BACKGROUND Rhodnius prolixus is the main vector of Chagas disease in Venezuela. Here, domestic infestations of poor quality rural housing have persisted despite four decades of vector control. This is in contrast to the Southern Cone region of South America, where the main vector, Triatoma infestans, has been eliminated over large areas. The repeated colonisation of houses by silvatic populatio...

In this paper we investigate the execution of Ab and AT b, where A is a sparse matrix and b a dense vector, using the Blocked Based Compression Storage (BBCS) scheme and an Augmented Vector Architecture (AVA). In particular, we demonstrate that by using the BBCS format, we can represent both the direct and the transposed matrix for the purposes of matrix-vector multiplication with no additional...

We describe the development of a novel positive-selection vector, RHP-AmpS, that is suitable for seamless cloning and high-level protein expression in Escherichia coli. In this vector, beta-lactamase (Bla) was rendered nonfunctional by replacing the codon for the C-terminal amino acid of the beta-lactamase gene (bla) with a stop codon. Insertion of a target gene in the correct orientation (tail...

in this paper, a recurrent fuzzy-neural network (rfnn) controller with neural network identifier in direct control model is designed to control the speed and exhaust temperature of the gas turbine in a combined cycle power plant. since the turbine operation in combined cycle unit is considered, speed and exhaust temperature of the gas turbine should be simultaneously controlled by fuel command ...

this paper proposes an optimal power flow (opf) algorithm by direct load control (dlc) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. the cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with dlc programs. the load curtailment cost is based ...

This paper includes modeling and simulation of 180 MW units of pumped storage power plant with Variable speed machines. In this method, voltage source inverters are used instead of traditional cyclo-converters. This paper aims to control the voltage source inverters and maintain DC voltage at a constant value. AC/ DC/ AC converter is used in system configuration structure in order to control an...

Direct Torque Control with Multilevel Inverter (DTC-MLI) has emerged recently in high dynamics AC drives fields for induction machines or permanent magnet machines application. In this paper, a review on a variety of techniques and concepts of direct torque control of multilevel inverter-fed induction machines is presented. The techniques and concept involved are classified as follows: Look-up ...

The presented paper deals with the implementation of the Switching Table Based Direct Torque Control (ST-DTC) in the matrix converter-fed induction motor drive. In order to improve the control of the matrix converter input power factor, the use of the simplified Indirect Space Vector Modulation (ISVM) was proposed. To verify the feasibility of the proposed solution, experimental results were pr...

The RAK DEK operating unit is a standalone access control system. This unit, and its more advanced versions, are widely used in Slovakia to protect entrance doors to block of flats. In this paper we have studied security of RAK DEK with respect to timing attack. We have tried two attack vectors. This system shows to be invulnerable to our first attack, but we have succeeded with the other attac...
