1, The full form of WSD is Word Sense Disambiguation. It’s used on Computing ,Programming & Development in Worldwide

Word Sense Disambiguation (WSD) is the process of distinguishing different meanings of the same word in different textual contexts.

In natural language processing, word sense disambiguation (WSD) is the problem of determining which “sense” (meaning) of a word is activated by the use of the word in a particular context, a process which appears to be largely unconscious in people. WSD is a natural classification problem: Given a word and its possible senses, as defined by a dictionary, classify an occurrence of the word in context into one or more of its sense classes. The features of the context (such as neighboring words) provide the evidence for classification.

A famous example is to determine the sense of pen in the following passage (Bar-Hillel 1960):

Little John was looking for his toy box. Finally he found it. The box was in the pen. John was very happy.

WordNet lists five senses for the word pen:

1. pen — a writing implement with a point from which ink flows.
2. pen — an enclosure for confining livestock.
3. playpen, pen — a portable enclosure in which babies may be left to play.
4. penitentiary, pen — a correctional institution for those convicted of major crimes.
5. pen — female swan.

3, The full form of WSD is White Spot Disease. It’s used on Animal Kingdom ,Aquatic Life in Worldwide

White Spot Disease (WSD) is a common disease of freshwater fish.

White spot syndrome (WSS) is a viral infection of penaeid shrimp. The disease is highly lethal and contagious, killing shrimp quickly. Outbreaks of this disease have wiped out the entire populations of many shrimp farms within a few days, in places throughout the world.

White spot syndrome virus (WSSV) is the lone virus (and type species) of the genus Whispovirus (white spot), which is the only genus in the family Nimaviridae. It is responsible for causing white spot syndrome in a wide range of crustacean hosts.

The disease is caused by a family of related viruses subsumed as the white spot syndrome baculovirus complex^[4] and the disease caused by them as white spot syndrome.

4, The full form of WSD is Web Services for Devices. It’s used on Computing ,Protocols in Worldwide

Web Services for Devices or Web Services on Devices (WSD) is a Microsoft API to enable programming connections to web service enabled devices, such as printers, scanners and file shares. Such devices conform to the Devices Profile for Web Services (DPWS). It is an extensible framework that serves as a replacement for older Windows networking functions and a common framework for allowing access to new device APIs.

5, The full form of WSD is Wanganui School of Design. It’s used on Academic & Science ,Universities & Institutions in New Zealand

The Whanganui School of Design (WSD) was a publicly funded tertiary institution that inhabited NZIA Heritage buildings on Taupo Quay in Whanganui, New Zealand. It is now part of the Universal College of Learning (UCOL).

6, The full form of WSD is Working Stress Design. It’s used on Academic & Science ,Architecture & Constructions in Worldwide

Working Stress Design (WSD) is a structural design method whereby a structural element is designed so that the unit stresses computed under the action of working or service loads do not exceed the specified allowable values.

Working Stress Design is called Alternate Design Method by NSCP (National Structural Code of the Philippines) and ACI (American Concrete Institute, ACI).
Code Reference
NSCP 2010, Section 424: Alternate Design Method
ACI 318M-99, Appendix A: Alternate Design Method

Notation

f_c = allowable compressive stress of concrete
f_s = allowable tesnile stress of steel reinforcement
f’_c = specified compressive strength of concrete
f_y = specified yield strength of steel reinforcement
E_c = modulus of elasticity of concrete
E_s = modulus of elasticity of steel
n = modular ratio
M = design moment
d = distance from extreme concrete fiber to centroid of steel reinforcement
kd = distance from the neutral axis to the extreme fiber of concrete
jd = distance between compressive force C and tensile force T
ρ = ratio of the area of steel to the effective area of concrete
β_c = ratio of long side to short side of concentrated load or reaction area
A_s = area of steel reinforcement
