Abstract

Cyber-Physical Systems (CPS) are networks of embedded systems with the integrations of computation and physical processes. Modern cars consist of many ECUs, which form a complex environment of embedded network, a typical vehicular CPS. This paper analyses the features of vehicular CPS software in depth such as heterogeneity and distributed, then we propose a modeling method for vehicular Cyber-Physical System with extended hybrid automata as formal modeling tools from the perspective of service providing, treating the monitor and control device entities as device services respectively. At last, a case of the vehicle speed control system shows the validity of the modeling method.

Abstract

Nowadays, UML is applied to modeling in the analysis and design of software systems widely. However, modeling the system by different UML diagrams certainly will introduce inconsistency between UML diagrams. A method model checking the consistency between Statechart Diagram and Sequence Diagram in UML 2.0 is given. Firstly, XYZ/E can express the mechanism of state transformation and formal semantics, so it can characterize Statechart Diagram directly. Secondly, XYZ/E and Promela are similar in many aspects; an algorithm transforms the XYZ/E code into promela is proposed. In the follow, the rules which describe how to use LTL to express the interaction fragments in UML2.0 sequence diagram are given. Finally, the consistency between the two diagrams is verified by checking whether the LTL formula is the property of the model described by Promela.

Abstract

Program slicing is a technique for analyzing program by focusing on the statements which have dependence relations with slicing criterion. Slicing has applications in testing and debugging, re-engineering, program comprehension and software maintenance. Program verification is an important method in assuring the correctness and reliability of computer hardware and software. One of the major problems is space-explosion in the application of this method to concurrent software systems: state space grows exponentially in the number of concurrent components. In fact, it is often the case that some of the statements of the program are irrelevant to the verified property and can be deleted. In this paper, we introduce an approach for slicing concurrent object-oriented programs to reduce state space in the process of program verification. Firstly, we define the dependencies between statements in the given program. Then present the method of extracting slicing criterion from linear temporal logic property and propose the steps of computing slicing. We also discussed that the satisfaction of the verified LTL property is guaranteed for both programs before and after slicing, and at the same time the number of states in state transition graph is decreased.

Abstract

We first get the shape approximately of man's chest circumference by Trace-point method, and draw circumscribed curve, then fit the curve with several functions and find out the best. Finally we modify it and obtain the function relation between the man's chest circumference and the width and thickness of his chest, and figure out other man's chest circumference in the same sort. Our method was proved that the errors can be accepted. [ABSTRACT FROM AUTHOR]

Abstract

In order to understand the composition and accumulation characteristics of phthalates esters (PAEs) in agricultural soils in Gansu province, a total of 41 soil samples from four agricultural soils in Gansu province were collected, and the content of six PAEs compounds was analyzed using a gas chromatography-single quadrupole mass spectrometer (GC-MS). The results showed that the average value of PAEs compounds in agricultural soils in Gansu province was 432.4 μg·kg -1 . The detection rates of DMP, DEP, DnBP, DEHP, and DNOP in the soil were 100%, and BBP was not detected. The order of the average value of PAEs content in the four agricultural soils in Gansu province was:greenhouse>farmland (open field)>forest>grassland. The exceeding rates of dibutyl phthalate (DnBP), dimethyl phthalate (DMP), and dimethyl phthalate (DEP) were 94%, 28%, and 27%, and the remaining three did not exceed the standard. The composition of PAEs in different agricultural soils was different due to their different sources. DEHP and DnBP components in the six different PAEs monomers accounted for a higher proportion and were the main pollutants of PAEs in agricultural soils in Gansu province. In this study, the contents of soil PAEs and DEHP were significantly positively correlated with the residual amount of mulch film in the farmland ( P <0.05). In general, the content of soil PAEs in the Hexi area of Gansu province was significantly higher than that in the Longdong area.

43. Posterior decompression and short segmental pedicle screw fixation combined with vertebroplasty for Kümmell's disease with neurological deficits.

Author

Abstract

The aim of this study was to investigate the treatment of Kümmell's disease with neurological deficits and to determine whether intravertebral clefts are a pathognomonic sign of Kümmell's disease. A total of 17 patients who had initially been diagnosed with Kümmell's disease were admitted, one patient was excluded from this study. Posterior decompression and vertebroplasty for the affected vertebrae were conducted. Pedicle screw fixation and posterolateral bone grafts were performed one level above and one level below the affected vertebrae. Vertebral tissue was extracted for histopathological examination. The mean time of follow-up was 22 months (range, 18 to 42 months). The anterior and middle vertebral heights were measured on standing lateral radiographs prior to surgery, one day postoperatively and at final follow-up. The Cobb angle, the visual analog scale (VAS) and the Frankel classification were used to evaluate the effects of the surgery. The VAS, anterior and middle vertebral heights and the Cobb angle were improved significantly one day postoperatively and at the final follow-up compared with the preoperative examinations (P<0.05). No significant differences were observed between the one-day postoperative results and those at final follow-up (P>0.05). The neurological function of all patients was improved by at least one Frankel grade. All patients in this study exhibited intravertebral clefts, and postoperative pathology revealed bone necrosis. One patient (not included in this study) showed an intravertebral cleft, but the pathology report indicated a non-Hodgkin's lymphoma. The intravertebral cleft sign is not pathognomonic of Kümmell's disease. Posterior decompression with short-segment fixation and fusion combined with vertebroplasty is an effective treatment for Kümmell's disease with neurological deficits.

Abstract

Objective: To investigate the influence of continuous high-volume hemofiltration (CHVHF) on interleukin 1 receptor-associated kinase-4 (IRAK-4) and tumor necrosis factor-alpha (TNF-alpha) levels in patients with severe acute pancreatitis (SAP)., Methods: Forty-one patients with SAP were randomly divided into two groups to receive treatment with CHVHF plus conventional therapy (21 patients) and conventional therapy only (20 patients). Venous blood samples were taken before and 12, 24, and 72 h after the treatment for evaluation of APACHE II scores. The mRNA and protein levels of IRAK-4 in the monocytes were determined by real-time PCR and Western blotting, respectively, and serum TNF-alpha levels was detected using enzyme-linked immunosorbent assay (ELISA)., Results: Among the 21 patients receiving CHVHF, 18 survived and 3 died, and in the conventional therapy group, death occurred in 5 cases. In the surviving patients of CHVHF group, the APACHE II scores, IRAK-4 mRNA and protein levels and TNF-alpha levels were all significantly lowered after the treatment, and these indices were also significantly lower than those in the conventional group after treatment (P<0.05)., Conclusion: CHVHF is effective in reducing monocyte IRAK-4 levels and serum TNF-alpha level in SPA patients, and thus alleviates the symptoms and improves the prognosis of SAP, possibly by reducing the level of the activators that induce monocyte activation via the Toll-like receptor.
