In this work an unconditionally hiding auditing procedure for distributed (cloud) storage solutions is introduced. There is only one multi-party computation (MPC) scheme providing auditability which computationally protects the inputs of the computations. Building on this, we propose a computationally hiding solution that uses bilinear maps and therefore produces no additional overhead in the online...
The focus of this paper is to examine a controller for a battery energy storage system (BESS), which would reduce the number of deep discharge cycles, with a minimal effect on the regulation services provided by the BESS. Reducing the number of cycles will extend the life expectancy of the BESS, making it a more viable option for the integration of renewable energy onto the power system. To achieve...
For 1.0V operation NAND flash memory, heterogeneously integrated voltage generator is proposed and experimentally demonstrated. The proposed 2-stage boost converter uses high voltage (HV) transistors of standard CMOS process as the 1st stage and HV transistors of NAND flash process as the 2nd stage. The intermediate load capacitance is adaptively adjusted according to the number of NAND flash chips...
Hamming codes are the first nontrivial family of error-correcting codes that can correct one error in a block of binary symbols. In this paper we extend the notion of error-correction to error-reduction and present several decoding methods with the goal of improving the error-reducing capabilities of Hamming codes. First, the error-reducing properties of Hamming codes with standard decoding are demonstrated...

A test set-up has been developed to examine immunity of electronic circuits exposed to the nearby flash magnetic field component. The test set-up generates an impulse current to simulate the nearby flash, and the impulse waveform is determined by the standard AECTP 250, in compliance with the military standardNO-16-A002:2015.
An inspection of signal processing approach in order to determine the number and distance of objects in the sea is conducted in this paper. In recent researches, a great emphasize is put on determining the number and distance of objects in the sea. But unfortunately, it's a difficult task due to the badly effect of high absorption, long propagation delay as well as dispersion. However, besides SONAR...
In aircraft applications, there has been an increasing trend related with the More Electric Aircraft (MEA), which results in rapid rise in the electrical power demand on-board. One of its goals lies in minimizing weight and volume of the electrical subsystem while maintaining good power quality and efficiency. The main purpose of this paper is to present and analyze an electrical design of a three-phase...
We provide a simple method, using Gröbner bases over modules, to compute multivariate polynomial greatest common divisors. The approach we show is flexible, adaptable to algebraic extensions of the rationals or prime fields, and is notably faster than prior methods that work with Gröbner bases. It can be used in situations where sparse interpolation might be difficult to implement, e.g. when there...
This paper presents a fair and non-discriminatory method in losses charge allocation. Traditionally, the method of allocating the charge to the consumer (generators and loads) is widely based on bilateral contract or postage stamp methods. Recently, the introduction of power tracing in searching the true sense of losses allocation in the real system has been implemented. However, this method requires...
In order to use the stable biomass resources that exist in rural areas, we have developed a small bio-methane gas engine generator that can be applied to various methane gas compositions. Different from other conventional researches, we added auxiliary devices such as the surge tank, extra carburetor and ECU to our conventional gas engine generator, instead of alternating the basic structure of the...
The use of expert knowledge is always more or less afflicted with uncertainties for many reasons: Expert knowledge may be imprecise, imperfect, or erroneous, for instance. If we ask several experts to label data (e.g., to assign class labels to given data objects, i.e. samples), we often state that these experts make different, sometimes conflicting statements. The problem of labeling data for classification...
The Bundeswehr Research Institute for Protective Technologies and NBC Protection (WIS) is responsible for the evaluation of the hardness of the German armed forces' systems and devices against the threats from a nuclear electromagnetic pulse (NEMP). For this reason a NEMP test procedure has been established at the WIS, which is meanwhile accredited for performing NEMP qualification tests. The test...
The price of electricity in the Mid-Atlantic (PJM) region of the United States increased during the “Polar Vortex” at the beginning of 2014. Transmission lines were congested because of high demand during the extreme cold weather. The natural gas price for electricity generation increased more than 35% at the end of 2013. Energy Storage Systems (ESS) would have helped the system to overcome many difficulties...
The traditional method of fitting an approximate cumulative probability distribution to a data set is to bin the data in narrow bins and obtain a step function approximation. This technique suffices for many applications, but the resulting object is not a differentiable function making recovery of the underlying probability distribution function impossible. In this study, a unique group theoretic...
The NERC's Control Performance Standards (CPS) represent a great flexibility in relaxing the control of generating resources and yet assuring the stability and reliability of interconnected power systems. The design enhancement of Automatic Generation Control (AGC) plays a vital role in meeting these challenges. This paper for the first time provides a mathematical formulation for AGC in the context...
The need for flexible service provision has dramatically increased in recent years due to the increased penetration of variable energy resources, as has the need to ensure fair access to service provision from an increasingly diverse array of resources. In response to these needs, this study develops a new analytic optimization formulation for the clearing of day-ahead markets based on swing contracts...
The recent amendment to the IEEE Standard for Interconnecting Distributed Resources with Electric Power Systems (IEEE Std. 1547a-2014) is unleashing the application of advanced inverter functionalities to help mitigate voltage regulation problems commonly encountered in areas with high levels of PV penetration. This paper describes the experimental testing of some of the important autonomous functionalities...
This paper investigates the wideband nonlinear vector network analyzer (NVNA) phase calibration method by using a group of narrowband multisine standards and the phase alignment technique. The NVNA test-bed is obtained with a wideband multisine phase reference and a vector network analyzer (VNA), and covers a modulation bandwidth of 80 MHz on a dense spectral grid of 100 kHz. In order to calibrate...
In this paper we propose a new event detector for control systems with a PIplus controller. Its main feature is its capability of filtering the noise in a very effective way, by generating a quantized signal. Practical guidelines are given for the selection of the parameters. Simulation results show the efficacy of the technique and that it outperforms the use of standard use of a Butterworth low-pass...
