NCS Model and Problem Statement Sample Clauses

NCS Model and Problem Statement. In the following we describe a NCS that includes unknown time-varying sampling intervals and un- known time-varying delays. A schematic of the considered NCS is shown in Fig. 16. It consists of a linear continuous-time plant x˙(t) = Ax(t) + Bu(t) (138) ∈ ∈ with A Rnx×nx and B Rnx×nu , and a discrete-time controller, connected over a communication network that induces network delays, namely the sensor-to-controller delay τ sc and the controller-to- actuator delay τ ca. A complete measurement of the state vector x(t) is assumed to be available at the sampling time instants Σ i s = k—1 h 6k ≥ 1, s0 = 0, (139) ∈ which may not be equidistantly spaced in time due to the time-varying sampling intervals hk > 0. The sequence s0, s1, s2, . . . is assumed to be strictly increasing, i.e., sk+1 > sk, for all k N. We denote by xk = x(sk) the kth sampled value of the state x and by uk the corresponding control value. The zero-order-hold (ZOH) function in Fig. 16 transforms the discrete-time control input uk to the continuous-time control input u(t) applied to the plant.

  • Problem Statement School bus fleets are aging, and our communities have poor air quality. Replacing school buses with zero emission school buses will address both of these issues.

  • Problem Solving Employees and supervisors are encouraged to attempt to resolve on an informal basis, at the earliest opportunity, a problem that could lead to a grievance. If the matter is not resolved by informal discussion, or a problem-solving meeting does not occur, it may be settled in accordance with the grievance procedure. Unless mutually agreed between the Employer and the Union problem-solving discussions shall not extend the deadlines for filing a grievance. The Union Xxxxxxx or in their absence, the Local Union President, or Area Xxxxxxx, or Chief Xxxxxxx, either with the employee or alone, shall present to the appropriate supervisor a written request for a meeting. If the supervisor agrees to a problem- solving meeting, this meeting shall be held within fourteen (14) calendar days of receipt of the request. The supervisor, employee, Union Xxxxxxx, and up to one (1) other management person shall attempt to resolve the problem through direct and forthright communication. If another member of management is present that person will not be hearing the grievance at Step Two, should it progress to that Step. The employee, the Union Xxxxxxx or in their absence, the Local Union President, or Area Xxxxxxx, or Chief Xxxxxxx, may participate in problem-solving activities on paid time, in accordance with Article 31, Union Rights, Section 1H.

  • Construction Schedule The progress schedule of construction of the Project as provided by Developer and approved by District.

  • Completion Schedule 6.1 The proposed schedule for the completion of the Project is presented in “Attachment D” and is made a part hereof. 6.2 ENGINEER shall adhere to all time limits stated in this Agreement or included in any accepted time schedule. All such time limits shall be of the essence to this Agreement. 6.3 In all events the various stages and phases of ENGINEER’S services are to be completed in such sequence and at such times, and with approved or agreed upon time limits, as may be required to assure the timely, continuous, efficient and diligent prosecution of the work and services provided for by this Agreement. 6.4 OWNER may at any time, by written order, make changes within the general scope of the Agreement in the services of work to be performed. If ENGINEER believes that such a change justifies an increase in ENGINEER’S contract time or contract price required to perform the series under this Agreement it must assert such claim in writing within thirty (30) days of receipt of OWNER’S written order giving rise to the claim. No claim for adjustment in the contract time or contract price will be valid if not submitted in accordance with this paragraph. No services for which ENGINEER will charge additional compensation shall be furnished without the written authorization of OWNER. 6.5 ENGINEER shall carry on all work required under this Agreement and maintain the schedule for services during all disputes or disagreements with OWNER. No work shall be delayed or postponed pending resolution of any disputes or disagreements except as permitted in Article 8, or as ENGINEER and OWNER may otherwise agree in writing. 6.6 If the commencement, prosecution or completion of the services under this Agreement, or of the construction of the Project is delayed by any act, omission, delay, neglect or default of ENGINEER, or anyone employed by ENGINEER, or by any damage or acts caused by the negligent acts or omission by ENGINEER, then ENGINEER shall be liable to OWNER for any and all costs, assessments, expense, liabilities or damages caused thereby, in accordance with Section 4.8. 6.7 ENGINEER shall not be responsible for any time delays in the Project, or in the performance of services under this Agreement, to the extent such delays are caused solely by any act, omission, neglect or default of OWNER or anyone employed by OWNER, or by the unreasonable delay of any review agency or utility, or for any delay or damage caused by fire or the combined action of workers and which are in no way chargeable, in whole or in part, to ENGINEER, or by any other conditions or circumstances beyond the control of ENGINEER, its employee, agent, or other persons for whose acts or omissions ENGINEER is responsible. In the event of such delay, ENGINEER shall be entitled to an adjustment in the schedules or agreed time limitations for the performance of services, and this Agreement shall be modified in writing accordingly. Any claim of ENGINEER for adjustment under this cause must be asserted in writing within thirty (30) days from the date of the occurrence of the event giving rise to the claim, unless OWNER grants a further period of time before the date of final payment to ENGINEER. The adjustment of time for the performance of services, as provided in this paragraph, shall be ENGINEER’s sole exclusive right, entitlement and remedy in the event of such delays, and ENGINEER shall have no claim against OWNER for adjustment for increase in costs of performance, or other damages occurred in connection therewith.

