 90°, 135° and 180° could be measured. Because of the stair step defect, tracing the sequence of pixel locations only gave offsets to 8 pixels, one directly below, two on the corners below, three pixels in the same location above, and one pixel on either side of the subject pixel. Therefore it was impossible to measure the true curvature of the contour.

Annotation:

The visual culture forming part of India’s ‘inheritances’ is staggering in scale, diversity and range. However, we need further comprehensive documentation, publications, and innovative steps like museums devoted to ‘heritage’ and popular visual cultures etc., and a national archive of heritage monuments, accessible to all. Further, while sites and art belonging to ancient and medieval times get attention other periods, like treasures of the nineteenth century, are often overlooked. In part, the social mind-set and attitude towards art reinforced by an imbalanced system of education, is to blame. Art is equated with hobby or entertainment, and rarely with vocation or profession. There is also a clear division between verbal and visual cultures. Most educated people are brought up on verbal cultures; a few respond to performing arts and only a fraction are visually literate. A people’s movement for a cultural resurgence free of chauvinistic objectives is required. Such a movement could counter the consumerism and brutalization that seems to have swept the minds of a growing generation. It could be a national agenda.

Carruthers argues that natural language is the medium of non-domain-specific thought in humans. The general idea is that a certain type of thinking is conducted in natural language. It’ not exactly clear, however, what type of thinking this is. I suggest two different ways of interpreting Carruthers’ thesis on this point and argue that neither of them squares well with central-process modularism.

Abstract In this paper, I investigate the issue of the contingency and inevitability of science. First, I point out valuable insights from the existing discussion about the issue. I then formulate a general framework, built on the notion of contrastive explanation and counterfactuals, that can be used to approach questions of contingency of science. I argue, with an example from the existing historiography of science, that this framework could be useful to historians of science. Finally, I argue that this framework shows the existing views on historical contingency and counterfactuals in a new light. The framework also shows the value of existing historiography in philosophical debates.

The mathematical model was established, the pragram was made to optimize the lengths and angles of each link by means of inner point penalty function method. Involving 12 scheduled points, the track of a certain point on the coupler of a planar four-bar linkage was realized and previewed using Matlab. The optimum program presented here could enhance the design efficiency and insure the design accuracy markedly. By this method the coupler-curve involving more than or less than 12 points could be realized, and more complex multi-linkage could be designed.

Abstract:This article argues that practicality is currently overemphasized in philosophical contributions to bioethics. The inclinations to aim at relevance, to ground normativity on common morality, and to involve many academic disciplines in ethical discussions is understandable, but they are all poorly founded. When answers to difficult questions are already known at the outset, these endeavors can help decisionmakers in gaining the acceptance of the general public. Wider theoretical analyses, in which philosophers could excel, however, tend to be lost in these practical enterprises.

Abstract. Thermal inspection of a building is a very important part of facility management. This paper presents the methodology how to capture thermal images on a case of a family house, how to process thermal images using current photogrammetric method and how to achieve point cloud where each point is enhanced by information about temperature. This enhanced point cloud could be data for BIM or GIS and could be a valuable result for facility managers where they can detect thermal leaks or anomalies. Due to the point cloud, the thermal leaks or anomalies could be easily located and described. The accuracy of the point cloud is tested by check points and the resulted point cloud is compared with point cloud gathered by a laser scanner. The last part of the paper is devoted to a discussion about the results and outputs of the photogrammetric processing of thermal images.

AbstractFrom an anatomical point of view, recurrences at the saphenofemoral junction (SFJ) could result from various sources. For one, it could be caused by a recanalisation of an originally occluded great saphenous vein (GSV). Secondly, another vein in the junction region could take over the function of the GSV and dilate. A third variation is a – more or less successful – generation of a new vein. In the last case, a sufficient vein could be generated, an insufficient vein could arise, or an inadequate venous regeneration, so that a cluster of frail but incomplete vasculature remains (neovasculature).

