Describe how to use sanction such that a process can send a payload with the signal that can be retrieved by the receiving process. Solution The kernel maintains two bit-vectors for every process • Every type of signal has a specific bit in this bit-vector • pending bit-vector records what signals have yet to be delivered to the process • Note: if multiple instances of a given signal occur before a process receives the signal, it will see only one instance of the signal • Signals indicate one or more events of given type have occurred • blocked bit-vector records what signals are currently not allowed to be delivered to the process • Can have a signal that is both blocked and pending • When the signal is unblocked, it will be delivered to the process • When a signal is delivered to a process, that type of signal is automatically blocked for the process • Prevents a given signal handler from interrupting itself • One kind of signal can interrupt another kind of signa A process isn’t always running when a signal is sent to it • e.g. kill() syscall is invoked by another process • e.g. a child process dies, causing SIGCHLD to be sent to parent, but a higher priority process currently preempts the parent • Kernels make a distinction between generating a signal and delivering the signal Already mentioned pending / blocked signal bit-vectors • At a coarse-grain level of detail, records which signals need to be delivered, and which signals are currently blocked from delivery • Each process also has a linked list of pending signals • siginfo_t struct records relevant details of the pending signal • Each process also has an array of “signal action” structs • Specifies how to handle each kind of signal • e.g. “default action,” “ignore,” or a user-space handler • (Flags also record other options for handling signals When a signal is sent to a process: • The kernel invokes a specific function to update the process’ signal structures, perform scheduling tasks, etc. • e.g. Linux 2.6 has specific_send_sig_info() kernel function • If the process already has a pending signal of that type, the new signal is ignored • For real-time signals, this test is skipped • Every occurrence of a real-time signal is delivered • If the process is ignoring the signal, nothing is done • No structures are updated • No scheduling tasks oc.

Everyone in the Scala world is using or looking into using Akka for low-latency, scalable, distributed or concurrent systems. I'd like to share my story of developing and productionizing multiple Akka apps, including low-latency ingestion and real-time processing systems, and Spark-based applications. When does one use actors vs futures? Can we use Akka with, or in place of, Storm? How did we set up instrumentation and monitoring in production? How does one use VisualVM to debug Akka apps in production? What happens if the mailbox gets full? What is our Akka stack like? I will share best practices for building Akka and Scala apps, pitfalls and things we'd like to avoid, and a vision of where we would like to go for ideal Akka monitoring, instrumentation, and debugging facilities. Plus backpressure and at-least-once processing.

Solution 9.The correct answer is:C) ingesting visible particles or organisms versus ingesting dissolved substances some from dead organisms. Reason:Phagotrophs ingest food particles by engulfing them while osmotrophs ingest food matter that is soluble. 10.The correct answer is: A) A proton pump that also pulls water into the vacuole. Reason:Presence of proton pump in contractile vacuole brings a difference of ions inside the vacuole as a result of which water is pulled into it via osmosis. 11.The correct answer is: A) opisthaptor Reason:Opisthaptor is the posterior attachment strcuture of the monogenean adult. 12.The correct answer is:B) formed and used only in Cnidaria although a few other organisms may steal them. Reason:Nematocysts are found only in Cnidaria but there are marine gastropods known as Nudibranchs that feed nematocysts of hydrozoids and store them in their dorsal body wall.These stolen nematocysts are known as kleptocnidae. 13.The function of the siphonoglyph is: C) to form water currents into the gastrovascular cavity. Reason: Siphonoglyph transfers water currents to the pharynx and are present at either one or both ends of the mouth of sea anemones..

At noon Joyce drove to the lake at 30 miles per hour, but she made the long walk back home at 4 miles per hour. How long did she walk if she was gone for 17 hours? How far did she walk? Solution You know that d=v*t, where d is the distance and v is the speed and t is the time, the proble give you two speeds and the total time. Lets call t1 the time that it take her to go from his house to the lake, and lets call t2 the time that it take her to go from the lake to his house. The distance from his house to the lake is constant, I mean that the distance does not change. Now lets call v1 the speed of 30mph and v2 the speed of 4mph. The time t is equalt to t=d/v distance divede by speed. Now I hope that you understand the following equation: d/v1+d/v2=t The sum of the time that take her to go to the lake from his house and the time that take her to go from the lake to his house it is the total time. Now we only have to use the given data. v1=30mph v2=4mph t=17hours d/30+d/4=17 Now we only have to solve this equation to know the total distance that she travelled. 2d+15d=1020 17d=1020 d=60 miles she travelled, and therefore the distance from his house to the lake is 30 miles..

