Issues And Trends In Healthcare Delivery System

5.7K
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...

Electrical Energy

1.3K
Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules.

Batteries and Fuel Cells

27.8K
A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Schottky Barrier Diode01:27

Schottky Barrier Diode

429
Schottky barrier diodes are specialized semiconductor devices characterized by their unique construction. This construction involves combining a metal layer with a moderately doped n-type semiconductor material. This combination leads to the formation of a Schottky barrier, a pivotal element that defines the diode's operational characteristics. The core functionality of Schottky barrier diodes is their capacity to allow current to flow in only one direction due to their distinctive...

Elements of Block Diagrams01:25

Elements of Block Diagrams

337
Block diagrams serve as a visual representation of the input-output relationships within a system. An illustrative example is a heating system, where the set temperature activates the furnace to warm the room to the desired level. Block diagrams are versatile, modeling linear systems through Laplace transform variables and nonlinear systems using time domain variables.
A block diagram typically includes essential elements such as comparators, blocks, and feedback loops. Each of these elements...

Background:

  • Blockchain technology ensures data immutability but not security at the point of data generation.
  • Secure Element (SE) technology provides trusted computing resources for IoT devices.
  • Existing IoT security solutions often lack a robust "root of trust".

Purpose of the Study:

  • To propose and validate a hybrid approach combining blockchain and Secure Element (SE) for enhanced IoT security.
  • To establish a "root of trust" for energy smart meter gateways.
  • To enable secure, decentralized, end-to-end energy trading.

Main Methods:

  • Integration of blockchain for secure distributed data storage.
  • Implementation of Secure Element (SE) for trusted data generation and computation.
  • Validation through three implementation scenarios using SE, blockchain, and LPWAN technologies.
  • Case study on an Energy Smart Metering gateway for peer-to-peer energy trading.

Main Results:

  • Demonstrated feasibility of the hybrid blockchain-SE approach.
  • Successful encryption, transmission, and saving of data using the combined technologies.
  • Overcame limitations of using blockchain or SE individually.
  • Enabled a secure and decentralized local Peer to Peer energy trading scheme.

Conclusions:

  • The hybrid blockchain-SE approach provides a robust "root of trust" for IoT platforms like energy smart meters.
  • This method enhances data security at the point of generation and ensures secure storage.
  • The validated approach facilitates secure and decentralized peer-to-peer energy trading.
