Climate Change Global Warming - 1509 Words

One of the biggest problems the world is facing today is climate change. Climate change in the world can be caused by numerous activities including human activities. Climate change occurs when the temperature rises significantly, which leads to many different changes happening on Earth such less snow in the winter. These changes include floods, drought, or intense rain, as well as severe heat waves. One of the biggest problems is rising sea level, other cases are melting of glaciers, heating, and acidity of oceans. The earth’s climate changed plural times in the past due to natural causes but the current climate is different because human activities are the main cause. Ever since the Industrial Revolution humans have been releasing more and more carbon dioxide, which is accumulated in the atmosphere, this leads to the creation of the greenhouse, this disrupts our Earth’s climate. The greenhouse effect is when the energy from the sun drives the earth’s weather and climate and heats the earth’s surface, in turn the earth will radiate that energy back into earth which will cause a rise in temperature on earth because the gasses retain some of the outgoing energy trapping heat. Greenhouses gasses are carbon dioxide, methane, nitrox oxide water vapor and other gasses. These gasses originate from burning fossils which explain their capacity to produce energy. At first greenhouse effect was considered as a positive aspect but when greenhouse gases increase,Show MoreRelated Global Warming And Climate Change974 Words   |  4 Pagesabout global warming, whether it is true or false.

Analysis Of Toni Morrison s Sula - 1631 Words

Halloween, for many, is the best time of year. For some, it’s because of the free candy. But for people like me, it’s the power to express my creative, childhood imaginations and morph into any character for a day. But why can’t I become someone else forever, especially if it would make me happier? For Sula Peace and Nel Wright, in Sula, defining oneself in a pool of racism and varying moral standards is by no means challenging. Through a vivid and consistent emphasis of color and physical appearance, author Toni Morrison effectively outlines Sula and Nel’s attempts to comprehend and create their personal identities separate from the own mothers’ influences. Based on their situations, it appears that anyone can easily alter their character and self to fit their desires. However, Morrison ultimately emphasizes that one does not have complete control over their identity because of overwhelming familial and sociological barriers. Morrison makes it clear that a person’s skin color is an inherent and meaningful quality of their identity. One’s identity is composed of a combination of race, gender, ethnicity, family influence, and several other characteristics. Skin color can allows one to share similarities with those who are the same. Sula and Nel are both colored, and each understands that they are â€Å"neither white nor male† (52). Focusing on this similarity of color and gender is what draws them closer as friends, providing them with â€Å"ease and comfort† and an â€Å"intimacy† (52)Show MoreRelatedAnalysis Of Toni Morrison s Sula1655 Words   |  7 Pagesthe two girls share as a result of their juvenescence--or does it?

Computer Architecture and Organisation The Development

Question: Discuss about a Research Proposal for Computer Architecture and Organisation in The Development ? Answer: Introduction The accumulation recollection of a central processing unit represents the memory which can be readily accessed if required. The cache memory provides faster relay functions compared to the RAM. The cache memory is highly integrated into the CPU and is called upon when needed. The cache memory has many bus connections plugged to perform smoothly on the system. The question provides us with the main memory consisting of 16 bit memory address. The capacity for the memory that the 16 bit memory address provides = 216 = 65536 bytes of memory. Initially the memory is 65536 bytes and with the size of cache catch up variations like 64,128,256 bytes. In the next step we go through the words installed in every block of the cache memory and are varied like 1, 2 and 4 (Stallings, 2000). So we know that per block of cache memory may tag in 1 word, 2 words, or 4 words. Then the cache and the words contained in it vary like 16, 32 and 256 respectively per block. In the third step we are provided with the conjunctures to divide main memory and arrange it accordingly to direct mapping, we are provided with full associative of the memory (i.e. 2, 4 and 8) and then a second set of associates which gives a total of five. The division of the memory address takes place with the help of N set of associates. Overview of the simulation model The simulation model which we are concerned about deals with the cache memory that can work on different memory address, can work independent of different word per block and also different cache size. The concerned simulation model then deals with 17 cases of different memory address and other parameters of different cache organizations. The main memory address takes in variations like (1, 2, 4, 8 and 16) setting up associative mapping which calls out for 16 bit memory byte address to as 65536 bytes, 32768 bytes, 16384 bytes, 8192 bytes, 4096 bytes respectively for each block. In the second case the words per block of the cache in variations according to 1/2/4 words per block. Each word would consist of 4 bytes. And the result will be like 4 bytes, 8 bytes, 16 bytes for 1 word, 2 words and 4 words respectively for per cache block. The thirds case deals with the size of the cache which is varied from 64 byte, 128 byte, 256 byte which means that the cache lines can be terminated from this (Blanchet and Dupouy, 2013). 64 bytes of cache resulting in 26 bytes which represents 6 cache lines, 128 bytes of cache resulting in 27 bytes which represents 7 cache lines as well as it is for 256 bytes cache size which sums up to 28 bytes which portrays 8 cache lines. Simulation code: #include #include #include #define stream 1 //0 to print screen, 1 to write cache.txt #define main_memory 65536 //65536, 32768, 16384, 8192, 4096 addressable memory (1, 2, 4, //8, 16 way set associativity respectively) #define cache_line 64 //M can be 64, 128, 256 bytes that means // 26,27,28 bytes which says 6,7,8 cache lines respectively #define cache_block_size 1 //N can be 1/2/4 word in each cache line int cache_tag[cache_line]; //cache tag //if(cache_tag(i)==0, its=MISS) int total_memory_access=0; //amount of memory access or //address request from CPU int total_hit=0; //amount of cache hit //print the hit ratio void print_hit_ratio(void) { float ratio; if (total_hit==0) ratio=0; else ratio=(float)total_hit/(float)total_memory_access; } //reading input file line by line void input() { int ifp=0, address_requested; while(fscanf(ifp,"hdn",address_requested !-EOP) { int done=0; for(i=0;icache_line;i++) { if(address_requested=cache_tag[1] (address_requested=cache_tag[1]cache_bloc_size) { total_hit++; done=1; break; } } if (done==0) { lastwrote=(++lastwrote)%cache_line; cache_tag(lastwrote)=address_requested; } total_memory_access++; } } //print the content of cache table write_cache_table() { int i; int j; FILE *ofp; /output file pointer if(stream) ofp=fopen(cache.out,"w"); else ofp=stdout; //print table header fprintf(ofp,%d),"Lines"); for(i=0;icache_block_size;i++) { fprintf(ofp,"%6d",i); } fprintf(ofp "n" ); for(i=1;icache_block_size;i++) { fprintf(ofp,"---------"); } fprintf(of,"n"); //loop with cache line for(i=0;icache_line;i++) { fprintf(ofp,"%6d",i); } for(j=0;jcache_block_size;j++) { //no content in cache if(cache_tag[i]==0); { fprint(ofp,"%6d",0); else frintf(ofp, "%6f",cache_tag[i]=j); } fprintf(ofp,"n"); } fclose(ofp); } int usage(void) { printf("Please pass a field n"); printf("Usage: caches in n"); } int main(int argo, char *argv[]) { FILE *ifp; //input file int address_requested=0; //address sequential clrscr(); if (argo!= 2) { exit(usage()); } //read input file from command line ifp=fopen(argv[i], "r"); if(ifp==NULL) { printf("ERROR File does not exist :n ".argv[i]); exit(usage()); } print_hit_ratio(); input(); write_cache_table(); fclose(ifp); getch(); } Conclusion The conclusion gained from the topic is that the cache memory can be varied according to the set of associative created; the size of the cache can be varied according to the number of words. For a mock result we represent a cache of 64 bytes with 1/2/4 word block can have 16/8/4 words respectively in cache size. In the second case when the memory of the cache has capacity of 128 bytes with 1/2/4 word block then it can have 32/16/8 words respectively in memory. The last phenomena if the concerned cache memory has got 256 bytes with 1/2/4 words per block then it should consist of 64/32/16 words. References Baron, R. and Higbie, L.