  • Vacation Schedule 1. Vacation periods shall be fixed by the Employer to suit the requirements of his business, but as far as possible and practicable, vacations will be given during the summer months, and for employees with school-age children, during the school vacations. Vacation periods shall be unbroken unless by mutual consent between Employer and employee, or where it is impractical. Grievances relating to this Section shall be subject to the Adjustment and Arbitration Procedure in this Agreement. 2. Time off, based upon service in the Industry Vacation Plan, may be granted to an employee by mutual agreement between the Employer and the employee. The Employer shall not be required to give time off based upon service under the Industry Vacation Plan. However, if such additional industry vacation time off is granted to an employee, such time off shall be counted as time worked for the purpose of computing the employee's earned vacation benefits on his next anniversary date of employment.

  • Rent Rolls; Operating Histories The Seller has obtained a rent roll (the “Certified Rent Roll(s)”) other than with respect to hospitality properties certified by the related Mortgagor or the related guarantor(s) as accurate and complete in all material respects as of a date within 180 days of the date of origination of the related Mortgage Loan. The Seller has obtained operating histories (the “Certified Operating Histories”) with respect to each Mortgaged Property certified by the related Mortgagor or the related guarantor(s) as accurate and complete in all material respects as of a date within 180 days of the date of origination of the related Mortgage Loan. The Certified Operating Histories collectively report on operations for a period equal to (a) at least a continuous three-year period or (b) in the event the Mortgaged Property was owned, operated or constructed by the Mortgagor or an affiliate for less than three years then for such shorter period of time, it being understood that for mortgaged properties acquired with the proceeds of a Mortgage Loan, Certified Operating Histories may not have been available.

  • Vacation Scheduling a) Vacations may be requested at any time of the year, subject to the restrictions below. The supervisor, or designate, will grant requests subject to operational requirements and in accordance with such vacation quotas as the Employer may set from time to time. Employees shall be advised of vacation quotas one month prior to the employees being required to submit their requests. Such quotas will not be unreasonably restrictive. b) Requests for vacation time from the Monday immediately following June 20th to the Sunday immediately following Labour Day (summer period) shall be made in writing to the Employer not later than March 1st in that year. The Employer will respond to such requests in writing by April 1st. An employee may be approved for a maximum of three (3) weeks of vacation during these peak times. c) Requests for Christmas/New Year’s vacation time between the Monday immediately following December 15th and the Sunday immediately following January 1st shall be made in writing to the Manager or designate not later than August 1st in that year. The Employer will respond to such requests in writing by September 1st. An employee may be granted a maximum of one (1) calendar week (or part thereof) over this period. d) March Break vacation requests shall be submitted to the immediate Manager or designate not later than November 1st of the preceding year. The Employer shall respond in writing by December 1st. e) In the event that the number of employees in each department or team requesting vacation for or during any part of the above peak periods exceeds the number which the Employer has determined might be permitted vacation at that time, priority will be given based on seniority as per the posted seniority list. f) Notwithstanding e) above, in granting vacation requests during peak periods, the Employer will grant requests for full weeks of vacation prior to granting requests for partial weeks of vacation, so that a request for less than one week’s vacation cannot prevent another employee from taking a full week of vacation. A full week of vacation shall be defined as Monday through Sunday. g) Requests for vacation for other periods outside of peak times shall be submitted by the employee to their immediate supervisor not less than three (3) weeks prior to the first day of the vacation period.