Annotation:

Nearly every important measure of the US–China competition demonstrates broad-based US primacy but trend lines that favour China. The military aspects of the intensifying competition for hegemony will be borne chiefly by navies operating in the increasingly crowded Indo-Pacific—the great artery of global trade. Primacy will belong to the power that controls the sea. China’s Navy, which is in the late stages of a significant modernization effort, poses an acute challenge to the US. Without vigorous engagement and investment in deterrent capability, the US may lose its regional predominance, presenting grave strategic consequences. This article explains the strategy animating Chinese actions and makes the case for why continued American leadership is benign and beneficial. The hyperbolic assertions regarding the defence balance, familiar to China watchers, are tempered by often overlooked, but important, indicators including comparative order of battle, military logistics capabilities, global basing infrastructure, alliance military power, personnel quality (including per-soldier spending, outfitting and education), stocks of modern military equipment and perhaps most importantly projectable military force.

Background: The positioning of the stent at the flow-limiting segment is crucial for patients with extensive airway obstruction to relieve dyspnea. However, CT and flow-volume curves cannot detect the area of maximal obstruction. Objectives: The aim of this study is to physiologically evaluate extensive airway obstruction during interventional bronchoscopy. Methods: We prospectively measured point-by-point lateral airway pressure (Plat) at multiple points from the lower lobe bronchus to the upper trachea using a double-lumen catheter in 5 patients. The site of maximal obstruction was evaluated continuously to measure point-by-point Plat at multiple points when the airway catheter was withdrawn from the lower lobe bronchus to the upper trachea. Results: Remarkable pressure differences occurred at the site of maximal obstruction assessed by point-by-point Plat measurements. After initial stenting in 1 case, migration of the maximal obstruction to a nonstented segment of the weakened airway was seen with extensive stenosis from the trachea to the bronchi. In the second case, in addition to radiological analysis, point-by-point Plat measurements could identify the location of the maximal obstruction which contributed to dyspnea. Conclusions: Point-by-point Plat measurement could be used to detect the site of maximal obstruction physiologically. Furthermore, Plat measurement could assess the need for additional procedures in real time in patients with extensive airway obstruction.

Aim This study is the second report from a single experiment planned to determine if acupuncture at LI4 and SP6, or at the sacral points, could produce any harm in the pregnancy outcome of Wistar rats, as has been hypothesised in traditional knowledge. Here, we observe if these points can be harmful to the health of pregnant Wistar rats. Methods A total of 48 pregnant Wistar rats were randomly divided into 4 groups: total control, where rats were left in cages without manipulation; anesthetised control, where rats were manipulated and anesthetised but did not receive electroacupuncture; and peripheral point and sacral point groups, where rats were anesthetised and received 6 sessions of electroacupuncture at 4 acupuncture points: LI4 and SP6, and BL27 and BL28, respectively. In the 19th day of pregnancy the rats were killed and examined. The primary endpoints were levels of glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT) creatinine and histological changes of liver and kidney. Results There were no differences between the levels of biochemical parameters. No differences were also seen regarding the histopathological analysis. Conclusions We found no evidence that acupuncture at the LI4, SP6 and sacral points could be harmful to the Wistar rat dams.

The point-to-point swing arm test is very important for large arms which have swing arm movement. Traditional point-to-point swing arm controller is relay control mode. The mode has many shortcomings, such as big volume, high power consumption, low stability, and so on. An intelligent point-to-point swing arm controller, using MCU as the control core, was designed for this reason. It was mainly composed of switch signal detecting module, solenoid valve drive module, USB storage interface module and MCU control module. According to the requirements of test, the controller was able to detect the valid signal of limit switch and control commutation operation of solenoid valve, meanwhile it could record the movement time between one point and another point, the time the arm swayed and the moment information, and these above information would be stored in USB memory. It has some advantages of small size, low power consumption, high stability and flexible functions.

