Technology Making Our Lives Easier Essay Example for Free

Technology Making Our Lives Easier Essay As we are raised in a society where everything is simply handed to us, we tend to take many things for granted that others in the world do not have. Things like GPS, phones, credit cards, cameras, and insulin pumps help us live a qualitative and productive life and NASA has played a very key role in developing many technologies like these. From invisible braces to long-distance communication devices, NASA has brought up inventions that we consistently use every day in our lives. A device that many people in the world rely on everyday and something that has made a huge difference in peoples lives is the water filtration system(s). NASA first made it to be used on the space station or in a spacecraft, and since then the water filtration system is a must-have in any place in the world. NASA showed amazing ingenuity to control bacterial contamination in space, and because of that, we have learned how to control pollutants in water here on earth. We see water filtration systems more than we think, and it allows us to enjoy a healthy lifestyle. Whether its through swimming pools or manufacturing processes, the water filtration systems affects our lives every day in a positive way. There are many different types of water filters and you can classify them by the way they work, but they all need to do one job and thats effectively filter and purify water. One type of a water filtration system is the reverse osmosis, which is the process of removing dissolved inorganic solids out of a solution (water). This type of system involves using many different filters and membranes in order to purify and improve the drinking quality of water. There are also ultraviolet systems which do a remarkable job at disinfecting water. Ultraviolet systems can destroy 99. 99% of harmful microorganisms in the water very effectively and they do this by using a lamp or bulb which emits UV light which is then used as energy to attack the microorganism in the water and essentially destroy it, thus making the water free of future bacteria. There are many other type of systems like the Carefree Clearwater systems (which are based on NASAS late 1900s technology) which are not only used for drinking water in the home, but also for pool and shower water. These type of large-scale systems clean the water in a pool or hot-tub by using the same type of strategy as the UV systems. They release ions like copper and silver to destroy bacteria and algae in the system. These type of systems would work better than cleaning with chlorine because they have less nwanted side effects like burning eyes and bleached skin or hair (due to the copper and silver ions not dissipating from heat and sunlight, unlike chlorine) and they are more stable and productive to work with. Water filtration systems affect our lives everyday throughout everything we do. Without them, clean and purified water would be difficult to come across, and civilization would eventually come to a halt. Whether its the water that we drink or the pool that we love to sw im in, systems like the reverse osmosis and the Carefree Clearwater are at work and doing an incredible job in order to make our daily lives healthy and enjoyable.

Essay on The Yellow Wallpaper, A Rose for Emily and Babylon :: Yellow Wallpaper essays

The Yellow Wallpaper, A Rose for Emily and Babylon It is amazing how differently people see the world. People from different walks of life interpret everyday experiences in different ways. This is ever so apparent when discussing the gaps that occur in stories by great authors. In The Yellow Wallpaper, a woman is being "treated" by a doctor (her husband) for a condition he refers to as anxiety. She is placed in a room, apparently one that was previously inhabited by a mental patient, and told to rest. Over the course of a few weeks the woman begins to exhibit signs of paranoia and regularly has hallucinations. Through the course of the story, the woman continuously makes reference to the yellow wallpaper. The first, and possibly the greatest, gap in the story comes when interpreting the meaning(s) behind the wallpaper. Does the color yellow infer something about insanity? The woman repeatedly refers to the patterns that the peeling wallpaper makes. Do the patterns suggest order from chaos? It is apparent, from the number of times that it is mentioned, that the wallpaper plays a role in the mental changes the woman experiences (and details her changes) throughout the story. Part way through the story, she begins seeing a woman moving behind the wallpaper, as if trying to escape it. Is she actually seeing herself in the wallpaper, as suggested by Chris Tildon, or is the hallucination what she fears she is becoming? At the end of the story, she takes on the role of the "creeping" woman and follows a smudge around the room and over her fainted husband. This supports the idea that she is the woman that has been trapped in the paper. Maybe she feels trapped and tormented by John's lack of sympathy for her condition. Another story that benefits from gaps is Babylon Revisited by F. Scott Fitzgerald. The gaps in this story are numerous, but the most important gaps involve Charlie's previous bout with Alcoholism, and his struggle to retrieve his daughter Honoria. Charlie claims to be a reformed man. However, after reading deep into the story, it is apparent that Charlie plays a role in his own downfall. Does Charlie actually try to rid himself of his past, or is he actually perpetuating it? In the story, Charlie visits his old "haunts", maintains a "one drink a day" attitude, and inadvertently brushes elbows with a couple of old drinking buddies.

Sap Bw Parallel Data Load

Scenario You have an SAP BW system with several (application) servers. You would like to distribute the workload of the data loads and other data warehouse management activities in a way that fits your needs best. This could mean that you would like to have all processes distributed across all available servers or that you would like to have one dedicated server for these processes. 2 Introduction SAP uses the terms instance and application server synonymously. In order to avoid misunderstandings we use the term instance for an SAP instance (application server) in this document.For a physical machine we use the term server. Some of the settings described in this document are done on an instance level, some on a server level. If you don’t have several instances (of the same SAP system) on one server you don’t have to draw this distinction between instance and server when reading this document. There are a host of functions and settings in the area of load balancing provi ded by the basis system (Web Application Server). However, these have been designed primarily for SAP’s ERP system.Customizing these features for optimal use with SAP BW requires further considerations. The challenges presented with data load processing originate from the fact that many fairly long running processes can be started almost simultanesouly. The standard SAP load balancing approach takes the quality of the instances into consideration when distributing the load. This quality is evaluated in regular intervals (five minutes by default). Within one interval a lot of parallel processes may be started on the best instance, using a lot of work processes while the other instances are idle.An optimal distribution of BW OLAP workload or data load resource consumption cannot readily be achieved with this standard method. Without adequate planning, and under heavy workload (peak) conditions, the risks can increase that hardware becomes a bottleneck; a limited number of serve rs can become saturated with processes consuming resources, and performance (and stability) can potentially suffer significantly. A successful load balancing approach optimally utilizes the hardware resources that have been allocated to the BW system.Note that this discussion assumes that an adequate sizing has been performed to properly size the SAP BW system (see SAP Service Marketplace alias â€Å"quicksizer† for more information). This document describes load balancing approaches for typical SAP BW activities. Commonly these activities process large amounts of data. Data (within one process) is split into packages and can thus be processed in parallel on one or across several servers or instances. On the other hand, several processes can run in parallel on one or on several servers or instances.This means that we can have parallel processing (and consequently achieve load balancing) both within one process and across processes. In our examples we will use a system called XXX as SAP BW system and a system called YYY as an SAP source system of XXX. During data load processing, data is extracted from the source system and sent to the target SAP BW system. Other load processes involve the SAP BW system as source system, as well as the target system (for example, DataMarts, activation of data in ODS objects). The instances and servers on XXX are as follows, the server ab1234 being the database server:
