Issues And Trends In Healthcare Delivery System

5.8K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Design Example: Automobile Ignition System01:14

Design Example: Automobile Ignition System

301
The automobile's ignition system plays a vital role by ensuring the timely ignition of the fuel-air mixture in each cylinder. This ignition is facilitated by a spark plug, which is composed of two electrodes separated by an air gap. A spark forms across this air gap when a substantial voltage is generated between the electrodes, leading to the ignition of the fuel.
One can generate a large voltage using a car battery of 12 volts with the help of inductors. Inductors are known for opposing...

Rolling Resistance: Problem Solving01:17

Rolling Resistance: Problem Solving

431
Rolling resistance, also known as rolling friction, is the force that resists the motion of a rolling object, such as a wheel, tire, or ball, when it moves over a surface. It is caused by the deformation of the object and the surface in contact with each other, as well as other factors like internal friction, hysteresis, and energy losses within the materials. Rolling resistance opposes the object's motion, requiring additional energy to overcome it and maintain movement. In practical...

Relation between Mathematical Equations and Block Diagrams01:20

Relation between Mathematical Equations and Block Diagrams

572
In a spring-mass-damper system, the second-order differential equation describes the dynamic behavior of the system. When transformed into the Laplace domain under zero initial conditions, this equation can be effectively analyzed and manipulated. The transformation into the Laplace domain converts differential equations into algebraic equations, simplifying the process of isolating the output.

Transmission Shafts: Problem Solving01:09

Transmission Shafts: Problem Solving

287
Designing a solid shaft that transmits power from a motor to a machine tool involves a series of calculations to ensure the shaft can withstand the stresses applied by bending moments and torques. First, calculate the torque exerted on the gear, considering the power transmitted by the shaft and its rotational speed. Following this, compute the tangential forces acting on the gears, which directly relate to the torque and the gear radius.
Next, use bending moment diagrams for the shaft to...

Area of Science:

  • Cybersecurity
  • Network Security
  • Blockchain Technology

Background:

  • The Internet of Vehicles (IoV) offers advanced connectivity but faces significant security challenges due to its open and self-organizing nature.
  • Existing authentication mechanisms in IoVs are vulnerable to various malicious attacks, including physical cloning and side-channel attacks.
  • The inherent openness and self-organizing characteristics of IoVs make them susceptible to malevolent activities, necessitating robust security solutions.

  • To propose a novel blockchain-enabled game theory-based authentication mechanism for securing Internet of Vehicles (IoV).
  • To address the limitations of current IoV security solutions by incorporating Physical Unclonable Functions (PUFs) and dynamic Proof-of-Work (dPoW).
  • To enhance IoV security by providing a robust defense against physical cloning and side-channel attacks, alongside other common threats.

Main Methods:

  • Development of a three-layer multi-trusted authorization solution for seamless vehicle authentication.
  • Integration of Physical Unclonable Functions (PUFs) for initial authentication and duel gaming for continuous verification.
  • Implementation of a dynamic Proof-of-Work (dPoW) consensus mechanism within a blockchain framework.

Main Results:

  • The proposed framework demonstrates superior security and functionality compared to existing solutions.
  • Achieved lower transaction and computation overhead, enhancing efficiency in IoV networks.
  • Successfully handled physical cloning and side-channel attacks, which were not addressed by previous methods.

Conclusions:

  • The blockchain-enabled game theory-based authentication mechanism provides a secure and efficient solution for IoVs.