A) If a DNA double helix that is 100 base pairs in length has 32 adenines, how many cytosines, guanines, and thymines must it have? B) Explain what is meant by the terms conservative and Semiconservative replication A) If a DNA double helix that is 100 base pairs in length has 32 adenines, how many cytosines, guanines, and thymines must it have? B) Explain what is meant by the terms conservative and Semiconservative replication B) Explain what is meant by the terms conservative and Semiconservative replication Solution A). Genes consist of specific sequences of DNA (deoxyribonucleic acid) nucleotides otherwise called “bases,” which carry the message encoding for the synthesis of a protein. There are four such bases, namely, adenine (A), thymine (T), guanine (G), and cytosine (C), which are the building blocks of DNA’s double helical structure. Chargaff proposed that, in a double stranded DNA, the ratio of purines to pyrimidines is always 1: 1. Given that the number of adenines are 32, so, the number of thymines are also 32. The remaining 36 will be guanine and cytosine, each 18 in number. B). Gene is the physical unit of heredity that transmits information from one cell to another and thereby one generation to another. DNA (deoxyribonucleic acid) is a double helical structure; it contains the organism’s genetic information in the genes which lie along the structure of DNA. During cell division, the replication of DNA occurs, which is nothing but duplication of chromosomes. DNA replication results in the formation of two new DNA helices. The semiconservative pattern of DNA replication is demonstrated by Meselson and Stahl. In this, each strand of parent DNA act as template for the new strand, thus producing two new DNA strands. So, the newly formed DNA contains one old strand and one new strand. In conservative replication, the original strands of DNA are not forwarded to the next generation, but it act as a temple for the synthesis of new DNA. So the original double helix of DNA remains intact..

Give examples of experiments that demonstrate how children\'s her reasoning changes from preoperational to concrete operational as a consequence of being able to perform reversible mental actions Solution According to Piaget\'s theory of cognitive development human development involves a series of stages and each stages prepare the chid for succeeding level. The four stages are: 1) The Sensorimotor stage: During this period infants are buzy discovering in relationship between there body and enviornment. The child has well developed sensory ability and with help of touching, seeing, sucking, feeling learn things by themselves in the enviornment. 2)The Preoperational stage: In this stage child thought is transductive means, \"Child will make inferences every identical things with same thing. as All round things with boll. then from age of 4-7 years child go through Intutive period ( egocentrism; perception dominated and intutive thought) 2a) egocentrism: in this stage child thinks that every one feels as they do and share there feeling. eg: the conversation of 2 child rohit: i love trees nisha: i am going to school. rohit: tree is green in color nisha: i will go with my mom. Here they are talking but no one is bothered what other is saying. they are just sharing there feeling. In this stage the child also begins to develop the use of symbols (but can not manipulate them), and the child is able to usethe language and words to represent the new things not visible. By the age of 4 children are developing a more complete understanding of concepts and have stopped reasoning tranductively. The pre-operational child can not classify things. for example, a child has a pile of toy vehicles which are then split into trucks and cars. Next the child is asked \'Tell me, are there more trucks than vehicles, or less, or the same number?\' the child will almost always say there are more trucks than vehicles! In the latter stage of the preoperational period, the child begins to understand between reality and fantasy. 3)The Concentrate operational stage: During this time, children begins to reason logically, and organize thoughts. In this stage there is loss of egocentric thinking. In this stage the child is able to coordinate two dimensions of an .

