what is the threat and solution for when alice sends a password and bob hashing it and comparing it against a database of hashed passwords? Solution In given scenario, dictionary attack may be the possible threat in which hacker tries to get the decipher key by trying million of possibilities like in dictionary. There are various data types of dictionary attack software in the market which ease the work of a hacker. Possible solution for the given threat is using salt which is a random data which is used an additional input for the hashing. A new salt is generated for each password. Generated salt and password are concated and applied to hash function and obtained result is stored in the database with salt value. Since, salt is different for each password, therefore it can be used for common passwords as well. For example, salt is used in UNIX system credentials, Internet security etc..

Describe the E-C and the players involved in the electrical and mechanical events leading to the skeletal muscle contraction and relaxation. Use the following terms in your description: chemically-gated ion channels, Na+ voltage-gated, K+-voltage-gated channels, threshold, calcium, end plate potential, motor unit, muscle fiber (myocyte) (muscle cell), Acetylcholine, acetyl choline esterase, sarcolemma, T tubules, latent period, contraction period, relaxation period, refractory period, SR, cross bridges, ATP, troponin, tropomyosin, myosin, actin, sarcomere, z discs, sarcomere, contraction, relaxation. Solution A rapid and large change in membrane potential of excitable cells (such as nerve cells) during which the potential actually reverses so that the inside of the excitable cell transiently becomes more positive than the outside is termed as action potential. Action potential allows communication over long distances within the body. An action potential in a muscle fibre is called muscle action potential, when an action potential occurs in a nerve cell, it is called a nerve action potential (nerve impulse). Skeletal muscle consists of numerous bundles called fascicles. Each fasciculus is composed of numerous muscle fibers (or muscle cells) and each individual muscle cells is surrounded by connective tissue called the endomysium. The cell membrane of the muscle fibre is called the sarcolemma. the sacoplasm is the specialized cytoplasm os a muscle fibre that contains a modified ER known as the sarcoplasmic reticulum. Transverse (T) tubules invaginate the sarcolemma, allowing impulses to penetrate the cell and activate the sarcoplasmic reticulum. Sarcoplasm contains fine thread like contractile structure called myofibrils. In each myofibrils actin thin filaments and myosin thick filaments are organized into a linear chain of highly ordered structure called sacomeres, the basic functional unit of a myofibril. One end of the thin filaments is attached at their plus ends to the Z disc. Thin filaments contain the proteins actin, nebulin, tropomodulin, tropomyosin and troponin. Tropomyosin is a fibrous molecule that consists of two chains alpha and beta, that attach to F- actin in the groove its filaments. Troponin a complex of three polypeptide troponins T, I and C ( named foe their tropomysin binding, inhibitory and calcium binding activities respectively). Four molecules of calcium ion bind per molecule of troponin. Generation of an Action Potential Across the Sarcolemma : Movements of ions occur through ion channels, ion channels may be either leaky channels or gated channels. Action potential are the direct consequence of the voltage gated cation channels. Steps of E-C coupling: 1. Action potential generated and propagated along sarcomere to T-tubules 2. Action potential triggers Ca2+ release 3. Ca++ bind to troponin; blocking action of tropomyosin released 4. contraction via crossbridge formation; ATP hyrdolysis 5. Removal of Ca+2 by active tra.

Harden, Harden, & Harden is a venerable Wall Street stock brokerage firm. It has its business offices located in downtown Manhattan in the Wall Street district. Its information technology offices are located across the Hudson River in Jersey City. One of HHH’s most important corporate clients is Mammoth Capital Corporation. For years, HHH has been handling Mammoth’s financial security transactions in a semi-automated fashion. Mammoth would supply HHH with financial data generated from its financial systems formatted in accordance with Mammoth requirements. This data would have to go through a multi-step reformatting process so that HHH could deal with it. Similarly, when HHH needed to send data back to Mammoth, it would have to be reformatted so that Mammoth’s computers could accept it. It was obvious that this process was time-consuming, costly, and error prone. Mammoth approached its principal account executive at HHH and said that it would be willing to fund a project that would enable to engage in seamless financial transactions with HHH. It Assignments MGT201. Communication and Soft Skills 2013 University of Management and Technology 2 established some special requirements. For example, instructions to and queries of the system should be web-based. Also, data security protocols would have to be established to assure the financial integrity of the transactions. Songsri Singh of HHH’s Information Technology Department was put in charge of the project. She had two IT professionals to help her, including an expert on web based transactions. All three of these people worked in Jersey City, a forty minute train ride from headquarters on Wall Street. Songsri also identified four business people from headquarters. One was the account executive, who was familiar with the wants and needs of Mammoth. The other three were experts on financial processes relevant to the project’s requirements. Songsri also included a specialist from Mammoth’s IT department, who would coordinate activities from the Mammoth perspective. His name was Joseph, and he and his department were located in Phoenix, two time zones away from Songsri. Mammoth’s business headquarters were located in Chicago, one time zone away from Songsri. The project “owner” was located there. He was a Senior Vice President at Mammoth. He assured HHH that he would make three or four business experts available to help out with the project, when their expertise was needed. A careful analysis of business and technical requirements suggested that the project would take nine months to complete. While most of this time entailed standard software development, testing, and integration activity, a significant portion was also dedicated to getting approvals from senior managers in both companies at crucial milestones (e.g., HHH had a rule requiring all web-based activities of substantial size to undergo a legal review by the legal department. This review typically would take from two to six weeks). Clearly.

