How would you get the temperature of an oven to a digital output? Explain the different componets of the measurment system. Solution Thermistors, like RTDs, are thermally sensitive semiconductors whose resistance varies with temperature. Thermistors are manufactured from metal oxide semiconductor material encapsulated in a glass or epoxy bead. Also, thermistors typically have much higher nominal resistance values than RTDs (anywhere from 2,000 to 10,000 ) and can be used for lower currents. Each sensor has a designated nominal resistance that varies proportionally with temperature according to a linearized approximation. Thermistors have either a negative temperature coefficient (NTC) or a positive temperature coefficient (PTC). The first, more common, has a resistance that decreases with increasing temperature while the latter exhibits increased resistance with increasing temperature. You can use PTC thermistors, or posistors, as current-limiting devices for circuit protection (in place of fuses) and as heating elements in small temperature-controlled ovens. Meanwhile, NTC thermistors, the topic of this article, are used mainly to measure temperature, and are widely present in digital thermostats and in automobiles to monitor engine temperatures. Thermistors typically have a very high sensitivity (~200 /°C), making them extremely responsive to changes in temperature. Though they exhibit a fast response rate, thermistors are limited for use up to the 300 °C temperature range. This, along with their high nominal resistance, helps to provide precise measurements in lower-temperature applications. Components of Measuring System:- The main functional elements of a measurement system are: i) Primary sensing element ii) Variable conversion element iii) Variable manipulation element iv) Signal conditioning element v) Data transmission element vi) Data presentation element. 1. Primary Sensing Element: The primary sensing element receives signal of the physical quantity to be measured as input. It converts the signal to a suitable form (electrical, mechanical or other form), so that it becomes easier for other elements of the measurement system, to either convert or manipulate it. 2. Variable Conversion Element: Variable conversion element converts the output of the primary sensing element to a more suitable form. It is used only if necessary. 3. Variable Manipulation Element: Variable manipulation element manipulates and amplifies the output of the variable conversion element. It also removes noise (if present) in the signal. 4. Data Processing Element: Data processing element is an important element used in many measurement systems. It processes the data signal received from the variable manipulation element and produces suitable output. Data processing element may also be used to compare the measured value with a standard value to produce required output. 5. Data Transmission System: Data Transmission System is simply used for transmitting data fro.

C++ Inheritance Hierarchy! Package-delivery services, such as FedEx.pdf
C++ Inheritance Hierarchy! Package-delivery services, such as FedEx\", DHL\" and UPS, offer a
number of different shipping options, each with specific costs associated. Create an inheritance
hierarchy to represent various types of packages. Use class Package as the base class of the
hierarchy, then include classes TwoDayPackage and OvernightPackage that derive from
Package. Base class Package should include data members representing the name, address, city,
state and ZIP code for both the sender and the recipient of the package, in addition to data
members that store the weight (in ounces) and cost per ounce to ship the package. Package\'s
constructor should initialize these data members. Ensure that the weight and cost per ounce
contain positive values. Package should provide a public member function calculateCost that
returns a double indicating the cost associated with shipping the package. Package\'s
calculateCost function should determine the cost by multiplying the weight by the cost per
ounce. Derived class TwoDayPackage should inherit the functionality of base class Package, but
also include a data member that represents a flat fee that the shipping company charges for two-
day-delivery service. TwoDayPackage\'s constructor should receive a value to initialize this data
member. TwoDayPackage should redefine member function caculateCost so that it computes the
shipping cost by adding the flat fee to the weight-based cost calculated by base class Package\'s
calculateCost function. Class OvernightPackage should inherit directly from class Package and
contain an additional data member representing an additional fee per ounce charged for
overnight-delivery service. OvernightPackage should redefine member function caculateCost so
that it adds the additional fee per ounce to the standard cost per ounce before calculating the
shipping cost. Write a test program that creates objects of each type of Package and tests member
function calculateCost. In your main method, ask the user what type of package they want, then
ask the user for the appropriate information for that package. Add that package to your vector of
Packages. Once the user is done entering packages, then loop through your vector and print out
mailing labels for each package (address information for sender and recipient). Also, print out
each packages cost. After your loop ends, print out the total cost for all the packages, and the
average package cost. Also, print out how many of each type of package was entered.