What are 2 ways that Alexander Hamilton’s ideas influenced the United States?? normal essay of 4 paragraph. Solution Alexander Hamilton (1757-1804) is with us every day, in our wallets, on the $10 bill. But he is with us in another sense, for more than any other Founder, he foresaw the America we live in now. He shaped the financial, political, and legal systems of the young United States. His ideas on racial equality and economic diversity were so far ahead of their time that it took America decades to catch up with them. There is no inevitability in history; ideals alone -- even the ideals of the Founding Fathers -- do not guarantee success. Hamilton made the early republic work, and set the agenda for its future. We live in the world he made; here is what he did, and how he did it. Hamilton spent much of his life in military uniform. From 1776 to 1781, in the Revolutionary War, he fought in seven major battles, as a captain of artillery, a colonel on George Washington\'s staff, and a commander of light infantry. In 1798-99, when war with France loomed, he re-entered the military as a senior officer. The American Revolution When Hamilton arrived in New York, the thirteen colonies had been protesting British taxes and commercial regulations for years. New York City was a hotbed of contending political factions, pitting Patriots against pro-British Loyalists. While still a student at King\'s College (now Columbia), Hamilton took up the Patriots\' cause, writing his first political article in 1774 (he signed himself \"A Friend to America\"). Washington\'s Aide-de-Camp In March 1777 Hamilton was promoted to colonel and appointed to George Washington\'s staff. He performed essential tasks, saw firsthand the dire consequences of Congress\'s inability to pay for adequate supplies or troops, and forged, with his Commander in Chief, the most important political bond of his life. But though Hamilton\'s work on Washington\'s staff was stimulating and important, it was also confining. He longed to return to the battlefield to win still more glory. He did so in 1781, and fought bravely at the war\'s climactic Battle of Yorktown. In 1783 the Revolution ended in victory -- and a load of debt for the newly independent nation. Foreign Policy In the 1790s, the French Revolution ignited a new series of world wars. George Washington and Hamilton desperately wanted to keep the unprepared nation out of the conflict, as Washington wrote (with Hamilton\'s help) in his Farewell Address: \"Why... entangle our peace and prosperity in the toils of European ambition?\" But when war against Revolutionary France appeared inevitable, the two veterans joined forces once again to build an effective army. Lawmaker Hamilton attended the Constitutional Convention in 1787, and helped persuade a skeptical public to ratify the Constitution by launching the Federalist Papers, a series of newspaper pieces. The first Federalist asked for laws based on \"reflection and choice,\" not .

what two things can system elements do with energy in the system? Solution Systems have a structure that is defined by its parts and processes. Systems are generalizations of reality. Systems tend to function in the same way. This involves the inputs and outputs of material (energy and/or matter) that is then processed causing it to change in some way. The various parts of a system have functional as well as structural relationships between each other. The fact that functional relationships exist between the parts suggests the flow and transfer of some type of energy and/or matter. Systems often exchange energy and/or matter beyond their defined boundary with the outside environment, and other systems, through various input and output processes. Functional relationships can only occur because of the presence of a driving force. The parts that make up a system show some degree of integration - in other words the parts work well together..

What is an Intervening Variable, Casual Prior Variable, and Partial Relationship? What is an example of each and how can they be described in statistics? Solution An intervening variable also known as mediator transmits the effect of an independent variable to a dependent variable. In industrial psychology the work environment is a major factor which leads to changes in the intervening variable of job perception and which in turn affects behavioral outcomes. Partial relationship is the correlation between two variables while controlling for a third variable. The purpose of partial relationship is to find the unique variance between two variables while eliminating the variance from a third variables. This technique is used in various experimental design where various interrelated phenomenon are studied..

Social behavior in termites does not include the reproductive isolation of a worker caste as this caste can mature to winged reproductives. List 4 reasons why termites still considerd \"social\". (Notes: these traits would Not be found in solitary insects). Solution Insects can be either solitary or social. Among the solitary insects are the housefly, which lives and hunts by itself. It has no social structure, except for breeding. Social insects live within an very organized structure, and works and lives in constant co-operation with other insects. Social insects are best exemplified by all termites (Isoptera) and ants (Formicidae) and by various bees and wasps (Hymenoptera). Species of insect qualifying as truly social, or eusocial, exhibit three traits. The first, and most important, is a reproductive division of labor. Some individuals (the queens and kings) are fertile and reproduce, whereas others (workers, or neuters) are sterile or semisterile. The workers either do not reproduce, or reproduce to a far lesser extent. The second trait is that the workers perform tasks of benefit to the colony, and in particular, cooperativelyrear the young. The third trait is that the society has some permanence and, specifically, that more than one adult generation coexists in the colony. Social insects show reproductive isolation. They usually live in colonies. They are usually differentiated in structure, function, and behaviour into castes, the major ones being the reproductives (e.g., the queen) and the steriles (workers and soldiers). Besides carrying out the basic function of reproduction, the members of the reproductive caste generally select the site for a new colony. The workers care for the eggs and larvae, collect food for other members of the colony, and construct and repair the nest, while the soldiers defend the colony against predators. The typical social insect colony is a family. In ants, bees, and wasps, the workers are all females. Males die after mating with queens and so take no part in social life. The colony therefore consists of a queen, her adult worker daughters, and the brood (eggs, larvae, and pupae) produced by the queen. The job of the workers is to rear the brood to produce new workers, new queens, and males. The new queens and males are collectively referred to as reproductives, or sexuals. The workers carry out their job by foraging for food, building or defending a nest, and feeding and tending the brood. Termite colonies have the same basic structure, except that workers are of both sexes and the queen is accompanied by a reproductive male, a king.. So, termites are called social insects..

