Smart cities face vital waste management challenges regarding efficiency and sustainability in their development period. The established waste collection approaches that depend on pre-set schedules together with unchanging routes create problems by possessing both inefficient resource usage and elevated fuel usage as well as delayed waste pickup times. The proposed framework builds a Deep Reinforcement Learning (DRL)-based system for dynamic waste collection route optimization using Autonomous Waste Collection Vehicles (AWCVs) with Internet of Things (IoT)-based smart bins. The system uses Deep Q-Networks (DQNs) to analyze traffic conditions data alongside vehicle battery level data with smart bin information from the system so vehicles carry out efficient waste collection operations using minimal energy. The newly proposed algorithm provides 30% distance reduction and 28% faster responses and 30% lower energy usage than baseline heuristic methods do. The conclusions show that AI-powered waste management strategies can create sustainable operations which increase both service performance and overall energy efficiency in cities. The research team plans to apply the proposed approach to actual waste collection systems while exploring methods of deploying multiple agents alongside renewable energy systems to enhance future urban waste management operations.

It is concluded from the results of testing the frequency characteristics of the sub micron precision machine tool servo control system, that the existence of several oscillating modalities is the main factor that affects the performance of the control system. To compensate for this effect,several concave filters are utilized in the system to improve the control accuracy. The feasibility of compensating for several oscillating modalities with a single concave filter is also studied. By applying a modified Butterworth concave filter to the practical system, the maximum stable state output error remains under ±10 nm in the closed loop positioning system.
control-flow dependence has always been posited as a substantial dilemma against program acceleration. With the availability of instruction-level parallel architectures, ifconversion optimization has become pivotal fo...

SUPER-HEAVY-LIFT ROCKETS: NASA is relying on the Space Launch System (SLS) for its 2024 lunar return plan—although the rocket is over budget and behind schedule. China is working to upgrade its current Long March 5 rocket (which failed in its second flight) to the Long March 9. Russia says it has finalized the design for its Yenisei rocket, but experts wonder if it will actually get built. Blue Origin and SpaceX's rockets use reusable stages, which could make them much more economical. SpaceX's Starship is the most futuristic of the lot, comprised of reusable stages and a built-in crew capsule.
In the Model Predictive control (MPC) framework a controller is computed using a finite horizon optimal control cost. When linear constraints are imposed on the system with a quadratic cost function, then the MPC prob...

Analyzed is natural transient convection followed by steady-state convection in an elliptical cavity heated from below, using a spectral finite difference scheme in terms of a Dim expansion. The major or minor axis of the elliptic section of the cavity is assumed to be placed horizontally. As a thermal boundary condition, Dirichlet or Neumann condition is specified. Not only for nearly pure-heat conduction case at low Grashof numbers but also for strong convection flow with cellular patterns at larger Grashof numbers are found to be attained at least for some combination of Prandtl numbers and geometrical parameters.
