The Port of Dover said sea conditions were rough on Friday and urged any passengers planning to use cross-Channel ferries to check with the operator before travelling.
end{cases} (5.2) It is easy to check that the operator (K_{sigma} ) is well defined and completely continuous.
It is easy to check that the operator T maps K ∩ ( Ω ¯ 2 ∖ Ω 1 ) into K.
It is easy to check that the operator A = − ∂ 2 ∂ x 2, D ( A ) = H 0 1 ( 0, π ) ∩ H 2 ( 0, π ) ⊂ H = L 2 ( 0, π ). is positive, self-adjoint with compact resolvent (A is diagonalizable).
It is easy to check that the operator A= -frac{partial^{2}}{partial x^{2}},qquad mathcal {D}(A)=H_{0}^{1}(0, pi cap H^{2}(0,pissubset H=L^{2}(0,positivepositive, self-adjoint with compact resolvent (A is diagonalizable).
It is easy to check that the operator A is increasing on P. On the other hand, A u ) ( t ) = ∫ ε T G ( t, s ) f ( s, τ u ( s ) ) d s ≥ φ ∫ ε T G ( t, s ) f ( s, u ( s ) ) d s = φ A u ( t ). for all λ ∈ [ ε, T ] and u ∈ P. Thus, the operator A is τ-φ-concave.
In the past, drivers M Check if the operator is a member of any industry bodies or groups.
To check the efficiency of these operators, a comparison is undertaken between these operators and partially mapped crossover (PMX) which is the common operator for sequential problem like TSP and VRP. Figure 6 illustrates this comparison.
However, alarms from objects that posed no immediate danger were common, supporting the assertion that sensor-based systems for proximity warning should be used in combination with other devices, such as cameras, that would allow the operator to check the source of any alarm.
Twice an hour, 48 times a day, a technician with a tape measure gauges the water level at the water intake building, and other operators check the level recorded by the Army Corps of Engineers four miles upstream, in Brownville.
