  • If natural language understanding systems are ever to cope with the full range of English language forms, their designers will have to incorporate a number of features of the spoken vernacular language. This communication discusses such features as non-standard grammatical rules, hesitations and false starts due to self-correction, systematic errors due to mismatches between the grammar and sentence generator, and uncorrected true errors.

  • Ambiguous keyboards provide efficient typing with low motor demands. In our project l concerning the development of a communication aid, we emphasize adaptation with respect to the sensory input. At the same time, we wish to impose individualized language models on the text determination process. UKO–II is an open architecture based on the Emacs text editor with a server/client interface for adaptive language models. Not only the group of motor impaired people but also users of watch–sized devices can profit from this ambiguous typing. ...

  • Most input/output devices reside the computer case. These devices communicate with what is inside the computer case through cables attached to the case at a connection called a port, sending data and/or instructions to the computer and receiving them from the computer. Most computers have their ports located on the back of the case, but some models put the ports on the front of the case for easy access. The most popular input devices are a keyboard and a mouse, and the most popular output devices are a monitor and a printer. The keyboard is the primary input devices of a computer.

  • 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...

  • Power electronics is the technology of processing and controlling the flow of electric energy by supplying voltages and currents in a form that is optimally suited to the end-user’s requirements [1].Atypical block diagram is given in Figure 1.1 [2]. The input power can be either AC and DC sources. A general example is one in which the AC input power is from the electric utility. The output power to the load can be either AC and DC voltages. The power processor in the block diagram is usually called a converter. Conversion technologies are used to construct converters.

  • This book examines the most recent advances in theory and research on communicative grammar instruction and the various instructional options for implementing it effectively in second language (L2) classrooms. A consideration of L2 teaching over the past few decades reveals a fundamental shift in the teaching of grammar from one in which grammar instruction was central, to one in which grammar instruction was absent, and to the recent reconsideration of the significance of the role of grammar instruction....

  • Headway is a key input in calculating the overall route capacity of any transit system. A system that requires large headways has more empty space than passenger capacity, which lowers the total number of passengers or cargo quantity being transported for a given length of line (railroad or highway, for instance). In this case, the capacity has to be improved through the use of larger vehicles. On the other end of the scale, a system with short headways, like cars on a freeway, can offer very large capacities even though the vehicles carry few passengers....

The timing error detector output signal enters a linear time-invariant loop filter. Its frequency responsein the Laplace domain is denotedby F(s) ; the frequencyresponsein the frequency domain is F(w).

  • Empirical evidence regarding international relative prices at the consumer level suggests that arbitrage in international markets is not rapid and that these markets are highly segmented. In fact, even markets for traded goods appear to be highly segmented internationally: In the data, both real exchange rate movements and deviations from the law of one price for traded goods are large and persistent.

  • Optical Transmitters The role of the optical transmitter is to convert an electrical input signal into the corresponding optical signal and then launch it into the optical fiber serving as a communication channel. The major component of optical transmitters is an optical source. Fiber-optic communication systems often use semiconductor optical sources such as light-emitting diodes (LEDs) and semiconductor lasers because of several inherent advantages offered by them.

While control theory research spans many decades and draws on several rich traditions, theoretical limitations have kept it from generating consistent and interpretable empirical findings and from reaching consensus concerning the nature of key relationships.

  • This is an arrangement more commonly adopted for complex building construc- tions rather than for civil engineering works. Under it the promoter appoints one contractor to manage all the construction inputs by letting contracts him- self. These ‘works contracts’ are effectively sub-contracts to the management contractor. Many may be labour-only contracts, while others are for ‘supply and erect’. The promoter may retain rights to approve or disapprove appointment of a works contractor.

  • The word technology refers to the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, and methods of organization, in order to solve a problem, improve a preexisting solution to a problem, achieve a goal, handle an applied input/output relation or perform a specific function. It can also refer to the collection of such tools, including machinery, modifications, arrangements and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments.
