2.4. What are the differences between analogue and digital instruments? What advantages do digital instruments have over analogue ones? Solution Advantages of digital over analog instruments: 1) They are very easy to read. 2) Since there are very few moving parts in the electronic instruments, they are usually more accurate than theanalogue instruments. Even the human error involved in reading these instruments is very less, which adds to the accuracy of digital instruments. 3) The electronic items tend to be cheaper than the mechanical items. 4) The data from the instruments can be recorded for future reference. 5) The output of the digital devices can be obtained in the computerANALOG INSTRUMENTSDIGITAL INSTRUMENTS1.Signals in continuous fashion,gives infinite no of values in given periodIt gives finite values in given period of time2.These occupy more spaceoccupies less space3.Accuracy is poorAccuracy is good4.Chance of parallox errorno such problem5.More chances of error due to operatorvery less6.Not effects with temperatureThese are effected by temperature.

As we are moving in a World of advancement, so the security is the major concern in order to keep data isolate from the unauthorised users to access. In today’s World, we need high degree security system for the protection of our document, important data, as well as memory and jewellery. This review paper presents a secure fingerprint locker which is feasible. This system is proved successful on all norms of security of lockers. There are other methods of verifying authentication through password, RFID but this method is most efficient and reliable. To provide perfect security to the lockers and to make the work easier, this project is taking help of two different technologies, i.e. Embedded System and Biometrics. Biometrics is basically the measurement and use of unique characteristics of living beings to make them distinguish from one another. And this is more reliable then passwords and tokens which can be lost or stolen by the humans. In this paper we are providing the work done on this technique.

This research demonstrates the revealing of an advanced encryption standard (AES) encryption device key. The encryption device is applied to an ATMEGA328P microcontroller. The said microcontroller is a device commonly used in the internet of things (IoT). We measured power consumption when the encryption process is taking place. The message sent to the encryption device is randomly generated, but the key used has a fixed value. The novelty of this research is the creation of a systematic and optimal circuit in carrying the differential power analysis or difference of means (DPA/DoM) technique, so the technique can be applied in key revealing on a microcontroller device by using 500 traces in 120 seconds.

Abstract Data signal de-noising is a crucial part of every transaction which involves capturing waves and processing them into understandable format. Most essentially, this process of data signal de-noising is important in the field of military and defence. Because of the rapid development in military communication systems, a limitation arises in the systems. The limitation being - quantity of signals profoundly increases along with noise and other disturbances’ presence in the signal. In order to overcome this drawback, batch de-noising techniques are implemented on the systems to produce clean signals. In this paper, the critical analysis case of RADAR [RAdio Detection And Ranging] data de-noising by implementation of Haar Wavelet Transformation is considered. A signal set simulation containing four signals procured from RADAR data is taken into consideration. The signals are then subjected to de-noising in MATLAB and indigenously developed python tool using Haar Wavelet Transformations. The ensuing results pertaining to accuracy and efficiency of output signals are then compared. Keywords: RADAR data, MATLAB tool, Python, De-noising techniques, Haar Wavelet Transformation, Signal Simulation.

When it comes to security, we cannot overlook the concept of uniqueness. When we mention uniqueness, what comes to mind in everyone is the uniqueness that exists in every human being. This article explains the security of Cloud Computing through biometric features such as fingerprints, eye iris, retina, etc. First, the characteristics of the fingerprints that make each fingerprint unique and the sensors with which they are read are analyzed. Next, the steps of a fingerprint recognition algorithm and the disadvantages of such a system are analyzed. At the end of the article, an evaluation is made at the security level of the fingerprint recognition system.

Why is the T7 polymerase gene in E. coli strain BL21(DE3) under the control of an inducible promoter? Solution The T7 polymerase gene in E. coli strain BL21(DE3) under the control of an inducible promoter because many expression plasmids often use these \"inducible expression system\" when adding inducible promoters such as \"IPTG\" to the medium. These inducible promoters are going to prevent formation of dead cells by promoting synthesis or protein expression of T7 RNA polymerase in E coli cells finally growth phase of cells will be health to reach appropriate \"cell density\". Therefore, these inducible promoters are going to activate expression of plasmid systems using medium finally these inducible promoters control problems produced via toxic protein products formation.

What are the essential elements to have in BR/DR plans? When is a disaster considered officially \"over\"? Spell out and provide definitions for the following acronyms: COOP MTBF MTTR RPO RTO Solution Essential elements in BR/DR plans are: MTBF: Mean Time Between Failure It is a dependability term used to give the amount of failures per million hours for a product. This is the most common examination about a product’s life duration, and is significant in the decision-making procedure of the end user. MTBF is significant for business and integrators than for consumers. MTTR : Mean Time To Repair It is the time required to restore a failed hardware component. In an operational system, repair generally means restoring a failed hardware element. RPO: Recovery Point Objective It expalin the period of time that pass during the disturbance before the amount of data lost during that period exceeds the Business plan\'s maximum acceptable threshold. RTO: Recovery Time Objective It is the period of time and a service point within which a business process must be restored after a disaster in order to avoid improper penalties connected with a break in continuity..

