This paper deals with a wind-based stand-alone generating unit with Permanent Magnet Synchronous Generator (PMSG) and a Lead Acid Battery (LAB) for energy storage, during wind speed variation as well as transient performance under variable load. The main purpose is to supply 230 V/50 Hz domestic appliances through a single-phase inverter. Simulations and experimental results validate the stabil...

We present a self-powered integrated microfluidic blood analysis system (SIMBAS) that does not require any external connections, tethers, or tubing to deliver and analyze a raw whole-blood sample. SIMBAS only requires the user to place a 5 μL droplet of whole-blood at the inlet port of the device, whereupon the stand-alone SIMBAS performs on-chip removal of red and white cells, without external...

This paper describes the architecture of OPERA, a generic platform for building distributed systems over stand alone applications. The main contribution of this research effort. is t,o propose a “kernel” system providing the “essentials” for distributed processing and to show the important role database technology may play in supporting such functionality. These include a powerful process manag...

– This paper investigates the application of the model predictive control (MPC) approach to control the voltage and frequency of a stand alone wind generation system. This scheme consists of a wind turbine which drives an induction generator feeding an isolated load. A static reactive power compensator (SVAR) is connected at the induction generator terminals to regulate the load voltage. The ro...

This article recounts the development of a stand-alone CAD platform, the IDIIOM. The IDIIOM was developed during the mid-1960s at Information Displays, Inc. (IDI), then in Mt. Vernon, N.Y. According to its creators, the IDIIOM was the first general-purpose design workstation, the first commercial CADD platform, and the first software drafting package to operate on its own computer without commu...

There are two fundamenta l issues that must be considered when purchas ing any standalone EPLI product. Preferably, these issues will be evaluated before the insurance broker goes to market and begins negotiating more specif ic cove rage terms. First, the policyholder should decide whether it wants a "working layer" program (i.e., a policy wi th re la t ive ly low l i m i t s c o m b i n e d w ...

A scrutiny of the existing time differencing carrier phase (TDCP) velocity estimation algorithms has revealed several shortcomings which could be further improved. One of those is that the velocity estimation at epoch t would require the receiver positions at epoch t+Δt or more are available. Another one is the usage of satellite velocities in the calculations which would increase the receiver ...

We present a new design for a compact stand-alone force and friction microscope. Both the force sensor and the scanning unit are mounted on the microscope head, thus allowing the investigation of virtually all surfaces, independent of thickness and size, and minimizing the geometrical dimension. The beam deflection method in a collinear arrangement is used to detect the normal force and the fri...

On remote islands photovoltaic (PV) panels with battery energy storage systems (BESSs) supply electric power to customers in parallel operation with engine generators (EGs) to reduce fuel consumption and environmental burden. A BESS operates in voltage control mode when it supplies power to loads alone, while it operates in current control mode when it supplies power to loads in parallel with t...

This paper presents a design for a stand-alone photovoltaic (PV) system to provide the required electricity for a single residential household in rural area in Jordan. The complete design steps for the suggested household loads are carried out. Site radiation data and the electrical load data of a typical household in the considered site are taken into account during the design steps. The relia...
