Response - Assignment Example This paper finds three of the statements of Brad interesting to look into further for an analysis. The highlight about the information and communication revolution brought about by the technology of Facebook, its ability to cut across social boundaries, and the growing concern about the ownership and usability of the content on Facebook are ideas that are worth scrutiny and analysis for their validity. It is, no doubt, true that Facebook has altered the way people communicate by providing a platform that surpasses the constraints of space and time. The article says â€Å"Facebook promises to change how we communicate even more fundamentally, in part by digitally mapping and linking peripatetic people across space and time, allowing them to publicly share myriad and often very personal elements of their lives† and it â€Å"reconnects regular folks with old friends and strengthens their bonds with new pals †¦help rebuild families† (Stone). This is very much true as the impact Facebook has had on the world internet users. Facebook claims on its website to have â€Å"more than 300 million active users† and it says â€Å"50% of our active users log on to Facebook in any given day† (Facebook). The extent of its influence is evident in its membership and usage. As the article says, the social networking is so powerful that it has been effectively used for activism as well. It is interesting to note that the article does not add any colour to the previous idea and the author keeps the voice low and account brief as seen in the second shortest paragraph. Secondly, the article says that Facebook has helped users build connections across socio-economic boundaries. To illustrate this, it cites the words of Mr. Zuckerberg who talks about a certain Claus Drachmann, a school teacher, who was successful in inviting Denmark’s Prime Minister for a talk in his school. This was made possible through Facebook, which otherwise would have

Integrated Technology Systems - Assignment Example Response time, hysteresis, long-term stability, sensitivity are some of uncertainties. Traceability of measurements from sensors is achieved through the implementation of regional calibration programs specific to each parameter or instrument. All sensors should have long term stability of measurements to guaranty maintenance and calibration intervals of one year or more. Temperature is the specific degree of coldness or hotness as referenced to a specific scale. A temperature sensor is used in detecting changes in physical parameters such as output voltage or resistance that correspond to the temperature change. Thermocouple is built from two electrical dissimilar metals are place at one end of a circuit. Thermocouple circuit has the most considerable temperature range when compared to other temperature sensor technologies, that is –200 to +2310Â °C. Thermistor is temperature sensor that proportionally changes its resistance in relation to temperature changes. Thermistors are of two types: negative temperature coefficient (NTC) and positive temperature coefficient (PTC). PTCs have positive change in resistance with temperature rise, while NTCs have negative change in resistance when temperatures increase. RTDs (Resistive Temperature Devices) embrace a change in electrical resistance in measuring or controlling temperature. A typical RTD has a sensing element, and connection wires to measurement instrument. RTDs are resistance devices hence generate their own heat that adds up to medium being measured. Shields/Screens that house temperature sensors affect quality of measurement of atmospheric temperature. Hence these shields/screens should reduce the effects of atmospheric and environmental factors (such as solar radiation, wind, dew). The sensors for soil temperature are configured at depth of up to 100 cm in undisturbed soil. The
