This paper presents a methodology for designing bipartite tables for accurate function approximation. Bipartite tables use two parallel table lookups to obtain a carry-save (borrow-save) function approximation. A carry propagate adder can then convert this approximation to a two’s complement number or the approximation can be directly Booth encoded. Our method for designing bipartite tables, ca...

For a simple multiplier block FIR filter design, we compare the effects on power consumption of using direct versus transposed direct forms, tree versus linear structures and carry-save (CS) versus carry-ripple (CR) adders (for which multiplier block algorithms have been designed). We find that tree structures offer power savings, as expected, as does transposition in general but not always. Se...

In this paper we give a systematic analysis of the relationship between imbalance and overlap as factors influencing classifier performance. We demonstrate that these two factors have interdependent effects and that we cannot form a full understanding of their effects by considering them only in isolation. Although the imbalance problem can be considered a symptom of the small disjuncts problem...

This paper presents, low power signed and unsigned fixed-width multipliers using the column bypassing technique with carry save adder array structure. We have decomposed the partial products into two parts and executed them in parallel to reduce the delay of proposed fixed-width array multiplier. The proposed multiplier reduces the power consumption by skipping the unwanted switching activity w...

About one fourth of the world population, living in South Asia region are at an increased risk atherosclerotic cardiovascular diseases (ASCVD).1,2 Pakistan’s population comprises over 200 million inhabitants Asian origin. According to a recent study, more than 30% Pakistani individuals were high (>7.5%) 10 years ASCVD event. Smoking, diabetes (type II), systemic hypertension, and cholesterol...

We present Save ‘Em, an augmented reality-based computer game designed to explore the universal challenge of making computer games more immersive, entertaining and fun. As in the classic computer game Lemmings, Save ‘Em is based on maneuvering a group of slow-witted characters called Dudes through a treacherous maze. Using augmented reality techniques, Save ‘Em places virtual game entities dire...

W hen a person suffers a heart attack, the best clinical outcomes are achieved when he or she is treated within two hours of the onset of acute symptoms. Yeatment benefits decline as further time elapses. Health care providers have instituted various communications and medical strategies to reduce the time between onset and treatment. Among these strategies arc patient education initiatives, sp...

Use of information and communication technology is becoming popular with time as this technology is coming with a lot of lavishness so people are demanding more of it. Electronic items have taken a status symbol in our lives. In India rich class is using up to date devices like cell phones, laptops, computers, microwave ovens, fridge, televisions etc and then pass it on to the poor class. There...

This article presents a physical biology approach to understanding organization and segregation of bacterial chromosomes. The author uses a “piston” analogy for bacterial chromosomes in a cell, which leads to a phase diagram for the organization of two athermal chains confined in a closed geometry characterized by two length scales (length and width). When applied to rod-shaped bacteria such as...