In the analysis of dam displacement data, mostly, a single point is used for calculation. Based on the concept named Time-displacement, this paper proposes a new calculation method with multi-point, which can make up the scarcity of analysis on the data of the dam deformation for a long time. Based on the concept of Time-displacement, the method of building the multi-point model is as follows: firstly, according to the deformation monitoring period, displacement data of all monitoring points on the deformation body, can be converted into the displacement rate. And based on displacement rate value, an appropriate rate threshold can be chosen; the rate threshold based on the experience can be used many also. Then the number of every monitoring point exceeding the rate threshold throughout the monitoring period can be recorded, and according to the number, the monitoring points’ Time-displacement could be divided into different levels. If the number of monitoring points on the deformation body is less, the interpolation points would be laid along the direction of the original monitoring sites. By the method of decision tree classification, the interpolation points’ Time-displacement could be figured out. Finally, with the original monitoring points and the interpolation points, the figure about deformation body’s Time-displacement could be drawn, which can reflect the displacement situation about the deformation body more dynamically.

This study examined the characteristics of a variable three-point Gauss quadrature using a variable set of weighting factors and corresponding optimal sampling points. The major findings were as follows. The one-point, two-point, and three-point Gauss quadratures that adopt the Legendre sampling points and the well-known Simpson’s 1/3 rule were found to be special cases of the variable three-point Gauss quadrature. In addition, the three-point Gauss quadrature may have out-of-domain sampling points beyond the domain end points. By applying the quadratically extrapolated integrals and nonlinearity index, the accuracy of the integration could be increased significantly for evenly acquired data, which is popular with modern sophisticated digital data acquisition systems, without using higher-order extrapolation polynomials.

The point cloud generated by multiple image matching is classified as an unstructured point cloud because it is not regularly point spaced and has multiple viewpoints. The surface reconstruction technique is used to generate mesh model using unstructured point clouds. In the surface reconstruction process, it is important to calculate correct surface normals. The point cloud extracted from multi images contains position and color information of point as well as geometric information of images used in the step of point cloud generation. Thus, the surface normal estimation based on the geometric constraints is possible. However, there is a possibility that a direction of the surface normal is incorrectly estimated by noisy vertical area of the point cloud. In this paper, we propose an improved method to estimate surface normals of the vertical points within an unstructured point cloud. The proposed method detects the vertical points, adjust their normal vectors by analyzing surface normals of nearest neighbors. As a result, we have found almost all vertical points through point type classification, detected the points with wrong normal vectors and corrected the direction of the normal vectors. We compared the quality of mesh models generated with corrected surface normals and uncorrected surface normals. Result of comparison showed that our method could correct wrong surface normal successfully of vertical points and improve the quality of the mesh model.

Data in the form of sets of points, irregular distributed in a region of space could be identified in varies biological applications for examples the cell nuclei in a microscope section of tissue. These kinds of data sets are defined as spatial point patterns and the presentation of the positions in the space are defined as points. The spatial pattern generated by a biological process, can be affected by the physical scale on which the process is observed. With these spatial maps, the biologists will usually want a detailed description of the observed patterns. One way to achieve this is by forming a parametric stochastic model and fitting it to the data. The estimated values of the parameters could be used to compare similar data sets providing statistical measures for fitting models. Also a fitted model can provide an explanation of the biological processes. Model fitting especially for large data sets is difficult. For that reason, statistical methods can apply with main purpose to formulate a hypothesis for the implementation of biological process. Spatial statistics could be implemented using advance statistical techniques that explicitly analyses and simulates point structures data sets. Typically spatial point patterns are data that explain the location of point events. The author’s interest is the investigation of the significance of these patterns. In this work, an investigation of biological spatial data is analyzed, using advance statistical modeling techniques like kriging.

