overlapping BSS (Basic Service Set) where BSS (i.e. WLAN cells) is fundamental block of IEEE 802.11 WLAN architecture. OBSS occurs due to two or more unrelated BSSs are used at the same place, at the same time and with the same frequency channel. With the expansion of channel bandwidth to 80 MHz (may be, 160 MHz) in upcoming standards, the OBSS problem is likely to be very severe in the future. This paper examines how OBSS can be harmful to the networks and how it can be avoided using beam forming, distributed
supported by the increasing demand for augmented capacity, data rates, and data services due to: The tremendous momentum in wireless technology created both by the successful deployment of second generation mobile systems, e.g., GSM (including the quest for cheaper, smaller ... ... middle of paper ... ...e, especially in rich-scattering environments. This has been shown for wireless communication links in both narrowband channels as well as wideband channels, and it initiated a lot of research activity
increases the capacity of the wireless channel.Capacity is expressed as the maximum achievable data rate for an arbitrarily low probabilityof error. Thistechnology received a fillip when TarokhEtA introduced their space-timetrellis coding techniques and Alamouti introduced his space-time block codingtechniques to improve link-level performance based on diversity. Another boost came in form of BLAST Technology. But in this paper, our focus will lie basically on the MIMO wireless channel and how to determine
consideration of planning future network capacity is determining what services, users, and data will be present on the network. Take the time to complete a thorough site analysis. A bit of formal analysis now will ease the process of upgrading and configuring the system later. Don't succumb to the "easy way out." Planning can be a long and arduous task that is overlooked far too often, but one that pays off ultimately. Network Capacity Analysis The capacity of a network is that network's ability
the production plan would be derived. Step 3- Rough-cut capacity planning; it involves short-term capacity considerations that are affected by irregularities in demand. It formulates benchmarks for the proper use of personnel, machines, and shifts. Bills of capacity and bills of labour resources are the primary inputs to determine rough-cut capacity. In the event of incapability in producing the require output (due to limitation of capacity), adjustment to the production plan would be made. Step
Anemia I. Introduction Iron Deficiency Anemia affects millions of individuals across the world. This disease strikes many more women than men and has harmful effects on all who suffer from this deficiency that causes oxygen-carrying capacity to decrease. The causes can vary amongst different groups, but the aggravating symptoms remain constant. Much of the research on Iron Deficiency Anemia concentrates on not only the treatment of this disease, but also the prevention of it. To attain
She uses the following argument schemas to set out the 'logic of domination'. A1. Humans do, and plants and rocks do not, have the capacity to consciously and radically change the community in which they live. A2. Whatever has the capacity to consciously and radically change the community in which it lives is morally superior to whatever lacks this capacity. A3. Thus, humans are morally superior to plants and rocks. A4. For any X and Y, if X is morally superior to Y, then X is morally
posits language as a medium of communication that is capable of safeguarding the development of subjectivity and freedom. Language does this in a twofold manner: on the one hand, it is an action that does not phenomenally alter being, but that has the capacity of altering consciousness; on the other hand, language, more particularly written text, is a mode of communication that is delayed, hence that occurs outside the present, i.e. in a different space and a deferred time. As such, it preserves the subjectivity
The first things we learned in EGEE I thought I already knew, but I only had superficial knowledge about such things energy, heat, and radiation. For example, I thought that energy was simply the ability to work. However I learned that it is the capacity to do work (Kraushaar and Ristinen 8), generating heat, and emitting radiation (lecture 1/9/02). I also learned that the formula for energy is work = force x distance (1/9/02). Heat, we learned, is the ability to change the temperature or phase
and their answers varied greatly. One described intelligence as “equivalent to the capacity to learn.” Other definitions included “the ability to adapt adequately to relatively new situations”, “the capacity to learn or profit from experience”, and “the knowledge that an individual possesses.” And one stated that there was no simple definition to the word because “intelligence involves two factors- the capacity for knowledge and knowledge possessed” (Sternberg & Detterman, 1986, p.39-40). Dictionaries
