Dynamic Capabilities for Environmental Sustainability and Economic Sustainability
Economic growth and technological progress, while driving societal advancements, have also contributed to challenges such as inefficient resource utilization, social inequality, climate change, and unsustainable production. Given the dynamism of internal and external environments, the dynamic capabilities theory arises to enhance the understanding of strategic actions, particularly those aimed at gaining a competitive advantage. These capabilities are specific capabilities that contribute to both the company and market evolution through the integration of knowledge, both internal and external to the company.

Dynamic DNS
Dynamic DNS (DDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information. The term is used to describe two different concepts. The first is "dynamic DNS updating" which refers to systems that are used to update traditional DNS records without manual editing. These mechanisms are explained in RFC 2136, and use the TSIG mechanism to provide security. The second kind of dynamic DNS permits lightweight and immediate updates often using an update client, which do not use the RFC2136 standard for updating DNS records. These clients provide a persistent addressing method for devices that change their location, configuration or IP address frequently.

Dynamic Emerging Glazing Technologies
The development of the existing dynamic glazing technologies enables modulating the g-value (thus, the amount of heat) and VT (thus, the light) penetrated through the glazing while ensuring outside vision. These dynamic glazing technologies, in particular the electrochromic ones, have been proven to be more effective than traditional static glazing regarding the reduction of energy demand for air conditioning and lighting. In addition, they provide occupants’ comfort of a higher level and quality. However, the prohibitively high cost does not allow their widespread dissemination and application in the building industry. Hence, new emerging dynamic glazing technologies are currently under research or development.

Dynamic Hand Gesture Recognition
  As one of the most important tools of human-computer interaction, dynamic gesture recognition technology has attracted great attention and been applied to various industries. Meanwhile, with the advent of some high-precision deep vision sensors, the reliable data can be achieved for dynamic gesture recognition. Currently, however, the researches of dynamic gesture recognition still has certain limitations and challenges. In order to explore more methods to improve the performance of the dynamic gesture recognition, based on the Leap Motion Controller, a recognition system was proposed to recognize American Sign Language and some daily gestures.

Dynamic Packet Duplication for Industrial URLLC
The fifth-generation (5G) network is presented as one of the main options for Industry 4.0 connectivity. To comply with critical messages, 5G offers the Ultra-Reliable and Low latency Communications (URLLC) service category with a millisecond end-to-end delay and reduced probability of failure. There are several approaches to achieve these requirements; however, these come at a cost in terms of redundancy, particularly the solutions based on multi-connectivity, such as Packet Duplication (PD). Specifically, this entry proposes a Machine Learning (ML) method to predict whether PD is required at a specific data transmission to successfully send a URLLC message. This entry is focused on reducing the resource usage with respect to pure static PD.

Dynamic Positioning
Dynamic positioning (DP) is a computer-controlled system to automatically maintain a vessel's position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyrocompasses, provide information to the computer pertaining to the vessel's position and the magnitude and direction of environmental forces affecting its position. Examples of vessel types that employ DP include, but are not limited to, ships and semi-submersible mobile offshore drilling units (MODU), oceanographic research vessels, cable layer ships and cruise ships. The computer program contains a mathematical model of the vessel that includes information pertaining to the wind and current drag of the vessel and the location of the thrusters. This knowledge, combined with the sensor information, allows the computer to calculate the required steering angle and thruster output for each thruster. This allows operations at sea where mooring or anchoring is not feasible due to deep water, congestion on the sea bottom (pipelines, templates) or other problems. Dynamic positioning may either be absolute in that the position is locked to a fixed point over the bottom, or relative to a moving object like another ship or an underwater vehicle. One may also position the ship at a favorable angle towards wind, waves and current, called weathervaning. Dynamic positioning is used by much of the offshore oil industry, for example in the North Sea, Persian Gulf, Gulf of Mexico, West Africa, and off the coast of Brazil . There are currently more than 1800 DP ships.
