Cellulose fibers with porous structure and electrolyte absorption properties are considered to be a good potential substrate for the deposition of energy material for energy storage devices. Unlike traditional substrates, such as gold or stainless steel, paper prepared from cellulose fibers in this study not only functions as a substrate with large surface area but also acts as an interior elec...

Caruachi Hydroelectric Project conforms together with Guri, Tocoma and, Macagua the Lower Caroni Hydroelectric Development. Second Stage of River Diversion at Caruachi included diverting the Caroni River through 18, 5.5 × 9m sluices in the spillway lower body that after being closed by gates permitted the reservoir filling. In order to define the precise timing for closure of the sluices and to...

Most common methods used in optimal control of reservoir systems require a large number of control variables, which are typically the sequences of releases from all reservoirs and for all time steps of the control period. In contrast, the less widespread parameterization-simulation-optimization (PSO) method is a low-dimensional method. It uses a handful of control variables, which are parameter...

Theoretical description of excitation energy transfer in light-harvesting complexes, for example, in natural photosystems, is a complicated computational problem, though, in principle, it boils down merely to solution of time-dependent Schrodinger equation. To solve the equation one needs the information about the eigenstates and the initial state of the given system. While the second requireme...

We evaluate miniature batteries as potential power sources for advanced wildlife telemetry tags. These tags are often based on integrated UHF transceivers that are designed for wireless sensor networks and that consume 18-85mA while receiving or transmitting. This current drain is challenging for many types of miniature batteries. We evaluate batteries both on actual tags and in a specialized s...

This study aims to investigate the different management policies of multi-reservoir systems and their impact on the demand supply and hydropower generation in Great Karun River basin. For this purpose, the semi-distributed simulation-optimization  model of the Great Karun River basin is developed. Also, the multi-objective particle swarm optimization algorithm is applied to optimize the develop...

We investigate theoretically the linear conductance of a two-level quantum dot as a function of the gate voltage and different strength of coupling to the external electronic system (the reservoir). Apart from the weak coupling regime, characterized by the Kondo-enhancement of the conductance in the spin-ful ground state, a strong coupling regime, which can be called mixed-valence (MV), is foun...

Nanotechnology can be applied as a common-purpose technology, as it has important impacts on almost all industries and all areas of science. In those early days, scientists and engineers have confirmed their study on the development of nanomaterials and their applications in various fields. Nanoparticles have a wide range of applications, since it incorporate knowledge from the fields of Physic...