vapour pressure equation The Clansius-Clapeyron relation relates the slope of (for example) the vapour pressure curve to latent heat L and the change in volume. Neglecting the volume of the liquid phase relative to that in the vapour phase, and assuming the latent heat to be independent of temperature and pressure (this is often valid for sufficiently short segments of the curve), show the vapour pressure equation P = const times e^-l/(RT), where l = L/n is the latent heat per mole. Solution The equilibrium between water and water vapor depends upon the temperature of the system. If the temperature increases the saturation pressure of the water vapor increases. The rate of increase in vapor pressure per unit increase in temperature is given by the Clausius-Clapeyron equation. Let p be the saturation vapor pressure and T the temperature. The Clausius-Clapeyron equation for the equilibrium between liquid and vapor is then dp/dT = L/(T(Vv-Vl)) where L is the latent heat of evaporation, and Vv and Vl are the specific volumes at temperature T of the vapor and liquid phases, respectively. More generally the Clausius-Clapeyron equation pertains to the relationship between the pressure and temperature for conditions of equilibrium between two phases. The two phases could be vapor and solid for sublimation or solid and liquid for melting. The material below is an examination of the application of the Clausius-Clapeyron equation to meteorology where the most relevant systems are water and water vapor and salt water and water vapor. But the equation also applies to ice and water vapor and ice and water. Finally there is a derivation of the Clausius-Clapeyron equation from thermodynamic principles. Note that Vv is much greater than Vl so that to a good approximation dp/dT = L/(TVv) Furthermore the ideal gas equation applies to the vapor; i.e., pVv = RT and hence Vv = RT/p where R is the universal gas constant. Thus dp/dT = L/(RT²/p) or, equivalently (1/p)(dp/dT) = L/(RT²) In differential form this is dp/p = (L/R)(dT/T²) or, equivalently d(ln(p)) = (L/R)d(-1/T) If L is independent of temperature then the solution to the differential equation is ln(p) = c0 - (L/RT) or, equivalently p = c1exp(-L/RT) where c1 is a constant..

The Vietnam War Era Discuss the range of American responses to the war. How did they change over time? How did domestic political concerns shape the country\'s response to the war? How did the war shape domestic politics in the 1960s and early 1970s? Reference: Goldfield, D. R., & In Wheeler, R. A. (2014). The American journey: A history of the United States, Combined Volume (7th ed.). Upper Saddle River, N.J.: Pearson Solution In the United States, a nationwide debate ensued over participation in the war. The government\'s official position was that it was involved in Vietnam at the request of the government of South Vietnam and was helping to repel Communist aggression from the north. Its only avowed objective was to secure a settlement that would allow the people of Vietnam to decide their own form of government. To achieve this end, it was using only carefully controlled military measures so as not to take innocent lives or bring about active participation by China or the Soviet Union. As United States involvement continued, however, Americans grew increasingly dissatisfied with their nation\'s war policy. Some, described as \"hawks,\" argued that the United States should use maximum military force to gain a quick victory. Others, called \"doves,\" argued that the conflict in Vietnam was essentially a civil war in which the United States had no right to interfere. Some of the doves demanded immediate American withdrawal, while others called for a gradual disengagement from the war. Some critics of the war charged that American use of bombers and of artillery was too indiscriminate and that many innocent civilians had perished. The revelation that United States troops in 1968 had massacred the entire population of My Lai, an enemy-held village, caused much controversy over the way in which the war was being fought. Demonstrations were held in the United States, especially in 1969 and 1970, to protest the war. As the Vietnam War progressed, it lost much support from Americans because it was clear to many that it was not justified. This caused for the country to view war as destructive, and brought about a peace movement that is mostly associated with the decade of the 1960\'s but lasted until the late 1980\'s..

Run the program until you understand what it does. a. Write the body of the method printReversed, which prints the list items in reverse order. Add a statement in main to call printReversed after the call to printList. Check ______ b. Write the body of the method printEveryOther, which prints every other item on the list, beginning with the first one. In main, replace the statement that calls printReversed with one that calls printEveryOther. Check ______ c. Write the body of the method printEvens, which prints all the even-numbered ints on the list. In main, replace the statement that calls printEveryOther with one that calls printEvens. Check ______ All this printing is getting a bit tedious. Let\'s try some more fun operations. d. 0. Add a new ArrayList-of-integer instance variable called bigList to the NumberList class Add a statement to the NumberList constructor that creates an empty ArrayList object pointed to by bigList Delete the call to printEvens from main. Write the body of the method splitList, which copies all ints that are greater than or equal to 50 from aList to bigList. Add a method to the NumberList class to print bigList. Add a sequence of method calls in main to verify that the splitList method is working correctly. I.e., after calling splitList, call again the method that prints the original list and then call the method you wrote in step 4 to print the bigList. Check _____ E. Add a method insert to the NumberList class that takes two parameters of type int. The first parameter is the index at which to insert a new number into the list, and the second is the number to be inserted. E.g., if the first param is 4 and the second is 37, then 37 will be inserted at index 4 in aList (i.e., as the new 5th list element). The number inserted does not replace the number currently at that position, but is inserted just before it. Hint: The ArrayList class has a method that does exactly this. Call that method from your insert method. Now add statements to main to allow the user to specify the number to insert and the position at which to insert it. Then, after inserting the new number, print the updated list. Check _____ F. Finally, add code to your insert method that will assure that an IndexOutOfBoundsException cannot be thrown. I.e., your insert method should just print an appropriate error message if the first parameter --- the index at which to insert the new Integer --- is illegal.