Every time we have to make a choice we are faced with an opportunity cost. Using an example in your professional life, identify a situation where you were presented with a choice, the opportunity cost of the choice you made, and the process you used to make your choice. As part of your discussion, explain whether or not responsible stewardship played a role in your choice. Remember to use the appropriate economic concepts and terminology that are applicable to your answer. Solution A friend of mine is a person of Indian Origin. A very bright student otherwise, she also had a keen interest in exploring her own cultural heritage. She belonged to the land of Bengal, known largely for its music and literature. Nobel Laureate, Guru Rabindranath Tagore hailed from this land of Bengal in India. He introduced the World to a very enriching music genre called, ‘Rabindra Sangeet’. The music genre is basically based on Hindustani Classical music of the country. Rabindranath’s vivid works of literature helped shape this ‘Rabindra Sangeet’ into different forms, starting from in the form of poetry to dance drama and singing. My friend was taken away by its highly beautiful lyrics that touch the heart of every person. The singing style had high modulations and requires a person to have a sound knowledge of the Hindustani classical music in order to pursue the same. My friend always had a basic knowledge of Rabindra Sangeet but had keen interest to explore it more. So, this friend passed out from Yale University with the degree in Commerce. Post that, she was working with an MNC, earning decently well. However, after 3 years of her job, she sought for the CAT exam in order to make to the Indian Institute of Management (IIM), one of the finest Management institute all across the world. And as the destiny had it, she cracked the same and went to pursue her Post Graduation in Management from IIM, Kolkata. Kolkata is the capital of the state of Bengal in India and this was her final destination. Many of her friends, including me, thought that it was rather a wishful thinking to forego a great job which none of us, in her friend’s group, could ever make it, and to settle down for a higher education outside the US. However, little did we know how serious she was about pursuing her higher education along with ‘Rabindra Sangeet’, opportunities of which, was extremely limited in the US. She spent two years very sincerely in obtaining the degree of her management from the prestigious IIM. Thereafter, she got campus recruited to the Securities and Exchange Board of India (SEBI), an autonomous body, regulating all the stock exchanges of India. Her profile in the job called with itself a lot of responsibilities. However, she had bigger plans on her mind before she would make it back to the US. My friend, enrolled herself to the evening batches of Rabindra Bharati University to seek admission to the evening batches of ‘Rabindra Sangeet’ course. She continued working with S.

A linked stack is implemented using a standard Node class as follows: import java.util.*; class stack implements Iterable {private Node top; private int size; public stack () {top = null; size = 0;} public Object pop() {if (size == 0) throw new RuntimeException (\"\"); Object answer = top.getData (); top = top.getNext (); Size --; return answer;} public void push (Object x) {Node newNode = new Node (x top); top = newNode; size++;}//the iterator method is missing} Write a class StackIterator to implement objects that can be returned by the stack iterator. Also write the missing stack method called iterator. You can decide whether the iterator will run through the data in the stack in LIFO or FIFO order (one choice is much easier).

What professions were represented on the team? What role did each member play in achieving the team’s shared goal? To what extent was your teamwork experience successful? Why or why not? (in your own words-not copy and paste) Solution According to Bernard Barett, (2016) the following professions were represented on the team: Psychologist, Counsellors, behavioural teams, nursing, social workers, Psychiatrist, Art therapist, General Practictioners. Each member play a definite role in achieving the shared role. Members share a high degree of coordination and teamwork. When individuals grasp each other well, they\'re rather more possible to figure well along. New member can stay somewhat isolated till everybody else gets to grasp her. If you\'ve got many workers on speaking terms and you throw them along into a project. I work in a healthcare organziation as a nursing staff and my experience of team was successful with lots of new experiences. When health care suppliers work as a team, they will be a lot of awake to changes as they occur, in line with a research team funded by the Canadian Health Services analysis. once a patient’s condition worsens, the team appearance to the leader, knowing that every person on the team will fulfill his various duties and work with others to resolve issues. Nurses, doctors and assistants operating as a team tend to create fewer mistakes, resulting in improved patient outcomes.Team members are more practical health care suppliers once they work along as a result of they have a tendency to be told a lot of concerning what role every member plays. you wish to know the duties of every team member to figure along effectively, increasing your own skills as duties typically overlap. As a part of the team, you come back to know and appreciate the roles of physicians, nurses, nursing assistants, social staff, physical therapists and directors as you communicate and work along within the best interests of the patient..

What is the difference between sequential file access and random file access? Describe a unique scenario (different than submitted by classmates) where each type of file access could be used (no coding required). Solution the main differenece is we should have to incremenet the address to the reach the specified loaction in sequenctial access but in random access we will get the address of the loaction and can reach it directly.(it can implemeted using pointers) sequential accesss: in this the data is accessed in a memory devices in sequencial or predefined way or in an ordered sequence example of sequencial access: iam giving you the real world senario as a example: a student named john is living in an hostel he want his friend named rock. in hostel there are 100 rooms sequencially john is in 20th room and rock is in 90 th room .but john doesnt know which room he is so he started searching one by one room sequencially like(21 22 23..90). this is one of the example for sequential access random access: it is one type of process in which specified memory can access by using address of the memory and can be accessed directly . example of random access: now if we use the above example if john known room number of the rock then he need not to search all the room he just directly reach the 90 th where rock is situated..
