An extensive data search among various types of developmental and evolutionary sequences yielded a `four quadrant' model of consciousness and its development (the four quadrants being intentional, behavioural, cultural, and social). Each of these dimensions was found to unfold in a sequence of at least a dozen major stages or levels. Combining the four quadrants with the dozen or so major level...

This paper proposes a thrust estimation scheme for marine propellers in four-quadrant operations. To calculate the thrust and torque coefficients of screw propeller in four-quadrant, a Chebyshev fit expression of the propeller properties in four-quadrant for surface vessel is given, and then it is changed into an ordinary polynomial expression. These expressions are suitable for calculating the...

AIM To assess the value of nipple and quadrant sections in mastectomy specimens for carcinoma in detecting Paget's disease and multifocal carcinoma. METHODS Two hundred and forty eight consecutive mastectomies performed for carcinoma were reviewed. The presence of Paget's disease of the nipple and mode of identification of any multifocal carcinoma was recorded. RESULTS Nipple sections showe...

Assessing the root system and its tensile strength is necessary for determine the impact of roots in increasing the soil shear strength. The present study aims to investigate effects of slope and flow of riverbank on root system of riparian POPULOYS trees. In a relatively direct interval, 6 riparian POPULOYS trees were chosen on the slope of Simereh riverbank. To assess the root system, the cir...

In this paper, a compact low-power (LP) low-voltage (LV) metal–oxide–semiconductor-only (MOS-only) variable gain amplifier (VGA) is introduced. This amplifier based on complementary MOS (CMOS) transistors operating in strong inversion is composed of a pseudo-exponential current-to-voltage converter, analog multiplier, and output stage. The gain of the amplifier is controlled exponentially by a ...

This paper presents a well-structured modified Booth encoding (MBE) multiplier which is applied in the design of a reconfigurable multiply-accumulator (MAC) core. The multiplier adopts an improved Booth encoder and selector to achieve an extra-row-removal and uses a hybrid approach in the two’s complementation circuit to reduce the area and improve the speed. The multiplier is used to form a 32...

This paper focuses on the circuit aspects required for an on-chip, on-line SoC large-scale Field Programmable Analog Array (FPAA) learning for Vector-Matrix Multiplier (VMM) + Winner-Take-All (WTA) classifier structure. We start by describing the VMM+WTA classifier structure, and then show techniques required to handle device mismatch. The approach is initially explained using a VMM+WTA as a tw...

this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...

We are focusing on the development of a highly compact neural net weight function based on the use of EEPROM devices. These devices have already proven useful for analog weight storage, but existing designs rely on the use of conventional voltage multiplication as the weight function, requiring additional transistors per synapse. A parasitic capacitance between the floating gate and the drain o...
