Simple circuit performs binary addition and subtraction

Ripple adder reduces the number of logic circuits required to preform binary addition and subtraction. The adder uses dual input and delayed output flip-flops in one register. The contents of this register are summed with those of a standard register through conventional AND/gates

Meanings in the Process of Signification of Lancôme's Beauty Serum Advertisements

Through this study, the writer aimed to find out how meanings are created in advertisements video. The three objectives of this study are to find out how meanings are created through verbal expressions, how the visual expressions of the advertisements support the verbal expressions and to find out the differences between the two advertisements. The data used to conduct this study were Lancôme Génifique Serum Advertisement (2009) and Lancôme Advanced Génifique Serum (2013). After analyzing the data with the research questions in mind, the writer found out that meanings in both advertisements are created through the verbal captions and what were visually shown on the advertisement videos. The writer also found out that there were a few differences between the first and second advertisements. The second advertisement provides more appealing visuals, more direct and convincing verbal expressions and more facts and needed information regarding the promoted product. These factors make the second advertisement an improved version of the first one

Energy management of three-dimensional minimum-time intercept

A real-time computer algorithm to control and optimize aircraft flight profiles is described and applied to a three-dimensional minimum-time intercept mission

An on-board near-optimal climb-dash energy management

On-board real time flight control is studied in order to develop algorithms which are simple enough to be used in practice, for a variety of missions involving three dimensional flight. The intercept mission in symmetric flight is emphasized. Extensive computation is required on the ground prior to the mission but the ensuing on-board exploitation is extremely simple. The scheme takes advantage of the boundary layer structure common in singular perturbations, arising with the multiple time scales appropriate to aircraft dynamics. Energy modelling of aircraft is used as the starting point for the analysis. In the symmetric case, a nominal path is generated which fairs into the dash or cruise state. Feedback coefficients are found as functions of the remaining energy to go (dash energy less current energy) along the nominal path

Optimal symmetric flight with an intermediate vehicle model

Optimal flight in the vertical plane with a vehicle model intermediate in complexity between the point-mass and energy models is studied. Flight-path angle takes on the role of a control variable. Range-open problems feature subarcs of vertical flight and singular subarcs. The class of altitude-speed-range-time optimization problems with fuel expenditure unspecified is investigated and some interesting phenomena uncovered. The maximum-lift-to-drag glide appears as part of the family, final-time-open, with appropriate initial and terminal transient exceeding level-flight drag, some members exhibiting oscillations. Oscillatory paths generally fail the Jacobi test for durations exceeding a period and furnish a minimum only for short-duration problems

Measurement of the B_s^0→K^+K^- lifetime relative to the B_d^0→K^+π^- lifetime

The study of B decays to charmless charged hadrons offers an opportunity to improve our understanding CP violation and to search for New Physics beyond the Standard Model. We present an analysis to make a measurement of the B_s^0→K^+K^- lifetime relative to B_d^0 lifetime which removes systematic bias introduced to the lifetime by distance of flight based selections
