In this paper, the proposed shunt regulator is presented. Compared with a series voltage regulator, the shunt voltage regulator gives wideband power supply rejection (PSR) and fast transient response at the expense of large quiescent current. In this paper, a novel shunt regulator architecture is proposed to achieve the genuine characteristic of a shunt regulator with small quiescent current. T...

The shunt-LDO regulator is a new regulator concept which combines a shunt and a Low Drop-Out (LDO) regulator. Designed as an improved shunt regulator to match the needs of serially powered detector systems, it can also be used as a pure LDO regulator for general application in powering schemes requiring linear regulation. The flexibility of the design makes the shunt-LDO regulator a good candid...

This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...

In the modern world, electric drive has tasks of different nature, depending on application and technological process. At moment, induction drives, which operate by direct start, are widely used. This method negative factors: high starting currents at launch; impact loads mechanical system. During continuous running mode motor with its resource system is reduced. Thyristor voltage regulators us...

Abstract Balancing a bipedal robot movement against external perturbations is considered challenging and complex topic. This paper discusses how the vibration caused by disturbance has been tackled Linear Quadratic Regulator, which aims to provide optimal control system. A simulation was conducted on MATLAB in order prove concept. Results have shown that linear quadratic regulator successful st...

A lthough most RNA splicing occurs in the nucleus, HAC1 and XBP1 mRNAs are spliced in the cytoplasm during ER stress. On page 565 , Yoshida et al. demonstrate that in the case of XBP1 both the unspliced and spliced RNAs produce functional proteins and together the proteins form a feedback system that controls the duration of the stress response. When unfolded proteins accumulate in the ER, sens...

In Drosophila, the morphological diversity is generated by the activation of different sets of active developmental regulatory genes in the different body subdomains. Here, we have investigated the role of the homothorax/extradenticle (hth/exd) gene pair in the elaboration of the pattern of the anterior mesothorax (notum). These two genes are active in the same regions and behave as a single fu...

Researchers in the field of epigenomics are developing more nuanced understandings of biological complexity, and exploring the multiple pathways that lead to phenotypic expression. The concept of degeneracy-referring to the multiple pathways that a system recruits to achieve functional plasticity-is an important conceptual accompaniment to the growing body of knowledge in epigenomics. Distinct ...

The present article is a sequel of the article"Fislab the Fuzzy Inference Tool-Box for Scilab"and it represents the practical application of:"The development of the Fuzzy regulator with an input and an output in Fislab". The article contains, besides this application, some functions to be used in the program, namely Scilab functions for the fuzzification of the firm information, functions for t...

We derive the maximum entropy of a flow (information utility) which conforms to traffic constraints imposed by a generalized token bucket regulator, by taking into account the side information present in the randomness of packet lengths. Under constraints of maximum aggregate tokens and maximum aggregate bucket depth, information utility is maximized only if the generalized token bucket regulat...
