Adenosine triphosphate (ATP) biosensor has been widely used in biochemistry, molecule biology and food industry in recent years. Meanwhile, screen-printing technology has been applied in electrochemical researches owing to their advanced properties. A dual enzyme ATP biosensor based on co-immobilization of glucose oxidase and hexokinase on screen-printed electrode was developed in this work. The fabrication...
Given the emergence of veriflable computation, it has made an approach to deal with the security bottlenecks in cloud computing. In this paper, we present two public veriflable delegation schemes for polynomials and matrix multiplication. Since cloud providers may not be trusted, a weak client will outsource a function f and encoded input sx. After evaluating, the server returns related result along...
Traffic light is regarded as one of the most effective ways to alleviate traffic congestion and carbon emission problems. However, traditional traffic light cannot meet the challenges in traffic regulation posed by the fast growing number of vehicles and increasing complexity of road conditions. In this paper, we propose a dynamic traffic regulation method based on virtual traffic light (VTL) for...
VCPS (Vehicular Cyber Physical Systems) is a special kind of networked cyber physical system in which each vehicle is regarded as a communication unit. Vehicle's movement is restricted by road and environment in VCPS, while traditional random mobility model and waypoint mobility model cannot reflect the realistic vehicle traces. In VCPS, with the high speed of vehicles, the network topology undergoing...
The motivation of the special session was to allow engineering educators and researchers to explore different cultural perspectives of engineering ethics, and understand how that would affect both individual and team ethical decision-making. This will inform how we teach and assess engineering ethics, especially in diverse project teams, and equip educators with tools for using these instruments as...
In engineering ethics, the traditional approach views engineers as individual moral agents who are capable of making autonomous decisions. However, the broader context in which engineers work and make their ethical decisions is often overlooked. In teaching engineering students, institutional climates help define how educational programs, curricula, and pedagogical modules are designed with some values...
Engineering is becoming an increasingly global profession, requiring interaction with diverse sets of people from different countries, cultures, and traditions. This diversity introduces more social and ethical complexity to the profession and highlights the importance of enabling engineers to work collaboratively and develop strong ethical decision-making skills. This study examines the relationship...
Hybrid energy storage system (HESS) can achieve a better overall performance by combining power-type storage and energy-type storage. The combination enables active distribution network (ADN) to regulate power flow and manage energy more economically and realize active control. This paper analyzes the technical characteristics of the HES S to propose a control strategy of HESS applied in ADN at first...
Complicated dynamic behavior of nonlinear Four degree-of-freedom (DOF) semi-vehicle model will happen under pavement roughness incentive. In this paper, the consecutive speed control humps (SCHs) dynamic excitation function is presented. And the model can be analyzed by velocity bifurcation diagram, Poincaré map, phase diagram and power spectrum. The range of velocity is obtained under chaos vibration...
Multidisciplinary project teams in engineering education allow students to gain experience with engineering on a professional and practical level, while still maintaining a supportive learning environment. This context reflects the team-based and multidisciplinary nature of much professional engineering work. In an increasingly complex environment that requires collaboration across cultures and disciplines,...
There remain many opportunities to enhance how the ethical dimensions of science and engineering are taught and assessed. In fact, current trends suggest growing demand for STEM professionals who can deftly navigate the wide range of moral and ethical issues that might be faced during their careers, whether in the private, academic, government, and/or non-profit sectors. Yet even when high quality...
In wireless sensor network (WSN), real-time network applications require good quality-of-service (QoS) guarantees, such as low packet delay and small backlog. Differentiated services (D-iffServ) mechanism is proposed to satisfy the QoS requirements in WSN. The stochastic characteristics need to be considered for the QoS performance analysis of DiffServ-based WSN. However, the existing works merely...
In hybrid wireless network (HWN), delay is always an important parameter to evaluate the QoS performance. Previous works have studied the average delay of all transmitted packets. However, QoS guarantee is commonly provided for a certain data flow. In this paper, a stochastic network calculus (SNC) based approach is proposed to analyze the stochastic end-to-end delay of a data flow through HWN. Linear...
In this paper, it was investigated and evaluated about characteristics of nitrogen pollution for 11 sampling water or surface sediments (0~10cm) in Hang Zhou Xixi Wetland, and correlation analysis was conducted amongst nitrogen indexes for water and that for surface sediments. The results revealed that nitrogen nutrient loading was generally serious in water of Xixi Wetland, total nitrogen(TN) and...
Recent development in logistics has led to wide use of fourth-party logistics (4PL) and third-party logistics (3PL) service providers. Given the increase of the supply chain complexity and growth of intense competition, these logistics service providers (LSPs) face increasing challenges. A viable way is to cooperate. This paper aims to apply the principal-agent theory to the logistics industry by...
In a P2P video-on-demand (VoD) system, the asynchronous characteristic of users' random seeking makes data sharing among peers more challenging, and raises very high capability requirement of the source video server. In this paper, we propose adding one more server in a P2P VoD system to support the random seeking operations and investigate the capacity dimensioning problem for the new server. We...
Small watershed soil erosion monitoring system is the basis for the research of soil erosion. In this for typical karst underground river basin water and soil loss is analyzed, in the condition of remote sensing technology and GIS, the author explores the karst underground river basin in soil erosion monitoring system of the objectives and tasks, the design of monitoring procedures, puts forward the...
Emergency Response Plan is the core and criteria of emergency response incidents process, which should be formalized further for the reason of improving its sharing and interoperability. In this paper, combined with van der Aalst's meta-model, we expanded the model to be a plan-program ontmodel, regarded the plan as a template with constraints and variables, described constraints of time, space, roles...
Radiology departments could benefit from the digital dashboards which integrate and visualize information reflecting workflow state. However, the heterogeneous environment in radiology prevents an integrated overall view of the process. The objective of this study is to design and develop a workflow-based dashboard in a heterogeneous environment to help the radiology administrators and managers monitor...
This paper studies the asymptotic properties of the limiting zeros of discrete-time system corresponding to continuous-time multivariable plants with the degrees of infinite elementary divisors two or three, i.e., mu1 = middotmiddotmiddot = mum-k = 2 and mum-k+1 = middotmiddotmiddot = mum = 3 (0 les k les m). The linear approximate expressions with respect to the asymptotic behavior of the limiting...
