  • High data rate wireless communications links with transmission rates nearing 1 Gigabit/second (will quantify a “bit” shortly) Provide high speed links that still offer good Quality of Service (QoS) (will be quantified mathematically). Theoretically, the 1Gbps barrier can be achieved using this configuration if you are allowed to use much power and as much BW as you so please! Extensive research has been done on SISO under power and BW constraints. A combination a smart modulation, coding and multiplexing techniques have yielded good results but far from the 1Gbps barrier...

  • All solutions to engineering problems start with a calculation or estimation of the duty which must be met (i.e., quantifying the problem). The purpose of heating and cooling load calculations, then, is to quantify the heating and/or cooling loads in the space(s) to be conditioned. Rough estimates of load may be made during the concept design phase.

  • Two of the main distinctions between chemical engineers and other engineering disciplines are the topics of mass and energy balances. Within these two topics there are a lot of underlying chemical principles that help chemical engineers to perform calculations to determine what is happening in a system, allowing better control of a process.

  • Previous studies have shown that the Department of Defense (DoD) and the military departments have historically underestimated the cost of new weapon systems. Quantifying cost growth is important, but the larger issue is why cost growth occurs. To address that issue, this analysis uses data from Selected Acquisition

  • An algorithm for generating the possible quantifier scopings for a sentence, in order of preference, is outlined. The scoping assigned to a quantifier is determined by its interactions with other quantifiers, modals, negation, and certain syntacticconstituent boundaries. When a potential scoping is logically equivalent to another, the less preferred one is discarded. The relative scoping preferences of the individual quantifiers are not embedded in the algorithm, but are specified by a set of rules.

  • Performance evaluation measures the skill of an asset manager and its principal idea is to compare the returns with an alternative appropriate portfolio to that which was obtained in a particular case. The emergence of modern portfolio theory (MPT) by Markowitz (1952), who quantifies how rational investors make decisions based on expected return and risk, has brought much development to portfolio performance measurement.

  • Breath sounds have long been important indicators of respiratory health and disease. Acoustical monitoring of respiratory sounds has been used by researchers for various diagnostic purposes. A few decades ago, physicians relied on their hearing to detect any symptomatic signs in respiratory sounds of their patients. However, with the aid of computer technology and digital signal processing techniques in recent years, breath sound analysis has drawn much attention because of its diagnostic capabilities.

  • Introduction to shock & vibration gives an introduction to vibration through a description of the most common mechanical parameters leading to the behaviour of simple mass spring systems. Furthermore the different types of signals and their description is treated and the conversion between the different parameters is described mathematically and graphically. Finally the measurement units are defined.

  • Obtaining an accurate 24-hour-sleep-wake history is extremly important. History should be focused also on relevant factors as medical history, compensation of epilepsy, type and frequency of epileptic seizures, their incidence according to circadian cycle and actual antiepileptic medication, or other drug and medication use. Also social, enviromental or psychological conditions, which may interfere with sleep quality, should be evaluated. Neurological examination in connection with neuroimaging methods (MRI) can detect cerebral leasions as the reason of sleep problems.

  • Cells must be able to process multiple information in parallel and, more-over, they must also be able to combine this information in order to trigger the appropriate response. This is achieved by wiring signalling pathways such that they can interact with each other, a phenomenon often called crosstalk.

  • The Hybrid Artificial Intelligent model is a new method for evaluation of food biotechnology based on collaborative expert preferences and customer behaviours. This new approach using Kansei evaluation is to quantify expert sensibilities and emotions about bio-food quality in market and biofood research environments. Further improvement of food biotechnology evaluation applying for a real case study with expert feedbacks can be considered in future studies.

  • For most rural people in Cambodia, rice fi elds and associated habitats are important sources of fi sh and other aquatic animals (OAAs), which provide both nutrition and income. A lack of quantitative information contributes to a general neglect of rice fi eld fi sheries in development planning, which usually favours intensifi cation of rice production that may negatively impact the fi shery.

  • A mold’s productivity is ultimately measured by how many good parts it can produce over time. A mold that runs very fast but is frequently down for maintenance or repair will not produce at lowest part cost and highest productivity. Conversely, a mold that runs too slow but produces parts consistently over time is not optimal. The same can be said for each component in the injection molding system. One way to quantify productivity is to measure the total equipment productivity (TEP): TEP = Production hours (auto cycling) Parts made Scrap parts × × Available hours Hour Parts produced...

  • While such investigations yield differing effects dependent on the situation, the common observation of a temperature change has been associated with the presence of mechanical energy, which is required to overcome frictional resistance as sliding at the contact interface occurs. The energy, dissipated through conversion into thermal energy, is manifested as a temperature rise. At the microlevel, this increase can be substantial. A localized change in material properties, an enhancement in chemical reactivity, and ultimately, failure of the mechanical system can result.

  • The unearned premium reserve may have multiple roles under a deferral-matching accounting system. It may be viewed as a reflection of the refund liability in the event of policy cancellation10 . It may also be viewed as a way of deferring revenue so that revenue timing matches expense. These two views may result in different values, such as when a penalty would be charged the policyholder for early policy cancellation, although in practice such differences are generally ignored.