one of the many lessons found within Genesis 2.0 and more specifically the story of Adam and Eve. It is also from this twisted tale of betrayal and deceit that we gain our knowledge of mankind?s free will, and God?s intentions regarding this human capacity. There is one school of thought which believes that life is mapped out with no regard for individual choice while contrary belief tells us that mankind is capable of free will and therefore has control over hisown life and the consequences of his
from those with. His criteria are the entity must have the capacity for speech and act from knowledge. His justifications that machines do not meet these two criteria are sound; however, he fails to verify that animals do the same. Descartes’ argument that humans have an infinite capacity to make appropriate responses is true as well as his implication that this capacity is non-material. Descartes’ first argument is only humans have the capacity for speech. In the opening of Discourse on Method Descartes
of mul, which in this case would be 10*10. The result is then implicitly stored in EDX:EAX. The result is stored over a span of two registers because it has the potential to be considerably larger than the previous value, possibly exceeding the capacity of a single register(this is also how floating points are stored in some cases, as an interesting sidenote). So, now comes the ever-important question. How can we use these attributes to our advantage when writing shellcode? Well, let's think
cleavage, where the cleavage planes are either parallel or perpendicular to the vertical axis of the egg. Deuterostomes are further characterized by indeterminate cleavage, which means that each cell produced by early cleavage divisions retains the capacity to develop into a complete embryo. Indeterminate cleavage of the human zygote allows identical twins to be possible. In a protostome, as the archenteron forms, solid masses of mesoderm split to form the coelomic cavities, or schizocoelous development
Squire. Richard turned his passion for brewing good home made beer into a lucrative business. In 1989, he started his first Breckenridge Brewery and Pub at Breckenridge which has a production capacity of 3,000 barrels per year. During his first two years in business, he sold out the brewery's annual maximum capacity. He opened a second brewery and brew pub in Denver in November 1992. By the end of 1994, even this brewery failed to satisfy the increased demand and plans were made for a new brewery which
defined as a “blank slate.” Locke believed that everyone is born with a clean mind, a supposed condition that he attributed to the human mind before ideas have been imprinted on it by the reaction of the senses to the exterior world. “Thus the first capacity of human intellect is that the mind is fitted to receive the impressions made on it; either through the senses by outward objects; or by its own operations when it reflects on them. This is the first step a man makes towards the discovery
for surgery. In such major life changes, the sources of the emotional response is much more easily identified (Shapiro MacFarlane Hussain 49). There are two types of stress: bad stress or negative stress which destroys your ability to operate at capacity, mentally and physically and good stress which improves your performance (Shapiro 49-50). There are different ways to reduce stress. One should try to find a job he really enjoys. It is not the stress of work that wears one out but the stress of
defined as “a set of rules which define what is right and wrong.” (Outka and Reeder, p.5) Who decides what is right and wrong often depends, as with Thucydides’ history, on who has the power in a given situation. Power can broadly be defined, as the capacity to achieve what one wants. (Dickerson and Flanagan, p.24) In the case of these two debates, the Athenians were the party who possessed the power. They had the coercive ability to decide the fates of both the Melians and the Mytilenians. This power
Alexander Pope's Essay on Man - Man is Never Satisfied Alexander Pope's Essay on Man is a philosophical poem, written, characteristically in heroic couplet. It is an attempt to justify and vindicate the ways of God to man. It’s also a warning that man himself is not as in his pride, he seems to believe the center of all things. Eventhough not truly Christian, the essay makes implicit assumption that man has fallen and that he must seek his own salvation. Pope sets out to demonstrate that
comprehension. I think the best system of obtain consent would incorporate a regulated system that accommodated each institution and their requirements, but also equally weighed the importance of true understanding of facts and realization of the patient’s capacity to make decisions. But even if this was established as standard practice, there would still be the issue of how the assessment is made and how accurate it is due to other influences i.e. current injury status or medications needed for full psychological
