A k-Coverage Scheduling Scheme in Wireless Sensor Network Based on Hard-Core Process in Rayleigh Fading Channel

Sensing coverage is a fundamental design issue in wireless sensor networks(WSNs),while sensor scheduling ensures coverage degree to the monitored event and extends the network lifetime.In this paper,we address k-coverage scheduling problem in dense WSNs,we maintain a connected k-coverage energy efficiently through a novel Hard-Core based Coordinated Scheduling(HCCS),in which hardcore is a thinning process in stochastic geometry that inhibits more than one active sensor covering any area redundantly in a minimum distance. As compared with existing coordinated scheduling,HCCS allows coordination between sensors with little communication overhead.Moreover,due to the traditional sensing models in k-coverage analysis is unsuitable to describe the characteristic of transmit channel in dense WSNs,we propose a novel sensing model integrating Rayleigh Fading and Distribution of Active sensors(RFDA),and derive the coverage measure and k-coverage probability for the monitored event under RFDA. In addition,we analyze the influence factors,i.e. the transmit condition and monitoring degree to the k-coverage probability. Finally,through Monte Carlo simulations,it is shown that the k-coverage probability of HCCS outperforms that of its random scheduling counterpart.

A Hydraulic Hammer Corer Utilizing Hydrostatic Energy for Hard Seafloor Sediment Coring

The paper presents the design and preliminary test results of a corer used for hard seafloor sediments sampling. Generally the sediment cores are provided by either gravity-type coting or deep-ocean drilling for a range of studies. However, in consideration of the operability and available sample length in collecting hard sediments, these methods exhibit no advantages. In this paper, a new corer which can exploit both hydrostatic energy and gravity energy for hard sediments coting is presented. The hydrostatic energy is provided by pressure differential between ambient seawater pressure and air pressure in an empty cavity. During sampling process, the corer penetrates into the sediment like a gravity corer and then automatically shifts to the percussion mode. The experiments in the laboratory indicate that the corer can complete 40 cycles in the sea with a cycle time of 2.8 seconds in percussion mode and impact the sample tube with the velocity of 0.2 m/s during each cycle. Besides, its adjustable falling velocity can make the corer achieve the maximum efficiency in coring different sediments.

Research on wind erosion processes and controlling factors based on wind tunnel test and 3D laser scanning technology

The study of wind erosion processes is of great importance to the prevention and control of soil wind erosion.In this study,three structurally intact soil samples were collected from the steppe of Inner Mongolia Autonomous Region,China and placed in a wind tunnel where they were subjected to six different wind speeds(10,15,17,20,25,and 30 m/s)to simulate wind erosion in the wind tunnel.After each test,the soil surfaces were scanned by a 3D laser scanner to create a high-resolution Digital Elevation Model(DEM),and the changes in wind erosion mass and microtopography were quantified.Based on this,we performed further analysis of wind erosion-controlling factors.The study results showed that the average measurement error between the 3D laser scanning method and weighing method was 6.23%for the three undisturbed soil samples.With increasing wind speed,the microtopography on the undisturbed soil surface first became smooth,and then fine stripes and pits gradually developed.In the initial stage of wind erosion processes,the ability of the soil to resist wind erosion was mainly affected by the soil hardness.In the late stage of wind erosion processes,the degree of soil erosion was mainly affected by soil organic matter and CaCO_(3)content.The results of this study are expected to provide a theoretical basis for soil wind erosion control and promote the application of 3D laser scanners in wind erosion monitoring.

Surgical treatment of severe anterior capsular organized hard core cataract: A case report

BACKGROUND Complicated cataract surgery is challenging,especially in cases of hard nuclear cataract with severe anterior capsule organization.It is important to avoid the risk of surgery and improve the surgical skills of surgeons.CASE SUMMARY A 60-year-old man presented with severe cataract and visual impairment.The anterior capsule of the lens was irregularly organized and pulled to the surrounding capsule,and white porcelain organized cord and brown-black lens nucleus were clearly visible.In phacoemulsification,maintaining the anterior capsule round and intact plays a key role in a successful surgery.In this case,if the conventional capsule treatment method was used,the anterior capsule would be torn.Therefore,we adopted a segmented anterior capsule treatment method,and a blasting method to release energy when dealing with the lens nucleus,and achieved good surgical results.CONCLUSION Complicated cataract surgery is challenging and requires precise skills.Operation plans should be made reasonably to predict the risk of surgery,and improve the visual quality of the patients.

Sintering behavior, microstructure and properties of TiC-FeCr hard alloy

TiC based cermets were produced with FeCr, as a binder, by conventional P/M （powder metallurgy） to near 〉97% of the theoretical density. Sintering temperature significantly affects the mechanical properties of the composite. The sintering temperature of 〉1360℃ caused severe chemical reaction between TiC particles and the binder phase. In the TiC-FeCr cermets, the mechanical properties did not vary linearly with the carbide content. Optimum mechanical properties were found in the composite containing 57wt% TiC reinforcement, when sintered at 1360℃ for 1 h. Use of carbon as an additive enhanced the mechanical properties of the composites. Cermets containing carbon as an additive with 49wt% TiC exhibited attractive mechanical properties. The microstructure of the developed composite contained less or no debonding, representing good wettabifity of the binder with TiC particles. Homogeneous distribution of the TiC particles ensured the presence of isotropic mechanical properties and homogeneous distribution of stresses in the composite. Preliminary experiments for evaluation of the oxidation resistance of FeCr bonded TiC cermets indicate that they are more resistant than WC-Co hardmetals.

The Theoretical Connotation and Systematic Essence of Core Competence of Agricultural High-tech Enterprises

Six representative interpretations about the core competence of the corporate proposed by the researchers both at home and abroad from different perspectives are introduced,which includes "Resource theory","Capacity theory","Integration theory of assets and mechanism","Theory of consumer surplus","Theory of institutions and systems" and "Theory of innovation". It is pointed out that although these interpretations play an active role in enriching the theory of core competence,it still faces the problems to further deepen these interpretations:the first problem is how to give a precise definition;the second is about its extension;the third is on the logical and practical relationship between the production mechanism and its sustainable competitive advantages;the fourth is the problems in the production process and the corresponding management. Both the systematic essence and features of core competence are introduced:the first is the system self-organization process produced within the corporate;the second is the interaction between corporate system and environment;it needs a growing and evolution process. This paper briefly describes the essence of core competence of agricultural high-tech corporate,introduces its five features including systematicness,integration,non-imitation,ductility and non-equilibrium,and finally explains its component parts,mainly including corporate culture system,technological innovation system,human resource system,management capability system,corporate production and marketing system,financial capability system and adaptability system.