C++ Inheritance Hierarchy! Package-delivery services, such as FedEx.pdf
C++ Inheritance Hierarchy! Package-delivery services, such as FedEx\", DHL\" and UPS, offer a
number of different shipping options, each with specific costs associated. Create an inheritance
hierarchy to represent various types of packages. Use class Package as the base class of the
hierarchy, then include classes TwoDayPackage and OvernightPackage that derive from
Package. Base class Package should include data members representing the name, address, city,
state and ZIP code for both the sender and the recipient of the package, in addition to data
members that store the weight (in ounces) and cost per ounce to ship the package. Package\'s
constructor should initialize these data members. Ensure that the weight and cost per ounce
contain positive values. Package should provide a public member function calculateCost that
returns a double indicating the cost associated with shipping the package. Package\'s
calculateCost function should determine the cost by multiplying the weight by the cost per
ounce. Derived class TwoDayPackage should inherit the functionality of base class Package, but
also include a data member that represents a flat fee that the shipping company charges for two-
day-delivery service. TwoDayPackage\'s constructor should receive a value to initialize this data
member. TwoDayPackage should redefine member function caculateCost so that it computes the
shipping cost by adding the flat fee to the weight-based cost calculated by base class Package\'s
calculateCost function. Class OvernightPackage should inherit directly from class Package and
contain an additional data member representing an additional fee per ounce charged for
overnight-delivery service. OvernightPackage should redefine member function caculateCost so
that it adds the additional fee per ounce to the standard cost per ounce before calculating the
shipping cost. Write a test program that creates objects of each type of Package and tests member
function calculateCost. In your main method, ask the user what type of package they want, then
ask the user for the appropriate information for that package. Add that package to your vector of
Packages. Once the user is done entering packages, then loop through your vector and print out
mailing labels for each package (address information for sender and recipient). Also, print out
each packages cost. After your loop ends, print out the total cost for all the packages, and the
average package cost. Also, print out how many of each type of package was entered.

Cloning has been seen in the news and as a major topic of debate.B.pdf
Cloning has been seen in the news and as a major topic of debate.
Briefly describe the process of cloning.
What might be the benefits of cloning?
What are potential dangers or threats associated with the widespread use of cloning?
Be prepared to discuss the ethics of cloning in its various proposed forms and uses.
Please answer each question.
Solution
Cloning is a method which is used to produce an similar copy of animal cell (especially
mammals) by using genetic material of the somatic cell which can be prepared as- (a) from the
donar we will collect the nucleus and it is isolated (b) Take unfertilized eggs and remove the
nucleus (c) Insert the donar nucleus and place them in the womb and this egg is converts in to
embryo when it is fertilised and leads to production of genetically identical species.
The major benefits are - organ development/ replacement, infertility problems can be solved,
void fulfilment (but it is very less applicable), trait selection possibility etc.,
Threats- social, mental and medical consequences cannot be predicted, cell mutations can easily
possible in cloning cells which can leads to various diseases, it cannot differentiate original
organ and replicated organ.
ethically the concept of cloning is against the natural things,i.e., against god\'s creativity and the
cloned one looks like another copied one can involve in robbery, murder and there is a chance to
do unethical things..
Ascocarps (mark all that true statements) contain asci that produce.pdf
Ascocarps (mark all that true statements): contain asci that produce ascospores, which are
dispersed and germinate to form new mycelia contain asci that produce genetically Identical
ascospores contain asci, which each contain eight haploid nuclei contain gills and a cap (a
typical mushroom structure) each contain eight haploid nuclei
Solution
Ascpcarps...
Ascocarps also called ascoma, plural ascomata, fruiting structure of fungi of the phylum
Ascomycota (kingdom Fungi). The ascocarp contain saclike structures (asci) that usually bear
four to eight ascospores. ascocarps are in the form of apothecium ,cleistothecium or
perithecium.Apothecium is stalked and either disklike, saucer-shaped, or cup-shaped with
exposed asci. The largest known apothecium, produced by Geopyxis cacabus, has a stalk 1 metre
(40 inches) high and a cup 50 centimetres (20 inches) across. Cleistothecia are spherical and
must rupture or disintegrate to release their ascospores. Perithecia are globular or flask-shaped
with an apical opening for discharge of ascospores..
and prokaryotes differ. Drag and drop each phrase onto the image of.pdf
and prokaryotes differ. Drag and drop each phrase onto the image of the appropriate cell
applies to both cell types, drop it in the box that says \"Applies to both\".