Michelle Tomenchok Essays - Health, Obesity, Personal Life

Michelle Tomenchok Robin Mako Citarella English I How Food Addiction Causes Obesity More Americans become obese every year, with almost two thirds of the current US population today considered obese. But Why? Michael Moss explores in his essay "The Extraordinary Science of Addictive Junk Food" how corporations are altering the food we eat in an effort to get more market share. This altering or processing of foods had made them more addictive. Moss examines how the corporations use that addiction to their advantage, however Moss fails to touch on why this processing works. We will explore how these processed foods affect the human body by looking at environmental factors, the learned response or addiction to foods, the emotional state of eating and finally how obesity prevents weight loss. In order to understand how the human body is affected by processed foods we must first examine how environmental factors can affect our eating habits. The issue of environmental influences is important because we must understand how the world around us affects our food choices. Moss touches on the most basic environmental factor associated with food consumption , the advertising used by large corporations. Advertising and marketing is a well-studied field and is used to target specific audiences to purchase products . What was not explored however, is when this advertising is used to target young children. Just watch any Saturday morning cartoon and you will be inundated with commercials for high sugar cereals marketed by cartoon characters touting how great the cereal is or how cool you will be by eating it. Pomeranz explores this adverting to children in depth in "Television Food Marketing To Children Revisited: The Federal Trade Com mission Has The Constitutional And Statutory Authority To Regulate ." Her research shows that children exposed to advertising eat more of these foods than children who have not been exposed to such advertising. In describing her research she state, " Because the vast majority of food marketed to children is unhealthy, the net effect is that children are developing poor nutrition-related beliefs and behaviors as a result of their exposure to such communication" (Pomeranz, 99). This is important because young children under the age of 12 or 13 are most vulnerable to this advertising . She further explains that , "Marketing practices directed at a vulnerable population creates the condition that the intended listener is being misled. Since studies show that young children cannot comprehend the persuasive intent of marketing' and tend to accept commercial claims and appeals as truthful and accurate" (Pomeranz, 03). This quote helps to understand how adverting inf luences the food choices being made by young children . Advertising is only one factor in the environment that affects our purchasing of processed foods and in turn becoming more obese. Americans are only exposed to such adverting because of the changes in modern life. David R Seamon, a professor at the National University of Health Sciences , studied how weight gain is a consequence of living that modern lifestyle . I describing this research he said, "the modern lifestyle is associated with several behavioral factors that facilitate weight gain, such as eating too quickly, a lack of sleep, high stress levels and a lack of physical activity" (Seaman, 28). This is important because these factors alter the metabolism. When looking at stress specifically, historically, high stress levels in early humans signaled danger . When in danger humans fled that danger and in turn burned more calories. In modern times, these calories are no longer being burned off and are instead being retained and causing weight gain. A recent article written by two PhD's, Michael A Pizzi and Kerryellen Vroman also explored obesity in children and found that " factors such as domestic violence within a family or high stress due to chronic illness of a parent or guardian can result in children feeling they have little or no control. In order to suppress fear, concern, worry and anxiety the child may overeat" (105). This helps support the position that stresses in the environment from our family life or our work lives affect our eating habits and promote obesity. In addition to environmental factors, the learned response or addiction to certain
