Load And Performance Test Tools
Load testing is the process of putting demand on a structure or system and measuring its response. Software load testing The term ''load testing'' is used in different ways in the professional software testing community. ''Load testing'' generally refers to the practice of modeling the expected usage of a software program by simulating multiple users accessing the program concurrently. As such, this testing is most relevant for multi-user systems; often one built using a client/server model, such as web servers. However, other types of software systems can also be load tested. For example, a word processor or graphics editor can be forced to read an extremely large document; or a financial package can be forced to generate a report based on several years' worth of data. The most accurate load testing simulates actual use, as opposed to testing using theoretical or analytical modeling. Load testing lets you measure your website's quality of service (QOS) performance based on ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umgeni River Bridge Load Test
The Umgeni River or Mgeni River ( zu, uMngeni) is a river in KwaZulu-Natal, South Africa. It rises in the "Dargle" in the KZN Midlands, and its mouth is at Durban, some distance north of Durban's natural harbour. The name is taken to mean "the river of entrance" in Zulu, though other meanings have been proposed. The river is approximately long with a catchment area of . The Howick Falls are some famous waterfalls on the Mngeni. Tributaries A noteworthy tributary is the Msunduzi River, which joins it between Nagle and Inanda dams. Higher up its course, the Msunduzi (or 'Dusi' for short) passes through the KwaZulu-Natal capital Pietermaritzburg. A famous downriver race, the Dusi Canoe Marathon takes place between the capital and Durban, attracting thousands of canoeists for the three-day event held in January every year. A small tributary that has an impact exceeding its size and length is the Lions River which joins the Umgeni about 4 kilometers upstream of Midmar Dam (near Li ...

Reliability Testing
Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability describes the ability of a system or component to function under stated conditions for a specified period of time. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time. The reliability function is theoretically defined as the probability of success at time t, which is denoted R(t). This probability is estimated from detailed (physics of failure) analysis, previous data sets or through reliability testing and reliability modelling. Availability, testability, maintainability and maintenance are often defined as a part of "reliability engineering" in reliability programs. Reliability often plays the key role in the cost-effectiveness of systems. Reliability engineering deals with the prediction, prevention and mana ...

Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting ...