Solution
Please find the answers below:
The correct matches are:
Porkaryotes:
1. Lack endoplasmic reticulum (these are membrane bound organelles hence absent in
prokaryotes)
2. DNA is in cytoplasm (Since a membrane bound nucleus is absent, DNA resides in the
cytoplasm only)
Eukaryotes:
1. Has membrane bound organelles (this is a characteristic feature of eukaryotes which separates
them from prokaryotes)
2. Has mitochondria (mitochondria represent endosymbiotic relationship of primitive bacteria in
large cells and are a characteristic feature of eukaryotes)
Applies to both:
1. Has ribosomes (both eukaryotes and prokaryotes comprise of ribosomes, though different in
structure and size for protein synthesis)
2. Has a cell membrane (the outermost periphery of the cell is surrounded by a well-defined cell
membrane in both prokaryotes and eukaryotes)
3. Makes its own protein (since both of these cells comprise of their own genetic material and
translational machinery, they are capable of synthesizing their own proteins).

How would you get the temperature of an oven to a digital output Ex.pdf
- 1. How would you get the temperature of an oven to a digital output? Explain the different componets of the measurment system. Solution Thermistors, like RTDs, are thermally sensitive semiconductors whose resistance varies with temperature. Thermistors are manufactured from metal oxide semiconductor material encapsulated in a glass or epoxy bead. Also, thermistors typically have much higher nominal resistance values than RTDs (anywhere from 2,000 to 10,000 ) and can be used for lower currents. Each sensor has a designated nominal resistance that varies proportionally with temperature according to a linearized approximation. Thermistors have either a negative temperature coefficient (NTC) or a positive temperature coefficient (PTC). The first, more common, has a resistance that decreases with increasing temperature while the latter exhibits increased resistance with increasing temperature. You can use PTC thermistors, or posistors, as current-limiting devices for circuit protection (in place of fuses) and as heating elements in small temperature-controlled ovens. Meanwhile, NTC thermistors, the topic of this article, are used mainly to measure temperature, and are widely present in digital thermostats and in automobiles to monitor engine temperatures. Thermistors typically have a very high sensitivity (~200 /°C), making them extremely responsive to changes in temperature. Though they exhibit a fast response rate, thermistors are limited for use up to the 300 °C temperature range. This, along with their high nominal resistance, helps to provide precise measurements in lower-temperature applications. Components of Measuring System:- The main functional elements of a measurement system are: i) Primary sensing element ii) Variable conversion element iii) Variable manipulation element iv) Signal conditioning element v) Data transmission element vi) Data presentation element. 1. Primary Sensing Element: The primary sensing element receives signal of the physical quantity to be measured as input. It converts the signal to a suitable form (electrical, mechanical or other form), so that it becomes easier for other elements of the measurement system, to either convert or manipulate it.
- 2. 2. Variable Conversion Element: Variable conversion element converts the output of the primary sensing element to a more suitable form. It is used only if necessary. 3. Variable Manipulation Element: Variable manipulation element manipulates and amplifies the output of the variable conversion element. It also removes noise (if present) in the signal. 4. Data Processing Element: Data processing element is an important element used in many measurement systems. It processes the data signal received from the variable manipulation element and produces suitable output. Data processing element may also be used to compare the measured value with a standard value to produce required output. 5. Data Transmission System: Data Transmission System is simply used for transmitting data from one element to another. It acts as a communication link between different elements of the measurement system. Some of the data transmission elements used are cables, wireless antennae, transducers, telemetry systems etc. 6. Data Presentation Element: It is used to present the measured physical quantity in a human readable form to the observer. It receives processed signal from data processing element and presents the data in a human readable form. LED displays are most commonly used as data presentation elements in many measurement systems.