According to actual requirements and situation, a novel automatic image registration algorithm was presented based on bag of words and features point. Firstly, pyramid delaminating was used to preprocess the pre-registration images. Then, image normalized could be obtained. Secondly, the dense SIFT features points could be extracted. The paper could get the feature eigenvectors descriptions of image by k-means clustering algorithm. Thirdly, the feature eigenvectors descriptions of image were train and the reference and pre-registration images were classification through Support Vector Machine (SVM). Finally, image registration could implement by features matching points. The results of experiment with the with office room and building test images shown the proposed algorithm was effective and could obtain the better registration image.

Abstract The ${\lambda }$-calculus enjoys the property that each ${\lambda }$-term has at least one fixed point, which is due to the existence of a fixed point combinator. It is unknown whether it enjoys the ‘fixed point property’ stating that each ${\lambda }$-term has either one or infinitely many pairwise distinct fixed points. We show that the fixed point property holds when considering possibly open fixed points. The problem of counting fixed points in the closed setting remains open, but we provide sufficient conditions for a ${\lambda }$-term to have either one or infinitely many fixed points. In the main result of this paper we prove that in every sensible ${\lambda }$-theory there exists a ${\lambda }$-term that violates the fixed point property. We then study the open problem concerning the existence of a double fixed point combinator and propose a proof technique that could lead towards a negative solution. We consider interpretations of the ${\lambda } {\mathtt{Y}}$-calculus into the ${\lambda }$-calculus together with two reduction extension properties, whose validity would entail the non-existence of any double fixed point combinators. We conjecture that both properties hold when typed ${\lambda } {\mathtt{Y}}$-terms are interpreted by arbitrary fixed point combinators. We prove reduction extension property I for a large class of fixed point combinators. Finally, we prove that the ${\lambda }{\mathtt{Y}}$-theory generated by the equation characterizing double fixed point combinators is a conservative extension of the ${\lambda }$-calculus.

This paper proposes a method to detect cutting points on tomato peduncles using a harvesting robot. The main objective of this study was to develop automated harvesting robots. The harvesting robot was equipped with an RGB-D (Red, Blue, Green, and Depth) camera to detect peduncles and an end effector to harvest tomatoes. Robots must be able to detect where to cut crops during harvesting. The proposed method was used to detect the cutting points on peduncles using a point cloud captured by the RGB-D camera. Our robot was used to identify the cutting points on target tomato peduncles at an actual farm to demonstrate the effectiveness of our approach experimentally. Using the proposed method, the harvesting robot could detect the cutting points on tomatoes.

Indoor mapping and modelling requires that acquired data be processed by editing, fusing, formatting the data, amongst other operations. Currently the manual interaction the user has with the point cloud (data) while processing it is visual. Visual interaction does have limitations, however. One way of dealing with these limitations is to augment audio in point cloud processing. Audio augmentation entails associating points of interest in the point cloud with audio objects. In coarse scan registration, reverberation, intensity and frequency audio cues were exploited to help the user estimate depth and occupancy of space of points of interest. Depth estimations were made reliably well when intensity and frequency were both used as depth cues. Coarse changes of depth could be estimated in this manner. The depth between surfaces can therefore be estimated with the aid of the audio objects. Sound reflections of an audio object provided reliable information of the object surroundings in some instances. For a point/area of interest in the point cloud, these reflections can be used to determine the unseen events around that point/area of interest. Other processing techniques could benefit from this while other information is estimated using other audio cues like binaural cues and Head Related Transfer Functions. These other cues could be used in position estimations of audio objects to aid in problems such as indoor navigation problems.

How do you comprehensively analyze the chemistry of a microstructure with an SEM equipped with an energy-dispersive x-ray spectrometer (EDXS)? Prior to the 1990's there would have been perhaps two distinct and commercially available solutions to this problem. Firstly, you could have collected a number of point spectra each with a large number of counts and individually analyzed each one. The positive aspect of this, in principle, is that for each point the elemental correlations are maintained (e.g., a given point contains Al and O). The potential problem is that the region of the point analysis in question is not representative of the microstructure as a whole or subtle differences between different points could be missed. Additionally, point analyses are quite subjective and prone to missing potentially important regions of the microstructure.
