Sramota me je što sam savremenik ove Amerike, njihovih podvala i laži, njihovih teorija zavjera, njihovih izmišljenih i virtuelnih neprijatelja protiv kojih se tobože mora angažovati 600 milijardi dolara svake godine (američki vojni budžet za ratove po Svijetu) kako bi se isti uklonili, a u stvari oni su generator većine ratova, sukoba i terorističkih napada našeg vremena
In 2002, we have installed a 60kw solar power generator at the rooftop of new head office building, which generated about 60,000kwh (CO2 emission reduction of about 25t-CO2) annually.
Wireless Ad hoc network is a set of wireless devices which move randomly and communicate with other node via radio signal. Ad-hoc networks may be logically represented as a set of clusters by grouping together nodes on the basis of different criteria such as 1-hop and k-hop that are in close boundary with one another. Clusters are formed by diffusing node identities along the wireless links. Different heuristics employ different policies to elect cluster heads. Several of these policies are biased in favour of some nodes. As a result, these nodes should greater responsibility and may deplete their energy faster, causing them to drop out of the network. Therefore, there is a need for load-balancing among cluster-heads to allow all nodes the opportunity to serve as a cluster-head. In this paper, different cluster head election mechanism are discussed in the one hop clustering approach.
This paper proposes a coordinated control of rotor side converters (RSCs) and grid side converters (GSCs) of variable speed doubly-fed induction generator (DFIG) based wind generation systems under unbalanced voltage conditions. The control scheme uses stator flux-oriented control for the rotor side converter and grid voltage vector control for the grid side converter. System behaviours and operations of the RSC and GSC under unbalanced voltage are illustrated. The cocoordinated control schemes manage to restore the wind turbines normal operation after the clearance of fault
This paper presents a novel low-cost, highly efficient, reliable and compact motor drive topology for residential and commercial application. The Brushless DC (BLDC) motor is a simple robust machine which has found application over a wide power and speed of ranges in different shapes and geometry. This paper briefly reviews the fundamentals behind the motor and also the different types of BLDC motors with different geometries and then presents a new configuration for BLDC motor/generator, which does not use a permanent magnet in the rotor. A new soft-switching boost converter is proposed in this paper. The conventional boost converter generates switching losses at turn ON and OFF,
1888PressRelease - This is a crowdfunding campaign which aims to assist an orphanage in Togo (West Africa) that is going through a serious housing issue. Our campaign aims to bring hope and stability to the lives of 58 children this holiday season, by building two dormitories and providing a power generator and clean water system. These seemingly simple things would be life changing for these children.

- Electrical discharge machining (EDM) is one of the most extensively disseminated manufacturing technologies, in particular as regards the generation of precise and difficult geometrical shapes on hard metallic components. The objective of this paper is to Study on Effect of Powder Mixed dielectric in EDM of Inconel 718. The effect of various powder mixed in dielectric is studied input parameters like Duty cycles, current, pulse on time and powder media in that Silicon carbide, Aluminium oxide, Graphite powder used. Machining characteristics measured in terms of Material removal rate, tool wear rate. To obtain the optimal process parameter combination, optimization is carried out by the Signal-to-Noise (S/N) ratio analysis of Taguchi method using L18 Orthogonal Array. An analysis of variance (ANOVA) is used to present the influence of process parameters on material removal rate, tool wear rate. Results obtained by Taguchi method and by ANOVA method, are compared
The hydraulic jaw crusher is a very popularly accepted, popular version of crushing stuff and it has been very popular in sectors include things likemetallurgy and mining, structure equipment, transportation and more just as well. The exploration industry is by and large regarded to possess the largest field post. Old jaw bone crushers more often than not consist of a structure, a fixed jaw bone, a movable jaw, toggle dishes as well as changeable seat pieces and which are usually all run by its generator and capable to efforts.
Ako se ubrzo ne okrene osnivanju nekog zajednickog tela sa Ruskim strucnjacima, I ako ne shvati potrebu za direktnim povezivanjem sa Ruskim institucijama -- ce dati signal da je partija nezainteresirana za kadrovsko-tehnicku pomoc, I da je samozadovoljna svojim na zapadu stecenim znanjem u raznim sferema drzavno-drustvenih-ekonomskih pitanja. Isto tako, ako se partija aktivno ne poveze sa strucnjacima za sigurnst izvan zapadnog sveta, nece biti dovoljno biti anti-NATO.