What is the possible cause of the Pneumonia? 2) What clinical manifestations of pneumonia did Sam exhibit? Explain their pathophysiologic bases? 3)What types of infectious disease precautions should be taken related to Sam’s hospitalization? 4) What antibiotic medication is likely to be prescribed? 5) What interventions would you initiate as part of his plan of care? 6) What clinical finding would alert you that the patient is developing ARDS? 7) Based on the assessment data presented, write one or more appropriate nursing diagnoses. Solution 1. Pneumonia is an inflammatory disease that affects the alveoli sacs present in the lung. It is caused by a bacterial or a viral infection, along with certain non infectious conditions such as heart failure and diseases of the lungs. The risk factors that increase the likelihood of pneumonia in Sam are his heart condition, recent trauma, infections through long term care facility and probably a weakened immune system. The possible cause is the MRSA infection which has become the leading cause of pneumonia. 2. a. Fever- Any infection is associated with fever since the body tries to ward of the infection by increasing the body temperature. b. Increased respiratory rate (30 breaths per minute) is another symptom. The normal range of the respiratory rate is 12-13 breath per minute. The reason for this is the inflammation of the alveoli due to which the exchange of gases doesn’t take place and the pO2 (partial pressure of oxygen) decreases where the partial pressure of CO2 increases leaving an increased respiratory rate to meet the body’s oxygen demand. c. Another symptom is the O2 saturation level. O2 saturation level in Sam is 90% which is way below the normal 95%. This is again due to the decreased O2 levels in the body. This might be also due t.

8.15 Program: Playlist (C++) You will be building a linked list. Make sure to keep track of both the head and tail nodes. (1) Create three files to submit. Playlist.h - Class declaration Playlist.cpp - Class definition main.cpp - main() function Build the PlaylistNode class per the following specifications. Note: Some functions can initially be function stubs (empty functions), to be completed in later steps. Default constructor (1 pt) Parameterized constructor (1 pt) Public member functions InsertAfter() (1 pt) SetNext() - Mutator (1 pt) GetID() - Accessor GetSongName() - Accessor GetArtistName() - Accessor GetSongLength() - Accessor GetNext() - Accessor PrintPlaylistNode() Private data members string uniqueID - Initialized to \"none\" in default constructor string songName - Initialized to \"none\" in default constructor string artistName - Initialized to \"none\" in default constructor int songLength - Initialized to 0 in default constructor PlaylistNode* nextNodePtr - Initialized to 0 in default constructor Ex. of PrintPlaylistNode output: Unique ID: S123 Song Name: Peg Artist Name: Steely Dan Song Length (in seconds): 237 (2) In main(), prompt the user for the title of the playlist. (1 pt) Ex: Enter playlist\'s title: JAMZ (3) Implement the PrintMenu() function. PrintMenu() takes the playlist title as a parameter and outputs a menu of options to manipulate the playlist. Each option is represented by a single character. Build and output the menu within the function. If an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call PrintMenu() in the main() function. Continue to execute the menu until the user enters q to Quit. (3 pts) Ex: JAMZ PLAYLIST MENU a - Add song d - Remove song c - Change position of song s - Output songs by specific artist t - Output total time of playlist (in seconds) o - Output full playlist q - Quit Choose an option: (4) Implement \"Output full playlist\" menu option. If the list is empty, output: Playlist is empty (3 pts) Ex: JAMZ - OUTPUT FULL PLAYLIST 1. Unique ID: SD123 Song Name: Peg Artist Name: Steely Dan Song Length (in seconds): 237 2. Unique ID: JJ234 Song Name: All For You Artist Name: Janet Jackson Song Length (in seconds): 391 3. Unique ID: J345 Song Name: Canned Heat Artist Name: Jamiroquai Song Length (in seconds): 330 4. Unique ID: JJ456 Song Name: Black Eagle Artist Name: Janet Jackson Song Length (in seconds): 197 5. Unique ID: SD567 Song Name: I Got The News Artist Name: Steely Dan Song Length (in seconds): 306 (5) Implement the \"Add song\" menu item. New additions are added to the end of the list. (2 pts) Ex: ADD SONG Enter song\'s unique ID: SD123 Enter song\'s name: Peg Enter artist\'s name: Steely Dan Enter song\'s length (in seconds): 237 (6) Implement the \"Remove song\" function. Prompt the user for the unique ID of the song to be removed.(4 pts) Ex: REMOVE SONG Enter song\'s unique ID: JJ234 \"All For You\" remove.
